In a constantly changing economic environment strong developed countries created significant management models to follow. 5S, as part of Toyota Production System (the most used management model in automotive industry), is a method which develops discipline and cleanliness at workplace, maximizin...

The karyotype of Piptanthus concolor was analysed via fluorescence in situ hybridization (FISH) using oligonucleotide probe for ribosomal DNA (rDNA) (5S rDNA, 41 bp). P. concolor had 2n = 18 chromosomes. The karyotype was composed of 3 pairs of metacentric chromosomes (including one pair of sate...

Abalone is an extremely valuable food source derived from cultured and wild animals, the later from populations under intense fishing exploitation and of high conservation value. As part of a long-term study to characterize genes from abalone that can be used as markers for hybrids certification...

IntroductionAs the current methods to predict the inhalation toxicity of chemicals using animal models are limited, alternative methods are required. We present a new in vitro prediction method for acute inhalation toxicity using the Calu-3 epithelial cytotoxicity assay applicable for water-solu...

Poly [(±)-2-(sec-butyl) aniline]/silica-supported perchloric acid composites were synthesized by combination of poly[(±)-2-sec-butylaniline] base (PSBA) and the silica-supported perchloric acid (SSPA) as dopant solid acid in solid-state. The X-ray photoelectron spectroscopy (XPS) and CHNS resu...

From 2002 to 2003, a global pandemic of severe acute respiratory syndrome (SARS) spread to 5 continents and caused 8000 respiratory infections and 800 deaths. To ameliorate the effects of future outbreaks as well as to prepare for biodefense, a process for the production of a recombinant protein...

Clostridium saccharoperbutylacetonicum N1-4 (HMT) is known as a hyper acetone-butanol-ethanol (ABE) producing strain. Within its genome, there is an endogenous megaplasmid (Csp_135p) of 136 kb, which contains 104 protein-encoding genes and two pseudogenes. Till now, the function of the megaplasm...

A facile and efficient one-pot synthesis of 3-(furan-2-yl)-4-hydroxy-2H-chromen-2-ones was developed. The reaction of ethyl 3-(2-hydroxyphenyl)-3-oxopropanoates and 2,5-dimethoxy-2,5-dihydrofuran were performed in presence of K10 Montmorillonite Clay heterogeneous catalyst under the solvent-free...

2-(Furan-2-yl)- and 2-(thiophen-2-yl)pyrroles are readily ethynylated with acylbromoacetylenes in the solid Al2O3 medium (no solvent, room temperature, 1 h) to afford 5-(furan-2-yl)- and 5-(thiophen-2-yl)-2-acylethynylpyrroles in 39–74% yields. In the case of 2-(furan-2-yl)pyrroles, an alternat...

A 4-(furan-2-yl)phenyl-containing conjugated dithienylpyrrole (FPT) was prepared using a Paal-Knorr reaction and its homologous homopolymer (PFPT) and copolymers (P(FPT-co-DTC) and P(FPT-co-DTP)) were electrosynthesized. Spectroelectrochemical investigations displayed that PFPT film was saffron ...

(η5-C5H5)(CO)2FeCH(CH3)SPh (8) serves as a quite useful reagent for the transfer of ethylidene groups to alkenes to give methyl-substituted cyclopropanes in good yields. The reaction is accomplished by allowing 8 to react with an alkylating agent such as trimethyloxonium tetrafluoroborate or me...

Difluoro{(1S∗,2S∗)-2-[(1S∗)-1-(6-oxo-1,6-dihydro-9H-purin-9-yl)ethyl]cyclopropyl}methylphosphonic acid 12a and the related analogues were prepared as ‘multi-substrate analogue’ inhibitors for purine nucleoside phosphorylase. Reduction of diethyl [(1S∗,2S∗)-2-acethylcyclopropyl](difluoro)methyl...

Addition reaction of two geometrical isomers of 1-chlorovinyl p-tolyl sulfoxides, derived from unsymmetrical ketones and chloromethyl p-tolyl sulfoxide, with lithium enolate of tert-butyl acetate gave single diastereomers of the adduct, respectively. Treatment of each diastereomer with i-PrMgCl ...

A number of new imine derivatives of 5-amino-1, 3, 4-thiadiazole-2-thiol have been synthesized, and their anti-depressant activity was tested using imipramine as reference drug. Two compounds namely 5-{[1-(4-chlorophenyl)-3-(4-methoxy-phenyl)prop-2-en-1-ylidene]-amino}-5-benzylthio-1, 3,4 -thiad...

Drug-resistant bacteria associated with biofilm formation are rapidly on the rise, requiring novel therapeutic options to combat biofilm induced drug-resistance. In this study, a class of 3-hydroxy-2-(phenylhydroxy-methyl)-6-methyl-4H-pyran-4-one derivatives (1a-1e) were found by screening of an...

Novel 1-(2-aryl-2-adamantyl)piperazine derivatives have been synthesized and evaluated in vitro for their antitumor properties against HeLa cervical carcinoma, MDA MB 231 breast cancer, MIA PaCa2 pancreatic cancer, and NCI H1975 non-small cell lung cancer. The parent piperazine 6 was found to ex...

A new series of N6-[(hetero)aryl/(cyclo)alkyl-carbamoyl-methoxy-phenyl]-(2-chloro)-5′-N-ethylcarboxamido-adenosines (24–43) has been synthesised and tested in binding assays at hA1, hA2A and hA3 adenosine receptors, and in a functional assay at the hA2B subtype. The examined compounds displaye...

Marine biomass and terrestrial biomass have distinct compositions and structures. In order to understand the effect of feedstock difference on deoxy-liquefaction products, the experiments were performed with marine biomass (Enteromorpha prolifera, Giant kelp, Undaria pinnatifida) and terrestrial...

A systematic structural separation study was carried out for the separation of Pr(III) and Fe(III) from nitric acid medium with unsymmetrical diglycolamides (DGAs). Four kinds of diglycolamides, N,N′-di-methyl-N,N′-di-dodecyl diglycolamide (DMDDdDGA), N,N′-di-ethyl-N,N′-di-dodecyl diglycolam...
