Exploring the Correlation Between Salt Tolerance and Seed Nutritional Value of Different Quinoa Genotypes Grown Under Saharan Climatic Conditions

Quinoa is an annual pseudocereal highly adapted to extreme environments and has become, at this point in time, an extremely popular food due to its exceptional and high nutritional quality. This study aims to investigate the association of quinoa salt tolerance at an early developmental stage with its grain nutritional value under the effect of severe climatic hurdles. The current findings revealed a significant variability between genotypes in salt response attributes at the first development stage, where genotypes Amarilla Sacaca (thereafter, A. Sacaca) and QQ57 exhibited high salt tolerance thresholds with a low salt sensitivity index (SI), and a high capacity for Na+ sequestration into vacuoles. A significant positive association was detected between salt tolerance degree and yield parameters, saponins (SAPs), and minerals contents, where genotype A. Sacaca exhibited the highest SAP content with 3.84 mg.g−1 and the highest amounts of K, Ca, P, and Fe. The analysis of fatty acid composition demonstrated a high significant negative correlation between crude fat content and salt SI, and between yield parameters. Despite its low harvest index (HI) and low seed oil content, the salt-tolerant genotype A. Sacaca showed a high nutritional quality for seed oil according to its lowest ω6/ω3 ratio (5.6/1) and lowest level of atherogenicity index (AI). The genotype 115R, defined as the most sensitive to salt stress, exhibited a high seed oil quality due to its low lipid peroxidation susceptibility as reflected by its oxidative susceptibility and peroxidizability indexes. The significance of this study includes the identification of valuable quinoa genotypes showing high efficiency in growth and yield under severe stress accompanied by a high nutritional value satisfying the market requirements for healthy, nutritious, and safe food products.

Phenolic Acids and Their Relationship to Nutritional and Technological Grain Parameters of Durum Wheat Under Variable Treatment Intensity in Central European Conditions

The objective of this two-year study was primarily the evaluation of the free and the bound forms of phenolic acids and phenolic aldehydes (PAAs) in grains of four selected cultivars of spring durum wheat subjected to three treatment intensities (GD—Green Deal, BT—Basic and IT—Intensive). All treatments included a common basic level and different spring production levels of nitrogen fertilisation (0 kg N in the case of GD; 30 kg N in the case of BT; and 60 kg N in the case of IT). Pesticide applications included herbicides and insecticides in both the BT and IT treatments, which were supplemented by combinations of fungicide and morphoregulator in the IT treatment. The GD treatment included only basic nitrogen, herbicide protection, and the application of a biostimulator (ExelGrow). The spring durum wheat cultivars subjected to testing were cultivated under Central European conditions, specifically in the Czech Republic’s central Bohemian region. UHPLC-ESI-MS/MS was used for the detection and accurate quantification of PAAs. In parallel, 12 other nutritional and basic technological parameters of the cereal were evaluated. Nine bound and seven free forms of PAAs were quantified in the analysed cereal samples. Bound forms of PAAs were dominant, accounting for 99.4% of total PAAs. Considering single PAAs, ferulic acid was the most abundant, accounting for 87% of the total bound PAAs. Interestingly, year and treatment intensity were the key factors in the variability of both free and bound PAAs, but these factors had different effects on bound PAAs. Under low nitrogen conditions, plants responded with an increase in free PAAs in particular, as well as in three bound PAAs. Unfavourable weather conditions, combined with the presence of biotic factors (e.g., Fusarium infections), significantly influenced the increase in both PAA groups, with the exception of free p-coumaric acid. PCA analysis confirmed close relationships between PAAs within both categories (free and bound). Subsequent correlation analysis further revealed that the immunoreactive gluten component (G12) exhibited a high negative correlation with the dominant ferulic acid (r = −0.70) and sinapic acid (r = −0.68). Additionally, moderate negative correlations were observed between four bound phenolic acids and grain hardness (r = −0.48–−0.60).

