The expression of CD47 and its association with 2,3-DPG levels in stored leuco-reduced blood units.

Background: Red blood cell (RBC) aging in transfusion medicine is characterized by alteration of many biochemical and morphological integrity of the cell referred to as red cell storage lesion (RCSL), CD47 is a protective marker expressed on RBCs that salvage the cell from phagocytosis. 2,3-diphosphoglycerate (2,3-DPG) tends to have a greater affinity towards deoxygenated hemoglobin. Any oxygen unloading at tissue capillaries are facilitated by 2,3-DPG, and any alterations in its levels can significantly interfere with oxygen release.

Genetic Variation at 15 Autosomal STR Loci Among Seven Egyptian Populations.

Egypt is a transcontinental country containing substantial ethnic, cultural, and linguistic diversity among its people. This study was conducted to investigate the genetic variation at 15 AmpFlSTR Identifiler short tandem repeat (STR) loci, D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818, and FGA, within and between seven Egyptian populations. Samples of 814 unrelated individuals from Northern Coast, Delta, Greater Cairo, Canal governorates, Northern Upper Egypt, Southern Upper Egypt, and Sinai were investigated.

Association of hereditary antithrombin deficiency with intrauterine growth restriction.

: Antithrombin is a major suppressor of thrombin, factor Xa and blood coagulation. Inherited antithrombin deficiency is rare and is considered among the common causes of inherited thrombophilia. The relationship between antithrombin and IUGR, is questionable.

Laser dispersion and ignition of metal fuel particles.

The development of a laser-shock technique for dispersing Al metal fuel particles at velocities approaching those expected in a detonating explosive is discussed. The technique is described in detail by quantifying how air drag affects the temporal variation of the velocity of the dispersed particle plume. The effect of particle size is incorporated by examining various poly-dispersed commercial Al powders at different dispersion velocities (390-630 m/s).

Anatomical closure of trocar site by using tip hole needle and redirecting suture hook.

Background: The incidence of trocar site incisional hernia following laparoscopic surgery is reported to be relatively high. The main reasons are trocar diameter and design, pre-existing fascial defects, and some operation- and patient-related factors. The goal of this article is to present a new procedure for anatomical closure of the trocar site to prevent its herniation.
