Paleoneurology reconstructs the evolutionary history of nervous systems through direct observations from the fossil record and comparative data from extant species. Although this approach can provide direct evidence of phylogenetic links among species, it is constrained by the availability and quality of data that can be gleaned from the fossil record. Here, we sought to translate brain component relationships in a sample of extant Carnivora to make inferences about brain structure in fossil species.

Article Synopsis
  • Tropical estuaries, like the one in Ho Chi Minh City, are facing serious ecological threats due to urbanization and the introduction of numerous micropollutants into their waters.
  • The research assessed water quality along a 140-km stretch of the Saigon River and its estuary, identifying 120 micropollutants, with many showing high detection frequencies and varying concentrations.
  • Key sources of contamination were found to be urban canals, particularly one canal that surpassed safety thresholds for estrogenic effects, highlighting the urgent need for better pollution management strategies in the region.

Article Synopsis
  • The study assessed the reliability and validity of the Vietnamese version of the eHealth Literacy Scale (eHEALS) among medical students at Hanoi Medical University, highlighting the significance of eHealth literacy during the COVID-19 pandemic.
  • A total of 494 medical students participated, and results indicated a good eHEALS score of 30.34 ± 4.57, with high reliability demonstrated through various statistical tests.
  • Key factors influencing eHEALS scores included the students' device usage, ongoing medical conditions, and the trustworthiness of health information sources, suggesting areas for further research in eHealth literacy.

Epiploic appendagitis is a rare and commonly misdiagnosed cause of acute abdominal pain. Treatment for the initial presentation of epiploic appendagitis is conservative management with anti-inflammatory medications. There is no consensual treatment algorithm for recurrent appendagitis as some studies recommend conservative management and others recommend surgical excision.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzyme disorder and is caused by G6PD gene mutations. To date, more than 400 variants in the G6PD gene have been discovered, and about 160 identified variants are associated with a significant decrease in the G6PD enzyme activity. However, the molecular characterization and epidemiological study of G6PD deficiency are still limited in Vietnam.

Developing regions experience rapid population growth and urbanisation, which require large quantities of materials for civil infrastructure. The production of construction materials, especially for urban transport systems, however, contributes to local and global environmental change. Political agendas may overlook the environmental implications of urban expansion, as economic growth tends to be prioritised.

There is growing worry that drinking water can be affected by contaminants of emerging concern (CECs), potentially threatening human health. In this study, a wide range of CECs (n = 177), including pharmaceuticals, pesticides, perfluoroalkyl substances (PFASs) and other compounds, were analysed in raw water and in drinking water collected from drinking water treatment plants (DWTPs) in Europe and Asia (n = 13). The impact of human activities was reflected in large numbers of compounds detected (n = 115) and high variation in concentrations in the raw water (range 15-7995 ng L for ∑CECs).

Partial discharge (PD) is a major indicator of various failures in power grid systems. PD exhibits a physical occurrence where a localized electrical discharge happens in insulation materials. This phenomenon causes damage to the insulating parts and, in various circumstances, leads to complete insulation breakdown.

Sedimentological and geochemical data were obtained for bed sediments from a tropical estuary environment in Vietnam in October 2014, January 2016, and November 2016. The data include grain-size distribution, percentage of clay, silt and sand, percentage of organic matter, concentration of total particulate phosphorus (TPP), concentration of particulate inorganic phosphorus (PIP), concentration of particulate organic phosphorus (POP), percentage of total nitrogen (TN), percentage of total carbon (TC), trace metals concentrations (V, Cr, Co, Ni, Cu, Zn, As, Mo, Cd, Pb) and major elements (Al, Fe, Mn). Geochemical indexes (Enrichment factor EF and Geo-accumulation Index I-geo) and sediment quality guideline (mean Effect Range Median quotients) were calculated.

This study investigated the growth dynamics of a freshwater and marine microalgae with supported biochemical performance in saline wastewater, the pollutants assimilation by a developed method, and the mechanism of salinity's effect to pollutants assimilation. Maximal biomass yield was 400-500 mg/L at 0.1-1% salinity while the TOC, NO-N, PO-P were eliminated 39.

Article Synopsis
  • The Mekong Delta, with 17 million residents, faces climate change and environmental challenges, prompting a study on trace metal concentrations in the Tien River across different seasons.
  • The research found that despite low concentrations of metals like Al, V, and Pb in water and sediments, V, Cr, Co, As, and Pb were primarily found in particulate phases, while Mo, Ni, and Cu were more dissolved.
  • An examination of sediments revealed that particle size and certain oxides controlled metal concentrations; however, arsenic showed enrichment and there were varying levels of ecotoxicological potential in surface sediments.

This study aimed to evaluate the performance of a high rate nitrogen removal lab-scale ANAMMOX reactor, namely Internal Circulation (IC) reactor, for old landfill leachate treatment. The reactor was operated with pre-treated leachate from a pilot Partial Nitritation Reactor (PNR) using a high nitrogen loading rate ranging from 2 to 10kgNmd. High rate removal of nitrogen (9.

The Saigon River, Southern Vietnam, crosses one of the most dynamic developing Megacity in Southeast Asia: Ho Chi Minh City (HCMC). The increased economic, industrial, and domestic developments may affect the environmental quality of water and halieutic resources. In this study, we evaluated the seasonal (dry and wet seasons) biogeochemical state of the Saigon River during two snapshot campaigns conducted along the river basin upstream from HCMC; the Saigon River was characterized by slightly acidic (pH 5.

This work attends to preparation and characterization of a novel multi-metal binding biosorbent after chemical modification and desorption studies. Biomass is a combination of tea waste, maple leaves and mandarin peels with a certain proportion to adsorb cadmium, copper, lead and zinc ions from aqueous solutions. The mechanism involved in metal removal was investigated by SEM, SEM/EDS and FTIR.

To tackle current water insecurity concerns, wastewater reclamation and reuse have appeared as a promising candidate to conserve the valuable fresh water sources while increasing the efficiency of material utilization. Climate change, nevertheless, poses both opportunities and threats to the wastewater reclamation industry. Whereas it elevates the social perception on water-related issues and fosters an emerging water-reuse market, climate change simultaneously presents adverse impacts on the water reclamation scheme, either directly or indirectly.

The vacuolar-type H+ -ATPase (V-ATPase) is a multimeric enzyme with diverse functions in plants such as nutrient transport, flowering, stress tolerance, guard cell movement and development. A partial sequence of V-ATPase proteolipid was identified among the expressed sequence tags (ESTs) generated from Acanthus ebracteatus, and selected for full-length sequencing. The 876-nucleotide cDNA consists of an open reading frame of 165 amino acids.

One hundred and one pummelo plants representing eight different cultivars of pummelo were fingerprinted and evaluated for intra- and inter-varietal variability using five enzyme systems. Starch gel electrophoresis was used to analyse extracts from fresh young leaves collected from trees located in the provinces of Can Tho and Vinh Long. Isozymic analysis revealed that all cultivars are isozymically heterogeneous, and composed of two or more clones.
