Reducing effect of feeding powdered nacre of Pinctada maxima on the visceral fat of rats.

An abdominal fat accumulation complicated by high blood triglycerides is regarded as a risk factor of metabolic syndrome. Feeding powdered nacre, mother of pearl, from Pinctada maxima, resulted in reduced body weight, visceral fat amount, and blood triglyceride level without influencing the food intake, body length, or amount of muscular tissue, suggesting that nacre powder specifically could decrease visceral fat.

Effects of estradiol and progesterone on the proinflammatory cytokine production by mononuclear cells from patients with chronic hepatitis C.

Aim: To investigate the effects of estradiol (E2) and progesterone on the unstimulated and oxidative stress-stimulated production of tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, IL-8, and macrophage chemotactic protein (MCP)-1 by peripheral blood mononuclear cells (PBMCs) from patients with chronic hepatitis C and healthy controls.

Methods: The PBMCs were separated from age-matched 72 males and 71 females with and without chronic hepatitis C, who were divided into two groups based on a mean menopausal age of 50 years. Oxidative stress was induced by hydrogen peroxide in the cells incubated in serum-free media.

A patient with spinal metastasis from hepatocellular carcinoma discovered from neurological findings.

Although spinal tumors are uncommon, they may reduce survival or cause serious functional disorders in the extremities. Metastatic spinal tumors from malignant tumors can induce symptoms of spinal cord compression, such as paraplegia, quadriplegia, and vesicorectal disturbance, which are aggravated with progression of the diseases and time. We report a patient with hepatocellular carcinoma (HCC) who was suspected of having spinal lesions based on neurological findings, and a metastatic spinal tumor was found by imaging examination.

Influence of an artificial pleural effusion technique on cardio-pulmonary function and autonomic activity.

Objective: Percutaneous treatment of hepatocellular carcinoma (HCC) located directly under the diaphragm is problematic because ultrasonic imaging is difficult, and the lung may be injured during the procedure. It has been reported that an infusion of 5% glucose solution into the thoracic cavity enables percutaneous treatment in such cases. However, the safety aspects of this have not been investigated.

Double radiofrequency ablation is more extensive with a spherical zone shape compared to single ablation in a pig liver model.

Objective: We compared the duration of ablation and the area of coagulation necrosis between a single ablation method (SAM) and a double ablation method (DAM) with a 'multitined expandable' electrode (LeVeen 2 cm) for radiofrequency ablation (RFA) using pig liver.

Method: In the SAM group, ablation was completed after the first roll-off. In the DAM group, an additional ablation was performed to achieve a second roll-off.

Effects of estradiol and progesterone on tumor necrosis factor alpha-induced apoptosis in human hepatoma HuH-7 cells.

Oxidative stress, including the generation of reactive oxygen species (ROS), is known to be involved in apoptosis. Preventing apoptosis may thereby induce a malignant transformation of liver tumor cells. Estradiol (E2) is a potent endogenous antioxidant.
