IL-1β-stimulated rat hepatocytes are a newly identified source of TNF-α in the liver. TNF-α mRNA and asRNA are expressed in rats and humans, and the TNF-α asRNA reduces the stability of the TNF-α mRNA. Hepatocytes and TNF-α asRNA may be therapeutic targets to regulate levels of TNF-α mRNA.
Objectives: To evaluate the efficacy and toxicity profiles of everolimus in Japanese patients with renal angiomyolipoma associated with tuberous sclerosis complex. Methods: Patients with a 4-cm or larger angiomyolipoma meeting the diagnostic criteria of tuberous sclerosis complex were selected as participants of our investigation. In each case, we assessed tuberous sclerosis complex-associated symptoms, the treatment effect and adverse events. The treatment effect was evaluated by measuring the tumor volume reduction rate using abdominal computed tomography or magneitc resonance imaging. Adverse events were investigated using CTCAE v4.0-JCOG. The dose of everolimus was set at 10 mg once a day for adults. For childhood angiomyolipoma, everolimus administration was initiated at a dose of 5 mg once a day. Blood everolimus level was measured, and the dose was adjusted to maintain this within a range of 5-15 ng/mL. Results: The angiomyolipoma volume decreased in 46 of 47 cases, and the mean reduction rate for all cases was 60% in 12 months. The angiomyolipoma volume markedly decreased in the first 3 months, and the size leveled off after 6 months. The main adverse events related to everolimus treatment were stomatitis (91%) and irregular menstruation (65%). Grade 3 or severer adverse events were noted in three cases (6%). All patients developed some adverse events in the first 6 months. The incidence markedly decreased to 40-50% after 13 months. Conclusion: The tumor volume-reducing effect of everolimus in a Japanese population was equivalent to or higher than that in Western populations. A wide variety of everolimus treatment-related adverse events can be observed, but most cases are very mild. Special attention should be given to stomatitis, irregular menstruation and interstitial lung disease as adverse events.
Fecal bacteria in Hokkaido native horses were enumerated by their morphology and Gram staining, and then three major cellulolytic species were quantitated by recently developed competitive polymerase chain reaction (cPCR) assays. Fecal bacterial flora in horses showed drastic change between grazing on summer grassland pasture and grazing on winter woodland pasture mainly consisting of bamboo grass (Sasa nipponica). The number of total bacteria was decreased in winter samples, accompanied with a higher proportion of Gram negative rods and lower proportions of Gram negative cocci, Gram positive rods and cocci than those in summer. This high proportion of Gram negative rods was partly explained by the high cPCR-assay values for Fibrobacter succinogenes (a highly cellulolytic Gram negative rod) in winter samples. Of three major cellulolytic bacterial species, F. succinogenes was dominant in feces of
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
