Abstract For the first time, the effect of 5- and 10-day soil flooding on the ultrastructure of the leaf mesophyll cells of the psammophyte desert madwort (Alyssum desertorum L.) was investigated. The seeds for the experiments were collected from plants of dry sandy areas of the gully slopes of the ravine forest in the steppe zone of the Dnipropetrovsk oblast. It is shown that a characteristic feature of the leaf photosynthetic cells of this species is the presence of single and large, up to 6 pm, peroxisomes, which are in close contact with chloroplasts and mitochondria, playing a key role in photorespiration. The general organization of palisade parenchyma cells on days 5 and 10 of soil flooding is similar to that in the control. A slight decrease in the size of peroxisomes on day 5 of flooding and its increase on day 10 and more often formation of multivesicular structures (assembly of endomembranes) in the vacuole, which is considered as an autophagy enhancement of the cytoplasm under hypoxia, were noted. Differences in the ultrastructure of chloroplasts under the influence of soil flooding consisted in a significant, almost twofold increase in transient starch, the size and number of plastoglobules, especially on day 10, and swelling of granal and stroma thylakoids on day 10. Changes in the ultrastructure of desert madwort chloroplasts under the influence of soil flooding coincide with those of mesophytes studied in this respect. The obtained data on the chloroplast ultrastructure of desert madwort psammophyte prove the functioning of the photosynthetic apparatus in conditions of short-term soil flooding, which contributes to the survival of seedlings. The subsequent yellowing of leaves and death of plants indicates, as is assumed, the lack of systemic adaptation, primarily metabolic, that is, the transition to anaerobic metabolism, in this species to long-term hypoxia.

Mitochondrial Dysfunction in Type 2 Diabetes
Introduction
Mitochondria, essential for cellular energy metabolism, play a crucial role in bioenergetics and metabolic homeostasis. Mitochondrial dysfunction has been implicated as a key pathophysiological factor in Type 2 Diabetes Mellitus (T2DM), contributing to insulin resistance, metabolic inflexibility, and beta-cell dysfunction. This review explores the intricate mechanisms underlying mitochondrial impairments in T2DM, including defective oxidative phosphorylation, disrupted mitochondrial dynamics, impaired mitophagy, and excessive reactive oxygen species (ROS) generation, with a focus on potential therapeutic interventions targeting mitochondrial pathways.
Mechanistic Insights into Mitochondrial Dysfunction in T2DM
1. Defective Oxidative Phosphorylation and ATP Synthesis
Mitochondrial oxidative phosphorylation (OXPHOS) occurs through the electron transport chain (ETC), comprising Complexes I-IV and ATP synthase (Complex V). In T2DM, evidence suggests a downregulation of mitochondrial ETC activity, particularly in Complex I (NADH:ubiquinone oxidoreductase) and Complex III (cytochrome bc1 complex), leading to reduced ATP synthesis. This dysfunction is often linked to compromised NADH oxidation and inefficient proton gradient formation, resulting in cellular energy deficits and impaired insulin-stimulated glucose uptake.
2. Elevated Reactive Oxygen Species (ROS) and Oxidative Stress
Mitochondria are a primary source of ROS, predominantly generated at Complex I and Complex III during electron leakage. In T2DM, excess substrate influx due to hyperglycemia leads to mitochondrial overactivation, driving excessive ROS production. Elevated ROS induces oxidative damage to mitochondrial DNA (mtDNA), lipids, and proteins, disrupting mitochondrial integrity and function. Oxidative stress further impairs insulin signaling by activating stress-responsive kinases such as c-Jun N-terminal kinase (JNK) and IκB kinase (IKK), contributing to systemic insulin resistance.
3. Mitochondrial Biogenesis and Transcriptional Dysregulation
Mitochondrial biogenesis is regulated by the transcriptional coactivator Peroxisome proliferator-activated receptor-gamma coactivator-1 alpha (PGC-1α), which modulates downstream transcription factors such as Nuclear Respiratory Factors (NRF-1/NRF-2) and Mitochondrial Transcription Factor A (TFAM). In T2DM, PGC-1α expression is downregulated, impairing mitochondrial biogenesis and reducing mitochondrial density, leading to decreased oxidative capacity in metabolically active tissues like skeletal muscle and liver.