The Synergistic Effect of the Same Climatic Factors on Water Use Efficiency Varies between Daily and Monthly Scales

The coupled processes of ecosystem carbon and water cycles are usually evaluated using the water use efficiency (WUE), and improving WUE is crucial for maintaining the sustainability of ecosystems. However, it remains unclear whether the WUE in different ecosystem responds synchronously to the synergistic effect of the same climate factors at daily and monthly scales. Therefore, we employed a machine learning-driven factor analysis method and a geographic detector model, and we quantitatively evaluated the individual effects and the synergistic effect of climate factors on the daily mean water use efficiency (WUED) and monthly mean water use efficiency (WUEM) in different ecosystems in China. Our results showed that (1) among the 10 carbon flux monitoring sites in China, WUED and WUEM exhibited the highest positive correlations with the near-surface air humidity and the highest negative correlation with solar radiation. The correlation between WUEM and climate factors was generally greater than that between WUED and climate factors. (2) There were significant differences in the order of importance and degree of impact of the same climate factors on WUED and WUEM in the different ecosystems. Among the 10 carbon flux monitoring sites in China, the near-surface air humidity imposed the greatest influence on the WUED and WUEM changes, followed by the near-surface water vapor pressure. (3) There were significant differences in the synergistic effects of the same climate factors on WUED and WUEM in the different ecosystems. Among the 10 carbon flux monitoring sites in China, the WUED variability was most sensitive to the synergistic effect of solar radiation and photosynthetically active radiation, while the WUEM variability was most sensitive to the synergistic effect of the near-surface air humidity and soil moisture. The research results indicated that synchronous responses of the WUE in very few ecosystems to the same climate factors and their synergistic effect occurred at daily and monthly scales. This finding enhances the understanding of sustainable water resource use and the impact of climate change on water use efficiency, providing crucial insights for improving climate-adaptive ecosystem management and sustainable water resource utilization across different ecosystems.

6885 Glucose Utilization Differs Between RAS-like and BRAF-like Thyroid Cancer

Abstract Disclosure: S. Kumari: None. E. Chuki: None. J. Klubo-Gwiezdzinska: None. Background: RAS-like thyroid cancer (TC) tends to be more differentiated and less [1][8]Fluorodeoxyglucose Positron Emission Tomography-avid as compared with BRAF-like TC. Therefore, we hypothesized that glucose metabolism may differ between RAS-like and BRAF-like tumors and performed a study aimed at metabolomic profiling of TC. Methods: Based on Institutional Review Board approved protocol, we obtained fresh frozen human TC samples with corresponding normal tissue and performed targeted metabolomics including oxidative phosphorylation (OXPHOS), glycolysis and tricarboxylic acid (TCA) markers using mass spectrometry (MS). The Trusight 500 gene panel was used to determine molecular signature of tumors. Similarly, we performed targeted metabolomics of 4 BRAF-like and 2 RAS-like human TC cell lines. The data were analyzed using Ingenuity Pathway Analysis (Qiagen). We also analyzed mRNA expression of OXPHOS and glycolytic enzymes in 496 human TC tissue samples of The Cancer Genome Atlas (TCGA). The division into BRAF-like and RAS-like TC was based on well-established BRAF-RAS score (BRS) ranging from -1 to +1 for BRAF-like and RAS-like TC, respectively. Results: The study cohort consisted of 20 patients, 13 with BRAF-like and 7 with RAS-like tumors, aged 43±12 years old, 90% (18/20) females, with an average tumor size of 3±1.9 cm, multifocal growth in 55% (11/20) patients, central neck lymph node (LN) metastases in 55% (11/20), lateral neck LN metastases in 15% (3/20) patients and no distant metastases. The tumor size tended to be larger in RAS-like cohort (BRAF-like 2.27±1.28 vs RAS-like 4.34±2.52, p=0.08), and LN metastases more prevalent in BRAF-like cohort (BRAF-like 45% vs RAS-like 10%, p=0.08). Metabolomics data revealed that compared with normal thyroid, human TC tissue samples were characterized by an increased glucose metabolism (p<0.001), TCA (p<0.001) and gluconeogenesis (p<0.001). RAS-like tumors were characterized by a significantly higher TCA (p<0.001) and lower gluconeogenesis (p<0.001) as compared with BRAF-like tumors. Consistently, we found that TCA (p<0.001) and glucose metabolism (p<0.001) was higher in RAS-like vs BRAF-like cell lines. Transcriptomic profiling revealed that RAS-like TC was characterized by an increased expression of majority of tested OXPHOS enzymes compared to BRAF-like tumors, as evidenced by positive correlation with BRS, ranging from r = 0.28 to 0.54, p<0.001. Consistently, BRAF-like TC was associated with an upregulated mRNA expression of anaerobic glycolysis markers, with lactate dehydrogenase A, characterized by the highest negative correlation (r = -0.6, p<0.001) with BRS. Conclusion:RAS-like TC is more likely to utilize glucose through Krebs cycle, while BRAF-like tumors are more prone towards anaerobic glycolysis. Therapeutic strategies based on diverse metabolic profiles may provide a personalized approach to TC therapy. Presentation: 6/3/2024

