Cardiac-targeted NADPH oxidase 4 in the adaptive cardiac remodelling of the murine heart.

Lancet (London, England)

Nabeebaccus A, Hafstad A, Eykyn T, Yin X, Brewer A, Zhang M, Mayr M, Shah A.
PMID: 26312895
Lancet. 2015 Feb 26;385:S73. doi: 10.1016/S0140-6736(15)60388-9.

BACKGROUND: The mechanisms that determine whether the heart adapts to overload stress, or fails, are poorly understood. NADPH oxidase (NOX) proteins produce reactive oxygen species (ROS) involved in redox signalling, and our recent studies have found that an increase...

Mitochondrial 3-Hydroxy-3-Methylglutaryl-CoA Synthase Deficiency: Unique Presenting Laboratory Values and a Review of Biochemical and Clinical Features.

We report an 8-month-old infant with decreased consciousness after a febrile episode and reduced oral intake. He was profoundly acidotic but his lactate was normal. Serum triglycerides were markedly elevated and HDL cholesterol was very low. The urine organic...

Mutation analysis of methylmalonyl CoA mutase gene exon 2 in Egyptian families: Identification of 25 novel allelic variants.

Meta gene

Ghoraba DA, Mohammed MM, Zaki OK.
PMID: 25750861
Meta Gene. 2015 Feb 25;3:71-88. doi: 10.1016/j.mgene.2014.02.001. eCollection 2015 Feb.

Methylmalonic aciduria (MMA) is an autosomal recessive disorder of methylmalonate and cobalamin (cbl; vitamin B12) metabolism. It is an inborn error of organic acid metabolism which commonly results from a defect in the gene encoding the methylmalonyl-CoA mutase (MCM)...

Cholinesterase-catalyzed resolution of D,L-carnitine.

Biotechnology and bioengineering

Dropsy EP, Klibanov AM.
PMID: 18553477
Biotechnol Bioeng. 1984 Aug;26(8):911-5. doi: 10.1002/bit.260260815.

An enzymatic method for the preparative resolution of racemic carnitine (whose L-isomer and its acyl-derivatives have numerous therapeutical applications) has been developed. It is based on our finding that electriceel acetylcholinesterase hydrolyzes the D- but not the L-isomer of...

Mediation of phorbol ester-induced oxidant generation in murine epidermal cells by protein kinase C.

Toxicology in vitro : an international journal published in association with BIBRA

Fischer SM, Baldwin JK, Jasheway DW, Patrick KE.
PMID: 20837424
Toxicol In Vitro. 1989;3(3):195-9. doi: 10.1016/0887-2333(89)90005-2.

Murine epidermal cells have previously been shown to produce an oxidant response to the mouse skin tumour promoter 12-O-tetradecanoylphorbol-13-acetate (TPA); however, the cellular source of these oxidants has not been well characterized. The demonstration that phospholipase C also elicits...

Early metabolic response to acute myocardial ischaemia in patients undergoing elective coronary angioplasty.

Open heart

Di Marino S, Viceconte N, Lembo A, Summa V, Tanzilli G, Raparelli V, Truscelli G, Mangieri E, Gaudio C, Cicero DO.
PMID: 29632675
Open Heart. 2018 Mar 10;5(1):e000709. doi: 10.1136/openhrt-2017-000709. eCollection 2018.

OBJECTIVE: Balloon-induced transient coronary ischaemia represents a model of myocardial ischaemia and reperfusion. We are interested in the very early systemic metabolic response to this event.METHODS: Blood samples of patients with stable angina (SA) were collected before and after...

Serum metabolomics analysis reveals increased lipid catabolism in mildly hyperbilirubinemic Gilbert's syndrome individuals.

Metabolism: clinical and experimental

Hana CA, Tran LV, Mölzer C, Müllner E, Hörmann-Wallner M, Franzke B, Tosevska A, Zöhrer PA, Doberer D, Marculescu R, Bulmer AC, Freisling H, Moazzami AA, Wagner KH.
PMID: 34653509
Metabolism. 2021 Dec;125:154913. doi: 10.1016/j.metabol.2021.154913. Epub 2021 Oct 20.

BACKGROUND: The protective role of mildly elevated bilirubin against CVD and diabetes mellitus type 2 (DMT2) is associated with a favorable lipid phenotype. As the mechanistic understanding of this protection in humans remains elusive, we aimed to assess the...

Nuclear magnetic resonance spectroscopy to investigate the association between milk metabolites and udder quarter health status in dairy cows.

Journal of dairy science

Bobbo T, Meoni G, Niero G, Tenori L, Luchinat C, Cassandro M, Penasa M.
PMID: 34656344
J Dairy Sci. 2021 Oct 13; doi: 10.3168/jds.2021-20906. Epub 2021 Oct 13.

Nuclear magnetic resonance spectroscopy was applied to investigate the association between milk metabolome and udder quarter health status in dairy cows. Mammary gland health status was defined by combining information provided by traditional somatic cell count (SCC) and differential...

Age and sex dependent changes of free circulating blood metabolite and lipid abundances, correlations and ratios.

The journals of gerontology. Series A, Biological sciences and medical sciences

Di Cesare F, Luchinat C, Tenori L, Saccenti E.
PMID: 34748631
J Gerontol A Biol Sci Med Sci. 2021 Nov 08; doi: 10.1093/gerona/glab335. Epub 2021 Nov 08.

In this study we investigated how the concentrations, pairwise correlations, and ratios of 202 free circulating blood metabolites and lipids vary with age in a panel of n=1882 subjects ranging from 48 to 94 years. We report a statistically...

A dramatic conformational effect of multifunctional zwitterions on zeolite crystallization.

Chemical communications (Cambridge, England)

Carnitine functions as a mesoporogen in LTA zeolite synthesis whereas its structural analogue acetylcarnitine acts as a crystal growth modifier. An array of experimental and theoretical studies reveal a remarkable effect of molecular conformation on the actual roles of...

A Multivariate Metabolomics Method for Estimating Platelet Mitochondrial Oxygen Consumption Rates in Patients with Sepsis.

Metabolites

McCann MR, McHugh CE, Kirby M, Jennaro TS, Jones AE, Stringer KA, Puskarich MA.
PMID: 32252461
Metabolites. 2020 Apr 02;10(4). doi: 10.3390/metabo10040139.

BACKGROUND: Sepsis-induced alterations in mitochondrial function contribute to organ dysfunction and mortality. Measuring mitochondrial function in vital organs is neither feasible nor practical, highlighting the need for non-invasive approaches. Mitochondrial function may be reflected in the concentrations of metabolites...
