Testing Hepatitis A virus antibody in oral fluid among the prospective vaccinees foster the need of new oral HAV rapid test
High Prevalence of Hepatitis A virus Antibody among Bangladeshi Children and Young Adults Warrants Pre-immunization Acreening of Antibody in HAV Vaccination Strategy
Serum samples from 465 subjects aged between 1 and 25 years were tested
for antibody against hepatitis A virus (HAV) [anti-HAV IgG and IgM] to
determine the seroprevalence of HAV antibody and do a cost-benefit
analysis for decision making about vaccination against HAV among the
general population of Bangladesh. A high prevalence of anti-HAV (74.8%)
was observed in the study population; the whole study population was
found positive for anti-HAV by the age of 25 years. On performing the
cost-benefit analysis, it was found that the cost for vaccination with
screening for anti-HAV was almost three times cheaper than vaccination
without screening. Thus, in the present socioeconomic condition of
Bangladesh, a policy based on screening for HAV antibody before
vaccination is recommended
Seroprevalence of rubella among urban and rural Bangladeshi women emphasises the need for rubella vaccination of pre-pubertal girls

The Third Fermi Large Area Telescope Catalog of Gamma-ray Pulsars
International audienceWe present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs) discovered in deep radio searches of LAT sources will likely reveal pulsations once phase-connected rotation ephemerides are achieved. A further dozen optical and/or X-ray binary systems co-located with LAT sources also likely harbor gamma-ray MSPs. This catalog thus reports roughly 340 gamma-ray pulsars and candidates, 10% of all known pulsars, compared to known before Fermi. Half of the gamma-ray pulsars are young. Of these, the half that are undetected in radio have a broader Galactic latitude distribution than the young radio-loud pulsars. The others are MSPs, with 6 undetected in radio. Overall, >235 are bright enough above 50 MeV to fit the pulse profile, the energy spectrum, or both. For the common two-peaked profiles, the gamma-ray peak closest to the magnetic pole crossing generally has a softer spectrum. The spectral energy distributions tend to narrow as the spindown power decreases to its observed minimum near erg s, approaching the shape for synchrotron radiation from monoenergetic electrons. We calculate gamma-ray luminosities when distances are available. Our all-sky gamma-ray sensitivity map is useful for population syntheses. The electronic catalog version provides gamma-ray pulsar ephemerides, properties and fit results to guide and be compared with modeling results

Medicinal Plants of India
Crude extracts of fruits, herbs, vegetables, cereals and other plant materials rich in
phenolics and antioxidant activity are of prime interest to the food industry because
of their ability to retard oxidative degradation of lipids and hence improve the quality
and nutritional value of functional food. Concomitantly, the importance of antioxidant
constituents of plant materials in the maintenance of health and protection from coronary
heart disease and cancer is also raising interest among scientists, food manufacturers
and consumers as part of the current trend towards the use of herbal medicine. In
addition, the use of complementary alternative medicine (CAM) by patients suffering
from chronic disorders, such as cancers, heart, stroke and immune disorders has been
well documented. CAMs are either used on their own (alternative treatments) or in
addition to conventional medicine (complementary treatments). CAMs can be grouped
into herbal medicines derived from medicinal plants, food supplements that include
vitamin preparations, trace elements and other substances such as omega-3 fatty acid
