A Communication of Persuasion in the Management of Character Emotions through Hikayat Nakhoda Muda
Authors: Abdul Rahman Nadiatul Shakinah
Published: June 2022

Emotions play an essential role in human life because emotions affect a large part of life. Emotions are God's gift to humans that will give a variety of reactions, response, and behaviours. Emotions will guide and colour the path of human life. The construction of positive and negative emotions depend on the acceptance and interpretation of the individual towards an event experienced. Positive emotions will lead to positive life and thoughts. On the other hand, negative emotions will lead to an unmanageable life with no emotional control and rowdy behaviour. If a human being is emotionally negative, the individual will have emotional disorder. Emotional disorder needs to be controlled and dealt with promptly without being protracted and prolonged. Communication is one of the steps in dealing with emotional problems. In this case, this study will analyse the persuasive communication strategy in managing character emotions through the Hikayat Nakhoda Muda used as study data. The research also use the Social Judgement Theory to strengthen the arguments of discussion. The results found that the persuasive communication strategy is divided into two: persuasive verbal communication and persuasive non-verbal communication. Therefore, this study proves that the implementation of persuasive communication successfully controls and manages disturbed and unstable emotions.
Structural Identifiability of Feedback Systems with Nonlinear Adulterating
Authors: Karabutov Nikolay
Published: June 2022

We consider the structural identifiability estimation problem of Nonlinear Feedback Systems (NFS) with nonlinear adulterating. The problem of NFS Structural Identifiability (NFSI) has not been studied. Studying the NFSI problem guarantees the possibility of nonlinearity identification under uncertainty. Two cases of the adulterate influence are analyzed: (i) additive effect of feedback nonlinearity on the nonlinearity in the straight chain (ii) nonlinearity argument nonlinear adulterating in straight chain of the system. The basis for the identifiability estimation is: (a) the Geometric Frameworks (GF) analysis method reflecting properties of the nonlinear system; (b) structural frequency diagrams, and (c) the hierarchical immersion method. We obtain conditions of identifiability, unidentifiability and local identifiability for NFS. The influence of the nonlinear argument is analyzed on the system identifiability. We propose conditions for system unidentifiability verifying with a nonlinear argument of the function. The influence of the nonlinear argument is analyzed for estimating the system identifiability. Results are applicable in the synthesis of nonlinear control systems.
Place Branding for and Through Gastronomy
Authors: Gulisova Barbora
Published: June 2022

As a representation of a place's culture and identity, gastronomy is often a building stone of a place brand. Therefore, food, culinary experiences, and gastronomy are often used in tourism by DMOs, governments, and industry groups for place branding. This article aims to review studies
investigating the relationship between gastronomy, tourism, and place branding, identify patterns in the research, and propose further research avenues. Thematic analysis is applied, and five patterns, or themes, are identified from the review: (1) host versus guest perspective; (2) types
of gastronomy—that is, authentic, exclusive, market-driven, single cuisine versus multicultural or cosmopolitan; (3) actors and collaborations—that is, clusters, entrepreneurship, restaurants, labeling, UNESCO designations, roles of different actors, and broad stakeholder support;
(4) type of place—that is, nation, city, region, small town, islands; and (5) direction of relationship—that is, whether gastronomy is used for place branding, or whether place brand influences the perception of gastronomy. Finally, further research avenues are proposed for each
of the themes.
Challenges and Strategies to Minimize Campaign Violations of Regional Head Election
Authors: Wiredarme Wiredarme , Muttaqin M. Zaenul
Published: June 2022

