Isolation and characterization of a blue coloured three coordinate Cu(I)-radical complex with an S donor set.

A stable three coordinate Cu(I)-radical complex with an S donor set having the general formula of [Cu(S-NHCH)(SS-NHCS)] (1) was isolated as dark blue needles. Interestingly, this complex possesses a zwitterionic ligand, S-NHCH, which is coordinated to the central Cu(I) ion its S-atom [S-NHCH C4-thiolate functionalized C2-protonated zwitterionic N-hetero cyclic carbene; SS-NHCS˙ NHC-based dithiolene radical anion]. 1 has been structurally characterized by single-crystal X-ray diffraction, and further characterized by UV-vis, IR, XPS, and EPR spectroscopy.

A prospective observational study to assess the epidemiological profile of multiple primary cancers in Eastern India.

Background: Multiple primary cancers once thought to be rare have become increasingly common as the lifespan of cancer survivors has increased with availability of better and more effective cancer treatment. However, their exact incidence is not known and data on their epidemiological characteristics are not available.

Aim: The aim of this study is to study the epidemiologic characteristics of multiple primary cancers in the eastern region of India.

Acid hydrolysis conditions for quantification of meningococcal X polysaccharide in a pentavalent vaccine using HPAEC-PAD/ESI-MS.

A selective and sensitive method was evaluated for quantitation of meningococcal X (Men X) polysaccharide in pentavalent meningococcal A, C, W, Y and X conjugate vaccine using different acid hydrolysis conditions like HCl, TFA, HF, HF-TFA, and HF-HCl. High-performance anion exchange chromatography with pulsed amperometric detection (HPAEC-PAD) using CarboPac PA10 column was used to identify the hydrolyzed products based on retention time and its comparison with monosaccharide standards. Complete release of glucosamine (GlcN) from Men X in monovalent bulk and pentavalent vaccine samples was achieved using HF hydrolysis at 80 °C for 2 h.

Quantitation of free cyanide using ion exchange chromatography in Neisseria meningitidis serogroups A, C, W, Y and X conjugates used in vaccine manufacture.

Polysaccharide vaccines essentially used in the prevention of bacterial infections are known to be good immunogens when conjugated to an immunogenic protein using various cyanylating agents. Analysis of residual cyanide in polysaccharide conjugate vaccines is an ardent task due to the complexity of the sample matrices and the lack of suitable methods. We report a selective ion chromatography method with electrochemical detection using IonPac AS7 column for estimation of residual cyanide in meningococcal serogroups A, C, W, Y and X bulk conjugates in presence of other interfering ions.

Antibiotic-resistant in deer and nearby water sources at Safari parks in Bangladesh.

Background And Aim: The emergence and rapid dissemination of multidrug-resistant (MDR) bacteria in different ecosystems is a growing concern to human health, animal health, and the environment in recent years. The study aimed to determine the antibiotic resistance in from deer and nearby water sources at two different Safari parks in Bangladesh.

Materials And Methods: A number of 55 fresh fecal samples of deer and six water samples from nearby lakes were collected from two Safari parks.

Antibiotic resistance of isolated from captive Bengal tigers at Safari parks in Bangladesh.

Objectives: The present study was carried out to assess the antibiotic resistance and to identify the resistance genes in from captive Bengal tigers at two Safari parks in Bangladesh.

Materials And Methods: A number of 24 environmental fecal swab samples of Bengal tigers were collected from two different Safari parks in Bangladesh. For the isolation of , samples were submitted to a number of bacteriological screening and biochemical tests.

Collaborative efforts to forecast seasonal influenza in the United States, 2015-2016.

Since 2013, the Centers for Disease Control and Prevention (CDC) has hosted an annual influenza season forecasting challenge. The 2015-2016 challenge consisted of weekly probabilistic forecasts of multiple targets, including fourteen models submitted by eleven teams. Forecast skill was evaluated using a modified logarithmic score.

Pattern of Failure with Locally Advanced Cervical Cancer– A Retrospective Audit and Analysis of Contributory Factors.

Background: The majority of the global burden of cervical cancer is affecting developing countries. Despite improvement in treatment of patients presenting at a locally advanced stage, approximately 50% experience recurrence within the 1st two years. This study was conducted to analyse contributory factors for recurrence within 24 months.

Extracalvarial Meningioma in the Parapharyngeal Space: Presentation, Diagnosis and Management.

Extracalvarial meningioma in the cervical region presenting as a parapharyngeal mass lesion is seldom encountered in clinical practice and poses great challenge in its diagnosis and surgical management. In this report, we present a case of extracranial meningioma in a middle-aged person who presented with a large, gradually progressing cervical swelling with multiple cranial nerve pareses. The difficulties in diagnosis and surgical management of this unusual neoplasm in the setting of partial encasement and thrombosis of the internal jugular vein have been discussed, along with the computed tomography and magnetic resonance imaging providing details of its extent and character.

Temporal Topic Modeling to Assess Associations between News Trends and Infectious Disease Outbreaks.

In retrospective assessments, internet news reports have been shown to capture early reports of unknown infectious disease transmission prior to official laboratory confirmation. In general, media interest and reporting peaks and wanes during the course of an outbreak. In this study, we quantify the extent to which media interest during infectious disease outbreaks is indicative of trends of reported incidence.

Multi technique amalgamation for enhanced information identification with content based image data.

Image data has emerged as a resourceful foundation for information with proliferation of image capturing devices and social media. Diverse applications of images in areas including biomedicine, military, commerce, education have resulted in huge image repositories. Semantically analogous images can be fruitfully recognized by means of content based image identification.

An adaptive differential evolution algorithm with novel mutation and crossover strategies for global numerical optimization.

Differential evolution (DE) is one of the most powerful stochastic real parameter optimizers of current interest. In this paper, we propose a new mutation strategy, a fitness-induced parent selection scheme for the binomial crossover of DE, and a simple but effective scheme of adapting two of its most important control parameters with an objective of achieving improved performance. The new mutation operator, which we call DE/current-to-gr_best/1, is a variant of the classical DE/current-to-best/1 scheme.

Spectrum of congenital surgical malformations in newborns.

A prospective study to detect the frequency and distribution of congenital surgical malformations in a rural hospital setting in Maharashtra was carried out. A total of 3000 consecutive births over a 9-month period was included and the frequency of congenital malformations was 21.1 per 1000 births.
