Authors: Li T, Han J, Jia L, Hu X, Chen L, Wang Y Abstract A change in the metabolic flux of glucose from mitochondrial oxidative phosphorylation (OXPHOS) to aerobic glycolysis is regarded as one hallmark of cancer. However, the mechanisms underlying the metabolic switch between aerobic glycolysis and OXPHOS are unclear. Here we show that the M2 isoform of pyruvate kinase (PKM2), one of the rate-limiting enzymes in glycolysis, interacts with mitofusin 2 (MFN2), a key regulator of mitochondrial fusion, to promote mitochondrial fusion and OXPHOS, and attenuate glycolysis. mTOR increases the PKM2:MFN2 interaction by p...

Conclusions: Lifetime cannabis use is associated with better working memory and processing speed and worse real-world functioning in the area of socially useful activities in patients with schizophrenia-related disorders. Clinicians should, therefore, be aware of it to provide patient-centred care in their daily clinical practice.Eur Addict Res 2019;25:111 –118

Publication date: June 2019Source: Nano Energy, Volume 60Author(s): Yanfen Wen, Jingjing Fan, Chenguang Shi, Peng Dai, Yuhao Hong, Ruixiang Wang, Lina Wu, Zhiyou Zhou, Juntao Li, Ling Huang, Shi-Gang SunAbstractAs a cost-effective element, Mg has been applied as doped inactive atom to improve the electrochemical performance of sodium-ion cathode materials. Herein, we report Mg-substituted Na0.67Mn0.65Ni0.2Co0.15-xMgxO2 composites as high-performance cathode for sodium-ion batteries and investigate the underlying working mechanism using in situ investigation techniques to monitor the operando changes of electrodes. In situ ...

In this study, several cerasome-forming lipoamino acids (CFLA) were synthesized and used as structural blocks for cerasome preparation. Pure cerasomes which contained only CFLA, and mixed cerasomes based on a mixture of CFLA with a disintegrating dipalmitoylphosphatidylcholine (DPPC) lipid were fabricated and characterized in terms of morphology, mean size, ζ-potential, stability at storage. All obtained cerasome samples were found to be much more stable at storage than conventional liposomes (120 and 10 days, respectively). The cerasomes were loaded with doxorubicin (DOX) and tested in vitro using human breast aden...

In this study, a sustaining antifouling membrane was fabricated by constructing polydopamine (PDA) micro-/nano-spheres on a polyacrylonitrile (PAN) nanofibrous membrane. The secondary PDA nano-spheres not only strengthened the bonding of primary micro-spheres with the substrate, but also diversified the hierarchical structure and chemistry. The composite showed enhanced superhydrophilicity and underwater superoleophobicity. Permeability of PAN-PDAc membrane was maintained as high as 11666 ± 978 Lm−2h−1bar−1 with separation efficiency of higher than 99.9% over a 2-h continuous filtration. This...

Taxol is a common chemotherapy (CTX) drug that is associated with the development of neuropathy. Paclitaxel-induced peripheral neuropathy (PIPN) is the dose limiting toxicity of this CTX drug. Paclitaxel exerts its therapeutic effect by binding to β-tubulin, which interferes with microtubule dynamics and results in microtubule stabilization, mitotic arrest, and apoptosis of cancer cells. However, microtubules are critical for axonal function and for the transport of essential organelles to distal nerve endings.

The objectives of this work were to study 1) effects of oxaliplatin on membrane excitability in Isoletcin B4-positive and –negative (IB4+ and IB4-) subpopulations of dorsal root ganglion (DRG), and 2) targeting oxaliplatin-induced membrane hyperexcitability to relief neuropathic pain.

Patients with cancer are at an increased risk of suicide in the first year after diagnosis compared with the general population,according to areport in the journalCancer. The risk differs by type of cancer, with pancreatic and lung cancer having the highest risk.“After the diagnosis, it is important that health care providers be vigilant in screening for suicide and ensuring that patients have access to social and emotional support,” wrote Anas M. Saad, M.D., of Ain Shams University, Cairo, and colleagues.Using data from the Surveillance, Epidemiology, and End Results (SEER) Program, the researchers calculated ...

In this study we demonstrate the use of clustered regularly interspaced short palindromic repeats (CRISPR)-based epigenome editing to alter cell response to inflammatory environments by repressing inflammatory cytokine cell receptors, specifically TNFR1 and IL1R1. This has applications for many inflammatory-driven diseases. It could be applied for arthritis or to therapeutic cells that are being delivered to inflammatory environments that need to be protected from inflammation." In chronic back pain, for example, slipped or herniated discs are a result of damaged tissue when inflammation causes cells to create ...
