Pair housing presents an alternative to individual or larger group housing systems, though the effects of different pairing ages on calf welfare are not well understood. In this study, we examined the impact of pairing age on the performance, health, and behavior of dairy calves. A total of 140 Holstein female calves (n = 70 pairs) were used, paired at 3 ages: Early (6-7 d; 48 calves), Intermediate (29-30 d; 48 calves), and Late pairing (49-50 d; 44 calves).

Diabetic retinopathy (DR) is a serious diabetes complication that can lead to vision loss, making timely identification crucial. Existing data-driven algorithms for DR staging from digital fundus images (DFIs) often struggle with generalization due to distribution shifts between training and target domains. To address this, DRStageNet, a deep learning model, was developed using six public and independent datasets with 91,984 DFIs from diverse demographics.

SARS-Cov-2 is a corona virus that causes COVID-19 disease, a viral infection responsible for the pandemic decreed by the World Health Organization in March 2020. Angiotensin-converting enzyme 2 (ACE-2) functions as the main receptor for SARS-Cov-2. The study aimed to detect the expression of ACE-2 in the gastrointestinal tract, kidney, and lung in the rhesus monkeys and squirrel monkeys.

Several methods can be used to mitigate coastal erosion, and one of the leading solutions is known as beach nourishment (BN), which involves using dredged material for nourishment, adding sand to extend an eroding beach. Although it has many advantages, the environmental impacts of BN remain poorly understood, especially on plastic pollution, which had not been investigated until this study. We aimed to compare the abundance and distribution of microplastics (MPs) found in intertidal sediments and specimens of the bivalve mollusks Crassostrea brasiliana, Mytella strigata, Perna perna, and Tivela mactroides, collected in two beaches of Vitoria, Southeast of Brazil (da Costa et al.

Plants encounter various environmental stresses throughout development, including shade, high light, drought, hypoxia, extreme temperatures, and metal toxicity, all of which adversely affect growth and productivity. Organic acids (OAs), besides serving as intermediates in the tricarboxylic acid (TCA) cycle, play crucial roles in multiple metabolic pathways and cellular compartments, including mitochondrial metabolism, amino acid metabolism, the glyoxylate cycle, and the photosynthetic mechanisms of C4 and CAM plants. OAs contribute to stress tolerance by acting as root chelating agents, regulating ATP production, and providing reducing power for detoxifying reactive oxygen species (ROS).

Transmission-blocking vaccines (TBVs) targeting sexual-stage antigens represent a critical tool for malaria control and elimination through inhibiting parasite development within mosquitoes. P230, displayed on the surface of gametocytes and gametes, plays a crucial role in gamete fertilization and is one of the leading TBV candidates for both Plasmodium falciparum and P. vivax.

The escalating environmental impact of non-biodegradable plastic waste has intensified global efforts to seek sustainable alternatives, with biodegradable polymers from renewable sources emerging as a promising solution. This manuscript provides the current perspectives, challenges, and opportunities within the field of sustainable and biodegradable packaging. Despite a significant market presence of conventional non-biodegradable petrochemical-based plastics, there is a growing trend towards the adoption of bio-based polymers from renewable resources driven by environmental sustainability and regulatory measures.

Accurate calibration of finite element (FE) models is essential across various biomechanical applications, including human intervertebral discs (IVDs), to ensure their reliability and use in diagnosing and planning treatments. However, traditional calibration methods are computationally intensive, requiring iterative, derivative-free optimization algorithms that often take days to converge. This study addresses these challenges by introducing a novel, efficient, and effective calibration method demonstrated on a human L4-L5 IVD FE model as a case study using a neural network (NN) surrogate.

The use of exogenous phytase and vitamin D metabolites such as 25-hydroxycholecalciferol (25-OH-D) for poultry is well consolidated, but the potential for additive effects when supplementing both requires further investigation. This study investigated possible interactions between supplementation of 25-OH-D and high doses of phytase for broilers fed Ca- and P-deficient diets. A total of 1 200 one-d-old male broiler chicks were randomly allocated from one of four dietary treatments in a 2 × 2 factorial arrangement: 600 or 2 000 phytase units (FYT)/kg and with or without the inclusion of 25-OH-D at 69 µg/kg, with 12 replicates of 25 broilers each.

Phosphorus (P) movement in soils is influenced by flow velocities, diffusion rates, and several soil characteristics and properties. In acidic soils, P is tightly bound to soil particles, reducing its availability to plants. Organomineral fertilizers combine organic matter with mineral nutrients, enhancing P fertilization efficiency, and reducing environmental impacts.
