Pressure sores, and especially ischial pressure sores, are a serious concern in the life of paraplegic patients. The treatment of this pathology is obviously surgery, and several local flaps can be used for coverage. However, recurrent pressure sores in an active patient can be frustrating if all local flaps have ...

BACKGROUND: Pressure ulcers are a frequent complication of bed rest. The development of an efficient and low cost pressure relieving system for the prevention of bed-sores would be of considerable hospital health and economic interest. Our study was designed to determine the effectiveness in pressure-sore prevention of an interface pressure-decreasing ...

This paper presents computational experiments that illustrate how one can precisely conceptualize language evolution as a Darwinian process. We show that there is potentially a wide diversity of replicating units and replication mechanisms involved in language evolution. Computational experiments allow us to study systemic properties coming out of populations of ...

Surgery puts patients at risk for developing pressure ulcers. Studies examining factors most likely associated with intraoperatively acquired pressure ulcers have not resulted in the development of a risk assessment tool specific to the surgical patient population. To ascertain the current national rate and potential risk factors of intraoperatively acquired ...

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 ...

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 ...

Despite the prevalence of orthopaedic injuries to horses, there is no objective means of quantifying the intensity of musculoskeletal pain. Mechanical nociceptive thresholds (MNT) can be measured repeatably by pressure algometry in horses and MNTs are correlated with both severity of clinical signs and subjective scores of muscle pain on ...
