introduction: functional gastrointestinal disorders (fgid) are non-fatal, unknown etiology disorders with absence of a structural or biochemical explanation and accounting for up to 50% of gastroenterology referrals. infant regurgitation, rumination and cyclic vomiting constitute the vomiting disorders. abdominal pain disorders are classified as: functional dyspepsia, irritable bowel syndrome (...
The orbicularis oculi reflex was studied in 48 comatose patients and the results were correlated with clinical and pathological findings. The late component of the reflex was absent or of minimal amplitude in all cases regardless of the site of lesions, reflecting a diffuse suppression of the reticular system rather than a specific or local block in the brain-stem. Alteration of the early compo...
Mechanical ventilation can cause structural and functional disturbances in the lung, as well as other vital organ dysfunctions. Apoptosis is thought to be a histological sign of distant organ damage in ventilator-induced lung injury (VILI). Nakos and colleagues observed a protective effect of prone positioning against VILI in normal sheep. Less alteration in the lung architecture and function a...
Background: The special role of health service providers in coping with the crisis is undeniable. However, there is lack of a research studying the crisis management of the operating rooms. The aim of this study was to evaluate the situation of crisis management in operating rooms of hospitals affiliated to Tehran University of Medical Sciences. Methods: In this descriptive cross-sectional stud...
The expression of functional proteins in heterologous hosts is a cornerstone of modern biotechnology. Unfortunately, proteins are often difficult to express outside their original context. They might contain codons that are rarely used in the desired host, come from organisms that use non-canonical code or contain expression-limiting regulatory elements within their coding sequence. Improvement...
In these notes we give a brief introduction to Kolmogorov complexity. The notes are based on the two talks given at KAM Spring School, Borová Lada, 2006.
Due to the influence of load, fatigue, corrosion, natural material aging and other long-term adverse factors, the state of the internal force of a cable-stayed bridge will be changed. These long-term effects can result in the bridge not meeting specified functional requirements, and potentially resulting in structural failure. This investigation focuses on the parameter identification of a gird...
In this paper, the structural, magnetic, and electronic properties of two- to nine-atom copper and silver clusters and their alloys with one palladium atom are investigated by using full-potential all-electron density functional computations. After calculating minimized energy of several structural isomers of every nanocluster, it is argued that the small size nanoclusters (up to size of 6), ...
OBJECTIVE In this study we investigated the relationship between synovial vascularity (SV) and structural alteration of finger joints in patients with RA and long-term sustained clinical low disease activity (CLDA). METHODS RA patients with CLDA of >2 years (minimum 1 year of CLDA for study entry plus 1 year of observation) were analysed. Quantitative SV values were sequentially measured in e...
Building waste is a critical issue in current construction. Innovative design strategies are required to reduce the depletion of valuable materials and resources through providing flexible and versatile structures. This study focuses on the development of an industrial, flexible, and demountable wall panel construction system. The panel system consists of concrete blocks with steel connectors t...
