Exosomes participate in cancer progression and metastasis by transferring bioactive molecules between cancer and varied cells in the local and distant microenvironments. Such intercellular cross-talks result in changes in multiple cellular and biological functions in recipient cells. Several hallmarks of cancer have been reportedly impacted by this exosome-mediated cell-to-cell communication, including modulating immune responses, re-programming stromal cells, re-modeling the architecture of extracellular matrix, or even endowing cancer cells with characteristics of drug resistance...

Poor synchrony between the delivery of mechanical breaths, the neural respiratory timing, and needs of patients is relatively frequent under mechanical ventilation in the intensive care unit. This review summarizes the current knowledge on the different types of dyssynchrony described to date, their mechanism, consequences, and potential management. There is still a long way to get to a comprehensive knowledge and uncertainties remain. Ongoing research and development of monitoring tools are urgently needed to allow a better appraisal of this area in a near future...

Two experiments were performed to evaluate the reproductive performance of zebu beef cows treated with different doses of eCG at the end of a progesterone (P4)/estrogen based protocol for timed artificial insemination (TAI). In Experiment 1, suckling Bos indicus Nelore cows (n = 261) received, on day 0, a progesterone (P4) intravaginal device (PD) and an injection of 1 mg estradiol benzoate (EB). On day 8, the PD was removed, 500 μg of cloprostenol was injected, and cows were assigned to one of the following groups: Control (no treatment), 300 (300 IU of eCG), 600 (600 IU of eCG), and 900 (900 IU of eCG)...

Disseminated castration-resistant prostate cancer (CRPC) is a common disease in men that is characterized by limited survival and resistance to androgen-deprivation therapy. The increase in human epidermal growth factor receptor 2 (HER2) signaling contributes to androgen receptor activity in a subset of patients with CRPC; however, enigmatically, HER2-targeted therapies have demonstrated a lack of efficacy in patients with CRPC. Aberrant glycosylation is a hallmark of cancer and involves key processes that support cancer progression...

We previously developed a tissue-engineered vascular graft (TEVG) made by seeding autologous cells onto a biodegradable tubular scaffold, in an attempt to create a living vascular graft with growth potential for use in children undergoing congenital heart surgery. Results of our clinical trial showed that the TEVG possesses growth capacity but that its widespread clinical use is not yet advisable due to the high incidence of TEVG stenosis. In animal models, TEVG stenosis is caused by increased monocytic cell recruitment and its classic ("M1") activation...

Background: Traumatic brain injury (TBI) is known to impact dopamine-mediated reward pathways, but the underlying mechanisms have not been fully established. Methods: Nicotine-induced conditional place preference (CPP) was used to study rats exposed to a 6-psi fluid percussion injury (FPI) with and without prior exposure to nicotine. Preference was quantified as a score defined as (C1-C2) / (C1+C2), where C1 is time in the nicotine-paired compartment and C2 is time in the saline-paired compartment...

BACKGROUND: Complementary integrative health therapies have a perioperative role in the reduction of pain, analgesic use, and anxiety, and increasing patient satisfaction. However, long implementation lags have been quantified. The Consolidated Framework for Implementation Research (CFIR) can help mitigate this translational problem. METHODS: We reviewed evidence for several nonpharmacological treatments (CFIR domain: characteristics of interventions) and studied external context and organizational readiness for change by surveying providers at 11 Veterans Affairs (VA) hospitals (domains: outer and inner settings)...

Ultrafiltration-level polyacrylonitrile (PAN) flat sheet membranes were chemically modified via cross-linking and hydrolysis to provide a suitable surface for the growth of a selective layer composed of Zn-benzene-1,4-dicarboxylic acid (Zn(BDC)) metal-organic framework (MOF). Unlike typical membrane modification methods or conventional MOF synthesis procedures, deionized (DI) water was the only solvent used for each of the modification steps involved. To better understand the layer-by-layer MOF growth, several MOF growth conditions were also studied, including the effects of solution concentration, growth temperature, membrane immersion time and the number of layers...

Cell-in-cell (CIC) structures, characterized by enclosure of one or more cells within another cell, were extensively documented in human cancers. Although elevated CIC formation was found in cancers with CDKN2A inactivation, a causal link between them remains to be established. We reported here that inhibiting CDKN2A expression effectively promoted homotypic CIC formation, whereas ectopic overexpression of p16INK4a or p14ARF, two proteins encoded by CDKN2A gene, significantly suppressed CIC formation in MCF7 cells...

Cisplatin (DPP), a clinically potent antineoplastic agent, is limited by its severe adverse effects. The aim of this study was to investigate the effect of oligogalacturonides (OGA) and DDP on human lung cancer A549 cells. The combined use of OGA and DDP had a synergistic effect on the growth inhibition of A549 cells, changed the cell cycle distribution, and enhanced apoptotic response, especially in sequential combination treatment group of DDP 12 h + OGA 12 h. Western blot analyses showed that the combination treatment of OGA and DDP upregulated Bax, p53, and Caspase-3 and downregulated Bcl-2 proteins...

MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression. Emerging evidence has suggested a role for miRNAs in the development of diabetic kidney disease (DKD), indicating that miRNAs may represent potential biomarkers of this disease. However, results are still inconclusive. Therefore, we performed a systematic review of the literature on the subject, followed by bioinformatic analysis. PubMed and EMBASE were searched to identify all studies that compared miRNA expressions between patients with DKD and diabetic patients without this complication or healthy subjects...

ortho-Methyl effects are exploited to tune steric hindrance between side-chain N,N´-diaryls and polycyclic dihydrodibenzo[a,c]phenazine, and in turn control the conformations of N,N´-diphenyl-dihydrodibenzo[a,c]phenazine (DPAC) and its ortho-methyl(s) derivatives Mx-My (x = 0, 1 or 2, y = 1 or 2, x and y correlate with the number of methyl groups in the ortho-sites of N,N´-diphenyl). The magnitude of steric hindrance increases as x and y increase, and the V-shaped dihydrodibenzo[a,c]phenazine skeleton is gradually tuned from bent (DPAC) to planar (M2-M2) structure in the ground state...

New heteroleptic Ru(ii) complexes consisting of pyridylimine as an ancillary ligand were synthesized and characterized for applications in dye sensitized solar cells. Complexes with cis and trans configurations around the central ruthenium metal were obtained using simple synthetic protocols by varying the substituents on the pyridylimine ligands. The geometries of these complexes were confirmed by single crystal X-ray analysis. The effect of the difference in the configurations of these complexes on their device performances was studied and the sensitizer with a trans arrangement around the metal showed a higher overall conversion efficiency (η) of 7...
