Pedicled flap transfer after chest wall malignant tumor resection and potential risk of postoperative respiratory problems for patients with low FEV1.0.

Introduction: Musculoskeletal transfer for chest wall tissue defects is a crucial method, and pedicled flaps around the chest wall are preferred in terms of location and simplicity of transfer. These require special care because of complications such as partial necrosis, fistula, wound dehiscence, infection, hematoma and restricted function of the arm or shoulder. However, studies of respiratory function are rare.

The Effect of Photodynamic Therapy Using 5-Aminolevulinic Acid in Bone and Soft Tissue Sarcoma Cells.

Background/aim: 5-Aminolevulinic acid (5-ALA) is a natural amino acid and a precursor of protoporphyrin IX (PpIX). Following light irradiation, the PpIX generates reactive oxygen species (ROS) in the presence of oxygen. Increased ROS levels can cause apoptotic cell death and necrosis of targeted cancer cells.

Gastric metastasis in patients with leiomyosarcoma: A case report.

Soft tissue sarcomas (STS) are very rare tumors, accounting for <1% of all malignancies. Leiomyosarcoma (LMS), accounts for 10-20% of STS. Gastric metastasis of LMS is extremely rare, and only a few cases have been reported.

Extracellular HSPA5 is autocrinally involved in the regulation of neuronal process elongation.

The molecular mechanisms by which neuronal processes grow are extremely complicated, involving fine-tuned regulation of extracellular and intracellular signals. It remains to be elucidated which molecules are contained in the regulation. Herein, we report for the first time that heat shock protein family A member 5 (HSPA5, also called immunoglobulin heavy chain binding endoplasmic reticulum [ER] protein [BiP]) is secreted from mouse primary dorsal neuronal ganglion (DRG) cells or neuronal cell line N1E-115, a frequently used neuronal differentiation model.

The Onset of Subtalar Joint Monoarthritis in a Patient with Rheumatoid Arthritis.

The involvement of the subtalar joint is uncommon in the early stages of rheumatoid arthritis (RA). We report a case of a 47-year-old female who had RA with isolated subtalar joint arthritis. The clinical history, magnetic resonance imaging, and pathological findings of the patient are presented.
