Epidermal growth factor (EGF) is a mitogenic stimulus in many tissues and occurs in large amounts in the pancreas and salivary glands. Whether EGF is mitogenic in the pancreas is controversial, and the EGF effect has not been studied in the salivary glands. Therefore, the aim of the present study was to investigate the possible effects on the pancreas and parotid and submandibular glands at differ

Abnormalities of micturition occur in many different diseases, have a variety of causes and take several forms. This review will focus exclusively on those abnormalities in which antidiuretic therapy may be of benefit. These conditions are primarily characterized by an increase in the total amount of urine produced (polyuria) or a circadian shift in the control of urine production and/or voiding (

Lipase-mediated acrylation is an attractive alternative to more traditional chemical processes, since it provides specific catalysis under mild conditions. A detailed study of the effects of solvent choice and substrate concentrations on the acrylation of octanol by Candida antarctica lipase B (Novozyme(R) 435) is presented. Acrylic acid was found to have a pronounced inhibitory effect. Partial ne

We report electron paramagnetic resonance (EPR) studies on photosystem II (PSII) from higher plants in five different domains of the thylakoid membrane prepared by sonication and two-phase partitioning. The domains studied were the grana core, the entire grana stack, the grana margins, the stroma lamellae and the purified stromal fraction, Y100. The electron transport properties of both donor and

Delayed hydride cracking (DHC) velocity was determined at 203,227,250 and 283 degrees C using 17 mm width curved compact toughness specimens machined from an unirradiated Zr-2.5 wt.% Nb pressure tube spool, gaseously charged with 60 ppm of hydrogen by weight. Single CT specimen was used to determine DHC velocity at a constant temperature for a range of stress intensity factor (K-1) obtained by loa

We have investigated the dissolution of a natural oxide layer on a Nb(110) surface upon heating, combining x-ray reflectivity, grazing incidence diffuse scattering, and core-level spectroscopy. The natural oxide reduces after heating to 145 degrees C partially from Nb2O5 to NbO2, and an enrichment in subsurface interstitial oxygen by similar to 70% in a depth of 100 A is observed. After heating to

Background The yeast Malassezia is considered to be one of the factors that can contribute to atopic dermatitis (AD). Objectives To investigate the reactivity to Malassezia allergens, measured as specific serum IgE, positive skin prick test and positive atopy patch test (APT), in adult patients with AD. Methods In total, 132 adult patients with AD, 14 with seborrhoeic dermatitis (SD) and 33 heal

There is a growing interest within the Wastewater Treatment Plant (WWTP) modelling community to correctly describe physico-chemical processes after many years of mainly focusing on biokinetics. Indeed, future modelling needs, such as a plant-wide phosphorus (P) description, require a major, but unavoidable, additional degree of complexity when representing cationic/anionic behaviour in Activated S

PURPOSE: To assess cardiac mortality, coronary artery disease, myocardial dysfunction, and valvular heart disease in women younger than 65 years of age, at least 10 years after adjuvant radiotherapy following mastectomy in early breast cancer. METHODS AND MATERIALS: Ninety women (45-64 years old) with Stage II breast cancer without relapse, included in the South Sweden Breast Cancer Trial (premeno

A train of attosecond pulses, synchronized to an infrared (IR) laser field, is used to create a series of electron wave packets (EWPs) that are below the ionization threshold in .helium. The ionization probability is found to strongly oscillate with the delay between the IR and attosecond fields twice per IR laser cycle. Calculations that reproduce the experimental results demonstrate that this io

Objective To evaluate the use of continuous amplitude-integrated EEG (aEEG) as a prognostic tool for survival and neurological outcome in cardiac arrest patients treated with hypothermia. Design Prospective, observational study. Setting Multidisciplinary intensive care unit in a university hospital. Intervention Comatose survivors of cardiac arrest were treated with induced hypothermia for 24 h. A

Ecological corridors are frequently suggested to increase connectivity in fragmented landscapes even though the empirical evidence for this is still limited. Here, we studied whether corridors, in the form of linear grass strips promote the dispersal of three grassland butterflies, using mark-recapture technique in an agricultural landscape in southern Sweden. We found no effects of the presence o

Over the years, pervaporation has been widely investigated as a technique for separation of liquid mixtures and recovery of organic compounds from diluted solutions. So far, the research has focused on applications in wastewater treatment, in pharmaceutical industry, for removing the products from fermentation broth in bioreactors and for aroma recovery. When it comes to pervaporation of aroma com

This paper treats implementation of on-line procedures forautomatic performance monitoring. Two on-line detectionprocedures, one that detects oscillations in control loopsand one that detects sluggish control loops, are first summarized.The implementation aspects of these procedures are then discussedand experiences of their use in various industrial products aredemonstrated.

In mammals, the increase in gene dosage, in the form of polyploidy or involving chromosomal fragments, has deleterious effects [1]. Regulation of appropriate gene product amounts has to be warranted by complex dosage-compensation mechanisms. Lower vertebrates, on the other hand, cope very well with ploidy increase [2 4], implying either effective compensation or a lack of necessity for such mechan

To investigate the possibility of simplifying electrocardiogram (ECG) recording in children, we compared waveforms in conventional 12-lead ECGs to those derived from EASI leads in 221 children of various ages. The conventional 12-lead ECGs and the ECGs using EASI electrode positions were collected simultaneously. We developed and determined the value of age-specific transformation coefficients for
