Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.47A009

Sixteen samples of surface and groundwater from the most southern part of the Hanoi city (Vietnam) has been taken and analyzed for the soluble major ions, namely Na+, K+, , Ca2+, Mg2+, Cl-, \"\", and arsenic as well as molybdenum content along with isotopic composition of deuterium and oxygen (δ2H and δ18O), tritium activity, and δ13C in DIC. The stable isotopic composition of groundwater indicates the water in that area is recharged from the local meteoric and theRed River’s water sources. The mean residence time of the groundwater should be before 60-ies of the past century as its 3H activity ranged from LOD of the analytical technique (0.4 TU) to 2.1 TU only implying that As would not be related to its recent application. The concentrations of As in the water samples is weakly correlated with those of Fe2+ (R2 = 0.08) but it strongly did with the concentrations of bicarbonate (R

Straightforward Procedure for Laboratory Production of DNA Ladder

Journal of Nucleic Acids , 2012, DOI: 10.1155/2012/254630
Abstract: DNA ladder is commonly used to determine the size of DNA fragments by electrophoresis in routine molecular biology laboratories. In this study, we report a new procedure to prepare a DNA ladder that consists of 10 fragments from 100 to 1000?bp. This protocol is a combination of routinely employed methods: cloning, PCR, and partial digestion with restriction enzymes. DNA fragments of 100?bp with unique restriction site at both ends were self-ligated to create a tandem repeat. Once being cloned, the tandem repeat was rapidly amplified by PCR and partially digested by restriction enzymes to produce a ladder containing multimers of the repeated DNA fragments. Our procedure for production of DNA ladder could be simple, time saving, and inexpensive in comparison with current ones widely used in most laboratories. 1. Introduction A DNA ladder is a solution of DNA molecules of different lengths used in agarose or acrylamide gel electrophoresis. It is applied as a reference to estimate the size of unknown DNA molecules that were separated based on their mobility in an electrical field through the gel. Thus, DNA ladders are essential molecules routinely used in every DNA dealing laboratory. Digestion with restriction enzymes of known-length DNA fragments from natural sources such as lambda [1], simian virus 40 [2], and plasmid [3] creates the ladder fragments the lengths of which are dependent on restriction enzyme sites thus, not fully controlled. To overcome this disadvantage and to make DNA ladders more flexible, DNA engineering was developed [4]. Perhaps, for commercial purpose, DNA manipulation for producing DNA ladder fragments became confidential. Typically, a DNA fragment that contains a tandem repeat units separated by the same unique restriction enzyme sites was cloned into a plasmid and then partially digested to produce a ladder with multimers of the repeats [5, 6]. However, the more clear visibility of small size fragments requires the higher amount of plasmid used in cleavage reaction. Recently, many laboratory protocols describing the preparation of DNA ladders by employing the polymerase chain reaction (PCR) method have been reported [7–9]. This method involves either the simultaneous amplification of a DNA target using primer sets [8] or the separate amplification of a different DNA targets using specific primers [9, 10]. However, using simultaneous primer sets is often difficult to be reproductive because of problematic optimization of PCR conditions, while using separate primer set for a particular fragment of ladders causes a laborious task.
Evaluation of Landslide Susceptibility in Cau River Basin Using a Physical-Based Model under Impact of Climate Change  [PDF]
Thi Thanh Thuy Le, Seiki Kawagoe
Open Journal of Modern Hydrology (OJMH) , 2019, DOI: 10.4236/ojmh.2019.91001
Abstract: This paper evaluated the probability of landslide susceptibilities through the applica-tion of the Transient Rainfall Infiltration and Grid-Based Region Slope-Stability model in Cau river basin (Vietnam) using the scenarios-based approach under the influence of the warming climate. The tested cases were developed based on various options including rainfall amount and distribution, soil depth determination, and land-cover conditions. Input data for extreme rain events included historical rainstorm in 2013, the Probable Maximum Precipitation (PMP) with the durations of 24 hours and 48 hours. The results illustrated the reduction of slope stability when the land cover changed from land-use data in 2007 (Ha12) to land-use data in 2015 (Ha22). When the whole region was assumed to be replaced by soil (Ha02), the factor of safety (Fs) decreased to lower magnitude when compared to Fs value regarding to changes in land cover condition (Ha12 & Ha22) and changes in soil-depth (Ha33). The model simulations demonstrated the agreement with the slope-failure hazard association with the destabilizing factor such as slope-cutting activities at historical landslide events. Under the same land-cover and soil depth condition, the average value of factor of safety regarding to the historical rainstorm in 2013 (Ha32) declined by 0.069 and 0.189 when compared to Fs of the 24-hour PMP with the storm distribution type 3 (1332) and Fs of the 48-hour PMP with the storm distribution type 3 (2332), respectively. The results reveal that in a warming climate, changes in extreme precipitation in terms of rain-total, rain-duration, and rain-distribution would result in the expansion of slope instability in the hilly region. This application is considered as a prevailing method for landslide susceptibility analysis and would provide important information for authorities in developing adequate land-management in the river basin.

