Published: May 2021

The first reports of hypersensitivity reactions following the rollout of COVID-19 vaccination programs have raised public concern. Given the recent availability and novel mechanisms of COVID-19 vaccines, there is limited data on possible hypersensitivity reactions. Although it seems rare, the incidence of anaphylaxis for approved COVID-19 vaccines has been suggested as being higher when compared to previous vaccines. Adequate risk assessment, recognition, classification, and management of hypersensitivity reactions is crucial to ensure safe immunization and avoid misinformation and vaccine hesitancy. In this review, we present an overview of the types of hypersensitivity reactions that can potentially occur due to vaccination and the possible allergenic components of COVID-19 vaccines, as well as a suggestion for causality and risk assessment for the BNT162b2, mRNA-1273 and AZD1222 vaccines.

Published: May 2021

Background: The COVID-19 pandemic has made people spend more time on online meetings more than ever. The prolonged time looking at the monitor may cause fatigue, which can subsequently impact the mental and physical health. A fatigue detection system is needed to monitor the Internet users well-being. Previous research related to the fatigue detection system used a fuzzy system, but the accuracy was below 85%. In this research, machine learning is used to improve accuracy.Objective: This research examines the combination of the FaceNet algorithm with either k-nearest neighbor (K-NN) or multiclass support vector machine (SVM) to improve the accuracy.Methods: In this study, we used the UTA-RLDD dataset. The features used for fatigue detection come from the face, so the dataset is segmented using the Haar Cascades method, which is then resized. The feature extraction process uses FaceNet's pre-trained algorithm. The extracted features are classified into three classes—focused, unfocused, and fatigue—using the K-NN or multiclass SVM method.Results: The combination between the FaceNet algorithm and K-NN, with a value of  resulted in a better accuracy than the FaceNet algorithm with multiclass SVM with the polynomial kernel (at 94.68% and 89.87% respectively). The processing speed of both combinations of methods has allowed for real-time data processing.Conclusion: This research provides an overview of methods for early fatigue detection while working at the computer so that we can limit staring at the computer screen too long and switch places to maintain the health of our eyes.

SPECIFICS OF FORECASTING METHODOLOGY INDUSTRIAL INJURIES AND PROFESSIONAL DISEASES
Authors: POLUKAROV Yury , ZEMLYANSKA Olena , KACHYNSKA Nataliia , MITIUK Liudmyla
Published: May 2021

Purpose. Substantiate the need for development of new scientific and methodological foundations for forecasting occupational injuries and illnesses.

Methodology. Analyze existing methods of occupational injuries and illnesses forecasting, propose a new algorithm for calculation of their levels, set scientific and methodological requirements to information analysis system used for the prevention of occupational illnesses.

Findings. Modern methods of forecasting injuries make it possible to assess the effectiveness of preventive measures. However, there is no universal method for analyzing the occupational morbidity due to the different specifics of disease causes and manifestations which do not allow to conduct a realistic assessment of labor protection in a particular area over a given period of time. Therefore, it is the reduction in the level of occupational injuries and illnesses compared to the data obtained by the forecasting method that may be indicative of preventive measures effectiveness. At the same time, development of information analysis system of personal protective equipment continues to be a pressing issue (PPE).

Originality. It has been proposed to develop a special mathematical tool for determining loss reduction and information analysis system, which will provide a forecasted estimate of occupational morbidity at an enterprise. To obtain a reliable forecast it is important to identify the average value of cases over a given period of time, which has been considered in this paper.

Conclusions and Practical Significance. There are numerous methods available for analysis of occupational injuries and illnesses. Most of them, however, are unfit for the assessment of occupational diseases. Since chronic occupational illnesses have a cumulative nature, the rate of work-related diseases is more predictable than that of injuries and accidents. This makes it possible to determine the “occupational morbidity rate” provided that the time spent by workers in the area of exposure to occupational hazards is recorded together with reference data on the conditional level of exposure to each hazard.

