(açaí) fruit has approximately 15% pulp, which is partly edible and commercialized, and 85% seeds. Although açaí seeds are rich in catechins-polyphenolic compounds with antioxidant, anti-inflammatory, and antitumor effects-almost 935,000 tons/year of seeds are discarded as industrial waste. This work evaluated the antitumor properties of in vitro and in vivo in a solid Ehrlich tumor in mice.

Background: Breastfeeding maintains the maternal-fetal immune link after birth, favors the transmission of immunological competence, and is considered an important contributing factor to the development of the babies' immune system.

Objective: This study aimed to obtain data related to the effects of gestational diabetes on immunoglobulin A (IgA) and cytokines levels in the colostrum, before and during the pandemic of the new coronavirus, in order to study the possible outcomes regarding the immunological characteristics of human milk.

Methods: This systematic review was registered in PROSPERO CRD42020212397, and the question elaborated using the PICO strategy was: does maternal hyperglycemia associated or not with Covid-19 influence the immunological composition of colostrum? Electronic searching and reference lists of published reports were used to identify studies that reported the influence of gestational diabetes on colostrum and milk composition.

Praziquantel (PZQ) is the drug of choice for the treatment of all forms of schistosomiasis, although its mechanisms of action are not completely understood. PZQ acts largely on adult worms. This narrative literature review describes what is known about the mechanisms of action of PZQ against schistosomes from in vitro and in vivo studies and highlights the molecular targets in parasites and immune responses induced in definitive hosts by this drug.

Article Synopsis
  • This study investigates the antitumoral properties of a fungal extract sourced from a polluted lagoon in Northeastern Brazil.
  • The Ethyl Acetate Extracellular Extract (EAE) was tested on solid Ehrlich tumors in mice, showing significant tumor size reduction across various dosages (4, 20, and 100 mg/kg) while ensuring no harmful side effects.
  • The findings reveal that the extract is rich in meroterpenoids, supports immunomodulation, and suggests that fungal fermentation could be an effective method for developing new antitumor therapies.

The population widely uses babassu mesocarp () as food and medicine. This study evaluated the use of babassu mesocarp as a food supplement during resistance training (RT). Male Swiss mice, 60 days old (weight 35-40 g), were divided into four groups ( = 8): control, untreated and untrained; babassu (babassu aqueous extract [BAE]), treated orally with aqueous extract of babassu mesocarp (25 mg/kg), five times a week, for 8 weeks; training (RT), submitted to RT consisting of stair climbing with progressive loads; and resistance training treated with babassu aqueous extract (RTBAE): RT and treatment with BAE.

In an effort to identify novel therapeutic alternatives for the treatment of malaria, the present study evaluated the antimalarial effect of the crude hydroalcoholic extract (HCE) from the leaves of Chenopodium ambrosioides L. For this purpose, the molecular affinity between the total proteins from erythrocytes infected with Plasmodium falciparum and HCE or chloroquine was evaluated by surface plasmon resonance (SPR). Subsequently, the plasmodicidal potential of HCE was assessed in a P.

Background: The aim of this study was to evaluate the biochemical and immunological characteristics of saliva from diabetic patients compared to non-diabetic adults.

Methods: Eighty-eight diabetic adults and 39 non-diabetic adults (control) were included in the study. Glucose, urea, calcium, total protein and amylase were determined by a colorimetric method.

The immunomodulatory and anti-inflammatory activities of green propolis extracts from Apis mellifera were investigated using acute and chronic inflammation models. Swiss mice were anesthetized and a cotton pellet granuloma was implanted in subcutaneous tissue. Then the mice were divided into six groups and received apyrogenic water or different propolis extracts by oral route (5 mg/kg).
