Structure and dynamics of thylakoids in land plants.

Journal of experimental botany

Pribil M, Labs M, Leister D.
PMID: 24622954
J Exp Bot. 2014 May;65(8):1955-72. doi: 10.1093/jxb/eru090. Epub 2014 Mar 12.

Thylakoids of land plants have a bipartite structure, consisting of cylindrical grana stacks, made of membranous discs piled one on top of the other, and stroma lamellae which are helically wound around the cylinders. Protein complexes predominantly located in...

Chlorophyll Fluorescence Video Imaging: A Versatile Tool for Identifying Factors Related to Photosynthesis.

Frontiers in plant science

Rühle T, Reiter B, Leister D.
PMID: 29472935
Front Plant Sci. 2018 Jan 30;9:55. doi: 10.3389/fpls.2018.00055. eCollection 2018.

Measurements of chlorophyll fluorescence provide an elegant and non-invasive means of probing the dynamics of photosynthesis. Advances in video imaging of chlorophyll fluorescence have now made it possible to study photosynthesis at all levels from individual cells to entire...

Structure-properties relationships in triarylamine-based donor-acceptor molecules containing naphtyl groups as donor material for organic solar cells.

Scientific reports

Mohamed S, Demeter D, Laffitte JA, Blanchard P, Roncali J.
PMID: 25761773
Sci Rep. 2015 Mar 12;5:9031. doi: 10.1038/srep09031.

The effects of replacing the phenyl rings of triphenylamine (TPA) by naphtyl groups are analysed on a series of push-pull molecules containing a 2-thienyl-dicyanovinyl acceptor group. UV-Vis absorption spectroscopy and cyclic voltammetry show that the introduction of one or...

Inflammatory Myofibroblastic Tumor of the Pancreatic Head: An Unusual Cause of Recurrent Acute Pancreatitis - Case Presentation of a Palliative Approach after Failed Resection and Review of the Literature.

Case reports in gastroenterology

Schütte K, Kandulski A, Kuester D, Meyer F, Wieners G, Schulz HU, Malfertheiner P.
PMID: 21113286
Case Rep Gastroenterol. 2010 Oct 18;4(3):443-451. doi: 10.1159/000320953.

Inflammatory myofibroblastic tumors (IMTs) are a rare cause of echo-poor pancreatic head enlargement. Histologically, IMTs are characterized by spindle-shaped myofibroblasts or fibroblasts accompanied by a mixed immune cell infiltration. The most common localizations of IMTs have been reported in...

Thylakoid redox signals are integrated into organellar-gene-expression-dependent retrograde signaling in the prors1-1 mutant.

Frontiers in plant science

Tadini L, Romani I, Pribil M, Jahns P, Leister D, Pesaresi P.
PMID: 23293642
Front Plant Sci. 2012 Dec 27;3:282. doi: 10.3389/fpls.2012.00282. eCollection 2012.

Perturbations in organellar gene expression (OGE) and the thylakoid redox state (TRS) activate retrograde signaling pathways that adaptively modify nuclear gene expression (NGE), according to developmental and metabolic needs. The prors1-1 mutation in Arabidopsis down-regulates the expression of the...

Sex-specific timing of meiotic initiation is regulated by Cyp26b1 independent of retinoic acid signalling.

Nature communications

Kumar S, Chatzi C, Brade T, Cunningham TJ, Zhao X, Duester G.
PMID: 21224842
Nat Commun. 2011 Jan 11;2:151. doi: 10.1038/ncomms1136.

Sex-specific initiation of meiosis in the fetal ovary has been suggested to require retinoic acid (RA) for induction of Stra8, with expression of the RA-degrading enzyme Cyp26b1 in fetal testis delaying meiosis until postnatal development. In this study, we...

Delayed esophageal perforation from stereotactic body radiation therapy for locally recurrent central nonsmall cell lung cancer.

Lung India : official organ of Indian Chest Society

Sainathan S, Wu LD, Andaz S.
PMID: 24778482
Lung India. 2014 Apr;31(2):158-60. doi: 10.4103/0970-2113.129854.

Stereotactic body radiation therapy (SBRT) is a novel form of external beam radiation therapy. It is used to treat early and locally recurrent nonsmall cell lung cancer (NSLC) in medically inoperable patients. It uses high dose, hypofractionated radiotherapy, with...

Gallium-nitride-based plasmonic multilayer operating at 1.55 μm.

Optics letters

Stolz A, Considine L, Faci S, Dogheche E, Tripon-Canseliet C, Loiseaux B, Pavlidis D, Decoster D, Chazelas J.
PMID: 22859078
Opt Lett. 2012 Aug 01;37(15):3039-41. doi: 10.1364/OL.37.003039.

In this Letter, we have designed and fabricated a III-V semiconductor multilayer based on surface plasmon resonance (SPR) operating at the telecom wavelength. Optimization of the optogeometrical parameters and the metal/semiconductor layers required for this novel structure was conducted...

Optical-field-induced current in dielectrics.

Nature

Schiffrin A, Paasch-Colberg T, Karpowicz N, Apalkov V, Gerster D, Mühlbrandt S, Korbman M, Reichert J, Schultze M, Holzner S, Barth JV, Kienberger R, Ernstorfer R, Yakovlev VS, Stockman MI, Krausz F.
PMID: 23222521
Nature. 2013 Jan 03;493(7430):70-4. doi: 10.1038/nature11567. Epub 2012 Dec 05.

The time it takes to switch on and off electric current determines the rate at which signals can be processed and sampled in modern information technology. Field-effect transistors are able to control currents at frequencies of the order of...
