Successful Intra-peritoneal Antibiotic Therapy for Primary Abdominal Nocardiosis in an Immunocompetent Young Female Masquerading as Carcinoma Ovary

Nocardiosis is a common opportunistic infection in the immunocompromised and in patients with chronic debilitating diseases,e.g continuous ambulatory peritoneal dialysis (CAPD) patients. Primary abdominal nocardiosis is rare and is indeed a very rare infection in immunocompetent persons. Only two cases have been reported in immunocompetent patients so far and this may be third case to the best of our knowledge and first in India. About 11 cases have been reported in CAPD patients and AIDS patients.We report a case of Nocardiosis in an immunocompetent young female who presented with an abdomino-pelvic mass masquerading as carcinoma ovary.After initial resistance to various antibiotics, she responded to intraperitoneal and oral linezolid and oral ciprofloxacin

1-Benzoyl-3-(2,4,5-trichloro­phen­yl)thio­urea

The benzene and phenyl rings in the title compound, C14H9Cl3N2OS, form a dihedral angle of 40.98 (6)°. The mol­ecule exists in the thione form with typical thio­urea C—S [1.666 (2) Å] and C—O [1.227 (3) Å] bond lengths as well as shortened C—N bonds [1.345 (3) and 1.386 (2) Å]. An intra­molecular N—H⋯O hydrogen bond stabilizes the mol­ecular conformation. In the crystal, pairs of N—H⋯S hydrogen bonds link the mol­ecules into centrosymmetric dimers

Scopolamine Administration Modulates Muscarinic, Nicotinic and NMDA Receptor Systems

Studies on the effect of scopolamine on memory are abundant but so far only regulation of the muscarinic receptor (M1) has been reported. We hypothesized that levels of other cholinergic brain receptors as the nicotinic receptors and the N-methyl-D-aspartate (NMDA) receptor, known to be involved in memory formation, would be modified by scopolamine administration

A uracil nitroso amine based colorimetric sensor for the detection of Cu2+ ions from aqueous environment and its practical applications

A simple uracil nitroso amine based colorimetric chemosensor (UNA-1) has been synthesized and screened for its cation recognition ability. Sensor UNA-1 exhibited a high sensitivity and selectivity towards Cu2+ ions in aqueous medium in the presence of a wide range of other competing cations (Ag+, Al3+, Ba2+, Ca2+, Cd2+, Co2+, Cr3+, Cs+, Fe2+, Fe3+, Li+, Mg2+, Mn2+, Na+, Ni2+, Pb2+, Zn2+, Hg2+ and Sr2+). With Cu2+, the sensor UNA-1 gave a distinct color change from colorless to dark yellow by forming a complex of 1 : 1 stoichiometry. Furthermore, sensor UNA-1 was successfully utilized in the preparation of test strips and supported silica for the detection of Cu2+ ions from aqueous environment.A simple uracil nitroso amine based colorimetric chemosensor (UNA-1) has been synthesized and screened for its cation recognition ability.

Bias-Modified Schottky Barrier Height-Dependent Graphene/ReSe2 van der Waals Heterostructures for Excellent Photodetector and NO2 Gas Sensing Applications

Herein, we reported a unique photo device consisting of monolayer graphene and a few-layer rhenium diselenide (ReSe2) heterojunction. The prepared Gr/ReSe2-HS demonstrated an excellent mobility of 380 cm2/Vs, current on/off ratio ~ 104, photoresponsivity (R ~ 74 AW−1 @ 82 mW cm−2), detectivity (D* ~ 1.25 × 1011 Jones), external quantum efficiency (EQE ~ 173%) and rapid photoresponse (rise/fall time ~ 75/3 µs) significantly higher to an individual ReSe2 device (mobility = 36 cm2 V−1s−1, Ion/Ioff ratio = 1.4 × 105–1.8 × 105, R = 11.2 AW−1, D* = 1.02 × 1010, EQE ~ 26.1%, rise/fall time = 2.37/5.03 s). Additionally, gate-bias dependent Schottky barrier height (SBH) estimation for individual ReSe2 (45 meV at Vbg = 40 V) and Gr/ReSe2-HS (9.02 meV at Vbg = 40 V) revealed a low value for the heterostructure, confirming dry transfer technique to be successful in fabricating an interfacial defects-free junction. In addition, HS is fully capable to demonstrate an excellent gas sensing response with rapid response/recovery time (39/126 s for NO2 at 200 ppb) and is operational at room temperature (26.85 °C). The proposed Gr/ReSe2-HS is capable of demonstrating excellent electro-optical, as well as gas sensing, performance simultaneously and, therefore, can be used as a building block to fabricate next-generation photodetectors and gas sensors
