Published: January 2022

Abstract
Introduction: Leukemias are involving the bone marrow and the soft tissues in inner parts of the bones, where new blood cells are formed. This malignancy is the most common pediatric cancer, which its etiologic causes are not well understood. This multifactorial disease is believed to linked with genetic and non-hereditary environmental factors. Cytogenic analyses of chromosomal abnormalities provide diagnostic and prognostic values in leukemia patients. Given the high prevalence of viral diseases and clinical suspicions on the relationship between certain viral infections and leukemia, it is necessary to investigate this possible relationship, especially in third-world countries. The present study recruited 65 children with leukemia (AML, CML, or ALL) who were presented to two tertiary hospitals. At first, all the patients underwent testing for HBV, HCV, CMV, EBV, and HIV. Bone marrow specimens were studied for identifying possible chromosomal abnormalities in cytogenic investigations. According to our findings, there was a relationship between incidence of leukemia, the 12:21 chromosomal translocation and CMV infection. Therefore, preventing CMV infection can lead to a reduced incidence of leukemia. It is expected that the findings of this study enlighten the scientists to conduct more extensive research on the relationship between viral diseases and leukemia in third-world countries.Method:The present study recruited 65 children with leukemia (AML, CML, or ALL) who were presented to two tertiary hospitals.

Published: January 2022

Abstract
Background: Psychological tests are necessary to assess and assess the mental state of individuals. Mental health is one of the important psychological indicators and is increasingly considered as having various aspects of well-being. The Mental Health Continuum-Short Form (MHC-SF) is a 14-item instrument that assesses mental health, focusing on emotional, psychological, and social well-being. The present study examined the psychometric properties of the Persian version of the MHC-SF among adolescents, focusing on its factor structure, internal consistency, construct validity, and gender measurement invariance.Methods: The population of this study was Iranian adolescents between 11 and 18 years old who were enrolled in the seventh to twelfth grades. A convenience sample of 822 Adolescents from four large cities in the Iran (Tehran, Zanjan, Hamedan and Ghazvin) participated in the present study. Questionnaires were completed online. Statistical analyses to evaluate the factor structure, internal consistency, construct validity, gender and age factorial invariance were performed in SPSS and LISREL.Results: The results of confirmatory factor analysis supported the 3-factor structure of MHC-SF (emotional, psychological, and social well-being). Reliability was confirmed by Cronbach's alpha method and composite reliability (>.7). Measurement invariance were confirmed among girls and boys. Convergent and divergent validity were also evaluated and confirmed by correlating the test score with similar and different tests.Conclusion: This study examined and confirmed the psychometric properties of GHQ in the Iranian adolescent community. This instrument can be used in psychological research and diagnostic evaluations.

Authors: Beypinar İsmail , Tercan Mustafa , Tugrul Fuzuli 
Published: January 2022

Abstract
Purpose
Two treatment modalities are considerable for radiation therapy: short-course radiotherapy and immediate surgery or chemoradiation with 5-Fluorouracil based chemotherapy with delayed surgery. In this study, we try to evaluate the real-life treatment approaches of medical, radiation, and surgical oncologists for neoadjuvant treatment of rectal cancers.
Method
The online survey form was established via Google Forms. The survey was taken voluntarily by medical oncologists, radiation oncologists, surgical oncologists, and general surgeons.
Results
One hundred eighty-three of the participants were medical oncologists while 36 were radiotherapists and 36 were surgeons. Most of the study population preferred long-course radiation therapy and chemotherapy which was consisting eighty-five percent. Two-thirds of the participants apply chemotherapies before operation. The most frequent chemotherapy cycles for the pre-operative setting were ‘three’ or ‘four-or-more’ with the percent of 27,8 and 25,1 respectively. Medical oncologists had a significantly higher tendency of offering chemotherapy between radiation therapy and surgery compared with the other groups. The optimal time of surgery was different between groups. There was no difference among groups between surgery and the ‘watch & wait’ strategy. A significant difference was observed between groups in offered neoadjuvant chemotherapy regimens.
Conclusion
In our study, we found the new pre-operative chemotherapy regimen with short-course radiotherapy was slowly adopted in current practice. Also, medical oncologists tend pre-operative chemotherapy compared with other groups. The optimal surgery time for patients receiving neoadjuvant treatment is still controversial.