4. Disrupted Mitochondrial Dynamics and Mitophagy
Mitochondrial quality control is maintained through dynamic fission and fusion processes. Fission, mediated by Dynamin-related protein 1 (Drp1), is necessary for mitochondrial fragmentation and mitophagy, while fusion, regulated by Mitofusin 1/2 (Mfn1/2) and Optic Atrophy 1 (OPA1), maintains mitochondrial integrity. In T2DM, an imbalance favoring excessive fission leads to mitochondrial fragmentation, impairing energy metabolism and exacerbating insulin resistance. Moreover, defective mitophagy, regulated by PTEN-induced kinase 1 (PINK1) and Parkin, results in the accumulation of dysfunctional mitochondria, further aggravating metabolic dysfunction.
Implications of Mitochondrial Dysfunction in T2DM Pathophysiology
1. Skeletal Muscle Insulin Resistance
Skeletal muscle accounts for ~80% of postprandial glucose uptake, relying on mitochondrial ATP production for insulin-mediated glucose transport. Impaired mitochondrial function in muscle cells reduces oxidative phosphorylation efficiency, promoting a shift towards glycolysis and lipid accumulation, ultimately leading to insulin resistance.
2. Pancreatic Beta-Cell Dysfunction
Mitochondrial ATP production is essential for insulin secretion in pancreatic beta cells. ATP-sensitive potassium channels (K_ATP) regulate glucose-stimulated insulin secretion (GSIS), with ATP/ADP ratios dictating channel closure and depolarization-induced insulin exocytosis. In T2DM, mitochondrial dysfunction leads to inadequate ATP generation, impairing GSIS and reducing insulin secretion capacity. Additionally, oxidative stress-induced beta-cell apoptosis contributes to progressive loss of beta-cell mass.
3. Hepatic Mitochondrial Dysfunction and Lipid Dysregulation
Mitochondrial dysfunction in hepatocytes contributes to hepatic insulin resistance and non-alcoholic fatty liver disease (NAFLD). Impaired fatty acid oxidation due to dysfunctional mitochondria leads to lipid accumulation, exacerbating hepatic insulin resistance and systemic metabolic dysregulation.
Therapeutic Strategies Targeting Mitochondrial Dysfunction
1. Exercise-Induced Mitochondrial Adaptation
Physical activity upregulates PGC-1α expression, enhancing mitochondrial biogenesis and oxidative metabolism. High-intensity interval training (HIIT) and endurance exercise improve mitochondrial efficiency and reduce oxidative stress, mitigating insulin resistance in T2DM patients.
2. Pharmacological Modulation of Mitochondrial Function
Metformin: Enhances mitochondrial complex I activity, reducing hepatic gluconeogenesis and oxidative stress.
Thiazolidinediones (TZDs): Activate PPAR-γ, promoting mitochondrial biogenesis and improving insulin sensitivity.
Mitochondria-targeted Antioxidants: Agents like MitoQ, SkQ1, and SS-31 reduce mitochondrial ROS, preventing oxidative damage and preserving mitochondrial function.
3. Nutritional and Metabolic Interventions
Ketogenic and Low-Carb Diets: Enhance mitochondrial fatty acid oxidation, reducing lipid accumulation and improving metabolic flexibility.
Intermittent Fasting: Induces mitochondrial biogenesis and autophagy, improving metabolic homeostasis.
Nutraceuticals: Coenzyme Q10, resveratrol, and nicotinamide riboside (NR) enhance mitochondrial function and energy metabolism.
4. Emerging Gene and Cellular Therapies
Gene Therapy: Targeted upregulation of PGC-1α and TFAM to restore mitochondrial function.
Mitochondrial Transplantation: Direct transfer of healthy mitochondria to replace dysfunctional ones, an emerging frontier in metabolic disease management.
Conclusion
Mitochondrial dysfunction is a central determinant in the pathogenesis of T2DM, affecting insulin signaling, glucose metabolism, and lipid homeostasis. Targeting mitochondrial pathways through exercise, pharmacological agents, dietary modifications, and emerging gene therapies offers promising avenues for improving metabolic health in T2DM.

