It is possible to calculate the expected average fragment size for a given genomic DNA if the percent GC content of the DNA and the recognition sequence of the restriction enzyme are known. For example, in a genome with 50% GC content and no dinucleotide bias, a four-cutter can be expecte...
The mean transit time is measured with each bolus and averaged to calculate the resting mean transit time. When steady-state hyperemia is achieved by pharmacological stress testing, 3 additional injections of 3 ml of room-temperature saline are performed. The transit time is automatically measured ...
Retrospectively analyzing data from the Cooperative Study of Sickle Cell Disease (CSSCD) to calculate incidence rates for first-time VTE, Naik and colleagues found an incidence rate of 5.2 events per 1000 person-years (95% confidence interval [CI], 3.8-6.9) in 1523 SCD patients aged ≥15 ...
Drain volume is inversely correlated to solute transport rate. PET建立在血浆与透析液中溶质浓度的平衡以及腹膜对葡萄糖吸收作用的基础上. 透析液和血浆中溶质浓度的比值(D/P)如肌酐、尿素、钾离子:随着血液中肌酐顺着浓度梯度弥散入腹腔内,透析液中肌酐浓度逐渐增加. 留腹期间透析液中葡萄糖的浓度随着腹膜对葡萄...
6 Also, this study used quantitative angiography to calculate the arterial and minimal luminal diameter. Follow-up consisted of quantitative angiography and histomorphometry after 5 months. Stent segments were divided into "normal-sized" (stent-to-artery ratio < 1.4) and "oversized" (sten...
To calculate the calcium level, it is necessary to consider that, in hypo-/hyperalbuminemia, it must be corrected, since 40% of serum calcium is bound to albumin, as detailed below. Albumin < 40 g/dL: corrected calcium = (Ca2+) + 0.02 [40 − (albumin)] Albumin ≥ 40 g/dL: ...

62,63 The FIBTEM test (ROTEM device) has been used extensively to determine fibrinogen levels and calculate dosing as reported in clinical trials.1,34,64 Maximal amplitude, an equivalent parameter to MCF, can be measured using a functional fibrinogen assay on the TEG device. The fibrinogen ...
