Stretch of the vascular wall by the intraluminal blood pressure stimulates protein synthesis and contributes to the maintenance of the smooth muscle contractile phenotype. The expression of most smooth muscle specific genes has been shown to be regulated by serum response factor and stimulated by increased actin polymerization. Hence we hypothesized that stretch-induced differentiation is promoted

Cartilage glycosaminoglycan (GAG) synthesis and composition, upon which its structural integrity depends, varies with age, is modified by anabolic and catabolic stimuli, and is regulated by UDP-glucuronate availability. However, how such stimuli, prototypically represented by transforming growth factor-beta1 (TGF-beta1) and IL-1alpha, modify GAG synthesis during aging of normal human articular car

Photoemission spectra recorded near the Ga 3p photothreshold from GaN have been found to contain satellites of the main Ga 3d emission line. The intensity of these satellites resonate at this threshold, and are associated with a 3d(8) state. The correlation energies and binding energies for the satellite multiplet have been measured for the satellite and related Auger transitions. The satellite mu

The complex between calmodulin and the calmodulin-binding portion of smMLCKp has been studied. Electrostatic interactions have been anticipated to be important in this system where a strongly negative protein binds a peptide with high positive charge. Electrostatic interactions were probed by varying the pH in the range from 4 to 11 and by charge deletions in CaM and smMLCKp. The change in net cha

Despite the high sensitivity and relatively high tolerance for contaminants of matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) there is often a need to purify and concentrate the sample solution, especially after in-gel digestion of proteins separated by two-dimensional gel electrophoresis (2-DE). A silicon microextraction chip (SMEC) for sample clean-up

We investigate the competition between the associations of oppositely charged protein-surfactant complexes and oppositely charged surfactant complexes. In all systems examined, the most favorable complexation is the one between the two oppositely charged surfactant ions, despite the strong binding known, for example, dodecyl sulfate, DS-, to lysozyme. Thus, the phase behavior of the catanionic sys

Candida arabinofermentans PYCC 5603(T) and Pichia guilliermondii PYCC 3012 were shown to grow well on L-arabinose, albeit exhibiting distinct features that justify an in-depth comparative study of their respective pentose catabolism. Carbon-13 labeling experiments coupled with in vivo NMR were used to investigate L-arabinose metabolism in these yeasts, thereby complementing recently reported physi

Although operational criteria for remission in schizophrenia have recently been proposed, the association of this definition with broader functional outcome has not yet been established in first-episode patients. The severity criteria for remission consist of a score of mild or less on eight core symptoms of schizophrenia. We applied the severity criteria for remission to a sample of patients with

The term 'specialist contractor' in Sweden refers to all contractors who are involved in the construction process, apart from the general contractor. About 12 organizations from eight groups or trades were selected for interviews and the results of those interested and complying with ISO 9000 was varied with the most common problems for the specialist contractors easily identified.

Ligands usually bind to proteins by displacing water from the binding site. The affinity and kinetics of binding therefore depend on the hydration characteristics of the site. Here, we show that the extreme case of a completely dehydrated free binding site is realized for the large nonpolar binding cavity in bovine beta-lactoglobulin. Because spatially delocalized water molecules may escape detect

Denna artikel, som fokuserar hemhjälp till gamla, uppmärksammar dels omsorgens skiftande uttryck i avlönat arbete, dels den hotbild mot omsorgens förutsättningar som kunde skönjas i organisationsmodeller som började införas redan för ett par decennier sedan. Artikeln baserar sig i huvudsak på ett projekt som dokumenteras i antologin Hemhjälp i Norden (red Marta Szebehely, 2003).

This paper studies three different frequency controllers and their effects on the voltage disturbance ride-through capability of a VSC-HVDC supplied industrial system. The idea of implementing frequency controller is to improve the power quality of industrial plants by slightly decreasing the VSC output voltage frequency since industrial processes are more sensitive to voltage drops than frequency

BACKGROUND: A new pain questionnaire should be simple, be documented to have discriminative function, and be related to previously used questionnaires. METHODS: Word meaning was validated by using bilingual Danish medical students and asking them to translate words taken from the Danish version of the McGill pain questionnaire into English. Evaluative word value was estimated using a visual analog

STUDY OBJECTIVE: To evaluate postoperative breathing patterns with a new monitoring device in patients given bupivacaine-morphine epidural analgesia. DESIGN: Open explorative study. SETTING: Inpatient anesthesia in a university hospital setting. PATIENTS: 15 ASA physical status I and II patients aged 28 to 87 years and scheduled for major abdominal surgery. INTERVENTIONS: All patients underwent ab

The evidence for anthropometric factors influencing breast cancer risk is accumulating, but uncertainties remain concerning the role of fat distribution and potential effect modifiers. We used data from 73,542 premenopausal and 103,344 postmenopausal women from 9 European countries, taking part in the EPIC study. RRs from Cox regression models were calculated, using measured height, weight, BMI an
