Effect of a cajuína hydroelectrolytic drink on the physical performance and hydration status of recreational runners.

Cajuína is a processed drink derived from cashew and is widely consumed in the northeast region of Brazil. This study evaluated the effect of a cajuína-based hydroelectrolytic drink on the aerobic performance and hydration status of recreational runners. Seventeen males (31.9 ± 1.6 years, 51.0 ± 1.4 ml/kg/min) performed three time-to-exhaustion running sessions on a treadmill at 70% VO2max, ingesting cajuína hydroelectrolytic drink (CJ), high carbohydrate commercial hydroelectrolytic drink (CH) and mineral water (W) every 15 min during the running test. The participants ran 80.3 ± 8.4 min in CJ, 70.3 ± 6.8 min in CH and 71.8 ± 6.9 min in W, with no statistical difference between procedures. Nevertheless, an effect size of η2 = 0.10 (moderate) was observed. No statistical difference was observed in the concentrations of sodium, potassium, and osmolality in both serum and urine between the three conditions. However, the effect size was moderate (urine sodium) and high (serum sodium, potassium, and osmolality). Urine specific gravity, sweating rate and heart rate were not significantly different between drinks. The cajuína-based hydroelectrolytic drink promotes similar effects compared to commercial hydroelectrolytic drink and water, considering specific urine gravity, heart rate, sweating, and time to exhaustion in recreational runners.

Nanoparticles Obtained from Zein for Encapsulation of Mesalazine.

We encapsulated MSZ in zein nanoparticles (NP-ZN) using a desolvation method followed by drying in a mini spray dryer. These nanoparticles exhibited a size of 266.6 ± 52 nm, IPD of 0.14 ± 1.1 and zeta potential of -36.4 ± 1.5 mV, suggesting colloidal stability. Quantification using HPLC showed a drug-loaded of 43.8 µg/mg. SEM demonstrated a spherical morphology with a size variation from 220 to 400 nm. A FTIR analysis did not show drug spectra in the NPs in relation to the physical mixture, which suggests drug encapsulation without changing its chemical structure. A TGA analysis showed thermal stability up to 300 °C. In vitro release studies demonstrated gastroresistance and a sustained drug release at pH 7.4 (97.67 ± 0.32%) in 120 h. The kinetic model used for the release of MSZ from the NP-ZN in a pH 1.2 medium was the Fickian diffusion, in a pH 6.8 medium it was the Peppas-Sahlin model with the polymeric relaxation mechanism and in a pH 7.4 medium it was the Korsmeyer-Peppas model with the Fickian release mechanism, or "Case I". An in vitro cytotoxicity study in the CT26.WT cell line showed no basal cytotoxicity up to 500 µg/mL. The NP-ZN showed to be a promising vector for the sustained release of MSZ in the colon by oral route.

Poly(Alizarin Red S) on pyrolytic graphite electrodes as a new multi-electronic system for sensing oxandrolone in urine.

This study presents a new polymeric and multielectronic system, the poly-Alizarin Red S (PARS), obtained from the electropolymerization of Alizarin Red S (ARS) dye on an edge-plane pyrolytic graphite electrode (EPPGE) surface. During EPPGE/PARS electrochemical characterization, we identified seven stable and reversible redox peaks in acidic medium (0.10 mol L-1, pH 1.62 KH2PO4), which indicated its mechanisms underlying electropolymerization and electrochemical behavior. To the best of our knowledge, this is the first study to use an EPPGE/PARS electrode to detect oxandrolone (OXA) in artificial urine, where PARS acts as a synthetic receptor for OXA. The interactions of OXA with EPPGE/PARS as well as the properties of PARS were investigated using density functional theory (DFT). Atomic force microscopy (AFM) was used to characterize EPPGE/PARS, and it was found that the PARS polymer formed a semi-globular phase on the EPPGE surface. The limit of detection for OXA found by the sensor was close to 0.50 nmol L-1, with a recovery rate of approximately 100% in artificial urine. In addition to the application proposed in this study, EPPGE/PARS is a low-cost product that could be applied in several devices and processes, such as supercapacitors and electrocatalysis.

Cashew-gum-based silver nanoparticles and palygorskite as green nanocomposites for antibacterial applications.

