In-House Immunoglobulin Y-Based Immunoassay for Detecting Benzo[a]pyrene in Grilled Pork Samples.

Benzo[a]pyrene (B[a]P) is a hazardous polycyclic aromatic hydrocarbon that accumulates in several environmental matrices as a result of incomplete combustion. Its presence, carcinogenic properties, and tendency for bioaccumulation provide significant risks to human health and the environment. The objective of this study is to create an immunoassay for the detection of benzo[a]pyrene utilizing immunoglobulin Y antibodies.

Impact of fine particulate matter (PM) on ocular health among people living in Chiang Mai, Thailand.

Considering the limited information on the impact of PM content on ocular health, a follow-up study was conducted on 50 healthy adults. Samples were collected twice, once before the PM exposure season and again after exposure. Daily PM concentration data was gathered from Thung Satok monitoring station.

Antioxidant Capacity, Phytochemicals, Minerals, and Chemical Pollutants in Worker Honey Bee ( L.) Broods from Northern Thailand: A Safe and Sustainable Food Source.

Honey bee brood (HBB) ( L.), a traditional protein source, has been studied for its nutritional value, but bio-functional properties and safety concerns have not been verified. This study examined the Antioxidant capacity, phytochemicals, minerals, and chemical pollutants in worker broods from several apiaries in Northern Thailand.

Isolation and Identification of Microorganisms and Antibiotic Resistance Microorganisms from Beehives Located in Palm, Corn and Longan Plantations, Thailand.

This study aims to determine the prevalence of microorganisms and antibiotic-resistant microorganisms in beehives located on different plantations in Thailand. Seventeen swabs immersed in transport media were utilized for samples from different zones within beehives. Traditional microbial culture-based methods, biochemical tests, MALDI-TOF MS (VITEK MS, bioMerieux, Marcy-l'Étoile, France), and antibiotic drug susceptibility (disk-diffusion) tests were used to detect microorganism and antimicrobial resistance bacteria.

Phytochemical Profiling and Antioxidant Capacity of Traditional Plants, Northern Thailand.

Traditional plants have played a significant role in human culture and medicine throughout history. These plants have the capability to synthesize a diverse range of chemical compounds that serve essential biological functions. This study's objective was to analyze the phytochemical composition of five traditional plants, namely , , , , and , native to northern Thailand, using LC-QTOF/MS analysis and assess their potential bioactivity through various assays including DPPH radical scavenging activity, ABTS radical scavenging activity, ferric ion reducing antioxidant power, total phenolic compounds, and total flavonoid content.

Dopamine as a polymerizable reagent for enzyme-linked immunosorbent assay using horseradish peroxidase.

We demonstrate that dopamine can be used as a reagent for colorimetric enzyme-linked immunosorbent assay (ELISA) using horseradish peroxidase (HRP). Dopamine was able to be polymerized in the presence of HRP and HO, and black polydopamine was obtained after the enzymatic reaction. Because of the black color, the absorbance was significantly changed in the whole range of the visible light region.

Antioxidant and Phytochemical Potential of and Phytochemicals in (Lour.) Decne in Northern Thailand.

(Lour.) Decne is a vegetable local to Chiang Mai Province of Northern Thailand. This study aimed to analyze the antioxidant and phytochemical potential of found in Chiang Mai Province; antioxidant compounds of were tested via DPPH, ABTS and FRAP assays, and total phenolic compound and total flavonoid contents were analyzed.

Development of IgY-Based Indirect Competitive ELISA for the Detection of Fluoroquinolone Residues in Chicken and Pork Samples.

Fluoroquinolones (FQs) are among the antibiotics whose widespread use in farm-raised animals results in potentially harmful residues in the end products. Additionally, most Thai farmers use antibiotics. Amoxicillin and enrofloxacin were commonly used by pig farms, and hens were given enrofloxacin to prevent immunization side effects.

Tentative Identification of Phytochemicals from and Extracts by LC-QTOF/MS and Their Bioactive Potential.

The Smilacaceae family has been used as a food source and herbal medicine for a long time. This study aims to identify the phytochemicals extracted from and by using LC-QTOF/MS analysis and determine their bioactive potential. Compounds were identified from and extracts by LC-QTOF-MS and it was found that longistylin A and CAY10435 have higher degrees of matching compounds (99.
