Biological Evaluation of Extracts from Argentina with Potent Cholinesterase Inhibition for the Treatment of Neurodegenerative Disorders and Their Comorbidities-The Case of Sm. (Caprifoliaceae) Studied in Mice.

Alzheimer's disease (AD) is a neurodegenerative disorder whose pathophysiology includes the abnormal accumulation of proteins (e.g., β-amyloid), oxidative stress, and alterations in neurotransmitter levels, mainly acetylcholine.

An overview on multi-elemental profile integrated with chemometrics for food quality assessment: toward new challenges.

Food products, especially those with high value-added, are commonly subjected to strict quality controls, which are of paramount importance, especially for attesting to some peculiar features related, for instance, to their geographical origin and/or the know-how of their producers. However, the sophistication of fraudulent practices requires a continuous update of analytical platforms. Different analytical techniques have become extremely appealing since the instrumental analysis tools evolution has substantially improved the capability to reveal and understand the complexity of food.

Dynamics of Polyphenol Biosynthesis by Calli Cultures, Suspension Cultures and Wild Specimens of the Medicinal Plant (Ruiz & Pav.) Tiegh. (Loranthaceae). Analysis of Their Biological Activity.

Neurobehavioral evaluation and phytochemical characterization of a series of argentine valerian species.

Folkloric or galenic preparations of valerian roots and rhizomes have been used as sedatives/anxiolytics and sleep inducers since ancient times. "Valerianas" are plants that naturally grow in our region. Although some of them are used in folk medicine, they lack scientific information.

Antioxidant Activity of Flavonoid Rich Fraction of Ligaria cuneifolia (Loranthaceae).

Ligaria cuneifolia (Ruiz & Pav.) Tiegh. (Loranthaceae), the 'Argentine mistletoe', is a hemiparasite species largely used in folk medicine.

Green spaces in a tertiary care children's hospital: Benefits, taxonomic survey, and perspective.

Humans coming in contact with natural green spaces experience beneficial physical, mental, and social effects. For the primary purpose of describing plant species found in the gardens of Hospital de Pediatría "Prof. Dr.

The Enriched Proanthocyanidin Extract of Ligaria cuneifolia Shows a Marked Hypocholesterolemic Effect in Rats Fed with Cholesterol-Enriched Diet.

Background: Ligaria cuneifolia (Lc) (R. et P.) Tiegh.

Development of a novel dual CD-MEKC system for the systematic flavonoid fingerprinting of Ligaria cuneifolia (R. et P.) Tiegh.-Loranthaceae-extracts.

The present work deals with the development and validation of a novel dual CD-MEKC system for the systematic flavonoid fingerprinting of Ligaria cuneifolia (R. et P.) Tiegh.

Effects of proanthocyanidin enriched extract from Ligaria cuneifolia on plasma cholesterol and hemorheological parameters. In vivo and In vitro studies.

Unlabelled: It was demonstrated that Ligaria cuneifolia (Lc) crude extract increased blood viscosity and decreased plasma cholesterol in rats. In the present study, we analyzed the Lc proanthocyanidin enriched fraction (PLc) to determine if it is capable of altering the hemorheological parameters while diminishing the plasma cholesterol. In vivo studies in adult male Wistar rats, randomized in three groups (n = 6 each one) were performed: 1.

Aqueous extracts of Lippia turbinata and Aloysia citriodora (Verbenaceae): assessment of antioxidant capacity and DNA damage.

The aim of the present work was to make a contribution to the knowledge of aqueous extracts of Lippia turbinata and Aloysia citriodora (Verbenaceae; infusion and decoction) in relation with the establishment of its antioxidant activity and lack of DNA damage, for its potential use in therapeutics. The cytogenotoxic profile was evaluated through genotoxic biomarkers such as mitotic index, cellular proliferation kinetics, sister chromatid exchanges, single-cell gel electrophoresis assay, and micronucleus test in human peripheral blood lymphocyte cultures. No statistical differences were found (P > .

Effect of Ligaria cuneifolia catechin- and quercetin-enriched fractions on hemorheology and plasma cholesterol.

Unlabelled: We tested the in vivo and the in vitro effects of both Ligaria cuneifolia catechin- and quercetin-enriched fractions on erythrocyte shape and deformability, and on plasma cholesterol level. For in vivo studies, adult male Wistar rats were randomized in three experimental groups which received intraperitoneally, once a day, 3 days:

Control: saline solution (C; n = 6); catechin from L. cuneifolia, 0.

Effect of the vehicle polyvinylpyrolidone and the Methanolic Fraction of Ligaria cuneifolia (Argentine Mistletoe) extract on hemorheological properties and biliary secretion in rats.

Ligaria cuneifolia flavonoid fractions modulate cell growth of normal lymphocytes and tumor cells as well as multidrug resistant cells.

Flavonoids are ubiquitous compounds present in plant extracts. They represent a major active component of the plant extract and are often known for their anti-inflammatory and anti-tumor effects. Previously, we demonstrated that Ligaria cuneifolia (R et P) Tiegh.

Hemorrheologic changes induced by aqueous extract of Ligaria cuneifolia: treatment by two different administration routes.

Inhibitory effect of medicinal herbs against RNA and DNA viruses.

Fifteen Argentine medicinal plants were tested for their antiviral activity in vitro against herpes simplex viruses types 1 and 2 (HSV-1 and 2), bovine viral diarrhoea virus type 1 (BVDV-1), influenza virus type A (Inf A) and human immunodeficiency virus type 1 (HIV-1). Antiviral activity was evaluated by a reduction in cytopathic effect, plaque-forming units and p24 HIV-1 antigen. The Selective Index of the active extract (SI(extract) = CC50(extract)/EC50(extract)) of Coronopus didymus (SI(extract) = 110.