Effect of the Temperature-Humidity Index on the Productivity of Dairy Cows and the Correlation between the Temperature-Humidity Index and Rumen Temperature Using a Rumen Sensor.

This study was conducted to evaluate the effects of high-temperature stress on dairy cow productivity and the correlation between rumen sensors. The data were collected on the temperature, humidity, milk productivity, milk components, blood components, and rumen sensor data from 125 dairy cows during the experimental period (1 May 2020 to 30 October 2020). High-temperature stress of dairy cows was evaluated based on the temperature-humidity index (THI). The correlations between the high-temperature stress, productivity, and sensor data were analyzed using SAS and R programs. The THI ranged from 46.9 to 81.0 during the experimental period, and a significant decrease was observed in the milk production of dairy cows during August (p < 0.05). Milk production was evaluated to decrease by 1.8% because of high-temperature stress during the experimental period. There was a significantly high negative correlation between the THI ratio of day and rumen temperature (r = 0.744; p < 0.001). The other rumen sensor data did not show a significant correlation with the productivity of dairy cows. The results can be utilized as a guideline for managing temperature and humidity to maintain dairy cow productivity on farms in high-temperature stress conditions.

Breeding a sustainable future for milk production

Selective breeding in livestock has contributed to a remarkable increase in farm productivity and a reduction in carbon footprint in recent decades. This study evaluated selective breeding for more sustainable dairy cows based on both carbon (carbon dioxide equivalent (kg CO2-eq) per cow) and economic (pounds sterling (£) per cow) index values derived for 1042 female dairy cows in the UK that had completed their lifespan. Economic and carbon coefficients were attributed to the genetic background of each animal for a range of commonly directly measured production (milk volume, milk fat yield, milk protein yield) and fitness traits (somatic cell count, fertility and lifespan). A high negative rank correlation was found between the economic and carbon index values among cows (rho = −0.72). Benchmarking cows on a carbon index per cow, along with an economic index, can help to reduce the carbon footprint of milk production.

Heritability and Genetic Correlations of Carcass and Meat Quality Traits in White and Brown Strains of Japanese Quail

Successful breeding programs for Japanese quails rely on accurately estimating genetic parameters linked to economically important traits such as body weight, carcass characteristics, and meat quality. The objective of the present study was to evaluate body weight (BW) characteristics, carcass attributes, and their genetic correlations with select meat quality traits in two strains of Japanese quail (white and brown). A total of 530 quail chicks, with 265 from each strain, were included in the analysis. At six weeks of age, the quails were slaughtered, and carcass traits as well as amino acid profiles were measured. For BW traits, the heritability (h2) estimates ranged from 0.27 at d 1 to 0.36 at d 42. The h2 estimated for carcass traits ranged from 0.19 for liver weight, to 0.42 for carcass yield (CY). The h2 estimated for drip loss (DL) of meat quality was 0.21, and the h2 estimate was 0.35 for the meat's ultimate Ph (Phu). White quail quails recorded the heaviest weight of all carcass traits. Also, white quails had the highest water-holding capacity (WHC), yellowness (b*), and lightness (L*) with the lowest level of DL, cooking losses (CL), and redness (a*) in muscles compared with brown quails. A high genetic correlation of 0.32 was noted between CW carcass weight (CW) and b*. For the pHU, a negative correlation of -0.11 was exhibited with BW. In contrast, L* appeared to have a positive but smaller relationship with CW and CY. High negative correlations were noted for b* with BW and CY -0.24 and -0.27, respectively. The CW showed a moderate relationship (0.19) with CL. In conclusion, the current study revealed that the white quail strain had high BW, as well as the finest carcass traits and meat quality. Therefore, white plumage Japanese quail might be preferred as a meat-producing strain. Keywords: Amino acid, Carcass, Genetic correlation, Meat quality, Heritability, Quail