This study aims to analyze the regulation on challenges and strategies to minimize campaign violations of the Regional Head Election simultaneously in 2020 during the Covid-19 pandemic. The research method used is normative juridical. Data was collected using literature study techniques on primary, secondary, and tertiary legal materials. The collected legal materials were then analyzed using qualitative data analysis methods. The results show that Law No. 6 of 2020, Regulation of General Election Commission No. 5 of 2020, Regulation of General Election Commission No. 13 of 2020, and Regulation of Election Supervisory Board No. 4 of 2020 has not been able to address the various violations of the 2020 Regional Head Elections campaign during the Covid-19 pandemic. In this case, mass mobilization exceeds the amount determined based on Regulation of General Election Commission No. 13 of 2020. In addition, the massive role of political buzzers indicates that money politics is rarely absent during the Regional Head Election campaign. Therefore, it is recommended to establish special regulations for pandemic situations, including prohibiting donations or other money politics. Furthermore, the involvement of political buzzers in online media who often use anonymous accounts requires specific regulations, including account legalization, content configuration, and content narrative. In addition, the application of health protocols in the Regional Head Election campaign should be based on Law No. 6 of 2018, which contains strict sanctions for violators of health protocols. From these recommendations, it is hoped that it will minimize the campaign violations of the Regional Head Election simultaneously in the future.
Liquid biopsy in biliary tract cancer from blood and bile samples: current knowledge and future perspectives
Authors: Arrichiello Gianluca , Nacca Valeria , Paragliola Fernando , Giunta Emilio Francesco
Published: June 2022

Biliary tract cancer (BTC) is an aggressive tumor characterized by a poor prognosis. In the latest years, targetable genetic alterations have been discovered in BTC patients, leading to the approval of new targeted therapies. Liquid biopsy, which is a non-invasive method for detecting tumor biomarkers from fluid samples, is a useful tool for diagnosis and molecular characterization, but also for prognosis assessment and monitoring of treatment response. In this review, recent works on liquid biopsy in BTC patients were analyzed, focusing on some relevant aspects for clinical use and trying to depict the future role of this technique. Moreover, differences between plasma and bile samples were pointed out, in light of the peculiar biology of BTC and the possibility of using bile as an alternative source of cell-free DNA (cfDNA) for genomic analysis. In the era of precision oncology, the increasing adoption of liquid biopsy in BTC patients will certainly improve the management of this disease.
Portrét Alexandra III. Velikého (336–323 př. Kr.) na mincích
Authors: Mašek Michal
Published: June 2022

Pictures on the obverse side of the silver coins of Alexander the Great are commonly regarded to be portraits of the King himself. However, since the same portrait was also used by his predecessors, this theory cannot be accepted. It can only be assumed that the head of Heracles gradually became to be considered a portrait of Alexander III and continued to be used not only by die engravers but also other artists, such as that one making the so-called Alexander Sarcophagus. The real portrait can be found only on the Egyptian bronze coin of Price no. 3960 type.
Addenda k typom keltských mincí z oppida Hradiště u Stradonic
Authors: Fröhlich Július
Published: June 2022

The documented three coins, until now unrecorded among the finds from the Hradiště near Stradonice, extend the range of Celtic coin types that were imported to this oppidum from the west. The first one, an unusual stater of the Kellner I B type, is important in the Czech area since most of the coins from the Regenbogen-Schusselchen group found at the Stradonice oppidum are subaerates. The second specimen, a quarter-quinar, probably belonging to the quinars of the so-called Prague type, is an extremely rare coin which can be classified as belonging to this group based on the image of a stylized horse on the reverse. These coins were probably brought to the Stradonice oppidum from the Thuringian area in present-day Germany. The third and last small silver coin of the ‘mit strengem Gesicht’ type represents a rather unique issue imported to the Czech territory from the area of southern Germany and, together with the above-mentioned coins, it attests to the trade contacts maintained by the population of the Hradiště oppidum with merchants from the territories of today’s Germany from the middle of the 2nd to the middle of the 1st centuries B.C.
Denár Karla II. Holého nalezený v Chotěšově
Authors: Čechura Martin , Břicháček Pavel
Published: June 2022

An early medieval silver denier of the West Frankish King and Emperor Charles II the Bald (843–877) was found during a metal detector survey of a wellknown polycultural site with remnants of settlements from the Neolithic to the High Middle Ages Periods. Despite small traces of corrosion, the coin is perfectly preserved and was probably never in circulation. The denier is the eighth known find of a Carolingian coin in Bohemia, and the first specimen found in the Pilsen Region. The importance of the site is given mainly by its location on the Regensburg route, which provided the main connection between Bohemia and Bavaria. The importance of this route is underlined by the location of the customhouse with the church of St. Jakub in Domažlice, and especially the Benedictine mission cell in Cham, similar to the findings of Carolingian coins in Bavaria.

