  Vidcast:  https://youtu.be/RtDaP6MJ-xU Shells that engulf influenza viruses preventing their infectivity may someday prevent the seasonal flu without vaccines.  German researchers report successful use of this strategy in pre-clinical trials.   The researchers take phages, viruses that ordinarily attack bacteria, and empty out their genetic material.  They adapt these empty nanoshells for attachment to flu virus like Velcro® thereby preventing the virus from attacking human respiratory cells.  The non-infective phage nanoshell may also trigger a more vigorous immune elimination response against the inactivated flu viruses.   This approach isn’t ready for prime time yet, but it may also prove useful for controlling coronaviruses including our current CoVid19.  Let’s hope we don;’t have to wait till 2525.   https://www.nature.com/articles/s41565-020-0660-2   #phage #influenza #coronavirus #nanotechnology

Legend has it that her locks whitened overnight before her trip to the guillotine.   Extreme stress ramps up the sympathetic nervous system for a danger response.  The neurotransmitter norepinephrine gushes from nerve endings throughout the body including around our hair follicles.  The excess nor-ep recruits stem cells that ordinarily would become pigment producing factories.  They don’t, no pigment, no hair color.   https://www.ncbi.nlm.nih.gov/pubmed/31969699   #stress #coronavirus #grayhair #norepinephrine

  Vidcast: https://youtu.be/APXe9NaJ-B8   Those with O positive blood are 20% less likely to test positive for the coronavirus and AB blood 44% less likely.  Those with A positive blood are 38% more likely to be positive.  The Biomedical Informatics unit at Columbia has just pre-published this data after their analysis of over 1500 patients seen at two New York City hospitals.   Various blood groups only only had statistical associations with viral positivity and not with disease severity, need for intubation, or risk of death from CoVid19 disease.   These findings are generally consistent with those I reported from Chinese studies.  The exception: Chinese with the rare AB blood had a greater risk of CoVid positivity.     https://www.medrxiv.org/content/10.1101/2020.04.08.20058073v1.full.pdf   #covid19 #coronavirus #abogroup #bloodgroup  

  Vidcast:  https://youtu.be/J0XoqkE547U   ACE inhibitors and Angiotensin Receptor Blocking medications appear to help hypertensive patients fightCoVid19 infections.  Chinese investigators now report a series of 564 hospitalized CoVid19 patients and British researchers a series of 205.   Those Chinese on the angiotensin-related medications were 5 times less likely to develop a severe case of pneumonia. The Brits on ACE inhibitors were half as likely to require critical care support or to die of their CoVid disease.   The investigators conclude that those hypertensive patients with CoVid19 infections should not be switched off angiotensin drugs.  On the other hand, they stop short of recommending their use as therapeutic agents for infected patients with treatable high blood pressure.   https://www.medrxiv.org/content/10.1101/2020.04.08.20057539v1   https://www.medrxiv.org/content/10.1101/2020.04.07.20056788v1.full.pdf   #covid19 #coronavirus #hypertension #angiotensin #aceinhibitor #angiotensinreceptorblocke

  Vidcast:  https://youtu.be/O52Z-1S5OUg   CoVid19 aerosols from an unknowingly infected neighbor can easily infect you as you shop or walk.  Finnish researchers, studying the production and spread of virus-laden microdroplets, show that a single cough generates a cloud of virus aerosol that can waft for minutes over several aisles in a grocery store.  The cough also sprinkles nearly shelves and the floor with live virus.   In other reports, I’ve told you that simple cotton masks or even surgical masks do not block virus from an infected person.   Distance as far as you can, and use a multilayered mask.  When the PPE supply for first responders eventually improves, go for N95 or KN95 masks.   https://www.aalto.fi/en/news/researchers-modelling-the-spread-of-the-coronavirus-emphasise-the-importance-of-avoiding-busy   #covid19 #coronavirus #aerosol #mask

  Vidcast:   https://youtu.be/H1zXuFDjnOY   Allergy sufferers!  Coating nasal linings with a gel could reduce your seasonal misery without using stronger drugs.  German researchers report this finding after studying 18 adults with known allergies.   The subjects were randomized to receive either gel or no treatment during 4 hour sessions in a pollen chamber.  Nasal gel significantly squelched allergic nasal congestion and postnasal drip.   The study used Nascum-Plus, an oil-based solution with bio-adhesive properties, that’s not available in the US.  Saline nasal gels by NeilMed, Ayr, and NasalGuard ARE available online.  The effects may be less dramatic and the spray will require re-application, but nasal saline gel could reduce your symptoms and medication needs.   https://www.karger.com/Article/Abstract/506129   #allergy #pollen #allergicrhinitis #nasalgel
