Differential effects of gestational Cannabis smoke and phytocannabinoid injections on male and female rat offspring behavior.

Our understanding of the implications of gestational Cannabis exposure (GCE) remains unclear as Cannabis use increases worldwide. Much of the existing knowledge of the effects of GCE has been gained from preclinical experiments using injections of isolated Δ-tetrahydrocannabinol (THC) at relatively high doses. Few investigations of the effects of GCE to smoke from the whole Cannabis flower have been conducted, despite this being the most common mode of human consumption.

Variation in whale (Cetacea) inner ear anatomy reveals the early evolution of "specialized" high-frequency hearing sensitivity.

As fully aquatic mammals, hearing is arguably the most important sensory component of cetaceans. Increasingly, researchers have been harnessing computed tomography (CT) to investigate the details of the inner ear as they can provide clues to the hearing abilities of whales. We use microCT scans of a broad sampling of the ear bones (periotics) of primarily toothed whales (Odontoceti) to investigate the inner ear bony labyrinth shape and reconstruct hearing sensitivities among these cetaceans, including several taxa about which little is currently known.

Biomechanical Analysis of Diffuse Idiopathic Skeletal Hyperostosis and Osteoporosis: Vertebral Fracture Risk Evaluation Using Finite Element Modeling with Clinical and Micro-CT Data in an Elderly Donor.

Biomechanical analysis of spinal structures is crucial in the evaluation of injuries, the risk of fracture, and age-related changes. Osteoporotic vertebrae are very fragile and therefore constitute a serious risk, especially in the elderly. At present, clinically relevant decision making in fracture risk assessment is predicated upon finite element analysis (FEA), which utilizes high-resolution computed tomography (CT) scans from clinical practice alongside micro-CT scans from laboratory settings.

Influenza in Adults Seeking Care at Seven European Emergency Departments: A Prospective Active Surveillance During the 2019-2020 Influenza Season.

Background: Influenza can be associated with nonrespiratory disease presentation, but these are less well documented due to the lack of routine testing for influenza in the healthcare system, especially if patients do not present with influenza-like illness (ILI). We aimed to measure the proportion of influenza cases seeking care at emergency department (ED) for a nontraumatic cause, to describe their clinical presentation and their ED-discharge diagnosis.

Methods: The study was conducted at seven hospitals in France, Spain, Italy and Germany during the 2019-20 influenza season, for a period of 10 weeks.
