Fluorogenic affinity gels constructed from clickable boronic acids

Boronate affinity gel was prepared by immobilizing azide-functionalized boronic acid on alkyne-modified Sepharose. Different azide-functionalized boronic acids were synthesized from 2-, 3-, and 4-aminophenylboronic acids. One of the azide-functionalized boronic acids, 3BII, displayed weak and unexpected fluorescence emission. Using Cu(I)-catalyzed 1,3-dipolar azide-alkyne cycloaddition (CuAAC) rea

Picosecond excitation for reduction of photolytic effects in two-photon laser-induced fluorescence of CO

Two-photon laser-induced fluorescence for detection of carbon monoxide (CO) frequently shows interferences by emission from photolytically produced C-2 radicals encountered under fuel-rich combustion conditions. Reduced C-2 interference for excitation with laser pulses in the picosecond regime is here demonstrated by comparison with excitation using nanosecond pulses for measurements in laminar pr

Synthesis, Molecular Structure, and Chiroptical Properties of Dibenzylidene Derivatives of Bicyclo[3.3.1]nonane and Brexane.

Synthesis of several enantiomerically pure unsaturated bicyclo[3.3.1]nonane and related brexane (tricyclo[4.3.0.0(3,7) ]nonane) derivatives bearing exocyclic benzylidene substituents from readily available (+)-(1S,5S)-bicyclo[3.3.1]nonane-2,6-dione was accomplished. Molecular geometry and chiroptical properties of compounds with enone and styrene chromophores were studied by X-ray diffraction anal

From homothally to heterothally; mating preferences and genetic variation within clones of the dinoflagellate Gymnodinium catenatum

The chain-forming dinoflagellate Gymnodinium catenatum Graham is responsible for outbreaks of paralytic shellfish poisoning (PSP), a human health threat in coastal waters. Sexuality in this species is of great importance in its bloom dynamics, and has been shown to be very complex but lacks an explanation. For this reason, we tested if unreported homothallic behavior and rapid genetic changes may

Miniaturization of multiplexed planar recombinant antibody arrays for serum protein profiling.

Background: Antibody-based microarrays are a developing tool for high-throughput proteomics in health and disease. However, in order to enable global proteome profiling, novel miniaturized high-density antibody array formats must be developed. Results: In this proof-of-concept study, we have designed a miniaturized planar recombinant (single-chain Fragment variable). antibody array technology plat

Range limits, large-scale biogeographic variation, and localized evolutionary dynamics in a polymorphic damselfly

Studies of heritable colour polymorphisms allow investigators to track the genetic dynamics of natural populations. By comparing polymorphic populations over large geographic areas and across generations, issues about both morph stability and evolutionary dynamics can be addressed, increasing our understanding of the potential mechanisms maintaining genetic polymorphisms. In the present study, we

Quality of life and toxicity in breast cancer patients using adjuvant TAC (docetaxel, doxorubicin, cyclophosphamide), in comparison with FAC (doxorubicin, cyclophosphamide, 5-fluorouracil).

Abstract in UndeterminedThe aim of this study was to compare two regimens of chemotherapy in patients with breast cancer, including FAC (doxorubicin, cyclophosphamide, and 5-fluorouracil) and TAC (docetaxel, doxorubicin and cyclophosphamide); and analyze the toxicity of these treatments and observe patient's health-related quality of life.Health-related quality of life was assessed for up to 4 mon

The glucose/xylose facilitator Gxf1 from Candida intermedia expressed in a xylose-fermenting industrial strain of Saccharomyces cerevisiae increases xylose uptake in SSCF of wheat straw

Ethanolic fermentation of lignocellulose raw materials requires industrial xylose-fermenting strains capable of complete and efficient D-xylose consumption. A central question in xylose fermentation by Saccharomyces cerevisiae engineered for xylose fermentation is to improve the xylose uptake. In the current study, the glucose/xylose facilitator Gxf1 from Candida intermedia, was expressed in three

Contact-free measurement and numerical and analytical evaluation of the strain distribution in a wood-FRP lap-joint

Wood specimens to each of which alaminate of carbon fibre reinforcement polymers(FRP) was glued (creating a lap joint in each case)were loaded to failure. A total of 15 specimens ofthree types differing in the glued length (anchoragelength) of the FRP laminate (50, 150 and 250 mmrespectively) were tested, their strength, stiffness andstrain distribution being evaluated. Synchronizeddigital cameras

Spectroscopic properties of nuclear skyrme energy density functionals.

