Cell adhesion is a critical step in cancer metastasis, activated by extracellular forces such as pressure and shear. Reducing AKT1, but not AKT2, ablates the increase in cancer cell adhesion associated with 15 mm Hg increased extracellular pressure. To identify the determinants of this AKT isoform specificity, we exchanged the ...

In this paper, we discuss findings from a study that used panoramic video-based virtual environments (PVVEs) to induce self-reported anger. The study assessed "immersiveness" and physiological correlates of anger arousal (i.e., heart rate, blood pressure, galvanic skin response [GSR], respiration, and skin temperature). Results indicate that over time, panoramic video-based ...

Do the inference strategies people select depend on the magnitude of time pressure? Is this dependency modified by the type of time pressure? These questions are addressed in three experimental studies in which participants made inferences after having searched for information on a computerized information board. In Study 1, time ...

Historical models postulate that genocide cannot occur without the ideology and decisions of its authoritarian perpetrators and the indifference of bystanders. These models do not address genocidal risks from ecocide. Study objectives were to assess 1) the role of Malthusian pressures in recent genocides, 2) the role of ecocide and ...

Pressure ulcers occur in up to 14% of acute hospitalizations. They cause pain, decreased quality of life, increased morbidity, and prolonged hospitalizations. Treatment includes pain control, nutritional support, relieving pressure, removing devitalized tissue, and by using dressings and medications, providing an environment in which healing can occur. Even with optimal ...

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 ...

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 ...
