BACKGROUND: Renal dysfunction is recognized with increasing frequency among the noninfectious comorbidities associated with human immunodeficiency virus (HIV) infection. Urinary liver-type fatty acid-binding protein (L-FABP) has been shown to be a new biomarker to screen for not only tubulointerstitial damage but also kidney dysfunction. METHODS: We performed a cross-sectional study to determine the association between the urinary L-FABP and chronic kidney disease (CKD) among 77 HIV-infected Japanese patients by backward-stepwise multivariable logistic regression...

We report the case of a 55-year-old man with stage IV lung adenocarcinoma who received carboplatin-paclitaxel-bevacizumab chemotherapy as second-line therapy. After four cycles of chemotherapy, he experienced syncope with a decrease in blood pressure. Electrocardiography (ECG) revealed atrial fibrillation. Cardiac ultrasonography showed a markedly reduced ejection fraction (45%), with moderate decrease in comparison to that before chemotherapy (66%). Bisoprolol fumarate was initiated, and the conversion to sinus rhythm was detected by ECG 4 days after the syncope...

ETHNOPHARMACOLOGICAL RELEVANCE: Fuzi, the processed lateral root of Aconitum carmichaelii Debeaux, is a traditional Chinese medicine used for its analgesic, antipyretic, anti-rheumatoid arthritis and anti-inflammation effects; however, it is also well known for its toxicity. Gancao, the root of Glycyrrhiza uralensis Fisch., is often used concurrently with Fuzi to alleviate its toxicity. However, the mechanism of detoxication is still not well clear. AIM OF THE STUDY: In this study, the effect of Gancao on the metabolic changes induced by Fuzi was investigated by NMR-based metabonomic approaches...

Dimethyl fumarate (DMF), the methyl ester form of fumaric acid (DMF) is an effective mold-growth inhibitor. It has a wide-spectrum biocide activity and has been used to protect leather during storage and transport. DMF was first identified as a potent contact sensitizer during a contact dermatitis outbreak that occurred because of its use in Chinese manufactured furniture (1,2).

To judge the developability and analyze functional mechanism of co-amorphouses, we investigated the physicochemical properties of co-amorphouses and compare the properties with the co-crystals having the same drug and counters. Co-amorphous compounds are a novel approach to improve the physicochemical properties of drugs. A co-amorphous is in an amorphous solid state allowing non-ionic interactions between drug molecules and counter molecules. The co-amorphous compounds composed of itraconazole (ITZ) with the organic carboxyl acid, fumaric acid (FA) or L-tartaric acid (TA), were prepared by mechanical grinding...

BACKGROUND: Dimethyl fumarate (DMF), working via its metabolite monomethylfumarate (MMF), acts as a potent antioxidant and immunomodulator in animal models of neurologic disease and in patients with multiple sclerosis. These properties and their translational potential led us to investigate whether DMF/MMF could also protect at-risk and/or dying neurons in models of ischemic stroke in vitro and in vivo. Although the antioxidant effects have been partially addressed, the benefits of DMF immunomodulation after ischemic stroke still need to be explored...

Objective Delayed-release dimethyl fumarate (DMF; also known as gastro-resistant DMF) and fingolimod are approved oral disease-modifying treatments for relapsing-remitting multiple sclerosis. In phase 3 trials, DMF (DEFINE/CONFIRM) and fingolimod (FREEDOMS/FREEDOMS II) resulted in significant reductions in clinical and magnetic resonance imaging activity, with acceptable safety profiles. Direct comparisons of these treatments are not possible due to a lack of head-to-head trials. We compared 2-year efficacy of DMF versus fingolimod at the approved dosage using a matching-adjusted indirect approach...

Mutations to the Krebs cycle enzyme fumarate hydratase in cancer cells leads to an accumulation of the oncometabolite fumarate. Sciacovelli et al. (2016) demonstrate an epigenetically dependent epithelial-to-mesenchymal transition mediated by modulation of the miR-200 cluster and TET demethylation in response to fumarate accumulation.

Delayed-release dimethyl fumarate (DMF) is an approved treatment for multiple sclerosis (MS). Microglia are considered central to MS pathophysiology, however the effects of DMF and the primary metabolite monomethyl fumarate (MMF) on microglia are not well characterized. We demonstrated that DMF and MMF altered transcriptional responses in primary microglia related to the nuclear factor (erythroid-derived 2)-like 2 pathway. Additionally, through an NRF2 independent manner, DMF, but not MMF significantly reduced production of proinflammatory mediators in classically activated microglia, and further rescued mitochondrial respiratory deficits in primary cortical neurons that were induced by activated microglia...

It has been reported that tumor growth and proliferation correspond to mitochondrial dysfunction and that the tumor cellular microenvironment plays a key role in tumor progression, representing an area that might be manipulated to confer therapeutic anti-tumor benefits. In this article, we have identified mitochondrial genes, largely nuclear-encoded genes, which are differentially expressed in breast cancer epithelial and stromal cells compared to cells from normal breast tissues. We determined that gene expression of the mitochondrial membrane respiratory chain complex I and IV and ATP synthesis were reduced in both in epithelial and stromal cancer cells compared to normal breast cells...

Geobacter sulfurreducens is a dissimilatory metal-reducing bacterium capable of forming thick electron-conducting biofilms on solid electrodes. Here, we employ for the first time comparative proteomics to identify key physiological changes involved in G. sulfurreducens adaptation from fumarate-respiring planktonic cells to electron-conducting biofilms. Increased levels of proteins involved in outer membrane biogenesis, cell motility and secretion are expressed in biofilms. Of particular importance to the electron-conducting biofilms are proteins associated with secretion systems of Type I, II, V and Type IV pili...
