Excitation and contraction of cardiac muscle and coronary arteries of brain-dead pigs

Excitability and contraction of cardiac muscle from brain-dead donors critically influence the success of heart transplantation. Membrane physiology, Ca2+-handling, and force production of cardiac muscle and the contractile properties of coronary arteries were studied in hearts of brain-dead pigs. Cardiac muscle and vascular function after 12 h brain death (decapitation between C2 and C3) were com

Utilising phase diagram to understand barley starch microsphere preparation in an aqueous two-phase system

In this work, a waxy barley starch-PEG aqueous two-phase system (ATPS) phase diagram was constructed, and starch microsphere preparation was explored at different phase diagram positions. The aim was to investigate starch-PEG ATPS phase behaviour and relate this to starch crystallisation and microsphere formation. The hypothesis was that phase diagram position would influence the starch microspher

High variability in tuberculosis treatment outcomes across 15 health facilities in a semi-urban area in central Ethiopia

Background: Despite reported tuberculosis (TB) treatment success rate of 86%, TB remains a leading cause of death in Ethiopia. We investigated patient and provider-specific factors associated with unfavorable treatment outcomes in Ethiopian health facilities providing TB care. Methods: Data on characteristics and treatment outcomes of patients registered for TB treatment at 15 public health facili

Combined anti-C1-INH and radiotherapy against glioblastoma

Background: A more effective immune response against glioblastoma is needed in order to achieve better tumor control. Radiotherapy can induce anti-tumor mediated immune reactions, in addition to its dose response effects. The complement system can function as a bridge between innate and adaptive immune responses. Combining radiotherapy and complement activating therapy is theoretically interesting

Multi-centre, randomised, open-label, blinded endpoint assessed, trial of corticosteroids plus intravenous immunoglobulin (IVIG) and aspirin, versus IVIG and aspirin for prevention of coronary artery aneurysms (CAA) in Kawasaki disease (KD) : the KD CAA prevention (KD-CAAP) trial protocol

Background: Kawasaki disease (KD) is an acute self-limiting inflammatory vasculitis affecting predominantly medium-sized arteries, particularly the coronary arteries. A number of recent studies conducted in different European countries have demonstrated alarmingly high coronary complications despite treatment with intravenous immunoglobulin (IVIG). These high complication rates now emphasize the n

Reliability of using vegetation optical depth for estimating decadal and interannual carbon dynamics

Vegetation optical depth (VOD) from satellite passive microwave sensors has enabled monitoring of aboveground biomass carbon dynamics by building a relationship with static carbon maps over space and then applying this relationship to VOD time series. However, uncertainty in this relationship arises from changes in water stress, as VOD is mainly determined by vegetation water content, which varies

Does lower educational attainment increase the risk of osteoarthritis surgery? a Swedish twin study

Background: Previous studies have reported an inverse association between educational attainment and different osteoarthritis (OA) outcomes. However, none of the previous studies have accounted for potential confounding by early-life environment and genetics. Thus, we aimed to examine the association between educational attainment and knee and hip OA surgery using twin data. Methods: From the Swed

Fundamental energy cost of finite-time parallelizable computing

The fundamental energy cost of irreversible computing is given by the Landauer bound of kTln 2 /bit, where k is the Boltzmann constant and T is the temperature in Kelvin. However, this limit is only achievable for infinite-time processes. We here determine the fundamental energy cost of finite-time parallelizable computing within the framework of nonequilibrium thermodynamics. We apply these resul

Impact of cracks on distribution of chloride-induced reinforcement corrosion

Surface crack width is regulated in codes to limit corrosion of reinforcement bars in concrete. However, the influence of surface crack width on corrosion damages is not directly inferable from previous research.In this work, data on corroded cracked concrete specimens in chloride environments was compiled. Detailed information was included, such as crack and pit locations, local corrosion pattern

The contributions of injury deaths to the gender gap in life expectancy and life disparity in Eastern Mediterranean Region