Authors: Militký Jiří
Published: June 2022

In 2000, a rescue archaeological survey was conducted on the premises of today’s nursing home on the Dómský Hill, the place of early medieval hillfort. During the excavations, three rare early medieval coins were found. These are deniers of the Dukes Jaromír (Cach 1970, no. 256), Vladislav II (Cach 1972, no. 597) and Bedřich (Cach 1972, no. 635). Another, till now unpublished denier of Vratislav II (Cach 1972, no. 352) was found in a grave. These coins illustrate the intensive money circulation at the site (including its hinterland) from which a total of 11 earlier coin finds are known and reflect the importance of the Litoměřice settlement during 10th and 12th centuries.
Polskie znaleziska brandenburskich denarów askańskich podrabianych w epoce (ok. 1295–1300)
Authors: Szczurek Tadeusz
Published: June 2022

During archaeological excavations in Ostrow Lednicki in Greater Poland, and Lubrza in Silesia, two deniers were discovered which, according to their designs, refer to the Brandenburg deniers of the Ascanian Period. However, they differ from the original Margravial issues in a more primitive execution, and despite being similar they also vary in their appearance from each other, especially as for the reverse images. The particular way of coin production which does not fall into the category of imitations, nor, due to the precious metal used, is in fact a forgery, is euphemistically called „counterfeit” for the purposes of this study. The type from Lubrza (Da. 135) is quite rare and occurs mostly as a single specimen in the hoards found west of the Oder River. On the other hand, the denier type from Ostrow Lednicki (Da. 136) is so far the only find and the second known specimen. These coins could have been struck in the countries bordering with Brandenburg (Saxony-Wittenberg, Anhalt) between 1295 and 1300.

NEW HORIZONS PROCESSING OF TECHNOGENIC WASTE OF THE COPPER INDUSTRY
Authors:   Navoi State Mining Institute, Navoi, Republic Of Uzbekistan, Vokhidov B.R.
Published: June 2022

At the present time, in the mining and metallurgical industry, there are trends in the processing of man-made waste that have accumulated over the course of many years. Since the world's reserves of ore deposits with a high initial content of non-ferrous metals and easily processed ores are currently practically depleted. This is due to a decrease in the volume of processing of conditioned ores and the involvement in the development of industrial waste, refractory ores and off-balance from low-grade dumps. High prices for metals on the world market create a favorable environment for the development of technologies for the extraction of precious metals involving the processing of mineral resources of technogenic origin. The work studies the mineralogical composition of industrial waste from the copper industry in the conditions of JSC "Almalyk MMC", determined the effectiveness of methods for the selective extraction of platinoids and paid attention to the methods of dissolution, reduction of platinum metals and methods of their purification from various impurities. Based on the study of this topic and the analysis of the results of the research, the authors proposed an optimal technology and complex methods for extracting platinum, palladium and rhodium from industrial waste using selective methods suitable for each metal separately using hydrometallurgy and pyrometallurgy. Hydrometallurgical methods have been developed for the purification of palladium, platinum and rhodium with treatment, respectively, with formic, citric and nitric acids. As a result of the developed technologies, the possibility of complex extraction of platinum group metals from industrial waste has been achieved. In this case, the end-to-end extraction of all platinoids is over 80%.

Purpose of the study. To analyze the physical and neuropsychiatric development of pediatric patients who underwent cranial irradiation in the period from 2015 to 2020 in the radiotherapy department of the National Research Center of Oncology and to assess the risk of post-radiation complications.

Materials and methods. 17 children aged from 3 to 17 years were hospitalized under medical supervision in the department of pediatric oncology of the National Medical Research Centre for Oncology. All the children underwent a course of conformal radiation therapy totally on the brain area and the first two cervical vertebrae in the radiotherapy department of the National Medical Research Centre for Oncology. 13 patients (76.7 %) underwent radiation therapy due to the prevention of neuroleukemia with a total dose of 12 Gy (a dose per fraction was 2 Gy), 2 patients with a confirmed relapse of acute lymphoblastic leukaemia (ALL) (11.65 %), 1 patient with a confirmed diagnosis of neuroleukemia (5.8 %) and 1 patient from the high-risk group (5.8 %) – with a total dose of 18 Gy (a dose per fraction was 2 Gy). Further 75 month regular medical checkup was carried out on the basis of the Regional Children's Clinical Hospital for.

