Background: Liraglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist that prevents metabolic side effects of the antipsychotic drugs (APDs) olanzapine and clozapine through unknown mechanisms. Aim: This study aimed to investigate the effect of chronic APD and liraglutide co-treatment on key neural and peripheral metabolic signals, and acute liraglutide co-treatment on clozapine-induced hyperglycaemia. Methods: In study 1, rats were administered olanzapine (2 mg/kg), clozapine (12 mg/kg), liraglutide (0.2 mg/kg), olanzapine + liraglutide co-treatment, clozapine + liraglutide co-treatment or vehicle for six weeks. Feeding efficiency was examined weekly. Examination of brain tissue (dorsal vagal complex (DVC) and mediobasal hypothalamus (MBH)), plasma metabolic hormones and peripheral (liver and kidney) cellular metabolism and oxidative stress was conducted. In study 2, rats were administered a single dose of clozapine (12 mg/kg), liraglutide (0.4 mg/kg), clozapine + liraglutide co-treatment or vehicle. Glucose tolerance and plasma hormone levels were assessed. Results: Liraglutide co-treatment prevented the time-dependent increase in feeding efficiency caused by olanzapine, which plateaued by six weeks. There was no effect of chronic treatment on melanocortinergic, GABAergic, glutamatergic or endocannabionoid markers in the MBH or DVC. Peripheral hormones and cellular metabolic markers were unaltered by chronic APD treatment. Acute liraglutide co-treatment was unable to prevent clozapine-induced hyperglycaemia, but it did alter catecholamine levels. Conclusion: The unexpected lack of change to central and peripheral markers following chronic treatment, despite the presence of weight gain, may reflect adaptive mechanisms. Further studies examining alterations across different time points are required to continue to elucidate the mechanisms underlying the benefits of liraglutide on APD-induced metabolic side effects.

Body weight and seven body dimensions measuring the length, height, width and depth were taken at birth and every 180 days up to 720 days of age on 49 pure Canadian, 49 first cross of 1/2 Brown Swiss 1/2 Canadian, and 30 backcross of 1/4 Brown Swiss 3/4 Canadian heifers. The animals were raised up to 180 days of age at the Deschambault Station, then half the pure Canadian and the first cross were transferred to the La Pocatière Station. At birth, the pure Canadian calves weighed 29.2 kg and were lighter than the first and backcrosses by 6.9 kg (24%) and 4.8 kg (16%), respectively. The two crosses exceeded the pure Canadian in all the dimensions, the differences being significant in height at shoulder and width at rumps. At 360 days of age the two crosses were about 6% heavier and 4% higher at shoulder than the pure Canadian. With the exception of body length after 1 yr of age in which the backcross was slightly inferior to the pure Canadian, the two crosses were generally larger than the pure Canadian, with the backcross being intermediate between the first cross and the pure Canadian. The effects of season of birth and age of dam were found to be non-significant on most of the traits studied in this experiment.

Objective This review article aimed to explore the effect of oral motor intervention on oral feeding in preterm infants through a meta-analysis. Method Eligible studies were retrieved from four databases (PubMed, Embase, Cochrane Library, and Web of Science) up to July 2020 and screened based on established selection criteria. Thereafter, relevant data were extracted and heterogeneity tests were conducted to select appropriate effect models according to the chi-square test and I 2 statistics. Assessment of risk of bias was performed among the included studies. Finally, a meta-analysis was carried out to evaluate the effect of oral motor intervention in preterm infants according to four clinical indicators: transition time for oral feeding, length of hospital stay, feeding efficiency, and weight gain. Results Eighteen randomized controlled trials with 848 participants were selected to evaluate the effect of oral motor intervention on preterm infants. The meta-analysis results revealed that oral motor intervention could effectively reduce the transition time to full oral feeds and the length of hospital stay as well as increase feeding efficiency and weight gain. Conclusions Oral motor intervention was an effective way to improve oral feeding in preterm infants. It is worthy to be used widely in hospitals to improve the clinical outcomes of preterm infants and reduce the economic burdens of families and society. Future studies should seek to identify detailed intervention processes and intervention durations for clinical application.

This paper evaluates the nutritional impact on growth, production and quality variables of gerbera crop when fertigated with treated domestic effluents. An experiment was carried out in greenhouse at the Embrapa Meio-Norte in Teresina, in the State of Piauí, Brazil, from July to October 2007. A completely randomized experimental design with five treatments and five replications was adopted. The treatments investigated were T1 - 100% of water and nutritional requirements of crop were met with chemical fertigation (N e K2 O); T2 - 25% volume of water through fertigation and 75% treated wastewater effluents (TWE); T3: 50% volume of water through fertigation and 50% TWE; T4: 75% volume of water with fertigation and 25% TWE; and T5 - 100% volume of water supplied through TWE. Leaf growth and plant development were favored by the application of 50% fertigation and 50% TWE (T3). As for commercial requirements, the best results for number of flowers were obtained with T4. However, concerning quality, T2 produced flowers in July and August with longer stems, but in the months of September and October, no treatment achieved this standard due to high temperature and low relative humidity of the air in the region.
