Anti- Activity of Morolic Acid, a Pentacyclic Triterpene with Effects on Innate Immune Response during Macrophage Infection.

Leishmaniasis is a group of infectious diseases transmitted to humans during vector bites and caused by protozoans of the genus . Conventional therapies face challenges due to their serious side effects, prompting research into new anti-leishmania agents. In this context, we investigated the effectiveness of morolic acid, a pentacyclic triterpene, on promastigotes and amastigotes.

High percentage of midpiece defects in Brangus bull sperm with no reduction in sperm kinematics.

The study investigated midpiece defects in sperm from a 5-year-old Brangus bull with a high rate of semen batch rejection, due to morphologically abnormal sperm, with no reduction in sperm kinematics. A comprehensive evaluation was conducted over a 16-month period, involving 28 ejaculates. Notably, despite the high proportion of midpiece defects (average 37.

, first congeneric with the myrtle rust pathogen .

In 1895 and 2001, rust fungi affecting trees (Chrysobalanchaceae) in Brazil were described as by Hennings in the state of Goiás and as by Ferreira et al. in the state of Amazonas, respectively. Recently, a rust fungus collected close to the Amazonian type location sharing symptoms with the former two species was subjected to morphological examinations and molecular phylogenetic analyses using 28S nuc rDNA (ITS2-28S) and cytochrome oxidase subunit III (CO3) gene sequences.

Description of the puparium of Hermetia teevani Curran (Diptera, Stratiomyidae) reared from roots of cassava (Manihot esculenta Crantz).

The puparium of Hermetia teevani Curran is described, based on 173 specimens reared from cassava roots (Manihot esculenta), in laboratory under controlled conditions until the emergence of the adults. Hermetia teevani is the ninth species with immature stage known for Hermetia, in addition to being recorded for the first time for the Distrito Federal and State of Gois.
