Maternal supplementation with Dipteryx alata Vog. modulates fecal microbiota diversity, accelerates reflex ontogeny, and improves non-associative and spatial memory in the offspring of rats.

Maternal diet plays a crucial role in offspring development, directly affecting neural development and gut microbiota composition. This study aimed to assess if baru almond and oil (Dipteryx alata Vog.) could modulate intestinal microbiota, brain fatty acid profile, and enhance memory in offspring of rats treated during early life stages.

Characterization and Determination of the Antibacterial Activity of Essential-Oil Nanoemulsions.

The aim of this study was to evaluate the antibacterial activity of nanoemulsions of essential oil. The volatile compounds of the essential oil were identified using gas chromatography-mass spectrometry. The properties of the nanoemulsions (droplet size, polydispersity index, pH, and electrical conductivity) were determined.

Insecticidal and Repellent Activities of Four Essential Oils Against (Coleoptera: Curculionidae).

Objective: This study aimed to evaluate the efficacy of , (Myrtaceae), × (Lamiaceae), and (Anacardiaceae) essential oils as an alternative to manage (Coleoptera: Curculionidae) adults.

Methods: Acute contact toxicity, acute toxicity on treated maize grain, fumigation toxicity, repellency bioassays, and GC-MS analysis of the essential oils were carried out.

Results: , , × , and oils were toxic at different levels to through residual contact, ingestion and via fumigation, and were also repellent to adults of this pest.

Effects of the healing activity of rosemary-of-Chapada (Lippia gracilis Schauer) on cutaneous lesions in rats.

Purpose: To evaluate the effects of rosemary leaf essential oil-based ointments on the healing of rat skin lesions.

Methods: Sixty adult male rats, with dorsal excisional skin wounds made surgically under anesthesia, were divided into three groups (n = 20): Sham group (untreated wounds); control group (CG, wounds treated with vehicle); and essential oil (EO) treated group (wounds treated with essential oil-based ointments), administered topically once daily. Skin wounds were evaluated at 4, 7, 14, and 21 days after EO or vehicle treatments.

Acaricidal activity of binary blends of essential oils and selected constituents against Tetranychus urticae in laboratory/greenhouse experiments and the impact on Neoseiulus californicus.

The aim of this study was to test the effectiveness of essential oils form Piper aduncum, Melaleuca leucadendra and Schinus terebinthifolius and their blends by fumigation and residual contact on Tetranychus urticae and its natural enemy, Neoseiulus californicus. Bioassays were performed in a greenhouse with the best blend of the oils and compared to the individual oils and Vertimec® (positive control). The main constituents identified by GC-MS were dillapiole, (E)-nerolidol and limonene in the oils from P.

Acaricidal property of the essential oil from Lippia gracilis against Tetranychus urticae and a natural enemy, Neoseiulus californicus, under greenhouse conditions.

The essential oil from the leaves of Lippia gracilis was investigated for fumigant and residual activity against Tetranychus urticae (Acari: Tetranychidae) and Neoseiulus californicus (Acari: Phytoseiidae). The results were compared to eugenol, Ortus and Azamax, as positive controls. Gas chromatography (GC) and GC/mass spectrometry analysis enabled the identification of 28 compounds, accounting for 99.

Schinus terebinthifolius Raddi ( Aroeira) leaves oil attenuates inflammatory responses in cutaneous wound healing in mice 1.

Purpose: To investigated the inflammatory, angiogenic and fibrogenic activities of the Schinus terebinthifolius Raddi leaves oil (STRO) on wound healing.

Methods: The excisional wound healing model was used to evaluate the effects of STRO. The mice were divided into two groups: Control, subjected to vehicle solution (ointment lanolin/vaseline base), or STRO- treated group, administered topically once a day for 3, 7 and 14 days post-excision.

Morphometric variations in the grasshopper, Chromacris speciosa from two localities of Pernambuco in northeastern Brazil.

Abstract The present study describes morphometric variations in the grasshopper, Chromacris speciosa (Thunberg, 1824) (Orthoptera: Acridoidea: Romaleidae) from two locations in the state of Pernambuco, Brazil. The distance between the sites chosen for collections (Recife and São Lourenço da Mata) is approximately 16 km. The investigation was based on a comparative study of external morphological characteristics of the grasshoppers.

Acaricidal and repellent activity of terpenoids from seaweeds Collected in Pernambuco, Brazil.

n-Hexane and dichloromethane extracts obtained from Laurencia dentroidea (Rhodophyta) and Canistrocarpus cervicornis (Phaeophyta) were investigated for their acaricidal and repellent properties against Tetranychus urticae under laboratory conditions. The two extracts displayed moderate toxicity and good repellent proprieties, and were significantly more toxic (36-fold) than the positive control (eugenol), whereas eugenol was tenfold more repellent than either seaweed extract. The sesquiterpenoid elatol (1) was isolated from L.

Essential oil composition and acaricidal activity of Schinus terebinthifolius from Atlantic Forest of Pernambuco, Brazil against Tetranychus urticae.

The compositions of the essential oils from unripe (UFr) and ripe (RFr) fruits of Schinus terebinthifolius were analyzed by GC and GC/MS. The major compound identified in both oils was limonene (UFr = 44.1 +/- 1.

Volatile constituents of two species of Protium from the Atlantic rainforest in the state of Pernambuco, Brazil.

The chemical composition of the essential oils from Protium giganteum and P. aracouchine was determined, for the first time, using GC-MS analysis. From the oil of P.

[From animal medical practitioners to veterinarians: historical note on animal medicine and the São Bento de Olinda Graduate School of Veterinary Medicine, Pernambuco (1912-1926)].

The historical aspects of animal medicine indicate an epistemological break with the old practices of animal medical treatment, with introduction of the principles of rationality in the eighteenth century in the formation of veterinary doctors. These healing practices, meanwhile, did not begin with the implementation of graduate courses in animal medicine. In colonial Brazil and, in particular, in the State of Pernambuco, historical records can be found of animal medical practices that were later incorporated into the curriculum of the São Bento de Olinda Graduate School of Veterinary, marked by the presence of a unique evaluation in Brazil: the physicum examination.
