Decoding the Multiple Identities and Crosstalk of Organokines in Obesity-Related Type 2 Diabetes Mellitus.

Obesity causes an imbalance in the expression and secretion of several organokines, which in turn contributes to the development of metabolic disorders such as type 2 diabetes mellitus. Organokines are produced by corresponding organs and affect systemic metabolic homeostasis. Diverse organokines play a crucial role in the communication between adipose tissue, skeletal muscle and other organs.

Exploring the Frontier: Antisense Long Non-Coding RNAs as Key Regulators in Alzheimer's Disease.

Alzheimer's Disease (AD) is the most prevalent, costly, and fatal neurodegenerative disorder of this century. Two hallmark features of AD are the anomalous cleavage of amyloid precursor protein (APP), which leads to the accumulation of amyloid-beta (Aβ), and the hyperphosphorylation of tau protein. Despite extensive research efforts, the pathology and pathogenesis of AD remain elusive.

Icariin attenuates the calcification of vascular smooth muscle cells through ERα - p38MAPK pathway.

Objective: To investigate the relationship between icariin and the osteoblastic differentiation of vascular smooth muscle cells (VSMCs) and the signal pathway involved.

Methods: We applied a universally accepted calcification model of VSMCs induced by β glycerophosphate. Then the VSMCs calcification was observed by treatment with icariin and/or inhibitors of estrogen receptors (ERs) and p38-mitogen-activated protein kinase (MAPK) signaling.

Sensor Scheduling for Remote State Estimation with Limited Communication Resources: A Time- and Event-Triggered Hybrid Approach.

This paper proposes a time- and event-triggered hybrid scheduling for remote state estimation with limited communication resources. A smart sensor observes a physical process and decides whether to send the local state estimate to a remote estimator via a wireless communication channel; the estimator computes the state estimate of the process according to the received data packets and the known scheduling mechanism. Based on the existing optimal time-triggered scheduling, we employ a stochastic event trigger to save precious communication chances and further improve the estimation performance.

Base-Mediated α--Difluoroalkenylations of Aldehydes and Ketones.

Herein, we present a base-mediated nucleophilic substitution reaction of α-trifluoromethylstyrenes with simple silyl enol ethers, enabling the efficient synthesis of carbonyl-substituted -difluoroalkenes.

Notably, this method demonstrates its applicability for late-stage functionalization of structurally complex molecules.

BMF-AS1/BMF Promotes Diabetic Vascular Calcification and Aging both and .

Vascular calcification and aging often increase morbidity and mortality in patients with diabetes mellitus (DM); however, the underlying mechanisms are still unknown. In the present study, we found that Bcl-2 modifying factor (BMF) and BMF antisense RNA 1 (BMF-AS1) were significantly increased in high glucose-induced calcified and senescent vascular smooth muscle cells (VSMCs) as well as artery tissues from diabetic mice. Inhibition of BMF-AS1 and BMF reduced the calcification and senescence of VSMCs, whereas overexpression of BMF-AS1 and BMF generates the opposite results.

Association between the Triglyceride-Glucose Index and Vitamin D Status in Type 2 Diabetes Mellitus.

Background: Vitamin D deficiency (VDD) increases the risk for type 2 diabetes mellitus (T2DM), which might be related to insulin resistance (IR). We aimed to explore the association between the triglyceride-glucose (TyG) index, a reliable indicator of IR, and VDD in patients with T2DM.

Methods: There were 1034 participants with T2DM enrolled in the Second Xiangya Hospital of Central South University.

Long noncoding RNA SNHG1 alleviates high glucose-induced vascular smooth muscle cells calcification/senescence by post-transcriptionally regulating Bhlhe40 and autophagy via Atg10.

Long noncoding RNAs (lncRNAs) are emerging regulators of vascular diseases, yet their role in diabetic vascular calcification/aging remains poorly understood. In this study, we identified a down-expressed lncRNA SNHG1 in high glucose (HG)-induced vascular smooth muscle cells (HA-VSMCs), which induced excessive autophagy and promoted HA-VSMCs calcification/senescence. Overexpression of SNHG1 alleviated HG-induced HA-VSMCs calcification/senescence.

Thermal Hazard Evaluation of Tert-Butyl Peroxy-3,5,5-trimethylhexanoate (TBPTMH) Mixed with Acid-Alkali.

Tert-butyl peroxy-3,5,5-trimethylhexanoate (TBPTMH), a liquid ester organic peroxide, is commonly used as an initiator for polymerization reactions. During the production process, TBPTMH may be exposed to acids and alkali, which may have different effects on its thermal hazard, so it is necessary to carry out a study on the thermal hazard of TBPTMH mixed with acids and alkali. In this paper, the effects of HSO and NaOH on the thermal decomposition of TBPTMH were investigated by differential scanning calorimetry (DSC) and adiabatic calorimetry (Phi-TEC II).

Roles of Long Non-coding RNAs in the Development of Aging-Related Neurodegenerative Diseases.

Aging-related neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS), are gradually becoming the primary burden of society and cause significant health-care concerns. Aging is a critical independent risk factor for neurodegenerative diseases. The pathological alterations of neurodegenerative diseases are tightly associated with mitochondrial dysfunction, inflammation, and oxidative stress, which in turn stimulates the further progression of neurodegenerative diseases.

Experimental Study of the Thermal Decomposition Properties of Binary Imidazole Ionic Liquid Mixtures.

Ionic liquids (ILs) have a wide range of applications, owing to their negligible vapor pressure, high electrical conductivity, and low melting point. However, the thermal hazards of ILs and their mixtures are also non-negligible. In this study, the thermal hazards of various binary imidazolium ionic liquids (BIIL) mixtures were investigated.

Roles and mechanisms of exosomal non-coding RNAs in human health and diseases.

Exosomes play a role as mediators of cell-to-cell communication, thus exhibiting pleiotropic activities to homeostasis regulation. Exosomal non-coding RNAs (ncRNAs), mainly microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), are closely related to a variety of biological and functional aspects of human health. When the exosomal ncRNAs undergo tissue-specific changes due to diverse internal or external disorders, they can cause tissue dysfunction, aging, and diseases.

Vascular aging is defined as organic and functional changes in blood vessels, in which decline in autophagy levels, DNA damage, MicroRNA (miRNA), oxidative stress, sirtuin, and apoptosis signal-regulated kinase 1 (ASK1) are integral thereto. With regard to vascular morphology, the increase in arterial stiffness, atherosclerosis, vascular calcification and high amyloid beta levels are closely related to vascular aging. Further closely related thereto, at the cellular level, is the aging of vascular endothelial cells (ECs) and vascular smooth muscle cells (VSMCs).

Management and Outcome of Ventricular Septal Rupture Complicating Acute Myocardial Infarction: What Is New in the Era of Percutaneous Intervention?

Background: Postinfarction ventricular septal rupture (PI-VSR) is a rare but devastating complication of acute myocardial infarction (AMI). Risk stratification in the acute phase is crucial for decision-making, and this study analyzed the risk factors for early mortality and the effects of various management options on the outcome of PI-VSR patients in the era of percutaneous intervention.

Methods: A total of 96 patients with PI-VSR were identified and divided into an acute-phase survivor group (n = 46, survived ≥2 weeks after admission) and a nonsurvivor group (n = 50, died within 2 weeks after admission).
