This study is devoted to investigating the stability of metal-organic framework (MOF)-hybrid perovskites consisting of CHNHPbI (MAPbI) and UiO-66 without a functional group and UiO-66 with different COOH, NH,and F functional groups under external influences including heat, light, and humidity. By conducting crystallinity, optical, and X-ray photoelectron spectra (XPS) measurements after long-term aging, all of the prepared MAPbI3@UiO-66 nanocomposites (with pristine UiO-66 or UiO-66 with additional functional groups) were stable to light soaking and a relative humidity (RH) of 50%. Moreover, the UiO-66 and UiO-66-(F) hybrid perovskite films possessed a higher heat tolerance than the other two UiO-66 with the additional functional groups of NH and COOH. Tthe MAPbI3@UiO-66-(F) delivered the highest stability and improved optical properties after aging. This study provides a deeper understanding of the impact of the structure of hybrid MOFs on the stability of the composite films.

Background: Sickle cell disease (SCD) confers neurological risks that contribute to cognitive and academic difficulties. Clinical guidelines state that cognition should be monitored using signaling questions. However, evidence is lacking regarding the extent to which signaling questions accurately identify children with cognitive issues.

Background: Proprioceptive deficits are common among stroke survivors and can negatively impact their balance and postural control. However, there has been little evaluation of the change in proprioceptive deficits in the lower limbs over time after stroke. This study aimed to examine proprioceptive deficits over time after stroke in both the affected and "unaffected" lower limbs.

Background: Nonpharmaceutical interventions for coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2, during the pandemic altered the epidemiology of respiratory viruses. This study aimed to determine the changes in respiratory viruses among children hospitalized from 2018 to 2023.

Methods: Nasopharyngeal specimens were collected from children aged under 15 years with fever and/or respiratory symptoms admitted to a medical institution in Fukushima Prefecture between January 2018 and December 2023.

Immune infiltration plays a significant role in the pathogenesis of rheumatoid arthritis (RA). Cuproptosis, a newly characterized form of programmed cell death, remains insufficiently investigated regarding its genetic regulation of immune infiltration in RA. Data from the GEO database were analyzed to determine the relationship between cuproptosis-related genes and immune infiltration.

As several decades of research have shown the cardioprotective effects of angiotensin-converting enzyme (ACE) inhibitors alone or in combination with diuretics, we were interested in investigating the effects of subchronic therapy of these drugs on ischemia-reperfusion (I/R) damage to the heart, as well as their influence on oxidative status. The research was conducted on 40 spontaneously hypertensive male Wistar Kyoto rats, divided into 4 groups. Animals were treated for four weeks with 10 mg/kg/day zofenopril alone or in combination with hydrochlorothiazide, indapamide and spironolactone per os.
