Antiproliferative potential and phenolic compounds of infusions and essential oil of chamomile cultivated with homeopathy.

Ethnopharmacological Relevance: Chamomilla recutita (Asteraceae) is used worldwide as a soothing, anti-inflammatory and aromatherapy. In Brazil, it is one of the most cultivated medicinal species. However, the cultivation form may alter the production of compounds in the secondary metabolism and compromise the therapeutic purpose of this species.

Assessment of the antiproliferative and antigenotoxic activity and phytochemical screening of aqueous extracts of Sambucus australis Cham. & Schltdl. (ADOXACEAE).

The purpose of this study was to evaluate the antiproliferative and antigenotoxic activity of Sambucus australis Cham. & Schltdl. aqueous extracts on the cell cycle of Allium cepa L.

Cytogenotoxicity of rice crop water after application of the tricyclazole fungicide.

Tricyclazole is currently one of the fungicides recommended for the treatment of diseases in irrigated rice. However, there is relatively little information on its cytotoxic and genotoxic potential. The objective of this study was to evaluate the cytotoxicity and genotoxicity of rice crop water after apllication of the tricyclazole fungicide through the Allium cepa L.

Association of Borage Oil and Betamethasone Dipropionate in Lipid-Core Nanocapsules: Characterization, Photostability and In Vitro Irritation Test.

The association of vegetable products to nanostructured systems has attracted the attention of researchers due to several advantages, such as drug photoprotection, as well as the improvement of the pharmacological and therapeutic activities because of synergistic action, which can provide their topical application. In this work, lipid-core nanocapsules containing borage oil as oil core and betamethasone dipropionate were developed, and nanocapsules without the drug were prepared for comparison. The suspensions were characterized in relation to mean particle size, zeta potential, pH, drug content, and encapsulation efficiency.

Post-treatment with plant extracts used in Brazilian folk medicine caused a partial reversal of the antiproliferative effect of glyphosate in the Allium cepa test.

Species of the genus Psychotria are used for multiple purposes in Brazilian folk medicine, either as water infusions, baths or poultices. This study was aimed to evaluate the genotoxic and antiproliferative effects of infusions of Psychotria brachypoda and P. birotula on the Allium cepa test.

Genotoxic effects of Campomanesia xanthocarpa extracts on Allium cepa vegetal system.

Unlabelled: CONTEXT. Campomanesia xanthocarpa Berg. (Myrtaceae), popularly known in Brazil as guabiroba, is a plant used as antidiarrheic, anti-inflammatory and antirheumatic agents, and in stomach and hepatic disorders.

Pollen viability of Polygala paniculata L. (Polygalaceae) using different staining methods.

Polygala paniculata L. is a medicinal plant that grows in the Brazilian Atlantic coast, known as 'barba-de-São-João', 'barba-de-bode', 'vassourinha branca', and 'mimosa'. In this study, pollen viability was estimated by three different staining methods: 2% acetic orcein, 2% acetic carmine, and Alexander's stain.

Biomonitoring genotoxicity and cytotoxicity of Microcystis aeruginosa (Chroococcales, cyanobacteria) using the Allium cepa test.

Water pollution caused by toxic cyanobacteria is a problem worldwide, increasing with eutrophication. Due to its biological significance, genotoxicity should be a focus for biomonitoring pollution owing to the increasing complexity of the toxicological environment in which organisms are exposed. Cyanobacteria produce a large number of bioactive compounds, most of which lack toxicological data.

Antiproliferative and genotoxic effects of Mikania glomerata (Asteraceae).

Mikania glomerata is a plant used in Brazilian traditional medicine, known as 'guaco'. It possesses anti-inflammatory properties and the aqueous extracts of its leaves are indicated for the treatment of diseases of the respiratory tract. This study aimed at evaluating the antiproliferative and genotoxic effect of Mikania glomerata leaf infusions on the cell cycle of onion.

Alterations in the mitotic index of Allium cepa induced by infusions of Pluchea sagittalis submitted to three different cultivation systems.

We evaluated the antiproliferative effect of infusions from Pluchea sagittalis using the Allium cepa test. Infusions in three concentrations (2.5, 5, and 25 g dm-3) of leaves cultivated in three environments (in vitro, acclimatized growth chamber, and field) were used.
