RESUMO

Honey is a very appreciated product for its nutritional characteristics and its benefits for human health, comprising antioxidant, anti-inflammatory, antifungal, and antibacterial activities. These attributes depend on the specific composition of each honey variety, with the botanical origin as one of the distinctive features. Indeed, honeydew and blossom honeys show different physicochemical properties, being the antioxidant capacity, mainly relying on the phenolic compound content, one of the most important. In this work, Folin-Ciocalteu (FC) index, total flavonoid content (TFC), and the antioxidant capacity based on the ferric reducing antioxidant power (FRAP) assay were determined for a total of 73 honeys (50 blossom honeys and 23 honeydew honeys). Mean content of oxidizable species (FC index) ranges from 0.17 to 0.7 mg eq. gallic acid g-1, with honeydew honeys being the ones with higher values. Regarding TFC, mean values above 1.5 mg eq. quercetin g-1 (method applied in the absence of NaNO2) were obtained for honeydew honeys and heather honey. Lower and not discriminatory values (below 0.3 mg eq. epicatechin g-1) were obtained in the presence of NaNO2. The maximum antioxidant capacity was observed for thyme honeys (2.2 mg eq. Trolox g-1) followed by honeydew and heather honeys. Individually, only the FC index was able to discriminate between honeydew and blossom honeys, while the other spectroscopic indexes tested allowed the differentiation of some honey types according to the botanical origin. Thus, a holistic treatment of the results was performed using partial least square discriminant analysis (PLS-DA) for classification purposes using FC, TFC, and FRAP results as data. Honeydew and blossom honey were satisfactorily discriminated (error 5%). In addition, blossom honeys can be perfectly classified according to their botanical origin based on two-class PLS-DA classification models.

RESUMO

Although current evidence supports the use of dry needling for improving some clinical outcomes in people with neck pain, no previous research explored the effects of dry needling on the central processing of pain and autonomic nervous system in this population. Therefore, this clinical trial aimed to compare the effects of real and sham dry needling on autonomic nervous system function, pain processing as well as clinical and psychological variables in patients with chronic nonspecific neck pain. A double-blinded randomized clinical trial including 60 patients with neck pain was conducted. Patients were randomized to the real needling (n = 30) or sham needling (n = 30) group. Skin conductance (SC), pressure pain thresholds (PPTs), temporal summation (TS), conditioned pain modulation (CPM) as well as pain intensity, related-disability, catastrophism, and kinesiophobia levels were assessed by an assessor blinded to the allocation intervention. The results did not find significant group * time interactions for most outcomes, except for the global percentage of change of SC values (mean: F = 35.90, p < 0.001, ηp2 = 0.459; minimum: F = 33.99, p = 0.839, ηp2 = 0.371; maximum: F = 24.71, p < 0.001, ηp2 = 0.037) and PPTs at C5-C6 joint in the same side of needling (F = 9.982; p = 0.003; = 0.147), in favor of the dry needling group. Although the proportion of subjects experiencing moderate to large self-perceived improvement after the intervention was significantly higher (X2 = 8.297; p = 0.004) within the dry needling group (n = 18, 60%) than in the sham needling group (n = 7, 23.3%), both groups experienced similar improvements in clinical and psychological variables. Our results suggested that dry needling applied to patients with chronic nonspecific neck pain produced an immediate decrease in mechanical hyperalgesia at local sites and produced an increase in skin conductance as compared with sham needling. No changes in central pain processing were observed. A single session of sham or real dry needling was similarly effective for decreasing related disability, pain intensity, catastrophism, and kinesiophobia levels. Further studies are needed to better understand the clinical implications of autonomic nervous system activation on central sensitization and pain processing in the long-term after the application of dry needling.

