We studied the spatiotemporal characteristics of cortical activity in early visual areas and the fusiform gyri (FG) by means of magnetoencephalography (MEG). Subjects performed a visual classification task, in which letters and visually similar pseudoletters were presented in different surrounds and under different task demands. The stimuli appeared in a cued half of the visual field (VF). We o...

Fibrinogen (Fg), the major clotting protein in blood plasma, plays key roles in blood coagulation and thrombosis. In addition, this 340 kD glycoprotein is a stress inducible protein; its synthesis is dramatically upregulated during inflammation or under exposure to stress such systemic infections. This regulation of Fg expression indicates that Fg also participates in the host defense system ag...

Fournier's gangrene (FG) is a rare but severe necrotizing fasciitis of the external genitalia that may complicate the clinical course of hematologic malignancies and sometimes may be the first sign of the disease. The clinical course of FG is very aggressive and the mortality is still high despite the improvement in its management. Early recognition of FG and prompt appropriate treatment with s...

Fournier’s gangrene (FG) is a rapid progressive disease with high mortality and is caused by polymicrobial infection. FG usually begins with infection and affects fascias in (the perianal and) perineal regions as well as the abdominal wall and other organs. Although this disease has been recognized for many years, there are only a few cases reported in the world and few from China. Here, we rep...

Fibrinogen (Fg) nanofibrils were prepared by the ethanol-induced self-assembly of Fg molecules, which can be used as fibrous scaffolds to organize gold nanoparticles (NPs).

Physical activity plays a crucial role in bone mass acquisition during childhood and adolescence, with weightbearing and high-impact sport activities being more beneficial. This study sought to evaluate the impact of different sports activities on bone mineral density and content in male Portuguese athletes. Seventy adolescent boys (aged 12-15 years) including 28 futsal players (FG), 20 swimmer...

Marine bacterioplankton were isolated and grown in batch cultures until their growth became limited by organic carbon (C), nitrogen (N), or phosphorus (P). Samples were taken from the cultures at both the exponential and stationary phases. The elemental composition of individual bacterial cells was analyzed by X-ray microanalysis with an electron microscope. The cell size was also measured. The...
