Cyanide Poison

Let's start by understanding exactly how cyanide kills you. In simple terms, cyanide prevents cells from using oxygen to make energy molecules.

The cyanide ion, CN-, binds to the iron atom in cytochrome C oxidase in the mitochondria of cells. It acts as an irreversible enzyme inhibitor, preventing cytochrome C oxidase from doing its job, which is to transport electrons to oxygen in the electron transport chain of aerobic cellular respiration. Now unable to use oxygen, the mitochondria can't produce the energy carrier adenosine triphosphate (ATP). Tissues that require this form of energy, such as heart, muscle cells, and nerve cells, quickly expend all their energy and start to die. When a large enough number of critical cells die, you expire as well. Death usually results from respiratory or heart failure.

Immediate aymptoms include headaches, nausea and vomiting, dizziness, lack of coordination, and rapid heart rate. Long exposure symptoms include unconsciousness, convulsions, respiratory failure, coma and death.

A person exposed to cyanide may have cherry-red skin from high oxygen levels, or dark blue coloring, from Prussian blue (iron-binding to the cyanide ion). In addition to this, skin and body fluids may give off an almond odor.

The antidotes for cyanide include sodium nitrite, hydroxocobalamin, and sodium thiosulfate.

A high dose of inhaled cyanide is lethal too quickly for any treatment to take effect, but ingested cyanide or lower doses of inhaled cyanide may be countered by administering antidotes that detoxify cyanide or bind to it. For example, hydroxocobalamin, natural vitamin B12, reacts with cyanide to form cyanocobalamin, which leaves the body in urine.

These antidotes are administrated via injection, or IV infusion.

Cyanide is actually a lot more common than you'd think. It's in pesticides, fumigants, plastics, and electroplating, among other things. However, not all cyanide are so poisonous. Sodium cyanide (NaCN), potassium cyanide (KCN), hydrogen cyanide (HCN), and cyanogen chloride (CNCl) are lethal, but thousands of compounds called nitriles contain the cyanide group, yet aren't as toxic. They still aren't terribly good for you, so I wouldn't go around ingesting other cyanide compounds, but they're not quite as dangerous as the lethal kind.

Thank you for reading, have a lovely day :)

Unraveling the Tapestry of Cellular Energy: A Comprehensive Voyage through the Electron Transport Chain 🧬⚙️

Prepare for a deep dive into the labyrinthine pathways of the Electron Transport Chain (ETC), where molecular machinations weave the intricate tapestry of cellular respiration. In this odyssey, we'll navigate the complexities with surgical precision, leaving no nuance unexplored.

1. Prelude at Complex I (NADH Dehydrogenase):

The ETC's overture commences at Complex I, where NADH, a product of glycolysis and the Krebs cycle, surrenders its high-energy electrons. Traverse the serpentine route of flavin mononucleotide (FMN) and a succession of iron-sulfur clusters, witnessing the orchestrated dance that propels electrons toward the enigmatic ubiquinone (Q).

2. Interlude with Succinate (Complex II - Succinate Dehydrogenase):

As the symphony progresses, Complex II takes the stage with succinate as its protagonist. Succinate dehydrogenase, fueled by succinate from the Krebs cycle, orchestrates a parallel electron flow. Behold the ballet of electrons navigating iron-sulfur clusters and flavin adenine dinucleotide (FAD), converging upon ubiquinone (Q) in a seamless choreography.

3. Cytochrome Waltz (Complex III - Cytochrome bc1 Complex):

The narrative crescendos at Complex III, the cytochrome bc1 complex, where Q takes center stage. Through a series of mesmerizing redox reactions, Q gracefully shuttles electrons to cytochrome c. This transient dancer becomes the ethereal messenger, ferrying electrons with finesse towards the climactic rendezvous at Complex IV.

4. Grand Finale with Complex IV (Cytochrome c Oxidase):

In the climactic finale, Complex IV, personified by cytochrome c oxidase, awaits the electron ensemble. Watch as electrons, guided by a cascade of copper and iron centers, engage in a captivating pas de deux with molecular oxygen. Witness the alchemical metamorphosis as oxygen is humbly transmuted into water, marking the zenith of our electron saga.

