Nychthemeral rhythmicity of urinary copper (Cu) was studied in 40 clinically healthy volunteers and 35 renal stone formers.
A marked diurnal rhythm was noticed in urinary Cu levels in healthy subjects with maximum excretion at 0000 to 0600 hr followed
by a progressive fall during the rest of the period reaching minimum between 1200 to 1800 hr in males and 0600 to 1200 hr
in female volunteers. Similarly, all stone patients exhibited a definite rhythm in urinary Cu with significant amplitude and
acrophases at 2145 hr for males and 2141 hr for female stone formers. However, there was no difference in mean 24-hr Cu excretion
in male and female stone formers, whereas a significant change was observed in case of healthy subjects. Urinary Cu was found
to be significantly increased in renal stone formers in comparison to healthy controls of either sex attributing a significant
role of this overlooked trace mineral in the crystallization and/or activation of either of the process of stone formation
in the renal tubules. 相似文献

What should children and young adolescents read? Recent changes in the English curriculum have once again shifted the focus towards more canonical texts, but does featuring such texts on the course necessarily equate to rigorous teaching and in-depth learning? Through a self-examination of her own reading history, the author argues for a dialogic approach to reading and text selection instead, so that students may negotiate better understandings of themselves and their own socio-cultural contexts. 相似文献

Abstract Promoting self-determination has become an important aspect of the educational programs of students with disabilities. There is now a sufficient literature base to support some syntheses that enable researchers to judge their progress in this area to date and to provide direction for future research and practice. For this study, we conducted a literature review of studies that measured or examined global self-determination. 相似文献

The ancient unsolved problem of congruent numbers has been reduced to one of the major questions of contemporary arithmetic: the finiteness of the number of curves over Q which become isomorphic at every place to a given curve. We give an elementary introduction to congruent numbers and their conjectural characterisation, discuss local-to-global issues leading to the finiteness problem, and list a few results and conjectures in the arithmetic theory of elliptic curves. 相似文献

The problem of pesticides is not new and its exposure to human due to indiscriminate use is largely associated with the health related problems including neurotoxicological alterations. High levels of pesticide residues and their metabolites in the dietary constituents, food materials, maternal blood, cord blood, placenta breast milk have been reported and linked to alterations in birth weight, crown heel length, head circumference, mid-arm circumference and ponderal index of the neonates. Epidemiological studies have suggested that exposure of pesticide to human could be a significant risk factor for neurological disorders, including Parkinson’s disease, Alzheimer’s disease and multiple sclerosis. Cholinergic and non-cholinergic dysfunctions in pesticide exposed population, especially in children have also been frequently reported in recent years. Developmental neurotoxicity is another concern in the area where pregnant are more prone towards its exposure and which results in the abnormalities in the fetus. In view of the increasing risk of human health through pesticide exposure, the present review has been focused on the studies pertaining to pesticide induced neurochemical alterations and associated behavioral abnormalities in farm workers which could establish a possible link between the its exposure and associated health hazards. 相似文献

Torsades de pointes with prolonged QTc interval is a form of ventricular tachycardia. Many predisposing factors have been identified and hypocalcemia is among the rare ones. Our case illustrates that though rare, hypocalcemia might manifest as torsades de pointes with prolongation of QTc interval. Early diagnosis and management of dyselectrolytemia can prevent these patients from catastrophic torsades de pointes. 相似文献

Arsenic contamination of ground water has become a serious problem all over the world. Large number of people from Uttar Pradesh, Bihar and West Bengal of India are suffering due to consumption of arsenic contaminated drinking water. Study was carried out on 30 individuals residing in Ballia District, UP where the maximum concentration of arsenic was observed around 0.37 ppm in drinking water. Blood samples were collected from them to find out the problem related with arsenic. Cytogenetic study of the blood samples indicates that out of 30, two persons developed Klinefelter syndrome. 相似文献

Although education is identified as a key determinant of economic development and poverty eradication, this relationship is only possible when educationists are able to provide a comprehensive picture of the educational process in working life. In this paper it is argued that if systems of education and training are to cater to both the formal and the informal labour markets, then they need to take into account the traditions and values of the system of vocational learning in working life, cater to the requirements of local development and be based on an understanding of the kinds of competencies people in the informal economy want, need and utilise, the socio-economic and cultural contexts within which they work, and how they cope and sustain their livelihood strategies. 相似文献
