Differential DNA methylation of the genes for amyloid precursor protein, tau, and neurofilaments in human traumatic brain injury

Traumatic brain injury (TBI) is an established risk factor for neurodegenerative disorders and dementias. Epigenetic modifications, such as DNA methylation, may alter the expression of genes without altering the DNA sequence in response to environmental factors. We hypothesized that DNA methylation changes may occur in the injured human brain and be implicated in the neurodegenerative aftermath of

Pegylated bis-indolyl polyurethane dendrimer : Empty drug carrier with prominent anticancer activity

Blocked isocyanate-terminated, bioactive bis-indole based polyurethane dendrimers of generation G0 – G3 were subjected to urethane interchange reaction with poly(ethylene glycol) monomethyl ether; the reactions yielded corresponding PEGylated dendrimers. The structures of the PEGylated dendrimers were confirmed using spectroscopic and SEC-MALS techniques. The PDI of the polymers were found between

Asteroid break-ups and meteorite delivery to Earth the past 500 million years

The meteoritic material falling on Earth is believed to derive from large break-up or cratering events in the asteroid belt. The flux of extraterrestrial material would then vary in accordance with the timing of such asteroid family-forming events. In order to validate this, we investigated marine sediments representing 15 time-windows in the Phanerozoic for content of micrometeoritic relict chrom

Hydrogen bond effects in multimode nuclear dynamics of acetic acid observed via resonant x-ray scattering

A theoretical and experimental study of the gas phase and liquid acetic acid based on resonant inelastic x-ray scattering (RIXS) spectroscopy is presented. We combine and compare different levels of theory for an isolated molecule for a comprehensive analysis, including electronic and vibrational degrees of freedom. The excitation energy scan over the oxygen K-edge absorption reveals nuclear dynam

Regional CO2 inversions with LUMIA, the Lund University modular inversion algorithm, v1.0

Atmospheric inversions are used to derive constraints on the net sources and sinks of CO2 and other stable atmospheric tracers from their observed concentrations. The resolution and accuracy that the fluxes can be estimated with depends, among other factors, on the quality and density of the observational coverage, on the precision and accuracy of the transport model used by the inversion to relat

Acute sore throat and Fusobacterium necrophorum in primary healthcare : A systematic review and meta-analysis

Purpose The main objective of this review was to describe and quantify the association between Fusobacterium necrophorum (FN) and acute sore throat in primary healthcare (PHC). Methods In this systematic review and meta-analysis, we searched Scopus and PubMed for case-control studies reporting the prevalence of FN in patients attending primary care for an uncomplicated acute sore throat as well as

From Face-to-Face to Online UDeL Camps : Supporting Staff at Higher Education Institutions in Developing Universal Design for eLearning (UDeL)

The TINEL Project is running a series of camps for staff at higher education institution to support them in developing inclusive eLearning. The first camp was conducted face-to-face, but the coronavirus pandemic meant that the second camp was conducted online. This created a case study in inclusive eLearning in itself and allowed us to experience and reflect on the challenges and opportunities of

Implementing a sectional scheme for early aerosol growth from new particle formation in the Norwegian Earth System Model v2 : Comparison to observations and climate impacts

Aerosol-cloud interactions contribute to a large portion of the spread in estimates of climate forcing, climate sensitivity and future projections. An important part of this uncertainty is how much new particle formation (NPF) contributes to cloud condensation nuclei (CCN) and, furthermore, how this changes with changes in anthropogenic emissions. Incorporating NPF and early growth in Earth system

Comment on “Individual heterozygosity predicts translocation success in threatened desert tortoises”

Scott et al. (Reports, 27 November 2020, p. 1086) bring much-needed attention to species conservation by demonstrating heterozygote superiority among translocated tortoises. However, we believe that their recommended heterozygosity decision rule risks taking conservation genomics backward. We argue that their advice could misguide conservation management aimed at establishing viable populations, a

Background paper : 20th Informal ASEM Seminar on Human Rights (ASEMHRS20) Human Rights of Older Persons 22-24 February 2021 Virtual/Seoul, Republic of Korea

This background paper provides an overview of the fundamental concepts and some of the important current issues relating to the human rights of older persons at the international, regional and national levels. The COVID-19 pandemic has brought into high relief social attitudes and institutional practices that existed before the pandemic that embody ageist assumptions and result in the denial of eq

Improvement of modeling plant responses to low soil moisture in JULESvn4.9 and evaluation against flux tower measurements

Drought is predicted to increase in the future due to climate change, bringing with it myriad impacts on ecosystems. Plants respond to drier soils by reducing stomatal conductance in order to conserve water and avoid hydraulic damage. Despite the importance of plant drought responses for the global carbon cycle and local and regional climate feedbacks, land surface models are unable to capture obs

Biomarkers after Controlled Inhalation Exposure to Exhaust from Hydrogenated Vegetable Oil (HVO)

Hydrogenated vegetable oil (HVO) is a renewable diesel fuel used to replace petroleum diesel. The organic compounds in HVO are poorly characterized; therefore, toxicological properties could be different from petroleum diesel exhaust. The aim of this study was to evaluate the exposure and effective biomarkers in 18 individuals after short-term (3 h) exposure to HVO exhaust and petroleum diesel exh

How unnecessarily high abatement costs and unresolved distributional issues undermine nutrient reductions to the Baltic Sea

This paper systematically reviews the literature on how to reduce nutrient emissions to the Baltic Sea cost-effectively and considerations for allocating these costs fairly among countries. The literature shows conclusively that the reduction targets of the Baltic Sea Action Plan (BSAP) could be achieved at considerably lower cost, if countries would cooperate to implement the least costly abateme

“In a Way We Took the Hospital Home”—A Descriptive Mixed-Methods Study of Parents’ Usage and Experiences of eHealth for Self-Management after Hospital Discharge Due to Pediatric Surgery or Preterm Birth

The costly and complex needs for children with long-term illness are challenging. Safe eHealth communication is warranted to facilitate health improvement and care services. This mixed-methods study aimed to describe parents’ usage and experiences of communicating with professionals during hospital-to-home-transition after their child’s preterm birth or surgery for col-orectal malformations, using

Strengthening the policy framework to resolve lax implementation of the Baltic Sea Action Plan for agriculture

In this perspective article, we provide recommendations for strengthening the policy framework for protecting the Baltic Sea from agricultural nutrient pollution. The most striking weakness is the lax implementation of prescribed abatement measures, particularly concerning manure management, in most countries. Institutions of the EU should also be leveraged for achieving Baltic Sea Action Plan (BS

Integration of remote sensing and Mexican water quality monitoring system using an extreme learning machine

Remote Sensing, as a driver for water management decisions, needs further integration with monitoring water quality programs, especially in developing countries. Moreover, usage of remote sensing approaches has not been broadly applied in monitoring routines. Therefore, it is necessary to assess the efficacy of available sensors to complement the often limited field measurements from such programs

Chemical and biochemical bleaching of oat hulls : The effect of hydrogen peroxide, laccase, xylanase and sonication on optical properties and chemical composition

Oat hulls are an excellent dietary fibre source for food supplements due to their rich lignocellulose composition as well as their great abundance as low-value agricultural side stream. For the production of white fibre supplements, a mild, but effective bleaching of the hulls is required. Chemical bleaching with hydrogen peroxide and sodium hydroxide was here found to be a suitable method increas
