摘要:
The invention describes the use of a biomarker pentylfuran to detect bacterial and/or fungal pathogens. Pentylfuran is released from certain pathogens and detected in the headspace gas of an in vitro culture or in the breath sample of a patient. Pentylfuran is particularly useful in the detection of Aspergillusspecies, especially Aspergillus fumigatus which is a pathogen of humans.
摘要:
The invention is directed to parapoxvirus vectors. Specifically provided are orf virus vectors containing exogenous DNA. The exogenous DNA may encode a heterologous peptide or polypeptide of which expression is desired, or may encode an antigen capable of inducing an immune response. The capacity to express antigens make these vectors suitable for use in vaccines.
摘要:
High energy dietary supplements which include fat which is at least partially hydrolysed and in which about 40 % to about 55 % of the total energy of the supplement is provided by the fat. The supplements preferably also include one or more non-toxic emulsifiers. The fat is preferably partially hydrolysed milk fat. The supplements also optionally contain other conventional nutritive components such as a carbohydrate source, a texture modifier, sweeteners and flavouring agents. The supplements may be provided either in liquid, semi-solid or solid form, and are believed to be particularly suitable for consumption by endurance athletes.
摘要:
An apparatus for remote gas sensing comprises a light source, a polarising beam splitter (1), a photodetector, a single polarisation preserving optical fibre (2), a gas cell (5) or a zone through which the gas passes, a quarter-wave plate (6) and a mirror (7). A light beam from the light source passes through the beam splitter (1) and is focused by a lens (3) into the fibre (2) where it travels maintaining its polarisation state. Upon exiting the fibre (2), the light is collimated by a second lens (4) and propagates through the gas cell (5) and the quarter-wave plate (6) in a double pass configuration being retro-reflected by the mirror (7). The light beams is then focused back into the fibre (2) where it propagates with a polarisation state which is perpendicular to that of the forward propagating light. When light emerges from the fibre (2), it is reflected by the beam splitter (1) onto the photodetector.
