Biology and Management of Male‐Bodied Athletes in Elite Female Sports

open access: yesDrug Testing and Analysis, EarlyView.
Graphical representation of the relationships of transgender and XY DSDF as male‐bodied athletes along the binary dimensions of biological sex. ABSTRACT The physical advantages in elite power sports that allow men to surpass women are derived from the experience of male puberty.

A head start: The relationship of placental factors to craniofacial and brain development

open access: yesDevelopmental Dynamics, EarlyView.
Abstract In recent years, the importance of placental function for fetal neurodevelopment has become increasingly studied. This field, known as neuroplacentology, has greatly expanded possible etiologies of neurodevelopmental disorders by exploring the influence of placental function on brain development.

Roles for the Uptake\u3csub\u3e2\u3c/sub\u3e Transporter OCT3 in Regulation of Dopaminergic Neurotransmission and Behavior [PDF]

open access: yes, 2019
Transporter-mediated uptake determines the peak concentration, duration, and physical spread of released monoamines. Most studies of monoamine clearance focus on the presynaptic uptake1 transporters SERT, NET and DAT.

Home Cage Compared with Induction Chamber for Euthanasia of Laboratory Rats [PDF]

open access: yes, 2018
This study compared behavioral and physiologic changes in Sprague-Dawley and Brown Norway rats that were euthanizedby using a 30% volume displacement rate of CO2 in either their home cage or an induction chamber; rats euthanized in thehome cage were ...

Corticosterone - an anxiogenic or an anxiolytic agent?

open access: yesJournal of Pharmacy and Pharmacology, 1979
Abstract Corticosterone (3–12 mg kg−1, i.p., giving rise to plasma corticosterone concentrations from 26.7 to 89.0 μg/100 ml) failed to have a significant anxiogenic action. Instead, corticosterone (3 mg kg−1) had a significant anxiolytic effect in the social interaction test of anxiety.

Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

open access: yesEcography, EarlyView.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

Differential Effects of Psychological and Physical Stress on the Sleep Pattern in Rats [PDF]

open access: yes, 2007
In the present study, we investigated the acute effects of 2 different kinds of stress, namely physical stress (foot shock) and psychological stress (non-foot shock) induced by the communication box method, on the sleep patterns of rats.

Prenatal Stress Induces High Anxiety and Postnatal Handling Induces Low Anxiety in Adult Offspring: Correlation with Stress-Induced Corticosterone Secretion

open access: yesJournal of Neuroscience, 1997
It is well known that the hypothalamo-pituitary-adrenal (HPA) axis is altered by early environmental experiences, particularly in the perinatal period.

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Epigallocatechin-3-gallate confers protection against corticosterone-induced neuron injuries via restoring extracellular signal-regulated kinase 1/2 and phosphatidylinositol-3 kinase/protein kinase B signaling pathways.

open access: yesPLoS ONE, 2018
Extensive studies suggested epigallocatechin-3-gallate (EGCG) has significant neuroprotection against multiple central neural injuries, but the underlying mechanisms still remain poorly elucidated.
