Aging is a multidimensional process that leads to an increased risk of developing severe diseases, such as cancer and cardiovascular, neurodegenerative, and immunological diseases. Recently, small non-coding RNAs known as microRNAs （miRNAs） have been shown to regulate gene expression, which contributes to many physiological and pathophysiological processes in humans. Increasing evidence suggests that changes in miRNA expression profiles contribute to cellular senescence, aging and aging-related diseases. However, only a few miRNAs whose functions have been elucidated have been associated with aging and/or aging-related diseases. This article reviews the currently available findings regarding the roles of aging-related miRNAs, with a focus on cardiac and cardiovascular aging.

Non-alcoholic fatty liver disease affects approximately one-third of the population worldwide, and its incidence continues to increase with the increasing prevalence of other metabolic disorders such as type 2 diabetes. As non-alcoholic fatty liver disease can progress to liver cirrhosis, its treatment is attracting greater attention. The pathogenesis of non-alcoholic fatty liver disease is closely associated with insulin resistance and dyslipidemia, especially hypertriglyceridemia. Increased serum levels of free fatty acid and glucose can cause oxidative stress in the liver and peripheral tissue, leading to ectopic fat accumulation, especially in the liver. In this review, we summarize the mechanism underlying the progression of hepatic steatosis to steatohepatitis and cirrhosis. We also discuss established drugs that are already being used to treat non-alcoholic fatty liver disease, in addition to newly discovered agents, with respect to their mechanisms of drug action, focusing mainly on hepatic insulin resistance. As well, we review clinical data that demonstrate the efficacy of these drugs, together with improvements in biochemical or histological parameters.

This study tried to establish optimal conditions for Sargassum horneri extracts loaded nanostructured lipid carriers(SHE-NLCs).Therefore,we observed various physicochemical analyzes,sugar and phenolic contents,and anti-oxidants while storing the SHE-NLCs for 28 days at different SHE addition amounts(0%-0.5%)and storage temperatures(25 and 65℃).All SHE-NLCs stored at 25℃ showed a small hydrodynamic diameter(20.1-25.4 nm)and high encapsulation efficiency(64.1%-89.3%)for 28 *** the amount of SHE increased,the pH and electrical conductivity of SHE-NLCs significantly decreased and increased,respectively(p<0.05).Also,at 25℃,prevented a sharp decrease in the total phenolic content and antioxidant activity of SHE-NLCs as the storage period increased compared to 65℃.SHE 0.25%loaded NLCs can stably maintain the formulation structure for 28 days at room temperature while being an amount sufficiently containing the functionality of SHE.

Management of febrile infants,especially those younger than 3 months of age,is of clinical importance due to the relatively high risk of serious bacterial infection(SBI),such as bacterial meningitis,bacteremia,or urinary tract infection(UTI)[1].Fortunately,reliable guidelines for assessing the risk of SB I in febrile infants have been developed to help determine whether an infant should be hospitalized,undergo lumbar puncture,or be treated with antibiotics[2].However,many hospitals do not have written institutional guidelines,so clinicians often make decisions based on their own experience and knowledge[3-5].For a consistent approach to febrile infants,our hospital plans to introduce written *** this study,we estimated the expected effects of these guidelines and compared our data with the results of previous domestic studies.

The electronic structures and magnetic properties of strained monolayer MnPSe3 are investigated sys- tematically via first-principles calculations. It is found that the magnetic ground state of monolayer MnPSe3 can be significantly affected by biaxial strain engineering, while the semiconducting char- acteristics are well-preserved. Owing to the sensitivity of the magnetic coupling towards structural deformation, a biaxial tensile strain of approximately 13% can lead to an antiferromagnetic （AFM）- ferromagnetic （FM） transition. The strain-dependent magnetic stability is mainly attributed to the competition of the direct AFM interaction and indirect FM superexchange interaction between the two nearest-neighbor Mn atoms. In addition, we find that FM MnPSe3 is an intrinsic half semiconductor with large spin exchange splitting in the conduction bands, which is crucial for the spin-polarized carrier injection and detection. The sensitive interdependence among the external stimuli, electronic structure, and magnetic coupling makes monolayer MnPSe3 a promising candidate for spintronics.
