Storage Conditions and Adsorption Thermodynamic Properties for Purple Corn

Adsorption isotherms provide insight into the thermodynamic properties governed by food storage conditions. Adsorption isotherms of purple corn of the Canteño variety were evaluated at 18, 25, and 30 °C, for the equilibrium relative humidity (ERH) range between 0.065 and 0.95. The equilibrium moisture (Xe) was determined by the continuous weight-change method. Seven mathematical models of isotherms were modeled, using the coefficient of determination R2, mean absolute error (MAE), and estimated standard error (ESE) as the convergence criterion. Thermodynamic parameters such as isosteric heat (qst), Gibbs Free Energy (ΔG), differential entropy (ΔS), activation energy (Ea), and compliance with the isokinetic law were evaluated. It was observed that the adsorption isotherms presented cross-linking around 75% ERH and 17% Xe, suggesting adequate storage conditions at these values. The GAB and Halsey models reported better fit (R2 > 97%, MAE < 10%, ESE < 0.014 and random residual dispersion). The reduction of Xe from 17 to 7%, increases qst, from 7.7022 to 0.0165 kJ/g, while ΔG decreases considerably with the increase in Xe, presenting non-spontaneous endergonic behavior, and linear relationship with ΔS, evidencing compliance with the isokinetic theory, governed by qst. Ea showed that more energy is required to remove water molecules from the upper layers bound to the monolayer, evaluated using CGAB. The models predicted the storage conditions, and the thermodynamic parameters show the structural stability of the purple corn grains of the Canteño variety during storage.
Antibacterial Properties of Non-Modified Wool, Determined and Discussed in Relation to ISO 20645:2004 Standard

Wool is considered to possibly exhibit antibacterial properties due to the ability of wool clothing to reduce the build-up of odor, which arises from the microbial activity of skin microbiota. Indeed, when tested with a widely used agar diffusion plate test method, even wool or other textiles not treated with any antimicrobial agent can be interpreted to show certain antibacterial effects due to the lack of growth under the specimen, as instructed in ISO 20645:2004 standard. Therefore, we analyzed in detail what happens to bacterial cells in contact with untreated wool and cotton fabric placed on inoculated agar plates by counting viable cells attached to the specimens after 1 and 24 h of contact. All wool and several cotton samples showed no growth under the specimen. Nevertheless, it was shown without a doubt that neither textile material kills bacteria or inhibits cell multiplication. A reasonable explanation is that bacterial cells firmly attach to wool fibers forming a biofilm during multiplication. When the specimen was lifted off the nutrient agar surface, the cells in the form of biofilm remained attached to the wool fibers, removing the biomass and resulting in a clear, no growth zone underneath it. By imaging the textile specimens with X-ray microtomography, we concluded that the degree of attachment could be dependent on surface topography. The results indicate that certain textiles, in this case, wool, could exhibit antibacterial properties by removing excess bacteria that grow on the textile/skin interface when taken off the body.
Adaptive Multi-Lane Detection Based on Robust Instance Segmentation for Intelligent Vehicles

Recent advances in lane detection based on deep neural networks have enhanced the detection performance of intelligent vehicles under different traffic scenes. However, it’s still difficult for existing lane detection algorithms to robustly extract lane instances and adapt to varying lane numbers simultaneously. In this paper, we focus on anchor-free methods and propose an adaptive multi-lane detection approach based on instance segmentation for intelligent vehicles. By combining instance segmentation with lane center estimation, the proposed approach achieves robust and efficient performance. Besides, cosine-metric is incorporated into the objective functions that enables the proposed method to extract more discriminative features for foreground extraction. Different from the proposed approach, most existing algorithms treat the lane instance detection task as a multi-class object detection problem which require to predefine different lane categories and fix the lane number in advance, while the lane category predefinition degrades the robustness of the algorithms. Experimental results on public datasets demonstrate that the proposed approach achieves better overall performance compared with the state-of-the-art anchor-free lane detection methods. It is also illustrated that the proposed approach can be easily extended to other instance segmentation tasks, e.g. vehicle segmentation.
Recent Advancements in the Treatment of Rectal Gastrointestinal Stromal Tumor: In Era of Imatinib

