Dose-response effect of polyphenon-60 from green tea (P60-GT) on hexavalent chromium-induced genotoxic damage and apoptosis in mice.

This study aimed to examine the dose-response effects of polyphenon-60 derived from green tea (P60-GT) on hexavalent chromium [Cr(VI)]-induced genotoxic damage and apoptosis. Male Hsd:ICR mice were divided into 4 groups: (1) Control (vehicle only), (2) P60-GT (15, 30, or 45 mg/kg gavage), (3) Cr(VI) (20 mg/kg of CrO intraperitoneally), and (4) P60-GT+CrO (P60-GT administered 4 hr before CrO). Peripheral blood samples were collected at 24, 48, and 72 hr to assess the number of micronuclei (MN), apoptosis, and cell viability, while plasma 8-hydroxy-2'-deoxyguanosine (8-OHdG) levels were measured at 0 and 48 hr.

Seasonal Land Use and Land Cover Mapping in South American Agricultural Watersheds Using Multisource Remote Sensing: The Case of Cuenca Laguna Merín, Uruguay.

Recent advancements in Earth Observation sensors, improved accessibility to imagery and the development of corresponding processing tools have significantly empowered researchers to extract insights from Multisource Remote Sensing. This study aims to use these technologies for mapping summer and winter Land Use/Land Cover features in Cuenca de la Laguna Merín, Uruguay, while comparing the performance of Random Forests, Support Vector Machines, and Gradient-Boosting Tree classifiers. The materials include Sentinel-2, Sentinel-1 and Shuttle Radar Topography Mission imagery, Google Earth Engine, training and validation datasets and quoted classifiers.

Regarding the Pain of Others? Contradictions Between Public Discourse and the Lived Experience of Pain.

Background/objectives: Pain is a complex and subjective experience influenced by psychological, cultural, and social factors. This study aims to investigate how social perceptions of pain affect the lived experiences and coping mechanisms of individuals suffering from pain. By comparing public discourse with the experiences of sufferers, we explore whether the social legitimacy of pain influences how it is managed.

Structural and functional brain markers of cognitive impairment in healthcare workers following mild SARS-CoV-2 infection during the original stream.

Severe acute respiratory syndrome coronavirus 2 infection often involves the nervous system, leading to cognitive dysfunctions, fatigue and many other neurological signs that are becoming increasingly recognized. Despite mild forms of the disease accounting for most cases worldwide, research on the pathophysiology driving mild coronavirus disease 2019 (COVID-19) has received little attention. In this respect, recent evidence has pointed out that around 30-40% of non-critical, mild-to-moderate severity COVID-19 survivors may display cognitive disturbances several months post-illness.