Abstract
Purpose: Para-aortic adipose tissue (PAT) is the local adipose tissue that externally surrounds the aorta. It contributes significantly to aortic atherosclerosis and enlargement. Studies conducted with computed tomography and magnetic resonance have shown that individuals with aortic aneurysm had more PAT than healthy individuals. In this study, we measured PAT for the first time using transthoracic echocardiography (TTE).The aim of this study is to investigate the possible relationship of TTE measured PAT with ascending aortic width.Methods: PAT was defined as the hypoechoic space in front of ascending aortic 2 cm above the sinotubular junction at the end of the systole. Patients were divided into 2 groups according to the presence of dilatation in the ascending aorta using Roman's classification (aortic size index, ASI). ASI of less than 21 was considered no aortic dilation and an ASI of 21mm/m2 or greater was considered to have aortic dilation.Results: A total of 321 unselected patients were divided into the ascending aortic dilatation (AAD) group (n=96) and the normal ascending aorta diameter group (n=225 patients). PAT was significantly higher in the AAD group compared with the non-ADD group (0.9 (0.48) vs. 0.7 (0.91) mm, p < 0.0001). Univariate and multivariate logistic regression analysis revealed that PAT (OR: 3.005, 95%CI (1.445–6.251)) were significantly associated with AAD.Conclusion: Our results showed an association between PAT measured by transthoracic echocardiography and ascending aorta width. PAT appears to be an important follow-up parameter in patients at risk of developing aortic aneurysm.

Abstract
Background: To summarize F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) imaging features of relapsing polychondritis (RP) and to evaluate the feasibility of imaging parameters in the estimation of pulmonary function and disease activity in a cohort of RP patients with airway involvement.Methods: Thirty RP patients with respiratory symptoms who underwent PET/CT scans before corticosteroid treatment were included. Six patients underwent another post-therapeutic PET/CT scan. Imaging features were described by consensus, and FDG uptake values (SUVmax, PET FDG Burden Score (PETFBS) and PETCTindex) either for global cartilages or for the airway were calculated to correlate with clinical symptoms, pulmonary functional parameters and serological inflammatory markers C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR).Results: Laryngo-tracheo-bronchial involvement was detected by PET/CT for all patients with increased FDG uptake in 28/30 patients. The incidence of positive PET was higher in segments with wall thickening (52.68% vs. 15.48%) but was not associated with calcification or stenosis. A total of 46.7% (14/30) of patients presented with sole respiratory symptoms, while PET/CT revealed additional abnormalities in addition to laryngo-tracheo-bronchia. FDG uptake values negatively correlated with disease duration but not with fever. All FDG uptake values showed a positive correlation with FEV1/FVC, with the highest coefficient for SUVmax in the airway (rs =0.628). CRP and ESR were negatively correlated with PETFBS and PETCTindex but not with SUVmax. The largest Spearman correlation coefficient resulted in PETFBS in the airway (rs =0.67). Re-examination PET/CT in 6 patients revealed partial therapeutic response (n = 4), stable disease (n = 1) and progressive disease (n = 1).Conclusion: PET/CT is a valuable tool for assessing RP with airway involvement, especially for patients who present with sole respiratory symptoms. SUVmax and PETFBS have distinct advantages in the clinical evaluation of RP with respect to pulmonary function and disease activity.

