Introduction Maintaining oxygen homeostasis is of vital importance for the survival and development of mammalian cells. Hypoxia (below-normal levels of oxygen in air, blood and tissue) can potentially lead to cellular dysfunction and ultimately cell death and is a feature of many pathological conditions. Understanding how reduced oxygen levels may contribute to or even promote disease is a sign...

absorption spectrometer with Zeeman background correction, which eliminates the effect of interfering impurities. It is the only high sensitivity and selectivity instrument that does not require gold amalgam pre-concentration and subsequent regeneration steps. This enables the user to conduct real time monitoring and detection of a mercury vapor. Being combined with an RP-91 Cold Vapor accessor...

Vitamin D3 has a role in many autoimmune diseases and appears to play a function in controlling Rheumatoid Arthritis (RA). The aim of this study is to evaluate the relationship between serum level of vitamin D and RA disease activity score. The serum level of vitamin D in 75 RA patients referred to the rheumatology clinic of Rasoul-Akram hospital was measured. Patients were classified into low,...

 ABSTRACTBackground: 226 Ra and 228 Ra contents in foodstuffs of Ramsar which is a coastal city in the northern part of Iran were determined by gamma spectrometry. Measurement results together with food consumption rates were used to estimate annual effective dose from  226 Ra and 228 Ra, due to consumption of food stuffs by inhabitants of Ramsar city.Materials and Methods: A total of 33 sample...

We proposed a genetic algorithm (GA) approach to solve the genome sequencing problem. The main contribution of this work is to add two ideas to improve the efficiency of the algorithm (1) a Chromosome Reduction Step (CRed) method to shorten the length of the chromosome and thereby the searchspace, and (2) Chromosome Refinement Step (CRef) is a greedy heuristics to locally improve the fitness of...

In Taiwan, leptospirosis is caused mainly by Leptospira santarosai serovar shermani. Suppression subtractive hybridization was employed to isolate DNA fragments present in pathogenic L. santarosai serovar shermani but absent in non-pathogenic L. biflexa serovar patoc. Analysis of 23 subtracted DNA clones revealed 25 gene fragments by BLASTX program. Eight clones showed similarity to transposase...
