GB virus B (GBV-B), which infects tamarins, is the virus most closely related to hepatitis C virus (HCV). HCV has a protein (p7) that is believed to form an ion channel. It is critical for viability. In vitro studies suggest that GBV-B has an analogous but larger protein (p13). We found that substitutions of the -1 and/or -3 residues of the putative cleavage sites (amino acid 613/614 and 732/73...

The histone gene cluster on mouse chromosome 3 has been isolated as a series of overlapping P1 clones, covering 110-120 kb, by probing with the histone H3-614 gene that had been mapped previously to mouse chromosome 3. There are genes for 10 core histone proteins present in a 55-kb cluster within this contig. There are three histone H3 genes, two of which are identical; four histone H2a genes, ...

Many studies have shown that susceptibility to epilepsy is increased during nonrapid eye movement (NREM, slow-wave) sleep whereas rapid eyemovement (REM) sleep suppresses seizure occurrence. Therefore, it is postulated that rapid eye movement sleep is a natural antiepileptogenic system in the body during the human wake–sleep cycle [1–3]. Because it is demonstrated that stimulation of the pedunc...

sugarcane mite, oligonychus sacchari mcgregor, is one of the most important pests of sugarcane plant in khuzestan province, southwest of iran. during a two-year study (2007-2008), the biology of the sugarcane mite, o. sacchari, was investigated on three commercial varieties cp48-103, cp57-614 and cp69-1062 under laboratory conditions (temperature 30±1° c, rh% 60±5 and a photoperiod of 16:8 (l:d...

The filamentous cyanobacterium Anabaena sp. strain PCC 7120 forms a periodic pattern of nitrogen-fixing heterocysts when grown in the absence of combined nitrogen. PatA is necessary for proper patterning of heterocysts along filaments. In this study, apparent transcriptional start points (tsps) were identified at nucleotides -305, -614, and -645 relative to the translational start site (-305, -...
