Barley bread containing lactic acid improves glucose tolerance at a subsequent meal in healthy men and women.
In the present study, we evaluated whether a low glycemic index (GI) breakfast with lactic acid bread had an effect on glucose tolerance and insulinemia at a subsequent high GI lunch meal. A barley bread containing lactic acid and a reference barley bread were consumed in the morning after an overnight fast in random order by 10 healthy men and women. Four hours after the breakfasts, the subjects
Osteopontin is a downstream effector of the PI3-kinase pathway in melanomas that is inversely correlated with functional PTEN
The tumor suppressor PTEN antagonizes phosphatidylinositol 3-kinase (PI3K), which contributes to tumorigenesis in many cancer types. While PTEN mutations occur in some melanomas, their precise mechanistic consequences have yet to be elucidated. We sought to identify novel downstream effectors of PI3K using a combination of genomic and functional tests. Microarray analysis of 53 melanoma cell lines
Cytostatic drug treatment causes seeding of gene promoter methylation.
Calcium deposition and expression of bone modelling markers in the tympanic membrane following acute otitis media
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 challenge - The future of advanced welfare states in the knowledge economy
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
The prognostic significance in Goodpasture's disease of specificity, titre and affinity of anti-glomerular-basement-membrane antibodies.
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 of congenital esophageal stenosis
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.

Construction of cryptographically important Boolean functions
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.

Localized proton magnetic resonance spectroscopy of a cerebellar tumor in a two-year-old child
Use of aqueous two-phase systems in sample preparation for polymerase chain reaction-based detection of microorganisms
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
Treatment of migraine attacks based on the interaction with the trigemino-cerebrovascular system.
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
The influence of lactic acid formation on the simultaneous saccharification and fermentation (SSF) of softwood to ethanol
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
Fatality of acute coronary events in relation to hypertension and low-grade inflammation: a population-based cohort study.
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
Muscular exercise can cause highly pathological liver function tests in healthy men.
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
Severe dyspnoea on light exercise at high altitude: Unusual presentation of Ebstein's anomaly.
Ventral tegmental area dopamine neurons are resistant to human mutant alpha-synuclein overexpression.
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
Effects of propofol on substance P-induced relaxation in isolated human omental arteries and veins
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
Investigation of environmental and host-related risk factors for tuberculosis in Africa. I. Methodological aspects of a combined design
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
