Mar Pollut Bull

December 2024

Aix Marseille University, Université de Toulon, CNRS, IRD, MIO UM110, 13288 Marseille, France; Department Water-Environment-Oceanography, University of Science and Technology of Hanoi (USTH), Vietnamese Academy of Science and Technology (VAST), 18 Hoang Quoc Viet, Hanoi 100000, Viet Nam; IRD, Chulalongkorn University, 254 Henri Dunant Road, Pathumwan, 10330 Bangkok, Thailand.

Article Synopsis
  • Halong Bay in northern Vietnam is experiencing significant environmental impact from human activities, specifically from metals and metalloids used as indicators for tracing anthropogenic contributions.
  • Two sediment cores, one from coastal waters and another from a small isolated lake, revealed that the coastal site (HL) had a much higher accumulation rate than the lake site (HT).
  • Key findings indicate that the coastal waters are heavily influenced by the Red River drainage, with particular historical pollution spikes linked to significant events like the Indochina War and various regional flooding incidents.

Plasma nitriding is one of the surface modifications that show more effectiveness than other methods. In this study, the plasma-based ion implantation (PBII) technique was performed on the surface of titanium alloy (Ti-6Al-4V, Ti64) using a mixture of nitrogen (N) and argon (Ar), resulting in a plasma-nitrided surface (TiN-Ti64). The surface composition of the TiN-Ti64 was verified through X-ray photoelectron spectroscopy (XPS).

Cholangiocarcinoma (CCA) is a bile duct malignancy. Our previous comprehensive analysis showed that ferroptosis-related genes can stratify CCA patients into low-risk and high-risk groups based on survival time. Here, we explored the role of ferroptosis in CCA by analyzing mRNA expression in CCA patients from public databases.

Background: Optimising management of second-trimester medical abortion is important, as complications increase with gestational age. We aimed to compare a 24-h interval with a 48-h interval between mifepristone intake and misoprostol administration in in-hospital, second-trimester medical abortion for effectiveness and acceptability.

Methods: This open-label, randomised, controlled, non-inferiority trial was conducted at nine hospitals in India, Sweden, Thailand, and Viet Nam among adults undergoing medical abortion for a singleton viable pregnancy at a gestation of between 9 weeks and 20 weeks.

Introduction: Chronic shoulder pain caused by a rotator cuff tear is commonly treated with arthroscopic rotator cuff repair surgery (ARCR). However, ARCR may be associated with moderate-to-severe postoperative pain, and poorly controlled pain can result in delayed functional recovery and the development of frozen shoulder. Terminal sensory articular nerve radiofrequency ablation (RFA) has been shown to be clinically effective in patients with severe refractory shoulder pain from multiple etiologies.

Article Synopsis
  • Delivering dsRNA to shrimp is difficult due to ineffective carrier systems, but this study optimized chitosan nanoparticles (CNs) from shrimp and squid for better encapsulation.
  • Both CN types showed high encapsulation efficiency and stability, with shrimp-derived CNs providing better protection against RNase and more controlled release compared to squid-derived CNs.
  • Ultimately, shrimp-derived CNs were more effective in protecting dsRNA and reducing mortality from white spot syndrome virus (WSSV), making them a promising solution for shrimp aquaculture.

December 2024

Center of Excellence in Genomics and Precision Dentistry, Department of Physiology, Faculty of Dentistry, Chulalongkorn University, Bangkok, Thailand.

Fungi present in Dental Unit Water (DUW) can pose a health hazard to patients and dental personnel. Yet, the issue of fungal contamination of DUW and their conduits, DUW Lines (DUWLs) has been poorly addressed despite a growing body of data on the subject. In this comprehensive review, we aim to address this gap by examining the diverse fungal contaminants found in DUW, the challenges associated with controlling their growth within waterline biofilms, and the various measures employed for fungal decontamination.

Center of Excellence in Phytochemical and Functional Food for Clinical Nutrition, Department of Nutrition and Dietetics, Faculty of Allied Health Sciences, Chulalongkorn University, Bangkok 10330, Thailand.

Pomelo juice, especially from the Tubtim Siam cultivar, may offer prebiotic benefits by promoting beneficial gut bacteria. This study evaluated the impact of non-fermented and ()-fermented pomelo juice on gut microbiota using an colonic fermentation model. The -fermented juice significantly increased lactobacilli levels compared to the non-fermented juice, while both treatments similarly suppressed coliforms within 24 h Microbiota analysis revealed increased richness and significant community shifts in both treatments.
