Myofascial Pain.

Semin Neurol 2018 Dec 6;38(6):640-643. Epub 2018 Dec 6.

Department of Neurology, Boston University School of Medicine, Boston, Massachusetts.

Myofascial pain syndromes arise from acute and chronic musculoskeletal pain and often have a referred neuropathic component. It affects more than three quarters of the world's population and is one of the most important and overlooked causes of disability. The origins of pain are thought to reside anywhere between the motor end plate and the fibrous outer covering of the muscle, with involvement of microvasculature and neurotransmitters at the cellular level.

Luteal granulosa cells from natural cycles are more capable of maintaining their viability, steroidogenic activity and LH receptor expression than those of stimulated IVF cycles.

Hum Reprod 2018 Dec 6. Epub 2018 Dec 6.

Graduate School of Health Sciences, Koc University, Davutpasa, Topkapi, Istanbul, Turkey.

Study Question: Are there any differences in the molecular characteristics of the luteal granulosa cells (GC) obtained from stimulated versus non-stimulated (natural) IVF cycles that may help explain the defective luteal phase in the former?

Summary Answer: Luteal GC of stimulated IVF cycles, particularly those of agonist-triggered antagonist cycles, are less viable ex vivo, express LH receptor and anti-apoptotic genes at lower levels, undergo apoptosis earlier and fail to maintain their estradiol (E2) and progesterone (P4) production in comparison to natural cycle GC.

What Is Known Already: Luteal function is defective in stimulated IVF cycles, which necessitates P4 and/or hCG administration (known as luteal phase support) in order to improve clinical pregnancy rates and prevent miscarriage. The luteal phase becomes shorter and menstruation begins earlier than a natural cycle if a pregnancy cannot be achieved, indicative of early demise of corpus luteum (premature luteolysis). Read More

Mechanosensitive (MS) ion channels provide a universal mechanism for sensing and responding to increased membrane tension. MscS-like (MSL) 10 is a relatively well-studied MS ion channel from that is implicated in cell death signaling. The relationship between the amino acid sequence of MSL10 and its conductance, gating tension, and opening and closing kinetics remains unstudied. Read More

Ribosome Profiling Reveals HSP90 Inhibitor Effects on Stage-Specific Protein Synthesis in .

mSystems 2018 Nov-Dec;3(6). Epub 2018 Nov 20.

Leishmaniasis Group, Bernhard Nocht Institute for Tropical Medicine, Hamburg, Germany.

The 90-kDa heat shock protein (HSP90) of eukaryotes is a highly abundant and essential chaperone required for the maturation of regulatory and signal proteins. In the protozoan parasite Leishmania donovani, causative agent of the fatal visceral leishmaniasis, HSP90 activity is essential for cell proliferation and survival. Even more importantly, its inhibition causes life cycle progression from the insect stage to the pathogenic, mammalian stage. Read More

Erythrocyte Aging, Protection via Vesiculation: An Analysis Methodology via Oscillatory Flow.

Front Physiol 2018 16;9:1607. Epub 2018 Nov 16.

Biological Engineering, University of California, San Diego, La Jolla, CA, United States.

We demonstrate that erythrocyte deformations, specifically of a type as occur in splenic flow (Zhu et al., 2017), and of the type that promote vesiculation can be caused by simple, yet tailored, oscillatory shear flow. We show that such oscillatory shear flow provides an ideal environment to explore a wide variety of metabolic and biochemical effects that promote erythrocyte vesiculation. Read More

Excitotoxic superoxide production and neuronal death require both ionotropic and non-ionotropic NMDA receptor signaling.

Sci Rep 2018 Nov 30;8(1):17522. Epub 2018 Nov 30.

Department of Neurology, University of California, San Francisco, San Francisco, CA, 94122, USA.

NMDA-type glutamate receptors (NMDAR) trigger superoxide production by neuronal NADPH oxidase-2 (NOX2), which if sustained leads to cell death. This process involves Ca influx through NMDAR channels. By contrast, comparable Ca influx by other routes does not induce NOX2 activation or cell death. Read More

Plasma redox imbalance caused by albumin oxidation promotes lung-predominant NETosis and pulmonary cancer metastasis.

Nat Commun 2018 Nov 30;9(1):5116. Epub 2018 Nov 30.

Princess Margaret Cancer Centre Research Institute, University Health Network, Toronto, M5G2M9, ON, Canada.

Neutrophil extracellular traps (NETs) promote cancer metastasis in preclinical models following massive exogenous inflammatory stimuli. It remains unknown whether cancer hosts under physiologic conditions experience NETosis and consequent metastasis. Here we show that plasma redox imbalance caused by albumin oxidation promotes inflammation-independent NETosis. Read More

Paradoxical, causal effects of sensory gain modulation on motor inhibitory control - a tDCS, EEG-source localization study.

Sci Rep 2018 Nov 30;8(1):17486. Epub 2018 Nov 30.

Cognitive Neurophysiology, Department of Child and Adolescent Psychiatry, Faculty of Medicine, TU Dresden, Germany.

Response inhibition is a key component of executive functioning, but the role of perceptual processes has only recently been focused. Although the interrelation of incoming information and resulting behavioural (motor) effects is well-known to depend on gain control mechanisms, the causal role of sensory gain modulation for response inhibition is elusive. We investigate it using a somatosensory response inhibition (Go/Nogo) task and examine the effects of parietal (somatosensory) cathodal and sham tDCS stimulation on a behavioural and neurophysiological level.

Dissymmetry enhancement in enantioselective synthesis of helical polydiacetylene by application of superchiral light.

Nat Commun 2018 Nov 30;9(1):5117. Epub 2018 Nov 30.

CAS Key Laboratory of Soft Matter Chemistry, Department of Polymer Science and Engineering, iChEM, University of Science and Technology of China, 230026, Hefei, Anhui, China.

Superchiral light, generated by the interference of two counter-propagating circularly polarized light (CPL) with same frequency, opposite handedness and different intensity, exhibits enhanced dissymmetry in its interaction with chiral molecules, and has the potential for ultrasensitive detection and characterization of chiral molecules. It is anticipated that the enhanced optical dissymmetry in superchiral light (SCL) field may be utilized to promote asymmetric photochemical reactions efficiency. Herein we reported SCL impart greater chiral bias to trigger asymmetric photo-polymerization reaction from initially achiral diacetylene (DA) monomer, and the enhanced optical dissymmetry for whole polydiacetylene (PDA) films could be achieved.
