The involvement of elements in the pathological process of primary hypertension has been established. The serum levels of copper, iron, zinc, sodium, potassium and calcium were studied by atomic absorption spectrophotometery and flame photometry in hypertensive and normal subjects. Serum copper and zinc levels were increased in hypertensive patients (25.5% and 14.7% respectively) as compar...

ABSTRACT. Spectrophotometric investigation of the interaction of Cefpodoxime proxetil (CFP) with Ca, Mg, Mn, Fe, Co, Ni, Cu and Zn in acidic medium showed the formation of 1:1 complex. The absorption spectrum of pure drug exhibits two prominent peaks at 270 and 345 nm. Its spectra scanned at several pH exhibited two isosbestic points (305 and 330 nm) indicating the presence of zwitterionic cond...

BACKGROUND One of the most important items in molecular characterization of food-borne pathogens is high quality genomic DNA. In this study, we investigated three protocols and compared their simplicity, duration and costs for extracting genomic DNA from Linguatula serrata. METHODS The larvae were collected from the sheep's visceral organs from the Yazd Slaughterhouse during May 2013. DNA ext...

Introduction: Our aim was to determine the relationship between genuine premature ejaculation and serum and seminal plasma magnesium. Materials and Methods: In a case-control study carried out between January 2002 and December 2003, 19 patients with premature ejaculation were evaluated and compared with 19 patients without premature ejaculation. Patients with organic and psychogenic causes were...

Scientific data about protein biomarkers which can be used in distinguishing tumor from non tumor brain tissues are increasing. These proteins might be attractive clinical biomarkers, linked or not with survival, or a specific cancer-therapy target. Dihydropyrimidinase proteins (DRP) are members of collapsing response mediator proteins (CRMP); involved in regulation of neuritis guidance and syn...

The effect of the antimicrobial additives benzalkonium chloride and cetylpyridinium chloride on a restorative glass-ionomer dental cement (Fuji IX) has been studied. Both substances were added to the glassionomer at levels of 1%, 2% and 3% by mass at the mixing stage, and various effects were studied. Setting time was altered in most cases, but only slightly. Compressive strength and release we...

Occupational exposure to lead is common among automobile technicians and constitutes 0.9% of total global health burden with a majority of cases in developing countries. The aim of this study was to determine and compare the blood lead levels of automobile technicians in roadside and organised garages in Lagos State, Nigeria. This was a comparative cross-sectional study. Data were collected usi...

This study was undertaken in order to determine heavy metal contents in twelve (n = 12) henna brands and eleven (n = 11) kohl products. An analytical test was performed for Pb, Cd, Cu, and Zn in henna and kohl products using atomic absorption spectrophotometery. The overall mean concentrations of heavy metals in henna varied between 1.2 and 8.9 μg g(-1) for Pb; 0.8 and 18.6 μg g(-1) for Cd; 0.5...

OBJECTIVE This investigation was performed to evaluate the acid resistance of lased enamel and dentin by Er,Cr:YSGG laser to artificial caries-like lesions by spectrophotometry, and the ultrastructure of lased areas was investigated by scanning electron microscopy (SEM) in vitro. BACKGROUND DATA In recent years, many studies have been performed to evaluate the effects of Er,Cr:YSGG laser on d...

based on the molecular modeling studies on two major families of anxiolytics and sedative hypnotics (benzodiazepines and barbiturates) a series of phthalimide derivatives were prepared from corresponding di-methyl phthalate derivatives in two steps, namely trans-amidification and ring closer of di-methyl phthalate with urea and base catalysed condensation of 4-bromobenzyl chloride and benzoyl c...
