Cold extraction process for producing a low-alcohol beer, International Pale Lager style: Evaluation and description of flavors using electronic tongue.

Grains germinate, dry, and then undergo crushing before being combined with hot water to yield a sweet and viscous liquid known as wort. To enhance flavor and aroma compounds while maintaining a lower alcohol content, cold water is utilized during wort production without increasing its density. Recent years have witnessed a surge in demand for beverages with reduced alcohol content, reflecting shifting consumer preferences towards healthier lifestyles. Notably, consumers of low-alcohol beers seek products that closely mimic traditional beers. In response, batches of low-alcohol beer were meticulously crafted using a cold extraction method with room temperature water, resulting in a beer with 1.11% alcohol by volume (ABV). Sensory evaluations yielded a favorable score of 27 out of 50, indicating adherence to style standards and absence of major technical flaws. Furthermore, electronic taste profiling revealed a striking similarity between the low-alcohol beer and the benchmark International Pale Lager style, exemplified by commercial beers (5 and 0.03% ABV). Notably, the reduced-alcohol variant boasted lower caloric content compared to both standard and non-alcoholic counterparts. Consequently, the cold extraction approach emerges as a promising technique for producing low-alcohol beers within the International Pale Lager style, catering to evolving consumer preferences and health-conscious trends.

Oogenesis and in vitro reproduction of the twospot astyanax Astyanax bimaculatus (Linnaeus, 1758) exposed to conspecific alarm substance.

Stress situations can be essential to trigger reproduction in fish; however, it may also inhibit it. One of those situations involves the release of the conspecific alarm substance (CAS), a natural stressor, into the water by specific fish epidermal cells after a predator attack. Little is known about the effects of that substance on fish reproduction. This study aimed to evaluate the effects of CAS exposure on the oogenesis and reproduction of the twospot astyanax Astyanax bimaculatus before the hormonal induction for artificial reproduction. No macroscopic or cellular changes in the ovaries were observed for the females exposed to CAS, and the oocyte stages show all females in the same phase of maturation (Spawning Capable). Females exposed to CAS spawned 20 min before the females without exposure. On the other hand, they ovulated only once, whereas the females from the control group ovulated multiple times for approximately two hours after hormonal induction. Moreover, the precocious ovulation of the females submitted to CAS did not generate offspring, since all generated zygotes did not develop. In contrast, the control group females produced more than 11 thousand healthy larvae. Exposing the female fish to CAS during their reproductive management in captivity may reduce breeding success.

Comparison of different types of phacoemulsification tips. III. Morphological changes induced after multiple uses in an ex vivo model.

PURPOSE: To assess the ultrastructural morphologic changes in the surface's micro-roughness for single-use and multiple-use phaco tips after multiple phacoemulsification cycles in an ex vivo animal model. SETTING: John A. Moran Eye Center and Utah Nanofab, College of Engineering, University of Utah, Salt Lake City, Utah, USA. DESIGN: Experimental study. METHODS: Eight types of phaco tips were studied using an identical experimental protocol. Two tips of each type were used to emulsify porcine cataractous lenses of moderate hardness for 2 minutes. This cycle was then repeated 5 consecutive times for each phaco tip. Scanning electron microscopy and white-light interferometry were used to analyze each tip for potential ultrastructural damage. RESULTS: No significant structural damage was noted on either single- or multiple-use tips after 5 cycles of experimental use. There was a trend toward increased surface micro-roughness at the tip opening after multiple procedures. Most tips had salt crystals on their surface and deposits of organic material composed of carbon and oxygen, which were consistent with porcine tissue that had not been cleaned from the tip surface. CONCLUSIONS: No significant ultrastructural damage was detected after repeated experimental use of phaco tips in a porcine cataract model. There was no significant difference when phaco tips labeled for single use or multiple uses were compared.

Convenient enzymatic resolution of (R,S)-2-methylbutyric acid catalyzed by immobilized lipases.

The application of several immobilized lipases has been explored in the enantioselective esterification of (R,S)-2-methylbutyric acid, an insect pheromone precursor. With the use of Candida antarctica B, using hexane as solvent, (R)-pentyl 2-methylbutyrate was prepared in 2 h with c 40%, eep 90%, and E = 35, while Thermomyces lanuginosus leads to c 18%, eep 91%, and E = 26. The (S)-enantiomer was obtained by the use of Candida rugosa or Rhizopus oryzae (2-h reaction, c 34% and 35%, eep 75 and 49%, and E = 10 and 4, respectively). Under optimal conditions, the effect of the solvent, the molar ratio, and the nucleophile were evaluated.

