A stable liquid-liquid extraction system for clavulanic acid using polymer-based aqueous two-phase systems
The partitioning of Clavulanic Acid (CA) in a novel inexpensive and stable aqueous two-phase system (ATPS) composed by poly(ethylene glycol) (PEG) and sodium polyacrylate (NaPA) has been studied. The aqueous two-phase systems are formed by mixing both polymers with a salt (NaCl or Na2SO4) and an aqueous solution of CA. The stability of CA on the presence of both polymers was investigated and it wa
Active CFTR channels are important for insulin- and glucagon secretion
The visual ecology of a deep-sea fish, the escolar Lepidocybium flavobrunneum (Smith, 1843).
Escolar (Lepidocybium flavobrunneum, family Gempylidae) are large and darkly coloured deep-sea predatory fish found in the cold depths (more than 200 m) during the day and in warm surface waters at night. They have large eyes and an overall low density of retinal ganglion cells that endow them with a very high optical sensitivity. Escolar have banked retinae comprising six to eight layers of rods
The linkages between photosynthesis, productivity, growth and biomass in lowland Amazonian forests
Understanding the relationship between photosynthesis, net primary productivity and growth in forest ecosystems is key to understanding how these ecosystems will respond to global anthropogenic change, yet the linkages among these components are rarely explored in detail. We provide the first comprehensive description of the productivity, respiration and carbon allocation of contrasting lowland Am
TCF7L2-conferred apoptosis in pancreatic beta cells involves the p53 pathway
Distinct transcriptional control in major immunogenetic subsets of chronic lymphocytic leukemia exhibiting subset-biased global DNA methylation profiles
Chronic lymphocytic leukemia (CLL) can be divided into prognostic subgroups based on the IGHV gene mutational status, and is further characterized by multiple subsets of cases with quasi-identical or stereotyped B cell receptors that also share clinical and biological features. We recently reported differential DNA methylation profiles in IGHV-mutated and IGHV-unmutated CLL subgroups. For the firs
The Genetics of Autism Spectrum Disorders and Related Neuropsychiatric Disorders in Childhood.
Objective: Autism spectrum disorders are considered to be among the most heritable mental disorders, a notion based on surprisingly sparse data from small clinical studies. Population-based studies of the heritability of other neuro-psychiatric disorders and comorbidities among them have also been sparse. The authors sought to address both of these issues. Method: Parents of all Swedish 9- and 12-
Allocation to pollen competitive ability versus seed production in Viola tricolor as an effect of plant size, soil nutrients and presence of a root competitor
In hermaphroditic plants, the effect of a social environment on sex allocation has not been studied to our knowledge, while in hermaphroditic animals such effects are known to be common. In recent years, studies on root competition beyond the effects of nutrients have shown that plants can respond to their conspecific root competitors (social environment), making it interesting to ask if these eff
High temperature simultaneous saccharification and fermentation of starch from inedible wild cassava (Manihot glaziovii) to bioethanol using Caloramator boliviensis.
The thermoanaerobe, Caloramator boliviensis was used to ferment starch hydrolysate from inedible wild cassava to ethanol at 60°C. A raw starch degrading α-amylase was used to hydrolyse the cassava starch. During fermentation, the organism released CO2 and H2 gases, and Gas Endeavour System was successfully used for monitoring and recording formation of these gaseous products. The bioethanol produc
Key issues in European food science research: a review of the European Food Science Day 2009
This paper is a report on the European Food Science Day (Brussels, 18 November 2009, organized by the CommNet network of food science communicators) and its outcomes. The article presents FP 7 as a key funding mechanism in European food and nutrition research and it puts research in this sector in a socio-economic context. The article then reviews the specific activities of several EU-funded proje
Is choice of care compatible with integrated health care? An exploratory study in Sweden
Competitive and integrative policy actions are simultaneously being promoted in Swedish primary care; citizens' choice of care is launched while primary care is expected to integrate its activities with other providers for the creation of local health care. Competition tends, however, to fragment the provision of services. The aim of this study is, accordingly, to explore whether or not these poli
Accurate measurements of laminar burning velocity using the Heat Flux method and thermographic phosphor technique
The Heat Flux method was further developed to significantly reduce its experimental uncertainty and used to determine burning velocities under conditions when the net heat loss from the flame to the burner is zero. Non-stretched flames were stabilized on a perforated plate burner at 1 atm. Measurements of the adiabatic burning velocity of methane air flames at initial mixture temperatures of 318 K
Correlations for saturated critical heat flux in microchannels
Experimental results of the saturated-flow boiling critical heat flux (CHF) in microchannels for both multi- and single-channel configurations were obtained from the literature. The collected database contains 629 data points, covering five halogenated refrigerants, nitrogen, and water, for a wide range of operational conditions, and different microchannel dimensions. The whole database was analyz
Regional Stress-Induced Ischemia in Non-fibrotic Hypertrophied Myocardium in Young HCM Patients.
The relationship between hypertrophy, perfusion abnormalities and fibrosis is unknown in young patients with hypertrophic cardiomyopathy (HCM). Since mounting evidence suggests causal relationship between myocardial ischemia and major adverse cardiac events, we sought to investigate whether (1) regional myocardial perfusion is decreased in young HCM patients and in individuals at risk of HCM, and
Comparative Study of Immune Status to Infectious Agents in Elderly Patients with Multiple Myeloma, Waldenstrom's Macroglobulinemia, and Monoclonal Gammopathy of Undetermined Significance
Whereas patients with multiple myeloma (MM) have a well-documented susceptibility to infections, this has been less studied in other B-cell disorders, such as Waldenstrom's macroglobulinemia (WM) and monoclonal gammopathy of undetermined significance (MGUS). We investigated the humoral immunity to 24 different pathogens in elderly patients with MM (n = 25), WM (n = 16), and MGUS (n = 18) and in ag
Linked for action? An analysis of transnational municipal climate networks in Germany
In times of ongoing urbanisation and unabated climate change, cities face increasing demands for improvements in urban climate change governance. This article investigates the activities of transnational municipal networks that were set up in response to climate change and analyses their potential to influence local climate governance. On the basis of a conceptualisation of transnational municipal
Augmented Heat Transfer of an Internal Blade Tip by Full or Partial Arrays of Pin-Fins
Cooling methods are needed for the turbine blade tips to ensure a long durability and safe operation. A common way to cool the tip is to design serpentine passages with 180-deg turn under the blade tip-cap taking advantage of the three-dimensional turning effect and impingement like flow. Improved internal convective cooling is therefore required to increase the blade tip life. In the present stud
Assessment of primary cancers in GH-treated adult hypopituitary patients: an analysis from the Hypopituitary Control and Complications Study
Objective: GH and IGFs have mitogenic properties, causing speculation that GH treatment could increase risk of malignancy. While studies in GH-treated childhood cancer survivors have suggested a slight increase in second neoplasms, studies in GH-treated adults have been equivocal. Design: Incidence of de novo and second cancers was evaluated in 6840 GH-treated and 940 non GH-treated adult patients