Mental Accounting Practices and Spending Behavior of Collegiate Students at National University Baliwag: An Assessment

This study assesses the influence of mental accounting practices on the spending behavior of college students at National University Baliwag. It aims to understand how gender and school affiliation influence these connections. The research employs a combination of applied, quantitative, explanatory, and descriptive methods, utilizing data collected through a three-sectioned questionnaire from a sample of 361 students. The findings revealed a high negative correlation between mental accounting practices and spending behavior, stating that students who utilize mental accounting tend to have controlled spending habits. Furthermore, it was noted that gender has no significant difference in mental accounting practices but has a difference in spending behavior. The School of Engineering, Architecture, and Technology (SEAT) showed the highest mental accounting practices, while the School of Tourism and Hospitality Management (STHM) had the highest spending behavior. While several studies have linked mental accounting practices in various shopping methods, this research contributes to the literature by applying the mental accounting theory within a university context in the Philippines. This study is important in understanding behavioral finance, providing guidance and practical implications for the beneficiaries of the study.

Ex-sulfates in the Atmosphere of Barnaul: Assessment and Sources of Еmission

The methodology for calculating the content of ex-sulfates (sulfates of anthropogenic origin) in the ground layer of the atmosphere for the flat territory of the Altai Territory is substantiated. The assessment was made of the content of ex-sulfates in precipitation falling on the territory of the city of Barnaul, as well as the analysis of the percentage of ex-sulfates in the total volume of sulfates in the surface layer of the city’s atmosphere over the past eight years (2014–2022). A correlation analysis of the weighted average seasonal values of ex-SO42– concentration in precipitation and air temperature was carried out. Their high negative correlation in the cold season of the year is shown. It was noted that no significant relationship was found for the warm period, which indicates a direct dependence of the concentration of ex-sulfates on the volume of coal combustion during the heating season.

PSVII-5 Heat shock protein 70 gene expression and association with morphometric and heat tolerance traits in three plumage colors of Noiler chicken exposed to acute heat stress

Abstract Heat stress is one of the most difficult climatic conditions chickens faces and is a direct result of climate change. It is important to research poultry thermotolerance because it may help find genetic lines resistant to heat stress. This study investigated the influence of plumage colors on heat shock protein 70 gene expression in Noiler chickens exposed to acute heat stress. Noiler is a dual-purpose breed developed for smallholder poultry production in Nigeria. A total of 150 birds of three plumage colors (black, brown and white) of mixed sexes were used for the experiment. The birds were raised in deep litter house separated into six groups of 25 birds each and fed with commercial broiler diets from 0-8 wk and broiler finisher diets from 8 to 12 wk old. The birds were shared into treatments in 3 x 2 x 2 factorial arrangements with 3 plumage colors (black, brown, white), two temperature regimens (Control/thermoneutral, Heat stress) and sex of birds (male, female). The heat stressed birds were exposed to 41oC for 8 h from 0600 h to 1400 h for 7 d while control group maintained a thermoneutral temperature range of 30 oC to 32 oC for the same period. At 13 wk old, two birds were selected per treatment, slaughtered and the spleen removed and stored in RNA later for heat shock protein (HSP) 70 gene expression. Data collected were analyzed with Microsoft excel code for fold expression of HSP70 gene while GLM procedure in SAS was used to determine difference in expression of gene. The relative expression of HSP70 brown plumage was greater, upregulated compared with black and white. White plumage birds in control/thermoneutral group were significantly greater in HSP70 expression than other plumage colors and heat stressed birds. Association of HSP70 delta threshold cycle (DCT) values with morphometric and heat tolerance traits were investigated (Figure 1). High negative correlations emerged between HSP70DCT expression and body weight (-0.65), body temperature (-0.73) with moderate positive correlation for rectal temperature (0.55) in black birds (Table 1). HSP70 DCT positively correlated with body weight (0.70), breast/leg circumferences but negatively with wing length, suggesting reduced surface area during heat stress and a supportive role in maintaining protein integrity (Figure 2). For white Noiler birds, HSP70DCT associated negatively with body weight (-0.94) and positively with rectal temperature during heat stress (Table 2). Thermoneutral birds were positively correlated with heat tolerance traits except temperature while heat stressed birds showed low positive correlation with respiratory and pulse rates and very low positive relationship with body and rectal temperatures (Table 4). Sex-based differences emerged, with potential compromise between HSP70-mediated growth/composition in males versus muscle maintenance in females, although leg length/circumference showed shared developmental regulation (Figure 3, Table 3). These findings highlight HSP70’s versatile roles in systemic heat tolerance mechanisms influenced by plumage color, temperature regime and sex.

