Human Papillomavirus (HPV) in cervical epithelium has been identified as the main etiological factor developing of Cervical Cancer (CC), which recently become a public health problem Mexico. This finding allowed for development vaccines that help prevent this infection. In present study, we aimed to determine prevalence and HPV type-distribution Mexican women with CC, high-grade squamous intraepithelial lesion (HSIL), low-grade (LSIL), Normal cytology (N) estimate impact vaccines.The PubMed...

The aetiological relationship between human papillomavirus (HPV) infection and cervical cancer (CC) is widely accepted. Our goal was to determine the prevalence of HPV types in Mexican women attending at Institute for Social Security from different areas Mexico.DNAs 2,956 samples were subjected genotyping: 1,020 with normal cytology, 931 low-grade squamous intraepithelial lesions (LGSIL), 481 high grade HGSIL 524 CC.Overall 67.1%. A total 40 found; HPV16 detected 39.4% HPV-positive followed...

Ten publicly available metagenomic data sets from hydrothermal vents were analyzed to determine the taxonomic structure of viral communities present, as well their potential metabolic functions. The type natural selection on two auxiliary genes was also analyzed. virome in quite different comparison with viruses present sediments, specific populations being greater abundance plume samples when compared sediment samples. ssDNA genomes such Circoviridae and Microviridae predominantly samples,...

We formulate a susceptible-vaccinated-infected-recovered (SVIR) model by incorporating the vaccination of newborns, vaccine-age, and mortality induced disease into SIR epidemic model. It is assumed that period immunity vaccines varies depending on vaccine-age. Using direct Lyapunov method with Volterra-type function, we show global asymptotic stability infection-free endemic steady states.

The relationship between Human Papillomavirus (HPV) infection and conjunctiva cancer is controversial. HPV detection will provide more information about the role of this infectious agent in biology cancer. In present study, DNA extracted purified from 36 Conjunctival Squamous Cell Carcinomas (CSCC) was evaluated by PCR for sequences. results were correlated with clinical histopathological variables.The showed that 8 CSCC samples (22%); HPV16 sole type detected. Significant association found...

Human papillomavirus (HPV) has been identified as the main etiological factor in developing of cervical cancer (CC). This finding propitiated development vaccines that help to prevent HPVs 16 and 18 infection. Both genotypes are associated with 70% CC worldwide. In present study, we aimed determine emergence high-risk nonvaccine HPV after actual vaccination scheme estimate impact current vaccines. A SIR-type model was used study dynamics vaccination.

BACKGROUND: Clinically non-functioning Pituitary Adenomas (NFPA) are among the most common neoplasms of sellar region. They usually present with compressive symptoms such as headache and visual field defects not infrequently, found incidentally. NFPA classified gonadotropinomas, null cell adenomas, according to their immunohistochemical phenotype. The molecular alterations responsible for development these lesions incompletely understood, there is scarce information regarding markers....

Introduction: In Head and Neck (HN) cancer, the High-Risk Human Papillomavirus (hr HPV) infection has been associated in about 40% of these tumors. The hr HPV is one etiological factors several epithelial tumors; however, its association with prognosis not yet established for patients Laryngeal Squamous Cell Carcinoma (LSCC). On other hand, Epidermal Growth Factor Receptor (EGFR) a molecular marker widely studied cancer overexpression poor some types including HN cancer. present study, we...

Abstract Human Papillomavirus (HPV) infection is the most common sexually transmitted disease in humans. About 200 HPV types have been described and classified into high low oncogenic risk for its ability to transform cell. Some main factors are multiple sexual partners, multiparity immunosuppression. However, these can not completely explain prevalence different world regions. Mexico has a global burden, being important determine other external biological implicated. The mediated by surface...
