The influence of abdominal surgery on energy expenditure and working capacity

Popular Abstract in Swedish Sjukgymnaster har behandlat patienter i samband med kirurgisk behandling sedan början på 1900-talet och den dominerande uppgiften har varit att förebygga lungkomplikationer och blodproppar samt att bedöma behovet av vidare rehabilitering efter utskrivning. Den medicinska utvecklingen går emellertid snabbt framåt och sjukgymnasten har en utmanande uppgift i att utveckla The overall aim of this work was to study the influence of surgery on energy expenditure (EE) during working capacity measurements and during walking. In the first study the aim was to investigate whether two different devices were sensitive enough to reveal differences in energy expenditure during treadmill walking, and if the measurements were reproducible. It was shown that an airflow of 42.5

In vivo and in vitro glucose-induced biphasic insulin secretion in the mouse - Pattern and role of cytoplasmic Ca2+ and amplification signals in beta-cells

The mechanisms underlying biphasic insulin secretion have not been completely elucidated. We compared the pattern of plasma insulin changes during hyperglycemic clamps in mice to that of glucose-induced insulin secretion and cytosolic calcium concentration ([Ca2+](c)) changes in perifused mouse islets. Anesthetized mice were infused with glucose to clamp blood glucose at 8.5 (baseline), 11.1, 16.7

Isolation and characterization of proteoglycans from human follicular fluid

Two proteoglycans differing in size and composition were isolated from human follicular fluid. The larger one of high density had a molecular mass of 3.0x10(6) Da, as determined by laser light-scattering, and was substituted with 15-20 chondroitin sulphate (CS) chains (Mr 60000-65000). Half of the CS disaccharides were 6-sulphated, whereas the remaining ones were non-sulphated. Digestion of the CS

Personal names and identity

In all societies, personal names are important as a means for recognizing and distinguishing people. The paper, following Claude Lévi-Strauss’ theories on how people systematize the surrounding world through named categories, focuses on how we use names to gain knowledge about who a person “is”. We base our conclusions on culturally shared knowledge about how specific names are related to gender,

Negotiating with the LDCs: Situation and Context

Bilateral foreign aid negotiations between industrialized and less developed countries; based on conference paper. Characteristic features of foreign aid negotiations, as compared to other types of negotiations between states; influence of factors which are external in relation to the negotiations themselves.

Photoelectron spectroscopy study of Ag/Si(111)root 3X root 3 and the effect of additional Ag adatoms

High-resolution core-level spectroscopy has been applied to the Ag/Si(111)root3xroot3 surface. The Si 2p line shape is found to depend critically on the presence of additional Ag adatoms on the surface. A significant broadening caused by the surplus of Ag atoms could be eliminated by careful annealing. The resulting Si 2p spectra are significantly sharper than any published data for this or other

Arsenic trioxide inhibits neuroblastoma growth in vivo and promotes apoptotic cell death in vitro

Recent clinical studies have shown that inorganic arsenic trioxide (As(2)O(3)) at low concentrations induces complete remission with minimal toxicity in patients with refractory acute promyelocytic leukemia (APL). Preclinical studies suggest that As(2)O(3) induces apoptosis and possibly differentiation in APL cells. Like APL cells, neuroblastoma (NB) cells are thought to be arrested at an early st

Identification of cytogenetic subgroups and karyotypic pathways in transitional cell carcinoma

The clinical course in urinary bladder cancer is difficult or impossible to predict based on conventional disease parameters. It is a reasonable hypothesis that the genetic aberrations acquired by the tumor cells, being instrumental in bringing about the disease in the first place, may also hold the key to more reliable prognostication. However, though 200 transitional cell carcinomas (TCC), the m

Protein-polyelectrolyte cluster formatio and redissolution: A Monte Carlo study

Aqueous solutions of proteins and oppositely charged polyelectrolytes were studied at different polyelectrolyte chain length, ionic strength, and protein-protein interaction potential as a function of the polyelectrolyte concentration. One of the protein models used represented lysozyme in aqueous environment. The model systems were solved by Monte Carlo simulations, and their properties were anal

Monitoring referral and treatment in soft tissue sarcoma: study based on 1,851 patients from the Scandinavian Sarcoma Group Register

This report is based on 1.851 adult patients with soft tissue sarcoma (STS) of the extremities or trunk wall diagnosed between 1986 and 1997 and reported from all tertiary referral centers in Norway and Sweden. The median age at diagnosis was 65 years and the male-to-female ratio was 1.1:1. One third of the tumors were subcutaneous, one third deep, intramuscular and one third deep, extramuscular.

Iron superoxide dismutase from the archaeon Sulfolobus sulfataricus : Analysis of structure and thermostability.

The crystal structure of superoxide dismutase (SOD) from the hyper thermophile Sulfolobus solfataricus has been determined at 2.3 Å resolution by molecular replacement and refined to a crystallographic R-factor of 16.8 % (Rfree 19.8 %). The crystals belong to the space group C2 (a = 76.3 Å, b = 124.3 Å,c = 60.3 Å, β = 128.8°) with two identical monomers in the asymmetric unit. The monomer has a mo

Challenges in implementation of research methodology in community-based occupational therapy: The Housing Enabler Example.

This paper focuses on challenges in implementation of research in community-based occupational therapy practice. Based on a two-year project in a south Swedish municipality aiming at studying implementation of structured assessment procedures in the housing adaptation process, the first purpose is to provide a detailed project description, and the second is to report on first results identifying c

Increased serum cartilage oligomeric matrix protein levels and decreased patellar bone mineral density in patients with chondromalacia patellae.

BACKGROUND: Chondromalacia patellae is a potentially disabling disorder characterised by features of patellar cartilage degradation. OBJECTIVE: To evaluate markers of cartilage and bone turnover in patients with chondromalacia patellae. METHODS: 18 patients with chondromalacia patellae were studied. Serum cartilage oligomeric matrix protein (s-COMP) and bone sialoprotein (s-BSP) levels were measur

In vivo effects of endothelin-2, endothelin-3 and ETA receptor blockade on arterial, venous and capillary functions in cat skeletal muscle

This study describes, in quantitative terms, the effects of endothelin-2 and endothelin-3 on vascular tone (resistance) in large-bore arterial resistance vessels (> 25 microns), small arterioles (< 25 microns) and the veins, as well as on capillary pressure and fluid exchange in cat gastrocnemius muscle in vivo. Infusion of endothelin-2 or endothelin-3 (200-1600 ng kg-1 min-1, i.a.) elicited an in

Albuminuria and associated medical risk factors: a cross-sectional study in 451 type II (noninsulin-dependent) diabetic patients. Part 2

The association between urinary albumin concentration (UAC) in a morning urine sample and medical risk factors was evaluated in a cross-sectional study of 451 type II (noninsulin-dependent) diabetic patients. The following four groups of patients were created according to their urinary albumin levels: A) normal (less than 12.5 mg/L); B) high normal (12.5-30 mg/L); C) microalbuminuria, ie, incipien

Functional analysis of monocarboxylate transporter 8 mutations identified in patients with X-linked psychomotor retardation and elevated serum triiodothyronine

Context: T-3 action in neurons is essential for brain development. Recent evidence indicates that monocarboxylate transporter 8 (MCT8) is important for neuronal T-3 uptake. Hemizygous mutations have been identified in the X-linked MCT8 gene in boys with severe psychomotor retardation and elevated serum T-3 levels. Objective: The objective of this study was to determine the functional consequences