Abstract: Background Awareness of individuals’ knowledge and predicting their behavior and emotional reactions is crucial when evaluating clinical preparedness for influenza pandemics with a highly pathogenic virus. Knowledge, attitude, and practice (KAP) relating to avian influenza (H5N1) virus infection among residents in communities where H5N1 patients occurred in Vietnam has not been reported. Methods and Principal Findings Face-to-face interviews including KAP survey were conducted in Bac Kan province, located in the northeast mountainous region of Vietnam. Participants were residents who lived in a community where H5N1 cases have ever been reported (event group, n = 322) or one where cases have not been reported (non-event group, n = 221). Data on emotional reactions of participants and healthcare-seeking behavior after the event in neighboring areas were collected as well as information on demographics and environmental measures, information sources, and KAP regarding H5N1. These data were compared between two groups. Higher environmental risk of H5N1 and improper poultry-handling behaviors were identified in the event group. At the time of the event, over 50% of the event group sought healthcare for flu-like symptoms or because they were scared. Awareness of the event influenced KAP scores. Healthcare-seeking behavior and attention to H5N1 poultry outbreaks diminished in the event group as time passed after the outbreak compared with the non-event group. Factors that motivated participants to seek healthcare sooner were knowledge of early access to healthcare and the risk of eating sick/dead poultry, and perception of the threat of H5N1. Conclusions Awareness of H5N1 patients in neighboring areas can provoke panic in residents and influence their healthcare-seeking behavior. Periodic education to share experiences on the occurrence of H5N1 patients and provide accurate information may help prevent panic and infection and reduce mortality. Local conditions should be taken into account when emphasizing the need for early access to healthcare.

Abstract: Background Early initiation of treatment is essential for treatment of avian influenza A/H5N1 viral infection in humans, as the disease can lead to rapid development of severe pneumonia which can result in death. Contact with infected poultry is known to be a significant risk factor for contraction of H5N1 infection. However, handling and encountering poultry are a part of most peoples' daily lives, especially in rural communities in Vietnam where epidemic outbreaks among poultry have been continuously reported. Enhancing proper knowledge relating to H5N1 and to the importance of early initiation of treatment are crucial. The aim of this study was to develop an effective educational program to enhance awareness of H5N1 and motivate people to access to health care earlier when H5N1 infection is suspected or likely. Methodology and Principal Findings A study was conducted in two agricultural communities (intervention and control groups) in the Ninh Binh province in Vietnam, where epidemic outbreaks of avian influenza have recently occurred in birds. A unique educational intervention was developed and provided to the intervention group, and no intervention was provided to the control group. A knowledge, attitude and practice (KAP) survey was conducted in both groups with a face-to-face interview by trained local healthcare workers at time points before and after the educational intervention. KAP scores were compared between the different time points and between the groups. How educational intervention influenced awareness relating to H5N1 and accessibility of healthcare in the population was analyzed. The study indicated an increased awareness of H5N1 and increased reliance on local health care workers. Conclusions The novel educational program which was developed for this study impacted awareness of H5N1, and resulted in more people seeking early access to healthcare, and also resulted in earlier medical intervention for patients with H5N1 avian influenza infection in Vietnam.

Breast cancer (BC) is the second incidence and the fifth leading cause to cancer death in the worldwide. In developing countries, the number of BC cases is still increased annually accompanied with the changes of lifestyle and screening programs. Nevertheless, the majority of BC patients are diagnosed as non-curative stage. Thereby, systemic therapy always plays an important role in BC treatment strategies. Among chemotherapy regimens, the combination of anthracyclin and taxane as an adjuvant treatment has been proven the efficacy and safety in terms of prolonging survival. In this study, we evaluated the incidence of chemotherapy-induced amenorrhea in breast cancer patients who were treated with adjuvant anthracycline and taxane-based chemotherapy.

