Owls are often associated with superstitions and witchcraft in various cultures, leading to conflicts between human communities and these birds. This study, conducted in 2023 across 16 villages in Andapa, a northern district of Madagascar, aimed to investigate the challenges of human-owl coexistence. It specifically explored the cultural beliefs and conflicts driving the motivation to kill owls, particularly during witch-hunting incidents between 2021 and 2022. The findings revealed a prevalent belief among the local population in the close association between witches and owls. Both villagers and witches demonstrated a lack of understanding of environmental laws and regulations, intensifying motivations for owl hunting. The limited awareness of the legal consequences of hunting owls among the local population, combined with a lack of understanding among witches about the law prohibiting the keeping of owls as domestic companions, significantly contributes to this issue. Furthermore, the analysis showed that individuals with strong traditional beliefs or who had encountered dead owls were more likely to engage in owl hunting. Conversely, those more educated, knowledgeable about wildlife protection laws, or aware of the ecological importance of owls were less likely to participate in such practices. This study underscores the urgent need to raise awareness of owls' ecological value, improve understanding of wildlife protection laws, and promote education to reduce owl-hunting behavior in the region.

Herein, a novel and simple electrospray (ES) printing technique was developed for the fabrication of ultrathin graphene layers with precisely controlled nanometer-scale thickness, where graphene oxide (GO) was electrosprayed on wafers and subsequently chemically reduced into reduced GO (rGO). Utilizing that technique, we prepared ultrathin rGO in-plane graphene field-effect transistor (GFET)-based biosensors coupled with a portable prototype measuring system for point-of-care detection of pathogens. We illustrate the use of such prepared GFETs to detect COVID-19, using the SARS-CoV-2 nucleocapsid protein antigen (N-protein) and genomic viral RNA as detection targets.

Background: Infection is a leading cause of death after pediatric heart transplants (PHTs). Understanding of common pathogens is needed to guide testing strategies and empiric antibiotic use.
Methods: We conducted a 3-center retrospective study of PHT recipients ≤18 years old presenting to cardiology clinics or emergency departments (EDs) from 2010 to 2018 for evaluation of suspected infections within 2 years of transplant.

One of the major advancements in fertilization (IVF) has been the development of culture media that enhance gamete maturation and sustain embryo development up to the blastocyst stage. The deep understanding of the mechanisms involved in gametogenesis and the complex sequence of events surrounding nuclear and cytoplasmic maturation has also enabled the development of efficient maturation (IVM) protocols. This review outlines the major landmarks in the history of maturation of oocytes, the advantages and importance of its clinical application in human, especially in patients with Polycystic Ovary Syndrome (PCOS), Resistant Ovary Syndrome, high antral follicle count or oncology patients, as well as the safety and efficacy of the technique.

Congenital cytomegalovirus (cCMV) is the leading infectious cause of neonatal neurological impairment worldwide, but the viral factors enabling vertical spread across the placenta remain undetermined. The pentameric complex (PC), composed of the subunits gH/gL/UL128/UL130/UL131A, has been demonstrated to be important for entry into nonfibroblast cells in vitro. These findings link the PC to broad cell tropism and virus dissemination in vivo, denoting all subunits as potential targets for intervention strategies and vaccine development.

Aortic valve stenosis (AVS) is a progressive disease, wherein males more often develop valve calcification relative to females that develop valve fibrosis. Valvular interstitial cells (VICs) aberrantly activate to myofibroblasts during AVS, driving the fibrotic valve phenotype in females. Myofibroblasts further differentiate into osteoblast-like cells and produce calcium nanoparticles, driving valve calcification in males.
