Authors: Mheissen Samer , Seehra Jadbinder , Khan Haris , Pandis Nikolaos
Published: February 2022

Objectives

To examine whether optimal calculations of the sample size are being used in longitudinal orthodontic trials.

Materials and Methods

Longitudinal orthodontic trials with a minimum of three time points of outcome assessment published between January 1, 2017, and December 30, 2020, were sourced from a single electronic database. Study characteristics at the level of each trial were undertaken independently and in duplicate. Descriptive statistics and summary values were calculated. Inferential statistics (Fisher's exact test and logistic regression) were applied to detect associations between reporting of a sample size calculation and the study characteristics.

Results

A total of 147 trials were analyzed; 75.5% of these trials reported a sample size calculation with none reporting optimal sample size calculation for longitudinal trials. Most of the longitudinal orthodontic trials did not report the correlation and the number of longitudinal measurements in calculating the sample size. An association between reporting of a sample size calculation (yes or no) and the type of journal (orthodontic and non-orthodontic) was detected with higher odds of reporting a sample size calculation in orthodontic journals than in non-orthodontic journals (3.04; 95% confidence interval, 1.4-6.59; P < .01).

Conclusions

The findings of this study highlighted that the undertaking of optimal sample size calculations in longitudinal orthodontic trials is being underused. Greater awareness of the variables required for undertaking the correct sample size calculation in these trials is required to reduce suboptimal research practices.

Authors: Pant Megha
Published: February 2022

The term ‘subaltern’ incorporates the entire people that are subordinates in terms of class, caste, gender and rank, or in any other way. When it operates in terms of class, gender and caste, it is more psychological than physical.  Antonio Gramsci coined the term subaltern to identify the cultural hegemony (According to Merriam Webster the word hegemony means the social, cultural, ideological, or economic influence exerted by a dominant group).

This paper endeavors to highlight the voiceless Marginalized women in Shivani’s Bhairavi: The Runaway (a translation from the original Hindi text, Bhairavi rendered in English by Priyanka Sarkar). Shivani aka Gaura Pant was a very prolific and voluminous writer, she has many novels, short stories and essays to her credit. The English translation of her works give an insight into the deeper psychological understanding of women. Shivani’s purpose is to give voice to the marginalized women in the society and to explore the discrimination order of caste, gender and class.

Evaluation of the Impact of Tractor Field Works on Changes in Selected Elements of Engine Oils
Authors: Gołębiowski Wojciech , Zając Grzegorz , Sarkan Branislav
Published: February 2022

Tractors are used for various types of field work, as well as for transport on public roads, in difficult and changing environmental conditions. The main goal of the study was to analyze the changes of trace elements in engine oil during various field works. For this purpose, engine oils from two tractors were selected for the study. These tractors were coupled with: a cultivator, a reversible plow, a tillage-sowing unit, and a trailer. The samples were taken at the beginning and after the field work with a given unit was completed. The instrumental chemical analysis method HDXRF was used to determine changes in the content of the trace elements: Cr, Cu, Fe, Pb, Ni, Ca, P, Zn, and Mo in the engine oil. The comparison of oil from tractors coupled with various agricultural machines allowed the conclusion that the distribution of the consumption of tested metals, as well as the concentrations of individual elements, differed significantly depending on the coupled machine. The research showed that agricultural treatments with a cultivator caused the highest percentage of wear-induced changes in the content of metal elements such as Cr, Cu, and Pb. On the other hand, the operation of a tractor coupled with a tillage-sowing unit resulted in the vehicle’s accelerated wear.
Health consequences of vitamin D deficiency in the human body
Authors: Glibowski Paweł , Iłowiecka Katarzyna , Środek Karolina
Published: February 2022

