Improved pore structure characterization and classification of strong diagenesis sandstones by data-mining analytics in Tazhong area, Tarim Basin
Authors: Tian Feng , Wang Xidong , Yuan Xinyi , Wang Di
Published: August 2024

The Silurian system in Tazhong area is characterized by extensive, low-abundance lithological reservoirs with strong diagenesis, resulting in significant heterogeneity. The complex pore structure in this area significantly impacts fluid control, making accurate characterization and classification of pore structures crucial for understanding reservoir properties and their influence on oil and gas distribution. Based on 314 Mercury Injection Capillary Pressure (MICP) samples in combination with core slices and thin casting slices observation, a pipeline of characterization and classification scheme by data-mining analytics of strong diagenesis sandstone pore structure types in the study zone is established, and the characteristics of different pore structures are clarified. According to the pore structure parameter abstracted by MICP data compression and variable analysis based on hierarchical clustering and principal component analysis (PCA) analysis, the variables are reasonably evaluated and screened, and the screened variables can be divided into three groups: mean pore throat radius-maximum pore throat radius-median pore throat radius-pore throat diameter mean variable group, microscopic mean coefficient variable group, and median pressure displacement pressure-relative sorting coefficient variable group. The combination of classification schemes analysed by decision tree model and linear discriminant analysis (LDA) model was determined. In the two-dimensional projection diagram of LDA model, a relatively obvious distribution of low displacement pressure, middle displacement pressure and high displacement pressure was obtained, and three distribution lines were nearly parallel. Based on the relevant information, 6 combined classification schemes suitable for final pore structure modelling were determined verified by microscopic observation. The correct characterization and classification of pore structure can be applied to the prediction of pore type, which can be used to improve the prediction of oil and gas distribution and oil and gas recovery in the future.
Validation of activity trackers to estimate energy expenditure in older adults with cardiovascular risk factors
Authors: Rieckmann Alina , Jordan Bas , Burczik Friederike , Meixner Jacqueline , Thiel Christian
Published: August 2024

Objectives

To compare different types of activity trackers recording physical activity energy expenditure (PAEE) and examine their criterion validity against indirect calorimetry (IC) as the gold standard in adults over 60 years of age with a special focus on women with cardiovascular risk.

Design

Synchronous registrations of PAEE were performed with up to four different devices to determine criterion validity against IC while participants performed a protocol of simulated activities in a laboratory setting.

Method

Thirty-four participants (25 women, 9 men) with at least a light cardiac risk performed a protocol of simulated activities in a laboratory setting (daily living activities, cycle ergometer test). PAEE was simultaneously assessed by IC, two research-grade activity trackers (ActiGraph-wGT3X-BT and Actiheart-4) and two consumer-level activity trackers (OMRON pedometer and Fitbit Charge-3). Tracker-derived PAEE was compared with PAEE calculated from IC descriptively and by Bland–Altman plots.

Results

The ActiGraph (0.7 ± 0.4 kcal/min), the Actiheart (1.1 ± 0.6 kcal/min) and the OMRON (0.8 ± 0.6 kcal/min) underestimated, while the Fitbit (3.4 ± 1.2 kcal/min) overestimated PAEE compared to IC-PAEE (2.0 ± 0.5 kcal/min). The Bland–Altman limits of agreement (LoA) against IC were +0.5/+2.2 kcal/min for the ActiGraph, -0.3/+2.1 kcal/min for the Actiheart, -3.7/+1.0 kcal/min for the Fitbit, and -0.5/+2.9 kcal/min for the OMRON. The magnitude of the deviation varied considerably depending on the activity (e.g. walking, cleaning, cycle ergometer test).

