2020/11/11 Daily Notes

 "The modern cognitive embodied theory demonstrates that our mental and cognitive processes are embodied in our bodies, depending on our bodies’ specific activity patterns44. This means that, cognition is not independent of body movement, but is deeply rooted in the human body and the interaction between the body and our world."

Nocturia, Aquaporins, and Oxytocin

[2020-7-13] Someone posted about nocturia on HealthUnlocked's Parkinson's Movement forum and I replied with the  following (I don't think I can keep up with doing the reference properly, perhaps if it starts to really bother me I will edit): Apart from prostate and autonomic nervous system problems, one issue in aging related to nocturia might be loss of function of aquaporins. Aquaporins are membrane channels for water; though water can diffuse across cell membranes AQPs move water faster and are particularly important under stress conditions. AQP function declines with age and could contribute to many age-related health issues including reduction in blood brain barrier function. hindawi.com/journals/omcl/2... ncbi.nlm.nih.gov/pmc/articl... Oxytocin has some vassopressin-like activity and helps move AQP from inside the cell to the membrane surface when needed. jasn.asnjournals.org/conten... Oxytocin levels decline with age: ncbi.nlm.nih.gov/pmc/articl... The probiot...

Directory of STEM & Mastodon Instances

I've started a directory of STEM [science, technology, engineering and mathematics] and medical mastodon instances - mainly English language. Here's the link to the Google spreadsheet: https://docs.google.com/spreadsheets/d/1hZz1FB2HP-nqXNHigaiExFWvWTkMJ-TwYJa8W3Pdh-Q/edit?usp=sharing If you want to add to the form either request permission to edit through the form or you can message me: http://zeroes.ca/@Rhyothemis   I also have a list of Mastodon / FediVerse STEM and medical hashtags: https://docs.google.com/spreadsheets/d/1Alc8MlwDCziS6Z-CFij5A6A1MKQtGYTeO--xfW1vl6A/edit?usp=sharing    It's a shame what's happened with Twitter - it was great tool for rapid science communication and SciComm in general. I'm hoping more researchers find a new home in the FediVerse and make liberal use of hashtags so as to avoid siloing of information.

collagen peptides, prolyl-hydroxyproline, aspartate transaminase (AST) - brief notes

Marine collagen peptides have antioxidant properties.  Characterization and Antioxidant Activity of Collagen, Gelatin, and the Derived Peptides from Yellowfin Tuna (Thunnus albacares) Skin [2020] - https://pubmed.ncbi.nlm.nih.gov/32023998/  Functional and bioactive properties of collagen and gelatin from alternative sources: A review [2011] - https://www.sciencedirect.com/science/article/pii/S0268005X11000427 "The exact mechanism underlying the antioxidant activity of peptides is not fully understood, but various studies have shown that they are lipid peroxidation inhibitors, free radical scavengers and transition metal ion chelators. According to some studies, gelatin peptides could inhibit lipid peroxidation more efficiently than antioxidative peptides derived from many other protein sources ...   .. peptides isolated from hoki skin gelatin were capable of enhancing the expression of antioxidative enzymes such as glutathione peroxidase, catalase and superoxide...

cold exposure & breast cancer

A recent flare up of fibrocystic breast symptoms had me wondering if use of cold packs has any effect on breast cancer (BC) risk. Cold packs are often recommended for mastalgia (breast pain) from fibrocystic breast disease, mastitis, engorgement due to breast feeding cessation, and post breast cancer surgery. Whole body cold exposure has been found to increase tumor growth and metastasis in mice: https://www.medicalnewstoday.com/articles/269266 T-cell function is diminished at colder temperature leading to reduced anti-tumor immune responses. The article notes implications for standard research practice of housing mice at relatively colder temperatures - another thing to add to the list of problems in current practices.  (Could cold acclimation be used to promote tolerance in autoimmunity and atopy? Another topic for another day.) The mice were subjected to whole body cold exposure  - not spot treatment. It is conceivable that reducing acute inflammation through localized cold...
