The role played by adrenergic system in water intake, especially food intake, has long been known in mammals. In avian species, there have been many experiments exploring the effects of the adrenergic system in different sites in the central nervous system in meat- and egg-type poultry. This study was designed to examine the possible effects of intralateral hypothalamic area (ILHy) microinjections of a beta-adrenergic agonist, isoproterenol, and a beta-adrenoceptor blocker, propranolol, on food and water intake in 3-h food-deprived and 3-h water-deprived broiler cockerels. Our findings suggest that the beta-adrenergic system directly affects food especially water intake in broilers. Although isoproterenol significantly (P < or = 0.05) decreased food intake for the first 15 min, it reduced food intake during the experiment. Isoproterenol reduced water intake significantly (P < or = 0.05), which was abolished by pretreatment with propranolol. It is proposed that beta-adrenoceptors in LHy play a direct and indirect role in the regulation of food especially water intake in broiler cockerels.

Examining Electronic Nicotine Delivery System (ENDS) Cue Reactivity Using a Remote Platform: Cigarette and ENDS Desire in Dual Users.
Nicotine Tob Res

University of Chicago, Department of Psychiatry and Behavioral Neuroscience, Chicago, IL.
Introduction: Prior research shows that in-person exposure to electronic nicotine delivery systems (ENDS) use increases desire for cigarettes and ENDS. However, less is known about the impact of cues delivered during remote interactions. This study extends previous in-person cue work by leveraging a remote confederate-delivered cue-delivery paradigm to evaluate the impact of dual nicotine vaping (vs.

Moreover, although daily diary and experimental studies among civilians have found negative associations between alcohol use and sleep, these patterns change with consecutive days of drinking and may differ for those with insomnia. This study measured (a) acute and cumulative day-level associations between sleep and alcohol use among heavy-drinking US veterans and (b) the extent to which insomnia moderates these associations.

Functionalized polymer membrane electrodes based multichannel sensor is used as an electronic tongue to monitor the drinking water (DW) quality simply by measuring the surface electric potential with respect to Ag/AgCl reference electrode in 1 mM aqueous KCl. Changes of minute concentration of dissolved minerals greatly affected the surface potential of the sensor. The three-channel sensor device (electronic tongue) is made by using three different functionalized polymer membrane electrodes, namely, phosphorylated hexadecyl trimethyl ammonium chloride modified polyvinyl alcohol-polyacrylic acid membrane; phosphorylated and crosslinked polyvinyl--ethylene membrane; phosphorylated and crosslinked polyvinyl alcohol membrane, as working electrodes and a Ag/AgCl reference electrode.

Background: The current subclassification of steatotic liver disease (SLD) relies on validated questionnaires, such as Alcohol Use Disorders Identification Test (AUDIT) and Lifetime Drinking History (LDH), which, while useful, are impractical and lack precision for their use in routine clinical practice. Phosphatidylethanol (PEth) is a quantitative, objective alcohol biomarker with high sensitivity and specificity.
Aims: To assess the diagnostic accuracy of PEth for differentiating metabolic dysfunction and alcohol-associated liver disease (MetALD) from metabolic dysfunction-associated steatotic liver disease (MASLD) in a large, population-based, prospective, multiethnic cohort of individuals with overweight or obesity.
