Effects of exercise on vascular remodelling and fetal growth in uncomplicated and abortion-prone mouse pregnancies.

Studies in humans and rodents show exercise in pregnancy can modulate maternal blood pressure, vascular volume, and placental efficiency, but whether exercise affects early uteroplacental vascular adaptations is unknown. To investigate this, CBA/J female mice mated with BALB/c males to generate healthy uncomplicated pregnancies (BALB/c-mated) or mated with DBA/2J males to generate abortion-prone pregnancies (DBA/2J-mated), were subjected to treadmill exercise (5 days/week, 10 m/min, 30 min/day for 6 weeks before and throughout pregnancy), or remained sedentary. In uncomplicated pregnancies, exercise caused symmetric fetal growth restriction in fetuses evidenced by reductions in fetal weight, crown-to-rump length, abdominal girth and biparietal diameter.

Accurate calculation of the content volume, density and original weight of museum curated eggs.

Worldwide museums hold collections of eggshells representing material for descriptive studies. However, an obstacle to this is the lack of information about the original contents and weight of the entire egg (W). This study aimed to fill this gap though development of a methodological mechanism for calculating the volume of the egg interior (V), its density (D) and W.

Biochemical analysis showed increased serum concentration of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine and urea in comparison to the normal reference range.

Beyond the herd: investigating livestock feeding strategies in the Iron Age Iberian Peninsula (3rd c. BC) through a multi-isotope analysis.

Unlabelled: During the Iron Age, north-eastern Iberian communities relied on crop cultivation and animal husbandry for their subsistence. The latter was mainly focused on caprine, with sheep being prominent due to their suitability to the Mediterranean climate, orography, and environment. Despite the pivotal role of sheep in livestock husbandry, information on Iberian communities' feeding strategies for this species is limited.

Development of peptone-based serum-free media to support Vero CCL-81 cell proliferation and optimize SARS-CoV2 viral production.

Background: Developing an optimal media for Vero cell lines is crucial as it directly influences cell survival, proliferation, and virus production. The use of serum in cell culture raises safety concerns in biological production. The United States Food and Drug Administration (FDA) and the European Medicines Agency have implemented stricter regulations on the use of animal-derived components in commercial protein manufacturing to ensure patient safety.

Pear-Shaped Eggs Evolved to Maximize the Surface Area-to-Volume Ratio, Increase Metabolism, and Shorten Incubation Time in Birds.

Bird eggs can be spherical, ellipsoid, ovoid, or pear-shaped (pyriform), the latter being the most complex. There is however no unambiguous evolutionary/adaptive explanation for this final, exotic shape. We hypothesized that pyriform eggs have a larger surface area-to-volume ratio (S/V) that may be a criterion for increased embryo metabolism.

Identification of key genes and variants associated with boar sperm freezability using whole genome resequencing.

Cryopreservation induces various cryodamages to the structural or functional aspects of boar sperm, resulting in the deterioration of sperm quality. The extent of cryodamages varies significantly among different individual boars. In our study, 50 boars with either good sperm freezability (GSF) or poor sperm freezability (PSF) were selected from a population of 402 boars.

Functional effects of BMPR1B in porcine endometrium provides novel insights into the high fecundity of Taihu pigs.

Litter size in pigs is affected by factors such as ovulation number, embryonic survival, and uterine environment conditions. Endometrial epithelial and stromal cells represent the first site of contact between the embryo and sows; therefore, dynamic changes in the growth and development of these cells are among the major factors affecting the intrauterine environment and implantation. Bone morphogenetic protein receptor type-1B (BMPR1B) is a receptor of the bone morphogenetic protein (BMP) family that has been identified as a candidate gene for reproductive traits in pigs.

Transcriptional analysis reveals the suppression of RAD51 and disruption of the homologous recombination pathway during PEDV infection in IPEC-J2 cells.

PEDV is a highly contagious enteric pathogen that can cause severe diarrhea and death in neonatal pigs. Despite extensive research, the molecular mechanisms of host's response to PEDV infection remain unclear. In this study, differentially expressed genes (DEGs), time-specific coexpression modules, and key regulatory genes associated with PEDV infection were identified.

The role of lignin in 17β-estradiol biodegradation: insights from cellular characteristics and lipidomics.

17β-estradiol (E2) is an endocrine disruptor, and even trace concentrations (ng/L) of environmental estrogen can interfere with the endocrine system of organisms. Lignin holds promise in enhancing the microbial degradation E2. However, the mechanisms by which lignin facilitates this process remain unclear, which is crucial for understanding complex environmental biodegradation in nature.

Performance, meat quality and blood parameters in four strains of organic broilers differ according to range use.

Chicken meat production in organic systems involves free-range access where animals can express foraging and locomotor behaviours. These behaviours may promote outdoor feed intake, but at the same time energy expenditure when exploring the outdoor area. More generally, the relationship of range use with metabolism, welfare including health, growth performance and meat quality needs to be better understood.

Brassica rapa L. polysaccharide mitigates hypobaric hypoxia-induced oxidation and intestinal damage via microbiome modulation.

The high-altitude, low-pressure, and hypoxia environment poses a significant threat to human health, particularly causing intestinal damage and disrupting gut microbiota. This study investigates the protective effects of Brassica rapa L. crude polysaccharides (BRP) on intestinal damage in mice exposed to hypobaric hypoxic conditions.

The role of visfatin in peripheral immune organs and intestines of weaned piglets under lipopolysaccharide induced immune stress.

To investigate the regulatory mechanisms and pathways of visfatin under immune stress injury in weaned piglets, we established a lipopolysaccharide-induced immune stress model in weaned piglets to study how visfatin affects peripheral immune organs and intestinal function. The results revealed that visfatin improved the inflammatory response in immune-stressed weaned piglets by reducing the levels of pro-inflammatory cytokines interleukin-1β, interleukin-6 and monocyte chemoattractant protein-1, as well as decreasing the neutrophil/lymphocyte ratio. Visfatin ameliorated oxidative stress in piglets by promoting the expression of superoxide dismutase and glutathione peroxidase.
