Transgenerational effect of prenatal stress on behavior and lipid peroxidation in brain structures of female rats during the estral cycle

Вавиловский журнал генетики и селекции
The effect of stress in pregnant female Wistar rats on the behavior and lipid peroxidation (LP) in the neocortex, hippocampus and hypothalamus in the female F2 generation during the ovarian cycle was investigated. We subjected pregnant females to daily 1-

Acute exercise‐induced lipolysis and increase in levels of fatty acid esters of hydroxy fatty acids in adipose tissue are impaired in obese and aged mice

Experimental Physiology, EarlyView.
Abstract Improving adipose tissue (AT) metabolism through exercise might increase production of lipokines from the fatty acid esters of hydroxy fatty acids (FAHFA) family. Although exercise training can increase insulin sensitivity and levels of specific FAHFA in AT and the circulation in humans, the effects of acute exercise on FAHFA levels remain ...

Ovarian hormone loss modifies the nucleic acid cargo of circulating extracellular vesicles and skeletal muscle metabolism after acute exercise in rats

Experimental Physiology, EarlyView.
Abstract Loss of ovarian hormones (i.e., menopause) leads to negative effects on metabolic health. While exercise offers significant benefits, it seems to be insufficient to completely reverse these changes. The mechanisms by which exercise conveys the effects throughout the body are still poorly understood.

Thyroid antibody positivity in pregnancy is associated with altered reproductive hormone concentrations and placental growth in Lewis rats

The Journal of Physiology, EarlyView.
Abstract figure legend Thyroid antibody positivity (TAb+) in pregnancy is associated with adverse pregnancy outcomes, but the mechanisms are unclear. This study developed a rodent model of TAb+ in pregnancy, induced prior to mating so that TAb+ exposure occurred throughout the pregnancy. TAb+ did not alter thyroid hormone concentrations and had minimal

Portable Radar for Noncontact Heart Rate Monitoring and Estrus Detection in Dairy Cows

IEEJ Transactions on Electrical and Electronic Engineering, Volume 21, Issue 9, Page 1390-1403, September 2026.
This study introduces a portable radar system for real‐time monitoring of respiratory and heart rates in dairy cows. It uses millimeter‐wave Frequency Modulated Continuous Wave (FMCW) radar to perform noncontact physiological sensing, reducing behavioral disturbance. The radar system's design prioritizes portability, cost‐effectiveness, and robustness,

Household‐Based Epidemiology of Bovine Ixodid Tick Infestation and Associated Risk Factors in Endamehoni, Raya‐Azebo and Enderta Districts, Tigray Region, Northern Ethiopia

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Tick infestation affected 41.5% of cattle in Tigray, with Rhipicephalus species predominating. Infestation was strongly associated with poor housing, poor body condition and management practices, whereas limited awareness of tick‐borne diseases highlights the need for targeted control strategies informed by species‐specific attachment‐site preferences.

Ultrastructure of the Epithelium of the Vaginal Complex During the Proestrus and Luteal Phases of the Estrous Cycle in the White‐Eared Opossum (Didelphis albiventris)

Anatomia, Histologia, Embryologia, Volume 55, Issue 5, September 2026.
ABSTRACT The white‐eared opossum (Didelphis albiventris) is a Neotropical opportunistic marsupial widely distributed in the Brazilian territory, occupying both open and forest formations. The anatomy of the marsupial female genital tract consists of two ovaries, oviducts, double uterus, two lateral vaginae, vaginal sinus and a urogenital sinus. The two

Testicular SIRT1 Loss Reveals an Aging‐Like Proteomic Landscape and Precipitates Reproductive Deterioration

Andrology, Volume 14, Issue 6, Page 1579-1589, September 2026.
ABSTRACT Background Advanced paternal age is associated with reduced male fertility and testicular dysfunction. Among the molecular regulators involved in aging, SIRT1, a NAD+‐dependent deacetylase, plays a pivotal role in maintaining oxidative balance and cellular homeostasis.
