heptanal

03/01/2014 - "The NvBN is able to selectively detect heptanal at a concentration as low as 1 × 10(-14) m, a sufficient level to distinguish the blood of a lung cancer patient from the blood of a healthy person. "
02/01/2010 - "heptanal maybe a useful marker in VOCs from patients with lung cancer."
02/01/2010 - "heptanal was detected in 45 patients of the lung cancer group, 1 of the benign lung disease group, and 1 of the healthy control group. "
08/29/2023 - "Determination of hexanal and heptanal in saliva samples by an adapted magnetic headspace adsorptive microextraction for diagnosis of lung cancer."
09/02/2020 - "Meanwhile, this method was successfully applied for the analysis of hexanal and heptanal in serum samples from healthy people and lung cancer patients. "

08/10/2007 - "This method was successfully applied to the analysis of hexanal and heptanal in plasma samples from different cancer patients."
09/02/2011 - "Results coming from the analysis of unknown biological samples showed no evident differences of heptanal urinary excretion between lung cancer patients and healthy subjects (0.22-0.95 and 0.21-0.69 pg μL(-1), respectively), while hexanal urinary concentrations in cancer patients (0.24-4.36 pg μL(-1)) were slightly higher than those found in control group ones (0.23-1.26 pg μL(-1)). "
01/01/1997 - "Aldehydes such as hexanal, heptanal, and malondialdehyde were strikingly higher in samples from cancer patients, while trans 4-cis-4-decenal was the prominent aldehyde in the blood of controls. "
06/01/2010 - "Acetaldehyde, propanal, butanal, heptanal and decanal concentrations showed no significant differences for cancer patients, smokers and healthy volunteers. "
09/15/2023 - "The result showed that the average total concentration of VOCs (17 μg/m3) was below the criterion for hygienic air, but seven substances, 2-ethylhexan-1-ol, benzene, isophorone, heptanal, naphthalene, benzyl chloride, and 1,2-dichloropropane exceeded the non-cancer health guidelines for lifetime exposure. "

01/01/2022 - "Detection of Covid-19 through a Heptanal Biomarker Using Transition Metal Doped Graphene."
10/01/2021 - "Three aldehydes (octanal, nonanal, and heptanal) drew special attention, as aldehydes are also elevated in the breath of adults with COVID-19. "
05/07/2021 - "Three aldehydes (octanal, nonanal, and heptanal) drew special attention, as aldehydes are also elevated in the breath of adults with COVID-19. "

07/15/2005 - "Finally, the proposed method was applied to the quantification of hexanal and heptanal in cancer blood and normal blood. "

01/01/2014 - "Three plant-based lures ((E)-linalool oxide [LO], (E)-linalool oxide and (E)-β-ocimene [LO + OC], and a six-component blend comprising (E)-linalool oxide, (E)-β-ocimene, hexanal, β-pinene, limonene, and (E)-β-farnesene [Blend C]), were tested alongside an animal/human-based synthetic lure (comprising heptanal, octanal, nonanal, and decanal [Blend F]) and worn socks in a malaria endemic zone in the western part of Kenya.
