Shifts in coastal sediment oxygenation cause pronounced changes in microbial community composition and associated metabolism

BACKGROUND: A key characteristic of eutrophication in coastal seas is the expansion of hypoxic bottom waters, often referred to as 'dead zones'. One proposed remediation strategy for coastal dead zones in the Baltic Sea is to mix the water column using pump stations, circulating oxygenated water to the sea bottom. Although microbial metabolism in the sediment surface is recognized as key in regula

Transplant experiments uncover Baltic Sea basin-specific responses in bacterioplankton community composition and metabolic activities

Anthropogenically induced changes in precipitation are projected to generate increased river runoff to semi-enclosed seas, increasing loads of terrestrial dissolved organic matter and decreasing salinity. To determine how bacterial community structure and functioning adjust to such changes, we designed microcosm transplant experiments with Baltic Proper (salinity 7.2) and Bothnian Sea (salinity 3.

Concomitant use of pembrolizumab and entinostat in adult patients with metastatic uveal melanoma (PEMDAC study) : Protocol for a multicenter phase II open label study

Background: While recent years have seen a revolution in the treatment of metastatic cutaneous melanoma, no treatment has yet been able to demonstrate any prolonged survival in metastatic uveal melanoma. Thus, metastatic uveal melanoma remains a disease with an urgent unmet medical need. Reports of treatment with immune checkpoint inhibitors have thus far been disappointing. Based on animal experi

Tenascin-C expression by fibroblasts is elevated in stressed collagen gels

Chick embryo fibroblasts cultured on a collagen matrix exert tractional forces leading to the contraction of unrestrained, floating collagen gels and to the development of tension in attached, restrained gels. On a restrained, attached collagen gel the fibroblasts synthesize large quantities of tenascin-C, whereas in a floating, contracting gel tenascin-C synthesis is decreased. This regulation of

The mass-to-light ratio of rich star clusters

We point out a strong time evolution of the mass-to-light conversion factor, η, commonly used to estimate masses of unresolved star clusters from observed cluster spectrophotometric measures. We present a series of gas-dynamical models, coupled with the Cambridge stellar evolution tracks, to compute line-of-sight velocity dispersions and half-light radii weighted by the luminosity. We explore a ra

Tides in Colliding Galaxies

Long tails and streams of stars are the most noticeable traces of galaxy collisions. However, their tidal origin was recognized only less than 50 years ago and more than 10 years after their first observations. This review describes how the idea of galactic tides has emerged thanks to advances in numerical simulations, from the first simulations that included tens of particles to the most sophisti

coreMRI: A high-performance, publicly available MR simulation platform on the cloud

IntroductionA Cloud-ORiented Engine for advanced MRI simulations (coreMRI) is presented in this study. The aim was to develop the first advanced MR simulation platform delivered as a web service through an on-demand, scalable cloud-based and GPU-based infrastructure. We hypothesized that such an online MR simulation platform could be utilized as a virtual MRI scanner but also as a cloud-based, hig

Fracture incidence after tibial shaft fractures. A 30-year follow-up study

Based on all patients with tibial shaft fracture (n = 767) treated in the department of orthopedics in Malmö from 1955 to 1963, a retrospective cohort study was performed in 1990. Two hundred sixty-nine of the patients were still living in Malmö or had died in the city. Since all roentgenograms were available, all other fractures that this group of patients had sustained up to 1990 were included.

Comparison of Voxel-Wise and Histogram Analyses of Glioma ADC Maps for Prediction of Early Therapeutic Change

Noninvasive imaging methods are sought to objectively predict early response to therapy for high-grade glioma tumors. Quantitative metrics derived from diffusion-weighted imaging, such as apparent diffusion coefficient (ADC), have previously shown promise when used in combination with voxel-based analysis reflecting regional changes. The functional diffusion mapping (fDM) metric is hypothesized to

Radiology in cutaneous sinuses and fistulae

In patients with cutaneous openings, sinograph and fistulography are usually performed. Fistulae in the head/neck region and perineum are seldom life-threatening while enterocutaneous fistulae involving the small bowel can be a serious threat due to loss of fluid. Radiology contributes to the preoperative examination of these patients. Fistulography outlines communications to the gastrointestinal

ETV6/FLT3 fusion in a mixed-phenotype acute leukemia arising in lymph nodes in a patient with myeloproliferative neoplasm with eosinophilia

The ETV6/FLT3 fusion gene has been recently reported in association with myeloproliferative neoplasm with eosinophilia (MPN-Eo) and peripheral T cell lymphoma. Favorable clinical response to a targeted FLT3 tyrosine kinase inhibitor (FLT3 TKI) was noted. Here we report a novel phenotype associated with ETV6/FLT3 rearrangement, in a 38-year-old female with presentation of progressive lymphadenopath

Single target acuity is not higher than grating acuity in a bird, the budgerigar

We examined the capacity of budgerigars (Melopsittacus undulatus)to visually detect dark single targets against a brighter background and established their spatial resolution limit for such targets. While the sampling density of the retina limits the resolution of gratings, target detection is theoretically limited by contrast sensitivity. This allows many animals to detect single targets smaller

Alpha1-microglobulin chromophores are located to three lysine residues semiburied in the lipocalin pocket and associated with a novel lipophilic compound

Alpha1-microglobulin (alpha1m) is an electrophoretically heterogeneous plasma protein. It belongs to the lipocalin superfamily, a group of proteins with a three-dimensional (3D) structure that forms an internal hydrophobic ligand-binding pocket. Alpha1m carries a covalently linked unidentified chromophore that gives the protein a characteristic brown color and extremely heterogeneous optical prope

Recombinant factor VIII products and inhibitor development in previously untreated patients with severe haemophilia A : Combined analysis of three studies

INTRODUCTION: Standard treatment of congenital haemophilia A is based on replacement therapy with coagulation factor VIII (FVIII) products. A major complication of FVIII therapy is the occurrence of IgG alloantibodies (inhibitors) that neutralize FVIII activity.AIM: The aim of the analysis was estimating the risk of high-titre inhibitor associated with the second-generation full-length product com
