New leishmanicidal products are needed for the treatment to be effective, since current drugs are toxic to healthy human/animal cells and have low efficacy against the parasite. Bioactive compounds from microalgae, such as lectins, can be explored as new anti-Leishmania candidates. This study aimed to evaluate the cytotoxic and anti-Leishmania action of the cell extract (CE) and lectin (CVU) from Chlorella vulgaris biomass.

Article Synopsis
  • Breastfeeding is crucial for neurodevelopment and early weaning has lasting negative effects on the mother-child bond and can lead to stress during infancy.
  • Early weaning disrupts neural mechanisms governing feeding behavior, leading to issues like overeating, increased body weight, and changes in hormonal regulation.
  • The review explores interventions like medication, herbal remedies, calcium, and physical activity to potentially mitigate the adverse effects of early weaning on feeding behavior control.

Article Synopsis
  • Previous research indicates that being overweight or obese can disrupt brain function during critical developmental phases, but more studies are needed on how immediate overnutrition affects serotonin in the brain.
  • This study investigates how altering serotonin levels with fluoxetine treatment in overnourished rats impacts oxidative stress and inflammatory markers in their brainstem and hypothalamus.
  • Findings suggest that overnutrition in early life leads to harmful changes in brain chemistry, but fluoxetine treatment can counteract some of these negative effects, supporting healthier brain development.

  • Schistosomiasis mansoni (SM) leads to periportal fibrosis (PPF) due to inflammation from parasite eggs, resulting in collagen and matrix protein buildup in the liver.
  • The study involved 242 individuals infected with S. mansoni in Pernambuco, Brazil, assessing the link between MMP-3 gene polymorphism (-1171 5A>6A) and PPF, alongside various sociodemographic factors.
  • Findings revealed no significant link between MMP-3 polymorphism and PPF; however, male gender and age over 41 were identified as predictors for the hepatosplenic form of the disease.

Flavonoids are secondary metabolites that exhibit remarkable biological activities, including antimicrobial properties against , a pathogen responsible for several serious nosocomial infections. However, oral administration of these compounds faces considerable challenges, such as low bioavailability and chemical instability. Thus, the encapsulation of flavonoids in nanosystems emerges as a promising strategy to mitigate these limitations, offering protection against degradation; greater solubility; and, in some cases, controlled and targeted release.
