Authors: Shacham Maayan , Greenblatt-Kimron Lee , Hamama-Raz Yaira , Mijiritsky Eitan , Ben-Ezra Menachem , Humphris Gerry
Published: April 2022

Background: Increased demands for invasive and non-invasive treatments related to body image disturbances are seen worldwide. These demands may be related to body image dissatisfaction. No study to date investigated the relationship between body image dissatisfaction and dental anxiety (namely, anticipatory dental anxiety and treatment dental anxiety) among a non-clinical population. The current study aims to unveil such relationships. Methods: Dentally anxious people may choose to ‘cope’ with their anxiety via unnecessary invasive procedures related to their body image dissatisfaction. In the current study, 553 individuals completed an online survey assessing their dental anxiety, dental neglect, and body image via self-report questionnaires. Results: Body image dissatisfaction was significantly correlated with dental anxiety. In contrast to previous studies, dental neglect was negatively associated with dental anxiety. Additionally, no link was found between body image dissatisfaction and dental neglect. Conclusions: The current study highlights the importance of addressing these factors prior to invasive procedures.
An Experimental Investigation into the Thermal Characteristics of Bump Foil Journal Bearings
Authors: Zhou Yu , Shao Longtao , Zhao Shuai , Zhu Kun , Ding Shuiting , Du Farong , Xu Zheng
Published: April 2022

Bump foil journal bearings (BFJBs) are widely used in the superchargers of aviation piston engines (APEs). This paper proposes a method to evaluate the operating state of superchargers by monitoring the bearing temperature. A numerical model with a repeating symmetrical structure in the axial direction is established based on a certain type of supercharger, which solves the temperature field of BFJBs with the non-isothermal Reynolds equation and energy equation. It can be used to analyze the effect of thermal expansion on lift-off speed and stop-contact speed. A new test rig and six various BFJBs were designed to check the temperature characteristics of the BFJBs with variable load and speed. By comparing the numerical results with the experimental results, it was shown that the air film temperature increased almost linearly with the increase in bearing load and speed. However, the temperature increase caused by the rotation speed was significantly greater than the load. The structural parameters of the BFJB affected the bearing support stiffness, which had a nonlinear effect on the lift-off speed and air film temperature. Therefore, the proposed method to evaluate the state of superchargers with BFJBs was effective. These thermal characteristics can be used to guide BFJB design and predict the life cycle of BFJBs.

We examined children in Da Nang, a dioxin contamination hotspot in Vietnam, twice at 5 and 8 years of age, and investigated sex- and age-dependent differences in the effects of dioxin exposure on attention deficit hyperactivity disorder (ADHD) symptoms. We also studied autistic traits in children with ADHD symptoms. A total of 163 children participated in follow-up surveys at 5 and 8 years of age and were included in the present analysis. ADHD symptoms were assessed using an ADHD rating scale with inattention and hyperactivity-and-impulsivity (hyperactivity) subscales. Autistic behaviors were evaluated using the Autism Spectrum Rating Scale (ASRS). Perinatal dioxin exposure was indicated by dioxin levels in maternal breast milk. In boys, hyperactivity scores were significantly higher in the high 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) group only at 5 years of age. In girls, hyperactivity scores at 8 years of age were significantly higher in the high TCDD group, which was significantly associated with those at 5 years of age. In girls, ASRS unusual behavior scores were significantly higher with higher TCDD exposure and hyperactivity scores at 8 years of age. These results suggest that high perinatal TCDD exposure may increase ADHD likelihood and autistic traits, particularly in girls of 7–8 years of age.

