In the summer of 2023,two US restaurants added a novel item to their menus:chicken grown in a lab(Fig.1)[1,2].The first to receive regulatory approval for commercial sale,the lab-grown—or"cultivated"—meat starts as a few real chicken cells that are grown in vats of liquid and nutrients until they become pieces large enough to shape into nuggets and strips.

Data storage solutions are a crucial aspect of any application, significantly impacting data management and system performance. This article explores the rationale behind utilizing both SQL and NoSQL databases, addressing key questions about when each type is preferable. The background emphasizes the importance of selecting the appropriate database technology to meet specific application requirements. The purpose of this research is to provide a comprehensive guide for choosing between SQL and NoSQL databases based on various factors, including workload characteristics, scalability needs, and consistency requirements. To achieve this, we examine different strategies for implementing SQL and NoSQL databases in large-scale distributed applications and systems. The research method involves a comparative analysis of the features, advantages, and limitations of both database types. We specifically focus on scenarios involving read-heavy versus write-heavy systems and the trade-offs between availability and consistency. The results of this research indicate that SQL databases, with their relational structure and ACID compliance, are ideal for applications requiring complex queries and data integrity. In contrast, NoSQL databases, offering schema flexibility and horizontal scalability, are better suited for managing extensive datasets and high-velocity data ingestion. In conclusion, the selection of a database depends on the specific needs of the application. SQL databases are preferred for transactional systems with complex relationships, while NoSQL databases excel in scenarios demanding flexibility and scalability. The study provides insights into hybrid approaches, leveraging both database types to optimize system performance.

Background Dairy cows are at high risk of fatty liver disease in early lactation,but current preventative measures are not always *** with fatty liver have lower circulating branched-chain amino acid(BCAA)concentra-tions whereas cows with high circulating BCAA levels have low liver triglyceride(TG).Our objective was to determine the impact of BCAA and their corresponding ketoacids(branched-chain ketoacids,BCKA)on production performance and liver TG accumulation in Holstein cows in the first 3 weeks *** Thirty-six multiparous Holstein cows were used in a randomized block design *** were abomasally infused for the first 21 d postpartum with solutions of 1)saline(CON,n=12);2)BCA(67 g valine,50 g leu-cine,and 34 g isoleucine,n=12);and 3)BCK(77 g 2-ketovaline calcium salt,57 g 2-ketoleucine calcium salt,and 39 g 2-ketoisoleucine calcium salt,n=12).All cows received the same *** effects were determined using PROC GLIMMIX in *** No differences were detected for body weight,body condition score,or dry matter intake averaged over the first 21 d *** receiving BCK had significantly lower liver TG concentrations compared to CON(6.60%vs.4.77%,standard error of the mean(SEM)0.49)during the first 3 weeks of *** of BCA increased milk yield(39.5 vs.35.3 kg/d,SEM 1.8),milk fat yield(2.10 vs.1.69 kg/d,SEM 0.08),and lactose yield(2.11 vs.1.67 kg/d,SEM 0.07)compared with *** to CON,cows receiving BCA had lower plasma glucose(55.0 vs.59.2 mg/dL,SEM 0.86)but higherβ-hydroxybutyrate(9.17 vs.6.00 mg/dL,SEM 0.80).Conclusions Overall,BCAA supplementation in this study improved milk production,whereas BCKA supplementa-tion reduced TG accumulation in the liver of fresh cows.

Open Journal of Endocrine and Metabolic Diseases 2024年第4期14卷 94-100页

作者： Martina Grech sarah Refalo Azzopardi Department of Ophthalmology Mater Dei University Hospital Msida Malta

Diabetic retinopathy is a leading cause of preventable vision impairment and a common complication of diabetes. Diabetic retinopathy screening can identify early changes in the retina so treatment can be given before vision impairment or blindness occurs. The aim of this audit is to evaluate the diabetic eye screening pathway in Malta to reduce the risk of vision impairment among diabetic patients through the identification and effective management of sight-threatening diabetic retinopathy by evaluating adherence to diabetic retinopathy screening guidelines and identifying areas for improvement within the screening pathway at Mater Dei Hospital (MDH). The practical implications of the audit’s findings highlight the importance of more awareness of current guidelines on the recommended time of first eye examination and routine minimum follow up interval at the Endocrinology Department at MDH. 26.7% of the doctors participating in this audit perform fundoscopy on initial assessment only, while 13.3% perform fundoscopy every visit. On the other hand, 60% of the participants never perform fundoscopy.
