Response Burden – Review and Conceptual Framework
Authors: Yan Ting , Williams Douglas
Published: December 2022

Concerns about the burden that surveys place on respondents have a long history in the survey field. This article reviews existing conceptualizations and measurements of response burden in the survey literature. Instead of conceptualizing response burden as a one-time overall outcome, we expand the conceptual framework of response burden by positing response burden as reflecting a continuous evaluation of the requirements imposed on respondents throughout the survey process. We specifically distinguish response burden at three time points: initial burden at the time of the survey request, cumulative burden that respondents experience after starting the interview, and continuous burden for those asked to participate in a later round of interviews in a longitudinal setting. At each time point, survey and question features affect response burden. In addition, respondent characteristics can affect response burden directly, or they can moderate or mediate the relationship between survey and question characteristics and the end perception of burden. Our conceptual framework reflects the dynamic and complex interactive nature of response burden at different time points over the course of a survey. We show how this framework can be used to explain conflicting empirical findings and guide methodological research.
Analyzing the Association of Objective Burden Measures to Perceived Burden with Regression Trees
Authors: Yang Daniel K. , Toth Daniell S.
Published: December 2022

Higher levels of perceived burden by respondents can lead to ambiguous responses to a questionnaire, item nonresponse, or refusals to continue participation in the survey which can introduce bias and downgrade the quality of the data. Therefore, it is important to understand what might influence the perception of burden in respondents. In this article, we demonstrate, using U.S. Consumer Expenditure Survey data, how regression tree models can be used to analyze the associations between perceived burden and objective burden measures conditioning on household demographics and other explanatory variables. The structure of the tree models allows these associations to easily be explored.

Our analysis shows a relationship between perceived burden and some of the objective measures after conditioning on different demographic and household variables and that these relationships are quite affected by different respondent characteristics and the mode of the survey. Since the tree models were constructed using an algorithm that accounts for the sample design, inferences from the analysis can be made about the population. Therefore, any insights could be used to help guide future decisions about survey design and data collection to help reduce respondent burden.

Objectives. Septic arthritis is a medical emergency with a mortality rate of approximately 10%, the knee being the most commonly affected joint (about 50% of cases). The systemic inflammatory response caused by septic arthritis may be affected by the severity of the infection or the success of surgical joint debridement. Materials and Methods. This article was a retrospective study on patients admitted to our hospital (between 2013 and 2020) with septic arthritis of the knee. Patients were diagnosed based on history, examination, blood test results, and knee aspirate fluid. The patient's response to antibiotic therapy was monitored in the outpatient setting using serological markers. Results. Of the 48 patients included in the study, 26 were male, and 22 were female. Based on the ROC analysis, the optimal cutoff value of preoperative NLR was 8.33. The AUC was 0.782 for postoperative NLR level (95% CI,0,626–0.938; p:0.009) and 0.922 for postoperative CAR level (95% CI,0.844–0.999; p <0.001). Postoperative NLR and CAR cutoff values are 15.4 and 115, respectively. Conclusions. Preoperative NLR elevation in septic arthritis may be associated with recurrent surgical debridement postoperatively. In addition, postoperative NLR and CAR values can predict debridement rates in patients after septic arthritis surgery.

Background. This is a clinicopathological study comparing lymph node involvement in breast carcinomas before and during the COVID-19 period. During the pandemic, access to healthcare was limited, which led to a delay in the diagnosis and treatment of malignant tumors, which often presented in advanced stages, with lymph node metastases. Methods. A retrospective study was performed on 40 patients with carcinomas treated by surgical excision of the tumor combined with lymph node resection. Histopathological examination of lymph nodes was performed to detect malignant metastases, and the mean lymph node positivity rate was calculated. Odds ratio was used to measure the association between pre covid era and covid era (p value < 0.05 being considered statistically significant). Results. Lymph node metastasis was observed in 10 patients in 2019 (50%) and in 16 patients in 2021 (80%). The average node positivity rate was significantly higher in 2021 (39.4%) than in 2019 (21.1%). Conclusion. During the Covid-19 pandemic, there was a considerable delay in presenting patients for symptoms of malignancy. This led to a delay in the diagnosis of malignancies, which were treated in advanced stages, frequently with metastases in the regional lymph nodes. Patient awareness should be improved to ensure early presentation and reporting of symptoms. Surgeons must be more vigilant and fully explore the dissection field to ensure that all involved lymph nodes are resected, thus avoiding recurrence and improving the patient's overall prognosis.

