BACKGROUND Previous in vitro studies have demonstrated that polyvinylpyrrolidone coated silver nanoparticles (PVP-coated AgNPs) have antiviral activity against HIV-1 at non-cytotoxic concentrations. These particles also demonstrate broad spectrum virucidal activity by preventing the interaction of HIV-1 gp120 and cellular CD4, thereby inhibiting fusion or entry of the virus into the host cell. ...

Polar auxin transport is essential for the formation of continuous vascular strands in the plant body. To understand its mechanism, polar auxin transport inhibitors have often been used. However, the role of auxin in vascular differentiation at the unicellular level has remained elusive. Using a Zinnia elegans cell culture system, in which single mesophyll cells transdifferentiate into trachear...

abstract in vitro leaf explants of gf677 hybrid rootstock and rabi cultivar were placed on mql medium supplemented with bap at 0, 1, 2, 3 and 4 mg/l and naa at 0, 0.15 and 0.3 mg/l concentrations. the results revealed that bap, naa, genotype and their interactions had significant effect on both percentage and mean number of the regenerated shoots. for gf677, the highest percentage of shoot rege...

Seeds of Bauhinia acuminata L. were used as an experimental material for micropropagation. The effect of growth regulators concentrations on morphogenetic development was studied. Seeds were germinated on MS medium supplemented with GA3 (0.10, 1.0 and 2.0 mgL -1 ) and without GA3. Satisfactory germination was observed at media with 1.0 mgL -l GA3. Subsequent propagation from plantlet was perfor...

 Abstract Objective: To investigate the anesthesia-postoperative awakening time (AT) of hepatitis- related cirrhosis patients and their relations to grading scores, portal venous pressure (PVP), prealbumin (PA), and age, to predict postoperative AT and provide a basis for adjustment of anesthetic doses during operation. Methods: Atotal of 71 patients with hepatic cirrhosis and hypersplenism at ...