Characterization of the Ecological Niche and Interspecific Connectivity of Plankton in Baiyangdian Lake by Combining Ecological Networks

To understand the structure of the plankton community and the ecological niche characteristics of their dominant species, sampling surveys of plankton were conducted in Baiyangdian Lake in the spring （March）, summer （July）, and autumn （September） of 2022. The changes in the plankton community during the three seasons were analyzed by constructing ecological network diagrams, non-metric multidimensional scaling analysis （NMDS）, and the ecological niche width. The niche overlap of zooplankton dominant species was evaluated by the improved Levins' formula and Petraitis' index. The interspecific connectivity of dominant species was judged using the chi-square test and interspecies connectivity coefficients. The results showed that the niche width of plankton in the whole area was low. Zooplankton was dominated by rotifers, and phytoplankton was dominated by diatoms, cyanobacteria, and green algae. There were significant seasonal changes in the community structures of plankton. Compared with that in summer and autumn, there were fewer species of plankton in spring and lower interspecies connectivity. The overlap of dominant species of zooplankton was high in summer, and the interspecific competition was intensified, whereas the interspecific overlap of phytoplankton was at a low level in all three seasons. There was a significant positive correlation （W &gt; χ20.05） between phytoplankton in summer and autumn, and the community structure was stable. The interdomain ecological network of zooplankton and phytoplankton showed a high negative correlation ratio in autumn, especially between copepods and cladoceras of zooplankton and chlorophyta and cyanophyta of phytoplankton. The plankton species in Baiyangdian Lake were abundant, with obvious seasonal differences. The dominant species were mainly a narrow ecological niche. The plankton community was generally in a stable state, and there was a strong predation relationship between copepods and cladoceras and green algae and cyanobacteria.

A Mobility Justice Framework to prioritize areas for mobility interventions

Understanding, visualizing, and quantifying how resources are allocated and the fairness of distributions and access is significant for supporting decision-makers in incentivizing development and ensuring that future changes are widely beneficial and fair. By pointing out the need for mobility justice research to shift from state-centric to more society-centric frameworks and metrics, this study proposed a Mobility Justice Framework that integrated two important theories of justice: distribution and recognition justice. The proposed framework highlights the distribution of amenities and burdens in providing transport infrastructure. It also aims to identify those disadvantaged socio-economic groups more exposed to mobility inequalities. To make the framework applicable within the city context and guide decision-making, several metrics (variables) were identified to make principles of distributive and recognition justice operationalizable. Variables such as 1) accessibility by walking, 2) exposure to traffic negative effects, 3) frequency of use of transport modes, and 4) availability of transport infrastructure were used to identify neighborhoods and the different types of mobility resources/burdens that disadvantaged socio-economic groups are exposed to. To showcase its usability, the framework and methodology have been applied to the city of Munich to highlight neighborhoods with a higher proportion of older people and the transport disadvantages associated with these target groups. A higher negative correlation between older people and mobility resources/burdens can be observed for the following variables: accessibility by walking to activities, availability of walking and cycling infrastructure, and availability of car-sharing services. When measured against exposure to negative transport effects, a higher positive correlation was observed. The paper ends with a discussion section on the relevance and usability of the proposed framework for transport planning and policy and its limitations.

Computer-Assisted Algorithm for Quantification of Fibrosis by Native Cardiac CT: A Pilot Study.

