Shock assisted ionization injection in laser-plasma accelerators.

Scientific reports

Thaury C, Guillaume E, Lifschitz A, Ta Phuoc K, Hansson M, Grittani G, Gautier J, Goddet JP, Tafzi A, Lundh O, Malka V.
PMID: 26549584
Sci Rep. 2015 Nov 09;5:16310. doi: 10.1038/srep16310.

Ionization injection is a simple and efficient method to trap an electron beam in a laser plasma accelerator. Yet, because of a long injection length, this injection technique leads generally to the production of large energy spread electron beams....

Hydrodynamic evolution of plasma waveguides for soft-x-ray amplifiers.

Physical review. E

Oliva E, Depresseux A, Cotelo M, Lifschitz A, Tissandier F, Gautier J, Maynard G, Velarde P, Sebban S.
PMID: 29548124
Phys Rev E. 2018 Feb;97(2):023203. doi: 10.1103/PhysRevE.97.023203.

High-density, collisionally pumped plasma-based soft-x-ray lasers have recently delivered hundreds of femtosecond pulses, breaking the longstanding barrier of one picosecond. To pump these amplifiers an intense infrared pulse must propagate focused throughout all the length of the amplifier, which...

Allosteric supramolecular coordination constructs.

Journal of the American Chemical Society

Lifschitz AM, Rosen MS, McGuirk CM, Mirkin CA.
PMID: 26035450
J Am Chem Soc. 2015 Jun 17;137(23):7252-61. doi: 10.1021/jacs.5b01054. Epub 2015 Jun 02.

Coordination chemistry is regularly used to generate supramolecular constructs with unique environments around embedded components to affect their intrinsic properties. In certain cases, it can also be used to effect changes in supramolecular structure reminiscent of those that occur...

Chemical mate recognition and release of male sexual behavior in polybiine wasp,Belonogaster petiolata (Degeer) (Hymenoptera: Vespidae).

Journal of chemical ecology

Keeping MG, Lipschitz D, Crewe RM.
PMID: 24306915
J Chem Ecol. 1986 Mar;12(3):773-9. doi: 10.1007/BF01012109.

The results of bioassays using freshly killed gynes ofBelonogaster petiolata (Degeer) and hexane extracts of their tagmata and abdominal glands provide evidence for the existence of chemical signals in the venom, thorax, and head of gynes that serve as...

Methanol Intoxication Victims are Suitable Donors for Corneal Transplantation.

Cell and tissue banking

Lifshitz M, Gavrilov V, Lifshitz T.
PMID: 15256958
Cell Tissue Bank. 2000;1(2):129-31. doi: 10.1023/A:1010180032383.

Purpose. To evaluate the outcome of corneal transplantation and the feasibility of tissue donation from donors with methanol intoxication.Methods. Four corneas from two methanol intoxication victims were procured and transplanted in four patients at our medical center. The outcome...

Boron-dipyrromethene-functionalized hemilabile ligands as "turn-on" fluorescent probes for coordination changes in weak-link approach complexes.

Inorganic chemistry

Lifschitz AM, Shade CM, Spokoyny AM, Mendez-Arroyo J, Stern CL, Sarjeant AA, Mirkin CA.
PMID: 23570551
Inorg Chem. 2013 May 06;52(9):5484-92. doi: 10.1021/ic400383t. Epub 2013 Apr 09.

Herein we report a new class of hemilabile ligands with boron-dipyrromethene (Bodipy) fluorophores that, when complexed to Pt(II), can signal changes in coordination mode through changes in their fluorescence. The ligands consist of phosphino-amine or phosphino-thioether coordinating moieties linked...

PlantRNA_Sniffer: A SVM-Based Workflow to Predict Long Intergenic Non-Coding RNAs in Plants.

Non-coding RNA

Vieira LM, Grativol C, Thiebaut F, Carvalho TG, Hardoim PR, Hemerly A, Lifschitz S, Ferreira PCG, Walter MEMT.
PMID: 29657283
Noncoding RNA. 2017 Mar 04;3(1). doi: 10.3390/ncrna3010011.

Non-coding RNAs (ncRNAs) constitute an important set of transcripts produced in the cells of organisms. Among them, there is a large amount of a particular class of long ncRNAs that are difficult to predict, the so-called long intergenic ncRNAs...

Potassium homeostasis and dyskalemias: the respective roles of renal, extrarenal, and gut sensors in potassium handling.

Kidney international supplements

Epstein M, Lifschitz MD.
PMID: 30675414
Kidney Int Suppl (2011). 2016 Apr;6(1):7-15. doi: 10.1016/j.kisu.2016.01.006. Epub 2016 Mar 14.

Integrated mechanisms controlling the maintenance of potassium homeostasis are well established and are defined by the classic "feedback control" of potassium balance. Recently, increasing investigative attention has focused on novel physiological paradigms that increase the complexity and precision of...

Florigen and anti-florigen - a systemic mechanism for coordinating growth and termination in flowering plants.

Frontiers in plant science

Lifschitz E, Ayre BG, Eshed Y.

Front Plant Sci. 2014 Sep 16;5:465. doi: 10.3389/fpls.2014.00465. eCollection 2014.

Genetic studies in Arabidopsis established FLOWERING LOCUS T (FT) as a key flower-promoting gene in photoperiodic systems. Grafting experiments established unequivocal one-to-one relations between SINGLE FLOWER TRUSS (SFT), a tomato homolog of FT, and the hypothetical florigen, in all...
