Every year in the United States conifers are purchased to serve as Christmas trees in homes where they emit volatile organic compounds (VOCs) to the indoor environment. Although many studies have measured the ecosystem-level emissions of VOCs from conifers outdoors (characterizing monoterpene, isoprene, and aldehyde emissions), little is known about VOC emission rates once a conifer is brought indoors. Using a proton transfer reaction-mass spectrometer we characterized the VOCs emitted from a freshly cut Douglas Fir for 17 days in an environmentally controlled chamber.

The aim of this study was to determine the effect of silver nanoparticles (AgNPs) on donkey sperm parameters and ultrastructure. AgNPs were synthesized, purified and resuspended in the extender. Nine frozen-thawed donkey sperm samples were exposed to different concentrations of AgNPs (0, 1.

Absolute quantity imaging of biomolecules on a single cell level is critical for measurement assurance in biosciences and bioindustries. While infrared (IR) transmission microscopy is a powerful label-free imaging modality capable of chemical quantification, its applicability to hydrated biological samples remains challenging due to the strong IR absorption by water. Traditional IR imaging of hydrated cells relies on powerful light sources, such as synchrotrons, to mitigate the light absorption by water.

In Jamaica, stigma experiences of sex workers (SW), gay men and other men who have sex with men (MSM), and transgender women living with HIV remain understudied. To address this gap, we explored experiences of stigma and linkages with the HIV care cascade among key populations living with HIV in Jamaica, including cisgender women SW, MSM, and transgender women. This qualitative study involved n = 9 focus groups (FG), n = 1 FG per population living with HIV (SW, MSM, transgender women) in each of three sites (Kingston, St.
