Pancreatic dysfunction in acute pancreatitis

In the normal setting, the release of digestive substances and hormones from the pancreas is closely regulated. However, a variety of diseases, such as acute pancreatitis (AP), may disturb this balance. A limited number of studies on exocrine function in the acute phase of pancreatitis have been performed, most of them in animals. In the convalescent phase of AP, a substantial number of patients w

Instantaneous end moraine and sediment wedge formation during the 1890 glacier surge of Brúarjökull, Iceland

Contemporary understanding of the behaviour of surging glaciers and ice streams is hampered by the lack of data on landsystem evolution and sedimentary environments. This study concerns the ice-marginal environment of the surge-type Brúarjökull in Iceland. The sediment distribution in the glacier forefield as well as the morphology, sedimentology and tectonic architecture of the 1890 end moraine i

Development of reagents for differential protein quantitation by subtractive parent (precursor) ion scanning

We present a generic approach for quantitative differential proteomics that reduces data complexity in proteome analysis by automated selection of peptides for MS/MS analysis according to their isotope-labeling ratio. Isotopic reagents were developed that give products which fragment easily to generate a unique pair of signature ions. Using the ion-pair ratio, we show that it is possible to select

ADL dependence in the elderly population living in the community: the influence of functional limitations and physical environmental demand

Empirical research elucidating the relationships between aspects of functional competence and environmental factors is lacking. This study aimed to analyse how functional limitations in the individual and housing accessibility problems influence ADL dependence in the elderly population, and to test Lawton's docility hypothesis. Data were collected from 133 Swedish subjects aged 75–84, who were liv

Monocyte and Neutrophil Chemotactic Activity at the Site of Interstitial Inflammation in Patients on High-Flux Hemodialysis or Hemodiafiltration

Background/Aims: We have observed a difference between patients on low-flux hemodialysis (HD) or peritoneal dialysis and patients on hemodiafiltration (HDF) or high-flux HD in the capacity of transmigrated leukocytes to mobilize CD11b in response to inflammatory stimuli compared with healthy subjects. This could be due to different interstitial chemokine concentrations. Methods: We measured concen

Metabolic response to temperature variation in the great tit: an interpopulation comparison

1. We studied the resting metabolic rate (MR) from two great tit Parus major (Linnaeus) populations living in different winter regimes. Birds from the two different localities were exposed individually to +25 °C, 0 °C and −10 °C for the night in three consecutive sessions in random order. 2. Birds from Lund (Sweden) had a lower basal MR, as measured at thermoneutrality (+25 °C), than had birds fr

Does nociceptin play a role in pain disorders in man?

Nociceptin-immunoreactive cellbodies were detected in the human trigeminal ganglion, while no such fibers were identified in the temporal artery or in dermal tissue from the neck region. In four healthy subjects receiving nociceptin into the temporal muscle in an open labeled design no pain was detected. In 10 healthy subjects who received 200 pmol of nociceptin into tender non-dominant trapezius

The Unperturbed Oxo-Sulfido Functional Group cis-Mo(VI)OS, Related to that in the Xanthine Oxidase Family of Molybdoenzymes: Synthesis, Structural Characterization and Reactivity Aspects

The oxo-sulfido functional group cis-MoVIOS is essential to the activity of the xanthine oxidase family of enzymes but has proven elusive to synthesis in molecules containing no other four-electron ligands. A direct route to molecules containing this group has been achieved. The reaction system [MoO2(OSiPh3)2]/L in dichloromethane yields the complexes [MoVIO2(OSiPh3)2L] (L = phen (1), Me4phen (2),

Childhood sexual abuse. Women's health when starting in group therapy

Childhood sexual abuse has been shown to be common among adult women, 15-30% in prevalence studies, and among mentally ill women, 25-77%. These women often suffer from depression, anxiety, sexual and relationship problems. Suicide attempts and self-destructive behaviour are common. Within the Department of Psychiatry at Lund University Hospital, 45 women with experiences of childhood sexual abuse

Activation of latent protease function of pro-hK2, but not pro-PSA, involves autoprocessing

BACKGROUND: Human glandular kallikrein 2 (hK2) and prostate-specific antigen (PSA) are members of an extensive kallikrein family of proteases. Both proteases are secreted as zymogens or proenzymes containing a seven amino acid propeptide that must be proteolytically removed for enzymatic activation. The physiological proteases that activate pro-hK2 and pro-PSA are not known. METHODS: The pro-hK2 p

Rapid induction of apoptosis in B-cell lymphoma by functionally isolated human antibodies

Novel panning and screening methodology was devised to isolate high affinity human recombinant scFv antibody fragments with functionally associated properties in B lymphoma cells. The approach was used to generate a panel of apoptosis-inducing antibodies specific for antigens differentially expressed in B lymphoma vs. T leukaemia cells. The selections resulted in an antibody pool with near perfect

Formation of highly hygroscopic soot aerosols upon internal mixing with sulfuric acid vapor

The hygroscopic properties of submicron soot particles during internal mixing with gaseous sulfuric acid have been investigated using a combined tandem differential mobility analyzer (TDMA) and differential mobility analyzer-aerosol particle mass analyzer (DMA-APM) technique. Fresh particles exhibit no change in mobility size and mass at subsaturated conditions, whereas particles exposed to gaseou

Transition probabilities for some spectral lines of N III

Transition probabilities based on sophisticated configuration-interaction wave functions have been obtained for transitions between the 20 lowest lying fine-structure levels of the 2s(2)2p, 2s2p2, 2p3, 2s(2)3s, 2s(2)3p and 2s(2)3d states of N III. The calculations were performed using the CIV3 code of Hibbert, and small empirical adjustments were introduced to the diagonal Hamiltonian matrix eleme

Delay between fusion pore opening and peptide release from large dense-core vesicles in neuroendocrine cells.

Peptidergic neurotransmission is slow compared to that mediated by classical neurotransmitters. We have studied exocytotic membrane fusion and cargo release by simultaneous capacitance measurements and confocal imaging of single secretory vesicles in neuroendocrine cells. Depletion of the readily releasable pool (RRP) correlated with exocytosis of 10%-20% of the docked vesicles. Some remaining ves

Beyond the public and private divide: remapping transnational climate governance in the 21st century

This article provides a first step towards a better theoretical and empirical knowledge of the emerging arena of transnational climate governance. The need for such a re-conceptualization emerges from the increasing relevance of non-state and transnational approaches towards climate change mitigation at a time when the intergovernmental negotiation process has to overcome substantial stalemate and

5-Hydroxytryptamine contracts human uterine artery smooth muscle predominantly via 5-HT2 receptors

Serotonergic receptors were classified in the isolated human uterine artery with intact endothelium, using agonists and antagonists for 5-hydroxytryptamine (5-HT) receptors. The efficacy for different agonists rated: alpha-methyl-5-HT (5-HT2) = 5-HT (non-selective) = 2-methyl-5-HT (5-HT3) >> sumatriptan (5-HT1), and the potency as: sumatriptan = 5-HT > 5-HT > alpha-methyl-5-HT > 2-methyl-5-HT.
