A study published April 2009 in the Archives of Neurology found that older patients taking aspirin appeared more likely to have barely-perceptible bouts of cerebral “microbleeding,” detected by researchers with the aid of magnetic resonance imaging (MRI) technology.

Children Who Get Flu Vaccine Have Three Times Risk Of Hospitalization For Flu, Study Suggests
ScienceDaily (2009-05-20) — The inactivated flu vaccine does not appear to be effective in preventing influenza-related hospitalizations in children, especially the ones with asthma. In fact, children who get the flu vaccine are more at risk for hospitalization than their peers who do not get the vaccine, according to new research. While these findings do raise questions about the efficacy of the vaccine, they do not in fact implicate it as a cause of hospitalizations, according to researchers.

Flu Vaccination in Asthmatics: Does It Work?

Interesting and timely post on Wired Science yesterday. Virii have been found to remain virulent for centuries, and could potentially for millenium, in the frozen lakes of Siberia. This is likely due to the configuration or “anatomy” of a virus particle. You can read more of the report about a presentation made at the American Society for Microbiology meeting in Philadelphia.
The June 2009 issue of Pharmacology Biochemistry and Behavior includes a study looking at a link between melanin production as a result of UV exposure and tobacco use in African Americans. Although the findings established a correlation, repeated studies are needed to verify their results. They go on to hypothesize that this correlation may be responsible for the stronger addiction to tobacco use that has been previously noted in darker skinned individuals. From the abstract;
Link between facultative melanin and tobacco use among African Americans

“The results of this analysis support the hypothesis of a positive association between melanin levels and tobacco use, dependence, and exposure among African American smokers.”

The journal ‘Immunity‘ yesterday released a study showing strong evidence, and confirming a previous controversial study, that between initial and subsequent infection 80% of CD4 memory T-lymphocytes are located within bone marrow and not the circulatory system as has been widely believed by heath researchers.

The “Scientist” magazine blog posted a follow up on a report last week of a division of a ‘fake journal’. Yesterday a follow up post was made stating that the reported journal was not the only one of its type, which bore the imprint of Elsevier’s Excerpta Medica. The follow up post reported there were a total of 6 journals of the type mentioned in the original report. Elsevier issued a statement, which read impart…
“It has recently come to my attention that from 2000 to 2005, our Australia office published a series of sponsored article compilation publications, on behalf of pharmaceutical clients, that were made to look like journals and lacked the proper disclosures,” said Michael Hansen, CEO of Elsevier’s Health Sciences Division, in a statement issued by the company. “This was an unacceptable practice, and we regret that it took place.”