Background: Injury deaths constitute a major avoidable cause of death affecting life expectancy to a different degree in men and women. This study quantified the contributions of injury deaths to the gender gap in life expectancy (GGLE) and life disparity (GGLD) in nine Eastern Mediterranean Region (EMR) countries. Methods: We retrieved annual data on age-sex specific causes of death from the Worl

Extraction and trapping of truffle flavoring compounds into food matrices using supercritical CO2

A supercritical fluid extraction methodology was used to extract flavoring and bioactive compounds from truffles. Some parameters such as CO2 flow rate (1–3 mg/mL), extraction time (15–90 min) and different trapping food matrices (grape seed oil, gelatin, agar agar and water) were optimized using response surface methodology to enhance extraction and trapping yields. The optimal conditions (2.27 m

Novel oral anticoagulant use in adults with congenital heart disease : a single-center experience report

Background: Adults with congenital heart disease (ACHD) are a group with an increased risk of thromboembolic complications and arrhythmias. Vitamin K antagonists are the most commonly used thromboprophylaxis therapy in this population. Studies on the efficacy and safety of novel oral anticoagulants (NOAC) are scare in ACHD. A retrospective study on ACHD patients on NOAC treatment registered in the

The democratic potential of politically and socially oriented CSOs : The case of North Macedonia

The chapter investigates the democratic potential of politically and socially oriented civil society organizations (CSOs) to engage citizens and articulate citizens’ interests in the policymaking process in North Macedonia. To do so, the chapter reports on the responses of CSOs to a survey which sought information on the extent to which organizations involve members in organizational activities an

Study of the Interfacial Oxidation of InP Quantum Dots Synthesized from Tris(dimethylamino)phosphine

InP quantum dots (QDs) are the most competitive in terms of environmentally friendly QDs. However, the synthesis of InP QDs requires breakthroughs in low-cost and safe phosphorus precursors such as tri(dimethylamino)phosphine [(DMA)3P]. It is found that even if the oxygen is completely avoided, there are still oxidation state defects at the core/shell interface of InP QDs. Herein, the record-break

Deep learning can yield clinically useful right ventricular segmentations faster than fully manual analysis

Right ventricular (RV) volumes are commonly obtained through time-consuming manual delineations of cardiac magnetic resonance (CMR) images. Deep learning-based methods can generate RV delineations, but few studies have assessed their ability to accelerate clinical practice. Therefore, we aimed to develop a clinical pipeline for deep learning-based RV delineations and validate its ability to reduce

Re-evaluation of the impact of BUD21 deletion on xylose utilization by Saccharomyces cerevisiae

Various rational metabolic engineering and random approaches have been applied to introduce and improve xylose utilization and ethanol productivity by Saccharomyces cerevisiae. Among them, the BUD21 gene was identified as an interesting candidate for enhancing xylose consumption as its deletion appeared to be sufficient to improve growth, substrate utilization and ethanol productivity on xylose, e

Long-term residential exposure to source-specific particulate matter and incidence of diabetes mellitus — A cohort study in northern Sweden

Diabetes mellitus (DM) incidence have been assessed in connection with air pollution exposure in several studies; however, few have investigated associations with source-specific local emissions. This study aims to estimate the risk of DM incidence associated with source-specific air pollution in a Swedish cohort with relatively low exposure. Individuals in the Västerbotten intervention programme

Mid-Norian to Hettangian record and time-specific oolites during the end-Triassic Mass Extinction at Wadi Milaha, Musandam Peninsula, United Arab Emirates

The end-Triassic Mass Extinction (ETME) is generally regarded as a consequence of the environmental changes associated with the emplacement of the Central Atlantic Magmatic Province (CAMP) and ranks among the ‘big five’ mass extinctions in Earth history. A notable feature of the ETME is a halt in marine carbonate deposition followed by the formation of unusual facies such as carbonate cement fans
