Thioredoxins (Trxs) are small ubiquitous oxidoreductase proteins with two redox-active Cys residues in a conserved active site (WCG/PPC) that regulate numerous target proteins via thiol/disulfide exchanges in the cells of prokaryotes and eukaryotes. The isoforms OsTrx23 with a typical active site (WCGPC) and OsTrx20 with an atypical active site (WCTPC) are two  Trx h- type isoforms in rice that ...

Uterine rupture often occurs in the third trimester of pregnancy or during labor. Its occurrence in early pregnancy and in the absence of any predisposing factors is very rare. Untimely diagnosis and a low index of suspicion could be life-threatening. Here we report the case of a 29-year-old woman with a history of two previous cesarean sections. An ultrasound report revealed a dead fetus in th...

We investigated the effects of postfire salvage logging on cavity-nesting birds by comparing nest densities and patterns of nest reuse over a three-year period in seven logged and eight unlogged patches of mixed-conifer forest in the Blackfoot-Clearwater Wildlife Management Area, Montana. We found 563 active nests of 18 cavity-nesting birds; all species were found nesting in the uncut burned fo...

Optical power flow along an active cavity having net gain can differ dramatically from that in a passive cavity. We report the first observation of Poynting’s vector reversal in an active cavity under scattering boundary conditions. At a sub-lasing gain, which we call Poynting’s threshold, a null develops in Poynting’s vector, which divides the cavity into sections with oppositely directed ener...

The molecular function of a protein is coupled to the binding of a substrate or an endogenous ligand to a well defined binding cavity. To detect functional relationships among proteins, their binding-site exposed physicochemical characteristics were described by assigning generic pseudocenters to the functional groups of the amino acids flanking a particular active site. These pseudocenters wer...

A 52-y-old man presenting with dyspnea and a massive effusion in the right pleural cavity underwent wedge biopsies of pulmonary lesions found on thoracic CT, leading to a diagnosis of pleural angiosarcoma. Bleeding developed postoperatively and was investigated using pulmonary CT angiography, which failed to identify a site of active bleeding. (99m)Tc-labeled red blood cell (RBC) SPECT/CT of th...

Leiomyoma of nasal cavity is a rare and benign tumor of smooth muscle origin that uncommonly arises from the nasal septum. We present an unusual case of histopathologically diagnosed locally extensive leiomyoma of the nasal septum which was clinically and radiologically misdiagnosed as malignancy of the nasal cavity. This case report emphasizes the rare occurrence of this entity at this site an...

The frequency of cavity reoccupation in secondary cavity nesters depends on several factors including quality of cavities, degree of nest-site fidelity, competition with other cavity nesters and availability of new cavities. Blue-fronted Parrots Amazona aestiva are secondary cavity nesters that live in subtropical forests and savannas of central South America. We examined the characteristics of...

A cluster model for active site of nanotube (C48) was presented and investigated the geometricstructure and thermochemical parameters. Quantum-mechanical calculations were performed at theHF / 510-30, 6-310, 6-3 IG• and 6-310" levels of theory in the gas phase and three solvents atfour temperatures. Also, nuclear shielding parameters of the active site of nanotube have been takeninto account us...