RESUMO

Background: hearing disorders in the premature newborns impact on their development and language and therefore, on their quality of life. Several risk factors have been associated to these conditions, but little is known about socioeconomic, nutrition factors and food security. Objective: to analyze the association between food security and prenatal risk factors in newborns with hearing disorders. Material and methods: study of 35 cases and 105 controls in premature newborns from 30 to 37 weeks of gestation (WG) in a public hospital. The working tool was a questionnaire to collect data about the maternal medical record and the anthropometry of the newborn, as well as the risk factors for the auditory function, sociodemographic aspects, and food security with its respective classification and food habits. Results: the principal perinatal risk factor associated to hearing impairment was the use of gentamycin (ototoxic drug) in 18.1% of the total (OR: 5.61 [1.29-24.50]). Severe food insecurity was associated with auditory disfunctions in 27.2% of cases and in 2.8% of controls (OR: 12.75 [2.89-56.16]). There were differences between the groups regarding the education level (cases: 50% of the mothers finished or interrupted primary education level vs controls with 19%; Ji2 = 0.008). The anthropomorphic variables showed differences in weight, length and cephalic perimeter for the newborns (p < 0.000). Conclusion: severe food insecurity, exposure to gentamycin and low education level of the mother had a significant association with auditory impairments in preterm children. For these newborns, variables like weight, length and cephalic perimeter at the moment of birth were lower than in controls. These initial findings point to the important role that environmental risks, like food insecurity, have in auditory impairments in addition to those previously described


Introducción: las alteraciones auditivas en el recién nacido prematuro impactan en su desarrollo y lenguaje y por ende a la calidad de vida. Se conocen varios factores de riesgo asociados a estas alteraciones, pero poco sobre los aspectos socioeconómicos, nutricionales y de inseguridad alimentaria. Objetivo: analizar la asociación con la inseguridad alimentaria y los factores de riesgo prenatales en prematuros con problemas de audición. Material y métodos: estudio de 35 casos y 105 controles, en prematuros de 30 a 37 SDG de un hospital público, realizado a través de una encuesta donde se recopilaron datos del expediente materno y del recién nacido (antropometría), así como factores de riesgo para alteración auditiva, aspectos sociodemográficos, seguridad alimentaria con sus respectivas clasificaciones y tipo de alimentación. Resultados: el principal factor de riego perinatal asociado a las alteraciones auditivas fue la administración de gentamicina (antibiótico ototóxico) en 18,1% de los casos (OR: 5,61 [IC = 1,29-24,50]). La inseguridad alimentaria severa se asoció con las alteraciones auditivas, en 27,2% de casos y en 2,8% de controles (OR: 12,75 [IC = 2,89-56,16]). Además, se encontraron diferencias entre los grupos para el nivel de escolaridad (casos: 50% de las madres tuvieron primaria terminada o incompleta vs. controles con 19%; Ji2 = 0,008) y Las variables antropométricas presentaron diferencias en peso, longitud y perímetro cefálico (p < 0,000). Conclusión: la inseguridad alimentaria severa, exposición a gentamicina, el nivel de escolaridad de la madre, tuvieron una asociación significativa con las alteraciones auditivas en el prematuro. Variables como el peso, longitud y perímetro cefálico al nacimiento presentaron valores inferiores en el grupo casos. Estos primeros hallazgos, reflejan riesgos ambientales como la inseguridad alimentaria en las alteraciones auditivas además de las ya conocidas

RESUMO

A study of the effect of the thin layer of free water in corn kernels on the emissivity and interference in the mid infrared range was performed. The emissivity was measured through thermal infrared images by direct method for 8 days, allowing observance that the thickness of free water modifies the quantity of emitted energy and emissivity; however, in the first days when the layer of free water is not optically thick the interference caused by the thin film of superficial water averts a correct measurement of the emissivity. This interference effect was studied and characterized, finding that the number of oscillations in the energy of the grain, observed and counted in a very small area, can be used to compute the thickness of the free water layer contained between the endosperm and the pericarp of the grain.

RESUMO

The presence and role of functional inositol 1,4,5-trisphosphate (IP(3)) receptors (IP(3)Rs) in adult skeletal muscle are controversial. The current consensus is that, in adult striated muscle, the relative amount of IP(3)Rs is too low and the kinetics of Ca(2+) release from IP(3)R is too slow compared with ryanodine receptors to contribute to the Ca(2+) transient during excitation-contraction coupling. However, it has been suggested that IP(3)-dependent Ca(2+) release may be involved in signaling cascades leading to regulation of muscle gene expression. We have reinvestigated IP(3)-dependent Ca(2+) release in isolated flexor digitorum brevis (FDB) muscle fibers from adult mice. Although Ca(2+) transients were readily induced in cultured C2C12 muscle cells by (a) UTP stimulation, (b) direct injection of IP(3), or (c) photolysis of membrane-permeant caged IP(3), no statistically significant change in calcium signal was detected in adult FDB fibers. We conclude that the IP(3)-IP(3)R system does not appear to affect global calcium levels in adult mouse skeletal muscle.

