Article Synopsis
  • - In utero hematopoietic cell transplantation (IUHCT) takes advantage of the fetus's immune tolerance to successfully introduce donor cells without prior conditioning or immunosuppression, aiming for long-lasting cell integration.
  • - A study injected adult bone marrow cells into fetal mice at gestational ages 12-17 days, finding the highest concentration of donor cells in the brain when injected between GA 13-14, with significant persistence of these cells in the hindbrain.
  • - This research is groundbreaking as it details how donor cells migrate into the nervous system during fetal development, laying the groundwork for using IUHCT to potentially treat neurogenetic disorders.

Background: Phytochemical compounds can modify the rumen microbiome and improve rumen fermentation. This study evaluated the impact of supplementation with tannin and an herbal mixture containing ginger (Zingiber officinale), garlic (Allium sativum), Artemisia (Artemisia vulgaris), and turmeric (Curcuma longa) on the rumen fermentation and microbiota, and histology of rumen tissue of goats. Eighteen Shami male goats were divided into three groups (n = 6): non-supplemented animals fed the basal diet (C, control); animals fed basal diet and supplemented with condensed tannin (T); and animals fed basal diet and supplemented with herbal mixture (HM).

Microalgae-based biodiesel synthesis is currently not commercially viable due to the high costs of culture realizations and low lipid yields. The main objective of the current study was to determine the possibility of growing on yeast wastewater for biodiesel generation at an economical rate. was grown in Guillard F/2 synthetic medium and three dilutions of yeast wastewater (1, 1.

The aim of this research was to investigate zinc chromium ferrite (ZnCrFeO4) nanoparticles, synthesized using the sol gel technique with nanoparticle size controlled through a two-stage annealing process. Stage one was a low temperature firing which produced low quality nanocrystals with an average size of 15 nm. This was followed by a second firing stage at high temperature which enhanced the crystal quality.

We report a young Omani male who developed severe and persistent anaemia after a kidney transplantation while being on immunosuppression therapy, standard practice to prevent rejection of the transplanted kidney. His bone marrow aspirate showed the classic morphological changes of pure red cell aplasia (PRCA), induced by parvovirus B19 infection which is the presence of giant proerythroblasts with viral inclusions. The virus was also demonstrated by polymerase chain reaction in the blood along with IgM antibodies to parvovirus B19.
