Numerous plants from have been investigated due to their anti-inflammatory activity and, among then, extracts or components of ginger (Zingiber officinale Roscoe) and rosemary (Rosmarinus officinalis L.), sources polyphenolic compounds. 6-gingerol rhizome carnosic acid carnosol leaves present anti-tumor, antioxidant activities. However, the evaluation mechanisms action these other plant is limited high hydrophobicity. Dimethylsulfoxide (DMSO) commonly used as a vehicle liposoluble materials...
Liposomal encapsulation of tuberculostatic drugs can potentially increase their therapeutic index. The incorporation isoniazid, pyrazinamide, rifampicin, ethionamide, and streptomycin in extruded distearoylphosphatidylcholine/cholesterol liposomes designed for administration through inhalation was evaluated. Ethionamide rifampicin were incorporated during lipid film formation, whereas solutions the remaining used to hydrate preformed bilayers. Final drug ratios around 0.3 achieved isoniazid...
Levoglucosan is an anhydrosugar from biomass that has important applications as a platform for obtaining many value-added derivatives with high demand in the chemical industry and bioproducts by fermentation, including biofuels, among others. Thus, experimental strategy was to intensify levoglucosan production condensable fraction (bio-oil) pyrolysis gases using different pretreatments before fast according following conditions: (a) washing 10% acetic acid; (b) 0.1% HNO3, followed...
The effect of extremely low frequency (ELF) magnetic fields on ethanol production by Saccharomyces cerevisiae using sugar cane molasses was studied during batch fermentation. cellular suspension from the fermentor externally recycled through a stainless steel tube inserted in two field generators, and consequently, intensified. Two generators were coupled to bioreactor, which operated conveniently simple or combined ways. Therefore, recycle velocity intensity varied range 0.6–1.4 m s−1 5–20...
Abstract The primary goal of this study was the production liposomes encapsulating kanamycin for drug administration by inhalation. selected is indicated multiresistant tuberculosis, and through inhalation allows both local delivery to lungs systemic therapy. ethanol injection method used liposome easily scaled up characterized simplicity low cost. Vesicles were prepared using different lipid compositions, including hydrogenated soybean phosphatidylcholine cholesterol (SPC/Chol), egg...
Abstract Over the past few decades liposomes, which are lipid vesicles useful for controlled release of numerous bioactive compounds, have attracted significant industrial interest. Several techniques evolved manufacture liposomes on a small scale. However, production commercially feasible scale is still somewhat limited. Therefore, this research intends to evaluate scale‐up potential liposome unit using ethanol injection method, through preliminary economical feasibility estimation, as an...
The aim of this work was to evaluate the performance different extruded catalysts containing K 2 CO 3 as active phase and adding conveniently γ ‐Al O and/or sepiolite magnetic particles on biodiesel production from sunflower oil by ethanolic route. Firstly, content Fe 4 catalyst (0.1, 0.2, 0.3, 0.4 g /g / ), after calcination step, evaluated verify separation facility with properties reactional medium, using an external field, at end synthesis. After that, three were considered for...
FLUID EXTRACTION.The aim of this work was to evaluate the antioxidant properties ginger and rosemary extracts, obtained by supercritical extraction.The extracts were characterized HPLC, GC-MS, phenolic compounds content activity.The main active identified high observed.The presented activity against free radicals ABTS •+ (350 200 mM Trolox/g, for rosemary, respectively) DPPH • (145 80 respectively).These results suggested that attained are potential substitutes synthetic antioxidants used in...