Abstract Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumor of the gastrointestinal tract, with an annual incidence of 10–15 cases per million. However, rectal GIST has a low incidence, accounting for approximately 0.1% of all rectal tumors. The treatment of rectal GISTs is still controversial and the relative unified guidelines and consensus opinions are inadequate. Treatment is based primarily on the clinical experience of the physician. The widespread application of neoadjuvant imatinib therapy allows diversification of treatment, especially in the choice of surgical methods. Herein, we reviewed the most recent literature and summarized the new progress in rectal tumor treatment, with the aim of providing patients with more systematic and individualized therapeutic strategies.
Prevalence of Adverse Childhood Experiences in Students with Emotional and Behavioral Disorders in Special Education Schools from a Multi-Informant Perspective

Adverse childhood experiences (ACEs) are associated with an increased risk of developing severe emotional and behavioral problems; however, little research is published on ACEs for students with emotional and behavioral disorders (EBD) in special education (SE) schools. We therefore systematically explored the prevalence, type and timing of ACEs in these students from five urban SE schools in the Netherlands (Mage = 11.58 years; 85.1% boys) from a multi-informant perspective, using students’ self-reports (n = 169), parent reports (n = 95) and school files (n = 172). Almost all students experienced at least one ACE (96.4% self-reports, 89.5% parent reports, 95.4% school files), and more than half experienced four or more ACEs (74.5% self-reports, 62.7% parent reports, 59.9% school files). A large majority of students experienced maltreatment, which often co-occurred with household challenges and community stressors. Additionally, 45.9% of the students experienced their first ACE before the age of 4. Students with EBD in SE who live in poverty or in single-parent households were more likely to report multiple ACEs. Knowledge of the prevalence of ACEs may help understand the severe problems and poor long-term outcomes of students with EBD in SE.
Dynamics and Near‐Field Surface Motions of Transitioned Supershear Laboratory Earthquakes in Thrust Faults

We study how the asymmetric geometry of thrust faults affects the dynamics of supershear ruptures and their associated trailing Rayleigh ruptures as they interact with the free surface, and investigate the resulting near‐field ground motions. Earthquakes are mimicked by propagating laboratory ruptures along a frictional interface with a 61° dip angle. Using an experimental technique that combines ultrahigh‐speed photography with digital image correlation, we produce sequences of full‐field evolving measurements of particle displacements and velocities. Our full‐field measurement capability allows us to confirm and quantify the asymmetry between the experimental motions of the hanging and footwalls, with larger velocity magnitudes occurring at the hanging wall. Interestingly, because the motion of the hanging wall is generally near‐vertical, while that of the footwall is at dip direction shallower than the dip angle of the fault, the horizontal surface velocity components are found to be larger at the footwall than at the hanging wall. The attenuation in surface velocity with distance from the fault trace is generally larger at the hanging wall than at the footwall and it is more pronounced in the vertical component than in the horizontal one. Measurements of the rotations in surface motions confirm experimentally that the interaction of the rupture with the free surface can be interpreted through a torqueing mechanism that leads to reduction in normal stress near the free surface for thrust earthquakes. Nondimensional analysis shows that the experimental measurements are consistent with larger‐scale numerical simulations as well as field observations from thrust earthquakes.
Sexual and Gender Oppression Situations at Iranian Universities