5. Proton Symphony and ATP Synthesis:

Simultaneously, the proton symphony unfolds as protons, displaced during electron transit, accumulate in the intermembrane space. This sets the stage for a grand energy transfer. The finale crescendos with protons flowing back through ATP synthase, a molecular turbine, culminating in the synthesis of ATP—the lifeblood of cellular energy currency.

ermmie wormiee....can you explain how light dependant reactions work I'm genuinely kinda lost on that part of AP Bio like everything else makes sense but unit 3 (enzymes photosynthesis and cellular resp) is genuinely my OP

Ok, so I don’t know how much you have to know so let’s just get into it. It’s not that hard once you get it.

Also please keep in mind that I studied all of this in German so I’m sorry if some things are worded weirdly.

So, there are two photosystems (PSII and PSI) in plants. As you can see in this pic, the whole reaction starts with PSII, not PSI — that’s because PSI was discovered first. (But that’s not really important.)

Photosystems are able to absorb photons (that come from the light) and produce a high energy electron! As you can see in this pic, PSII absorbs the photon, creates a high energy electron and sends it through an electron transport chain (Plastoquinone - that’s a molecule btw) to the Cytochrome b6f complex and from there to PSI.

PSII uses water as an electron donor! That is very important because that’s how oxygen gets created as a by-product.

(sciencefacts.net)

PSI absorbs the photon again and produces another high energy electron which converts NADP+ to NADPH.

The big question is: how does the plant create ATP now?

That happens through non-cyclic photophosphorylation. See all those H+ protons? Whereas there is a bunch inside the thylakoid lumen, there isn’t much in the stroma.

That leads to a concentration compensation. So all those little protons that have been produced during the reaction actually go through the ATP-synthase into the stroma. Thus, the ATP-synthase creates ATP!

I also had to remember this, I don’t know if you do but if you have any questions about it, feel free to ask:

(istudy.pk)

All you need to know is basically:

Light hits PSII. Light = energy. PSII needs energy to turn electron (water = electron donor) into a high energy electron. High energy electron travels. H+ protons get produced during reactions. PSI needs energy. High energy electron converts NADP+ to NADPH (we need that for our Calvin cycle later). Bunch of protons travel through ATP-synthase —> we have ATP now!!!

I hope this makes somewhat sense. As I’ve mentioned, I had to remember all of this in German so yeah it might be a bit messy. If there’s anything unclear, feel free to send another ask!

[anulithots]

go ahead & talk about caspases

So I'm using this article for my ramblings (I annotated it and went feral): Paradoxical roles of caspase-3 in regulating cell survival, proliferation, and tumorigenesis - PubMed (nih.gov)

The research article, and how to storyfy it

SO the crux of this article - being called the ‘paradoxical functions of caspases’ and all - is that capase-3’s cause cell proliferation and cleavage in more than just apoptosis, implying that their function is widespread throughout the cell.

Now that sounded formal. Here’s how I’ll story-fy it. So Cassiah the Caspase-3 wants to not be attached to the world because their purpose is to destroy it. If death lies at the end of this then why suffer the pain of wanting something from this? However, because of thrill life offered after the Caspase-9 first awoke them, they want their life to mean something. They want their life to be so full of meaning and fulfillment at every moment that death wouldn’t matter much anyways.

So with the dual purposes of caspase-3’s, the question of whether Cassiah is meant to cause apoptosis or something else is uncertain. What Cassiah knows is that they want to fulfil their itches and urges to kill/cleave proteins

(We’ll have cleaving be a sort of ‘blood transformation’. So they must be cut in a certain way… similar to those blood sigil things)

They know that cleaving other proteins would give their buzzing energy in a search for more a rest, that would be the moment they finally are content.

Now the Caspase-9 that awoke Cassiah believes that Cassiah must meet the expectations of their purpose. Don’t ask questions. If Cassiah is meant to cause the death of the cell then so be it. Attempting to avoid this fate would only cause more heartache. ‘This is real. If you get caught in dreams of grandeur, as you, as a caspase… then I can only wish that you realize the truth before the end.’

Casapse-9/intrinsic pathway activation (this one involves cytochrome-c from the mitochondria, fun fun):

In essence, external growth factors cease, the outside world doesn’t want anything from this cell anymore. Stressors such as ‘viral infections, hypoxia, hyperthermia, oxidative stress, and intrinsically detected stress signals resulting from exposure to toxic chemical or radiation exposure’. So the outside world is cut off, something on the inside is wrong.

