A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic.

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across different measures. Reconstrual and repurposing interventions had similar effects. Importantly, planned exploratory analyses indicated that reappraisal interventions did not reduce intentions to practice preventive health behaviours. The findings demonstrate the viability of creating scalable, low-cost interventions for use around the world

Miscibility and specific interactions in blends of poly(vinyl phenyl ketone hydrogenated) with poly(2,6-dimethyl-1,4-phenylene oxide)

The miscibility behavior of poly(vinyl phenyl ketone hydrogenated) (PVPhKH) and poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) are studied by differential scanning calorimetry, thermomechanical analysis, and FTIR spectroscopy. Two miscibility windows between 10 to 40 and 60 to 90 wt% PPO are detected. Only the blend with 50 wt% PPO is immiscible. The best fit of the Gordon-Taylor equation of the experimental glass-transition temperatures for miscible PVPhKH/PPO blends is shown. A study by FTIR spectroscopy suggests that hydrogen bonding interactions are formed between the hydroxyl groups of PVPhKH and the ether groups of PPO

Miscible blends of poly(vinyl phenyl ketone hydrogenated) and poly(styrene-co-4-vinylpyridine)

Miscibility behavior over a wide composition range was detected for polymer blends of poly(vinyl phenyl ketone hydrogenated) (PVPhKH) with poly(styrene-co-4-vinylpyridine) (PS-co-4VPy). Differential scanning calorimetry (DSC) and thermo mechanical analysis (TMA) reveal that each composition has only one glass transition temperature. The variation of the glass transition temperature with composition for PVPhKH/PS-co-4VPy miscible blends follows the Gordon-Taylor equation. FTIR analysis of this binary system indicates the existence of hydrogen bonding between pyridine ring of PS-co-4VPy and hydroxyl groups insert into PVPhKH. This specific interaction has a decisive influence in the phase behavior of PVPhKH/PS-co-4VPy blends. � 2004 Elsevier Ltd. All rights reserved

Comparative study on the nutritional and antioxidant properties of two Mexican corn (Zea mays) based meals versus processed cereals

The present study was conducted to analyze the chemical composition, total phenolics content and antioxidant capacity of two whole corn (Zea mays) based meals traditional from Mexico: "traditional pinole" and "seven grain pinole"; and compare it with information available from ready to eat cereal products based on refined corn and whole grain cereals. Proximate analyses (moisture, ash, fat, protein and fiber) were carried out according to the procedures of AOAC, sugars content was determined by HPLC method; calcium and iron were quantified using atomic absorption spectroscopy. Total phenolic compounds were determined by Folin-Ciocalteu spectrophotometric method; the antiradical capacity was determined by DPPH colorimetric method and total antioxidant capacity was determined by FRAP method. Traditional and seven grain pinole presented higher energy content and nutrient density (protein and fat) than processed cereals. Calcium content was higher in processed cereals than pinole; seven grain pinole presented the highest conentration of iron. Polyphenolic concentration was higher in both kinds of pinole compared to processed cereals; traditional pinole presented the highest antioxidant activity measured by DPPH and FRAP methods. The results provide evidence about the important nutrient and antioxidant content of traditional and seven grain pinole compared to processed cereals based on corn and other grains. It is recommended their incorporation in to regular diet as a healthy food, with a good protein level, low sugar content and good antioxidant capacity. © 2014, Archivos Latinoamericanos Nutricion.

Miscibility behavior and hydrogen bonding in blends of poly(vinyl phenyl ketone hydrogenated) and poly(2-ethyl-2-oxazoline)

The miscibility behavior of poly(2-ethyl-2-oxazoline) (PEOx)/poly(vinyl phenyl ketone hydrogenated) (PVPhKH) blends was studied for the entire range of compositions. Differential scanning calorimetry and thermomechanical analysis measurements showed that all the PEOx/PVPhKH blends studied had a single glass-transition temperature (Tg). The natural tendency of PVPhKH to self-associate through hydrogen bonding was modified by the presence of PEOx. Partial IR spectra of these blends suggested that amide groups in PEOx and hydroxyl groups in PVPhKH interacted through hydrogen bonding. This physical interaction had a positive influence on the phase behavior of PEOx/PVPhKH blends. The Kwei equation for Tg as a function of the blend composition was satisfactorily used to describe the experimental data. Pure-component pressure-volume-temperature data were also reported for both PEOx and PVPhKH. � 2004 Wiley Periodicals, Inc

Pieloplastía retroperitoneoscópica. Experiencia en el Hospital Regional de Alta Especialidad del Bajío, León, Guanajuato, México

ResumenIntroducciónLa pieloplastía laparoscópica es un procedimiento que cada día se hace más popular;alcanza éxitos que van de 89 % a 100 % y tiene menor morbilidad cuando se compara con la cirugía abierta.ObjetivoPresentar nuestra experiencia en este procedimiento con abordaje retroperitoneal. La técnica realizada fue la descrita por Rasswiler J.ResultadosSe realizaron 14 pieloplastías con abordaje retroperitoneal. Diez pacientes se sometieron a técnica de pieloplastía desmembrada, y los 4 restantes a técnica de Fenger. No se presentó algún incidente transoperatorio que haya motivado conversión a cirugía abierta. No se presentaron complicaciones transoperatorias y se tuvo un rango de sangrado de 50 a 250mL. Se tuvo un tiempo quirúrgico promedio de 182 minutos. Con un seguimiento de 31 meses, se presentó falla al tratamiento en 2 casosConclusionesEl abordaje laparoscópico se ha convertido en la técnica quirúrgica de elección para la corrección de la estenosis de la unión ureteropiélica, debido a que ofrece un éxito similar a la cirugía abierta pero con las ventajas de una menor morbilidad, tiempo de recuperación más corto y resultados estéticos favorables.AbstractBackgroundLaparoscopic pyeloplasty is an increasingly popular procedure, achieving success rates of 89 % to 100 %. It has a lower morbidity rate when compared with open surgery.AimsThe aim of this article was to present our experience with this procedure using a retroperitoneal approach. The technique was that described by J. Rasswiler.ResultsFourteen pyeloplasties with retroperitoneal approach were performed. Ten patients underwent the dismembered pyeloplasty technique and the Fenger technique was used in the remaining 4 patients. No intraoperative incident meriting conversion to open surgery occurred. There were no intraoperative complications and the range of blood loss was from 50 to 250mL. Mean surgery duration was 182 minutes. Treatment failure in 2 cases presented at the thirtyfirst month follow-up.ConclusionsThe laparoscopic approach has become the surgical technique of choice for correcting ureteropelvic junction stricture because it offers a similar success rate to that of open surgery, but with the advantages of less morbidity, a shorter recovery period, and favorable esthetic results
