Marine red macroalgae have received much attention as sustainable resources for producing bio-based products. Therefore, understanding the metabolic pathways of carbohydrates from red macroalgae, in fermentative microorganisms, is crucial for efficient bioconversion of the carbohydrates into bio...

Easy procedure was devised to obtain di-O-isopropylidene-l-galactose from di-O-isopropylidene-d-galactose.

l-Galactose (l-Gal) containing N-glycans and cell wall polysaccharides have been detected in the l-Fuc deficient mur1 mutant of Arabidopsis thaliana. The l-Gal residue is thought to be transferred from GDP-l-Gal, which is a structurally related analog of GDP-l-Fuc, but in vitro l-galactosylation...

l-Arabinose and d-galactose are the principal constituents of l-arabinogalactan, and also co-occur in other hemicelluloses and pectins. In this work we hypothesized that similar to the induction of relevant glycoside hydrolases by monomers liberated from these plant heteropolymers, their respect...

Impaired skin wound healing in the elderly can lead to medical issues and increased mortality. Although l-histidine and l-carnosine are potent anti-aging amino acids, the wound healing effects of these amino acids in aging remain to be elucidated. Here, we investigated the regenerative potential...

Publisher SummaryThis chapter discusses the analytical profile of methoxamine hydrochloride. Methoxamine is a synthetic aminobenzyl alcohol derivative, active as a directly acting sympathomimetic amine with a prompt and prolonged pressor action which results almost exclusively from a-adrenergic ...

Some pharmacologically active amines such as amphetamine, the isomeric o-, m- and p-methoxyamphetamines, 4-phenylbutan-2-amine and mexiletine, as well as their corresponding acetamides, have been prepared in high yields and with very high enantiomeric excesses. The method consists of the Candida...

The unit cell dimensions of sotalol hydrochloride have been determined by powder diffraction using X-ray data collected on a laboratory source. A Bayesian method for estimating the number of reflections contributing to any given peak has been used to provide the best estimates of the reflection ...

Single crystal of a new [(CH3)2CHNH3]4Cd3Cl10 compound was grown and its properties have been characterized by dielectric and dilatometric investigations. Dielectric measurement evidenced the phase transitions at T1 = 352.8 K, T2 = 293.5 K and T3 = 261.5 K on cooling run. Dilatometric measuremen...

An amphetamine analog, P-1727, dl-(p-trifluoromethylphenyl) isopropylamine hydrochloride, has been shown to cause blood-vascular changes in the posterior compartment of the dog's eye on prolonged oral treatment. It is believed the resultant anoxia in the retinochoroid area produced degenera...

Thallium (Tl) is a typical toxic metal, which poses a great threat to human health through drinking water and the food chain (biomagnification). China has rich Tl-bearing mineral resources, which have been extensively explored and utilized, leading to release of large amounts of Tl into the envi...

The phase diagram for the quasi-binary Tl2Te–Bi2Se3 system was delineated from the results of phase studies by both common thermal analysis and X-ray diffraction. Numerical values of the phase transition temperatures at different alloy compositions within the whole concentration range, were obt...

There is tremendous need for the 2D graphene-like single and multiple layered materials since they can be very useful as multifunctional materials for electronic, optical and energy generation and storage applications. We describe the preparation and morphology of selenide crystals and compared ...

Composite materials based on III–VI elements are promising in designing efficient photoelectronic devices, such as thin film organic–inorganic solar cells. In this work, TlSe composite materials were synthesized on a model polymer polyamide using temperature and pH controlled adsorption–diffu...

Crystal structure of a novel quaternary thallium indium germanium selenide TlInGe2Se6 was investigated by means of powder X-ray diffraction method.

The phase diagram for the quasi-binary Tl2Se–SnSe2 system was constructed based on the results of studies by both thermal analysis and X-ray diffraction. The diagram was compared with two other diagrams for the same system published earlier by other authors. The study produced substantial evide...

The Tl2Se–In2Se3 cross section of the Tl–In-Se system was studied by both the common thermal analysis (TA) and the X-ray diffraction (XRD). From the results of the studies the phase diagram for the quasi-binary Tl2Se–In2Se3 system was delineated for the first time. Numerical values of the pha...
