Nucleus is a highly compartmentalized part of the cell where the key processes of genome functionality are realized through the formation of non-membranous nuclear domains. Physically nuclear domains appear as liquid droplets with different viscosity stably maintained throughout the interphase or during the long diplotene stage of meiosis. Since nuclear body surface represents boundary between ...

Polymyositis is a nonsuppurating inflammatory disease of the striated muscle characterized clinically by the presence of proximal muscular weakness that is sometimes associated with pain. 1 This disease falls within a broader category known as idiopathic inflammatory myopathy, which includes the forms of myositis that are secondary to connective tissue disease and neoplasms and myositis with in...

Decayed-wood samples were collected from a naturally-infected bridge made of Quercus robur. Fruiting bodies of the white-rot basidiomycetes Hymenochaete rubiginosa and Stereum hirsutum were sampled. The white-rot fungus Fuscoporia ferrea and the secondary saprobiont Mycena galericulata were identified from the rotten wood by means of rDNA-ITS sequencing. The topochemistry of lignin degradation ...

Derepression of transposable elements (TEs) in the course of epigenetic reprogramming of the mouse embryonic germline necessitates the existence of a robust defense that is comprised of PIWI/piRNA pathway and de novo DNA methylation machinery. To gain further insight into biogenesis and function of piRNAs, we studied the intracellular localization of piRNA pathway components and used the combin...

BACKGROUND Secondary toxicity in mammals and birds that consume animals containing residues of anticoagulant rodenticides represents a persistent conflict between conservation, agriculture and environmental contamination. Chlorophacinone residues in black-tailed prairie dogs (Cynomys ludovicianus) represent a secondary exposure hazard to predatory and scavenging avian and mammalian species in t...

Oil bodies of plant seeds contain a triacylglycerol matrix surrounded by a monolayer of phospholipids embedded with alkaline proteins called oleosins. Oil bodies isolated from maize (Zea mays L.) in a medium of pH 7.2 maintained their entities but aggregated when the pH was lowered to 6.8 and 6.2. Aggregation did not lead to coalescence and was reversible with an elevation of the pH. Further de...

over the years, there has been an obvious pollution problem in lagos area, nigeria with high population of over eleven million and the near absence of waste management infrastructures. concentrations of some pollution parameters and trace elements (temperature, ph, salinity, so42-, no3-, po43-, f-, do, bod, cod and coliform, cr, co, ni, ag, cd and pb) were determined from water bodies of isolo ...

Shotgun wounds can result in devastating functional and aesthetic consequences for patients. There is no consensus in terms of removing or retaining foreign bodies such as shotgun pellets. In this report a 54-year-old man who suffered from accidental shotgun wounds on the face approximately 26 years ago is presented. Although most of pellets were still present, there were no symptoms such as po...