Considering the overall morphological traits, a wide variation was detected between genotypes. According to the molecular findings obtained. The polymorphism rate ranged from 0–100% and the average polymorphism rate was calculated as 80%.ConclusionPresent findings revealed the diversity in tomato genotypes collected from Erzincan province and may constitute the bases for further breeding studies in tomato and will bring an integrity in tomato identification studies.
The Effect of Activated Carbon Using on Aroma and pH Values in Yogurt Fermentation
Authors: Zümrütdal Emin 
Published: January 2022

Abstract
Yogurt is a known food item all over the world. Consuming yogurt can be quite difficult for people with lactose intolerance at times. In addition to its active carbon adsorbent feature, it is a lactose chelate. It is aimed to use yoghurt prepared by using activated carbon for nutritional purposes. For this purpose, aroma and pH changes in yogurt made with activated carbon compared to classical yogurt production were studied. It was determined that the active carbon usage method used in the study did not cause any aroma change in yoghurt, however, it increased the pH. This result makes us think that lactose cannot be used by yogurt microorganisms and that yogurt with activated carbon may be an alternative for lactose intolerant people who want to consume yogurt.

Published: January 2022

Abstract
BackgroundThe extent of leptospirosis is unknown in Sudan and it might be mistaken for other more common febrile infectious diseases. Leptospirosis might also be associated with renal diseases that are common in Sudan. We intended to explore the existence of human leptospirosis in suspected high risk patients in Khartoum, Sudan, via sero-screening random febrile patients and those undergoing renal dialysis.MethodsThis is a pilot exploratory study that was conducted in 6 months period from April to September of 2013. Hospitals were selected conveniently following a non-random sampling approach. A total of 119 febrile patients (with or without definitive diagnosis) and patients under renal dialysis were included and their serum specimens, clinical and demographic data were collected. Sera were screened qualitatively for the existence of anti-leptospiral IgM antibodies using rapid lateral flow immunosorbent assay. Ethical clearance and official permissions were obtained.ResultsOut of the total 119 patients, 57 (47.9%) had end stage renal disease and were under dialysis at Renal Dialysis Unit in Asbab Charity Hospital in Bahri, 47 (39.5%), were febrile with unknown origin attending the Tropical Medicine Hospital in Omdurman, and 15 (12.6%) were febrile and were diagnosed as having malaria or typhoid and attended Yastabshiron Medical Centre and Bashauer Teaching Hospital. The overall prevalence of anti-leptospiral IgM antibodies among all 119 screened patients was 7%. The prevalence among the 57 with end stage renal disease was 9%, and among the 47 with fever of unknown origin was 6%. The prevalence among the 15 with fever of known origin (diagnosed as malaria or typhoid) was 0%. Almost all positive patients had recurring episodes of fever, are in close contact with livestock, were farmers and have natural untreated source for drinking water.ConclusionLeptospirosis is probably a common febrile condition and can be easily considered as one of the major causes of chronic kidney disease affecting people in this country. A national sero-screening for leptospirosis among those living in high risk geographical areas and those at occupational risk is highly recommended.

Published: January 2022

Abstract
Climate change has been observed for hundreds of years by plant specialists of three Odawa Tribes in the Upper Great Lakes along Lake Michigan. Sleeping Bear Dunes National Lakeshore is the focus of two National Park Service-funded studies of Odawa Traditional Ecological Knowledge (TEK) of plants and ecosystems and climate change impacts on these. Data collected during these ethnobotany studies were designed to contribute to a Plant Gathering Agreement between the tribes and the park. This essay provides an analysis of these observations derived from 95 ethnographic interviews conducted by University of Arizona anthropologists. Odawa people recognize in the park 288 plants and five habitats of traditional and contemporary concern. Tribal representatives explained how 115 of these traditional plants and all five habitats are known from multigenerational eyewitness accounts to have been impacted by climate change.

