DESIGN: Cross-sectional study. SETTING: University-based rehabilitation center. PARTICIPANTS: Tai Chi practitioners (n=24; age+/-SD, 68.5+/-6.6 y) and control subjects (n=20; age, 71.3+/-6.7 y) were recruited. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Measures included the following: (1) subjects' intentional weight shifting to 8 different spatial positions within their base of support

Glucose metabolism is subjected to diurnal variation, which might be mediated by alterations in the transcription pattern of clock genes and regulated by hormonal factors, as has been demonstrated for insulin. However, whether also glucagon is involved in the diurnal variation of glucose homeostasis is not known. We therefore examined glucagon secretion after meal ingestion (meal tolerance test) a

The equation , whereH is Heaviside's step function, appears for example in continuous sedimentation of solid particles in a liquid, in two-phase flow, in traffic-flow analysis and in ion etching. The discontinuity of the flux function atx=0 causes a discontinuity of a solution, which is not uniquely determined by the initial data. The equation can be written as a triangular 2×2 non-strictly hyperb

The membrane lipid glucosylceramide (GlcCer) is continuously formed and degraded. Cells express two GlcCer-degrading β-glucosidases, GBA and GBA2, located in and outside the lysosome, respectively. Here we demonstrate that through transglucosylation both GBA and GBA2 are able to catalyze in vitro the transfer of glucosyl-moieties from GlcCer to cholesterol, and vice versa. Furthermore, the natural

OBJECTIVE: The tyrosine kinase receptor Axl is expressed in the vasculature and Gas6 is the ligand. The extracellular part of Axl (sAxl) can be found in circulation. The aim of this study was to determine plasma concentrations of Gas6 and sAxl in patients with abdominal aortic aneurysms (AAA) and to evaluate if Gas6 and sAxl can be used as biomarkers. DESIGN AND METHODS: Immunoassays for sAxl and

The Medtronic Resting Heart System (RHS) is a heparin-coated, closed perfusion circuit. Clinical results indicate less haemodilution and reduced complement activation, when compared with a traditional circuit leading to fewer postoperative blood transfusions. We evaluated the potential clinical benefits, including reduced transfusion requirements, when using the RHS compared with conventional card

A major phytoplankton change occurred during the late 1930s and early 1940s in Koljö Fjord, a sill fjord on the Swedish west coast. Dinoflagellate cyst concentrations increased tenfold over a short period of time, from hundreds of cysts per gram sediment to thousands; and the species composition of both dinoflagellate cysts and diatoms changed markedly. These changes took place during a period of

Abstract in UndeterminedThe hitherto most successful theory explaining why similar industrialized market economies have developed such varying systems for social protection is the Power Resource Theory (PRT), according to which the generosity of the welfare state is a function of working class mobilization. In this paper, we argue that there is an under-theorized link in the micro-foundations for

Background: Nurse assistants working in residential care facilities need support to ensure that they provide high-quality care for the residents and support for relatives, from admission to bereavement. Aim. The aim was to describe the nurse assistants' experience of how an intervention with a palliative care approach, had influenced them in their work in residential care for older people. Parti

AIM: The aim of this study was to evaluate wound healing, major amputation and mortality in patients with diabetic foot ulcer and peripheral arterial disease (PAD), and to compare the group decided to have an endovascular intervention with groups referred to conservative treatment or to those judged as unreconstructable. METHODS: A retrospective two-year review of all patients with diabetic foot

This paper aims to provide a basis for renewed talk about “use” in computing. Four current “discourse arenas” are described. Different intentions manifest in each arena are linked to failures in ”translation,” different terminologies crossing disciplinary and national boundaries non-reflexively. Analysis of transnational use discourse dynamics shows much miscommunication. Conflicts like that betwe

To estimate the impacts of future climate change on streamflow in the Tangwang River basin (TRB) in northeastern China, 2 hydrological models, the Soil and Water Assessment Tool and the Hydro-Informatic Modeling System, were used. These models are driven by future (2021-2050) local rainfall and temperature scenarios downscaled from global climate model (GCM) simulations from the fifth phase of the

BACKGROUND: The medical programme at Lund University, Sweden, has undergone curricular reform over several stages, which is still ongoing. Students have been somewhat negative in their evaluations of the education during this time. AIM: To find out how the students perceived the educational climate using the Dundee Ready Education Environment Measure (DREEM), and to compare the findings taken at t

Pseudomyogenic hemangioendothelioma (PMH) is a well-recognized neoplasm that usually arises in the soft tissue; concurrent bone involvement occurs in 24% of cases. PMH of bone without soft tissue involvement is rare. We describe the clinicopathologic findings of 10 such cases, the largest series reported to date. The study included 9 male and 1 female patient; their ages ranged from 12 to 74 years
