Background: The extent of the COVID-19 pandemic and the resulting response has varied globally. The European and African Hepato-Pancreato-Biliary Association (E-AHPBA), the premier representative body for practicing HPB surgeons in Europe and Africa, conducted this survey to assess the impact of COVID-19 on HPB surgery. Methods: An online survey was disseminated to all E-AHPBA members to assess th
Det luriga, lilla ordet "lige" i danska.Der er et lillebitte (pyttelitet) ord i dansk, der giver mange af mine svenske studerende dybe panderynker, når de møder det på mine danskkurser ved Lunds universitet. Flere af dem har egentligt hørt ordet flere gange før, men har ikke helt kunnet knække koden.Ordet er ikke alene drilsk (lurigt), men til tider decideret farligt at have med at gøre, fordi det
Artikeln undersöker eurons konsekvenser för integration och tillväxt i Östersjöregionen (Polen, Litauen, Lettland, Estland, Finland och Sverige). Efter Sovjetunionens sammanbrott har de baltiska staterna och Polen snabbt hämtat in på Västeuropa. Den globala finanskrisen blev ett kraftigt bakslag för de förra, men i mindre utsträckning för Polen. Penningpolitiken har gjort skillnad: den polska zlotWhich have been the consequences of the euro for integration and economic performance in the Baltic Sea region? After the collapse of the Soviet Union, the three Baltic states and Poland have been rapidly catching-up with Western Europe. The Great Recession becamea great setback for the former, while less so for Poland. A difference is the monetary policy: the Polish zloty depreciated in t
Chronic respiratory diseases are among the leading causes of death worldwide, but only symptomatic therapies are available for terminal illness. This in part reflects a lack of biomimetic in vitro models that can imitate the complex environment and physiology of the lung. Here, a copolymeric membrane consisting of poly(ε-)caprolactone and gelatin with tunable properties, resembling the main charac
PURPOSE: To estimate the excess healthcare use and work disability attributable to knee osteoarthritis (OA) in the first five years following diagnosis.METHODS: Among individual aged 40-80 years who resided in Skåne on 31st December 2008, we identified those with a main diagnosis of knee OA during 2009-2014 and no previous diagnosis of any OA from 1998 (n=16,888). We created a comparison cohort ma
We present and analyze high resolution near edge X-ray absorption fine structure (NEXAFS) spectra of CO+ at the carbon and oxygen K-edges. The spectra show a wealth of features that appear very differently at the two K-edges. The analysis of these features can be divided into three parts; (i) repopulation transition to the open shell orbital-here the C(1s) or O(1s) to 5σ transition, where the norm
A general framework for determining fundamental bounds in nanophotonics is introduced in this paper. The theory is based on convex optimization of dual problems constructed from operators generated by electromagnetic integral equations. The optimized variable is a contrast current defined within a prescribed region of a given material constitutive relations. Two power conservation constraints anal
The authors investigated whether PCSK9 inhibition could represent a therapeutic strategy in calcific aortic valve stenosis (CAVS). A meta-analysis of 10 studies was performed to determine the impact of the PCSK9 R46L variant on CAVS, and the authors found that CAVS was less prevalent in carriers of this variant (odds ratio: 0.80 [95% confidence interval: 0.70 to 0.91]; p = 0.0011) compared with no
OBJECTIVES: Analyses performed by the Sarcopenia Definitions and Outcomes Consortium (SDOC) identified cut-points in several metrics of grip strength for consideration in a definition of sarcopenia. We describe the associations between the SDOC-identified metrics of low grip strength (absolute or standardized to body size/composition); low dual-energy x-ray absorptiometry (DXA) lean mass as previo
α-Chymotrypsin was deposited on Celite and the resulting immobilized preparations were used to carry out peptide synthesis reactions in organic media with only small amounts of water present. The influence of different parts of the donor ester and acceptor nucleophile substrate molecules on the kinetics of the enzymatic reactions was studied. The specificity of α-chymotrypsin in organic media was
BACKGROUND: The Sarcopenia Definitions and Outcomes Consortium (SDOC) sought to identify cut points for muscle strength and body composition measures derived from dual-energy x-ray absorptiometry (DXA) that discriminate older adults with slow walking speed. This article presents the core analyses used to guide the SDOC position statements. DESIGN: Cross-sectional data analyses of pooled data. SETT
Raptors from the orders Accipitriformes and Falconiformes have been considered to rely principally on vision. Historically, this assumption has led scientists to discount any possible sense of smell in these birds, until work on cathartid vultures indicated that these species at least rely on olfaction to find carrion. In this review I provide evidence that raptors in general have functional olfac
The proliferative activity of aging hematopoietic stem cells (HSCs) is controversially discussed. Inducible fluorescent histone 2B fusion protein (H2B-FP) transgenic mice are important tools for tracking the mitotic history of murine HSCs in label dilution experiments. A recent study proposed that primitive HSCs symmetrically divide only four times to then enter permanent quiescence. We observed t
In this work, we present a thorough analysis of scalar P -wave χQ0, Q = c, b quarkonia electromagnetic form factors for the γ∗γ∗→ χQ0 couplings, as well as their hadroproduction observables in k⊥-factorisation using the light-front (LF) potential approach for the quarkonium wave function. The electromagnetic form factors are presented as functions of photon virtualities. We discuss the role of the