Conclusions

The research-grade activity trackers estimated PAEE with higher validity than the commercially available activity trackers. The partly very wide LoA have to be critically considered when assessing PAEE in the context of health service research, as individual Physical Activity behaviour may be under- or overestimated.
Psychometric evaluation of the Brief Resilient Coping Scale (BRCS) over the course of the pandemic in a large German general population sample
Authors: Petersen Julia , Brähler Elmar , Hettich-Damm Nora , Schepers Markus , König Jochem , Lackner Karl , Pfeiffer Norbert , Beutel Manfred E.
Published: August 2024

Background

The Brief Resilience Coping Scale (BRCS) is a brief instrument suitable for epidemiological studies. The aims of this paper were to analyze changes in BRCS depending on time, sex, age group, relationship status, as well as risk of poverty, to test the psychometric properties including test-retest reliability and measurement invariance, and to determine associations with psychosocial stress, depressiveness, anxiety, social support, as well as subjective mental and physical health. As the data from this study was collected during the pandemic, an additional sensitivity analysis was performed with pre-pandemic data.

Methods

A longitudinal study of resilience and distress in a large-sized community sample was performed at one pre-pandemic (T0) and three pandemic time points (T1-3). Resilient coping was assessed by the 4-Item short form of the BRCS, distress by the PHQ-9 and GAD-2.

Results

BRCS decreased between the first and the second and increased at the third pandemic time point. The scale had a good internal consistency. Test-retest correlation coefficients ranged from 0.527 to 0.589. Higher resilient coping was found in younger participants, participants not at-risk-of-poverty and in males. Stability was higher in those with a partner, and at-risk-of-poverty. Significant negative associations with psychosocial stress, loneliness, depressiveness, anxiety, social support, as well as subjective and physical health and SES underscored the construct validity.

Conclusion

Overall, findings underscore that resilient coping is a dynamic construct with considerable stability. The scale showed good psychometric properties including test-retest reliability over four months to two years. We found that it is not only important to describe the level of resilient coping, but also its stability.
Cardiovascular risk in US adults with nonalcoholic steatohepatitis (NASH) vs. matched non-NASH controls, National Health and Nutrition Examination Survey, 2017–2020
Authors: Woolley Jonathan J. , Fishman Jesse , Parrinello Christina M. , O’Connell Tom
Published: August 2024

Background

NASH is considered a contributor to atherosclerotic cardiovascular disease (ASCVD) risk; however, its contribution beyond traditional risk factors for CVD, particularly diabetes, is less clearly understood. This study aimed to quantify the cardiovascular-event risk associated with NASH, independent of diabetes status.

Methods

A cross-sectional analysis was conducted using the 2017–2020 NHANES pre-pandemic cycle. NASH was defined based on presence of steatosis without other causes of liver disease, and FibroScan+AST score from vibration-controlled transient elastography (VCTE). Significant fibrosis (stages F2-F4) was identified by liver stiffness measurement from VCTE. Predicted primary CV-event risk was estimated using both the Pooled Cohort Equations (PCE) and the Framingham Risk Score (FRS). NASH patients were matched with non-NASH controls on age, sex, race/ethnicity, and diabetes status. Weighted logistic regression was conducted, modeling elevated predicted CV risk (binary) as the dependent variable and indicators for NASH / fibrosis stages as independent variables.

Results

A sample of 125 NASH patients was matched with 2585 controls. NASH with significant fibrosis was associated with elevated predicted 10-year CV risk, although this association was only statistically significant in PCE analyses (odds ratio and 95% CI 2.34 [1.25, 4.36]). Analyses restricting to ages <65 years showed similar results, with associations of greater magnitude.

Conclusion

Independent of diabetes, a significant association was observed between NASH with significant liver fibrosis and predicted primary CV-event risk in US adults, particularly for those <65. These findings suggest the importance of accounting for NASH and liver-fibrosis stage in predicting CV-event risk.

