Background and Objective: Oxidative stress plays an important role in the pathogensis of various diseases, including lung cancer, chronic obstructive pulmonary disease, and atherosclerosis. Total antioxidant capacity plays a significant role in the body’s antioxidant defense, so its assessment is a matter of the utmost importance. Currently, assessment of this capacity is performed in var...

Intraand inter-laboratory variation of in vitro gas production and calculated metabolizable energy (ME, MJ/kg DM) values were studied using 16 test feeds in 7 laboratories. Intra-laboratory variation was low, with six of the seven laboratories having very high relationships in gas production between runs (R2 ≥ 0.96) and slopes that did not differ from unity. Inter-laboratory differences were hi...

Volume 1 • Issue 4 • 1000e104 Biochem Anal Biochem ISSN:2161-1009 Biochem, an open access journal Biological Variation (BV) of quantities examined in laboratory medicine can be described as of three types, namely; variation over the span of life, predictable cyclical variation that can be daily, monthly or seasonal in nature, and random variation [1]. Random variations of analytes which consist...

background: leishmaniasis is an obligate intercellular protozoon that affects animals and human. it has zoonosis and/or anthroponosis transmission. human and veterinary medicine, environmental science and wildlife conservation special­ists have many commonalities in case of visceral leishmaniasis. still the above disciplines respond against leishmaniasis in a separate way.   the aim of this re­...

Arbuscular mycorrhizal fungi (AMF) are common and important plant symbionts. They have coenocytic hyphae and form multinucleated spores. The nuclear genome of AMF is polymorphic and its organization is not well understood, which makes the development of reliable molecular markers challenging. In stark contrast, their mitochondrial genome (mtDNA) is homogeneous. To assess the intra- and inter-sp...

background: los angeles classification is widely adopted as a means of unifying endoscopic observation for gerd. we assessed the inter- and intra-observer variability of la classification. materials and methods: two-hundred fifty-four still images of the lower esophagus taken by an expert endoscopist (rm) were randomly selected and presented to 9 gastroenterologists (2 females, 6 experts, 3 tra...

Purpose: To investigate inter- and intra-individual variation in the levels outputs (concentration multiplied by salivary flow rate) of metabolites patients with primary Sjögren’s syndrome (pSS).

eight accessions of thyme medicinal plant, belonging to iranian endemic thymus daënensis, t. eriocalyx, t. migricus and an unknown thymus spp species, were tested for karyotypic analysis, using squash technique and 2% (w/v) aceto-orcein staining method. chromosomal parameters examined were: short arm (s), long arm (l), total length of chromosome (tl), arm ratio (ar), r-value, total chromosome v...
