Abstract: A memory management method and system for an Android system, and a storage medium. The Android system includes a framework layer, a native layer and a kernel layer; the memory management system includes a service component on the framework layer, a memory manager on the native layer and an interface reclaimer on the kernel layer; the service component communicates with the memory manager and the interface reclaimer, respectively; the memory manager is configured to determine a memory event based on pressure stall information (PSI) obtained from a hook on a memory reclaim path, and report the memory event to the service component; and the service component is configured to call the interface reclaimer in response to the memory event being an event of reclaiming memory based on a process, and shut down a corresponding process interface by the interface reclaimer.

Abstract: The use of levo-ornidazole in the preparation of medicine for preventing and treating the anti-anaerobic bacteria infection is provided. It is demonstrated that levo-ornidazole exhibits lower toxicity and less central inhibition effects than dextro-ornidazole or racemic ornidazole. L-ornidazole possesses pharmacokinetics characteristics, which are superior to that of the racemic ornidazole, and anti-anaerobic activities which are slightly better than or substantially the same as that of the racemic ornidazole. Also, this invention particularly relates to a preparation process, which comprises formulating L-ornidazole as anti-anaerobic infection pharmaceutical preparations, which are suitable for clinical uses.

Abstract: Processes for the preparation of racemic and optically active nucleoside analogs of formula (A) are described. These compounds are useful as anti-infective agents, antisense therapeutic agents and hybridization assay probes.

Abstract: An optically active N-(?-mercaptopropionyl)glycine, i.e., R-(?)-N-(?-mercaptopropionyl)glycine or S-(?)-N-(?-mercaptopropionyl)glycine, a preparation method thereof, a pharmaceutical preparation containing the compound or a pharmaceutically acceptable salt or ester thereof, and use of the same in preparation of detoxification medicament for improving metabolism, are provided.

Abstract: The use of levo-ornidazole in the preparation of anti-parasitic infection drug is provided. It is demonstrated that levo-ornidazole is superior to dextro-ornidazole and racemic ornidazole in the therapeutic action against parasitization (especially trichomonas vaginalis infection and cecal amoeba infection), and thus it is more practicable to formulate L-ornidazole as anti-parasitic infection drugs, and particularly as drug preparations which are suitable for clinical uses, including oral preparation, intravenous preparation and vaginal preparation.
