Synthesis, Characterization, and Fabrication of Nickel Metal-Organic Framework-Incorporated Polymer Electrolyte Membranes for Fuel-Cell Applications.

Proton-conducting sulfonated polymer metal-organic framework (MOF)-based composite membranes were synthesized by anchoring the nickel MOF (Ni-MOF) to the aromatic sulfonated polymer backbone. In this work, we sulfonated two different polymers, poly(1,4-phenylene ether ether sulfone) (PEES) and poly ether ether ketone (PEEK), with a controllable sulfonation degree, and the synthesized Ni-MOF was incorporated into the sulfonated polymers to prepare a polymer electrolyte membrane. The effect of an MOF as a pendant moiety on the polymer backbone had a significant effect on properties such as water uptake, thermal, mechanical, and oxidative stabilities, swelling ratio, ion-exchange capacity (IEC), morphology, proton conductivity, and fuel-cell performance.

Association of pentraxin in periodontitis patients with coronary artery disease.

Effects of nanoadditives on the performance and emissions of rapeseed biodiesel in an insulated piston diesel engine.

Energy consumption and management have emerged as crucial production functions because of the high cost of energy. Since the total consumption of fossil fuels like diesel has increased proportionally to the expansion in demand for power generation, industry, and transportation services, researchers have long been interested in constructing a more energy-efficient engine. With its improved efficiency, reduced fuel consumption, and fewer emissions, the application of nano-coating technology to engine components has become more popular in recent years.

Hyperhomocysteinemia as a Cause of Acute Ischemic Stroke in a Four-Year-Old Child: A Report of a Rare Case.

Homocysteine is a type of amino acid that isn't genetically encoded by the human body. This amino acid is capable of causing oxidative damage to the endothelial cells, leading to the onset of thrombosis. Moreover, it can also inflict harm to neurons by activating pro-apoptotic factors, causing DNA damage, and inducing oxidative stress, as observed in various animal models and cell cultures.

Evidence linking the association of periodontal viruses and pentraxins in periodontitis patients with coronary artery disease.

Background: Although there is ample evidence in the literature supporting a significant positive association between key periodontal pathogens and established inflammatory markers of periodontitis and coronary artery disease (CAD), their exact role remain unclear. Especially, the role of viruses in the etiology and specific biomarkers have not been validated. Thus, the current study aims to evaluate the role of periodontal viruses such as Epstein-Barr virus (EBV), cytomegalovirus (CMV), and herpes simplex virus (HSV), as well as the inflammatory marker pentraxin-3 (PTX3), and to analyze their association with CAD.

Inhibition of serotonin biosynthesis in neuroendocrine neoplasm suppresses tumor growth .

Small bowel neuroendocrine tumors (SBNETs) originate from enterochromaffin cells in the intestine which synthesize and secrete serotonin. SBNETs express high levels of tryptophan hydroxylase 1 (Tph1), a key enzyme in serotonin biosynthesis. Patients with high serotonin level may develop carcinoid syndrome, which can be treated with somatostatin analogues and the Tph1 inhibitor telotristat ethyl in severe cases.

Synthesis of Bimetallic BiPO/ZnO Nanocomposite: Enhanced Photocatalytic Dye Degradation and Antibacterial Applications.

Evidence revealing the role of T cell regulators (Tregs) in periodontal diseases: A review.

Periodontitis is an inflammatory disease of the periodontium, which is a reflection of the overgrowth of oral commensals. This alteration in the oral microbiota initiates inflammation of the gingiva, which when left untreated, terminates with the resorption of the alveolar bone that may lead to a poor and hopeless prognosis. With upcoming trends in modulating the host's immunity, the role of regulatory T-cells has gained importance.
