Although the combination of immune checkpoint blockades with high dose radiation has indicated potential co-stimulatory effects, consistent clinical outcome been yet to be demonstrated. Bulky tumors present challenges for treatment achieve rate tumor control due large sizes and normal tissue toxicities. As an alternative, spatially fractionated radiotherapy (SFRT) technique applied, in forms GRID or LATTICE therapy (LRT), safely treat bulky tumors. When used alone a single few fractions, LRT...

Clinical microbiology laboratories have to accurately identify clinical microbes. However, there can be failure in the identification of certain bacteria or fungi by phenotypic criteria sometimes. Therefore, ability 16S ribosomal DNA (16S rDNA) and internal transcribed spacer 2 (ITS2) sequencing these "difficult-to-identify" was assessed this study. Samples obtained from a teaching hospital over past three years were examined. The rDNA four standard strains, 18 common isolates, 47 amplified...

Abstract Hypertension is a leading risk factor for disease burden worldwide. Vascular contraction and remodeling contribute to the development of hypertension. Glutathione S-transferase P1 (Gstp1) plays several critical roles in both normal neoplastic cells. In this study, we investigated effect Gstp1 on hypertension as well vascular smooth muscle cell (VSMC) phenotypic switching. We identified higher level arteries VSMCs from hypertensive rats compared with normotensive first time. then...