Als Folge der nationalsozialistischen Verfolgung flohen zahlreiche jüdische Historiker aus Deutschland und Österreich in die USA. Nach 1945 setzten sie sich für die wissenschaftliche Aufarbeitung des Nationalsozialismus und des Holocaust ein. In den USA avancierten sie rasch zu Pionieren für die deutsche Geschichte des 19. und 20. Jahrhunderts. Obwohl sich die Wissenschaftler um einen Austausch mit in Deutschland verbliebenen Historikern bemühten, blieben ihre Bücher in ihrem Herkunftsland teilweise über Jahrzehnte unbeachtet. Die Gründe für die Missachtung waren vielfältig: Umstritten war vor allem, wer deutsche Geschichte schreiben darf, wie deutsche Geschichte geschrieben werden soll, insbesondere ob und wie der Holocaust zu erforschen sei. Erst durch Generationswechsel sowie ein gestiegenes öffentliches Interesse intensivierte sich der Austausch zwischen den in Deutschland verbliebenen und den emigrierten Historikern. Letztere trugen wesentlich zu der wissenschaftlichen Erforschung des Nationalsozialismus und des Holocaust bei. Sie zielten auf eine lückenlose Aufklärung der deutschen Vergangenheit, um das Demokratiebewusstsein in Gegenwart und Zukunft zu stärken.

Published: December 2022

Benchtop nuclear magnetic resonance (NMR) spectroscopy has enabled the monitoring and optimization of chemical transformations while simultaneously providing kinetic, mechanistic, and structural insight into reaction pathways with quantitative precision. Moreover, benchtop NMR proton lock capabilities further allow for rapid and convenient monitoring of various organic reactions in real-time, as the use of deuterated solvents is not required. The complementary role of 19F NMR-based kinetic monitoring in the fluorination of bioactive compounds serves many benefits in the drug discovery process, since fluorinated motifs additionally improve drug pharmacology. In this study, 19F NMR spectroscopy was utilized to monitor the synthesis of novel trifluorinated analogs of monastrol, a small molecule dihydropyrimidine kinesin-Eg5 inhibitor, and to probe the mechanism of the Biginelli cyclocondensation, a multicomponent reaction used to synthesize dihydropyrimidine and tetrahydropyrimidines through a Bronsted- or Lewis-acid catalyzed cyclocondensation between ethyl acetoacetate, thiourea, and an aryl aldehyde. In the present study, a trifluorinated ketoester serves a dual purpose as being the source of the trifluoromethyl group in our fluorinated dihydropyrimidines and as a spectroscopic handle for real time reaction monitoring and tracking of reactive intermediates by 19F NMR. Further, upon extending this workflow to a diverse array 3- and 4-substituted aryl aldehydes, we were able to derive Hammett linear free energy relationships (LFER) to determine stereoelectronic effects of para- and meta- substituted aryl aldehydes to corresponding reaction rates and mechanistic routes. In addition, we used density functional theory (DFT) calculations to corroborate our experimental results through the thermodynamic values of key intermediates in each mechanism. Finally, these studies cumulate in the synthesis of a novel trifluorinated analog of monastrol and its subsequent biological evaluation in vitro. More broadly, we show an application of benchtop 19F NMR spectroscopy as an analytical tool in the real-time investigation of a mechanistically and chemically complex multicomponent reaction mixture.
Bayesian optimisation for additive screening and yield improvements in chemical reactions – beyond one-hot encodings
Authors: Ranković Bojana , Griffiths Ryan-Rhys , Moss Henry B. , Schwaller Philippe
Published: December 2022

Reaction additives play a significant role in controlling the reactivity and outcome of chemical reactions. For example, a recent high-throughput additive screening identified a phthalimide ligand additive Ni-catalysed photoredox decarboxylative arylations. This discovery enabled a 4-fold yield improvement by stabilising oxidative addition complexes and breaking up deactivated catalyst aggregates. However, such large-scale screenings are currently inaccessible to most research groups. This work demonstrates how these discoveries can be made under much lower experimental budgets using Bayesian optimisation. We consider a unique reaction screening setting with 720 additives which forces us to go beyond simple one-hot encoding of the reaction components. We investigate a range of molecular representations and demonstrate convincing improvements over baselines. Our approach is not limited to Ni-catalysed reactions but can be generally applied to, for example, achieving yield improvements in diverse cross-coupling reactions or unlocking access to new chemical spaces of interest to the chemical and pharmaceutical industries.