As far as signaling goes, I imagine something akin to carrier pigeons? … I still have to figure out what sort of style of world this is, but honestly I’m leaning more and more towards ‘biology first then the rest melds around that’. So either more sentient ‘carrier pigeon’ types or little floating things (magic sparkles of sorts) that land upon certain proteins or other receptors that cause some sort of shift or change. In this case. Stress signals. They cause certain alarms to go off, such as this pathway. So is everyone aware that the world might end? Yes and no. It depends on who you are, and given that cell signaling is complex, I imagine that everyone has their own idea/awareness of what is going on. If a protein goes about their day and recognizes a little signal floating around among the slew, the hustle and bustle of things floating around, then that might be a cause for concern.

From here the signals cause the mitochondrial membrane to be more permeable.

Now for membranes, their built of this ‘ramen type thing’ (similar to how people build all sorts of things with ramen… but more magical and fancy and such )

… so we’re going with magical absurdism here.

Anywho, so the phospholipid bilayer… would probably look around the same? Heads facing the outside, so it’s bumpy, along with the inside looking like stringy ramen. So that becomes looser…

and things

begin

to

leak.

SUCH AS CYTOCHROME C!

I forget what this was used for in cellular respiration because…. cellular respiration… I’d need to review some of that. If I remember correctly, it was part of oxidative phosphorylation… the electron transport chain?

So that starts bleeding into the surrounding space, which forms a apoptosomal complex that includes caspase-9.

Storyfying wise - Caspase-9 has lied dormant in this biomechanical machine (sci-fi is slowly but surely becoming more intriguing to me), waking rarely, always a hush hush if they do. For that, everyone knows (at least everyone in the know knows) that could end in disaster.

So the cytochrome c causes that biomechanical mass to awaken, a sore and tired and… dread-filled caspase-9 within.

(We’re going to be looser with personalities needing backstories to explain every facet here for my own sanity)

This caspase-9 then - still shaking off the aches of dormancy - awakens their ‘younger sibling who will cause the end of the world’

And here, they feel a touch of pity. It’s not fair. Really. It’s not fair yet this is what it is, how the Caspase-9 wishes it didn’t have to do this, but the universe itself is against any rebellion, and they don’t want any pain unto themself.

Caspase-3s’s are these little caspase-3 assassins that kill off caspase-3’s. The way this whole thing with all the opposing signals works here is that… this is an entire world here. IN order to have the ‘right thing’ done, there must be conflict, someone who wins out in the end, it’s a fragile balance.

So the Caspase-9… now here’s the part where I’m still figuring it out… it’s okay but it could be better…

The caspase-9 manages to save only one of the caspase-3’s from the caspase-3s, Cassiah, who does seem a little shaken from the whole ordeal, and a little hesitant to follow their whole purpose, they don’t leave immediately… In fact, they aren’t really shaken, they are thrilled.

Oh. What an issue.

The Caspase-9 easily forgets the other caspase-3’s, and this more than anything frightens Cassiah, while the Caspase-9 tells them that this, whatever this is, they just escaped with their lives here. They could’ve easily been killed as well, then the Caspase-9 would need other caspase-3’s to replace Cassiah. THe world doesn’t care. There’s no solace outside of the promise of being useful. Any attempt otherwise ends in heartache.

Now here Cassiah wonders what would’ve happened if they had died right then, before they got the chance to fully experience something, it wouldn’t have been such a pain then. It would’ve been like sleeping more after a brief interruption.

Does the world care? Is there a meaning to this?

Perhaps not.

But they want a meaning to this. To their life. They want to live and savor every moment of it so even if they had died in the next, they could’ve died fulfilled, full, with a meaning to even death.

So Casaiah’s really fighting against their own desire to live well with the promise of a meaningless but purposeful existence, one that is guaranteed not to hurt, to be satisfying in the end, as long as they don’t resist.

(Sigh I won’t really get this until I start writing Cassiah prose)

the dual purpose of caspase-3

Caspase-3’s cleave other proteins, inhibitors, and such. Again, I imagine this would involve a high-stakes kidnapping a blood-sigil-type-thing where Cassiah cuts just so for the protein to change purpose/activate or deactivate.

Now part of what they do is cut inhibitors, for instance, they cut an inhibitor that keeps DNA from fragmenting. An inhibitor inhibits caspase-activated DNAse, once Caspse-3 removed the inhibitor, caspase-activated DNAse condenses and cleaves DNA at ‘interneucleosomal linker sites between nucleosomes’

OTHER RESULTS: so, because of Caspase-3’s other downstream targets ‘phosphatidylserine from the inner layer of the plasma membrane’ leaks from the membrane to the outside of the cell. It binds to the cell surface and calls phagocytes to the cell to consume it. This is a preliminary sign of apoptosis

~Storyfying this - So BLOOD SIGILS CARVED INTO THE FLESH.