Keywords: forecasting, injuries, occupational morbidity, occupational safety activities, hazard, information analysis system.
The quality of air transport services in function of improving the total quality of tourism offer
Authors: Prebežac Darko
Published: May 2021

Growing rivalry among competitive airlines in the air travel market, appearance of new competitors which of course have been located in the profitable parts of the market, changes in the behaviour of potential passengers, insufficient and therefore high-priced airport and air traffic control infrastructure, as well as the increased competition of the alternatives to the air transport such as telecommunications media and super-last trains, characterise the present competition in the air transport market. Significant changes in behaviour of potential users of airline services have appeared on the side of air transport service demand, and the airlines themselves have less and less influence on distributions channels. The result of it are the increasing price-pressure and considerable decrease of passengers loyalty. Due to the increase of travel intensity passengers have become more experienced and critical in quality estimation of offered service as well as in checking whether the price of service corresponds to its quality. This has forced airlines to adapt permanently to new and more demanding passenger requirements. Those airlines which are not able to follow cost decreasing trend are obliged to improve their own competitive position looking for the reserve in other business fields. This is the only way of surviving in their fight for passengers. Therefore, the quality of air transport service plays an increasing role in the development of their competition capability. Since tourism offer consists of different kind of products and services, air transport service being one of them, it is of utmost importance that all of them meet to a maximum degree with passengers quality requirements, hi such manner passengers will get an impression that it is a question of an unbroken chain making a total quality concept of services they have expected, companies will capitalise money and time they have spent in developing service quality and improving their own productivity, and tourist industry will be able to respond to the most recent market challenges in a more adequate way.

Authors: Šimundić Borislav , Lovreković Damir
Published: May 2021

Rapid growth of tourism industry in Croatia has had an impact upon the national passenger and cruise fleet so that, according to statistical data, by 1989, the coastal regions and the islands of Croatia were visited by 7.8 million tourists (58 million bed nights). Parallely with the development of passenger shipping industry, which also reflected the rise of shipbuilding industry and tourism in Croatia, catering activities on liner and cruise ships have recorded an upward trend. In this context, passengers were provided with basic catering services on short routes and with a more complete and sophisticated culinary service on longer coastal and international cruising routes. Passenger and cruise catering , is part of catering business activities on various means of transportation, aiming to meet passenger needs and requirements within the larger framework of various services generally provided on board ships. Passenger shipping companies regard catering services and activities on board their ships as an accessory yet indispensable component making part of their principal activities, i.e. carriage of passengers and goods by sea. This paper deals with the management and quality of catering services on board ships owned and operated by Croatian largest passenger shipping company "Jadrolinija" Rijeka and reflects many specific features and a critical analysis in this domaine.

Tourism: the connection of the original and the modern
Authors: Vlahović Darko
Published: May 2021

Some people, in order to succeed in the tourist business, emphasize today the importance of regulating and implementing certain standards, as if to avert the doubt in the quality of satisfying tourist requirements. On the other side, the development trend towards "experiencing type" of tourism is emphasized, where emotional value of the tourist stay is at the centre of attention, i.e. a holiday with a purpose. Taking into consideration all difficulties and disproportions, necessary changes are the condition for a newtourist future in Croatia, However, it is necessary then to find a balance between "old" values and the modem way of doing business, with a right concept of development. The author investigates in this sense the necessity of accepting that invisible thread between the traditional and the modem, and their constant permation. He pleads for a creative application of foreign experience and not for a simple copying. Croatia needs positive ideals but without neglecting the possibilities of its own creative spirit and without interrupting the connections with its own tradition. Globalization as a process is a great challenge for Croatian tourism offering chances but also bringing dangers. Development and innovative changes in the field of tourist facilities should, therefore, be directed towards the co-existence of modem rationality and traditional hospitality, discovering and encouraging specific identity in order to offer readily our own values and the richness of our own tradition. Consequently, all these elements should be put into balance as a harmony of the new and the old in shaping tourist facilities and their functioning.

Authors: Vuković Ivan
Published: May 2021

Modern trends in the development of European tourism, especially in the north-western European countries, characterise a permanent increasement of tourism and a demand for new tourist destinations, which provide quality tourist services. In this context, the importance for development of Croatian tourism is as one of the biggest European tourism countries. In this research we tried to investigate modem trends in the development of European tourism, as well as the influence of economical, social and political development on development of tourism. These trends in European tourism have repercussions on the possibility of development of Croatian tourism, with condition of changing the structure in hotel and tourism economy. We must have the high standards of services in our hotels, so we should integrate with the European Union.

