Amphotericin B induces apoptosis-like programmed cell death in Naegleria fowleri and Naegleria gruberi.

Naegleria fowleri and Naegleria gruberi belong to the free-living amoebae group. It is widely known that the non-pathogenic species N. gruberi is usually employed as a model to describe molecular pathways in this genus, mainly because its genome has been recently described.

Prevalence of human papillomavirus in women from Mexico City.

Introduction: Cervical cancer is the most common cancer among Mexican women. The goal of the present study was to determine the prevalence and distribution of HPV types in women from Mexico City.

Methods: Our study was conducted in the Clinica de Especialidades de la Mujer de la Secretaría de la Defensa Nacional, Mexico.

In vivo programmed cell death of Entamoeba histolytica trophozoites in a hamster model of amoebic liver abscess.

Entamoeba histolytica trophozoites can induce host cell apoptosis, which correlates with the virulence of the parasite. This phenomenon has been seen during the resolution of an inflammatory response and the survival of the parasites. Other studies have shown that E.

Entamoeba histolytica: differential gene expression during programmed cell death and identification of early pro- and anti-apoptotic signals.

We have demonstrated that programmed cell death (PCD) in Entamoeba histolytica is induced in vitro by G418 aminoglycoside antibiotic. To ascertain if biochemical and morphological changes previously observed are paired to molecular changes that reflect a genetic program, we looked here for early differential gene expression during the induction of PCD. Using cDNA-amplified fragment length polymorphisms (AFLPs) and in silico derived analysis we showed in E.

[Diagnosis of infection Chlamydia trachomatis by PCR among patients in the Specialty Clinic of Women of the National Defense Secretary].

Introduction: Infection with Chlamydia trachomatis is a sexually transmitted bacterial disease most common in the world.

Material And Methods: Determination through the PCR technique the presence of C. trachomatis in 98 cervical samples by amplifying a fragment of DNA plasmid cryptic.