ANd I doubt articles will have the specific targets because cell signaling is…. complicated so say the least, so I have some creative liberty here.

In Cassiah’s little adventures around the cell, they have sudden thoughts to do the deed. They will have to kidnap them, take them somewhere private and carve the sigil into flesh, they will change shape as a result.

As far as their morals go with this, they don’t want to be forgotten, so they are perfectly fine with doing the deed itself (what’s more memorable than a life-changing event?) however apoptosis is possible. Apoptosis, in which everything will be forgotten. It wouldn’t have mattered if Cassiah existed or not, their life wouldn’t have meant anything, and that scares them more than anything .

So despite their desire to do the whole blood sigil thing, they avoid it, they even save others for the sake of avoiding apoptosis.

other things:

Caspase-3 activity causes ‘nonautomatous and cell autonomous (or direct) mechanisms of initiation and execution’

nonautomatous refers to the adjacent cells proliferating to replace the apoptotic cell

Caspase-3 activates pathways, starts pathways, interferes with pathways that can lead to tissue growth and wound healing. (nonautonomous) Which is not so fun for tumors and such…

cell autonomous refers to the apoptotic cell itself and how Capase-3

capase-3’s are also known to cleave substrates during the M to G1 transition step in mitosis even when apoptosis will not occur

“This has been explained by caspse-3 mediating the cleavage of p21 (the cyclin-dependent kinase [CDK] inhibitor) at its C terminus, thereby disrupting the ability of p21 to interact with proliferating cell nuclear antigen (PCNA) leading to cell cycle inhibition” ←- basically Caspase-3 can start the cell cycle which IS CRAZY TO ME AAAAAAAAAAAAAAAAAAAAAA

SO STORY WISE

There will definitely be an episode in which Cassiah finds out that they could be involved in mitosis rather than apoptosis. So they spend time around cyclin-dependent kinases for the day and see if they feel any ‘blood sigil urges’

The nonautomnous parts of this are fun, but since they are outside the scope of the cell, I am unsure of if I can include them, but it would be fun if I could because it’s peak angst. (being replaced and such.)

ALSO ALSO

procaspase-3 affects MITOCHONDRIAL REGULATION

“In this case, the suppression of Caspase-3 expression led to mitochondrial dysfunction, accumulation of damaged mitochondria, and downregulation of key transcriptional activators of mitochondrial biogenesis”

PEOPLE POEPLE SKJDSKLFJKDLSJ AAAAAAAAAAAa

SO BASICALLY

I was wrong that procaspases float in a void and are deactivated. They actually work to regulate the mitochondria. KLJDFKJDSLKF but here’s the thing. I built Cassiah’s character off of existing first as floating within the void. If that’s not the case, then I need to change thier entire character to fit around this more. Hopefully it will be easier… maybe…. sighhhh

Now as fun as researching about caspases has been, it’s really for the purpose of character building, now I want to look more into diving deeper on all the AP bio topics and fully fleshing out this world and the themes.

ANd now I also have to rework Cassiah’s character after finding out about this mitochrondria thing…. sigh sigh I should’ve finished the article before I started.

ERM... yes. OKAY SO biology taglist... you do not have to read all this.

The lovely biology taglist: @vamp4ever @bonesbeetle @neurospicy-salsa @sea-dwelling-wizard

Mitochondrial Dysfunction in Primary Mitochondrial Disease

Introduction

Primary Mitochondrial Disease (PMD) refers to a group of genetic disorders resulting from defects in mitochondrial function. Mitochondria play a crucial role in energy production through oxidative phosphorylation (OXPHOS), and their dysfunction leads to a wide spectrum of clinical manifestations affecting multiple organ systems. PMD primarily arises from mutations in mitochondrial DNA (mtDNA) or nuclear DNA (nDNA) encoding mitochondrial proteins, resulting in impaired energy metabolism and increased cellular stress.

Pathophysiology of Mitochondrial Dysfunction

Mitochondrial dysfunction in PMD is primarily caused by defects in the electron transport chain (ETC), which is responsible for ATP synthesis. The ETC comprises five protein complexes embedded in the inner mitochondrial membrane. Mutations affecting these complexes disrupt ATP production, increase the production of reactive oxygen species (ROS), and lead to metabolic imbalances such as lactic acidosis.

