2. Alterações no local de inserção e satisfação com o método entre usuárias de implantes contraceptivos subdérmicos / Local signs and symptoms at the site of insertion and women s evaluation of their satisfaction with two contraceptive implant systems
Objectives: The study was conducted to assess the prevalence of local signs and symptoms at the insertion site in the arm, and the evaluation of the women s satisfaction with the method and with the new bleeding patterns among users of subdermal releasing-implants, levonorgestrel (LNG, Jadelle®) and etonogestrel (ENG, Implanon®) systems. Methods: A total o

3. Quando nasce um bebê, nasce também uma mãe?: maternidade e reprodução humana assistida em mulheres laqueadas / When a baby is born, also a mother born? ": maternity and assisted human reproduction in sterilized women
In this thesis I analyze the trajectories of sterilized women who wish to have a new experience of maternity by means of assisted human reproduction, identifying the agents and socializing institutions which contributed to the decision taken. The analysis focuses on the understanding of how the trajectory is constructed, from the repentance of the original s

4. Relações entre estado e igreja na Argentina e no Brasil
This research paper focuses on the relations existent between the Catholic Church and the State. Such relationships are compared in Argentina and in Brazil. Through bibliographical and documental research, I have tried to identify the differences between the two States and their respective relationships with the Church. Questions such as the following were a

5. Porphyria cutanea tarda. Evolution study of the clinical and laboratory features: biochemistry, immunofluorescence and light microscopy / "Porfiria cutânea tardia. Estudo evolutivo das características clínicas e laboratoriais: bioquímica, imunofluorescência e microscopia óptica"
Porphyria cutanea tarda is caused by the inherited or acquired partial deficiency of the uroporphyrinogen decarboxylase enzyme activity, resulting in the accumulation of uroporphyrin and hepta-carboxyl porphyrinogen in the liver. The purpose of this study was to investigate the clinical and laboratory features: biochemistry and the alterations on skin morpho

6. Oral contraceptive use and prevalence of infection with Chlamydia trachomatis in women.
One thousand eight non-pregnant women aged 16-34 years, presenting for the first time at a clinic for sexually transmitted diseases (STD), were examined and screened for infection with Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and Candida species. The respective prevalence rates were 21.1%, 20.7%, 13.4%, and 27.8%. Isolation rates

7. No Interaction between Ciprofloxacin and an Oral Contraceptive
Several antibiotics have been reported to lessen the ovarian suppression produced by oral contraceptive agents, as a result of drug interactions. The present investigation was designed to study the likelihood of the occurrence of any such interaction between the fluoroquinolone antibiotic ciprofloxacin (Ciproxin) at a dosage of 500 mg twice a day and the “

8. Influence of augmented Hageman factor (Factor XII) titers on the cryoactivation of plasma prorenin in women using oral contraceptive agents.
Prolonged cold storage of plasma may induce the conversion of plasma prorenin (inactive renin) to renin. This phenomenon is exaggerated in oral contraceptive (OC) users; the titer of Hageman factor (HF, Factor XII) in OC users is higher than in nonusers. The present study relates these observations. The increment in plasma renin activity (PRA) during cold st

9. Iatrogenic endometrial patterns
The histological patterns exhibited in the endometrium due to the newer progestational agents cannot be correlated with the patient's menstrual cycle or the physiological endometrium which follows ovulation. The oral progestational agents which have been produced during the past few years have had wide clinical application. Although the 19-nor-steroids and t

10. Inactivation of Herpes Simplex Viruses by Nonionic Surfactants
Nonionic surface-active agents possessing ether or amide linkages between the hydrophillic and hydrophobic portions of the molecule rapidly inactivated the infectivity of herpes simplex viruses. The activity stemmed from the ability of nonionic surfactants to dissolve lipid-containing membranes. This was confirmed by observing surfactant destruction of mamma

11. Structure of Insoluble Rat Sperm Glyceraldehyde-3-phosphate Dehydrogenase (GAPDH) via Heterotetramer Formation with Escherichia coli GAPDH Reveals Target for Contraceptive Design*
Sperm glyceraldehyde-3-phosphate dehydrogenase has been shown to be a successful target for a non-hormonal contraceptive approach, but the agents tested to date have had unacceptable side effects. Obtaining the structure of the sperm-specific isoform to allow rational inhibitor design has therefore been a goal for a number of years but has proved intractable

12. Glyceraldehyde 3-phosphate dehydrogenase-S, a sperm-specific glycolytic enzyme, is required for sperm motility and male fertility
Although glycolysis is highly conserved, it is remarkable that several unique isozymes in this central metabolic pathway are found in mammalian sperm. Glyceraldehyde 3-phosphate dehydrogenase-S (GAPDS) is the product of a mouse gene expressed only during spermatogenesis and, like its human ortholog (GAPD2), is the sole GAPDH isozyme in sperm. It is tightly b
