Benign and malignant bone tumors arise in small bones of the hands and feet. Nevertheless, secondary deposits at these sites are extremely rare. We report a peculiar case of an adult man who presented with thumb swelling, which was later discovered to be a metastasis from renal cell carcinoma. Such cases have a sinister prognosis with a survival ra...

TRAFFIC, the Turtle Survival Alliance India (TSA-India) and WWF-India have created new identification (ID) tools in the form of pocket-sized Identification Cards and a foldable Poster on all 28 species of tortoises and freshwater turtles found in India to help enforcement officers identify the species encountered in illegal wildlife trade.

Introduction: Vertebral fractures are very commonly encountered in day to day practice. Diffusion Weighted Imaging (DWI) with Apparent Diffusion Coefficent (ADC) values is a novel technique to evaluate vertebral fractures. Aim: To establish the role of DWI in differentiating benign from pathologic vertebral fractures using ADC values in comparison...

Red Junglefowls (RJFs), the wild progenitor of modern day chickens (DCs), are believed to be in genetic endangerment due to introgression of domestic genes through opportunistic matings with domestic or feral chickens. Previous studies from India reported rare hybridiza-tion of RJFs in the wild. However, RJF population genetic structure, pattern of...

Median joining haplotype network of 38 wild RJFs that represented 31 haplotypes. (Haplotypes of four RJF populations are represented in different colored circles. The size of the circle is proportional to the haplotype frequency. Haplotype 3 is shared between North and Northeast populations). (TIF)

The number of cluster (K) simulated from the posterior distribution of the best run showing the highest average logarithm of the posterior probability in GENELAND analysis. Analysis was conducted under the spatial model with uncorrelated allele frequencyincorporating latitude/longitude. (TIF)

Objective: Ultrasonography is an efficient technique for detecting fatty liver. Its sensitivity and specificity in detecting moderate to severe fatty liver are comparable to those of histology. Fatty liver is associated with abnormal lipid and lipoprotein metabolism and insulin resistance, metabolic syndrome, cardiovascular/renal disease, type 2 d...

A single-crystal-to-single-crystal solid-state reaction involving the 2 : 1 charge-transfer complex of 9-bromoanthracene and bis(N-cyclobutylimino)-1,4-dithiin leads to a synthetic co-crystal composed of the Diels-Alder cycloadduct and unreacted 9-bromoanthracene molecules. Analysis of close contacts in the product crystal and DFT energy calculatio...

This paper reports the results of a study conducted along the Sindhudurg coast using square and diamond mesh codends of 30 mm size and 1.25 mm thickness. A total of 38 hauls using diamond mesh and 44 using square mesh codends were used for the analysis. The mean CPUE – Catch Per Unit Effort, (kg.h.-1) for diamond mesh (18.77) and square mesh codend...

Aims and objectives: Cerebral ischemic stroke is life-threatening and debilitating neurological disease, it is the third leading cause of death in the world. Studies have shown that there is a close relationship between carotid artery stenosis and ischemic cerebral vascular disease. This study is done to assess the carotid arteries with the help o...

Electron donor/acceptor (EDA) interactions have been found to be very useful in engineering reactive heteromolecular crystals, but few examples have been reported in the literature. By utilising EDA interactions, crystals of charge-transfer (CT) complexes were formed with bis(N-allylimino)-1,4-dithiin as the electron acceptor and 9-bromoanthracene...

Alzheimer's disease (AD) is an irreversible and progressive brain disease that gradually destroys memory and thinking skills to an extent that it starts affecting the daily life. It has become the most common cause of dementia among older people. The work presented in this paper evaluates the utility of image processing on the Magnetic Resonance Im...

Background: Objective of current study was to determine and compare the diagnostic performance of Doppler ultrasonography of the fetal Middle Cerebral Artery (MCA) and Umbilical Artery (UA) for prediction of adverse perinatal outcome in suspected intrauterine growth restriction (IUGR). Methods: Fifty singleton pregnancies in third trimester of preg...

The silent sinus syndrome, also known as imploding antrum and chronic maxillary sinus atelectasis, consists of painless enophthalmos, facial asymmetry with inward retraction of the ipsilateral maxillary sinus walls as seen on imaging studies. It is a well-recognized entity in the field of otolaryngology, but the syndrome remains relatively unknown...

Genetics driven interventions (GDI) are imperative for ex situ conservation to exhort long-term sustenance of small and isolated populations in captivity as they are more prone to an increased extinction risk due to inbreeding and genetic drift. We investigated constitutive genetic attributes of four captive Red Junglefowl (RJF) populations in Indi...

The Red Junglefowl (RJF) is believed to be the wild ancestor of all domestic chicken in the world. there still exist a strong ethno-cultural bond where the wild males are used to invigorate the domestic stock in order to enhance the first generation individuals that are used in the context of cultural and religious relevance. Concerns were raised o...

In studies dealing with genetic and disease prognosis, biological sampling is a prerequisite. Earlier, blood and muscle samples were taken after live captures. These invasive procedures are of considerable risk when sampling endangered species. Therefore, non invasive samples like shed feathers/hairs, faeces and hatched or predated egg shells are t...

The red junglefowl (RJF) is one of the most important species for mankind, due to economic and cultural reasons. Recently, fears have been expressed that the wild RJF may be genetically contaminated, leading to an inference that there may not be any pure RJF left in the wild. In order to assess the distribution of RJF in India, field surveys were c...

Chromatin structure can modulate gene expression by limiting transcription factor access to gene promoters. We examined sequence elements of the Drosophila hsp70 promoter for their ability to facilitate the binding of the transcription factor, heat shock factor (HSF), to chromatin. We assayed HSF binding to various transgenic heat shock promoters i...
