-The original GMV self-tuner was later extended to provide a general framework which included feedforward compensation and user-chosen polynomials with detuned model-reference, optimal Smith predictor and load-disturbance tailoring objectives. This paper adds similar refinements to the GPC algorithm which are illustrated by a set of simulations. The(More)
The development and elaboration of a conceptualization of existential distress in patients with advanced disease is crucial in order to optimize our clinical response within palliative medicine. Demoralization is one expression of existential distress. Its empirical study will be greatly enhanced by a self-report measure that captures its dimensions and(More)
Photorhabdus is a member of the family Enterobacteriaceae that lives in a mutualistic association with a Heterorhabditis nematode worm. The nematode worm burrows into insect prey and regurgitates Photorhabdus, which goes on to kill the insect. The nematode feeds off the growing bacteria until the insect tissues are exhausted, whereupon they reassociate and(More)
OBJECTIVE Demoralization, as described by Jerome Frank, is experienced as a persistent inability to cope, together with associated feelings of helplessness, hopelessness, meaninglessness, subjective incompetence and diminished self-esteem. It is arguably the main reason people seek psychiatric treatment, yet is a concept largely ignored in psychiatry. The(More)
There is growing evidence that abnormal protein folding or trafficking (protein kinesis) leads to diseases. We have used P-glycoprotein as a model protein to develop strategies to overcome defects in protein kinesis. Misprocessed mutants of the human P-glycoprotein are retained in the endoplasmic reticulum as core-glycosylated biosynthetic intermediates and(More)
BACKGROUND Mixed reports exist about the impact of supportive-expressive group therapy (SEGT) on survival. METHODS From 485 women with advanced breast cancer recruited between 1996-2002, 227 (47%) consented and were randomized within an average 10 months of cancer recurrence in a 2:1 ratio to intervention with 1 year or more of weekly SEGT plus three(More)
In a population-based study of Prader Willi syndrome (PWS), we investigated the relation between genetic subtypes of the syndrome and psychiatric morbidity. Of 25 patients aged 18 years or older, seven (28%) had severe affective disorder with psychotic features, with a mean age of onset of 26 years (SD 5.9). The seven people affected, all aged 28 years or(More)

The presenilin containing gamma-secretase complex is responsible for the regulated intramembraneous proteolysis of the amyloid precursor protein (APP), the Notch receptor, and a multitude of other substrates. gamma-Secretase catalyzes the final step in the generation of Abeta(40) and Abeta(42) peptides from APP. Amyloid beta-peptides (Abeta peptides)(More)
