PURPOSE China's freshwater subtropical shallow lakes are increasingly eutrophic and susceptible to production of heavy growths or water blooms of cyanobacteria. One example was the heavy water bloom that occurred for the first time in Lake Xuanwu, in 2005, an urban lake located in Nanjing city. The aim of the present study was to determine dynamics of water(More)
Monomers of (-)-epigallocatechin (EGC), (-)-epigallocatechin gallate (EGCG), (-)-epicatechin (EC), (-)-epicatechin gallate (ECG), (-)-epigallocatechin 3-O-(3-O-methyl) gallate (EGCG3''Me) and (-)-3-O-methyl epicatechin gallate (ECG3'Me) (purity, >97%) were successfully prepared from extract of green tea by two-time separation with Toyopearl HW-40S column(More)
BACKGROUND AND OBJECTIVES Cryogen spray cooling (CSC) is used to minimize the risk of epidermal damage during laser dermatologic surgery. Since optimization of CSC permits the safe use of higher light doses, which improves therapeutic outcome in many patients with superficial skin lesions, studies have focused on understanding spray-surface interactions and(More)
Although cryogen spray cooling (CSC) is used to minimize the risk of epidermal damage during laser dermatologic surgery, optimization of the current cooling approach is needed to permit the safe use of higher light doses, which should improve the therapeutic outcome in many patients. The objective of this study was to measure the effect of spurt duration(More)
Cryogen spray cooling (CSC) is used to minimize the risk of epidermal damage during laser dermatologic therapy. However, the dominant mechanisms of heat transfer during the transient cooling process are incompletely understood. The objective of this study is to elucidate the physics of CSC by measuring the effect of initial substrate temperature (T0) on(More)
Cryogen spray cooling (CSC) is a heat extraction process that protects the epidermis from thermal damage during dermatologic laser surgery. The objective of the present work is to investigate radial and temporal variations in the heat transferred through the surface of a skin phantom during CSC. A fast-response thermal sensor is used to measure surface(More)
Machado-Joseph disease (MJD) is the most common type of autosomal dominant spinocerebellar ataxia caused by an expanded CAG repeat in the MJD1 gene. Intermediate CAG alleles have been previously described, and they tend to be associated with unusual manifestations of the nervous system. Here we describe a Chinese kindred with hereditary spinocerebellar(More)
A new nematode species, Pristionchus entomophilus n. sp., was collected during a soil sample survey in Yixing of Jiangsu province, eastern China. P. entomophilus n. sp. is distinguished by its unique characteristics. This new species is mainly hermaphroditic, with males seldom found. The new nematode has a similar body length but has much narrower body(More)
To appraise the efficacy and safety of prophylactic uterine artery embolization in pregnancy termination with placenta previa. A cohort of 54 consecutive patients with placenta previa underwent prophylactic uterine artery embolization before vaginal delivery from February 2012 to March 2015. Vaginal delivery was attempted in all patients. Cesarean section(More)
Cyanobacterial blooms, forming massive scum and various cyanotoxins, increasingly spread in a wide range of freshwater ecosystems. One heavy Microcystis bloom occurred in the entire Qinhuai River basin in 2010 summer for the first time. To determine the Microcystis populations and their spatial distributions along Qinhuai River, a molecular approach was(More)
