To date, antegrade intussusception involving a Roux-en-Y reconstruction has been reported only once. We report a case of acute bowel obstruction due to an intussusception involving two Roux-en-Y limbs in a 40-year-old woman with a history of chronic pancreatitis due to pancreas divisum. Four years preceding this event, the patient had undergone a Whipple procedure, and three years prior to that, a Puestow operation. The patient was successfully treated with bowel resection and a side-to-side anastomosis between the most distal aspect of the bowel and the most distal Roux-en-Y reconstruction, which preserved both Roux-en-Y reconstructions.

Beginning in the late 1970’s forest industry timberland gained the eye of financial investors. Diamond International and Crown Zellerbach were early firms that were purchased for the “break-up value” of their timberland. Timberland was perceived as undervalued by investors and made forest industry firms attractive takeover targets. This started a process where forest industry divested of its timberland. Some firms formed separate entities for its timberland base. Acquisitions and mergers became popular in the industry. Some forest industry companies converted to real estate investment trusts, for tax and defensive reasons. Large institutional investors became interested in timberland as means to diversify their portfolios and increase financial performance. Timber management investment organizations developed to manage and procure timberland for these institutional investors. Today little of the forest industry timberland remains with vertically-integrated forest products companies. South Carolina’s forest industry timberland decreased by about 800,000 ha since 1993 (or nearly 90%). This has implications for the state’s timber supply. Forest industry timberlands were some of the most productive and intensively managed forests in the state. We address how forest management might change on this timberland and how long-term timber supply might be impacted in the state.

目前,美国已陷入20世纪30年代经济大崩溃以来最严重的一次金融危机。从房市泡沫破裂、次贷危机、油价与物价上涨、经济衰退到一系列大公司倒闭,一连串的人为因素造成了华尔街哀鸿遍野的败象。那么,是什么原因导致了这次美国金融危机的爆发呢?应《文史哲》杂志的邀约,带着这个问题,利用世界著名建设性后现代思想家,美国著名生态经济学家,中美后现代发展研究院院长柯布博士(***,jr.)参加中央编译局和中美后现代发展研究院在美国克莱蒙举办的"马克思主义与生态文明国际学术研讨会"的宝贵机会,美国《世界文化论坛》报主编樊美筠博士专门采访了柯布博士。在访谈中,柯布博士从建设性后现代主义视角对当前这场金融危机进行了诊断。他精辟地指出,此次金融危机实际上宣告了现代西方经济理论特别是风靡一时的新自由主义经济学的失败,因为它是建立在现代机械哲学和个人主义之上的。他明确预言:"美国作为世界经济中心的日子正在飞快地走向终结。"并向世人发出了预警:"美国在不久的将来会成为危险的敌人",至少"它不会是一个很可靠的朋友"。

A new approach is described for delivering small interfering RNA(siRNA)into cancer cells by noncovalently complexing unmodifi ed siRNA with pristine single-walled carbon nanotubes(SWCNTs).The complexes were prepared by simple sonication of pristine SWCNTs in a solution of siRNA,which then served both as the cargo and as the suspending agent for the *** complexes containing siRNA targeted to hypoxia-inducible factor 1 alpha(HIF-1)were added to cells growing in serum containing culture media,there was strong specific inhibition of cellular HIF-1 *** ability to obtain a biological response to SWCNT/siRNA complexes was seen in a wide variety of cancer cell ***,intratumoral administration of SWCNT-HIF-1 siRNA complexes in mice bearing MiaPaCa-2/HRE tumors signifi cantly inhibited the activity of tumor *** elevated levels of HIF-1 are found in many human cancers and are associated with resistance to therapy and decreased patient survival,these results imply that SWCNT/siRNA complexes may have value as therapeutic agents.
