Electrochemical reactions like water-splitting or corrosion initiate at electrode-electrolyte interface, and in some cases can also be closely linked. In particular, the oxygen evolution reaction (OER) in electrolyzers and the oxygen reduction reaction (ORR) in fuel cells are not only sluggish but can also lead to severe catalyst degradation. A fundamental understanding of these processes is there

The activity and stability of an electrocatalyst is governed by the structural and chemical changes occurring at the solid–liquid interface. While single crystal electrodes have often served as model systems to elucidate structure–function relationships, extending these insights to more realistic polycrystalline electrodes requires experimental techniques with spatial resolution that can operate u

Using ultra-broadband transient terahertz (THz) spectroscopy, complemented by transient absorption (TA) and photoluminescence (PL) measurements, we directly track the generation and relaxation of photoexcited hot carriers, as well as the ultrafast formation of excitons in the transition metal phosphorus trichalcogenide NiPS3, with a temporal resolution of sub-100 fs. A subset of excitons exhibits

A computational method to simulate bimolecular quenching reactions using coarse-grained reaction-diffusion dynamics is presented and applied to the quenching of molecular photosensitizers in solution. The simulations describe photoinduced reactions involving explicit excited states of light-harvesting species together with intrinsic deactivation, as well as collision quenching from separate quench

Synthetic biomaterials used as bone graft extenders (BGE) in spinal fusion surgery can supplement but do not replace autologous bone. This pilot study evaluated a calcium sulfate/hydroxyapatite (CaS/HA) material as an antibiotic-eluting BGE and a carrier for bone morphogenetic protein-2 (BMP-2) in a rabbit posterolateral lumbar (L4–L5) spinal fusion model (PLF). Pre-set CaS/HA beads were loaded wi

From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-ba

Cell therapy for Parkinson's disease (PD) is aimed to replace the degenerated midbrain dopamine (mDA) neurons and restore DA neurotransmission in the denervated forebrain targets. A limitation of the intrastriatal grafting approach, which is currently used in clinical trials, is that the mDA neurons are implanted into the target area, in most cases the putamen, and not in the ventral midbrain wher

Insulin-like growth factor-I (IGF-I) and its binding proteins (BPs) have been associated with breast cancer risk, especially high IGF-I concentrations and the biologically active fraction estimated as the IGF-I/IGFBP-3 molar ratio. The relation of circulating IGF-I and IGFBP-3 concentrations with risk of breast cancer recurrence has been less documented. In addition a new member to a sub-group of

BackgroundAlterations in levels of circulating micro-RNAs might reflect within organ signaling or subclinical tissue injury that is linked to risk of diabetes and cardiovascular risk. We previously found that serum levels of miR-483-5p is correlated with cardiometabolic risk factors and incidence of cardiometabolic disease in a case–control sample from the populations-based Malmö Diet and Cancer S

Objective: The objective is to systematically review the literature on economic evaluations of the interventions for the management of dementia and Alzheimer patients in home, hospital or institutional care. Methods: A systematic search of published economic evaluation studies in English was conducted using specified key words in relevant databased and websites. Data extracted included methods and

SPINK1+/ETS- prostate cancer is an aggressive disease with poor clinical outcome. New data suggest a novel treatment by upregulating the expression of miR-338-5p/-421 through epigenetic modulation or by miRNA replacement. This is a new and interesting concept that warrants further exploration in clinical trials.See related article by Bhatia et al., p. 2755.

Background: Change in the prevalence of raised blood pressure could be due to both shifts in the entire distribution of blood pressure (representing the combined effects of public health interventions and secular trends) and changes in its high-blood-pressure tail (representing successful clinical interventions to control blood pressure in the hypertensive population). Our aim was to quantify the

Introduction: Lung cancer, a common malignancy and cause of cancer-related deaths, is strongly linked to several environmental exposures, and thus primarily affects the elderly. Formerly a man's disease, its incidence is rising among women, and lung cancer is now more common in women than men in Sweden. Women are particularly over-represented among young patients. While overall cancer mortality in

Background: The rising prevalence of dementia represents an important public health issue. There is currently no available cure for dementia disorders, only symptom-relieving therapies which can be either pharmacological or non-pharmacological. The number of non-pharmacological interventions for patients with dementia disorders and their caregivers have been increasing in recent years without much

III-V nanowires have tunable dimensions, between 40 nm and 100 nm in diameter and between 1 and 15 μm in length. Due to their small diameter, they are ideal candidates to interact with cells without detrimental effects on the cell viability. Nanowires can be used as sensors: in our case, we have shown that arrays of vertical gallium phosphide nanowires are promising materials for biosensing in mem

The iron carbene complex [FeII(btz)3](PF6)2 (where btz = 3,3′-dimethyl-1,1′-bis(p-Tolyl)-4,4′-bis(1,2,3-Triazol-5-ylidene)) has been synthesized, isolated, and characterized as a low-spin ferrous complex. It exhibits strong metal-To-ligand charge transfer (MLCT) absorption bands throughout the visible spectrum, and excitation of these bands gives rise to a 3MLCT state with a 528 ps excited-state l

Chronic Obstructive Pulmonary Disease (COPD) is often caused by smoking and other stressors. This causes oxidative stress, which induces numerous changes on both the transcriptome and proteome of the cell. We aimed to examine if the endomembrane pathway, including the endoplasmic reticulum (ER), Golgi, and lysosomes, was disrupted in fibroblasts from COPD patients as opposed to healthy ever-smoker

Background: While patient performance after participating in cardiac rehabilitation programmes after acute myocardial infarction is regularly reported through registry and survey data, information on cardiac rehabilitation programme characteristics is less well described. Aim: The aim of this study was to evaluate Swedish cardiac rehabilitation programme characteristics and adherence to European G

Objective: To estimate the prevalence and incidence of non-gout crystal arthropathy in relation to socioeconomic factors in southern Sweden. Methods: All patients (age ≥ 18 years) with at least one visit to a physician with the diagnosis of interest in the Skåne region (population of 1.3 million) in 1998-2014 were identified. Non-gout crystal arthropathy (ICD-10 codes M11.0-M11.9) was subclassifie
