Human papillomavirus as a single infection in pregnant women from Northeastern Mexico: Cross-sectional study.

Background: The role of human papillomavirus (HPV) as single or multiple infections in pregnant women would be relevant to determine the time to progression and/or the time to regression of cervical lesions.

Objective: In this preliminary study, we determined the prevalence of HPV as single or multiple infections in pregnant women from Northeastern Mexico.

Materials And Methods: Samples from 31 pregnant and 62 nonpregnant women were examined between January 2015 and November 2015 at UMAE-23 of the Instituto Mexicano del Seguro Social (IMSS).

Chromosome segregation and chromatin integrity in spermatozoa from a t(2;8)(p24;p21)mat carrier: A case-report.

Background: Chromosome rearrangements can produce genomic imbalance in gametes which causes a drastic decrease in fertility. Several studies have described the relationship between high levels of DNA damage and chromosomal alterations in the spermatozoa of infertile or subfertile males. However, the nature of this relation is poorly understood.

Mycobacterium tuberculosis promotes genomic instability in macrophages.

Background: Mycobacterium tuberculosis is an intracellular pathogen, which may either block cellular defensive mechanisms and survive inside the host cell or induce cell death. Several studies are still exploring the mechanisms involved in these processes.

Objectives: To evaluate the genomic instability of M.

Expression of leptin receptor in endometrial biopsies of endometrial and ovarian cancer patients.

The adipokine leptin plays a critical role in the regulation of reproductive function and there has been growing interest in its potential role in the development of cancers in which obesity is an established risk factor. Serum leptin levels were found to be higher in patients diagnosed with endometrial and ovarian cancer compared to those observed in healthy individuals. This study was conducted to determine the expression of the leptin receptor (Ob-R) in endometrial biopsies of patients diagnosed with endometrial and ovarian cancer.

Immunohistochemical analysis of prostate apoptosis response-4 (Par-4) in Mexican women with breast cancer: a preliminary study.

Background And Aims: We undertook this study to compare the expression level of prostate apoptosis response-4 (Par-4) among patient outcome in two groups of women with breast cancer (short and long survival) and two groups without breast cancer (benign lesion and control).

Methods: We included breast specimens with nonhistological abnormalities (eight samples) as a control group. Semiquantitative and quantitative analysis of immunohistochemical staining by image analysis software were used to study the intensity of Par-4 expression.
