Obesity and vitamin D deficiency represent major health problems among Saudi children, and have been linked to chronic diseases. Obese children are at risk of developing vitamin D deficiency, which appears to have negative influences on energy homeostasis, impeded bone mineralisation, insulin resistance and inflammation. Evidence supporting the association between vitamin D deficiency of obese ...

Antibody diversification in IgM and IgG antibodies was analyzed in an 18-month old bovine (Bos taurus) suffering from naturally occurring chronic and recurrent infections due to bovine leukocyte adhesion deficiency (BLAD). The BLAD, involving impaired leukocyte beta2 integrin expression on leukocytes, develops due to a single point mutation in conserved region of the CD18 gene resulting in subs...

Integrin activation is essential for the function of leukocytes. Impaired integrin activation on leukocytes is the hallmark of the leukocyte adhesion deficiency syndrome in humans, characterized by impaired leukocyte recruitment and recurrent infections. In inflammation, leukocytes collect different signals during the contact with the microvasculature, which activate signaling pathways leading ...

BACKGROUND/AIMS Longtime chronic malabsorption may among other things cause a lack of liposoluble vitamins. Vitamin E deficiency can lead to formation of lipofuscin aggregates. Its deficiency is also associated with an increased lipofuscinosis of the bowel, i.e. brown bowel syndrome. METHODS Systematic research via Medline on brown bowel syndrome, lipofuscinosis, and vitamin E deficiency was ...

Foamy virus (FV) vectors have shown great promise for hematopoietic stem cell (HSC) gene therapy. Their ability to efficiently deliver transgenes to multi-lineage long-term repopulating cells in large animal models suggests they will be effective for several human hematopoietic diseases. Here, we review FV vector studies in large animal models, including the use of FV vectors with the mutant O...

BACKGROUND Mutations in the dedicator of cytokinesis 8 gene (DOCK8) cause a combined primary immunodeficiency syndrome that is characterized by elevated serum IgE levels, depressed IgM levels, eosinophilia, sinopulmonary infections, cutaneous viral infections, and lymphopenia. Many patients with DOCK8 deficiency were previously thought to have a variant of Job's syndrome. Distinguishing between...

Autosomal deletion syndromes are of great interest since measurable loss of genetic material could lead to the mapping of the human autosomes. Short arm deletions and long arm deletions of chromosome 18 have been described in association with phenotypic changes (Grouchy et al., 1963, 1964) and reviewed recently by Wolf et al. (1967) and Reinwein, Ritter, and Wolf (1967). Since a ring chromosome...

This study was designed to evaluate vitamin D3 and metabolic hormones in hypothyroidism with syndrome without syndrome. Sixty patients were divided into three groups, 30 syndrome, healthy controls compared the patients. There a significant increase tetraiodothyronine, free thyronine very thyroid stimulating hormone women A systolic blood pressure, body mass index, fasting glucose, glycosylated ...
