ABSTRACT Culture plays a significant buying role in shaping different aspects of consumer behavior such as rational, impulse, and compulsive buying behavior. Impulse buying is one of the prevalent phenomena that significantly affect the sales revenue of companies. This study focuses on unveiling the interaction between cultural factors and impulse buying behavior. For this systematic literature review, 112 significant articles were examined to understand the relationship between various aspects of culture and impulse buying behavior in both online and offline contexts. Further investigation of impulse buying in cross-cultural context helps to understand and classify different theoretical perspectives to study impulse buying behavior and cultural factors. This study offers practical implications for retail professionals and e-commerce strategists to design and implement viable cross-cultural marketing campaigns. Academic researchers may also understand research gaps and contribute further to understanding cross-cultural impulse buying.

Resumo Introdução: Uma alta incidência de eventos de doença cardiovascular (DCV) e mortalidade prematura é observada em pacientes com doença renal crônica (DRC). Assim, novos biomarcadores que podem ajudar a prever o desenvolvimento de DCV nos estágios iniciais da DRC estão sendo investigados juntamente com outros fatores de risco tradicionais. Objetivo: Investigar a catepsina S como um biomarcador precoce para DCV em pacientes com DRC. Métodos: Um total de 64 pacientes com DRC foram incluídos e classificados em 2 grupos: pacientes com DRC com DCV estabelecida e pacientes com DRC com DCV não estabelecida. Todos os pacientes foram submetidos a investigações de rotina incluindo hemograma completo, glicemia aleatória, hemoglobina glicada (HbA1C), eletrólitos séricos, ureia, creatinina, proteína total, albumina total, cálcio total, fósforo, ácido úrico, vitamina D, paratormônio, perfil lipídico, teste de função hepática, medição da catepsina S sérica (Cat S), e Eco 2D do coração. Resultados: O nível de Cat S sérica esteve aumentado em pacientes com DRC com DCV (p <0,05), bem como em estágios posteriores da DRC (p <0,05). A DCV também foi mais comum em pacientes com DRC em estágio inicial. Em estágios iniciais da DRC, a Cat S e a DCV foram positivamente correlacionadas. Conclusão: Estes achados sugerem que a Cat S sérica pode ser útil como um biomarcador precoce para DCV em pacientes com DRC.

Abstract Introduction: A high incidence of cardiovascular disease (CVD) events and premature mortality is observed in patients with chronic kidney disease (CKD). Thus, new biomarkers that may help predict the development of CVD in early stages of CKD are being investigated along with other traditional risk factors. Objective: To investigate cathepsin S as an early biomarker for CVD in patients with CKD. Methods: A total of 64 patients with CKD were included and classified into 2 groups: CKD patients with established CVD and CKD patients with non-established CVD. All patients were submitted to routine investigations including complete blood count, random blood sugar, glycated hemoglobin (HbA1c), serum electrolytes, urea, creatinine, total protein, total albumin, calcium total, phosphorous, uric acid, vitamin D, parathormone, lipid profile, liver function test, measurement of serum cathepsin S (Cat S), and 2D Echo of the heart. Results: The level of serum Cat S was increased in CKD patients with CVD (p <0.05) as well as in later stages of CKD (p <0.05). CVD was also more common in patients in early stage CKD. In early stages CKD, Cat S and CVD were positively correlated. Conclusion: These findings suggest that serum Cat S might be useful as an early biomarker for CVD in CKD patients.

Abstract A fast, reproducible, and sensitive method is proposed for the kinetic determination of carbocisteine (CCys). The method depends on the inhibitory property of carbocisteine, which reduces the Hg2+ catalyzed substitution rate of cyanide from [Ru(CN)6]4- with N-R-salt (1-Nitroso-2-naphthol-3,6-disulfonic acid disodium salt) via forming a stable complex with Hg2+. Spectrophotometric measurements were carried out by recording the absorbance at 525 nm (λmax of [Ru(CN)5 Nitroso-R-Salt]3- complex) at a fixed time of 10 and 15 min under the optimized reaction conditions with [N-R-salt] = 4.5 × 10-4 M, I = 0.05 M (KNO3), Temp = 45.0 ± 0.2 o C, pH = 7.0 ± 0.03, [Hg2+] = 8.0 × 10-5 M and [Ru(CN)6 4-] = 4.25 × 10-5 M. With the proposed method, CCys can be determined quantitatively down to 3.0 × 10-6 M. This methodology can be effectively used for the rapid quantitative estimation of CCys in the pharmaceutical samples with good accuracy and reproducibility. The addition of common excipients in pharmaceuticals even up to 1000 times with [CCys] does not interfere significantly in the estimation of CCys.

