Bleeding complications associated with the molecular adsorbent recirculating system: a retrospective study.

Background: The molecular adsorbent recirculating system (MARS) is a hepatic replacement system that supports excretory liver function in patients with liver failure. However, since MARS has been employed in our hospital, bleeding complications have occurred in many patients during or after MARS. The objective of this study was to determine how MARS affects coagulopathy and identify specific factors associated with bleeding complications.

Comparison between surgery and radiofrequency ablation for stage I non-small cell lung cancer.

Surgical resection remains as the treatment of choice for non-small cell lung cancer (NSCLC) and provides the best opportunity for cure and long-term survival. Minimally invasive percutaneous ablative therapies, such as radiofrequency ablation (RFA) for treating lung cancers, are currently being studied as treatment alternatives. But, to date, there is little information on comparison of therapeutic effects between surgery and RFA in patients with early stage lung malignancy.

Treatment of asymptomatic pulmonary cryptococcosis in immunocompetent hosts with oral fluconazole.

Background: Pulmonary cryptococcosis is occasionally detected on routine imaging studies in healthy hosts with no or mild symptoms. Isolated pulmonary cryptococcosis may be observed without specific therapy in asymptomatic immunocompetent hosts. However, considering that dissemination from a pulmonary infection can occur in patients with no immunologic defects, treatment of asymptomatic pulmonary cryptococcosis in immunocompetent hosts remains controversial.

Clinical usefulness of D2-40 in non-small cell lung cancer.

D2-40 is a recently developed monoclonal antibody that reacts with a 40 kDa O-linked sialoglycoprotein and has been used for the assessment of lymphatic invasion in tumor specimens. We have evaluated the diagnostic usefulness of D2-40 and association of its immunopositivity with clinicopathological parameters in adenocarcinoma and squamous cell carcinoma of the lung. We investigated 97 cases of surgically resected adenocarcinoma or squamous cell carcinoma of the lung for the determination of D2-40 positivity in tumor cells and peritumoral lymphatic vessel density (LVD) using an immunostaining method.

Pulmonary cryptococcosis in asymptomatic immunocompetent hosts.

Pulmonary cryptococcosis tends to occur commonly in immunocompromized patients. However, as more individuals are undergoing regular medical examinations, the number of cases of pulmonary cryptococcosis detected incidentally in immunocompetent individuals is increasing. The aim of the present study was to evaluate the radiologic manifestations of pulmonary cryptococcosis in immunocompetent patients with no significant symptoms.

A novel thiol compound, N-acetylcysteine amide, attenuates allergic airway disease by regulating activation of NF-kappaB and hypoxia-inducible factor-1alpha.

Reactive oxygen species (ROS) play an important role in the pathogenesis of airway inflammation and hyperresponsiveness. Recent studies have demonstrated that antioxidants are able to reduce airway inflammation and hyperreactivity in animal models of allergic airway disease. A newly developed antioxidant, small molecular weight thiol compound, N-acetylcysteine amide (AD4) has been shown to increase cellular levels of glutathione and to attenuate oxidative stress related disorders such as Alzheimer's disease, Parkinson's disease, and multiple sclerosis.
