Detection of microplastics in pterygium tissue: Implications for environmental hazards.

Purpose: This study aimed to report a case of microplastics (MPs) detection in a pterygium patient's tissue.

Case Report: A pterygium specimen was obtained from the right eye of a 43-year-old woman by surgical removal of a recurred pterygium. The number, morphology, and material type of the MPs in pterygium were identified using Raman microscopy and scanning electron microscopy.

Microplastic particles in human blood and their association with coagulation markers.

Recent studies have indicated potential health risks associated with microplastics (MPs) exposure, including alterations in blood coagulation homeostasis. This cross-sectional study aimed to quantitatively examine MPs in human blood and assess their association with coagulation markers. We recruited 36 healthy adults, collected whole blood samples, and analyzed MPs using Fourier-transform infrared (µ-FTIR) spectroscopy.

Microplastic contamination in artificial tears in South Korea: Potential for direct ocular exposure.

Purpose: To investigate microplastics (MP) contamination in artificial tear (AT) products.

Method: Five hyaluronic acid ATs (two multi-use and three disposable ATs) were used to gauge MP levels in three scenarios: 1) initial drop and remaining liquid after opening the lid upward; 2) remaining liquid after opening the lid downward and discarding two drops; and 3) remaining liquid after opening the lid downward and discarding half of it. Raman spectroscopy was used to identify the quantity, morphological characteristics, and composition of MPs.

Re-evaluation of risk and oncological outcomes of resection of veins and arteries in the resection of pancreatic cancer.

Background: Advances in chemotherapy have led to increasing major vascular resection during pancreatectomy which has been contraindicated due to high morbidity. This study aimed to verify the safety and oncological outcomes of vascular resection during pancreatectomy in the era of neoadjuvant therapy.

Methods: Data from patients who underwent surgery for pancreatic cancer at Seoul National University Hospital between 2001 and 2021 were reviewed.

Determination of Microplastics in Omega-3 Oil Supplements.

Microplastics (MPs) are ubiquitous in the environment, posing a threat to ecosystems and causing increasing concerns regarding their impacts on the human body through exposure. However, there has been limited research on the presence of MPs in functional foods, despite them being consumed for health improvement. This study aimed to investigate MP occurrence in various omega-3 oils and oil products in the Korean market and its relation to the source of raw material or manufacture.

Identification and characterization of microplastics in nasal irrigation fluids: A preliminary study.

Microplastics were identified in nasal irrigations Polypropylenes, which were the main component of the nozzle, were commonly identified Additional studies are needed to understand the biological relevance of microplastics in nasal irrigations.
