The aim of the present study was to examine the influence of pregnancy on deterioration of retinopathy in patients with Type 1 diabetes mellitus. Sixty-five pregnant Type 1 diabetic women attending the University Hospital in Lund were studied retrospectively. The degree of retinopathy, and levels of HbA1c and blood pressure 12 months before, during, and 6 months after pregnancy were compared of th
Visits to nest holes by birds other than their owners is a familiar phenomenon for students of breeding biology. In this study, we evaluate that behavior using a transponder reading system. Eighty-five males and females were Fitted with transponders at the end of the incubation period or just after hatching. Nest boxes were fitted with transponder readers from just after hatching until all nestlin
An exploratory study of a train evacuation inside a tunnel was performed in order to study the effects of different train exit configurations on the flow rate of people through the exit. A total of 84 participants in the ages 18–40 years took part in the experiment, which was carried out on two separate days and involved 18 evacuation scenarios. The statistical analysis of the experiment demonstra
We present a high-resolution and independently dated multiproxy lake sediment record from the paleolake at Les Echets in southeastern France that displays synchronous changes in independent limnic and terrestrial ecosystem proxies, in concert with millennial-scale climate oscillations during the last glacial period. Distinct lake-level fluctuations, low lake organic productivity, and open, treeles
Unannounced evacuation experiments in a cinema theatre were analysed. The analysis focused on investigating if people are influenced by others during the initial phase of a fire evacuation. This type of influence is called social influence. Three separate behaviour types were identified and studied and the recognition and pre-movement time was measured. The results suggest that social influence is
Bog sites and wetland settlement during the Mesolithic: research from a bog in central Scania, southern Sweden The bogs Agerods Mosse and Ronneholms Mosse with their total area of 12 km(2), form a north-westerly arm of the Ringsjon Basin of central Scania, in the southernmost part of Sweden. In the 1940s and 1970s excavations of Early Mesolithic sites around and within the bog Agerods Mosse were c
This study focuses on the fruit of the African medlar (Vangueria infausta L., family Rubiaceae). The investigation included the development of an extraction procedure of volatile components from the fruit matrix, a purification step, separation, identification and quantification. Initial experiments showed that some components, especially sugars, degrads during the heating in the GC analysis, prod
Behaviours, viewed by nurses as demanding, performed by patients with severe dementia were investigated during one year of intervention. Supervised implementation of individually planned care and systematic clinical supervision were implemented on one experimental ward (EW) while another ward (CW) served as control. Each ward had 11 patients. At baseline and after 6 and 12 months of intervention s
Aims/hypothesis Children with high-risk type 1 diabetes HLA genotype have increased risk of high relative birthweight (HrBW), while cord blood islet autoantibodies decrease the risk. As gestational infections may affect offspring type 1 diabetes risk, the aims were to test whether: (1) children of mothers reporting gestational infections have increased HrBW; (2) gestational infections explain isle
BACKGROUND: The use of nitrous oxide (N2O) during hemodilution has been questioned. Nitrous oxide reduces the inspired oxygen fraction (F1O2), depresses myocardial function and may reduce cardiac output (CO) and systemic oxygen delivery (DO2SY). The aim of this study was to evaluate the importance of the effects of nitrous oxide on systemic and myocardial circulation and oxygenation during extreme
High quality salmon smolts are essential for aquaculture, enhancement programs and wild populations. However, intensification of aquaculture smolt production and changes in natural habitats can cause sub-optimal environmental conditions, which may result in poor smolt quality. The salmon brain, as the integrator of environmental information, plays a focal role in relaying this information through
BACKGROUND: Treatment with heparin has been reported to interfere with lipid metabolism by release of Lipoprotein Lipase (LPL) into the circulation. The purpose of the present study was to determine the effects on LPL activity by anticoagulants in combination with total parenteral nutrition (TPN) in the rat. In an earlier investigation we could show that TPN, per se, caused a three-fold increase o
OBJECTIVE AND DESIGN: To correlate the changes in periarticular tissue levels of pro-inflammatory cytokines and endothelin-1 (ET-1) to local pathophysiology in rats with antigen-induced arthritis (AIA). MATERIALS: The periarticular soft tissue was excised from sixty-six rats at different stages of AIA. METHODS: The samples were homogenized and the levels of immune like (LI) reactivities were deter
In this prospective study, the 10- and 15-year incidence and course of retinopathy were examined in relation to medical risk indicators from 3.1 +/- 1.9 (mean -/+ SD) years diabetes duration and onwards in 29 adult type 1 diabetic patients treated under routine care. A total of 28 patients were followed for 10 years and 20 patients for 15 years diabetes duration. After 10 years diabetes duration,
Bacterial infections of the respiratory tract contribute to exacerbations and disease progression in chronic obstructive pulmonary disease (COPD). There is also an increased risk of invasive pneumococcal disease in COPD. The underlying mechanisms are not fully understood but include impaired mucociliary clearance and structural remodeling of the airways. In addition, antimicrobial proteins that ar