Vitamin D is extremely important for the proper functioning of the body. The most commonly known role of vitamin D is its participation in regulation of calcium-phosphate metabolism and bone mineralization. This role is crucial in the prevention of rickets in children and osteoporosis in the elderly. In recent years, numerous studies have confirmed the pleiotropic effects of vitamin D. Proper vitamin D levels in blood have a positive effect on overall health, thus reducing the risk of many diseases. Vitamin D plays, inter alia, a positive role in some diseases of the gastrointestinal tract (inflammatory bowel disease), nervous system (Parkinson disease, Alzheimer disease), and cardiovascular disease (atherosclerosis). Additionally, its positive protective effect in the case of neoplastic and immunological diseases has been noted. Some studies also confirm the relationship of vitamin D deficiency to obesity and depression. In the event of these diseases, it is possible to prevent disease and support the process of treatment by maintaining appropriate levels of 25(OH)D in the blood. Besides, sufficient blood vitamin D levels reduces the risk of developing respiratory tract infections and suppresses cytokine storm, which is responsible for most COVID-19 deaths.

The aim of the study was to present the current state of knowledge regarding the role of vitamin D in the human body, especially in the context of the impact of its abnormal level on the development of various diseases.

Authors: Chen Ruxue , Sulaimani Hani Jamal , Hoon Kim Sae
Published: February 2022

In the process of modernisation, the essence of virtual 3D animation scene modelling is to enhance the rendering effect of animation, so designers need to understand and skilfully use virtual reality technology. During the scene modelling, the system perception module will obtain the perception information on the basis of understanding the behaviour state of the role, and thus provide the data basis for the emotion module and the behaviour module. Among them, the emotion module is mainly used to adjust the emotional changes of the role, and the behaviour module is mainly used to build the motion database. So this article after understanding the current situation on the basis of the virtual 3D animation scene modelling, use the geometric centroid algorithm for virtual 3D animation scene modelling technology to realise in-depth understanding, and the final results prove that the build system can not only clear intuitive present animation image, but can be in effective connection also, on the basis of multiple motion clips, to maintain the original movement in detail.

The paper establishes a related differential equation model about changes in financial interest rates. It uses information related to liquidity to feedback the law and stability of differential equations in interest rate changes. The article applies stochastic processes and partial differential equations to complex financial networks to confirm node yields in financial market networks. It confirms the existence of interest rate stickiness in Chinese financial markets. The advantage of this interest rate model is that when the external economic environment changes, the state of interest rates will also change accordingly.
AtanK-A New SVM Kernel for Classification
Authors: Tian Meng , Li Hongkui
Published: February 2022

The efficiency of support vector machine in practice is closely related to the optimal selection of kernel functions and their hyper-parameters. A novel kernel, namely the arctangent kernel, is proposed in this paper. Compared with the Gaussian kernel, the new proposed kernel has a quick similarity descent in the neighborhood of the inspection sample and a moderate similarity descent toward the infinity of the inspection sample. The experimental results on two simulated data sets and some UCI data sets show that the new proposed kernel function has better effectiveness and robustness compared with the polynomial kernel, the Gaussian kernel, the exponential radial basis function, and the former proposed kernel with moderate decreasing.

Authors: Niu Lifen , Durakoglu Abdulhamit
Published: February 2022

To study the teaching of sports science in athletics, this paper adopts the method of a nonlinear mathematical equation, According to the explosive power = force * speed and hill force speed equation, the best matching value between the load weight and the muscle contraction speed when the athlete reaches the maximum explosive power is obtained by the mathematical method, to achieve the objective of quantifying and scientifying the maximum explosive power training method according to the individual ability of the athlete. The results show that the training intensity is slightly lower than the optimal strength load (about 30%F0) and faster than the optimal movement speed. Jumping events adopt load weight higher than the optimal load to 50% F0 and load intensity slightly slower than the optimal speed combination for training; Conclusion: According to the characteristics of track and field events, this paper discusses the application of the research results in the training of athletes’ explosive development in different track and field events, to achieve better training effect and improve students’ athletic ability.

