Lymphadenopathy can be due to multitude of causes. Owing to the high prevalence of infectious diseases in India, and malignancy being a life threatening cause for lymphadenopathy; accurate diagnosis is important in preventing delay or misdiagnosis and in improving patient care, thereby increasing longevity with quality. Fine needle aspiration cytology (FNAC) is the first line investigation commonly done. Should the doctor be contented with the benign FNAC or is a lymph node biopsy needed in this age? The aims of this study are the following: (1) to study the spectral pattern of lymph node biopsies done in a surgical oncology unit of tertiary care centre, (2) to assess the yield of malignant cases from lymph node biopsy and (3) to compare the reliability of benign FNAC with lymph node biopsy...

Adhesion molecules hold cells together but also couple cell membranes to a contractile actomyosin network, which limits the expansion of cell contacts. Despite their fundamental role in tissue morphogenesis and tissue homeostasis, how adhesion molecules control cell shapes and cell patterns in tissues remains unclear. Here we address this question in vivo using the Drosophila eye. We show that cone cell shapes depend little on adhesion bonds and mostly on contractile forces. However, N-cadherin has an indirect control on cell shape...

BACKGROUND: Prostate cancer is biologically and clinically a heterogeneous disease that makes imaging evaluation challenging. One of the important challenges in this cancer is to detect recurrent disease. Biochemical response using Prostate Specific Antigen (PSA) and Imaging using several PET tracers have poor sensitivity and specificity. Therefore, we analyse the role of Ga68-PSMA (Prostate Specific Membrane Antigen) imaging in prostate cancer, which is a new PET tracer. METHODS: In this study, we evaluated PET scans of 262 patients with diagnosis of prostate cancer...

BACKGROUND: Long-standing ulcerative colitis (UC) leading to colorectal cancer (CRC) is one of the most serious and life-threatening consequences acknowledged globally. Ulcerative colitis-associated colorectal carcinogenesis showed distinct molecular alterations when compared with sporadic colorectal carcinoma. METHODS: Targeted sequencing of 409 genes in tissue samples of 18 long-standing UC subjects at high risk of colorectal carcinoma (UCHR) was performed to identify somatic driver mutations, which may be involved in the molecular changes during the transformation of non-dysplastic mucosa to high-grade dysplasia...

Dopamine D2 and D3 receptors are important pharmacological targets in Schizophrenia and Parkinson's disease. Intriguingly, many studies have shown that they form homo- and heterodimers, and they can be targeted in specific tissues with new drugs. In this direction, many efforts have been made to develop new molecules that are able to interact with these receptor dimeric complexes. Among various strategies for targeting dopamine receptors dimers, two distinct classes of compounds, such as bivalent and bitopic ligands, have gained particular attention and their use in pharmacology looks promising...

BACKGROUND: Allogeneic hematopoietic stem-cell transplantation (ahsct) is associated with significant morbidity and mortality, but it can cure carefully selected patients with acute myeloid leukemia (aml) in second remission (cr2). In a cohort of patients with aml who underwent ahsct in cr2, we determined the pre-transplant factors that predicted for overall survival (os), relapse, and non-relapse mortality. We also sought to validate the prognostic risk groups derived by Michelis and colleagues in this independent population...

In the United States, long standing deep infections of joint arthroplasty, such as total knee and total hip replacements, are treated with two-stage exchange. This requires the removal of the prior implant, placement of an antibiotic eluting spacer block made of polymethylmethacrylate (PMMA), followed by re-implantation of a new implant after treatment with intravenous antibiotics for six to eight weeks. Unfortunately, the use of PMMA as a spacer material has limitations in terms of mechanical and drug-eluting properties...

A core-fucose-specific lectin, CSL from Cephalosporium curvulum, has been reported earlier. Here we assign the role for CSL and another lectin AOL, from pathogenic fungus Aspergillus oryzae, in causing mycotic keratitis. CSL and AOL show strong binding to immortalized and primary human corneal epithelial cells (HCECs) which are inhibited by asialofetuin, confirming their glycan-mediated binding. CSL and AOL showed increase in viability at lower concentrations (0.07 µg/ml) whereas at higher concentrations (0...

Isolated mediastinal adenopathy is a diagnostic challenge in the paediatric population, often requiring invasive surgical procedures for diagnosis. We describe a novel minimally invasive modality in a 20 month toddler-transesophageal bronchoscopic ultrasound-guided fine-needle aspiration (EUS-B-FNA). This is the youngest reported use of this modality, highlighting feasibility, technical issues, safety, and rapid diagnosis leading to expedited treatment.

While volume deficit of hippocampus is an established finding in schizophrenia, very few studies have examined large sample of patients without the confounding effect of antipsychotic treatment. Concurrent evaluation of hippocampus shape will offer additional information on the hippocampal aberrations in schizophrenia. In this study, we analyzed the volume and shape of hippocampus in antipsychotic-naïve schizophrenia patients (N=71) in comparison to healthy controls (N=82). Using 3-T MRI data, gray matter (GM) volume (anterior and posterior sub-divisions) and shape of the hippocampus were analyzed...

Rising cancer incidence and mortality in India emphasize the need to address the increasing burden of this disease and the stark inequities in access to radiotherapy and other essential medical treatments. State-of-the-art technology is available within the private sector and a few hospitals in the public sector, but 75% of patients in the public sector in India do not have access to timely radiotherapy. This inequity in access to radiotherapy in the public sector is amplified in rural areas, where most of India׳s population lives...