Comprensión de textos: conceptos básicos y avances en la investigación actual
Authors: Sánchez Miguel Emilio , García-Rodicio Héctor
Published: August 2024

En las últimas décadas una parte significativa de la investigación en Psicología Básica y Educativa se ha dedicado a estudiar cómo procesamos el discurso y, en particular, los textos. Gracias a ello, contamos hoy día con una imagen más o menos clara de lo que pasa y de lo que queda en nuestra mente cuando leemos un discurso escrito. En las páginas que siguen trataremos de divulgar ese conocimiento acumulado. En concreto, explicaremos qué es comprender un texto, qué operaciones mentales llevamos a cabo para conseguirlo y por qué en ocasiones no comprendemos. Por fortuna para estudiosos y profesionales, la investigación en comprensión de textos no está estancada ni mucho menos: aún quedan múltiples interrogantes por despejar, los cuales animan la investigación actual. En la segunda parte del artículo hacemos un recorrido somero por las líneas más vivas actualmente y pasaremos revista a algunos de sus resultados más sobresalientes. Concretamente, hablaremos sobre el papel de lo extratextual, las nuevas situaciones de lectura, el aprendizaje de conceptos a partir de textos, la naturaleza de la representación mental del significado y el desarrollo de nuevas técnicas de investigación.
Asociacionismo y sindicalismo docente durante la transición en España (1970-1983)
Authors: Hernández Díaz José M.ª
Published: August 2024

Durante la transición política española desde la dictadura franquista a la democracia se produce un formidable movimiento de profesores a favor a un mismo tiempo de la innovación pedagógica, de una escuela democrática y pública, que no encuentra fácil comparación con otros países europeos del contexto próximo. Ello se debe a la fragilidad del asociacionismo docente y a un sindicalismo débil e incipiente entre los profesores españoles. A partir de 1983 los procesos van a cambiar rápida y profundamente.

Educación y sesgo de familia: aproximación a la vulnerabilidad laboral de las mujeres casadas en España 2005-2012
Authors: Cañada Vicinay Juan A.
Published: August 2024

El propósito de este trabajo es analizar el papel de la educación en la desigualdad laboral por razones de género, edad y estado civil en España en el período 2005.t1-2012.t4 con los datos individuales de la EPA. Los ejes de indagación son dos: 1.º) aproximación en corte transversal al sesgo de familia expresado en los perfiles laborales del ciclo de vida, la segregación ocupacional, la concentración del empleo en grupos de ocupación y el reparto de las cargas familiares entre cónyuges y 2.º) tratamiento longitudinal en panel deslizante de la interferencia de la familia en la posición de mercado de las mujeres casadas según su edad y nivel educativo. El análisis transversal muestra asociaciones negativas educación-matrimonio en ambos sexos y educación-participación en ellas por comparación con ellos, que junto con una mayor segregación de género en las casadas sugieren que estas soportan un sesgo específico de familia que dificulta su presencia en el mercado. La percepción individual de la interferencia de la familia lo confirma, pues son ellas quienes adolecen primordialmente de problemas de conciliación familia-trabajo, incluso en edades inferiores a 44 años donde están más educadas que sus maridos y la igualdad de género es un valor social asentado. El análisis longitudinal cuantifica, con estimaciones Logit multinomial, la desventaja de las casadas en términos de probabilidad de entrada impedida al mercado de las inactivas y de probabilidad de abandono prematuro de las ocupadas, debido a problemas de conciliación familia-trabajo. En breve, las responsabilidades familiares excluyen del mercado a las mujeres casadas con independencia de su edad y educación.
Interpretaciones de los estudiantes de educación secundaria sobre la masculinidad: por una pedagogía de género en los centros escolares
Authors: Ceballos Fernández Marta
Published: August 2024