Michel Foucault e a revolução narrativa em psicopatologia e psicoterapia: ser-em-estórias entre pathos e poiesis / Michel Foucault and the narrative revolution in psychopathology and psychotherapy: Being-in-stories between pathos and poiesis / Michel Foucault et la révolution narrative en psychopathologie et psychothérapie: être-dans-des-histoires entre pathos et poiesis / Michel Foucault y la revolución narrativa en psicopatología y psicoterapia: ser-en-historias entre pathos y poiesis

O modelo narrativo em psicopatologia e psicoterapia, com dinamismo crescente desde a proposta inicial de White e Epston (1990), afirma-se como crítica "discursiva" não somente das categorias de diagnóstico psicopatológico, mas também da assimetria cognitiva e prática na relação psicoterapêutica. Neste artigo, examinamos os fundamentos epistemológicos desse modelo, recorrendo a Michel Foucault para examinar os processos simbólicos de criação narrativa da subjetividade.

The narrative model in psychopathology and psychotherapy, increasing dynamic since the initial proposal of White and Epston (1990), reaffirms itself as a "discursive" critique of psychopathological diagnosis categories, as well as of cognitive and practical asymmetry within the psychotherapeutical relationship. In this paper, we examine the epistemological foundations of this model, turning to Michel Foucault to examine the symbolic processes inherent to the narrative creation of subjectivity.

Le modèle narratif de la psychopathologie et de la psychothérapie, dont le dynamisme s'intensifie depuis White et Epston (1990), s'affirme comme une critique discursive des catégories de diagnostic psychopathologique, ainsi que de l'asymétrie cognitive et de la pratique du rapport psychothérapeutique. Cet article examine les fondements épistémologiques de ce modèle et analyse, avec Michel Foucault, les processus symboliques de la création narrative de la subjectivité.

Das narrative Modell der Psychopathologie und Psychotherapie, dessen Dynamik seit White und Epston (1990) zugenommen hat, versteht sich als 'diskursive' Kritik der diagnostischen Kategorien von psychischen Störungen, sowie der kognitiven und praktischen Asymmetrie der therapeutischen Beziehung. In diesem Artikel untersuchen wir die Grundlagen dieses Modells und analysieren, unter Bezugnahme von Michel Foucaults Theorie, die symbolischen Prozesse der narrativen Schaffung von Subjektivität.

Pyonephrosis caused by Salmonella sp. in a patient with polycystic kidney disease undergoing hemodialysis / Pionefrose causada por Salmonella sp. em um paciente com doença renal policística submetido a hemodiálise

AIMS: This article reports a case of pyonephrosis caused by Salmonella sp. in a patient with polycystic kidney disease undergoing hemodialysis treatment. CASE DESCRIPTION: An elderly male patient previously diagnosed with polycystic kidney disease undergoing standard hemodyalitic treatment presented uronephrosis, evolving to pyonephrosis caused by Salmonella sp., and was successfully treated with ciprofloxacin. CONCLUSIONS: The polycystic kidney disease may have contributed to the bacteria's attachment to the kidney, due to increase of permeability of the intestinal mucosa, easier bacterial translocation to bloodstream and its subsequent accommodation in the infected organ.

OBJETIVOS: Este artigo relata um caso de pionefrose causada por Salmonella sp. em paciente com doença renal policística em tratamento por hemodiálise. DESCRIÇÃO DO CASO: Um paciente idoso do sexo masculino, previamente diagnosticado com doença renal policística, em tratamento convencional por hemodiálise, apresentou uronefrose, evoluindo a pionefrose causada por Salmonella sp., sendo tratado com sucesso com ciprofloxacino. CONCLUSÕES: A doença renal policística pode ter contribuído para a instalação da bactéria no rim, visto o aumento da permeabilidade da mucosa intestinal e maior facilidade de translocação da bactéria para a corrente sanguínea e seu posterior alojamento no órgão infectado.

Comparison of different types of phacoemulsification tips. I. Quantitative analysis of elemental composition and tip surface microroughness.

