摘要:
The present invention provides antifungal and antibacterial peptides, especially antifungal peptides obtained from insect species, particularly lepidopterans. The present invention also provides methods of using these antifungal peptides to treat or prevent fungal growth for a variety of purposes such as; protecting plants from fungal infections, treating fungal infections of animals, especially humans, and prevention of food spoilage. In particular, the invention provides transgenic plants that produce an antifungal peptide, said plants having increased resistance to fungal infections/growth.
摘要:
This invention relates to biocompatible, biodegradable thermoplastic polyurethane or polyurethane/ureas comprising isocyanate, polyol and a conventional chain extender and/or a chain extender having a hydrolysable linking group and their use in tissue engineering and repair applications, particularly as stents and stent coating.
摘要:
The present invention provides a biocompatible polymer composition for use in biomedical applications comprising a base molecule, a linker molecule and at least one initiator compound, said base molecule having at least two differing functionalities, and said linker molecule having a functionality reactive with at least one functionality of said base molecule, the first of said at least two functionalities of said base molecule enabling a first curing stage of said polymer composition by reaction with said linker molecule, and the second and any further functionality of said base molecule enabling second and further curing stages of said polymer composition, said first, second and any further curing stages being capable of activation simultaneously or independently of each other as required. The invention further provides uses of the polymer compositions of the invention in biomedical applications such as tissue engineering, dry delivery, as a bioadhesive in wound healing, as bone substitutes or scaffolds, as cements in dental and periodontal applications and as anti-adhesives or protective barriers.
摘要:
The present invention relates a method of generating modified binding moieties comprising a cytokine binding domain consisting of a first FnIII-like domain and a second FnIII-like domain in which at least one amino acid residue within the cytokine binding domain in modified such that the binding characteristics of the cytokine binding domain are altered, and/or, the solubility and/or stability of the binding moiety is improved. The invention also relates to binding moieties and to the use of such binding moieties as affinity reagents, diagnostic reagents, therapeutic agents and protein scaffolds.
摘要:
A detection system for use in an aircraft which is able to monitor atmospheric conditions ahead of the aircraft, generate an alarm signal if adverse atmospheric conditions exist ahead of the aircraft and generate information which indicates the position of the adverse conditions so the adverse conditions can be avoided. The system is able to detect the presence of volcanic ash cloud ahead of the aircraft and, if desired, can also be used to detect a high density of sulphur dioxide gas and/or clear air turbulence ahead of the aircraft. The system monitors infrared radiation received by the aircraft, generates intensity signals representative of at least one predetermined wavelength of the radiation and compares intensity signals with reference signals or intensity signals of another infrared wavelength. If the results of the comparison which indicate the adverse conditions are present, an adverse condition warning signal is generated and the device is also able to generate video display signals for producing a video display which indicates the position of the adverse conditions relative to the aircraft.
摘要:
A head washing apparatus has a head support (20) which supports the animal head (15) so that the muzzle is directed upwardly. A plurality of nozzles (16, 17) direct water under pressure in a plurality of directions onto the animal head (15) so that water is directed into upwardly opening orifices (18). Head turning means (30) turns the head support (20) in increments relative to the nozzles (16, 17) so that water is directed onto the head (15) and into the orifices (18) by the nozzles while the head is in different orientations relative to the nozzles (16, 17). Conveyor means (24) conveys the head support (20) to and from the head washing station. The nozzles (16, 17) are mounted by a carriage (50) which tracks the movement of the head (15).
摘要:
A process for the production of lower molecular weight polymers by free radical polymerization, characterized in that there is added to the polymerization system a compound of general formula (I), wherein R is hydrogen, chlorine, an alkyl group, or a group capable of activating the vinylic carbon towards free radical addition; R is hydrogen or an optionally substituted alkyl, alkenyl, aryl, cycloalkenyl or cycloalkyl group or the group -COZ, where Z is R or OR , where R is hydrogen or an optionally substituted alkyl, alkenyl or aryl group. X is a hydrogen atom, an alkyl or aryl group, or a halogen, and the two X groups may be the same or different. The invention also includes polymers or oligomers made by the process and novel compounds of general formula (I) as defined above.
