Factors associated with stigma in patients undergoing hemodialysis: a meta-analysis and systematic review.

Background: Patients with hemodialysis (HD) frequently encounter stigma, which impacts their social network and adherence to treatment, increasing their risk of depression and lowering their quality of life. The factors associated with stigma among patients with HD remain poorly understood due to insufficient evidence. To fill this gap, this meta-analysis was conducted.

Effect of Internet Use on Cognitive Function of Middle-Aged and Elderly Adults in China: Evidence from China Family Panel Studies.

Background: The development and popularization of the Internet provides an important opportunity to advance national strategies for healthy aging, particularly the impact of the Internet on cognitive function in middle-aged and older adults.

Objective: This study aimed to quantify the impact of Internet use on the cognitive health of middle-aged and older adults (aged≥45 years).

Methods: We used data from the Chinese Family Panel Study (CFPS) survey, tested the robustness of the baseline findings by variable substitution and instrumental variables methods, and analyzed heterogeneity.

Nitrated T cell epitope linked vaccine targeting CD47 elicits antitumor immune responses and acts synergistically with vaccine targeting PDL1.

Despite the clinical breakthrough made by immune checkpoint blockades (ICB) in cancer immunotherapy, immunosuppressed tumor microenvironment (TME) remains a major impediment in the efficacy of ICB immunotherapy. In this study, we constructed a Nitrated T cell epitope (NitraTh) linked vaccine targeting CD47, namely CD47-NitraTh. CD47-NitraTh could repress the progression of tumor by inducing tumor-specific immune response.

PDL1-targeted vaccine exhibits potent antitumor activity by simultaneously blocking PD1/PDL1 pathway and activating PDL1-specific immune responses.

Despite the clinical success of immune checkpoint blockade, only a subset of people exhibits durable responses, suggesting that an alternative immunotherapeutic strategy is required. This paper reported a two-in-one cancer vaccine that targets programmed death ligand 1 (PDL1) that blocks the PD1/PDL1 pathway and also activates antitumor immune response. The PDL1- NitraTh vaccine, which consists of the extracellular domain of PDL1 and nitrated T cell epitope, effectively broke the immune tolerance of PDL1 and elicited PDL1-specific humoral and cellular immunity.

An immune-related gene pairs signature predicts overall survival in serous ovarian carcinoma.

Background: Ovarian cancer has the highest death rate of all fatal gynecological cancers. Increasing evidence has depicted the correlation between serous ovarian carcinoma prognosis and immune signature. Therefore, the aim of this study is to develop a robust prognostic immune-related gene pairs (IRGPs) signature for estimating overall survival (OS) of HGSOC.

An immune-related gene signature predicts prognosis of gastric cancer.

Background: Although the outcome of patients with gastric cancer (GC) has improved significantly with the recent implementation of annual screening programs. Reliable prognostic biomarkers are still needed due to the disease heterogeneity. Increasing pieces of evidence revealed an association between immune signature and GC prognosis.

DFT Study and Monte Carlo Simulation on the Aminolysis of XC(O)OCH3 (X = NH2, H, and CF3) with Monomeric and Dimeric Ammonias.

The aminolysis of substituted methylformates (XC(O)OCH3, X = NH2, H, and CF3) in the gas phase and acetonitrile are investigated by the density functional theory B3LYP/6-311+G(d,p) method and Monte Carlo (MC) simulation with free energy perturbation (FEP) techniques. The direct and the ammonia-assisted aminolysis processes are considered, involving the monomeric and dimeric ammonia molecules, respectively. In each case, two different pathways, the concerted and stepwise, are explored.
