Published: February 2022

Introduction: The aim of this study was to investigate the anatomy and anthropometric analysis of the optic canal and surrounding structures in Cone-beam computed tomography images.
Materials and Methods: In this descriptive-analytical study carried out from Autumn 2020 to Summer 2020, CBCT images from 150 patients referred to a medical center in Tehran were selected. The shape and length of the optic canal, width of the midpoint of the canal, the dimensions of the orbital cavity and the distance between the optic canal and the nasal columella were measured. Data were analyzed using the t-test and one-way ANOVA analysis (p value < 0.05).
Results: shape of the canal on the right side was 64.7% funnel-shaped, 32% hourglass-shaped and 3.3% amorphous and on the left side, 64% funnel-shaped, 34.7% hourglass-shaped and 1.3% amorphous among individuals. The average canal length on the right side was significantly larger than the left side, but the mean width of the midpoint of the canal on the right side was significantly less than on the left side (p value < 0.001). The height of the orbital cavity on the right side was significantly shorter than on the left side (p value = 0.034), but the width of the orbital was not significantly different between the two sides (0.232). The distance between the nasion to the orbit end of the canal and the cranium end of the canal, as well as the distance between the nasal columella to the orbit end and the cranium end of the canal, were significantly longer in men than in women and also significantly less on the right side than on the left side (p value < 0.001).
Conclusion: Knowing the anatomy of the optic canal will help prevent unwanted complications.

Authors: Dündar Abdulrahim , Ipek Deniz
Published: February 2022

Introduction: The treatment for unstable intertrochanteric fractures in the elderly patient has always been controversial. The aim of this study was to compare the outcome of porous coated cementless mono-block long stem hemiarthroplasty (CPH) and proximal femoral nail (PFN) on unstable intertrochanteric femoral fracture in the elderly patients.   Methods: From March 2017 and March 2020, 132 elderly patients with unstable femoral intertrochanteric fractures were treated by CPH or PFN. 73 patients were treated using proximal femoral nail (PFN) and 59 were treated using hemiarthroplasty (CPH). Bleeding amount, weight training time, hospitalization time, Harris scores, one-year mortality, pre-existing disease and postoperative complications were analyzed. Results: The average follow-up time was 23.2 months in the CPH group and 22.9 months in the PFN group. No significant differences was found between the two groups in terms of demographic data. There was no significant differences between the two groups regarding the ASA score, pre-existing disease, postoperative complications, and revision surgery. The mean operation time and the average amount of blood loss were significantly higher in the CPH group (p<0.05). Conclusion: Both PFN and CPH are two satisfactory methods for treating the elderly with unstable IT fractures but in the CPH group, early postoperative mobilization and decreased dependency are the primary advantages.

El drama que desnudó el final de la Segunda Guerra, forzó la reintroducción del debate por la forma arquitectónica, más allá de una limitada ficción desapasionada y racional de la función. Cuando la función dejó de ser el patrón unitario contra el que comparar a los edificios modernos, críticos e historiadores debieron disponer de nuevos espejos: monumentalidad, el proceso de producción, el usuario, la ciudad, la forma, el genius loci, la Historia, la tradición o la cultura. En el siguiente artículo, se verificará la formulación de imágenes arquitectónicas como catalizadoras por caso, del concepto de finalidad en arquitectura pública, tal como ha querido ser presentada en torno del concurso de la sede definitiva de la Biblioteca Nacional en Buenos Aires de 1962, en cuya arquitectura, a un rasgo de organización eficiente y provechosa, se superpuso por la forma, un rasgo de carácter manifiesto, redundante y dramático- con el arrojo que presupone.
Genetic-based personalized nutrition in Hungary – is there a viable business model?
Authors: Farkas Noémi Dóra , Kiss Marietta
Published: February 2022

A move from population-based nutrition guidance toward personalized nutrition may offer a more effective strategy than before to improve dietary habits of citizens worldwide. However, a significant number of consumers are not willing to adopt the highest level of personalization, i.e., gene-based personalized nutrition. The purpose of this paper is to examine whether there is a viable business model for genetically based personalized nutrition services in Hungary, and what business model would promote a higher level of consumer acceptance of the new technology. As a first step, a systematic Internet search was conducted to gather personalized nutrition counselling services that meet four criteria: they are related to nutrition; show some level of personalization; offer a product or service; and use some kind of consumer information to personalize a product or service. The second step was an expert content analysis of the service providers’ websites to identify the nine elements of the Business Model Canvas, based in which business model archetypes were identified. We can conclude that the vast majority of services available in the Hungarian market are based on phenotypic information; gene-based personalized nutrition is only rarely found. Our results suggest that business models of the Hungarian market differ significantly from the models identified by previous research. Of the eight identified business model archetypes, the “All in one place” model would promote a higher level of consumer acceptance of nutrigenomics-based services.

