Immunologically insulin resistant (IIR) type I diabetic patients possess significantly elevated levels of anti-insulin serum autoantibodies. We investigated whether altered insulin processing by B lymphocytes contributes to this form of insulin resistance. A comparison was made of the 125I-labelled human insulin (HI) peptides processed by Epstein-Barr virus (EBV)-transformed B lymphocytes derived

Chronic autoimmune thrombocytopenic purpura (ATP) is a common hematologic disorder in which platelet-specific autoantibodies bind to platelets and enhance their destruction by the reticuloendothelial system. While there has been considerable investigation of the humoral immune abnormalities in ATP, little work has been performed on the cellular immunoregulatory aspects of this autoimmune disorder.

Natural killer (NK) cell activity was studied in 17 patients with primary chronic idiopathic autoimmune thrombocytopenic purpura (ATP). Fifteen of 17 patients had a significantly reduced NK cytotoxicity against 51chromium labeled K562 target cells (mean LU20% = 18 ± 20 in patients versus 65 = 2 5 in controls, P < 0.001). NK activity was also significantly reduced in all of six patients with second

To study the biochemistry of processing of a soluble protein Ag by an APC, we investigated how 125 I-labeled human insulin (HI) is processed in situ by TA3 mouse hybridoma B cells. Fractionation of TA3 cells into their extracellular, plasma membrane-associated and intracellular compartments coupled with the use of HPLC enabled us to analyze several peptides derived from each compartment. One HI

An Escherichia coli strain transfected with a plasmid containing four linked human proinsulin genes was grown in the presence of 35S and 3H labelled amino acids to gain access to human insulin that was radiolabelled at 19 evenly distributed sites throughout the amino acid sequence. The multi-proinsulin precursor was cleaved at methionine residues with cyanogen bromide, then the individual proinsul

This chapter’s aim is to analyze how the unexpected death of a goalkeeperoriginally from Croatia became relevant for supporters of AllmännaIdrottsklubben (AIK), a Swedish football club. I argue that this particularevent drew the attention of club supporters and influenced them, due to thelarger context in which AIK was rooted.

Background: Periodontal disease is associated with cardiovascular disease (CVD) but it is unknown if periodontal disease severity is associated with asymptomatic carotid plaque. The aim of the current population-based, observational study was to investigate if signs of periodontal disease are associated with the occurrence of carotid plaque and total plaque area (TPA). Methods: The Malmö Offspring

With the advancement of the next generation of cellular systems, flexible mechanisms for Discontinuous Reception (DRX) are needed in order to save energy. 5G will bring heterogeneous packet sizes and traffic types, as well as an increasing need for energy efficiency. The current static DRX mechanism is inadequate to meet these needs. In this paper we exploit channel prediction to develop integer p

Objectives: A single nucleotide polymorphism in the NCF1 gene (NCF1-339, rs201802880), encoding NADPH oxidase type II subunit NCF1/p47phox, reducing production of reactive oxygen species (ROS) is strongly associated with the development of systemic lupus erythematosus (SLE). This study aimed at characterising NCF1-339 effects on neutrophil extracellular trap (NET) formation, type I interferon acti

Purpose – As climate change shocks and stresses increasingly affect urban areas in developingcountries, resilience is imperative for the purposes of preparation, recovery and adaptation. This study aims to investigate demographic characteristics and social networks that influence the household capacity to prepare, recover and adapt when faced with prolonged droughts or erratic rainfall events in M

Objective: A large number of different types of digital innovations for health and medical care have been developed in Sweden under the concept of eHealth. Employees’ interest is of great importance in determining the success of different new digital interventions and technologies. Purpose: In this study, we aimed to elucidate the nurses’ experiences as a first “gatekeeper” in an Internet-based Di

Background and purpose — Targeted delivery of drugs is important to achieve efficient local concentrations and reduce systemic side effects. We hypothesized that locally implanted synthetic hydroxyapatite (HA) particles can act as a recruiting moiety for systemically administered drugs, leading to targeted drug accretion. Methods — Synthetic HA particles were implanted ectopically in a muscle pouc

There is some evidence that housing accessibility, external housing-related control beliefs (HCB) and activities of daily living (ADL) are associated in complex ways; however, these pathways have not been explored in younger old. The aim was to assess the role of external HCB in the relationship between housing accessibility and ADL by applying moderation and mediation models. This was a cross-sec

We explore properties of the class of Békollé–Bonami weights B∞ introduced by the authors in a previous work. Although Békollé–Bonami weights are known to be ill-behaved because they do not satisfy a reverse Hölder property, we prove that when restricting to a class of weights that are “nearly constant on top halves”, one recovers some of the classical properties of Muckenhoupt weights. We also pr

The installation of technical solutions for heat recovery from the ventilation air is a very important step, both with respect to improving the indoor climate and as an energy-saving measure. Ventilation without heat recovery use a substantial part of an entire building's heating use, especially if the building is a low energy building. To realize a large implementation of heat recovery property o

Purpose: The purpose of this paper is to explore and analyse how young people conceptualise online traces of search and what strategies they have for dealing with them. Design/methodology/approach: The topic was investigated through a qualitative and ethnographic approach. Interviews, go-alongs and observations in schools were carried out with nine participants in Sweden. Findings: The findings sh

Globalization has increased in recent decades, resulting in structural changes of production and labor demand. This paper examines how the increased global engagement of firms affects the structure of the workforce. We find that the aggregate distribution of occupations in Sweden has become more skilled between 1997 and 2013. Moreover, firms with a high degree of international orientation have a r

Chronic obstructive pulmonary disease (COPD) is one of the leading causes of death worldwide and there are currently limited treatment options for these patients. The disease is characterized by a reduction in airflow due to chronic bronchitis, as well as airspace enlargement in the distal lung, resulting in a loss of surface area available for gas exchange. At end-stage disease, oxygen therapy an

The development of the intraovarian adrenergic nervous system was investigated in the guinea-pig by use of chemical determination of catecholamines with high performance liquid chromatography (HPLC) and with the formaldehyde-induced fluorescence method for visualization of adrenergic nerves (Falck-Hillarp technique). Ovaries from fetuses (39-40, 45-50, 55-57, 60-63 days of gestation) and young ani

The autonomic nerve supply of the guinea-pig ovary was investigated by a combination of light- and electron microscopy. At the light-microscopic level, adrenergic fibres were identified due to their formaldehyde-induced fluorescence. In addition, the ovary contained acetylcholinesterase-positive fibres. In all parts of the ovary, the adrenergic fibres were most numerous. At the ultrastructural lev
