Obesity is positively Associated with Depression in Older Adults: Role of Systemic Inflammation.

Objective: We aimed to explore the association between obesity and depression and the role of systemic inflammation in older adults.

Methods: Adults ≥ 65 years old ( = 1,973) were interviewed at baseline in 2018 and 1,459 were followed up in 2021. General and abdominal obesity were assessed, and serum C-reactive protein (CRP) levels were measured at baseline.

Discovery of pentacyclic triterpenoid glycosides with anti-proliferative activities from Ardisialindleyana.

One new pentacyclic triterpenoid glycoside, ardisiapunine E (1), along with two known compounds were isolated from the root of Ardisia lindleyana D.Dietr. Their structures were elucidated by H and C NMR, DEPT, HMBC, HSQC, H-H COSY and NOESY spectroscopic analyses, ESI-MS, and literature.

Sacubitril/Valsartan Decreases Atrial Fibrillation Susceptibility by Inhibiting Angiotensin II-Induced Atrial Fibrosis Through p-Smad2/3, p-JNK, and p-p38 Signaling Pathways.

Sacubitril/valsartan (SAC/VAL) prevents angiotensin II (AngII) from binding AT1-R and blocks degradation of natriuretic peptides. Despite its efficacy in reducing ventricular fibrosis and preserving cardiac functions, which has been extensively demonstrated in myocardial infarction or pressure overload models, few studies have been conducted to determine whether SAC/VAL could attenuate atrial fibrosis and decrease atrial fibrillation (AF) susceptibility. Our study provided evidence for the inhibition of atrial fibrosis and reduced susceptibility to AF by SAC/VAL.

Atrial fibrosis underlying atrial fibrillation (Review).

Atrial fibrillation (AF) is one of the most common tachyarrhythmias observed in the clinic and is characterized by structural and electrical remodelling. Atrial fibrosis, an emblem of atrial structural remodelling, is a complex multifactorial and patient‑specific process involved in the occurrence and maintenance of AF. Whilst there is already considerable knowledge regarding the association between AF and fibrosis, this process is extremely complex, involving intricate neurohumoral and cellular and molecular interactions, and it is not limited to the atrium.

Lefty1 Ameliorates Post-infarction Fibrosis by Suppressing p-Smad2 and p-ERK1/2 Signaling Pathways.

Transforming growth factor-β1 signaling pathways are known to involve in the development of post-infarction fibrosis, a process characterized by the aberrant activation, proliferation, and differentiation of fibroblasts, as well as the unbalanced turnover of extracellular matrix proteins. Recent studies have shown that Lefty1, a novel member of TGF-β superfamily, acts as a brake on the TGF-β signaling pathway in non-cardiac tissues. However, its role in myocardial infarction (MI)-induced fibrosis and left ventricular remodeling has not been fully elucidated.

Emerging Role of TRIM Family Proteins in Cardiovascular Disease.

Ubiquitination is one of the basic mechanisms of cell protein homeostasis and degradation and is accomplished by 3 enzymes, E1, E2, and E3. Tripartite motif-containing proteins (TRIMs) constitute the largest subfamily of RING E3 ligases, with >70 current members in humans and mice. These members are involved in multiple biological processes, including growth, differentiation, and apoptosis as well as disease and tumorigenesis.

A Review of the Epidemiological Evidence for Adducin Family Gene Polymorphisms and Hypertension.

Hypertension is one of the most common cardiovascular diseases that seriously endangers human health and has become a significant public health problem worldwide. In the vast majority of patients, the cause of hypertension is unknown, called essential hypertension (EH), accounting for more than 95% of total hypertension. Epidemiological and genetic studies of humans and animals provide strong evidence of a causal relationship between high salt intake and hypertension.

Numerical simulation of bypass evaporation system treating FGD wastewater using high temperature flue gas.

A novel zero-liquid discharge (ZLD) technology for desulfurization wastewater treatment is put forward in this paper. A ZLD reconstruction project performed on 2 × 320 MW desulfurization system was taken as the research object, to study the evaporator structure and the key factors affecting spray evaporation through CFD numerical simulation. The result shows that when the evaporator diameter is 2.

[A primary investigation on the isoniazid-induced alterations in efflux gene expression among the isoniazid resistant Mycobacterium tuberculosis clinical isolates].

Objective: To detect the changes on the expression of putative drug efflux genes caused by isoniazid-inducement in single resistance to the isoniazid Mycobacterium tuberculosis (M. tuberculosis) clinical isolates, for exploring the putative efflux genes which causing M. tuberculosis isoniazid resistance as well as the mechanism related to high expression of the putative efflux genes.

Potent inhibition of the CD4-dependent T cell response by J2, a novel nonpeptide organic ligand of CD4 D1.

The interaction between CD4 and major histocompatibility complex (MHC) class II proteins is critical for the activation of CD4+ T cells, which are involved in transplantation reactions and a number of autoimmune diseases. It is known that the CD4 N-terminal immunoglobulin variable region-like domain (D1) is directed toward and reaching into the two membrane-proximal domains of the MHC class II molecule. Thus, compounds targeted to D1 would be expected to function as the inhibitors of the interaction of CD4 and class II MHC molecules.
