Authors: Moreno-Barriga Monica , Noguera-Cundar Andrés , Castro-Cepeda Lidia
Published: September 2024

The present study has as objective the analysis and characterization of a sample of an Ecuadorian feldspar, by means of XRD, SEM and TGA techniques, for the microstructural analysis of mineral phase and chemical composition. Qualitative and quantitative X-ray diffraction analysis by Rietveld refinement revealed that this feldspar is composed of 33.31% Albite, 15.70% Quartz and a large percentage by weight of 50.99% amorphous material. To validate these results, the uncertainty of the measurement was investigated and calculated by statistical analysis of standard deviation, giving as results an uncertainty error of ±0.87 wt%, ±0.23 wt% and ±0.89 wt% respectively for the percentages by weight of the minerals found in this analysis. The result by SEM shows the presence of Albite in the feldspar exhibiting laminar twinning and characterized by randomly dispersed spherical quartz and plagioclase inclusions.

Published: September 2024

High concentrations of heavy metals in urban watersheds can offer harmful effects to human health and have contributed to environmental contamination. The present work aims to evaluate the total concentration of Zn (zinc), Mg (magnesium), lead (Pb), Cr (chromium), manganese (Mn) and Ni (nickel) analyzed according to FAAS—Flame Atomic Absorption Spectrometry, in samples of the aquatic macrophyte Egeria densa present in the urban stretch of the Cascavel River watershed, Guarapuava, PR; and specific objectives to identify the potential sources of contamination by heavy metals and to obtain physical parameters of the water. The elements zinc, magnesium, manganese and lead showed higher potential emissions upstream, a fact associated with the proximity of the industrial zone of Guarapuava. It is likely that the increase in electrical conductivity values at the upstream points is related to the discharge of domestic effluents. The decrease of conductivity and total dissolved solids in the sample points occurs downstream, corresponding to the lower topography of the study area and the end of the urban stretch of the Cascavel River basin. Despite the concentrations of heavy metals being considered critical, the plant showed efficiency in bioaccumulation of these chemical elements, being an effective tool for research and environmental assessment, and aquatic macrophytes can be the basis for biomonitoring studies of urban environments impacted by heavy metals.

Published: September 2024

Objective: To assess the quality of whole wheat products, a method for determining alkylresorcinols (ARs)—markers of whole wheat, black wheat, and other cereal products—was developed. Methods: The study focused on wheat and black wheat, using factorial design to evaluate the impact of extraction solvents (acetone, alcohol, and ethyl acetate), extraction techniques (ultrasonic extraction for 30 or 60 minutes, and shaking overnight at room temperature), and sample forms (granules or flour) on AR determination. AR detection conditions were optimized by comparing chromatographic settings and fluorescence scanning wavelengths. The method's effectiveness was validated by measuring AR content in various commercially available cereals. Results: Considering reagent toxicity and efficiency, the optimal procedure involved ultrasonically extracting comminuted samples with ethanol for 30 minutes, then analyzing with a Waters CORTES-C18 column using an ethanol: acetonitrile (30:70, v:v) mobile phase. Fluorescence detection was performed at an excitation wavelength of 272 nm and an emission wavelength of 296 nm. The method had a linear range of 0.050–10.0 µg/mL with an R² ≥ 0.9999. Precision experiments showed an RSD of less than 5%, and spiked recovery rates ranged from 94.5% to 104%. The total AR content was 47.9–54.3 mg/100 g in commercially available wheat and 53.6–60.9 mg/100 g in black wheat. Conclusion: The liquid-fluorescence method established in this study effectively and rapidly separates ARs from wheat and black wheat, offering advantages of simplicity, high sensitivity, and accuracy.