Background/Objectives: Recent advances in artificial intelligence, particularly in cardiac imaging, can potentially enhance patients' diagnosis and prognosis and identify novel imaging markers. We propose an automated, computer-aided algorithm utilizing native cardiac computed tomography (CT) imaging to identify myocardial fibrosis. This study aims to evaluate its performance compared to CMR markers of fibrosis in a cohort of patients diagnosed with breast cancer. Methods: The study included patients diagnosed with early HER2+ breast cancer, who presented LV dysfunction (LVEF < 50%) and myocardial fibrosis detected on CMR at the time of diagnosis. The patients were also evaluated by cardiac CT, and the extracted images were processed for the implementation of the automatic, computer-assisted algorithm, which marked as fibrosis every pixel that fell within the range of 60-90 HU. The percentage of pixels with fibrosis was subsequently compared with CMR parameters. Results: A total of eight patients (n = 8) were included in the study. High positive correlations between the algorithm's result and the ECV fraction (r = 0.59, p = 0.126) and native T1 (r = 0.6, p = 0.112) were observed, and a very high positive correlation with LGE of the LV(g) and the LV-LGE/LV mass percentage (r = 0.77, p = 0.025; r = 0.81, p = 0.015). A very high negative correlation was found with GLS (r = -0.77, p = 0.026). The algorithm presented an intraclass correlation coefficient of 1 (95% CI 0.99-1), p < 0.001. Conclusions: The present pilot study proposes a novel promising imaging marker for myocardial fibrosis, generated by an automatic algorithm based on native cardiac CT images.

Экспериментальное исследование рабочей памяти и внимания подростков с разной степенью вовлеченности в виртуальную деятельность в период пандемии КОВИД-19

&lt;p&gt;The study of working memory and attention of adolescents aged 16-17 years was conducted during the COVID-19 pandemic, which caused additional stress due to forced isolation and reduced social contacts. The decrease in opportunities to communicate with peers was reflected in increased communication on social networks and the use of online games on the Internet, which fully corresponds to the information known in the literature. The study of working memory and attention was conducted in a group of high school students (43 people), with satisfactory and good academic performance, who had previously participated in a questionnaire to assess the characteristics of behavior in an Intern. Cognitive processes were evaluated in a computer program simulating gaming activity using a dynamic digital matrix. Students had to quickly search for numbers of different sizes located in cells, the color of which changed after each search action. The program recorded two types of errors due to choosing the wrong number when forgetting the previous choice and due to choosing the wrong number in a cell with a reduced quality of conscious attention, as well as the reaction time to the correct choice, the time of erroneous actions and the total time of the test. The task turned out to be very difficult for teenagers, as not everyone successfully coped with it the first time. The average group search time for digits is 10 seconds with the number of errors in the search equal to 50, that is, exceeding the number of changes in the matrix. Factor analysis allowed us to establish a high negative correlation of the poor quality of the task in the dynamic matrix with the time spent daily with gadgets in a virtual environment. Closer links between digital leisure time and the number of errors were found for the characteristics of working memory than for arbitrary attention.&lt;/p&gt;

The Relationship Between Intramural Fat Accumulation and Sarcopenia on MR Enterography Exams in Patients with Crohn's Disease.

Research on magnetic resonance enterography (MRE) and sarcopenia for assessing Crohn's disease (CD) is growing. Our study examined the connections between the presence of sarcopenia, intramural fat accumulation (IFA), and clinical, laboratory, and MRE findings.This retrospective study was conducted on 112 patients with suspected or diagnosed CD who underwent 3-tesla MRE. The study examined the correlation between sarcopenia-related parameters and MRE findings. Results of MRE exams and clinical and laboratory results were statistically analyzed. The Kruskal-Wallis, Pearson chi-square, and Fisher-Freeman-Halton tests were used for comparison.It was determined that patients with active inflammation on a chronic basis had more IFA than the others (p<0.001). There were positive relationships between IFA and intramural edema (p<0.001). There were positive correlations between IFA and high b-values and negative correlations with apparent diffusion coefficient values (p<0.05). Positively significant relationships were found between IFA and wall thickness, affected segment length, disease duration, and sedimentation values (p<0.05). Strong correlations were found between sarcopenia and the CD activity index as well as wall thickness (p<0.001/p=0.003). There was no significant relationship between steroid usage and other variables.The presence of IFA is associated with chronic inflammation. There was no clear relationship between steroid use and IFA. Our findings support the idea that sarcopenia is related to the activity of CD. Further comprehensive research is required on these subjects. · The usage of MR enterography for the management of CD is increasing day by day due to its advantages.. · There is a paucity of evidence regarding the relationship between sarcopenia and MR enterography findings in patients with CD.. · Intramural fat accumulation (IFA) is a sign of chronicity in patients with CD.. · The presence of IFA seems to be associated with active inflammation on a chronic basis.. · There was no clear relationship between steroid use and IFA.. · Algin O, Güneş YC, Cankurtaran RE et al.