En el presente artículo se investigan las opiniones y las valoraciones de estudiantes-varones de cuarto de Educación Secundaria Obligatoria (ESO) sobre la masculinidad. Se realiza un análisis sobre la comprensión de la identidad de género masculina considerando elementos aledaños como la feminidad y la sexualidad. En la investigación participan tres centros escolares del Principado de Asturias, examinándose este tópico en diversas culturas escolares. A través del empleo de entrevistas y de la conducción de grupos de discusión se efectúa un análisis discursivo sobre los temas reseñados. Los hallazgos más importantes indican que los adolescentes interpretan la masculinidad desde una visión género-normativa que perpetúa el esquematismo de género, consolida la condición heterosexual de la masculinidad y su ordenamiento frente a la feminidad. Estos resultados refuerzan la convicción de trabajar a favor de una pedagogía de género en los centros escolares. Concluimos destacando unas propuestas pedagógicas en este orden.
Mujeres Requesens y la disputa por la baronía de Riba-roja (1520-1584): un conflicto familiar en la Valencia moderna
Authors: Finestrat Martínez Aitana
Published: August 2024

En este estudio se presenta un largo pleito provocado por la posesión de una baronía, la de Riba-roja, entregada como herencia a Joana Mateua de Requesens, quien a su vez pretendió legar a su hija tras su muerte. La disputa por dicha posesión no se pudo asentar fácilmente y se alargó todo el siglo XVI, siendo protagonizada por varias de las mujeres pertenecientes a la importante familia Requesens e implicando a instituciones religiosas y civiles. El estudio detallado de este pleito y todas sus implicaciones muestra las dinámicas sociales del momento; las posibilidades para heredar y métodos empleados para llevar adelante un pleito siendo una mujer; las tramas y ardides utilizados por una religiosa encerrada; y los intereses y resortes que se activaron dentro de una misma familia que se disputaba una posesión de buenos rendimientos económicos, pero que también había puesto en juego sentimientos como el orgullo y el honor.

Published: August 2024

Background and Aim: Tick and flea infestations in dogs are significant concerns for both dog owners and veterinarians in Thailand. The country’s climate provides an optimal environment for the proliferation of ticks and fleas, thereby increasing the risk of diseases transmitted by these parasites. At present, a diverse range of tick and flea prevention products is available on the market. This study aimed to investigate the factors influencing the choice of tick and flea prevention products among dog owners and veterinarians in Thailand.

Materials and Methods: Questionnaires were distributed both online and in-person to collect data from dog owners and veterinarians. The data collection period spanned from September 1, 2022, to August 31, 2023. A total of 994 respondents, consisting of 828 dog owners and 166 veterinarians, participated in the questionnaire and were included in this study. The data were then subjected to descriptive statistics and Chi-square test.

Results: The results indicated that most dog owners consider chewable products to be the most effective form of tick and flea prevention, followed by sprays and spot-on treatments. Statistically significant factors (p < 0.05) affecting the frequency of use of tick and flea prevention products were identified, including dog breed, number of owned dogs, and owners’ awareness of tick and flea issues in dogs. Most dog owners tend to use these products when their dogs are infected with ticks or fleas. In addition, owners of a single dog tended to use these products regularly compared to those with multiple dogs. Notably, some dog owners (10.99%) used unregistered products. Among veterinarians, it was observed that dog owners followed the recommendations provided by veterinarians (80.12%). In most cases, veterinarians recommend various tick and flea prevention products (74.10%). The most influential factor affecting product selection is suitability for the individual animal.

Conclusion: This study provides insights for veterinarians and relevant stakeholders regarding the factors and attitudes that influence dog owners’ selection of tick and flea prevention products. This knowledge can contribute to better planning for ectoparasite prevention. In addition, effective communication from veterinarians can increase owner awareness of the importance of tick and flea prevention, thereby reducing the incidence of diseases transmitted by ticks and fleas.

