Deviations from classical two-state kinetics in protein folding need not always be explained by the presence of rapidly formed intermediates. In some cases, such deviations are caused by short-lived aggregates whereas in other cases they arise from changes of the position of the transition state. These are two new facets of the mechanism of two-state folding. The first part of this account describ

An instrument with integrated flow injection analysis (FIA) system has been developed for on-line monitoring a process for conversion of biomass under field condition. The instrument consists of a newly designed biosensor for easy renewal of the bio-receptor without disassembling the sensor, a FIA controller for controlling the analysis operations, and a computer-based data acquisition system for

Purified polyclonal immunoglobulin preparations representing the 4 rat IgG subclasses were tested for binding to Staphylococcus aureus protein A attached to 3 different solid phases (Staphylococcus aureus Cowan I bacteria, Sepharose CL4B and Sepharose 6MB). Protein A Sepharose CL4B showed higher reactivity with IgG1 and IgG2b than the staphylococci, whereas protein A Sepharose 6MB showed a lower u

The aim of the present work was to compare natural and chemical gypsums with respect to dehydration rate and to investigate the influence of air temperature, particle size and air humidity. No difference in calcination rate could be observed between natural and FGD-gypsum. However the small samples did not permit tests of setting times or simulation of the mixer behaviour. The calcination rate was

Background. During the past decade, experimental studies have provided convincing evidence that microcirculatory dysfunction plays a pivotal role in the manifestation of tissue injury in ischemia-reperfusion and osteomyocutaneous flap transfer. The study of the mechanisms of injury, however, requires sophisticated experimental in vivo models. With the use of microsurgical techniques, osteomyocutan

Asymmetric vestibular function affects optokinetic after-nystagmus (OKAN) in man, but little is known about the involvement of cervical proprioception in the visual-vestibular interaction reflected as OKAN. We studied the effect of asymmetric cervical proprioception induced by active maximal, or passive 70 degrees sustained horizontal head rotations on OKAN in 16 healthy subjects. We evoked optoki

OBJECTIVE: The study was performed in order to evaluate to what extent hypertension or diabetes mellitus may affect the urinary excretion rate of Tamm-Horsfall protein. MATERIALS AND METHOD: The urinary excretion rates of albumin and Tamm-Horsfall protein, a measure of glomerular and distal tubular function, respectively were measured in patients with essential hypertension (n = 17) and in type 1

Type II collagen (CII) is the main protein component of cartilage and immune recognition of CII plays a critical role for the development of collagen induced arthritis (CIA), a widely used animal model for rheumatoid arthritis (RA). Antigen presentation is an important requirement for the immune response, the more efficient presentation of the antigen the better tolerance will be induced and ther

Invariant NKT cells (iNKT cells) are characterized by a semi-invariant TCR comprising an invariant a-chain paired with beta-chains with limited BV gene usage which are specific for complexes of CD1d and glycolipid Ags like a-galactosylceramide (a-GalCer). iNKT cells can be visualized with a-GalCer-loaded CD1d tetramers, and the binding of mouse CD1d tetramers to mouse as well as to human iNKT cell

An adaptive controller needs supervisoryfunctions in order to function well in an industrial environment.This paper describes these needs, and provides examplesof supervisory functions that presently are used in industrialadaptive controllers. These supervisory functions ensure thatadaptation only is performed when proper excitation is available.Supervisory functions that prohibit adaptation durin

We present a first time-resolved deuterium NMR study on wormlike micelles under shear. For the investigation, a micellar system made of soybean phosphatidylcholine (lecithin), D2O, and cyclohexane was studied in the concentrated regime, in the vicinity of the isotropic/nematic transition but positioned in the equilibrium isotropic phase. The D2O dispersed in the micellar core was used as a probe t
