Glucagon was discovered in 1922 as a hyperglycemic factor in the pancreas. During its early history up to 1970, glucagon was shown to increase circulating glucose through stimulating glycogenolysis in the liver. It was also shown to be a constituent of islet non-ß cells and to signal through G protein coupled receptors and cyclic AMP. Furthermore, its chemical characteristics, including amino acid

Secretion of outer membrane vesicles (OMV) is an intriguing phenomenon of Gram-negative bacteria and has been suggested to play a role as virulence factors. The respiratory pathogens Moraxella catarrhalis reside in tonsils adjacent to B cells, and we have previously shown that M. catarrhalis induce a T cell independent B cell response by the immunoglobulin (Ig) D-binding superantigen MID. Here we

The 12-item Short-Form Health Survey (SF-12) is an abbreviated version of the SF-36, one of the most widely used patient-reported health outcome rating scales. Similar to the SF-36, it yields summary scores of physical and mental health (PCS and MCS, respectively). However, SF-36 derived PCS and MCS scores have not been found valid in neurological disorders such as Parkinson's disease (PD). Here w

ABSTRACT. Preterm newborn infants have a high morbidity rate. The most frequently affected organs where free gas is involved are the lungs and intestines. In respiratory distress syndrome, both hyperexpanded and atelectatic (collapsed) areas occur, and in necrotizing enterocolitis, intramural gas may appear in the intestine. Today, these conditions are diagnosed with x-ray radiography. A bed-side,

Scholarly discourses on energy security have developed in response to initially separate policy agendas such as supply of fuels for armies and transportation, uninterrupted provision of electricity, and ensuring market and investment effectiveness. As a result three distinct perspectives on energy security have emerged: the `sovereignty' perspective with its roots in political science; the `robust

The use of bibliometric indicators on individual and national levels has gathered considerable interest in recent years, but the application of bibliometric models for allocating resources at the institutional level has so far gathered less attention. This article studies the implementation of bibliometric measures for allocating resources at Swedish universities. Several models and indicators bas

OBJECTIVES: To examine the association between barriers in the outdoor environment and perceived quality of life (QoL) in old age and to assess whether fear of moving outdoors and unmet physical activity need contribute to this association. DESIGN: Cross-sectional. SETTING: Community and research center. PARTICIPANTS: Five hundred eighty-nine, community-dwelling people aged 75 to 81 took part in f

We show that H/D exchange between H2O and D2O in ultrathin ice films adsorbed on Cu(100) does not occur through autoionization at temperatures below 140 K. The exchange is, however, facile if a proton deficiency is induced in the ice films by having small amounts of OH preadsorbed on the copper surface. The system was studied using surface infrared vibrational spectroscopy with the aid of density

Objective: To investigate how subjective perceptions of everyday occupations, activity level, day centre attendance, social interaction, self-mastery and clinical factors were related to how unemployed people with psychiatric disabilities (PD) envision a future worker role, also controlling for socio-demographic variables. Participants: 175 people with PD; 93 attended a day centre and 82 did not.

The objective of this study was to evaluate the proximal composition, as well as Total Antioxidant Capacity (TAC) and Total Phenols (TPH) in meals that represent a complex food matrix, from different hospitals in Bolivia and Sweden. Protein, fat, ash, dietary fiber and carbohydrate contents were measured in 29 samples: 20 from two Bolivian hospitals and 9 from the university hospital in Lund, Swed

Caveolae are 50-100nm large membrane invaginations that play a role in cellular signaling. The aim of the present study was to assess whether muscarinic M(3) receptors and the K(ATP) channel subunit Kir6.1 are associated with human detrusor caveolae, and to pharmacologically assess the relevance of this organization for contractility. Detrusor strips were dissected and used in ultrastructural, bio

We have determined projected rotational velocities, v sin i, from Magellan/MIKE echelle spectra for a sample of 136 early B-type stars having large Galactocentric distances. The target selection was done independently of their possible membership in clusters, associations or field stars. We subsequently examined the literature and assigned each star as Field, Association, or Cluster. Our v sin i r

BackgroundMany malignancies, including multiple myeloma and its precursor, monoclonal gammopathy of unknown significant, are associated with an elevated risk of thromboembolism. There is limited information on the risk of thrombosis in patients with Waldenstrom macroglobulinemia (WM) and lymphoplasmacytic lymphoma (LPL). ObjectivesTo assess the risk of venous and arterial thrombosis in WM/LPL pati

OBJECTIVES: We examined whether the association between hormone therapy (HT) use and coronary heart disease (CHD) risk differed between women with and without vasomotor symptoms (VMS). STUDY DESIGN: We used data from a Dutch (EPOS) and Swedish (WHILA) population-based sample of 8865 women, aged 46-64 years, and free of CHD, stroke, venous thrombosis/pulmonary embolism or cancer at baseline.
