Toward a Genetic Signature of Resistance to Activity‐Based Anorexia in Striatal Projecting Cortical Neurons

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Converging evidence from neuroimaging studies and genome‐wide association study (GWAS) suggests the involvement of prefrontal cortex (PFC) and striatum dysfunction in the pathophysiology of anorexia nervosa (AN). However, identifying the causal role of circuit‐specific genes in the development of the AN‐like phenotype remains ...

Fetal liver blood flow distribution: role in human developmental strategy to prioritize fat deposition versus brain development [PDF]

open access: yes, 2012
Among primates, human neonates have the largest brains but also the highest proportion of body fat. If placental nutrient supply is limited, the fetus faces a dilemma: should resources be allocated to brain growth, or to fat deposition for use as a ...

The diel niche of brown bears: constraints on adaptive capacity in human‐modified landscapes

open access: yesEcography, EarlyView.
Diel activity rhythms, representing the behavioral pattern of the sleep–wake cycle, may be adjusted by wildlife in response to changes in environmental conditions. An increase in nocturnality is typically recognized as an adaptive strategy to segregate from humans and mitigate heat stress. Numerous studies have investigated spatial patterns and habitat

Effect of local hand cooling on thermoregulation and rhythm of cardiogram of students from hot climate

open access: yesRUDN Journal of Medicine, 2014
The article presents data on changes in thermoregulation and heart rate variability due to local cooling of the hand from hot climate zone natives. Shown that a significant number of peripheral vascular spasms in response to local cooling do not occur ...

Brain serotonin and dopamine modulators, perceptual responses and endurance performance during exercise in the heat following creatine supplementation [PDF]

open access: yes, 2008
Background:The present experiment examined the responses of peripheral modulators and indices of brain serotonin (5-HT) and dopamine (DA) function and their association with perception of effort during prolonged exercise in the heat after creatine (Cr ...

Progress of non‐motor symptoms in early‐onset Parkinson's disease

open access: yesIbrain, EarlyView.
This study reviews the research progress related to non‐motor symptoms (NMS) in patients with early onset Parkinson's disease (EOPD), including neuropsychiatric symptoms, autonomic dysfunction, sleep disorders, and sensory disorders and also summarizes the characteristics of NMS in the genetic form of Parkinson's disease (PD).

Thermoregulation Effects of Phoneutria nigriventer Isolated Toxins in Rats

open access: yesToxins
Body temperature is primarily regulated by the hypothalamus, ensuring proper metabolic function. Envenomation by Phoneutria nigriventer can cause symptoms such as hypothermia, hyperthermia, sweating, and shivering, all related to thermoregulation.

Effect of Ambient Temperature on Body Temperature and Rest Metabolic Rate in Apodemus chevrieri During Postnatal Development [PDF]

open access: yesJournal of Stress Physiology & Biochemistry, 2014
In order to investigate the ability of constant temperature and thermoregulation in Apodemus chevrieri, body temperature and rest metabolic rate (RMR) were measured during postnatal development (1~42 day) when the A.
