Similar to other forms of non-transfusion-dependent thalassemia, the diagnosis of β-thalassemia intermedia is associated with a state of iron overload. This occurs in the absence of regular transfusion therapy and is primarily attributed to increased intestinal iron absorption signaled by ineffective erythropoiesis and low serum hepcidin levels. Although iron accumulation in transfusion-indepen...

INTRODUCTION The influx and efflux of military personnel in the possible endemic areas of leishmaniasis provided the impetus for research on the sandflies on Marambaia Island. METHODS Sandflies were collected with light traps installed in the 3 ecotypes of 3 areas chosen for their particular landscape aspects. RESULTS In 2009, were collected 32,006 specimens of sandflies belonging to 13 spe...

Although the life expectancy of thalassemia patients has markedly improved over the last few decades, patients still suffer from many complications of this congenital disease. The presence of a high incidence of thromboembolic events, mainly in thalassemia intermedia, has led to the identification of a hypercoagulable state in these patients. In this review, the molecular and cellular mechanism...

Our understanding of the molecular and pathophysiological mechanisms underlying the disease process in patients with b-thalassemia intermedia has substantially increased over the past decade. Earlier studies observed that patients with b-thalassemia intermedia experience a clinical-complications profile that is different from that in patients with b-thalassemia major. In this article, a variety...

Two new phenols, 2(S)-2',7-dihydroxy-5,8-dimethoxyflavanone and (S)-2-(4-hydroxyphenyl)-6-methyl-2,3-dihydro-4H-pyran-4-one, were isolated from the ethanol extract of Scutellaria barbata. Their structures were elucidated on the basis of spectroscopic analysis.

The precipitin test was applied to identify the blood meal sources of Lutzomyia intermedia, collected in two distinct habitats: inside houses and in the peridomicile, in Mesquita, Rio de Janeiro State, Brazil, a transmission area of Leishmania (V.) braziliensis. The following antisera were tested: human, avian, equine, rodent, and opossum. From a total of 370 females analyzed, 128 specimens fro...

The use of biological responses to contaminant exposure by lichen species has become a useful tool in environmental quality evaluation and risk assesment. Lichen Hypogymnia physodes and Usnea hirta samples were collected in 2006 from 10 sites around iron-steel factory in Karabük, Turkey. H. physodes and U. hirta samples from Yenice forest were used as a control. The aim of present study was to ...

Thalassemia is a congenital hemolytic anemia prevalent in Asian and Mediterranean races. The homozygous state results in thalassemia major or Cooley's anemia, and such patients are transfusion-dependent. A less severe syndrome, thalassemia intermedia, may be due to compound heterozygosity for /3-thalassemia and /3 variant (e.g., hemoglobin E [HbE]) genes and is characterized by anemia, jaundice...
