Medical material

Bone tissue, a vital component for self-healing. This inherent regenerative capacity enables bones to repair themselves following injury or damage. Understanding the mechanisms behind bone tissue self-healing is of great significance in the field of medical research and has implications for the development of novel therapeutic approaches.

Normally, any ferromagnetic or ferrimagnetic material undergoes a transition to a paramagnetic state above its Curie temperature. Superparamagnetism is different from this standard transition since it occurs below the Curie temperature of the material. Superparamagnetism occurs in nanoparticles which are single domain. This is possible when their diameter is below 3–50 nm, depending on the materials.

Exposure of mammalian cells to oxidant stress causes early (iron catalysed) lysosomal rupture followed by apoptosis or necrosis. Enhanced intracellular production of reactive oxygen species (ROS), presumably of mitochondrial origin, is also observed when cells are exposed to nonoxidant pro-apoptotic agonists of cell death. We hypothesized that ROS generation in this latter case might promote the apoptotic cascade and could arise from effects of released lysosomal materials on mitochondria.

Structural elucidation of the lipopolysaccharide (LPS) from threeserotypef Haemophilus influenzaeclinical isolates RM6255, RM7290and RM6252 has been achieved using NMR spectroscopy techniques and ESI-MS on O-deacyl-ated LPS and core oligosaccharide material (OS) as well as ESI-MS n on permethylated dephosphorylated OS. This is the first study to report structural details on LPS from sero-type f strains.

Structural analysis of the lipopolysaccharide (LPS) from nontypeableHaemophilus influenzaestrain 981 has been achieved using NMRspectroscopy and ESI-MS on O-deacylatedLPSand core oligosaccharide (OS)material as well as by ESI-MS n on permethylated dephosphorylated OS. A heterogeneous glycoform population was identified, resulting from the variable length of the OS branches attached to the glucose residue in the common structural element of H. influenzae LPS, L-a-D-Hepp-(1fi2)-[PEtnfi6]-L-a-D-Hepp-(1fi3)-[b-D-Glcp-(1fi4)]-L-a-D-Hepp-(1fi5)-[PPEtnfi4]-a-Kdop-(2fi6)-Lipid A....

For 30 years, the field of medical device technology has struggled to identify the specifications for optimal biocompatibility. For the vast majority of devices, clinical experience has eventually confirmed that the best performance is achieved when biocom-patibility is equated with biological safety that is materials are selected on the basis of maximizing bioinertness and minimizing toxicity and irritation.

The nano-scale spatial organization of metallic and other inorganic materi-als into 1D objects is a key task in nanotechnology. Nano-scale fibers and tubes are very useful templates for such organization because of their inherent 1D organization. Fibrillar biological molecules and biomolecular assemblies are excellent physical supports on which to organize the inor-ganic material.

In vertebrates, phosphocreatine and ATP are continuously interconverted by the reversible reaction of creatine kinase in accordance with cellular energy needs. Sarcoma tissue and its normal counterpart, creatine-rich skel-etal muscle, are good source materials to study the status of creatine and creatine kinase with the progression of malignancy.

Barnacle attachment to various foreign materials in water is guided by an extracellular multiprotein complex. A 19 kDa cement protein was purified from the Megabalanus rosacement, and its cDNA was cloned and sequenced. The gene was expressed only in the basal portion of the animal, where the histologically identified cement gland is located.

Background: To be useful for genetic display of foreign peptides a viral coat protein must tolerate peptide insertions without major disruption of subunit folding and capsid assembly. The folding of the coat protein of RNA phage MS2 does not normally tolerate insertions in its AB-loop, but an engineered single-chain dimer readily accepts them as long as they are restricted to one of its two halves.
