Adverse food reactions and alterations in nutritional status in children with autism spectrum disorders: results of the NAFRA project.

Background: To assess the adverse food reactions (AFR) prevalence in children with autism spectrum disorder (ASD) and in non-ASD healthy controls (NASD). Nutritional status alterations, food selectivity and adherence to Mediterranean Diet (MD) were also evaluated.

Methods: The NAFRA (Nutritional status and Adverse Food Reactions in children with Autism Spectrum Disorder) project was an observational, case-control, comparative study conducted at a tertriary center for pediatrics involving Caucasian patients of both sexes, aged 18 months-7 years, with a diagnosis of ASD, and matched NASD controls.

Transgenic sugarcane overexpressing CaneCPI-1 negatively affects the growth and development of the sugarcane weevil Sphenophorus levis.

Transgenic sugarcane expressing CaneCPI-1 exhibits resistance to Sphenophorus levis larvae. Transgenic plants have widely been used to improve resistance against insect attack. Sugarcane is an economically important crop; however, great losses are caused by insect attack.

SacRALF1, a peptide signal from the grass sugarcane (Saccharum spp.), is potentially involved in the regulation of tissue expansion.

Rapid alkalinization factor (RALF) is part of a growing family of small peptides with hormone characteristics in plants. Initially isolated from leaves of tobacco plants, RALF peptides can be found throughout the plant kingdom and they are expressed ubiquitously in plants. We took advantage of the small gene family size of RALF genes in sugarcane and the ordered cellular growth of the grass sugarcane leaves to gain information about the function of RALF peptides in plants.

Production of a His-tagged canecystatin in transgenic sugarcane and subsequent purification.

Transgenic plants have been used widely as expression systems of recombinant proteins in recent years. This process can be an efficient alternative for the large-scale production of proteins. In this work, we present the establishment of transgenic sugarcane expressing a His-tagged canecystatin under the control of the maize ubiquitin promoter.

Transcriptionally active transposable elements in recent hybrid sugarcane.

Transposable elements (TEs) are considered to be important components of the maintenance and diversification of genomes. The recent increase in genome sequence data has created an opportunity to evaluate the impact of these active mobile elements on the evolution of plant genomes. Analysis of the sugarcane transcriptome identified 267 clones with significant similarity to previously described plant TEs.
