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

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
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,

Monitoring the effects of ovariectomy on seasonal movement behavior in suburban female white‐tailed deer using internet of things‐enabled devices

Wildlife Biology, EarlyView.
Abundant deer populations often cause conflicts in suburban communities, yet traditional population reduction methods, such as controlled hunting, can be challenging to implement. Fertility control, specifically through ovariectomy, can limit reproduction and reduce populations in certain settings, but its effect on movement behavior remains poorly ...

Luteinizing hormone receptor knockout mouse: What has it taught us?

Andrology, EarlyView.
Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...

Recovery from Age-Related Infertility under Environmental Light-Dark Cycles Adjusted to the Intrinsic Circadian Period

Cell Reports, 2015
Female reproductive function changes during aging with the estrous cycle becoming more irregular during the transition to menopause. We found that intermittent shifts of the light-dark cycle disrupted regularity of estrous cycles in middle-aged female ...

Sex‐specific impact of repeated adolescent vapour exposure to JWH‐018 on dopamine response, behaviour and pharmacokinetics across adolescence and adulthood

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Alarming trends show that vaping e‐cigarettes containing synthetic cannabinoid receptor agonists, such as JWH‐018, is increasing among youth. However, the effects of these trends are unclear in both sexes. We therefore characterized the neuropharmacological effects of adolescent JWH‐018 inhalation in male and female rats.

Validation of a mathematical model of the bovine estrous cycle for cows with different estrous cycle characteristics

Animal, 2017
A recently developed mechanistic mathematical model of the bovine estrous cycle was parameterized to fit empirical data sets collected during one estrous cycle of 31 individual cows, with the main objective to further validate the model.

Cytochrome P450 1A1 influences obesity‐induced pulmonary hypertension

British Journal of Pharmacology, EarlyView.
Background and Purpose The contribution of obesity to pulmonary arterial hypertension (PAH) pathophysiology remains poorly understood. Adipose tissue synthesises estrogens via cytochrome P450 (CYP) 19A1 (aromatase), whereas circulating estrogens are metabolised in the lung by CYP1A1.

Improving mare fertility via broad ligament imbrication with barbed suture and intracorporeal suturing device

Equine Veterinary Education, EarlyView.
Summary In this short case series, we report the outcome of four mares undergoing mesometrial imbrication (uteropexy) using barbed suture and an automated laparoscopic suturing device. Medical records of four mares infertile because of delayed uterine clearance (DUC) that underwent laparoscopic mesometrial imbrication to elevate a vertically positioned