Published: April 2022

Veterinary antibiotics (VAs) released into the environment are a concern because of the possibility for increasing antibiotic-resistance genes. The concentrations of six VAs, chlortetracycline, oxytetracycline, tetracycline, sulfamethazine, sulfamethoxazole, and sulfathiazole, in manure-based compost, soil, and crops were measured using liquid chromatography–tandem mass spectrometry. Mass balance analysis was conducted based on the measured antibiotic concentration, cultivation area, and amount of manure-based compost applied. The result showed that the detected mean concentration of VAs ranges was 3.52~234.19 μg/kg, 0.52~13.08 μg/kg, and 1.05~39.57 μg/kg in manure-based compost, soil, and crops, respectively, and the substance of VAs detected in different media was also varied. Mass balance analysis showed that the VAs released from the manure-based compost can remain in soil (at rates of 26% to 100%), be taken up by crops (at rates of 0.4% to 3.7%), or dissipated (at rates of 9% to 73%) during the cultivation period. Among the six VAs, chlortetracycline and oxytetracycline mainly remained in the soil, whereas sulfamethoxazole and sulfathiazole were mainly dissipated. Although we did not verify the exact mechanism of the fate and distribution of VAs in this study, our results showed that these can vary depending on the different characteristics of VAs and the soil properties.

Published: April 2022

Atmospheric particulate matter (PM) was measured continuously at an urban site in Baoji city in northern China in 2018 to investigate the seasonal distribution characteristics. Coarse PM (PM2.5–10) was more prevalent in spring, substantially due to the regional transport of dust. High loadings of coarse PM were found at night compared to daytime, which could result from high production and unfavorable dispersion conditions. Fine PM (PM2.5) constituted, on average, 54% of the total PM mass concentration, whereas it contributed more than 97% of the total PM number concentration. The number and mass concentrations of fine PM increased substantially in the winter, which was possibly due to the enhanced production of atmospheric secondary processes and coal combustion. Precursor gaseous pollutants and meteorology greatly influenced the PM distributions. Fine PM was associated more strongly with gas pollutants than coarse PM, which suggested that it largely originated from secondary production and combustion sources. High relative humidity appeared to promote the production of fine PM, whereas it facilitated the removal of coarse PM. This study highlights that different air-pollution control strategies should be used for coarse and fine PM according to the distribution characteristics and influencing factors in similar medium-sized urban areas.

Background: Self-inflicted gunshot wounds (SIGSWs) produce devastating facial defects that are challenging to reconstruct, but are rarely reported in large cohorts in the literature. This study sought to characterize these injuries, and identify parameters influencing complications and outcomes among survivors following facial reconstruction. Methods: A retrospective cohort study was performed identifying 22 patients with SIGSWs to the face reconstructed at our center from 2009 to 2019. Charts were reviewed for patient, injury, and reconstructive details and course. Outcomes were statistically compared to various parameters. Results: The most common firearm, orientation, and injured structure were the handgun (40.9%), submental (59.1%), and mandible (68.2%), respectively. Patients averaged a 21.7-day length of stay (LOS), 17.4 h to debridement, 2.6 days to bony fixation, 5.4 reconstructive surgeries, and 7 (31.8%) patients received at least one free flap. Fifteen (68.2%) patients had at least one major complication, although functional outcomes were ultimately relatively good overall. Notable outcome associations included submental orientation with a longer LOS (p = 0.027), external fixation with a longer LOS (p = 0.014), financial stressors with a shorter LOS (p = 0.031), and severe soft tissue injury with an increased total number of reconstructive surgeries (p = 0.039) and incomplete reconstruction (p = 0.031). There were no cases of suicidal recidivism. Conclusions: Reconstruction following facial SIGSW is challenging for both patient and surgeon, and carries a high rate of complications. However, patients can regain substantial function following reconstruction and the achievement of satisfactory outcomes.
Testing Lorentz Violation with IceCube Neutrinos
Authors: Zhang Huiming , Yang Lili
Published: April 2022

Lorentz violation (LV) induced by Quantum Gravity has been tested at much lower energies than the Planck scale with more and more observational evidence. In recent studies, the time of flight difference between the TeV neutrino and MeV photon from Gamma Ray Bursts (GRBs) have been used to constrain the LV energy scale, based on the energy-dependent speed variation. Here, we performed a correlation study between the updated 7.5 year high-energy starting events (HESE), neutrino alert events detected by IceCube, and a full sample of more than 7000 GRBs, and we found six GRB-neutrino candidates, including four alerts and two track events. We obtained the first order energy scale of quantum gravity, namely EQG=8−5+15×1017GeV, which was consistent with other authors‘ work. We suggest that neutrinos and anti-neutrinos can be identified, respectively, due to the delay or advance of the observed time. For future point source search study of neutrinos, the arrival time difference of different particles may have to be taken into account.
Weak Deflection Angle and Greybody Bound of Magnetized Regular Black Hole
Authors: Javed Wajiha , Riaz Sibgha , Övgün Ali
Published: April 2022

