Normalize the response of electronic portal imaging device (EPID) is the first step toward an EPID-based standardization of Linear Accelerator (linac) dosimetry quality assurance. In this study, we described an approach to generate two-dimensional (2D) pixel sensitivity maps (PSM) for EPIDs response normalization utilizing an alternative beam and dark-field (ABDF) image acquisition technique an...

OBJECTIVE To prospectively examine the effects of the margin status after radical prostatectomy (RP), the location, and the number of positive surgical margins (PSMs) on biochemical and clinical outcome, as even if there seems to be little debate that there is a higher risk of both local and distant recurrence of prostate cancer in the face of a PSM the significance of a PSM after RP is only fo...

Psychological stress has been implicated as a cause of several psychosomatic disorders, but also as a factor that can unfavourably influence many diseases including diabetes mellitus. Measure of psychological stress in diabetes was performed by Psychological Stress Measure (PSM), a validated instrument, designed using 49 items drawn from descriptors generated by focus groups on stress. Clinical...

During somitogenesis, pairs of epithelial somites form in a progressive manner, budding off from the anterior end of the pre-somitic mesoderm (PSM) with a strict species-specific periodicity. The periodicity of the process is regulated by a molecular oscillator, known as the "segmentation clock," acting in the PSM cells. This clock drives the oscillatory patterns of gene expression across the P...

Oral microbiota contribute to health and disease, and their disruption may influence the course of oral diseases. Here, we used pyrosequencing to characterize the oral bacteriome and mycobiome of 12 HIV-infected patients and matched 12 uninfected controls. The number of bacterial and fungal genera in individuals ranged between 8-14 and 1-9, among uninfected and HIV-infected participants, respec...

Rangelands throughout the world contain varying but often substantial proportions of shrubs. Shrubs are generally heavily chemically defended, and herbivores must either contend with their plant secondary metabolites (PSM) or avoid a significant component of the available forage. Browsing ruminants are exposed to thousands of chemicals in infinite combinations and concentrations that are consta...

Two immunochemically distinct mucins have been isolated from pig submaxillary glands. The glands were combined according to the ability of aqueous extracts of these glands to inhibit hemagglutination of human type A erythrocytes. Mucin isolated from the glands containing blood group A activity is designated A+ pig submaxillary mucin (A+-PSM), while mucin isolated from the remaining glands is de...

Nowadays Wi-Fi is the most mature technology for wireless-Internet access. Despite the large (and ever increasing) diffusion of Wi-Fi hotspots, energy limitations of mobile devices are still an issue. To deal with this, the standard 802.11 includes a Power-Saving Mode (PSM), but not much attention has been devoted by the research community to understand its performance in depth. We think that t...

Bacterial virulence and antibiotic resistance have a significant influence on disease severity and treatment options during bacterial infections. Frequently, the underlying genetic determinants are encoded on mobile genetic elements (MGEs). In the leading human pathogen Staphylococcus aureus, MGEs that contain antibiotic resistance genes commonly do not contain genes for virulence determinants....

BACKGROUND Soy milk (SM) and its fermented products are identified as rich sources of bioactive compounds helping to manage and to reduce the risk of chronic disease. This study aimed to compare the effects of SM and probiotic SM (PSM) consumption on serum low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) in diabetic Wistar rats. METHODS Probiotic SM...
