问个java正则表达式匹配字符串的有关问题，

问个java正则表达式匹配字符串的问题，在线等。
一个字符串是这样的：s=“van Bakel,H., Nislow,C., Blencowe,B.J. and Hughes,T.R. Most ‘‘dark matter’’ transcripts are associated with known genes. PLoS Biol., 8, e1000371.”
我相匹配出这个字符串s1=“Most ‘‘dark matter’’ transcripts are associated with known genes”
s1的前后都不固定，“PLoS Biol”这是某个期刊的名称，开头是都是大写的，我想从s中匹配出s1，请问正则表达式该如何写？

[解决办法]
(?<=T.R. \b).+\b(?=\bPLoS\b)
但是如果前后都不固定 怎么写我也不知道，零宽断言他总得有个对应的表达式啊。其实最简单的便是匹配你的s1，也就是“Most ‘‘dark matter’’ transcripts are associated with known genes” 自然就获得了这个字符串，但是我不明白你到底要做啥。
[解决办法]
for example

Java code

String s="van Bakel,H., Nislow,C., Blencowe,B.J. and Hughes,T.R. Most ‘‘dark matter’’ transcripts are associated with known genes. PLoS Biol., 8, e1000371.";Pattern p = Pattern.compile("(?<=[.]\\s)[A-Z].*?(?=[.]\\s[A-Z])"); //(.空格开始)+大写字母+任意字符+(.空格+大写字母结束)Matcher m = p.matcher(s);while (m.find()) {    System.out.println(m.group());}
