Synthesis of an imine-type nickel complex and investigation of its electrocatalytic activity for H evolution.

We report on the synthesis and characterization of an imine-type nickel complex produced the complexation of an generated 2-(iminomethyl)phenol ligand with Ni ion. The use of this complex as an electrocatalyst for H evolution in a DMF solution, with acetic acid as the proton source, was investigated in detail, employing both experimental analyses (electrochemical analysis, spectroscopy analysis) and theoretical analysis (plateau current analysis). The overpotential required for H evolution is about 590 mV with a faradaic efficiency of 49% after 3 hours bulk electrolysis, competing with the two-electron reduction of free-imine groups in the ligand.

Stem Cell Therapy for the Treatment of Amyotrophic Lateral Sclerosis: Comparison of the Efficacy of Mesenchymal Stem Cells, Neural Stem Cells, and Induced Pluripotent Stem Cells.

Background/objectives: (ALS), or Lou Gehrig's disease, is a debilitating, incurable neurodegenerative disorder characterised by motor neuron death in the spinal cord, brainstem, and motor cortex. With an incidence rate of about 4.42 cases per 100,000 people annually, ALS severely impacts motor function and quality of life, causing progressive muscle atrophy, spasticity, paralysis, and eventually death.

The Impact of Vaccination on COVID-19 Outcomes in Vietnam.

: This study aimed to assess the effectiveness of the COVID-19 vaccine on the outcomes of patients in three hospitals in Vietnam. : An observational study involved 3102 confirmed COVID-19 patients from Vietnam. Participants were classified into unvaccinated, partially vaccinated (one dose) (PV), fully vaccinated (two doses) (FV), and boosted (three doses) groups.

Pets and related allergens modify the association between early life DEHP exposure and respiratory outcomes in children.

Introduction: Throughout the perinatal period children are exposed to complex mixtures, including indoor chemicals such as phthalates, and biological agents. However, few studies focus on interactions between early-life co-exposures to shed light on how co-exposures modify their individual effects. Therefore, our study aims to assess whether early-life exposure to pets and related biological agents, namely pet allergens and endotoxin, modifies the association between di-(2-ethylhexyl) phthalate (DEHP) and asthma and wheeze in preschoolers to gain insight into interactions.

Effects of Socioeconomic Status and Healthcare Resource Availability on Survival in Older (≥66 years) Non-Hispanic Black Patients Versus Non-Hispanic White Patients With Multiple Myeloma.

Background: Several factors contribute to the known disparities in overall survival (OS) between non-Hispanic Black (NHB) patients and non-Hispanic White (NHW) patients with multiple myeloma (MM).

Patients And Methods: To explore whether socioeconomic status (SES) and healthcare resource (HCR) availability impacts OS, this retrospective study used linked Surveillance, Epidemiology, and End Results (SEER)-Medicare claims and Area Health Resource Files to identify NHB and NHW patients aged ≥66 years with MM (newly diagnosed 6/1/2013-12/31/2017). Continuous Medicare A and B enrollment until 12/31/2019 or preceding death was required.
