Chemical characterization, assessment of acute oral toxicity, and antinociceptive potential of the methanolic extract of (Arruda) Schott leaves from Brazil.

Background: (Arruda) Schott is popularly known as "aninga," "aningaçu," "aningaíba," and "aninga-do-igapó." Compresses and plasters made from the leaves of this medicinal plant are used to treat abscesses, tumors, and pain caused by stingray stings.

Aim Of The Study: This study aimed to chemically characterize the methanolic extract of leaves (MEMLL), as well as to verify their acute oral toxicity and antinociceptive potential.

Clinical-epidemiological assessment of patients undergoing bariatric and metabolic surgery in a medium-complexity service in Maranhão, Brazil.

Introduction: the obesity is defined as the excessive accumulation of fat in different areas of the body, a condition that causes damage to health and is a critical risk factor for various comorbidities. Bariatric surgery is the therapeutic option with the best results.

Methods: this is a retrospective descriptive study using data obtained from medical records from January 2018 to December 2020 on patients undergoing bariatric surgery.

Analgesic Activity of 5-Acetamido-2-Hydroxy Benzoic Acid Derivatives and an In-Vivo and In-Silico Analysis of Their Target Interactions.

The design, synthesis, and evaluation of novel non-steroidal anti-inflammatory drugs (NSAIDs) with better activity and lower side effects are big challenges today. In this work, two 5-acetamido-2-hydroxy benzoic acid derivatives were proposed, increasing the alkyl position (methyl) in an acetamide moiety, and synthesized, and their structural elucidation was performed using H NMR and C NMR. The changes in methyl in larger groups such as phenyl and benzyl aim to increase their selectivity over cyclooxygenase 2 (COX-2).

Chemical composition, antinociceptive and anti-inflammatory activities of the curzerene type essential oil of Eugenia uniflora from Brazil.

Ethnopharmacological Relevance: The Eugenia uniflora leaf infusion is widely used in folk medicine to treat gastroenteritis, fever, hypertension, inflammatory and diuretic diseases.

Aim Of The Study: This work evaluated the acute oral toxic, antinociceptive, and anti-inflammatory activities of the curzerene chemotype of Eugenia uniflora essential oil (EuEO).

Material And Methods: EuEO was obtained by hydrodistillation and analyzed by GC and GC-MS.

Chemical composition and antinociceptive and anti-inflammatory activity of the essential oil of Hyptis crenata Pohl ex Benth. from the Brazilian Amazon.

Ethnopharmacological Relevance: The leaf tea of Hyptis crenata has its practical use in the Brazilian Amazon for treating gastrointestinal and liver disorders, sweating induction, and as an anti-inflammatory.

Aim Of The Study: Evaluation of the chemical composition, acute oral toxicity, and antinociceptive and anti-inflammatory activities of the H. crenata essential oil.

Pellucidin A promotes antinociceptive activity by peripheral mechanisms inhibiting COX-2 and NOS: In vivo and in silico study.

Peperomia pellucida (PP) belongs to the Peperomia genus, which has a pantropic distribution. PP is used to treat a wide range of symptoms and diseases, such as pain, inflammation, and hypertension. Intriguingly, PP extract is used by different tropical countries for its anti-inflammatory and antinociceptive effects.

Portable model for vasectomy reversal training.

Objectives: to validate an experimental non-animal model for training of vasectomy reversal.

Materials And Methods: The model consisted of two artificial vas deferens, made with silicon tubes, covered by a white resin, measuring 10 cm (length) and internal and external diameters of 0.5 and 1.

Antinociceptive Activity and Toxicity Evaluation of the Fatty Oil from Plukenetia polyadenia Mull. Arg. (Euphorbiaceae).

Seed oil (Pp-oil) of Plukenetia polyadenia is used by native people of the Brazilian Amazon against arthritis and rheumatism, spreading it on the arms and legs to reduce the pain and inflammation. Pp-oil was obtained by pressing dried seeds at room temperature to give a 47.0% yield of oil.

Distalization controlled with the use of lip-bumper and mini-screw as anchorage: a new approach.

An increasingly number of patients with Angle Class II has been seeking orthodontic clinics to have their malocclusion treated. Herein, it is presented a new method of promote distal movements in maxillary molars with a combination of limp-bumper (LB) and mini screw. This technique was proven to be fast, practical and with low-cost, thus favoring both the professional and the patient.

Evaluation and theoretical study on the anti-inflammatory mechanism of 1-nitro-2-phenylethane.

In this study, 1-nitro-2-phenylethane was evaluated with respect to its effects in edema models of acute inflammation induced with carrageenan, dextran, and croton oil. 1-Nitro-2-phenylethane produced inhibition of rat paw edema induced by carrageenan and dextran at the doses of 25 and 50 mg/kg. The same doses caused an inhibition of croton oil-induced ear edema in mice.
