Neuromolecular Basis of Impaired Conditioned Taste Aversion Acquisition in Valproate-Induced Rat Model of Autism Spectrum Disorder Open
Background/Objectives: Autism spectrum disorder (ASD), defined by social, behavioral, and cognitive anomalies, is also associated with dysregulated appetite. ASD individuals, often described as “picky eaters”, exhibit restricted dietary pr…

From Processed Foods to Ultraprocessed Foods: Evolution of an Industry Model and Impact on Dietary Quality, Health, and Society Open
The impact of food technology and product development on the nutritional quality of foods is discussed in the context of food classification schemes, clinical research, and sociocultural studies. Food processing operations are analyzed in …

Using Less Processed Food to Mimic a Standard American Diet Does Not Improve Nutrient Value and May Result in a Shorter Shelf Life at a Higher Financial Cost Open
Less-processed menus can have comparable diet quality with more-processed menus although being more costly and less shelf stable.

Ultra‐processed foods: Processing versus formulation Open
The four‐tiered NOVA food classification defines foods based on their degree of processing and ranges from native unprocessed foods to so‐called “ultra‐processed” foods. Recent publications have suggested that foods classified as ultra‐pro…

Chronic Intermittent Sucrose Consumption Facilitates the Ability to Discriminate Opioid Receptor Blockade with Naltrexone in Rats Open
The opioid antagonist naltrexone (NTX) decreases intake of preferred diets in rats at very low doses relative to doses needed to decrease intake of “bland” laboratory chow. In the absence of an opioid agonist, NTX is not discriminable usin…

Acute Hypophagia and Changes in c-Fos Immunoreactivity in Adolescent Rats Treated with Low Doses of Oxytocin and Naltrexone Open
A recent case report has shown that an adjunctive oxytocin + naltrexone (OT + NTX) treatment promoted more robust hypophagia and body weight reduction than OT alone in an adolescent male with hypothalamic obesity after craniopharyngioma re…

Adjustment of Whey:Casein Ratio from 20:80 to 60:40 in Milk Formulation Affects Food Intake and Brainstem and Hypothalamic Neuronal Activation and Gene Expression in Laboratory Mice Open
Adjustment of protein content in milk formulations modifies protein and energy levels, ensures amino acid intake and affects satiety. The shift from the natural whey:casein ratio of ~20:80 in animal milk is oftentimes done to reflect the 6…

Effect of Oxytocin on Hunger Discrimination Open
Centrally and peripherally administered oxytocin (OT) decreases food intake and activation of the endogenous OT systems, which is associated with termination of feeding. Evidence gathered thus far points to OT as a facilitator of early sat…

Palatability of Goat’s versus Cow’s Milk: Insights from the Analysis of Eating Behavior and Gene Expression in the Appetite-Relevant Brain Circuit in Laboratory Animal Models Open
Goat’s (GM) and cow’s milk (CM) are dietary alternatives with select health benefits shown in human and animal studies. Surprisingly, no systematic analysis of palatability or preference for GM vs. CM has been performed to date. Here, we p…

Discriminative Stimulus Effects of Naltrexone and Haloperidol in Rats with Chronic, Intermittent Access to Sucrose Open
Previous research demonstrated chronic, intermittent sucrose access increased endorphin and dopamine function, and naltrexone elicited some withdrawal‐like behaviors in rats. We determined the naltrexone serves as a discriminative stimulus…

Tim Bartness, Ph.D. (1953-2015) Open
Tim Bartness (Fig. 1) was a friend, mentor, collaborator and leader to many scientists, younger and older, across a
variety of disciplines. He died September 24, 2015 at the age of 62 after a one-year battle with multiple myeloma.
