Abstract
Anacardic acid (AA) is a natural active ingredient that accounts for 65% of the liquid extract from the shell of the cashew nut. Due to the stronger cytotoxic activity of hydrogenated AA (HAA) against NTERA-2 cancer stem cells (CSCs) than AA itself, HAA was co-conjugated with CD133 monoclonal antibody (mAb^CD133) into nanoliposomal particles (AMC). This nanoliposomal complex is expected to improved HAA activities against CSCs based on the targeting capacity of mAb^CD133 toward CD133, a typical CSCs’ surface marker. AMC was manufactured with a mean size of 100.9 nm, a zeta potential of −40.7 mV, and a PDI of 0.283. We report a 100% encapsulation efficiency of HAA into liposomes and a 90.7% conjugation efficiency with mAb^CD133. The penetration of AMC into NTERA-2 CSCs after 2 h was 83.7%. The AMC complex inhibited NTERA-2 growth with an IC50 (inhibition concentration at 50%) value of 75.83 ± 6.70 µM, showing the targeting ability and lower toxicity (IC50 > 100 µM) on healthy cells. The AMC nanoparticles also demonstrated significant potential apoptotic induction by activating caspase 3 activity by up to 2.57 and 2.06 folds compared to that of the negative control at 20 and 4 µM, respectively. This induction was significant improvement in comparison with that of unconjugated HAA ( P < .05). AMC presented a clear effect on the solid structure of NTERA-2 spheroids and significantly suppressed the proliferation of CSCs in the 3D tumorspheres with an IC50 = 64.25 ± 3.15 µM, compared to the free form with an IC50 = 82.22 ± 0.65 µM ( P < .05). Therefore, this nanoliposomal complex exhibits promising capacities as an effective material against NTERA-2 CSCs.

Abstract
Black pepper ( Piper nigrum L.) is widely grown in the Chu-se district of Gia Lai province in Vietnam. The pepper, used as a spice, also serves as a traditional medicine in many countries. Black pepper contains many different substances; the most active of these is piperine, which exerts anti-oxidant, anti-inflammatory, and anti-cancer effects. However, piperine is a poorly absorbed alkaloid, and high concentrations may be toxic. Therefore, its medicinal uses remain limited. Here, we extracted piperine from black peppers collected at Chu Se, created piperine and anti-CD133 monoclonal antibodies (mAb^CD133) containing nanoliposomal complexes (PMCs), and evaluated their inhibitory effects on cancer stem cells (CSCs) in vitro. The physical properties of PMCs showed an approximated diamater of 170 nm, a PDI of 0.23, zeta potential of −9.38 mV, and an encapsulated efficiency of 73.33 ± 9.09%. The PMCs significantly inhibited NTERA-2 cell growth (IC50 = 435.3 ± 4.3 µM), but were not toxic to healthy cells (IC50 >500 µM). The PMCs remarkably affected the CSC surface marker expressed level of which the CD44+/CD133+ population was only 2.12% compared with 21.72% for blank nanoliposomes. The NTERA-2 antiproliferative activities of PMCs might be associated with their G2 cell cycle phase arresting and caspase-3 inducible activities (up to 1.51 times) ( P < 0.05). The nanoliposomal complex also significantly inhibited the proliferation of NTERA-2 cells in three dimensional tumorspheroids with an IC50 = 245.82 ± 11.44 µM and reduced the size by up to 41.50 ± 4.31% ( P < 0.05). Thus, the PMCs proved their enhanced potential biomedical and pharmacological applications in targeted cancer therapies.

