    Diagnosing type 2 diabetes using Hemoglobin A1c: a systematic review and meta-analysis of the diagnostic cutpoint based on microvascular complications حسب Alexandra E. Butler (6189536)

    منشور في 2020
    "…</p><h3>Conclusions</h3><p dir="ltr">The prevalence of nephropathy and moderate retinopathy was increased in subjects with HbA1c values ≥ 6.5% confirming the high specificity of this value for diagnosing T2DM; however, at HbA1c < 6.5% retinopathy increased at age > 55 years and, most strikingly, in African-Americans, suggesting there may be excess microvascular complication prevalence (particularly nephropathy) in individuals below the diabetes diagnostic threshold.…"

    Finite Element Analysis of the Mechanism of Traumatic Aortic Rupture (TAR) حسب JiFeng Nan (14571246)

    منشور في 2020
    "…The finite element analysis indicated that maximum stress and strain applied to the aorta were from 5.4819e5 to 2.614e6 Pa and 0.21048 to 0.62676, respectively, in the <em>Y</em>-direction when the initial velocity increased from 10 to 25 m/s. Furthermore, in the <em>X</em>-direction when the velocity changed from 15 to 25 m/s, the stress and strain values increased from 5.17771e5 to 2.3128e6 and from 0.22445 to 0.618, respectively. …"

    Space size relative to prey width and total cover in an area both influence the habitat choices of freshwater angelfish Pterophyllum scalare in mesocosms حسب Bartholomew, Aaron

    منشور في 2012
    "…Prey survivorship can vary with average space size/prey width (Sp/Py) and total cover within an area (Ct/At). Hypotheses predict that prey survivorship is maximized at intermediate Sp/Py values and that prey survivorship increases rapidly from zero to low cover but increases at a slower rate as cover increases further. …"

    Effectiveness of Positron Emission Tomography for Predicting Chemotherapy Response in Colorectal Cancer Liver Metastases حسب Glazer, Evan

    منشور في 2010
    "…For example, a few years ago an extrahepatic metastasis effectively eliminated surgical resection, but a combination of chemotherapeutic options and surgical techniques has expanded the indications for resection and increased the population of patients who may benefit.1,2 Neoadjuvant chemotherapy has increased the resectability rate by 11% to 37%.1 Unfortunately, greater than 80% of patients undergoing hepatic resection will have recurrences, mostly within the first 2 years.2 Nonetheless, the only hope for cure is resection, and prior surgical dogma based on the number of lesions, size of the tumor-free resection margin, and presence of resectable extrahepatic disease must be questioned.3- 5 The current standard approach to surgical planning is contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI) for specific tumor characteristics or contraindications to CT.6 Several series showed that focal extrahepatic disease, an isolated pulmonary lesion, can be safely resected, with 5-year survival rates of 29% to 58%.7,8 In 1 series,7 17 of 30 patients required 3 or more resections. …"
