Pretreatments are one of the main bottlenecks for lignocellulose conversion process and search cheaper effective pretreatment methodologies each biomass is a complex but fundamental task. Here, we used 2ν5−1 fractional factorial design (FFD) to optimize five variables: milling time, temperature, double treatment, chemical concentration, time in acid–alkali (EA) acid–organosolv (EO) pretreatments, applied elephant grass leaves. FFD allowed optimization conditions using reduced number...

Abstract Inflammatory conditions of the temporomandibular joint (TMJ) and peripheral tissues affect many people around world are commonly treated with non-steroidal anti-inflammatory drugs (NSAIDs). However, in order to get desirable results, treatments NSAIDs may take weeks, causing undesirable side effects requiring repeated administration. In this sense, work describes development an optimized nanostructured lipid carrier (NLC) formulation for intra-articular administration naproxen...

A method for sulfur determination in diesel fuel employing near infrared spectroscopy, variable selection and multivariate calibration is described. The performances of principal component regression (PCR) partial least square (PLS) chemometric methods were compared with those shown by multiple linear (MLR), performed after based on the genetic algorithm (GA) or successive projection (SPA). Ninety seven samples divided into three sets (41 calibration, 30 internal validation 26 external...

The dehydration reaction of d-(−)-fructose into 5-(hydroxymethyl)furfural (HMF) in both batch and continuous flow conditions was comprehensively studied using the statistical tool design experiments (DoE), employing i-PrOH/DMSO as solvent system presence solid acid catalyst Amberlyst-15. Initially, screening different alcohols (MeOH, EtOH, i-PrOH, t-BuOH) showed that i-PrOH provides better selectivity yield compared to other alcohols, along with minimum formation byproducts when associated...

Topical anesthetics are widely applied in order to relieve the discomfort and anxiety caused by needle insertion other painful superficial interventions at oral cavity. So far, there no commercially available effective topical anesthetic formulations for that purpose, most of developments related hydrophilic low mucoadhesive forms. Therefore, we have prepared different hybrid nanofilms composed biopolymer matrices (chitosan, pectin, chitosan-pectin) blended with nanostructured lipid carriers...

Abstract Tetracaine (TTC) is a local anesthetic broadly used for topical and spinal blockade, despite its systemic toxicity. Encapsulation in nanostructured lipid carriers (NLC) may prolong TTC delivery at the site of injection, reducing such This work reports development NLC loading 4% TTC.

Campylobacter jejuni (CJ) is the most prevalent zoonotic pathogen of chicken meat and related products, which may lead to gastroenteritis autoimmune diseases in humans. Although controlling this bacterium important, CJ strains resistance against traditional antibiotic therapy has been increased.
