Research ArticleOpen accessIn the abstractEffect of Storage Time and Temperature on Serum AnalytesAbdoljalal MarjaniInformation on the measured concentration of serum analytes during storage of serum samples is often incomplete and sometimes contradictory. The 10 analytes have not studied in this area in healthy subjects. The aim of present study was designed to determine the effect of storage time and temperature on the laboratory results of 10 analytes in sera from apparently healthy adult … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 8,870 accessesView PDFCite
Research ArticleOpen accessIn the abstractUrinary Tract Infection-A Survey of Local PopulationShaon Ray Chaudhuri, Ashoke Ranjan Thakur, Poulomi Nandy, Santanu SamantaUrinary Tract Infection, commonly known as UTI, affects as many as 50% women at least once during their lifetime. All individuals are susceptible to Urinary Tract Infection (UTI); however the prevalence of infection differs with age, sex and certain predisposing factors. With the above background in mind we conducted a survey of the local population (women of 3 age groups) … …American Journal of Infectious Diseases, Vol. 4, Issue 2 · 30 Jun 2008 · 7,778 accessesView PDFCite
Research ArticleOpen accessIn the abstractNoninvasive Measurement of Fecal Progesterone Concentration in Toy Poodles by Time Resolved Fluoroimmunoassay (TR-FIA)Satoshi Sugimura, Kaori Narita, Hideaki Yamashiro et al.Progesterone is an important reproductive hormone and measurement of its level by repeated blood samplings is beneficial to monitoring of estrus cycle. However, since toy poodles have a small body size and thin-walled blood vessels, repeated blood samplings cause stress and affect their preparation for mating or artificial insemination (AI). Therefore, a noninvasive method for monitoring progesterone concentration should be … …American Journal of Animal and Veterinary Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 6,564 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Metoprolol and Felodipine in Binary Mixture Using Chemometric-Assisted Spectrophotometric and High-Performance Liquid Chromatographic-UV MethodsHesham Salem, Ola M. AbdallahFour methods were developed for simultaneous determination of metoprolol and felodipine without previous separation. In the first method both drugs were determined using first derivative UV spectrophotometry, with zero crossing measurement at 222 and 235 nm for metoprolol and felodipine, respectively. The second method depends on first derivative of the ratios spectra by measurements of the amplitudes at 250.1 nm … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 8,025 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Diloxanide Furoate and Metronidazole in Binary Mixture Using First Derivative of the Ratio-Spectra and High-Performance Liquid Chromatography-UV MethodsNora H. Al-ShaalanTwo methods are presented for simultaneous determination of diloxanide furoate and metronidazole. The first method depends on first derivative of the ratio-spectra by measurements of the amplitudes at 242.5 and 285.5 nm for diloxanide furoate and 225.5 and 300 nm for metrinidazole. Calibration graphs were established for 2-100 μg mL-1 for diloxanide furoate and 1-50 μg mL-1 for metronidazole. In … …American Journal of Applied Sciences, Vol. 4, Issue 2 · 28 Feb 2007 · 7,713 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Administration of Alpha-Melanocyte Stimulating Hormone (α-MSH) on Some Hematological Values of Alloxan-induced Diabetic RatsKamal M.S. MansiThis study was designed to evaluate the role of alpha- melanocyte stimulating hormone (α-MSH) on heart rate and some hematological values in alloxan induced diabetic rats. 40 male white rats were divided into four experimental groups: control, diabetic, α-MSH-treated and α-MSH-treated diabetic. At the end of the experimental period (3weeks), animals in all four groups were fasted for 12 hrs … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 1 · 31 Mar 2006 · 7,366 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Whole-body Magnetic Field on Changes of Glucose and Cortisol Hormone in Guinea PigsS. Zare, H. Hayatgeibi, S. Alivandi, A. G. EbadiThe main goal of this study was to evaluate the possible effect of whole-body Magnetic Field (MF) exposure on the variations of glucose and corlisol hormone levels on 36 adult male Guinea pigs in four separate experiments, male Guinea pigs, were exposed to sinusoidal 5Hz, 0.013 μT and 50 Hz-0.207 μT MF. Duration of exposure was 2 and 4 h/day … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 4 · 31 Dec 2005 · 6,270 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvidences of Apoptosis in Hepatitis C Virus-Infected Hepatocytes and Peripheral Blood Monocuclear Cells in the Absence of Liver InjuryViviana Falcón, Nelson Acosta-Rivero, Mineko Shibayama et al.Understanding the mechanism of Hepatitis C Virus (HCV) pathogenesis is an important part of HCV research. In this study, the presence of apoptosis in HCV-infected liver and Peripheral Blood Mononuclear Cells (PBMC) from patients positive for anti-HCV antibodies and negative for serum HCV-RNA was investigated. The samples obtained from 21 patients were studied by in situ Hybridization (ISH), Immunofluorescence, TUNEL … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,975 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvidences of Hepatitis C Virus Replication in Hepatocytes and Peripheral Blood Monocuclear Cells from Patients Negative for Viral RNA in SerumViviana Falcón, Nelson Acosta-Rivero, Mineko Shibayama et al.In this study, we examined the expression of hepatitis C virus (HCV) components in hepatocytes and peripheral blood mononuclear cells (PBMC) from patients positive for anti-HCV antibodies and negative for serum HCV-RNA. The samples obtained from 25 randomly selected patients (13 of 25 patients showed no histological evidences of chronic hepatitis and had normal serum ALAT and GGTP levels) were … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 7,164 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of 50 HZ Magnetic Field on Some Factors of Immune System in the Male Guinea PigsH. Sedghi, S. Zare, H. Hayatgeibi et al.This study investigated the bio-effects of 50 Hz MF exposure on some Immunological factors (ACTH, cortisol and glucose levels) in male Guinea pigs. The capacity of 50 Hz Electromagnetic Fields (EMF) to interfere in the weakness of endocrine system has been a relevant fact into the scientific community, since we are more susceptible for this kind of exposure, in modern … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 7,997 accessesView PDFCite