Article history: Received date: 2021/01/17 Review date: 2021/07/20 Accepted date: 2021/07/27 Abstract Purpose: The present article aims to study the gender oppression of female students in the context of the existing relations at Iranian universities. Methodology: To this end, based on the qualitative method, ten universities in different fields were selected and in-depth interviews were conducted with 146 female students who experienced sexual harassment by male professors. Thus, we analysed interviews by thematic analysis. Findings: University community is the only mixed community, gender-wise, in Iranian administrative-governmental settings, with a very different cultural diversity and circulation. Therefore, scores of situations, in which gender and sexual encounters are possible, arise amid everyday university relationships. Although the issue of male professors’ sexual and gender encounters with female students has been publicized in Iran, it has been mostly ignored in research studies. Conclusion: The findings of the study show that when the Islamic cultural principle of gender relationship boundaries is regarded firmly or violated by male professors, the triad of ‘violence’, ‘discrimination’ and ‘exploitation’ will emerge, resulting in gender oppression toward female students.
Uncovering the Mechanism of the Hydrogen Poisoning on Ru Nanoparticles via Density Functional Theory Calculations

Although hydrogen plays a crucial role in ammonia synthesis, very little is known about its poisoning of Ru catalysts. In this study, density functional theory calculations of H2 and N2 dissociations, and H atom binding on Ru153 were performed to provide a fundamental understanding of hydrogen poisoning. Because of the kinetic dominance of the H2 dissociation over N2 (vertically or horizontally adsorbed) splitting, the dissociated H atoms block the active sites required for horizontal (less energetically demanding dissociation) N2 adsorption to occur either from the gas phase or after its geometrical transformation from being adsorbed vertically. Additionally, the dissociated H atoms withdraw electrons from the surface, which reduces the ability of the neighboring Ru atoms to donate electrons for N2 activation, hindering its dissociation and suppressing ammonia synthesis.
The role of methylenetetrahydrofolate reductase C677T gene polymorphism as a risk factor for coronary artery disease: a cross-sectional study in the Sidoarjo Regional General Hospital

Introduction hyperhomocysteinemia (HHcy) may contribute to an increased risk of coronary artery disease (CAD). The underlying mechanisms are not well understood, but other than dietary intake factors, hyperhomocysteinemia may genetically result from a methylenetetrahydrofolate reductase (MTHFR) C677T gene polymorphism. A cross-sectional study was performed to assess whether this mutation was a potential genetic risk factor for CAD. Methods this cross-sectional study was performed on 30 CAD patients and 30 normal healthy controls at Sidoarjo Regional General Hospital. The polymorphisms of the MTHFR C677T gene was assessed by polymerase chain reaction (PCR), and plasma homocysteine was measured by chemiluminescence immunoassay (CLIA) and then compared between CAD patients and control subjects by the multivariate logistical regression model. Results results from an independent sample t-test analysis showed that plasma homocysteine concentrations were significantly higher in CAD patients compared to the control group individuals (13.91 ± 4.55 μmol/L vs 10.97 ± 3.45 μmol/L; p<0.05). There were no significant correlations between MTHFR C677T gene polymorphism and other risk factors, such as age at diagnosis with acute coronary syndrome, sex, smoking, lipid profile, diabetes, hypertension, C-reactive protein (CRP), creatinine, and homocysteine (p>0.05). In multivariate analysis models, the C677T genotype frequencies were insignificantly different between CAD patients and control subjects (p>0.05). Meanwhile, the results of adjusted odds ratio (aOR), 95% confidence interval (CI), and p-value for homocysteine, age, and smoking were aOR: 1.264, 95% CI : 1.042-1.535, p = 0.018; aOR: 0.916, 95% CI: 0.842-0.997, p = 0.043, and aOR: 5.428, 95% CI 1.532-19.226, p = 0.009, respectively. Homocysteine, age, and smoking were significantly different between CAD patients and control subjects (p<0.05). Conclusion hyperhomocysteinemiais significantly correlated with an increased risk of CAD, but MTHFR C677T gene polymorphism might not contribute to increased CAD risk.

