距離上次 World Community Grid 啟動的新專案 – Help Fight Childhood Cancer 不久，前幾天收到 World Community Grid 寄來的信，最近開始了一個新的 Research Project
- Influenza Antiviral Drug Search，顧名思義，就是要研發對抗流感的藥物，主要針對那些已經對一般藥物產生抗藥性的強大流感病毒。
如果你不想讓你的 CPU 繼續吃閒飯，那麼可以藉由這個機會加入這個人類對抗病毒的大戰！！
Title: World Community Grid - You Can Help Fight Influenza!
World Community Grid has started a new research project that will use your donated computer time to find new drugs that can stop the spread of an influenza infection in an individual. The research will specifically address the influenza strains that have become drug resistant, as well as new strains that are appearing. Your computer will help identify the chemical compounds that are the best candidates. This will accelerate the efforts to develop treatments that would be useful in managing seasonal influenza outbreaks and future influenza epidemics.

The mission of the Influenza Antiviral Drug Search project is to find new drugs that can stop the spread of an influenza infection in the body. The research will specifically address the influenza strains that have become drug resistant as well as new strains that are appearing. Identifying the chemical compounds that are the best candidates will accelerate the efforts to develop treatments that would be useful in managing seasonal influenza outbreaks, and future influenza epidemics and even pandemics.
Hundreds of thousands of people around the world die each year as a result of influenza infections. If a particularly virulent strain emerges that is readily transmitted among humans, a pandemic can potentially kill millions of people. The influenza virus mutates rapidly and therefore new varieties of influenza appear each year. Influenza vaccines are designed to anticipate the strains likely to be prevalent for the next flu season but can often miss newly evolved varieties. While drugs such as oseltamivir (commercial name Tamiflu) and zanamivir (commercial name Relenza) help keep influenza from spreading in the body, they do not work for all types of influenza and new drug resistant forms of influenza evolve and cannot be treated with these drugs. When drug resistant strains emerge, manufacturers designing vaccines may not be able to respond quickly enough to prevent a large outbreak of the disease. This project will search for promising new drug leads that stop the replication of the influenza viruses within the body, potentially helping patients who are not immune to a particular form of influenza. The discovery of both broad-spectrum and specific antiviral drugs is expected to significantly improve global health.
One promising approach to combat these viruses and prevent them from causing disease is to develop new drugs that inhibit neuraminidase (N1, N2, etc), NS1 protein, hemagglutinin, and possibly other targets that influenza needs to spread in the body. Using the known chemical structures of these target molecules, the project will perform virtual chemistry experiments and determine which of millions of known compounds attach to these target molecules in a manner that can disable or inhibit them, thus potentially keeping the influenza virus from spreading in the body. These experiments are performed using a program called AutoDock, from the Scripps Research Institute. This software is used for several other projects on World Community Grid. These include FightAIDS@Home, Discovering Dengue Drugs - Together, and Help Fight Childhood Cancer projects. Once drug candidates are identified using World Community Grid, then additional laboratory work, testing and ultimately drug trials will be required. This will likely not lead to any immediate treatments for influenza during the current H1N1 outbreak. However, influenza viruses cause recurrent seasonal disease outbreaks and have the potential for evolving into dangerous forms. Thus, proceeding on this project at this time will give us a better chance to be prepared for more serious outbreaks in the future.
In an effort to spread the words about WCG, I will include a link to my last post about WCG – here it is: Help Fight Childhood Cancer
最近因為工作關係，遇到要用 Google Form 及 Google Sheet 所以研究了 Google Sheet 裡的一些 function 怎麼用 首先，分享一下如何在 Google Sheet 裡用規則運算 :D
今天坎尼去上課老師講了一題很有趣的題目 所以回到家坎尼就順手試驗了一下 I. XOR (exclusive OR) XOR 是邏輯運算子之一，定義為： 當兩數的值不同才為 true，相同則為 false 其他相關說明可以參考 維基百科：XOR II. 程式 以往的做法會宣...
今天測試了從 phpMyAdmin 介面將 MySQL DB 中的中文資料匯出成 .csv 檔，原本想說既然中文資料可以正確以 utf-8 編碼存入 MySQL，在 phpMyAdmin 的網頁介面上也可以正常顯示，之前匯出成 .sql 檔也沒有亂碼問題，那匯出 .csv 這種...
雖然到最後你還是沒留下你的名字... 今天就來介紹一下，如何用程式撰寫多維 矩陣乘法運算 首先要了解一下矩陣乘法的計算方式 (m1 x n1) * (m2 x n2) 結果會是 (m1 x n2)的矩陣 上例中的 n1 = m2 矩陣乘法位置互換結果就會不同 (大家可以直接點上方...