Published: May 2021

Female sexual functioning and satisfaction are impaired by the presence of sexual difficulties. Current study aims to analyze the differences on sexual satisfaction in women according to types of sexual problems (absence of sexual problems, self-perceived and assessed by the FSFI cut-off). A total of 329 women answered to a specific question about presence of self-perceived sexual problems, the Sexual Satisfaction Scale for Women, and the Female Sexual Functioning Index. Main findings revealed that sexually health women had better levels of sexual satisfaction when compared to women who self-report sexual difficulties and women who scored clinical levels in FSFI. Also, women who scored clinical levels in FSFI scored lower on sexual satisfaction compared to women who self-report sexual difficulties. Female sexual satisfaction was negatively affected by sexual difficulties assessed according to the FSFI cut-off. Although with lower impact, self-perceived sexual problems also affect negatively sexual satisfaction in women.

Analizar la implementación de dos políticas públicas para el sector rural en la nueva administración pública federal bajo el enfoque del ciclo de políticas públicas. De 2017 a 2019 se realizó un estudio en 24 comunidades de 6 estados del país, los resultados reflejaron la dispersión de recursos en más de 100 programas; en las comunidades estudiadas, los beneficiarios solo recibían dos o tres de ellos. En el nuevo sexenio se ha percibido la falta de información precisa sobre el acceso a los programas, en la opinión pública no se percibe un diseño y planeación de políticas que impacten de manera concreta en el fomento productivo; se continúa y profundiza en políticas de transferencias y fomento social. Se concluye que continúa un esquema similar al anterior gobierno en la definición e implementación de políticas públicas para el campo.
Causalidad mediada: un modelo contemporáneo de coerción social
Authors: Giromini José Gabriel
Published: May 2021

El propósito de este artículo es avanzar un modelo plausible de causalidad social, que llamamos de causalidad mediada.La primera parte del artículo se dedica a introducir algunas distinciones conceptuales básicas que definen los parámetros del modelo: qué tipos de entidades sociales ejercen qué tipo de coerción y sobre quiénes. La segunda parte avanza la estructura general del modelo que proponemos, explicando en qué sentido puede considerarse un modelo de causalidad y en qué sentido esa causalidad es social. Como resultado, el modelo define dos condiciones que deben satisfacerse para que se produzca un episodio de causalidad social mediada: (1) un individuo I consigue que otro, independientemente de su voluntad, produzca un comportamiento determinado (2) I lo consigue en virtud de la presencia de entidades tales como prácticas, posiciones y relaciones sociales.

Published: May 2021

The academic performance of engineering students continues to receive attention in the literature. Despite that, there is a lack of studies in the literature investigating the simultaneous relationship between students' systems thinking (ST) skills, Five-Factor Model (FFM) personality traits, proactive personality scale, academic, demographic, family background factors, and their potential impact on academic performance. Three established instruments, namely, ST skills instrument with seven dimensions, FFM traits with five dimensions, and proactive personality with one dimension, along with a demographic survey, have been administrated for data collection. A cross-sectional web-based study applying Qualtrics has been developed to gather data from engineering students. To demonstrate the prediction power of the ST skills, FFM traits, proactive personality, academic, demographics, and family background factors on the academic performance of engineering students, two unsupervised learning algorithms applied. The study results identify that these unsupervised algorithms succeeded to cluster engineering students' performance regarding primary skills and characteristics. In other words, the variables used in this study are able to predict the academic performance of engineering students. This study also has provided significant implications and contributions to engineering education and education sustainable development bodies of knowledge. First, the study presents a better perception of engineering students' academic performance. The aim is to assist educators, teachers, mentors, college authorities, and other involved parties to discover students' individual differences for a more efficient education and guidance environment. Second, by a closer examination at the level of systemic thinking and its connection with FFM traits, proactive personality, academic, and demographic characteristics, understanding engineering students' skillset would be assisted better in the domain of sustainable education.

