Aim: Topical drug delivery of fluconazole, an antifungal drug, in gel form was formulated to avoid the side effect of the oral route. Methodology: Different polymers; Sodium carboxymethyl cellulose, Sodium alginate, Carbopol 934P, Hydroxypropylmethyl cellulose, Pluronic F-127 and hydroxypropyl cellulose, were used. The compatibility of fluconazole and different gelling polymer was assessed thro...

Bone fillers have emerged as an alternative to the invasive surgery often required to repair skeletal defects. Achieving controlled release from these materials is desired for accelerating healing. Here, oppositely-charged Poly (D,L-lactic-co-glycolic acid) (PLGA) nanoparticles were used to create a cohesive colloidal gel as an injectable drug-loaded filler to promote healing in bone defects. T...

Production, viscosity, and chemical composition of xanthan synthesized by bacterium Xanthomonas campestris pv pruni strain 101 were evaluated in bioreactor systems. During the process, the volumetric oxygen mass transfer coefficient (k(L)a) and the biomass were determined and the pH was monitored. The cultures were grown in a 3 I bioreactor, with aeration and agitation varying as follows: condi...

The Brazilian biodiversity offers a multiplicity of raw materials with great potential in cosmetics industry applications. Some vegetable oils and fatty esters increase skin hydration by occlusivity, keeping the skin hydrated and with a shiny appearance. Sunflower (Helianthus annus L.) oil is widely employed in cosmetic emulsions in the form of soaps, creams, moisturizers and skin cleansers due...

Knowledge on rheological properties of sludge is important for the design of pumping and transport facilities and as a tool in process control during treatment. Concentrated activated sludge is known to behave as a non-Newtonian material. The contribution to nonNewtonian behaviour is believed to originate from the colloidal properties of solids more than from the molecular properties of the sus...

[1] Plate tectonics on Earth involves the bending deformation of plates at subduction zones, and because plates are generally considered to be stiff owning to the rheology of mantle minerals, the role of energy dissipation by plate bending in the global energy balance has been frequently debated in the recent literature. Here we consider how bending dissipation should scale with slab parameters...

The present work was aimed to prepare dried vegetarian soup supplemented with some legumes. Potatoes, hull-less barley flour, carrot, tomatoes, onion, garlic, salt, black pepper, coriander and cumin (served as F1) were used in combination with lentil, green pea and chickpea to formulate F2, F3, and F4, respectively. Chemical, physical, rheological and sensory evaluation was performed. The resul...

ABSTRACT: Mayonnaise is one of the most consumed sauces in world and beans have great technological functional properties. As a result, can be used production mayonnaise as partial substitute for egg yolk (EY), reducing cholesterol content, post-harvest losses adding nutritional value to mayonnaise. This study evaluated effect replacement EY by landrace common bean flour (LCBF) on parameters rh...

Pear pomace powder (PPP), xanthan gum (XG), and their combined effect on batter rheology, pasting properties, the quality parameters of quinoa-based gluten-free cupcakes (GFC) were investigated. The water-retention capacities flour blends, batters’ rheological blends’ properties analyzed characteristics GFCs determined. addition XG to formulation led an increase in peak viscosity, final breakdo...

Three Moroccan citrus peels, such as orange, lemon, and bigarade, were chosen to extract the pectin using Box Behnken Design. At a temperature of 90 °C, pH = 1.5, extraction time 120 min, high yield was recorded with 28.57, 26.86, 26.55% for lemon (LPP), bigarade (BPP), orange (OPP) peel pectins respectively. The extracted have less branched linear structure GalA contents BPP (86.0 mol%), LPP (...
