The importance of ascorbic acid (AA) in the human diet has motivated food researchers to develop AA-fortified food products. However, this compound is very unstable. The aim of this work was to produce solid lipid microcapsules (SLMs) loaded with AA using microfluidic technology. The morphology of the SLMs was analysed by optical, scanning electron and confocal microscopy. We determined the enc...

Purpose Paediatric solid cancers such as osteosarcoma, Ewing ́s sarcoma, rhabdomyosarcoma and neuroblastoma are the most common cancers in children besides leukemia. These cancers have a poor prognosis, are highly metastatic and often resistant to current therapeutic approaches. Viscum album L. (mistletoe) is one of the most widely used complementary cancer therapies in Germany but little is kno...

The photovoltaic industry generates large amounts of waste graphite (WG) that contains useful metals can be recycled into high-value products. This study elucidated the impurity elements and their existence states in WG, analyzed verified source main phase SiC, determined SiC content to 4.66%. WG was purified using an alkaline-acid method, whose optimal process parameters were a solid alkali ra...

The genes for cytidine monophospho-N-acetylneuraminic acid hydrox ylase (NeuAc-H) and fl.1,4.N-acetylgalactosaminyl transferase (GalNAc T)were examined using reverse transcription-PCR in two experimental mouse brain tumors, EPEN and CT-2A. NeuAc-H is required for the synthesis of gangliosides containing N-glycolylneuraminic acid, whereas GalNAc-T is required for the synthesis of ganglioside GM2...

[b(oh)3]0.78[b(oh)2(oso3h)]0.22 or (bsa) was simply prepared by addition of chlorosulfonic acid to commercial boric acid at room temperature. this cheap and green solid acid was used as an efficient catalyst for synthesis of acylals from aldehydes under solvent-free conditions at room temperature.

Fructose is a versatile precursor for food and chemicals. Currently, catalytic production of fructose achieved by enzymatic isomerization glucose from renewable lignocellulose. Although the catalyst, isomerase, selective, it not stable. Here, aluminum-containing metal-organic frameworks (Al-MOFs) are shown to be active, stable, reusable in ethanol. Al-MOFs 64% selectivity with 82% conversion at...

A salt with the composition [C12H9N2][C8H3Cl2O4] (1) with 4,5-dichlorophthalic acid and 1,10phenanthroline (phen) has been synthesized and characterized by IR, UV spectroscopy, elemental analysis, and X-ray crystallography. Compound 1 represents a 3D chiral supramolecular framework containing monohelical chains (21 axis) through multiform C–H· · ·O, O–H· · ·O, N–H· · ·N intramolecular hydrogen ...

Novel solid supports, consisting of polypropylene blended with various agricultural materials (pp composite), were evaluated as supports for pure- and mixed-culture continuous lactic acid fermentations in biofilm reactors. Streptomyces viridosporus T7A (ATCC 39115) was used to form a biofilm, and Lactobacillus casei subsp. rhamnosus (ATCC 11443) was used for lactic acid production. For mixed-cu...

This paper presents an alternative strategy for manufacturing solid-state reference electrodes based on particles of graphite/silver/silver chloride synthesized by electroless deposition of metallic silver and silver chloride on graphite powder. Two kinds of reference electrodes were manufactured by mixing these particles with epoxy resin and hardener: quasi-reference and all-solid-state contai...

The purpose of this investigation was to prepare a gastro retentive drug delivery system of famotidine tablets. Floating tablets of famotidine were prepared employing lipid solid dispersion spray drying technique with gelucire 50/13 and compritol 888 along with HPMC K100M, lactose, sodium bicarbonate and citric acid. The floating tablets were evaluated for uniformity of weight, hardness, friabi...
