The performance of European enterprise during the Twentieth century : general overview
No full textThis chapter provides an introduction to and summary of the first attempt at measuring European business performance over the entire twentieth century on a common basis of data. In doing so, it adopts a new approach to European business history. Based on a single sample of 1,225 companies, from eight European economies (Britain, France, Germany, Italy, Spain, Belgium, Sweden, and Finland), it describes the basic questions dealt with by the various authors of this book in their chapters. Performance has been measured in terms of return on equity (ROE) and holding return (HR), thus providing a complementary measure of profitability, the former from the firm’s perspective, the latter from the investor’s perspective. The findings are summarized and compared. The results are sometimes surprising, at once confirming and challenging widely held assumptions regarding business performance—regarding strategy and structure, ownership and control, old and new industries, and emerging and advanced economies

Brain views that benefit from three-dimensional ultrasound
No full textPURPOSE OF REVIEW: Fetal central nervous system malformations are among the most common congenital anomalies. Whereas simple axial views are sufficient for basic fetal brain examination, other important views are essential for a more detailed examination, which are sometimes challenging to obtain. Three-dimensional ultrasound can be helpful in obtaining standardized and reproducible images of many difficult fetal brain views. The aim of the present review is to explore the most recent evidence on the utility and technique of three-dimensional ultrasound in the examination of the fetal brain, with particular emphasis on the brain views that benefit from three-dimensional ultrasound. RECENT FINDINGS: The article describes the various techniques of acquisition and analyses of three-dimensional ultrasound volumes of the fetal brain and their usefulness in the assessment of normal and abnormal fetal brain anatomy. Three-dimensional ultrasound has also permitted the application of many new technologies, such as artificial intelligence and deep machine learning. Recently, thanks to high-quality three-dimensional ultrasound, fetal cortical development can be assessed quantitatively and reliably. SUMMARY: Three dimensional ultrasound can help as a complementary tool to two-dimensional ultrasound in the assessment of the fetal brain development and malformations. In addition, it paves the way for the application of promising technologies in the evaluation of fetal brain. VIDEO ABSTRACT: A video summarizing the findings of the article. The video illustrates the various approaches and techniques applied for the examination of the fetal brain using three-dimensional ultrasound. Furthermore, the advantages and future perspectives of the application of three-dimensional ultrasound in the examination of the fetal brain are discussed, http://links.lww.com/COOG/A74
The performance of European business in the twentieth century
No full textThis book originated from the idea that performance is what really matters in business and thus in business history. Yet, surprisingly, the analysis of performances has been neglected by economic and business historians. This book is a first attempt to fill this gap and in doing so provides a totally new approach to European business history. Rather than bringing together national studies, it is based on a single database, measuring performance in eight European countries according to identical criteria. The study spans the entire twentieth century, with particular attention to five benchmark moments: the height of the first globalisation on the eve of the First World War; the late 1920s boom preceding the Great Depression; the European reconstruction of the mid-1950s; the end of 'Golden Age' in the early 1970s; and the height of the second globalisation at the turn of the twenty-first century. The analysis is based on a sample of 1,225 companies, belonging to the three major European economies, Britain, France and Germany; two large south European latecomers, Italy and Spain; two smaller north western countries, Belgium and Sweden, and one small Nordic country, Finland. Performance has been measured using two ratios of profitability: return on equity (ROE) and holding return (HR), thus providing a complementary measure of profitability, the former as seen from the firm's perspective, the latter form the investor's perspective. The book's findings, at times surprising, at once confirm and infirm widely held assumptions regarding business performance - regarding strategy and structure, ownership and control, old and new industries, emerging and advanced economies.-- Foreword, Franco Amatori

Validation of the antioxidant and enzyme inhibitory potential of selected triterpenes using in vitro and in silico studies, and the evaluation of their admet properties
No full textThe antioxidant and enzyme inhibitory potential of fifteen cycloartane-type triterpenes’ potentials were investigated using different assays. In the phosphomolybdenum method, cycloalpio-side D (6) (4.05 mmol TEs/g) showed the highest activity. In 1,1-diphenyl-2-picrylhydrazyl (DPPH*) radical and 2,2′-azino-bis(3-ethylbenzothiazoline)-6-sulfonic acid (ABTS) cation radical scavenging as-says, cycloorbicoside A-7-monoacetate (2) (5.03 mg TE/g) and cycloorbicoside B (10) (10.60 mg TE/g) displayed the highest activities, respectively. Oleanolic acid (14) (51.45 mg TE/g) and 3-O-β-D-xylopyranoside-(23R,24S)-16β,23;16α,24-diepoxycycloart-25(26)-en-3β,7β-diol 7-monoacetate (4) (13.25 mg TE/g) revealed the highest reducing power in cupric ion-reducing activity (CUPRAC) and ferric-reducing antioxidant power (FRAP) assays, respectively. In metal-chelating activity on ferrous ions, compound 2 displayed the highest activity estimated by 41.00 mg EDTAE/g (EDTA equiva-lents/g). The tested triterpenes showed promising AChE and BChE inhibitory potential with 3-O-β-D-xylopyranoside-(23R,24S)-16β,23;16α,24-diepoxycycloart-25(26)-en-3β,7β-diol 2′,3′,4′,7-tetraacetate (3), exhibiting the highest inhibitory activity as estimated from 5.64 and 5.19 mg GALAE/g (galan-tamine equivalent/g), respectively. Compound 2 displayed the most potent tyrosinase inhibitory activity (113.24 mg KAE/g (mg kojic acid equivalent/g)). Regarding α-amylase and α-glucosidase inhibition, 3-O-β-D-xylopyranoside-(23R,24S)-16β,23;16α,24-diepoxycycloart-25(26)-en-3β,7β-diol (5) (0.55 mmol ACAE/g) and compound 3 (25.18 mmol ACAE/g) exerted the highest activities, respectively. In silico studies focused on compounds 2, 6, and 7 as inhibitors of tyrosinase revealed that compound 2 displayed a good ranking score (−7.069 kcal/mole) and also that the ∆G free-binding energy was the highest among the three selected compounds. From the ADMET/TOPKAT prediction, it can be concluded that compounds 4 and 5 displayed the best pharmacokinetic and pharmacodynamic behavior, with considerable activity in most of the examined assays
Thromboprophylaxis in outpatients with COVID-19: a safe bet or tilting at windmills?
No full textEvidence for numerous therapies with antithrombotic, immunomodulatory, and anti-inflammatory properties in COVID-19 continues to rapidly evolve2. While we do not expect clinical trial data on routine thromboprophylaxis use in the outpatient setting to be released quite soon, current available data suggests the need for randomized trials that address the putative benefits of thromboprophylaxis in selected, high risk categories of COVID-19 outpatients, who may benefit from lowering their likelihood of developing pulmonary and systemic thrombosis. However, given the low risk of venous thromboembolism in this setting, routine pre-hospital thromboprophylaxis seems to remain unwarranted as yet. Vaccination remains the best intervention for reliable protection and preventing severe disease, hospitalization, and death
“Much ado about nothing”: Short selling ban effectiveness on bank stock prices
No full textMost regulators around the world reacted to the 2007-09 crisis by imposing bans on short selling. Using data from seven equity markets, this study empirically examines the impact of the 2008 short-selling bans on financial stocks.
Using panel and matching techniques, evidence indicates that bans on short-selling (i) on the whole widen volatility both in terms of High-Low spread and GARCH analysis, (ii) were not able to reduce systematic risk, (iii) overall failed to support prices. On the whole our results are in line with previous literature