WoLF PSORT is an extension of the PSORT II program for protein subcellular localization prediction, which is based on the PSORT principle. WoLF PSORT converts a protein's amino acid sequences into numerical localization features; based on sorting signals, amino acid composition and functional motifs. After conversion, a simple k-nearest neighbor classifier is used for prediction. To predict the subcellular localization of your target protein, simply paste your protein's amino acid sequence (single letter code) in the WoLF PSORT window below and click submit.
DeepLoc - 2.0
Prediction of eukaryotic protein subcellular localization using deep learning. DeepLoc 2.0 predicts the subcellular localization(s) of eukaryotic proteins. DeepLoc 2.0 is a multi-label predictor, which means that is able to predict one or more localizations for any given protein. It can differentiate between 10 different localizations: Nucleus, Cytoplasm, Extracellular, Mitochondrion, Cell membrane, Endoplasmic reticulum, Chloroplast, Golgi apparatus, Lysosome/Vacuole and Peroxisome. Additionally, DeepLoc 2.0 can predict the presence of the sorting signal(s) that had an influence on the prediction of the subcellular localization(s).
MembraneFold
About MembraneFold
MembraneFold combines two types of protein sequence prediction tools: protein structure (AlphaFold [1] and OmegaFold [2] and transmembrane protein topology (DeepTMHMM [3]. The Mol* toolkit [4] is used for visualisation.
The purpose of MembraneFold is to present membrane positioning and structure predictions of a given protein chain simultaneously. The tool allows to obtain a fast overview of this information and quickly toggle between the topology annotation and the structure confidence scores.
sorry it took me so long to get to this ask!
this is really neat, and i think its great to see more tools predicting what happens to certain structures. i did consider looking for localization signals in the proteins i am making for this blog, but ultimately decided against it to keep things easier for me. furthermore, i honestly don't entirely trust most of these to even make it through the translation step, and i shudder to think what a mess any sort of co-localization would make on top of the existing horror of my abominations. to be honest i'm also just not sure how to use these and don't really want to download any more software, at least not until i have more free time. however, its still really fun to mess around with tools like this, and i highly encourage anyone interested to look into it!

Acute kidney injury following exposure to a formaldehyde –free hair straightening products by Dr. Nabil Abu-Amer in Journal of Clinical Case Reports Medical Images and Health Sciences
ABSTRACT
Formaldehyde- free hair straightening products are hair smoothening solutions widely used by professional beauty salons. Formaldehyde-free hair straighteners do not technically contain formaldehyde, however they contain other chemicals such as glyoxyloyl carbocysteine which releases formaldehyde upon contact with heat. Moreover, its by-product glyoxylate may convert to oxalate, both compounds have potential nephrotoxic effect.
Case presentation: 41-year-old woman presented to the emergency room with weakness, nausea , vomiting and stage three acute kidney injury according to Kidney Disease: Improving Global Outcomes acute kidney injury staging (KDIGO) shortly after exposure to formaldehyde - free hair straightening product, other causes of acute kidney injury were excluded such as preceding acute illness, drug history or others nephrotoxic agent exposure On physical examination the patient was pale, her vital signs were normal. The urine microscopy and serologic workup was not indicative. Kidney core biopsy reveal interstitial edema, acute interstitial nephritis and oxalate crystal nephropathy. Kidney function completely recovered after a short course of steroid therapy.
Conclusions: We present a case of severe kidney injury after exposure to hair straightening products branded as formaldehyde free but actually contain other chemicals products which release formaldehyde and other toxic chemicals when heated during the straightening procedure and may cause systemic toxicity, particularly kidney injury. Different cosmetic products are widely in use, not all are under a tight regulation, and therefore it is important to raise the awareness of both medical teams and consumers of possible adverse health effects of different cosmetic products.
INTRODUCTION
Nephrotoxicity is defined as kidney injury due to toxic effects of chemicals. There are various forms of chemicals and drugs that may affect renal function in various mechanism including acute tubular necrosis (ATN), tubulopathy and electrolyte imbalance, acute interstitial nephritis (AIN), glomerular damage, crystal nephropathy, and thrombotic microangiopathy [1-3].