Resumen Se propone un método rápido, reproducibley sensible para la determinación cinética de la carbocisteina (CCys). El método depende de la propiedad inhibitoria de la carbocisteina que reduce la tasa de sustitución catalizada por Hg2+ del cianuro de [Ru(CN)6]4- con la sal N-R (sal disódica del ácido 1-Nitroso-2-naftol-3,6-disulfónico) mediante la formación de un complejo estable con Hg2+. Las mediciones espectrofotométricas se llevaron a cabo registrando la absorbancia a 525 nm (λmax del complejo [Ru(CN)5 Sal-Nitroso-R]3-) en un tiempo fijo de 10 y 15 min en las condiciones de reacción optimizadas con [sal-NR] = 4.5 × 10-4 M, I = 0.05 M (KNO3), Temp = 45.0 ± 0.2 o C, pH = 7.0 ± 0.03, [Hg2+] = 8.0 × 10-5 M y [Ru(CN)6 4-] = 4.25 × 10-5 M. Con el método propuesto, CCys se puede determinar cuantitativamente hasta 3,0 × 10-6 M. Esta metodología se puede utilizar eficazmente para la estimación cuantitativa rápida de CCys en las muestras farmacéuticas con buena precisión y reproducibilidad. La adición de excipientes comunes en productos farmacéuticos incluso hasta 1000 veces con [CCys] no interfiere significativamente en la estimación de CCys.

Resumo Objetivos O presente estudo tem como objetivo identificar características pré-operatórias do paciente e da lesão, bem como da imagem que apontaria para uma fratura tipo IV. O presente estudo ajudará a equipe operacional a prever com mais precisão o padrão tipo IV pré-operatório, levando a um melhor aconselhamento dos cuidadores e planejamento da cirurgia, bem como a uma melhor preparação em relação à redução aberta, se tal situação surgir. Métodos Um estudo retrospectivo foi realizado, incluindo pacientes que atendiam os seguintes critérios: 1) idade < 16 anos; 2) fraturas supracondilares Gartland tipos III e IV; e 3) com registros completos. Foram coletados dados demográficos como idade, gênero, lateralidade, modo de lesão, duração hospitalar de lesão, histórico de tentativas anteriores de redução fechada, fratura aberta/fechada, estado neurovascular distal e dados radiográficos como angulação, translação, aposição óssea e cominação de fratura. Resultados A duração hospitalar de lesões e as tentativas anteriores de redução fechada foram os fatores com diferença estatisticamente significativa entre as fraturas tipo III e IV (p < 0,05). O diagnóstico de fraturas supracondilares tipo IV foi significativamente mais provável na presença de angulação em valgo de fragmento distal ≥ 17º (odds ratio [OR] = 20,22; intervalo de confiança [IC] 95% = 3,45–118,65). A angulação de flexão ≥ 10º (OR = 5,32; IC95% = 0,24–119,88) do fragmento distal previram Gartland tipo IV com sensibilidade de 41% e especificidade de 100%. Conclusão A avaliação pré-operatória de suspeitas de fraturas de Gartland IV pode ajudar o cirurgião operacional a prever tais lesões. Fatores não radiográficos, como o aumento da duração da lesão hospitalar, tentativas de redução previamente fechada e parâmetros radiográficos como valgo e angulação de flexão foram mais propensos a estarem associados a fraturas tipo IV. Nível de evidência III.

Abstract Objectives The present study aims to identify preoperative characteristics of the patient, of the injury, as well as of imaging, which would point towards a type IV fracture. The present study shall help the operating team to predict more accurately the type IV pattern preoperatively, leading to improved counselling of the caregivers, planning of surgery, as well as preparedness regarding open reduction, if such situation arises. Methods A retrospective study was conducted, including patients that met the following criteria: 1) age < 16 years old; 2) Gartland type-III and type-IV supracondylar fractures; and 3) with complete records. Demographic data like age, gender, laterality, mode of injury, hospital duration of the injury, history of previous attempts of closed reduction, open/closed fracture, distal neurovascular status, and radiographic data like angulation, translation, osseous apposition and fracture comminution were collected. Results Hospital duration of the injury and previous attempts of closed reduction were the factors that had a statistically significant difference among types III and IV fractures (p < 0.05). A diagnosis of type IV supracondylar fractures was significantly more likely in the presence of valgus angulation of the distal fragment ≥ 17º (odds ratio [OR] = 20.22; 95% confidence interval [CI] = 3.45–118.65). Flexion angulation ≥ 10º (OR = 5.32; 95% CI = 0.24–119.88) of the distal fragment predicted Gartland type IV with a sensitivity of 41% and a specificity of 100%. Conclusion The preoperative evaluation of suspected Gartland IV fractures can help the operating surgeon in predicting such injuries. Nonradiographic factors like increased hospital duration of the injury, attempts at previously closed reduction, and radiographic parameters like valgus and flexion angulation were more likely to be associated with type IV fractures. Level of evidence III.