Published: August 2024

Segundo a OMS, o envelhecimento é saudável quando a capacidade funcional e o bem-estar do indivíduo são preservados. Com o aumento da população idosa, há um aumento da necessidade de políticas de saúde voltadas para este público. Em relação ao corpo idoso feminino, existem desvantagens históricas e culturais, a imagem corporal, expectativas e reflexões que a idosa tem de si, ditam a percepção de corpo e saúde da mulher. Assim, é importante trazer à luz as reflexões delas diante da realidade. Compreender o olhar de mulheres idosas sobre o corpo delas e a compreensão da ancestralidade no que diz respeito à forma como esse grupo se percebe. Esta pesquisa é qualitativa, transversal, observacional e analítica, com amostra intencional, composta por idosas da Universidade Aberta à Terceira Idade, da Universidade Estadual do Piauí. A coleta ocorreu por meio de um roteiro semiestruturado composto por questões abertas, os resultados foram submetidos à Técnica de Análise de Conteúdo de Laurence Bardin (2004). A partir das entrevistas, foi possível chegar às categorias “Movimento, potencialidades e barreiras”; “Figura materna de referência”; “Autoaprendizado: a vivência como fonte de ensino sobre o corpo”; e “Autoimagem, complexos corporais e visões relacionadas ao corpo gordo”.

Este estudo investiga a relevância da Educação de Jovens e Adultos (EJA) nos contextos de privação de liberdade, fundamentado na perspectiva da educação popular. Utilizando uma abordagem qualiquantitativa, foram analisados dados estatísticos do sistema prisional brasileiro para examinar o papel da EJA na educação de indivíduos privados de liberdade. Embora prometa explorar a relação entre EJA prisional e educação popular, o estudo revela lacunas na concretização dessa conexão. Também foram discutidas críticas construtivas acerca da necessidade de maior articulação entre práticas educativas, currículos flexíveis e trabalho interdisciplinar para fortalecer o impacto da EJA nessas comunidades. Conclui-se que a educação em prisões não se limita à alfabetização, mas oferece oportunidades para a reconstrução da cidadania e a reintegração social, destacando-se como um instrumento fundamental para romper ciclos de exclusão e criminalidade, de modo a avançar em direção a uma sociedade mais justa e inclusiva.

Published: August 2024

Kültür, bir toplumun ahlakını, inançlarını, yaşam tarzlarını ve toplumla ilgili tüm değerlerini kapsamaktadır. Bu açıdan bakıldığında, her toplum hem kendi kültürünü hem de diğer toplumların kültürünü merak etmekte ve ilgi duymaktadır. Özellikle kültürün nesilden nesile aktarılması, onun miras değerini ortaya koymakta ve öneminin daha da artmasına katkı sağlamaktadır. Bu önemden dolayı Kültürel miras son yıllarda üzerinde önemle durulan bir kavram haline gelmiştir. Bu araştırmanın amacı; Karabük’te görev yapan öğretmenlerin, Karabük’te bulunan kültürel miras unsurlarına ilişkin farkındalık ve deneyim düzeylerinin tespit edilmesidir. Bu amaçla araştırmada nicel araştırma yöntemlerinden biri olan anket tekniği ile 390 öğretmenden veriler toplanmıştır. Araştırmanın temel sonuçlarına göre, öğretmenlerin cinsiyet, yaş ve medeni durumlarına göre kültürel miras farkındalığı farklılık göstermezken, ikamet süreleri açısından kültürel miras farkındalığını farklı değerlendirdikleri tespit edilmiştir. Diğer yandan başka bir sonuca göre, öğretmenlerin yaşları, medeni durumları, görev yaptıkları okul türleri ve bulundukları yerdeki ikamet süreleri açısından, kültürel miras deneyimini farklı değerlendirdikleri tespit edilirken, öğretmenlerin cinsiyetlerine göre böyle bir farklılığın olmadığı ortaya çıkmıştır. Bu sonuçlar doğrultusunda özellikle öğretmenler özelinde bazı öneriler getirilmiştir.