Formaldehyde- free hair straightening products contain potentially toxic chemicals other than formaldehyde. One potential such substance is glyoxyloyl carbocysteine, which is composed of glyoxylic acid, cysteine and acetic acid. Glyoxylic acid both releases formaldehyde when heated and is converted into either glycine by AGT1 (alanine:glyoxylate aminotransferase 1) or oxalate by glycolate oxidase in the human cell peroxisomes [4].
Formaldehyde is a colorless aldehyde poisonous gas at room temperature [5]. It is usually mixed with water and when the small fraction of soluble formaldehyde reacts with water, it quickly forms methylene glycol. For every molecule of free formaldehyde, 1,820 molecules of methylene glycol are formed [6]. Methylene glycol reverts back to free formaldehyde almost immediately upon contact with air or skin. Formaldehyde is thus absorbed through skin, eyes, and inhalation, and is eliminated through the urine [7-8]. During the hair straightening process, high levels of formaldehyde are found in samples of air taken from beauty salons [9] and in specimens of hairstylist workers skin [10-11].
In the kidney, formaldehyde has been reported to cause direct cytotoxic effect resulting in acute toxic tubular necrosis [12-13], and may also cause an immune system response leading to acute interstitial nephritis.
Another potential nephrotoxic component of hair straightening products is oxalate, which is an end product of glyoxylic acid. Increased levels of oxalate promote calcium oxalate precipitation in various tissues including the kidneys, resulting in toxic injury.
Case presentation
A 41-year-old woman with a history of hypothyroidism and sleeve gastrectomy five years ago, presented to the emergency department with profound weakness, nausea and vomiting. Her symptoms began three days earlier, immediately after using a professional hair straightening formaldehyde- free product in a professional beauty salon.
On physical examination the patient was pale, her vital signs were normal, heart rate was 66 bpm, blood pressure was 125/70 mmHg, she had no fever or respiratory distress and appeared euvolemic.
Laboratory investigations revealed a serum creatinine of 3.46 mg/dl (one year prior to the event Cr. value was 0.6 mg/dl), urea 77 mg/dl, and electrolytes, liver function tests, Beta human chorionic gonadotropin (β-hCG) and complete blood count were normal. Blood venous gases revealed: pH 7.375, HCO3 21 mmol/L and base excess 3 mmol. The anion gap and serum osmolar gap were normal. Urinalysis demonstrated leukocyturia +1 without hematuria or proteinuria.
During hospitalization urine output was normal, repeat urinalysis demonstrated leukocyturia +1 without hematuria or proteinuria, and Bence-Jones protein was negative. Urine microscopy demonstrated epithelial cells with few white blood cells without any casts or crystals. Renal ultrasound showed 14.4 cm bilateral echogenic, edematous renal parenchyma (shown in Fig. 1).
A full serologic workup including hepatitis B and C, Human immunodeficiency virus (HIV), syphilis, antinuclear antibody (ANA) , Anti-double stranded DNA, Antineutrophil cytoplasmic antibody (ANCA), Anti-Phospolipid antibody (APLA) was normal except for a complement C3 level of 80 mg/dl (normal range 90-110 mg/dl).
On the 4th hospitalization day a renal core biopsy was performed. The histologic examination (shown in Fig. 2) was correlatd with acute tubular necrosis, tubulo- intersitial nephritis and oxalate crystals . With the diagnosis of interstitial nephritis, the patient was started on prednisolone 1 mg/kg, one week later serum creatinine decreased to a level of 0.98 mg/dl.
A: Glomeruli were normo-cellular and without signs of active glomerular disease (arrow heads), tubules showed signs of diffuse tubular injury (black arrow) and tubules contained oxalate crystals (blue arrow). B:The interstitium showed edema associated with multifocal mixed inflammatory infiltration with multiple eosinophils and foci of tubulitis. C:There was one epithelioid granuloma. D:Tubules contained oxalate crystals (blue arrow) observed under polarized light-microscopy. Immunofluorescence analysis revealed C3 1+ in blood vessel walls only.
