Purpose: This study aimed to investigate the effects of different general anesthesia procedures on postoperative olfactory functions and olfactory memory.
Materials and Methods: This prospective study was conducted with 97 patients. Patients were divided into three groups based on anesthesia induction and maintenance technique: Group P (induction and maintenance with propofol), Group PS (induction with propofol, maintenance with sevoflurane), and Group S (induction with sevoflurane, maintenance with sevoflurane). Butanol threshold and olfactory identification tests were administered 30 minutes (min) before the operation (T1) and 30 min (T2), 8 hours (h) (T3) and 24 h (T4) after the operation.
Results: Butanol threshold values were increased at the T2 time point compared to baseline in all groups, which returned to baseline values at T3 only in Group P. There was a significant difference between Group P and Group S in terms of butanol threshold values at all time points except T1. When olfactory identification increased at T3 and T4 compared to baseline in Group P, there was a significant difference between T2, T3, and T4 time points in Group S, and between T2 and T3 time points in Group PS as compared to Group P.
Conclusion: Propofol only causes a temporary impairment in olfactory functions in the early period and does not alter olfactory memory.

Published: March 2023

Purpose: Infertility is described as unexplained when all of the tests of a basic infertility evaluation return within normal limits and present in 15% of infertile couples. Some studies indicate that there is an association between methylenetetrahydrofolate reductase (MTHFR C677T and A1298C) mutations and unexplained infertility in male or female grown adults. The objective of this study was to analyze the distributions of MTHFR’s C677T and A1298C genotypes in couples with unexplained fertility problems (UFP) and healthy controls.
Materials and Methods: Two common variants C677T and A1298C of the MTHFR gene were screened in infertile couples (n =60 for C677T polymorphism; n=62 for A1298C polymorphism) and controls from the Cukurova region of Turkey. C677T and A1298C mutations in the MTHFR gene were detected by the SNP analysis (Fragment analysis) kit of the multiplex PCR amplification/ligation products. Homocysteine levels (in serum) were determined by the human hcy ELISA kit and folate values were determined by the Beckman coulter Unicel DxI 800 chemiluminescence test kit at the Central Laboratory of Balcali Hospital in Cukurova University.
Results: In this study, an association between unexplained infertility and MTHFR C677T polymorphism was not found. However, we found an association between MTHFR A1298C polymorphism and males with UFP (%7) and controls (%19). A statistically significant difference was observed between the infertile and control groups regarding i) the folate and homocysteine values of MTHFR C677T heterozygous individuals; ii) the homocysteine values of the MTHFR C677T normal individuals; iii) the homocysteine values of MTHFR A1298C heterozygous, normal and homozygous individuals; iv) the MTHFR C677T heterozygous and normal individuals; v) the homocysteine values of MTHFR C677T normal individuals; vi) the folate values of the MTHFR A1298C heterozygous and normal individuals.
Conclusion: The etiopathogenesis of unexplained infertility remains largely unexplored. However, the relationship of the folate/homocysteine findings with the MTHFR polymorphisms under study is not clear. The results of our study support a relationship between the MTHFR A1298C polymorphism and male fertility problems.

Purpose: The purpose of this study was to evaluate the role of diffusion-weighted imaging (DWI) in evaluating tumor response to chemotherapy in stage III-IV lung cancer.
Materials and Methods: Chest and DWI were performed with 3T MRI before and after 3 courses of chemotherapy on 32 patients diagnosed with stage III-IV lung cancer. DWI were acquired with a b factor of 50, 400 and 800 s/mm using a single-shot echo-planar sequence. Histopathological types before and after chemotherapy were compared by measuring mean apparent diffusion coefficient (mADC) values on the basis of regression and progression groups.
Results: 32 cases, 7 (18.5%) were in the progression group (PG), and 25 (81.5%) were in the regression group (RG). mADC in the PG was 1.06±0.43 x 10ˉ³ before chemotherapy and 0.85±0.24 x 10ˉ³ after chemotherapy. mADC in the RG was 0.92±0.27 x 10ˉ³ before chemotherapy and 1.20±0.26 x 10ˉ³ after chemotherapy. There was a statistically significant difference between the mADC values in the PG and RG before and after chemotherapy. There was no statistically significant difference in mADC values before and after chemotherapy in small cell lung cancer (SCLC) tumor type in the PG . There was a statistically significant difference in mADC values before and after chemotherapy in SCLC and non-small cell lung cancer (NSCLC) tumor types in the RG and NSCLC tumor type in the PG
Conclusion: DWI and ADC measurements can be used in assessing response to treatment in malignant pulmonary tumors.

