Comparison of precision of a paperless electronic input method versus the conventional paper form in an andrology laboratory: a prospective study.

Background: Manual counting for semen analysis is recommended by the World Health Organization. Technicians performing this usually record their results on a paper worksheet and then enter the data into an electronic laboratory information system. One disadvantage of this approach is the chance of post-analytical transcription errors, which can be reduced by checking the computer entries before reporting by another technician.

Distribution of six oncogenic types of human papillomavirus and type 16 integration analysis in Chinese women with cervical precancerous lesions and carcinomas.

Objectives: The prevalent genotypes of human papillomavirus (HPV) infection and the significance of HPV16 integration in cervical precancerous lesions and cancer of Chinese women were investigated.

Methods: HPV genotyping and HPV16 integration status were studied on 100 normal cervical cytology, 90 low-grade (LSIL) and 99 high-grade squamous intraepithelial lesions (HSIL), as well as 96 cervical cancer biopsies using DNA sequencing and quantitative real-time PCR.

Results: HPV were detected in 12.

Potential use of the adenosine triphosphate cell viability assay in endometrial cancer.

Objective: Adenosine triphosphate cell viability assay (ATP-CVA) was used previously to evaluate chemotherapy in uterine cancer cell lines. In this study, we have performed the ATP-CVA on endometrial cancer patients to study the feasibility of using ATP-CVA in endometrial cancer to determine the intrinsic chemosensitivity of the cytotoxic drugs.

Methods: Thirty-three patients with endometrial adenocarcinoma who presented for a staging operation were recruited.

Differential DNA methylation profiles in gynecological cancers and correlation with clinico-pathological data.

Background: Epigenetic gene silencing is one of the major causes of carcinogenesis. Its widespread occurrence in cancer genome could inactivate many cellular pathways including DNA repair, cell cycle control, apoptosis, cell adherence, and detoxification. The abnormal promoter methylation might be a potential molecular marker for cancer management.

The increase of mitochondrial DNA content in endometrial adenocarcinoma cells: a quantitative study using laser-captured microdissected tissues.

Objective: Microsatellite instability (MSI) is a frequent genetic event in the D-loop region (which controls mitochondrial DNA (mtDNA) replication) of mitochondrial genome of endometrial cancer. We therefore investigated the relationship between mtMSI and mtDNA content in endometrial cancer.

Methods: Tumor tissues from 65 cancer patients and normal tissues from 41 non-cancer patients were used in this study.

Comparison of human papillomavirus DNA levels in gynecological cancers: implication for cancer development.

We have previously demonstrated the presence of human papillomavirus (HPV) DNA in several gynecological cancers using conventional PCR. In the present study, to further understand the role of HPV in malignant transformation of these cancers, the infection rates and viral loads of HPV 16 and 18 in gynecological cancers were analyzed using real-time quantitative PCR (qPCR). HPV 16 DNA was detected in 61.