Abstract Introduction: Reconstruction of right ventricular outflow tract during primary repair of tetralogy of Fallot often requires the placement of a transannular patch which results in pulmonary regurgitation (PR). We compared the short-term outcomes of bicuspid polytetrafluoroethylene membrane valve versus transannular pericardial patch reconstruction of the right ventricular outflow tract. Methods: Thirty consecutive patients undergoing primary repair of tetralogy of Fallot were randomly allocated to two groups - polytetrafluoroethylene valve (PTFEV) group (n=15) and transannular pericardial patch (TAP) group (n=15). The two groups had similar preoperative demographic characteristics. We compared the short-term clinical and echocardiographic outcomes between these groups. The transthoracic echocardiographic follow-up was performed at one week, one month and six months after surgery. Results: The PTFEV group had significantly lower central venous pressure in the immediate postoperative period compared to the TAP group (7.60±2.06 vs. 10.13±1.73, P=0.002). Extubation time was significantly shorter in the PTFEV group compared to the TAP group (12.93±7.55 hrs vs. 22.23±15.11 hrs, P=0.04). PR in the PTFEV group was absent in five patients at 24 hours post-surgery. At the study endpoint, PR was absent in six, trivial in one and mild in eight patients in the PTFEV group compared to TAP group, where all 15 patients had severe PR. Conclusion: The bicuspid polytetrafluoroethylene membrane valves significantly decrease the central venous pressure in the immediate postoperative period, facilitate early extubation and, thus, prevent ventilator-related comorbidities. They achieve a high degree of pulmonary competence and do not increase the right ventricular outflow tract gradient in short-term follow-up.

Abstract Objective Floating knee injuries are complex injuries and are usually caused by highvelocity trauma. These injuries are often associated with life treating injuries, which should take precedent over extremity injuries. The authors reviewed the outcomes of floating knee injuries managed in this institute from 2003 to 2015. Method A retrospective study was conducted of all patients with floating knee injuries from2003 to 2015. Twelve patients were included in the study. Data related to fracture type, associated injuries, treatmentmodalities, and complications were noted. Functional assessment was performed using themodified Karlstromand Olerud criteria after complete bony union. Result The mechanism of injury was motor vehicle accident in all patients. The mean follow up was four years. The mean age of patients was 34.75 year. The mean union time was 6.5 months in femurs and 6.7 month in tibias. The complications were knee stiffness, delayed union, and infection. According to modified Karlstrom criteria, there were three - excellent, five - good, three - fair, and one poor result. Conclusion Floating knee injuries are severe injuries and are usually associated withmultiorgan injuries. Early detection and appropriate management of associated injuries, early fixation of fractures, and postoperative rehabilitation are needed for good outcome. Complications are frequent, in the form of delayed union, knee stiffness, and infection.

Abstract The purpose of the study was to develop a xenogenic bubaline diaphragm matrix (BDM) for abdominal hernia repair. A fresh diaphragm was decellularized using aqueous sodium dodecyl sulfate (SDS) solutions (0.5-4% w/v) over a period. Acellularity was confirmed histologically and characterized by Masson’s trichrome staining, scanning electron microscopy (SEM), DNA quantification, agarose gel electrophoresis, and Fourier-transform infrared spectroscopy. The BDM was used for clinical abdominal hernia repair in six cattle. Clinical, hemato-biochemical and antioxidant parameters were evaluated to assess biocompatibility of xenogenic BDM. Histologically, the diaphragm treated with 2% SDS for 48 h showed complete acellularity and orderly arranged collagen fibers. The SEM confirmed preservation of collagen structure and integrity. The DNA content was significantly (P < 0.05) reduced in BDM (33.12 ± 5.40 ng/mg) as compared to the native diaphragm (443.96 ± 162.60 ng/mg). DNA extracts from BDM show considerable removal of DNA material, with absence of DNA band in agarose gel. The FTIR spectrum of BDM has shown all characteristic transmittance peaks of bovine skin collagen indicating preserved collagen structure. Six cattle with BDM implant recovered uneventfully and remained sound at least upto 6 months. Hemato-biochemical and antioxidant findings were unremarkable. Bubaline diaphragm matrix shows excellent repair efficiency and biocompatibility for abdominal hernia repair in cattle without complications.

