Authors: ĐỖ VIẾT PHƯƠNG
Published: March 2023

Vỏ quả cà phê là một trong những nguồn phụ phẩm nông nghiệp dồi dào ở Việt Nam. Trong vỏ quả cà phê, cellulose chiếm một hàm lượng lớn, đây là thành phần quan trọng trong việc chuyển đổi thành ethanol sinh học. Tuy nhiên, để có thể chuyển đổi vỏ quả cà phê thành ethanol thì trước hết nguyên liệu này cần phải qua bước tiền xử lý nhằm làm giảm lượng lignin và hemicellulose mà vẫn giữ lại thành phần cellulose. Trong nghiên cứu này, chủng nấm gây mục trắng Phanerochaete chrysosporium được sử dụng để thực hiện quá trình tiền xử lý trước khi quá trình thủy phân và lên men diễn ra. Tại điều kiện độ ẩm nguyên liệu 85%, nhiệt độ môi trường 35oC, tỷ lệ sinh khối/nguyên liệu là 1,5%, sau 40 ngày tiền xử lý  cellulose giảm 20,7%; hemicellulose giảm 12,8% và lignin giảm 50,2%. Nguyên liệu sau khi tiền xử lý tiếp tục thực hiện quá trình thủy phân bởi tổ hợp enzyme thương mại (25 FPU/g Viscozyme Cassava và 34 CBU/g Novozyme 188). Kết quả thu được hàm lượng đường khử và đường glucose trong dịch thủy phân tương ứng là: 13,19 g/L và 5,42 g/L, đồng thời hiệu suất thủy phân đạt 60,23%. Nghiên cứu này chỉ ra rằng, chủng nấm gây mục P. chrysosporium có tính tương thích cao khi phát triển mạnh trên nguồn sinh khối vỏ quả cà phê đồng thời chúng đã tiết ra môi trường một số enzyme giúp phân hủy sinh học cellulose, lignin và hemicellulose.

Authors: Wei Yazhi , Dai Liping , Deng Yanqun , Ye Zhizhong
Published: March 2023

Objectives: This study aims to explore the mechanism by which long non-coding ribonucleic acids (lncRNA) X-inactive specific transcript (XIST) affects the progression of adjuvant-induced arthritis (AIA).

Materials and methods: Freund's complete adjuvant was used to induce arthritis in rats. The polyarthritis, spleen and thymus indexes were calculated to evaluate AIA. Hematoxylin-eosin (H&E) staining was used to reveal the pathological changes in the synovium of AIA rats. Enzyme-linked immunosorbent assay (ELISA) was performed to detect the expression of tumor necrosis factor-alpha (TNF-α), interleukin (IL)-6 and IL-8 in the synovial fluid of AIA rats. The cell continuing kit (CCK)-8, flow cytometry, and Transwell assays were used to assess the proliferation, apoptosis, migration and invasion of transfected fibroblast-like synoviocytes (FLS) isolated from AIA rats (AIA-FLS). Dual-luciferase reporter assay was performed to verify the binding sites between XIST and miR-34b-5p or between YY1 mRNA and miR-34b-5p.

Results: The XIST and YY1 were highly expressed, and miR-34a-5p was lowly expressed in the synovium of AIA rats and in AIA-FLS. Silencing of XIST impaired the function of AIA-FLS in vitro and inhibited the progression of AIA in vivo. The XIST promoted the expression of YY1 by competitively binding to miR-34a-5p. Inhibition of miR-34a-5p strengthened the function of AIA-FLS by upregulating XIST and YY1.

Conclusion: The XIST controls the function of AIA-FLS and may promote the progression of rheumatoid arthritis via the miR-34a-5p/YY1 axis.

Objectives: This study aims to investigate skeletal muscle architecture and strength in patients with primary Sjögren syndrome (pSS).

Patients and methods: Between July 01, 2017 and November 30, 2017, 19 pSS patients (19 females; mean age: 54.1±6.6 years; range, 42 to 62 years) and 19 age-, body mass index-, and sex-matched healthy controls (19 females; mean age: 53.2±6.7 years; range 42 to 61 years) were included. Sjögren symptoms were assessed with the European Alliance of Associations for Rheumatology (EULAR) Sjögren’s Syndrome Patient Reported Index (ESSPRI). Muscle thickness, pennation angle, and fascicle length were measured at quadriceps femoralis, gastrocnemius and soleus muscles. Isokinetic muscle strength tests were performed at 60 and 180°/sec for knee and at 30 and 120°/sec for ankle. Anxiety and depression evaluated with the Hospital Anxiety and Depression Scale (HADS), fatigue with Multidimensional Assessment of Fatigue scale (MAF), and functionality with Health Assessment Questionnaire (HAQ).

