Sex cord ovarian tumours over 10 years: a retrospective analysis of clinicopathological profile and outcome.

Objectives: To retrospectively describe the clinicopathological profile and treatment outcome of sex cord ovarian tumours (SCOTs), from a single institution.

Methods: Patients who operated for SCOT between January 2011 and December 2020 were identified from the institution's discharge summaries. Treatment details and oncologic outcomes were analyzed using descriptive statistics, SPSS statistics version 21.

Analysis of the effect of baseline detection and early clearance of ct-DNA, on survival outcomes among patients with advanced EGFR-mutant non-small cell lung cancer.

Background: To determine if circulating tumor DNA (ct-DNA) dynamics of epidermal growth factor receptor (EGFR) mutation in plasma can identify a subset of patients with EGFR-mutant (EGFR- m) non-small cell lung cancer (NSCLC) with inferior survival outcomes, we analyzed and compared survival outcomes among patients with and without baseline presence and early clearance of EGFR ct-DNA in plasma.

Material And Methods: For 66 patients newly dia-gnosed with EGFR- m NSCLC, plasma samples were collected at baseline and 1st response assessment at 12-24 weeks for extraction of ct-DNA. Estimation of ct-DNA (EGFR exons 18, 19, 20 and 21) was done using droplet digital polymerase chain reaction (dd-PCR) on the QX200 ddPCR system (BioRad, USA).

Anti-phosphohistone H3 (PHH3) as a proliferation marker to assess mitotic activity and to grade neuroendocrine neoplasms of hepatopancreaticobiliary (HPB) system.

Background: The world health organization (WHO) classification of neuroendocrine neoplasms (NENs, i.e. neuroendocrine tumors (NETs) and neuroendocrine carcinomas (NECs)) of the gastrointestinal system involves grading of these tumors by mitotic count (i.

Hierarchical looping results in extreme extensibility of silk fibre composites produced by Southern house spiders ().

Spider silk is a tough and versatile biological material combining high tensile strength and extensibility through nanocomposite structure and its nonlinear elastic behaviour. Notably, spiders rarely use single silk fibres in isolation, but instead process them into more complex composites, such as silk fibre bundles, sheets and anchorages, involving a combination of spinneret, leg and body movements. While the material properties of single silk fibres have been extensively studied, the mechanical properties of silk composites and meta-structures are poorly understood and exhibit a hereto largely untapped potential for the bio-inspired design of novel fabrics with outstanding mechanical properties.

Randomized Placebo-Controlled Trial of Topical Capsaicin for Delayed Chemotherapy-Induced Nausea and Vomiting.

Purpose: We examined the efficacy of topical capsaicin in reducing delayed chemotherapy-induced nausea and vomiting (CINV).

Methods: Adults on highly emetogenic chemotherapy regimens applied 2 g of capsaicin ointment (0.075%) or matching placebo four times a day to the abdomen for 5 days in addition to standard antiemetic regimen in this blinded randomized controlled trial.
