Common infections may cause memory decline

exposure to common infections is linked to memory and brain function - even if the infections never made you ill, a new research has warned.
Researchers found an index of antibody levels caused by exposure to Chlamydia pneumoniae, Helicobacter pylori, cytomegalovirus, and herpes simplex viruses 1 and 2 was associated with worse cognitive performance, including memory, speed of mental processing, abstract thinking, planning and reasoning ability.
"We were very interested in what were the risk factors for cognitive performance and decline," said Clinton Wright, the study's lead researcher and scientific director of the Evelyn F McKnight Brain Institute at the University of Miami.
Earlier studies have already linked certain infections to an increased risk of stroke and Alzheimer's disease.
Researchers investigated if evidence of past exposure to these infections contributed to performance on tests of memory, thinking speed and other brain functions.

Infosphere DATASTAGE 9.1 Features

IBM DATASTAGE 9.1 Training and Important Features

Datastage 9.1 accompanies an unstructured content stage that makes Excel simpler to read regardless of the fact that it is not a culminated organized table.  Datastage can go in and discover section headings if they are on line 1 or column 10.  It can parse the sections and transform them into social information and even extra additional content strings, for example, a solitary remark field.  Datastage 9.1 can conquer a great deal of the issues you get from Excel as a source when individuals refuse around with the spreadsheet form. 

Quicker Database Writes 

 Datastage 9.1 is quicker when keeping in touch with Db2 and Oracle on account of enhanced enormous buffering of information. Prophet Bulk Load and Db2 Bulk Load are quicker.  Oracle Upsert is speedier.  The Connector stages are better. 

Quicker Netezza Table Copies 

 IBM presents another interface called Data Click - it guarantees to load tables from a source Oracle or Db2 table into Netezza with only two clicks.  Two clicks!  The new comfort will immediately produce the Datastage employment needed to move the tables chose into Netezza.  Great for quick Poc or coordinated BI advancement.  It can rehash the information development later or immediately create Infosphere CDC table memberships to stay up with the latest progressively. 

Ilog returns to Datastage 

 Many a year back there was a Jrules plugin for Datastage so you could run the ilog Jrule motor in stream with a Datastage work.  IBM has carried this to Datastage 9.1 Parallel Jobs.  What this methods for Datastage is one of the best administers motors available will be accessible to ETL handling.  What it implies for ilog is enormous versatility, running ilog on a matrix or group of Datastage parallel servers with programmed dividing.  It additionally implies ilog can read and compose information in ANY organization - Datastage can read any database, level record, mainframe index, Infosphere CDC membership, SOA message or several other information arrangements and keep in touch with or read from ilog Jrules. 

Second Generation Java Stage 

 In the as good as ever Java Stage for Datastage you will have the ability to view and skim java classes and access a tremendous extent of information sources or targets.  Better access to web requisitions and web information and simpler combination of Java code. 

Keep in touch with Multiple Files 

 Datastage 9.1 makes it less demanding to take an information stream and keep in touch with it to a cluster of yield documents, for example, part information up by client. 

New Expressions 

 A couple old Server Edition works at long last go onto the Parallel canvas -, for example, the famous Ereplace capacity for trading values in content strings. 

Workload Management 

 The Datastage Operations Console, the web provision presented in Datastage 8.7, has another tab for workload administration.  Included in the clusters of goodies is the capacity to top the amount of occupations running immediately, the measure of CPU being utilized and the measure of RAM being utilized by parallel employments.  This might as well keep away from issues you get when you pass 100% RAM usage and amaze the begin up of many concurrent employment demands.  There is additionally the capacity to make queues and apply workload necessities to those queues. 

What Datastage 9.1 Does Not Have 

 It is with some bafflement that I report that the accompanying oft asked for characteristics won't be in Datastage 9.1: Datastage won't have a plugin that slashes products of the soil.  It won't be conceivable to hack up a whole soup in three seconds utilizing parallel slash o-matics.  I'm anxious we will keep on choping utilizing the antiquated strategies. 

 Datastage 9.1 National Language Support gives you a chance to process information in diverse character sets, for example, Mandarin and Japanese.  Unfortunately still no backing for Klingon and it is still not conceivable to process client notions on Twitter that are composed in Klingon, which as we all know has a much wealthier tongue for affront.