Results. None of the surviving patients showed growth retardation. Two patients (11.65 %) complained of increased fatigue, decreased concentration; one patient (5.8 %) showed unmotivated irritability and aggression during the examination. Intellectual development corresponded to age in all patients (100 %). One patient (5.8 %) experienced episodes of nausea and vomiting (grade 1 on the CTCAE scale), three patients (17.7 %) suffered from headache (grade 2 on the CTCAE scale), three patients (17.7 %) complained of fever up to 38 °C (1 degree on the CTCAE scale). Two out of 17 ALL patients died due to disease progression.

Conclusion. Taking into account the different time intervals between treatment and the moment of the study (from 9 to 75 months), cranial irradiation demonstrates relative safety for patients undergoing treatment during critical periods of development of both physical and neuropsychic spheres. However, an objective assessment of the development prospects is difficult due to the relatively short time after undergoing therapy (from 9 to 75 months) and a small sample of patients.

Lung cancer (LC) takes the first place in the structure of overall oncology in males. More than 1.8 million of new cases of lung cancer (LC) are registered each year worldwide. LC is the leading cause of cancer death in both developing and developed countries, and the 5 years survival rate is as low as 19 %. Many factors explain such unsatisfactory outcomes, including the LC diagnosis at an advanced stage, when the currently available treatments can rarely provide cure. Non-small cell lung cancer (NSCLC) with chromosomal rearrangement of anaplastic lymphoma kinase (ALK) is sensitive to targeted therapy with tyrosine kinase inhibitors (TKIs). Tumor cells containing ALK fusion are sensitive to TKIs – targeted drugs that have significantly improved the results of treatment of patients with ALK-positive NSCLC, half of whom survive more than 6.8 years after diagnosis. The number of patients with ALK-positive NSCLC varies, so ALK rearrangements are detected in about 3–7 % of lung adenocarcinomas, which accounts for up to 60.000 new cases of the disease annually worldwide. ALK-positive NSCLC is observed almost exclusively in adenocarcinomas associated with persons of younger age, male and never smoked or smoked a little. Patients with ALK-positive stage I–III NSCLC are shown treatment similar to patients with wild-type NSCLC, including surgery, radiation therapy, chemotherapy or multimodal treatment, depending on the stage of the tumor process. Numerous ALK TKIs have been developed in recent years, including alectinib, which is the current preferred first-line agent for patients who haven’t received therapy. The study of the mechanisms of resistance has led to the development of next-generation ALK inhibitors that better penetrate the central nervous system, actively affecting brain metastases. This review highlights the current state and prospects for the development of ALK-positive NSCLC therapy.
Genes copy number variation in colorectal cancer patients as a marker of the disease clinical outcome and response to therapy

Published: June 2022

Abnormal gene copies, a special type of genetic polymorphism, is a hallmark of most solid tumors, including colorectal cancer. Abnormal copy number of genes leads to tumor-specific genomic imbalance, which manifests itself already in precancerous precursor lesions. The aim of this review was to systematize the scattered data on changes in gene copy number observed in colorectal cancer and their impact on the outcome of the disease and response to therapy. The data from 58 studies was analyzed on gene copy number changes and their expression in primary carcinomas, cell lines and experimental models. This review examines the spectrum of genetic changes that lead to colorectal cancer, describes the most frequent changes in the number of gene copies at different stages of the disease, and changes in the number of gene copies that can potentially affect the outcome of the disease of individual patients or their response to therapy. In fact, aberrant gene copy number as a form of chromosomal imbalance affects a number of genes that provide a metabolic selective advantage for a tumor cell. Changes in the genes copy number in colorectal cancer patients not only positively correlate with changes in their expression, but also affect the levels of gene transcription at the genome-wide scale. Aberrant gene copy numbers are closely related to disease outcome and response to treatment with 5 fluorouracil, irinotecan, cetuximab and bevacizumab. Nevertheless, the possibility of translating the genes copy number index into clinical practice requires further research.

