Background and objectives In accordance with clinical findings, myringoscterosis develops after otitis media (OM) and paracentesis in an experimental setting. The pathogenesis of this phenomenon of calcification is poorly understood. As the calcification process and the sclerotic plaques of the drum mimics features of bone tissue, this study explores tympanic membrane calcium deposition in associa
The Scandinavian countries - Denmark, Norway, Sweden and Finland - have developed a particular model of welfare, employment and economic governance. It is based on universal access to tax-financed social services and social insurance, full employment secured by expansive macro-economic policies and active labour market policies, highly organized labour markets, corporatist interest mediation, and
Background: The nephrotoxic potential of anti-glomerular-basement-membrane (GBM) antibodies has been demonstrated in numerous animal experiments. However, it is not known to what extent the properties of circulating anti-GBM antibodies in human disease reflect the severity of the disease and predict the outcome. Methods: Clinical data were collected for 79 Swedish patients for whom a positive resu
A case study of congenital esophageal stenosis is reported. Light microscopic examination revealed extensive disorganization of the inner circular muscle layer, with partial absence of the muscularis mucosae.
Boolean functions are used as nonlinear combining functions in certain stream ciphers. A Boolean function is said to be correlation immune if its output leaks no information about its input values. Balanced correlation immune functions are called resilient functions. Finding methods for easy construction of resilient functions with additional properties is an active research area.

An aqueous two-phase system, consisting of poly(ethylene glycol) (PEG) and dextran, was employed to separate polymerase chain reaction (PCR)-inhibitory substances from bacterial cells. The PCR inhibition of four soft cheeses was examined and three of them were found to be strongly PCR-inhibitory. Extraction of the PCR-inhibitory soft cheeses inoculated with Listeria monocytogenes in an aqueous two
Primary headaches such as migraine are among the most prevalent neurological disorders, affecting up to one-fifth of the adult population. The scientific work in the last decade has unraveled much of the pathophysiological background of migraine, which is now considered to be a neurovascular disorder. It has been discovered that the trigemino-cerebrovascular system plays a key role in migraine hea
Simultaneous saccharification and fermentation of wood to ethanol has often been claimed to be less sensitive to infection than separate hydrolysis and fermentation. A previous study has shown that this was not the case. In the present study the influence of different parameters in SSF, such as cell concentration, nutrient composition and inclusion of the liquid from pretreatment, on the ethanol y
Hypertension has been associated with increased case-fatality rates among individuals who subsequently suffer from acute coronary events. It is unknown whether inflammation modifies this relationship. This population-based study explored the effects of inflammation and hypertension on incidence of coronary event, and on the fatality of the future events. Blood pressure (BP) and five inflammation-s
What is already known about this subject • The occurrence of idiosyncratic drug hepatotoxicity is a major problem in all phases of clinical drug development and the leading cause of postmarketing warnings and withdrawals. • Physical exercise can result in transient elevations of liver function tests. • There is no consensus in the literature on which forms of exercise may cause changes in liver
Parkinson's disease (PD) is characterized by the formation of intracytoplasmic inclusions, which contain α-synuclein (α-syn) protein. While most profound neurodegeneration is seen in the dopamine (DA) synthesizing neurons located in the ventral midbrain, it is unclear why some DA cell groups are more susceptible than others. In the midbrain, the degeneration of the substantia nigra (SN) DA neurons
To elucidate if an effect of propofol on endothelium-dependent relaxation could contribute to propofol-induced vasodilation, smooth muscle relaxation of isolated human omental artery and vein segments precontracted by endothelin-1 were measured. Substance P induced a concentration-dependent relaxation (mean +/- SEM) in both artery (63 +/-8.4% of precontraction, n = 9) and vein (60+/-11%, n = 7). T
Host-related and environmental factors for tuberculosis have usually been investigated separately using different study designs. Joint investigation of the genetic, immunologic, and environmental factors at play in susceptibility to tuberculosis represents an innovative goal for obtaining a better understanding of the pathogenesis of the disease. In this paper, the authors describe methods being u
Under normal conditions about 50% of the placental venous return bypasses the liver through the ductus venosus. This blood flow is preferentially directed toward the foramen ovale and provides optimum oxygenation to the fetal heart and brain. Absence of the ductus venosus is a rare vascular anomaly, the significance of which has been disputed. We distinguish the pattern in which the liver is entir
dc sputter deposition of stoichiometric Al2O3 is usually difficult due to the formation of an oxidized layer on the target surface, which reduces the deposition rate drastically and causes charge buildup and arcing at the target. To avoid this situation the arrival rate ratio O2/Al must be high enough at the substrate position that a stoichiometric film can form but low enough at the target that a
With a large number of sequenced microbial genomes available, tools for identifying groups or classes of proteins have become increasingly important. Here we present an improved pattern for the identification of cell wall-attached proteins (CWPs), a group of proteins with diverse and important functions in gram-positive bacteria. This tripartite pattern is based on analysis of 65 previously descri
