摘要:
A distributor device for use in aluminium casting includes a rigid, substantially bowl-shaped receptacle (2) of a refractory material having a base member (4) and a peripheral wall (6) that extends upwards from the base. The receptacle has an inlet opening (8) towards the upper end thereof and a pair of outlet openings (14) towards the base thereof. The device is constructed and arranged such that, in use, molten aluminium poured into the distributor device through the inlet opening (8) is redirected by the distributor device and flows outwards into the mould through the outlet openings (14).

A continuous casting installation includes a furnace (2) for heating metal to a first liquid metal temperature, a degassing unit (4), a filter (6), a heating unit (8) and a casting machine (10). The casting machine (10) includes a pair of casting rollers and a nozzle arranged to deliver liquid metal into a nip between the casting rollers, such that the metal solidifies as it passes through the nip. The heating unit (8) is located between the furnace and the casting machine, and is thermostatically controlled to heat the liquid metal to a second liquid metal temperature.
摘要:
Effective combinations of antisense oligonucleotides directed against thymidylate synthase mRNA are provided for use in cancer therapies. Combinations of antisense oligonucleotides have enhanced activity compared to the activity of the individual antisense oligonucleotides when used alone. The combinations may be used in conjunction with one or more chemotherapeutic agents to enhance the effects of the chemotherapeutic(s). Such antisense oligonucleotide combinations constitute improved antisense therapies with application to a variety of cancers or proliferative disorders, including drug resistant cancers.
摘要:
The present invention provides antisense oligonucleotides useful for identifying drug targets for cancer therapies and for enhancing current cancer therapies. The oligonucleotides of the invention are complementary to thymidylate synthase mRNA and affect expression of at least one other gene. For the enhancement of cancer therapies, such antisense oligonucleotides can be used in conjunction with standard chemotherapeutic agents in order to target thymidylate synthase, as well as other appropriate targets. The antisense oligonucleotides and the methods of the invention constitute improved antisense therapies with application to a variety of cancers.
摘要:
Antisene oligonucleotides targeted to sequences in thymidylate synthase (TS) mRNA. In particular the invention relates to antisense oligonucleotides targeted to sequences in the 3′ end of TS mRNA, which are both cytostatic on their own when administered to human tumour cell lines, and which also enhance the toxicity of anticancer drugs such as Tomudex. The invention also relates to antisense oligonucleotides targeted to sequences at or near the translation start site at the 5′ end of TS mRNA which induce TS gene transcription and enhance cell growth. The invention further relates to a combination product comprising an antisense oligonucleotide in combination with an anticancer agent such as Tomudex (N-(5[N-3,4-dihydro-2-methyl-4-oxoquinazolin-6-ylmethyl)-N-methylamino]-2-thenoyl)-L-glutamic acid) or the Zeneca development compound ZD 9331 ((S)-2-(2-fluoro-4-[N-(4-hydroxy-2,7-dimethylquinazolin-6-ylmethyl)-N-(prop-2-ynyl)amino] benzamido-4-(1H-1,2,3,4-tetrazol-5-yl) butyric acid), and to the use of such a combination product in the treatment of cancer.
