Abstract Health care services are being confronted by a daily dilemma of who can receive critical care and who cannot. In a palliative care clinic, this apprehension gets exemplified, as these patients have limited life expectancy. The head and neck region further makes things critical, as it comprises of all the sites through which the SARS‐CoV‐2 can be transmitted. This document strives to define the ways in which the head and neck cancer services can contribute to better patient care in a triage...

Abstract Health crises have become a popular topic of discussion. In the wave of the ongoing pandemic, experts have suggested the role of vaping and other tobacco product use exemplifying the vulnerability of the population to contract the COVID‐19. We discuss some of the events that led up to these conclusions and also offer a unique insight into another form of tobacco use that is potentially propagating its spread especially in the South Asian region—chewed tobacco. Both of these have been a...

The deposition of beta-amyloid (Aβ) in the brain is detected in Alzheimer’s disease and during ageing. Until now, ultrastructural studies of changes caused by Aβ in the dentate gyrus are very scarce. The effects of Aβ 1-42 injection into the CA1 field of rat hippocampus were studied by electron microscopy. In 2 weeks after injection of aggregated Aβ in low concentrations, destructive changes were seen in the structure of dentate gyrus cells, which consisted in a decrease in the number of dentate...

Abstract The interaction between CD47 and signal‐regulatory protein alpha (SIRPα) inhibits phagocytosis, thus affecting the clinical outcomes of neoplastic diseases. Although CD47 upregulation is associated with poor prognosis in several malignancies, the effect of SIRPα expression and its co‐expression with CD47 remains unclear. This study aimed to investigate the clinicopathological effect of CD47 and SIRPα expression in diffuse large B‐cell lymphoma (DLBCL). Immunostaining of 120 biopsy samples...

Abstract Chemoresistance is a main obstacle in ovarian cancer therapy and new treatment strategies and further information regarding the mechanism of cisplatin are urgently needed. Nitric oxide has a critical role in modulating the activity of chemotherapeutic drugs and our previous work shows that Connexin32 contributes to cisplatin resistance. However, whether Nitric oxide is involved in Connexin32‐mediated cisplatin resistance remains unknown. In this study, with A2780 and A2780 cisplatin‐resistant...

Abstract Cancer stem cells (CSCs) play a decisive role in the development and progression of cancer. To investigate CSCs in Epstein‐Barr virus (EBV)‐associated carcinoma (EBVaGC), we screened previously reported stem cell markers of gastric cancer in EBV‐infected gastric cancer cell lines (TMK1, NUGC3) and identified CD44v6v9 double positive cells as candidate CSCs. CD44v6/v9+/+ cells were sorted from EBVaGC cell line (SNU719) cells and EBV‐infected TMK1 cells and these cell populations showed...

Abstract Previous studies on the association of adiposity with endometrial cancer risk have mostly used body mass index (BMI) as the main exposure of interest. Whether more precise measures of body fat, such as body fat percentage and fat mass estimated by bioimpedance analyses, are better indicators of risk than BMI is unknown. The role of central adiposity and fat‐free mass in endometrial cancer development remains unclear. We used Cox regression models to estimate hazard ratios (HR) and corresponding...
