No impact of sex or testosterone treatment on wheel running in a rat model of inflammatory bowel disease - Biology of Sex Differences Background Sex differences in inflammatory bowel disease (IBD) have been reported in humans, and gonadal steroid hormones are implicated in these sex differences. Although pain is a primary complaint ...

Did you know? Bowel inflammation cuts wheel running and body weight in rats. But males, females, and testosterone-treated females all rebounded similarly. No sex or testosterone effect… but higher estradiol = worse outcomes. Hormones matter—just not the ones you’d expect! #ossd #sabv

Sex differences in AMPA receptor trafficking proteins - Biology of Sex Differences AMPA receptors are a type of ionotropic glutamate receptor that is important for fast excitatory neurotransmission. healthy brain function. Glutamate signaling is regulated, in part, by the traffickin...

Did you know? The neurotransmitter glutamate is implicated in memory, schizophrenia, and depression. However, how it works comes largely from male research. Female subjects must be included in future studies to see how it functions in both sexes, leading to better treatments. #ossd #sabv

Egr1 is a sex-dependent regulator of neuronal chromatin, structural plasticity, and behaviour - Nature Communications Molecular drivers of sex-specific brain plasticity are unknown. Here, authors show estrogen-driven Egr1 controls chromatin accessibility sex-dependently, driving gene expression, structural plasticity...

Did you know? A hormone-responsive gene in the brain can reshape brain structure and behavior differently in males and females.

These findings help explain why brain disorders can affect men and women differently-and why treatments may need to be sex-specific. #Neuroscience #SABV

Brain-wide neuron quantification toolkit reveals strong sexual dimorphism in the evolution of fear memory Fear responses are functionally adaptive behaviors that are strengthened as memories. Indeed, detailed knowledge of the neural circuitry modulating fe…

Did you know that posttraumatic stress disorder is roughly twice as prevalent in women compared to men and that fear memories are stored in sex-biased networks, which may explain these differences? #sabv #ossd #sexdifferences #humanhealth #ptsd #fear #learningandmemory

Sex dependency of subconscious visual perception - Biology of Sex Differences Males are more susceptible to neurodevelopmental cognitive deficits in their perception of visual information. Subliminally-presented visual stimuli might be subconsciously perceived and consequently ...

Sex-specific neural responses to smartphone cues in young adults - Biology of Sex Differences Problematic smartphone use has been associated with altered reward and executive control network activity, yet potential sex differences in the underlying neural mechanisms remain insufficiently under...

Did you know? 📱 When seeing smartphone cues in an MRI, young men show stronger activation in attention and control brain networks: The more activated, the higher their craving. Whereas women show a different pattern: Brain activity decreasing as problematic use increases. #sabv #ossd

Sex-specific gonadal transcriptome during early development of Siberian sturgeon - Biology of Sex Differences Background Sex determination and differentiation are complex processes shaped by a wide variety of molecular factors. In contrast to teleost species, many aspects of these processes remain poorly unde...

Throwing like a girl: a critique of past approaches and an illustrated proposal for a path forward - Biology of Sex Differences Background The phrase “Throwing like a girl” persists in popular culture and in scientific research as a trope about biological differences between males and females. In this review/theoretical paper ...

Did you know? “Throwing like a girl” isn’t biology. Fausto-Sterling found that infants who start ball play earlier (often boys) practice from stable positions and throw farther sooner. Timing and practice, not sex, shape throwing skill. #SABV #OSSD #sexdifferences

Sex differences in noradrenergic regulation of the medial prefrontal cortex in mice - Biology of Sex Differences Background Norepinephrine (noradrenaline; NE) is a stress signal released from the locus coeruleus (LC) into the prefrontal cortex (PFC) to govern arousal, attention, and cognition. The LC is sexually...

Did you know female brains have stronger norepinephrine projections from locus coeruleus to prefrontal cortex? BUT prefrontal neurons are less sensitive to signaling than in males! This study found sex differences in this stress and decision-making circuitry. #sabv #ossd #sexdifferences #humanhealth

Establishment of sex-specific liver transcriptomes and H3K9me3 profiles during sexual maturity: the impact of maternal obesity - Biology of Sex Differences Background The escalating prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) is closely linked to rising obesity rates. Maternal obesity (MO) is associated with increased s...

A mother's diet can leave lasting epigenetic fingerprints on her offspring's liver, altering how genes are expressed, long after the young eat healthy again. These changes can disrupt metabolism sex-specifically, potentially raising lifelong risk for fatty liver disease. #sabv #ossd #sexdifferences

Impact of continuous testosterone exposure on reproductive physiology, activity, and pain-related behavior in young adult female rats Testosterone may reduce pain in cisgender women and transgender men. Rodents can provide a useful model for investigating physiological effects of hor…

Giving female rats testosterone at male-like levels helped them bounce back faster after surgery, but it didn't actually make them experience less pain. Testosterone boosted recovery, not pain resistance! #sabv #ossd #sexdifferences #humanhealth www.sciencedirect.com/science/arti...