Results: In the pSS group, the mean ESSPRI was 7.70±1.17. The mean scores of depression (10.05±3.09 vs. 4.47±2.29; p<0.0001), anxiety (8.26±4.28 vs. 3.79±2.42; p<0.0001), functionality (0.94±0.78 vs. 0.22±0.26; p<0.0001), and fatigue (37.69±5.47 vs. 17.69±5.26; p<0.0001) were significantly higher in patients with pSS. Only, the pennation angle of vastus medialis in dominant leg was significantly greater in healthy controls (p=0.049). Peak torques/body weight of knee and ankle muscles were found to be similar.

Conclusion: Excluding a minor decrease of the pennation angle at vastus medialis, muscle structure of lower extremity of pSS patients were similar to healthy controls. In addition, isokinetic muscle strength did not significantly differ in patients with pSS compared to healthy controls. In patients with pSS, disease activity and fatigue level were negatively correlated with isokinetic muscle strength measurements.

English-language advertising discourse today is undergoing significant improvement and changes. This is due to the transition to online modes, where a person's personality is manifested through the criteria of affection, awareness and attractiveness. However, the negotiation system of a separate feature of the English-language (appearance, manner, knowledge and application of business etiquette) discourse is subject to improvement and practice. If before the transition to the online mode, the tools, means and methods of English-language advertising discourse were worked out, then with the transition to the digital dimension, they require clarification, explanation, adaptation, excluding audio technical transmission channels. The purpose of the study is to outline the main directions in which the developed tools of the English-language advertising discourse are transformed. The methodology was statistical research, which analyzed the appearance of a person in English-language advertising discourses, taking into account forms and types. An approach was also used in which a comparison of a person's appearance was made, taking into account the advertising slogans of foreign companies, as well as various segments in which the analyzed companies operate. As a result of the study, a significant influence of English-language constructions and techniques was noted in comparison with various external images of a person. A theoretical mechanism for the formation of modern English-language advertising discourse is proposed. In general, a list of priority effective means and forms in the formation of modern English-language advertising discourse has been revealed.

Published: March 2023

The use of computer-based information systems today has been understood by most companies in order to survive and succeed well. The transaction processing system (TPS) is a computerized system that runs and records daily routine business transactions that serve the operational level in the company. Information systems of purchase, inventory, sales are part of the TPS widely used by companies. The problem here is how to ensure that the system is connected to the organization's business plan and information requirements, where often a system that is built is not in accordance with the wishes of the user. Meanwhile, manual information systems can cause problems such as data redundancy, inconsistent data, irregular recording, miscalculations, difficulty in finding data and delays in presenting reports. To build the information system, the Framework for the Application of System Thinking (FAST) method will be used with a Rapid Application Development (RAD) approach that uses selected prototype features. The solution is expected to build an information system that can bring together user requirements and help companies process purchase, inventory and sales data in an integrated manner, so as to increase the efficiency and effectiveness of retail data processing.

Published: March 2023

The existence of clean water is very important considering the very dynamic activities of people's lives. Therefore, the quality and quantity must be considered. Clean water that meets health requirements must be free from pollution and must meet quality standards: one of them is physical requirements because drinking water that does not meet quality standards can cause health problems. The topography of an area can affect groundwater in that area. This study aims to analyze differences in the quality of well water in the highlands of Rantauprapat City and the lowlands of Rantauprapat City based on physical parameters. The research was conducted at the BTKL Physics Laboratory in Medan in October 2022. The method in this research was observational analytic with a cross-sectional approach. The sample was determined by purposive sampling which amounted to 50 samples. Data were analyzed using SPSS 21 and the Mann Whitney-U Test.

The morbidity rate of the rural population is lower than that of the urban population for all classes of diseases, which is due to the low availability of medical care (MC) for rural residents, including those with diseases of the skin and subcutaneous tissue (DSST). The purpose of our study was to study the accessibility of MP to the rural population of the Republic of Bashkortostan with DSST and determine ways to improve it.

