OBJECTIVE To determine the effects of a simple exercise program on the balance and strength of postmenopausal women with osteoporosis. METHODS This program was based on low intensity strength and balance exercises, and was carried out with simple, readily available equipment. Sixty five women were randomly assigned to either the experimental group (EG; n=33, age: 57.4±4.8 years) or the contro...

The unidentified, low-latitude, γ-ray source 3EG J1828+0142 presents high levels of variability and a steep spectral index Γ ∼ 2.7. Here we propose a model for this source where the high-energy emission is produced by a galactic Kerr-Newman black hole. The model takes into account electron-positron annihilation losses in the calculation of the expected spectral energy distribution and can repro...

This study examines the impact of a resistance-band functional exercise program, compared with a recreational exercise program, on physical fitness and reaction times in persons older than 60 years. Fifty-four community-dwelling volunteers (71.76 ± 6.02 years) were assigned to a specific exercise program: Functional activity program (focused on resistance-band multi-joint activities; experiment...

Systems for text retrieval, routing, categorization and other IR tasks rely heavily on linear classiiers. We propose that two machine learning algorithms, the Widrow-Hoo and EG algorithms, be used in training linear text classiiers. In contrast to most IR methods, theoretical analysis provides performance guarantees and guidance on parameter settings for these algorithms. Experimental data is p...

Patients with Brugada syndrome are at risk of life-threatening ventricular arrhythmias. Epicardial substrate ablation for Brugada syndrome has been described as a means of controlling these arrhythmias and recent reports describe elimination of the Brugada phenotype with ablation. We describe a unique case in which a patient developed inferior J waves with an early repolarization-type electroca...

THE anticipated value of the preoperative electrocardiogram for the assessment of perioperative cardiac risk has changed over the past decades. Initial risk scores included preoperative electrocardiogram variables as a prognostic factor for the occurrence of perioperative cardiac events; in recent years, however, the value of a routine preoperative electrocardiogram has been questioned. The cur...

La localisation et le delai d'apparition de changement de l'onde (T) a la suite de l'ingestion des boissens froide laisse supposer que le refroidissement se propage par con­tiguiter et n 'intresse que les couches superficielle de l'epi­carde. Ce qui peut expliquer !'apparition de l'onde (T) faiblement negative dans les derivation D3 et avf. 

Physical education (PE) teachers carry out resistance training programs at the beginning of a school year so that children can do other tasks safely during the whole course. However, after a few weeks of detraining, children revert back to their initial strength level. The purpose of this study was to evaluate the effects of a maintenance resistance training program on muscular strength in chil...

This study examined the effect of concurrent muscular strength and high-intensity running interval training on professional soccer players' explosive performances and aerobic endurance. Thirty-nine players participated in the study, where both the experimental group (EG, n = 20) and control group (CG, n = 19) participated in 8 weeks of regular soccer training, with the EG receiving additional m...

The possible identification by INTEGRAL of the EGRET source 3EG J1736 − 2908 with the active galactic nucleus GRS 1734−292 is discussed. The latter was discovered in 1990 and later identified with a Seyfert 1 galaxy. At the time of the compilation of the 3rd EGRET Catalog, it was not considered as a possible counterpart of the source 3EG J1736 − 2908, which remained unidentified. A detailed mul...
