Considerable variation of trough β-lactam concentrations in older adults hospitalized with infection—A prospective observational study

In older adults, few studies confirm that adequate concentrations of antibiotics are achieved using current dosage regimens of intravenous β-lactam antibiotics. Our objective was to investigate trough concentrations of cefotaxime, meropenem, and piperacillin in older adults hospitalized with infection. We included 102 patients above 70 years of age. Total trough antibiotic concentrations were meas

Butterflies fly using efficient propulsive clap mechanism owing to flexible wings

Butterflies look like no other flying animal, with unusually short, broad and large wings relative to their body size. Previous studies have suggested butterflies use several unsteady aerodynamic mechanisms to boost force production with upstroke wing clap being a prominent feature. When the wings clap together at the end of upstroke the air between the wings is pressed out, creating a jet, pushin

Preferred sound groups of vocal iconicity reflect evolutionary mechanisms of sound stability and first language acquisition : evidence from Eurasia

In speech, the connection between sounds and word meanings is mostly arbitrary. However, among basic concepts of the vocabulary, several words can be shown to exhibit some degree of form–meaning resemblance, a feature labelled vocal iconicity. Vocal iconicity plays a role in first language acquisition and was likely prominent also in pre-historic language. However, an unsolved question is how voca

Morphometric analysis of disjunct Papaver radicatum (Papaveraceae) populations in southern Norway

Morphometric relationships between populations of Papaver radicatum within the southern Norwegian mountains were investigated using canonical variates analysis and Ward's clustering on capsule and leaf character sets. The survey describes patterns of variation among 13 wild-scored populations from five geographically disjunct localities, usually assigned to five races or subspecies. Our results fr

EFFECT OF KIDNEY STEM CELLS ON BIOCHEMICAL ANALAYSIS AND SMAD2/3 PHOSPHORYLATION IN RATS WITH DIABETIC NEPHROPATHY

Introduction: Mesenchymal stem cells (MSCs) were proposed as a critical therapeutic candidate in diabetic nephropathy (DN). Renal stem cells as a source for repairing are controversial. The purpose of the present study was to evaluate the effect of kidney rat stem cells on DN. Materials and methods: After separation of renal stem cells from rat kidney, the surface Stem cell markers were assessed b

Effect of level of sedation on outcomes in critically ill adult patients : a systematic review of clinical trials with meta-analysis and trial sequential analysis

Background: Sedation is routinely administered to critically ill patients to alleviate anxiety, discomfort, and patient-ventilator asynchrony. However, it must be balanced against risks such as delirium and prolonged intensive care stays. This study aimed to investigate the effects of different levels of sedation in critically ill adults. Methods: Systematic review with meta-analysis and trial seq

The Intermediality of Performance

This chapter looks at how different kinds of bodies and objects interact in a performance and at how the presence and emergence of an event interact with mediation and transmediation. Our intermedial approach allows us to explore the entanglement of presence and representation, of performance and media products, of performativity and intermediality. Through a combination of the perspectives of per

Mass transfer in white dwarf-neutron star binaries

We perform hydrodynamic simulations of mass transfer in binaries that contain a white dwarf and a neutron star (WD-NS binaries), and measure the specific angular momentum of material lost from the binary in disc winds. By incorporating our results within a long-term evolution model, we measure the long-term stability of mass transfer in these binaries. We find that only binaries containing helium

Quantitative versus standard pupillary light reflex for early prognostication in comatose cardiac arrest patients : an international prospective multicenter double-blinded study

Purpose: To assess the ability of quantitative pupillometry [using the Neurological Pupil index (NPi)] to predict an unfavorable neurological outcome after cardiac arrest (CA). Methods: We performed a prospective international multicenter study (10 centers) in adult comatose CA patients. Quantitative NPi and standard manual pupillary light reflex (sPLR)—blinded to clinicians and outcome assessors—

Weak Shape Anisotropy Leads to a Nonmonotonic Contribution to Crowding, Impacting Protein Dynamics under Physiologically Relevant Conditions

The effect of a nonspherical particle shape on the dynamics in crowded solutions presents a significant challenge for a comprehensive understanding of interaction and structural relaxation in biological and soft matter. We report that small deviations from a spherical shape induce a nonmonotonic contribution to the crowding effect on the short-time cage diffusion compared with spherical systems, u
