Lasiodiplodan, a (1→6)-β-d-glucan, is an exopolysaccharide with high commercial value and many applications in food, pharmaceuticals, cosmetics. Current industrial production of β-glucans from crops mostly by chemical routes generating hazardous toxic waste. Therefore, alternative sustainable eco-friendly pathways are highly desirable. Here, we have studied the lasiodiplodan sugarcane bagasse (...

Cultivations of Arthrospira platensis were carried out to evaluate the CO2 capture capacity this cyanobacterium under bench-scale conditions. For purpose, influence light intensity on microbial growth and photosynthetic efficiency has been investigated in a helical photobioreactor. Five cultivations performed at different photon flux densities (23 ≤ PPFD 225 µmol photons m−2 s−1) by fed-batch p...

Lentinan (LNT) is extracted from the fruiting body of Lentinus edodes. Its active ingredient β−1,3-dextran and has many biological activities, but its rheological characteristics antibacterial mechanism when mixed with saliva are rarely reported. In this study, LNT artificial (AS) mixture was used to investigate analysis against Streptococcus mutans (S. mutans). The results showed that apparent...

Cactus is a plant that naturally grows in tropical and semi-tropical regions of the world. The composition of this mucilage is believed to differ from species to species. Hence, comparative study was carried out on mucilages of Opuntia ficus-indica (OFI) and Opuntia stricta (OS) as regard to their physico-chemical properties and acute toxicity levels. The study indicated that solubility of the ...

Chemically stable ester derivatives of vitamins A, C and E have become a focus of interest for their role in the satisfactory results in skin aging treatments. Accordingly, the aim of this study was to evaluate the physical and chemical stability of a cosmetic formulation containing 1% retinyl palmitate, ascorbyl tetraisopalmitate and tocopheryl acetate, alone or in combination. In the studies ...

Cutaneous leishmaniasis (CL) is a resistant form of leishmaniasis that is caused by a parasite belonging to the genus Leishmania. FLU-loaded microemulsions (MEs) were developed by phase diagram for topical administration of fluconazole (FLU) as prominent alternative to combat CL. Three MEs called F1, F2, and F3 (F1-60% 50 M phosphate buffer at pH 7.4 (PB) as aqueous phase, 10% cholesterol (CHO)...

The goal of this paper was to design several sodium carboxymethylcellulose hydrogels containing a BCS class II model drug and to evaluate their flow and thixotropic properties. The rheological measurements were performed at two temperatures (23 °C and 37 °C), using a rotational viscometer. The hydrogels were stirred at different time intervals (10 s, 2, 5, 10 and 20 min at 23 °C, and 10 s, 2 an...

The aim of this study was to develop nanoemulsion containing soft extract of stem bark of Rapanea ferruginea to improve the topical delivery and anti-inflammatory activity. The extract of R. ferruginea stem bark was incorporated into the oily phase of the nanoemulsion by the method of phase inversion at low energy. The developed nanoemulsion had an average droplet size of 47.88±8.20 nm and a po...

BACKGROUND Nitrofurantoin is a nitrofuran antibiotic that has been used for treatment of urinary tract against positive and negative bacteria. OBJECTIVES The aim of this study was to evaluate the effect of structural vehicles and flocculating agents on physical stability and rheological behavior of nitrofurantoin suspension. MATERIALS AND METHODS To formulate the suspensions, the effect of ...

The present work proposes for the first time a mathematical model for describing the rheological behavior of heavy and extra-heavy crude oils in the presence of nanoparticles. This model results from the combination of two existing mathematical models. The first one applies to the rheology of pseudoplastic substances, i.e., the Herschel-Bulkley model. The second one was previously developed by ...
