在荒漠和绿洲过渡带，防风固沙是解决荒漠化和沙漠化问题的重要手段之一。骆驼刺（Alhagi sparsifolia）是沙漠地区常见的一种荒漠深根植物，对防风固沙起到重要作用。当地居民不合理的利用方式导致骆驼刺植被遭受大面积的破坏。本试验以骆驼刺为研究对象，设置自然对照（control group， CK）、春季砍伐（cutting in spring， CS）、春季火烧（burning in spring， BS）、秋季砍伐（cutting in fall， CF）和洪水灌溉（flood water irrigation， FI）5个处理，研究不同干扰方式对骆驼刺生长特征及土壤风蚀的影响。结果表明，在经历13年后（2010—2023年），自然对照（CK）的株高和冠幅显著高于其他干扰方式，洪水灌溉后的多样性指数、均匀度指数和物种丰富度显著高于其他干扰方式。在不同干扰方式下，土壤的pH、电导率、全氮、全磷、全钾和速效磷差异不显著。洪水灌溉（FI）后的土壤速效氮显著低于自然对照（CK），而土壤有机碳和速效钾显著低于春季砍伐（CS）。春季火烧（BS）后的土壤风蚀高度显著低于其他干扰方式。土壤风蚀高度与植株的株高和冠幅呈显著正相关。研究结果为更好地保护和合理利用骆驼刺及其他荒漠植被资源提供科学依据。

Background: Emergence agitation (EA) is a common phenomenon observed in pediatric patients following general anesthesia. this study aimed to assess the efficacy of propofol and fentanyl in preventing EA and to compare their associated complications or side effects. methods: this prospective randomized observational comparative study was conducted at Dhaka medical College Hospital from July 2013 to June 2014. the study aimed to evaluate the effects of propofol and fentanyl on EA in children aged 18 to 72 months undergoing circumcision, herniotomy, and polypectomy operations. Ninety children were included in the study, with 45 in each group. Patients with psychological or neurological disorders were excluded. Various parameters including age, sex, weight, American Society of Anesthesiologists (ASA) class, duration of anesthesia, Saturation of Peripheral Oxygen (SPO2), heart rate (HR), respiratory rate (RR), Pediatric Anesthesia Emergence Delirium (PAED) score, duration of post-anesthesia care unit (PACU) stay, incidence of laryngospasm, nausea, vomiting, and rescue drug requirement were compared between the two groups. Results: Age, sex, weight, ASA class, and duration of anesthesia were comparable between the two groups. Perioperative SpO2 and HR were similar in both groups. However, the PAED score was significantly higher in the fentanyl group during all follow-ups except at 30 minutes postoperatively. the mean duration of PACU stay was significantly longer in the fentanyl group. Although the incidence of laryngospasm was higher in the fentanyl group, it was not statistically significant. Conversely, nausea or vomiting was significantly higher in the fentanyl group. the requirement for rescue drugs was significantly higher in the fentanyl group compared to the propofol group. Conclusion: Both propofol and fentanyl were effective in preventing emergence agitation in pediatric patients undergoing various surgical procedures under sevoflurane anesthesia. However, propo

A 12-week feeding trial with juvenile red drum(Sciaenops ocellatus) fed high-soybean meal(SBm) diets was conducted to investigate a putative biomarker of nutritional imbalance, N-formimino-L-glutamate(FIGLU). three fishmeal-free, 60% SBm pelleted diets(named B12, Fol, and met, respectively) were tested to evaluate the effects on growth performance and tissue metabolite profiles of supplementation of vitamin B12(0.012 mg/kg), folate(10 mg/kg), methionine(1 g/kg) respectively, above basal supplementation levels. A fourth SBm-based diet(named B12/Fol/met) was formulated with a combination of B12, folate, and methionine to attain the above-mentioned target concentrations. A fifth 60% SBm diet(named FWS) with methionine supplementation(1 g/kg above basal supplementation levels), enriched with taurine, lysine and threonine as well as minerals, was also tested. this diet contained formulation targets and additives which have allowed for replacing fishmeal with plant proteins in rainbow trout feeds. Control diets included a fishmeal-based diet(named Fm), an unsupplemented basal 60% SBm diet(named SBm60), and a “natural” diet(named N) made up of equal parts of fish(cigar minnows), squid and shrimp as a positive reference for growth performance. Formulated feeds contained approximately 37% total crude protein, approximately 14% total crude lipid and were energetically balanced. Standard growth performance metrics were measured, and tissues(liver, muscle) were collected at week 12 to evaluate diet-induced metabolic changes using nuclear magnetic resonance(NmR)-based *** results show that the FWS diet outperformed all other SBm diets and the Fm diet under all performance metrics(Pt detected in fish fed the N diet but was detected in those fed the SBm diets and the Fm diet.
