BACKgROUND Sickle cell disease(SCD) is a disorder that results in increased hospitalizations and higher mortality. Advances in management have resulted in increases in life expectancy and led to increasing awareness of sickle cell hepatopathy(SCH).However, its impact in patients on the natural history and outcomes of SCD is not known. Our study aims to describe the prevalence of extreme hyperbilirubinemia(EH), one form of SCH, its effect on morbidity and mortality,and correlations between sickle cell genotype and SCH type. We hypothesize that EH is associated with higher morbidity and *** To investigate the effects of EH on morbidity and mortality among patients with *** This retrospective cohort study was performed using a database of patients with SCD treated at grady Memorial Hospital between May 2004 and January *** with EH(defined as total bilirubin above 13.0 mg/dL) were identified. A control group was identified from the same database with patients with total serum bilirubin ≤ 5.0 mg/dL. Electronic medical records were used to extract demographic information, laboratory values, radiology results, current medications, need for transfusions and mortality data. Two samples T-test, chi-squared test and Fisher's exact test were then used to compare the parameters between the two *** Out of the database, fifty-seven charts were found of patients with bilirubin > 13 mg/dL.

Journal of Water Resource and Protection 2017年第13期9卷 1587-1611页

作者： Lauben Muhangane john Bosco Nkurunungi Jane Yatuha morgan Andama Department of Biology Faculty of Science Mbarara University of Science and Technology Mbarara Uganda

This study determined the physico-chemical and bacterial quality of raw (bore-hole, springs, wells) and tap water sources from Nyaruzinga wetland for domestic use in Bushenyi Municipality. Forty samples of raw water were randomly collected from Kacuncu, Kyeitembe and Kikuba tributaries of the wetland and 40 samples of tap water generated from the same wetland were randomly drawn from Ishaka, Nyakabirizi and Central divisions of the Municipality. The samples were analyzed for apparent colour (AC), turbidity, electrical conductivity (EC), total hardness, pH, total iron, residual alum, free residual chlorine and faecal coliforms using standard methods and their values compared with standard local UNBS (2008) and international WHO (2011) drinking water quality guidelines. The results showed that the mean pH of the protected spring below Kikuba Hill (5.21);the AC (Pt/Co) of the borehole below Bweranyangi Junior School (17.28) and the surface well below Nyandozo Primary School (157.58) both situated in Kacuncu as well as the free residual chlorine (mg/L) in tap water at Kanyamabona Trading Centre, Ishaka division (0.192) were below the standard values of WHO (pH, 6.0 - 8.0;free residual chlorine, 0.2 - 0.5) and UNBS (AC, g/L) of all the selected water sources were within the WHO standards (EC, g/L) in all the tap water sources was also within the WHO guideline (g/L) of the surface well below Nyandozo Primary School were above WHO guidelines of gi Junior School (16.83) including the surface well below Kyeitembe Trading Centre (9.25) were above

铁锰结壳存在两种不同的产状，一种是铁锰氧化物围绕“核心”生长形成的球状结壳，另一种是铁锰氧化物在基底岩石上生长形成的被状结壳。本文对Ｒ／ＶＫａｉｍｉｋａｉ－Ｏ－Ｋａｎａｌｏａ船１９９３年１１月在约翰斯顿岛附近海域取得的铁锰结壳进行了矿物学和地球化学分析。该区铁锰结壳主要组成矿物为δ－ＭｎＯ＿２，Ｍｎ／Ｆｅ比值为２．０２，富Ｃｏ（０．８８１％），贫Ｃｕ（０．１％），稀土总量（ΣＲＥＥ）１９１８．２７ｐｐｍ，具明显的Ｃｅ正异常（δＣｅ＝２．６），是典型的水成成因铁锰结壳。除Ｃｕ、Ｎｉ金属外，该区结壳中的稀土含量也已接近陆地稀土矿床的稀土品位。对球状结壳来说，表面光滑的上部壳层富δ－ＭｎＯ＿２，Ｍｎ、Ｃｏ、Ｎｉ、Ｃｕ、Ｐ含量较高，而表面粗糙的下部壳层Ｓｉ、Ａｌ含量相对较高。而且上部壳层的Ｃｅ正异常高于下部。对被状结壳而言，Ｃｏ、Ｎｉ等金属含量由基岩向结壳表层增加。作者认为造成上述变化的主要原因是基底岩石和海水间的反应。Ｒ型因子分析得出四个主要因子：三价稀土元素因子，Ｍｎ、Ｆｅ、Ｃｏ、Ｔｉ、Ｋ、Ｎａ、Ｖ、Ｍｏ、Ｃｄ、Ｃａ、Ｐ因子，Ｔｉ、Ｃｕ、Ｃｄ、Ｚｎ因子，和Ｓｉ、Ａｌ因子。分别代表了铁锰氧化物的水成成矿作用（因子?

To understand moxibustion from the biological effect of local thermal stimulation

World Journal of Acupuncture-Moxibustion 2016年第3期26卷 31-37,48页

作者：黄凯裕梁爽陆露 Patrick john morgan 张建斌南京中医药大学第二临床医学院中国南京210023

Moxibustion is one of treatment modalities in Traditional Chinese Medicine（TCM）. Its working mechanism is activated through heat-induced local thermal stimulation. By reviewing and compiling clear, scientific analysis of the biological and physiological effects from local thermal heat, the authors provides a coherent and systemic source to aid us to form an understanding of the mechanism of moxibustion’s promotion of qi and blood circulation throughout the body from local thermal stimulation. This has been done by a rigorous review of previous studies of the thermal effect on the body. The following presents the local, distal and systemic biological effects from local thermal stimulation while also discussing the similarities and differences between local thermal stimulation and moxibustion.

Population growth, increasing drought, and natural resources degradation are significant global ***, management practices to improve soil health can address many of these issues in ways that are both good forthe farmer and the environment. In 2012, the United States Department of Agriculture (USDA) Natural ResourcesConservation Service initiated its“Unlock the Secrets in the Soil” campaign to assist farmers and ranchers with adoptingsoil health systems. Other notable efforts at the federal level include research and education projects by USDAAgricultural Research Service, National Instituite of Food and Agriculture, and Sustainable Agriculture Research andEducation program. The importance of improving soil health is also recognized far beyond federal government *** Soil Health Institute, a nonprofit charity, was established to safeguard and enhance the vitality and productivity of soilthrough scientific research and adoption. Crop commodity organizations are promoting soil health, such as the Soil HealthPartnership. The Nature Conservancy is helping companies and private landowners incorporate soil health into theirsustainability efforts. Such efforts are supported by the Foundation for Food and Agriculture Research, as well as by someof the leading global food companies such as general Mills. These are just a few of the many efforts to improve soil healthin the USA. The significance of the expanding global population, natural resource challenges, and responsibilities tocurrent and future generations truly make enhancing soil health a global imperative.