Nanocomposite materials have been proposed to enhance the properties of different materials. In this study, palygorskite (Pal) clay is proposed as a support matrix for silver nanoparticles stabilised with cashew gum (Anacardium occidentale L.) (AgNPs-CG), producing the Pal/AgNPs-CG nanocomposite, whose bactericidal activity was studied. AgNPs-CG was synthesised using a green method in which CG acted as a reducing and stabilising agent for these nanostructures. AgNPs-CGs were subsequently characterised then adsorbed to the Pal surface, which was previously treated to remove impurities such as quartz. Pal and Pal/AgNPs-CG were characterised by X-ray diffraction, specific surface area, thermal analysis, Fourier transform infrared spectroscopy, scanning electron microscopy, energy dispersive spectroscopy, and transmission electron microscopy. The antibacterial activity assay by the direct contact method showed that the synergistic effect of the combination of AgNPs-CG and Pal increased the bactericidal effect of the nanomaterial compared with the AgNPs-CG activity, reaching a percentage inhibition of up to 70.2% against E. coli and 85.3% against S. aureus. Nanocomposite atoxicity was demonstrated by the Artemia Salina model. Thus, the Pal/AgNPs-CG nanocomposite emerges as a nanomaterial with potential antibacterial applications.

Ethyl ferulate/ß-cyclodextrin inclusion complex inhibits edema formation.

Ethyl ferulate, a phenylpropanoid derived from rice hulls has aroused interest because of its antioxidant, anti-inflammatory and neuroprotective properties. However, it has low solubility in water which compromises the absorption in the gastrointestinal tract, decreases the bioavailability and compromises the reproducibility of the effects in vivo. To increase the solubility of ethyl ferulate, inclusion complexes were obtained by physical mixing, malaxing, lyophilization and spray drying and characterized using thermal analysis, XRD and FTIR. The complexes obtained were evaluated for ethyl ferulate content, stability, dissolution profile and evaluation of anti-inflammatory activity in vivo through carrageenan-induced paw edema model in rats. The inclusion complexes obtained resulted in increased solubility and stability compared to the isolated ethyl ferulate. In addition, the complexes obtained by malaxage, lyophilization and spray drying showed greater inhibition of the edema formation induced by carrageenan compared to ethyl ferulate 100 mg/kg v.o. The inclusion of ethyl ferulate in B-cyclodextrin resulted in the formation of stable inclusion complexes with potent antidematogenic activity possibly attributed to the increased solubility, dissolution profile of the active.

Systematic review and technological prospection: ethyl ferulate, a phenylpropanoid with antioxidant and neuroprotective actions.

INTRODUCTION: Ethyl ferulate is a phenylpropanoid with anti-inflammatory, antioxidant and neuroprotective activities of natural and synthetic origin with potential uses in the nutraceutical and pharmaceutical industry. Therefore, the aim of this study was to investigate the current scenario regarding patents and scientific articles available involving the substance in question, regarding aspects such as quantity, areas of knowledge and depositor countries. AREAS COVERED: To do so, we conducted technological and scientific prospecting on the WIPO, EPO, USPTO and INPI and scientific databases in PubMed, Web of Science and Lilacs databases using the keywords 'ferulic acid ethyl ester' and 'ethyl ferulate' in English and Portuguese. A total of 16 articles and 17 patents of which 10 were Chinese and 11 claimed the use of ethyl ferulate or for the synthesis of other substances or synthetic methods of the same. Five of the patents selected claimed therapeutic applications related to the treatment of mycobacterial infections, use as a cosmetic and neuroprotective activity. The systematic review of the literature revealed antioxidant, neuroprotective, anti-inflammatory, antimutagenic, antiapoptotic, antimutagenic and antiproliferative activities. EXPERT OPINION: The technological and scientific prospection highlighted ethyl ferulate, despite its known pharmacological activities, is little explored by the pharmaceutical and nutraceutical industries.

Development of a low-cost electrochemical sensor based on babassu mesocarp (Orbignya phalerata) immobilized on a flexible gold electrode for applications in sensors for 5-fluorouracil chemotherapeutics.

There are increasing concerns regarding the risks arising from the contamination of manipulators of antineoplastic drugs promoted by occupational exposure or even in the dosage of drugs. The present work proposes the use of an electrochemical sensor based on a biopolymer extracted from the babassu coconut (Orbignya phalerata) for the determination of an antineoplastic 5-fluorouracil (5-FU) drug as an alternative for the monitoring of these drugs. In order to reduce the cost of this sensor, a flexible gold electrode (FEAu) is proposed. The surface modification of FEAu was performed with the deposition of a casting film of the biopolymer extracted from the babassu mesocarp (BM) and modified with phthalic anhydride (BMPA). The electrochemical activity of the modified electrode was characterized by cyclic voltammetry (CV), and its morphology was observed by atomic force microscopy (AFM). The FEAu/BMPA showed a high sensitivity (8.8 µA/µmol/L) and low limit of detection (0.34 µmol/L) for the 5-FU drug in an acid medium. Electrochemical sensors developed from the babassu mesocarp may be a viable alternative for the monitoring of the 5-FU antineoplastic in pharmaceutical formulations, because in addition to being sensitive to this drug, they are constructed of a natural polymer, renewable, and abundant in nature.

