Effects of body fatness and physical activity on cardiovascular risk: risk prediction using the bioelectrical impedance method.

Aims: To explore the effects of body fat percentage (BF%) on incidence of and mortality from cardiovascular disease (CVD) and to study the cardio-protective effect of physical activity in relation to BF%. Methods: A total of 26,942 men and women, aged 45-73 years, without history of CVD were followed up for incidence of coronary events (CE), ischaemic stroke, and CVD mortality over seven years in

A Swedish study of chemoradiation in squamous cell carcinoma of the esophagus

This multicenter study describes the development of a chemoradiation protocol for the treatment of non-metastatic squamous cell carcinoma of the esophagus. Eighty patients were treated with three courses of chemotherapy (cisplatinum and 5-fluorouracil) with concomitant radiotherapy (40 Gy) during the last two courses of chemotherapy. Esophagectomy was performed, when feasible. If no operation was

Survival of full-thickness retinal xenotransplants without immunosuppression

Background: A study was carried out to explore the survival of xenogeneic full-thickness retinal transplants in the subretinal space of hosts without immunosuppression. Methods: Nine adult rabbits received a complete immature rat neuroretina in the subretinal space. No immunosuppression was given, and the animals were followed up for 15 or 34 days. The eyes were then examined histologically with h

Effects of increased solar ultraviolet-radiation on terrestrial plants

Physiological and developmental processes of plants are affected by UV-B radiation, even by the amount of UV-B in present-day sunlight. Plants also have several mechanisms to ameliorate or repair these effects and may acclimate to a certain extent to increased levels of UV-B. Nevertheless, plant growth can be directly affected by UV-B radiation. Response to UV-B also varies considerably among spec

Extended Producer Responsibility in Cleaner Production: Policy Principle to Promote Environmental Improvements of Product Systems

Popular Abstract in Swedish Produkternas miljöpåverkan har varit en av de stora nya frågorna sedan 10-15 år tillbaka. Att det uppstår betydande miljöproblem under en varas hela livscykel förstod man snart, men frågan var vad man kunde göra åt det. Jag kom att arbeta med återvinningsfrågor under senare hälften av 1980-talet. Det var också vid den tiden som förebyggande miljöskyddsstrategier börjadeThe focus of the environmental policy-making has shifted noticeably during the last decade. From having played a fairly insignificant role in the 1980s and earlier, product-related environmental problems have attracted an ever-increasing interest from policy-makers, especially in industrialised countries in North-Western Europe. Considerable attention has been devoted to the concept of extended pr

Morphine with or without a local anaesthetic for postoperative intrathecal pain treatment after selective dorsal rhizotomy in children

Selective dorsal rhizotomy is a surgical procedure with a selective division of posterior spinal nerve rootlets to treat spasticity in children. The extensive surgical procedure with multilevel laminectomies and the nerve root manipulation result in intense pain postoperatively. Two intrathecal (IT) regimes of pain treatment were compared in these children, concerning their pain relief and possibl

State-centered versus nonstate-driven organic food standardization: A comparison of the US and Sweden

Organic food standardization is an increasingly important strategy for dealing with consumer concerns about the environment, animal welfare, health, and the economic structure of food production. But the ways in which this consumer-oriented strategy is introduced, organized, and debated vary considerably across countries. In Sweden, a nongovernmental organization [KRAV (Association for Control of

Escherichia coli TolA tolerates multiple amino-acid substitutions as revealed by screening randomized variants for membrane integrity and phage receptor function

Escherichia coli TolA is a cytoplasmic membrane protein required for outer membrane integrity and the translocation of F-specific filamentous (Ff) bacteriophage DNA. Both phage infection and membrane integrity depend on several TolA interactions, e.g. those of the TolA C-terminal domain (TolAIII). Membrane integrity involves interaction with two host proteins and phage translocation requires direc

Properties of arrowroot starch treated with aqueous HCl at ambient temperature

Arrowroot starch was acid-treated using 2.2 M HCl at 29 to 30degreesC for durations of 0 to 72 h, and properties of the control and modified samples were compared. Increasing length of acid treatment produced a progressive decline in amylose blue value, intrinsic viscosity, and swelling power, as well as an increase in free sugars and solubility. Differential scanning calorimetry (DSC) studies hig

EMERALD & EMIT – worldwide computer aided education and training packages in medical physics

This paper describes the development of two web based education and training packages EMERALD and EMIT designed to meet the training needs of professional medical physicists. The programme has been developed over a number of years by collaboration between hospitals and universities across Europe. The programme concentrates on assisting competence development in five initial areas; diagnostic radio

Preference among preferences as a method for obtaining a higher ordered metric scale

A method is presented for collecting data which yield a scale on which the entities are ranked in preference and all combinations of value distances are ranked (higher-ordered metric scale). The method is based on the concept of secondary preference, i.e. preference among preferences. This method is compared with a classical method based on 50–50 game comparison. Two empirical studies are presente
