From Accumulation to Degradation: Reprogramming Polyamine Metabolism Facilitates Dark-Induced Senescence in Barley Leaf Cells.

Frontiers in plant science

Sobieszczuk-Nowicka E, Kubala S, Zmienko A, Małecka A, Legocka J.
PMID: 26779231
Front Plant Sci. 2016 Jan 06;6:1198. doi: 10.3389/fpls.2015.01198. eCollection 2015.

The aim of this study was to analyze whether polyamine (PA) metabolism is involved in dark-induced Hordeum vulgare L. 'Nagrad' leaf senescence. In the cell, the titer of PAs is relatively constant and is carefully controlled. Senescence-dependent increases in...

γ-Aminobutyric Acid (GABA) Accumulation in Tea (Camellia sinensis L.) through the GABA Shunt and Polyamine Degradation Pathways under Anoxia.

Journal of agricultural and food chemistry

Liao J, Wu X, Xing Z, Li Q, Duan Y, Fang W, Zhu X.
PMID: 28355482
J Agric Food Chem. 2017 Apr 12;65(14):3013-3018. doi: 10.1021/acs.jafc.7b00304. Epub 2017 Apr 04.

γ-Aminobutyric acid (GABA) is an important bioactive component of tea (Camellia sinensis) providing various health benefits. We studied GABA accumulation via the GABA shunt and polyamine degradation pathways under anoxia in tea leaves. Anoxia caused a ∼20-fold increment in...

Nonclassicality phase-space functions: more insight with fewer detectors.

Physical review letters

Luis A, Sperling J, Vogel W.
PMID: 25815932
Phys Rev Lett. 2015 Mar 13;114(10):103602. doi: 10.1103/PhysRevLett.114.103602. Epub 2015 Mar 11.

Systems of on-off detectors are well established for measuring radiation fields in the regime of small photon numbers. We propose to combine these detector systems with unbalanced homodyning with a weak local oscillator. This approach yields phase-space functions, which...

Mutations in NEBL encoding the cardiac Z-disk protein nebulette are associated with various cardiomyopathies.

Archives of medical science : AMS

Perrot A, Tomasov P, Villard E, Faludi R, Melacini P, Lossie J, Lohmann N, Richard P, De Bortoli M, Angelini A, Varga-Szemes A, Sperling SR, Simor T, Veselka J, Özcelik C, Charron P.
PMID: 27186169
Arch Med Sci. 2016 Apr 01;12(2):263-78. doi: 10.5114/aoms.2016.59250. Epub 2016 Apr 11.

INTRODUCTION: Transgenic mice overexpressing mutated NEBL, encoding the cardiac-specific Z-disk protein nebulette, develop severe cardiac phenotypes. Since cardiomyopathies are commonly familial and because mutations in a single gene may result in variable phenotypes, we tested the hypothesis that NEBL...

Synthesis and application of magnetite dextran-spermine nanoparticles in breast cancer hyperthermia.

Progress in biomaterials

The synthesis of two new azobenzene dyes, namely CR-528 and CR-555, and their spectral properties in ethanol solution are described. The recognition of sulfur-containing analytes (2-mercaptoethanol (2-ME), sodium hydrosulfide (NaHS)), and biogenic amines (spermine, spermidine, ethanolamine) bestowed significant spectral...

Host-guest recognition-induced color change of water-soluble pillar[5]arene modified silver nanoparticles for visual detection of spermine analogues.