In this paper, we examine the weak deflection angle and greybody bound for a magnetized regular black hole. For this purpose, we apply the Gauss–Bonnet theorem on the black hole and obtain the deflection angle in plasma and non-plasma mediums. Moreover, we investigate graphically the effect of impact parameter on the deflection angle for regular black hole in both mediums. We examine that the deflection angle goes to infinity when the impact parameter approaches zero. We also observe that the deflection angle shows negative behaviour at q=0.6 and q=2.09, but at 0.6<q<2.09, the angle shows positive behaviour. Furthermore, we study the rigorous bound phenomenon of the greybody factor in the background for a magnetized regular black hole. Later, we analyse the graphical behaviour of greybody bound with respect to different values of ω and observe that, at small values of ω, the bound increases, but for large values, the bound decreases. After that, we examine that, when we put G=1, l=0 and q=0, all results for the magnetized regular black hole solution reduce into results of the Schwarzschild black hole solution.
Detoxified O-Specific Polysaccharide (O-SP)–Protein Conjugates: Emerging Approach in the Shigella Vaccine Development Scene

Published: April 2022

Shigella is the second most common cause of moderate to severe diarrhea among children worldwide and of diarrheal disease-associated mortality in young children in low-and middle-income countries. In spite of many years of attempts to develop Shigella vaccines, no licensed vaccines are yet available. Injectable conjugate vaccines made of the detoxified lipopolysaccharide (LPS) of S. flexneri 2a, S. sonnei, and S. dysenteriae type 1 covalently bound to protein carriers were developed in the early 1990s by John B. Robbins and Rachel Schneerson at the US National Institutes of Health. This approach was novel for a disease of the gut mucosa, at a time when live, rationally attenuated oral vaccine strains that intended to mimic Shigella infection and induce a protective local immune response were extensively investigated. Of keystone support to Shigella glycoconjugates development were the findings of a strong association between pre-existent serum IgG antibodies to S. sonnei or S. flexneri 2a LPS and a lower risk of infection with the homologous Shigella serotypes among Israeli soldiers serving in field units. In view of these findings and of the successful development of the pioneering Haemophilus influenzae type b conjugate vaccines, it was hypothesized that protective immunity may be conferred by serum IgG antibodies to the O-Specific Polysaccharide (O-SP) following parenteral delivery of the conjugates. S. sonnei and S. flexneri 2a glycoconjugates induced high levels of serum IgG against the homologous LPS in phase I and II studies in healthy volunteers. The protective efficacy of a S. sonnei detoxified LPS-conjugate was further demonstrated in field trials in young adults (74%) and in children older than three years of age (71%), but not in younger ones. The evaluation of the Shigella conjugates confirmed that IgG antibodies to Shigella LPS are correlates of protection and provided solid basis for the development of a new generation of glycoconjugates and other injectable LPS-based vaccines that are currently in advanced stages of clinical evaluation.
Vaccination Is Reasonably Effective in Limiting the Spread of COVID-19 Infections, Hospitalizations and Deaths with COVID-19
Authors: Damijan Jože P. , Damijan Sandra , Kostevc Črt
Published: April 2022