FARMERS’ PERCEPTION OF CLIMATE CHANGE AND PARTHENIUM WEED DISTRIBUTION IN DISTRICT SWABI, KHYBER PAKHTUNKHWA
Authors: Khan Haroon
Published: December 2022

Climate change is the principal concern of present day agriculturists, environmental scientists and ecologists. Climate change and its negative impacts is still not fully understood and the concept is still criticized for its validity. The present research work consists of two phases. The first phase analyzed the farmersâ€™ perception of climate change and its likely impact on weeds distribution by conducting a formal survey and in the 2nd phase a laboratory experiment was conducted on Parthenium weed selected from study area in Weed Science Department, The University of Agriculture, Peshawar to correlate the findings of both phasesin July-September, 2016. The field survey was carried out in Jan-May, 2016 in Swabi district, Khyber Pakhtunkhwa- Pakistan. 100 farmers from the study area were randomly interviewed through a questionnaire comprised of all relevant parameters to assess their perception of climate change and its consequences.  Most of the farmers (61%) believed in climate change and its negative consequences and complained of lower efficiency of their farming in the changed scenario. They had noticed climatic variations, for the last 20 years, in the form of  summers extension, winters flexion, unexpected and changed pattern of rainfalls (58% responses for increase) with summer rainfalls earlier (68%) and winter rainfalls later (35%), severe and destructive floods (75%), storms or strong winds (77%), hailstorms (67%) and higher  insects/ pests attack causing harm to crops (68%), livestock/ animal (64%) and humans. The changed scenario also posed difficulties to farmers in managing agricultural activities like abundance of weed species (62% farmers strongly agreed) especially the invasive ones e.g. Parthenium hysterophorus, Silybam marianum and Rumex crispus etc. They noticed increase in weed species (78%), frequency (69%) and interaction (78%) among native and invasive weeds. These weeds had aggressive (75%) and uncontrollable growth (68%), out competed the crops (82%), and survived longer (55%). From the field study Parthenium weed was concluded (82%) as the most responsive invasive weed to climate change and was selected for lab study. The experiment was laid out in Completely Randomized Design (CRD) with 4 replications. The treatments comprised of 5 different temperature regimes of 15, 20, 25, 30 and 35 Â°C in controlled situation in an incubator. The analysis illustrated that high germination % (34.50%) of Parthenium weed seeds occurred at higher temperature (30Â°C) than optimum (25Â°C) which was 29.25%, following the same pattern for the growth which remained more (19.75) and (17.45) at higher temperatures of (30Â°C) and (35Â°C) respectively than optimum (16.95). The conclusion of lab experiment was that the rise in temperature is favoring the growth of Parthenium weed. This weed is reported in the surveyed area to be highly aggressive and competitive for the indigenous flora expanding its domain in the area.

En esta investigación se realizó una comparación entre las actividades dedicadas al ocio durante la pandemia y post pandemia para diagnosticar las preferencias de los consumidores de ocio desde la teoría de Dumazedier, con cuatro rubros que generalizan los tipos de ocio. Los resultados describen el comportamiento de los consumidores y su gestión del tiempo libre. Los factores destacados durante la post pandemia fueron actividades de ocio físico y social, principalmente, las actividades físicas; respecto al uso de tiempo estético, el cuidado personal y dormir tuvieron preferencia con mayor énfasis en la post pandemia; sólo de dos a tres personas realizan manualidades y, por último, respecto al ocio intelectual, se exhibe la preferencia por escuchar música y por la lectura y, en menor preferencia, refieren visitas culturales y artes. Un factor importante a destacar fue el empleo, ya que durante la pandemia y post pandemia no se generó alguna alteración teniendo como resultado que se ejerce de igual modo durante estos dos periodos. Finalmente, una circunstancia negativa para ejercer el ocio fue la falta de tiempo y el agotamiento físico y mental de los encuestados.

Published: December 2022

El aprendizaje de las matemáticas ha resultado, para algunos estudiantes, un impedimento para el éxito de sus metas académicas; de modo que ha trascendido y se establece como un obstáculo emocional y cognitivo. Lo que el estudiante experimenta, observa, cree, la manera en cómo percibe la enseñanza de parte del profesor, y la concepción que se tiene de esta disciplina dentro del medio donde se desarrolla (núcleo familia), afecta directamente en cómo concibe el aprendizaje. El presente trabajo tiene la finalidad de analizar, basado en la concepción de ciencia, teoría del cognitivismo, la dimensión afectiva y su relación con la enseñanza aprendizaje de la matemática durante el confinamiento por COVID-19. Los principales resultados obtenidos evidencian que se debe formar en nuestros estudiantes una alfabetización matemática para que puedan desarrollar un pensamiento lógico matemático que les ayude aplicar lo aprendido en clase en su vida diaria.

