Two Cases of BRASH Syndrome
Authors:   USFR Internal Medicine, CHUJRB of Antananarivo, Madagascar, Nainanirina Sylvain
Published: August 2022

BRASH syndrome is a rare entity that is often underdiagnosed. Recently known in 2016, it falls within the scope of drug toxicity. BRASH syndrome consists of bradycardia, renal failure, shock, and hyperkalemia, secondary to atrioventricular node blocking drugs. We report two cases of BRASH syndrome in order to encourage the physician to think about it in front of bradycardia associated with hyperkalemia in chronic renal patients and to intensify the monitoring of renal insufficiency under atrio-ventricular node blocker. The first case was a 59-year-old man, hypertensive-diabetic, suffering from a stage IV chronic renal disease not dialyzed, having taken as antihypertensive drugs: Carvedilol 12.5 mg and Amlodipine 10 mg, presenting a picture of BRASH syndrome triggered by the intake of diuretic. The second case was a 64-year-old hypertensive-diabetic man, presenting a mixed vascular and diabetic nephropathy stage V not dialyzed, under Carvedilol 12,5 mg and Amlodipine 10 mg making a picture of shock and severe bradycardia with aggravation of a hyperkalemia labeled as BRASH syndrome on bacterial pneumonia.

This research is focused on testing how the austenite breakthrough occurs in ferrite at a temperature of 850ºC. For this purpose, an experiment has been designed to deal with this fact at this temperature. A piece of F-114 steel was placed in contact with a piece of ARMCO iron. The F-114 steel at 850ºC transforms into austenite while the ARMCO iron remains as ferrite. The breakthrough takes place by slow diffusion of the carbon from the F-114 steel into the ferritic ARMCO iron matrix. This feed increases the carbon content of the ARMCO iron until it transforms it into austenite. The intimate contact between ARMCO iron and austenite has been carried out by hot forging without exceeding 850ºC. The metallographic study was carried out by scanning electron microscopy.

Measurement of Swash Infiltration Rates on Sandy Beaches
Authors: Brathwaite Shani , Villarroel-Lamb Deborah
Published: August 2022

The swash zone is a critical area of the nearshore hydrodynamics contributing significantly to beach evolution. The role of infiltration of water during swash events has been investigated, but an enhanced data collection methodology will improve prediction and analyses of swash processes. A new and simple technique was proposed to determine the rate of swash infiltration on sandy beaches. Direct, in situ measurements of swash infiltration rates were conducted on the sandy beach of Las Cuevas Bay located on the north coast of Trinidad. The method incorporated the use of a double ring infiltrometer paired with a Bluetooth water level logger, where infiltration rates were inferred from the changes in water level recorded within the double ring infiltrometer. Observed infiltration rates were variable and showed a dependency on sediment characteristics and location of measurement. The study also sought to ascertain any correlation between the measured infiltration rates and sediment properties. While correlation was generally low, the use of the maximum recorded infiltration rate yielded the best correlation across most cases observed. In addition, the highest correlation occurred with the D10 grain size for the upper beach, and the D90 grain size for the lower beach which is closer to the Still Water Line. The sediment sorting ratio of D84/D16 and D90/D10 showed the best correlation for the upper and lower beach locations respectively. While the field method was practical, the results of the study demonstrate a need to capture additional bed features that contribute to the rate of infiltration.

Erwinia amylovora bacteriophages can be considered as potential agents for the control of fire blight. In present work bacteriophages Hena2, Roscha1, Dichka, Pixel, and VyarbaS, isolated in Belarus, are characterized. The ability of bacteriophages to multiply and inhibit the bacterial growth was studied. According to the OD600nm measurement data, infection with bacteriophages reduced the E. amylovora growth by 59 ± 9.7–90 ± 7.4 %, as well as the CFU/ml, on average, 40 ± 6.7– 163 ± 86.7 times. When the bacterial cultures of E. amylovora 1/79Sm was infected with bacteriophages, the frequency of the phage-resistant mutants incidence ranged from 3.2 × 10–3 ± 2.2 × 10–3 to 5.1 × 10–3 ± 4.3 × 10–3 %. Relatively high values of the lysis index of the E. amylovora bacterial culture were demonstrated for the studied bacteriophages. However, the presence of viable cells in phage lysates and the high frequency of the phage-resistant mutants incidence indicate the need to apply cocktails of bacteriophages for elimination of bacteria.

