In a classic study, Rushton and colleagues presented 20-item scale to assess the altruistic behavior of people: Self-Report Altruism (SRA) scale. This article focuses on development simplified 9-item scale—the 9-SRA scale—describing entire refinement validation procedure using exploratory confirmatory factor analysis. The shows adequate reliability validity represents more parsimonious instrume...

Metformin and thiazolidinediones (TZDs) are believed to exert their antidiabetic effects via different mechanisms. As evidence suggests that both impair cell respiration in vitro, this study compared their effects on mitochondrial functions. The activity of complex I of the respiratory chain, which is known to be affected by metformin, was measured in tissue homogenates that contained disrupted...

SETTING State University of New York Upstate Medical University, Syracuse, New York. PATIENT(S) Forty-one men who visited the andrology laboratory for fertility evaluation. IN...

in this model, we establish an inventory model to determine the optimal inventory replenishment scheme for the economic production quantity (epq) model for imperfect, deteriorating items with sales return service under multiple production and rework setup. in one cycle, production process can produces the products in m production setups and reworks the defective items in one rework setup. the c...

In recent years, a number of studies have been miadle on the respiration of slices of potato tuber tissue (1, 6, 7, 8, 9, 11, 12, 13, 16, 17). \VXhen the slices or dlisks are freshly cut, they have a respiration rate sinmilar to that of the intact tuber. This tissue lhas been termed fresh tissue. \Vhen the fresh disks are kept by aerating them in distilled water or 10-4 Al CaSO4 at 00, the low ...

BACKGROUND Mechanical ventilation is one of the major supportive interventions in intensive care units. Weaning the patients from mechanical ventilation and its related criteria are of great importance due to the related complications. As there is no comprehensive standard to allocate the time of weaning and due to lack of local research in this field, development of a comprehensive tool to mea...
