Lipid oxidation is a major problem in muscle foods, leading to a loss in quality and nutritional value. It occurs in raw meat but is usually more pronounced in cooked meat. Since the demands of consumers for ready-to-eat foods have increased, the control of off-flavour in cooked meat is an important industrial problem. One way of minimising the development of lipid oxidation is to optimise the act
The electron structure of several highly charged ions, belonging to the Mg, Ne, Mn, Fe, Co, Ga and Ge isoelectronic sequences, has been experimentally studied by means of two techniques, beam-foil spectroscopy, BFS, and the spectroscopy of laser-produced plasmas, LPP. The investigations were carried out at Lund University, LU, in 1989-90 and at the China Institute of Atomic Energy, CIAE, Beijing,
The Object Management Group (OMG) has presented a framework for model driven development: Model Driven Architecture (MDA). The departure point of this paper is an interest in process oriented modeling techniques relevant for a computer independent model in the MDA. We searched for the answer on the question what constitutes a “good” computer independent model (CIM). To get an answer we were using
The impact of pH coupled to process design for the conversion of the energy crop Arundo donax to ethanol was assessed in the present study under industrially relevant solids loadings. Two main process strategies were investigated, i.e. the traditional simultaneous saccharification and co-fermentation (SSCF) and a HYBRID design, where a long high temperature enzymatic hydrolysis step was carried ou
Popular Abstract in Swedish Kisel (Si) förekommer i alla naturliga vatten i form av löst kisel och är ett näringsämne för många växt- och djurarter. Löst kisel kommer ursprungligen från kiselhaltiga mineral som har vittrat. Vid vittringen går det åt koldioxid (CO2) och på så vis finns det ett samband mellan omsättningen av kisel och kol. Både upptag och vittring av kisel bidrar till att fördelningSilicon (Si) is ubiqutious in natural waters as dissolved silica (DSi) and is used as a nutrient by many plant and animal species. DSi ultimately derives from the weathering of silicate minerals, a process which also consumes atmospheric CO2 and couples the silicon and carbon cycles. These processes, among others, impart observable fractionations to the stable isotopes of silicon, which makes the
Background: Ghrelin, an endogenous ligand for the growth hormone secretagogue receptor (GHSR), has two major functions: the stimulation of the growth hormone production and the stimulation of food intake. Accumulating evidence also indicates a role of ghrelin in cancer development. Methods: We conducted a case-control study to examine the association of common genetic variants in the genes coding
Objectives: To investigate the effect of prolonged neutralisation of tumour necrosis factor alpha (TNFalpha) on the radiological course in rheumatoid arthritis (RA). To assess whether the radiological course can be predicted by clinical variables or biological markers of cartilage and synovium turnover and of endothelial activation. Patients and methods: Forty seven patients with active RA enrolle
It is of central interest in membrane proteomics to establish methods that combine efficient solubilization with enrichment of proteins and intact protein complexes. We have investigated the quantitative and qualitative solubilization efficiency of five commercially available detergents using mitochondria from the yeast Saccharomyces cerevisiae as model system. Combining the zwitterionic detergent
A terpyridine ligand has been covalently linked to a Ru(bpy)(3) complex via an amide bond. By using this functionalized terpyridine ligand, a series of multinuclear bimetallic complexes have been synthesized and characterized. One of these complexes has the structure of di-mu-oxobridged Mn dimer. EPR spectra of this complex showed that, depending on the procedure for the preparation, the oxidation
Molecularly imprinted polymers (MIPs) are being increasingly used as selective adsorbents in different analytical applications. To satisfy the different application purposes, MEN with well controlled physical forms in different size ranges are highly desirable. For examples, MIP nanoparticles are very suitable to be used to develop binding assays and for microfluidic separations, whereas MIP beads
This study investigated the rationale of boron neutron capture therapy (BNCT) for the treatment of Grade III and IV astrocytoma. The European Community joint research program on BNCT plans to use sulfhydryl boron hydride (BSH) in clinical trials. The work presented here, examines the performance of BSH in eight patients with Grade III and IV astrocytoma using a measurement technique which precisel
Genetically engineered mice have successfully been used to investigate molecular and cellular mechanisms associated with cell dysfunction following brain trauma. Such animals may also offer a possibility to investigate mechanisms involved in posttraumatic hemodynamic alterations. The objective of the study was to establish a mouse model in which important hemodynamic alterations following trauma c
Escherichia coli TolA is a cytoplasmic membrane protein required for outer membrane integrity and the translocation of F-specific filamentous (Ff) bacteriophage DNA. Both phage infection and membrane integrity depend on several TolA interactions, e.g. those of the TolA C-terminal domain (TolAIII). Membrane integrity involves interaction with two host proteins and phage translocation requires direc
Background— Bone morphogenetic proteins (BMPs) are multifunctional proteins that regulate the proliferation, differentiation, and migration of a large variety of cell types. Like other members of the transforming growth factor-ß family, BMPs elicit their cellular effects through activating specific combinations of type I and type II serine/threonine kinase receptors and their downstream effector p