Authors: Chen Yukun , Liu Congcong , Liang Weiyang
Published: September 2024

Objective: To develop and compare methods for quantifying residual free formaldehyde in vaccines using pre-column and post-column derivatization liquid chromatography, and to assess the consistency between these methods. Methods: For pre-column derivatization, we used a Shimadzu LC-20AT liquid chromatograph equipped with an SPD-20A UV detector. Separation was achieved with a mobile phase consisting of 60% acetonitrile at a flow rate of 0. 8 mL·min−1 and a column temperature of 40 ℃. Detection was performed at 360 nm using a Kromasil 100-5-C18 (250 mm × 4.6 mm) column. For post-column derivatization, we employed a Shimadzu LC-20AT liquid chromatograph with an SPD-M20A diode array detector and a vector derivative device. Separation was conducted with a mobile phase of 0.2% (V/V) phosphoric acid at a flow rate of 1.0 mL·min−1 and a column temperature of 25 ℃. Detection was carried out at 412 nm using a Chrom Core AQ-C18 (250 mm × 4.6 mm) column. The derivatization solution was acetate buffer, flowing at 0.5 mL·min−1 and maintained at 100 ℃. Both methods were evaluated for precision, repeatability, and sample recovery, with statistical significance assessed using F-test and t-test. Results: The pre-column derivatization method exhibited linearity over the range of 0.025–100 μg·mL−1 (R = 0.9999, n = 12). Precision showed an RSD value of 0.06%, and repeatability ranged from 0.3% to 1.4%. Average recoveries were between 97.3% and 104.8%, with RSD values from 0.7% to 2.9%. The limit of quantitation (LOQ) was 0.02 μg·mL−1, and the limit of detection (LOD) was 0.01 μg·mL−1. The post-column derivatization method demonstrated linearity in the same range (0.025–100 μg·mL−1, R = 0.9999, n = 12). Precision showed an RSD value of 0.02%, and repeatability ranged from 0.7% to 3.5%. Average recoveries were between 105.6% and 114.6%, with RSD values from 0.3% to 1.9%. The LOQ was 0.02 μg·mL−1, and the LOD was 0.006 μg·mL−1. Statistical analysis indicated that both methods produced comparable results. Conclusion: Both pre-column and post-column derivatization liquid chromatography methods are simple, accurate, and highly sensitive, making them suitable for determining residual free formaldehyde in vaccines.

Authors: Ma Jingzhi
Published: September 2024

A rapid and straightforward method has been devised for direct analysis of SiO2, Al2O3, Fe, MgO, CaO, K2O, Mn, TiO2, P, and Zn in manganese ore samples using an X-ray fluorescence spectrometer (XRF). The method employs a glass fusion technique with a flux composed of Li2B4O7, LiBO2, and LiF (in a mass ratio of 45:10:5), NH4NO3 as an oxidizing agent, and LiBr as a stripping agent. The method's experimental parameters were fine-tuned, and its performance metrics were assessed. The proposed method was used to analyze the certified reference materials GBW07261 to GBW07266, yielding relative standard deviations (RSD, n = 12) below 2%. Accuracy was verified using synthetic samples, and the obtained results were in line with the certified values.

A novel method for glucose detection using dual-modal carbon dots for colorimetric and ratiometric fluorescence analysis
Authors: Yuan Chunling , Yao Xiaotiao , Xu Yuanjin , Qin Xiu , Shi Rui , Cheng Shiqi , Wang Yilin
Published: September 2024

Iron-based nitrogen co-doped carbon dots (Fe, N-CDs) were synthesized from taro leaf biomass via a hydrothermal process using ammonium ferric sulfate dodecahydrate and urea. The synthesized Fe, N-CDs exhibited peroxidase-like activity and strong fluorescence at 450 nm. A dual-mode colorimetric/ratiometric fluorescence assay for hydrogen peroxide (H2O2) detection was developed using Fe, N-CDs and o-phenylenediamine (OPD) as probes. In the presence of H2O2, OPD was oxidized to 2,3-diaminophenazine (DAP), which is yellow and absorbs at 420 nm. Under 360 nm excitation, DAP emits fluorescence at 550 nm and quenches the fluorescence of Fe, N-CDs at 450 nm due to the internal fluorescence filtering effect. This enables the quantitative analysis of H2O2 using the absorbance at 420 nm (A420) and the fluorescence intensity ratio of DAP to Fe, N-CDs (I550/I450). Since glucose oxidase can convert glucose to H2O2, the assay was extended to glucose determination. At pH 5.4, 40 ℃, with 1.75 mmol/L OPD and a 25-minute reaction time, the method showed a linear relationship between the A420 and I550/I450 values and glucose concentration in the range of 1.0~100 μmol/L, with detection limits of 0.8 μmol/L (colorimetry) and 0.6 μmol/L (ratiometry). The method was validated for glucose detection in human serum.

Published: September 2024

Haemophilus influenzae type b is an important human pathogen causing several invasive diseases in children under five years of age, against which glycoconjugated vaccines based on polyribosylribitol phosphate have been licensed. Quimi-Hib® is the first and only vaccine against this pathogen using the polysaccharide obtained by chemical synthesis. The Active Pharmaceutical Ingredient is produced by the Center for Genetic Engineering and Biotechnology and is obtained from its conjugation to tetanus toxoid. In the present report, a characterization of polyribosylribitol phosphate was performed using the high performance molecular exclusion chromatography technique with ultraviolet detection at 215 nm. Three batches were evaluated in the study and the elution profile was determined on a SuperdexTM 75 10/300 GL Increase column with a purity percent of 77.42 ± 8.97 and an average molar mass of 7381 Da ± 210.93. The main impurity present in polyribosylribitol phosphate is dimethyl sulfoxide, the solvent used in the activation reaction with the N-hydroxysuccinimidyl ester of β-maleimidopropionic acid. The polyribosylribitol phosphate was purified by filtration with a 2000 Da Amicon Ultra-15 to 99.1% purity and conjugated to tetanus toxoid. The yield of the conjugation reaction with the purified polysaccharide was 30.0% ± 1.77% which shows no significant difference with the control which was 33.7% ± 3.57% demonstrating that dimethyl sulfoxide does not affect the performance of the conjugation reaction.