Abstract
Parasitoids may deposit a second clutch of eggs on a host that has been parasitized by the same parasitoid species. This is termed “superparasitism”. Wolbachia infection increases the superparasitism frequency of Trichogramma females. We investigated the outcome and fitness cost of inter-strain intrinsic competition between Wolbachia-infected thelytokous strain (TDW) and uninfected bisexual strain (TDB) of Trichogramma dendrolimi. To determine the developmental rate of both strains, the size of immature stages of T. dendrolimi offspring at different times after parasitization was measured in single parasitism and superparasitism conditions. The results showed increased superparasitism by Wolbachia-infected females compared to uninfected females, regardless of the time interval between oviposition; Trichogramma females were unable to distinguish between host eggs previously parasitized by TDB or TDW females. When the first oviposition was performed by TDB females, the TDB offspring outcompeted TDW offspring deposited later. However, although the TDW offspring was deposited 8 h earlier than the TDB offspring, it gained no advantage over TDB offspring. Regardless of parasitism conditions, the differences in development rate and time between TDW and TDB offspring were not significant. This study revealed that albeit TDW females presented a higher tendency of superparasitism than TDB females, TDB offspring outcompeted TDW offspring even when the latter was deposited 8 h earlier. The negative effects of Wolbachia infection on the competitive ability of TDW offspring inside the host eggs were due to offspring’s low fitness rather than delayed development.

Supplier selection is a complex problem in the current Industry 4.0 era. The large number of suppliers with different performance qualities makes it difficult for the company's internal parties to choose the appropriate supplier. The suitability of quality suppliers needed to supply raw materials needed by the industry is an important matter to be resolved. In the hand tractor assembly industry, this small and medium industry is also very dependent on the availability of supply materials, and of course it also depends on the selection of the supplier itself. In this study, the object of research is the 151 hand tractor assembly manufacturing industry using 10 main criteria for selecting suppliers. Each criterion has a weight that is calculated using the Fuzzy AHP method so as to obtain alternative supplier results that are displayed in order.
A supplier is a company or individual that provides the raw materials needed by the company and its competitors to produce certain goods. In this study, a decision support system for supplier selection at the company has been developed using the AHP fuzzy method. The results of this study are expected to help companies in selecting suppliers that match the predetermined criteria. In building a decision support system that provides supplier recommendations, the authors apply the AHP fuzzy method in the process. With the Supplier Selection Decision Support System Using the AHP Fuzzy Method, it can help companies in selecting suppliers. Based on the research that has been done, suggestions can be made for a Decision Support System for Supplier Selection Using the Fuzzy AHP Method so that in the future it can facilitate the use of a more dynamic system

Even though natural sources of air pollution account for over 50 % of sulphur compounds, 93 % of nitrogen oxide which are the most dangerous artificial anthropogenic sources of air pollution and primarily associated with the combustion of fossil fuel. Coal-fired thermal power plants and industrial fuel-burning plants that emit large quantities of nitrogen oxides (NО and NО2), solids (ash, dust, soot), as well as carbon oxides, aldehydes, organic acids into the atmosphere pollute the environment in majority. In the present work, a mathematical model and a scheme for calculating the formation of nitrogen oxide has been developed. Also, the dependence of the rate of release of fuel nitrogen from coal particles at the initial stage of gasification and content of volatiles has been obtained. The main regularities of the formation of NOx at the initial section of the flame in the ignition zone of the swirl burner flame during the combustion of Ekibastuz coal have been revealed. Modern environmental requirements for the modernization of existing and the creation of new heat and power facilities determine the exceptional relevance of the development of effective methods and constructions to reduce emissions of nitrogen oxides, sulfur oxides and ash to 200, 300, and 100 mg/nm3 at a=1.4. The dust consumption in all experiments was kept constant and amounted to 0.042 g/s, as well as with the results of calculating the thermal decomposition of the Ekibastuz coal dust, the recombination of atomic nitrogen into nitrogen molecules, and the kinetics of the formation of fuel nitric oxide.
It was found that despite the presence of oxygen in Ekibastuz coal for gases Odaf=11.8 % in an inert atmosphere, nitrogen oxides are not formed
