Article Abstract

Mitochondrial respirometry provides a detailed assessment of oxygen consumption within the electron transport system, yet methods detailing respiration from non-invasive samples remain limited. Here, we present a protocol for measuring mitochondrial respiration in cultured buccal cells. We outline procedures for buccal cell collection, primary cell culture, and respirometry calibration, followed by oxygen consumption measurements and cell count for data normalization. This protocol allows reliable evaluation of mitochondrial function from non-invasive buccal cell samples, offering a valuable tool for metabolic investigation.

Epigenetic processes, such as DNA methylation, show potential as biological markers and mechanisms underlying gene-environment interplay in the prediction of mental health and other brain-based phenotypes. However, little is known about how peripheral epigenetic patterns relate to individual differences in the brain itself. An increasingly popular approach to address this is by combining epigenetic and neuroimaging data; yet, research in this area is almost entirely comprised of cross-sectional studies in adults.

Glyphosate-based herbicides are the most widely applied pesticides worldwide and have been implicated in the development of certain hematologic malignancies; however, the underlying biological mechanisms are not well-understood. High lifetime use of glyphosate-based herbicides, hereafter referred to as glyphosate, was previously associated with mosaic loss of chromosome Y (mLOY), a biomarker of genomic instability potentially linked to cancer and immune dysregulation, in circulating blood of male farmers from a subcohort of the Agricultural Health Study (AHS). Here, we further investigated the association between glyphosate use and mLOY using buccal-derived DNA among 1,868 male pesticide applicators in an independent AHS study.

Quantum dots (QDs) have diverse applications, ranging from optics and energy to biomedical. In this study, carbon quantum dots (CQDs) were synthesized using glucose and tryptophan as precursors using one-step microwave (MW) and sand bath (SB) thermal methods, and the CQDs exhibit distinct photoluminescence behaviors. CQD-SB shows enhanced and stable fluorescence despite its amorphous structure, likely due to prolonged thermal treatment, facilitating the formation of robust surface states and stable reaction products.

BACKGROUND Down syndrome, or trisomy 21, is one of the most common chromosomal disorders associated with intellectual disability. Prenatal screening is a proactive approach to identify fetuses with common chromosomal abnormalities. Mosaicism is one of the causes of false-negative results in prenatal screening for Down syndrome.

Occupational exposure to air pollutants poses a serious health concern for workers, particularly due to potential genotoxic effects. The micronucleus (MN) test is widely recognized as a reliable biomarker of early genetic damage. Although commonly applied to lymphocytes or buccal epithelial cells, the nasal mucosa, being the first site of contact for inhaled toxicants, has received relatively limited attention.
