Tec family protein tyrosine kinases have in their N-terminus two domains, The PH domain is followed by Tec homology (TH) domain, which consists of two motifs, The first pattern, Btk motif, is also present in some Pas GAP molecules, C-terminal half of the TH domain, a proline-rich region, has been shown to bind to SH3 domains, Mutations in Bruton's tyrosine kinase (Btk) belonging to the Tec family

Starting out from the rather different views on Ego and Alter formulated by Peirce and Bakhtin, and, more indirectly, by Foucault, the present contribution attempts to characterise the position of these familiar philosophical personages within the framework of cultural semiotics, as it has been adapted in Lund from the models of the Prague and Tartu schools. The resulting model is tried out in a c

In this thesis laser-based measurements of in-cylinder flow and fuel concentrations in two stroke and direct injected four-stroke engines are presented. The major problem with the carburetted two-stroke engine is the short-circuiting of fuel that occurs during the scavenging phase. This leads to large emissions of unburned hydrocarbons. The object of this thesis has been to map the flow behaviour

The pycnoconidia in about 70 cetrarioid species have been investigated. Five main types are recognized: bacillariform, bifusiform, citriform, filiform and sublageniform pycnoconidia. The largest variation is found within the bifusiform and citriform types. The variation and presence of different types within cetrarioid lichens are described and discussed.

Background The relationship between blood pressure levels and decline of cognition has been discussed previously, but little is known about the confounding effect of lifestyle factors, anti hypertensive treatment and disease in the elderly. Objective To examine the association between systolic (SBP) and diastolic (DBP) blood pressure, changes of DBP and SBP and hypertension (HT) on cognitive funct

Objective: To investigate the cerebral circulatory response to superimposed acute hypoxemia in growth-restricted fetuses with established brain-sparing flow (BSF) during basal conditions. Material and methods: 76 term fetuses suspected of growth restriction were exposed to Doppler velocimetry in the umbitical artery (UA) and middle cerebral artery (MCA), and in 38-39 cases also in Galen's vein (GV

BACKGROUND: The laparoscopic approach in antireflux surgery might have an impact on the patient's daily activities and well-being. METHODS: Sixty patients were randomized to laparoscopic or open 360 degrees fundoplication. Data were collected by questionnaires and interviews preoperatively, 1 month and 6 months after operation. RESULTS: Five patients in the laparoscopic group were converted to ope

Mutagenic/carcinogenic heterocyclic amines (HAs) are formed at low levels (ng/g) during heat processing of protein-rich food such as meat and fish. The complex matrix requires effective extraction and purification methods. Blue Chitin columns were used for the extraction of HAs from fried chicken fillets and the samples were analysed with LC-MS. Several HAs were identified at levels ranging from 0

Travel patterns among different socio-economic groups in Sweden are investigated. It is shown that elderly persons, persons with low incomes and women in general do not travel extensively. Middle-aged persons, persons with high incomes and men travel much farther. Cars are the dominant transportation mode for all population groups. Aeroplanes are used mostly by high-income earners and men, while p

In this letter, a novel frequency-multiplication device based on a three-terminal ballistic junction is proposed and demonstrated. A 100 nm-size, three-terminal ballistic junction and a one-dimensional (1-D), lateral-field-effect transistor with trench gate-channel insulation are fabricated from high-electron-mobility GaInAs/InP quantum-well material as a single device. The devices show frequency

This report presents the fifth and last experiment in a longitudinal study of text building behaviour at the Gymnasium level of a Swedish School. The series of experiments concerns natural language production as a means for the establishment of state attractors as well as their geometric space descriptions. The hypothesis tested during three years of instruction and learning is whether the evolvin
