Human granulocyte-colony stimulating factor (hG-CSF) cDNA was expressed in the methylotrophic yeast Pichia pastoris under the control of the alcohol oxidase (AOX1) promoter. An expression vector for hG-CSF secretion was constructed using vector pPIC9. Higher levels of hG-CSF was obtained using a P. pastoris Mut+ (methanol utilization fast) phenotype. The effects of environmental factors such as...

statement of the problem in recent years, amalgam has been considered a danger for dentistry personnel due to toxicity of mercury (hg) purpose this study aimed at investigating the relationship between scientific indices and dentists’ urine hg level through measuring its concentration rate among dentists with over four years of experience materials and methods thirty dentists with over four yea...

We study quark-gluon plasma (QGP) and hadronic gas (HG) models of the central fireball presumed to be the source of abundantly produced strange (anti-)baryons in S → W collisions at 200 GeV A. We consider how multi-strange (anti-)baryon multiplicities depend on strangeness conservation and compare the HG and QGP fireball scenarios. We argue that the total particle multiplicity emerging from the...

There was little public concern over potential nontarget effects of pesticides until the 1962 publication of Rachel Carson’s Silent Spring (Delaplane, 2000; Moore et al., 2009). Organochlorine insecticides (such as DDT) had been used intensively and were credited for many of the problems highlighted by Carson. Because of their accumulation in the environment and reproductive toxicity in people,...

Control of rodent pests worldwide relies heavily on the use of rodenticides. In the 40s’, O’Connor (1948) isolated and first suggested the use of dicoumarol (a naturally occurring substance responsible for the “sweet clover disease” in cattle) as a rodenticide. In the early 50s’, anticoagulant rodenticides (warfarin and later indane-dione derivatives) replaced the acute poisons with great succe...
