Effects of Ethylene Propylene Diene Monomer (EPDM)-Based Polar Macromolecular Compatibilizers on the Low-Temperature Properties of Fluoroelastomer/EPDM Rubber Blends.

Integrating rubber with superior low-temperature capabilities, such as ethylene propylene diene monomer (EPDM), is a strategic approach to bolster the low-temperature performance of fluoroelastomer (FKM). However, FKM and EPDM are thermodynamically incompatible. This work synthetized three EPDM-based polar macromolecular compatibilizers, epoxidized EPDM (EPDM-EP), 2,2-trifluoroethylamine-grafted epoxidized EPDM (EPDM-TF), and 2,4-difluorobenzylamine-grafted epoxidized EPDM (EPDM-DF), to enhance the compatibility between FKM and EPDM.

Postpartum life interventions to prevent type 2 diabetes in women with gestational diabetes: A systematic review and meta-analysis.

Aims/introduction: Type 2 diabetes mellitus is a major metabolic disease that seriously endangers life and health, but women with gestational diabetes mellitus are at increased risk for developing type 2 diabetes mellitus. This study aimed to evaluate the effectiveness of postpartum lifestyle intervention on the prevention of type 2 diabetes mellitus, and the effect of lifestyle intervention on glycemic outcomes and anthropometric measures.

Materials And Methods: We searched PubMed and other databases to retrieve articles published before May 21, 2023, on randomized controlled trials of postnatal lifestyle interventions (diet and/or physical activity) in women with gestational diabetes mellitus.

Genome-Wide DNA Methylation Pattern in Whole Blood Associated With Primary Intracerebral Hemorrhage.

Primary intracerebral hemorrhage (ICH) is a significant cause of morbidity and mortality throughout the world. ICH is a multifactorial disease that emerges from interactions among multiple genetic and environmental factors. DNA methylation plays an important role in the etiology of complex traits and diseases.

Assessing different interventions against Avian Influenza A (H7N9) infection by an epidemiological model.

This paper aims at evaluating the effectiveness of different intervention measures against the infection of avian influenza A (H7N9) by using an epidemiological model. The model formulates the intrinsic interactions of domestic poultry (DP), H7N9 virus and humans by ordinary differential equations and couples the essential roles of various interventions (including culling, vaccinating, screening, disinfecting, and reducing contact rate, etc). Qualitative analysis indicates that when the recruiting poultry is virus-free, there is a transmission threshold denoted by basic reproduction number which can determine the invasion of H7N9; and there is always a stable H7N9 endemic in case of persistent import of virus-carrying poultry, under which only complete vaccination or cutting off poultry-to-poultry/human contacts can stop H7N9 transmission.

The impact of the COVID-19 pandemic on socio-economic and sustainability.

The COVID-19 pandemic has adversely affected the lives of people around the world in millions of ways . Due to this severe epidemic, all countries in the world have been affected by all aspects, mainly economic. It is widely discussed that the COVID-19 outbreak has affected the world economy.

Different intervention strategies toward live poultry markets against avian influenza A (H7N9) virus: Model-based assessment.

Background: Different interventions targeting live poultry markets (LPMs) are applied in China for controlling avian influenza A (H7N9), including LPM closure and "1110" policy (i.e., daily cleaning, weekly disinfection, monthly rest day, zero poultry stock overnight).

DNA methylation in Alzheimer's disease: In brain and peripheral blood.

Alzheimer's disease (AD) is the most widespread neurodegenerative disorder and has caused a major global health concern with the aging of the population. Recent studies have suggested a role for epigenetic mechanisms in AD. DNA methylation is a vital component of the epigenetic machinery which is the best-studied example covered by epigenetics.

Clinical characteristic and intraoperative findings of uterine perforation patients in using of intrauterine devices (IUDs).

Background: Intrauterine devices (IUDs) are the most popular form of contraception used worldwide; however, IUD is not risk-free. IUD migrations, especially uterine perforations, were frequently occurred in patients. The aim of this study was to investigate the clinical characteristics and intraoperative findings in patients with migrated IUDs.

The Effect of Comprehensive Care on the Patients Received Minimally Invasive Percutaneous Nephrolithotomy.

Background: We analyzed the effect of comprehensive care on the patients who received minimally invasive percutaneous nephrolithotomy (MPCNL).

Methods: Patients hospitalized from 2013-2014 in Zhumadian Central Hospital (n=124) were enrolled and divided into two groups on random basis. The control group was treated with routine nursing model while the observation group was given comprehensive care additionally.

Vitamin D Deficiency and Increased Risk of Bladder Carcinoma: A Meta-Analysis.

Background/aims: Vitamin D status in relation to bladder carcinoma risk was still inconsistent. This study was carried out to evaluate the relationship between vitamin D status and bladder carcinoma risk through a meta-analysis approach.

Methods: Pubmed, Web of Science, CNKI, and Embase were searched systemically to find eligible studies from the earliest available date to April 16, 2015.

[Changes in T-cell receptor repertoire in aplastic anemia and effects of Shengxue Mixture].

Objective: To explore the immune pathogenesis of aplastic anemia (AA) and the therapeutic effects of Shengxue Mixture (SM) through the gene expressions of subfamilies of T-cell receptor variable region beta (TCR Vbeta) using immunologic and molecular biologic technology.

Methods: Gene expressions of TCR Vbeta sub-families in peripheral blood mononuclear cells from 20 AA patients were detected before and after treatment with SM using RT-PCR and gene scanning method.

Results: TCR Vbeta gene repertoire of the 24 subfamily genes deviated in AA patients, and the oligoclonal gene expressions increased obviously compared with those in healthy people (P < 0.