Authors: Odhiambo Judith Achieng , Aguyoh Joseph Nyamori
Published: February 2022

Field trial to determine the optimum soil moisture level for enhanced performance of cucumber was conducted in polyethylene covered rain shelter for two seasons in 2017 and repeated in 2018. The research was conducted at Rongo University Research and Teaching field. Three seeds of cucumber ‘Ashley’ were sown directly in 3.5 litre plastic pots containing 8 kg of sterilised air-dried growth medium made up of sand and top soil in the ratio of 1:2. The treatments were four levels of water applied at 100 % (control), 80 %, 60 % and 40 % pot capacity. The experimental design was completely randomised block design replicated three times. Data on the plant growth, flower production and yield were subjected to Analysis of Variance (ANOVA) and mean separation tests at p ≤ 0.05 level of significance. There were significant differences on the vine growth, internodes length and diameter as a result of Water Stress (WS) levels. The treatments also significantly affected the Relative Leaf Water Content (RLWC) and Relative Leaf Expansion Rate (RLER) but did not affect the number of leaves per vine. Fruit firmness was also affected by water stress. To optimise the productivity of cucumber, the soil moisture level should be maintained to at least 80 % of the field capacity throughout its productive phase.
Political rationalities related to the public participation as exemplified by the Warsaw #housing2030 project
Authors: Zubrzycka-Czarnecka Aleksandra
Published: February 2022

This article analyses political rationalities positioning residents in decision-making in the context of #housing2030 project in Warsaw, Poland. The paper applies a governmental approach, a policy analysis tool reconstructed (on the ground of existing studies) by Greg Marston and Catherine McDonald (2006). As reported in the article, two political rationalities were identified: (1) public participation designed in the context of local communities and neighbourhoods and (2) public (tenant) participation designed in the context of neoliberal governance in housing. It was found that in the case of the #housing2030 project, the contradiction of political rationalities leads to an incoherent vision of public participation in housing policymaking and to some residents (social tenants) being treated differently. The article argues that this contributes to the micro-practices of social scepticism and distrust on the part of tenant organisations and urban movements towards the #housing2030 project.
Elevated resting heart rates are a risk factor for mortality among patients with coronavirus disease 2019 in Wuhan, China
Authors: Jin Han , Yang Shengwen , Yang Fan , Zhang Long , Weng Haoyu , Liu Shengcong , Fan Fangfang , Li Haichao , Zheng Xizi , Yang Hongyu , Zhang Yan , Zhou Jing , Li Jianping
Published: February 2022

Background:

We evaluated the association between higher resting heart rates (RHRs) and adverse events in COVID-19 patients.

Methods:

One hundred and thirty-six patients with laboratory-confirmed COVID-19 were admitted. Outcomes of patients with different RHRs were compared.

Results:

Twenty-nine patients had RHRs of <80 bpm (beat per min), 85 had 80–99 bpm and 22 had ≥100 bpm as tachycardia. Those with higher RHRs had lower pulse oxygen saturation (SpO2) and higher temperatures, and there was a higher proportion of men upon admission (all P < 0.05). Patients with higher RHRs showed higher white blood cell counts and D-dimer, cardiac troponin I (TnI), N-terminal pro-B-type natriuretic peptide and hypersensitive C-reactive protein levels, but lower albumin levels (all P < 0.05) after admission. During follow-up, 26 patients died (mortality rate, 19.1%). The mortality rate was significantly higher among patients with tachycardia than among the moderate and low RHR groups (all P < 0.001). Kaplan–Meier survival curves showed that the risks of death and ventilation use increased for patients with tachycardia (P < 0.001). Elevated RHR as a continuous variable and a mean RHR as tachycardia were independent risk factors for mortality and ventilator use (all P < 0.05) in the multivariable adjusted Cox proportional hazards regression model.