Hoy en día, el diseño y planeación de los trazados viales en las urbes modernas representa un gran desafío. Además, el uso masivo del transporte público y la actual complejidad de las distintas rutas que operan en las ciudades ha ocasionado que los ciudadanos requieran de ayuda al momento de planificar una ruta. Esta problemática es atendida por diversos sistemas de software que permiten que los ciudadanos puedan alcanzar un destino utilizando auto particular, como es el caso de Waze o Google Maps. Si bien estos sistemas son de gran ayuda para los usuarios finales, tienen el inconveniente de ser sistemas cerrados propiedad de una empresa. Esto ocasiona que no sea posible reutilizar estos recursos por desarrolladores que deseen crear aplicaciones para movilidad. Actualmente, muchas agencias de transporte utilizan los datos GTFS (General Transit Feed Specification) como formato estándar para publicar sus datos. En este artículo se presenta un planificador de viajes, el cual utiliza el formato estándar GTFS. Nosotros presentamos este planificador utilizando el caso de estudio de la Ciudad de México.

Creamos múltiples sociedades buscando un mejor futuro. Tomamos lo que nos gusta de algunas y lo usamos en otras. Tomamos lo que apreciamos y desechamos los que nos incomoda. Aceptamos lo que es similar a nosotros, e incluso mudamos nuestras sociedades hacia estar integradas con personas de pensamiento similar. Pero jamás idéntico porque competimos para ver quien tiene la razón en un pensamiento en común. Cuando las diferencias entre las personas de una sociedad surgen, el equilibrio como sensación de paz, desaparece y comenzamos a generar segregaciones, queriendo desarrollar una nueva sociedad. Nuestras utopías fallan. Distopia tras distopia, aquí permanecemos. Intentando organizarnos y llegar a un acuerdo común.

En tiempos de Pandemia, el teletrabajo se ha hecho habitual para hacer las labores que normalmente se desarrollaban en las empresas, organizaciones o lugares específicos, puesto que una gran parte de la fuerza laboral debió quedarse en sus hogares y trabajar a distancia. Para muchos trabajadores, la introducción del teletrabajo representó una forma de continuar procurar la productividad en determinadas áreas de trabajo. Esto significó, para el recurso humano, la ejecución de las tareas laborales desde el hogar, es decir, empleados y empleadas que anteriormente ejercían su actividad en las instalaciones de la empresa o institución, se han enfrentado a una especie de migración laboral, donde el trabajo debe realizarse utilizando las tecnologías de la información (como una computadora con internet, teléfonos, cámaras web). Algunas de las consecuencias de dichos cambios son la sobrecarga de responsabilidades, que puede asociarse a la afectación del ritmo biológicos, generación de estrés, ansiedad, irritabilidad, estados depresivos, temor y aburrimiento, sensación de aislamiento, ambigüedad o conflicto de rol; y alteraciones mentales. Del mismo modo, otros riesgos potenciales que se acentúa en esta situación sanitaria son el sedentarismo, la obesidad, hábitos de alimentación, y el consumo de tabaco, que son factores de riesgo que modifican el perfil antropométrico (peso, talla y circunferencia de cintura), bioquímico (colesterol total, HDL, LDL y glucosa), clínico (tensión arterial y frecuencia cardiaca), y son aspectos importantes a considerar para el desarrollo de enfermedades cardiovasculares (ECV), que son las que afectan tanto al sistema circulatorio, como al corazón.

Una vía poco utilizada para evaluar la práctica docente a través de la opinión de los universitarios es el análisis de redes complejas, este tipo de análisis permite observar interrelaciones múltiples en un modelo. El objetivo de la presente investigación fue comparar las opiniones abiertas de universitarios sobre la práctica docente respecto a dos planes de estudio (en derogación [PD] y en implementación [PI]). Con un muestreo no-probabilístico participaron 135 estudiantes universitarios hombres y mujeres adscritos a dos planes de estudio, quienes posterior a firmar un consentimiento informado, contestaron preguntas abiertas sobre el desempeño docente. El modelo del PD tiene una estructura más compleja en términos de relaciones, comparado con el PI. Se concluye que, en ambos planes se valora el dominio de los conocimientos, pero en el PD interactúa con la falta de claridad expositiva, falta de planeación de las actividades con atributos personales negativos como la intolerancia y poca accesibilidad y en PI se valora el dominio del conocimiento con atributos positivos como la amabilidad