Authors: ÇİFTÇİ Rukiye , KURTOĞLU Ahmet , ÇELEBİ Kahraman Özgür 
Published: March 2023

Purpose: The aim of the study was to investigate the effect of electromyography biofeedback (EMG-BF), which in addition to conventional electrophysical therapy (EPT) commonly used in the symptomatic treatment of carpal tunnel syndrome (CTS), on motor parameters such as strength and reaction time and symptomatic functional parameters such as pain and function of the upper extremity.
Materials and Methods: Patients diagnosed with CTS were divided into two groups. The first group was the conventional EPT group only (control group, n=46 hands), and the second group was the group that received EMG-BF in addition to the conventional EPT treatment (research group, n=42 hands). The pain (VAS), hand grip strength (HGS), audio-visual reaction time (ART-VRT), and upper extremity disability (Quick DASH) of patients in both groups were assessed before and after the treatment program.
Results: After treatment, VRT, ART, HGS, and Quick DASH were significantly better in favor of the EPT +EMG- BF group. Before treatment, resting state (VASr), mobile state (VASm), and night state (VASn) VAS values were similar between the two groups. After training, the VAS -values were better in favor of the EPT +EMG- BF –group.
Conclusion: Although EPT applications provide effective results in the rehabilitation of CTS, EMG-BF applications together with EPT applications provide more meaningful results in the rehabilitation process.

Published: March 2023

The fruits of Momordica charantia (Bitter Gourd) are well known for centuries as a natural remedy for the treatment of various ailments. In this study, we aimed to explore the metabolites present in both varieties of small and big bitter gourds and to explore the multitarget mechanism of M. charantia in antiviral infection by utilizing network pharmacology. The study design involves the identification of the compounds in both varieties of the bitter gourd by Agilent QTOFLC-MS/MS system, followed by screening for ADME to analyze the possible mechanism of action, disease association, protein-protein interactions and major pathways involved therein. Several Databases used were IMPAT, BindingDB, Swiss Target Prediction, STRING, DAVID, and KEGG databases, and algorithms were used to gather information. To visualize the network, Cytoscape 3.2.1 was used. As a result, a total of 22 and 27 compounds were detected from small and big bitter gourds respectively. . The molecules from M.charantia provide an antiviral response through the involvement of pathways like toll-like receptor pathway, PI3/AKT pathway, NF-kappa B signalling pathway, and cytokine-cytokine receptor interaction. Moreover, the core target genes termed ‘Hub Genes” were also identified through Cyto-hubba. The main mechanisms of M. charantia were acquired by investigating the enrichment of each cluster through functional association clustering analysis. Our results exposed the mechanism of M. charantia against viral infection by multi-component, multi-target, and multi-pathway study combinations.
Sobre la causalidad de los gastos deducibles para efectos del impuesto a la renta. Un enfoque empresarial
Authors: Santiváñez Guarniz Juan 
Published: March 2023

Las normas tributarias del impuesto a la renta señalan que para que un gasto sea deducible de impuestos debe cumplirse con el principio de causalidad; además señalan dichas normas que los gastos deben ser necesarios para generar renta y cumplir con criterios de razonabilidad del gasto, generalidad, entre otros.Demostrar que un gasto es necesario es una tarea compleja que en la mayoría de los casos obligará —a la persona que quiera determinar esa necesidad— a evaluar aspectos internos de las empresas, como estrategias empresariales, políticas internas, entre otros. Además de la complejidad analítica de esos temas, subsistirá siempre el aspecto subjetivo de parte del evaluador.Este artículo propone precisamente esa dificultad en demostrar si un gasto es necesario o no, a través del análisis de un caso real donde la Administración Tributaria objeta los gastos de un contribuyente por no considerarlos necesarios para el giro del negocio.

Environmental Accounting in Peru: A Proposal Based on the Sustainability Reporting in the Mining, Oil and Gas Industries
Authors: Tanaka Nakasone Gustavo 
Published: March 2023

This paper proposes an environmental accounting system in Peru that will improve the sustainability reporting of Peruvian corporations and have a positive impact on all the stakeholders (communities, stockholders, government, NGOs, etc.). This new environmental accounting system will allow companies to properly quantify and report environmental issues and have a more integral assessment and analysis of all the variables which affect their triple bottom line.Moreover, environmental issues in Peru will be partially solved when companies adhere to accurate measurement rules, timely submission of data, and fulfillment of government regulations. The principle behind the proposal is that accurate measurement, calculation and reporting on pollution levels will improve the ways companies address environmental and social issues, as well as enhance their financial results. This paper focuses on companies of the mining, gas and oil sectors, since they are arguably some of the main contributors to Peru’s GDP, as well as some of the nation’s largest polluters.

Micro-CT constitutes a valuable tool in assessing the impact of cordon constriction on the vascular morphology of grapevines
Authors: O'Brien Patrick , De Bei Roberta , Collins Cassandra 
Published: March 2023

