In recent years, much attention has been paid to the use of biopolymers as food packaging materials due to their important characteristics and properties. These include non-toxicity, ease of availability, biocompatibility, and biodegradability, indicating their potential as an alternative to conventional plastic packag…

BACKGROUND AND OBJECTIVES: Diabetes mellitus is a serious metabolic disease that causes a serious economic burden worldwide. Gut flora is a major component of diabetes research, and the aim of this study was to understand the trends and major components of research related to diabetes and gut flora in the last 11 years…

Salter osteotomy is widely used to improve acetabular coverage in the treatment of developmental dysplasia of the hip. Herein we describe angulated Salter osteotomy (ASO) as the modified Salter osteotomy, which creates a two-point contact between the proximal and distal fragments and better stabilizes the fixation of t…

At the time of this writing, searching Google Scholar for 'light-sheet microscopy' returns almost 8500 results; over three-quarters of which were published in the last 5 years alone. Searching for other advanced imaging methods in the last 5 years yields similar results: 'super-resolution microscopy' (>16 000), 'single…

STUDY DESIGN: A retrospective study was conducted to analyze the data of patients with single stage Baerveldt glaucoma valve and Ah…

The budding yeast, Saccharomyces cerevisiae, is a powerful model system for defining fundamental mechanisms of many important cellular processes, including those with direct relevance to human disease. Because of its short generation time and well-characterized genome, a major experimental advantage of the yeast model…

INTRODUCTION: Acute upper gastrointestinal bleeding is the commonest emergency managed by gastroenterologists. It manifests like: haematemesis, melaena or haemochezia. Diagnostic endoscopy accurately defining the cause of haemorrhage, while therapeutic endoscopy improves prognosis in patients who present with severe bl…

A young patient with a severe and isolated memory disorder, meeting the criteria for MCI, was followed for a period of 8 years. His overall functional level remained stable with a CDR-score at 0.5 until the last year when it dropped to 1.0. Neuropsychological testing showed severe memory deficits but otherwise normal c…

OBJECTIVES: This study was undertaken to investigate time trends in early mortality, morbidity and clinical characteristics of patients undergoing heart valve surgery over the last decade. METHODS: A regional, prospectively collected, study comprising all patients (2,327) undergoing valve surgery in a defined geograph…

Mortality and amputation rates from acute arterial occlusion are reported from 7 to 37 per cent and 10 to 30 per cent, respectively. Recent data from thrombolysis or peripheral arterial surgery suggest no significant differences between initial management with surgical or thrombolytic therapy. Mortality and amputation…
