Background and aims: Air pollution is one of the health problems worldwide. Previous epidemiological studies have investigated the impacts of air pollution on respiratory and cardiovascular diseases. The aim of this study was to determine the associations between air pollution levels and different health indicators among world countries. Methods: This eco...
Purpose: Ischemia-Reperfusion (IR) injury is one of the most common cardiac disorders leading to irreversible heart damage. Many underlying mechanisms seem to be involved, among which disruption of cellular autophagy balance. Since physical training has a beneficial effect on the improvement of autophagy balance, it may have a cardioprotective effect against IR injury. This study investigates t...
The Northern Dvina River flowing into the White Sea may be one of main sources microplastic (MP) pollution in Arctic region. coastal sediments act as an intermediate link transport microplastics to areas and Barents Seas. µFT-IR Py-GC/MS methods were used determine that up 200 particles or 120 mg MP per kg could accumulate River. Coastal tend ABS PS plastic with a particle size around µm. accum...
The microbial faecal pollution of rivers has wide-ranging impacts on a variety of human activities that rely on appropriate river water quality. Thus, detailed knowledge of the extent and origin of microbial faecal pollution is crucial for watershed management activities to maintain safe water use. In this study, the microbial faecal pollution levels were monitored by standard faecal indicator ...
the east mediterranean region suffers from high levels of air pollution which has a negative impact on pregnancy outcomes. this work systematically reviews the epidemiological evidence on maternal exposure to air pollution and adverse pregnancy outcomes in the region. relevant papers and reports published between 2000 and 2014 were searched. combinations of search terms including countries, exp...
The existence of conventional dendritic cells (cDCs) has not yet been demonstrated outside mammals. In this article, we identified bona fide cDCs in chicken spleen. Comparative profiling of global and of immune response gene expression, morphology, and T cell activation properties show that cDCs and macrophages (MPs) exist as distinct mononuclear phagocytes in the chicken, resembling their huma...
A resistance locus to leukemogenesis in mice by A-RadLV (a variant of the radiation leukemia virus) is described. This locus, Rrv-1, was mapped to subregions I-A, I-B, and I-J of the H-2 complex. It is suggested that Rrv-1 may be in complementation with a second locus to the right of it, between Rrv-1 and H-2D. This localization and the complementation of the two loci for resistance are charact...
