Molecular precursor-mediated facile synthesis of photo-responsive stibnite SbS nanorods and tetrahedrite CuSbS nanocrystals.

Stibnite SbS and tetrahedrite CuSbS nanostructures being economical, environmentally benign and having a high absorption coefficient are highly promising materials for energy conversion applications. However, producing these materials especially tetrahedrite in the phase pure form is a challenging task. In this report we present a structurally characterized single source molecular precursor [Sb(4,6-MepymS)] for the facile synthesis of binary SbS as well as ternary CuSbS in oleylamine (OAm) at a relatively lower temperature.

Role of vascular endothelial growth factor (VEGF) in the neurological manifestations of dengue: a preliminary study.

This study reports on vascular endothelial growth factor (VEGF) in dengue patients with neurological manifestations. Their bleeding diathesis, hypotension, edema, flushing, and hepatosplenomegaly were noted. Complete blood counts, serum chemistry, coagulation profile, liver and kidney function tests, creatine kinase (CK), and MRI in encephalopathic patients were carried out.

Vascular endothelial growth factor in tuberculous meningitis.

Vascular endothelial growth factor (VEGF) is linked to brain edema and infarction, but there is paucity of studies correlating VEGF level with magnetic resonance imaging (MRI) changes in tuberculous meningitis (TBM). The aim of this study was to measure serum VEGF level in TBM and correlate it with clinical, laboratory, and MRI findings. Forty patients with TBM underwent cranial evaluation, cranial MRI, and MR angiography (MRA).
