Aims: The objective of this work was to study the influence of the sugar source on exopolysaccharide (EPS) production and the activities of the enzymes involved in the synthesis of sugar nucleotides in Lactobacillus case...

The fabrication of photonic and electronic structures and devices has directed the manufacturing industry for the last 50 years. Currently, the majority of small-scale photonic devices are created by traditional microfab...

Objective: This study was aimed at the formation and evaluation of the mucoadhesive gastro-retentive tablet of domperidone to overcome the drawbacks related to the oral administration of drugs. These gastro retentive for...

This study evaluates the low-velocity impact response of aerospace-grade epoxy laminates (M18/1) interleaved with four distinct thermoplastic films (PEI, PES, PSU, PC). Impact performance was correlated with quasi-static...

Abstract The miscibility behaviour of polybenzylmethacrylate (PBMA) blends with polyethylene oxide (PEO) at different compositions has been studied by inverse gas chromatography (IGC). The adequacy of two molecule probes...

Polymerized polypeptide nanomicelles have attracted much attention as novel drug carriers because of their good biocompatibility and degradability. To prepare doxorubicin (DOX)-loaded nanomicelles, an amphiphilic peptide...

The resultsof studies of the effect of nature and parameters of particle size distribution of graphite on physical and mechanical properties of polymer composites based on aromatic polyamide fenіlon C-2. The particle si...

The purpose of this work was to investigate the interaction of graphene-like nanoclusters with fragments of polymers of the same nature, but of a slightly different structure, for example, polyethylene (PE) and polypropy...

Aluminum alloys are commonly subjected to chromatization to improve adhesion and protect against corrosion. However, this process is harmful to health and the environment. In this context, hybrid organic–inorganic sila...

Diclofenaco foi associado a nanocápsulas e a nanoesferas, preparadas através do método de nanoprecipitação, utilizando poli(e -caprolactona) (PCL) ou Eudragit S90® (EUD) como polímeros. As suspensões obtidas fora...

Tesis Energía y Ambiente (maestría) - Instituto Tecnológico de Buenos Aires, Buenos Aires - Karlsruher Institut für Technologie, Karlsruhe, 2024 "Fibre reinforced polymers (FRP) used in outdoor applications are expos...

Hydrophilic matrix tablets were developed with acyclovir (ACV), using hypromelose and polyethylene oxide (PEO) in different concentrations. Matrix tablets obtained in each formulation were evaluated to determine the weig...

Tesis de Licenciatura La fiebre chikungunya es una enfermedad causada por el virus Chikungunya (CHIKV) que genera síntomas inflamatorios y debilitantes (artralgia, artritis y mialgia). Esta enfermedad es transmitida por...

Free films were obtained by the combination of a polymer EudragitTM FS30D and oligosaccharides (alpha or gamma-CDs), by a casting process. The films were characterized by DSC, TGA, FTIR and SEM. The influence of composit...

The goal of any drug delivery system is to provide a therapeutic amount of drug (s) to the proper site in the body in order to promptly achieve and there by to maintain the desired drug concentrations during treatment. T...

Benzocaine (BZC) is an ester-type local anesthetic used mainly in topical, dermal and mucosal formulations. The present work consists of the development and validation of analytical methodology for evaluation of benzocai...

A set of oligonucleotide primers capable of initiating enzymatic amplification (polymerase chain reaction) on a phylogenetically and taxonomically wide range of bacteria is described along with methods for their use and ...

Use of the real-time polymerase chain reaction (PCR) to amplify cDNA products reverse transcribed from mRNA is on the way to becoming a routine tool in molecular biology to study low abundance gene expression. Real-time ...

A new method for determining nucleotide sequences in DNA is described. It is similar to the "plus and minus" method [Sanger, F. & Coulson, A. R. (1975) J. Mol. Biol. 94, 441-448] but makes use of the 2',3'-dideoxy and ar...

We have developed a novel method, termed loop-mediated isothermal amplification (LAMP), that amplifies DNA with high specificity, efficiency and rapidity under isothermal conditions. This method employs a DNA polymerase ...
