What are the Benefits and Harms of Ureteroscopy Compared with Shock-wave Lithotripsy in the Treatment of Upper Ureteral Stones? A Systematic Review

Context: Extracorporeal shock wave lithotripsy (SWL) and ureteroscopy (URS), with or without intracorporeal lithotripsy, are the most common treatments for upper ureteric stones. With advances in technology, it is unclear which treatment is most effective and/or safest. Objective: To systematically review literature reporting benefits and harms of SWL and URS in the management of upper ureteric st

"The Spirit of 1914": A Redefinition and a Defense

The received wisdom has long been that people in Europe reacted with great enthusiasm as war was approaching in August, 1914. However, scholars who have investigated the matter have found little evidence of enthusiasm. There was no unique “spirit of 1914,” and people in general were not happy about the prospect of war. This revisionist thesis is now the new orthodoxy and should as such be subject The received wisdom has long been that people in Europe reacted with great enthusiasm as war was approaching in August, 1914.

Vocational situation and experiences from the work environment among individuals with neuromuscular diseases

BACKGROUND: Neuromuscular diseases (NMD) can affect the ability to be employed and to work, but there is limited knowledge of individuals' own perspectives of factors that are important for their vocational situation. OBJECTIVE: To explore the vocational situation among people with NMD that are employed, and to describe their experiences of how their disability, personal and environmental factors

Extremely different behaviours in high and low body weight lines of chicken are associated with differential expression of genes involved in neuronal plasticity

Long-term selection (>45 generations) for low or high body weight from the same founder population has generated two extremely divergent lines of chickens, the low (LWS) and high weight (HWS) lines, which at the age of selection (56days) differs by more than nine-fold in body weight. The HWS line chickens are compulsive feeders, whereas, in the LWS line, some individuals are anorexic and others ha

Aerodynamic performance in bat flight

Den här avhandlingen handlar om aerodynamik hos fladdermöss. Det vill säga, hur fladdermöss skapar de krafter som låter dem flyga, hur de påverkar luften för att åstadkomma detta, och hur deras vingar rör sig när de gör det.Tack vare förmågan att flyga kan djur utnyttja annars otillgängliga födoämnen, undfly rovdjur, och övervintra i varmare trakter. Fördelarna med flygning blir än mer uppenbara nBats are the only mammals capable of flight, and they are the only animal flyers that are mammals. This thesis focuses on the latter of those facts, and investigates how bats fly, from an aerodynamic perspective. The data on which this thesis is based were generated by examining the airflows beneath and behind bats flying in a wind tunnel, and by examining their wing kinematics manually and automa

The impact of stellar feedback on the density and velocity structure of the interstellar medium

We study the impact of stellar feedback in shaping the density and velocity structure of neutral hydrogen (H I) in disc galaxies. For our analysis, we carry out ~4.6 pc resolution N-body+adaptive mesh refinement hydrodynamic simulations of isolated galaxies, set up to mimic a Milky Way and a Large and Small Magellanic Cloud. We quantify the density and velocity structure of the interstellar medium

Variation in rhinarium temperature indicates sensory specializations in placental mammals

The rhinarium, a specialized nose-tip characterized by an area of naked and wet skin around the nostrils, is a typical mammalian structure. The type and amount of innervation suggests a sensory role and morphological diversity implies so far unidentified species-specific functional specializations. Rhinaria also vary in temperature and this may be related to the functions of these sensory organs.

Sequential Targeting of Xylose and Glucose Conversion in Fed-Batch Simultaneous Saccharification and Co-fermentation of Steam-Pretreated Wheat Straw for Improved Xylose Conversion to Ethanol

Efficient conversion of both glucose and xylose in lignocellulosic biomass is necessary to make second-generation bioethanol from agricultural residues competitive with first-generation bioethanol and gasoline. Simultaneous saccharification and co-fermentation (SSCF) is a promising strategy for obtaining high ethanol yields. However, with this method, the xylose-fermenting capacity and viability o

Tumor necrosis factor-α-mediated downregulation of the cystic fibrosis transmembrane conductance regulator drives pathological sphingosine-1-phosphate signaling in a mouse model of heart failure

Background-Sphingosine-1-phosphate (S1P) signaling is a central regulator of resistance artery tone. Therefore, S1P levels need to be tightly controlled through the delicate interplay of its generating enzyme sphingosine kinase 1 and its functional antagonist S1P phosphohydrolase-1. The intracellular localization of S1P phosphohydrolase-1 necessitates the import of extracellular S1P into the intra

Early Holocene dune field development in Dalarna, central Sweden : A geomorphological and geophysical case study

Bonäsheden, Sweden's largest continuous dune field, situated in the county of Dalarna, central Sweden, has been investigated using LiDAR (light detection and ranging) remote sensing, ground penetrating radar as well as by field observations and luminescence dating. The use of LiDAR in conjunction with geographic information system (GIS) software proved to be efficient in mapping the inactive dune

Variation in growth drives the duration of parental care : A test of Ydenberg’s model

The duration of parental care in animals varies widely, from none to lifelong. Such variation is typically thought to represent a trade-off between growth and safety. Seabirds show wide variation in the age at which offspring leave the nest, making them ideal to test the idea that a trade-off between high energy gain at sea and high safety at the nest drives variation in departure age (Ydenberg’s

Mechanical symptoms as an indication for knee arthroscopy in patients with degenerative meniscus tear : a prospective cohort study

OBJECTIVE: According to prevailing consensus, patients with mechanical symptoms are those considered to most likely benefit from arthroscopic surgery. The aim of this study was to determine the value of using patients' pre-operative self-reports of mechanical symptoms as a justification surgery in patients with degenerative meniscus tear/knee disease.DESIGN: Pragmatic prospective cohort of 900 con

Monetary Aggregates for Ireland, 1840-1921

This article constructs new monetary aggregates for Ireland between 1840 and 1921.Three major findings are gleaned from the data. First, we find that the degreeof monetization on the eve of the Famine was comparatively high. Second, wefind an unprecedented monetary contraction during the Famine. Third, in contrastto previous research, we find that the failure of the Munster Bank in 1885 hadramification

The gamma-tubulin meshwork as a therapeutic target

Cancer is a heterogeneous disease and treatment regime is dependent on type and location of the tumor. Several of the commonly used chemotherapeutics target the functions of the microtubules. One of the major problems with these drugs is the adverse effects associated with their use. Another problem many of the chemotherapeutics today face is resistance. Therefore there is a constant need for deve

Leisure activities and mobility device use among very old people in Latvia and in Sweden

Introduction Opportunities for leisure activities and physical mobility are important for the ageing population. Therefore, we aim to describe leisure activities outside the home among very old (over 80 years of age) users and non-users of mobility devices in two European countries. Method Survey data on mobility device use, self-rated physical mobility and leisure activities outside the home were

Surgical management of degenerative meniscus lesions : The 2016 ESSKA meniscus consensus

Purpose: A degenerative meniscus lesion is a slowly developing process typically involving a horizontal cleavage in a middle-aged or older person. When the knee is symptomatic, arthroscopic partial meniscectomy has been practised for a long time with many case series reporting improved patient outcomes. Since 2002, several randomised clinical trials demonstrated no additional benefit of arthroscop
