An epidemiological study on home injuries among children of 0-14 years in South Delhi.

Background: Injuries are an important public health problem worldwide, accounting for 5 million deaths, of which unintentional injuries account for 0.8 million deaths in children. Though there are many factors responsible for injury in the home, the environment plays an important role.

Sensitive and Specific Guest Recognition through Pyridinium-Modification in Spindle-Like Coordination Containers.

An elaborately designed pyridinium-functionalized octanuclear zinc(II) coordination container 1-Zn was prepared through the self-assembly of Zn , p-tert-butylsulfonylcalix[4]arene, and pyridinium-functionalized angular flexible dicarboxylate linker (H BrL1). The structure was determined by a single-crystal X-ray diffractometer. 1-Zn displays highly sensitive and specific recognition to 2-picolylamine as revealed by drastic blueshifts of the absorption and emission spectra, ascribed to the decrease of intramolecular charge transfer (ICT) character of the container and the occurrence of intermolecular charge transfer between the host and guest molecules.

Monte Carlo and ray tracing algorithms in the cyberknife treatment planning for lung tumours- comparison and validation.

Multiplan treatment planning system, used with Cyberknife system, provides the option of using either the ray tracing algorithm or the Monte Carlo algorithm for the final dose calculation. In order to compare and validate the dose calculations of these algorithms, especially in a heterogeneous medium, a lung phantom study was carried out. Validation has been done with thermoluminiscent dosimetry (TLD) using lithium fluoride rods for the point doses and film dosimetry using EBT2 films for the dose distribution.

A report on anti-oedemogenic activity of Byttneria herbacea roots--possible involvement of histamine receptor (type I).

Ethnopharmacological Relevance: The traditional healers of the Kol tribes of West Bengal, Bihar and Jharkhand (India), widely use the woody rootstock of Byttneria herbacea to reduce the swelling of limbs, due to filariasis. Besides filariasis different part of this plant is used for the treatment of cholera, diarrhoea and asthma.

Aim Of This Study: This study is a preliminary attempt to evaluate the anti-oedemogenic activity of the roots of Byttneria herbacea.

Volumetric modulated arc radiotherapy for esophageal cancer.

A treatment planning study was performed to evaluate the performance of volumetric arc modulation with RapidArc (RA) against 3D conformal radiation therapy (3D-CRT) and conventional intensity-modulated radiation therapy (IMRT) techniques for esophageal cancer. Computed tomgraphy scans of 10 patients were included in the study. 3D-CRT, 4-field IMRT, and single-arc and double-arc RA plans were generated with the aim to spare organs at risk (OAR) and healthy tissue while enforcing highly conformal target coverage.

Chemical and Electrochemical Asymmetric Dihydroxylation of Olefins in I(2)-K(2)CO(3)-K(2)OsO(2)(OH)(4) and I(2)-K(3)PO(4)/K(2)HPO(4)-K(2)OsO(2)(OH)(4) Systems with Sharpless' Ligand.

Iodine-assisted chemical and electrochemical asymmetric dihydroxylation of various olefins in I(2)-K(2)CO(3)-K(2)OsO(2)(OH)(4) and I(2)-K(3)PO(4)/K(2)HPO(4)-K(2)OsO(2)(OH)(4) systems with Sharpless' ligand provided the optically active glycols in excellent isolated yields and high enantiomeric excesses. Iodine (I(2)) was used stoichiometrically for the chemical dihydroxylation, and good results were obtained with nonconjugated olefins in contrast to the case of potassium ferricyanide as a co-oxidant. The potentiality of I(2) as a co-oxidant under stoichiometric conditions has been proven to be effective as an oxidizing mediator in electrolysis systems.