Complex I (NADH: ubiquinone oxidoreductase) and Complex IV (cytochrome c oxidase) deficiencies are among the most common defects in PMD. These impairments reduce the efficiency of ATP production, leading to an energy crisis in high-demand tissues such as the brain, muscles, and heart. Additionally, defects in mitochondrial dynamics, including fission and fusion processes, further contribute to cellular dysfunction.

Genetic and Biochemical Basis

PMD is genetically heterogeneous, with mutations in over 350 known genes. These mutations can be inherited in a maternal, autosomal recessive, or dominant manner. Some commonly affected genes include:

MT-ND genes (encoding Complex I subunits)

SURF1 gene (involved in Complex IV assembly)

POLG gene (critical for mtDNA replication and maintenance)

PDHA1 gene (encoding a subunit of the pyruvate dehydrogenase complex)

Mutations in these genes impair the synthesis of key mitochondrial components, leading to energy production failure, oxidative stress, and apoptotic signaling.

Impact on the Nervous System

The nervous system is highly dependent on mitochondrial energy production, making it particularly susceptible to dysfunction. Mitochondrial defects in PMD often manifest as progressive neurodegenerative disorders, including:

Developmental delay and cognitive impairment

Seizures and epilepsy

Hypotonia and muscle weakness

Ataxia and movement disorders

Peripheral neuropathy

Histopathological findings in affected individuals often reveal spongiform degeneration, gliosis, and neuronal loss, particularly in the basal ganglia, cerebellum, and brainstem. These changes contribute to progressive neurological decline.

Effects on Other Organ Systems

Beyond the nervous system, mitochondrial dysfunction in PMD affects multiple organs due to the ubiquitous need for ATP. Key systemic manifestations include:

Musculoskeletal System: Myopathy, exercise intolerance, and rhabdomyolysis are common due to inadequate ATP supply for muscle contraction and maintenance.

Cardiovascular System: Cardiomyopathy, conduction abnormalities, and arrhythmias result from mitochondrial defects in cardiac muscle, leading to impaired contractility and electrical activity.

Metabolic System: Lactic acidosis and metabolic decompensation occur due to defective oxidative metabolism, leading to systemic energy deficits.

Gastrointestinal System: Dysmotility, feeding difficulties, and pancreatic dysfunction are observed, contributing to malnutrition and failure to thrive.

Endocrine System: Mitochondrial dysfunction affects hormone-producing glands, resulting in diabetes, hypothyroidism, and adrenal insufficiency.

Cellular and Molecular Consequences

Mitochondrial dysfunction in PMD leads to several cellular-level consequences, including:

Increased ROS production, causing oxidative stress and damage to lipids, proteins, and DNA.

Dysregulation of apoptosis, leading to premature cell death and tissue degeneration.

Defective calcium homeostasis, impairing neuronal and muscular function.

Impaired mitochondrial biogenesis, reducing the ability of cells to compensate for energy deficits.

Conclusion

Primary Mitochondrial Disease is a complex, multisystem disorder driven by genetic defects in mitochondrial function. The resulting energy production failure impacts the nervous, muscular, cardiovascular, metabolic, and endocrine systems, leading to severe clinical manifestations. Understanding the molecular and biochemical mechanisms underlying PMD is crucial for advancing diagnostic and research efforts. Continued investigation into mitochondrial biology and genetic contributors will enhance our knowledge of this debilitating disease.

The Science Behind Copper: Why It's Essential for Your Health

Copper, a trace mineral found in various foods and essential for the body's overall function, plays a significant role in maintaining health. Despite being required in small amounts, copper is indispensable for numerous physiological processes, including energy production, connective tissue formation, brain function, and the immune system. Understanding the science behind copper and its health benefits sheds light on why this mineral is vital for our well-being.

The Role of Copper in the Body

Copper is a cofactor for several enzymes known as cuproenzymes. These enzymes facilitate various biochemical reactions in the body. One of the critical functions of copper is its role in energy production. Copper is a component of cytochrome c oxidase, an enzyme in the mitochondria responsible for the final step in the electron transport chain, which generates ATP, the cell's primary energy currency.

Additionally, copper is crucial for the formation and maintenance of connective tissues. Lysyl oxidase, a copper-dependent enzyme, is essential for the cross-linking of collagen and elastin, two proteins that provide strength and elasticity to connective tissues like skin, bones, and blood vessels. This process is vital for wound healing, maintaining the integrity of blood vessels, and ensuring the strength of bones and cartilage.

