Background: Abnormal uterine bleeding (AUB) is a common and distressing condition effecting predominantly perimenopausal women. Heavy menstrual (HMB) the most presentation of AUB. There are many structural non causes Histopathology endometrial curettings well studies before but histopathological patterns hysterectomy specimens not studied. Objective: The objective this study to: Find out diagno...

Silencing of transposons in the Drosophila ovary relies on three Piwi family proteins--Piwi, Aubergine (Aub), and Ago3--acting in concert with their small RNA guides, the Piwi-interacting RNAs (piRNAs). Aub and Ago3 are found in the germ cell cytoplasm, where they function in the ping-pong cycle to consume transposon mRNAs. The nuclear Piwi protein is required for transposon silencing in both g...

BACKGROUND: Canadian hysterectomy rates have declined in recent years. However, hysterectomy rates for discretionary indications, principally abnormal uterine bleeding (AUB), remain high in some regions. In northern Ontario, hysterectomy rates for women aged 34-45 are almost triple the rates in southern, urban areas. Primary care physicians (family doctors) usually manage AUB initially in these...

In Drosophila, Piwi proteins associate with Piwi-interacting RNAs (piRNAs) and protect the germline genome by silencing mobile genetic elements. This defense system acts in germline and gonadal somatic tissue to preserve germline development. Genetic control for these silencing pathways varies greatly between tissues of the gonad. Here, we identified Vreteno (Vret), a novel gonad-specific prote...

Introduction: Abnormal uterine bleeding (AUB) is considered as one of the most common problems both to the patient and the gynecologist. Until the pathology underlying atypical uterine bleeding is accurately diagnosed, proper therapy is hardly possible. The objectives of the study were to determine the types and frequencies of pathologies in endometrial curettings of abnormal uterine bleeding &...

Silencing of Stellate genes in Drosophila melanogaster testes is caused by antisense piRNAs produced as a result of transcription of homologous Suppressor of Stellate (Su(Ste)) repeats. Mechanism of piRNA-dependent Stellate repression remains poorly understood. Here, we show that deletion of Su(Ste) suppressors causes accumulation of spliced, but not nonspliced Stellate transcripts both in the ...

BACKGROUND AND AIMS Perimenopause is marked by clinical manifestations which disturb everyday life and which may also hide a pathomorphological, more precisely endometrial, substrate. An accurate early diagnosis established by accessible, non-invasive methods is very important for the therapeutic management. METHOD The study included 103 patients aged between 41.5-55.11 years, divided into 3 ...

OBJECTIVE The aim of our study is to determine clinical factors and sonographic findings associated with endometrial hyperplasia or cancer (EH+) in premenopausal and perimenopausal women. METHODS A total of 14,340 transvaginal ultrasonography examinations of 9,888 healthy premenopausal and perimenopausal women were included in this retrospective study. One hundred sixty-two subjects underwent...

The aim is to compare hysteroscopy, two-dimensional transvaginal ultrasound (2D TVUS), and three-dimensional (3D) Virtual Organ Computer-aided AnaLysis™ (VOCAL) to detect endometrial polyps (EPs) in premenopausal women with abnormal uterine bleeding (AUB). This prospective study was done at Ain Shams Maternity Hospital, Egypt, from March 5, 2015, to December 30, 2015, enrolling 118 premenopausa...