Authors: Maaruf Nurul Atiqah , Jusoh Norhana
Published: August 2022

The bone scaffold has become a promising alternative in bone tissue engineering due to the limitation associated with current bone treatments. However, the selection of scaffold material that could accurately mimic the extracellular matrix of native tissue remains challenging. Owing to its biological origin properties, natural materials including fibrin are widely used as scaffold materials as compared to synthetic materials. Fibrin has been recognized as one of the appealing natural biopolymers, which possesses unique characteristic due to its natural formed nano-scaffold, which provide a temporary matrix that facilitates cellular activities of cells. Fibrin has shown remarkable effects over other biomaterials in inducing angiogenesis and osteogenesis in bone regeneration owing to its mechanical and biological properties. In this article, we highlight the significance of fibrin materials in facilitating bone regeneration. We focus on the manipulation of fibrin composition and on the recent developments of fibrin composites in enhancing osteogenesis and angiogenesis for bone healing.

Published: August 2022

Introduction: In this study, the performance of computed tomography lung image segmentation using image processing and Markov Random Field was investigated. Before cancer segmentation and analysis, lung segmentation is an important initial process. Thus, the aim of this study is to find the optimal Markov Random Field setting for lung segmentation. Methods: The Centre for Diagnostic Nuclear Imaging at UPM provided 11 anonymous sets of cancerous lung CT images for this study. The thresholding technique is an effective method for medical image segmentation when the priori information for the region of interest is known, such as the Hounsfield Unit value of lung. Due to the large differences in grey levels in the image, the thresholding approach is difficult to apply in segmentation, especially for lung. Thus, for the segmentation process, this study used multilevel thresholding with Markov Random Field with three settings; Iterated Condition Mode, Metropolis algorithm, and Gibbs sampler. The images then went through image processing procedures which were binarization, small object removal, lung region extraction and lung segmentation. The output from the experiments were analyzed and compared to determine the ideal lung segmentation setting. Results: The Jaccard index average values; Markov Random Field -Metropolis = 0.9464, Markov Random Field -ICM = 0.9499 and Markov Random Field -Gibbs = 0.9512. The Dice index average values; Markov Random Field - Metropolis = 0.9743, Markov Random Field - ICM = 0.9724 and Markov Random Field - Gibbs = 0.9749. Conclusion: Markov Random Field using Gibbs sampler delivered the best results for lung segmentation.

Introduction: Oral Squamous Cell Carcinoma (OSCC) represents approximately 96% of the entire oral cancers. Epithelial-mesenchymal transition (EMT) is a factor contributing to the poor prognosis associated with OSCC. α-mangostin is one of the xanthones which show anti-cancer activities against some types of cancers and can suppress EMT-induced invasion by increasing E-cadherin expression. This study aimed to identify the viability of α-Mangostin to reduce the viable cells of HOC313. Methods: The role of α-mangostin to induce HOC313 cell culture at various concentrations which conducted on two groups: control group using only HOC313 cell line and intervention group comprising HOC313 cell line which added various concentrations. In this present study, cells were treated after reaching the confluency level of 80% in 5x103 cells/well. α-mangostin used had six concentrations: 1.25 µM, 2.5 µM, 3.75 µM, 5 µM, 6.25 µM, and 7.5 µM. Results: Concentration of α-mangostin had a significant effect on cell viability, p-value obtained was at 0.023 (p < 0.05). The Mann-Whitney test was also performed to identify significant differences in cell viability between control cells and all treatment cells were at 2.5 mg/ml and 5 mg/ml with the value p = 0.02 (p < 0.05). The concentrations α-mangostin at 1.25, 2.5, 3.75, 5, 6.25, and 7.5 µM is unable to reduce cell viability of HOC313. Conclusion: Low α-mangostin concentrations possibly result in a biphasic effect which leads to increase the viability cell of HOC313 cell line. Therefore, high α-mangostin concentrations might effectively inhibit cancer cell growth, migration, and invasion.