The impact of permanent cordon training systems on the vasculature of grapevines has to date, not been investigated in depth. This study used optical microscopy (stereo microscope) and X-ray microtomography (micro-CT) to quantify the morphological properties of the xylem conduits of cane samples collected from the distal region of cordons, which had been established using four different training techniques. These treatments included one system where the cordon was wrapped very tightly around the cordon wire, a practice that is common in Australia and some other countries. The study also used micro-CT to observe the cordons directly, providing clear insight into the effects of the training methods on the localised structure of the cordons themselves. While the cordons in this study were only four years old at the time of their scanning and 3D reconstruction, significant differences were found between the different training methods. At one of the two trial sites, cordons which were wrapped tightly around the cordon wire had a significantly lower xylem conduit volume in relation to total cordon volume than those which had been woven through a plastic clip system centred between parallel cordon wires. The xylem conduits of woven cordons, in turn, had a lower volume than those which had been trained on top of the cordon wire and secured in place with plastic ties. Cordons which had been wrapped tightly around the cordon wire also had significantly thinner vessels and fewer connections per unit volume between vessels than other treatments at this site, as well as a lower theoretical specific hydraulic conductivity (Ks). No definitive patterns of differences between treatments were observed in the morphological properties of cane samples, either by stereo microscope or micro-CT. The results of this study suggest that the choice of cordon training method may have a notable impact on the capacity of the xylem for normal hydraulic function. Training methods which constrict the vasculature of the cordon, in particular tightly wrapping the cordon around the cordon wire, may have long-term negative outcomes on cordon health and productivity.

Published: March 2023

Abstract
The output torque of engine, propeller and other power sources in the operation process contains multi harmonic fluctuation components, which constitutes the main source of torsional vibration of shafting, and stimulate other vibration coupled with torsional vibration. This paper introduces a new method to solve torsional vibration of shafting system based on the line spectrum active control. It mainly includes: multi-body dynamic analysis model to reveal the coupling characteristics of torsional vibration and vibration in other directions; Aiming at the characteristic that the multi-harmonic vibration active control system for complex shafting systems may be equipped with several actuators, a new cross-coupled multi-channel line spectrum active control algorithm is proposed; A new type of torque actuator, the internal electromagnetic structure contains a relatively rotating stator and rotor. They are connected with springs. The whole can rotate with the shafting. The dynamic torque is issued according to the command of the active control system, in order to suppress the torque fluctuation due to the power sources, and greatly reduce the torsional vibration of the shafting.
Prediction of radioactive materials distribution from a hypothetical accident in Akkuyu NPP
Authors: Abbasi AKBAR 
Published: March 2023

Abstract
The Akkuyu nuclear power reactor (NPP), a new power reactor in the Mediterranean sea coast, which the plant is scheduled to be operational by 2023. In this research, a Lagrangian particle dispersion model HYSPLIT 3.1 was used to predict air dispersion and sea-level deposition of radioactive elements released from a hypothetical accident at Akkuyu NPP. Nuclear Regulatory Commission (NRC) library data was used to compute the source term for this approach. The simulations indicated that volumetric concentration levels exceeding 8.9 E+5 MBq/m3 were observed after fifteen minutes before the accident. The maximum deposition value of 11 MBq/ m2 was found in 1 h intervals at 18 km in the east direction of the site. Also, the trajectory of particle position shows that about 76% of the particles are distributed in the less than 5000 m layers and 26% in the more than 5000 m layers in all simulation time. The TED calculation indicates that the maximum dose (9.8E+1 Sv) occurred in the first day of the accident in 0.5 km of the reactor.
A Pattern in Nucleon Number and a Nuclear Structure Model
Authors: Lin Jingfeng , Lin Guangyi 
Published: March 2023

Abstract
This paper presents a discovery of an interesting pattern in the nucleon number of certain even-even nuclides with the highest isotopic abundance, which can be expressed as A=S(S+1)-2. The variable S represents a parameter of a specific type of shell structure, and this pattern is particularly evident in the heavy nuclear region. The paper proposes a shell-type nucleon arrangement scheme that can match both the A=S(S+1)-2 and A=S(S+1) patterns and contain closed-shell arrangements with magic numbers including 2, (4,) 8, 14, 20, 28, 50, 82, 126, as well as combinations such as 26+30, 40+50, 72+108, 82+126, 92+146, 108+162, and 120+184. Furthermore, a toroidal helical wave orbital model is introduced that matches the resulting arrangement scheme and mutually supports it. The purpose of this paper is to provide new insights into the structure of the nucleus.

Published: March 2023

Abstract
The concept of evolutionary computation in computational science was taken from the natural process of biological evolution, and this further led to the development of more advanced evolutionary algorithms to optimise complex problems. It is known that recycling and reusing help increase any organisation’s profit and take away environmental burdens. In this research work, we use a genetic algorithm, one such evolutionary algorithm, to find a solution to a mathematically modelled complex transportation network and efficiently manage the reverse flow of used vehicle parts. The model was developed only after considering all processes that affect the management of the reverse flow network. The research work aided in identifying the needful amount of facilities to efficiently handle the reverse flow of materials and parts. The results indicate that the mathematical model can be efficiently used to manage the reverse flow of materials and used components, thereby improving recycling efficiency in the application domain.

Published: March 2023

Abstract
While deep learning is frequently applied in bioinformatics, it is mostly limited to problems where huge amounts of labeled data are present to train a classifier in a supervised manner. Here, we introduce Self-GenomeNet– a method that utilizes unlabeled genomic data to address the challenge of limited data availability through self-training, outperforming the standard supervised training, even when using ~10 times less labeled data.
