Toward Enhanced Antibiotic Efficacy: Exploring the Synergistic Potential of Marine-Derived Lectins Against Human Pathogenic Bacteria.

This study aimed to assess the combined antibacterial effect of lectins and antibiotics on S. aureus ATCC 25923, multidrug-resistant E. coli ATCC 11303 and S.

Chalcogen Bond-Driven Alkylations: Selenoxide-Pillar[5]arene as a Recyclable Catalyst for Displacement Reactions in Water.

A novel strategy to catalyze alkylation reactions through chalcogen bond interaction using a supramolecular structure is presented herein. Utilizing just 1.0 mol % of selenoxide-pillar[5]arene (P[5]SeO) as the catalyst we achieved efficient catalysis in the cyanation of benzyl bromide in water.

Hemipenial morphology of whiptail lizards Glaucomastix abaetensis and Glaucomastix littoralis , with comments on the genus Ameivula (Teiidae: Teiinae).

Hemipenes are important structures for the systematics of Squamata, and may assist in the diagnosis of closely related taxa. Only one of the species of Glaucomastix (G. venetacauda) had its hemipenial morphology described in literature so far.

Telluride-Based Pillar[5]arene: A Recyclable Catalyst for Alkylation Reactions in Aqueous Solution.

The syntheses of previously unknown sulfide- and telluride-pillar[]arenes are reported here. These macrocycles, among others, were tested as catalysts for alkylation reactions in aqueous solutions. Telluride-pillar[5]arene () showed the best performance, emulating the behavior of the methyltransferase enzyme cofactor -adenosyl-l-methionine.

Association between school context and occurrence of multiple sexual partners: cross-sectional study with multilevel analysis.

The objective was to investigate the association between the school context and the occurrence of multiple partners among adolescents, considering individual variables (age, gender, Bolsa Família, LGB, early sexual initiation and use of alcohol or drugs in the last sex). Cross-sectional study with multilevel analysis carried out in 2018 with adolescent students from Olinda, Brazil. The variable (multiple partners) was collected based on the 'Youth Risk Behavior Survey' questionnaire.
