4. Us versus them, male and female: cross-cultural and sex-group comparisons in detecting coalitions and alliances / Nós versus eles, eles e elas: comparação intercultural e intersexual na detecção de coalizões e alianças
Duas visões diferentes podem ser identificadas na literatura sobre codificação de raça no processo de formação de primeiras impressões (categorização social): 1) A codificação de raça é um processo automático, inevitável e obrigatório; 2) é um processo dependente do contexto, que diminui com a explicitação de pistas visuais indicativas da

6. Sex differences in angiotensin II- induced hypertension
Sex differences in the development of hypertension and cardiovascular disease have been described in humans and in animal models. In this paper we will review some of our studies which have as their emphasis the examination of the role of sex differences and sex steroids in modulating the central actions of angiotensin II (ANG II) via interactions with free

7. Implicações do odor na percepção e escolha de parceiro
Why are we attracted to some people but not to other ones? How is this attraction established? Which signs are characteristic of a good partner? These and many other questions concerning how mate attraction and mate selection work out among humans have been intriguing behavioral scientists. It is well-known that beauty indicates something about a potential m

8. Cercarial Chaetotaxy and Sex Differentiation of Schistosoma mansoni Deriving from Humans and Nectomys squamipes (Muridae: Sigmondontinae) in Brazil
A comparative study was made between sympatric isolates of Schistosoma mansoni: one from a wild rodent (R) Nectomys squamipes and another one from humans (H) isolated from a low endemic schistosomiasis transmission area in Brazil. Our purpose was to detect differences between them concerning chaetotaxy (number and pattern of distribution of the argentophilic

9. Human toxocarosis. Its seroprevalence in the City of La Plata
Toxocara canis is very common in dogs throughout the world. It is the primary cause of visceral larva migrans (VLM) in humans. Soil contaminated with T. canis embryonated eggs is the main source of infection of man. Our objective was to describe Toxocara seroprevalence in humans in the city of La Plata associated with some determinants such asage, presence o

10. Sex Differences in the Expression of Hepatic Drug Metabolizing Enzymes
Sex differences in pharmacokinetics and pharmacodynamics characterize many drugs and contribute to individual differences in drug efficacy and toxicity. Sex-based differences in drug metabolism are the primary cause of sex-dependent pharmacokinetics and reflect underlying sex differences in the expression of hepatic enzymes active in the metabolism of dr

11. Sex-Associated Hormones and Immunity to Protozoan Parasites
Numerous epidemiological and clinical studies have noted differences in the incidence and severity of parasitic diseases between males and females. Although in some instances this may be due to gender-associated differences in behavior, there is overwhelming evidence that sex-associated hormones can also modulate immune responses and consequently directly in

12. Sex defines the age dependence of endogenous ACTH-cortisol dose responsiveness
Sex influences adrenal glucocorticoid responses to ACTH in experimental animals. Whether similar sex differences operate in humans is unknown. To test this notion, we estimated ACTH-cortisol dose-response properties analytically in 48 healthy adults (n = 22 women, n = 26 men), ages 18–77 yr, body mass index (BMI) 18–32 kg/m2, previously studied at two me
