1. Atlas of Mexican Triatominae (Reduviidae: Hemiptera) and vector transmission of Chagas disease
Chagas disease is one of the most important yet neglected parasitic diseases in Mexico and is transmitted by Triatominae. Nineteen of the 31 Mexican triatomine species have been consistently found to invade human houses and all have been found to be naturally infected with Trypanosoma cruzi. The present paper aims to produce a state-of-knowledge atlas of Mex

2. AplicaÃÃes da teoria dos grafos à teoria dos grupos / Applications of graph theory to group theory
This report deals with applications of Graph Theory to Group Theory. Once we construct the graph associated to a finite group, we get several interesting results on the group structure by analysing its associated graph with the help of various standard graph-theoretic tools. More precisely, the chromatic and independence numbers of the graph of a finite grou

3. Teoria de Ramsey para circuitos e caminhos / Ramsey theory for cycles and paths
The main objects of interest in this work are the Ramsey numbers for cycles and the Szemerédi regularity lemma. For graphs $L_1, \ldots, L_k$, the Ramsey number $R(L_1, \ldots,L_k)$ is the minimum integer $N$ such that for any edge-coloring of the complete graph with~$N$ vertices by $k$ colors there exists a color $i$ for which the corresponding color class

4. Chlamydia trachomatis Persistence in the Female Mouse Genital Tract: Inducible Nitric Oxide Synthase and Infection Outcome
It was previously reported that female mice resolve a primary Chlamydia trachomatis urogenital infection independent of inducible nitric oxide synthase (iNOS). We now report that although iNOS-deficient (NOS2−/−) mice resolve culture-apparent infection in a fashion similar to that of normal control (NOS2+/+) mice, they sustain significantly increased rat

5. Prior Genital Tract Infection with a Murine or Human Biovar of Chlamydia trachomatis Protects Mice against Heterotypic Challenge Infection
We sought to assess the degree of cross-protective immunity in a mouse model of chlamydial genital tract infection. Following resolution of genital infection with the mouse pneumonitis (MoPn) biovar of Chlamydia trachomatis, mice were challenged intravaginally with either MoPn or human serovar E or L2. The majority of animals previously infected with MoPn we

6. Resolution of chlamydial genital infection with antigen-specific T-lymphocyte lines.
To determine cell-mediated immune mechanisms involved in the resolution of chlamydial genital infection of mice, we utilized an established murine model in which it has been demonstrated that resolution of infection occurs independently of the antibody response. Splenic T lymphocytes were obtained from mice that had previously been immunized with viable elem