Küreselleşme, ülkeleri ticaret akışları, sermaye piyasalarının açılması, teknolojik yenilikler, kültürel ve politik kararlar açısından birbirine bağlayan bir olgudur. Hızlı ekonomik büyüme ve kalkınma için küreselleşmenin biyolojik çeşitlilik üzerindeki olumsuz etkisi kolaylıkla göz ardı edilebilmektedir. Bu bakımdan küreselleşmenin ekonomik büyüme üzerinde doğrudan çevre üzerinde ise dolaylı bir etkisinin söz konusu olduğu söylenebilir. Çalışma, Türkiye için 1980-2019 yılları arasında kişi başına reel gayri safi yurt içi hasıla (GSYH) ile küreselleşme İsviçre Ekonomi Araştırmaları Enstitüsü (KOF) veri tabanından elde edilen ekonomik, politik ve sosyal küreselleşmenin ekolojik ayak izi üzerindeki etkisini incelemeyi amaçlamıştır. Ekonometrik yöntem olarak Pesaran vd. (2001) tarafından önerilen gecikmesi dağıtılmış otoregresif sınır testi (ARDL) kullanılmıştır. ARDL kısa dönem ve uzun dönem bulgularına göre kişi başına reel GSYH ve sosyal küreselleşme ekolojik ayak izini artırmakta iken, ekonomik ve politik küreselleşmenin herhangi bir etkisi bulunamamıştır.
OSMANLI DEVLETİ’NDE TELGRAF

Telgraf, belli aşamalara uğrayarak bulunmuş bir icattır. Elektrikli telgrafın icadına kadar telgrafın telgraf olmasını sağlayan bazı aşamalar şunlardır; Felemenkli Jansen’ının (1650’de) dürbünü, zamanla haberleşme için kullanılmaya başlanmış ancak dürbünün göremediği yerlerden de haber alınabilmesi için daha ileri fikirler ortaya çıkmıştır. Bunun için ilk önemli adım Claude Chappe’ın havai telgraf sistemi olmuş ama bu fikre elektrik mekanizmasını da ekleyen ünlü ressam 1837 yılında Samuel F.B. Mors, elektrikli telgrafın ününü kazanan kişi olmuştur
Osmanlı Devleti’nde ilk Telgraf hatlarının çekimi Fransızlara verildi. 15 Eylül 1855’de Telgraf İdaresi resmi olarak açıldı ve çalışmalara başlandı. Telgraf İdaresi’nin en mühim çalışması ise Fransızca olan telgraf dilinin Türkçeleştirilmesi olmuştur. Telgrafhanelerle ilgili 17 Şubat 1857 tarihinde bir nizamname yayımlandı. Bu nizamname de telgraf memurlarının eğitimi ve çalışma şekilleri ile ilgili hükümler yer aldı. Telgraf gereçlerinin üretimi için de, Telgraf Müdürü Fevzi Bey'in gayretleriyle Mayıs 1869'da Telgraf Fabrikası açıldı. Kısa sürede Osmanlı Devletinde hem Rumeli bölgesinde hem de Anadolu bölgesinde bir haberleşme ağı kuruldu. Ancak halkın bu haberleşme sistemini kullanması pahalıydı. Bu pahalılık nedeni ile 1864’de telgraf fiyatlarında ıslaha gidilip fiyatlar düşürüldü. Zamanla tarifeler üzerinde farklı çalışmalar yapıldı.

