The 90-Year Evolution Of Swine Flu
The current H1N1 swine flu strain has genetic roots in an illness that sickened pigs at the 1918 Cedar Rapids Swine Show in Iowa, report infectious disease experts at the University of Pittsburgh Graduate School of Public Health in the New England Journal of Medicine. Their paper, published online and slated for the July 16 print issue, describes H1N1"s nearly century-long and often convoluted journey, which may include the accidental resurrection of an extinct strain.

Inovio Biomedical H1N1 Influenza DNA Vaccines Demonstrate 100% Responses Against Swine Flu In Vaccinated Pigs
Inovio Biomedical Corporation (NYSE Amex:INO), a leader in DNA vaccine design, development and delivery, announced today that the company"s SynCon™ H1N1 influenza DNA vaccines achieved protective antibody responses against H1N1 swine influenza virus (A/Swine/Iowa/35233/1999) in 100% of pigs immunized with a two-dose vaccine regimen.

New Survey Shows Americans Strongly Support Guaranteed Dental Coverage In Healthcare Reform
Nearly 2 in 3 U.S. adults (63%) think that it is important that dental coverage is part of an overall health reform package, and 40 percent say it is very important, according to a new public opinion survey commissioned by Oral Health America. The survey, sponsored by the Dental Trade Alliance Foundation, and conducted by Harris Interactive(R), was released today at the launch of National Smile Month, the largest independent international campaign promoting good dental care including brushing, regular dental visits, and healthy food choices as well as the need for effective oral healthcare policies.

Psychotherapy Of Depression Changes Biological Parameters?

A group of German investigators demonstrated that the early increase in phosphorylated CREB (pCREB) is related to treatment response and does not depend on pharmacological interventions or brain-derived neurotrophic factor (BDNF) plasma levels. For the first time, cellular biological markers could be associated with response to psychotherapy. The cyclic adenosine monophosphate response element-binding proteins (CREB) and their interaction with brain-derived neurotrophic factor (BDNF) are essential elements in signal transduction pathways important for cellular resilience and neuroplasticity. They play a decisive role in the concept of altered neuroplasticity in major depression. The Authors of this study have previously demonstrated that the increase in phosphorylated CREB (pCREB) in T lymphocytes is significantly associated with clinical improvement in patients treated with antidepressants. In the present study, they focused on patients treated only with psychotherapy to exclude direct pharmacological actions. In addition to pCREB, they also measured the BDNF plasma levels. pCREB in T lymphocytes was determined by Western blot; the BDNF plasma levels with solid-phase ELISA. Psychopathology was evaluated with the Hamilton Rating Scale for Depression (HAMD). Thirty patients meeting DSM-IV criteria for major depressive episodes (MDE) were recruited into this 6-week study. They received interpersonal psychotherapy (IPT) twice weekly. After 6 weeks of IPT, 17 patients responded (reduction of 50% of baseline HAMD); after 1 week of treatment pCREB increased significantly compared to the nonresponder group. Measurement of the BDNF plasma levels revealed no differences between the responder and nonresponder groups. Furthermore, the correlations between BDNF plasma levels and pCREB were not significant. The early increase in pCREB is related to treatment response and does not depend on pharmacological interventions or BDNF plasma levels. For the first time, cellular biological markers could be associated with response to psychotherapy. Psychotherapy and Psychosomatics
