Biochemistry, sometimes called biological chemistry, is the study of chemical processes within and relating to living organisms. Biochemical processes give rise to the complexity of life. A sub-discipline of both biology and chemistry, biochemistry can be divided in three fields; molecular genetics, protein science and metabolism. Over the last decades of the 20th century, biochemistry has through these three disciplines become successful at explaining living processes. Almost all areas of the life sciences are being uncovered and developed by biochemical methodology and research. Biochemistry focuses on understanding how biological molecules give rise to the processes that occur within living cells and between cells, which in turn relates greatly to the study and understanding of tissues, organs, and organism structure and function.

Production of Bispecific Antibodies

Bispecific antibodies comprising (a) a first light-heavy chain pair having specificity for a first target and a sufficient number of substitutions in its heavy chain constant domain with respect to a corresponding wild-type antibody of the same isotype to significantly reduce the formation of first heavy chain-first heavy chain dimers and (b) a second light-heavy chain pair comprising a heavy chain having a sequence that is complementary to the sequence of the first pair heavy chain sequence with respect to the formation of intramolecular ionic interactions, wherein the first pair or second pair comprises a substitution in the light chain and complementary substitution in the heavy chain that reduces the ability of the light chain to interact with the heavy chain of the other light chain-heavy chain pair are provided. Methods of producing such antibodies in one or more cells also are provided.

Device and method for inhibiting release of pro-inflammatory mediator

Stimulation of one or more neurons of the sympathetic nervous system, including the splenic nerve, to attenuate an immune response, including an inflammatory immune response, is discussed. Devices and systems to stimulate the sympathetic nervous system to attenuate an immune response are also discussed. Devices discussed include pulse generators and drug pumps. Systems are described as optionally having one or more sensors and operator instructions. In specific examples, stimulation of the splenic nerve of pigs with a pulse generator is shown to be safe and effective in attenuating a lipopolysaccharide-induced immune response.

Pyrazole compounds useful as protein kinase inhibitors

This invention describes novel pyrazole compounds of formula IIIa: wherein R1 is T-Ring D, wherein Ring D is a 5-7 membered monocyclic ring or 8-10 membered bicyclic ring selected from aryl, heteroaryl, heterocyclyl or carbocyclyl; Rx, Ry, R2; and R2′ are as described in the specification. The compounds are useful as protein kinase inhibitors, especially as inhibitors of Aurora-2 and GSK-3, for treating diseases such as cancer, diabetes and Alzheimer's disease.

Compartmentalised screening by microfluidic control

The invention describes a method for the identification of compounds which bind to a target component of a biochemical system or modulate the activity of the target, comprising the steps of: a) compartmentalising the compounds into microcapsules together with the target, such that only a subset of the repertoire is represented in multiple copies in any one microcapsule; and b) identifying the compound which binds to or modulates the activity of the target; wherein at least one step is performed under microfluidic control. The invention enables the screening of large repertoires of molecules which can serve as leads for drug development.

Particulate acellular tissue matrix

A method of processing an acellular tissue matrix to give a particulate acellular tissue matrix includes: cutting sheets of dry acellular tissue matrix into strips; cryofracturing the dry acellular tissue matrix strips at cryogenic temperatures; separating the resulting particles by size at cryogenic temperatures; and freeze drying the fraction of particles desired size to remove any moisture that may have been absorbed to give a dry particulate acellular tissue matrix. Rehydration of the dry particulate acellular tissue matrix may take place just prior to use. The particulate acellular tissue may be applied to a recipient site, by way of injection, spraying, layering, packing, in-casing or combinations thereof. The particulate acellular tissue may further include growth and stimulating agents selected from epidermal growth factor, fibroblast growth factor, nerve growth factor, keratinocyte growth factor, platelet derived growth factor, vasoactive intestinal peptide, stem cell factor, bone morphogetic proteins, chondrocyte growth factor and combinations thereof. Other pharmaceutically active compounds may be combined with the rehydrated particulate material including: analgesic drugs; hemostatic drugs; antibiotic drugs; local anesthetics and the like to enhance the acceptance of the implanted particulate material. The particulate material product may also be combined with stem cells selected from mesenchymal stem cells, epidermal stem cells, cartilage stem cells, hematopoietic stem cells and combinations thereof.