The present experiment was carried out during Kharif, 2019 at Jawaharlal Nehru krishi Vishwavidyalaya, Jabalpur, Madhya Pradesh, India. A total of 500 accessions were evaluated and observations were recorded on twelve traits viz., days to flower initiation, days to fifty percent flowering, days to maturity, plant height (cm), number of primary branches per plant, number of secondary branches per plant, number of capsules per plant, number of seeds per capsule, capsule length (cm), 1000 seed weight (g), seed yield per plant (g) and oil content (%). REML analysis revealed significant differences among the 500 accessions for all the traits. It indicates an adequate amount of genetic variability present among the accessions for yield and yield attributing traits. Phenotypic coefficients variation values were higher than Genotypic coefficients variation values under the study. High heritability was recorded for all the traits under experiment. Genetic advance as percentage of mean recorded low for traits days to flower initiation, days to 50% flowering, days to maturity. Medium for traits oil content (%), plant height, number of seeds per capsule, whereas traits capsule length, number of capsule per plant, thousand seed weight, number of primary branches per plant, seed yield per plant, number of secondary branches per plant recorded in high magnitudes. This result indicates preponderance of additive gene effect, which will help to make selection in early segregating generation.

In the sampling plan, we developed experimental designs for evaluating the passage of juvenile salmonids through the bypass system including the evaluation at design flow of injury and mortality rates, and passage of juvenile salmonids through and over the screens. We designed and fabricated fish nets for screen leakage tests, and holding facilities for test fish. Modifications to improve evaluation activities were incorporated into the collection facility, and our sampling gear. We designed and fabricated collection systems for the juvenile fish bypass facilities at Maxwell and Westland diversion dams. Preliminary monitoring of system operation was performed at Westland Diversion Dam. We offer recommendations for improving preparations and designs of future evaluations, and also recommend that a detailed evaluation of the Maxwell and Westland juvenilemore » facilities, including evaluation of fish condition and fish passage through or over the screens, be conducted. « less
The effects of the oral administration of graphene oxide on the gut microbiota and ultrastructure of the colon of mice

Background Graphene oxide (GO) has been widely used in the field of biomedicine and has shown great potential in drug delivery. Oral administration is an important mode of administration, but there are few studies on the effects of oral GO on gastrointestinal tract and gut microbiota. This study sought to explore the effects of oral GO on the gastrointestinal tract and gut microbiota. Methods In total, 20 C57BL/6 male mice, aged 5 weeks old, were randomly divided into the following 4 groups (n=5): the control group, the GO30 group, the GO60 group, and the GO120 group. The GO sample solution was administered intragastrically at the doses of 30, 60, or 120 mg/kg every 3 days, and the control group was given an equal volume of distilled water. On the 16th day, mouse feces were taken for 16S ribosomal ribonucleic acid (rRNA) sequencing analysis, and the mice were dissected, and the heart, liver, kidney, and colon removed for histological analysis. Additionally, the ultrastructure of the colon was observed by transmission electron microscopy. Results No obvious damage was observed in the hearts, livers, and kidneys of the mice. However, the intestinal ultrastructure of the mice in the GO group was damaged. The main manifestations were an uneven arrangement and local atrophy of the microvilli, swelling of the mitochondria and endoplasmic reticulum, and the widening of the intercellular spaces. The damage was positively correlated with increasing GO doses. The 16S rRNA sequencing results showed that the structure of the gut microbiota in the GO group was altered, and the contents of Alistipes, Enterobacteriaceae, Eubacterium, and Xanthobacteraceae were decreased. Conclusions The oral administration of GO had no obvious toxicity effects on the hearts, livers, and kidneys of the mice. However, it did destroy the ultrastructure of the mouse colon and shift the structure of the gut microbiota, decreasing the contents of Alistipes, Enterobacteriaceae, Eubacterium, and Xanthobacteraceae.
miR-143-5p suppresses breast cancer progression by targeting the HIF-1α-related GLUT1 pathway

