EGF-receptor phosphorylation and downstream signaling are activated by genistein during subacute liver damage.

The epidermal growth factor receptor (EGFR) plays an important role on hepatic protection in acute and chronic liver injury. The aim of this study was to investigate the role of genistein on EGFR expression, phosphorylation and signaling pathways in experimental subacute liver damage induced by carbon tetrachloride (CCl). We used male Wistar rats that were randomly divided into four groups: (1) Control; (2) Genistein 5 mg/kg per oral; (3) Subacute liver damage induced by CCl 4 mg/kg subcutaneously; and (4) Animals received CCl and genistein at the dosage indicated.

The Receptor-Like Kinase PvFER1 and the Small Peptides PvRALF1 and PvRALF6 Regulate Nodule Number as a Function of Nitrate Availability.

Legumes associate with Gram-negative soil bacteria called , resulting in the formation of a nitrogen-fixing organ, the nodule. Nodules are an important sink for photosynthates for legumes, so these plants have developed a systemic regulation mechanism that controls their optimal number of nodules, the so-called autoregulation of nodulation (AON) pathway, to balance energy costs with the benefits of nitrogen fixation. In addition, soil nitrate inhibits nodulation in a dose-dependent manner, through systemic and local mechanisms.

Spontaneous Regeneration of Plantlets Derived from Hairy Root Cultures of and the Cytotoxic Activity of Their Organic Extracts.

A histological analysis was performed with the aim of elucidating the spontaneous regeneration process of the hairy root lines LRT 2.3 and LRT 6.4, derived from leaf explants and genetically transformed with the   strain ATCC15834/pTDT.

The ROP3 Is Involved in the Establishment of the Nitrogen-Fixing Symbiosis but Not of the Arbuscular Mycorrhizal Symbiosis.

Legumes form root mutualistic symbioses with some soil microbes promoting their growth, rhizobia, and arbuscular mycorrhizal fungi (AMF). A conserved set of plant proteins rules the transduction of symbiotic signals from rhizobia and AMF in a so-called common symbiotic signaling pathway (CSSP). Despite considerable efforts and advances over the past 20 years, there are still key elements to be discovered about the establishment of these root symbioses.

Analysis of self-reported adverse reactions to efavirenz and drug interactions in a population with HIV in Mexico.

Objective: To analyse the most frequent self-reported adverse reactions (ARs), the durability and the causes of antiretrovirals (ARVs) regimens change, concomitant treatments and drug interactions related to the use of ARVs in a group of people living with HIV in Cuernavaca, Morelos, Mexico.

Materials And Methods: Cross-sectional study conducted in a clinic specialising in HIV 'CAPASITS-Cuernavaca' in Mexico from February to June 2015. People who wanted to participate were given a questionnaire on demographic characteristics, adherence, concomitant treatments and ARs.

Genistein modifies liver fibrosis and improves liver function by inducing uPA expression and proteolytic activity in CCl4-treated rats.

Aim: To evaluate the effect of genistein on the fibrosis and matrix degradation caused by experimentally induced fibrosis in rats.

Methods: Hepatic fibrosis was brought about by chronic administration of carbon tetrachloride to rats. To evaluate the effect of genistein on liver fibrosis and function, total collagen content and proteolytic activity in the liver were quantified.

Genistein decreases liver fibrosis and cholestasis induced by prolonged biliary obstruction in the rat.

Fibrosis accompanies most chronic liver disorders and is a major factor contributing to hepatic failure. Therefore, the need for an effective treatment with the aim of modifying the clinical course of this disease is evident. The aim of this work is to determine whether genistein, which has been shown to modulate the physiology and pathophysiology of liver, is able to decrease experimental liver fibrosis and cholestasis.
