Pasture access and social housing influence the behaviour of dairy calves.

This Research Communication set out to (1) evaluate the behaviour and performance of dairy calves raised on pasture individually or in groups, and (2) evaluate the influence of physical enrichment on the behaviour and performance of dairy calves raised in groups on pasture. Although there was no difference in grazing behaviour when housed in groups, calves spent longer eating concentrate, ruminating and drinking water. Additionaly, calves housed individually spend part of their time trying to get close to a neighbouring calf.

Innovative Photoprotection Strategy: Development of 2-(Benzoxazol-2-Yl)[(2-Hydroxynaphthyl)Diazenyl] Phenol Derivatives for Comprehensive Absorption of UVB, UVA, and Blue Light.

Overexposure to blue light due to the excessive use of electronic devices has been implicated in premature skin aging and eye damage, among other injuries to health. This study aimed to synthesize two azo derivatives of the 2-(amino-2'-hydroxyphenyl) benzoxazole and explore their potential as UV and blue light filters, proposing a new spectral profile. The synthesis of the heterocyclic compounds involved condensation reactions and diazotation.

A meta-analysis approach to evaluate the effects of early group housing on calf performance, health, and behavior during the preweaning period.

This study aimed to evaluate the effects of early group housing on the performance, health, and behavior of dairy calves during the preweaning period using systematic and meta-analysis approaches. Peer-reviewed articles written in English that compared dairy calves individually and group-housed with performance, health, or behavior outcomes were collected from Web of Science, PubMed, and CABDirect databases. The resulting articles (n = 850) underwent a 4-step appraisal process following the Preferred Reporting Items for Systematic Review and Meta-Analyses protocols, resulting in a final sample of 51 articles containing 85 studies.

In Vivo Effects of Biosilica and Spongin-Like Collagen Scaffolds on the Healing Process in Osteoporotic Rats.

Due to bioactive properties, introducing spongin-like collagen (SPG) into the biosilica (BS) extracted from marine sponges would present an enhanced biological material for improving osteoporotic fracture healing by increasing bone formation rate. Our aim was to characterize the morphology of the BS/SPG scaffolds by scanning electron microscopy (SEM), the chemical bonds of the material by Fourier transform infrared spectroscopy (FTIR), and evaluating the orthotopic in vivo response of BS/SPG scaffolds in tibial defects of osteoporotic fractures in rats (histology, histomorphometry, and immunohistochemistry) in two experimental periods (15 and 30 days). SEM showed that scaffolds were porous, showing the spicules of BS and fibrous aspect of SPG.

Comparing Self-Fitting Strategies for Over-the-Counter Hearing Aids: A Crossover Clinical Trial.

Importance: Fewer than 20% of US adults with hearing loss use hearing aids due to barriers like high cost. Over-the-counter (OTC) hearing aids offer a potential solution, incorporating self-fitting strategies via smartphone apps. Self-fitting strategies have been validated for Food and Drug Administration (FDA)-approved OTC hearing aids compared with prescription-based approaches.

The use of spirituality/religiosity by oncology nurse residents in nursing care.

Objectives: to analyze the use of spirituality/religiosity by oncology nurse residents in caring for patients with cancer.

Methods: a census, descriptive, sectional study, with 46 nurse residents from three public hospitals in Rio de Janeiro. Data collection took place between August 2020 and January 2021, using a sociodemographic questionnaire, including a question about the use of spirituality/ religiosity to deal with work situations.

Long-Term Outcomes of Self-Fit vs Audiologist-Fit Hearing Aids.

Importance: With rising interest in over-the-counter (OTC) hearing aids as an alternative to traditional audiologist-fit devices, understanding their long-term efficacy is crucial. However, given the novelty of the US Food and Drug Administration category of OTC hearing aids, minimal evidence currently supports their long-term efficacy.

Objective: To compare the long-term self-reported outcomes at 8 months of self-fit OTC hearing aids to the same hearing aids fit by audiologists.

Electrospun skin dressings for diabetic wound treatment: a systematic review.

Abstract: Diabetes mellitus is a metabolic disease characterized by persistent hyperglycemia associated with a lack of insulin production or insulin resistance. In diabetic patients, the capacity for healing is generally decreased, leading to chronic wounds. One of the most common treatments for chronic wounds is skin dressings, which serve as protection from infection, reduce pain levels, and stimulate tissue healing.

Genomic regions, candidate genes, and pleiotropic variants associated with physiological and anatomical indicators of heat stress response in lactating sows.

Background: Heat stress (HS) poses significant threats to the sustainability of livestock production. Genetically improving heat tolerance could enhance animal welfare and minimize production losses during HS events. Measuring phenotypic indicators of HS response and understanding their genetic background are crucial steps to optimize breeding schemes for improved climatic resilience.

Exploring the diversity and evolutionary strategies of prophages in Hyphomicrobiales, comparing animal-associated with non-animal-associated bacteria.

The Hyphomicrobiales bacterial order (previously Rhizobiales) exhibits a wide range of lifestyle characteristics, including free-living, plant-association, nitrogen-fixing, and association with animals (Bartonella and Brucella). This study explores the diversity and evolutionary strategies of bacteriophages within the Hyphomicrobiales order, comparing animal-associated (AAB) with non-animal-associated bacteria (NAAB). We curated 560 high-quality complete genomes of 58 genera from this order and used the PHASTER server for prophage annotation and classification.

Inducing molecular orientation in solution-processed thin films of fluorene-bithiophene-based copolymer: thermal annealing solvent additive.

A deep understanding of the factors influencing the morphology of thin films based on conjugated polymers is essential to boost their performance in optoelectronic devices. Herein, we investigated the electronic structure and morphology of thin films of the copolymer poly(9,9-dioctyl-fluorenyl--bithiophene) (F8T2) in its pristine form as well as samples processed with the solvent additive 1,8-diiodooctane (DIO) or post-processed through thermal annealing treatment. Measurements were carried out using angle-resolved S K-edge NEXAFS (near-edge X-ray absorption fine structure) in total electron yield (TEY) and fluorescence yield (FY) detection modes.

I-Poems: A Window Into the Personal Experiences of Family Caregivers of People Living With Advanced Cancer.

Background: To date, there is little understanding of how caring during advanced cancer can be a transformational experience for personal becoming for family caregivers (FCGs). FCGs experience personal becoming as they create their own meaning of health and illness and choose patterns relating to the self-identity of the past while reaching forward into the unknowns. Gaining greater insight into a potentially positive aspect of cancer caregiving can contribute to FCG well-being and quality of life.
