A procedure for guaranteed cost control design of delayed linear bilateral teleoperation systems with nonlinear external forces is proposed. The assumption that the external forces are nonlinear functions of velocities and/or positions of local devices, and one part of these forces satisfies a sector condition has been made. A virtual tool system is introduced to 'observe' the forces at the remote

An association between tumor-specific HMG-CoA reductase (HMGCR) expression and good prognosis has previously been demonstrated in breast and ovarian cancer. In this study, the expression, clinicopathological correlates and prognostic value of HMGCR expression in colorectal cancer was examined.

A fundamental role of the innate immune system is to elicit a proper response against both invading pathogens and tissue damage or danger signals. Although the innate immune system often is successful in eliminating danger, an excessive host-response can result in severe tissue injury. Factors that contribute to the elimination of the microbe are the same factors that cause tissue injury. Therefor

Reference attributed grammars (RAGs) extend Knuth’s attribute grammars with references. These references can be used to extend the abstract syntax tree to a graph. We investigate how RAGs can be used for implementing tools for visual languages. Programs in those languages can often be expressed as graphs.

Two new galloylated flavonoid glycosides, quercetin-3-O-(3 ''-O-galloyl)-beta-glucopyranoside (1) and quercetin-3-O-(3 ''-O-galloyl)-beta-galactopyranoside (2) were isolated from the aerial parts of Geranium stepporum along with the four known flavonoids, quercetin 3-O-beta-glucopyranoside (3), quercetin 3-O-beta-galactopyranoside (4), quercetin 3-O-(6 ''-O-galloyl)-beta-glucopyrinoside (5) and qu

P>Benchmarking and comparisons between transplantation centers are becoming more common. A crude comparison indicated a 50% difference in patient survival between centers in Sweden. A 'task group' was formed to refute or confirm and learn from this observation. Patient survival and graft survival of 5 933 patients transplanted at three different transplantation centers in Sweden (Stockholm, Gotebo

Objective. The aim of the study was to determine the effect of -ketoglutarate on the blood lipid profile using a rat animal model with experimentally induced hypercholesterolaemia. Material and methods. The female and male (30/30) Wistar rats had ad libitum access to a diet containing cholesterol (1 %) and lard (10 %) throughout the entire experimental period (120 days). On day 60 of the study, bo

The ongoing and planned experimental activities with direct reference to light unflavoured pseudoscalar mesons motivate a new theoretical study regarding their properties. An overview including details on new precise calculations is presented.

Psychiatric and metabolic features appear several years before motor disturbances in the neurodegenerative Huntington's disease (HD), caused by an expanded CAG repeat in the huntingtin (HTT) gene. Although the mechanisms leading to these aspects are unknown, dysfunction in the hypothalamus, a brain region controlling emotion and metabolism, has been suggested. A direct link between the expression

This is a study about fairly ordinary situations in elder care: how staff deal with older people’s influence, how staff talk about older people’s complaints, how family members talk about elder mistreatment, and how older people act in order to exert influence in a nursing home. However ordinary, these are situations where relational power is accentuated, accomplished and able to be empirically ex

Therapeutic vaccination targeting self-molecules is an attractive alternative to monoclonal antibody-based therapies for cancer and various inflammatory diseases. However, development of cancer vaccines targeting self-molecules has proven difficult. One complicating factor is that tumor cells have developed strategies to escape recognition by the immune system. Antigens specifically expressed by t

OBJECTIVE-A genome-wide association study (GWAS) in Pima Indians (n = 413) identified variation in the ataxin-2 binding protein 1 gene (A2BP1) that was associated with percent body fat. On the basis of this association and the obese phenotype of ataxin-2 knockout mice, A2BP1 was genetically and functionally analyzed to assess its potential role in human obesity.