These drugs have several side effects. The objective of this study was to perform a systematic review on the transdermal administration of drugs and the use of alternative therapies for the treatment of PD. AREAS COVERED: The article bases were Web of Science, PubMed and Sciencedirect and the patent bases were INPI, EPO and WIPO with publications on Primary Dysmenorrhea and associations with Transdermal Administration; Complementary Therapies and Medicinal Plants. 21 articles and 12 patents were analyzed. The results demonstrate the need for alternative therapies for the treatment of PD, with greater effectiveness and lower side effects, mainly in an attempt to reduce the intensity and duration of pain as well as reducing the continuous use of medications. EXPERT OPINION: The study of technological prospection highlighted the relevant importance in seeking new methods for the relief of the symptoms provoked by this condition. The perspectives coexist in the discovery of new natural and biotechnological pharmacological applications, mainly in the development of new devices capable of facilitating and optimizing this form of administration in an attempt to reduce side effects.

Simultaneous Quantification of Benznidazole and Posaconazole by HPLC-DAD Using QbD Approach.

OBJECTIVE: To develop an analytical method to simultaneous quantification of benznidazole (BNZ) and posaconazole (POS) by high-performance liquid chromatography with diode-array detection (HPLC-DAD) using design of experiments. METHODS: Percentages of organic phase, buffer pH and flow rates of mobile phase were selected as independent variables by full factorial design (33), totaling 27 experiments. Significant factors were evaluated using factorial analysis of variance with 95% confidence level. Method optimization was performed using desirability profiles, considering BNZ/POS chromatographic resolution and peak areas. Further, the method was evaluated regarding its suitability and properly validated according to the international compendiums using the parameters: specificity, linearity, accuracy, precision, limit of detection and limit of quantification. RESULTS: The optimized method was achieved using Discovery® C8 column (250 mm × 4.6 mm; 5 µm particle size), methanol/acetate buffer (pH 3.5)(71:29) and detection at 260 nm. Retention times were 3.6 and 7.6 min for BNZ and POS, respectively, with good suitability of system and it was specific and linear (r2 >0.99) for both drugs, proving the efficiency of the method even in the presence of degradation products of POS. CONCLUSION: This new method is a great alternative to perform reliable, faster and cheaper analysis since the simultaneous quantification of the association BZN/POS is not reported yet in the literature.

Electrochemical sensors and biosensors for the analysis of antineoplastic drugs.

Cancer is a leading cause of death worldwide, often being treated with antineoplastic drugs that have high potential for toxicity to humans and the environment, even at very low concentrations. Therefore, monitoring these drugs is of utmost importance. Among the techniques used to detect substances at low concentrations, electrochemical sensors and biosensors have been noted for their practicality and low cost. This review brings, for the first time, a simplified outline of the main electrochemical sensors and biosensors developed for the analysis of antineoplastic drugs. The drugs analyzed and the methodology used for electrochemical sensing are described, as are the techniques used for drug quantification and the analytical performance of each sensor, highlighting the limit of detection (LOD), as well as the linear range of quantification (LR) for each system. Finally, we present a technological prospection on the development and use of electrochemical sensors and biosensors in the quantification of antineoplastic drugs. A search of international patent databases revealed no patents currently submitted under this topic, suggesting this is an area to be further explored. We also show that the use of these systems has been gaining prominence in recent years, and that the quantification of antineoplastic drugs using electrochemical techniques could bring great financial and health benefits.

Lateral Flow Assay for Interleukin 6: A Technological and Scientific Prospection of a 10-Year Survey.

BACKGROUND: Interleukin-6 (IL-6) is a multifunctional cytokine that plays a crucial role not only in the immune system but also in numerous biological processes. Elevated IL-6 levels have been observed in many types of cancer and inflammatory diseases. Among the techniques that have been used to quantify IL-6, a Lateral Flow Assay (LFA) is one of the most promising. OBJECTIVE: The objective of this study was to perform a technological and scientific exploration of the development of an LFA for IL-6. METHOD: The Instituto Nacional de Propriedade Industrial-INPI (Brazil), European Patent Office - Espacenet, and United States Patent and Trademark Office-USPTO were used for the technological prospection to consider all the patents regarding an LFA for IL-6 detection. For the scientific investigation, the following periodic databases were used: Web of Science, Science Direct, PubMed, and Scielo, and were monitored from 2007 to May 2017. RESULTS: We found no patents based on the searched keywords, and a limited number of scientific articles were found. Therefore, the development of an LFA sensor for the detection of IL-6 appears to be innovative with significant biotechnological importance, creating a technology transfer to promote economic and industrial growth. CONCLUSION: The development of lateral flow immunosensors for IL-6 is innovative, as we could not find patents describing such a biosensor. Scientific prospection reported two lateral flow immunosensors. However, the test for IL-6 cannot be completed without using some kind of equipment for detection, such as the one we propose in future developments.

