introduction: estrogen is one of the gonadal hormones that has multiple beneficial actions in central nervous system and involves in learning and memory. alzheimer's disease (ad) is a progressive neurodegenerative disorder that impairs patient memory. the human nucleus basalis of meynert (nbm) is severely affected in alzheimer's disease. so in this study the effect of peripheral (intr...

The physics implications of the just published salt phase data from the SNO experiment are examined. The effect of these data on the allowed ranges of the solar neutrino oscillation parameters, ∆m21 and sin 2 θ12, are studied in the cases of twoand threeneutrino mixing. In the latter case we derive an upper limit on the angle θ13. Constraints on the solar νe transitions into a mixture of active...

aneurysms of gastric vessels (dieulafoy`s disease, caliber-persistent artery) are thought to be of malformative rather than degenerative origin. they are usually single, located in the submucosa, usually on the lesser curvature, and characterized by a large tortuous vessel surmounted by a small defect in the overlying mucosa. when the lesion perforates, massive and sometimes fatal hemorrhage ma...

DNA polymerase zeta (Pol ζ) participates in translesion synthesis (TLS) of DNA adducts that stall replication fork progression. Previous studies have led to the suggestion that the primary role of Pol ζ in TLS is to extend primers created when another DNA polymerase inserts nucleotides opposite lesions. Here we test the non-exclusive possibility that Pol ζ can sometimes perform TLS in the absen...