Materials and methods. An analysis was made of the incidence of the rural population of DSST, resource provision of dermatovenereological care and the volume of primary health care and specialized, including high-tech MC, based on reporting data for the Republic of Bashkortostan (RB) in comparison with the indicators of the Russian Federation (RF) and the Volga Federal District (VFD).

Results. For the period 2013–2020 in the RB, there are high average annual incidence rates of the rural population with DSST, exceeding similar data for the RF and VFD. The provision of dermatovenerologists has decreased (the rate of decrease is 16.2 %), the number of dermatovenereological rooms has decreased (the rate of decrease is 9.3 %). In terms of the number of dermatological beds, the republic ranks frst among other regions of the VFD, and second in terms of the level of provision. The share of rural residents who received high-tech MC in 2020 amounted to 38.5 % of the total quota.

Conclusion. As a result of the study, the need to increase the role of nursing staﬀ of central district hospitals in conducting dispensary observation of patients with chronic dermatoses, creating algorithms for constant interaction between dermatovenereologists of the consultative and diagnostic department of the Republican dermatovenerologic dispensary and doctors and / or nurses of districts, creating a republican register of patients with chronic dermatosis, increase in the volume of high-tech medical care with the use of genetic engineering biological therapy. The priority in increasing the availability of medical care for the rural population with DSST is systematic work consisting in the development and implementation of a set of organizational solutions.
Co-digestão de biomassa residual de microalga com água residuária do processamento do café
Authors:   , Nascimento Larissa Almeida
Published: March 2023

A co-digestão de microalgas brutas, bem como os resíduos e matérias-primas ricas em carbono aparenta ser interessante para melhoria do processo de digestão. Nesse sentido, este trabalho objetivou o estudo da co-digestão da ARC e a biomassa de Scenedesmus obliquus bruta (MB), rompida (MR) e após a extração de proteínas (MPE). Para isso, também foram feitas a caracterização dos substratos, bem como a análise sinérgica e cinética. A ARC apresentou 92% da demanda química de oxigênio (DQO) na sua forma dissolvida e pH de 4,2. Por outro lado, as biomassas detinham pH de cerca de 9,5. Para MB, 3,9% da DQO estava na forma solúvel, sendo que o rompimento permitiu um aumento de 15% do teor DQO solúvel em MR. MPE apresentou menores valores de matéria orgânica em forma de DQO, uma vez que o processo de extração de proteína removeu também outros compostos, além de proteína. A maior produção acumulada de CH 4 foi para a mono-digestão de ARC de 343,3 mL CH4 g SV-1 . Na co- digestão, as produções acumuladas de metano variaram entre 269,6 a 116,4 mL CH4 g SV-1 (65 a 75% do biogás). O rendimento de metano decresceu à medida que a quantidade de microalgas (MB, MR e MPE) presente na mistura aumentou. Por outro lado, a adição de microalgas proporcionou uma melhora na relação AI/AP em comparação com os testes de mono-digestão. O efeito sinérgico foi observado apenas evidenciado nos tratamentos ARC:MB (50:50) e (25:75). As digestões de microalgas atingiram os menores rendimentos: 18,2 mL CH4 g SV-1 para MB, 70,6 para MR e 39,6 para MPE, porém com biogás com teores de metano de 90%. No estudo cinético da digestão anaeróbia (DA), verificou-se um melhor ajuste dos resultados observados com o modelo tipo Cone. Além disso, na co-digestão com MPE não se observou efeito expressivo sobre o coeficiente cinético k h , com resultado de 1,0 e 1,3 vezes superior que a mono-digestão da ARC e MPE, respectivamente. Nos ensaios de co-digestão da ARC com MB e MR, os resultados de k h foram superiores, em média, 1,2 e 2,7 vezes à mono-digestão da ARC e microalgas, respectivamente. As condições alcalinas promoveram um enriquecimento do biogás. Além disso, as análises sugerem que a co-digestão contribui para a alcalinidade da DA da ARC e o aumento da biodegradabilidade das microalgas. Por outro lado, o efeito dos processamentos das microalgas foi menos evidente quando aplicadas como co-substrato do que na mono-digestão. Palavra-chave: Extração de proteínas. Biodegradabilidade. Efluente do café.