Purpose: The advent of information and communication technology has brought to the front burner the need for students and teachers alike to master the craft of keyboarding. This study investigates the effects of demonstration strategy and computer aided instruction on students’ acquisition of keyboarding skills in colleges of education in South-west, Nigeria.

Methodology: Quasi experimental research was adopted for the study. Specifically, the pre-test, post-test non-equivalent control group design was used. The population consisted of 1,729 NCE one business education students in 11 public colleges of education in South-west, Nigeria. The sample size comprised 620 NCE one students out of which 582 (94%) participated fully in the study. Simple random sampling technique was adopted and intact classes were used as experimental and control groups. The instrument for data collection was Keyboarding Skill Acquisition Test (KSAT) developed by the researcher and validated by four experts. The reliability of the instrument was determined using Spearman Rank Order Correlation which yielded a coefficient of 0.80. The instrument was administered as pre-test to both experimental and control groups. The treatment was applied for six weeks after which the post-test was administered. Mean and standard deviation were used in answering the research questions while Analysis of Covariance (ANCOVA) was used to test the hypotheses at 0.05 level of significance. The results were presented in tables.

Findings: Findings revealed that teaching with computer aided instruction (mean = 53.69, SD = 9.47) had a significant higher positive effect on students’ acquisition of keyboarding skills than demonstration strategy (mean = 47.87, SD = 11.04) and lecture strategy (mean = 40.78, SD = 12.56).

Unique contribution to theory, practice and policy: Teaching with demonstration strategy and computer aided instruction have salutary effect on students’ acquisition of keyboarding skills but computer aided instruction is more effective in the teaching and learning of keyboarding and similar business education skills than other strategies. Therefore, business educators should always endeavour to teach keyboarding with computer aided instruction to improve students’ learning outcome in tertiary institutions.

Pengaruh Konflik Muhammadiyah Dan Haji Misbach Terhadap Pergerakan Muhammadiyah di Surakarta (1922-1926)
Authors: Setyorini Fitri Sari
Published: August 2022

This paper discusses the history of Haji Misbach's conflict with Muhammadiyah and its influence on the Muhammadiyah movement in Surakarta. This research uses the historical method with literature review. The sources used are archives, books, journals, newspapers. Historical and sociological approaches and conflict theory are used as analytical blades on the topic of discussion. The conflict between Haji Misbach and Muhammadiyah shows that: First, the conflict that occurs is due to differences of opinion related to the terminology of true Islamic attitudes. Second, the impact of the conflict on the Muhammadiyah movement in Surakarta from 1922 to 1926 was that Muhammadiyah Surakarta became the first organization to reject communism because it was considered to be damaging to Islamic unity. To strengthen this, Muhammadiyah Surakarta made several agendas of struggle that could suppress the development of communism. Muhammadiyah Surakarta established communist ideology both nationally and communist Islam as the enemy of the Muhammadiyah modernist movement. Muhammadiyah rejected political movements that could threaten the development of Islamic unity in the Dutch East Indies.

In non-infectious diseases in fish, neoplasms are of great interest to pathologists because of their similarity to those found in other vertebrates, some of which are generated by similar carcinogens, such as hepatocellular carcinoma (HCC), induced by chlorinated compounds, algae toxins, and mycotoxins. We have studied 100 specimens of Odontesthes bonaerensis coming from a highly eutrophic lake, San Roque Lake, in Argentina. Hepatomegaly was macroscopically observed in 24 specimens, with external irregular nodular lesions, necrotic, and hemorrhagic areas. The neoplasms were classified according to the WHO for human HCC, in which 20 neoplasms presented a histopathological pattern of the conventional HCC type. Among the neoplasms, four presented a histopathological pattern of sarcomatoid HCC. In the immunohistochemistry, both Hep Par 1, CD34, CD133, and S100 antibodies were positive in all types of HCC and the transmission electron microscopy analysis revealed an ultrastructure similar to that described in the literature for mammalian and human HCC. The etiology of these HCC could not be confirmed, but taking into account the chronic presence of cyanobacteria with frequent algal blooms, we suggest that they are responsible for these neoplasms, especially considering the hepatic carcinogenic activity of algae peptides such as microcystin.