This paper uses large cross-country data for 110 countries to examine the effectiveness of COVID vaccination coverage during the delta variant outbreak. Our results confirm that vaccines are reasonably effective in both limiting the spread of infections and containing more severe disease progression in symptomatic patients. First, the results show that full vaccination rate is consistently negatively correlated with the number of new COVID cases, whereby a 10 percent increase in vaccination rate is associated with a 1.3 to 1.7 percent decrease in new COVID cases. Second, the magnitude of vaccination is shown to contribute significantly to moderating severe disease progression. On average, a 10 percent increase in the rate of vaccination leads to a reduction of about 5 percent in the number of new hospitalizations, 12 percent decrease in the number of new intensive care patients and 2 percent reduction in the number of new deaths. Finally, by comparing the data for the same period between 2020 and 2021, we also check how well vaccination performs as a substitute for lockdowns or other stringent government protection measures. Results suggest that vaccination appears to be an effective substitute for more stringent government safety measures to contain the spread of COVID infections only at a sufficiently high vaccination coverage threshold (more than 70 percent). On the other hand, vaccination is shown to be quite effective in limiting the more severe course of the disease in symptomatic patients already at moderate vaccination coverage (between 40 and 70 percent). This suggests that vaccination can also help to reduce pressure on the health system and thus benefit the overall public health of society. On the other hand, the efficient rollout of vaccines could explain the favourable economic performance in the second half of 2021 despite the severe outbreak of the delta variant.

Immune checkpoint inhibitors (ICIs) and platinum-based chemotherapy (CT) are effective therapeutic agents for the palliative treatment of metastatic non-small-cell lung cancer (NSCLC); the aim of our study was to investigate the acute and chronic renal toxicities in this setting. We collected data on 292 patients who received cisplatin (35%), carboplatin-based regimens (25%), or ICI monotherapy (40%). The primary and secondary outcomes were compared to the acute kidney injury (AKI) rate and the mean estimated GFR (eGFR) decay between groups, respectively, over a mean follow-up duration of 15 weeks. We observed 26 AKI events (8.9%), mostly stage I AKI (80.7%); 15% were stage II AKI, 3.8% were stage III, and none required renal replacement therapy or ICU admission. The AKI rates were 10.9%, 6.8%, and 8.9% for the cisplatin, carboplatin, and ICI groups, respectively, and no significant differences were observed between the groups (p = 0.3). A global mean eGFR decay of 2.2 mL/min was observed, while for the cisplatin, carboplatin, and ICI groups, the eGFR decay values were 2.3 mL/min, 1.1 mL/min, and 3.5 mL/min, respectively. No significant differences were observed between the groups. Cisplatin/carboplatin-based CT and ICIs resulted in a similar incidence of AKI and eGFR decay, suggesting the safety of their cautious use, even in CKD patients.

Published: April 2022

Diffuse large B-cell lymphoma (DLBCL) is the most common hematological malignancy in humans and dogs. Several studies disclosed some similarities between the two species, including the constitutive activation of the NF-κB pathway as a fundamental underlying pathogenetic mechanism. In humans, the downregulation of IL-1R8 is implicated in DLBCL development, but its role in dogs has not been explored so far. To gain insight into the pathogenesis of this tumor in dogs, we evaluated the mRNA and protein expression of IL-1R8 in 12 control lymph nodes obtained from dogs not bearing tumors and from 50 dogs with DLBCL. Moreover, we analyzed through qRT-PCR the expression of TLR7, TLR9, MYC, and p52 genes that are known to be involved in the IL-1R8 regulatory network. IL-1R8 and p52 were downregulated in DLBCLs compared to control lymph nodes (p < 0.001), while a higher expression of TLR7, TLR9, and MYC was observed in DLBCLs (p < 0.01). Immunohistochemistry confirmed the gene expression results, revealing a significantly lower IL-1R8 staining score in DLBCLs compared to control lymph nodes (p < 0.0001). Taken together, these results suggest that IL-1R8 downregulation may represent one of the mechanisms driving DLBCL pathogenesis in dogs, mainly through the dysregulation of the Toll-like/interleukin receptors signaling cascade and the aberrant activation of the classical NF-κB pathway.
Crocodylus porosus Sera a Potential Source to Identify Novel Epigenetic Targets: In Silico Analysis
Authors: Siddiqui Ruqaiyyah , Muhammad Jibran Sualeh , Maciver Sutherland K. , Khan Naveed Ahmed
Published: April 2022

