Genetic and environmental factors, such as metals, interact to determine neurological traits. We reasoned that interactomes of molecules handling metals in neurons should include novel metal homeostasis pathways. focused on copper its transporter ATP7A because null mutations cause neurodegeneration. performed immunoaffinity chromatography identified 541 proteins co-isolating with ATP7A. The interactome concentrated gene products implicated neurodegeneration neurodevelopmental disorders,...
The essential oils of five Lavandula stoechas cultivars grown in Thailand were characterized for their volatile compounds using GC-FID and GC/MS methods as well screened antibacterial antioxidant activities. Dried aerial parts, including flowers stems from each cultivar, subjected to hydrodistillation 4 h. oil yields 0.18 %-0.82 % w/w. Of the 95 detected identified, 1,8-cineole, fenchone, camphor considered major compounds. Essential cultivar demonstrated different patterns activity a...
Fungal endophytes are microorganisms living symbiotically with a host plant. They can produce volatile organic compounds (VOCs) that have antimicrobial activity. This study aimed to isolate endophytic fungi from Barleria prionitis plants grown in Thailand and investigate the antifungal properties of their VOCs against Colletotrichum acutatum , causal agent anthracnose disease on post-harvest strawberry fruits. A total 34 were isolated leaves B. . The produced each individual screened for...
Urban agriculture is emerging as a method to improve food security and public health in cities across the United States. However, an increased risk of exposure heavy metals metalloids (HMM) exists through interaction with contaminated soil. Community-engaged research (CEnR) one that can promote inclusion all partners when studying exposures such HMM Researchers community gardeners co-designed this study measure concentrations lead (Pb), using X-Ray Fluorescence (XRF) verified Inductively...
We conducted a cross-sectional study to assess the relationship between pesticide exposures and testosterone levels in 133 male Thai farmers. Urine serum samples were collected concurrently from participants. was analyzed for of specific nonspecific metabolites organophosphates (OPs), pyrethroids, select herbicides, fungicides. Serum total free testosterone. Linear regression analyses revealed significant negative relationships herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) after...
Two Fusarium fungi, F. oxysporum and proliferatum, have been recognized as major pathogenic fungi that cause postharvest decay of chili fruits. Ozone some toxic chemicals are used to control infections, leading longer storage lives agricultural commodities. However, these may pose risks the applicators environment. Therefore, alternative, easy-to-use fumigants for effective infections in harvested fresh chilies needed.Two endophytic Trichoderma afroharzianum strain MFLUCC19-0090 T....
Phytoremediation has been explored as a cost-effective method to remediate soil Pb contamination. A greenhouse study was conducted evaluate the efficacy of
We developed a robust analytical method for quantification of malondialdehyde (MDA) in urine and serum samples using dansylhydrazine (DH) as derivatizing reagent. The derivatization procedure was partially carried out an autosampler injection program to minimize errors associated with the low-volume addition reagents optimized yield stable hydrazone derivative MDA its labeled d2-MDA analogue. target MDA-DH derivatives were separated on Agilent Zorbax Eclipse Plus Phenyl-Hexyl (3.0 × 100 mm,...
This work aimed to characterise and compare the volatile profiles of Oolong tea No. 12 obtained from eight provenances in Chiang Rai province northern Thailand. Thirty-two samples were analysed using solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS). Sixty-seven constituents identified with their relative amounts. Principal Component Analysis (PCA) was used all revealed three major clusters. The main compounds responsible for differentiation linalool, geraniol,...
The Greater New York City area ranks highest in the United States number of nail salon technicians, primarily Asian immigrant women. Nail technicians are exposed to toxic phthalates and volatile organic compounds daily salons. purpose this pilot study was measure a mixture salons area, characterize work-related determinants indoor air quality these Working with four organizations we measured at 20 from February May 2021 using silicone wristbands passive samplers, respectively....
We developed and applied a method for measuring selected persistent organic pollutants (POPs) (i.e., polybrominated diphenyl ethers (PBDEs), organochlorine pesticides, polychlorinated biphenyls (PCBs)) in dust collected from pregnant African Americans (AAs) Atlanta using isotope dilution gas chromatography-tandem mass spectrometry. Limits of quantification were ranged 0.10 to 2.50 ng/g dust. NIST standard reference material measurements demonstrated the robustness our method. Our accuracies...
We developed and applied a method for measuring selected persistent organic pollutants (POPs) [i.e, polybrominated diphenyl ethers (PBDEs), organochlorine pesticides, polychlorinated biphenyls (PCBs)] in dust collected from pregnant African Americans (AAs) Atlanta. Our used liquid-liquid extraction followed by cleanup using Florisil solid phase car-tridge. analyzed the extracts gas chromatography-tandem mass spectrometry with electron impact ionization multiple reaction monitoring....
