An improved method of water electrolysis – effect of complexing agent

The present work investigates the efficiency of an alkaline water electrolysis process in the presence of a complexing agent like citric acid (CA) when added directly into the electrolyte during the electrolytic process. High surface area nickel electrodes prepared by electrodeposition technique were used as the electrode to evaluate the efficiency of the oxygen evolution reaction (OER) by the polarization measurements and cyclic voltammetry. The quantity of the complexing agent CA in the electrolyte was varied from 0-1 wt. %. An increase in the current density of about 25 % resulted at a temperature of 30 °C in the presence of 0.2 wt. % of CA at 1.0 V vs. Hg/HgO. CA was found to improve performance by forming a complex with the alloy electrode and by formation of the high surface area catalyst for efficient OER

Villoglandular papillary adenocarcinoma of the uterine cervix with lymph node metastasis - A case report and review of the literature

Villoglandular papillary adenocarcinoma was first described by Young and Scully in 1989 as a distinct entity with the histological features of exophytic growth proliferation, villous and papillary architecture and mild to moderate nuclear atypia. We report one case of villoglandular papillary adenocarcinoma (VGPA) of the uterine cervix with lymph node metastasis and reviewed the clinicopathological features of six other cases reported in the literature. Our patient is the seventh similar reported cases. They ranged in age from 29 to 54 (mean, 41) years. Five had lymphovascular invasion. All except our patient were treated with radical hysterectomy and radiotherapy. She was followed-up for 7 months and unfortunately died due to chest infectio

1-Methyl-3-(naphthalen-1-yl)-3,3a,4,9b-tetra­hydro-1H-chromeno[4,3-c]isoxazole-3a-carbonitrile

In the title compound, C22H18N2O2, the pyran ring of the chromene unit is fused with an isoxazole ring, which adopts an N-envelope conformation with the N atom lying 1.3291 (14) Å from the mean plane of the remaining ring atoms [maximum deviation = 0.341 (2) Å]. The dihedral angle between the isoxazole and chromene units is 43.74 (8)° and that between the iosxazole ring and the naphthalene ring system is 58.82 (8)°. In the crystal, the molecules are linked by weak C—H⋯π inter­actions

Broad and potent cross clade neutralizing antibodies with multiple specificities in the plasma of HIV-1 subtype C infected individuals.

Broadly Cross clade Neutralizing (BCN) antibodies are recognized as potential therapeutic tools and leads for the design of a vaccine that can protect human beings against various clades of Human Immunodeficiency Virus (HIV). In the present study, we screened plasma of 88 HIV-1 infected ART naïve individuals for their neutralization potential using a standard panel of 18 pseudoviruses belonging to different subtypes and different levels of neutralization. We identified 12 samples with good breadth of neutralization (neutralized >90% of the viruses). Four of these samples neutralized even the difficult-to-neutralize tier-3 pseudoviruses with great potency (GMT > 600). Analysis of neutralization specificities indicated that four samples had antibodies with multiple epitope binding specificities, viz. CD4-binding site (CD4BS), glycans in the V1/V2 and V3 regions and membrane proximal external region (MPER). Our findings indicate the strong possibility of identifying highly potent bNAbs with known or novel specificities from HIV-1 subtype C infected individuals from India that can be exploited as therapeutic tools or lead molecules for the identification of potential epitopes for design of a protective HIV-1 vaccine

Methyl (2Z)-2-bromomethyl-3-(3-chlorophenyl)prop-2-enoate

There are two independent molecules (A and B) in the asymmetric unit of the title compound C11H10BrClO2, which represents the Z isomer. The methylacrylate moieties are essentially planar, within 0.084 (2) and 0.027 (5) Å in molecules A and B, respectively. The benzene ring makes dihedral angles of 13.17 (7) and 27.89 (9)° with the methylacrylate moiety in molecules A and B, respectively. The methylbromide moiety is almost orthogonal to the benzene ring, making dihedral angles of 81.46 (16)° in molecule A and 79.61 (16)° in molecule B. The methylacrylate moiety exhibits an extended trans conformation in both molecules. In the crystal, pairs of C—H...O hydrogen bonds result in the formation of quasi-centrosymmetric R22(14) AB dimers