Opportunities for wastewater heat recovery in Hungary and its role in the circular economy
Authors: Gabnai Zoltán , Németh Kornél , Péter Erzsébet , Sertolli Ardit , Pestisha Albiona , Mezőfi Nóra , Bai Attila
Published: February 2022

Most of the energy content of wastewater can be found in wastewater heat, however, its recovery is limited. In this article, the current situation, future opportunities of wastewater heat recovery are presented based on secondary data collection, mentioning the constraints and main influencing factors of sustainable implementation of heat recovery systems in Hungary. Besides, the already existing systems are described. As regards the capacities of treatment plants, 103 of the 574 domestic plants have a capacity of over 20,000 Population Equivalent (PE), of which 25 plants have a capacity of over 100,000 PE. According to our calculations, in big cities/capitals (20.000 – 100.000, and over 100.000 inhabitants), it may be possible to recover wastewater heat sustainably in several places. In small towns (5.000 – 20.000 inhabitants), wastewater heat recovery can be technologically and economically sustainable only in the presence of agricultural or industrial plants with high and continuous wastewater feed into the pipeline system. Taking into account the temperature conditions at each place of use and their estimated fluctuations, it can be said that proper, careful planning, sizing and implementation have a crucial effect on the efficiency of microbiological activity in the treatment plants. In bigger cities, of course, the effect of the temperature drop of one main collector may be minimal, however, in smaller and medium-sized settlements, excessive heat extraction may result in complete inhibition or cessation of nitrification. In Hungarian case studies, the maximum acceptable temperature drop is approx. 2-3 °C. It can be stated that energy recovery from wastewater may be very promising considering the size and temperature limitations. Therefore, the rational recovery of wastewater heat can be an important part of the implementation of circular economy and sustainable energy utilization in wastewater management, resulting in significant energy savings and pollutant reduction.

Exploring livelihood strategies of herder households in Mongolia: income-based approach
Authors: Gombodorj Ganchimeg
Published: February 2022

The classification of livelihood strategies is important for identifying different lifestyles and developing poverty reduction measures. The research was aimed to identify Mongolian herder households’ livelihood strategies and assess capital factors that impact their choice and livelihood outcomes in connection with wealth and poverty. A total of 350 herder households were surveyed using the stratified sampling methods from four different economic regions. The Income-Based Approach was applied to identify herder households’ livelihood strategies based on their primary income sources and Pearson correlation was used for assessing the influencing input. The study hypothesizes that herder households earn the majority of income sources from animal husbandry and an essential factor in the choice of livelihood strategy is the number of animals. The study found that livelihood strategies of nomadic herder households clustered into four main types: а) livestock income sources, solely b) earn from kinship and assistant herder salary in addition to livestock income; с) social benefits and pension income in addition to livestock income and d) income sources dependent on natural resources in addition to livestock income. Location, financial capital, and physical capital were the main factors for choosing a specific livelihood strategy. There was an insignificant difference between poor and wealthy herder households in terms of physical assets ownership. To reduce rural poverty, we need tailored sustainable development policies based on different herder households’ livelihood strategies.

Authors: Olanike Alawode Olubunmi , Lekan Makinde Olumuyiwa
Published: February 2022

Nigeria is experiencing a gradual shift from subsistence to commercialized agriculture, thereby increasing involvement and activities at different nodes of agribusiness. Participation of farmers in markets is an important determinant of well-being and development, and one of the pathways towards economic growth. This study analysed household crop commercialization in Nigeria. The secondary data used were the General Household Survey (GHS, 2018) Wave 4. Data were analysed using descriptive statistics, household crop commercialization index (HCCI) and ordered probit regression model.

