#2747 - Sargassum sinclairii
Described by Sir Joseph Dalton Hooker in 1845, in his Algae Novae Zelandiae; being a catalogue of all of the species of algae yet recorded as inhabiting the shores of New Zealand, with characters and brief descriptions of the new species discovered during the voyage of H.M. discovery ships "Erebus" and "Terror" and of others communicated to Sir W. Hooker by Dr. Sinclair, the Rev. Colenso, and M. Raoul. London Journal of Botany 4: 521-551. He named this one after Dr Andrew Sinclair (1794–1861), a surgeon, collector, and second Colonial Secretary to New Zealand. 15 other plants are named after him as well.
The most common Sargassum species in Aotearoa, and apparently more rarely recorded along the eastern coast of Australia.
Most brown macroalgae prefer cooler waters, but many Sargassum species live in temperate and tropical oceans. A few species are pelagic - floating in the open ocean for their entire lives. The Sargasso Sea in the Atlantic is named after the large quantities of the seaweed drifting on the surface. A good number of species including the Gulfweed Crab Planes minutus and the Sargassum Anglerfish Histrio histrio have evolved to live in the floating forests.
In the last decade or so, populations of the floating seaweed have exploded, inundating the beachs of several Caribbean islands up to a meter deep. This seems to be related to fertilizer runoff from the Amazon basin.

PUBLISHED SCIENTIFIC PAPER: “Comparative diversity analysis and species composition of seagrass and macroalgae along the intertidal zone of Sarangani Province, Philippines”
(Published in the Journal of Biodiversity and Environmental Sciences (JBES) Volume 5, No. 4, p. 356-364, 2014. Published with Alima, et al.)

ABSTRACT. The study was carried out as an intensive sampling survey in the intertidal zones of Sarangani Province (Glan and Maasim), relying on the low tide to determine the total species number, relative species abundances, frequency and spatial distribution of seagrass. Eight Species of seagrasses and nineteen species of macroalgae were gathered. These have been the sampling sites of researchers, most especially students, for its reputation of having diverse distribution of such aquatic plants. A total of fifty sampling plots were laid using quadrats; ten quadrats were arranged alternately with a five-meter disparity between each plot, placed perpendicularly to the shore. The study identified species of seagrass belonging to the family Potamogetonaceae and Hydrocharitaceae. Nineteen species of macroalgae were identified from where either seagrass was present or absent and categorized under the family of Dasycladaceae, Ulvaceae, Halimedaceae, Caulerpaceae, Dictyotaceae, Sargassaceae, Galaxauraceae, Wurdemanniaceae, Gelidiaceae, Gracilariaceae and Cryptonemiaceae.Seagrass. Biodiversity indices such as dominance, Shannon’s diversity, evenness, species richness and number of individuals were also determined using PAST software. Distribution analysis revealed the three highest number of species among the eightseagrass species were Enhalusacoroides, Haloduleuninervis and Thalassiahemprichii-such werec ommon in both sites. The Padina minor from the nineteen identified macroalgaespeciesin the algal community has the most number of species. There are great indications of seagrass and macroalgae presence with its distribution when proper sampling procedure is done. Researchers strongly recommend that physicochemical such salinity and sedimentation and also correlation on distribution of species be studied further.

In vitro CYTOTOXIC POTENTIAL OF TURBINARIA CONOIDES AND SARGASSUM PLAGIOPHYLLUM EXTRACT UPON BJ CELL LINE | UTTAR PRADESH JOURNAL OF ZOOLOGY
Complex polysaccharides and sterols are formed by marine algae, and they have incredible therapeutic properties. Secondary metabolites are biologically active molecules rich in carbon sources that are known for biological activity such as anti-coagulant, anti-inflammatory, anti-bacterial, anti-tumor, and cytotoxic effects on certain cell lines. Turbinaria, a marine brown algae belonging to the Sargassaceae family, is inedible and contains oxygenated sterols, which have cytotoxic properties. Brown algae extracts from Turbinaria conoides and Sargassum plagiophyllum showed cell viability in BJ cells at various concentrations. Unlike the other solvent extracts of ethyl acetate and methanol, T. conoides hexane extract showed no toxicity in the range of 3.5 to 500 g/ml on BJ cells. The aim of this study is to determine the cytotoxic activity of three different solvent extracts against the BJ cell line (Human foreskin fibroblast cells) (Hexane, Methanol, Ethyl acetate).

Fucoidan from marine brown algae attenuates pancreatic cancer progression by regulating p53-NFκB crosstalk.
PMID: Phytochemistry. 2019 Aug 23 ;167:112078. Epub 2019 Aug 23. PMID: 31450091 Abstract Title: Fucoidan from marine brown algae attenuates pancreatic cancer progression by regulating p53 - NFκB crosstalk. Abstract: Poor pancreatic cancer (PC) prognosis has been attributed to its resistance to apoptosis and propensity for early systemic dissemination. Existing therapeutic strategies are often circumvented by the molecular crosstalk between cell-signalling pathways. p53 is mutated in more than 50% of PC and NFκB is constitutively activated in therapy-resistant residual disease; these mutations and activations account for the avoidance of cell death and metastasis. Recently, we demonstrated the anti-PC potential of fucoidan extract from marine brown alga, Turbinaria conoides (J. Agardh) Kützing (Sargassaceae). In this study, we aimed to characterize the active fractions of fucoidan extract to identify their select anti-PC efficacy, and to define the mechanism(s) involved. Five fractions of fucoidan isolated by ion exchange chromatography were tested for their potential in genetically diverse humanPC cell lines. All fractions exerted significant dose-dependent and time-dependent regulation of cell survival. Fucoidans induced apoptosis, activated caspase -3, -8 and -9, and cleaved Poly ADP ribose polymerase (PARP). Pathway-specific transcriptional analysis recognized inhibition of 57 and 38 nuclear factor κB (NFκB) pathway molecules with fucoidan-F5 in MiaPaCa-2 and Panc-1 cells, respectively. In addition, fucoidan-F5 inhibited both the constitutive and Tumor necrosis factor-α (TNFα)-mediated NFκB DNA-binding activity in PC cells. Upregulation of cytoplasmic IκB levels and significant reduction of NFκB-dependent luciferase activity further substantiate the inhibitory potential of seaweed fucoidans on NFκB. Moreover, fucoidan(s) treatment increased cellular p53 in PC cells and reverted NFκB forced-expression-related p53 reduction. The results suggest that fucoidan regulates PC progression and that fucoidans may target p53-NFκB crosstalk and dictate apoptosis in PC cells.

Innisfree Seaweed Soothing Mask Sheet Moist Soothing Sargassaceae Review:
Lately I have been using a lot of masks made out of seaweed, since it’s a fashion currently in Korea. I must say beforehand this mask has nothing to do with the Mamonde Seaweed Dustcut mask! I mean, maybe a little, after all it’s seaweed, but there are other masks this is more similar to. Seaweed should be good for the…

sargassaceae replied to your post: hmmmm HMM legit AAC device...
if you don’t mind me asking, why is it that tablet pc + portable speaker setup turned out to not be a good solution?
hmm, it could be? i haven't ignored your (or anyone's) advice, but i don't want my parents to know about this (they would freak) and i don't have the money myself yet anyhow, so right now i'm just... fucking around on the internet looking for options. my speech isn't TOO awful currently, though it takes scary dips now and then, and i'll be transferring somewhere else/moving out either next semester or the one after that. i hope.
also if it were a tablet i dislike those touchscreens and would probably have to get a regular keyboard to go along with it which would render the entire setup bulky
wow that was more information than anyone needed the answer is i am a doofus
