Dear Editor,Beige adipocytes,which increase energy expenditure by dissipating energy as heat,have gained attention as a therapeutic target for combating obesity.1 Adipocytes express many types of G-protein-coupled receptors(GPCRs),each of which has a unique preference for the Gs,Gi,Gq,and G12 *** the function of Gs-coupledβ-adrenergic receptors in beige adipocyte induction is well established,2 little is known about the function of G12-coupled GPCRs beyond its suppressive roles in white adipocyte maturation.3 In this study,we generated transgenic mice conditionally expressing a G12-coupled designer GPCR using a Cre-loxP system and investigated the potential effects of G12 signaling on adipocyte biology.

Does There Exist the Applicability Limit of PDE to Describe Physical Phenomena?—A Personal Survey of Quantization, QED, Turbulence

引用

World Journal of Mechanics 2024年第6期14卷 97-142页

作者： Atsushi inoue Department of Mathematics Tokyo Institute of Technology Tokyo Japan

What does it mean to study PDE (Partial Differential Equation)? How and what to do “to claim proudly that I’m studying a certain PDE”? Newton mechanic uses mainly ODE (Ordinary Differential Equation) and describes nicely movements of Sun, Moon and Earth etc. Now, so-called quantum phenomenum is described by, say Schrödinger equation, PDE which explains both wave and particle characters after quantization of ODE. The coupled Maxwell-Dirac equation is also “quantized” and QED (Quantum Electro-Dynamics) theory is invented by physicists. Though it is said this QED gives very good coincidence between theoretical1 and experimental observed quantities, but what is the equation corresponding to QED? Or, is it possible to describe QED by “equation” in naive sense?

A Case of Warthin’s Tumor Together with IgG4-Related Sialadenitis

引用

Open Journal of Pathology 2024年第3期14卷 81-89页

作者： Ryogo Aoki Risa Ito asuka Ohashi Riyoko Niwa Masashi Matsuyama Sachiko Oka Naomi Kawaguchi Toshimasa Sakakima Daichi Kodama Naoki Watanabe Daisuke Okamoto Takafumi Naiki Takuji Tanaka Department of Diagnostic Pathology (DDP) & Research Center of Diagnostic Pathology (RC-DiP) Gifu Municipal Hospital Gifu Japan Department of Central Clinical Laboratory Gifu Municipal Hospital Gifu Japan Department of Hematology Gifu Municipal Hospital Gifu Japan

Warthin’s tumor is the second most frequent neoplasm next to pleomorphic adenoma in the salivary gland. The tumor contains the epithelial oncocyte cells with the presence of rich-mitochondria and their surrounding abundant lymphocytes. A relatively new disease entity of IgG4-related disease frequently occurs in the salivary gland. However, the coexistence of Warthin’s tumor and IgG4-related disease is scarcely observed. We have recently experienced a rare case of Warthin’s tumor with IgG4-related sialadenitis. A 51-year-old man presented to our hospital, complaining of a mass with right submandibular tenderness and spontaneous pain. A computed tomography scan of the cervical region revealed a suspicion of lymph node proliferative disease, including malignant lymphoma. Elevated serum levels of IL-2R: 1843 U/ml (reference value 122 - 496 U/ml), IgG: 3430 mg/dl (reference value 861 - 1747 mg/dl), and IgG4: 3140 mg/dl (reference value 11 - 121 mg/dl) were observed. Other laboratory data showed within normal ranges. The cervical tumor was diagnosed as Warthin’s tumor by the findings of fine-needle aspiration cytology and biopsy examination. Immunohistochemistry revealed numerous IgG4- and IgG-positive cells with fibrosis surrounding the epithelial component of Warthin’s tumor, suggesting IgG4-rerated sialadenitis. Finally, we diagnosed the cervical tumor as Warthin tumor with IgG4-related sialadenitis. This is the second report describing a case of Warthin’s tumor with possible involvement of IgG4-related sialadenitis.
