Primary myelofibrosis is the severe form of myeloproliferative neoplasms that causes scar tissue in the bone marrow, leading to low production of blood cells and thus, life span shortening. Besides the most common variant JAK2 V617F, the association between these disorders with other variants in the JAK2 gene, especially the exon 12 variants have been poorly studied. In our research, the JAK2 exon 12 variants were detected by amplification and sequencing from genomic samples of five cases with V617F-negative primary myelofibrosis.
Breast cancer is the most frequently diagnosed cancer in women globally. The tumor microenvironment plays a vital role in epithelial-to-mesenchymal transition (EMT), leading to the invasion and metastasis of cancer cells. The tumor microenvironment includes all components of the tumor cells, including the extracellular matrix, tumor vasculature, mesenchymal stem cells, immune cells, and fibroblasts. Understanding the interactions between mesenchymal stem cells and cancer cells is essential in determining the role of mesenchymal stem cells in diagnosing and treating breast cancer.
Breast cancer is the most frequent female cancer, and it is increasing at an alarming rate. The typical symptom of breast cancer is breast lumps or swellings, though they can also develop close to the breast or under the arm. Breast cancer usually spreads to distant organs such as the bone, liver, lungs, and brain. Approximately 95% of breast cancer patients who arrive with the early-stage disease show no macroscopic signs of metastases. Although it is possible to reduce some breast cancer risks through prevention, the majority of patients in low-income countries are detected at a late stage. Because of this, even though current therapy is improving, early diagnosis is still crucial for improving the quality of treatment and the survival rate. Sex, age, family history, and an unhealthy lifestyle are some of the risk factors that may increase the chances of getting this disease. Familial or hereditary breast cancer accounts for 10% of breast cancers. Mutations in the BRCA1 and BRCA2 genes were responsible for 50% of all familial or hereditary breast cancer cases. In this research, mutations in a Vietnamese patient with familial breast cancer were analyzed using whole exome sequencing.
Anacardic acid accounts for approximately 77% of the cashew nut shell liquid from Anacardium occidentale, which was reported to have anticancer potential. Due to its water insolubility, the compound is hard to absorb leading to less bioavailability. Currently, using nanolipsomes as drug carriers in general and for anacardic acid in particular could be an effective solution. In this research, anacardic acid was incorporated into nanoliposomes by employing the thin-film method.
In this study, four MDV-1 (GaHV-2) strains causing the disease in Bac Ninh province during the 2019–2022 period were identified by multiplex Polymerase Chain Reaction (PCR). Subsequently, the segments of 1020 bp encoding 339 amino acids of Meq gene (Marek’s disease virus EcoRI fragment Q) from four samples were collected and sequenced. Overall, this study provides valuable information on molecular characteristics of MDV-1 strains in Bac Ninh province during the 2019–2022 period.
This study aimed at identifying resistome and plasmidomes carrying antibiotic-resistant genes (ARGs) in an extensively drug-resistant extra-intestinal pathogenic E. coli strain XP817 isolated from a one-year-old child with respiratory distress syndrome. Whole genome analysis of strain XP817 revealed 68 ARGs documented in the Comprehensive Antibiotic Resistance Database (CARD). In conclusion, our study underlines the crucial role of the ARG dissemination via horizontal gene transfer in E. coli as well as in the Enterobacteriaceae family.
In previous studies, horses were predominantly found to be hosts of Halicephalobus sp. nematodes, but in this study they are not presented in the parks, suggesting that other wild animals such as ruminants in the parks should be their hosts. In addition, we analyzed the 18S rDNA sequences of the isolated nematodes and found that they are likely divergent between the two ecological systems, suggesting the two nematode communities have evolved differently.
The present study focused on analyzing the diversity and distribution of endophytic fungi related to different tissues from samples of the medicinal plant Dysosma difformis (Hemsl & E.H. Wilson) T.H. Wang collected in Ha Giang and Lai Chau, in which the isolates from roots were 27 strains (50.94%), 12 strains from stems (22.64%), and 14 strains from leaves (26.42%). Based on the isolates, we analyzed the fungal diversity through seven different diversity indices. The results showed that isolates’ diversity was similar to the endophytic fungal population in tissues of D. difformis distributed in different vegetation in Vietnam.
