Abstract The recently introduced one-step process to form double emulsions is analyzed using generalized phase diagrams of water, ethylene oxide adduct surfactants, and hydrocarbons. With the process used, we found three factors to be involved in the successful formation of double emulsions. Temporary ultra-low interfacial tension allowed drops of irregular shape to exist, a large part of the emulsion formed a bicontinuous microemulsion at intermediate times, and the interfacial tension was temporarily ...

Emulsions containing liquid crystals present interesting properties and advantages such as the skin moisturize increase, active release modulation, and emulsion stabilization. In this work, emulsions containing annatto, coffee and tea tree oils, and nonionic surfactants were developed. The HLB method was used for selection of surfactants. The required HLB value was established (9.0). Liquid crystals were attained when used the surfactant mixture Ceteareth‐5 and Steareth‐2 and identified as lamellar. ...

The effects of some composition variables on the development of multiple emulsions by one‐step method were evaluated and their morphology characterized. The formulations that remained stable during the period of the test were submitted to centrifugation and thermal stress tests. The stability and the morphology of multiple droplets were affected not only by the type and concentration of the surfactants employed, but also by the water/oil ratios used. The results suggest that the formation of multiple ...

Abstract Emulsion stability is controlled by the physicochemical properties of the adsorbed layers formed on the surface of the droplets. Zeta potential and droplet size measured initially and during storage can estimate O/W emulsion stability. The aim of this study was to characterize and evaluate the effects of different hydrolyzable compounds employed in pharmaceutical and cosmetic preparations on the zeta potential and droplet size of canola O/W nano‐emulsions and, consequently, the emulsion ...

Abstract O/W emulsions with liquid crystals are complex systems for the delivery of actives into the skin surface since they modulate the release rate in the structure, and they increase the stability and solubility of slightly soluble substances in oil or aqueous phase and support moisturing by decreasing the transepidermal water loss (TEWL). The development of emulsions with vegetable oils is interesting due to their properties; in addition it allows the use of natural raw materials of Brazil's ...

Depending on the emulsion preparation method, different droplet size distributions might be achieved. The EPI method (low‐energy emulsification method) works with water volume fraction changes. Nanometer emulsions can be obtained by this method. The aim of this work was to evaluate the canola oil‐water nano‐emulsion physicochemical characteristics: zeta potential and droplet size values upon preparation and after stability tests. The obtained outcomes suggest that nano‐emulsion yielded by EPI and ...

The chemical composition of the essential oil of the aerial parts of Microlicia graveolens DC., Melastomataceae, growing wild in the mountains of Minas Gerais, Brazil, was investigated for the first time. A pale orange to colourless oil was obtained in a yield of 4.8%. The oil was analyzed by GC-MS. The main components were (+)-trans-pinocarvyl acetate (78.9%), (-)-trans-pinocarvyl acetate (5.5%) and β-pinene (3.8%).

Because the real benefit of pulmonary valve replacement (PVR) in patients with repaired tetralogy of Fallot who develop pulmonary insufficiency remains unclear, it is necessary to analyze the evidence published around the world. We performed a systematic review of studies that reported data about the effect of PVR in patients with repaired tetralogy of Fallot that developed pulmonary insufficiency, until December 2012. The variables chosen to represent the benefit were both right ventricular (RV) ...

Massive testing to detect SARS-CoV-2 is an imperious need in times of epidemic but also presents challenges in terms of its concretization. The use of saliva as an alternative to nasopharyngeal swabs (NPS) has advantages, being more friendly to the patient and not requiring trained health workers, so much needed in other functions. This study used a total of 452 dual samples (saliva and NPS) of patients suspected of having COVID-19 to compare results obtained for the different specimens when using ...

In recurrent selection programs, progeny testing is done in multienvironment trials, which generates genotype × environment interaction (G × E). Therefore, modeling G × E is essential for genomic prediction in the context of recurrent genomic selection (RGS). Developing single‐step, best linear unbiased prediction‐based reaction norm models (termed RN‐HBLUP) using data from nongenotyped and genotyped progenies, can enhance predictive accuracy. Our objectives were to evaluate: (i) a class of RN‐HBLUP models ...

The present work focuses on the detection of SARS-CoV-2 in saliva, contributing to understanding the inhibition effect of the matrix and its influence on the results. Detection of viral genes ORF1ab, N, and E was performed by RT-PCR using saliva directly in the reaction without RNA extraction. Different amounts of saliva were spiked with increasing amounts of viral RNA from COVID-19 patients and subjected to RT-PCR detection. In parallel, 64 saliva samples from confirmed COVID-19 patients were used ...

The diagnosis of American Tegumentary Leishmaniasis is a difficult but essential task when considering the high toxicity profile of the drugs available. Since the discovery of its etiologic agent, numerous diagnostic tests have been developed. None of the tests available today can be considered as the gold standard, since they do not add enough accuracy for the disease detection. Good epidemiological and clinical knowledge of the disease are fundamental precepts of the dermatology practice and precede ...

The relative performance of one genotype is not identical in different environments due to genotype-environment interaction (G×E). Thus, for a breeding program to successfully develop cultivars, it is fundamental that candidate elite-lines are tested in several target environments and that the data are analysed for yield, adaptability and stability. The objective of this work was to study the G×E for upland rice using a mixed model and, using the harmonic mean of relative performance of genotypic ...

Melasma represents a pigmentary disorder that is difficult to treat. This study aims to broadly review the use of ablative lasers (Er:YAG and CO2) in the treatment of melasma, presenting the level of evidence of studies published to date. A total of 75 patients were enrolled in four case series studies (n=39), one controlled clinical trial (n=6) and one randomized controlled clinical trial (n=30). Studies on the Er:YAG laser showed better results with the use of short square-shaped pulses, which determined ...