Authors: Driver Matthew K. , Harper Irma
Published: June 2022

The study of effective school leaders and teacher evaluators has been a topic of interest to researchers for decades. While there have been a number of studies performed on urban schools, this study seeks to add to the body of research from the perspective of rural schools. The purpose of this qualitative study was to explore the strategies and practices teacher evaluators employ in the evaluation process to improve instructional practices on their campuses. The study highlights the important role that relationships, communication, organization, training, targeted feedback, and calibration play in creating an environment. While each principal noted the factors above are important to the evaluation process, they differed in their beliefs and approaches to improving teacher performance. Findings suggest that principals must use a variety of tools and methods to engage teachers in the evaluation process, which in turn, will help improve their instructional practices.

Through this partnership, the Networked Improvement Community focused on root causes of recruitment and retention challenges in the rural school districts. Using an improvement science approach, a 14-month residency model was developed to recruit qualified community members to transition to the teaching profession, with a focus on mirroring the diversity of the local community. This study focuses on the development of the residency model and the recruitment of teacher residents for the initial cohort of this alternative teacher preparation program.
Estimating Coconut Production and Productivity of Local Tall in Taliabu Island Using Drone and Sampling Population
Authors: Novarianto Hengky
Published: June 2022

The objective of this research is to know the local tall coconut population, production and productivity in Taliabu Island, North Maluku Province, which is crucial for the industry. The aerial photography method using drones has been carried out to determine the distribution of coconut diversity, palm age, production potential and local coconut productivity. Production data and coconut fruit components were carried out on 6 sample populations. The result (Arvitech) revealed that in Jorjoga, the area under coconut was 335 ha out of the surveyed area of 1,066 ha. The total number of coconut palms was 55.728 palms. The Geomac survey carried out in Tabona indicated there were 77,629 coconut palms in an area of 1,000 ha. The fruit component analysis showed the weight of the whole fruit and the fruit without husk at the Jorjoga was 1,340-1,629g/fruit, and 805-1,033g/seed nut, and in Tabona was 1,478-1,577g/fruit and 944-966g/seed nut. The coconut production potential at Jorjoga was 9,539 nuts/ha/year, higher than that of Tabona with 7,227 nuts/ha/year. The coconut production and productivity estimation information can be used to develop a coconut replanting and rehabilitation strategy wherein selected varieties with good attributes for the tall coconut can be planted and ensure their proper maintenance, thus can be used to estimate the need for raw materials required for the establishment of the coconut industry in Taliabu Island. Determining the coconut population status can increase the production and productivity of coconut palms through rejuvenation, rehabilitation and expansion of coconut plantations using superior tall coconut seedlings.

Anterior acute uveitis is the most frequent extraarticular involvement in patients with rheumatologic diseases such as spondyloarthritis and it can often be the first clinical feature. In many cases, a prompt recognition and an early referral by the ophthalmologist to the rheumatologist can be crucial for the accurate diagnosis of these disorders. On the other hand, recognition of the signs and symptoms of ocular inflammation by the rheumatologist can facilitate prompt referral to an ophthalmologist and improve patient outcomes. Comprehensive care through collaboration between ophthalmologists and rheumatologists can help with optimal diagnostic and therapeutic decisions tailored to the individual patient.

Published: June 2022

With the acceleration of Urban Renewal Program, particularly in large cities of Turkey, the problem of finding land-fills and eliminating construction waste with the least environmental pollution necessitates its value-added recycling. However, the presence of adhered weak mortar layer, comprising 20-70% of recycled concrete aggregate (RCA), limits the use of RCA or lowers its inclusion level in concrete mixtures. Within the scope of this study, limestone- and basalt-bearing RCA obtained from 6 different concrete mixtures with three different water/cement ratios (0.45, 0.60, 0.70) were prepared and their water absorption, specific gravity, dense and loose unit weight, flatness indices, Los Angeles degradation values were determined. The results showed that, increasing w/c ratio of the parent concrete increased water absorption of the resultant RCA. However, the specific gravity, unit weight, abrasion resistance and flakiness index of RCA were decreased by increasing w/c ratio of the parent concrete.

