Effects of degraded optical conditions on behavioural responses to alarm cues in a freshwater fish.

Prey organisms often use multiple sensory cues to gain reliable information about imminent predation threat. In this study we test if a freshwater fish increases the reliance on supplementary cues when the reliability of the primary cue is reduced. Fish commonly use vision to evaluate predation threat, but may also use chemical cues from predators or injured conspecifics. Environmental changes, su

Subsequent cancers in patients diagnosed with cancer of unknown primary (CUP): etiological insights?

BACKGROUND: Patterns of subsequent malignancies in patients with cancer of unknown primary (CUP) may provide etiological insight into the primary tumor. The objective of the present study is to quantify risks of the subsequent cancers in CUP patients since such studies are lacking. PATIENTS AND METHODS: A population-based cohort of CUP was identified from the Swedish Family-Cancer Database of year

Molecular characterization of the immune system: emergence of proteins, processes, and domains.

Many genes and proteins are required to carry out the processes of innate and adaptive immunity. For many studies, including systems biology, it is necessary to have a clear and comprehensive definition of the immune system, including the genes and proteins that take part in immunological processes. We have identified and cataloged a large portion of the human immunology-related genes, which we ca

Stoppa plågsamma gudstjänstförsök! Om liturgireformer

The twentieth century was a century of liturgical reforms. Every century has spent great resources on the liturgy, but hardly any other century has spent so much effort on changing it as the twentieth. Yet no-one seems content with what has been achieved. Five motives for liturgical reform are discussed: repristination, active participation, pastoral adaptation, ecumenical convergence, and the sim

Classification of motor commands using a modified self-organising feature map.

In this paper, a control system for an advanced prosthesis is proposed and has been investigated in two different biological systems: (1) the spinal withdrawal reflex system of a rat and (2) voluntary movements in two human males: one normal subject and one subject with a traumatic hand amputation. The small-animal system was used as a model system to test different processing methods for the pros

University training of senior fire brigade officers. The new approach in Sweden

In Sweden a fundamental development has recently taken place in the training of future senior fire brigade officers. There are two main changes: the training period has been substantially increased and the theoretical part upgraded to university curriculum level with final requirements corresponding to a university undergraduate degree. The new educational system reflects the changing and expandin