PURPOSE: To evaluate the elemental composition of phacoemulsification tips and their surface roughness in the microscale. SETTING: John A. Moran Eye Center and Utah Nanofab, College of Engineering, University of Utah, Salt Lake City, Utah, USA. DESIGN: Experimental study. METHODS: Seven types of phacoemulsification tips were studied. The phaco tips were examined through energy-dispersive x-ray spectroscopy (EDS) and x-ray photoelectron spectroscopy (XPS) for elemental composition. In addition, the roughness of the opening in all tips was assessed through 3-dimensional white-light interferometry. RESULTS: Elemental analysis showed considerable differences in the surface layers between manufacturers. Alcon tips had a thinner oxidized titanium (Ti) layer in their surface. Through XPS, vanadium was not detected in the superficial layers of any tip, but only in deeper levels. The microroughness surface analysis showed comparable results regarding their root-mean-square (RMS) metric. Maximum peak valley distance values varied and appeared to be dependent on the quality of material process rather than the material itself. CONCLUSIONS: Phacoemulsification tips are made of Ti alloys and showed differences between models, especially regarding their composition in the superficial layers. Their opening end roughness showed an overall appropriate RMS value of less than 1.0 µm in all cases. The existence of small defected areas highlights the importance of adequate quality control of these critical surgical instruments.

Comparison of different types of phacoemulsification tips. II. Morphologic alterations induced by multiple steam sterilization cycles with and without use of enzyme detergents.

PURPOSE: To evaluate the alterations in the morphology and elemental composition of reusable phacoemulsification tips after cleaning and sterilization. SETTING: John A. Moran Eye Center, Salt Lake City, Utah, USA. DESIGN: Experimental study. METHODS: For the main experiment, 2 types of reusable phacoemulsification needles were studied. One tip of each type underwent 1, 2, and 3 autoclave sterilizations with the use of detergents followed by thorough rinsing with sterile water between cycles. Another set of tips underwent the same procedure but without rinsing. Subsequently, phaco tips were examined through scanning electron microscopy and energy-dispersive x-ray spectroscopy to assess morphologic changes and surface deposits. In a second experiment, tips of 8 different types (both reusable and single use) underwent 10 sterilization autoclave cycles without detergents. RESULTS: Residues, mostly comprised of carbon-containing material, were found in extensive areas of tips that were sterilization with enzymes and without rinsing. Smaller and fewer residues were found in tips after sterilization with the use of enzymes and thorough rinsing. Tips that underwent autoclave sterilization without detergents had no bulky deposits on their surface; they mostly had thin layers of sodium and chloride or material discoloration. CONCLUSIONS: Rinsing the phaco tips significantly reduced the size and number of residues after use of enzymatic detergents. However, detergent residues were detected on phaco tip surfaces even after thorough rinsing with sterile water. No major noticeable changes were observed in either single-use or reusable phaco tips after 10 cycles of sterilization without detergents. FINANCIAL DISCLOSURE: None of the authors has a financial or proprietary interest in any material or method mentioned.

Atualização sobre ultrassom doppler das artérias vertebrais: síndrome do roubo da subclávia / An update on doppler ultrasound of vertebral arteries: subclavian steal syndrome

A síndrome do roubo da subclávia refere-se a uma desordem vascular na qual ocorre inversão do fluxo de sangue da artéria vertebral ipsilateral, decorrente de uma estenose proximal à sua origem, geralmente uma oclusão da artéria subclávia ou, mais raramente, do troncobraquiocefálico. É uma doença relativamente rara, relatadaem aproximadamente 6% dos pacientes assintomáticos com sopros cervicais. O Doppler pulsado (PW) é útil na análiseda artéria vertebral, registrando informações capazes de identificar a presença da Síndrome do Roubo da Subclávia. Com base nas alterações hemodinâmicas da artéria vertebralavaliadas pelo estudo com Doppler espectral, pode ser classificada nos tipos 1 (oculto), 2 (intermitente ou parcial)e 3 (completo). Com o advento da angioplastia transluminal percutânea e, em seguida, dos stents, muitos advogam essa combinação de procedimentos como o tratamento de escolha dos casos sintomático dessa síndrome.

Efeitos do exercício muscular respiratório na biomecânica da deglutição de indivíduos normais / Effects of muscle respiratory exercise in the biomechanics of swallowing of normal individuals

RESUMO: Objetivo: analisar os efeitos do exercício respiratórios na biomecânica da deglutição de sujeitos normais. Métodos: o exercício muscular respiratório em sujeitos normais foi aplicado por sete dias consecutivos por meio de incentivador respiratório a fluxo (três séries de dez repetições para inspiração e expiração). A biomecânica da deglutição foi avaliada por videofluoroscopia, utilizando variáveis temporais (tempo de transição faríngea) e visuoperceptuais (número de deglutições, resíduos em seios piriformes e valéculas, penetração/aspiração). Para análise estatística foi aplicado o Teste de Wilcoxon, Igualdade de Duas Proporções e Kappa. Resultados: foram avaliadas 16 jovens do sexo feminino com média de idade de 21,2±3,4 anos. Nas variáveis visuoperceptuais observou-se concordância quase perfeita entre os avaliadores (p<0,001), bem como na temporal (p = 1,00). Após o período de treinamento houve redução no tempo de transição faríngea (p=0,02). Conclusão: o uso de incentivador respiratório a fluxo influenciou significantemente na biomecânica da deglutição, principalmente na redução do tempo de transição faríngea.

