Fermentation of the Straw Material Paja Brava by the Yeast Pichia stipitis in a Simultaneous Saccharification and Fermentation Process

Paja Brava is a native South American grass with a high carbohydrate content. In the current work, the potential of us- ing this feedstock for ethanol production using a simultaneous saccharification and fermentation (SSF) process with the xylose-fermenting yeast Pichia stipitis (Scheffersomyces stipitis) CBS6054 was investigated. The straw material was subjected to SO2 catalyzed steam pretreatmen

Old and very old adults as witnesses: event memory and metamemory

Older people constitute an important category of eyewitnesses. Episodic memory performance in older persons is poorer than in younger adults, but little research has been made on older persons' metacognitive judgments. Since more persons of advanced age will likely be called upon as witnesses in coming years, it is critical to characterize this population's metacognitive abilities. We compared eve

What can aquatic gastropods tell us about phenotypic plasticity? A review and meta-analysis.

There have been few attempts to synthesise the growing body of literature on phenotypic plasticity to reveal patterns and generalities about the extent and magnitude of plastic responses. Here, we conduct a review and meta-analysis of published literature on phenotypic plasticity in aquatic (marine and freshwater) gastropods, a common system for studying plasticity. We identified 96 studies, using

Modeling of Bottle-Brush Polymer Adsorption onto Mica and Silica Surfaces: Effect of Side-Chain Length

Adsorption of a series of charged bottle-brush polymers with side chains of different length on solid surfaces is modeled using a lattice mean-field theory. The bottle-brush polymers are modeled Lis being composed of two types of main-chain segments: charged segments and uncharged segments with ill attached side chain. The composition variable X denotes the percentage of charged main-chain segment

In situ quantification of minor compounds in pressurized carbon dioxide using Raman spectroscopy

In this work, we present an optical approach that allows quantification of compounds dissolved down to a sub 10 ppm (molar) level in supercritical carbon dioxide (scCO(2)) by in situ Raman spectroscopy. The quantification strategy is based on the consideration of Raman signal intensity ratios and of weak Raman signals of CO2. The first measure makes the quantification strategy independent of the r

M4 Muscarinic Receptor Signaling Ameliorates Striatal Plasticity Deficits in Models of L-DOPA-Induced Dyskinesia.

A balanced interaction between dopaminergic and cholinergic signaling in the striatum is critical to goal-directed behavior. But how this interaction modulates corticostriatal synaptic plasticity underlying learned actions remains unclear-particularly in direct-pathway spiny projection neurons (dSPNs). Our studies show that in dSPNs, endogenous cholinergic signaling through M4 muscarinic receptors

Adolescent Health and Adult Labor Market Outcomes

Whereas a large literature has shown the importance of early life health for adult socioeconomic outcomes, there is little evidence on the importance of adolescent health. We contribute to the literature by studying the impact of adolescent health status on adult labor market outcomes using a unique and large-scale dataset covering almost the entire population of Swedish males. We show that most t

Åldrandet och språket : en språkhistorisk analys av hög ålder och åldrande i Sverige cirka 1875–1975

Popular Abstract in SwedishVad är åldrande? När började man över huvud taget tala om ”åldrande”? När fick ordet ”pensionär” den betydelse vi är vana vid idag? I Åldrandet och språket studeras ord och uttryck för att ringa in vad man har menat med hög ålder och åldrande i Sverige under hundraårsperioden mellan 1875 och 1975. Frågor kring hög ålder och åldrande har stor aktualitet idag. I Sverige ocThis thesis analyses how old age and ageing were manifested and understood in Sweden from approximately 1875 to 1975. It thus aims to provide historical background to current debate about for instance the retirement age and how to best care for the elderly. Encyclopaedia entries from both the beginning and the end of this period describe ageing as a medical process of physical decline. Since much

Gene×dietary pattern interactions in obesity: analysis of up to 68,317 adults of European ancestry.

Obesity is highly heritable. Genetic variants showing robust associations with obesity traits have been identified through genome-wide association studies. We investigated whether a composite score representing healthy diet modifies associations of these variants with obesity traits. 32 BMI- and 14 waist-hip ratio (WHR)-associated SNPs were genotyped and genetic risk scores (GRS) calculated in 18

Accessing microenvironment compartments in formalin-fixed paraffin-embedded tissues by protein expression analysis.

Background: Formalin-fixed paraffin-embedded (FFPE) samples are an outstanding source of new information regarding disease evolvements. Current research on new biomarkers and diseases features has recently invested resources in FFPE-related projects. Results: In order to initiate clinical protein-expression studies using minute amount of biological material, a workflow based on the combination of

Comprehensive counseling about combined hormonal contraceptives changes the choice of contraceptive methods: results of the choice program in Sweden.

Objective. To study the influence of counseling on women's contraceptive decisions. Design. A cross-sectional multicenter study. Setting. 70 Swedish family planning clinics. Population. Women aged 15-40 years attending for a contraceptive consultation who expressed interest in a combined hormonal contraceptive (CHC) method. Methods. Structured counseling about three CHCs and questionnaires complet

Factors Influencing Occupational Engagement in Day Centers for People with Psychiatric Disabilities.

Occupational engagement is a vital factor in people's lives since it has been shown to be important for health and well-being. Community-based day centers (DCs), both meeting place-oriented and work-oriented ones, are common service alternatives in many western countries for enabling engagement in productive and leisure occupations among people with psychiatric disabilities. Little is, however, kn

Zinc is the modulator of the calcium-dependent activation of post-translationally acting thiol-enzymes in autoimmune diseases.

Post-translational modifications of proteins can generate antigenic conformations that may cause autoimmune diseases in persons with specific HLA-haplotypes. Monocytes and macrophages, attracted to an inflamed site, can release post-translationally acting enzymes, such as transglutaminases and peptidylarginine deiminases. In vivo, the activation of these enzymes is crucial for the further course o

Country characteristics and non-indigenous species

This paper presents an econometric test of two hypotheses underlying the occurrence of non-indigenous species (NIS) at the global scale: openness of recipient nations which allows for international trade to act as a vector of NIS, and habitat fragmentation in recipient nations which facilitates establishment of introduced NIS. Explorative econometric methods have been utilised that combine the ana

Genetic analysis shows that Rubus vikensis is a distinct species with a disjunct distribution

Rubus vikensis A. Pedersen ex G. Wendt (sect. Corylifolii) was recently described from a restricted area in north western Scania, Sweden. In this investigation, I show that the same species occurs also on the Onsala peninsula in northern Halland and on a single locality in the middle of Halland. It has 35 chromosomes in all parts of the distribution area. Moreover, I show by random amplified polym
