Fibromyalgia syndrome (FS) is a chronic painful condition with sensory, motor and affective dysfunctions. Few studies had investigated the trigeminal area, and little is known about its association with hemisensory syndrome, which is characterized by chronic pain restricted to hemibody. Our objective was to investigate sensorial abnormalities with quantitative sensory ...

The HIV-1 viral infectivity factor (VIF) protein is essential for viral replication. VIF recruits cellular ElonginB/C-Cullin5 E3 ubiquitin ligase to target the host antiviral protein APOBEC3G (A3G) for proteasomal degradation. Thus, the A3G-Vif-E3 complex represents an attractive target for the development of novel anti-HIV drugs. In this study, we describe ...

BACKGROUND: Most targeted anticancer therapies, as well as cytotoxic and radiation therapies, are encumbered by the development of secondary resistance by cancer cells. Resistance is a complex phenomenon involving multiple mechanisms, including activation of signaling pathways such as phosphatidylinositol 3-kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR). Novel strategies to overcome resistance ...

Angiostrongyliasis, also known as eosinophils meningitis, is caused by Angiostrongylus cantonensis parasites in the human central nervous system. Currently, the drug of choice for treatment of angiostrongyliasis is albendazole, but dead worm lysis causes severe inflammatory response, which leads to central nervous system damage. Tribendimidine, a broad-spectrum anti-helmintic drug developed ...

The exosome is the major 3'-5' RNA-degradation complex in eukaryotes. The ubiquitous core of the yeast exosome (Exo-10) is formed by nine catalytically inert subunits (Exo-9) and a single active RNase, Rrp44. In the nucleus, the Exo-10 core recruits another nuclease, Rrp6. Here we crystallized an approximately 440-kilodalton complex of ...

Microorganisms produce and secrete secondary metabolites to assist in their survival. We report that the gold resident bacterium Delftia acidovorans produces a secondary metabolite that protects from soluble gold through the generation of solid gold forms. This finding is the first demonstration that a secreted metabolite can protect against toxic ...

Terminally differentiated cells can be reprogrammed to pluripotency by the forced expression of Oct4, Sox2, Klf4 and c-Myc. However, it remains unknown how this leads to the multitude of epigenetic changes observed during the reprogramming process. Interestingly, Oct4 is the only factor that cannot be replaced by other members of ...

The emergence and spread of vancomycin resistance among staphylococci, although rarely described in Japan to date, are major clinical concerns. We describe a case of central venous catheter-associated bloodstream infection in which Staphylococcus epidermidis intermediately resistant to vancomycin (minimum inhibitory concentration, 8 μg/ml) was isolated. The patient fully recovered with removal ...

Percutaneous transluminal angioplasty (PTA) with stenting is widely used in the treatment of vascular disorders but restenosis remains a significant problem. Drug-eluting stents (DES) have been developed as an attempt to reduce the intimal response leading to restenosis. Drugs used in DES include mainly immunosuppressive and anti-proliferative compounds. Glucocorticoids are ...

Trim24 (Tif1α) and Trim33 (Tif1γ) interact to form a co-repressor complex that suppresses murine hepatocellular carcinoma. Here we show that Trim24 and Trim33 cooperatively repress retinoic acid receptor-dependent activity of VL30-class endogenous retroviruses (ERVs) in liver. In Trim24-knockout hepatocytes, VL30 derepression leads to accumulation of reverse-transcribed VL30 cDNA in the ...
