A standardized assessment of BM fibrosis with differentiation between reticulin, collagen and osteosclerosis is recommended to evaluate the various components of the fibrous matrix which may be delinked after therapy. In this regard, quality of staining and application of laboratory standards enable a highly reproducible scoring.

In March 2014, Ebola virus (EBOV) was identified as the causative agent. This study compares the pathogenesis of a new EBOV strain, Makona, which was isolated in Guinea in 2014 with the prototype strain from the 1976 EBOV outbreak in the former Zaire. Both strains cause lethal disease in cynomolgus macaques with similar pathologic changes and hallmark features of Ebola hemorrhagic fever. However, disease progression was delayed in EBOV-Makona-infected animals, suggesting decreased rather than increased virulence of this most recent EBOV strain.
The UK prevalence of abdominal aortic aneurysm (AAA) is estimated at 4.9% in over 65-year olds. Progressive and unpredictable enlargement can lead to rupture. Endovascular repair of AAAs involves a stent graft system being introduced via the femoral artery and manipulated within the aorta under radiological guidance. Following endograft deployment, a seal is formed at the proximal and distal landing zones to exclude the aneurysm sac from the circulation. With the increasing popularity of endovascular repair there has been an increase in the number of commercially available stent graft designs on the market. This is an update of the review first published in 2013.

This review aimed to assess the different stent graft types for endovascular repair of AAA.

The Cochrane Vascular Group Trials Search Co-ordinator (TSC) searched the Specialised Register (last searched February 2015) and the Cochrane Register of Studies (2015, Issue 1). Trial databases were searched by the TSC for details of ongoing and unpublished studies.

All published and unpublished randomised controlled trials (RCTs) of stent graft types in the repair of AAAs were sought without language restriction and in consultation with the Cochrane Vascular Group TSC.

We planned to conduct data collection and analysis in accordance with the Cochrane Handbook for Systematic Reviews of Interventions.

No studies were identified that met the inclusion criteria. It was not possible to review the quality of the evidence in the absence of studies eligible for inclusion in the review.

Unfortunately, no data exist regarding direct comparisons of the performance of different stent graft types. High quality randomised controlled trials evaluating stent graft types in abdominal endovascular aneurysm repair are required.

We previously identified and characterized a novel member of the Peroxiredoxin (PRX) like 2 family that we called PAMM Peroxiredoxin Activated in M-CSF stimulated Monocytes, a redox regulatory protein that modulates osteoclast differentiation in vitro. In this study, we report increased PAMM expression in H2O2-treated cells and in bones from ovariectomized (OVX) mice 4 weeks after surgery, models for oxidative stress in vitro and in vivo, respectively. We also detected increased PAMM abundance and phosphorylated Akt in OVX mice treated with estrogen. In addition, Wortmannin, a specific PI3Kinase inhibitor and Rapamycin, an inhibitor of the PI3Kinase/Akt pathway, blocked Akt phosphorylation and stimulation of PAMM expression by M-CSF. These results indicate that M-CSF-induced PAMM expression is mediated by Akt phosphorylation. Our data also suggest that estrogen-induced PAMM expression is mediated by phosphorylation of Akt. These findings point to PAMM as a potential candidate for Akt-mediated protection against oxidative stress.
Nonthyroidal illness syndrome (NTIS) is marked by low T3 and high reverse T3 levels. The physiopathology is poorly understood but involves oxidative stress-induced disruption of the iodothyronine deiodinases, which activate or inactivate thyroid hormones. Selenium, an essential trace element, exerts antioxidant function mainly through the thioredoxin reductase (TRx) and glutathione peroxidase (GPx) redox-regulating systems. Selleck SHP099 We evaluated the effect of sodium selenite on IL6-induced disruption on deiodinase function. Cell lines expressing endogenous deiodinases type 1(D1), 2(D2) or 3(D3) (HepG2, MSTO, and MCF-7 cells, respectively) were used in an intact cell model that mimics the deiodination process under physiological conditions of substrate and cofactor, in the presence or not of IL6, with or without selenite. Deiodinase activity was quantified by the amount of iodine-125 in the medium (D1 and D2) or by ion-exchange chromatography (D3). Oxidative stress was evaluated by measuring reactive species (RS), caROS and carbonyl content, while enhances Gpx and Trx activities. Nevertheless, it failed on restoring D1 or D2 function and only attenuates D3 activation (P less then 0.05). In conclusion, although sodium selenite reduces IL6-induced redox imbalance it does not fully repair deiodinase function. These results shed light on NTIS physiopathology and might explain why low T3 levels are unaffected by selenium supplementation in sick patients.We present the first coordination-induced spin-state switching with nickel chlorin and nickel isobacteriochlorin. link2 The spin-state switching was monitored by UV-vis spectroscopy and NMR titration experiments. The association constants (K1 and K2) and thermodynamic parameters (ΔH and ΔS) of the coordination of pyridine were determined. The first X-ray analyses of a paramagnetic nickel chlorin and a nickel isobacteriochlorin provide further information about the structure of the octahedral complexes. Nickel chlorin and even more pronounced nickel isobacteriochlorin exhibit stronger coordination of axial ligands compared to the corresponding nickel porphyrin and thus provide the basis for more efficient spin-switching systems.
Precise delineation of the specific genes and pathways altered with aging and estrogen (E) therapy may lead to new skeletal biomarkers and the development of novel bone therapeutics. Previous human bone studies, however, have been limited by only examining pre-specified genes and pathways. High-throughput RNA sequencing (RNAseq), on the other hand, offers an unbiased approach to examine the entire transcriptome. Here we present an RNAseq analysis of human bone samples, obtained from iliac crest needle biopsies, to yield the first in vivo interrogation of all genes and pathways that may be altered in bone with aging and E therapy in humans. 58 healthy women were studied, including 19 young women (mean age ± SD, 30.3 ± 5.4 years), 19 old women (73.1 ± 6.6 years), and 20 old women treated with 3 weeks of E therapy (70.5 ± 5.2 years). link3 Using generally accepted criteria (false discovery rate [q] < 0.10), aging altered a total of 678 genes and 12 pathways, including a subset known to regulate bone metabolism (eghlight potential pathways that could be targeted to treat osteoporosis.

