Effectiveness of nutritional counseling with overweight pregnant women on child growth at 6 months: A randomized controlled trial.

Objective: Studies that have investigated the effect of nutritional counseling during the prenatal period on the follow-up outcomes of children at 6 mo have produced inconclusive results. The present study aimed to investigate the effect of nutritional counseling, based on the NOVA food classification, encouraging the consumption of fresh and minimally processed foods, with overweight adult pregnant women on infant growth at 6 mo of age.

Methods: A randomized controlled trial with 195 pairs of pregnant overweight women and their infants at 6 mo of age was conducted in a Brazilian municipality.

Soybean seed coat chitinase as a defense protein against the stored product pest Callosobruchus maculatus.

Background: Chitinases (EC 3.2.1.

Functional expression and activity of the recombinant antifungal defensin PvD1r from Phaseolus vulgaris L. (common bean) seeds.

Background: Defensins are basic, cysteine-rich antimicrobial peptides that are important components of plant defense against pathogens. Previously, we isolated a defensin, PvD1, from Phaseolus vulgaris L. (common bean) seeds.

New small proteinase inhibitors from Capsicum annuum seeds: Characterization, stability, spectroscopic analysis and a cDNA cloning.

Recent results from our laboratory have previously shown the purification of a small serine proteinase inhibitor (PI), named CaTI1, from Capsicum annuum seeds. This work demonstrated the characterization of CaTI now named CaTI1, and the identification of two other small serine PIs, named CaTI2 and CaTI3, also present in these seeds. CaTI1 presented molecular mass of 6 kDa and pI value of ∼9.

Antimicrobial peptides from Adenanthera pavonina L. seeds: characterization and antifungal activity.

In this study, the antifungal activity of peptides extracted from Adenanthera pavonina seeds was assessed. Peptides were extracted and fractionated by DEAE-Sepharose chromatography. The non-retained D1 fraction efficiently inhibited the growth of the pathogenic fungi.

Antifungal activity of PvD1 defensin involves plasma membrane permeabilization, inhibition of medium acidification, and induction of ROS in fungi cells.

In recent years, studies have demonstrated the function of many antimicrobial peptides against an extensive number of microorganisms that have been isolated from different plant species and that have been used as models for the study of various cellular processes linked to these peptides' activities. Recently, a new defensin from Phaseolus vulgaris (L.) seeds, named PvD(1,) was isolated and characterized.

Purification, biochemical characterization and antifungal activity of a new lipid transfer protein (LTP) from Coffea canephora seeds with α-amylase inhibitor properties.

Background: A growing number of cysteine-rich antimicrobial peptides (AMPs) have been isolated from plants and particularly from seeds. It has become increasingly clear that these peptides, which include lipid transfer proteins (LTPs), play an important role in the protection of plants against microbial infection.

Methods: Peptides from Coffea canephora seeds were extracted in Tris-HCl buffer (pH 8.

Soybean toxin (SBTX), a protein from soybeans that inhibits the life cycle of plant and human pathogenic fungi.

Soybean toxin (SBTX) is a 44 kDa glycoprotein that is lethal to mice (LD(50) = 5.6 mg/kg). This study reports the toxicity of SBTX on pathogenic fungi and yeasts and the mechanism of its action.

Purification of a defensin isolated from Vigna unguiculata seeds, its functional expression in Escherichia coli, and assessment of its insect alpha-amylase inhibitory activity.

Plant defensins make up a family of cationic antimicrobial peptides with a characteristic three-dimensional folding pattern stabilized by four disulfide bridges. The aim of this work was the purification and functional expression of a defensin from cowpea seeds and the assessment of its alpha-amylase inhibitory activity. The cDNA encoding the cowpea defensin was cloned into the pET-32 EK/LIC vector, and the resulting construct was used to transform Escherichia coli cells.

Isolation, characterization and cloning of a cDNA encoding a new antifungal defensin from Phaseolus vulgaris L. seeds.

The PvD1 defensin was purified from Phaseolus vulgaris (cv. Pérola) seeds, basically as described by Terras et al. [Terras FRG, Schoofs HME, De Bolle MFC, Van Leuven F, Ress SB, Vanderleyden J, Cammue BPA, Broekaer TWF.
