A convincing body of evidence now exists to indicate that the ubiquitous protozoan Toxoplasma gondii can cause permanent behavioral changes in its host, even as a consequence of adult-acquired latent infection. Such behavioral alterations appear to be the product of strong selective pressures for the parasite to enhance transmission from ...

[Truncated abstract] Pressure ulcers affect a substantial proportion of patients admitted to health care services worldwide imposing considerable physical, social and economic burdens on patients and communities. As largely preventable wounds their prevalence is likely to escalate as the life expectancy and incidence of people living longer with other chronic ...

Pressure ulcers represent complex wounds that are difficult to prevent or manage. Guidelines for prevention include identifying patients at risk, reducing the effect of pressure, friction, shear forces, and assessing co-morbidities such as nutritional status. Management should follow eight treatment strategies including accurately assessing the ulcer, relieving pressure, assessing pain ...

Decubitus ulcers appear to be associated with insidious trauma. Differential diagnosis can be tricky, and etiology is controversial with sustained localized pressure which plays a significant role. Sustained pressure can stretch soft tissues and blood vessels, causing multiple microthrombi around the point of maximum compression. This leads to prolonged ischemia ...

BACKGROUND: Alternative splicing (AS) has been regarded capable of altering selection pressure on protein subsequences. Particularly, the frequency of reading frame preservation (FRFP), as a measure of selection pressure, has been reported to be higher in alternatively spliced exons (ASEs) than in constitutively spliced exons (CSEs). However, recently it has ...

Pain is regarded as a risk factor in pressure ulcer development by contributing to immobility. Pressure-induced vasodilatation (PIV) is a mechanism whereby cutaneous blood flow increases in response to progressive locally applied pressure, thereby delaying the occurrence of ischaemia and appearing to be a protective response to local pressure. When ...
