IN SILICO AND IN VITRO ASSESSMENT OF ANTI-Leishmania infantum ACTIVITY OF A NOVEL CYCLOHEXYL-1,2,4-OXADIAZOLE DERIVATIVE.

Globally, an estimated 1 billion people reside in endemic areas, and over 12 million individuals are infected with leishmaniasis. Despite its prevalence, leishmaniasis continues to be a neglected disease, mainly affecting underdeveloped countries. In Brazil, the available treatments are pentavalent antimonials and Amphotericin B, which are outdated, toxic, require prolonged parenteral administration and have limited efficacy.

A Probabilistic View of Forbidden Links: Their Prevalence and Their Consequences for the Robustness of Plant-Hummingbird Communities.

The presence in ecological communities of unfeasible species interactions, termed forbidden links, due to physiological or morphological exploitation barriers has been long debated, but little direct evidence has been found. Forbidden links are likely to make ecological communities less robust to species extinctions, stressing the need to assess their prevalence. Here, we used a dataset of plant-hummingbird interactions, coupled with a Bayesian hierarchical model, to assess the importance of exploitation barriers in determining species interactions.

Assessing diapocynin's different effects on osteosarcoma and breast cancer cells: An in vitro study.

Osteosarcoma is the most common primary bone cancer, accounting for approximately 5 % of new cancer cases globally. In contrast, breast cancer remains the most prevalent malignancy and a leading cause of cancer-related mortality among women. Given the limitations of current therapies, novel treatment strategies are urgently needed.

Investigating the stability of chalcone (2E)-1-(4-hydroxyphenyl)-3-(4-methoxyphenyl)-prop-2-en-1-one by Raman spectroscopy and computational calculations at high pressure.

Chalcones are organic substances that have diverse biological activities and exhibit potential for the treatment of various diseases. The properties of these substances depend on the type and position of the functional group attached to their aromatic rings. As a result, in this work the chalcone (2E)-1-(4-hydroxyphenyl)-3-(4-methoxyphenyl)-prop-2-en-1-one (CHO) was investigated by Raman spectroscopy and computational calculations at high pressures with the objective of analyzing its structural stability.

Behind the software: The impact of Unobtrusiveness, Goal Setting and persuasive features on BMI.

Background: Studies have demonstrated that interventions targeting weight loss and body mass index (BMI) reduction can be successful, although the specific factors that influence their effectiveness are still unclear. Behavior change support systems (BCSS) are an approach that aims to help users in their efforts to modify their behavior. A useful tool for assessing BCSS is the Persuasive Systems Design model (PSD), where different features and postulates can be employed.
