Xiphidiocercariae from naturally infected Lymnaea columella (Mollusca, Gastropoda) in urban area: morphology and ultrastructure of the larvae and histological changes in the mollusc host.
Abstract
Urban agriculture is very common in the cities, as Rio de Janeiro and adjacencies, being important as economic activity. However, this practice can create appropriate conditions for establishment and maintenance of life cycle of many parasites. Lymneid snails can act as intermediate hosts of many trematodes species, including those that infect humans and wild and domestic. In the present study, the snail Lymnaea columella was collected from an urban watercress plantations and the morphology of cercariae released by them was analyzed by light and scanning electron microscopy. The specimens were ide...

Comparison of the phenolic contents and epigenetic and genetic variability of wild and cultivated watercress (Rorippa nasturtium var. aquaticum L.)
ConclusionsRelevant chemical, epigenetic, and genetic differences have emerged between wild and cultivated watercress. These differences can contribute to fingerprint and develop quality control tools for the integral and safety use and the commercialization of watercress. The richness of epialleles could support the development of tools to manipulate the watercress epigenome to develop high bioproduct–producing cultivars.How to cite: Gutiérrez-Velázquez MV, Almaraz-Abarca N, Herrera-Arrieta Y, et al.

Cu- and S- @SnO2 nanoparticles loaded on activated carbon for efficient ultrasound assisted dispersive µSPE-spectrophotometric detection of quercetin in Nasturtium officinale extract and fruit juice samples: CCD-RSM design.
Abstract
A simple, rapid, and efficient method of dispersive micro solid phase extraction (D-μ-SPE) combined with UV-Vis spectrophotometry via ultrasound-assisted (UA) was applied for the determination and preconcentration of quercetin in extract of watercress (Nasturtium officinale), fruit juice and water samples. The sorbent in this method was synthesized by doping copper and sulfide into the tetragonal structure of SnO2-nanoparticles (Cu- and S- @SnO2-NPs) and subsequently loading it on activated carbon (AC). The D-μ-SPE parameters with direct effect on the extraction efficiency of the targeted analyt...

Chemical composition, traditional and professional use in medicine, application in environmental protection, position in food and cosmetics industries, and biotechnological studies of Nasturtium officinale (watercress) - a review.
Abstract
The herb of Nasturtium officinale is a raw material that has long been used in the traditional medicine of Iran, Azerbaijan, Morocco and Mauritius. Nowadays, this raw material is the object of numerous professional pharmacological studies that have demonstrated its antioxidant, anticancer, antibacterial, anti-inflammatory and cardioprotective properties. These therapeutic effects are caused by glucosinolates present in the plant, isothiocyanates, polyphenols (flavonoids, phenolic acids, proanthocyanidins), terpenes (including carotenoids), vitamins (B1, B2, B3, B6, E, C) and bioelements. The artic...

Molecules, Vol. 23, Pages 1139: Profiling of Phenolic Compounds and Antioxidant Activity of 12 Cruciferous Vegetables
Choon Nam Ong
The phenolic profiles of 12 cruciferous vegetables (pakchoi, choysum, Chinese cabbage, kailan, Brussels sprout, cabbage, cauliflower, broccoli, rocket salad, red cherry radish, daikon radish, and watercress) were studied with UHPLC-MS/MS. Antioxidant activity and total phenolic content (TPC) were also evaluated. A total of 74 phenolic compounds were identified, including 16 hydroxycinnamic acids and derivatives, and 58 flavonoids and derivatives. The main flavonoids identified were glycosylated quercetin, kaempferol and isorhamnetin, and the main hydroxycinnamic acids were ferulic, sinapic, caffeic and p-...

1365 Interest of Biotrinine ®, a mix of Nasturtium officinale and Tropaeolum majus extracts, for chronic hair loss treatment
The hair follicle (HF) undergoes cycles of growth (anagen), regression (catagen) and resting (telogen) phases. Chronic hair loss is caused by the shortening of the active growing phase (anagen) and the extension of the quiescence phase (telogen) of the HF, which occurs mainly under the control of androgens that activate the expression of hair growth cycles inhibitors in dermal papilla cells. This imbalance leads first to the miniaturization of HFs, then to the loose of their ability to generate new hair shafts. (Source: Journal of Investigative Dermatology)
