Hepatocellular carcinoma (HCC) is the sixth most common cancer. The Warburg effect is an important way by which HCC adapts to a hypoxic environment. The aim of the present study was to determine whether and how galangin reverses the Warburg effect in HCC cells. We treated three HCC cell lines, HepG2, Hep3B and PLC/PRF/5 with galangin for 24h, respectively. Cell proliferation was measured with MTT assay. Glucose uptake, lactate production and the oxygen consumption were measured. Pyruvate kinase activities were detected by measuring the consumption of NADH, and glycolytic pathway-related proteins were measured by Western blotting...

Autologous thrombocyte concentrate lysates as platelet-released growth factors (PRGF) or Vivostat Platelet Rich Fibrin (PRF(®)) represent important tools in modern wound therapy, especially in the treatment of chronic, hard-to-heal or infected wounds. Nevertheless, underlying cellular and molecular mechanisms of the beneficial clinical effects of a local wound therapy with autologous thrombocyte concentrate lysates are poorly understood. Recently, we have demonstrated that PRGF induces antimicrobial peptides in primary keratinocytes and accelerates keratinocytes' differentiation...

Programmed ribosomal frameshifting (PRF) is a translational anomaly causing the ribosome to shift into an alternative reading frame. PRFs are common in viral genomes, using a single nucleotide sequence to code for two proteins in overlapping frames. In bacteria and eukaryota, PRFs are less frequent. We report on a PRF in the copper detoxification system of Escherichia coli where a metallochaperone is generated out of the first 69 amino acids and a C-terminal out-of-frame glycine of the gene copA. copA besides codes for the P1B -ATPase CopA, a membrane-integral protein and principal interaction target of the chaperone...

The study presents the proof of concept for a possibility to achieve a better electroporation in the MHz pulse repetition frequency (PRF) region compared to the conventional low frequency protocols. The 200ns×10 pulses bursts of 10-14kV/cm have been used to permeabilize Chinese hamster ovary (CHO) cells in a wide range (1Hz-1MHz) of PRF. The permeabilization efficiency was evaluated using fluorescent dye assay (propidium iodide) and flow cytometry. It was determined that a threshold PRF exists when the relaxation of the cell transmembrane potential is longer than the delay between the consequent pulses, which results in accumulation of the charge on the membrane...

A goal of computational models is not only to explain experimental data but also to make new predictions. A current focus of computational neuroimaging is to predict features of the presented stimulus from measured brain signals. These computational neuroimaging approaches may be agnostic about the underlying neural processes or may be biologically inspired. Here, we use the biologically inspired population receptive field (pRF) approach to identify presented images from fMRI recordings of the visual cortex, using an explicit model of the underlying neural response selectivity...

We introduce a probabilistic (Bayesian) framework and associated software toolbox for mapping population receptive fields (pRFs) based on fMRI data. This generic approach is intended to work with stimuli of any dimension and is demonstrated and validated in the context of 2D retinotopic mapping. The framework enables the experimenter to specify generative (encoding) models of fMRI timeseries, in which experimental stimuli enter a pRF model of neural activity, which in turns drives a nonlinear model of neurovascular coupling and Blood Oxygenation Level Dependent (BOLD) response...

Our previous studies demonstrated that membrane-associated hepatitis E virus (HEV) particles-now considered "quasi-enveloped particles"-are present in the multivesicular body with intraluminal vesicles (exosomes) in infected cells, and that the release of HEV virions is related to the exosomal pathway. In this study, we characterized exosomes purified from culture supernatant of HEV-infected PLC/PRF/5 cells. Purified CD63-, CD9-, or CD81-positive exosomes derived from the culture supernatant of HEV-infected cells that had been cultivated in serum-free medium were found to contain HEV RNA and the viral capsid (ORF2) and ORF3 proteins, as determined by a RT-PCR and Western blotting, respectively...

Currently, the buccal advancement flap, palatal rotational flap, and buccal fat pad techniques are frequently used to close an oroantral communication (OAC). In this study, platelet-rich fibrin (PRF) clots were used for immediate closure of acute OACs after extraction of posterior maxillary molars. Acute oroantral perforations larger than 3 mm in diameter in 21 patients were treated uneventfully using PRF clots. None of the patients had systemic diseases or symptoms of sinus disease. After tooth extraction, the diagnosis of acute OAC was examined by the Valsalva maneuver (compressing the nostrils with the fingers and then blowing out air)...

BACKGROUND: Although osteochondral autograft transplantation (OAT) provides satisfactory outcomes for osteochondral defects, for large defects OAT is often inadequate because of graft availability. Osteochondral allograft transplantation is an alternative treatment for large defects, but this approach is limited by graft storage constraints and carries disease transmission risks. Platelet-rich fibrin (PRF) is a second-generation platelet concentrate, and its positive effect on articular cartilage has been reported...
