RESUMEN
Citrus citrus peeling has a wide range of vitamins and trace minerals that have antioxidant and antimicrobial properties. It is hypothesized that the addition of citrus peeling to broiler quail diets can improve their production performance, humoral immunity, nutrients, and energy utilization. A trial was performed to study the impact of a methanolic extract of citrus peeling (Citrus sinensis) on production performance, humoral immunity, nutrients, and energy utilization of broiler quails. A healthy day-old 300 quails were randomly assigned with 5 replicates each replicate had 15 birds and used CRD for the trial. Different dietary supplementations were presented to different groups. The control group was not supplemented with any supplementation in their feed. While, the 3 other groups were supplemented by 0.5 mL/kg, 1 mL/kg, and 1.5 mL/kg of methanolic extract of dried Citrus sinensis peel (DCSP) in the basal diet (DCSP0.5, DCSP1, and DCSP1.5 groups, respectively). All the birds were allowed ad libitum feeding and water. The feed intake and FCR were significantly higher in the control group, followed by DCSP0.5, and then DCSP1. The significantly lowest feed intake and FCR were observed in the DCSP1.5 group. The weight gain and dressing % were significantly improved with the increasing level of methanolic extract of Citrus sinensis. The significantly highest weights of thymus, spleen, and bursa were recorded in the DCSP1.5 group, followed by the DCSP1. The antibody titers against infectious bursal disease, New Castle disease, and infectious bronchitis disease were significantly higher in the DCSP1.5, DCSP1, and DCSP0.5 groups than in the control group. It was concluded from the study that supplementation of quails with methanolic extract of citrus at a dose rate of 0.5 to 1.5 mL/kg of feed can improve feed intake, weight gain, FCR, dressing percentage, relative weight of lymphoid organs, and digestibility coefficient. Supplementation of Citrus sinensis has also concluded positive impacts on antibody titers against various viral diseases. The best improvement in the evaluated parameters was observed at a dose of extract of citrus was 1.5 mL/kg of feed.

Objective: This study aimed to evaluate the current practice of community pharmacists from patients' and pharmacists' perspectives in Saudi Arabia. This paper presents the patients' perspective. Methods: A self-administered cross-sectional survey was developed to collect responses from patients in Saudi Arabia from February to April 2021. The questionnaire comprised several statements related to the best practice in community pharmacy. Patients' responses to each statement were scored using a 5-point Likert scale. Higher scores represented the greater extent to which the pharmacists perform the best practice in a community pharmacy setting and vice versa. Findings: The data of 233 participants were included in the analysis. The majority of the participants were female (67%) and Saudi nationals (96%). The minimum mean score was related to the statement: pharmacist discusses with you about herbal medications or vitamin supplements. The maximum mean score was related to the statement: Pharmacist explains to you about the dose of medications and when to take them. Participants who were <20 years old had a significantly highest mean score, whereas those above 40 years old had the least mean score, P = 0.001. Participants from the Eastern region had a significantly highest mean score, compared to South region participants who had the least mean score, P = 0.009. Conclusion: A gap in the current practice and the best practice of community pharmacists was found. The policymakers can utilize these findings to provide targeted professional development opportunities for the practicing community pharmacists to improve the overall service and care for the patients.
RESUMEN
Elucidation of bioactive chemical compounds from rhizobacteria is highly utilized in pharmaceuticals and naturopathy, due to their health benefits to human and plants. In current study, four cyclopeptides along with one phenyl amide were isolated from the ethyl acetate extract of Bacillus velezensis sp. RA5401. Their structures were determined and characterized as cycle (L-prolyl-L-leucyl)2 (1), cyclo (L-prolyl-l-valine)2 (2), cycle (L-phenylanalyl-L-propyl)2 (3), cyclo (D-pro-L-tyr-L-pro-L-tyr)2 (4) and N-(2-phenylethyl)acetamide (5) on the basis of electron spray ionization mass spectrometry (ESI-MS), nuclear magnetic resonance (NMR) techniques and comparison with the literature data. The five compounds have been isolated for the first time from this species. The effect of various concentrations of these compounds on the proliferation of MDA-MB-231 breast cancer cells was examined. It was found that 1 and 2 induced concentration-independent anti-proliferative effects, while 3, 4 and 5 inhibited cancer cell proliferation in a concentration-dependent manner. Furthermore, to determine the suitable binding targets of these compounds within cancer cell line, detailed target prediction and comparative molecular-docking studies were performed. The compounds 1 and 2 hit intracellular anti-cancer targets of proteases family, while compounds 3, 4 and 5 interacted with different membrane receptors of G-Protein-Coupled Receptors (GPCRs). In conclusion, the Bacillus velezensis RA5401 can be an ideal strain to produce anti-proliferative constituents at industrial scale.