Discussion
This patient presents an unusual case of kidney toxic and inflammatory injury accompanied with oxalate deposition secondary to hair straightening product. In a literature review, only few cases [14-15] of acute kidney injury (AKI) following hair straightening formaldehyde- free product exposure were reported. All cases were reported after 2019. The spectrum of kidney injury following hair straightening ranges from mild to severe kidney injury requiring renal replacement therapy. The histopathologic changes reported mainly depicted severe acute tubular necrosis and acute interstitial nephritis.
Our patient presented with stage 3 AKI following hair straightening formaldehyde - free product exposure. Other causes of AKI were excluded such as preceding acute illness, drug history or other nephrotoxic agent exposure. Laboratory workup revealed leukocyturia +1, and ultrasonography was significant for enlarged edematous echogenic renal parenchyma. Kidney biopsy demonstrated acute interstitial nephritis, oxalate crystal precipitation and acute tubular necrosis. We speculate that the clinical presentation and the histopathologic changes directly resulted from exposure to the hair straightening formaldehyde- free product.
In reviewing the ingredients of the specific product used in this case, it included glyoxyloyl carbocysteine, glyoxyloyl keratin amino acid, propylene glycol glycerin, phenoxyethanol, ethylhexylglycerin disodium and other collagen, surfactant and fragrance components. We did not find evidence in the medical, pharmacological and chemical literature that any of these substances causes acute kidney injury other than glyoxyloyl carbocysteine.
Many hair straightening products are labeled as formaldehyde "free" but actually contain chemicals such as glyoxyloyl carbocysteine or methylene glycol which release formaldehyde and other toxic chemicals when heated, e.g the carbocysteine hair treatment represents the combination of glyoxylic acid + cisteine + acetic acid. Glyoxylic acid contains an aldehyde functional group, glyoxylic acid behaves as an aldehyde by heating during the hair straightening process thus releasing high levels of formaldehyde gas exceeding the capacity of exposure[16]. On top of that, glyoxylic acid absorbed through the scalp may had converted to oxalic acid [17] which may precipitate in kidney tissue. It is possible that other components such as propylene glycol may cause osmotic renal injury. In this case, serum osmotic gap was not available since it calculated four days after exposure.
Conclusion
In conclusion, a case of severe kidney injury after exposure to hair straightening products branded as formaldehyde free is presented. This case highlights the sensitivity of the kidney to various environmental and commercial products, some of which have not been fully characterized or identified yet.
It is important to raise the awareness of both medical teams and consumers, of possible adverse health effects of different cosmetic products, including acute kidney injury, and perhaps promote tighter regulation of such products.

In my senior year of highschool we had a final project in AP Biology which was open-ended and could be just about anything. I rewrote (and performed) Thrift Shop to be about various branches of biology using the terminology that we had used that year. I titled it "Niche Shop."
These are the lyrics.

Hey, so I read your ask on that other blog about adiponectin and how it basically converts fat from visceral to subcutaneous. Do you know if there's any supplements or medicaments one could take to increase adiponectin levels? purely hypothetically, of course.
Yes, MCT oil boosts adiponectin levels. See these studies for more info:
Lower weight gain and higher expression and blood levels of adiponectin in rats fed medium-chain TAG compared with long-chain TAG
Medium Chain Fatty Acids Are Selective Peroxisome Proliferator Activated Receptor (PPAR) γ Activators and Pan-PPAR Partial Agonists
Genetic modulation of PPARgamma phosphorylation regulates insulin sensitivity

I'm drawing a cell diagram so I have my own image to use for presentations and stuff. but I'm having trouble picking colours for all the organelles. so I would like to task you - mutuals, followers, maybe even mutuals in law if someone decides to reblog this.. anyone who sees this - with suggesting colours for the organelles I have left!
here's what I have currently:

[id: an in-progress drawing of a cell with pale periwinkle cytoplasm, a pink rough endoplasmic reticulum with red ribosomes, a light yellow nucleus with blue-green nucleolus, and a few orange mitochondria. /end id]
the organelles that I need colours for are:
1. smooth endoplasmic reticulum (like rough ER but no dots - should I make it same colour??)
2. lysosome (small orb)
3. peroxisome (medium orb)
4. Golgi apparatus (silly looking blob guys)
5. vacuole (lone blobs)
6. centrosome (orb with tiny orbs)
if your favourite organelle isn't here feel free to suggest it with a colour and maybe I'll add it!
