UNLABELLED Calcium oxide, available for decades as a root canal filling material, has been little used in recent years due to its lack of radio-opacity, and an expectation that it would lead to an excess of root fractures. In this study, four general dentists submitted 79 cases of endodontically treated teeth whose roots were filled with either Biocalex 6/9, or Endocal-10, and rendered adequate...

INTRODUCTION Aseptic loosening is the commonest cause of failure of total joint replacements. The pathogenesis of this process remains controversial but appears to involve prosthetic migration, joint fluid pressure and the host response to particulate wear debris. The Swedish Hip Registry has shown that the type of bone cement used effects the risk of revision for aseptic loosening. It has been...

Introduction: Urolithiasis prevalence is approximately 15-20%, the third most common urological presentation to emergency departments (ED). In ED, renal stones are usually diagnosed by clinical presentation, but imaging modalities play a role in confirmation and exclusion of hydronephrosis. 85% calcium oxalate/calcium phosphate, which radio opaque, 15% radiolucent uric acid or cysteine stones. ...

Intragastric and intra-oesophageal pressures were recorded using water-filled "polythene " tubes of 2.5 mm. external diameter connected to an electromanometer of the capacitance type (N.E.P. Ltd.) and a two-channel direct writing pen recorder (Sanborn " twin-viso cardiette "). The recording end of each tube had a side hole about 1 cm. from the tip, the latter being closed off. The position of t...

BACKGROUND Yacon is a root crop which contains high amounts of fructooligosaccharides (FOS). The aim of this study was to investigate the effects of yacon syrup on colon transit time in healthy volunteers. METHODS In a placebo-controlled, double-blind study yacon was administered to 16 healthy individuals (8 males, 8 females) in a dose of 20 g daily (equal to 6.4 g FOS) in a 2-week crossover ...

BACKGROUND Gastrointestinal (GI) disturbances are often reported by long distance runners and are more common in women, particularly after prolonged high intensity exercise. OBJECTIVES To determine whether these symptoms could be associated with alterations in GI motility. METHODS Small bowel and colonic transit were measured using pH telemetry in a group of 11 female athletes (age 22 to 53...

A new method is described for measuring the mean transit time (MTT) of digesta through the human gut in which a constant amount of marker (radio-opaque pellets) is fed to subjects with each meal over a period of weeks, and its excretion measured in the stools. The MTT measured by this method (MTT-C) has been compared with MTT measured by giving single doses of similar markers to the same subjec...

INTRODUCTION A retained surgical sponge in the abdomen is uncommon although it is likely that this finding is underreported in the medical literature. The intravisceral migration of retained surgical gauze is even rarer, as demonstrated by the very few cases reported. CASE PRESENTATION Three years after undergoing anterior resection of the rectum, a 75-year-old man presented with symptoms of ...

New interesting astronomical science drivers for very low frequency radio astronomy have emerged, ranging from studies of the astronomical dark ages, the epoch of reionization, exoplanets, to ultra-high energy cosmic rays. Huge efforts are currently made to establish low frequency Earthbound instruments, since today’s technology is able to support this. However, astronomical observations with E...