Mean age of Nigerian farmers was 50.04 years (±15.22), majority (85.68%) were male, married (82.51%), and 72.14% had formal education. Farming is viable in all the geopolitical zones and majority (87.64%) of the farmers were from the rural sector, holding a mean total plot size of 12.61(±15.63) hectares, and planted 3 crops on the average. The most produced crop categories are cereals (46.75%), tubers (20.70%) and legumes (19.00%); legumes and cereals are highest in the North, and tubers in the South. Subsistence households were 32.81% (HCCI=0), only 1.71% of the households were fully commercial (HCCI=100), while semi-subsistence households (0≤HCCI≤100) constitute 65.48%. Years of education (p<0.05) and crop production in North East and North West zones (p<0.01) constrain commercialization, while at p<0.01, crop production in the rural sector and the South zones, and increased land holding are the drivers of household crop commercialization in Nigeria.

Nigerian farming households are mainly semi-subsistence and are diversified in crop production. Nigeria relies more on market participation of the semi-subsistence households, through their marketable surplus, to feed her teeming population and for exports. Further attention on rural infrastructure development in all geopolitical zones and awareness creation on producing market oriented products will increase agribusiness activities. This will generate green decent jobs that will take unemployed youths off the streets of urban centres. This is in tune with the economy diversification bid and the new Nigeria Economic Sustainability Plan of the Federal Government of Nigeria.

Authors: Nagy Orsolya Bernadett
Published: February 2022

The aim of the study is to compare the preferences for the purchase and consumption of industrially kept pigs and mangalica pigs. The research was conducted among the students of the Faculty of Economics and Business of University of Debrecen in October 2019, in the form of an online questionnaire. Descriptive statistical methods, chi-square tests, Spearman rank correlation indexes, factor analysis and two-step cluster analysis were used to analyze the data obtained from the survey. Based on the results, it can be said that there are differences in consumer perceptions of industrially kept pigs and mangalica pigs among a number of sociodemographic factors. Factor analysis was used to delimit three factors in the case of industrially kept pigs (“domestic-branded-fresh product” aspects, factors related to health awareness, aspects of a marketing nature), while in the case of mangalica pigs one factor was identified. Next, I used a two-step cluster analysis using the isolated factors, where several sociodemographic variables were tested. The best fit was shown by the combination of gender and highest educational level. Based on these, it can be concluded that in the case of industrially kept pigs, the factors considered in the purchase were the most important for women and men with higher education in the case of two factors (“domestic-brand-fresh product” aspect and marketing aspects) and for mangalica pigs. While in the case of industrially kept pigs, the third factor (factors related to health awareness) that were taken into account in the purchase proved to be the most important for men with a secondary education.

situation of agricultural sector in Hungary – trends and territorial aspects
Authors: Molnárné Barna Katalin , Molnár Tamás , Koczor-Keul Melinda
Published: February 2022

Based on its geographical features, Hungary is basically an agricultural country. The proportion of the production area within the total area of the country is approximately 80% and the proportion of arable land is 60%. This makes our country one of the first in the European Union. In the EU, only Denmark and the United Kingdom have a higher proportion of agricultural land. Hungary accounts for only 3% of the total agricultural area of ​​the EU-27 Member States, however, it plays a significant role in the production of certain products. (Harangi-Rákos, 2013)

In addition, the climate is favorable for agricultural production, which also strengthens the country's agricultural character. Throughout history, we have rightly been given the honorable name “pantry” (Marosi, 2009), which was true both within the Monarchy and Europe. In the socialist system the agricultural country became a so-called “industrial-agrarian” country due to the violent industrializations.

Beyond industrial development, the service sector plays an important role in the national economy due to its technology-intensive nature. In addition, agricultural production is still significant in Hungary (Lakner et al. 2020). The agricultural sector is significantly involved in the production of the gross domestic product (Fróna-Kőmíves 2019) and in the positive development of the export-import balance. During the 2008 world crisis, it was thanks to this sector, among other factors, that the recession that affected our country did not deepen. The domestic consumption is largely covered by domestically produced commodities (Csatáriné, 2019)

Our results show that China's demand for large-scale market and for opening to the outside world as well as Kazakhstan’s great energy potential are the most important factors their cooperation. It can be stated that in our days Kazakh legislation is suitable for promoting the Chinese energy investments, but in the long run it would be beneficial to mobilize national capital especially in RES investments and research. In the end, we found the most important reserves in competitiveness of electricity and heat (both from fossil and renewable energy sources) are power grid consolidation and waste heat utilization in the short run.

