CuCoFe-LDO/BCD was successfully synthesized from CuCoFe-LDH and biochar derived from durian shell (BCD). Ciprofloxacin (CFX) degraded more than 95% mainly by O and O in CuCoFe-LDO/BCD(2/1)/PMS system within 10 min with a rate constant of 0.255 min, which was 14.

Methodology: A descriptive cross-sectional study was performed on people who have recovered from COVID-19 at least 2 weeks prior to the online survey.
Background: Hypertension is one of the leading causes of morbidity and mortality globally. It is a major risk factor for major cardiovascular events such as stroke, myocardial infarction, heart failure, kidney failure, and blindness. The aim of this research is to assess the prevalence and some factors related to arterial hypertension on Vietnamese seafarers aboard merchant vessels.

In this study, we present the chromosomal data of de novo AML patients in Southern Vietnam.
Methods: We performed cytogenetic testing for 336 AML patients using G banding.
Hipposideros larvatus sensu lato constitutes a widespread species complex consisting of morphologically similar forms with a taxonomy that is in need of a revision. Here we present the results of a phylogenetic analysis of members of this species complex based on two mitochondrial (CytB and COI) and seven nuclear (ABHD11, ACOX2, COPS, RAG2, ROGDI2, SORBS2 and THY) genes, and a morphometric analysis. Morphological data, although showing certain diversity, does not allow an accurate delimitation of the taxonomic boundaries and occasionally contradict to genetic grouping.

Here, we examined the potential for reducing VAP incidence through physical oral care interventions without any medication.
Methods: This prospective interventional study compared VAP incidence during an 8-month baseline period (usual oral care) and a 9-month intervention period (physical oral care with sponge brush) among patients who received mechanical ventilation for >48 h in a tertiary care hospital in Vietnam from 2017 to 2019.
Bats are the second-most speciose group of mammals, comprising 20% of species diversity today. Their global explosion, representing one of the greatest adaptive radiations in mammalian history, is largely attributed to their ability of laryngeal echolocation and powered flight, which enabled them to conquer the night sky, a vast and hitherto unoccupied ecological niche. While there is consensus that powered flight evolved only once in the lineage, whether laryngeal echolocation has a single origin in bats or evolved multiple times independently remains disputed.

Murid and cricetid rodents were previously believed to be the principal reservoir hosts of hantaviruses. Recently, however, multiple newfound hantaviruses have been discovered in shrews, moles, and bats, suggesting a complex evolutionary history. Little is known about the genetic diversity and geographic distribution of the prototype shrew-borne hantavirus, (TPMV), carried by the Asian house shrew (), which is widespread in Asia, Africa, and the Middle East.
View Article and Find Full Text PDFKnowledge as to the taxonomic status of enigmatic bat species often is hindered by limited availability of specimens. This is particularly true for aerial-hawking bats that are difficult to catch. One such species, "" , was originally described in due to its long and slender wings, but subsequently transferred to , and most recently to , on the basis of morphology.

View Article and Find Full Text PDFThe recent discovery of genetically distinct shrew- and mole-borne viruses belonging to the newly defined family Hantaviridae (order Bunyavirales) has spurred an extended search for hantaviruses in RNAlater®-preserved lung tissues from 215 bats (order Chiroptera) representing five families (Hipposideridae, Megadermatidae, Pteropodidae, Rhinolophidae and Vespertilionidae), collected in Vietnam during 2012 to 2014. A newly identified hantavirus, designated Đakrông virus (DKGV), was detected in one of two Stoliczka's Asian trident bats (Aselliscus stoliczkanus), from Đakrông Nature Reserve in Quảng Trị Province. Using maximum-likelihood and Bayesian methods, phylogenetic trees based on the full-length S, M and L segments showed that DKGV occupied a basal position with other mobatviruses, suggesting that primordial hantaviruses may have been hosted by ancestral bats.

It is also associated with a range of extreme morpho-physiological adaptations that evolved independently in three different vertebrate groups. Considering that development acts as a bridge between the genotype and phenotype on which selection acts, studying the ossification of the postcranium can potentially illuminate our understanding of bat flight evolution.
View Article and Find Full Text PDFThe discovery of highly divergent lineages of hantaviruses (family ) in shrews, moles, and bats of multiple species raises the possibility that non-rodent hosts may have played a significant role in their evolutionary history. To further investigate this prospect, total RNA was extracted from RNAlater-preserved lung tissues of 277 bats (representing five families, 14 genera and 40 species), captured in Myanmar and Vietnam during 2013⁻2016. Hantavirus RNA was detected in two of 15 black-bearded tomb bats () and two of 26 Pomona roundleaf bats () in Myanmar, and in three of six ashy leaf-nosed bats () in Vietnam.
View Article and Find Full Text PDFMost morphological and physiological adaptations associated with bat flight are concentrated in the postcranium, reflecting strong functional demands for flight performance. Despite an association between locomotory diversity and trophic differentiation, postcranial morphological diversity in bats remains largely unexplored. Evolutionary developmental biology is a novel approach providing a link between the analysis of genotypic and phenotypic variation resulting from selective pressures.

We investigated if reduction in the serum concentration of the cytokines tumor necrosis factor α, interleukin (IL)-6 and IL-10, and the rate of change in the IL-6 level at 24 h after ICU admission were survival predictors for patients with sepsis and septic shock in a Vietnamese population.

While numerous researchers have compared adult-stage morphology, few have studied the prenatal development of the cochlea. Here, we provide the first detailed three-dimensional description of the prenatal cranial development in bats, using Rhinolophus thomasi as a model, with particular interest to the petrosal which houses the cochlea.

Bone and muscular tendon morphometric data demonstrated that the Dong Tao breed was equipped with the extraordinarily thick and large tarsometatarsal bone and distal parts of the related tibiotarsus regions. Morphological differences between dorsal and plantar sides were clearly observed.

Hypsugo was regarded as a subgenus of Pipistrellus by many authors, but its generic distinctiveness is now widely accepted. According to recent taxonomic arrangements, nine species are known to occur in Southeast Asia. During the investigation of material recently collected from Lao PDR and Vietnam we identified an additional species and hence describe it here as Hypsugo dolichodon n.

The recently increased interest in studies on sequence heterochrony has uncovered developmental variation between species. However, how changes in developmental program are related to shifts in life-history parameters remains largely unsolved. Here we provide the most comprehensive data to date on postcranial ossification sequence of bats and compare them to various boreoeutherian mammals with different locomotive modes.