ABSTRACT: Purpose: to analyze the effects of the respiratory exercise in the biomechanics of swallowing in normal subjects. Methods: the muscle respiratory exercise in normal subjects was performed for seven consecutive days by the incentive spirometer flow (three sets of ten repetitions for inspiration and expiration).The biomechanics of swallowing was evaluated by video fluoroscopy through temporal variables (pharyngeal transition time) and visual-perceptual (number of swallows, waste in the pyriform sinuses and vallecula, penetration/aspiration). For statistical analysis, the Wilcoxon test, Equality of Two Proportions and Kappa were used. Results: 16 young women with a mean age of 21,2±3,4 years were evaluated. In visual-perceptual variables it was observed almost perfect agreement between evaluators (p<0,001) and in temporal variable (p=1,00). After the training period there was a significant reduction in the pharyngeal transition time (p=0,02). Conclusion: the use of incentive spirometer flow significantly influenced the biomechanics of swallowing, especially in reducing the pharyngeal transition time.

Binding of alkenes and ionic liquids to B-H-functionalized boron nanoparticles: creation of particles with controlled dispersibility and minimal surface oxidation.

The interaction of B-H-functionalized boron nanoparticles with alkenes and nitrogen-rich ionic liquids (ILs) is investigated by a combination of X-ray photoelectron spectroscopy, FTIR spectroscopy, dynamic light scattering, thermogravimetric analysis, and helium ion microscopy. Surface B-H bonds are shown to react with terminal alkenes to produce alkyl-functionalized boron particles. The interaction of nitrogen-rich ILs with the particles appears, instead, to be dominated by boron-nitrogen bonding, even for an ILs with terminal alkene functionality. This chemistry provides a convenient approach to producing and capping boron nanoparticles with a protective organic layer, which is shown to protect the particles from oxidation during air exposure. By controlling the capping group, particles with high dispersibility in nonpolar or polar liquids can be produced. For the particles capped with ILs, the effect of particle loading on hypergolic ignition of the ILs is reported.

Instituições de Longa Permanência para Idosos como espaço socioeducacional: desafios e perspectivas / Long-stay Institution for the Elderly as an socioeducational space: challenges and prospects

Instituição de Longa Permanência para Idosos (ILPI) não é uma questão nova no Brasil. Essa modalidade institucional, entretanto, necessitou ser expandida devido ao aumento significativo da população idosa, e ser reconfigurada em suas funções dadas as mudanças na família brasileira, o que se torna de grande valia tentar compreender seu funcionamento atual. O objetivo deste estudo qualitativo, de caráter descritivo, é analisar o sentido socioeducacional de uma ILPI ­ uma formulação problematizada e dinâmica da articulação entre traços relevantes do perfil de seus residentes e do perfil de profissionais que nela atuam. O desenvolvimento da pesquisa se deu por meio de revisão bibliográfica e análise documental na área das Ciências Humanas e da Saúde, incluindo publicações em mídia digital. Os resultados das análises destacam a questão do entendimento sobre o cuidado, em particular aquele que passou a ser exigido de uma ILPI: o cuidado continuado para o acolhimento e atendimento de um idoso dependente ou aquele egresso de hospitalização. Isso demanda a capacitação de seus profissionais para um adequado desempenho na função diante do perfil desses idosos, muitos sem apoio familiar ou de uma rede social.

Long-stay institution for the elderly (LTCF) is not a new issue in Brazil. This institutional mode, however, needed to be expanded due to the significant increase in the elderly population, and reconfigured in its functions, given the changes in the Brazilian family, which becomes very useful to try to understand its current operation. The aim of this qualitative study of descriptive character, is to analyze the social and educational sense a LTCF - one problematised formulation and dynamic articulation of relevant features of the professional profile that her work and profile of its residents The development of the research was through literature review and document analysis in the area of Human and Health Sciences, including publications in digital media. The results of the analysis highlight the issue of understanding of care, in particular one that has come to be required of a LTCF: the Continuing Care for the reception and care of a newborn egress hospitalization elderly. This requires the training of its professionals for proper performance before the profile of the elderly, many without family support or a social network. The data reveal indicators of emotional availability, physical and mental those workers, working conditions, physical space and infrastructure of LTCF with a view to ensure equitable care and quality of care for older people.

