Mechanisms of herb-induced nephrotoxicity.

2013

Herbal therapies gained much popularity among the general public, but compared to therapies approved by official authorities, toxicological studies are frequently not available for them. Hence, there may be inherent risks and the kidneys may be especially vulnerable to toxic effects. Herbs may induce nephrotoxicity by induction of apoptosis. High oxalate contents in Star fruit (Averrhoa carambola L.) may induce acute nephropathy. Triptolide from Thunder God Vine (Triperygium wilfordii Hook) is a diterpenoid epoxide with induces reactive oxygen species and nephrotubular apoptosis. Cranberry juice is discussed as promoter of kidney stone formation (nephrolithiasis). Abuse of guaifenesin from …

Reconstruction of human subsistence and husbandry strategies from the Iberian Early Neolithic: A stable isotope approach

2018

Objectives The Early Neolithic involved an important social and economic shift that can be tested not only with the material culture, but also through biomolecular approaches. The Iberian Peninsula presents few Early Neolithic sites where fauna and humans can be analyzed together from an isotopic perspective. Here we present an isotopic study on the site of Cueva de Chaves as an example for understanding the dietary and economical changes that took place during Early Neolithic in Iberia. Material and methods Here we apply carbon and nitrogen stable isotope analysis to bone collagen from 4 humans and 64 faunal samples from 14 different species. The large dataset belongs to the same unique ch…

In vitro evolution of an atrazine-degrading population under cyanuric acid selection pressure: Evidence for the selective loss of a 47kb region on th…

2011

International audience; The adaptation of microorganisms to pesticide biodegradation relies on the recruitment of catabolic genes by horizontal gene transfer and homologous recombination mediated by insertion sequences (IS). This environment-friendly function is maintained in the degrading population but it has a cost which could diminish its fitness. The loss of genes in the course of evolution being a major mechanism of ecological specialization, we mimicked evolution in vitro by sub-culturing the atrazine-degrading Pseudomonas sp. ADP in a liquid medium containing cyanuric acid as the sole source of nitrogen. After 120 generations, a new population evolved, which replaced the original on…

A new autumn-flowering species of Allium (Alliaceae) from Croatia

2009

Here we describe Allium telmatum Bogdanovic, Brullo, Giusso & Salmeri, a new species of Allium sect. Codonoprasum from North Dalmatia (Croatia). Its chromosome number (2n = 32), karyotype, leaf anatomy, ecology and taxonomical relationships are examined. Several features, such as phenology (flowering in autumn), occurrence in coastal salt marshes, tetraploid chromosome number, and morphology, indicate that it is most closely related to the Tyrrhenian species Allium savii. On the basis of our herbarium survey, we present here a distribution map of the autumn-flowering species of Allium sect. Codonoprasum in the Mediterranean area.

Activation of Grapevine Defense Mechanisms: Theoretical and Applied Approaches

2011

part 4.; International audience; Grapevine, as other plants, possesses an innate immune system that usually prevents infection by pathogens. General elicitors are compounds of different biochemical families capable of inducing plant defense reactions. In grapevine, the cascade of defense events induced by elicitors has been studied among others in cell suspensions. The perception of the elicitor triggers signaling events that allow the activation of defense genes encoding PR proteins and other proteins involved in phytoalexin production and cell wall reinforcement. The grapevine phytoalexins resveratrol and derivated compounds have been largely studied. In addition to their antimicrobial ac…

Effetti del portinnesto sulla produttività e sulla qualità dell'anguria.

2010

The research aims to investigate the effects of different rootstocks on productive and qualitative aspects of two watermelon cultivars: Dumara, that produces big fruits and Minirossa that produces smaller fruits. For each cultivar, a randomized complete-block design was used with 3 replications to compare the following six grafting combinations: grafted plants into five rootstocks (Elsi, RS 841, Shintosa, Lagenaria corta, Anguria selvatica) and ungrafted plants. The highest yield of both cultivars was obtained with RS 841 while the lowest was observed with not grafted plants and grafted on elsi. However, using Elsi as rootstock, the plants gave fruits of greatest size. the best quality para…

Accidental poisoning with Aconitum: Case report and review of the literature

2020

Abstract Aconitine intoxication by ingestion of Aconitum roots can lead to ventricular tachycardia and cardiac arrest and provides an example of the potential effect of self‐medication. Educational campaigns should be implemented to contain acute intoxications caused by herbal‐derived products.

Abstract Soybean DAS‐44406‐6 expresses 5‐enolpyruvyl‐shikimate‐3‐phosphate synthase (2mEPSPS), conferring tolerance to glyphosate‐based herbicides, aryloxyalkanoate dioxygenase (AAD‐12), conferring tolerance to 2,4‐dichlorophenoxyacetic acid (2,4‐D) and other related phenoxy herbicides, and phosphinothricin acetyl transferase (PAT), conferring tolerance to glufosinate ammonium‐based herbicides. The molecular characterisation data and bioinformatics analyses did not identify issues requiring assessment for food/feed safety. The agronomic and phenotypic characteristics revealed no relevant differences between soybean DAS‐44406‐6 and its conventional counterpart, except for pod count, seed cou…
