A Case of Bifid Mandibular Condyle
Bifid mandibular condyle is a rare anatomic anomaly that can result from congenital malformation, trauma, infection or tumor. We report a case of bifid mandibular condyle found after head injury. A bifid mandibular condyle was seen on the computed tomographic scan of a 41-year-old man after a car accident. The patient had asymmetry in the condylar angle and length of the condylar neck, and anomaly of occlusion resulting from many residual roots with deep caries. Mouth-opening and mandibular movements were normal, however, the presence of temporomandibular joint symptoms was unclear because of the patientâs unconsciousness at the time of the scan. The bifid mandibular condyle could have resulted from a bicycle accident when the patient was 7 years of age, based on information from the patientâs family.Isomura ET, Kobashi H, Tanaka S, Enomoto A, Kogo M (2017) A Case of Bifid Mandibular Condyle.

Clinical application of endoscopic soft palate augmentation in the treatment of velopharyngeal insufficiency
Velopharyngeal structure augmentation with the injection of autologous fat tissue into the nasal mucosa of the soft palate has been reported previously. However, as the injection points in the velopharyngeal space cannot be observed directly, these injections may be difficult to perform accurately. This report describes a new endoscope-assisted approach in which the materials for velopharyngeal structure augmentation are administered while observing the injection points directly, also enabling adjustment of the amount of material injected. A case series of five patients aged 8â16 years who underwent endoscopic soft palate augmentation under general anaesthesia is reported. Autologous fat tissue was injected into the nasal mucosa of the soft palate using a needle-type device of an endoscope, and the effects of the treatment were evaluated. The injections were performed successfully, and the velopharyngeal function was improved. This new technique of endoscopy-assisted augmentation was useful for the treatment of velopharyngeal insufficiency.Isomura E.T., Matsukawa M., Yokota Y., et al.

Influence of oxygen-coordination number on the electronic structure of single-layer La-based cuprates
We present an angle-resolved photoemission spectroscopy study of the
single-layer T*-type structured cuprate SmLaSrCuO with unique
five-fold pyramidal oxygen coordination. Upon varying oxygen content,
T*-SmLaSrCuO evolved from a Mott-insulating to a metallic state
where the Luttinger sum rule breaks down under the assumption of a large
hole-like Fermi surface. This is in contrast with the known doping evolution of
the structural isomer LaSrCuO with six-fold octahedral
coordination. In addition, quantitatively characterized Fermi surface suggests
that the empirical rule for octahedral oxygen-coordination
systems does not apply to T*-SmLaSrCuO. The present results
highlight unique properties of the T*-type cuprates possibly rooted in its
oxygen coordination, and necessitate thorough investigation with careful
evaluation of disorder effects.Comment: Accepted for publication in Phys. Rev.
A Molecular Platinum Cluster Junction: A Single-Molecule Switch
We present a theoretical study of the electronic transport through
single-molecule junctions incorporating a Pt6 metal cluster bound within an
organic framework. We show that the insertion of this molecule between a pair
of electrodes leads to a fully atomically engineered nano-metallic device with
high conductance at the Fermi level and two sequential high on/off switching
states. The origin of this property can be traced back to the existence of a
HOMO which consists of two degenerate and asymmetric orbitals, lying close in
energy to the Fermi level of the metallic leads. Their degeneracy is broken
when the molecule is contacted to the leads, giving rise to two resonances
which become pinned close to the Fermi level and display destructive
interference.Comment: 4 pages, 4 figures. Reprinted (adapted) with permission from J. Am.

Fuzzy species limits in Mediterranean gorgonians (Cnidaria, Octocorallia): inferences on speciation processes
The study of the interplay between speciation and hybridization is of primary importance in evolutionary biology. Octocorals are ecologically important species whose shallow phylogenetic relationships often remain to be studied. In the Mediterranean Sea, three congeneric octocorals can be observed in sympatry: Eunicella verrucosa, Eunicella cavolini and Eunicella singularis. They display morphological differences and E.singularis hosts photosynthetic Symbiodinium, contrary to the two other species. Two nuclear sequence markers were used to study speciation and gene flow between these species, through network analysis and Approximate Bayesian Computation (ABC). Shared sequences indicated the possibility of hybridization or incomplete lineage sorting. According to ABC, a scenario of gene flow through secondary contact was the best model to explain these results. At the intraspecific level, neither geographical nor ecological isolation corresponded to distinct genetic lineages in E.cavolini. These results are discussed in the light of the potential role of ecology and genetic incompatibilities in the persistence of species limits.French National Research Agency (ANR) program Adacni (ANR) [ANR-12-ADAP-0016]CNRSHubert Curien 'Tassili' program [12MDU853]CCMAR Strategic Plan from Fundacao para a Ciencia e a Tecnologia-FCT [PEst-C/MAR/LA0015/2011,FEDERinfo:eu-repo/semantics/publishedVersio
c-Rel is required for the development of thymic Foxp3+ CD4 regulatory T cells
During thymopoiesis, a unique program of gene expression promotes the development of CD4 regulatory T (T reg) cells. Although Foxp3 maintains a pattern of gene expression necessary for T reg cell function, other transcription factors are emerging as important determinants of T reg cell development. We show that the NF-ÎșB transcription factor c-Rel is highly expressed in thymic T reg cells and that in c-relâ/â mice, thymic T reg cell numbers are markedly reduced as a result of a T cellâintrinsic defect that is manifest during thymocyte development. Although c-Rel is not essential for TGF-ÎČ conversion of peripheral CD4+CD25â T cells into CD4+Foxp3+ cells, it is required for optimal homeostatic expansion of peripheral T reg cells. Despite a lower number of peripheral T reg cells in c-relâ/â mice, the residual peripheral c-relâ/â T reg cells express normal levels of Foxp3, display a pattern of cell surface markers and gene expression similar to those of wild-type T reg cells, and effectively suppress effector T cell function in culture and in vivo. Collectively, our results indicate that c-Rel is important for both the thymic development and peripheral homeostatic proliferation of T reg cells
Measles vaccine coverage and factors related to uncompleted vaccination among 18-month-old and 36-month-old children in Kyoto, Japan
BACKGROUND: Due to low vaccine coverage, Japan has not only experienced outbreaks of measles but has also been exporting it overseas. This study aims to survey measles vaccine coverage and the factors uncompleted vaccination among community-living children. METHODS: Subjects were the parents whose children had undergone either an 18-month or a 36-month checkup publicly provided by Kyoto City during November 2001 to January 2002. An anonymous self-administered questionnaire survey was conducted. RESULTS: The coverage was 73.2% among the 18-month-old children (n = 2707) and 88.9% among the 36-month-old children (n = 2340), respectively. The following characteristics of mothers were related to uncompleted measles vaccination: aged below 30, working, concerned about the adverse events of the vaccine, and had insufficient knowledge. Similarly, the following characteristics among children were related to uncompleted measles vaccination: not the first-born child, interacting with other children in group settings. The coverage was the lowest among the children whose mothers were concerned about the adverse events of the vaccine without proper knowledge of measles and its vaccination. CONCLUSION: To increase vaccine coverage among children, parents' awareness about measles and vaccination against it should be promoted, especially for working mothers. Efforts to enhance access to vaccination services and to communicate with parents about changing vaccination schedules are necessary
