The results of stress analysis of a ceramic matrix composite (CMC) vane using a physics-based model developed for two-dimensional woven CMCs are presented. The model considers the inherent defects and micromechanical damage in woven CMCs along with time-dependent deformation of the constituents. Predictions include damage state under general load conditions and the global deformation response of the vane. Strain-gage data from burst tests are compared to strain predictions obtained using the model. Results from tim [...]

Recently, numerous studies have reported convincing data suggesting that chromosome instability may be not only a trigger of cancers but a possible mechanism for a wide spectrum of brain diseases. According to our original experience, chromosome instability is commonly observed during karyotyping of children with neuropsychiatric diseases and congenital malformations. To understand mechanisms of non-cancerous diseases potentially mediated by chromosome instability, which may represent an important target for molecu [...]

This paper explores views of healthcare professionals (HCPs) in genetics and foetal medicine settings on offering pre-natal diagnosis (PND) for adult onset cancer susceptibility (AOCS) genes. Study participants came from different disciplinary backgrounds and all had considered implications of offering PND for AOCS, directly or indirectly, from professional and personal perspectives. Foetal medicine and genetics teams are accustomed to offering PND with the possibility of terminating an affected foetus on the basis [...]

Glioblastoma (GBM) is malignant, primary intracranial neoplasm associated with poor outcomes. Maximal, safe cytoreduction remains an important component of effective treatment for patients with this disease; however, some patients are not candidates for resection due to comorbid status, tumor location, or other factors. In this review, we aimed to describe minimally invasive surgical techniques that are emerging as important tools for improving safety and efficiency in GBM cytoreduction, including for patients with [...]

Chromosome abnormalities are a leading cause of pregnancy loss, developmental delays, and birth defects. These abnormalities arise from errors in chromosome structure (breakage) or number (missegregation) during cell division. Understanding the causes of these errors is crucial for developing effective preventive strategies to improve reproductive health. This paper aims to review the known causes of chromosome breakage and mis-segregation, emphasizing their impact on pregnancy and newborn health. It further explor [...]

Background: The objective of this study was to evaluate the effects of acute moderate-intensity exercise on autobiographical episodic memory and semantic memory. Methods: A two-arm, parallel-group randomized controlled intervention was employed. The experimental group engaged in an acute bout of treadmill exercise for 15 minutes (70% of heart rate max), while the control group engaged in a time-matched seated activity. For episodic autobiographical memory, participants recalled as many personal memories of events f [...]

The novel coronavirus COVID-19 is a viral pathogen that first emerged in Wuhan, China in 2002 and has spread to 202 countries (as of March 28, 2020) [1]. Despite the fact that the 2005 SARS-CoV pandemic infected over 8,500 people, and caused over 800 deaths with billions of dollars in economic loss worldwide, as of 2015 there were still no clinically approved antiviral drugs, vaccines or monoclonal antibody therapies to treat SARS-CoV infections [2]. Antiviral medications that have been used to treat or control oth [...]

The present need for an energy transition in the wake of a global climate catastrophe led to the “EU green deal” which requires a transition of the energy system in all countries. This study aimis survey aims to identify strategies within such an energy transition based on global trend analyses and reports on available technologies for implementation. Based on a literature analysis of over 300 pieces (of feasibility studies and technology implementation reports with a focus on Central Europe) and a statistical anal [...]

Catatonia and malignant catatonia may result in devastating and life-threatening complications like pulmonary embolisms, pneumonia, deep venous thrombosis, rhabdomyolysis, and even death. There have been documented cases implicating alcohol withdrawal as a significant culprit in catatonia. Here, we provide a unique case report of a patient with a complicated medical course, who subsequently developed malignant catatonia secondary to severe alcohol withdrawal, and was successfully treated using both first line treat [...]