Pharmaceutical development of tablets containing a spray-dried optimized extract from Lippia origanoides H. B. K.: influence of excipients and toxicological assessment

ABSTRACT Lippia origanoides is a honey shrub which has showed hypotensive potential assessed by in vivo studies. The aim of this work is the development of a pharmaceutical formulation composed by an optimized extract obtained from aerial parts of L. origanoides. The quantification of the naringenin marker in the dry extract and tablets developed was performed, as well as the assessment of the oral acute toxicity in rats. The hydroalcoholic extract of L. origanoides was spray-dried with the addition of colloidal silicon dioxide (Lo-HAE/CSD), and then applied in the preparation of eight different lots of tablets. The influence of the diluent (cellulose or babassu mesocarp), the presence of binder, and the percentage of lubricant, as well as organoleptic and physicochemical characteristics were screened. For the quantification of the marker content both in Lo-HAE/CSD and in the tablets, an analytical curve of the naringenin standard was fitted, and the samples were then analyzed in UFLC. The toxicological assessment was performed in female Wistar rats according to the Acute Toxic Class Method from OECD. The developed tablets produced meet acceptable macroscopic characteristics, and the presence of babassu as diluent provided improved physicochemical properties. The best content of Lo-HAE/CSD in the tablet (100.27%) was identified for the lot containing babassu, composed by 1.0% magnesium stearate, without PVP binder in its formulation. Moreover, Lo-HAE/CSD showed no signs of toxicity. Therefore, the babassu mesocarp powder is a promising pharmaceutical excipient for the development of herbal tablets containing the Lippia origanoides extract.

Obtaining the palygorskite:chitosan composite for modified release of 5-aminosalicylic acid.

This study's aim was to obtain composites from palygorskite (PLG) and chitosan (CS) in order to modify 5-aminosalicylic (5-ASA) release. Initially, the PLG:CS composite was obtained using glutaraldehyde (GLA) as a reticular agent. Then, PLG, CS and PLG:CS were characterized by means of analytical techniques such as CHN elemental analysis, surface area analysis, XRD, FTIR, DSC and TG, SEM, adsorption tests and release profiles. Based on analytical data, the formation of the PLG:CS composite which showed the presence about 19% of CS, decrease in specific surface area, morphological analysis modified, visible change of crystallinity, of FTIR and thermal analysis. In relation to the drug-composite interaction, PLG:CS exhibited a significant increase in adsorption with 5-ASA at 58.24% in relation to PLG and CS which were at 16.29% and 23.96% respectively. The release profiles show that the PLG:CS composite changed the 5-ASA release speed in analyzed simulated fluids (intestinal and stomach) unlike other systems. Thus, the PLG:CS composite with proven synergy of the PLG and CS inherent properties showing 5-ASA effective modified release. Hence, this composite has potential benefits for the vectorization of drugs.

Chitosan Hydrogel in combination with Nerolidol for healing wounds.

Chitosan is a natural polymer with antibacterial property, that is biodegradable, extremely abundant and non-toxic. This study aimed to develop and characterize chitosan hydrogels in combination with nerolidol, in order to optimize the antimicrobial and healing properties. The hydrogels were prepared using a reaction of the chitosan with acetic acid solution, followed by the addition of 2 or 4% of the nerolidol. Using thermogravimetry, differential scanning calorimetry and infrared spectroscopy, the incorporation of nerolidol in the hydrogel was confirmed. Direct contact tests using hydrogels and Staphylococcus aureus showed a synergistic effect in the materials, enabling total inhibition of bacterial growth. The hydrogel containing 2% nerolidol showed excellent healing effects. The beginning of re-epithelialization and reorganization of collagen was already observed on the 7th day of treatment. The material created proofed to be promising as a healing and antibacterial agent.

Acetylated cashew gum-based nanoparticles for transdermal delivery of diclofenac diethyl amine.

Nanoprecipitation and dialysis methods were employed to obtain nanoparticles (NPs) of acetylated cashew gum (ACG). NPs synthesized by dialysis showed greater average size compared to those synthesized by nanoprecipitation, but they presented improved stability and yield. NPs were loaded with diclofenac diethylamine and the efficiency of the drug incorporation was over 60% for both methods, for an ACG:NP a weight ratio of 10:1. The cytotoxicity assay demonstrated that the NPs had no significant effect on the cell viability, verifying their biocompatibility. The release profile for the diclofenac diethylamine associated with the ACG-NPs showed a more controlled release compared to the free drug and a Fickian diffusion mechanism was observed. Transdermal permeation reached 90% penetration of the drug.
