Polyploidization is one of the most crucial pathways in introducing speciation and broadening biodiversity, especially in the Plant Kingdom. Although the majority of studies have focused only on allopolyploid or disomic polyploids, polysomic polyploid species have occurred frequently in higher plants. Due to the occurrence of the capabilities of more copies of alleles in a locus which can have additive dosage effects and/or allelic interactions, polysomic polyploids can lead to unique gene regulations to silence or adjust the expression level to create variations in organ size, metabolic products, and abiotic stress tolerance and biotic stress resistance, etc. This review aims to comprehensively summarize the contemporary understanding and findings concerning the molecular mechanisms of gene expression as well as gene regulation in natural typed and resynthesized polysomic polyploid plants. The review investigates the molecular level of phenomena in polysomic polyploid plants such as 1) typically enlarging organ size and stabilizing meiosis, 2) increasing phytochemical content and metabolic products, 3) enhancing the ability to adapt with biotic and abiotic stress, and 4) changing in gene regulation to silence or adjust the expression levels involve in sequence elimination, methylation, gene suppression, subfunctionalization, neo-functionalization, and transposon activation.

It is commonly known that polyploidization has become one of major forces for a speciation and evolution, especially with evolutionary fixed potential agronomic traits in plants. Although several studies demonstrate that allopolyploid plants were successful in developing novel crops, autopolyploid ones are also more substantial and worth exploring. Obviously, autopolyploid development via sexual or asexual pathways can lead to advantages in biomass, changing process of development, and lots of benefits on coping with climate changes do not comprehend as a whole. This review shed light on 1) gaining gigantic effect and increasing phytochemical content; 2) enhancing biotic and abiotic tolerance to adapt to climate change; 3) changing in process of development; 4) adapting ecology. Based on these benefits, this review provides breeders with several choices when they need in the breeding strategies. Also further review on prospects of polyploidy potato in food security is concerned.

The Government has promulgated the "Strategy to develop the banking industry in Vietnam to 2025, with orientation to 2030," The strategic perspective on the development of Vietnam's banking system plays an essential role in the financial system. Credit institutions or commercial banks are treated equally, compete following the law, operate autonomously, and take self-responsibility. In the past time, although the human resource of the credit institution system has improved significantly, the Government still sets a requirement to focus on developing human resources of the banking industry to ensure the completion of strategic goals. The article outlines several limitations and inadequacies in human resources of commercial banks, thereby proposing some solutions to develop human resources of commercial banks to successfully implement the development strategy of the banking industry to 2025 and orientation to 2030.

According to the theory of active education and Mathematics teaching in secondary schools, there are five steps designed for geometrical knowledge and four stages for the process of applying the examined circumstances. The research objective aims to evaluate the effectiveness and feasibility of the suggestion focused on the process of constructing and manipulating situations in teaching Geometry. The research method uses the case study in the specific teaching process, which was conducted with 24 teachers who have taught Mathematics at secondary schools over three months from August 2019 to October 2019; and 30 secondary school students between May 2020 and July 2020. Finally, the result shows that all teachers agree that the design and application process is appropriate and effective for their lesson. In terms of the student's aspect, the case study reveals that the application of various steps in the process is beneficial for improving geometric deductive and spatial estimation, as well as using theoretical knowledge in the practical situation. Based on the research, this paper will clarify some solutions related to the way to design processes and utilize them in some Geometry content in secondary schools in Vietnam.

Background: Acromioclavicular (AC) dislocation, one of the most common shoulder joint injuries, can be treated by several surgical methods. However, there are still few records about the treatment quality. This study aims to describe the outcomes of three surgical methods for acromioclavicular dislocation treatment at Viet Duc University Hospital, Vietnam. Methods: A cross-sectional study was conducted on 80 patients diagnosed with AC. We retrospectively collected data in the medical records and re-examined the patients. Results: There was no difference between the three groups of surgical approaches relating to the patient’s characteristics, except for the time from the accident to hospital admission. The median length of stay after surgery was highest in the Hook plate group (median (IQR) = 5(2) days), while it was lowest in the K-wire group (median (IQR) = 3(1) days) (p < 0.05). There is statistical significance in the difference of coracoclavicular distance between pre and post-operation in all three surgical method groups (p < 0.001). Conclusion: All of the methods—Hook plate, K-wire, and TightRope—were associated with optimistic outcomes and restored initial anatomy. While the three surgical methods are both safe and effective, the K-wire method is associated with a shorter length of stay and might be economical.

Hội chứng thực bào máu (Hemophagocytic lymphohistiocytosis - HLH) là một hội chứng lâm sàng hiếm gặp và thường gây tử vong, đặc trưng bởi tình trạng đáp ứng viêm quá mức do hoạt hóa bất thường đại thực bào và tế bào lympho T gây độc tế bào, dẫn đến cơn bão cytokine và tổn thương các cơ quan. U lympho, đặc biệt là u lympho tế bào B, là nguyên nhân phổ biến của HLH thứ phát ở Nhật Bản. Tuy nhiên, ở Việt Nam, hầu hết các trường hợp HLH thứ phát được báo cáo là liên quan đến nhiễm trùng. Ở đây chúng tôi mô tả một bệnh nhân HLH thứ phát do u lympho tế bào B lớn lan tỏa (DLBCL) được điều trị bằng phác đồ R-CHOP. Tất cả các triệu chứng lâm sàng và cận lâm sàng của HLH đều trở về bình thường và u lympho đạt lui bệnh hoàn toàn sau 4 chu kỳ R-CHOP. Tuy nhiên bệnh nhân tử vong do U lympho tiến triển tại não, tủy sống cổ và thắt lưng sau chu kỳ 5. Trường hợp hiếm gặp này không chỉ làm nổi bật khả năng xảy ra HLH thứ phát sau DLBCL mà còn cho thấy tầm quan trọng của việc bắt đầu sớm hóa trị đặc hiệu và dự phòng bệnh tiến triển thần kinh trung ương.