Çağdaş toplumların önemli gündemlerinden biri toplumsal kalkınmadır. Toplumsal kalkınma çok boyutlu bir hedef olarak ekonomi, kültür, eğitim vb. birçok alandaki gelişmeleri kapsamaktadır. Türkiye’de ilk defa 2015 yılında TÜİK tarafından oluşturulan illerde yaşam endeksi verilerinde illerin belirli bir takım kriterlere göre sıralandığı bilinmektedir. Bunun dışında başta eğitim olmak üzere belirli bir takım alanlarda örneğin sınav sonuçlarına göre benzer sıralamaların yapıldığına da şahit olunmaktadır. Bu tür sıralandırmalar ya da derecelendirmelerden hareketle her bir il için bir takım değerlendirmelerin de yapılmakta olduğu hatta bu değerlendirmelerin yerel veya ulusal medya organlarına yansıdığı görülmektedir. Bu çerçevede bazı illerin üst sıralarda yer alması bazılarının da alt sıralarda yer alması nedeniyle başarı ve başarısızlık tespitlerinin yapıldığını da gözlemek mümkündür. Çalışma yöntem olarak, TÜİK’in verilerine dayalı istatistik analizine ve konuyu kırsal kalkınma sorunuyla ilişkilendiren niteliksel değerlendirmelere dayanmaktadır. Bu çalışmada özellikle eğitim endeksi başta olmak üzere çeşitli kriterlere göre oluşturulan endekslerin değerlendirilmesinde illerin kır ve kent nüfus oranlarının dikkate alınmasının gerekliliği vurgulanmakta, özellikle Afyonkarahisar İli’nin çevresine göre nispi olarak yüksek olan kırsal nüfus oranının il düzeyinde sıralamalara negatif yönlü yansıdığı üzerinde durulmakta ve sonuç olarak Türkiye’de benzer durumlar açısından kırsal kalkınmanın önemine vurgu yapılmaktadır.

Effect of integrated use of organic and inorganic sources of nutrients on growth and yield of black gram (Vigna mungo (L.) Hepper)
Authors: Sharma Saumya , Gite Dipak , Misal Nitin , Darvhankar Mayur
Published: August 2024

The present research study aimed to evaluate the combined influence of inorganic and organic nutrient sources on the growth and yield parameters of black gram (Vigna mungo (L.) Hepper). The result indicated that using a combination of 50% of the recommended dose of fertilizer and 50% vermicompost had a significant positive impact on growth attributes, yield parameters, and biochemical parameters. These findings suggests that the simultaneous application of organic and inorganic fertilizers can effectively improve soil fertility and crop yield. Notably, integrating 50% of the recommended fertilizer dose with 50% vermicompost proved to be particularly beneficial in enhancing both the growth and yield of black gram compared to other treatments, including the control group.
Molecular interactions and genetic improvements of fungal entomopathogens
Authors: Sumaiya Parveen S. , Vinu Radha R. , Philip Sridhar R.
Published: August 2024

In the natural world, entomopathogenic fungi are crucial for maintaining the population balances of agricultural pests and disease-carrying organisms. It is impossible to fully address the limitations of mycoinsecticides for field pest management by enhancing a single fungal biocontrol property. Thus, it is desirable to use genetic engineering to increase the biocontrol capability of entomopathogenic fungi in numerous ways. By breaching the host's cuticle, they have the capability to propagate. When coupled with attempts to boost fungal virulence and stress resilience through genetic modifications, comprehending entomopathogenic fungi could improve the economic effectiveness of employing mycoinsecticides for pest control in agricultural environments. Additional research is necessary to elucidate the gene-for-gene connections in fungus-insect interaction models, given the advancing knowledge of fungal diseases in plants and humans.

Published: August 2024

Natural growth and development of plants in cold arid regions are affected by drought stress, limited water availability and sandy soils, thereby reducing growth and productivity. This study was aimed at examining the combined effects of boron and zinc supplementation on the physicochemical responses of carrots in high-altitude cold desert environments using different concentrations of these micronutrients. Experiment was carried out in randomized block design (RBD) and treatment means were differentiated using the Tukey’s test at a 0.05 level of probability. It was observed that in comparison to control, the foliar application of Borax @ 0.1% + ZnSO4 @ 0.5% significantly improved root diameter, average root weight, yield, sucrose content, total sugar, sweetness index, and total sweetness index in carrots. The maximum chlorophyll content (9.29 CCI) in carrot leaf was observed by foliar application of Borax @ 0.2% + ZnSO4 @ 1.0%, which is statistically at par with foliar application of Borax @ 0.1% + ZnSO4 @ 1.0% (9.27 CCI). However, the highest glucose and fructose content was observed with a foliar application of Borax @ 0.1%. The highest nitrate (351.08 mg/100 g) content was recorded in the combined foliar application of Borax @ 0.1% + ZnSO4 @ 0.5% (T5). Among the treatments, maximum values of sulphur (210.73 mg/100 g) in carrot root were observed in Borax @ 0.2% + ZnSO4 @ 0.5%.
Increased resting lactate levels and reduced carbohydrate intake cause νLa.max underestimation by reducing net lactate accumulation—A pilot study in young adults

