Sports tourism downturn: The impact of COVID-19 on Chinese tourism among urban and rural residents under epidemic.

Background: China's sports tourism has seen significant growth since the 2008 Olympics, only to be challenged by the coronavirus disease 2019 pandemic. This study aims to assess the impact of the pandemic on China's tourism and sports tourism, which are highly interrelated.

Method: Data and materials from 2019 to mid-2023 were systematically collected and analyzed, focusing on seasonal tourism reports published on official local networks in China.

Transcriptomic and multi-cytokines profile analysis revealed new insights into the integrating mechanisms of cyanidin-3-O-glucoside on male reproductive damage amelioration.

Ulcerative colitis is a public health issue with a rising worldwide incidence. It has been found that current medications for treating UC may cause varying degrees of damage to male fertility. Our previous study demonstrated that cyanidin-3-O-glucoside (C3G) treatment could effectively restore reproductive damage in a mouse model of DSS induced colitis.

Bacteria inhabiting spider webs enhance host silk extensibility.

Spider silk is a promising material with great potential in biomedical applications due to its incredible mechanical properties and resistance to degradation of commercially available bacterial strains. However, little is known about the bacterial communities that may inhabit spider webs and how these microorganisms interact with spider silk. In this study, we exposed two exopolysaccharide-secreting bacteria, isolated from webs of an orb spider, to major ampullate (MA) silk from host spiders.

Toxicity Studies and Inactivation of SARS-CoV-2 by Povidone-iodine Gel Forming Formulations.

To curb the spread of SARS-CoV-2, the etiologic agent of the COVID-19 pandemic, we characterize the virucidal activity of long-acting Povidone Iodine (PVP-I) compositions developed using an gel forming technology. The PVP-I gel forming nasal spray (IVIEW-1503) and PVP-I gel forming ophthalmic eye drop (IVIEW-1201) rapidly inactivated SARS-CoV-2, inhibiting the viral infection of VERO76 cells. No toxicity was observed for the PVP-I formulations.
