Seven lichens (Usnea antarctica and U. aurantiacoatra) and nine moss samples (Sanionia uncinata) collected in King George Island were analyzed using instrumental neutron activation analysis, and concentration of major and trace elements was calculated. For some elements, the concentrations observed in moss samples were higher than corresponding values reported from other sites in the Antarctica...

The pars intermedia of teleosts contains two types of granular cells with the predominant type being similar to the pars intermedia cells in other vertebrate groups and containing peptides derived from the pro-opiomelanocortin precursor molecule. The function and products of the second cell type, the PAS positive cells, are unknown. This study reports on the identification of biosynthetic produ...

Periodontitis is an inflammatory disease of the supporting structures of the teeth caused by, among other pathogens, Prevotella intermedia. Many strains of P. intermedia are resistant to killing by the human complement system, which is present at up to 70% of serum concentration in gingival crevicular fluid. Incubation of human serum with recombinant cysteine protease of P. intermedia (interpai...

BACKGROUND Heart disease is the main cause of mortality and morbidity in patients with beta thalassemia, rendering its early diagnosis vital. We studied and compared echocardiographic findings in patients with beta thalassemia major, patients with beta thalassemia intermedia, and a control group. METHODS Eighty asymptomatic patients with thalassemia major and 22 asymptomatic cases with thalas...

introduction: thalassemia is common in iran. appropriate therapy for this disease includes a regular blood transfusion and chelation therapy. however, patients will inevitably confront with side effects, particularly iron overloads in critical organ including heart, ductless glands and liver. this study tries to determine the prevalence of diabetes mellitus in transfusion dependent β thalassemi...

Atranorin 1, Usnic acid 2, and D-Arabinitol 3 were isolated from Usnea aciculifera by extensive column chromatography. The structures elucidated based on the comprehensive spectral analysis including FT IR, GC MS, ESI 13C NMR, 1H NMR. compounds evaluated for their cytotoxic activity against LN-229 glioblastoma cancer cell line performing Sulforhodamine B assay (SRB). 2 showed strong with an IC5...

this study presented a mini review on folic acid deficiency and recommendations for its supplementation in thalassemia intermedia (ti). ti is a clinical condition which lies between thalassemia major and thalassemia minor. although ti patients may not need regular blood transfusion, precise diagnosis and management are critical for the prevention of clinical complications and quality of life im...

background: cardiac dysfunction due to chronic anemia and hemosiderosis are the major causes of death among patients with thalassemia intermedia. this study was performed to compare the cardiac function in thalassemia intermedia patients with normal subjects by means of echocardiography. materials and methods: this was a case-control study performed on 22 patients affected by thalassemia interm...