Characterizing the Regional Differences in Carbon Dioxide Concentration Based on Satellite Observations in the Beijing-Tianjin-Hebei Region during 2015–2021

The regional differences in carbon dioxide (CO2) variations from the Orbiting Carbon Observatory-2 (OCO-2) over the Beijing-Tianjin-Hebei (Jing-Jin-Ji) region from 2015 to 2021 are analyzed in this study. This study shows an annual increase and a seasonal cycle; the CO2 annual growth rate was about 2.63 ppm year−1, with the highest value being in spring and the lowest in summer. The spatial distribution is unbalanced, regional differences are prominent, and the CO2 concentration is lower in the north of the Jing-Jin-Ji region (like Zhangjiakou, Chengde, and Qinhuangdao). Land-type structures and population economy distributions are the key factors affecting CO2 concentration. By analyzing the land-type structures over Jing-Jin-Ji in 2020, we find that cropland, woodland, and grassland (CWG) are the main land cover types in Jing-Jin-Ji; the proportion of these three types is about 83.3%. The woodland areas in Zhangjiakou, Chengde, and Qinhuangdao account for about 65% of the total woodland areas in Jing-Jin-Ji; meanwhile, the grassland areas in these three regions account for 62% of the total grassland areas in Jing-Jin-Ji. CO2 concentration variation shows a high negative correlation with CWG land areas (coefficient of determination (R2) &gt; 0.76). The regions with lower population and GDP secondary industry (SI) density also have lower CO2 concentration (like Zhangjiakou, Chengde, and Qinhuangdao), and the regions with higher population and GDP SI density also have higher CO2 concentration (like the southeast of Jing-Jin-Jin).

Studies on Benthic Fauna with relation to physio chemical parameters in Betana Wetland, Morang, Nepal

This study examined the benthic fauna and its relation to the physic chemical parameters in Betana wetland, Morang, Nepal from December 2020 to May 2021. Over the course of six months, the study found two genera of Annelida (Hirudinea and Lumbricina), eight genera of Arthropoda (Macrobranchium, Chironomus, Cyclops, Cypridopsis, Blasturus, Diptera, Coeleptera, and Naupli), and four species of Mollusca (Bellamya bengalensis, Parreysia flavidens, Lamellidens marginalis, and Indoplanorbis exutus). Arthropods were more prevalent in the spring due to the increase in temperature. The average maximum water temperature was 23.66°C in the spring and the minimum was 20.25°C in the winter. The maximum soil temperature was 24.9°C in the spring and the minimum was 21.08°C in the winter. The pH was highest in the spring (7.67) and lowest in the winter (7.21). The highest dissolved oxygen (DO) was found in the winter (7.6 mg/l) and the lowest was in the spring (7 mg/l). The maximum free CO₂ was found in the spring (26.83 mg/l) and the minimum was in the winter (21.25 mg/l). Total alkalinity was highest in the spring (113 mg/l) and lowest in the winter (105 mg/l). Total hardness was highest in the spring (83.51 mg/l) and lowest in the winter (69.25 mg/l). Water temperature and soil temperature had a high correlation coefficient (0.93) with benthic fauna, while DO and pH showed a high negative correlation coefficient (-0.93 and -0.92), respectively.

