Innovative cooking techniques in a hospital food service: Effects on the quality of hospital meals.

Objectives: The hospital catering service plays a decisive role in responding to clinical and nutritional needs and in providing food that is acceptable to patients. Unfortunately, at the moment, most hospital catering services provide a service deemed insufficient by users and are burdened by a high proportion of food waste that may negatively affect the nutritional and clinical status of patients. The aim of this study was to verify the efficacy of the NI-Nutritional Intelligence project in improving the nutritional and sensorial quality of hospital meals.

The yogurt amino acid profile's variation during the shelf-life.

Objective: To analyze the yogurt amino acid profile starting from marketing through the whole shelf-life. The evaluation of the proteolytic activity of Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus salivarius subsp.

Postharvest dehydration of wine white grapes to increase genistein, daidzein and the main carotenoids.

Wine white grape bunches of the Grechetto variety were dehydrated at 10, 20 and 30°C, RH 45% and forced air ventilation of 1.5m/s. Chemical and metabolic changes due to the effect of dehydration were studied at various stages of weight loss: 10%, 20%, 30% and 40%.

Type 2 metabotropic glutamate (mGlu) receptors tonically inhibit transmitter release in rat caudate nucleus: in vivo studies with (2S,1'S,2'S,3'R)-2-(2'-carboxy-3'-phenylcyclopropyl)glycine, a new potent and selective antagonist.

Anatomical, biochemical and electrophysiological studies have previously shown that cortico-striatal terminals contain abundant presynaptic group 2 metabotropic glutamate (mGlu) receptors. Using brain slices we have previously shown that these receptors inhibit depolarization-induced transmitter release. Using microdialysis in freely moving rats, we now report the effects of group 2 mGlu receptor agonists and antagonists on glutamate concentration in the caudate extracellular fluid.

Pharmacological characterization of 1-aminoindan-1,5-dicarboxylic acid, a potent mGluR1 antagonist.

We examined the pharmacological profile of 1-aminoindan-1,5-dicarboxylic acid (AIDA), a rigid (carboxyphenyl)glycine derivative acting on metabotropic glutamate receptors (mGluRs). In cells transfected with mGluR1a, AIDA competitively antagonized the stimulatory responses of glutamate and (1S,3R)-1-aminocyclopentane-1,3-dicarboxylic acid [(1S,3R)-ACPD] on phosphoinositide hydrolysis (pA2 = 4.21).