Abstract
Recently, saponins derived from marine sources have received much attention because of their promising bioactivities, such as anticancer, anti-angiogenesis, and anti-inflammation. In particular, a triterpene saponin from the sea cucumber Cercodemas anceps Selenka, cercodemasoide A (CAN1), showed potent cytotoxicity against various cancer cell lines. Recent evidence has indicated that cancer stem cells (CSCs) could be a novel target for efficient cancer therapies. In order to improve the biopharmaceutical properties of CAN1, the compound was loaded into nanoliposomes as an ideal drug carrier. CAN1 was successfully incorporated into nanoliposomes as small unilamellar liposome vesicles with an average size of 73.39 ± 1.57 nm, zeta potential of −0.299 ± 0.046 mV, polydispersity index of 0.336 ± 0.038, and with an encapsulation efficiency of up to 62.9%. For the first time, CAN1 and its nanoliposomal forms have been shown to have a promising cytotoxic activity against NTERA-2 CSCs, with half-maximal inhibitory concentration (IC50) =1.03 ± 0.04 and 0.41 ± 0.03 µM, respectively. The CAN1 nanoliposomes also presented significantly improved activities in suppressing the growth of NTERA-2 3-dimensional tumorspheres (IC50 = 1.71 ± 0.06 µM) in comparison with the free form ( P < .05). The anti-CSC effects of CAN1 nanoliposomes on NTERA-2 cells were due to their apoptotic induction through enhancing caspase-3 activity (more than 2-fold) and arresting the cell cycle at the S phase ( P < .05). The obtained CAN1-encapsulated nanoliposomes suggest valuable applications in CSC-targeting treatment for more efficient clinical therapy.

Abstract
BACKGROUND Previous studies have observed lower utilization of maternal healthcare services by ethnic minority groups in Vietnam compared with the majority Kinh community. This study sought to assess the utilization of maternal healthcare service-associated factors within 12 ethnic minority groups. METHOD The cross-sectional study enrolled 996 women from 12 ethnic minority groups in Vietnam in 2019. Women had pregnancy outcomes in the last 5 years. The two variables for maternal healthcare utilization were [1] a minimum of four antenatal contacts and [2] health facility-based delivery. We examined the association of individual characteristics of maternal healthcare services using multilevel modeling. Odds ratios (ORs) and 95% confidence intervals (CIs) were reported. RESULTS This nationally representative study found that 34.1% of women from ethnic minority backgrounds had four or more antenatal contacts during pregnancy, ranging from 8.3% in Mong community to 80.2% in Cham An Giang. Most of the women (94.4%) delivered at health facilities. Factors independently correlated with having fewer than four antenatal contacts included being illiterate, early marriage, unemployment, religious affiliation, household economy, and distance to the nearest health facility. Factors significantly associated with home delivery were living in the most disadvantaged areas and having fewer than four antenatal contacts. CONCLUSION Substantial inequity exists in antenatal coverage both within ethnic minority groups and between socio-economic groups. The low coverage of having at least four antenatal contacts and its' correlates with facility-based delivery suggests that the government should focus efforts on increasing the number of antenatal contacts for ethnic minority women.

Abstract
BACKGROUND: The cerebral arterial aneurysm, especially in the circumstances of ateriovenous malformation (AVM), has higher risk of rupture than normal isolated aneursym. Therefore, the treatment strategy needs to be plan very carefully in such case. CASE PRESENTATION We report a patient with 2 wide-neck aneurysms located in the feeding artery of the arteriovenous malformation and he, then, was treated by using Surpass stent (flow-diverter) to eliminate the aneurysms. CONCLUSION: In our case, multiple wide-neck aneurysms in combination with low risk unruptured AVM, using long Surpass stent-diversion is an effective way to eliminate all the aneurysms in the main feeding artery while still preserving the AVM anatomy.

Abstract
Venous thromboembolism (VTE) is a frequent preventable complication among surgical patients. Precise risk assessment is a necessary step for providing appropriate thromboprophylaxis and reducing mortality as well as morbidity caused by VTE. We carried out this work to define the rate of VTE postoperatively, following a Caprini score, and to determine VTE risk factors through a modified Caprini risk scoring system. This multicenter, observational, cohort study involved 2,790,027 patients who underwent surgery in four Vietnamese hospitals from 01/2017 to 12/2018. All patients who were evaluated before surgery by using a Caprini risk assessment model (RAM) and monitored within 90 days after surgery. The endpoint of the study was ultrasound-confirmed VTE. Our data showed that the 90-day postoperative VTE was found in 3068 patients. Most of VTE (46.97%) cases were found in the highest risk group (Caprini score > 5). A total of 37.19% were observed in the high risk group, while the rest (15.84%) were from low to moderate risk groups. The likelihood of occurring VTE was heightened 2.83 times for patients with a Caprini score of 3–4, 4.83 times for a Caprini score of 5–6, 8.84 times for a score of 7–8, and 11.42 times for a score of >8, comparing to ones with a score of 0 to 2 (all p values < 0.05). Thus, the frequency of postoperative VTE rises substantially, according to the advanced Caprini score. Further categorizing patients among the highest risk group need delivering more appropriate thromboprophylaxis.