Synthesis of nanoparticles from malleable and ductile metals using powder-free, reactant-assisted mechanical attrition.

A reactant-assisted mechanochemical method was used to produce copious nanoparticles from malleable/ductile metals, demonstrated here for aluminum, iron, and copper. The milling media is intentionally degraded via a reactant-accelerated wear process, where the reactant aids particle production by binding to the metal surfaces, enhancing particle production, and reducing the tendency toward mechanochemical (cold) welding. The mechanism is explored by comparing the effects of different types of solvents and solvent mixtures on the amount and type of particles produced. Particles were functionalized with oleic acid to aid in particle size separation, enhance dispersion in hydrocarbon solvents, and protect the particles from oxidation. For aluminum and iron, the result is air-stable particles, but for copper, the suspended particles are found to dissolve when exposed to air. Characterization was performed using electron microscopy, dynamic light scattering, Fourier transform infrared spectroscopy, solid state nuclear magnetic resonance, and X-ray photoelectron spectroscopy. Density functional theory was used to examine the nature of carboxylic acid binding to the aluminum surface, confirming the dominance of bridging bidentate binding.

Boron nanoparticles with high hydrogen loading: mechanism for B-H binding and potential for improved combustibility and specific impulse.

Ball milling of boron in an H2 atmosphere was found to result in hydrogen uptake of up to 5% by weight (36 mol %). The nature of the hydrogen binding to boron was probed by a combination of ab initio theory, IR spectroscopy, thermogravimetric analysis, and mass spectral measurements of gases evolved during sample heating. The dominant binding mode is found to be H atoms bound to B atoms in the surface layer of the particles, and the high hydrogen loading results from production of very high surface area, indicating that gaseous H2 is an effective agent promoting size reduction in milling. Hydrogen incorporated in the samples was found to be stable for at least a month under ambient conditions. Desorption is observed beginning at ∼60 °C and continuing as the temperature is increased, with broad desorption features peaking at ∼250 and ∼450 °C, and ending at ∼800 °C. Unprotected hydrogenated boron nanoparticles were found to be reactive with O2 producing a hydrated boron oxide surface layer that decomposed readily at 100 °C leading to desorption of H2O. Hydrogenated boron nanoparticles were found to promote a higher flame height in the hypergolic ignition of ionic liquids upon contact with nitric acid.

Pharyngeal swallowing phase and chronic cough

Introduction: The act of swallowing depends on a complex and dynamic process which uses common structures to the act of breathing; respiratory problems can cause swallowing difficulties. Aim: To assess the swallowing pharyngeal phase in patients with chronic cough. Method: Retrospective study with 15 patients of both genders, patients with chronic cough and risk factors for aspiration defined by the pneumologic diagnosis. The patients were submitted to anamnesis on complaints related to swallowing, chewing and breathing, or related to food and to videofluoroscopic examination. Results: It was observed that 33.3% had normal and functional swallowing, being the last one of most prevalence. The mild dysphagia was observed in 20% of the patients, the mild to moderate dysphagia in 6.7% of them. In relation to the Rosenbek scale, 73.3% of patients presented degree 1, 6.7% presented degrees 2 and 3, and 13.3% presented degree 8. The most found pathology was the chronic cough with 40%, followed by asthma with 20%; 69.2% of patients presented stasis and of these, five used protection maneuvers, of these, seven were effective and only three were used in the presence of stasis. The most used maneuver was the multiple swallowing, being effective in 100%. Conclusion: There are peculiarities in the patients' swallowing with chronic cough that, although not presenting complaints relating to swallowing, it presents an important aspiration risk due to the presence of changes in breathing pattern that can intervene in the coordination between breathing and swallowing, which is essential to protect the lower airway...

Tuning azolium azolate ionic liquids to promote surface interactions with titanium nanoparticles leading to increased passivation and colloidal stability.

The passivation and stability of suspensions of titanium nanoparticles in azolium azolate ionic liquids can be tuned by introducing metal specific binding sites in the azolate anion.

Hypergolic ionic liquids to mill, suspend, and ignite boron nanoparticles.

Boron nanoparticles prepared by milling in the presence of a hypergolic energetic ionic liquid (EIL) are suspendable in the EIL and the EIL retains hypergolicity leading to the ignition of the boron. This approach allows for incorporation of a variety of nanoscale additives to improve EIL properties, such as energetic density and heat of combustion, while providing stability and safe handling of the nanomaterials.