STAR AND POOR FUND PHENOMENA IN ISLAMIC- AND CONVENTIONAL-FOCUSED FAMILIES: EMERGING COUNTRY EVIDENCE
Authors: Bani Atta Anas Ahmad , Marzuki Ainulashikin
Published: May 2021

The aim of this study is to investigate star and poor phenomena and their impact on the flows of Islamic-focused family (IFF) and conventional-focused family (CFF). The sample includes the four emerging countries with the largest number of Islamic mutual funds from 2007 to 2018 (Saudi Arabia, Malaysia, Indonesia, and Pakistan). Panel regression analysis was used to examine the impact of dummy star and poor as independent variables, and family age, size, number of funds, past returns, and total risk as control variables for fund family flows. The results show that the dummy star has a significantly positive relationship with family flows. Family managers have succeeded in attracting more investors by using the strategy of advertising the best performing funds. However, in both, all families and IFF, the dummy poor has a negative relationship, but is insignificant. On the other hand, for CFFs, the dummy poor is significantly negative. This is because investors in IFFs, unlike those in CFFs, have more loyalty due to their moral and religious goals in addition to traditional goals. The novel finding of the study is the difference in the star phenomenon between the IFF and CFF. The findings are important for managers, as they will help them to create appropriate strategies to attract more flows and increase the assets under their management. In addition, the findings will help investors to direct their money to appropriate families.
EVOLVING MONETARY ECONOMICS IN ISLAMIC PERSPECTIVE
Authors: Ayub Muhammad , Khan M. Fahim
Published: May 2021

The challenges facing the Islamic banking and finance industry include, inter alia, resolving the issue of ‘form over substance’, adopting value-based social and ethical finance, and reinforcing public confidence that its business and services conform to the principles of Shari’ah in both letter and spirit. These challenges can be faced only if Islamic finance is based on the money and monetary perspective of Islamic economics. An important aspect for discussion in this context is the issue of money creation. This paper is based on an analysis of the literature on conventional and Islamic economics and Islamic finance. It comprises observational and narrative research mainly because monetary policy from an Islamic perspective has not been implemented in any jurisdiction in the modern world. Its objective is thus to suggest how monetary policy might evolve from the perspective of Islamic law of contracts. It discusses an economic model in which a new theory of monetary economics could become a basis for evolving Islamic finance in its value-based perspective. It also discusses monetary economics and monetary policy from an Islamic perspective in the context of contemporary Muslim economies. The Islamic financial system must be based on the Islamic system of money, monetary economics and exchange principles. Hence, economists and policymakers may first focus on evolving monetary economics and policy from an Islamic perspective, to serve as a basis for structural reforms.
Simulation of Effect of Force Chain on Graphite Migration of Copper Based Graphite Composites During Friction
Authors: Chen Kun , Xie Ting , Zhang Longxiao , Li Chen , Wen Heng , Meng Xiang
Published: May 2021

To further reveal the mechanism of graphite migration in copper based graphite composites sliding against 45 steel, the particle Flow Code in 2 Dimensions (PFC2D) was employed to simulate and analysis the relationship between internal force chain and graphite migration in the composites. The simulation results show that a migrated graphite particle layer is formed on the composite surface during friction, and maintains dynamic equilibrium relying on “self-consumption”. The graphite migration displacement to the friction surface is affected by the force chain. The greater the force chain strength is, the smaller the graphite migration displacement is. When the force chain angle is in the range of 75° to 95°, the migration of the graphite particles can not occur; when the angle is 95° to 135°, the graphite migration displacement increases with the increase of the angle. And the greater force chain strength corresponds to the less worn particles and the less migrated graphite particles. The simulation results are significant for optimizing material design and improving the friction performances of copper based graphite composites.

Published: May 2021

Background: We aim to analyze the clinicopathological features and outcomes among different histologic subtypes of HPV-independent endocervical adenocarcinomas（HPVI ECAs).Methods: Forty-five HPVI ECAs, including 16 minimal deviation adenocarcinoma (MDA), 17 non-MDA type of gastric adenocarcinoma (GAS), and 12 non-GAS HPVI ECAs were studied. Data of clinical features, pathological characteristics, treatment, and outcomes were evaluated. Results: The median age of patients with GAS was 46 years old (IQR: 41.5, 59.5), with no significant difference compared to patients with non-GAS HPVI ECA (48-year-old, IQR: 40.5, 60.5) (p=0.92). Compared with non-GAS HPVI ECAs, GAS hade more common complains of vaginal watery discharge (p=0.047). GAS cases were also associated with higher clinical stage at diagnosis (P=0.016), deeper cervical stromal invasion (p=0.01), and worse 5-year progression free survival (PFS) (p=0.032). Compared with non-MDA GAS, MDA had similar clinical and pathological features and prognosis. Of note, cytology results showed a lower positivity rate for HPVI ECAs (65.2% for GAS and 60% for non-GAS HPVI ECA), and MDA had a lower positivity rate than that for non-MDA (40.0% vs 84.6%, p=0.026). Serum CA19-9 levels were significantly higher in MDA than those in non-MDA (184.5 U/ml vs 22.4U/ml, p=0.045) and non-GAS cases (184.5U/ml vs 10.6U/ml, p=0.006).Conclusions: GAS HPVI ECA had different clinical presentation with genital watery discharge compared with non-GAS HPVI ECA cases. Comparison with those of non-GAS HPVI ECAs, GAS cases were more likely to have high risk pathological factors and poorer PFS. Serum CA19-9 may be helpful for diagnosis and screening in patients with GAS, especially those with MDA.
Design and Characteristics of a Novel QZS Vibration Isolation System with Origami-inspired Corrector
Authors: Liu Shiwei , Peng Gaoliang , Jin Kang
Published: May 2021