Copper and the Nervous System

The nervous system relies heavily on copper for optimal function. Copper is involved in the synthesis of neurotransmitters, the chemical messengers that transmit signals between nerve cells. Dopamine-beta-hydroxylase, an enzyme that converts dopamine to norepinephrine, requires copper to function correctly. Norepinephrine is a neurotransmitter essential for mood regulation, alertness, and stress response.

Moreover, copper contributes to the formation and maintenance of myelin, the protective sheath around nerve fibers that ensures efficient transmission of nerve impulses. Copper deficiency can lead to neurological issues, including impaired motor coordination and cognitive function.

Copper's Role in the Immune System

A well-functioning immune system is crucial for defending the body against infections and diseases. Copper enhances the immune system by stimulating the production and activity of immune cells. It helps in the production of white blood cells, including neutrophils and macrophages, which are essential for phagocytosis—the process of engulfing and destroying pathogens.

Furthermore, copper possesses antimicrobial properties. It can kill or inhibit the growth of bacteria, viruses, and fungi, making it an essential element for maintaining immune health and preventing infections.

Sources of Copper and Daily Requirements

Copper is naturally present in a variety of foods. Good dietary sources include shellfish, seeds and nuts, whole grains, dark leafy greens, and organ meats. For most people, a balanced diet provides sufficient copper to meet daily needs. The recommended daily allowance (RDA) for copper varies by age, sex, and life stage, but for adults, it is approximately 900 micrograms per day.

Risks of Copper Deficiency and Toxicity

While copper deficiency is rare, it can occur, especially in individuals with certain genetic disorders, malabsorption issues, or those who rely on parenteral nutrition. Symptoms of deficiency include anemia, weakened immune response, neurological problems, and cardiovascular issues.

On the other hand, excessive copper intake can lead to toxicity, resulting in symptoms like abdominal pain, nausea, vomiting, and, in severe cases, liver damage and kidney failure. Therefore, it is essential to maintain a balanced intake of copper through diet and avoid excessive supplementation unless prescribed by a healthcare provider.

Conclusion

Copper's role in energy production, connective tissue formation, nervous system function, and immune health highlights its importance as an essential mineral. Ensuring adequate copper intake through a balanced diet can support these vital processes and improve overall health and well-being. Understanding the science behind copper underscores why this trace mineral is indispensable for maintaining a healthy body.

Sodium Cyanide Market Trends: Insights and Forecasts

Introduction Sodium cyanide is an odorless chemical compound with the formula NaCN. It is a white, water-soluble solid. NaCN has a wide range of industrial and other applications, but it is also notoriously toxic and has sometimes been used for suicide or murder. Let's explore some key facts about this dangerous chemical compound. Chemical Properties and Structure Sodium cyanide has the chemical formula NaCN and a molar mass of 49.01 g/mol. It dissociates in water to give hydroxide (NaOH) and cyanide (CN-) ions. The cyanide ion is linear with carbon and nitrogen separated by a triple bond. It is this CN- ion that is primarily responsible for NaCN 's high toxicity. NaCN is a white solid that melts at 563°C to give a colorless liquid. It is highly soluble in water. Toxicity and Mode of Action Cyanide is an inhibitor of cytochrome c oxidase, an important enzyme in the mitochondrial electron transport chain. By blocking this enzyme, cyanide essentially prevents aerobic respiration from taking place at the cellular level. This leads to a rapid depletion of oxygen to tissues and ultimately causes death due to hypoxia at the tissue and organ level. The lethal dose of NaCN for adult humans is reported to be 200-300 mg. However, as little as 1-5 grams can prove fatal. The primary symptoms of cyanide poisoning include headaches, dizziness, confusion, convulsions and cardiac arrest. Death by cyanide poisoning usually occurs within minutes to an hour. There is no antidote for cyanide poisoning. Treatment focuses on supportive measures in a hospital environment along with use of antidotes like sodium thiosulfate or dicobalt edetate to combat the effects of cyanide. Industrial Uses Despite its obvious toxicity, NaCN has many beneficial industrial applications primarily due to its ability to dissolve minerals containing precious metals like gold and silver. It is widely used for extraction of these metals via cyanidation process in mining operations. In this process, an aqueous solution of NaCN is used to leach gold from minerals into the water to facilitate separation and recovery of gold. NaCN is also used in some cleaning and metal surface treatment applications. Other uses include: Production of nylon - Sodium cyanide serves as an intermediate for adiponitrile, which is further used to make nylon 6,6. Case hardening - It is used in metallurgy for case hardening of steels to increase wear resistance and hardness. Alkylation - In organic chemistry, NaCN acts as an alkylating agent in production of compounds like acrylonitrile. Accidental and Intentional Poisonings There have been many accidental and intentional deaths reported due to sodium cyanide poisoning over the years. Accidental cases may occur due to occupational exposure in industries using cyanide or due to consumption of cyanide-containing products mistaken as food. Intentional poisonings with cyanide have been reported in cases of suicide or murder. Some high-profile murder cases have involved the use of NaCN by the perpetrator. Given the acute toxicity of cyanide ions, even small amounts ingested intentionally can prove rapidly lethal. Proper safety precautions are a must for any activities involving this deadly chemical salt. Regulation and Safe Handling Considering the high human toxicity of NaCN, it is designated as a schedule 2 substance under the Chemical Weapons Convention. Many countries have strict regulations governing its manufacture, transportation, storage and industrial usage. Workers directly handling NaCN must be properly trained in safety procedures like wearing recommended personal protective equipment. Leakage of cyanide solutions into the environment must also be prevented to avoid toxicity to other organisms. Overall, given the risks involved, sodium cyanide requires controlled and regulated use with utmost precautions taken at all stages to prevent accidental poisonings.