Conclusions:

Elevated average RHRs during the first 3 days of hospitalisation were associated with adverse outcomes in COVID-19 patients. Average RHRs as tachycardia can independently predict all-cause mortality.
New insights of epigenetics in vascular and cellular senescence
Authors: Zhu Menglin , Ding Qian , Lin Zhongxiao , Chen Xu , Chen Siyao , Zhu Yizhun
Published: February 2022

Vascular senescence plays a vital role in cardiovascular diseases and it is closely related to cellular senescence. At the molecular level, aging begins with a single cell, and it is characterized by telomere shortening, mitochondrial dysfunction, stem cell exhaustion, epigenetic changes, and so on. Epigenetics is an independent discipline that modifies DNA activity without altering the DNA sequence. The application of epigenetics helps to alleviate the occurrence of human diseases, inhibit senescence, and even inhibit tumor occurrence. Epigenetics mainly includes the modification of DNA, histone, and noncoding RNA. Herein, the application of epigenetics in vascular senescence and aging has been reviewed to provide the prospects and innovative inspirations for future research.

Published: February 2022

Introduction

Trypanosomosis is an important disease of dromedary camels caused by the pathogenic protozoanTrypanosoma evansi. This study aimed to compare three different tests for its diagnosis in this species: conventional microscopy, the card agglutination test for trypanosomosis/T. evansi(CATT/T. evansi) and real-time PCR.

Material and Methods

Whole blood and serum samples collected from 77 dromedary camels of Abu Dhabi, United Arab Emirates, were analysed with the test methods stated. Statistical analysis was done using McNemar’s chi-squared test, and Cohen’s kappa index (κ) was calculated.

Results

We obtained results with positivity of 18% (14/77) by microscopy, 22% by CATT (17/77) and 60% (46/77) by real-time PCR, with the chain reaction detecting at a respectively three- and two-fold greater rate than the other techniques. Analysis of the data revealed a relative sensitivity of 30.4% and 37.0% for microscopy and CATT, respectively, compared to real-time PCR. The difference between the real-time PCR’s sensitivity and those of the other methods was statistically significant, with X2values of 30.03 and 20.1, respectively (df = 1 and P = 0.05 in both cases). Agreement of microscopy results with those of with CATT was good (κ = 0.72; 95% CI = 0.62–0.82). Cohen’s kappa index showed fair agreement of real-time PCR with microscopy (κ = 0.26; 95% CI = 0.16–0.36) whereas it was in poor agreement with CATT (κ = 0.09; 95% CI = 0.02–0.15).

Conclusion

Real-time PCR was found to be more sensitive than microscopy and CATT.

Las Micro, Pequeñas y Medianas Empresas (MiPymes), impulsan la economía en el ámbito global, nacional, regional y local. En México, coexisten un gran número de MiPymes, lo anterior, de acuerdo con el número de trabajadores; en ellas se concentran casi la tercera parte del personal ocupado total del país y más de la mitad del Producto Interno Bruto (PIB) nacional; dejando un número muy reducido en comparativa con los grandes establecimientos. Pese a lo anterior, el nivel de competitividad que muestran las MiPymes señaladas resulta demasiado bajo, derivado de factores tales como la falta de implementación de Tecnologías de Información (TI) en sus actividades clave, que, en consecuencia, limita el incremento de la competitividad en el mercado en el que realizan su actividad comercial. El análisis situacional en el ámbito local no es prolífico, por lo que existe la necesidad de realizar el estudio de las condiciones en que operan las v comerciales respecto de la integración de TI, por lo que el objetivo del presente será proponer un método de seis pasos de implementación de TI en MiPymes comerciales en Xalapa, Ver., México, con base en sus diversas necesidades, y de esa manera, incrementar su competitividad empresarial.

ABSTRAK Penelitian ini diawali dengan menumbuhkan dari daun salam yang telah disterilkan menggunakan etanol 70% dan natrium hipoklorit. Skrining antibakteri dilakukan dengan menggunakan uji antagonis sebagai screening pertama melawan Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis, Salmonella thyposa. Penelitian ini menghasilkan 2 isolat fungi. Fungi endofit aktif difermentasi dan ekstraksi dengan etil asetat (EtOAc) dan metanol. Aktivitas antibakteri dari ekstrak EtOAc dan metanol diuji aktivitasnya menggunakan metode difusi disk. Satu isolat fungi endofit (XP1) terhadap lima dari bakteri yang diuji adalah S. aureus, P. Aeruginosa, E. Coli, S. thyposa, dan B.subtilis, memiliki daya hambat terbesar pada bakteri uji S. thyposa dengan diameter daya hambat sebesar 14,00 mm. Sedangkan pada isolat fungi endofit (XP2) terhadap lima dari bakteri yang diuji adalah S. aureus, P. Aeruginosa, E. Coli, S. thyposa, dan B.subtilis, memiliki daya hambat terbesar pada bakteri uji S. thyposa dengan diameter daya hambat sebesar 22,00 mm. Berdasarkan analisis filogenetik isolat XP 1 memiliki kemiripan dengan Penicillium sp. (homology 87%) sedangkan isolat XP2 memiliki kemiripan dengan Colletotrichium gloeosporioides (homology 98%).

