High-concurrency database access method and method applied to multi-server system

The invention discloses a high-concurrency database access method. The high-concurrency database access method is characterized in that a trigger is installed in a database; a cache is installed outside the database; when the database is read, the cache is read firstly; and when the database is written, updating data are written into an updating data table and the cache through the trigger. The high-concurrency database access method has the advantages that a caching technology is applied to access and processing procedures of the database, and recently accessed data blocks are stored in the cache generally by the caching technology by the aid of an LRU (least recently used) algorithm; and since core operations of database applications are data access and data processing, if most of the data blocks which are accessed by an application system are already stored in the cache, namely data are hit in the cache, disk I / O (input / output) waiting and bottlenecks applied to data access can be eliminated, and disk data access efficiency and database access efficiency can be optimized maximumly to close to speed of memory access.

Fibrosis-limiting material attachment

Defibrillator lead designs and methods for improved attachment strength between a fibrosis-limiting material covering, a shocking coil electrode, and an implantable lead body are disclosed herein. In certain examples, a portion of the fibrosis-limiting material extends proximal or distal to a shocking coil end and is disposed between a first and a second lead component. In certain examples, a length of compression tubing is utilized. A chronically implanted lead is often encapsulated by a body's fibrotic reaction, which in turn causes future lead explantation to be exceedingly difficult. To reduce fibrotic entanglement, the fibrosis-limiting material covering surrounds strategic portions of the lead. Improving the attachment between the fibrosis-limiting material covering, the shocking coil electrode, and the lead body will allow for improved performance, durability, and extractability of the lead. This disclosure describes several defibrillator lead designs and methods to create these improved joints.

Extractability and Bioavailability of the Natural Antioxidant Astaxanthin From a Green Alga, Haematococcus Pluvialis

As the richest source of astaxanthin, a natural antioxidant and coloring agent, the unicellular green alga, Haematococcus pluvialis, is being commercially exploited. A major constraint in the Haematococcus production system, however, is the thick, rigid cell walls associated with astaxanthin-rich cysts (or aplanospores). The thick walls prevent the extraction of cellular materials and consequently reduce the bioavailability of astaxanthin. Using a physical, chemical, or enzymatic method to disrupt the cell wall has proven to be very expensive and also introduce the risk of oxidation of astaxanthin by atmospheric oxygen The present invention provides a novel method for solving this problem by introducing two genetically modified Haematococcus pluvialis mutants. These two mutants, named as D 13-17 and N54-22, contain remarkably reduced amounts of cell wall materials, but retain the growth potential and ability to accumulate astaxanthin as high as the wild type strain. Organic solvent extraction efficiency assay has demonstrated that cellular astaxanthin can be more effectively and efficiently extracted from the cell wall-deficient mutants than from the wild type, suggesting that the mutants may provide better bioavailability of astaxanthin to humans and animals. The said mutants can be used for production of natural astaxanthin for human and animal consumption
