We recently demonstrated that the LKB1 tumour suppressor kinase, in complex with the pseudokinase STRAD and the scaffolding protein MO25, phosphorylates and activates AMP-activated protein kinase (AMPK). A total of 12 human kinases (NUAK1, NUAK2, BRSK1, BRSK2, QIK, QSK, SIK, MARK1, MARK2, MARK3, MARK4 and MELK) are related to AMPK. Here we demonstrate that LKB1 can phosphorylate the T-loop of all
Objectives. Polyarteritis nodosa (PAN) is a term that has been used to describe a wide variety of vasculitic conditions. In 1994, the Chapel Hill Consensus Conference on the nomenclature of systemic vasculitides proposed that the name classical PAN should be restricted to diseases where there is arteritis in small and medium-sized arteries without the involvement of smaller vessels. Our aim was to
The effects of ATP and histamine on cell proliferation and intracellular calcium concentrations ([Ca2+]i) were examined in the human ovarian cancer cell line SKOV-3. Micromolar concentrations of ATP induced a biphasic increase in [Ca2+]i representing a rapid rise to a peak level followed by a smaller but more sustained phase. When influx of extracellular calcium was blocked by calcium chelation to
Genetic engineering has been used for fusion of the peptide tag, Trp-Pro-Trp-Pro, on a protein to study the effect on partitioning in aqueous two-phase systems. As target protein for the fusions the cellulase, endoglucanase I (endo-1,4-β-d-glucan-4-glucanohydrolase, EC 3.2.1.4, EGI, Cel7B) of Trichoderma reesei was used. For the first time a glycosylated two-domain enzyme has been utilized for add
Objective To compare the rate of prenatal diagnosis of heart malformations between two policies of screening for heart malformations. Design Randomised controlled trial. Setting Six university hospitals, two district general hospitals. Sample A total of 39 572 unselected pregnancies randomised to either policy. Methods The 12-week policy implied one routine scan at 12 weeks including measurement o
OBJECTIVE: To evaluate the feasibility of monophasic action potential (MAP) mapping using a modified-tip NaviStar catheter in swine and humans. METHODS: MAP mapping was performed using the modified-tip catheter at 71 +/- 21 atrial and 60 +/- 16 ventricular sites in 10 healthy pigs and at 56 ventricular sites in one patient, and using an ordinary Navi-Star catheter at 30 atrial sites in one patient
The authors' intention is to show that there are other criteria when optimising digital filters than minimising the filter order. The final result in the form of minimum silicon area or few machine cycles in a high-speed custom DSP are aims that are important in a custom design process. It is not an axiom that the minimum order of the filter gives the optimum result. Algorithms with trivial coeffi
The tegumental glands of Derocheilocaris typica are tricellular. Their openings are formed by two transformed epidermal cells, each with a microvillar crown. These cells form a cuticular socket housing the tip of the underlying secretory cell. From the outside, the gland openings are seen as,a pit in the cuticle, from the bottom of which a thin cuticular chimney ends with a slit-like pore. The gla
Fractures of the femoral neck, that is, "cervical hip fractures" constitute 53% of all fractures of the proximal femur (hip fractures) according to the Swedish National Hip Fracture Register linked to SAHFE (Standardised Audit of Hip Fractures in Europe). The most reproducible classification system divides cervical hip fractures into undisplaced (33%) and displaced (67%). Hip fractures are common
Total energy use during the life cycle of a building is a growing research field. The embodied energy makes up a considerable part of the total energy use in low energy buildings. Recycling provides the opportunity to reduce the embodied energy by using recycled materials and reusable recyclable materials/components. This paper presents values on embodied energy. energy needed for operation and th
In 1996 DG XII of the European Commission (Research and Development) approved a 3 year project on the fire performance of electrical cables. Within this FIPEC project, a major part of the work involved correlation and mathematical modelling of flame spread and heat release rate in cable installations. The FIPEC project has developed different levels of testing ranging from a small-scale, cone calo
BACKGROUND. Recurrence rates after surgical repair of groin hernia vary between 3% and 20%. One possible reason for recurrent hernias are ipsilateral multiple hernias, which might have been overlooked at the primary operation. METHODS. In the present series 1010 patients with unclear groin pain underwent herniography. RESULTS. A total of 314 patients had hernias, and seventy-one (23%) of these had
Self-assembled InAs/AlAs quantum dots embedded in a resonant tunneling diode device structure are grown by molecular beam epitaxy. Through the selective etching in a C6H8O7 center dot H2O-K3C6H5O7 center dot H2O-H2O2 buffer solution, 310 nm GaAs capping layers are removed and the InAs/AlAs quantum dots are observed by field-emission scanning electron microscopy. It is shown that as-fabricated quan
We propose a method to improve the diagnosis of infection in the paranasal sinuses, distinguishing between mucous and serous cases. The method utilizes a previously published method whereby the viscosity in a sealed container may be measured using an ultrasound Doppler method. As ultrasound propagates in a liquid medium, due to attenuation, the resulting pressure gradient will cause the liquid to
Polyploidization, often accompanied by hybridization, has been of major importance in flowering plant evolution. Here we investigate the importance of these processes for the evolution of the tetraploid crucifer Capsella bursa-pastoris using DNA sequences from two chloroplast loci as well as from three nuclear low-copy genes. The near-absence of variation at the C. bursa-pastoris chloroplast marke
The nuclear equation of state (EOS) is probed from statistical parameters, determined in an excitation function experiment on p + Xe-nat reactions at 200-1400 MeV. Total charge (Z) distributions follow a cascade-[multi]fragmentation-evaporation (CFEM) model well. The caloric curve in regions supposedly dominated by fast processes is compatible with a pure statistical multifragmentation (SMM) proce
