Whey-Adapted versus Natural Cow's Milk Formulation: Distinctive Feeding Responses and Post-Ingestive c-Fos Expression in Laboratory Mice.

The natural 20:80 whey:casein ratio in cow's milk (CM) for adults and infants is adjusted to reflect the 60:40 ratio of human milk, but the feeding and metabolic consequences of this adjustment have been understudied. In adult human subjects, the 60:40 CM differently affects glucose metabolism and hormone release than the 20:80 CM. In laboratory animals, whey-adapted goat's milk is consumed in larger quantities.

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.

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 60:40 ratio of human milk. Studies show that 20:80 versus 60:40 whey:casein milks differently affect glucose metabolism and hormone release; these data parallel animal model findings.

Goat and cow milk differ in altering microbiota composition and fermentation products in rats with gut dysbiosis induced by amoxicillin.

Antibiotics are effective treatments for bacterial infections, however, their oral administration can have unintended consequences and may alter the gut microbiota composition. In this study, we examined the influence of antibiotics on the induction of gut dysbiosis and then evaluated the potential of cow and goat milk to restore the microbiota composition and metabolism in newly weaned rats. In the first study (gut dysbiosis model), rats were treated with amoxicillin, a mixture of antibiotics (ampicillin, gentamicin and metronidazole) or no antibiotics (control).

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.

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.

N-carboxymethyllysine in nutritional milk formulas for infants.

Production of infant formulas involves high temperature processing for microbiological safety. However, heat processes generate Advanced Glycation End-products (AGEs), including N-carboxymethyllysine (CML) formed between lysine and lactose. Formulas manufactured from cow or goat milk, with or without whey adjustment, or hydrolysates of cow whey proteins, were tested for CML levels using a commercially available ELISA kit.

Digestive Responses to Fortified Cow or Goat Dairy Drinks: A Randomised Controlled Trial.

Fortified milk drinks are predominantly manufactured from bovine (cow) sources. Alternative formulations include those prepared with hydrolysed bovine milk proteins or from alternate species, such as caprine (goat) milk. Currently, there is little data on protein digestive and metabolic responses following ingestion of fortified milk drinks.

Identification of central mechanisms underlying anorexigenic effects of intraperitoneal L-tryptophan.

A free essential amino acid, L-tryptophan (TRP), administered through a diet or directly into the gut, decreases food intake by engaging neural mechanisms. The ability of intragastric TRP to cross into the general circulation and through the blood-brain barrier, at least partly underlies hypophagia. It is unclear although, whether TRP's anorexigenic effects and accompanying neural processes occur in the absence of the initial action of TRP on the gut mucosa.

Intragastric preloads of l-tryptophan reduce ingestive behavior via oxytocinergic neural mechanisms in male mice.

Human and laboratory animal studies suggest that dietary supplementation of a free essential amino acid, l-tryptophan (TRP), reduces food intake. It is unclear whether an acute gastric preload of TRP decreases consumption and whether central mechanisms underlie TRP-driven hypophagia. We examined the effect of TRP administered via intragastric gavage on energy- and palatability-induced feeding in mice.

Subjective experience of recovery from schizophrenia-related disorders and atypical antipsychotics.

Aims: This article investigates the subjective experience of the process of improvement and recovery from the point of view of persons diagnosed (according to research diagnostic criteria) with schizophrenia and schizo-affective disorders.

Methods: A community study of persons using psychiatric services was conducted for a sample of ninety subjects taking atypical antipsychotic medications. Sociodemographic data and clinical ratings were collected to complement the qualitatively developed Subjective Experience of Medication Interview (SEMI), which elicits narrative data on everyday activities, medication and treatment, management of symptoms, expectations concerning recovery, stigma, and quality of life.
