The karyotypes of Biomphalaria tenagophila collected from Rio de Janeiro, Brazil were studied using the air-drying method. Somatic cells of this species had 2n=36. The 18 chromosome pairs were identified and classified into 3 groups. The diploid cell has 7 pairs of metacentric, 8 pairs of submetacentric, and 3 pairs of subtelocentric chromosomes. Observed chromosomes ranged from 2.4 to 6.4 microm, and the total length was 122.3 microm. This is the first report on the chromosome of B. tenagophila.

Investigations of Enterobius sp. infection in prehistory have produced a body of data that can be used to evaluate the geographic distribution of infection through time in the Americas. Regional variations in prevalence are evident. In North America, 119 pinworm positive samples were found in 1,112 samples from 28 sites with a prevalence of 10.7%. Almost all of the positive samples came from agricultural sites. From Brazil, 0 pinworm positive samples were found in 325 samples from 7 sites. For the Andes region, 22 pinworm positive samples were found in 411 samples from 26 sites for a prevalence of 5.3%. Detailed analyses of these data defined several trends. First, preagricultural sites less frequently show evidence of infection compared to agricultural populations. This is especially clear in the data from North America, but is also evident in the data from South America. Second, there is an apparent relationship between the commonality of pinworms in coprolites and the manner of constructing villages. These analyses show that ancient parasitism has substantial value in documenting the range of human behaviors that influence parasitic infections.

Endometriosis is common estrogen-related gynecological diseases related to interactions of dietary, genetic causes, social and environmental factors. The high prevalence approaches 5-15% in premenopausal women and 30% in infertile women, and it is unusual to occur after the onset of menopause. In this review, the gene polymorphisms of estrogen receptor (ER) alpha and betare-lated to the risks of endometriosis were investigated through statistical analysis by using the gene polymorphism for the risks of the disease examined trends. The polymorphism of ERalpha-PvuII in Europe tends to increase the risk of endometriosis and, ERalpha-XbaI polymorphisms in both Asia and Europe have a slightly increased risk of endometriosis. In the case of ERbeta-RsaI, the risk of endometriosis increases in Brazil, while the polymorphism of ERbeta-AluI reduces the disease risks in Asia. Polymorphism studies on ER associated with the risk of endometriosis in Asia and Europe showed that those polymorphisms may be used to predict the high or low risks of endometriosis, and potentially used for prevention, therapy or prognosis of endometriosis. Further studies on interacting with more related genes and environmental factors may provide a better understanding of associations between estrogen receptor gene polymorphisms and endometriosis.

Detailed knowledge of the possible anatomical and morphometric variations of the infraorbital foramen (IOF) is important for ensuring safe and successful regional anesthesia, and for avoiding iatrogenic nerve injuries during surgery on the middle third of the face. To conduct a morphometric study on the IOF, correlating this with sex and side of the cranium. Two hundred forty-two crania were used (148 male and 94 female). Measurements were made with the aid of digital calipers with precision to 0.01 mm. Presence of foramina and their multiplicity was also observed. The data were analyzed descriptively and analytically. Statistical significance was stipulated as 5% (P≤0.05). The IOF was found bilaterally in all the crania, and 26 of them presented multiplicity. The distance from the IOF to the anterior nasal spine was greater in males on both sides (P<0.001). Statistical differences between the sexes were also seen in relation to the following morphometric variables: height of the left IOF (P=0.007), width of the right IOF (P=0.004), and width of the left IOF (P=0.008), and the measurements were also larger among males. The IOF was present in all the crania and on both sides. It was morphometrically larger in males, on both sides.

BACKGROUND: T. tonsurans is an anthropophilic dermatophyte mostly causing tinea capitis and tinea corporis. In East Asian countries, it has rarely been isolated until now. However, it is necessary for researchers in Asian countries to be more accustomed to T. tonsurans than before because of frequent international sports exchanges nowadays. OBJECTIVES: This study was performed to identify T. tonsurans by random amplified polymorphic DNA (RAPD) analysis. METHODS: Fifteen strains which were tentatively identified as T. tonsurans in Brazil were identified again by several conventional mycological tests and RAPD analysis. RESULTS: Among 15 Brazilian strains, 3 were identified as T. tonsurans, 8 T. mentagrophytes, 3 T. nJmwn and 1 T. raubitschekii by conventional mycological tests. This result was examined again by RAPD analysis. CONCLUSION: RAPD analysis is considered a rapid and reliable method for identification of T. tonsurans if the procedure is carefully standardized with adequate-primers.

While the use of radioactive materials around the world offers a wide range of benefits in medicine, industry and research, radiation accidents also occur in world-wide. The objective of this article is to provide useful information about radiation accidents to the medical personnel. For this, I attempted to document the circumstances leading to the accident and the subsequent medical treatment and health consequences of the victims. Radiation accidents described in this article are Chernobyl nuclear power plant accident, nuclear weapon accident in bikini atoll, major industrial accidents (Ir-192 Peruvian accident, Ir-192 internal contamination accident in Korea, Tokaimura accident in Japan) and Cs-137 contamination accident in Brazil. After reviewing major radiation accidents, I summarized the lessons to be learned from these accidents and presented the helpful institutes that can offer useful helps when radiation accident occurs.

Paleopathologists have begun exploring the pathoecology of parasitic diseases in relation to diet and environment. We are summarizing the parasitological findings from a mummy in the site of Lapa do Boquete, a Brazilian cave in the state of Minas Gerais. These findings in context of the archaeology of the site provided insights into the pathoecology of disease transmission in cave and rockshelter environments. We are presenting a description of the site followed by the evidence of hookworm, intestinal fluke, and Trypanosoma infection with resulting Chagas disease in the mummy discovered in the cave. These findings are used to reconstruct the transmission ecology of the site.

The review article presents some of the history of how paleoparasitology started in Brazil, making highlight the great responsible Dr. Luiz Fernando Ferreira and Dr. Adauto Araújo, the trajectory of paleoparasitology in Brazil since 1978 and its performance in science to the present day. In sequence, it is made a presentation of parasitological findings on human remains found in archaeological sites in South America, highlighting Brazil, Argentina, Chile, and Peru, where major discoveries have occurred. Many of the parasites found in archaeological material and mentioned in this review went out of Africa with the peopling of Europe and from there they dispersed around the world, where climatic conditions allow the transmission. However, humans have acquired other parasites of animals, since humans invaded new habitats or creating new habits adopting new technologies, thus expanding its range of influence on the environment. Thus, this review article is finalized with information that explain the importance of these findings in the interaction between parasites, human host, and ambient.