How clean is clean enough? : infection prevention and control in animal healthcare
Authors: Alsing Johansson Todd
Published: September 2024

Microorganisms in the environment and on equipment in animal healthcare facilities may constitute a risk of healthcare-associated infections (HAIs). Knowledge of the bacterial load as well as factors influencing the bacterial load is helpful in establishing infection prevention and control (IPC) routines to reduce the risk of HAIs. Cleaning and disinfection of environmental surfaces and equipment is an important IPC measure to reduce the risk of environmental spread of pathogens and incidence of HAIs. The overall aim of the thesis was to improve IPC in animal healthcare by studying the bacterial load, before and after cleaning and disinfection, in the environment and on equipment, by passive air and surface sampling. The bacterial load was generally low in air and on high-touch and near-patient surfaces in the operating room (OR) and the ultrasound room (UR). On near-patient surfaces in dog cages the bacterial load was generally low after decontamination, except after microfibre cleaning of the floor. The bacterial load was high on nearpatient surfaces and dental handpieces after equine dental care, and after decontamination the bacterial load on near-patient surfaces was generally low, but on dental handpieces the bacterial load was still high. Genes conveying resistance to chlorhexidine and quaternary ammonium compounds were identified in environmental staphylococci from the OR and the UR. In conclusion, this thesis present a generally low bacterial load, except after microfibre-cleaning of the floor in dog cages and after decontamination of dental handpieces. This indicates a need for evidence-based cleaning and disinfection routines for environmental surfaces and equipment in animal healthcare, to reduce the risk of HAIs.

Published: September 2024

Aim: Pine Processionary Caterpillar (Thaumetopoea pityocampa) envenomations have become increasingly relevant due to the species' expanding habitat, influenced by global climate change. These envenomations present unique challenges, particularly in regions previously unexposed to this species. This study aims to retrospectively analyze envenomations caused by the Pine Processionary Caterpillar over a ten-year period, evaluating the frequency, clinical manifestations, and the impact of climate change on these cases.

Material and Methods: We reviewed patient records from four different hospitals between January 2014 and May 2024, focusing on cases with confirmed contact or exposure to the caterpillar. Data on demographics, clinical findings, treatment approaches, and seasonal trends were collected and analyzed.

Results: A total of 53 patients were included, with a nearly equal distribution between male and female patients. The most affected areas were the neck and face, primarily due to outdoor activities in pine forests. The peak incidence of envenomations was observed in May and June. Antihistamines, particularly intramuscular administration, were the most common treatment, with racemic epinephrine used in cases of severe reactions. Notably, the northward expansion of the caterpillar's habitat has been linked to increasing cases of envenomation.

Conclusion: The findings highlight the need for heightened awareness and preventive measures, especially during the caterpillar's peak activity season. As climate change continues to alter the distribution of Thaumetopoea pityocampa, regions unaccustomed to such exposures must prepare for the associated health risks.
Conducting Hermeneutic Research in International Settings: Philosophical, Practical, and Ethical Considerations
Authors: VanLeeuwen Charlene A. , Guo-Brennan Linyuan , Weeks Lori E.
Published: September 2024

Hermeneutics has been theorized and applied as a philosophical framework and interpretive research methodology which pays particular attention to linguistic, social, cultural, and historical contexts to understand the life world and human experiences. While adopted as a qualitative research approach in the fields of education, nursing, psychology, and legal studies, its use is emerging in other human service disciplines. The rich philosophical and theoretical legacy embedded in this research methodology often presents unique challenges and a steep learning curve for researchers, particularly when the research is conducted in international settings. Drawing from insights gained from two hermeneutic studies conducted in Kenya and China, this paper presents considerations for designing a hermeneutic research inquiry. In addition to philosophical, practical, and ethical issues researchers need to consider when designing and implementing hermeneutic studies in international settings, we examine factors and strategies to facilitate successful data collection and interpretation.
Emerging Horizons, Part Two. Harmony’s Story: Answering the Big Question
Authors: Lang Dr. Michael J , Laing Dr. Catherine M
Published: September 2024

