Demecolcine (Colcemid), an inhibitor of spindle fiber formation in M phase, induced apoptosis in V79 cells. At a concentration of 0.01 microgram/ml demecolcine, V79 cells proliferated exponentially as well as controls, although temporal M phase accumulation occurred 6 h after the addition of demecolcine. At 0.1 microgram/ml, the cells became hyperploid after remaining in the M phase for some ti...

Slave particle approaches are widely used in studies of exotic quantum phases. A complete description beyond mean field also contains dynamical gauge fields, while a simplified procedure considers Gutzwiller-projected trial states. We apply this in the context of bosonic models with ring exchanges realizing so-called exciton Bose liquid (EBL) phase and compare a Gutzwiller wave function against...

in recent years there has been considerable interest in the synthesis and separation of enantiomers of organic compounds especially because of their importance in the biochemistry and pharmaceutical industry. high-performance liquid chromatography is a very useful method for the direct separation of enantiomers. however, about 30−40 years ago, commercially available chiral stationary phases wer...

background: hormonal changes as a factor influencing the emotional state of women have an important role in the incidence of suicide. the aim of this study is to investigate changes in fsh-lh, estrogen, and progesterone hormones in women attempting suicide by drugs and chemicals. methods: in this cross-sectional study, women of reproductive diagnosed with drug and chemical poisoning who were ho...
