Abstract Introduction Circadian factors may contribute to sleep difficulties among chronic insomnia disorder (CID) patients who do not otherwise meet full criteria for a circadian rhythm sleep-wake disorder, particularly delayed and advanced phase disorders. Current nosology suggests that using preference measures can provide important diagnostic information aid in differential diagnosis. Howev...

abstract objective cardiac dysfunction is a major cause of death in patients with beta thalassemia. in these patients, repeated blood transfusion, ineffective erythropoiesis and increased gastrointestinal iron absorption lead to iron overload in the body and this induced heart failure. left ventricular ejection fraction was measured in major beta thalassemia (β-th) patients to detect the relati...

objective: helicobacter pylori has a well-established role in the development of gastric cancer. in vitro studies reveal increased proliferation of the gastric mucosa in the presence of h. pylori infection. it has been also shown that production of some cytokines, such as interleukin-1 beta (il-1b) is increased in h. pylori infection. in addition, il-1b increases proliferation of gastric epithe...

Natural kaolinite was subjected to a successful exfoliation process into separated nanosheets (KNs), followed by hybridization with β-cyclodextrin biopolymer (β-CD), forming an advanced bio-nanocomposite (β-CD/KNs). The synthetic products were evaluated as enhanced delivery structures for oxaliplatin chemotherapy (OXAPN). of KNs β-CD polymer notably the loading capacity 355.3 mg/g (β-CD/KNs) co...

the presence of antibacterial activity in bovine β-lactoglobulin and in α-lactalbumin hydrolysates was investigated. the plasmin-digest of β-lactoglobulin (pdβ) and of α-lactalbumin (pdα) were fractionated, using reversed phase high performance liquid chromatography. the antibacterial activity of β-lactoglobulin, α-lactalbumin, nisin, plasmin, pdβ and pdα were in vitro tested against pathogenic...

background: β-thalassemia is an autosomal hemoglobinopathy with inconsistent universal distribution. among patients with thalassemia diverse non-siderotic complications distinctly influence the attribute of life, including zinc deficiency due to varied etiologies. the objective of the present study was to determine zinc levels in patients with β-thalassemia major and its correlation with matern...

hemoglobin f (hbf, α 2 γ 2 ) is a major contributor to the clinical heterogeneity and ameliorating agent observed in patients with the β-globin disorders including β-thalassemia and sickle cell disease (scd). during fetal life, hbf is the major hemoglobin but is largely substituted by adult hemoglobin (hba, α 2 β 2 ) following a globin expression switch after birth. increased γ-globin expressio...

background: in the previous study, we have shown that the presence of a allele at position -588 in aγ-globin gene was highly frequent and closely associated with fetal hemoglobin elevation among β-thalassemia intermedia patients. therefore, we decided to investigate whether this allele (a allele at -588) could result in an increase in aγ-globin gene expression to ameliorate the severity of the ...