Treatment modalities for hepatocellular carcinoma (HCC) vary from surgical techniques and interventional radiologic strategies to systemic therapy. For the latter, the use of immune checkpoint inhibitors (ICIs) has gained popularity due to successful trials showing increased survival. In patients who have undergone liver transplantation, recurrence of HCC poses a significant challenge. There is indeed considerable debate on the efficacy and safety of ICI use in liver transplant recipients due to competing immune interests in maintaining a healthy graft and combating the tumor. Recent reports and case series have highlighted a role for the type of immune therapy, timing of therapy, tissue expression of PD-1 and modulation of immunosuppression, in the understanding of the efficacy and risks of ICIs for HCC in liver transplant. In this article, we appraise the available literature on the usage of ICIs for HCC in liver transplant recipients and provide perspectives on immune concerns as well as potential recommendations to consider during the management of such complex cases.

Aim: Genetic polymorphisms of human leukocyte antigen (HLA) class II molecules are associated with chronic hepatitis B virus (HBV) infection. We aimed to investigate the impacts of HLA-II haplotypes on viral evolution and the risks of HBV-caused liver diseases. Methods: HLA-DR-DQ-DP haplotypes were estimated in 1210 healthy controls, 296 HBV clearance subjects, 301 asymptomatic hepatitis B surface antigen carriers, 770 chronic hepatitis B patients, 443 HBV-related liver cirrhosis (LC) patients, and 1037 HBV-related hepatocellular carcinoma (HCC) patients. HBV mutations were determined by sequencing. The associations of HLA-DR-DQ-DP haplotypes with viral mutations and the risks of liver diseases were assessed by multivariate logistic regression. Results: Compared to HBV-free subjects, the haplotypes CCAACG, CCGACG, TCAATA, and TCGATA were associated with decreased HCC risk, with an odds ratio (OR) [95% confidence interval (CI)] of 0.62 (0.40-0.95), 0.60 (0.39-0.92), 0.73 (0.54-0.98), and 0.58 (0.42-0.78), respectively. CCAACG, CCGACG, and TCAATA were significantly associated with decreased frequencies of the HCC-risk HBV mutations: preS1 deletion, APOBEC-signature HBV mutations in the core promoter and preS regions, A51C/T, G104C/T, and G146C/T. TCGATA and TTAACG were associated with increased LC risk, with an OR (95%CI) of 1.54 (1.03-2.30) and 2.23 (1.50-3.33), respectively. However, TCGATA and TTAACG were not consistently associated with the cirrhosis-risk HBV mutations. Conclusion: CCAACG, CCGACG, and TCAATA are inversely associated with HCC risk, possibly because they are involved in creating an immune microenvironment attenuating the generation of HCC-risk HBV mutations. TCGATA and TTAACG might predispose the polarity of immunity towards Th17 isotype related to LC.

Recently, a rising use of wireless internet technologies has been demonstrated. The devices 18 which use these technologies emit in new spectral regions an electromagnetic radiation (EMFs) 19 which could interact with the male reproductive system. The aim of this study was to investigate in 20 vitro influence of electromagnetic fields at 27 GHz on sperm quality in Mytilus galloprovincialis. 21 Sperm samples, were collected from sexually mature males of M. galloprovincialis and placed in sea- 22 water. Once evaluated the number and quality of spermatozoa, sperm cells were exposed to elec- 23 tromagnetic fields radiated by a pyramidal horn antenna. The effect of exposure was evaluated after 24 10, 20, 30,40 and 60 minutes with light microscope and using Eosin test. Ten replications were per- 25 formed and statistical analysis was carried out by one-way ANOVA test. A significative decrease 26 in sperm motility was observed after 10 minutes of exposure and after 30 minutes most of sperms 27 were immobile and not vital. This study provides useful data on potential ecological impact of the 28 5G high-band on animal fertility, whose effect is currently under investigation.
Human Muscle Spindles are Wired to Function as Controllable Signal-processing Devices
Authors: Dimitriou Michael
Published: February 2022

