In this study, polyphenols were extracted from pomegranate peels with solid-liquid (SL), ultrasound (US) and Ired-Irrad®, a newly-patented infrared (IR) extraction technique. Deep eutectic solvents were used as green alternatives to conventional aqueous or organic solvents. The extraction proces...

Polymerizations of methyl methacrylate and ethyl methacrylate with combinations of t-butyllithium and several bulky alkylaluminum bisphenoxides were carried out in toluene at −78°C. Methylaluminum bisphenoxide derivatives gave heterotactic polymers which comprise an alternating sequence of meso...

This report describes the synthesis of a series of magnesium complexes bearing sterically congested phenoxide ligands and their catalytic performances in initiating immortal Ring Opening Polymerization of ε-caprolactone and rac-lactide. The magnesium complexes Mg1-Mg3 were obtained in high yiel...

We report an optimized synthesis of aluminum n-hexyloxide (AH), aluminum phenoxide (APh) and aluminum isopropoxide (AIP) with high yields. Aluminum alkoxides, among other applications, are important starting materials to produce high surface area alumina catalyst supports for catalytic applicati...

A synthetic route to obtain crystalline aluminum phenoxide was established. Its molecular structure in solid-state and solution is unambiguously determined by single-crystal X-ray diffraction and 1H, 13C and 27Al NMR spectroscopy. The single-crystal X-ray analysis revealed the presence of the di...

The modification of MWCNTs with Prussian Blue (PB) represents a significant improvement of the energy density values of asymmetric carbon based supercapacitors (CBSCs) in neutral media (KCl). The development of the faradaic processes associated with the presence of PB on the positive electrode i...

Three covalent anthocyanin–flavonol complexes (pigments 1–3) were extracted from the violet-blue flower of Allium ‘Blue Perfume’ with 5% acetic acid-MeOH solution, in which pigment 1 was the dominant pigment. These three pigments are based on delphinidin 3-glucoside as their deacylanthocyani...

The lack of a strategic planning to order a defined marine territory may result in a patchwork of overlapping policies, sometimes reinforcing the legislation, but sometimes contradicting it. In Brazil, Integrated Coastal Zone Management (ICZM) and Marine Protected Areas (MPAs) policies have been...

Removal of dye from the industrial wastewater is one of the most important subjects in water pollution regulation. Successive adsorption/desorption cycles of a basic dye, methylene blue, on the internal almond shell, sheep manure waste and sawdust were investigated using fixed bed column experim...

The aim of the study was to evaluate the effect of the different methods of preparation of the blue honeysuckle (Lonicera caerulea L. var. Kamtschatica) cv. ‘Wojtek’ and their influence on the iridoid content of fruit juices and fresh and freeze-dried pomaces. Compounds were identified by UPLC...

Doxapram HCl (3,3-diphenyl-1-ethyl-4-[β-morpholinoethyl]-2-pyrrolidinone hydrochloride monohydrate: Dopram®: AHR-619), a new respiratory stimulant, was studied in several species to characterize its toxicity and assess its safety.The intravenous LD50 in mice, rats, dogs, and cats was approximat...

The effectiveness of naloxone and doxapram in reversing the respiratory depressant actions of fentanyl and droperidol in the rabbit has been examined. Both drugs did not reverse fully the depression of respiratory frequency produced by the neuroleptanalgesic agents. Doxapram also failed to rever...

Doxapram hydrochloride was administered to unrestrained, conscious animals by continuous intravenous infusion. Respiratory stimulant and convulsant doses were recorded and a ratio of these doses was determined for each species under test. Ratios were found to be 38:1 for the cat, 10:1 for the ra...

A number of drugs have been used to treat asphyxia in new-born calves and the aim of the current study was to investigate the effect of commonly-used stimulant drugs on ventilation, arterial blood gas and acid base variables. A group (n = 18) of new-born (3–15 h old) calves were treated in a ra...

In an effort to develop novel inhibitors of receptor for advanced glycation end products (RAGE) for the treatment of Alzheimer's disease, a series of pyrazole-5-carboxamides were designed, synthesized and biologically evaluated. Analyses of the extensive structure–activity relationship (SA...

The pharmacologic activity of the hexapeptide fragment corresponding to the amino acid fragment 60–65 in β-lipotropin, (β-LPH-(60–65)) was studied in vitro and in vivo. In binding assays on synaptosomal plasma membrane the peptide was found to be equipotent to met-enkephalin, but behaved dif...

We present trace element data for HFSE-rich minerals (titanite, eudialyte, Ti-bearing andradite, zircon) from plutonic rocks of the Eocene Tamazeght complex, High Atlas Mountains, Morocco. In most lithologies significant amounts of titanite are present and as such, titanite fractionation played ...

Bayer red mud (RM) is an alumina refinery waste product rich in aluminum oxides and alkalis which are present primarily in the form of sodium hydro-aluminosilicate desilication product (DSP). A hydrothermal process was employed to recover alumina and alkali from “Fe-rich” and “Fe-lean” RM, t...

Clinopyroxenes from pyroxenite, ijolite and nepheline syenite from the main intrusion of the Alnö complex define two sub-parallel compositional trends with respect to Na, Ca and FeTOT plotted against alkali-pyroxene fractionation index (Na–Mg). Both trends define a smooth fractionation of incre...

Titanium-bearing (hydro)andradites from hydrothermally altered mantle section of the Nagaland ophiolite, India have been investigated for mineral chemical study. In serpentinized peridotite they occur in association with accessory chromites or dusty magnetites and the TiO2 content in them is rel...