We address the question of how to improve the agreement between theoretical nuclear single-particle energies (SPEs) and observations. Empirically, in doubly magic nuclei, the SPEs can be deduced from spectroscopic properties of odd nuclei that have one more or one less neutron or proton. Theoretically, bare SPEs, before being confronted with observations, must be corrected for the effects of the p

Calibration and validation of a modified ASM1 using long-term simulation of a full-scale pulp mill wastewater treatment plant

A mathematical model modified from the well established Activated Sludge Model no. 1 was used for modelling a full-scale wastewater treatment plant (WWTP) in a bleached kraft pulp mill. Effluents from the pulp and paper industry are typically nutrient deficient, which was considered in the model. The wastewater characterization and model calibration were based on respirometric batch experiments wi

Family History of Myocardial Infarction Increases Risk of Renal Dysfunction in Middle Age.

Background/Aims: Chronic kidney disease (CKD) is common in the general population, may lead to end-stage renal disease, and is most frequently found among males. Familial clustering of kidney diseases has been observed. We aimed to study a potential association between the family history of myocardial infarction (MI) and renal dysfunction. Methods: 22,297 males and 10,828 females, aged 33-60 years

Short- and Long-Term Hormonal and Metabolic Consequences of Reversing Gastric Bypass to Normal Anatomy in a Type 2 Diabetes Patient.

Gastric bypass (GBP) results in rapid type 2 diabetes (T2D) remission in most cases. Consequences of GBP reversal are unknown. A GBP-operated T2D patient was given mixed-meal tests before (MMTpre), 2 months (MMT2-M) and 12 months (MMT12-M) after GBP reversal. Glucose, hormones and metabolite profiles were assessed. MMT2-M displayed slightly lower glucose levels; MMT12-M displayed higher glucose an

Scenarios for investigating risks to biodiversity

Aim This paper describes a set of integrative scenarios developed in the ALARM (Assessing LArge-scale environmental Risks for biodiversity with tested Methods) project. The ultimate aim of ALARM was to develop and test methods and protocols for the assessment of large-scale environmental risks to biodiversity and to evaluate mitigation options. Scenarios provide a tool for exploring such risks and

The radical-binding lipocalin A1M binds to a Complex I subunit and protects mitochondrial structure and function.

Aims: During cell death, energy-consuming cell degradation and recycling programs are performed. Maintenance of energy-delivery during cell death is therefore crucial but the mechanisms to keep the mitochondrial functions intact during these processes are poorly understood. We have investigated the hypothesis that the heme- and radical-binding ubiquitous protein A1M (α1-microglobulin) is involved

Pregnancy rate and outcome in Swedish women with Turner syndrome

Pregnancies occurred in 57 (12%) of 482 Swedish women with Turner syndrome with a liveborn rate of 54% in 124 pregnancies. Spontaneous pregnancies occurred in 40%, mainly in women with 45,X/46,XX mosaicism, and oocyte donation in 53% where miscarriages were less frequent, odds ratio 0.43 (95% confidence interval 0.17-1.04). (Fertil Steril (R) 2011; 95: 2507-10. (c) 2011 by American Society for Rep

Quality of life in adult patients with haemophilia - a single centre experience from Sweden.

Summary: Increased or maintained health and quality of life (HRQoL) are essential goals in health care among patients with a chronic disease. To gain an understanding of HRQoL in patients with haemophilia at the Haemophilia Treatment Centre in Malmö, Sweden, patients seen from 2004-2008 were asked to complete the Short form Health Survey, SF-36, also answering to what extent haemophilia, physicall

Role of the Renner-Teller effect after core hole excitation in the dissociation dynamics of carbon dioxide dication.

The fragmentation of the doubly-charged carbon dioxide molecule is studied after photoexcitation to the C 1s(1)2π(u) and O 1s(1)2π(u) states using a multicoincidence ion-imaging technique. The bent component of the Renner-Teller split states populated in the 1s→ π∗ resonant excitation at both the carbon and oxygen 1s ionization edges opens pathways to potential surfaces in highly bent geometries i
