Longan flower water extract promotes sleep in mice via the serotonin–melatonin axis

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Longan (Dimocarpus longan) flower is an underutilized botanical byproduct rich in polyphenols with reported neuroprotective actions, yet its role in sleep regulation remains unclear. This study aimed to evaluate the sleep‐promoting effects of longan flower water extract (LFWE) and its underlying neurochemical mechanisms in vivo ...

Recurrence of Estrous Cycles in the Light-Induced Persistent Estrous Rats by Reserpine

Endocrinologia Japonica, 1976
Effect of continuous illumination (LL) on ovarian functions was compared at various ages between the rats exposed to LL from 70 days of age (LL-70) and exposed to LL from the day of birth (LL-0). LL-0 rats retained corpora lutea in their ovaries in higher incidence than LL-70 rats. Effect of reserpine on the restoration of cyclicity was studied in LL-0

Weight Loss After Obesity Disrupts Cognitive Flexibility Through Reinforcement Learning Strategies

Obesity, EarlyView.
ABSTRACT Objective Despite successful weight loss, many individuals with obesity regain weight, yet cognitive factors in the weight loss state remain unclear. Here, we tested whether obesity induces deficits in cognitive flexibility, a core component of reinforcement learning (RL), after body weight normalizes.

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

Oikos, 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 ...

Hypothalamic Expression of KiSS1 and RFamide-related Peptide-3 mRNAs during The Estrous Cycle of Rats [PDF]

International Journal of Fertility and Sterility, 2013
Kisspeptin and RFamide-related peptide-3 (RFRP-3) are known to affect GnRH/luteinizing hormone (LH) in several species, including the rat. It has been hypothesized that GnRH/LH changes during the rat estrous cycle may result from changes in the ...

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 ...

Longitudinal Testing of Exploratory Behaviour in Mice Reveals Stable Cognitive Traits Across the Adult Lifespan

Aging Cell, EarlyView.
Video tracking of mice demonstrated how exploratory performance at 4 months of age was a strong predictor of performance at 18 months of age. This longitudinal testing revealed that cognitive ability is a stable trait in adult mice that was associated with stable brain morphology and neuronal excitability.