The purpose of this research is to investigate the effect of ethical leadership on creativity and estimates the mediating effect of organizational support for creativity in this relationship. A cross-sectional approach with a sample of 258 professionals, employees of different companies and economic sectors in the city of Lima, Peru, was employed. Valid and reliable instruments were used to assess the perception of the variables studied, and direct and indirect effects were tested using structural equation models. The results indicate that ethical leadership positively influences creativity both directly and through organizational support for creativity. This draws attention to the opportunity that leaders have to optimize organizational processes, procedures, and protocols oriented toward responsibility and respect for others to encourage creative behavior in employees. Furthermore, theoretical, and practical implications are discussed.
An Analytical Fourier Transformation Model for the Production of Hard and Soft X-Ray Time Lags in Active Galactic Nuclei: Application to 1H 0707-495

The variability of the X-ray emission from active galactic nuclei is often characterized using time lags observed between soft and hard energy bands in the detector. The time lags are usually computed using the complex cross-spectrum, which is based on the Fourier transforms of the hard and soft time series data. It has been noted that some active galactic nuclei display soft X-ray time lags, in addition to the more ubiquitous hard lags. Hard time lags are thought to be produced via propagating fluctuations, spatial reverberation, or via the thermal Comptonization of soft seed photons injected into a hot electron cloud. The physical origin of the soft lags has been a subject of debate over the last decade. Currently, the reverberation interpretation is recognized as a leading theory. In this paper, we explore the alternative possibility that the soft X-ray time lags result partially from the thermal and bulk Comptonization of monochromatic seed photons which, in the case of the narrow-line Seyfert 1 galaxy 1H 0707-495, may correlate with fluorescence of iron L-line emission. In our model, the seed photons are injected into a hot, quasi-spherical corona in the inner region of the accretion flow. We develop an exact, time-dependent analytical model for the thermal and bulk Comptonization of the seed photons based on a Fourier-transformed radiation transport equation, and we demonstrate that the model successfully reproduces both the hard and soft time lags observed from 1H 0707-495.

We explore the evolution of the X-ray luminosity function of quasars and the intrinsic correlation between the X-ray and 2500 Å ultraviolet luminosities, utilizing techniques verified in previous works and a sample of over 4000 quasars detected with Chandra and XMM-Newton in the range 0 < z < 5. We find that quasars have undergone significantly less evolution with redshift in their total X-ray luminosity than in other wave bands. We then determine that the best-fit intrinsic power-law correlation between the X-ray and ultraviolet luminosities, of the form

Inferring the Gas-to-Dust Ratio in the Main Planet-forming Region of Disks
Authors: Jermyn Adam S. , Kama Mihkel
Published: June 2022

Measuring the amount of gas and dust in protoplanetary disks is a key challenge in planet formation studies. Here we provide a new set of dust depletion factors and relative mass surface densities of gas and dust for the innermost regions of a sample of protoplanetary disks. We do this by combining stellar theory with observed refractory element abundances in both disk hosts and open cluster stars. Our results are independent of, and complementary to, those obtained from spatially resolved disk observations.

Published: June 2022

BACKGROUND: Osteoarthritis is a disease that causes inflammation, injury, and loss of structure and function of cartilages. A nonpharmacological treatment that is considered to be effective and safe and has minimal side effects is red ginger.

AIM: This study investigates the chemical constituents of red ginger extract and the effectiveness of red ginger gel in reducing knee joint pain in the elderly with osteoarthritis.

METHODS: This research is a quasi-experimental study with pre- and post-test design. Samples were selected using a purposive sampling technique. The intensity of knee joint pain pre- and postadministration of 0% (control group) and 10% (intervention group) red ginger gel and the chemical components of red ginger extract were collected. Gas chromatography–mass spectrometry analysis showed four different components of essential oils that have anti-inflammatory and analgesic effects in the red ginger extract.

RESULTS: Results showed no difference in the pre- and post-test result in the control group (p = 0.16 > 0.05). Significant differences were found in the pre- and post-test results of the intervention group (p = 0.001 < 0.05). There was a significant difference in the decrease of knee joint pain after intervention between the two groups (p = 0.001 < 0.05).

CONCLUSION: It can be concluded that 10% red ginger gel is effective in reducing knee joint pain in the elderly with osteoarthritis.

