- Rat liver fructose-1,6-diphosphatase was phosphorylated with (32P)ATP and the catalytic subunit of cyclic AMP-dependent protein kinase from pig muscle. After digestion with pepsin, α-chymotrypsin and subtilisin a peptide with the amino-terminal sequence Ser-Arg-Tyr-(32P)SerP-Leu-Pro-Leu-Pro was isolated. A synthetic unphosphorylated heptapeptide with the same amino acid sequence, ending with leucine, was phosphorylated with an apparent Km of 400 μM, while the apparent Km value for fructose-1,6-diphosphatase was 30 μM (subunit concentration). The Vmax value was 20 times higher for the peptide than for the enzyme.

Why should physicians read?
- 2010

Doktorsavhandling (övrigt vetenskapligt)abstract
- Is literary experience of any practical relevance to the clinician? This is the overall question addressed by this investigation, which starts by tracing the historical roots of scientific medicine. These are found to be intimately linked to a form of rationality associated with the scientific revolution of the 17th century and with “modernity”. Medical practice, however, is dependent also on another form of rationality associated with what Stephen Toulmin calls “the epistemology of the biographical”. The very core of clinical medicine is shown to be the clinical encounter, an interpretive meeting where the illness experience is at the centre of attention. The physician can reach the goals of medicine only by developing clinical judgement. Clinical judgement is subjected to close analysis and is assumed to be intimately connected to the form of knowledge Aristotle called phronesis.In order to explore how literature – drama, novels, poetry – may be related to clinical judgement, a view of literature is presented that emphasizes literature as an invitation to the reader, to be met responsibly and responsively. Literature carries a potential for a widened experience, for a more nuanced perception of reality – and this potential is suggested to be ethically relevant to the practice of medicine. The “narrative rationality” of a literary text constitutes a complement to the rationality pervading scientific medicine.The final step in my analysis is a closer exploration of the potential of the literary text to contribute to the growth of clinical judgement, in relation to the challenges of everyday clinical work. Some of the conditions that may facilitate such growth are outlined, but it is also shown that full empirical evidence for the beneficial effects of reading on the clinician reader is beyond reach.

- BackgroundInternet-delivered cognitive behavior therapy (ICBT) for major depression has been tested in several trials, but only with follow-ups up to 1.5 years.AimThe aim of this study was to evaluate the outcome of ICBT 3.5 years after treatment completion.MethodsA total of 88 people with major depression were randomized to either guided self-help or e-mail therapy in the original trial. One-third was initially on a waiting-list. Treatment was provided for eight weeks and in this report long-term follow-up data were collected. Also included were data from post-treatment and six-month follow-up. A total of 58% (51/88) completed the 3.5-year follow-up. Analyses were performed using a random effects repeated measures piecewise growth model to estimate trajectory shape over time and account for missing data.ResultsResults showed continued lowered scores on the Beck Depression Inventory (BDI). No differences were found between the treatment conditions. A large proportion of participants (55%) had sought and received additional treatments in the follow-up period. A majority (56.9%) of participants had a BDI score lower than 10 at the 3.5-year follow-up.ConclusionsPeople with mild to moderate major depression may benefit from ICBT 3.5-years after treatment completion.

Vascular structure and binomial statistics for response modeling in radiosurgery of cerebral arteriovenous malformations

- Radiation treatment of arteriovenous malformations (AVMs) has a slow and progressive vaso-occlusive effect. Some studies suggested the possible role of vascular structure in this process. A detailed biomathematical model has been used, where the morphological, biophysical and hemodynamic characteristics of intracranial AVM vessels are faithfully reproduced. The effect of radiation on plexiform and fistulous AVM nidus vessels was simulated using this theoretical model. The similarities between vascular and electrical networks were used to construct this biomathematical AVM model and provide an accurate rendering of transnidal and intranidal hemodynamics. The response of different vessels to radiation and their obliteration probability as a function of different angiostructures were simulated and total obliteration was defined as the probability of obliteration of all possible vascular pathways. The dose response of the whole AVM is observed to depend on the vascular structure of the intra-nidus AVM. Furthermore, a plexiform AVM appears to be more prone to obliteration compared with an AVM of the same size but having more arteriovenous fistulas. Finally, a binomial model was introduced, which considers the number of crucial vessels and is able to predict the dose response behavior of AVMs with a complex vascular structure.

- AIM: To investigate whether professional training and/or clinical experience affect the ability of caregiver to assess clinical signs of pre-emptive morphine analgesia. METHODS: In the Neurological Outcomes & Pre-emptive Analgesia In Neonates trial preterm infants undergoing mechanical ventilation were randomized to receive continuous infusion, either of morphine or placebo blinded. Staff from centres in Sweden (Stockholm and Orebro) completed an assessment form. RESULTS: A total of 360 assessment forms were collected from 52 neonates. In 59% of the cases, caregivers correctly identified patients group. Comparable proportion of answers were correct between physicians, nurses and assistant nurses (63, 60 and 54%, respectively, p = 0.60). Staff with Neonatal intensive care unit experience <1 year identified 63%, as compared to 65% for working 1-5 year, and 55% that has been working >5 years (p = 0.28). Staff's ability to correctly identify group assignment was reduced by amount of additional morphine (p < 0.01) and severity of illness (p = 0.01). CONCLUSIONS: Clinical medical staffs, including neonatologists, have great difficulties in assessing the presence and severity of pain. Further studies should focus on the methods for assessment of prolonged pain in preterm neonates, define the effects of adequate analgesia, and investigate the clinical factors that may alter neonatal responses to acute and prolonged pain.
