Oxygen supply to immobilized cells : 2. Studies on a coimmobilized algae-bacteria preparation with in situ oxygen generation

A coimmobilized mixed culture of algae, Chlorella pyrenoidosa, and bacteria, Gluconobacter oxydans, has been studied. The conversion of glycerol to dihydroxyacetone(1,3-dihydroxy-2-propanone), catalysed by the bacteria, was used to indicate the oxygen supply in the immobilized preparation. The oxygen produced by the algae in the coimmobilized preparation was used by the bacteria more effectively t

Oxygen supply to immobilized cells : 1. Oxygen production by immobilized Chlorella pyrenoidosa

Oxygen supply at high cell densities of aerobic organisms is a great problem in immobilized cell preparations. To investigate the possibility of in situ oxygen generation the alga Chlorella pyrenoidosa was immobilized on alginate beads. The conditions for optimal oxygen production were investigated and in long term experiments the preparations were successful for at least 30 days.

Low prevalence of known pathogenic mutations in dominant PD genes : A Swedish multicenter study

Objective: To determine the frequency of mutations known to cause autosomal dominant Parkinson disease (PD) in a series with more than 10% of Sweden's estimated number of PD patients. Methods: The Swedish Parkinson Disease Genetics Network was formed as a national multicenter consortium of clinical researchers who together have access to DNA from a total of 2,206 PD patients; 85.4% were from popul

Divide and rule Cyprus? Decolonisation as process

Instances of decolonisation can be considered processes featuring complicated interactions that are both path-depended and open-ended. This perspective contrasts with reductionist epistemologies, particularly economistic ones. Viewing the decolonisation of Cyprus in processual terms, this article argues that the process at hand was crucially shaped by the colonial strategy of divide-and-rule and t

Boatsmen in Blekinge

A brief historical overview of the relocation of more than 3,000 Finnish boatsmen with families to Blekinge during the reign of Charles XI.

Nationwide study of appendicitis in children

Background: Paediatric surgical care is increasingly being centralized away from low-volume centres, and prehospital delay is considered a risk factor for more complicated appendicitis. The aim of this study was to determine the incidence of paediatric appendicitis in Sweden, and to assess whether distance to the hospital was a risk factor for complicated disease. Methods: A nationwide cohort stud

Availability and organization of difficult airway equipment in Swedish hospitals : A national survey of anaesthesiologists

Background: Airway complications account for almost one third of anaesthesia-related brain damage and death. Immediate access to equipment enabling rescue airway strategies is crucial for successful management of unanticipated difficult airway situations. Methods: We conducted a nationwide survey of Swedish anaesthesiologists to analyse availability and organization of difficult airway trolleys (D

The Socio-Legal Relevance of Artificial Intelligence

This article draws on socio-legal theory in relation to growing concerns over fairness, accountability and transparency of societally applied artificial intelligence (AI) and machine learning. The purpose is to contribute to a broad socio-legal orientation by describing legal and normative challenges posed by applied AI. To do so, the article first analyses a set of problematic cases, e.g. image rThis article draws on socio-legal theory in relation to growing concerns over fairness, accountability and transparency of societally applied artificial intelligence (AI) and machine learning.

Cardiovascular Disease, Diabetes Mellitus, and Hypertension in Lewy Body Disease: A Comparison with Other Dementia Disorders

Background: Research concerning the potential roles of cardiovascular disease (CaVD) and diabetes mellitus (DM) as risk factors for Lewy body disease (LBD) is limited. These disorders are, however, established risk factors for vascular dementia (VaD) and have been proposed as risk factors for Alzheimer’s disease (AD). Objective: The aim of this study was to investigate the prevalence of CaVD and D

Early and advanced stages of Maillard reaction in infant formulas : Analysis of available lysine and carboxymethyl-lysine

Although the literature on the Maillard reaction in infant formulas is extensive, most studies have focused on model systems, and in only a few cases on real food systems. Therefore, the objective of the present study was to determine the status of the Maillard reaction, both the early and advanced phases, in a variety of commercial infant formulas available on the Swedish market.