Muscle spindles are encapsulated sensory organs found in most of our muscles. Prevalent models of human sensorimotor control assume the role of spindles is to reliably encode the mechanical state of muscle i.e., muscle stretch. Here, I argue that the traditional view of the spindle as a basic mechanoreceptor is outdated. Spindle organs can be independently tuned by spinal γ motor neurons that receive top-down and peripheral input, including from cutaneous afferents. I propose that spindles under efferent control play a flexible and higher-level role, providing a unique service to the nervous system: that of a peripheral signal-processing device that helps augment and expedite sensorimotor performance. Recent studies with naturalistically active humans support such a role, showing that spindle tuning enables the independent preparatory control of muscle compliance, the selective extraction of information during implicit motor adaptation, and for segmental stretch reflexes to operate in joint space. A new model of human sensorimotor control is presented, viewing γ motor activity as an intermediate coordinate transformation that allows different descending and peripheral information to project onto a common spindle-based coordinate frame. Incorporation of advanced signal-processing at the periphery may well prove a critical step in the evolution of sensorimotor control theories.
Estimating the Best Exponent of the Modified Universal Soil Loss Equation and Regionalizing the Modified Universal Soil Loss Equation under Hydro-Climatic Condition of Ethiopia

Soil erosion and sediment transport are quite complex processes as they depend on physical, biological, mechanical, and chemical processes within a particular catchment. Therefore, it is highly essential to better explain engaged physical processes and means of accounting for site-specific conditions, for soil loss and sediment yield estimation. This paper mainly focuses on physical explanations behind erosion and common erosion models like Universal or Revised Universal Soil Loss Equation(USLE/RUSLE) and Modified Universal Soil Loss Equation(MUSLE). Based on the physical explanations and overall limitations, the MUSLE is selected for the application of sediment yield estimation. To regionalize the MUSLE, the main parameters of the MUSLE which directly affect the erosion process such as cover, conservation practice, soil erodibility, and topographic factors are estimated based on the past experiences from literature and comparative approaches, whereas the other parameters which do not directly affect the erosion process or which do not have physical meaning (i.e coefficient a and exponent b ) are estimated through calibration. The best exponent (b) of the Modified Universal Soil Loss Equation is 1, which results in Nash-Sutcliffe efficiency of approximately 1. The regionalized MUSLE shows good performance for all four watersheds under our consideration and we expect the same for other watersheds of Ethiopia.
Redox Homeostasis and Nitro-Oxidative Stress in Obesity-Linked Inflammation
Authors: Bottari Serge P , Di Tommaso Margaux , Samouda Hanen
Published: February 2022

It is now well accepted that most chronic diseases have a common feature which is “low-grade” inflammation. Whether inflammation is causal or rather consequent to these diseases is still a matter of debate. A key factor of inflammation is considered to be “oxidative stress”, which is the result of an alteration of redox homeostasis which is critical for the regulation of physiological cell and organ metabolism and proliferation. The term “oxidative stress” is how-ever often used in an inappropriate manner as the primary target of the initial oxidative radical, superoxide ion, is nitric oxide which, being in large excess, acts as a “buffer”, yielding reactive nitrogen species. It is only once the superoxide fluxes exceed the nitric oxide fluxes that true “oxidative stress” occurs. Nitro-oxidative stress is a more appropriate term which takes into account the evolving generation of reactive nitrogen and oxygen species and their effects on cell and organ pathophysiology. The molecular bases of redox homeostasis and nitro-oxidative stress will be presented and discussed using obesity-linked inflammation as a path-ophysiological example.

Published: February 2022

Background. We aimed to assess the validity of the Mat-O-Covid Job Exposure Matrix (JEM) on SARS-CoV2 using compensation data from the French National Health Insurance compensation system for occupational-related COVID-19. Methods. Deidentified compensation data for occupational COVID-19 in France were obtained between August 2020 and August 2021. The acceptance was considered as the reference. Mat-O-Covid is an expert based French JEM on workplace exposure to SARS-CoV2. Bivariate and multivariate models were used to study the association between the exposure assessed by Mat-O-Covid and the reference, as well as the Area Under Curves (AUC), sensitivity, specificity, predictive values, and likelihood ratios. Results. In the 1140 cases included, there was a close association between the Mat-O-Covid index and the reference (p<0.0001). The overall predictivity was good, with an AUC of 0.78 and an optimal threshold at 13 per thousand. Using Youden’s J statistic resulted in 0.67 sensitivity and 0.87 specificity. Both positive and negative likelihood ratios were significant: respectively 4.9 [2.4-6.4] and 0.4 [0.3-0.4]. Discussion. It was possible to assess Mat-O-Covid’s validity using data from the national compensation system for occupational COVID-19. Though further studies are needed, Mat-O-Covid exposure assessment appears to be accurate enough to be used in research.
