Children spend about five hours per day sitting down while doing their school work. Considering this as well as the potential inadequate use of school furniture, it is likely that some anatomical-functional changes and problems in the learning process may occur. The aim of this study was to examine possible incompatibility between students’ body measures and school chairs they use. A total of 6...

The seed coating technique adds value to the seeds. This allows changing size and shape, facilitating sowing, also application of essential nutrients good development plant in post-germination phases. Therefore, objective this work was evaluate physical physiological characteristics Stylosanthes capitata/macrocephala coated with different materials. For procedure, a N10 Newpack bench machine us...

objectives this study aimed to examine the relationship between patients’ anthropometric characteristics and depth of spinal needle insertion to the subarachnoid cavity. patients and methods 385 patients with asa class i – ii, aged 18 - 65 years and undergoing elective surgery of the lower abdomen and extremities under spinal anesthesia, were selected for this cross-sectional study. the patient...

Age at menarche is regarded as a sensitive indicator of physical, biological, and psychosocial environment. The aim of this study was to determine the age at menarche and its association with biological and socioeconomic factors in girls from Santa Rosa (La Pampa, Argentina). An observational cross-sectional study was carried out on 1,221 schoolgirls aged 9-15 years. Menarche data were obtained...

The acidities of multiple sites in the purine nucleobase adenine (1) and adenine alkyl derivatives 9-ethyladenine (2), 3-methyladenine (3), 1-methyladenine (4), and N,N-dimethyladenine (5) have been investigated for the first time, using computational and experimental methods to provide an understanding of adenine reactivity. We have previously measured two acidic sites on adenine, with the N9 ...

Biochemical and biological studies have been carried out with 2-desamino-2-methylaminopterin (dmAMT), which inhibits tumor cell growth in culture but is only a weak inhibitor of dihydrofolate reductase (DHFR). Since it was possible that the species responsible for growth inhibition are polyglutamylated metabolites, the di-, tri-, and tetraglutamates of dmAMT were synthesized and tested as inhib...

There is a specific anthropometric profile for each sport, which may be differentiated even in relation to the position, role or event category within each sport discipline. However, there are few studies on acrobatic gymnastics, and the goal of this work was to determine the anthropometric profile depending on the event category, as well as factors that predisposed to performance in these cate...