O presente artigo trata sobre proteção aos direitos da criança e do adolescente migrantes contra a exploração do trabalho infantil e busca entender como o sistema normativo brasileiro assegura a proteção aos direitos de crianças e adolescentes migrantes contra a exploração do trabalho infantil. O objetivo geral deste artigo é analisar a garantia dos direitos da criança e do adolescente migrante em face da exploração do trabalho infantil, e seus objetivos específicos são descrever os fundamentos teóricos e jurídicos que embasam os Direitos da Criança e do Adolescente, analisar a proteção jurídica nacional e internacional da criança e do adolescente migrante e sistematizar os instrumentos jurídicos de proteção de crianças e adolescentes migrantes contra a exploração do trabalho infantil. O ordenamento jurídico brasileiro prevê dispositivos de proteção e garantia dos direitos da criança e do adolescente. Tais direitos são postulados na Constituição Federal de 1988, no Estatuto da Criança e do Adolescente, além de legislação esparsa e adoção de tratados internacionais. Estas normas também preveem ações e programas de efetivação destes direitos e de combate à exploração do trabalho infantil.

Os Estados facilitam o deslocamento de pessoas nas fronteiras, acarretando, por consectário, problemas transnacionais, a exemplo de crimes. Para solucioná-los, a cooperação jurídica internacional se afigura como um meio possível. Perquire-se, assim, assimilar como ocorre a cooperação jurídica internacional, em matéria policial penal, na região da tríplice fronteira Brasil, Argentina e Paraguai. São captadas compreensões de cooperação jurídica internacional, fronteira(s) e cooperação policial internacional, para que se apreenda como são executadas na tríplice fronteira Brasil, Argentina e Paraguai. Chegou-se a resultados como a existência de diversos instrumentos de cooperação jurídica internacional para solução de entraves criminais transfronteiriços, sendo a principal a cooperação policial internacional efetivada por intermédio de tratados, resoluções e acordos, em que se preveem procedimentos de eficiente resolução de delitos. Ainda, concluiu-se que o Comando Tripartite da Tríplice Fronteira é um novo mecanismo de cooperação, que, embora não previsto na legislação infraconstitucional nacional, está de acordo com os ditames constitucionais, com o intuito de fiscalizar, prevenir e reprimir delitos embora ainda esbarre em obstáculos burocráticos.
An Economic Analysis of Solid Waste Management in Sivagangai District
Authors: Dr. R. Karthiga Rani
Published: August 2022

Solid waste management planning is a very critical and problematic concern of urban and semi-urban areas. The environmental problem and health hazards are the most prominent consequences of the improper of solid waste management. In Sivagangai district, door-to-door collection and segregation of the wastes are performed. The wastes are segregated either at source or at the compost yard manually. The collected wastes are transported by the tractor with a net cover. Finally, the collected wastes are disposed of in open dumpsites or in landfills. In the present study 38 Panchayats were selected from Sivagangai district which were among 2,000 selected Panchayats across the State. Environment guards in the name of Thooimai Kavalars were appointed for the implementation of the solid waste management programme in these districts. The analysis of the data on Thooimai Kavalars reveals that the appointment of Thooimai Kavalars is not proportional to the number of households in different village Panchayats. Therefore, to improve environmental cleanliness the appointment of Thooimai Kavalars should be in proportional to the number of households in the habitats. In addition, it has been observed that nearly 30% of the solid wastes generated were not cleared and stay on the street corners and temporary dump yards. To clear these wastes contribution by the generators in terms of willingness to pay is inevitable. In the study area, it has been estimated the required amount of contribution interns of willingness to pay to completely remove all the generated wastes is Rs. 300/- per annum. The yearly rate of willingness to pay this will certainly improve the employment chances not only in Sivagangai district but also nationally.
