In plants, the phytohormone auxin acts as a master regulator of developmental processes and environmental responses. The best characterized process in the auxin regulatory network occurs at the subcellular scale, wherein auxin mediates signal transduction into transcriptional programs by triggering the degradation of Aux/IAA transcriptional repressor proteins in the nucleus. However, whether and how auxin movement between the nucleus and the surrounding compartments is regulated remain elusive.

Hydroxyapatites: Key Structural Questions and Answers from Dynamic Nuclear Polarization.

Anal Chem

October 2017

Sorbonne Universités, UPMC Université Paris 06, CNRS, Collège de France, Laboratoire de Chimie de la Matière Condensée de Paris (LCMCP) UMR 7574, 4 Place Jussieu, 75252 Paris Cedex 05, France.

We demonstrate that NMR/DNP (Dynamic Nuclear Polarization) allows an unprecedented description of carbonate substituted hydroxyapatite (CHAp). Key structural questions related to order/disorder and clustering of carbonates are tackled using distance sensitive DNP experiments using C-C recoupling. Such experiments are easily implemented due to unprecedented DNP gain (orders of magnitude).

Correction of the Lower Lip With a Cartilage Graft and Lip Resection in Patients With Facioscapulohumeral Muscular Dystrophy.

J Craniofac Surg

September 2016

Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Science, University of Okayama, Okayama, Japan.

Facioscapulohumeral muscular dystrophy is an autosomal-dominant, slowly progressive myopathy that involves facial, shoulder, and upper arm muscles. Facial muscle atrophy and weakness leads to drooping of the lower lip, which has unfavorable functional and aesthetic outcomes. While there are several methods to correct drooping of the lower lip, including lip resection, free vascularized muscle transfer, and fascia suspension, there are no reports describing the use of an auricular cartilage graft to elevate the lip.

The clock network of Drosophila melanogaster expresses various neuropeptides, but a function in clock-mediated behavioral control was so far only found for the neuropeptide pigment dispersing factor (PDF). Here, we propose a role in the control of behavioral rhythms for the ion transport peptide (ITP), which is expressed in the fifth small ventral lateral neuron, one dorsal lateral neuron, and in only a few nonclock cells in the brain. Immunocytochemical analyses revealed that ITP, like PDF, is most probably released in a rhythmic manner at projection terminals in the dorsal protocerebrum.

The drop-down technique as an optimal technique for back-wall end-to-side anastomosis.

J Craniofac Surg

July 2014

From the *Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, The University of Tokyo, Tokyo; and †Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Science, University of Okayama, Okayama, Japan.

An advantage of end-to-side anastomosis is that thrombogenesis in the anastomotic part is less likely than with end-to-end anastomosis. Conversely, the operative procedure for end-to-side anastomosis is more complicated than that of end-to-end anastomosis. We usually perform a modified back-wall technique in which the outflow vessel is dropped over the inflow vessel.
