the aim of this study is to compare three modes of femoral fixation, namely aperfix, rigidfix and endobutton, in anterior cruciate ligament (acl) reconstruction. 120 patients were randomly assigned to three groups, each consisting of 40 patients, and each group was treated by one of the above mentioned methods of femoral fixation. all patients were examined prior to and 24 months after surgery,...

OBJECTIVES We used the Doppler proximal flow convergence technique as a physiologic tool to explore the effects of the time courses of mitral annular area and transmitral pressure on dynamic changes in regurgitant orifice area. BACKGROUND In functional mitral regurgitation (MR), regurgitant flow rate and orifice area display a unique pattern, with peaks in early and late systole and a midsyst...

Introduction Annular pancreas (from the Latin annularis, meaning ring-shaped) is a rare congenital disorder of the pancreas first recognised by Tiedeman in 1818. This abnormality, although at times clinically silent, may be the cause of a broad spectrum of disease. Complications range from neonatal intestinal obstruction to more complex pathologies in the adult. In cases of neonatal obstruction...

conclusions although a leiomyosarcoma of the broad ligament is rare, practitioners should consider it when dealing with masses in the region of the broad ligament. if there is any suspicion of malignancy, especially in the presence of fever, it is recommended to avoid morcellation during laparoscopy. introduction leiomyosarcoma is a rare gynecologic malignancy that accounts for less than 1% of ...

Abstract—A functional microstrip circuit module for annular slot antenna is proposed. This module consists of an annular microstrip line component, two PIN diodes and a DC bias circuit. Reconfigurable circular polarizations can be simply controlled by this functional module. Axial ratio is adjustable by changing the clip angle of the notch made by the annular microstrip line component. Simulate...

BACKGROUND Mitral annular calcification has been associated with various systemic and cardiac diseases, with a higher prevalence in women and patients over 70. A possible association between mitral annular calcification and coronary artery disease has recently been suggested. OBJECTIVE To determine the prevalence of severe coronary artery disease in younger patients with mitral annular calcif...

Background: Mitral annular calcification has been associated with various systemic and cardiac diseases, with a higher prevalence in women and patients over 70. A possible association between mitral annular calcification and coronary artery disease has recently been suggested. Objective: To determine the prevalence of severe coronary artery disease in younger patients with mitral annular calcif...

Fluorescence quenching methods have been used to study interactions of anionic phospholipids with the potassium channel KcsA from Streptomyces lividans. Quenching of the Trp fluorescence of KcsA reconstituted into mixtures of dioleoylphosphatidylcholine (DOPC) and an anionic phospholipid with dibromostearoyl chains is more marked at low mole fractions of the brominated anionic phospholipid than...

OBJECTIVES Mitral annular calcification is associated with significant morbidity and mortality at the time of mitral valve surgery. However, few data are available describing the impact of mitral annular calcification on early and late outcomes following mitral valve repair in the current era. METHODS Between 2001 and 2011, 625 patients were referred for mitral valve repair of severe mitral r...