We have previously found that sera from Crocodylus porosus contain anticancer agents and the treatment of MCF7 cells with this serum resulted in the differential expression of 51 genes. The purpose of this study was to use in silico analysis to identify genes that might be epigenetically modulated in cells treated with crocodile serum and to understand the role of potential genes as novel candidates with epigenetic therapeutic potential. The findings report five proto-oncogenes (TUBA1B, SLC2A1, PGK1, CCND1, and NCAPD2) and two tumor suppressor genes (RPLP2, RPL37) as novel therapeutic targets. Furthermore, we present a comprehensive overview of relevant studies on epigenetic regulation of these genes along with an insight into their clinical implications. Therefore, elucidating the molecules present in the serum and gut bacteria of reptiles such as crocodiles may offer insights into the role of these genes on longevity, health, disease, and life expectancy.
Undergraduate Research: A Source for Faculty Publications?
Authors: Panko Mary
Published: April 2022

Over the last two decades undergraduate students have been encouraged to problem solve in ‘the real world’ in order to construct their own subject knowledge. This generally means that students are required to carry out research in their disciplines, a process which inevitably leads to the production of quantities of data. Once their findings are reported back to faculty and have been graded, they are largely ignored, as they are ‘only’ the product of undergraduate research. However, since 2000 there has been a move to bring this type of work into the open through undergraduate research conferences in order to benefit both the students and their institutions. Nevertheless, except for a few publications within medical teaching, faculty themselves have not widely used this data for their own research, perhaps fearing its potential lack of authenticity or credibility. This paper explores a case study to examine the validity and reliability of students’ findings and considers whether the observations obtained by students can or should be made into academic publications by staff. This study comprised four cohorts, totaling 109 second-year undergraduate automotive students, who had made repeat visits to a number of automotive workshops and reviewed the workshops’ activities with a particular focus on customer service, health and safety, and waste management. Analysis of the top 25% of students’ reports revealed that a number of compliance failures were appearing on such a regular basis that these findings should be brought to the attention of the automotive industry. The paper concludes with a recommendation that under carefully controlled conditions, academics should draw on this hitherto ignored seam of research data.
Experiencing Women’s Advocacy: Connections with and Departures from a Feminist Socio-Political Movement to end Violence Against Women
Authors: Woolson Neville Diane , Gremillion Helen
Published: April 2022

This article examines how contemporary women’s advocates working in New Zealand with women experiencing intimate partner violence regard their work and how these experiences both connect with and depart from a feminist movement to end violence against women. Ten women’s advocates from ten different organisations were interviewed two times. The first interviews involved participants commenting on vignettes about hypothetical cases of intimate partner violence. The second interviews weresemi-structured and involved discussions about participants’ work and wider thoughts on the phenomenon of intimate partner violence. Interviews were analysed using Interpretative Phenomenological Analysis to identify key themes within participants’ interviews. Analysis indicated an alignment with international research illustrating an erosion of feminist perspectives in advocacy work. At the same time, it revealed areas of enduring feminist influence. Findings, therefore, suggest that the relationship between advocacy and the feminist movement to end violence against women is complicated and contradictory. Implications for further research directions are considered.

The Graduate Diploma in Not for Profit Management (GDNFPM), is one of the 160 programmes on offer at Unitec Institute of Technology. It was established in 1996 in response to a call from the community sector to improve the capability and professionalism of practitioners working in the Not for Profit (NFP) sector. It is a unique programme for Unitec as it caters to its target community by organising the credited papers in blocks of 3 days to make it accessible to people working in community organisations and creating minimal disruption to the workplace. It is delivered in 6 centres nationwide and has a strong demand in the Pacific. GDNFPM has been delivered in Samoa, Fiji, Vanuatu and Papua New Guinea for the past 12 years. Between 2009 and 2011 the GDNFPM worked in partnership with Te Rau Matatini, to provide the programme to a Māori cohort from the Māori Mental Health sector. Te Rau Matatini is a national Māori Mental Health workplace development organisation. The intake over this period enabled 59 students to participate on a full scholarship provided by Te Rau Matatini. The programme was delivered via a noho marae environment (living- in together) and resulted in 32 Māori graduates in 2010 /11. After three years the relevance of content, course structure, and tutoring style most suited to an all Māori cohort were able to be gauged. The GDNFPM has been able to evidence higher success and completion rates for Māori students in the programme via the noho environment where student support including pastoral, academic and cultural, have been provided in class and after hours. The personnel support has been provided by a three way partnership agreement with Te Rau Matatini (pastoral care), Maia Māori Development Centre at Unitec (pastoral and cultural support), and GDNFPM (academic, pastoral and cultural support).

