The pitviper species Trimeresurus caudornatus was recently described based on only two specimens from Nabang Town, Yingjiang County, Yunnan Province, China. Here, we provide additional data on this species based on a re-examination of 19 preserved specimens, 16 specimens reported in earlier literature sources, and additional photo-documented records from northern Myanmar (Burma) and adjacent China. All new specimens were previously identified as Trimeresurus albolabris sensu lato or Trimeresurus septentrionalis sensu lato.

  • The Malayan banded wolf snake (Lycodon subcinctus) has an intricate taxonomic history, with confusion surrounding its classification, particularly regarding the name Anoplophallus maculatus.
  • Recent studies proposed raising a Chinese population of L. subcinctus to a species level, leading researchers to clarify that Anoplophallus maculatus actually refers to a different Neotropical snake.
  • As a resolution, a new species name, Lycodon neomaculatus sp. nov., has been proposed for Chinese populations and is characterized by distinct color patterns and scalation, with its distribution being separate from L. subcinctus.

Background: Contrast-induced nephropathy is a prevalent cause of hospital-acquired renal insufficiency and increases adverse events in older patients undergoing angiography and percutaneous coronary intervention. The Mehran risk score has been widely used in Vietnam to assess contrast-induced nephropathy risk in patients before coronary angiography and percutaneous coronary intervention. Recently, there has been a shift toward the adoption of simpler risk prediction models, such as the contrast volume-to-glomerular filtration rate ratio.

  • Miniature random lasers are important for fields like barcoding, bioimaging, and on-chip technologies, but creating size-tunable, biocompatible versions has been difficult.
  • This study used poly(lactic-co-glycolic) acid (PLGA), a medical-approved material, to create monodisperse dye-doped PLGA spheres with controllable sizes from 25 to 52 µm.
  • The spheres showed strong lasing emissions at wavelengths of 610-640 nm and a high quality factor of 3100, with detailed analysis providing insights into their structure.

  • Xuan Lien Nature Reserve in Vietnam, established in 1999, aims to protect wildlife and habitats but faces serious human disturbances, prompting a need for updated species data.
  • In 2023, a systematic camera trapping survey was conducted across 21,000 hectares, documenting at least 46 species from 39 genera, with a focus on mid- to large-sized terrestrial vertebrates.
  • The study highlights Xuan Lien as vital for small carnivores, yet revealed concerning results regarding overhunting threats, particularly affecting species like ungulates.

Enhancement of the ionic conductivity and reduction of diffusion barriers of lithium-ion batteries are crucial for improving the performance of the fast-growing energy storage devices. Recently, the fast-charging capability of commercial-like lithium-ion anodes with the smallest modification of the current manufacturing technology has been of great interest. We used first principles methods computations with density functional theory and the climbing image-nudged elastic band method to evaluate the impact of an external electric field on the stability, electronic band gap, ionic conductivity, and lithium-ion diffusion coefficient of penta-graphene nanoribbons upon lithium adsorption.

With 90 recognized species, kukri snakes in the genus Oligodon Fitzinger constitute the second largest snake radiation in the world. Oligodon species are collectively distributed across the Asian continent and possess several ecological and morphological attributes that are unique amongst other snakes. Despite their high levels of species richness, evolutionary relationships within Oligodon are poorly understood due to a limited number of samples and genetic markers available in earlier phylogenies.

Introduction: This study aimed to describe the epidemiology and etiologies of critical respiratory diseases of ex-premature infants (EPIs) admitted to the Pediatric Intensive Care unit (PICU).

Methods: Infants ≤2 years old with acute respiratory illnesses admitted to PICU of Vietnam National Children's Hospital from November 2019 to April 2021 were enrolled and followed up to hospital discharge. We compared respiratory pathogens, outcomes, and PICU resources utilized between EPIs and term infants.

  • The study focuses on the marine red alga known for its economic importance in agar production and medicinal compounds, presenting its complete mitochondrial genome (mitogenome) for the first time.
  • The mitogenome is a circular structure with 25,909 base pairs, containing 24 protein-coding genes, 2 ribosomal RNA genes, 24 transfer RNA genes, and an open reading frame of unknown function, demonstrating highly conserved gene structures.
  • Phylogenetic analysis indicates that this alga is closely related to other species in its family, and this research will aid in future studies on the evolutionary relationships of marine red algae.

Extranodal natural killer (NK)/T-cell lymphoma, nasal type is a rare, aggressive, and poor prognostic subtype. The concurrent chemoradiotherapy followed by chemotherapy showed a relatively high response rate and the toxicity due to the treatment is acceptable. The study attempted to report the clinicopathological features, the survival outcome, and response rates of stages I-II, nasal type ENKTL patients treated with CCRT followed by adjuvant VIPD chemotherapy in Vietnam.

Introduction: Older patients typically face elevated mortality rates and greater medical resource utilization during hospitalizations compared to their younger counterparts. Sarcopenia, serving as a prognostic indicator, is related to disability, diminished quality of life, and increased mortality. The SARC-F questionnaire, known for its cost-effectiveness, offers a valuable means of assessing sarcopenia.
