Antioxidants from plants protect against skin photoaging

Exposure to UV light triggers the rapid generation and accumulation of reactive oxygen species (ROS) in skin cells, with consequent increase in oxidative stress and thus in photoaging. Exogenous supplementation with dietary antioxidants and/or skin pretreatment with antioxidant-based lotions before sun exposure might be a winning strategy against age-related skin pathologies. In this context, plan

Development of hydrophilic membranes for challenging separation applications

Membrane fouling and its control is one of the most critical parameters in the application of membrane processes. The degree of fouling depends on the application and on industrial scale, fouling is often observed as reduction in plant capacity over time. One approach to reduce fouling for the pressure driven processes microfiltration and ultrafiltration is to use hydrophilic membranes. This paper

Membrane processes in the separation and utilisation of wood biomass in the context of the pulp and paper industry

The recent developments in the field of biorefineries open new opportunities for the pulp and paper industry to diverse from classical carton and paper production to bio-based chemicals. The trend is thus to use the three key wood components hemicelluloses, lignin and cellulose as raw materials for production of a wide range of biochemicals. A key success factor is the integration of energy-effici

Exercise benefits in cardiovascular disease : beyond attenuation of traditional risk factors

Despite strong scientific evidence supporting the benefits of regular exercise for the prevention and management of cardiovascular disease (CVD), physical inactivity is highly prevalent worldwide. In addition to merely changing well-known risk factors for systemic CVD, regular exercise can also improve cardiovascular health through non-traditional mechanisms. Understanding the pathways through whi

Membrane opportunities in production and water loop of biorefineries based on lignocellulosic biomass

In recent years biorefineries using lignocellulosic biomass such as wood and agricultural residuals as raw material have gained significant interest since they avoid competition with food production. One of the key development areas of these lignocellulosic based biorefinery concepts is the integration low energy and high selective separation processes. Thus, membrane processes either as stand-alo

Membrane applications for bulk fermentation processes: From antibiotics to biochemicals

1. IntroductionThe third wave of biotechnology – white biotechnology – started with the end of the 20th century with the goal to replace conventional chemical processes based on C2/C3 chemistry by biotechnological processes. In biotechnology fermentation is used as standard conversion process for the production of bulk fermentation products such as antibiotics, enzymes, bioethanol and organic acid

The Situation of Safe Surgery and Anaesthesia in Tanzania : A Systematic Review

Background: Improvement in the surgical system requires intersectoral coordination. To achieve this, the development of National Surgical, Obstetric, and Anaesthesia Plans (NSOAPS) has been recommended. One of the first steps of NSOAP development is situational analysis. On the ground situational analyses can be resource intensive and often duplicative. In 2016, the Ministry of Health of Tanzania

Improving narrative writing skills through observational learning: A study of Swedish 5th-grade students

Observational learning is a successful method for improving writing skills in various genres. We explore effects of a five lesson intervention series based on peer observation. Fifty-five Swedish 5th-grade students aged 10-12 years followed this intervention program. The language and reading comprehension and working memory capacity were tested. The students watched short film-clips with peers wor

Minimal residual disease assessed with deep sequencing of NPM1 mutations predicts relapse after allogeneic stem cell transplant in AML

Mutations in NPM1 can be used for minimal residual disease (MRD) analysis in acute myeloid leukemia (AML). We here applied a newly introduced method, deep sequencing, allowing for simultaneous analysis of all recurrent NPM1 insertions and thus constituting an attractive alternative to multiple PCRs for the clinical laboratory. We retrospectively used deep sequencing for measurement of MRD pre- and

34th EMS Summer School : Membranes in Biorefineries

The EMS Summer School “Membranes in Biorefineries” is related to Annex XVII of the Industrial Energy Related Technologies and Systems (IETS)Implementing Agreement: “Membrane Filtration for Energy-efficient Separation of Lignocellulosic Biomass Components” co-ordinated by the Department of Chemical Engineering at Lund University, Sweden.The IETS Implementing Agreement is an initiative within IEA (I

Precambrian mafic dyke swarms in the Singhbhum craton (eastern India) and their links with dyke swarms of the eastern Dharwar craton (southern India)

Based on trend, cross-cutting relationships and U-Pb dating, Precambrian mafic dykes in the Singhbhum craton, earlier collectively identified as ‘Newer Dolerite Swarm’ have been separated into seven distinct swarms, which are thought to be the plumbing systems for Large Igneous Provinces (LIPs). These Singhbhum swarms range in age from ∼2.80 Ga to ∼1.76 Ga, and include the ∼2.80 Ga NE-SW trending

Consciousness assessment : A questionnaire of current neuroscience nursing practice in Europe

Aims and objectives: To study practice in consciousness assessment among neuroscience nurses in Europe. Background: Over the years, several instruments have been developed to assess the level of consciousness for patients with brain injury. It is unclear which instrument is being used by nurses in Europe and how they are trained to use these tools adequately. Design/methods: A cross-sectional ques
