Synovial chondromatosis (SC) is a rare benign disease involving multifocal generation of ectopic cartilage in the synovial tissue. Herein, we report two cases of SC in the temporomandibular joint: a 38-year-old woman (patient 1) and 39-year-old woman (patient 2). Both patients had trismus, jaw joint noises, and jaw-opening pain in the temporomandibular joint.

Background: Adiponectin-transgenic mice had many small adipocytes in both subcutaneous and visceral adipose tissues, and showed higher sensitivity to insulin, longer life span, and reduced chronic inflammation. We hypothesized that adiponectin regulates Wnt signaling in adipocytes and thereby modulates adipocyte proliferation and chronic inflammation in adipose tissue.

Materials And Methods: We examined the expression of all Wnt ligands and their receptors and the activity of Wnt signaling pathways in visceral adipose tissue from wild-type mice and two lines of adiponectin-transgenic mice.

In this study, we examined whether adiponectin suppresses endoplasmic reticulum (ER) stress in nonalcoholic steatohepatitis (NASH) using male transgenic mice expressing nSREBP-1c in adipose tissue, nSREBP-1c/adiponectin double-transgenic mice expressing human adiponectin in the liver, and wild-type male mice as the control. Histological findings similar to those observed in liver specimens from patients with NASH were observed in the livers from the nSREBP-1c transgenic mice at 30 weeks of age. By contrast, the NASH-like liver histology was markedly attenuated in age-matched nSREBP-1c/adiponectin double-transgenic mice.

We previously reported that transgenic (Tg) expression of adiponectin significantly prolonged the lifespan of normal mice. The aim of this study was to elucidate the mechanism involved in the longevity effects of adiponectin using KK/Ta mice, a murine model of metabolic syndrome. We established a Tg line of KK/Ta (Tg-KK/Ta) mice expressing human adiponectin in the liver, and assessed their lifespan.

The rat controls the form of its tail, from straight to curved, by contraction and relaxation of its four tail muscles. The tendons of these muscles insert on any of the cranial articular, transverse, and hemal processes of each of 24 coccygeal vertebrae (Co5-Co28). In this study, we isolated for the four coccygeal muscles each muscular fascicle segment inserting on any process of the coccygeal vertebrae.

The ruthenium-catalyzed oxidative vinylation of thiophene-2-carboxylic acids with alkenes efficiently proceeds through directed C-H bond cleavage to give the corresponding 3-vinylated products. Similarly, benzothiophene-, benzofuran-, pyrrole-, and indolecarboxylic acids also undergo regioselective vinylation.

Nitric oxide (NO) has various roles in the skeletal musculature in both normal and pathological conditions. NO primarily activates soluble guanylate cyclase (sGC) and mediates subsequent intracellular signaling in target cells. We sought to identify the target cells of NO in the rat skeletal musculature, using subtypes of sGCalpha1 and sGCbeta1 antibodies.

The aim of the study is to identify the clinical characteristics of Japanese patients with young-onset type 2 diabetes (YT2D). Family history of diabetes and clinical data were collected for 30 unrelated males (from 11 to 20 years old at age of onset) and 20 females (from 10 to 20 years old at age of onset) with YT2D diagnosed at ≤ 20 years of age. Fasting C-peptide levels were measured in all, and glucagon stimulation tests were performed twice in six of them over several years.

We have previously reported that transgenic mice expressing nuclear sterol regulatory element-binding protein 1c (nSREBP-1c) in adipose tissue under the control of aP2 promoter, an inherited lipodystrophic model with insulin resistance and fatty liver, developed with age liver lesions similar to those of human nonalcoholic steatohepatitis (NASH). Because the spontaneous NASH model mice had marked hypoadiponectinemia, here we assessed the effect of adiponectin transgenically expressed in the liver of nSREBP-1c transgenic mice. The nSREBP-1c/adiponectin double-transgenic mice showed hepatic adiponectin production and restored circulating adiponectin levels.

Background: The polymorphism of the protein tyrosine phosphatase nonreceptor 22 (PTPN22) gene, which encodes an important negative regulator of T cell activation, has been reported to be associated with susceptibility to Graves' disease (GD) in Caucasians. The objective of this study was to investigate whether PTPN22 gene polymorphisms confer susceptibility to GD and Graves' ophthalmopathy (GO) in a Japanese population.

Methods: We performed a case-control study of PTPN22 gene polymorphisms in Japanese GD patients (n = 414) and healthy control subjects with no antithyroid autoantibodies or family history of autoimmune disorders (n = 231).

We aimed to define the detailed clinical features of Japanese childhood-onset Type 2 diabetes mellitus (T2DM) patients who were followed-up, and to determine whether discernable characteristics were dissimilar or not from those of adult- and childhood-onset T2DM in other countries. Subjects were 22 patients (10 males and 12 females) under treatment without HNF-1alpha or mitochondrial gene mutations, and who were apparently diagnosed as diabetic when less than 15 years of age. Body mass indexes at onset in boys and girls were 25.

Adiponectin, a physiologically active polypeptide secreted by adipocytes, shows insulin-sensitizing, anti-inflammatory, and antiatherogenic properties in rodents and humans. To assess the effects of chronic hyperadiponectinemia on metabolic phenotypes, we established three lines of transgenic mice expressing human adiponectin in the liver. When maintained on a high-fat/high-sucrose diet, mice of two lines that had persistent hyperadiponectinemia exhibited significantly decreased weight gain associated with less fat accumulation and smaller adipocytes in both visceral and subcutaneous adipose tissues.

Nonalcoholic steatohepatitis (NASH) is one of the life-threatening hepatic diseases associated with insulin resistance. Here we report that nuclear sterol regulatory element-binding protein 1c (nSREBP-1c) transgenic mice, an inherited lipodystrophic model with severe insulin resistance, spontaneously develop steatohepatitis. The animal had marked fatty liver accompanied by hyperglycemia, hypoleptinemia, and hypoadiponectinemia.

Objective: To investigate whether polymorphisms of interleukin (IL)-18 gene confer susceptibility to Graves' disease (GD) and Graves' ophthalmopathy (GO).

Design: We performed a case control study on polymorphisms of IL-18 gene in Japanese patients with GD (n = 435), and healthy control subjects without antithyroid autoantibodies or family history of autoimmune disorders (n = 255). The C-4675G, C-607A, and G-137C polymorphisms in the promoter region and A105C (exon 5) polymorphism were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) using restriction enzymes, sequence-specific PCR, and PCR-direct sequencing methods.