Abstract
Natural products play an important role in medicine and human healthcare and, as a result, drugs that are derived from natural resources are increasingly being used for the treatment of various diseases, including cancer. Vietlife-Antican (VLA) is a novel combination of curcumin solid lipid nanoparticles, ginger oleoresin solid lipid nanoparticles, and rutin solid lipid nanoparticles, which all possess low toxicity and enhanced bioavailabilities. To clarify the antitumor effects of this product, cytotoxic tests of VLA were conducted in various cancer cell lines in vitro and in an in vivo tumorized mouse model induced by Lewis lung carcinoma (LLC) cells. VLA expressed some cytotoxicity against breast cancer cells (MCF7), hepatocarcinoma cells (HepG2), lung cancer cells (SK-LU-1), colorectal adenocarcinoma cells (SW480), and human leukemia cells (HL-60). Additionally, LLC tumor-bearing mice treated with VLA (600 mg/kg body weight [bw]) exhibited significant reductions in tumor growth ( P < 0.05), a longer mean survival time (34.05 days), and improved liver function. Furthermore, a combination of VLA (200 mg/kg bw) and cisplatin strongly suppressed tumor development and increased mean survival time ( P < 0.05). Interestingly, cotreatment with VLA and cisplatin also induced the serum production of interleukin (IL)-2 and IL-10, which are important antitumor and anti-inflammatory cytokines, respectively, in tumorized mice. Taken together, the present results suggest that VLA may be a very promising and efficient phytochemical product that can support cancer treatment or therapy.

Abstract
A series of 4-anilinoquinazoline–triazole–AZT hybrids were designed and synthesized as anticancer agents. Their cytotoxic potential has been evaluated by means of a micro-dilution assay against three human cancer cell lines (KB, epidermoid carcinoma; HepG2, hepatoma carcinoma; SK-Lu-1, non-small lung cancer). The biological results revealed that compounds 4b and 6d showed good anticancer activities against KB, HepG2, and Lu cell lines (IC50 values ranging from 9 μM to 100 μM). Especially, compounds 4b and 6d exhibited up to 3-fold more potent than reference drugs erlotinib hydrochloride and AZT in term of anti-lung cancer activity.

Abstract
As a continuation of our interest in the anti-inflammatory activities of Vietnamese plants, we searched for novel anti-inflammatory agents in Eleutherine bulbosa and evaluated the anti-inflammatory effects of an ethanol extract of the rhizome of E. bulbosa (EBE) on lipopolysaccharide-stimulated RAW 264.7 macrophages in vitro and in a collagen antibody-induced arthritic (CAIA) mouse model in vivo. Treatment of the CAIA mice with EBE decreased the incidence of arthritis, especially at a dose of 1000 mg/kg body weight. A significant ( P<0.05) decrease in the arthritis score was seen after high-dose EBE treatment between days 10 and 14 in comparison with the negative control. The serum levels of the inflammatory cytokines tumor necrosis factor alpha (TNF-α), interleukin (IL)-6, and IL-10 in the mice were measured using commercial ELISA kits. The results suggest that an ethanol extract of the E. bulbosa rhizome has beneficial effects on inflammatory cytokine regulation in an experimental CAIA model.

Abstract
This study describes the chemical constituents of Oldenlandia pinifolia (Wall. Ex G. Don) Kuntze (synonym Hedyotis pinifolia Wall. Ex G. Don) and discusses their anti-proliferative activities. Thirteen compounds were isolated from the n-hexane, ethyl acetate and n-butanol extracts of whole plants O. pinifolia by chromatography method. Their structures were elucidated using MS and NMR analysis and compared with reported data. They are three anthraquinones, a carotenoid, two triterpenes, four iridoid glycosides and three flavonoid glycosides. Among them, 2-methyl-1,4,6-trihydroxy-anthraquinone is a new one, and three compounds were found for the first time in this genus. MTT assay resulted that the n-butanol extract and four isolated compounds inhibited the proliferation of chronic myelogenous leukaemia cells. The results from Hoechst 33343 staining and caspase 3-inducing exhibited that those four tested compounds induced apoptosis and activated caspase 3 (p < 0.05). One of them, isorhamnetin-3-O-β-rutinoside showed the most activity with IC50 value of 394.68 ± 25.12 μM.