Nguyen Thi Thanh Huong, Nguyen Thi Hoang Thuy, Le Thi Hai Yen
International Journal of Clinical Medicine (IJCM) , 2019, DOI: 10.4236/ijcm.2019.101003
Abstract: Objectives: The study aimed to describe the quality of sleep and explore factors especially Sleep Hygiene Practices associated with sleep quality among pregnant women. Study design: This is a cross-sectional study. Methods: 119 healthy pregnant women in two central hospitals in Vietnam were participated in this study. The Pittsburgh Sleep Quality Index (PSQI) was employed to evaluate sleep quality and the Modified Sleep Hygiene Practices was used to describe sleeping practices among pregnant women. Results: The results showed that while 58.8% pregnant women had quite good sleep quality, 41.2% of pregnant women had mild to moderate quality sleep disturbance. The quality of sleep was better in second trimester, but then getting worst in the third trimester. Multipara experienced worse sleep quality than nullipara. Poor sleep quality had a positive correlation with unhealthy Sleep Hygiene Practices including using an uncomfortable bed (p < 0.05), going to bed with variable bedtime (p < 0.01), watching TV or making call in bed other than sleep (p < 0.05), going to sleep without sleep sensation (p < 0.001) and staying in bed even though it was difficult to fall asleep (p < 0.001). Conclusion: Pregnant women should be taken care of on sleep quality, especially in the first and third trimester as they experience more change in hormone and physiology. Sleep Hygiene Practices should be emphasized in health education for pregnant women.

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0034906
Abstract: Background The 2000 Vietnamese National Nutrition Survey showed that the population's dietary intake had improved since 1987. However, inequalities were found in food consumption between socioeconomic groups. As no national data exist on the prevalence of micronutrient deficiencies, a survey was conducted in 2010 to assess the micronutrient status of randomly selected 1526 women of reproductive age and 586 children aged 6–75 mo. Principal Findings In women, according to international thresholds, prevalence of zinc deficiency (ZnD, 67.2±2.6%) and vitamin B12 deficiency (11.7±1.7%) represented public health problems, whereas prevalence of anemia (11.6±1.0%) and iron deficiency (ID, 13.7±1.1%) were considered low, and folate (<3%) and vitamin A (VAD, <2%) deficiencies were considered negligible. However, many women had marginal folate (25.1%) and vitamin A status (13.6%). Moreover, overweight (BMI≥23 kg/m2 for Asian population) or underweight occurred in 20% of women respectively highlighting the double burden of malnutrition. In children, a similar pattern was observed for ZnD (51.9±3.5%), anemia (9.1±1.4%) and ID (12.9±1.5%) whereas prevalence of marginal vitamin A status was also high (47.3±2.2%). There was a significant effect of age on anemia and ID prevalence, with the youngest age group (6–17 mo) having the highest risk for anemia, ID, ZnD and marginal vitamin A status as compared to other groups. Moreover, the poorest groups of population had a higher risk for zinc, anemia and ID. Conclusion The prevalence of anemia and ID in Vietnam has been markedly reduced over the last decade, but a large part of the population is still at risk for other deficiencies such as zinc, vitamin A, folate and vitamin B12 especially the youngest children aged 6–17 mo. Consequently specific interventions to improve food diversity and quality should be implemented, among them food fortification of staple foods and condiments and improvement of complementary feeding.
An Investigation of Perceptions of Vietnamese Teachers and Students toward Cooperative Learning (CL)

International Education Studies , 2011, DOI: 10.5539/ies.v4n1p3
Abstract: The present study examined how cooperative learning (CL) is implemented in Vietnamese classrooms, how local teachers' and students' perceived this approach to learning, and what were the local barriers that hindered its implementation. Forty teachers and forty students from twenty Vietnamese colleges completed a questionnaire about CL and follow-up interviews were conducted with ten students and ten teachers on their perceptions of this practice. The results showed that CL has become a common and preferred method of instruction in Vietnam. However, the functions of CL were often not understood correctly because the teachers and students maintained that CL mainly helped the students remember information rather than develop a deep understanding of the text they were studying. Responses also revealed that CL was hindered by a number of local cultural and institutional barriers such as class size, curriculum coverage and workload division. Future research may need to identify strategies to correct mismatches between CL principles and local barriers so that this approach to learning becomes more adaptive to the local context.
