Because of the serious harm to animals and the environment associated with perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), a rapid, sensitive and low-cost method for detecting PFOS and PFOA is of great importance. In this paper, a novel sensing method has been proposed for th...

The synergistic combination of the food colorant Erythrosin B (E-B, FD&C 3) (0, 25, and 50 μM) and low-frequency ultrasound (20 kHz, 0.86–0.90 W mL− 1) was evaluated against Listeria innocua. Although E-B was antibacterial by itself, the inactivation rate significantly increased in a concentra...

Many flaviviruses, such as Zika virus (ZIKV), Dengue virus (DENV1-4) and yellow fever virus (YFV), are significant human pathogens. Infection with ZIKV, an emerging mosquito-borne flavivirus, is associated with increased risk of microcephaly in newborns and Guillain-Barré syndrome and other com...

Extraction of rubidium (Rb) which is an economically valuable metal from seawater reverse osmosis (SWRO) brine is beneficial. However, potassium (K) in SWRO brine hinders Rb extraction. Natural clinoptilolite zeolite in powder form was able to selectively remove K from SWRO brine (Langmuir maxim...

1.1. An unknown compound which is very similar to taurine was detected in the extract of sardine Sardinops melanosticta2.2. It was identified as d-cysteinolic acid: 2-amino-3-hydroxy-1-propanesulfonic acid from instrumental analysis.3.3. This may be the first report in which the occurrence of d-...

Astrocytes are responsible for the majority of the clearance of extracellular glutamate released during neuronal activity. dl-threo-β-benzyloxyaspartate (TBOA) is extensively used as inhibitor of glutamate transport activity, but suffers from relatively low affinity for the transporter. Here, w...

The acid catalyzed domino reaction of β-nitrostyrenes with methyl 2-(benzo[b][1,4]thiazin-3-ylidene)acetate, which were previously prepared from the cyclization of 2-aminobenzenethiol and methyl 4-chloroacetoacetate, resulted in 2-arylbenzo[b]pyrrolo[1,2-d][1,4]thiazine-3-carboxylates in high y...

The reactions of dimethylthiocarbamoyl chloride with a number of neutral and ionic iron carbonyl complexes in tetrahydrofuran are described. A variety of unusual products were obtained, viz. Fe(CO)2(S2CNMe2)2 from Fe(CO)5; Fe(CO)2(S2CNMe2)(CSNMe2) from Fe2)CO)9, Fe3(CO)12, and Fe(CO)42−; [Fe-(CO...

1.1. A lipo-amino acid, N-palmitoyl-l-serine, has been synthesized and purified by methods designed to avoid degradation reactions. The compound is structurally similar to other amino acid derivatives extracted from biological systems during the transport of amino acids2.2. NPS easily forms hydr...

Grain Size Distribution is one of the basic measurements for sediment classification. The conventional methods for grain size distribution include the sieve method, the laser diffraction method, and the point-count method. We aimed to develop a robust computer code that simulates these conventio...

BackgroundInadequate serum vitamin D levels are associated with secondary hyperparathyroidism, increased bone turnover, bone loss and increased fracture risk. Vitamin D is well recognized to be suboptimal in older patients when compared to age-matched controls. There are no published studies on ...

In observational studies, vitamin D deficiency is a risk factor for low bone density and future fractures, whereas a causal relation has been difficult to show in randomized controlled trials (RCTs). Similarly, vitamin D deficiency has been associated with increased bone turnover, but RCTs with ...

BackgroundThe aim of this study was to assess the prognostic value of vitamin D, vitamin D binding protein (VDBP) and vitamin D-related peptides in septic shock patients in relation to hospital mortality.

Let Φ be a finite dimensional algebra over an algebraically closed field k and assume gldimΦ≤d, for some fixed positive integer d. For d=1, Brüning proved that there is a bijection between the wide subcategories of the abelian category mod Φ and those of the triangulated category Db(mod Φ)...

Let T be a triangulated category. If T is a cluster tilting object and I=[addT] is the ideal of morphisms factoring through an object of add T, then the quotient category T/I is abelian. This is an important result of cluster theory, due to Keller–Reiten and König–Zhu. More general conditions ...

Let X be a variety with an action by an algebraic group G. In this paper we discuss various properties of G-equivariant D-modules on X, such as the decompositions of their global sections as representations of G (when G is reductive), and descriptions of the categories that they form. When G act...

Unilamellar dioleoylphosphatidylcholine (DOPC) liposomes (250 μM) incorporated 2 mol% of [3H]pristane at 37°C after addition of 50 μM pristane solubilized with β-cyclodextrin. Conventional solubilization in dimethyl sulphoxide resulted in much lower uptake. Premixing of perdeuterated pristan...

Infra-red spectra in the CD2 bending vibration region (1080–1100 cm−1) have been analysed for mixtures of deuterated and hydrogenated hexatriacontane. The i.r. data analyses are based on lattice dynamical calculations of guest deuterated molecules in the host n-C36H74 and infrared intensities c...

The action of the alkylating derivative of hexadecamethonium on frog neuromuscular transmission was studied with the help of intracellular microelectrodes. Treatment of frog m. cutaneous pectoris-n. pectoralis preparations with the alkylating derivative of hexadecamethonium (0.5 μM) for 30 min ...

All possible chloroprotocatechualdehydes, chlorogallaldehydes, 5-bromoprotocatechualdehyde and chloro-5-hydroxyvanillins (except 2-chloro-5-hydroxyvanillin) were synthesized. Their purity and structures were examined by liquid chromatography, mass spectrometry and other spectroscopic measurement...