A new class of quasi-zero-stiffness (QZS) vibration isolation systems, inspired by the origami metamaterial, is proposed to achieve high-performance vibration suppression in this paper. According to the mechanical characteristics of Tachi-Miura origami (TMO) with single degree-of-freedom, the nonlinear geometric relationship is developed with the folding angle as the master variable. By utilizing equivalent transformation and virtual work principle, the static model is established, the influence of structural parameters on stiffness is investigated, and the negative stiffness mechanism of origami mechanism is revealed. By adding a linear spring with positive stiffness to the origami in parallel, the Tachi-Miura origami vibration isolator (TMOriVi) is obtained. Subsequently, the governing equation is presented by means of the harmonic balance method. Two types of instability situations, jump phenomenon and unbounded response, are studied, and their analytic criteria and relationship are derived. Finally, through the parametric influence analysis and a series of comparative studies, the effectiveness and superiority of the proposed isolator are verified. The proposed vibration isolation system with great design flexibility exhibits a significant potential in the field of low-frequency vibration isolation.

Published: May 2021

BackgroundWe aimed to investigate the range of intakes linked to efficacy and to make an initial assessment of variability in response to the water-soluble tomato extract, Fruitflow®. Platelet response to ADP agonist and thrombin generation capacity were monitored at baseline and 24h after consuming 0,30,75,150,300mg of Fruitflow® in a randomized, double-blinded crossover study in male subjects 30–65 years of age (n=12, ISRCTN53447583,24/02/2021). ResultsResults showed that the changes from baseline aggregation (-12.0±13.9 to -17.7±15.7%) and thrombin generation (-8.6±4.1 to -11.3±2.3%) achieved for the 75mg, 150mg, and 300mg supplements were equivalent. Effects observed for 0 mg and 30mg supplements were non-equivalent to150mg and not different from baseline (aggregation changed by -0.7±10.2 to 3.0±5.0%, thrombin generation by 0.8±3.1%). ConclusionsThe data suggest that the efficacious range for Fruitflow® lies between 75mg and 300mg, depending on the individual. It may be pertinent to personalize the daily intake of Fruitflow® depending on individual platelet response.

Document acquired independently by the two collectors according to inclusion and exclusion criteria. System analysis was performed by Revman 5.3 software.Results: A total of seven case-control studies were included in the study, including 3045 patients and 3545 controls. The results of the systematic analysis showed that all studies on upper gastrointestinal tumors were combined: random effects model, dominant genetic model GG + GA vs AA: the difference was not statistically significant [OR=1.15; 95%CI: 0.74-1.81]; recessive genetic model GG vs GA + AA [OR=0.99; 95%CI: 0.74-1.31], codominant model GG vs AA [OR=1.14; 95%CI: 0.67-1.95], GA vs AA [OR=1.20; 95%CI: 0.80-1.79], allele model G vs A [OR=1.06; 95%CI: 0.82-1.38]. The above results show CTLA-4 + 49A > G locus. There was no correlation between gene polymorphism and susceptibility to upper gastrointestinal tumors including gastric cancer and esophageal cancer. After the five studies on gastric cancer were combined, each genetic model showed that the CTLA-4 + 49.Conclusion: This study showed that there was no correlation between single nucleotide polymorphisms in CTLA-4 + 49A > G locus and upper gastrointestinal tumors including gastric cancer and esophageal cancer.
Studying the Impact of Indian Urban Parenting on Emotion Regulation in female children and adolescents during COVID-19: A Cultural Analysis