What Should You Know About Red Light Therapy Weight Loss?

Numerous studies have shown that red light treatment, a non-invasive method of low-level laser therapy, can aid in fat loss. While Red Light Body Contouring is not a magic bullet for weight reduction on its own, it has been used successfully by the biohacking community as a supplement to healthy eating and regular exercise to help people shed excess pounds more quickly.

Red light therapy is defined as.

Red light or Body Sculpting Treatmentsis a subset of LLLT that employs the application of bioactive visible and infrared light wavelengths to the affected area. Commonly used photon frequencies include the red end of the visible spectrum (630–660 nm) and the near infrared end (850 nm).

Red light therapy or Body Sculpting Non Surgicalimproves adenosine triphosphate (ATP) production by increasing the availability of oxygen at the fourth step of electron chain transport, when cytochrome c-oxidase is used. Then, localized fat reduction and improved body contouring are possible thanks to adenosine triphosphate.

Some research suggests that Red Light Therapy for Weight Losscan help the body get rid of excess fat by reducing fat cells and then releasing them through the body's natural waste elimination systems. The body's fat cell count drops as a result.

A clinical dermatologist can-do red-light treatment in the comfort of your own home or at a spa. Cost-effective and convenient, Red Light Therapy for Inflammationat home allow you to reap the weight loss advantages of LLLT without leaving the ease of your own home. Studies have revealed that red light treatment can aid with weight loss.

Red light therapy: any risks?

Although red light therapy has been demonstrated to be safe in separate trials, it is better to err on the side of caution. Before beginning a course of red-light therapy, it is wise to consult with your doctor.

A light exposure test should be done before beginning regular use of red-light treatment. This method entails illuminating a small patch of skin with the device's red and infrared lights to see if a reaction occurs.

Red light treatment, whether used at house or in a health club, has been shown in trials to have no serious adverse effects.

Is It Appropriate to Invest in Red Light Therapy?

Red Light Therapy Weight Loss will not be effective unless other crucial lifestyle parameters are also drastically improved. Maintaining a healthy body requires a commitment to both regular exercise and a well-rounded, nutritional diet. Fat loss is increased when combined with red light therapy compared to when either method is used alone.

As a non-invasive method of reducing fat and reshaping the physique, red light therapy has many advantages.

Red light therapy, when combined with a healthy diet and regular exercise, has been shown to be an effective, non-invasive method of accelerating weight loss. Because of the lack of serious safety issues, red light therapy is a great addition to your weight loss arsenal.

Waist, thigh, and hip circumference can all be significantly reduced with regular red light therapy sessions lasting only twenty minutes.

Mitochondrial Dysfunction in Leigh Syndrome

Introduction:-

Leigh Syndrome (LS) is a rare, severe neurological disorder that typically manifests in infancy or early childhood. It is primarily caused by mitochondrial dysfunction, which results in progressive neurodegeneration. This condition affects approximately 1 in 40,000 newborns and is characterized by lesions in the brainstem and basal ganglia, leading to motor and cognitive impairments.

Pathophysiology of Leigh Syndrome

Mitochondrial dysfunction is central to the pathology of Leigh Syndrome. The mitochondria, often referred to as the powerhouse of the cell, generate adenosine triphosphate (ATP) through oxidative phosphorylation (OXPHOS). This process occurs within the electron transport chain (ETC), which consists of five protein complexes embedded in the inner mitochondrial membrane. In LS, genetic mutations disrupt these complexes, impairing ATP production and causing an accumulation of toxic byproducts such as reactive oxygen species (ROS) and lactate.

