Conservative reduction by lever action of chronic bilateral mandibular condyle dislocation.

Aims: The treatment of long-standing dislocation of the temporomandibular joint is broadly classified into open reduction and closed reduction. The current study presents a case of long-standing dislocation of the temporomandibular joint treated 3 years after dislocation. In this study, the authors evaluated the long-term outcome of conservative reduction by lever action of chronic bilateral mandibular condyle dislocation.

Expression of protocadherin-19 in the nervous system of the embryonic zebrafish.

We have analyzed the expression pattern of protocadherin-19, a member of the delta2-protocadherins, in the nervous system of developing zebrafish using in situ hybridization methods. mRNA encoding protocadherin-19 (Pcdh19) began to be expressed at about 12 hours post fertilization (hpf) showing a segmental expression pattern in the anterior 1/3 of the neural keel, with strong expression in the presumptive forebrain, cerebellum/rhombomere 1 and rhombomere 4. Pcdh19 expression in the posterior neural keel was continuous and confined to the midline region.

VAMP2 is expressed in myogenic cells during rat development.

Vesicle-associated membrane protein 2 (VAMP2) is a member of the SNARE family of proteins that regulate the intracellular vesicle fusion process. This study investigated the developmental expression of VAMP2 in the rat embryo. In the trunk, VAMP2 was primarily found in the heart on embryonic day (E) 10.

Cadherin-6 function in zebrafish retinal development.

Cadherin cell-adhesion molecules play crucial roles in vertebrate development including the development of the visual system. Most studies have focused on examining functions of classical type I cadherins (e.g.

Expression of protocadherin 18 in the CNS and pharyngeal arches of zebrafish embryos.

Here, we report the results of molecular cloning and expression analyses of a non-clustered protocadherin (pcdh), pcdh18 in zebrafish embryos. The predicted zebrafish pcdh18 protein shows 6566% identity and 7879% homology with its mammalian and Xenopus counterparts. It has a Disabled-1 binding motif in its cytoplasmic domain, which is characteristic of pcdh18.

Cadherin-6 is required for zebrafish nephrogenesis during early development.

We performed functional analyses of cadherin-6 (cdh6) in zebrafish nephrogenesis using antisense morpholino oligonucleotide (MO) inhibition combined with in situ hybridization. We have cloned a zebrafish homolog (accession number AB193290) of human K-cadherin (CDH6), which showed 6063% identity and 7678% similarity to the human, mouse, chicken and Xenopus homologs. Whole-mount in situ hybridization showed that cdh6 is expressed in the pronephric ducts and nephron primordia in addition to the central and peripheral nervous systems.
