Population-based targeted sequencing of 54 candidate genes identifies as a susceptibility gene for high-grade serous ovarian cancer.

Purpose: The known epithelial ovarian cancer (EOC) susceptibility genes account for less than 50% of the heritable risk of ovarian cancer suggesting that other susceptibility genes exist. The aim of this study was to evaluate the contribution to ovarian cancer susceptibility of rare deleterious germline variants in a set of candidate genes.

Methods: We sequenced the coding region of 54 candidate genes in 6385 invasive EOC cases and 6115 controls of broad European ancestry.

The colposcopic feature ridge sign is associated with the presence of cervical intraepithelial neoplasia 2/3 and human papillomavirus 16 in young women.

Objective: Interobserver and intraobserver correlation between the colposcopic phenomenon ridge sign and its association with cervical intraepithelial neoplasia (CIN) 2 or 3, with a specific human papillomavirus (HPV) type, and with the age of the patient.

Study Design: Colpophotographs, cervical smears, and histologic results of punch or cone biopsies of 592 patients were evaluated. Colpophotographs were analyzed retrospectively for the presence or absence of an opaque acetowhite ridge at the squamocolumnar junction (ridge sign) by 3 gynecologists of different experience.

Inner border--a specific and significant colposcopic sign for moderate or severe dysplasia (cervical intraepithelial neoplasia 2 or 3).

Objective: Investigation of the correlation between the colposcopic sign inner border and cervical intraepithelial neoplasia (CIN) 2 or 3 and its association with specific human papillomavirus (HPV) types and the age of the patient.

Study Design: Colpophotographs or cervicograms were taken from 947 women referred due to an abnormal cervical finding. Occurrence of the colposcopic sign inner border was evaluated retrospectively by 2 independent colposcopists.

Detection of high-risk cervical intraepithelial neoplasia and cervical cancer by amplification of transcripts derived from integrated papillomavirus oncogenes.

Cervical cancer emerges from cervical intraepithelial neoplasia (CIN) induced by high-risk HPV (HR-HPV) infections. However, the vast majority of CIN lesions regresses spontaneously, and only a few lesions persist or progress to invasive carcinoma. On the basis of morphological criteria, it is not possible to differentiate high-grade lesions that will regress or persist from those that inevitably will progress to invasive cancers.

The amino acid sequence of dog (Canis familiaris) hemoglobin.

The manual sequencing of the tryptic peptic from the alpha and beta chains of dog hemoglobin is described, including evidence for the existence of two alphaT-13 peptides and thus 2 alpha chains, one with threonine and one with alanine at position 130. Although the actual sequence was published in 1970, the evidence on which it was based has not previously appeared.

Hemoglobin Willamette (alpha2beta2 51Pro replaced by Apg (D2)) a new abnormal human hemoglobin.

A hemoglobin variant with the same electrophoretic mobility as hemoglobin S was found in three generations of a black family. No clinical symptoms or findings were present in subjects heterozygous for this mutant. Except for target forms of mature erythrocytes, they have no abnormal hematologic findings.
