this paper presents  the  levels  of total  mercury  (t-hg)  in  dorsal  muscle,  liver  and  spleen of pike  (esox lucius) from  anzali  lagoon  in iran.  sampling were  carried  out from  july  2004 to july 2005. in addition 78 samples were collected. t-hg concentration  were  calculated  in relation to biometric factors. t-hg was measured by the leco ama 254 advanced mercury analyzer (usa) a...

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...

Copper (Cu) and mercury (Hg) enter aquatic ecosystems from different sources threatening health of aquatic organisms such as fish. As such, in this investigation, determinaing, Cu and Hg toxic concentration in Caspian roach (Rutilus rutilus caspicus), was undertaken. Acute toxicity of Cu and Hg were determined in fish specimen under semi-static condition. Caspian roach fry (~ 1 g) were exp...
