Low-Energy Collisions of Protonated Enantiopure Amino Acids with Chiral Target Gases.

K Kulyk et al.

Journal of the American Society for Mass Spectrometry, 28(12), 2686-2691 (2017-09-25)

Here we report on the gas-phase interactions between protonated enantiopure amino acids (L- and D-enantiomers of Met, Phe, and Trp) and chiral target gases [(R)- and (S)-2-butanol, and (S)-1-phenylethanol] in 0.1-10.0 eV low-energy collisions. Two major processes are seen to

Hematopoietic α7 nicotinic acetylcholine receptor deficiency increases inflammation and platelet activation status, but does not aggravate atherosclerosis.

S Kooijman et al.

Journal of thrombosis and haemostasis : JTH, 13(1), 126-135 (2014-10-28)

The autonomic nervous system attenuates inflammation through activation of the α7 nicotinic acetylcholine receptor (α7nAChR), a pathway termed the cholinergic anti-inflammatory reflex. Interestingly, α7nAChR is expressed on immune cells and platelets, both of which play a crucial role in the

CD36 is important for adipocyte recruitment and affects lipolysis.

Irene O C M Vroegrijk et al.

Obesity (Silver Spring, Md.), 21(10), 2037-2045 (2013-03-21)

The scavenger receptor CD36 facilitates the cellular uptake of long-chain fatty acids. As CD36-deficiency attenuates the development of high fat diet (HFD)-induced obesity, the role of CD36-deficiency in preadipocyte recruitment and adipocyte function was set out to characterize. Fat cell

The association between low birth weight and high levels of cholesterol is not due to an increased cholesterol synthesis or absorption: analysis in twins.

Richard G Ijzerman et al.

Pediatric research, 52(6), 868-872 (2002-11-20)

Low birth weight may be associated with high levels of cholesterol in later life through genetic factors that affect both birth weight and cholesterol metabolism. Alterations in cholesterol synthesis and absorption may play an important role in this association. We
