Rossi, Marco published the artcileSeparation of O- and C-allyl glycoside anomeric mixtures by capillary electrophoresis and high-performance liquid chromatography, Related Products of alcohols-buliding-blocks, the main research area is allyl glycoside anomer capillary electrophoresis liquid chromatog.

Rapid and reliable methods for the anal. of O- and C-allyl galactopyranosides and glucopyranosides are presented, based on capillary zone electrophoresis (CZE) and micellar electrokinetic capillary chromatog. (MEKC). In MEKC, the formation of chromophoric and charged complexes between the saccharides and borate as well as the hydrophobic interactions with micelles jointly contributed to the selective separation and sensitive detection of all the investigated anomeric couples. Some non-purified synthesis mixtures of C-allyl glycosides were successfully characterized without pre-treatment. MEKC buffer conditions for which glycosides separation was successfully achieved were then exported and applied to reverse-phase liquid chromatog. (RP-HPLC), for the quant. isolation of each allyl glycoside anomer. Identification of the obtained anomeric products was performed by electrospray mass spectrometry and 13C NMR spectroscopy. Glycoside-solvent interactions driving the selective anomeric separation were shortly addressed and discussed on the basis of sugar derivatives structural differences.

Park, Sang-Seo published the artcileExercise attenuates maternal separation-induced mood disorder-like behaviors by enhancing mitochondrial functions and neuroplasticity in the dorsal raphe, Formula: C4H6O5, the main research area is biomarker exercise animal behavior maternal separation neuroplasticity mood disorder; caspase Bax dorsal raphe mitochondrial dysfunction mood disorder; Apoptosis; Dorsal raphe; Exercise; Maternal separation; Mitochondria; Mood disorder.

Loss of the mother-infant relationship during early childhood affects infant development and is known to increase the infant’s vulnerability to neuropsychiatric disorders throughout life. Serotonin deficits and mitochondrial dysfunction in the dorsal raphe may underlie mood disorders such as anxiety and depression. Exercise is known to have a pos. effect on brain function. In this study, we investigated the effect of exercise on mitochondrial function, apoptosis, and serotonin levels in the dorsal raphe as well as behavioral changes in cases of maternal separation Exposure to the stress of maternal separation resulted in mitochondrial dysfunction in the dorsal raphe, including impaired Ca2+ homeostasis, an increase in reactive oxygen species such as H2O2, and a decrease in the O2 respiration rate. Exposure to maternal separation stress also decreased tryptophan hydroxylase and 5-hydroxytryptamine pos. cells and increased apoptosis, anxiety, and depression. The impairments in mitochondrial function, apoptosis, and serotonin in the dorsal raphe, as well as anxiety and depression, were all improved by exercise. Exercise might alter mitochondrial function, serotonin levels, and the rate of apoptosis in the dorsal raphe. Therefore, exercise might be an important non-pharmacol. intervention for the prevention and treatment of the adverse effects of maternal separation

Vorobyova, Viktoria published the artcileInhibition of mild steel corrosion in sodium chloride solution by apricot waste extract obtained from different solvent systems, Related Products of alcohols-buliding-blocks, the main research area is mild steel apricot waste corrosion morphol.

Purpose: This paper aims to investigate influence of extraction solvent on the efficacy of apricot pomace extract (APE) as a sustainable corrosion inhibitor for mild steel in sodium chloride solution Design/methodol./approach: The chem. profiles of the extracts were analyzed using gas chromatog.-mass spectrometry. Total phenolic, total flavonoid content and antioxidant properties of the extracts were determined Besides, gravimetric, potentiodynamic polarization and at. force microscopy were used to study the corrosion inhibition. The effect of immersion period on inhibition efficiency was evaluated. The reaction mechanism of the inhibitor was also discussed. Findings: Corrosion inhibition decreasing is in the following order: solution of 2-propanol/ethanol apricot pomace (E/PAPE) extract > ethanol (EAPE) > 2-propanol (PAPE). The gravimetric, polarization measurements and surface anal. revealed that the growth of inhibitory properties is prolonged, and corrosion rate reduction after 40-48 h of exposure was studied. Practical implications: APEs play an important role in the corrosion inhibition of mild steel in sodium chloride solution Moreover, its application is potentially possible in industries. Social implications: The results contribute to the integrated valorization of food waste. Originality/value: The different compositions of the conversion/oxidation products of organic substances in solution were studied. The formation of polymerized flavanol-aldehyde adducts and oxidized quinone compounds or tautomers structures because of extract transformation in water causes main corrosion reduction in 40-48 h.

Koendjbiharie, Jeroen G. published the artcileThe PEP-pyruvate-oxaloacetate node: variation at the heart of metabolism, HPLC of Formula: 97-67-6, the main research area is review glycolysis TCA phosphoenolpyruvate pyruvate oxaloacetate; PPO-node; central metabolism; enzyme biochemistry; oxaloacetate; phosphoenolpyruvate; pyruvate.

At the junction between the glycolysis and the tricarboxylic acid cycle-as well as various other metabolic pathways-lies the phosphoenolpyruvate (PEP)-pyruvate-oxaloacetate node (PPO-node). These three metabolites form the core of a network involving at least eleven different types of enzymes, each with numerous subtypes. Obviously, no single organism maintains each of these eleven enzymes; instead, different organisms possess different subsets in their PPO-node, which results in a remarkable degree of variation, despite connecting such deeply conserved metabolic pathways as the glycolysis and the tricarboxylic acid cycle. The PPO-node enzymes play a crucial role in cellular energetics, with most of them involved in (de)phosphorylation of nucleotide phosphates, while those responsible for malate conversion are important redox enzymes. Variations in PPO-node therefore reflect the different energetic niches that organisms can occupy. In this review, we give an overview of the biochem. of these eleven PPO-node enzymes. We attempt to highlight the variation that exists, both in PPO-node compositions, as well as in the roles that the enzymes can have within those different settings, through various recent discoveries in both bacteria and archaea that reveal deviations from canonical functions.