This second installment of the Emerging Horizons series explores Harmony’s digital storytelling (DST) experience (please see the introductory editorial to the series, Crafting Meaning, Cultivating Understanding, to access the film). In this article I lean on the philosophy of Paul Ricœur to suggest that 1) the metaphorical possibilities of DST could enable Adolescent and Young Adult (AYA) cancer survivors to come to a deeper understanding of their own cancer experiences and 2) the process of “emplotment” in the creation of a digital story has the power to transform the random and coincidental, pre-narrative experience of cancer into a meaningful whole. I conclude by discussing how attaching meaning to, and learning from, an otherwise meaningless cancer experience through the DST process, can help AYA cancer survivors construct their own answer to the “big question” of cancer in young adulthood.
Gadamerian Hermeneutics with Intersectionality as an Analytical Lens
Authors: Haghiri-Vijeh Roya , McDonald Dr. Carol
Published: September 2024

For decades, hermeneutics has been used as a qualitative research approach to enhance understanding of the experiences of individuals within a particular context. However, after reviewing the literature, it became evident that only a few published articles use intersectionality as an analytical lens along with Gadamerian hermeneutics. This article draws on examples from a 2021 study that explored experiences of LGBTQI+ migrants with healthcare providers. Utilizing the philosophical underpinnings of Gadamerian hermeneutics and the theoretical foundations of intersectionality, the confluences and the tensions between these two approaches is explored. Moreover, suggestions are provided for how intersectionality as an analytical lens can expand understandings and interpretations of research findings using Gadamerian hermeneutics.
Death, Dying, and Credibility in Long-Term Care: How Healthcare Aides Were the Voiceless Other During the COVID-19 Pandemic
Authors: Stelfox Katherine
Published: September 2024

Confronted by an unprecedented number of deaths in Long-Term Care (LTC) during the COVID-19 pandemic, society had no choice but to engage in a public discourse about the state of death and dying in LTC, and the staff who were caring for residents: healthcare aides. Despite being places where older adults die, death and dying has largely been hidden within LTC homes, serving to complicate and conceal healthcare aides’ experiences at a time when LTC residents were visibly dying. Although being the subject of public discourse, healthcare aides remained voiceless during the pandemic, their experiences of caring for dying residents overlooked by the testimony of experts. Instead of healthcare aides being invited into a conversation to share their unique knowledge of death and dying in LTC, namely through that of touch and practical wisdom, they experienced a lack of epistemic credibility, having been served a testimonial injustice.
The Effects of Context-Rich Problems on Motivation and Learning in Mechanical Physics
Authors: Giachini Lisa , Cabot Isabelle
Published: September 2024

This study examines the effects of the pedagogical use of context-rich problems on motivation and learning, as compared to traditional problems, in mechanical physics courses at the college level. The results indicate that the treatment has appreciable outcomes on conceptual learning gain, on the perception of task value and on a perceived sense of competence. Moreover, the affected motivational variables exhibit a considerable positive correlation with learning gain. A linear regression analysis shows that the best predictors of learning gain are perceived sense of competence and interest. The former acts as the main learning gain predictor when the theme of the problem is imposed by the teacher, whereas the latter becomes the best predictor when students can choose the theme among different possibilities, situations that seem to be more conducive to learning gain. Therefore, offering a choice of themes, while using context-rich problems, appears to increase the students’ emotional reactions, making this pedagogical device a promising tool for achieving learning gains.

One of the figures of Alash, recognized not only as a poet, but also as an outstanding translator, is Turagul Abayevich. The article delves into the multifaceted creative legacy of Turagul Kunanbayev, with a special emphasis on his endeavors in literary translation. Kunanbayev, a prominent figure in Alash-Orda, is examined in terms of his stance within literary translation and the stylistic nuances he employed. The analysis primarily revolves around translation transformations, using specific works such as “The Story of Keesh” by Jack London, “Chelkash” by Maxim Gorky, and pieces by Alexander Neverov like “Marya the Bolshevik” and “I Want to Live”. The approach considers the time period and contemporary demands placed on translation. Various aspects of the translator’s craft— psychological, literary, linguistic, and societal—are taken into consideration. It is argued that Kunanbayev’s translations were in line with the requirements of their era. Through methods of comparison and contrast, typological patterns are identified, shedding light on the translator’s epistemological and cognitive approaches. Furthermore, Kunanbayev’s translations are scrutinized through the lens of national interests, revealing his distinctive artistic identity. The comparative analysis concludes that literary translations during the early twentieth century predominantly favored a free approach, as opposed to strict literal translation methods.