Published: August 2024

Modulation of testing conditions such as resting lactate (Larest) levels or carbohydrate intake may affect the calculation of the maximal glycolytic rate (νLa.max). To evaluate the impact of elevated Larest as well as reduced and increased carbohydrate availability on νLa.max in running sprints (RST), twenty‐one participants completed five 15‐s RST tests on a running track under five different conditions: (I). baseline: Larest ≤1.5 mmol·L−1; (II). Lactate+: Larest ≥2.5 mmol·L−1; (III). CHO−: carbohydrate intake: ≤ 1 g·kg−1 BW d−1 for 3 days; (IV). CHO+: carbohydrate intake: ≥ 9 g·kg−1 BW d−1 for one day; and (V). acuteCHO: 500 mL glucose containing beverage consumed before RST. νLa.max was significantly reduced in lactate+ and CHO− conditions compared to the baseline RST, due to a reduction in the arithmetic mean delta (∆) between Lapeak and Larest lactate concentration (Lapeak, mmol · L−1). AcuteCHO led to an increase in Larest compared to baseline, CHO− and CHO+ with a high interindividual variability but did not significantly reduce νLa.max. Therefore, avoiding low carbohydrate nutrition before νLa.max testing, along with carefully adjusting Larest to below ≤1.5 mmol·L‐1, is crucial to prevent the unintentional underestimation of νLa.max.

Analytical verification of the Atellica VTLi point of care high sensitivity troponin I assay
Authors: Florkowski Christopher M. , Buchan Vanessa , Li Bobby V. , Taylor Felicity , Phan Minh , Than Martin , Pickering John W.
Published: August 2024

Objectives

The Siemens Point-of-Care Testing (POC) Atellica® VTLi high-sensitivity troponin I (hsTnI) device has been previously validated. Verification independently provides evidence that an analytical procedure fulfils concordance with laboratory assays, imprecision, and hemolysis interference requirements.

Methods

Five whole blood samples spanning the measuring interval were analysed 20 times in succession. Hemolysis interference was assessed at three troponin concentrations by spiking five hemolysate concentrations to plasma to achieve free hemoglobin concentrations 35–1,000 mg/dL. Concordance between whole blood (VTLi) and plasma on laboratory analysers (Beckman, Roche, Siemens) was assessed by Pearson correlation and kappa statistics at the (LOQ) and upper reference limit (URL). This was repeated for frozen plasma samples.

Results

Coefficients of variation for whole blood were <10 % for whole blood troponin concentrations of 9.2 and 15.9 ng/L, thus below the URL. Hemolysis positively interfered; at 250 mg/dL affecting the low troponin sample (+3 ng/L; +60 %) and high troponin sample (+37 ng/L; +24 %). Correlation coefficients were 0.98, 0.90 and 0.97 between VTLi and Beckman, Roche and Siemens assays respectively. Corresponding kappa statistics were 0.80, 0.73 and 0.84 at the LOQ and 0.70, 0.44 and 0.67 at the URL.

Conclusions

Concordances between VTLi and laboratory assays were at least non-inferior to those between laboratory assays. Imprecision met manufacturer claims and was consistent with a high sensitivity assay. There is potential for hemolysis interference, highlighting the need for quality samples. The results support performance characteristics previously reported in validation studies, and the device offers acceptable performance for use within intended medical settings.
