Iron regulatory protein 1 (IRP1) belongs to a family of RNA binding proteins that modulate metazoan iron metabolism. Multiple mechanisms are employed to control the action of IRP1 in dictating changes in the uptake and metabolic fate of iron. Inactivation of IRP1 RNA binding by iron primarily involves insertion of a [4Fe-4S] cluster by the cytosolic iron sulfur cluster assembly (CIA) system converting it into cytosolic aconitase (c-acon) but can also involve iron-mediated degradation of IRP1 by the E3 ligase FBXL5 that also targets IRP2...

Aconiti kusnezoffii radix (AKR), the root of Aconitum kusnezoffii Reichb., is commonly used in the treatment of the rheumatoid arthritis. However, the clinical application is limited due to its potential toxicity. Therefore, to investigate the mechanism of its potential neurotoxicity and nephrotoxicity, a comprehensive metabolomics study combined with serum biochemistry and histopathology measurements was carried out. A UHPLC-Q-TOF mass spectrometry based metabolomics approach was applied to characterize the AKR toxicity, while the toxicity attenuation effects of Aconiti kusnezoffii radix cocta (AKRC) on Wistar rats were also investigated...

Aconiti Lateralis Radix Praeparata ("Fuzi" in Chinese) in combination with Zingiberis Rhizoma ("Ganjiang" in Chinese) is commonly applied for the treatment of heart failure for thousands of years in China. However, its therapeutic mechanism is still poorly defined. This study aimed to investigate whether the compatibility of Fuzi and Ganjiang can protect rats with acute heart failure by enhancing mitochondrial biogenesis via Sirt1/PGC-1α signaling pathway. Hemodynamic parameters, including heart rate and left ventricular maximal rate of pressure rise and decline, were recorded in rats with acute heart failure induced by Propafenone hydrochloride...

BACKGROUND: General practitioners (GPs) play a key role in the care of somatic and psychiatric problems in people diagnosed with schizophrenia (PWS). It is probable that, like other health professionals, GPs are not all free of prejudices toward PWS. In clinical practice, GPs sometimes interact with clients diagnosed with schizophrenia by specialists, passively accepting this diagnosis. Other times, GPs interact with clients having symptoms of schizophrenia but who have not been diagnosed...

Gay and bisexual men (GBM) report higher rates of methamphetamine use compared to heterosexual men, and thus have a heightened risk of developing problems from their use. We examined treatment outcomes among GBM clients receiving outpatient counseling at a lesbian, gay, bisexual, transgender and intersex (LGBTI)-specific, harm reduction treatment service in Sydney, Australia. GBM receiving treatment for methamphetamine use from ACON's Substance Support Service between 2012-15 (n = 101) were interviewed at treatment commencement, and after 4 sessions (n = 60; follow-up 1) and 8 sessions (n = 32; follow-up 2)...

BACKGROUND: Oxaliplatin, a widely used anticancer drug against metastatic colorectal cancer, can induce acute peripheral neuropathy, which is characterized by cold and mechanical allodynia. Activation of glial cells (e.g. astrocytes and microglia) and increase of pro-inflammatory cytokines (e.g. IL-1β and TNF-α) in the spinal cord play a crucial role in the pathogenesis of neuropathic pain. Our previous study demonstrated that Gyejigachulbu-Tang (GBT), a herbal complex formula, alleviates oxaliplatin-induced neuropathic pain in rats by suppressing spinal glial activation...

A method was developed to quantify the performance of microorganisms involved in different digestion levels in biogas plants. The test system was based on the addition of butyrate (BCON), ethanol (ECON), acetate (ACON) or propionate (PCON) to biogas sludge samples and the subsequent analysis of CH4 formation in comparison to control samples. The combination of the four values was referred to as BEAP profile. Determination of BEAP profiles enabled rapid testing of a biogas plant's metabolic state within 24 h and an accurate mapping of all degradation levels in a lab-scale experimental setup...