BACKGROUND: Inflammatory bowel disease (IBD), such as Crohn’s disease (CD) and ulcerative colitis (UC), is characterized by intestinal inflammation and epithelial damage. Impaired mucosal cell barrier function mainly associated with thinning of the mucin layer may be the initial events underlying injury and inflammation in UC. Impaired expression of specific mucins is closely associated with IBD. MUC2 is a gene that produces mucin, which is predominant in the colon in humans and rats.

METHODS: This study is an experimental study with a posttest-only design. The sample comprised 16 colitis-induced rats. Induction of colitis was done by giving a solution of dextran sodium sulfate (DSS) 2.5% 1 mL/day orally for 7 days. MUC2 gene expression was measured by rtPCR. The clinical severity of colitis was classified based on the disease activity index (DAI) score. The degree of histopathological damage was classified based on the score of colonic histology observations. The statistical analysis was done by the Shapiro–Wilk normality test and continued with an independent samples t-test.

RESULTS: There were differences in MUC2 gene expression in mild and moderate colitis (1.81 vs. 2.99) but the difference was not significant (p > 0.05). MUC2 gene expression also differed in mild and severe histopathological damage degrees (2.32 vs. 2.1) but the difference was not significant (p > 0.05).

CONCLUSION: It was concluded in this study that MUC2 gene expression did not have significant differences based on the clinical severity of colitis and the degree of histopathological damage to the colonic mucosa in colitis-induced rats.

Published: June 2022

Backgrounds. Microscopic decompression (MD) has been widely used as an alternative to open decompression. Lately, biportal endoscopic spinal surgery (BESS) - a new approach in minimal-invasive spinal surgery – has also been used with good results.  Although both groups can achieve adequate lumbar decompression, there is still a lack of evidence regarding their comparison. We aim to compare the outcomes of both techniques in a one-year follow-up.
Methods. This is a retrospective study in 100 consecutive patients with symptomatic lumbar spine compression due to herniated nucleus pulposus (HNP) and lumbar canal stenosis (LCS) that was treated by either BESS or MD. Clinical evaluations using Visual Analog Score (VAS), Oswestry Disability Index (ODI), and SF-36 questionnaire were obtained. Objective data such as surgery duration, amount of postoperative drain production, and hospital length of stay were collected. Complications were noted throughout the follow-up time.
Results. The BESS group had a significantly lesser surgical duration, drain production, and length of stay. At one year follow-up, both groups achieved significant improvement in VAS, ODI, and SF-36 compared to the preoperative condition. Complications were not observed in the BESS group.
Conclusions. Both procedures were comparably effective to treat lumbar stenosis. Although this study shows superiority with BESS technique in immediate and long-term follow-up, the final choice may depend on the surgeon's preference

School myopia is a term that is used for the development of myopia at school age. The Child Heart and Health Study in England (CHASE) 2010, the prevalence of myopia in Southeast 25,2% at school age. The risk factor for school myopia more complex and one of the environmental factors were near activity. Accommodation, convergence, and miotic pupil are third signs when we look closely. Convergence and accommodation were measured with Near Point of Convergence (NPC) and Amplitude Accommodation (AA). This research aims to know the correlation between NPC and AA with school myopia progression. Research location at Sibang Gede 1st elementary school, Kuta 1st elementary school, Jimbaran 4th elementary school, and Kerobokan Kelod 2nd elementary school. The sample was obtained by Convenience sampling, Stratified Sampling, and Consecutive sampling techniques. Data were analyzed and searching for correlation Near Point of Convergence (NPC), Amplitude Accommodation (AA), and myopia progression was done by bivariate and multivariate analysis with age, gender, and myopic parent. This Research has 125 sample who mostly female 56 %, age at 7 yo 24.8%, median near activity 78 Dh/ week, myopic parent 27.2%. Correlation NPC showed inversely to progression of myopia (NPC Break r = -0.332, p<0.001; NPC Recovery r = -0.335, p<0.001). Correlation AA and progression of myopia showed positive correlation (AA Binocular r = 0.287, p=0.001; AA RE r = 0.226, p=0.017; AA LE r = 0.261, p=0.07). Age has correlation with progression of myopia with (p<0.05). There is a correlation between NPC and AA with school myopia progression at near activity in Badung Regency. Smaller NPC was correlated with progression of myopia and higher AA was correlated with progression of myopia although age was correlated with myopia progression.
