The present invention provides convergent processes for preparing (−)-beta-elemene, (−)-beta-elemenal, (−)-beta-elemenol, and (−)-beta-elemene fluoride and analogues thereof. Also provided are intermediates useful for preparing (−)-beta-elemene. The present invention further provides novel compositions based on analogues of (−)-beta-elemene, (−)-beta-elemenal, (−)-beta-elemenol, (−)-beta-elemene fluoride and methods for the treatment of cancer, such as brain tumor, lung cancer, breast cancer, prostate cancer, ovarian cancer, colorectal cancer, gastric intestional cancer, and stomach cancer. The inventors propose a combination therapy using 1) one or more of the following anti-cancer agents: including, but not limited to, Cisplatin, 5-FU, Taxol, Taxol derivatives, and any anti-cancer agent, and 2) one or more of the following (−)-beta-elemene and its analogs, including (−)-beta-elemene, (−)-beta-elemenal, (−)-beta-elemenol, (−)-beta-elemene fluoride, and their analogs, and (−)-beta-elemene's intermediate in its chemical synthesis, for the treatment of cancer, especially for the treatment of brain tumor, lung cancer, ovarian cancer, bladder cancer, cervical cancer, colon cancer, breast cancer, and prostate cancer.
摘要:
A BLT can include a different channel length, channel width, or both to compensate for bit line loading effects. The channel length and/or channel width of the transistor structure can be configured so as to achieve a desired loading. Thus, the bit line transistor structure can improve global metal bit line loading uniformity and provide greater uniformity in bit line bias. Additionally, the greater uniformity in bit line bias can improve reliability.

A virtual binding system ensures that the WORM logic for protecting data immutability cannot be circumvented, effectively guaranteeing WORM property of a WORM storage system composed of rewritable magnetic hard disks. To close the security hole between the rewritable media and the WORM logic, virtual binding securely authenticates the legitimacy of a WORM logic controller before granting data access on a WORM storage media. Furthermore, the system verifies the legitimacy of the WORM logic controller during data access. This approach virtually binds together the WORM logic controller and the WORM storage media even though the WORM logic controller and the WORM storage media may be physically separate.

A special-purpose file system is provided which includes a combination of services and features which improve the performance of applications employing caches, such as caching web proxies. This file system also provides a file system cache which can be used as a general high-performance file system cache for file systems which need a cache. The services and features include collocating files together on a disk; keeping file meta-data in memory; compressing file names to hash values for reference; using a flat naming scheme for files; providing background daemons that pack files into clusters and clean disk and main memory space; and implementing a user-level library. The file system reduces access to related disk files, eliminates disk operations that are needed to maintain directory and meta-data information, and avoids multiple buffering of file data, and saves and efficiently manages disk and main memory space.
摘要:
A method, system and apparatus for processing multiple attention levels in an electronic message can include assigning different attention levels to corresponding different designated recipients for a single message. More specifically, the method can include the step of generating separate messages from the single message and specifying a different one of the attention levels for each of the separate messages. Moreover, each of the separate messages can be addressed to be received by recipients which correspond to the specified one of the attention levels. Finally, the separate messages can be forwarded to addressed ones of the designated recipients.

Also provided is a method of mapping protein-protein interactions of protein complexes using various mass spectrometry techniques.
摘要:
A computer start-up timing control device and a method thereof are provided for generating a power supply signal to enable a power supply unit (PSU) to provide power. The device includes a chipset, a delay circuit, and a logic gate. The delay circuit delays a standby power ready signal of the computer to generate a standby power delay signal. The chipset generates a power supply signal. The standby power delay signal enables the logic gate to transmit the power supply signal to the PSU via the logic gate. The PSU provides a power to make the computer enter a start-up procedure. The standby power delay signal delays the time for the chipset to send a power supply signal, so that a baseboard management controller (BMC) has enough time to complete initialization. Therefore, the chipset is prevented from accessing the BMC and obtaining erroneous information before the BMC finishes initialization.
