Electron and nuclear pressures in electron-nucleus mixtures

open access: yes, 2007
It is shown for an electron-nucleus mixture that the electron and nuclear pressures are defined clearly and simply by the virial theorem; the total pressure of this system is a sum of these two pressures.

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Metformin promotes mitochondrial integrity through AMPK‐signaling in Leber's hereditary optic neuropathy

open access: yesFEBS Open Bio, EarlyView.
Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...

Evaluation of in vitro toxicity of common phytochemicals included in weight loss supplements using 1H NMR spectroscopy

open access: yesFEBS Open Bio, EarlyView.
We investigated the toxicity of 12 active compounds commonly found in herbal weight loss supplements (WLS) using human liver and colon cell models. Epigallocatechin‐3‐gallate was the only compound showing significant toxicity. Metabolic profiling revealed protein degradation, disrupted energy and lipid metabolism suggesting that the inclusion of EGCG ...

Monte Carlo study of medium-energy electron penetration in aluminium and silver

open access: yesNukleonika, 2015
Monte Carlo simulations are very useful for many physical processes. The transport of particles was simulated by Monte Carlo calculating the basic parameters such as probabilities of transmitted–reflected and angular-energy distributions after ...

Pioglitazone plus (−)‐epigallocatechin gallate: a novel approach to enhance osteogenic performance in aged bone marrow mesenchymal stem cells

open access: yesFEBS Open Bio, EarlyView.
Aged human bmMSCs are seeded in the scaffold. Osteoblastic induction can slightly increase cell's bone‐forming activity to produce bone‐like tissues, shown as the sporadic xylenol orange‐stained spots (the lower left image). Notably, pioglitazone plus EGCG co‐treatment dramatically increases cell's bone‐forming activity and bone‐like tissue production (

Relaxation of high-energy quasiparticle distributions: electron-electron scattering in a two-dimensional electron gas

open access: yes, 2003
A theory is developed for the evolution of the non-equilibrium distribution of quasiparticles when the scattering rate decreases due to particle collisions.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Clinical observation of monoclonal fibrillary glomerulonephritis

open access: yesВестник медицинского института «Реавиз»: Реабилитация, врач и здоровье
Monoclonal gammopathy of renal significance is a condition caused by the proliferation of a clone of B-lymphocytes or plasma cells that does not reach the criteria required for the initiation of treatment for oncohematological indications, but is ...

ДОСЛІДЖЕННЯ ВПЛИВУ ХАОТИЧНОГО СТРУМУ ЕЛЕКТРОНІВ НА ПАРАМЕТРИ ЕЛЕКТРИЧНОГО ПОЛЯ У ПРИАНОДНІЙ ЗОНІ РОЗРЯДУ

open access: yesElektrotehnìka ta Elektroenergetika, 2010
Розглянуто вплив співвідношення густини розрядного та хаотичного електронних струмів на падіння потенціалу у дифузійній зоні прианодної області. Виконано аналіз впливу вимушеної конвекції на умови існування стійкого дифузного розряду на поверхні анода.
