Plasma Membrane Potential Oscillations in Insulin Secreting Ins-1 832/13 Cells do not Require Glycolysis and are not Initiated by Fluctuations in Mitochondrial Bioenergetics.

Oscillations in plasma membrane potential play a central role in glucose-induced insulin secretion from pancreatic β-cells and related insulinoma cell lines. We have employed a novel fluorescent plasma membrane potential (ψp) indicator in combination with indicators of cytoplasmic free Ca2+ ([Ca2+]c), mitochondrial membrane potential (ψm), matrix ATP concentration and NAD(P)H fluorescence to inves

Participant Experiences in the Environmental Determinants of Diabetes in the Young Study: Common Reasons for Withdrawing.

Background. To characterize participant reasons for withdrawing from a diabetes focused longitudinal clinical observational trial (TEDDY) during the first three study years. Methods. 8677 children were recruited into the TEDDY study. At participant withdrawal staff recorded any reason parents provided for withdrawal. Reasons were categorized into (1) family characteristics and (2) protocol reasons

Neutrophil-derived matrix metalloproteinase-9 is a potent activator of trypsinogen in acinar cells in acute pancreatitis.

MMPs are generally considered to regulate degradation and remodeling of the ECM. Convincing data also implicate a role for MMPs in inflammatory conditions, such as AP, although the mechanisms are not known. The aim of this study was to define the role of MMPs in regulating activation of trypsinogen and tissue damage in AP, which was induced by infusion of taurocholate into the pancreatic duct in m

A Pharmacokinetic and Dosing Study of Intravenous Insulin-Like Growth Factor-I and IGF-Binding Protein-3 Complex to Preterm Infants.

In preterm infants, low levels of Insulin like growth factor 1 (IGF-I) have been associated with impaired growth and retinopathy of prematurity. Our objective was to study safety and pharmacokinetics of intravenously administered rhIGF-I with its binding protein 3 (rhIGFBP-3) to preterm infants. At 3 days chronological age, an intravenous 3 hours infusion of rhIGF-I/rhIGFBP-3 was administered foll

Prophylaxis in von Willebrand disease.

This paper reviews current issues regarding short-term (i.e. for surgery and invasive procedures) and long-term (i.e. regular infusions to prevent bleeding on a permanent or temporary basis) prophylaxis treatment using replacement concentrates for patients with von Willebrand disease (VWD) who do not respond satisfactorily to desmopressin. The standard treatment of these patients is with factor co

Meta-managing: A Study on How Superiors and Subordinates Manage Their Relationship in Everyday Work

In virtually every organization we find formally appointed managers, but nevertheless we tend to condemn the idea of formal hierarchy and celebrate alternative modes of governance that better respect the discretion of employees. This tension, that seemingly surrounds the vertical dimension of contemporary organizations, forms the backdrop of this study which examines how superiors and subordinates

Tehnology Shift and Long term Growth in Regions

Abstract The overarching aim of this paper is to investigate the importance of technological shifts and national macroeconomic preconditions for long term growth and structural transformation in various regions in a national regional system. Intrinsic to this, the issue and origin of divergence and convergence coming in repetitive waves in regional systems will be discussed as a possible contribut

Treatment delay and prognosis in invasive bladder cancer.

Purpose: We studied treatment delay, and the impact on disease specific survival and stage progression in a series of patients who had undergone cystectomy. Materials and Methods: All 141 patients underwent radical cystectomy between 1990 and 1997 due to locally advanced bladder cancer. Treatment delay was defined as time from pathological confirmation of invasive disease to performance of cystect

Cerebral white matter lesions - associations with Aβ isoforms and amyloid PET.

Small vessel disease (SVD) and amyloid deposition may promote each other, with a potential association between SVD and altered production or clearance of β-amyloid (Aβ) affecting its cleavage products. We investigated the relationship between SVD, multiple isoforms of Aβ in cerebrospinal fluid (CSF) and cortical Aβ in 831 subjects with cognitive performance ranging from normal to Alzheimer's disea

The "beta-clasp" model of apolipoprotein A-I - A lipid-free solution structure determined by electron paramagnetic resonance spectroscopy.

Apolipoprotein A-I (apoA-I) is the major protein component of high density lipoproteins (HDL) and plays a central role in cholesterol metabolism. The lipid-free/lipid-poor form of apoA-I is the preferred substrate for the ATP-binding cassette transporter A1 (ABCA1). The interaction of apoA-I with ABCA1 leads to the formation of cholesterol laden high density lipoprotein (HDL) particles, a key step

Neonatal Complications After Maternal Concomitant Use of SSRI and Other Central Nervous System Active Drugs During the Second or Third Trimester of Pregnancy.

Drugs acting on the central nervous system (CNS) and given to a pregnant woman during the latter part of pregnancy may affect neonatal morbidity of the infant. Little is known on the combined effects of different categories of such drugs. The redeeming of prescriptions for CNS-active drugs during the second or third trimester of pregnancy was studied by linkage between a register of prescribed dru

C-peptide in dried blood spots.

Abstract The aim was to evaluate if the Dried Blood Spot (DBS)-technique can be used to analyse C-peptide. S-C-peptide and paired whole blood clotted on filters, dried, punched out and eluted were sampled from 198 healthy subjects. Six subjects with S-C-peptide values outside the reference range were excluded. A conversion formula using log-DBS-C-peptide was generated in a subset of 156 ( approxim
