Ambient temperature effects on stress-induced hyperthermia in Svalbard ptarmigan
Stress-induced hyperthermia (SIH) is commonly observed during handling in homeotherms. However, in birds, handling in cold environments typically elicits hypothermia. It is unclear whether this indicates that SIH is differently regulated in this taxon or if it is due to size, because body temperatures changes during handling in low temperature have only been measured in small birds ≤0.03 kg (that Stress-induced hyperthermia (SIH) is commonly observed during handling in homeotherms.

Massive MIMO-based Localization and Mapping Exploiting Phase Information of Multipath Components
In this paper, we present a robust multipath-based localization and mapping framework that exploits the phases of specular multipath components (MPCs) using a massive multiple-input multipleoutput (MIMO) array at the base station. Utilizing the phase information related to the propagation distances of the MPCs enables the possibility of localization with extraordinary accuracy even with limited ba
Long-term Outcome of Antiretroviral Treatment in Patients With and Without Concomitant Tuberculosis Receiving Health Center-Based Care-Results From a Prospective Cohort Study
Background: In order to increase treatment coverage, antiretroviral treatment (ART) is provided through primary health care in low-income high-burden countries, where tuberculosis (TB) co-infection is common. We investigated the long-term outcome of health center-based ART, with regard to concomitant TB.Methods: ART-naïve adults were included in a prospective cohort at Ethiopian health centers and
Deep learning takes the pain out of back breaking work - automatic vertebral segmentation and attenuation measurement for opportunistic osteoporosis screening
Timing of inhibitor development in more than 1000 previously untreated patients with severe hemophilia A
Control of Nanomaterial Self-Assembly in Ultrasonically Levitated Droplets
We demonstrate that acoustic trapping can be used to levitate and manipulate droplets of soft matter, in particular, lyotropic mesophases formed from selfassembly of different surfactants and lipids, which can be analyzed in a contact-less manner by X-ray scattering in a controlled gas-phase environment. On the macroscopic length scale, the dimensions and the orientation of the particle are shaped
Rapid NMR Relaxation Rate Measurements Using Optimal Non-Uniform Sampling of Multi-Dimensional Accordion Data Analyzed by a Sparse Reconstruction Method
Nonuniform sampling (NUS) of multidimensional NMR data offers significant time savings while improving spectral resolution or increasing sensitivity per unit time. However, NUS has not been widely used for quantitative analysis because of the nonlinearity of most methods used to model NUS data, which leads to problems in estimating signal intensities, relaxation rate constants, and their error bou
Benefits of Neurohormonal Therapy in Patients With Continuous-Flow Left Ventricular Assist Devices
Left ventricular assist devices (LVADs) have dramatically improved short-term outcomes among patients with advanced heart failure. While neurohormonal blockade (NHB) is the cornerstone of treatment for patients with heart failure with reduced ejection fraction, its effect after LVAD placement has not been established. We reviewed medical records of 307 patients who underwent primary LVAD implantat
Emergency department visits among patients with left ventricular assist devices
Continuous-flow left ventricular assist devices (LVADs) are increasingly implanted to support patients with end-stage heart failure. These patients are at high risk for complications, many of which necessitate emergency care. While rehospitalization rates have been described, there is little data regarding emergency department (ED) visits. We hypothesize that ED visits are frequent and often requi
Management of RVAD Thrombosis in Biventricular HVAD Supported Patients : Case Series
Patients with biventricular assist devices (BIVAD) are severely critically ill compared with patients who receive left ventricular assist device (LVAD) support alone and portend a significant risk for greater adverse events including pump thrombosis (PT). Current approaches to treat PT are limited to LVAD with variable outcomes depending on the management strategy implemented. Moreover the managem
Platelet-derived microparticles regulates thrombin generation via phophatidylserine in abdominal sepsis
Sepsis is associated with dysfunctional coagulation. Recent data suggest that platelets play a role in sepsis by promoting neutrophil accumulation. Herein, we show that cecal ligation and puncture (CLP) triggered systemic inflammation, which is characterized by formation of IL-6 and CXC chemokines as well as neutrophil accumulation in the lung. Platelet depletion decreased neutrophil accumulation,
Uridine triphosphate (UTP) induces profibrotic responses in cardiac fibroblasts by activation of P2Y2 receptors
Cardiac fibroblasts (CFs) play a key role in response to injury and remodeling of the heart. Nucleotide (P2) receptors regulate the heart but limited information is available regarding such receptors in CFs. We thus sought to determine if extracellular nucleotides regulate fibrotic responses (e.g., proliferation, migration and expression of profibrotic markers) of CFs in primary culture. UTP incre
Mild hypothermia does not attenuate platelet aggregation and may even increase ADP-stimulated platelet aggregation after clopidogrel treatment
BACKGROUND: Mild hypothermia is currently standard of care for cardiac arrest patients in many hospitals and a common belief is that hypothermia attenuates platelet aggregation. We wanted to examine the effects of clopidogrel on platelet aggregation during hypothermia.METHODS: Platelet reactivity at 37° C and 33° C was evaluated by light transmission aggregometry and vasodilator-stimulated phospho
Molecular design and synthesis of hydroxide ion exchange membranes carrying alicyclic quaternary ammonium cations
Significantresearch efforts are currently directed towards the synthesis and studies of durable anion exchange membranes (AEMs) with the aim to develop alkaline fuel cells and electrolyzers able to operate efficiently without platinum-groupmetal catalysts [1]. The grand challenge is to identify and synthesize polymeric AEM materials possessingthe necessary chemical and thermal stability. Studies o
Effects of delayed cord clamping on neurodevelopment and infection at four months of age : A randomised trial
Aim To investigate the effect that delayed and early umbilical cord clamping have on neurodevelopment, immunoglobulin G (IgG) and symptoms of infection during the first 4 months of life. Methods Full-term infants (n = 382) were randomised to delayed (≥180 sec) or early cord clamping (≤10 sec). The Ages and Stages Questionnaire (ASQ) was used to assess neurodevelopment at 4 months. Immunoglobulin G
PVL-positiva Staph aureus gav nekrotiserande pneumoni : Beskrivning av tre svära fall hos tidigare friska unga
We describe three cases of community-acquired pneumonia, in which the causative agent was methicillin sensitive S. Aureus positive for Panton-Valentine leukocidin (PVL). The patients were previously healthy children (2 weeks, 12 years and 15 years old). No epidemiologic connection existed, confirmed by spa-typing. Two cases were primary pneumonias with signs of necrosis, and the third case was a p
