Pharmacokinetics of Hydrogen During Hydrogen-Saturated Saline Infusion in Pigs.

: Hydrogen gas (H) has been shown to be effective in the treatment of various clinical conditions, from acute illnesses to chronic illnesses. However, its clinical indications and the corresponding appropriate hydrogen delivery methods have yet to be determined. This is due to the fact that the pharmacokinetics and pharmacodynamics of hydrogen in each delivery method have not been experimentally proven.

Intraoperative tumor capsule injury in patients with renal cell carcinoma receiving partial nephrectomy.

Objective: We investigated the impact of intraoperative tumor capsule injury (TCI) during robot-assisted partial nephrectomy (RAPN) or laparoscopic partial nephrectomy (LPN) on oncological outcomes, as well as underlying factors of intraoperative TCI for improving surgical outcomes.

Methods: A total of 253 patients who underwent RAPN or LPN between 2010 and 2022 were retrospectively analyzed and were divided into two groups: non-TCI and TCI groups. The background was compared between two groups.

DEAD/H Box 5 (DDX5) Augments E2F1-Induced Cell Death Independent of the Tumor Suppressor p53.

In almost all cancers, the p53 pathway is disabled and cancer cells survive. Hence, it is crucially important to induce cell death independent of p53 in the treatment of cancers. The transcription factor E2F1 is controlled by binding of the tumor suppressor pRB, and induces apoptosis by activating the gene, an upstream activator of p53, when deregulated from pRB by loss of pRB function.

Differential effects of structurally different lysophosphatidylethanolamine species on proliferation and differentiation in pre-osteoblast MC3T3-E1 cells.

Lysophosphatidylethanolamine (LPE) is a bioactive lipid mediator involved in diverse cellular functions. In this study, we investigated the effects of three LPE species, 1-palmitoyl LPE (16:0 LPE), 1-stearoyl LPE (18:0 LPE), and 1-oleoyl LPE (18:1 LPE) on pre-osteoblast MC3T3-E1 cells. All LPE species stimulated cell proliferation and activated the mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) 1/2.

Temporomandibular joint ganglion-induced external auditory canal obstruction associated with osteoarthritis: a case report.

Ganglions are pseudocysts that develop from part of the joint capsule or tendon sheath and are filled with synovial fluid. In this report, we describe a case of external auditory canal obstruction caused by a temporomandibular joint (TMJ) ganglion that was thought to be related to osteoarthritis. A 62-year-old man with the chief complaint of swelling of the anterior wall of the left external auditory canal underwent cystectomy at the Department of Otorhinolaryngology.
