background apoptosis or programmed cell death is an essential process for elimination of damaged cells. also, induction of apoptosis is fundamental for treating cancer. screening for agents that induce apoptosis in tumor cells help in the development of novel agents for cancer treatment. numerous studies suggest that the exposure of tumor cells to statins can lead to cell death via two separate...

The present study describes the fragmentation under electron ionization (EI) of gas phase serine and threonine amino acids. Ab initio methods were performed to calculate the fragmentation paths and interpret the mass spectra. The six lowest energy conformers of L-serine, L-threonine and L-allo-threonine were obtained with B3LYP, G3MP2 and MP2 methods. The adiabatic and vertical ionizat...

Fragmentation and growth-fragmentation equations is a family of problems with varied and wide applications. This paper is devoted to the description of the long-time asymptotics of two critical cases of these equations, when the division rate is constant and the growth rate is linear or zero. The study of these cases may be reduced to the study of the following fragmentation equation: ∂ ∂t u(t,...

A study of charm fragmentation into D∗+ s and D + s in e +e− annihilations at √ s = 10.5 GeV is presented. This study using 4.72±0.05 fb−1 of CLEO II data reports measurements of the cross-sections σ(D∗+ s ) and σ(D + s ) in momentum regions above x = 0.44, where x is theDs momentum divided by the maximum kinematically allowed Ds momentum. The Ds vector to vector plus pseudoscalar production ra...

A study of charm fragmentation into D + s and D + s in e + e ? annihilations at p s = 10:5 GeV is presented. This study using 4:720:05 fb ?1 of CLEO II data reports measurements of the cross-sections (D + s) and (D + s) in momentum regions above x = 0:44, where x is the D s momentum divided by the maximum kinematically allowed D s momentum. The D s vector to vector plus pseu-doscalar production...

logistic regression (lr) was used to model urban growth between the years 1987 and 2001 in gorgan city, north east of iran. three groups of variables including economic-social, land use and biophysical variables were used in the modeling practice. using covariance of the independent variables, distance to administrative and sporting centers plus distance to cities were removed. roc (relative op...

semen analysis, sperm dna fragmentation (sdf) and hypo-osmotic swelling test (host) are usually performed for the evaluation of sperm fertilizing ability. there are some debates over the necessity of sdf and host incorporation in male infertility work-up.semen of 77 men was evaluated by sdf and host through three semen analyses. sperm parameters were arranged into different categories: < 5%, 5-...

objective: evaluation of the effects of different doses of antioxidant taurine on oxidative stress and human sperm parameters following cryopreservation. materials and methods: the semen of 20 fertile men were divided to 5 aliquot, one part considered as a fresh after analysis of standard semen parameters (motility, abnormal morphology, viability) and protamine deficiency, dna damage and measu...

Abstract In this study we report chip fabrication process that allows the laser lift-off of sapphire substrate for transfer GaN based thin film flip to carrier wafer. The includes 365-nm ultraviolet LED wafer align bonding with through-AlN-via and lift-off. n-holes diameter 100 µm were etched on epilayers accessing n-type GaN. Through-AlN-via size was 110-µm filled by Cu electroplating method e...