Abstract: This paper presents an integrated framework to generate extractive aspect-based opinion summary from a large volume of free-form text reviews. The framework has three major components: (a) aspect identifier to determine the aspects in a given domain; (b) sentiment polarity detector for computing the sentiment polarity of opinion about an aspect; and (c) summary generator to generate opinion summary. The framework is evaluated on SemEval-2014 dataset and obtains better results than several other approaches.

ABSTRACT The Karush-Kuhn-Tucker type necessary optimality conditions are given for the nonsmooth minimax fractional programming problem with inequality and equality constraints. Subsequently, based on the idea of L-invex-infine functions defined in terms of the limiting/Mordukhovich subdifferential of locally Lipschitz functions, we obtain sufficient optimality conditions for the considered nonsmooth minimax fractional programming problem and also we provide an example to justify the existence of sufficient optimality conditions. Furthermore, we propose a parametric type dual problem and explore duality results.

Mandibular fractures are less common in children as compared to adults. The treatment plan in children has to be modified as compared to adults considering the presence of tooth buds and potential disturbances in growth. Use of acrylic splints has been one of the popular techniques in children because of its relatively easy placement and reduced risk of hindrances to growth of jaw. These splints have been traditionally been fixed with the help of cements and circummandibular wires. We describe the use of intravenous cannula stilete instead of traditional bone awl to secure the splint in place.

En comparación con los adultos, las fracturas maxilares son menos frecuentes en niños. El plan de tratamiento en niños ha de modificarse en comparación con los adultos considerando la presencia de los brotes dentales y las posibles alteraciones del crecimiento. La utilización de férulas acrílicas ha sido una de las técnicas populares en niños debido a su facilidad de colocación y a la reducción del riesgo de obstáculos en el crecimiento maxilar. Tradicionalmente estas férulas se han fijado con la ayuda de cemento y una ligadura de alambre circunmaxilar. Describimos el uso de una cánula-estilete intravenoso en lugar del instrumento tradicional usado para fijar la férula.

Biodegradation and detoxification of dyes, Malachite green, Nigrosin and Basic fuchsin have been carried out using two fungal isolates Aspergillus niger, and Phanerochaete chrysosporium, isolated from dye effluent soil. Three methods were selected for biodegradation, viz. agar overlay and liquid media methods; stationary and shaking conditions at 25 °C. Aspergillus niger recorded maximum decolorization of the dye Basic fuchsin (81.85%) followed by Nigrosin (77.47%), Malachite green (72.77%) and dye mixture (33.08%) under shaking condition. Whereas, P. chrysosporium recorded decolorization to the maximum with the Nigrosin (90.15%) followed by Basic fuchsin (89.8%), Malachite green (83.25%) and mixture (78.4%). The selected fungal strains performed better under shaking conditions compared to stationary method; moreover the inoculation of fungus also brought the pH of the dye solutions to neutral from acidic. Seed germination bioassay study exhibited that when inoculated dye solutions were used, seed showed germination while uninoculated dyes inhibited germination even after four days of observation. Similarly, microbial growth was also inhibited by uninoculated dyes. The excellent performance of A. niger and P. chrysporium in the biodegradation of textile dyes of different chemical structures suggests and reinforces the potential of these fungi for environmental decontamination.

The effect of extract of Musa paradisiaca on corrosion inhibition of mild steel in aqueous 0.5 M sulphuric acid was investigated by weight loss method, potentiodynamics polarisation technique and electrochemical impedance spectroscopy (EIS). The inhibition efficiency is found to increase with increase in concentration of the extract. Polarization measurement indicates that Musa paradisiaca acts as a mixed- type inhibitor and the inhibition efficiency decreases with rise in temperature. The inhibition is assumed to occur via adsorption of inhibitor molecules on metal surface, which obeys Langmuir adsorption isotherm. The activation energy (Ea) and other thermodynamic parameters for inhibition process were calculated. These thermodynamic parameters indicate a strong interaction between the inhibitor and the mild steel surface. SEM and AFM studies confirmed the adsorption of inhibitor molecules on mild steel surface.
