Overconfident results with the bivariate random effects model for meta-analysis of diagnostic accuracy studies حسب Furuya-Kanamori, Luis

"…Diaz found that the performance of the bivariate model deteriorates when between-study heterogeneity increases and the number of studies decrease.5 Our simulation studies found similar results—with moderate levels of heterogeneity (tau2 = 1), the coverage probabilities of Se, Sp, and the diagnostic odds ratio (DOR) with the bivariate model dropped below the nominal level.6 Diagnostic accuracy studies usually favor sensitivity over specificity, or vice versa leading to diagnostic 2 × 2 tables with one or more of the cells with low frequency or zero counts. …"

Heat transfer measurements of Polyalpha-Olefin- boron nitride nanofluids for thermal management and lubrication applications حسب Sleiti, Ahmad K.

"…The heat transfer enhancement in terms of Nussel Number showed average and maximum values of 10%–13%, 17%–20% and 26%–29% for hBN concentration of 0.25%, 0.6% and 1%, respectively. Two competing phenomena affect the heat transfer performance: the increase/decrease in resistance to thermal diffusion sublayer when thermal conductivity increases and viscosity decreases, respectively. …"

AMPK Activation Attenuates Albumin-induced Alterations in Renal Tubular Cells In Vitro حسب Allouch, Soumaya

"…In contrast, metformin co-treatment restored the levels of phosphorylated AMPK, and suppressed activation of AKT and P70S6K in NRK-52E cells exposed to albumin. Notably, metformin also prevented albumin-induced EMT; this was marked by a 50% decrease in a-SMA and a 60% increase in E-cadherin expression. …"

25-Hydroxyvitamin D serum levels inversely correlate to disease severity and serum C-reactive protein levels in patients with hidradenitis suppurativa حسب Moltrasio, Chiara

"…Vitamin D exerts functions in skin physiology by modulating keratinocyte proliferation and different immunoregulatory processes.1 In several dermatoses, vitamin D correlates to disease severity and is significantly lower if compared to healthy subjects.2 Hidradenitis suppurativa (HS) is a chronic inflammatory disease characterized by painful suppurating lesions mainly localized in the folds.3 Kelly et al.4 conducted the first study assessing vitamin D status in HS, concluding that 75% of patients had vitamin D levels of less than 50 nmol/L compared to 40% of the general population. …"
