Background: Irresponsible and wholesale use of antimicrobial agents is the principal cause of the emergence of strains of resistant microorganisms to traditional drugs. Oligoventin is a neutral peptide isolated from spider eggs of Phoneutria nigriventer, with antimicrobial activity against Gram-positive, Gram-negative, and yeast organisms. However, the molecular target and pathways of antimicrobial activity are still unknown.

This study aims to evaluate the effects of pandemic-related training suspensions on the functional performance of U-20 soccer players from a first-division club in Rio de Janeiro.
Methods: Forty-one male U-20 soccer players were assessed during the preseason (PS) periods of 2020 and 2021.
HIV-induced AIDS attacks the immune system, leading to opportunistic infections. This syndrome has been linked to an increased risk of developing uveitis and subsequent cataracts. Consequently, cataract surgery may be associated with intra- and postoperative complications in HIV/AIDS patients.

- Conducted thermal treatment of dairy sludge at temperatures from 200 °C to 1000 °C to analyze its chemical composition and degradation, focusing on primary components like lactose and casein.
- Employed various analytical techniques, including X-ray diffraction and FTIR, to identify compounds formed during treatment, revealing significant changes in the organic and inorganic structures of the sludge.
- The study suggests that thermal plasma treatment can effectively transform dairy sludge into a vitreous slag, highlighting its potential for environmental management and waste neutralization.
Article Synopsis
- Cervical cancer is preventable but remains a major health issue for women in Brazil, with over 123,000 related deaths recorded from 2000 to 2021.
- A rising mortality trend was identified since 2014, especially among younger women and in the North and Northeast regions of Brazil, following a previous decline.
- The study highlights the need for targeted health policies to address regional disparities and improve prevention efforts in the areas and demographics most affected by cervical cancer.