The most frequently affected complexes in Leigh Syndrome are Complex I (NADH: ubiquinone oxidoreductase) and Complex IV (cytochrome c oxidase). Mutations in nuclear or mitochondrial DNA (mtDNA) encoding subunits of these complexes lead to decreased enzymatic activity, impairing energy production. As neurons have high energy demands, they are particularly vulnerable to mitochondrial defects, resulting in neuronal cell death and progressive neurodegeneration.

Genetic and Biochemical Basis

Leigh Syndrome is genetically heterogeneous, with over 75 known causative genes. Mutations can be inherited in an autosomal recessive, X-linked, or maternal manner, depending on whether the affected gene is in nuclear DNA or mtDNA. Some of the most common mutations occur in:

MT-ND genes (affecting Complex I)

SURF1 gene (associated with Complex IV deficiency)

PDHA1 gene (disrupting pyruvate dehydrogenase complex, leading to lactic acidosis)

Mitochondrial DNA mutations are maternally inherited, while nuclear DNA mutations follow Mendelian inheritance patterns. The variability in genetic origins contributes to the clinical heterogeneity observed in Leigh Syndrome.

Impact on the Nervous System

Mitochondrial dysfunction in LS predominantly affects the central nervous system (CNS), leading to hallmark neuropathological changes. Bilateral symmetrical lesions appear in the basal ganglia, thalamus, cerebellum, and brainstem. These lesions result from energy deficits and ROS-induced damage, leading to demyelination, gliosis, and neuronal loss.

The neurological symptoms of Leigh Syndrome include:

Developmental delay and regression

Hypotonia (low muscle tone)

Dystonia (involuntary muscle contractions)

Ataxia (lack of muscle coordination)

Ophthalmoplegia (paralysis of eye muscles)

Respiratory failure due to brainstem involvement

As the disease progresses, affected individuals experience worsening motor and cognitive impairments, ultimately leading to severe disability and premature death.

Systemic Effects Beyond the CNS

While Leigh Syndrome primarily affects the nervous system, mitochondrial dysfunction also impacts other organ systems. Metabolic abnormalities such as lactic acidosis arise due to impaired oxidative metabolism, leading to energy deficits in multiple tissues. Additionally, cardiac involvement, such as hypertrophic cardiomyopathy, has been observed in some cases, reflecting the high energy demands of the heart.

The gastrointestinal system may also be affected, with symptoms such as feeding difficulties, failure to thrive, and gastrointestinal dysmotility. This further complicates disease management and contributes to the overall severity of the condition.

Conclusion

Leigh Syndrome is a devastating disorder driven by mitochondrial dysfunction, resulting in widespread neurodegeneration and multi-organ involvement. The genetic heterogeneity and complexity of mitochondrial pathology make it a challenging condition to study and manage. Understanding the molecular basis of mitochondrial dysfunction in LS provides crucial insights into the disease mechanism and potential therapeutic avenues, though treatment remains limited. Continued research into mitochondrial bioenergetics and genetic contributions will be essential in advancing our knowledge of Leigh Syndrome and related mitochondrial disorders.

okay no im going to explain this and it will MAKE SENSE and i will not give in to the despair. so this is a representation of the formation of suprarenal steroid hormones. the suprarenal glands are (as the name suggests) right above the kidneys, one on each.

the cortex (or outer layer) of the suprarenal gland is formed out of three zones: zona glomerulosa, zona fasciculata, and zona reticularis. each of these zones contain specific enzymes that have specific roles in the formation of these hormones, and therefore each zone cannot form Every Type of hormone, because it might not contain the specific enzymes necessary for Every Type.

the source of all steroids is cholesterol. so all of these enzymes act on cholesterol to end up with the hormones. the important enzymes are the CYP450 (cytochrome P450), which will hydroxylize a specific carbon.

in the zona glomerulosa, we find P450scc (that will cleave the lateral chain of cholesterol, which is not needed. scc: side chain cleaving). there's also P450c21 and c11, which will respectively hydroxylize the 21st carbon and the 11th carbon. with these enzymes, we can form progesterone, corticosterone, and aldosterone.

in the zona fasciculata, we find P450c17, which will hydroxylize the 17th carbon. so in this area we can form only cortisol and testosterone.

finally, in the zona reticularis, we find P450aro, which will transform androgens into estrogens, so we can only form estradiol.
