Estimating realized relatedness in free-ranging macaques by inferring identity-by-descent segments.

Proc Natl Acad Sci U S A

January 2025

Department of Primate Behavioral Ecology, Institute of Biology, Leipzig University, Leipzig 04103, Germany.

Biological relatedness is a key consideration in studies of behavior, population structure, and trait evolution. Except for parent-offspring dyads, pedigrees capture relatedness imperfectly. The number and length of identical-by-descent DNA segments (IBD) yield the most precise relatedness estimates.

[Importance of genetics in pediatric nephrology].

Andes Pediatr

August 2023

Fundación Valle del Lili, Cali, Colombia.

Advances in the field of genetics and genomics have had a great impact on the clinical practice of the pediatric nephrologist. Access to diagnostic genetic studies for renal pathologies allows not only to confirm specific diagnoses, but also to provide management and follow-up strategies, knowledge about prognosis, and prevention of complications. In addition, it provides genetic counseling to the patient and family and even helps to make decisions about family donor transplantation.

Comparative Study of Iminodibenzyl and Diphenylamine Derivatives as Hole Transport Materials in Inverted Perovskite Solar Cells.

Chemistry

January 2025

Friedrich-Alexander-Universität Erlangen-Nürnberg: Friedrich-Alexander-Universitat Erlangen-Nurnberg, Department of Materials Science and Engineering, Institute of Materials for Electronics and Energy Technology (i-MEET), Martensstraße 7, 91058, Erlangen, GERMANY.

Perovskite solar cells (PSCs) have recently achieved over 26% power conversion efficiency, challenging the dominance of silicon-based alternatives. This progress is significantly driven by innovations in hole transport materials (HTMs), which notably influence the efficiency and stability of PSCs. However, conventional organic HTMs like PTAA, although highly efficient, suffer from thermal degradation, moisture ingress, and high cost.

A green methodology for the synthesis of carbon quantum dots (CQDs) from coffee husk without the use of any toxic solvents is proposed in this work. Sonochemical exfoliation of biochar, obtained from the thermal carbonization of coffee husk (from a certified coffee seeds) at low temperature in an air-restricted atmosphere, is described as an alternative procedure for the sustainable production of CQDs. The synthesized CQDs exhibited blue fluorescence with a strong maximum emission band at 410 nm when excited at a maximum absorption wavelength of 330 nm.

Background: Low-value care refers to the provision of health services that confer little or no benefit to patients, or have the potential to incur unwarranted harms. A breadth of literature exists investigating geographical variations in rates of potential low-value interventions for musculoskeletal pain. This scoping review aimed to examine the provision of low-value care for osteoarthritis and lower back pain by degree of rurality (e.

Recent research suggests that performance on Statistical Learning (SL) tasks may be lower in children with dyslexia in deep orthographies such as English. However, it is debated whether the observed difficulties may vary depending on the modality and stimulus of the task, opening a broad discussion about whether SL is a domain-general or domain-specific construct. Besides, little is known about SL in children with dyslexia who learn transparent orthographies, where the transparency of grapheme-phoneme correspondences might reduce the reliance on implicit learning processes.

Biological control, which utilizes nematophagous fungi to reduce gastrointestinal nematode populations, may effectively diminish the need for chemical anthelmintic treatments. However, the limited knowledge surrounding the mass production of chlamydospores hinders the widespread use of biological products as alternatives to traditional anthelmintics. This study aimed to evaluate the development of liquid culture media for the large-scale production of the nematophagous fungi Duddingtonia flagrans using a systematic procedure, progressing from microplates to bioreactor.

Floodplain forests drive fruit-eating fish diversity at the Amazon Basin-scale.

Proc Natl Acad Sci U S A

January 2025

Centre de Recherche sur la Biodiversité et l'Environnement, Université de Toulouse, Institut de Recherche pour le Développement, Institut National Polytechnique de Toulouse, Université Toulouse 3 - Paul Sabatier, Toulouse F-31062, France.

Unlike most rivers globally, nearly all lowland Amazonian rivers have unregulated flow, supporting seasonally flooded floodplain forests. Floodplain forests harbor a unique tree species assemblage adapted to flooding and specialized fauna, including fruit-eating fish that migrate seasonally into floodplains, favoring expansive floodplain areas. Frugivorous fish are forest-dependent fauna critical to forest regeneration via seed dispersal and support commercial and artisanal fisheries.

PLoS One

January 2025

Department of Fish and Wildlife Conservation, Virginia Tech, Blacksburg, VA, United States of America.

Rabies is a zoonotic infectious disease of global distribution that impacts human and animal health. In rural Latin America, rabies negatively impacts food security and the economy due to losses in livestock production. The common vampire bat, Desmodus rotundus, is the main reservoir and transmitter of rabies virus (RABV) to domestic animals in Latin America.

This paper develops the methodological concept of river co-learning arenas (RCAs) and explores their potential to strengthen innovative grassroots river initiatives, enliven river commons, regenerate river ecologies, and foster greater socio-ecological justice. The integrity of river systems has been threatened in profound ways over the last century. Pollution, damming, canalisation, and water grabbing are some examples of pressures threatening the entwined lifeworlds of human and non-human communities that depend on riverine systems.

Femtosecond laser-assisted cataract surgery (FLACS) is a useful technology for anterior segment surgery that creates cleavage planes via photodisruption of ocular tissue. Compared to conventional cataract surgery, FLACS has been thought to potentially improve surgical precision, accuracy, and reproducibility. Its introduction into cataract surgery has enabled the development of new techniques and has been purported to be potentially beneficial in improving surgical safety and providing quicker visual rehabilitation.