Published: December 2022

El trabajo presenta un proceso de intervención de clínica psicoanalítica grupal denominado Grupo de Acontecimiento con tres mujeres que testimoniaron su experiencia durante la pandemia. El dispositivo se realizó de modo digital. Se caracterizan los soportes teóricos de esta modalidad de praxis clínica y se describen puntualmente las narrativas en sus tres diversos momentos y versiones. Cada una de estas fases discursivas es motivo de reflexión analítica para advertir sus alcances de significación histórica, subjetiva e intersubjetiva. Este modo de intervención se singulariza por intentar procesar a través de escritura, verbalización y escucha situaciones de calibre traumático.

A dos años del inicio de la pandemia de COVID -19 científicos de todo el mundo, han avanzado de manera acelerada en el desarrollo de vacunas seguras y eficaces que ayudarán a reducir las enfermedades, hospitalizaciones y muertes asociadas a la COVID- 19.  En México, impactó gravemente a la población con morbilidades. En el caso de los pacientes pediátricos, la incidencia es mucho menor en comparación con los adultos, sin embargo, en algunos casos, las complicaciones de la enfermedad también se presentan en ellos, registrando decesos en este grupo de edad en nuestro país.  La decisión de vacunar universalmente o no a los niños frente a COVID-19 fue compleja, y se tomaron en cuenta factores científicos, éticos, políticos, epidemiológicos y económicos. El objetivo del presente material de apoyo didáctico es brindar información con un lenguaje sencillo y claro, sobre los resultados científicos del proceso de vacunación en la población pediátrica, que permita despejar dudas al respecto y conocer los beneficios de esta.
Incidencia de las redes sociales virtuales en el desarrollo de la ciudadanía global en preparatorianos hidalguenses

El objetivo del artículo que se presenta es mostrar la importancia de las redes sociales virtuales y el uso, sobre todo social,  que hacen las y los jóvenes preparatorianos hidalguenses en la construcción de una ciudadanía global. Para dar cuenta de ello se realizó una investigación, cuya metodología fue mixta, es decir, cuantitativa a través de una encuesta, y cualitativa mediante 3 grupos focales. El cuestionario atendió a los siguientes tópicos: conectividad, uso de redes sociales, actividades en ellas, reacciones y perspectivas. Los grupos focales atendieron a tres bloques: redes sociales, política y ciudadanía, ciudadanía y ciudadanía global. Los principales hallazgos encontrados fueron que el uso de las redes sociales entre los jóvenes está muy extendido, sobre todo en páginas de entretenimiento, reaccionando y difundiendo aproximadamente la mitad de los encuestados a temas de derechos humanos, y menor medida hacen un uso de ellas para la discusión y el activismo social, a pesar de que mayoritariamente consideran que generan dinámicas de movilización social, solidaridad global, pensamiento crítico y que pueden ayudar a generar una sociedad más democrática. Estos datos extraídos del análisis de datos de la encuesta se complementan con la información obtenida en la fase cualitativa del estudio. De ellas se destaca que los participantes significaron a las redes sociales principalmente como: refugio, universo virtual, centro de convivencia, caos ordenado; reconocen que su uso ha cambiado la forma en que las personas se relacionan entre sí y se comunican, así como su autopercepción y la percepción que tienen de los demás y de la sociedad; mantienen una posición ambivalente respecto al tipo de ciudadanía al que se adscriben, conteniendo elementos de la liberal –vínculo jurídico-, republicana –participación ciudadana- y comunitaria –pertenencia a una comunidad-, así como de una más cosmopolita que identifican con las posibilidades que ofrecen las redes sociales. Las conclusiones principales fueron que los preparatorianos hidalguenses utilizan a menudo las redes sociales, son importantes en su vida cotidiana, conocen sus alcances y posibilidades de información, y difusión temas sociales y de movilización, también reconocen su capacidad democratizadora y de conformación de una ciudadanía global, aunque son pocos los que señalan participar activamente en ella.
Gestión del territorio y gobernanza: análisis de la institucionalización del ordenamiento territorial sostenible en 25 municipios del estado de Hidalgo
Authors: Vera Flores Marco Antonio , Bass Zavala Sonia
Published: December 2022