LATVIAN SEMI-NATURAL GRASSLANDS IN THE SOCIO-ECOLOGICAL EXTINCTION VORTEX: THE EVIDENCE AND RESEARCH GAPS
Authors: Rūsiņa Solvita
Published: April 2022

INTRODUCTION

Semi-natural grasslands depend on active management by certain societal actors, and can therefore be defined as socio-ecological systems (Herzon et al., 2021). Semi-natural grasslands of the European Boreal biogeographical region are considered to be caught in a socio-ecological extinction vortex (Herzon et al., 2022).  Our aim was to look at the evidence for the extinction vortex of Latvian semi-natural grasslands at the national level, and to describe the main directions in which research is insufficient.

MATERIAL AND METHODS

We conducted a scientific literature review and collected official agricultural and habitat conservation statistics.

RESULTS

Published studies are dominated by ecological aspects of semi-natural grasslands in Latvia. At the national level, there is little evidence available about all four interlinked and mutually reinforcing socio-economic processes operating in the extinction vortex (Herzon et al., 2022): 1) agricultural production; 2) policy, research and development; 3) vocational education in the fields of agricultural sciences and 4) the public’s experience with semi-natural habitats.

DISCUSSION

The success of semi-natural grassland conservation depends on how well social-ecological system (SES) thinking has been applied through conservation planning and implementation (Krievins et al. 2018; Fischer et al. 2021). Therefore, conservation should approach semi-natural grasslands as socio-ecological systems rather than merely ecosystems. In Latvia, this approach has not yet been fully appreciated.

CONCLUSIONS

There is a lack of understanding of semi-natural grasslands as socio-ecological systems in Latvia both in the governmental and non-governmental sector, as well as in the research community. The main research gap is in inter- and transdisciplinary approaches to semi-natural grassland conservation.
Detection of Heart Rate Variability from Photoplethysmography (PPG) Signals Obtained by Raspberry Pi Microcomputer
Authors: Pamuk Ziynet , Kaya Ceren
Published: April 2022

Photoplethysmography (PPG) signals are signals obtained as a result of optically measuring volumetric changes in capillaries. Volumetric changes in capillaries also depend on the work of heart. According to recent researches, it has been seen that PPG signals contain a lot of information about the physiological and biological state of related person. Most of these studies are based on the analysis of characteristics and waveforms of PPG signals obtained with a single wavelength in time and frequency domains. In this study, 10 minutes of data was taken from the left index finger of a 24-year-old male, which was positioned horizontally using a MAX30100 sensor and Raspberry Pi 4 microprocessor kit. Experiments are carried out in the fully resting state of a male volunteer in outdoors and stressful environments. While the MAX30100 sensor shows the heartbeat on the screen, it also gives PPG signal data, which is a single wavelength, into a .csv file as received data.

Fast, reliable and comfortable transportation of people increases the level of livability in cities. It also influences people's quality of life. Therefore, researches are needed to improve transportation services. Various models are developed to analyze the transportation services but each of which has its own advantages and disadvantages. Today, companies collect large amounts of data to improve their service quality. To survive in competition environment, they must use the collected data in order to create value for their customers and employees. There are many factors that affect the transportation services. Therefore, it is difficult to solve the problems in transportation services using classical methods. The main goal of our study is to determine the bus ticket price accurately. In this study, k-means algorithm, which is popular because of its simplicity and versatility, is firstly used to discover more meaningful information. Then the price, which is one of the most important elements of passenger transportation, is forecasted using six different forecasting model including linear regression, support vector regression, regression tree, gaussian process regression, genetic algorithm based artificial neural network, and ensemble model. The results of this study showed that proposed forecasting models can meet expectations in dynamic environmental conditions.
