Under the assumption that the underlying measure is a non-negative Radon measure which only satisfies some growth condition and may not be doubling, we define the product of functions in the regular BMO and the atomic block -~1 in the sense of distribution, and show that this product may be split into two parts, one in L1 and the other in some Hardy-Orlicz space.

AIM： To distinguish anastomotic from parenchymal leakage at duct-to-mucosa reconstruction of the pancreatic remnant. METHODS： We reviewed the charts of 68 pancreaticoduodenectomies performed between 5/2000 and 12/2005 with end-to-side duct-to-mucosa pancreatojejunostomy （PJ）. The results of pancreatography, as well as peripancreatic drain volumes, and amylase levels were analyzed. RESULTS： Of 68 pancreatojejunostomies, 48 had no leak by pancreatography and had low-drain amylase （normal）; eight had no pancreatographic leak but had elevated drain amylase （parenchymal leak）; and 12 had pancreatographic leak and elevated drain amylase （anastomotic leak）. Although drain volumes in the parenchymal leak group were significantly elevated at postoperative day （POD） 4, no difference was found at POD 7. Drain amylase level was not significantly different at POD 4. In contrast, at POD 7, the anastomotic-leak group had significantly elevated drain amylase level compared with normal and parenchymalleak groups （14158 ＋ 24083 IU/L vs 89 ＋ 139 IU/L and 1707 ＋ 1515 IU/L, respectively, P = 0.012）. CONCLUSION： For pancreatic remnant reconstruction after pancreaticoduodenectomy, a combination of pancreatogram and peripancreatic drain amylase levels can be used to distinguish between parenchymal and anastomotic leakage at pancreatic remnant reconstruction.

A large number of women will pass through menopause each year. Women in menopausal transition experience a variety of menopausal symptoms. Although hormonal therapy remains the most effective treatment, side effects have been reported by several large studies. An increased number of women seek the use of complementary and alternative medicine （CAM） for treating menopausal symptoms. This review analyzes the evidence from systematic reviews, randomized controlled trials and epidemiological studies of using herbal medicine （Black cohosh, Dong quai, St John＇s wart, Hops, Wild yam, Ginseng, and evening primrose oil） and acupuncture for the treatment of menopausal symptoms. Evidence supporting the efficacy and safety of most CAM for relief of menopausal symptoms are limited. Future larger and better controlled studies testing the effectiveness of these treatments are needed.

As sessile organisms plants must ronmental conditions. To survive cope with ever changing enviplants have evolved elaborate mechanisms to perceive and rapidly respond to a diverse range of abiotic and biotic stresses. Central to this response is the ability to modulate gene expression at both the transcriptional and posttranscriptional levels. This review will focus on recent progress that has been made towards understanding the rapid reprogramming of the transcriptome that occurs in response to stress as well as emerging mechanisms underpinning the reprogramming of gene expression in response to stress,
