The role of miRNA-144-3p/Oprk1/KOR in nicotine dependence and nicotine withdrawal in male rats.

The kappa-opioid receptor (KOR) has been implicated in mediating the behavioral and biochemical effects associated with nicotine reward and withdrawal; however, its underlying mechanisms remain to be further explored. Adult male Sprague-Dawley rats were used to establish a nicotine dependence and withdrawal model by injecting nicotine (3 mg/kg/day, s.c.) or vehicle for 14 days, followed by the termination of nicotine for 7 days. Body weight gain, pain behaviors, and withdrawal scores were assessed in succession. MicroRNA (miRNA) sequencing was performed, and quantitative real-time PCR was used to detect the expression of candidate miRNAs and Oprk1. Western blotting was performed to examine KOR protein expression of KOR. Luciferase assay was conducted to validate the relationship of certain miRNAs/Oprk1. The behavioral results showed that nicotine dependence and withdrawal induced behavioral changes. Biochemical analyses demonstrated that miR-144-3p expression decreased and Oprk1/KOR expression increased in the prefrontal cortex, nucleus accumben, and hippocampus. Further investigation suggested that miR-144-3p exerted an inhibitory effect on Oprk1 expression in PC12 cells. This study revealed that miR-144-3p/Oprk1/KOR might be a potential pathway underlying the adverse effects induced by nicotine dependence and withdrawal, and might provide a novel therapeutic target for smoking cessation. This study demonstrates an impact of nicotine dependence and nicotine withdrawal on behavioral outcomes and the expressions of miR-144-3p/Oprk1/KOR in male rats. These findings have important translational implications given the continued use of nicotine and the difficulty in smoking cessation worldwide, which can be applied to alleviated the adverse effects induced by nicotine dependence and withdrawal, thus assist smokers to quit smoking.

Undergraduate ultrasound training: prospective comparison of two different peer assisted course models on national standards

BackgroundA thorough knowledge of sonography is essential in clinical practice. Therefore, sonography training is increasingly incorporated into the medical school curriculum, entailing different course models. The question arises which model is most effective to convey sustained sonographic skills.MethodsTwo different peer-assisted learning (PAL) sonography course models were developed as part of a clinical prospective study. The course content was based on the national resident curriculum of the German Society for Ultrasound in Medicine (DEGUM). Model A consists of a 10-week course and model B of a two-day compact course. Each model entailed 20 teaching units (TU). A script was used to prepare for each unit. Two modified OSCE exams of the ultrasound skills (max = 50 points per exam) were performed during the last teaching unit to assess the competence level. For subjective self-assessment and model evaluation, a questionnaire with a 7-point Likert scale was employed.ResultsA total of 888 students of the 3rd year participated as part of a voluntary elective in the study (744 in model A and 144 in model B). In the exams, participants in model A (median 43 points) scored significantly higher than those in model B (median 39; p < 0.01). Participants in model A (mean 1.71 points) obtained significantly higher mean competency gain scores in subject knowledge than model B (mean 1.43 points; p < 0.01) participants. All participants were satisfied with the course concept (A: mean 1.68 vs. B: mean 1.78 points; p = 0.05), the teaching materials (A: mean 1.81 vs. B: mean 1.69 points; p = 0.52), and the tutor’s didactic skills (A: mean 1.24 vs. B: mean 1.15 points; p < 0.05).ConclusionThese results suggest that sonography-specific competency may be obtained through different course models, with a model stretching over several weeks leading to a higher competence level. Further research should assess the long-term retention of the skills obtained in different models.

Standard RUTF vs. locally-made RUSF for acutely malnourished children: A quasi-experimental comparison of the impact on growth and compliance in a rural community of Pakistan.

The reduction in severe and moderate acute malnutrition (SAM and MAM) rates in Pakistan has been sub-optimal compared to other low-and middle-income countries (LMICs). Specially-formulated products have been designed globally to manage SAM and MAM, such as ready-to-use therapeutic food (RUTF) and ready-to-use supplementary food (RUSF), with variable efficacies. RUTF is primarily produced and patented in industrialized countries, raising supply challenges in resource-constrained regions with a high burden of acute malnutrition. RUSF minimizes costs by using locally-available ingredients while providing similar nutritional value. In this study, we compared the efficacy, side effects, and compliance of two months of supplementation with either RUTF or RUSF. Children aged nine months in the rural district of Matiari, Pakistan, with a weight-for-height z-score (WHZ) <-2 received either RUTF (500 kcal sachet) for two months in 2015 or RUSF (520 kcal sachet) for two months in 2018. The RUSF group had a higher height gain and mid-upper arm circumferences (MUAC) score. Higher compliance was noted with lower side effects in the RUSF group. A higher compliance rate did correlate with the growth parameters in respective groups. Our study found that both RUTF and RUSF partially improve the anthropometric status of acutely malnourished children, with neither being superior to the other.

Unleashing the Potential of Social Media: Enhancing Intercultural Communication Skills in the Hospitality and Tourism Context

Intercultural communication skills play a vital role in achieving success in the global hospitality and tourism profession.

Effect of an Enteroprotective Complementary Feed on Faecal Markers of Inflammation and Intestinal Microbiota Composition in Weaning Puppies.

Weaning entails numerous modifications of the intestinal structure and microbiota composition, making puppies at high risk of sickness during this delicate life stage. The aim of this study was to investigate the effects of a four-week administration of a supplement composed of ultramicronised Palmitoylethanolamide, bovine colostrum and Bacillus subtilis (Normalia® Extra, Innovet Italia Srl, Saccolongo, Italy) on markers of gut health and microbiome of weaning puppies. Twenty-nine four-week-old Golden Retriever puppies were randomly assigned to control (CG, n = 13) and treated (TG, n = 16) groups. During the whole experimental time, there were no differences between the groups with regard to average daily gain and faecal score. In TG, faecal calprotectin and zonulin values were statistically significantly decreased compared to CG, especially at week 8 (zonulin: 42.8 ± 1.54 ng/mL and 55.3 ± 42.8 ng/mL, and calprotectin: 2.91 ± 0.38 µg/g and 5.71 ± 0.43 µg/g, in TG and CG, respectively; p < 0.0001 for both comparisons). Bacteria belonging to phylum Campylobacterota decreased (p = 0.04), while those referring to genera Coprococcus and Pseudomonas increased (p = 0.01 and p = 0.04, respectively). The supplementation of the tested complementary feed can promote the intestinal health of puppies and therefore facilitate weaning by lowering gut inflammation.