Investigation on the contaminate of hand washing activities on the surface of environmental objects in intensive care unit

To detect the contaminate of faucets in hospitals and the splash during hand washing, and to explore the reasonable layout of hand washing pools. Two faucets with roughly the same spatial layout in the ICU of a third-class first-class general hospital were selected, and the farthest splashing distance and specific splashing points were measured by color paper. Samples were detected by ATP detection technology and routine microbial detection method, and the contaminate of faucets was analyzed. After 72 h of daily hand-washing activities, the furthest distance to the splash point was about 100 cm around the faucet, and the place 40–110 cm around the faucet was contaminated seriously. The farthest distance that the splash point reached was about 80 cm around the faucet with the center of the circle, and the area 40–60 cm around the faucet was heavily contaminated. The distance from the water outlet of the long handle and the short handle faucet to the detection point had a high negative correlation (r = − 0.811, P < 0.001) and a moderate negative correlation (r = − 0.475, P = 0.001) with the number of splash points, respectively. The qualified rates of ATP detection and microbial culture were 25% and 15%, respectively. Pseudomonas aeruginosa, Staphylococcus epidermidis, and other pathogenic bacteria were detected in the water outlet of the faucet and the surrounding environment. Safe hand hygiene facilities are one of the important guarantees of hand hygiene effect. Clean objects and objects related to patients should not be placed within 1 m range near the water outlet of faucet. Anti-splash baffle should be installed as much as possible when conditions permit to reduce the contaminate caused by splash during hand washing.

Exploring the Influence of Soil Types on the Mineral Profile of Honey: Implications for Geographical Origin Prediction.

Honey contains a wide range of inorganic substances. Their content can be influenced, i.e., by the type of soil on which the bee pasture is located. As part of this study, the mineral profile of 32 samples of honey from hobby beekeepers from the Czech Republic wasevaluated and then compared with soil types in the vicinity of the beehive location. Pearson's correlation coefficient was used to express the relationship between mineral substances and soil type. There was a high correlation between antroposol and Zn (R = 0.98), Pb (R = 0.96), then between ranker and Mn (0.95), then regosol and Al (R = 0.97) (p < 0.05). A high negative correlation was found between regosol and Mg (R = -0.97), Cr (R = -0.98) and between redzinas and Al (R = -0.97) (p < 0.05). Both positive and negative high correlations were confirmed for phaeozem. The CART method subsequently proved that the characteristic elements for individual soil types are B, Ca, Mg, Ni, and Mn. The soil types of cambisol, fluvisol, gleysol, anthrosol, and kastanozem had the closest relationship with the elements mentioned, and it can therefore be assumed that their occurrence indicates the presence of these soil types within the range of beehive location.

Sociodemographic Inequalities in COVID-19 Booster Dose Vaccination Coverage: a Retrospective Study of 196 Provinces in Peru.

The COVID-19 vaccination coverage shows variability in booster doses between residency areas or ethnicity. The aim of this study was to evaluate how sociodemographic conditions influence unequal vaccination coverage with booster doses against COVID-19 in Peru. A retrospective, ecological study with an evaluation of 196 provinces in Peru. The sociodemographic conditions were evaluated as sources of inequality (sex, age group, educational level, residence area, and ethnic group). The inequality measure used was the GINI, an index that show the inequal vaccination coverage with third and fourth booster doses against COVID-19 in Peruvians provinces. The index allow determinate a higher inequality when the value is near to 1, and a lower inequality when the value is near to 0. Also, the impact of each sociodemographic condition in the general inequality was evaluate with a decomposition analysis of GINI coefficient into Sk (composition effect), Gk (redistribution effect), Rk (differential effect). In provinces evaluated the mean vaccine coverage for the third and fourth booster doses was 57.00% and 22.19%, respectively at twelve months since the beginning of vaccination campaign. The GINI coefficient was 0.33 and 0.31, for the third and fourth booster doses coverage, respectively. In the decomposition analysis, twelve months after the start of the third and fourth dose vaccination campaign, revealed higher Sk values for people living in rural areas (Sk = 0.94 vs. Sk = 2.39, respectively for third and fourth dose), while higher Gk values for Aymara (Gk = 0.92 vs. Gk = 0.92, respectively), Quechua (Gk = 0.53 vs. Gk = 0.53, respectively), and Afro-Peruvians (Gk = 0.61 vs. Gk = 0.61, respectively). Also, higher negative correlation in Rk values for people with elementary education (Rk=-0.43 vs. Rk=-0.33, respectively), aged between 15 and 19 years (Rk=-0.49 vs. Rk=-0.37, respectively), and Aymara (Rk=-0.51 vs. Rk=-0.66, respectively). The rural residency area, lower education and Quechua, Aymara or Afro-Peruvians ethnicity determinated inequalities in vaccination coverage with booster doses against COVID-19 in Peruvian provinces.
