The Caucasian viper Macrovipera lebetina obtusa (MLO) is one of the most prevalent and venomous snakes in the Caucasus and the surrounding regions, yet the effects of MLO venom on cardiac function remain largely unknown. We examined the influence of MLO venom (crude and with inhibited metalloproteinases and phospholipase A) on attachment and metabolic activity of rat neonatal cardiomyocytes (CM) and nonmyocytes (nCM), assessed at 1 and 24 h. After exposing both CM and nCM to varying concentrations of MLO venom, we observed immediate cytotoxic effects at a concentration of 100 μg/ml, causing detachment from the culture substrate.

For the first time in history, the United States surpassed 100 000 overdose-related deaths in a 12-month period, driven by synthetic opioids such as fentanyl. Also, for the first time, potential chemical weapons are readily available on the streets and the dark web. Opioids represent a rare trifecta, used for licit pain management, as an illicit drug of abuse, and with potential use as a weapon of terror.

Introduction: The current war in Ukraine and the subsequent deployment of Non-Governmental Organizations (NGOs) from around the world has highlighted the many potential dangers faced by humanitarian aid workers operating in conflict zones. Humanitarian aid workers may face both direct and indirect threats and aggression while on deployment, and given the rising number of global conflicts, the authors postulate a need to incorporate threat awareness training as part of pre-deployment training.

Methods: A list of the top 22 rated NGOs providing international aid was obtained from CharityWatch.

Increasing concern about the use of animal models has stimulated the development of in vitro cell culture models for analysis of the biological effects of snake venoms. However, the complexity of animal venoms and the extreme synergy of the venom components during envenomation calls for critical review and analysis. The epithelium is a primary target for injected viper venom's toxic substances, and therefore, is a focus in modern toxinology.

Article Synopsis
  • The study investigates the current emergency medical services (EMS) system in Armenia, which faces challenges due to limited training and experience in disaster medicine, particularly with a recent history of concurrent crises: the 2020 Nagorno-Karabakh War and the COVID-19 pandemic.
  • A cross-sectional survey conducted among Yerevan EMS physicians showed a 70.6% response rate, revealing that many providers had minimal experience in treating war-related injuries or mass casualties, with most being relatively new to their roles and still in residency.
  • Results indicate that greater experience in battlefield medicine correlates with older age and longer service as a physician or EMS provider, highlighting the need for improved training and preparedness in Armenia

A recently discovered new family of 3D halide perovskites with the general formula (A)()(Pb)(X) (A = MA, FA; X = Br, I; MA = methylammonium, FA = formamidinium, = ethylenediammonium) is referred to as "hollow" perovskites owing to extensive Pb and X vacancies created on incorporation of cations in the 3D network. The "hollow" motif allows fine tuning of optical, electronic, and transport properties and bestowing good environmental stability proportional to loading. To shed light on the origin of the apparent stability of these materials, we performed detailed thermochemical studies, using room temperature solution calorimetry combined with density functional theory simulations on three different families of "hollow" perovskites namely /FAPbI, /MAPbI, and /FAPbBr.

The metalloproteinases and phospholipase A are the main enzymes in the venom of that play a decisive role in the destructive and toxic effects on the organism of the prey. Metalloproteinases cause hemorrhagic damage, destroy the basement membrane of the blood vessel and disrupt the connections between endothelial cells. Phospholipase A2 causes hemolysis of erythrocytes, destroy the cell membranes, and inhibits the adhesion of platelets and so on.

Introduction: The absence of local Emergency Medical Services (EMS) educational programs in Bahrain has given rise to an EMS workforce comprised predominantly of expatriate personnel with varying educational backgrounds that require further training before being licensed as EMS providers in Bahrain.

Methods: A qualitative variance analysis was performed comparing desired core competencies for EMS practice in neighbouring Saudi Arabia, used as a comparator for Bahrain, with core competencies extracted from national curricula of the major countries from which expatriate providers originate.

Results: Major core competencies not covered by the expatriate providers' curricula were identified as follows: working in an autonomous environment, requiring different critical thinking and decision-making skills, assessment and treatment during transportation, disaster response, EMS knowledge base, and coping with the different stressors of the prehospital environment.
