Reentrainment following phase shifts of the light-dark (LD) cycle is accelerated in Octodon degus in the presence of olfactory social cues (i.e., odors) produced by conspecifics. However, not all odors from conspecifics were effective in facilitating reentrainment after a phase advance. In the current experiments, we examined whether nonanimal odors, odors from another species, or conspecific o...

Our previous study in male rats demonstrated that bilateral administration of flutamide, an androgen receptor (AR) antagonist, into the posterodorsal medial amygdala (MePD) increased the time sniffing male odors to as high as that sniffing estrous odors, eliminating the preference for estrous odors over male odors. This made us speculate that under blockade of AR in the MePD, testosterone-deriv...

1. The influence of ethanol on the metabolism of livers from fed and starved rats has been studied in liver-perfusion experiments. Results have been obtained on oxygen consumption and carbon dioxide production, on glucose release and uptake by the liver and on changes in the concentrations of lactate and pyruvate and of beta-hydroxybutyrate and acetoacetate in the perfusion medium. 2. Oxygen co...

People today spend most of their time indoors; many use fragrances in closed restrooms and bathrooms at home public spaces for masking odors. However, volatile organic compounds (VOCs) that are emitted from indoor have been reported recent years to pose a risk health. In this work, microneedle trap samplers (NTSs) were fabricated, packed with sulfonated divinylbenzene (SDVB) adsorbents, used pa...

Dynamic Controlled Atmosphere (DCA) is beneficial in maintaining specific quality parameters but, due to the extreme oxygen levels applied, can cause adverse effects on fruit by inducing excessive anaerobic metabolism and production of off-flavors. The metabolic adaptation responses apples (Malus domestica Borkh.) cv. Red Delicious static or dynamic concentrations (0.3 0.8%, with sequential shi...

Accumulating evidence indicates that selective antagonism of kappa opioid receptors may provide therapeutic benefit in the treatment of major depressive disorder, anxiety disorders, and substance use disorders. LY2456302 is a high-affinity, selective kappa opioid antagonist that demonstrates >30-fold functional selectivity over mu and delta opioid receptors. The safety, tolerability, and pharma...

Previous work has shown that there is a relationship between the degree of deterioration of cane and the amount of ethanol present. The use of an ethanol detector for identifying stale cane was investigated at Noodsberg. This tool will enable the cane quality controller to identify areas where cane delays occur and implement appropriate action. The detector uses the infrared absorbance of ethan...

As hunter-gatherers, humans used their sense of smell to identify plants and animals, find way within a foraging area, or distinguish each other by gender, age, kinship, social dominance. Because women gathered while men hunted, the sexes evolved different sensitivities plant animal odors. They also ended up emitting Male odors served intimidate rival males assert With rise farming sedentism, n...

PURPOSE To evaluate brain activity associated with sexual arousal, fully conscious male marmoset monkeys were imaged during presentation of odors that naturally elicit high levels of sexual activity and sexual motivation. MATERIAL AND METHODS Male monkeys were lightly anesthetized, secured in a head and body restrainer with a built-in birdcage resonator and positioned in a 9.4-Tesla spectrome...
