Evidence of rescattering effect in Pb–Pb collisions at the LHC through production of K(892)0⁎ and ϕ(1020) mesons

Measurements of K(892)0⁎ and ϕ(1020) resonance production in Pb–Pb and pp collisions at sNN = 5.02 TeV with the ALICE detector at the Large Hadron Collider are reported. The resonances are measured at midrapidity (|y| < 0.5) via their hadronic decay channels and the transverse momentum (pT) distributions are obtained for various collision centrality classes up to pT = 20 GeV/c. The pT-integrated y

Antimicrobial peptide LL-37 and its pro-form, hCAP18, in desquamated epithelial cells of human whole saliva

The antimicrobial peptide LL-37 is active against oral bacteria and has been demonstrated to be present in human saliva, but its distribution in different fractions of saliva is not known. LL-37 is formed from its intracellular pro-form, hCAP18, in an extracellular enzymatic reaction catalyzed by proteinase 3 and kallikrein 5. Here, we prepared cell-containing and cell-free fractions of unstimulat

The FLASH effect depends on oxygen concentration

OBJECTIVE: Recent in vivo results have shown prominent tissue sparing effect of radiotherapy with ultra-high dose rates (FLASH) compared to conventional dose rates (CONV). Oxygen depletion has been proposed as the underlying mechanism, but in vitro data to support this have been lacking. The aim of the current study was to compare FLASH to CONV irradiation under different oxygen concentrations in

Municipalities as enablers in urban experimentation

In the light of increasing urban challenges, municipalities are developing and advancing new forms of governing. One such example is ‘urban experimentation’, a process where city-based innovation processes are initiated to test solutions that – if deemed successful – are intended to be scaled up with the ambition to leverage a broader urban sustainability transition. Research on experimental gover

Mosquito counting system based on optical sensing

Mosquitos, sometimes carrying deadly diseases such as malaria, zika, and dengue fever, cause much concern. To control mosquitos, it is important to effectively monitor their presence and behavioral trends. We have constructed two optical sensing systems for insects based on light attenuation and light backscattering, respectively. The systems, which were tested with the potentially dangerous Aedes

Gaps between current clinical practice and evidence-based guidelines for treatment and care of older patients with Community Acquired Pneumonia : a descriptive cross-sectional study

BACKGROUND: Community acquired pneumonia (CAP) remains a significant cause of morbidity and in-hospital mortality, and readmission rates are rising for older persons (> 65 years). Optimized treatment and nursing care will benefit patients and the health economy. Hence, there is a need to describe gaps between current clinical practice and recommendations in evidence-based guidelines for diagnostic

How industry collaboration influences research: The case of the Swedish interdisciplinary materials consortia, 1990–2000

This article provides new insights into the consequences of university–industry collaboration for the content and conduct of academic research by analysing the Swedish research funding programme for the so-called ‘materials consortia’, in place between 1990 and 2000. Using secondary sources, the analysis highlights the causality in university–industry collaboration and the impact of such collabora

A cluster of missense mutations at Arg356 of human steroid 21-hydroxylase may impair redox partner interaction

Lesions in the gene encoding steroid 21-hydroxylase result in congenital adrenal hyperplasia, with impaired secretion of cortisol and aldosterone from the adrenal cortex and overproduction of androgens. A limited number of mutations account for the majority of mutated alleles, but additional rare mutations are responsible for the symptoms in some patients. A total of 11 missense mutations has prev

Parks and envelopes : Reconceptualizing the intersection of public and private interests in HK

This article aims to demonstrate that building envelopes can be designed to improve the performance of public open space in Hong Kong. It investigates how such improvement can be used to negotiate between objective and regulation in planning standards. Addressing a research site with a publicly accessible pocket park in the Mong Kok area, the article explores generative potentials at the interface

Seed dispersal and fine-scale genetic structuring in the asexual Nigritella miniata (Orchidaceae) in the Alps

Orchids have minute, air-filled seeds and are considered as efficient dispersers and colonizers. Yet, empirical studies show that most seeds fall within the nearest metre from the mother plant in orchids, and that individuals standing close to each other are often closely related. A poor contribution to gene dispersal by seeds may be compensated for by more efficient dispersal by pollen, but in auOrchids have minute, air-filled seeds and are considered to be efficient dispersers and colonizers. However, empirical studies show that most seeds fall within a metre of the mother plant in orchids, and that individuals standing close to each other are often closely related.

Molecular switch controlling expression of the mannose-specific adhesin, Msa, in Lactobacillus plantarum

Some lactic acid bacteria, especially Lactobacillus spp., possess adhesive properties enabling colonization of the human gastrointestinal tract. Two probiotic Lactobacillus plantarum strains, WCSF1 and 299v, display highly different mannose-specific adhesion, with L. plantarum 299v being superior to L. plantarum WCFS1 based on a yeast agglutination assay. A straightforward correlation between the

Phylogenomic relationships of diploids and the origins of allotetraploids in Dactylorhiza (Orchidaceae)

Disentangling phylogenetic relationships proves challenging for groups that have evolved recently, especially if there is ongoing reticulation. Although they are in most cases immediately isolated from diploid relatives, sets of sibling allopolyploids often hybridize with each other, thereby increasing the complexity of an already challenging situation. Dactylorhiza (Orchidaceae: Orchidinae) is a

Search for the Production of a Long-Lived Neutral Particle Decaying within the ATLAS Hadronic Calorimeter in Association with a Z Boson from pp Collisions at s =13 TeV

This Letter presents a search for the production of a long-lived neutral particle (Zd) decaying within the ATLAS hadronic calorimeter, in association with a standard model (SM) Z boson produced via an intermediate scalar boson, where Z→+ (=e, μ). The data used were collected by the ATLAS detector during 2015 and 2016 pp collisions with a center-of-mass energy of s=13 TeV at the Large Hadron Collid

Artros allt vanligare folksjukdom

Osteoarthritis is a multifactorial disease commonly affecting knee, hip, hand, and spine but other joints also may be affected. Well-known risk factors for symptomatic osteoarthritis include age, overweight or obesity, female gender, and joint injury. Accumulating evidence support that osteoarthritis progression is often driven by biomechanical forces, and the pathological response of tissues to s
