Comparing four different methods of measuring fracture toughness and its relationship with fractal dimension in a polycrystalline (3Y-TZP) dental ceramic.

Objectives: Previous studies reported various methods of measuring fracture toughness of dental ceramics. The objectives of this study were to compare different methods and to validate fractal analysis to estimate fracture toughness for a polycrystalline dental ceramic.

Methods: Bar-shaped specimens were prepared from 3 mol% yttria-stabilized tetragonal polycrystalline (3Y-TZP) ceramic.

Extract Improves Vascular Dysfunction in Obese Mice Fed a High-Fat Diet.

Background: Obesity is a risk factor for developing cardiovascular diseases (CVDs) by impairing normal vascular function. Natural products are gaining momentum in the clinical setting due to their high efficacy and low toxicity. extract (CFE) has been shown to control appetite and promote weight loss; however, its effect on vascular function remains poorly understood.

The Impact of Parental Preconception Nutrition, Body Weight, and Exercise Habits on Offspring Health Outcomes: A Narrative Review.

An increasing number of studies highlight the critical role of both maternal and paternal nutrition and body weight before conception in shaping offspring health. Traditionally, research has focused on maternal factors, particularly in utero exposures, as key determinants of chronic disease development. However, emerging evidence underscores the significant influence of paternal preconception health on offspring metabolic outcomes.

Helicopter emergency medical services demonstrate reduced time to emergency anaesthesia in an undifferentiated trauma population: a retrospective observational analysis across three major trauma networks.

Background: Early rapid sequence induction of anaesthesia (RSI) and tracheal intubation for patients with airway or ventilatory compromise following major trauma is recommended, with guidance suggesting a 45-min timeframe. Whilst on-scene RSI is recommended, the potential time benefit offered by Helicopter Emergency Medical Services (HEMS) has not been studied. We compared the time from 999/112 emergency call to delivery of RSI between patients intubated either in the Emergency Department or pre-hospital by HEMS.