Las políticas de desarrollo territorial cobran relevancia en la medida que se implementan acciones que promuevan el desarrollo de la población en el territorio, pero preservando el equilibrio con los recursos disponibles, es decir, asegurando un ordenamiento territorial sostenible. Las directrices y disposiciones se erigen en la normatividad, pero esto no asegura que los gobiernos, específicamente los locales, implementen las políticas y acciones necesarias para lograr tales fines. Esto evidencia una frágil institucionalización de la gestión del territorio por las autoridades municipales, con brechas para armonizar su normatividad, repercutiendo en el desconocimiento de las responsabilidades del servidor público encargado de las áreas, exclusión de la participación ciudadana en la gestión territorial y, en general, pocos avances en la planeación sustentable de los asentamientos. El objetivo de este trabajo es analizar los instrumentos que permiten la gestión del territorio a nivel municipal y el grado de institucionalización que estos tienen entre los funcionarios municipales encargados de implementar o planear las políticas de gestión urbana sostenible. Se realizó un análisis documental y la implementación de un cuestionario dirigido a funcionarios públicos municipales.
Cemal Süreya ve Kadın Korkusu
Authors: YEŞİLYURT Türkân
Published: December 2022

Kadın, Cemal Süreya’nın şiirlerindeki ana temalardan biridir. Bu yazıda şairin Güz Bitiği adlı kitabına kadarki şiirlerinde görünürde kadına aşkla yaklaştığı, gerçekte erkeğe olumlu nitelikler (üstün güç, sevinç) yüklerken kadına olumsuz nitelikler (kötü güç, tehlike) yüklediği saptanmıştır. Bunun temelinde ise “kadın korkusu”nun olduğu ortaya konmuştur. Kadın korkusu ilginç bir biçimde “mizojini” olarak kendini gösterir. Cemal Süreya’nın şair duyarlığı ile “kadın korkusu”nu aşma yolu şiir olur. Yazıda “mizojini” ve “kadın korkusu” ile ilgili olarak Jack Holland ve Maurice Daumas’nın görüşlerinden yararlanılmıştır. Şiirlerde üstün güç, erkeğe ait, kötü güç kadına ait bir nitelik olarak ortaya çıkar. Ateş, dişi maddeye şekil veren erkek ilkeyi; kirli ve karanlık su ise kadını işaret eder. Kadın erkeğin cinsel arzusunu uyandırdığı için cezbedici olduğu kadar tehlikeli bulunur. Kadın tehlikeyle ilişkilendirilirken sevinç erkekle ilgilidir. Kadına basmakalıp düşüncelerle yaklaşan ve cinsel nesne olarak gören erkek bakış, kadında insandan önce bedeni görür. Şair, birçok şiirinde kadın bedenini haz nesnesine dönüştürür. Bu şiirler mizojininin izlerini taşır. Mizojinide erkeklerde cinsel arzu uyandırdıkları için bundan erkekler değil -suçlu olmadıkları halde- ister iyi ister kötü olsunlar kadınlar sorumlu tutulur. Kadın düşmanlığının temelinde ise kadın korkusu vardır. Mizojiniyi aşkla ve şiirle aşmaya çalışan şair, “Üvercinka” adlı şiirde portresi görülen aydın, şiiri bilen, cesur, çekici kadını hayal eder; ancak bu kadını içselleştirmesi zaman alır. Cemal Süreya, yaşamındaki incinmelerden kaynaklanan mizojinik izleri Güz Bitiği adlı şiir kitabında siler.

Procedures in life sciences research laboratories often require chemicals and plasticware that are costly, toxic or pose a risk to the environment. Therefore, sustainable alternatives would be of interest, provided that they generate suitable data quality. Coomassie blue and silver staining are the most widely used methods for detecting proteins following electrophoresis in the laboratory. However, their use presents challenges in terms of safety and waste management. In the current study, aqueous extracts were prepared from a series of common food species and evaluated as alternative stains for protein detection. Beets, blueberries, purple cabbage, raspberries and strawberries were employed to stain identical proteins separated under the same conditions in electrophoresis gels. Extracts of the first two species resulted in protein bands that were detectable through visible light transillumination, whereas extracts from all five species generated specific protein bands under ultraviolet light. The raspberry-derived extract was selected for further study based on the brightness of the fluorescent protein bands and minimal background staining. For both bovine serum albumin and lysozyme at 2.5 μg and 0.5 μg protein per band, the mean signal intensities obtained with raspberry extract staining were just below half of those obtained with Coomassie blue. Furthermore, the mean intensities using raspberry extract were equivalent to those obtained using Coomassie blue in the detection of 0.1 μg protein. Therefore, raspberry could be used to produce an effective stain for the routine laboratory analysis of proteins.
