abstract   background : the application of du emanation for first time contaminated certain areas in the south west region of iraq after the second gulf war (1991). these contaminated areas were discovered in 1994. radioactive contamination was detected using the nuclear enterprise pcm5/1 in soil samples collected from two regions near by grazing lands. this study was done for assessment of du ...

Abstract Staphylococcal bacteria are a common cause of skin infections in mice and humans. γδ T cells the cytokine IL-17 important controlling these infections. To test roles for autoimmune Ets1 knockout (KO) mice, we generated double (DKO) lacking both IL-17RA. We found that DKO develop worse disease than KO also susceptible to spontaneous Staphylococcus xylosus While IL-17RA lesions, lesions ...

Studies were conducted to explore in rats the role of retinol in the regulation of the synthesis and secretion of retinol-binding protein (RBP) by the visceral yolk sac compared to the liver. Previous studies have shown that in retinol deficiency, hepatic RBP secretion is specifically inhibited, whereas hepatic RBP synthesis rate is unchanged. Retinol-depleted, retinoic acid-supplemented female...

Locus control regions are regulatory elements that activate distant genes and typically consist of several DNase I hypersensitive sites coincident with clusters of transcription activator binding sites. To what extent nucleosomes and activators occupy these sites together or exclusively has not been extensively studied in vivo. We analyzed the chromatin structure of human beta-globin locus cont...

Normal rat kidney cells were cultured in medium supplemented with normal fetal bovine serum (FBS) or FBS depleted of fibronectin. The cell surface fibronectin of these cultures was visualized by indirect immunofluorescence using species-specific antisera for either rat fibronectin or bovine fibronectin. Anti-rat-fibronectin revealed fibrillar structures on the cells grown in either normal mediu...

BACKGROUND Thymus organogenesis and T lymphocyte development are accomplished together during fetal life. Proper development and maintenance of thymus architecture depend on signals generated by a sustained crosstalk between developing thymocytes and stromal elements. Any maturation impairment occurring in either cellular component leads to an aberrant thymic development. Gene expression occurr...

background: in most cancer cases, the treatment choice for a pregnant patient is radiotherapy. in these patients, the abdomen is usually not exposed therefore fetus exposure is due to peripheral dose (pd). the purpose of this study was to estimate the fetal dose (the maximum pd in each pregnancy stage) for modalities available and to fabricate and evaluate a generally applicable fetal shield. m...

Preeclampsia is characterized by reduced placental perfusion with placental ischemia and hypertension during pregnancy. Preeclamptic women also exhibit a heightened inflammatory state and greater number of neutrophils in the vasculature compared to normal pregnancy. Since neutrophils are associated with tissue injury and inflammation, we hypothesized that neutrophils are critical to placental i...
