Imprint of ancestral and modern threats in human mind - experience of fear, disgust, and anger.
Front Psychol

Department of Zoology, Faculty of Science, Charles University, Prague, Czechia.
Introduction: Threats to our survival are often posed by the environment in which humans have evolved or live today. Animal and human ancestors developed complex physiological and behavioral response systems to cope with two types of threats: immediate physical harm from predators or conspecifics, triggering fear, and the risk of infections from parasites and pathogens leading to the evolution of the behavioral immune system (BIS) with disgust as the key emotion. Here we ask whether the BIS has adapted to protect us from pandemic risks or poisoning by modern toxic substances.

Mucus is a complex hydrogel that acts as a defensive and protective barrier in various parts of the human body. The rise in the level of viral infections has underscored the importance of advancing research into mucus-mimicking hydrogels for the efficient design of antiviral agents. Herein, we demonstrate the gram-scale synthesis of biocompatible, lignin-based virus-binding inhibitors that reduce waste and ensure long-term availability.

Department of Biological Sciences, Faculty of Science, Kyambogo University, Kampala, Uganda.
Background: A key concern for global public health is nosocomial infections. Essential to the fight against nosocomial infection, is healthcare professionals' knowledge and attitudes. Therefore, this study investigated healthcare professionals' knowledge and attitudes toward nosocomial infection at the Kiruddu Referral Hospital, Kampala, Uganda.

Dogs can discriminate between people infected with SARS-CoV-2 from those uninfected, although their results vary depending on the settings in which they are exposed to infected individuals or samples of urine, sweat or saliva. This variability likely depends on the viral load of infected people, which may be closely associated with physiological changes in infected patients. Determining this viral load is challenging, and a practical approach is to use the cycle threshold (Ct) value of a RT-qPCR test.

Centro de Ciências Agrárias, Ambientais e Biológicas, Federal University of Recôncavo da Bahia, Cruz das Almas, Brazil.
Introduction: During the confinement in the COVID-19 pandemic, there was an increase in the production of urban waste, increasing the risk of accidents caused by scorpions. We sought to determine the clinical and epidemiologic aspects of scorpionism records in the 7 mesoregions of the State of Bahia, Brazil, examining differences in periods before and during the pandemic.
Methods: Data were obtained from SINAN, Brazil's Notifiable Diseases Information System (January 2010-December 2021).
