The 2021 emergence of Brood X periodical cicadas Magicicada spp. (Hemiptera: Cicadidae) in Georgia, United States of America.

The US state of Georgia includes the range of several periodical cicada broods and is the southernmost state in which Brood X periodical cicadas emerge; however, no research has focused on this brood in this state. We used reports of sightings on social media, communication with the public, and our own searches to determine the geographic range in Georgia and timing of biological events. Both adults and exuviae were identified to species to determine the species makeup at those locations.

Clinicopathological Features and Mortality in Patients With Kaposi Sarcoma and HIV: A Retrospective Analysis of a Thirty-Year Study From a Peruvian Oncologic Center.

Purpose: Kaposi's sarcoma (KS) is a multifocal angioproliferative disease. In Peru, the implementation of the highly active antiretroviral treatment (HAART) program was in 2005, the model for treating patients with HIV-positive KS shifted to a potential cure. In this study, we aim to compare clinicopathological characteristics and prognostic factors associated with outcomes in patients with HIV-positive KS.

Physical activity and sedentary behavior in medical students at a Peruvian public university.

Introduction: Studies show a high prevalence of physical inactivity and sedentary behavior among university students. However, the relationship between physical activity and sedentary behavior in medical students is unknown.

Objectives: To determine the prevalence of physical activity, sedentary behavior, and related factors among medical students at a public university.

Silver supported on titania as an active catalyst for electrochemical carbon dioxide reduction.

Although significant research efforts have focused on the exploration of catalysts for the electrochemical reduction of CO2 , considerably fewer reports have described how support materials for these catalysts affect their performance, which includes their ability to reduce the overpotential, and/or to increase the catalyst utilization and selectivity. Here Ag nanoparticles supported on carbon black (Ag/C) and on titanium dioxide (Ag/TiO2 ) were synthesized. In a flow reactor, 40 wt % Ag/TiO2 exhibited a twofold higher current density for CO production than 40 wt % Ag/C.
