Oxygen in the neonatal period: Oxidative stress, oxygen load and epigenetic changes.

Preterm infants frequently require positive pressure ventilation and oxygen supplementation in the first minutes after birth. It has been shown that the amount of oxygen provided during stabilization, the oxygen load, if excessive may cause hyperoxia, and oxidative damage to DNA. Epidemiologic studies have associated supplementation with pure oxygen in the first minutes after birth with childhood cancer.

The effect of short period high-intensity circuit training-modified FIFA 11+ program on physical fitness among young football players.

Background: Studies showed that FIFA 11+, the football injury prevention program, can improve physical fitness components through resistance and neuromuscular exercise. Currently, resistance training using High Intensity Circuit Training (HICT) is considered beneficial in increasing physical fitness component, including maintaining cardiopulmonary fitness. The purpose of this study was to evaluate the effect of HICT modified- FIFA 11+ training on the physical fitness components and cardiovascular (CV) training intensity of young football players.

Importance of the polarity of the glycosaminoglycan chain on the interaction with FGF-1.

Heparin-like saccharides play an essential role in binding to the fibroblast growth factor (FGF)-1 and to their membrane receptors fibroblast growth factor receptor forming a ternary complex that is responsible of the internalization of the signal, via the dimerization of the intracellular regions of the receptor. In this study, we report the binding affinities between five synthetic hexasaccharides with human FGF-1 obtained by surface plasmon resonance experiments, and compare with the induced mitogenic activity previously obtained. These five oligosaccharides differ in sulfation pattern and in sequence.

Effect of dsRNA on growth rate and reproductive potential of Monosporascus cannonballus.

The effect of double stranded RNA (dsRNA) infection on growth rate and the reproductive potential of Monosporascus cannonballus was studied in 21 isolates collected in cucurbit growing areas of Spain and Tunisia. The isolates were incubated on potato dextrose agar (PDA) under different conditions of temperature, pH, and water potential (Ψ(s)). They showed optimal growth temperatures over the range of 27-34°C and perithecia formation was obtained mainly at 25 and 30°C, although some isolates were able to produce perithecia at 35°C.

A Multiplex PCR System for the Specific Detection of Cylindrocarpon liriodendri, C. macrodidymum, and C. pauciseptatum from Grapevine.

Cylindrocarpon liriodendri and C. macrodidymum are the causal agents of grapevine black foot disease. Recently, a third species, C.

Genetic and Virulence Diversity in Verticillium dahliae Populations Infecting Artichoke in Eastern-Central Spain.

ABSTRACT Severe Verticillium dahliae attacks have occurred in artichoke crops in the Comunidad Valenciana region of eastern-central Spain since the late 1990s. Knowledge of genetic and virulence diversity in the pathogen population is a key factor for the management of the disease through disease risk assessment as well as development and use of resistant cultivars. V.

[Etanercept as a possible trigger of fatal pulmonary fibrosis].

Pulmonary fibrosis can be caused by external agents, including certain drugs. For some time now, tumor necrosis factor antagonists such as etanercept have been used to treat certain autoimmune diseases. Fibrosis caused by medication responds to withdrawal of the drug and treatment with corticosteroids.

Analysis of genetic and virulence diversity of Cylindrocarpon liriodendri and C. macrodidymum associated with black foot disease of grapevine.

Inter-simple sequence repeat (ISSR) analysis was used to investigate the genetic diversity of 87 Cylindrocarpon liriodendri and C. macrodidymum isolates, the causal agents of black foot disease of grapevine. The four ISSR primers (GT)7, (CCA)5, (CGA)5 and (TCG)5, were able to provide reproducible and polymorphic DNA fingerprint patterns and detected relevant genetic diversity in C.

Characterization of Fusarium circinatum from Pinus spp. in northern Spain.

Pitch canker caused by Fusarium circinatum was recently reported on Pinus spp. in Spain. In this study, a collection of 157 isolates of F.

[Arterial blood gases study in patients with stable chronic obstructive pulmonary disease in accordance with spirometric values].

Background And Objective: The aim of this study was to evaluate the need to assess arterial blood gases in patients with stable chronic obstructive pulmonary disease (COPD) in accordance with spirometric values.

Patients And Method: Transverse study in stable COPD patients with spirometry and pulse oximetry assessment. Specific exclusion criteria were: diagnosis of asthma, sleep apnea syndrome or respiratory failure not due to COPD.
