aim : the aim of this study was to identify and compare the pattern of acute viral hepatitis in two regions of iran. background : the epidemiological pattern of acute hepatitis varies across the globe depending on geographic region, health status, socioeconomic conditions and differences in exposure to etiological factors. patients and methods : a cross-sectional study was carried out among 357...

measles is one of the viral and extremely contagious and acute diseases of childhood affecting almost all children. prior to the discovery of the measles vaccine, the mortality from this disease was one of the highest child mortality figures, especially in the developing countries, with the death rate ranging over 5 to 10% of the infected? before the vaccination program i was launched in the co...

This review was presented to suggest if viruses could be used as fecal indicators for drinking water and treated sewage pollution. The failure of bacterial in a lot cases indicate viral pollution indicates that may fail express sewage. We explain this statement viruses, especially enteric are generally secreted the feces infected or carrier persons. Thus, it always expresses contamination conse...

Computational modeling and molecular simulation techniques have become an integral part of modern molecular research. Various areas of molecular sciences continue to benefit from, indeed rely on, the unparalleled spatial and temporal resolutions offered by these technologies, to provide a more complete picture of the molecular problems at hand. Because of the continuous development of more effi...

Membrane-associated events during peroxisomal protein import processes play an essential role in peroxisome functionality. Many details of these processes are not known due to missing spatial resolution of technologies capable of investigating peroxisomes directly in the cell. Here, we present the use of super-resolution optical stimulated emission depletion microscopy to investigate with sub-6...

The phosphate carrier (PiC) of mammalian mitochondria is synthesized with a cleavable presequence, in contrast to other members of the mitochondrial family of inner membrane carrier proteins. The precursor of PiC is efficiently imported, proteolytically processed, and correctly assembled in isolated mitochondria. Here we report that a presequence-deficient PiC was imported with an efficiency of...

Infectious diseases can impact the physiological performance of individuals, including their mobility, visual acuity, behavior and tolerance and ability to effectively respond to additional stressors. These physiological effects can influence competitiveness, social hierarchy, habitat usage, migratory behavior and risk to predation, and in some circumstances, viability of populations. While the...

Viral variants of different phenotypes are present in the central nervous system (CNS) and lymphoid tissues of carrier mice infected at birth with the Armstrong strain of lymphocytic choriomeningitis virus. The CNS isolates are similar to the parental virus and cause acute infections in adult mice, whereas the lymphoid isolates cause chronic infections associated with suppressed T-cell response...

context several risk factors play the role in the development of hepatocellular carcinoma (hcc) from which chronic hepatitis b and c infections are the most important ones. dna integration of hepatitis viruses alters the function of critical genes promoting malignant transformation of virus-infected liver cells. evidence acquisition there are remarkable geographic differences in prevalence of c...
