sperm is particularly susceptible to reactive oxygen species (ros) during critical phases of spermiogenesis. however, the level of seminal ros is restricted by seminal antioxidants which have beneficial effects on sperm parameters and developmental potentials. mitochondria and sperm plasma membrane are two major sites of ros generation in sperm cells. besides, leukocytes including polymer phonu...

argyrophilic nucleolar organizer regions (agnors) were determined in 94 pleural, pericardial and peritoneal effusions. the results were correlated with cytologic diagnosis to determine the diagnostic potential of this technique. cytologically the number of normal, reactive and malignant effusions were 32, 28 and 34 respectively. the mean agnor counts for normal, reactive and malignant specimens...

• Reactive DOPO derivatives do not leach during fire use in epoxy products. exhibit dual gas and condensed phase activity. Self–extinguishing smoke suppression are exhibited via aromatic hardeners. Epoxy resins widely applied industry for producing safe materials. Unfortunately, have the disadvantage of being highly flammable thus require suitable modifications with reactive or non-reactive fla...

as dyes are the most important pollutants of many industrial wastewaters. a large amount of reactive black 5 enters the environment in iran because of the use of this dye in iran's textile industries, so the goal of this study was to survey the catalytic ozonation process with bone char in removal of reactive black 5 dye from synthetic wastewater. in this experimental study bone char (bc) was p...

â background: hepatitis b is still a major health problem in many parts of the world. in some developing countries the most common cause of chronic hepatitis and liver cirrhosis is hepatitis b virus (hbv). the progression of chronic hepatitis b to cirrhosis andâ  hepatocellular carcinoma (hcc) include such viral factors as genotype c and high levels of serum hbv dna in addition to host factors ...

The current commercial application of ink-jet reactive inks to cotton fabrics has been through pre-treating with pad liquor prior to printing. In This study made an effort to provide a single phase ink-jet printing process for printing cotton fabric using the novel cationic reactive dye in ink’s formulation. Cotton fabric was printed upon with the novel cationic reactive dye and commercial anio...

Faraci, Frank M. Reactive oxygen species: influence on cerebral vascular tone. J Appl Physiol 100: 739–743, 2006; doi:10.1152/japplphysiol.01044.2005.—Reactive oxygen species have multiple effects on vascular cells. Defining the sources and the impact of the various reactive oxygen species within the vessel wall has emerged as a major area of study in vascular biology. This review will focus on...

It has long been known that at the level of the midbrain pontine junction there is a neural mechanism essential for micturition. Contraction of the urinary bladder in response to increased intravesicular pressure is abolished in the cat following a subcollicular, but not after an intercollicular decerebration.' Electrical stimulation of the brain stem at the level of the inferior colliculus evo...

Investigation of volitional animal models of resistance training has been instrumental in our understanding of adaptive training. However, these studies have lacked reactive force measurements, a precise performance measure, and morphological analysis at a distinct phase of training - when initial strength gains precede muscle hypertrophy. Our aim was to expose rats to one month of training (70...