Brain is the main organ that manages all other organs and has significant oxygen requirements, which makes it vulnerable to reactive oxygen species, thus causing different neurol. disorders. The aim of this work is the evaluation of Lavandula officinalis essential oil neuroprotective effect against hydrogen peroxide (HP)-induced toxicity in mice. Essential oil was extracted by hydrodistillation using a Clevenger-type apparatus Essential oil anal. is performed using gas chromatog.-mass spectrometry (GC-MS). Biol. activity evaluation carried out the ferric reducing antioxidant power test, DNA (DNA) fragmentation assay, the histopathol. study of the brain, and determination of antioxidant enzyme activities. Chem. characterization of essential oil using GC-MS identified 47 compounds, accounting for almost 80% of the total oil and indicates the occurrence of monoterpenes and sesquiterpenes. The identified major compounds are pentanone (16.55%), propanal (15.89%), Me Et ketone (13.51%), naphthalene (10.81%), terpinen-4-ol (6.55%), cyclopentanecarboxylic acid (4.77%), and isoborneol (2.27%). This study allowed us to investigate the effects of HP on brain function in Mus musculus adult mice by assessing DNA degradation, cell morphol., oxidative balance and brain weight variation. Furthermore, we have highlighted the beneficial effects of L. officinalis essential oil, which could significantly counteract all these alterations by its active compounds, which are endowed with potent biol. activities. We can conclude that HP-induced damage in histomorphol. changes in mice brain, significant atrophy, as well as an important alteration of the genetic expression.

Mahendran, Thevaki published the artcileAroma volatiles components of ‘Fuerte’ Avocado (Persea americana Mill.) stored under different modified atmospheric conditions, Category: alcohols-buliding-blocks, the main research area is aroma avocado volatile compound ripening.

Modified atm. (MA) storage have direct influence on biogenesis and releasing of aroma volatiles in the ripe fruits. A study was conducted to investigate the influence of MA storage on the volatile constituents of ripe avocados. Mature avocados (cv. Fuerte) were packed in four different packaging materials and the equilibrium gas composition developed within the packs were in perforated polyvinylchloride: SM-60 (Control: 20.8% O2 + 0.03% CO2), Micro-porous polypropylene: MY-15 (4.8% O2 + 8.4% CO2), Low d. polyethylene: LPDE (7.7% O2 + 5.8% CO2) and Micro-porous polypropylene: MD-15 (9% O2 + 5.4% CO2). The MA packs of avocados were stored at 7°C for 4 wk and were ripen at 20°C. The volatile compounds of ripe avocados were investigated by means of gas chromatog. (GC) and GC-mass spectrometry. A total of 68 of components were identified among those Bu acetate, 3-hexenyl acetate, 2-hexenyl acetate and hexyl acetate were only detected from MA stored avocados. Therefore, the MA storage with suitable gas composition could be used as a novel technol. to extend the shelf life without significantly (p > 0.05) affecting the volatile components of the avocados.

Kallai, Nikolett published the artcileEvaluation of drug release from coated pellets based on isomalt, sugar, and microcrystalline cellulose inert cores, Application of (3R,4R,5R)-6-(((2S,3R,4S,5S,6R)-3,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexane-1,2,3,4,5-pentaol, the main research area is diclofenac sodium pellet dissolution isomalt Eudragit microcrystalline cellulose.

The objective of the present study was to investigate the effect of the pellet core materials isomalt, sugar, and microcrystalline cellulose on the in vitro drug release kinetics of coated sustained-release pellets as well as to evaluate the influence of different ratios of polymethacrylate copolymers exhibiting different permeability characteristics on the drug release rate. For characterization of the drug release process of pellets, the effect of osmolality was studied using glucose as an osmotically active agent in the dissolution medium. The pellet cores were layered with diclofenac sodium as model drug and coated with different ratios of Eudragit RS30D and Eudragit RL30D (ERS and ERL; 0:1 and 0.5:0.5 and 1:0 ratio) in a fluid bed apparatus Phys. characteristics such as mech. strength, shape, and size proved that the inert cores were adequate for further processing. The in vitro dissolution tests were performed using a USP Apparatus I (basket method). The results demonstrated that, besides the ratio of the coating polymers (ERS/ERL), the release mechanism was also influenced by the type of starter core used. Sugar- and isomalt-type pellet cores demonstrated similar drug release profiles.

Saska, Zs. published the artcileEffect of isomalt as novel binding agent on compressibility of poorly compactable paracetamol evaluated by factorial design, Application In Synthesis of 64519-82-0, the main research area is isomalt compressibility compactability paracetamol tablet.

Tablets containing paracetamol were prepared by wet granulation. The model drug, paracetamol (API) and the diluent, milled isomalt (IM) were applied in different ratios where the granulation liquid was kept constant in each sample. The purpose of the study was to investigate the effect of wet granulation with milled isomalt on the tabletting properties of poorly compressible paracetamol. The results of tabletting process and the tablet characteristics were evaluated with 32 type face-centered full factorial design. The API:IM ratio (X 1) and compression force (X 2) were selected as independent variables. The dependent variables were as follows: the parameters of the tabletting process – lubrication coefficient (R-value), relative elasticity, friction work – and characteristics of the dosage form such as tablet hardness, friability, disintegration time, tensile strength. The results indicated that milled isomalt has an advantageous effect on both the process of compression and the tablet characteristics – due to its binder properties. Furthermore an optimal composition of the API and the diluent is dependent on the compression process and the dosage form.
