The aim of this study was to investigate tooth lead concentrations in a Spanish population living in Coruña, Spain. A total of 220 teeth were analysed using a microwave oven digestion procedure and lead content was measured by atomic absorption spectrometry. Samples were classified according to age, sex, type of tooth, cause of extraction and place of(More)
The purpose of this study was to determine the relationships of lead content in the human tooth with the prevalence of caries, dental plaque, pH of saliva, levels of Salivalis lactobacilli (SL) and Mutans streptococci (MS), degree of dental abrasion, tooth colour and toothbrushing frequency. A total of 220 teeth (one per person) were analysed using a(More)
The aim of this work is to provide a cross-cultural contribution to the study of gender differences in adolescent mood by providing the results of a random sample of 165 Argentinian boys and girls studied longitudinally by means of a survey at 13-14, 15-16 and 17-18 years old. Using Rosenberg's Depressive Affect Scale, the gender difference, larger than(More)
After arriving at an understanding that basic rights refer to all human needs, it is clear that a recognition of the basic needs of female humans must precede the realization of their rights. The old Women in Development (WID) framework only understood women's needs from an androcentric perspective which was limited to practical interests. Instead,(More)
The Latin American and Caribbean Regional Preparatory Meeting for the 1993 World Conference on Human Rights was attended by representatives from over 150 nongovernmental organizations (NGOs). The women's groups attending the preparatory meeting succeeded in developing a "women's platform" whose proposals were largely adopted by the main conference. The(More)
This paper examines the answers given by a random sample of 341 15- to 19-year old Argentinian adolescents, both male and female, in the 10th and 12th grades of high school in Paraná, to questions focusing on their relationship with their parents and formed part of a comprehensive survey on various aspects of their socio-emotional development.

This article discusses the Optional Protocol of the Convention on the Elimination of All Forms of Discrimination Against Women (CEDAW). This convention is the only instrument protecting the human rights of women at the international level. However, even if the convention was the best possible women's human rights documentation, there was no mechanism for(More)
Anticentromere antibodies are closely related to systemic sclerosis and basically to limited cutaneous form. Two patients with different forms of lung disease, positive anticentromere antibodies and absence of the characteristic skin involvement of the systemic sclerosis are presented.
The purpose of this study was to develop a new method for determination of the mineral element in teeth and bone using a microwave digestion procedure coupled to atomic absorption spectrometry. Samples were ashed at 450 degrees C for 4.5 h and subsequently digested in a microwave oven at maximum power (600 W) for 10 s using a Teflon closed Parr bomb. This(More)