We focus on Indian parenting and its impact on emotion regulation in female first born offspring residing in an Urban complex. The case report relies on a case report analysis between two groups, A and B. Group A comprises two families, and their young children, while Group B consisted of two families with adolescents. Extensive qualitative analysis has been conducted to understand the ground reality of Indian parenting practices and the emotional mechanisms present in children and adolescents during the COVID-19 crisis. Multiple baseline design was followed and the measures employed were the Parenting style questionnaire (Robinson Et. Al., 1995) and Difficulties in emotion regulation scale (Gratz & Roemer, 2004), where the parents, ages between 30 and 55 years, were supposed to fill the PSQ and their children (Ages between 4 and 18 years) completed the DERS through an online test form. This was followed by a semi-structured interview to complete the analysis and get a better idea about the family dynamic. We achieved two goals; (1) It was found that the Indian family functions in a complicated manner and studying it required creating novel constructs to accommodate the cultural diversity. Conveying a real lack of present work done by Indian researchers to effectively come to any conclusion, (2) It was discovered that young children are bound to face novel challenges, caused by a new style of parenting which comprises of mixed parenting style with a focus towards maintaining cultural values and social norms. Adolescent females, unfortunately do face an authoritarian father, on an above average basis, but this is changing as the parents from Group A were observed employing mixed parenting. Which has proved our assumptions correct.
Blockchain-based Learning for Health Screening with Digital Anthropometry from Body Images

Anthropoid images encode reliable biometric information in abundance. Recent research on image-based screening drives this effort to investigate the feasibility of interpreting the inherent nutritional state from multidimensional human body images. However, anthropometric databases are becoming increasingly essential and grow in parallel to achieve efficient system designs. This paper presents a novel imaging-based strategy in an augmented environment to quantify the human anthropometric features with blockchain-based learning to generate a diagnosis report. It includes evaluating the attributes such as height, weight, forearm, wrist, waist, Mid-Upper Arm Circumference (MUAC), Knee, Feet, head length from an image using the Augmented Reality and Blockchain-based Transfer Learning for diagnostic accuracy. We developed a novel skeleton known as FETTLE to determine the role of body measures for assessing nutritional conditions and body weight from human body images. It forms an instantly applicable technique aimed at evaluating children’s growth patterns all through their initial ages. FETTLE app can also be operated on bedridden people as a screening mechanism to spot their risk of pressure ulcers and undernutrition, followed by a more structured examination. Our approach is superior in accuracy measures with consortium blockchain-based learning context with privacy-preserved medical data sharing and high-end user experience and interaction. Our framework is proved to gain about 97.26% validation accuracy on anthropoid images.

Background: Recently, some lncRNAs in studies were also regarded as the potential prognostic biomarkers for renal cell carcinoma. The aim of this meta-analysis is to evaluate the prognostic significance of lncRNAs for RCC and explore their correlation with lymph node metastasis (LNM) and distant metastasis (DM).Methods: A series of electronic databases were chosen to retrieve the eligible articles. A total of 35 studies involving 3535 patients with RCC were included finally. The statistical analysis was performed using STATA 16.0 and review manager 5.3 software. The relative risk (RR) and hazard ratio (HR) with 95% confidence interval (CI) were calculated to assess the significance. The stratified subgroup analysis was conducted by the up-regulated group and down-regulated group. Additionally, the sensitivity analysis was performed by the sequential omission of individual studies, and the publication bias was detected using Begg’s test.Results: The results indicated lncRNAs expression levels were correlated with LNM for up-regulated lncRNAs (RR=2.06, 95% CI: 1.53-2.78, p<0.00001) and down-regulated lncRNAs (RR=0.49, 95% CI: 0.31-0.76, p=0.002). The expression levels of lncRNAs were closely related to DM (RR=1.67, 95% CI: 1.21-2.29, p=0.002). Moreover, the expression levels of these lncRNAs were also associated with the overall survival (HR=1.71, 95% CI: 1.28-2.28, P=0.0003).Conclusions: This meta-analysis suggested that lncRNAs could be regarded as biomarkers for clinical lymph node metastasis or distant metastasis and also may serve as the potential predictive factors of prognosis for RCC.
