Exploring postoperative cognitive dysfunction and delirium in noncardiac surgery using MRI : A systematic review

Surgical patients are at high risk of developing postoperative cognitive dysfunction (POCD) and postoperative delirium (POD). POCD and POD are associated with increased morbidity and mortality and worsening functional outcomes leading to severe socioeconomic consequences for the patient and the society in general. Magnetic resonance imaging (MRI) offers a unique opportunity to study the anatomy an

Variation of carbon contents in eelgrass (Zostera marina) sediments implied from depth profiles

Seagrass meadows are able to store significant amounts of organic carbon in their underlying sediment, but global estimates are uncertain partly owing to spatio-temporal heterogeneity between and within areas and species. In order to provide robust estimates, there is a need to better understand the fate of, and mechanisms behind, organic carbon storage. In this observational study, we analyse a s

Development and Applications of a Laser-Wakefield X-ray Source (updated)

In laser-wakefield acceleration (LWFA), a femtosecond laser pulse is tightly focused in a gas to intensities exceeding 1018 W/cm2 . The laser radiation ionizes the medium and excites a plasma wave that travels behind the laser pulse. Electrons can be trapped in the oscillations in the plasma density, where electric fields of the order of several hundreds of GV/m accelerate them to relativistic ene

Rivaroxaban for secondary stroke prevention in patients with embolic strokes of undetermined source : Design of the NAVIGATE ESUS randomized trial

Background: Embolic strokes of undetermined source comprise up to 20% of ischemic strokes. The stroke recurrence rate is substantial with aspirin, widely used for secondary prevention. The New Approach riVaroxaban Inhibition of Factor Xa in a Global trial versus ASA to prevenT Embolism in Embolic Stroke of Undetermined Source international trial will compare the efficacy and safety of rivaroxaban,

Dynamic changes in DNA methylation during embryonic and postnatal development of an altricial wild bird

DNA methylation could shape phenotypic responses to environmental cues and underlie developmental plasticity. Environmentally induced changes in DNA methylation during development can give rise to stable phenotypic traits and thus affect fitness. In the laboratory, it has been shown that the vertebrate methylome undergoes dynamic reprogramming during development, creating a critical window for env

Checklist for gene/disease-specific variation database curators to enable ethical data management

Databases with variant and phenotype information are essential for advancing research and improving the health and welfare of individuals. These resources require data to be collected, curated, and shared among relevant specialties to maximize impact. The increasing generation of data which must be shared both nationally and globally for maximal effect presents important ethical and privacy concer

Chronic obstructive pulmonary disease. Aspects of smoking, biomarkers and cardiovascular disease.

Chronic obstructive pulmonary disease (COPD) is a common and preventable disease characterized by airflow obstruction and emphysema development. COPD often coexist with cardiovascular disease (CVD) and both diseases have common risk factors i.e. age and smoking and shared features i.e. chronic inflammation. Smoking is of particular interest as it substantially increases the risk of developing COPD

Technical support framework for sustainable management of transboundary water resources

Sustainable management of transboundary rivers, especially in water-scarce regions is increasingly becoming more challenging due to the collective adverse impact of upstream development and climate change on transboundary scale. Two major tributaries of the Tigris River, the Diyala (Sīrvān) and the Lesser Zab River basins, are shared between Iraq and Iran. They were adopted as representative basin

Glycerol esters of butyric and valeric acids counteract diet-related disorders : Prevention of metabolic disturbances induced by high-fat intake

Short-chain fatty acids (SCFAs), gut metabolites formed from indigestible dietary components by the colonic microbiota, are associated with numerous health effects, and may be responsible for the beneficial effects, at least in part, associated with dietary fibre. High-fat diets are known to cause low-grade inflammation in the body, but SCFAs are suggested to counteract unfavourable effects induce

Molecular pathology of the luminal class of urothelial tumors

Molecular subtypes of urothelial carcinoma may be divided into luminal and nonluminal tumors. Nonluminal tumors are composed of cases with basal/squamous-like or small cell/neuroendocrine features, with a consensus on the molecular characteristics of the respective subtype. In contrast, luminal tumors are more disparate with three to five suggested subtypes and with definitions that do not always

A personalized approach to the management of VWD

The goal of treating Von Willebrand Disease (VWD) is to replace deficient or dysfunctional Von Willebrand Factor (VWF) protein. However, the choice of treatment has to be considered carefully in view of patient factors and the unique properties of replacement products. Tailoring a treatment plan to an individual patient's bleeding challenge is an intricate process. This review describes personaliz

Dehydration affects drug transport over nasal mucosa

Formulations for nasal drug delivery often rely on water sorption to adhere to the mucosa, which also causes a higher water gradient over the tissue and subsequent dehydration. The primary aim of this study was therefore to evaluate mucosal response to dehydration and resolve the hypothesis that mucoadhesion achieved through water sorption could also be a constraint for drug absorption via the nas

Re-sensitization of desensitized histamine H1 receptors in the human skin takes more than 18 hours

Background: It is known since the time of testing histamine on pieces of guinea pig's jejunum that histamine receptors can develop insensitivity. The aim was to find evidence for desensitization of histamine H1 receptors in the human skin in vivo and, if found, to study the time for such receptors to regain normal sensitivity. Materials and Methods: A skin prick test with histamine (10 mg mL–1) wa
