We report a spontaneous unilateral live tubal twin pregnancy in a patient with a history of previous ectopic pregnancy (EP) and tubal surgery. Transvaginal ultrasound showed one pregnancy sac containing two fetal poles with cardiac activity, which appeared to be sited within the right adnexum. The right tubal EP was removed by salpingectomy. Ultrasound findings of suspected adnexal mass and fre...

PURPOSE The purpose of this study was to determine whether walking with poles reduces loading to the lower extremity during level over ground walking. METHODS Three-dimensional gait analysis was conducted on 13 healthy adults who completed 10 walking trials using three different poling conditions (selected poles, poles back, and poles front) and without the use of poles (no poles). The invers...

Spindle poles are discernible by light microscopy as the sites where microtubules converge at the ends of both mitotic and meiotic spindles. In most cell types centrosomes are present at spindle poles due to their dominant role in microtubule nucleation. However, in some specialized cell types microtubules converge into spindle poles in the absence of centrosomes. Thus, spindle poles in centros...
