Several components of the Fanconi anaemia (FA) family of proteins allow the formation of the DNA repair complex foci formed by proteins such as BRCA1/2 and RAD51. Because the genes that participate in the DNA repair pathway have been described as low-penetrance breast cancer susceptibility genes, we postulated that variants in FA genes could also be associated with sporadic breast cancer risk. ...
In this paper the authors present method of estimation a region, waiting period and probability strong earthquakes with K S ≥ 13.5 ( M 6.0) in Kamchatka region based on combination mid-term short-term predictive signs accompanying earthquake formation. The seismological parameter ξ P was taken as precursor. It calculated basis probabilistic model seismic regime. A complex ionospheric parameters...
Background: Leishmaniasis is an infection caused by a protozoan of the genus Leishmania. This descriptive and cross-sectional study was done in order to determine the seroepidemiology of visceral leishmaniasis in East Myankooh area, in Lorestan Province during 2004 – 2005 time period. Materials and methods: This study was a descriptive, cross-sectional study. Multi stage sampling was performed...
Between weeks 40 2020 and 8 2021, the World Health Organization European Region experienced a 99.8% reduction in sentinel influenza virus positive detections (33/25,606 tested; 0.1%) relative to an average of 14,966/39,407 (38.0%; p < 0.001) over same time previous six seasons. COVID-19 pandemic public health physical distancing measures may have extinguished 2020/21 seasonal epidemic with j...
Loss of imprinting at insulin-like growth factor II (IGFII), in association with H19 silencing, has been described previously in a subgroup of Beckwith-Wiedemann syndrome (BWS) patients who have an elevated risk for Wilms' tumor. An equivalent somatic mutation occurs in sporadic Wilms' tumor. We describe a family with overgrowth in three generations and Wilms' tumor in two generations, with pat...
Venezuelan equine encephalitis virus (VEEV) has been the causative agent for sporadic epidemics and equine epizootics throughout the Americas since the 1930s. In 1969, an outbreak of Venezuelan equine encephalitis (VEE) spread rapidly from Guatemala and through the Gulf Coast region of Mexico, reaching Texas in 1971. Since this outbreak, there have been very few studies to determine the northwa...
Materials and Methods Linkage analysis in familial breast and ovarian cancer and studies of Tissue Samples and DNA Extraction. OvarÃ-an tumor tissue samples were allelic deletion in sporadic ovarian tumors have suggested that chromo some 17q may be the location of a gene of importance in ovarian cardilogenesis. We have examined tumor and normal DNA samples from 120 patients with ovarian tumors ...
