1. On the Use of a TiO2 Sol-Gel for Horseradish Peroxidase Enzyme Immobilization for Development of an Amperometric Biosensor
The sol-gel technique has drawn considerable attention in the area of biomolecules immobilization by virtue of its intrinsic properties including chemical inertness, thermal stability, and good biocompatibility. The present work reports the development of a bio-sensing methodology which involves the immobilization of horseradish peroxidase enzyme (HRP) on pe

2. Alcoholmeter as a Simple and Accessible Way for Ethanol Determination in Alcohol-Based Hand Sanitizers
Expensive and complex methodologies are available to determine the ethanol concentration in alcohol gel samples. The aim of this article was to demonstrate that alcoholmeter could be used as an alternative method to determine ethanol in gel formulations. Alcohol gel samples were produced using: hydroxypropylmethylcellulose (HPMC), hydroxyethylcellulose (HEC)

5. The efficacy of sustained-release chitosan microspheres containing recombinant human parathyroid hormone on MRONJ
Abstract Treatment of patients with bisphosphonate usage is a significant concern for oral surgeons because it interferes with jaw bone turnover and regeneration. In case of adverse effects manifesting related to bisphosphonate use, oral surgeons are usually treating and keep the patient’s symptoms under control. In this study, we aimed to investigate a ne

6. Geopropolis gel for the adjuvant treatment of candidiasis – formulation and in vitro release assay
ABSTRACT The geopropolis produced by the stingless bee Melipona subnitida (popularly called "jandaíra" in Brazil) is a mixture of resin, wax, and mud. This study analyzed the antifungal activity of the geopropolis extract from Candida spp., developed a gel formulation with this extract and analyzed the delivery of bioactives (kinetics release) in the formul

11. Liposomes as potential carriers for ketorolac ophthalmic delivery: formulation and stability issues
ABSTRACT Drug delivery to treat ocular disorders locally is a challenging endeavor. Traditional ocular dosage form - eye drops - exhibits poor availability, consequently inefficient therapeutic response. The objective of the study was to formulate and characterize a ketorolac tromethamine ocular system with a prolonged release pattern based on liposomes as a

12. Development and validation of an analytical method using High Performance Liquid Chromatography (HPLC) to determine ethyl butylacetylaminopropionate in topical repellent formulations
ABSTRACT Diseases caused by insects are frequent in poor countries, leading to epidemic scenarios in urban areas; e.g., Dengue, Zika and Chikungunya. For this reason, the development of a safe and efficient topical formulation is essential. Ethyl butylacetylaminopropionate (EB) is a mosquito repellent developed by Merck, which is used in products for adults,
