Sex-specific lesion pattern of functional outcomes after stroke

Stroke represents a considerable burden of disease for both men and women. However, a growing body of literature suggests clinically relevant sex differences in the underlying causes, presentations and outcomes of acute ischaemic stroke. In a recent study, we reported sex divergences in lesion topographies: specific to women, acute stroke severity was linked to lesions in the left-hemispheric post

Synchrotron XPS and Electrochemical Study of Aging Effect on Passive Film of Ni Alloys

To investigate aging effect on the passive film of Ni23Cr15Mo and Ni22Cr9Mo3Nb, synchrotron-based X-ray photoelectron spectroscopy (XPS) was used to analyze the structure and composition of the air-formed passive film on the alloys. The corrosion resistance of the two Ni alloys in 1 M NaCl solution was evaluated with electrochemical cyclic polarization measurement. The synchrotron XPS measurement

Successful invasions to freshwater systems double with climate warming

Although invasive species are recognized as a major threat to freshwaters, little is known about how future climate warming will affect the success of invaders. Ecosystems are also often simultaneously impacted by multiple, potentially interacting, invading species and the management of species invasions can be incredibly difficult. Sensitive methods such as environmental DNA (eDNA) metabarcoding,

Adverse neonatal outcome and veno-arterial differences in umbilical cord blood pH (ΔpH) at birth : a population-based study of 108,629 newborns

BACKGROUND: Umbilical cord blood gases are routinely used by midwives and obstetricians for quality assurance of birth management and in clinical research. They can form the basis for solving medicolegal issues in the identification of severe intrapartum hypoxia at birth. However, the scientific value of veno-arterial differences in cord blood pH, also known as ΔpH, is largely unknown. By traditio

Examining the causal effect of type 2 diabetes on ischemic heart disease : - a longitudinal study with four measurements (1980-2017)

OBJECTIVE: This longitudinal study examines a possible causal effect between type 2 diabetes and ischemic heart disease (IHD) by using measurements on four occasions from the Swedish Statistics on Income and Living Conditions (SILC) together with nationwide healthcare registers.METHODS: This was a longitudinal study based on a random sample of men and women (n = 2014) from the Swedish population w

Subclinical atherosclerosis and risk factors in relation to autonomic indices in the general population

OBJECTIVE: Orthostatic hypotension and resting heart rate (RHR) are associated with cardiovascular disease (CVD). However, it is unknown how these factors relate to subclinical CVD. We examined the relationship between orthostatic blood pressure (BP) response, RHR and cardiovascular risk factors, including coronary artery calcification score (CACS) and arterial stiffness, in the general population

Comparing α-Synuclein Fibrils Formed in the Absence and Presence of a Model Lipid Membrane : A Small and Wide-Angle X-Ray Scattering Study

Amyloid fibrils are associated with a number of different neurodegenerative diseases. Detailed knowledge of the fibril structure will be of importance in the search of therapy and may guide experiments to understand amyloid formation. In this paper we investigate the morphology of α-synuclein amyloid fibrils, associated with Parkinson’s disease, formed under different conditions. In particular, we

Restorative cell and gene therapies for Parkinson's disease

One of the core pathological features of Parkinson's disease (PD) is the loss of the dopaminergic nigrostriatal pathway which lies at the heart of many of the motor features of this condition as well as some of the cognitive problems. The importance of this pathological event is evident through the clinical benefits that are seen when patients with PD are treated with dopaminergic agents, at least

Dietary fatty acids and endometrial cancer risk within the European Prospective Investigation into Cancer and Nutrition

Background: Diet may impact important risk factors for endometrial cancer such as obesity and inflammation. However, evidence on the role of specific dietary factors is limited. We investigated associations between dietary fatty acids and endometrial cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC). Methods: This analysis includes 1,886 incident endometrial ca

Prostate Specific Antigen and Prostate Cancer in Chinese Men Undergoing Initial Prostate Biopsies Compared with Western Cohorts

Purpose We determined the characteristics of Chinese men undergoing initial prostate biopsy and evaluated the relationship between prostate specific antigen levels and prostate cancer/high grade prostate cancer detection in a large Chinese multicenter cohort. Materials and Methods This retrospective study included 13,904 urology outpatients who had undergone biopsy for the indications of prostate

Sex matters : predator presence induces sexual dimorphism in a monomorphic prey, from stress genes to morphological defences

Inducible defences allow prey to increase survival chances when predators are present while avoiding unnecessary costs in their absence. Many studies report considerable inter-individual variation in inducible defence expression, yet what underlies this variation is poorly understood. A classic vertebrate example of a predator-induced morphological defence is the increased body depth in crucian ca

Activity and segregation behavior of Pd75%Ag25%(1 1 1) during CO oxidation – An in situ NAP-XPS investigation

The surface reactivity during CO oxidation over Pd(1 1 1) and Pd75%Ag25%(1 1 1) single crystals has been investigated using near ambient pressure X-ray photoelectron spectroscopy (NAP-XPS) under excess oxygen conditions (p ≈ 2 mbar, O2:CO=10). The (√6×√6) Pd5O4 surface oxide is present on Pd(1 1 1) when the surface is highly active under the applied conditions. The CO2 formation profile follows a

Nanoscale characterization of collagen structural responses to in situ loading in rat Achilles tendons

The specific viscoelastic mechanical properties of Achilles tendons are highly dependent on the structural characteristics of collagen at and between all hierarchical levels. Research has been conducted on the deformation mechanisms of positional tendons and single fibrils, but knowledge about the coupling between the whole tendon and nanoscale deformation mechanisms of more commonly injured energ
