The sigma1 ( 1) receptor represents a unique intracellular neuronal protein modulating several neurotransmitter responses with relevant effects on cognitive functions. We examined here its expression and behavioral efficacy during aging. The 1 receptor expression was examined in young (2 months old) and aged (24 months old) C57BL/6 mouse brain using comparative RT-PCR and immunohistochemistry. ...

We examine the constraints on high-redshift star formation, ultraviolet and X-ray preionization, and the epoch of reionization at redshift zr, inferred from the recent WMAP-5 measurement, e 1⁄4 0:084 0:016, of the electronscattering optical depth of the cosmic microwave background (CMB). Half of this scattering can be accounted for by the optical depth, e 1⁄4 0:04Y0.05, of a fully ionized inter...

In the first half of the last century tuberculosis was the main focus of attention amongst all respiratory diseases. Bronchial asthma is a serious global health problem. The present study was carried out to estimate magnesium levels in serum in pulmonary tuberculosis and bronchial asthma cases and to compare them with the serum magnesium levels of controls. This study was undertaken in 120 subj...
