Expression of mutant TIE2 p.L914F during mouse development causes embryonic lethality and defects in vascular remodeling

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Sporadic venous malformation (VM) is associated with the hyperactivating p.L914F mutation in TIE2, a receptor tyrosine kinase essential for vascular development. This mutation is not found in hereditary VM, suggesting incompatibility with life when expressed during early vascular development.

Status epilepticus: Updates on mechanisms and treatments

open access: yesEpilepsia Open, EarlyView.
Abstract Status epilepticus (SE) consists of prolonged, self‐sustaining seizures and is a common neurological emergency that causes respiratory compromise and neuronal injury. Without prompt treatment, the seizures can become resistant to benzodiazepines, leading to the progressive evolution of established, refractory, and super‐refractory SE.

Risk Factors Influencing Conception Rate in Holstein Heifers before Artificial Insemination or Embryo Transfer

open access: yesMedia Peternakan, 2016
The objective of this study was to show the risk factors affecting the conception rate in Holstein heifers after synchronization of estrus. A total of 275 Holstein heifers housed in a free barn were used for the experiment. The herd was visited regularly

Bioclimatic, demographic and anthropogenic correlates of grizzly bear activity patterns in the Greater Yellowstone Ecosystem

open access: yesOikos, EarlyView.
Plasticity of diel activity rhythms may be a key element for adaptations of wildlife populations to changing environmental conditions. In the last decades, grizzly bears Ursus arctos in the Greater Yellowstone Ecosystem (GYE) have experienced notable environmental fluctuations, including changes in availability of food sources and severe droughts ...

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

open access: yesIEEJ 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,

Ovarian Dynamic in Ongole Grade Cattle After GnRH Injection in Ovsynch Protocol Based on Progesterone Device [PDF]

open access: yes, 2015
PO cattle have weaknesses to show clear estrus signs which cause difficulty in artificial insemination implementation. The present study was designed to obtain ovarian dynamic as effect of GnRH injection in ovsynch protocol based on progesterone ...

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

open access: yesWildlife 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 ...

A novel estrus-synchronization program for anestrous and cycling, suckled, beef cows [PDF]

open access: yes, 1997
We used four herds at three Kansas ranches to evaluate the potential of two new estrus synchronization strategies to increase estrus expression and fertility of 911 crossbred suckled beef cows.