ABSTRACT This research was begun by growing from bay leaves that had been sterilized using 70% ethanol and sodium hypochlorite. Antibacterial screening was carried out using antagonistic tests as the first screening against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis, Salmonella thyposa. This study produced 2 fungi isolates. Active endophytic fungi are fermented and extracted with ethyl acetate (EtOAc) and methanol. Activity. The antibacterial activity of EtOAc and methanol was tested for its activity using the disk diffusion method. One isolate of endophytic fungi XP1 against five of the bacteria tested was S. aureus, P.aeruginosa, E.coli, S. thyposa, and B.subtilis, which had the greatest inhibition on S. thyposa test bacteria with inhibitory diameter of 14.00 mm. Whereas the XP2 endophytic fungi isolates against five of the tested bacteria were S. ureus, P.aeruginosa, E.coli, S.thyposa, and B.subtilis, which had the greatest inhibition on S. thyposa test bacteria with inhibition diameter of 22.00 mm. Based on phylogenetic analysis isolate XP 1 has similarities with Penicillium sp. (homology 87%) while isolate XP2 Colletotrichium gloeosporioides (homology 98%).

Pain is an unpleasant sensation and can be felt as sore sensation. This can be caused by mechanical, chemical or physical stimulation that could cause damage to the tissueand trigger the release of certain substances called pain mediators, such as histamine, bradykinin, leukotrienes and prostaglandins. Pain overcome by giving analgesic drugs. This study aims to determine the effectivity and effective duration of bitter melon (Momordica charantia L.) leaf extract as analgesic in mice (Mus musculus). The test method used in this study is the Hot plate method. This study was divided into 5 treatment groups animals with 5 experimental animals in each group. Animal treatment of this study consist of a negative control group using CMC-Na (0.5%), a positive control group using Paracetamol, a suspension group of pare leaf ethanol extract with a dose of 0.212mg / 20gBW. , the ethanol extract suspension group of bitter melon leaves with a dose of 0.423mg / 20gBW, the suspension group of ethanol extract of pare leaves with a dose of 0.635mg / 20gBW. The results of this study indicate that the ethanol extract of 96% bitter melon leaves has activity as an analgesic in mice with the best dose of 0.635mg / 20gBW and  the highest duration of analgesic activity was in 40 minutes, these activity was the closest result to positive control of paracetamol in mice.

Pedicab drivers have low economic level and smoking is a social habit that very risk of experiencing lung function disorders, but are also classified as having routine physical activity while pedaling the rickshaw. The purpose was to determine physical activity and risk of COPD from the value of lung function in pedicab drivers in Surabaya. The research design was cross-sectional research in March-December 2018. The location used was in the vicinity of the Surabaya area. The research variables included: pulmonary function disorders by measuring spirometry and physical activity using the International Physical Activity Questionnaire (IPAQ). The data analysis was descriptive. The total respondents were men, amounting to 188 people. Most of the respondents had moderate lung function disorders at 82.45%. Respondents with impaired lung function had high physical activity profile of 1 person (0.61%); moderate physical activity profile was 155 people (95.09%) and and low physical activity profile was 7 people or 4.29%. Respondents with non-impaired lung function have a moderate physical activity profile of 25 people (100%). Therefore, it was necessary to further research the factors that can affect the decline in lung function of pedicab drivers in addition to physical activity.
