A field experiment with 24 treatments consisting of three perennial forage crops [alfalfa (Medicago sativa l. cv. AC longview), hybrid bromegrass (Bromus riparius Rehm & Bromus inermis leyss. cv. AC Success) and their mixture], four Cut 1 dates (approximately June 20, July 10, July 30 or August 20), and two fertilizer levels (unfertilized and fertilized) was established in late May 2014, on a Black Chernozem [Udic Boroll] silty clay soil. Forage dry matter yield [DMY], and concentration (g·kg−1 DM) of crude protein [CP], total digestible nutrients [TDN] and acid detergent fiber [ADF] data were collected over 3 years from 2015 to 2017. The fertilizer treatments were imposed in 2016 and 2017. Forage crops were initially cut at four Cut 1 dates, and again cut [Cut 2] in autumn (September 2 in 2015, November 7 in 2016 and October 5 in 2017). For all three forage crops, forage DMY usually increased when Cut 1 was delayed. Delaying Cut 1 reduced forage DMY for Cut 2. Total DMY (Cut 1 + Cut 2) for all three forage crops was highest from the combination of July 10 and late Autumn cuts. Alfalfa-bromegrass mixture produced higher DMY than bromegrass or alfalfa alone. Fertilizer application resulted in a significant increase in Cut 1 and total DMY for bromegrass. The CP concentration in Cut 1 forage usually declined as the forage crops matured. The CP concentration was highest for alfalfa, followed by alfalfa-bromegrass mixture, and much lower for bromegrass. There was little or no effect of forage crop maturity on the TDN and ADF concentrations in forage. The TDN concentration was higher and ADF concentration was lower in forage from alfalfa or alfalfa-bromegrass mixture than bromegrass. Fertilizer application significantly increased CP concentration for alfalfa-bromegrass mixture. Delaying harvesting for Cut 1 increased ADF yield and TDN yield un

在较早研究中指出,辐照虫体存活到成虫期在引起抵抗方面有作用的可能性并未被排除。并指出在体内成熟或用高剂量丙种射线处理后阻止其成熟的血吸虫能引起基本上不同类型的抵抗力。Tromba氏认为致弱蠕虫幼虫所需的紫外光辐照剂量和波长的变化大有关系。我们决定将幼虫暴露于比我们较早工作中所用的限度更严的紫外光辐照光谱,这一研究证明:曼氏血吸虫尾蚴暴露给阻止成熟的紫外光辐照能引起的抵抗力的程度,可与X射线或丙种射线辐照的尾蚴引起的抵抗力相媲美。

Fecal pancreatic elastase 1 (PE-1) has been advocated as a noninvasive marker of pancreatic function and allows detection of moderate and severe exocrine ins ufficiency. Few studies have evaluated the utility of measuring PE-1 in duodena l fluid for the diagnosis of pancreatic insufficiency. Our purpose was (1) to de termine the feasibility of measuring PE-1 concentrations in duodenal aspirates obtained through our endoscopic pancreatic function test (ePFT) in healthy subje cts and patients with chronic pancreatitis (CP) and (2) to determine correlation s between duodenal PE-1 concentrations and bicarbonate and lipase concentration s in duodenal fluid. Healthy subjects (HS) and CP patients underwent an ePFT wit h CCK or secretin. CP was defined as endoscopic retrograde pancreatography (ERP) -Cambridge class Ⅲ-Ⅳ, endoscopic ultrasound (EUS) score>5, or presence of pa ncreatic calcifications on CT scan. Duodenal fluid PE-1, lipase, and bicarbonat e concentrations were measured in each study group. Duodenal lipase and bicarbon ate concentrations were measured using an autoanalyzer (Roche Diagnostics, India napolis, IN). PE-1 was measured using an ElISA (Genova Diagnostics, Asheville, NC). Ten HS and 10 CP patients were studied. In the CCK test the median peak lip ase for HS and CP was 1605 and 113 IU/l, respectively (P l, respecti vely (p l, respectively, after CCK stimulation (p=0.046) and 87 and 17 μg/ml, respecti vely, after secretin stimulation (p=0.033). Statistically significant correlatio ns were found between > and peak lipase>> (r=0.83, P ll as > and peak > (r=0.65, P=0.037). Conclusions are as follows: (1) PE -1 concentrations can be measured from duodenal fluid obtained by endoscopic as piration. (2) Duodenal fluid PE-1 concentrations are decreased in CP com

国际祖母绿市场日益繁荣,贸易交流频繁,市场急需一个科学、规范、通用的颜色分级体系。Guild宝石实验室基于自身数十年的研究成果,根据孟塞尔颜色理论,结合贸易实际,以祖母绿比色石实物为支撑,开发出了一套科学、完善的祖母绿颜色分级体系。按照颜色三要素:色相、饱和度、明度,将颜色级别划分为五个级别:浅(light)、中(Medium)、浓(Intense)、艳(Vivid)、深(Deep)。其中,艳(Vivid)代表了饱和度和明度都比较高的颜色。基于商贸的实际需求,Guild再对艳绿色进行细分,推出Verdant Green(沃顿绿)。Verdant Green(沃顿绿)指艳绿色中饱和度和明度更高的绿色,代表祖母绿最顶级的颜色。
