The Impact of Root Temperature on Photosynthesis and Isoprene Emission in Three Different Plant Species by Mauro Medori, Lucia Michelini, Isabel Nogues, Francesco Loreto, Carlo Calfapietra

“…Our findings suggest that the increase of isoprene could be a good marker of heat stress, whereas the decrease of isoprene a good marker of accelerated foliar senescence, two hypotheses that should be better investigated in the future.…”

Study of the neuronal response to olfactory stimuli in control and LPS-stimulated mice by functional magnetic resonance imaging by A. E. Akulov, A. V. Romashchenko, O. B. Shevelev, D. V. Petrovski, A. A. Savelov, M. P. Moshkin

“…This work considers use of fMRI in the study of the influence of innate immunity activation on neuronal response during perception and differentiation of socially significant (2.5-dimethylpyrazine, 2-heptanon) and socially insignificant (1-hexanol and isoprene) olfactory stimuli by CD-1 mice. We stimulated innate immunity by intraperitoneal injection of bacterial lipopolysaccharide (LPS) at the dose 500 µg/kg three hours before tomography. …”

Spatial-temporal Characteristics and Source Apportionment of Ambient VOCs in Southeast Mountain Area of China by Xiaoting Ji, Ke Xu, Dan Liao, Gaojie Chen, Taotao Liu, Youwei Hong, Sijun Dong, Sung-Deuk Choi, Jinsheng Chen

“…Based on the OH radical loss rate (LOH) and ozone formation potential (OFP) analysis, alkenes had the highest chemical activity, especially the contribution of isoprene in rural areas. Aromatics contributed the most to secondary organic aerosols (SOA) formation in both county and rural areas. …”

Global decadal measurements of methanol, ethene, ethyne, and HCN from the Cross-track Infrared Sounder by K. C. Wells, D. B. Millet, J. F. Brewer, V. H. Payne, K. E. Cady-Pereira, R. Pernak, S. Kulawik, S. Kulawik, C. Vigouroux, N. Jones, E. Mahieu, M. Makarova, T. Nagahama, I. Ortega, M. Palm, K. Strong, M. Schneider, D. Smale, R. Sussmann, M. Zhou

“…We update the Retrieval of Organics from CrIS Radiances (ROCR) algorithm developed previously for isoprene to explicitly account for the spectral signal dependence on the VOC vertical profile shape, and we apply this updated retrieval (ROCRv2) to derive column abundances for the targeted species across the full Suomi NPP CrIS record (2012–2023). …”

Correlation between follicle diameter and pre-ovulatory metabolic profile in Bos grunniens by Jiuru Yan, Jiuru Yan, Jiuru Yan, Yuxin Fu, Yuxin Fu, Yuxin Fu, Lan Lan, Huizhu Zhang, Huizhu Zhang, Huizhu Zhang, Ling Huang, Ling Huang, Yaying Wang, Yaying Wang, Xianrong Xiong, Xianrong Xiong, Xianrong Xiong, Shi Yin, Shi Yin, Shi Yin, Jian Li, Jian Li, Jian Li, Honghong He, Honghong He, Honghong He

“…Differential metabolites enriched KEGG pathways to screen the pathways that might be related to follicle development.ResultsWe found that most of the metabolites were mainly enriched in amino acid metabolism pathways, energy metabolism pathways and other pathways of cofactor synthesis, and that during the development of the small follicle to the large follicle, 2-Lysophosphatidylcholine, PC (17:0/0:0), PC (16:0/0:0), and LysoPC (18:0/0:0) were down-regulated; Dioctyl succinate, P-Coumaraldehyde, ISOPRENE, L-Isoleucine, Dioctyl succinate up-regulated.ConclusionThese results suggest that amino acid metabolism, the production of steroid hormones and their metabolites, and the metabolic activity of granulosa cells play important roles in follicle development. …”
