Vitamin D RDA Too Low, by Ten Fold
A calculation error may have skewed the vitamin D recommendations by the National Academy of Sciences (NAS), Institute of Medicine (IOM). They are far too low, by a factor of ten, say researchers at UC San Diego and Creighton University. Researchers submitted a letter of challenge, published in the journalRead
Lomatium Dissectum Inhibits CXCL10, Linked to Influenza A
The Journal for Restorative Medicine shows that Lomatium dissectum may provide an option to for integrative care specialists for influenza A. The plant is native to the Western US and is traditionally used in the Native American culture to treat influenza. During the 1918 flu epidemic, it was reported thatRead
Shorter Flu Duration with Lianhuaqingwen
Rapid antigenic evolution in an influenza virus increases the likelihood of emergence of novel strains. Under the circumstances, if vaccines are not yet available, treatment plays a crucial role in control of the disease. In this meta-analysis, the authors have compared the efficacy and safety of Lianhuaqingwen capsule (LHQW-C) and oseltamivir in treating influenza A virus infection.

Larch Arabinogalactan and Immune Response
In 2013, a study, Immunomodulatory Effects of ResistAid™: A Randomized, Double-Blind, Placebo-Controlled, Multidose Study, evaluated the ability of a proprietary arabinogalactan extract from the larch tree (ResistAid™, Lonza Ltd., Basel, Switzerland) to change the immune response in healthy adults to a standardized antigenic challenge of tetanus and influenza vaccines in a dose-dependent manner compared to placebo. As it is flu season, Today’s Practitioner is revisiting the study and the subject with an interview with Bryan Rodriguez, Global Products Manager, of Lonza, makers of Resist Aid. Download the full study at the end of this article.

Influenza Vaccine in Elderly: Nutritional Status-Dependent Immunogenicity
The immune response to influenza vaccine is attenuated in elderly persons, though they are at greatest risk for morbidity and mortality by influenza virus infection. Experimental studies demonstrate that co-administration of L-cystine and L-theanine enhanced antigen-specific production of immunoglobulin in aged mice infected with influenza virus. This study thus investigated the effect of L-cystine and L-theanine on antibody induction by influenza vaccines in elderly persons.

Attenuation of Natural Killer T-Cells with Cystine and Theanine
Men who perform resistance training 3 times a week for at least 6 months tend to have lower T-helper cell counts than non–resistance trained men. In addition, the natural killer (NK) cell count, an index of innate immunity, has been shown to decrease below the resting value after submaximal resistance exercise in both resistance-trained and non–resistance-trained men. It is a common hypothesis that resistance training impairs the immune system rather than enhancing its functions. This study examined the affects of cystine and theanine on NK cells, inflammation and immunity.

Double-blind, Randomized Trial on Cystine, Theanine and the Common Cold
The common cold, an acute infection properly known as “cold syndrome,” is the most common human illness. The majority of cases of cold syndrome are acute infections of the upper respiratory tract, and its major cause is viral infection. Conventional methods of treatment use medications, such as analgesic agents and antihistamines, but these are only effective for the alleviation of symptoms, such as sneezing and runny nose. The incidence of subjects with colds during this trial was significantly lower in the CT group than in the placebo group, although the duration of the colds was not significantly different between the groups. These results suggest that CT supplementation may be useful for the prevention of the common cold.

NEW RESEARCH: Enzyme cIAP2 Gatekeeper of Cell Death in Influenza
NEWS McGill researchers, led by Dr. Maya Saleh of the Department of Medicine, have identified an enzyme, cIAP2 that helps the lungs protect themselves from the flu by giving them the ability to resist tissue damage. “It’s a discovery that offers exciting new avenues for controlling influenza, since untilRead