Abstract
The anti-inflammatory compound, alphitonin-4-O-β-D-glucopyranoside (1), has previously been isolated in the leaves of Artokapus tonkinensis and synthesised from taxifolin. This study aimed to investigate the inhibitory effect of this compound on inflammatory cytokines, including tumour necrosis factor-alpha (TNF-α), interleukin (IL)-1, IL-6 and IL-10, in RAW264.7 macrophages and in an arthritis animal model. Compound 1 dose-dependently decreased the production of TNF-α, IL-1 and IL-6 in lipopolysaccharide-stimulated RAW264.7 cells. In contrast, the level of anti-inflammatory IL-10 increased. In a collagen antibody-induced arthritis BALB/c mouse model, compound 1 at a dose of 125 and 250 mg/kg body weight significantly decreased arthritis incidence in comparison with dexamethasone.

Abstract
OBJECTIVE To investigate the antitumor effect of maesopsin 4-O-β-glucoside (TAT2) isolated from the leaves of Artocarpus tonkinensis (A. tonkinensis) A. Chev. ex Gagnep. METHODS The antitumor activity of TAT2 was evaluated in Lewis lung carcinoma (LLC) tumor-bearing mice. BALB/c mice had tumors induced by implantation with 2 × 10(6) LLC cells into the subcutaneous right posterior flank. Tumor-bearing mice were treated orally with a range of doses of TAT2 and a standard drug, doxorubicin. Animals were observed for tumor growth and mortality rate. Blood was collected to determine hematological and biochemical parameters. RESULTS TAT2 was isolated from an ethanolic extract of A. tonkinensis leaves. Its structure was determined by MS and NMR spectroscopy, and identified as TAT2. The compound did not show acute toxicity at the highest dose tested (2000 mg/kg body weight). TAT2 exhibited antitumor activity by decreasing tumor growth, increasing the survival rate, and ameliorating some hematological and biochemical parameters at doses of 100 and 200 mg/kg body weight (P < 0.05). CONCLUSIONS These results indicate that TAT2 possesses clear antitumor activity. Due to its bioavailability and low toxicity, and the fact that it could be isolated in a large scale from A. tonkinensis leaves, the compound shows promise as a potential anticancer drug.

Abstract
Bioassay-guided fractionation led to the discovery of a novel neo-clerodane diterpenoid, scutebarbalactone VN (BalA: 8,13-epoxy-3-en-7-hydroxy-6,11-O- dibenzoyl-15,16-clerodanolide), from the methanol extract of the whole-plant of Vietnamese Scutellaria barbata D. Don. A microarray technique combined with bioinformatic analyses showed that BalA could inhibit cell cycle pathways by downregulating genes such as CDC25A and AURKA. BalA also showed the potential to reactivate downregulated genes in hepatocellular carcinoma cells and genes in antioxidant pathways such as HMOX1 and HSPA1A. Querying Connectivity map 2.0 resulted in a match of the BalA-modulated gene signature with that of 10 known compounds, most of which are currently marketed chemotherapy drugs. The highest matching scores belonged to lomustine, semustine, and withaferin A. Lomustine and semustine were found to alkylate DNA and RNA, while withaferin A inhibits nuclear factor kappa B (NF-κB) activity. A luciferase reporter assay was also conducted on 293/NF-κB human embryonic kidney cells that had been transfected with the NF-κB-luciferase plasmid to verify the anticancer activity of BalA. The assay showed that BalA effectively blocked NF-κB with an IC50 of 38.6 ± 0.05 μM.