Breast cancer (BC) is a commonly identified life-threatening type of cancer and a major cause of death among women worldwide. Several microRNAs (miRs), including miR-143-5p, have been reported to be vital for regulating hallmarks of cancer; however, the effect of miR-143-5p on BC requires further exploration. The present study performed bioinformatics analysis on GSE42072 and GSE41922 datasets from the National Center for Biotechnology Information Gene Expression Omnibus (GEO) database to identify miR-143-5p expression patterns. Furthermore, miR-143-5p expression was detected in BC cell lines and tissues via reverse transcription-quantitative PCR. Post-transfection with miR-143-5p mimics, Cell Counting Kit-8, colony formation and Transwell assays were performed to explore the effects of miR-143-5p on BC cell proliferation, colony formation, and migration. The association of miR-143-5p with the hypoxia-inducible factor-1α (HIF-1α)-associated glucose transporter 1 (GLUT1) pathway was explored via western blotting, immunofluorescence and dual-luciferase reporter assay. The present study detected high expression of miR-143-5p in BC tissue of the GSE42072 and serum of the GSE41922 datasets by GEO chip analysis. Additionally, the expression levels of miR-143-5p were decreased in BC tissues compared with those in adjacent healthy tissues, and low miR-143-5p expression was associated with a poorer prognosis and shorter survival time in patients with BC. In vitro, miR-143-5p expression levels were decreased in BC cells, and transfection with miR-143-5p mimics suppressed BC cell proliferation, colony formation, migration. Furthermore, miR-143-5p targeted the HIF-1α-related GLUT1 pathway, and inhibited HIF-1α and GLUT1 expression. Additionally, HIF-1α agonists reversed the miR-143-5p-induced inhibition during tumorigenesis. In conclusion, miR-143-5p exhibited low expression in BC tissues, and suppressed BC cell proliferation, colony formation, migration. Moreover, the antitumor effects of miR-143-5p targeted the HIF-1α-related GLUT1 pathway.
Variation in some Haematological Parameters in Patients with Plasmodiasis Attending Antenatal Clinic in Primary Health Care Centre, Ozuoba, Port Harcourt

Introdction: Haematological parameters are useful in making diagnosis of diseases and also help in the antenatal assessment of women during pregnancy. The physiological changes of pregnancy, due to the influence of hormones such as oestrogen, progesterone also affect haematological indices when compared with the non-pregnant state. Aim: The study investigated haematological indices in pregnant women with plasmodiasis attending antenatal clinics in Primary health care centre Ozuoba, Port Harcourt. Methodology: This was a cross sectional study, which recruited a total of one hundred (100) subjects, of which (40) were non parasitized pregnant women who served as control, while (60) were parasitized pregnant women who served as test. The samples were analyzed for haematological parameters using (Sysmex XP-300), while microscopy was used to investigated for the presence of malaria parasite. Result: Comparing the hematological parameters of the study population at different level of plasmodiasis, showed that WBC, and Neutrophil were significant with p-Value of 0.001 and 0.0089 respectively at P<0.05. The other haematological parameters such as, Red Blood Cell, Haemoglobin, Haematocrit, Mean Cell Volume, Mean Cell Haemoglobin, Mean CellHaemoglobin Concentration, Platelet, Plateletcrit, Neutrophils, lymphocyte, monocyte, eosinophil and basophil showed no statistical significant difference at p<0.05. While comparison of the haematological parameters of the study group according to parity showed that WBC count had statistical significance with a p-Value of 0.0035 at p<0.05. Conclusion: Findings from this study has shown that there was statistical significant difference in the white blood cell count of malaria-parasitized pregnant subject. It was further revealed that there was no statistical significant difference in the other haematological parameters. The reason for the pattern of result obtained is that some of the pregnant women may have been receiving prophylactic antimalarial drugs before their recruitment, this will in turn minimize the impact of malaria infection on some haematological parameters.
