The World Health Organization attracted more attention to the positive effects of physical activity (PA) and the adverse effects of stress on the health of older people and, therefore, attracted a more significant number of practitioners. To verify the impact of PA on stress in older people. Observational and analytical research, composed of 690 older people of both genders residing in Brazil, present in street races (as participants or observers), who volunteered to respond to the research protocol consisting of s [...]

(1) Background: Platelet function is commonly altered in liver cirrhosis. In experimenta models of liver cirrhosis we have analyzed the mechanisms of this defective function. (2) Methods: Experiments were performed in a model of liver cirrhosis by bile duct-ligation in washed platelets by means of fluorescence spectroscopy with fura-2. (3) Results: We have found several alterations compatible with the existence of a hyperaggregatory state. These alterations are related to a defective platelet calcium handling, spec [...]

There is growing scientific concern regarding how endocrine-disrupting chemicals (EDCs) impact central nervous system (CNS) disorders. Both anecdotal and preclinical studies suggest a link between EDC exposure and major depressive disorder (MDD), potentially leading to neurodegenerative outcomes. EDCs primarily exhibit their biological effects by interacting with hormone receptors. Nonetheless, there is scientific evidence pointing to dysfunction in the hypothalamic-pituitary-gonadal-adrenal axis, which is linked t [...]

Functional magnetic resonance imaging (fMRI) is widely used to detect changes in the resting-state brain networks of migraine patients. Functional connectivity fMRI analysis examines the functional organization of the brain based on temporal correlations of blood oxygen level-dependent signal changes in different brain regions. Most previous resting-state fMRI studies have assumed that functional connectivity between brain regions remains relatively stable over time. However, it is now known that the brain is a com [...]

This study conducted an in-depth analysis of the psychological states of teachers during the first outbreak of coronavirus disease 2019 (COVID-19) using data on school mental health projects related to COVID-19 in Daegu from May to June 2020. The participants comprised 811 (34.9%) male and 1,511 (65.1%) female teachers in 1,041 (44.8%) middle and 1,281 (55.2%) high schools. After schools reopened, the most common causes of unbearable stress were unusual experiences, fear of infection, and negative emotions. Moreove [...]

This article aims to provide some personal surgical tips to increase the success rate of deep anterior lamellar keratoplasty (DALK), a very advantageous yet complex procedure for treating keratoconus. The most troublesome surgical step is obtaining a successful pneumatic dissection of the deep stromal tissue, allowing the exposure of a deep cleavage plane. The following tips may aid the trainee surgeon in mastering this step, among others: performing a deep trephination, using intraoperative anterior segment optica [...]

The present article describes some characteristics of the effect of essential oil (EO) extracted from Ziziphora clinopodioides harvested from Armenian highlands on microglial cell lines (BV-2 wild-type (WT) and acyl-CoA oxidase1 (ACOX1)-deficient (Acox1–/–) cells). The mutant cell line was used as a model to investigate cellular oxidative damage following EO treatment. The main components of the tested EO were pulegone, isomenthone, 1,8-cineole, piperitone, and neomenthole, with concentrations of 42.1%, [...]

This citizen science project CLUE compared the attack frequency between school and vacation periods among adolescents. The data collection process adopted in citizen science projects opens up the possibility of conducting analyses by including a large number of participants over a long period and across different regions. The data on 684 migraine attacks reported by 68 adolescents aged 16 to 19 years were collected using an online platform and smartphone apps. A Fisher’s exact test was used to compare the distribut [...]

The objective of the present experimental study was to compare how young people, healthy older people, and older people with dementia cognitively integrated three factors (Intention, Consequence, and Apology) when making blame-like judgments (prosecution and revenge) and forgiveness-like judgments (resentment and reconciliation). Thirty-four young people (Mage = 22.12, SD = 3.44), 22 healthy older people (Mage = 71.82, SD = 8.69), and 18 older people with dementia (Mage = 75, SD = 10.06) participated in the study. [...]

Cancer continues to be one of the leading causes of global death, and conventional therapies have limited efficacy because of their toxicity, drug resistance, and off-target effects. Plant-derived nanoparticles (PDNPs) have emerged as suitable alternatives as they have biocompatibility, biodegradability, and multifunctional therapy. In this review, we discussed the recent advancements in PDNPs for cancer therapy, including the green synthesis of PDNPs using phytochemical (flavonoids, terpenoids) reducing and cappin [...]
