Re-emission of slow positrons from tungsten at elevated temperatures by Al-Qaradawi, I. Y.

“…Irrespective of target history, no sharpening of the energy spectrum of re-emitted positrons was observed as the remoderator temperature was increased. Further, a steady decrease in the apparent re-emitted positron intensity was observed, attributed primarily to the increase in positronium formation, as the temperature of the foil was increased from 20 to 500 °C. …”

Profiling of the Differentially Expressed Genes of Inflammation and Angiogenesis of Human Brain Microvascular Endothelial Cells Evoked by Cell Injury In-Vitro to Mimic Acute Ischem... by Al Hamed, Fatima Alzahra Mahmoud

“…Acute IS (AIS) injury of PHBMEC is not well characterized in terms of its consequences on cell functions using genomic function profiling. In our study, we aimed to establish a new model of an acute in-vitro ischemic stroke, within a time limit of 2 hrs., with depriving whole nutrients and not just glucose, under hypoxic condition, in a model we created as oxygen nutrients deprivation (OND). …”

Functional characterization of human myosin-binding protein C3 variants associated with hypertrophic cardiomyopathy reveals exon-specific cardiac phenotypes in zebrafish model by Da'as, Sahar I.

“…MYBPC3 variants genotype–phenotype associations remain poorly understood. We investigated the impact of two novel human MYBPC3 splice-site variants: V1: c.654+2_654+4dupTGG targeting exon 5 using morpholino MOe5i5; and V2: c.772+1G'A targeting exon 6 using MOe6i6; located within C1 domain of cMyBP-C protein, known to be critical in regulating sarcomere structure and contractility. …”

Sanguinarine Induces Apoptosis Pathway in Multiple Myeloma Cell Lines via Inhibition of the JaK2/STAT3 Signaling. by Akhtar, Sabah

“…The SNG-mediated apoptosis appears to be resulted from suppression of the constitutively active STAT3 with a concomitant increase in expression of protein tyrosine phosphatase (SHP-1). SNG treatment of MM cells leads to down-regulation of the anti-apoptotic proteins including cyclin D, Bcl-2, Bclxl, and XIAP. …”
