(1) Background: Immune cell therapy recently attracted enormous attention among scientists as a cancer treatment, but, so far, it has been poorly studied and applied in Vietnam. The aim of this study was to assess the safety of autologous immune cell therapy for treating lung, liver, and colon cancers—three prevalent cancers in Vietnam. (2) Method: This was an open-label, single-group clinical trial that included 10 patients with confirmed diagnosis of colon, liver, or lung cancer, conducted between March 2016 and December 2017. (3) Results: After 20–21 days of culture, the average number of cytotoxic T lymphocytes (CTLs) increased 488.5-fold and the average cell viability was 96.3%. The average number of natural killer cells (NKs) increased 542.5-fold, with an average viability of 95%. Most patients exhibited improved quality of life, with the majority of patients presenting a score of 1 to 2 in the Eastern Cooperative Oncology Group (ECOG) performance status (ECOG/PS) scale, a decrease in symptoms on fatigue scales, and an increase in the mean survival time to 18.7 months at the end of the study. (4) Conclusion: This method of immune cell expansion met the requirements for clinical applications in cancer treatment and demonstrated the safety of this therapy for the cancer patients in Vietnam.

Listening is a crucial language skill to be mastered in order to obtain success in not only one’s academic but daily life. However, the limited time of in-class learning may possibly hinder EFL learners’ acquisition and make them lack opportunities to express their ideas freely and creatively. For that matter mentioned, the purpose of this current research was to investigate the EFL learners' attitudes towards the use of Flipped Classroom model in learning listening skills. To this aim, 18 learners were selected and then assigned into a group for experiment. The Flipped Classroom model was introduced and applied into teaching to the students for the same listening course content. The results from the analysis of the questionnaire data revealed that the students had positive attitudes towards the use of Flipped Classroom model in learning listening skills. From these findings, pedagogy suggestions are discussed to further the use of this model in teaching.

Care of the self, according to Michel Foucault, is the practice of coming back to one’s soul and construct the truth of self. While in ancient times, people cared for themselves by writing in hupomnemata, in our modern times, we use social network sites (SNSs) or social media. These digital platforms have provided users with many technological advantages to conduct the online care of self. Sharing a post, posting a status, tweeting a photo or video, replying to a friend’s comments, or revising stories stored in their virtual timeline is one of many self-care acts in a virtual space. However, these advantages of digital technologies accompany with the challenges of losing freedom or being supervized by algorithms whenever individuals engage in social media. This paper tries to answer the question that how modern practices of hupomnemata and care for self, are supported and manipulated by social media’s algorithms. The paper is expected to contribute a new understanding of the self and care for the self in contemporary social media engagement.

This paper presents the preliminary results on the removing capasity of nitrogen and phosphorus in pig wastewater after anaerobic (biogas) process at pilot scale by using Eichhornia crassipes. The experimental results showed that the wastewater loading rate 50 l/m 2 .day with initial concentrations of 89.79 mgTN/l and 15.69 mgTP/l gave removal efficiency of 65.79% và 55.19%, respectively, while the wastewater loading rate 100 l/m 2 .day has removal efficiency of 39.70 % for TN and 43.29% for TP in case of input concentrations 100.38 mgTN/l and 12.52 TP/l. Thus, at the loading rate 50 l/m 2 .day, the removed quantity of TN and TP was of 2,953.64 mgTN/m 2 .day và 432.96 mgTP/m 2 .day, while at the loading rate 100 l/m 2 .day, this value was 3985.09 mgTN/m 2 .day và 541.99 mgTP/m 2 .day. The obtained results indicated that the surface flow wetland system, using Eichhornia crassipes has a rather high TN and TP removal efficiency at simple operation so that it could be feasible if applied for treating pig wastewater. However, the system should be functioned longer for taking data and for evaluating it's stability.

At present, quantitative fluorescent - polymerase chain reaction (QF-PCR) technology is widely being used in prenatal diagnosis of some common genetic syndromes such as Down syndrome, Patau syndrome and Edwards syndrome. The advantages of this technique are its high accuracy, rapid test results and wide applicability. It has used this technique to detect AZF (Azoospermia factor) micro-deletions by Devyser's kit at Tu Du Hospital, Ho Chi Minh City. The novelty of the study was to create a kit with 14 genetic markers and to develop a QF-PCR protocol to detect some common genetic causes in men seeking medical for their infertility with the sperm concentration of ≤ 5 million/ml. We conducted an evaluation in reliability in order to confirm whether the QF-PCR results from the set-up protocol were accurate and reliable. We developed the research on the application of QF-PCR to test for the DNA samples of patients. They were 10 normal reproductive men, 2 patients with Klinefelter syndrome, 4 patients with AZFc micro-deletions, 1 female with normal reproduction. Cordially, we used a sample of water to control the experiment. The results have shown that the kit with 14 genetic markers and the built-in QF-PCR protocol for detecting some common genetic causes in men seeking medical care for their infertility were accurate 100% compared to multiplex-PCR and peripheral blood lymphocyte cultures. The study results are important for identifying some common genetic causes in men seeking medical care for their infertility and helping doctors build the most inferior treatment regimens for their patients.
