Antibacterial and antioxidant double-layered nanofibrous mat promotes wound healing in diabetic rats

Diabetic wounds are problematic to heal owing to microbial infections as well as decreased proliferation and high concentrations of reactive oxygen species. In this study, a double-layered nanofibrous mat containing grape seed extract (GSE) and silver sulfadiazine (SSD) was fabricated. A synthetic biodegradable polymer, e.g., polycaprolactone (PCL), and a natural material (i.e., collagen) were emp

Recent decrease of the impact of tropical temperature on the carbon cycle linked to increased precipitation

The atmospheric CO2 growth rate (CGR) variability is largely controlled by tropical temperature fluctuations. The sensitivity of CGR to tropical temperature (γCGRT) has strongly increased since 1960, but here we show that this trend has ceased. Here, we use the long-term CO2 records from Mauna Loa and the South Pole to compute CGR, and show that γCGRT increased by 200% from 1960–1979 to 1979–2000

The new high-pressure hexagonal Laves phase of the YbZn2 compound

The new metastable high-pressure high-temperature synthesized hexagonal Laves phase compound YbZn2 was investigated. The unit cell parameters, low-temperature Sommerfeld coefficient and Debye temperature were determined. X-ray absorption studies and calculations based on dynamical mean-field theory (DMFT) showed the intermediate valence behavior of YbZn2 with mean Yb valence about 2.55. The values

Probing the coverage of nanoparticles by biomimetic membranes through nanoplasmonics

Although promising for biomedicine, the clinical translation of inorganic nanoparticles (NPs) is limited by low biocompatibility and stability in biological fluids. A common strategy to circumvent this drawback consists in disguising the active inorganic core with a lipid bilayer coating, reminiscent of the structure of the cell membrane to redefine the chemical and biological identity of NPs. Whi

The Resection Rate of Synchronously Detected Liver and Lung Metastasis from Colorectal Cancer Is Low-A National Registry-Based Study

Population-based data on the incidence and surgical treatment of patients with colorectal cancer (CRC) and synchronous liver and lung metastases are lacking as are real-life data on the frequency of metastasectomy for both sites and outcomes in this setting. This is a nationwide population-based study of all patients having liver and lung metastases diagnosed within 6 months of CRC between 2008 an

Short- and intermediate-term impact of DTC telemedicine consultations on subsequent healthcare consumption

Aim: The use of direct-to-consumer (DTC) telemedicine consultations in primary healthcare has increased rapidly, in Sweden and internationally. Such consultations may be a low-cost alternative to face-to-face visits, but there is limited evidence on their effects on overall healthcare consumption. The aim of this study was to assess the short- and intermediate-term impact of DTC telemedicine consu

The effect of charcoal production on carbon cycling in African biomes

Using biomass for charcoal production in sub-Saharan Africa (SSA) may change carbon stock dynamics and lead to irreversible changes in the carbon balance, yet we have little understanding of whether these dynamics vary by biome in this region. Currently, charcoal production contributes up to 7% of yearly deforestation in tropical regions, with carbon emissions corresponding to 71.2 million tonnes

Multiple induced abortions–implications for counselling and contraceptive services from a multi-centre cross-sectional study in Sweden

Objectives: To investigate factors associated with multiple induced abortions. Materials and methods: A multi-centre cross-sectional survey among abortion-seeking women (n = 623;14-47y) in Sweden, 2021. ‘Multiple abortions’ was defined as having had ≥2 induced abortions. This group was compared to women with a previous experience of 0-1 induced abortion. Regression analysis was conducted to determ

All-Optical Switching Based on Sub-Bandgap Photoactivation of Charge Trapping in Metal Halide Perovskites

Controllable optical properties are crucial for the application of light-emitting materials in optical devices. In this work, controllable photoluminescence in metal halide perovskite crystals is realized via photoactivation of their defects. It is found that under continuous excitation, the photoluminescence intensity of a CH3NH3PbBr3 crystal can be fully controlled by sub-bandgap energy photon i

Assessing the Costs of Neuropsychiatric Disease in the Systemic Lupus International Collaborating Clinics Cohort Using Multistate Modeling

Objective: To estimate direct and indirect costs associated with neuropsychiatric (NP) events in the Systemic Lupus International Collaborating Clinics inception cohort. Methods: NP events were documented annually using American College of Rheumatology definitions for NP events and attributed to systemic lupus erythematosus (SLE) or non-SLE causes. Patients were stratified into 1 of 3 NP states (n

Altered blood gene expression in the obesity-related type 2 diabetes cluster may be causally involved in lipid metabolism : a Mendelian randomisation study

Aims/hypothesis: The aim of this study was to identify differentially expressed long non-coding RNAs (lncRNAs) and mRNAs in whole blood of people with type 2 diabetes across five different clusters: severe insulin-deficient diabetes (SIDD), severe insulin-resistant diabetes (SIRD), mild obesity-related diabetes (MOD), mild diabetes (MD) and mild diabetes with high HDL-cholesterol (MDH). This was t

Histidine oxidation in lytic polysaccharide monooxygenase

The lytic polysaccharide monooxygenases (LPMOs) comprise a super-family of copper enzymes that boost the depolymerisation of polysaccharides by oxidatively disrupting the glycosidic bonds connecting the sugar units. Industrial use of LPMOs for cellulose depolymerisation has already begun but is still far from reaching its full potential. One issue is that the LPMOs self-oxidise and thereby deactiv

Policy measures to reduce stereotypical representations of older people in long-term care

Older people are stereotypically portrayed in the media at two extremes of a spectrum, either the healthy and happy retiree, or the fragile and sick older person in need of care. Older people living in residential long-term care are particularly portrayed in a homogenous way. Individuals exposed to stereotypical portrayals could develop a distorted view of the realities of older people and later l

Tracing Sustainability in the Long Run : Genuine Savings Estimates 1850 - 2018

We introduce a new database of historical Genuine Savings (GS), an indicator of sustainable development promoted by the World Bank and widely used in contemporary economic research. GS derives from the theoretical work on wealth accounting, and addresses shortcomings in conventional metrics of economic development by incorporating broader measures of saving and investment, including human capital
