In this study, we investigated the performance improvement caused by the addition of copper(Cu)nanoparticles to high-density polyethylene(HDPE) matrix material. Composite materials, with filler percentages of 0.0, 2.0, 4.0, 6.0, 8.0, and 10.0 wt% were synthesized through the material extrusion(MEX)3D printing technique. The synthesized nanocomposite filaments were utilized for the manufacturing of specimens suitable for the experimental procedure that followed. Hence, we were able to systematically investigate their tensile, flexural, impact, and microhardness properties through various mechanical tests that were conducted according to the corresponding standards. Broadband Dielectric Spectroscopy was used to investigate the electrical/dielectric properties of the composites. Moreover, by employing means of Raman spectroscopy and thermogravimetric analysis(TGA) we were also able to further investigate their vibrational, structural, and thermal properties. Concomitantly, means of scanning electron microscopy(SEM), as well as atomic force microscopy(AFM), were used for the examination of the morphological and structural characteristics of the synthesized specimens, while energy-dispersive Xray spectroscopy(EDS) was also performed in order to receive a more detailed picture on the structural characteristics of the various synthesized composites. The corresponding nanomaterials were also assessed for their antibacterial properties regarding Staphylococcus aureus(S. aureus) and Escherichia coli(E. coli) with the assistance of a method named screening agar well diffusion. The results showed that the mechanical properties of HDPE benefited from the utilization of Cu as a filler, as they showed a notable improvement. The specimen of HDPE/Cu 4.0 wt% was the one that presented the highest levels of reinforcement in four out of the seven tested mechanical properties(for example, it exhibited a 36.7%improvement in the flexural strength, compared to the pure matrix).

保健品中添加营养素并不新鲜，但是在去除肉鸡饲料中有用药物产品时，这些营养素的组合有新的应用。从肉鸡饲料中除去抗细菌和抗原生动物的抗生素则会增加肠道健康问题的发生率。坏死性肠炎是一种由不受控制梭状芽胞杆菌菌群产生毒素引起的多因素疾病，该病在大多数肉鸡厂已经成为常见困扰。对于不使用预防剂，即离子载体与其他抗生素一同禁用的鸡场来说，球虫病的发生也极其普遍。

The development of type 2 diabetes mellitus is a major contributing factor to the worldwide health burden of metabolic dysfunction-associated steatotic liver disease(MASLD).Insulin resistance,subclinical inflammation,dyslipidemia,obesity,and hypertension are all factors in this reciprocal interaction that contribute to the development of MASLD,which includes hepatocellular carci-noma,advanced fibrosis/cirrhosis,and non-alcoholic steatohepatitis(NASH).A new risk factor for MASLD/NASH that affects the course of the disease independently throughout life is gestational diabetes mellitus(GDM).Women with a history of GDM had a higher chance of developing NASH,according to a recent study that used a large-scale *** the precise etiology is yet unknown,temporary disruption of pancreatic beta cell activity during pregnancy may set off systemic inflammation,affecting distant organs including the *** screening and management strategies are crucial in mitigating MASLD progression and preventing adverse cardiovascular events in affected individuals.

In this Editorial,we highlight the possible role that metabolism dysfunction-associated steatotic liver disease(MASLD)may play in the future,regarding liver disease in patients with transfusion-dependent β-thalassemia(TDBT).MASLD is characterized by excessive accumulation of fat in the liver(hepatic steatosis),in the presence of cardiometabolic *** is a strong correlation between the occurrence of MASLD and insulin resistance,while its increased prevalence parallels the global epidemic of diabetes mellitus(DM)and *** with TDBT need regular transfusions for life to ensure their *** these transfusions,a large amount of iron is accumulated,which causes saturation of transferrin and leads to the circulation of free iron molecules,which cause damage to vital organs(primarily the liver and myocardium).Over the past,the main mechanisms for the development of liver disease in these patients have been the toxic effect of iron on the liver and chronic hepatitis C,for which modern and effective treatments have been found,resulting in successful *** advances in the treatment and monitoring of these patients have led to a reduction in deaths,and an increase in their life *** increased survival makes them vulnerable to the onset of diseases,which until recently were mainly related to the non-thalassemic general population,such as obesity and *** is insufficient data in the literature regarding the prevalence of MASLD in this population or on the risk factors for its ***,it was recently shown by a study of 45 heavily transfused patients with beta-thalassemia(Padeniya et al,BJH),that the presence of steatosis is a factor influencing the value of liver elastography and thus liver *** findings suggest that future research in the field of liver disease in patients with TDBT should be focused on the occurrence,the risk factors,and the effect of MASLD on these patients.