RESUMO

INTRODUCCIÓN. La artritis idiopática juvenil (AIJ) es una enfermedad del colágeno caracterizada por sinovitis crónica y síntomas extraarticulares, de inicio antes de los 16 años de edad. El interferón gamma (INFγ) mostró eficacia en un ensayo anterior con pacientes resistentes o intolerantes a las otras terapias disponibles, por lo que se decidió evaluar su eficacia y seguridad como medicamento modificador de la evolución de esta enfermedad. MÉTODOS. Se realizó un ensayo clínico abierto, no controlado, en el que se administró INFγ por vía intramuscular en dosis de 50 000 UI/kg (hasta 1 x 10(6) UI) durante 2 años. En el ensayo se incluyeron 20 pacientes con AIJ: 5 tenían la forma pauciarticular; 9, la poliarticular y 6, la sistémica. RESULTADOS. Al final del tratamiento, 13 pacientes (65 por ciento) se evaluaron como respondedores. El número de articulaciones afectadas, los síntomas sistémicos y los valores de eritrosedimentación y del cuestionario de calidad se redujeron significativamente. Igualmente disminuyó el número de pacientes que continuó consumiendo esteroides, así como la dosis de éstos. El tratamiento fue bien tolerado, excepto en 2 pacientes. CONCLUSIONES. El INFγ disminuye la expresión de la quimiocina CCR-4 en los niños, pero no en los adultos con la enfermedad. Es posible concluir que esta citocina puede ser una alternativa terapéutica eficaz en pacientes con AIJ; para confirmarlo se necesitan estudios controlados más extensos


INTRODUCTION: The juvenile idiopathic arthritis (JIA) is a collagen entity characterized by chronic synovitis and extra-articulation symptoms appearing before the 16 years old. Gamma Interferon (gamma-INF) showed its effectiveness in a prior trial with resistant and intolerant patients to other available gamma-INF therapies, thus authors assessed its effectiveness and safety as a modifier drug of the course of this entity. METHODS: An open clinical, no-controlled trial was carried out administering gammaINF by intramuscular route in doses of 50 000 IU/kg (up to 1 x 10(6) IU) during two years. Trial included 20 patients with JIA: five had the pauciarticular type; nine had the polyarticular one and six had the systemic one. RESULTS: At treatment termination, 13 patients (65 percent) were assessed as respondents. Figure of involved joints, the systemic symptoms and the erythrosedimentation values, and the quality questionnaire significantly decreased, as well as the figure of patients to continue consuming steroids and its dosage. Treatment was well tolerated, except 2 patients. CONCLUSIONS: Gamma-INF decrease the expression of CCR-4 chemokine in children, but not in adults ones presenting this entity. We conclude that this cytokine may be an efficient therapeutical alternative in patients with JIA; for its confirmation it is necessary more extent controlled studies

RESUMO

Realizamos un estudio descriptivo prospectivo con una muestra de 16 pacientes pertenecientes a nuestro Servicio, portadores de algunas de las entidades del tejido conectivo, que presentaron uveítis en algún momento de la evolución de su enfermedad. Encontramos igual número de casos para ambos sexos y el 50 por ciento era menor de 5 años. La mayoría tenía diagnóstico de Artritis Idiopática Juvenil. Las manifestaciones oftalmológicas más frecuentes fueron el enrojecimiento ocular y la fotofobia. Los hallazgos más relevantes en la lámpara de hendidura fueron la presencia de pigmentos y las sinequias. Todos los casos recibieron tratamiento local, asociado o no a tratamiento sistémico (esteroide y/o inmunosupresor). La evolución fue satisfactoria en la mayoría de los pacientes(AU)

RESUMO

Se realizó la manometría a nueve pacientes con edades comprendidas entre 8 y 63 años, cuatro niños y cinco adultos, con sistema abierto de perfusión contínua, en ayunas. Se analizó el comportamiento motor esofágico en cada caso y se determinaron la hernia hiatal asociada, el tono de la zona de elevada presión y su respuesta refleja, las características de la onda primaria, la función motora del esfinter esofágico superior y la presión basal del esófago. Aquéllos que padecían de esclerosis sistémica progresiva presentaron una frecuencia elevada de alteraciones de la motilidad esofágica y de la presión del esfínter esofágico inferior. Las alteraciones funcionales en nuestros casos se corresponden con los síntomas clínicos de disfagia, regurgitaciones y vómitos. La manometría esofágica realiza un importante aporte al estudio integral del paciente con colagenopatía por lo que se recomienda su utilización en estos casos
