Predicting housing prices is particularly of interest to many scholars and policymakers. However, are highly volatile difficult predict. This study used both traditional advanced machine learning (ML) approaches address the issue price prediction. involves compares predictive power between ML models, including random forest, gradient boosting, k-nearest neighbors (KNN), bagged classification regression trees (CART), models based on linear its modifications. Notably, in this study, we...
Vitamin A deficiency is one of the major nutritional deficiencies in Vietnam. first survey, conducted 1985–1988 showed that prevalence severe xerophthalmia was seven times higher than cutoff point established by World Health Organization (WHO) to define vitamin as a public health problem. result this survey strongly convinced government launch program control deficiency, which started 1988. strategies included nutrition education, universal distribution high-dose capsules children aged 6 36...
Previous paleoclimatic studies by Asian cave records have shown that variability in the summer monsoons is well correlated with local insolation, North Atlantic climate, and Greenland stadial-interstadial cycles on millennial to orbital time-scales. However, it remains unclear whether a similar agreement exists short timescales. With 230Th dates precision as good ±62 years, we present decadal-resolved δ18O record covering 30.0–22.7 thousand years ago (ka) from stalagmite of Son La Province,...
Abstract Capturing CO2 from stationary sources such as power stations and petroleum processing plants storing the into deep geological formations can potentially reduce greenhouse gas emissions in Australia. The cost of capturing could vary below US$30 to above US$70 per tonne avoided for coal-fired typical used In addition, storage costs US$5 US$20 avoided. These figures are based on pure CO2. other gases addition might lower unit capture significantly. However, this needs be balanced...
This paper presents the variations of rate change Total Electron Content (TEC) index (ROTI), characterizing occurrence ionospheric plasma irregularities over Vietnam and neighboring countries in Southeast Asian region using continuous GPS data during 2008-2018 period. The results showed that strong ROTI all stations is maximum equinox months March/April September/October depends on solar activity. weak periods low activity high There an asymmetry between two equinoxes. During declining...
Background: Direct-Acting Antivirals (DAAs) are recommended as first-line of drugs for the treatment chronic hepatitis C virus (HCV) infection in Vietnam 2016. Since then, Hospital Tropical Diseases (HTD), Ho Chi Minh City, introduced DAAs based all newly presented HCV patients. Here, we report sociodemographic, clinical, biochemical, and virologic characteristics patients direct medical cost associated with treatment. Methods: We conducted a retrospective cross-sectional study among...
Heinrich Event-3 (HE-3) differs from other Events (HEs) in terms of the strength its expression climatic records different global localities. Here, we present new high resolution δ18O a composite speleothem record spanning 31.5 to 28.4 ka within HE-3 time interval. The is obtained two stalagmites collected Thuong Thien cave (TT), northern Vietnam, which exhibit growth rates 0.12 0.68 mm/yr. TT shows pronounced positive excursion values stalagmite interval 30.8 and lasted about one thousand...
Trang phuc linh plus (TPLP) is a food supplement product derived from dried extracts of herbal agents Atractylodes macrocephala, Poria cocos, Paeonia lactiflora, Phellodendron amurense, and added lactobacillus fermentum lysate (ImmuneGamma®) 5-hydroxytryptophan. TPLP functional used as adjunctive treatment for treating irritable bowel syndrome (IBS). However the biological effect its mechanism action in IBS have not been elucidated. In this study, we aimed to determine pharmacological...
The Ba Lat estuary is part of the downstream stretch Red River Delta, second-largest Delta in Vietnam and 12th largest world. This study analyses GAT borehole sediments area to assess environmental changes during Late Pleistocene - Holocene period. entailed detailed 70 m-deep data from area, including structural analysis sediment core samples, 230 samples grain size, 49 Foraminifera, five petrographic thin slices, four radiocarbon dating.
 reveal nine sedimentary facies, river channel...
To clarify the paleoclimatic events in Northern Vietnam during Late Quaternary, 132 Con Moong - Thanh Hoa cave sediment samples were collected to analyze magnetic susceptibility (χ), δ18O, and δ13C. Based on tendency value of χ Moong's sediment, 14 climate zones that change continuously from warm cold identified. These also correspond changing trend δ18O The period is referenced extrapolation four 14C data. alternating cold-warm sequences Composite Reference Section (CRS) developed Southern...
Abstract Background Healthcare utilization is typically adversely affected when the treatment expensive and requires multiple visits. We examined determinants of healthcare-seeking for Hepatitis C virus (HCV) infection which asymptomatic, chronic, costly in an urban tertiary care referral hospital Vietnam. Methods conducted a secondary analysis data patients attending Hospital Tropical Diseases Ho Chi Minh City, Vietnam between 2017 2020 specifically HCV treatment. Poisson regression was...
This paper presents the first observations of occurrence rates Spread F and GPS total electron content (TEC) index (ROTI) over Vietnam at equatorial trough northern tropical crest ionization anomaly in Asian sector. The data have been examined for monthly nighttime variations these two Bac Lieu (9.28°N, 105.73°E, dip: 1.73°N) Phu Thuy (21.03°N, 105.95°E, 14.49°N) during 2023. For Lieu, variation range (RSF) has maxima February, May, September months, while mixed Spread-F (MSF) ROTI...
Isaria cicadae (I. cicadae) and tenuipes tenuipes) are insect parasitic fungi that contain many bioactivites including tumor inhibited activity, anticancer, immune booster. MMP-8 (Matrix Metalloproteinase-8) is one of the collagenases belonging to endopeptidase enzyme family in mammals, related extracellular matrix degeneration, angiogenesis, invasion metastasis. The objective this study conducted investigate metastatic inhibitory activity through restraining collagen resolution using 26...
Matrix metalloproteinases (MMPs) are endopeptidases, they involved in tumor growth, and the processes of invasion metastasis. Cordyceps spp. were recorded to have anticancer potential. In previous studies, extracts from neovolkiana strain DL0004 takaomontana DL0038A capable cytotoxic activity against MCF-7 Jurkat cell lines. this study, 26 prepared biomasses fruit bodies C. DL0038A, then proceed screen for MMP inhibition assay by concentration ranges 2000 µg/mL, 200 20 µg/mL. The results...
Perilla frutescens L. is an edible plant used as a food item well folk medicine for human diseases in some Asian countries. Due to limited studies the extraction of total phenols responsible its high bio-functional properties, this study aimed compare yields, phenolic content (TPC), and antioxidant capacities extracts between pressurized liquid (PLE) at 100°C with or without ultrasonic treatment conventional techniques. A batch mode PLE system was utilized use water 50% aqueous ethanol...