Abstract
BACKGROUND If millions of neonatal deaths each year are to be prevented, one crucial component that must be improved is adequate care-seeking behaviour and effective use of existing health care systems. We have investigated these factors in relation to delivery and the neonatal period in a province in Northern Vietnam, a setting currently in socio-economic transition. METHODS Information on births and neonatal deaths between January and December 2005 in Quang Ninh province was collected. Narratives of the neonatal deaths were gathered and information about care-seeking in relation to delivery and illness was extracted. This information was then compared with the time and place of delivery and death. RESULTS We registered 17,519 births and 284 neonatal deaths occurring between January and December 2005. The neonatal mortality rate varied from 7.5/1000 to 38/1000, depending on the place of delivery. A quarter of the neonatal deaths had no contact with the health-care system at the time of death. Neonatal death within 24 hours of birth was more likely when the mother did not seek care at the time of delivery, or did so at the lowest level of the system (chi2=35.5, p<0.001). Mothers of ethnic minorities were more likely to exhibit this care-seeking behaviour at delivery. CONCLUSION Further improvement in neonatal survival can be achieved by changes in health system utilisation that aim to secure safe delivery for pregnant women. More efforts at local level are needed to encourage adequate care-seeking.

Abstract
A series of 65 intracranial tumours operated on, and followed by, the same surgical team during 7 years is presented as a retrospective analysis (1987-1994). Among these patients, only 38 had a diagnosis based upon computed tomography (CT) scan because it was not until 1991 that the first CT scanner was set up in Ho Chi Minh City. Many patients were drowsy or comatose prior to operation due to lack of specialists' intervention or tardy diagnosis and evacuation from remote provincial hospitals. All operations were satisfactory despite the lack of many essential instruments. The histological diagnosis followed the classification proposed by Zulch KJ.(1) Intratumoural calcification has in no case been seen on X-rays or on histological specimens. Operative mortality rate was nil. Although not all the patients with malignant tumours could be followed up, the data available concerning their survival time and the quality of life seems similar to that observed in other reports.

Abstract
Natural rubber from hevea brasiliensis trees (Thailand, RRIM 600 clone) of different age (8, 20, and 35 years) were characterized by size exclusion chromatography coupled with online viscometry according to their distribution of molar mass and branching index at a temperature of 70 degrees C using cyclohexane as solvent. Washing with an aqueous solution of sodium dodecylsulfate and subsequent saponification purified the natural rubber samples. With this procedure physical branching points caused by phospholipids, proteins and hydrophobic terminal units, mainly fatty acids, of the natural rubber (cis-1,4-polyisoprene) molecule, could be removed leading to completely soluble polymer samples. All samples investigated possess a very broad (10 to 50,000 kg/mol) and distinct bimodal molar mass distribution. With increasing age the peak area in the low molar mass region decreases favoring the peak area in the high molar mass region. By plotting the branching index as a function of the both, the molar mass and the age of the trees.

Abstract
This study analyzes the involvement of men in abortion in Vietnam, where induced abortion is legal and abortion rates are among the highest in the world. Twenty men were interviewed in 1996 about the role they played in their wives' abortions and about their feelings and ethical views concerning the procedure. The results showed that both husbands and wives considered the husband to be the main decisionmaker regarding family size, which included the decision to have an abortion, but that, in fact, some women had undergone an abortion without consulting their husbands in advance. Parents and in-laws were usually not consulted; the couples thought they might object to the decision on moral grounds. Respondents' ethical perspectives on abortion are discussed. When faced with an unwanted pregnancy, the husbands adopted an ethics of care and responsibility toward family and children, although some felt that abortion was immoral. The study highlights the importance of understanding husbands' perspectives on their responsibilities and rights in reproductive decisionmaking and their ethical and other concerns related to abortion.

Abstract
Although there is considerable interest among orthopaedic surgeons in the history of their specialty, many fail to pursue their interest because of an unfamiliarity with the tools and methods by which historical information can be assembled. The purpose of this article is to point out the resources for historical research available to most physicians and to give some suggestions for their use.

Abstract
2-Amino-X-benzothiazoles (X = H, 4-Cl, 6-Cl, 6-NO2, 6-CH3, 6-OCH3, 6-Br) react with N-phenylformamide and two equivalents of benzenesulfonyl chloride in pyridine, affording different products in dependence on the substituent X: N-(X-2-benzothiazolyl)formamidines, N-phenyl-N’-(X-2-benzothiazolyl)formamidines, N-phenyl-N’,N’’-bis(X-2-benzothiazolyl)triaminomethanes, N-(X-2-benzothiazolyl)benzenesulfonamides and N-2-((X-3-phenyliminomethyl)-benzothiazolylidene)benzenesulfonamides. In the presence of one equivalent of benzenesulfonyl chloride, benzothiazoles I either do not react or are partially benzenesulfonated.
