Immune parameters, symptoms of upper respiratory tract infections, and training-load indicators in volleyball athletes.

Background: The control of immunological alterations becomes important during in-season training, as a result of increased incidence of infectious diseases, and may assist in avoiding interruptions to training due to illness.

Objective: The aim of the present study was to evaluate 28 weeks of chronic immune modulations in female volleyball athletes.

Methods: The sample was composed of twelve athletes aged 19.

Resistance training associated with the administration of anabolic-androgenic steroids improves insulin sensitivity in ovariectomized rats.

The aim of the present study was to investigate the effects of anabolic-androgenic steroids and resistance training (RT) on insulin sensitivity in ovariectomized rats. Adult female Wistar rats were divided into ten experimental groups (n = 5 animals per group): (1) sedentary (Sed-Intact); (2) sedentary ovariectomized (Sed-Ovx); (3) sedentary nandrolone (Sed-Intact-ND); (4) sedentary ovariectomized plus nandrolone (Sed-Ovx-ND); (5) trained (TR-Intact); (6) trained nandrolone (TR-Intact-ND); (7) trained ovariectomized (TR-Ovx); (8) trained ovariectomized plus nandrolone; (9) trained sham; and (10) trained ovariectomized plus sham. Four sessions of RT were used, during which the animals climbed a 1.

A protocol for efficiently retrieving and characterizing flanking sequence tags (FSTs) in Brachypodium distachyon T-DNA insertional mutants.

Brachypodium distachyon is emerging as a new model system for bridging research into temperate cereal crops, such as wheat and barley, and for promoting research in novel biomass grasses. Here, we provide an adapter ligation PCR protocol that allows the large-scale characterization of T-DNA insertions into the genome of Brachypodium. The procedure enables the retrieval and mapping of the regions flanking the right and left borders (RB and LB) of the T-DNA inserts and consists of five steps: extraction and restriction digest of genomic DNA; ligation of an adapter to the genomic DNA; PCR amplification of the regions flanking the T-DNA insert(s) using primers specific to the adapter and the T-DNA; sequencing of the PCR products; and identification of the flanking sequence tags (FSTs) characterizing the T-DNA inserts.

A protocol for Agrobacterium-mediated transformation of Brachypodium distachyon community standard line Bd21.

Brachypodium distachyon is a novel model system for structural and functional genomics studies of temperate grasses because of its biological and genetic attributes. Recently, the genome sequence of the community standard line Bd21 has been released and the availability of an efficient transformation system is critical for the discovery and validation of the function of Brachypodium genes. Here, we provide an improved procedure for the facile and efficient Agrobacterium-mediated transformation of line Bd21.

Barley transformation using Agrobacterium-mediated techniques.

Methods for the transformation of barley using Agrobacterium-mediated techniques have been available for the past 10 years. Agrobacterium offers a number of advantages over biolistic-mediated techniques in terms of efficiency and the quality of the transformed plants produced. This chapter describes a simple system for the transformation of barley based on the infection of immature embryos with Agrobacterium tumefaciens followed by the selection of transgenic tissue on media containing the antibiotic hygromycin.

High-throughput Agrobacterium-mediated barley transformation.

Background: Plant transformation is an invaluable tool for basic plant research, as well as a useful technique for the direct improvement of commercial crops. Barley (Hordeum vulgare) is the fourth most abundant cereal crop in the world. It also provides a useful model for the study of wheat, which has a larger and more complex genome.

Agrobacterium-mediated transformation of the temperate grass Brachypodium distachyon (genotype Bd21) for T-DNA insertional mutagenesis.

Brachypodium distachyon is a promising model system for the structural and functional genomics of temperate grasses because of its physical, genetic and genome attributes. The sequencing of the inbred line Bd21 (http://www.brachypodium.