IL-13 is a T-helper cell type 2 cytokine that plays an important role in the pathogenesis of asthma. IL-13 exposure for 14 days transforms cultured normal human bronchial epithelial cells to a goblet cell phenotype. We hypothesized that goblet cells would have a different pattern of cytokine secretion than ciliated airway cells.

Normal human bronchial epithelial cells were grown for 14 days at an air-liquid interface with IL-13 to produce a goblet cell phenotype (n = 4) or with phosphate-buffered saline to produce ciliated cells (n = 4). Ciliated cells were also acutely exposed to IL-13 for 24 h (n = 4). Apical (air side) and basolateral medium was collected, and a multiplex immunoassay of 27 cytokines and inflammatory mediators was performed. The pattern of mediator secretion was then compared.

The goblet cell phenotype secreted greater amounts of proinflammatory cytokines and mediators than ciliated cells and, for the most part, apical secretion was greater than secretion into the basolateral medium. Apical IL-4, IL-5 (P < .0033), and IL-9 (P < .001) and basolateral IL-9, IL-13 (P < .0001), eotaxin, IL-17 (P < .0033), basic fibroblast growth factor (P < .001), and vascular endothelial growth factor (P < .0001) were secreted in greater amounts from goblet cells than from ciliated cells. IL-8 was secreted in higher concentration in both apical (P < .0001) and basolateral (P < .0033) compartments from the goblet cells. Ciliated cells exposed to IL-13 for just 24 h had modestly increased apical IL-8 secretions (P < .0033), but there was no increase in other cytokines.

Inflammatory mediators released from goblet cells may act in an autocrine and paracrine manner to enhance inflammation in diseases such as asthma in which there is increased IL-13 and goblet cell hyperplasia.

Gold nanoparticles (AuNP; 30 nm) were modified with polyethylene glycol (PEG) chains (4 kDa) derivatized with 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) chelators for complexing the β-emitter, (177)Lu and with PEG chains (5 kDa) linked to panitumumab for targeting BC cells expressing EGFR. The AuNP were further coated with PEG chains (2 kDa) to stabilize the particles to aggregation. The binding and internalization of EGFR-targeted AuNP ((177)Lu-T-AuNP) into BC cells was studied and compared to nontargeted (177)Lu-NT-AuNP. The cytotoxicity of (177)Lu-T-AuNP and (177)Lu-NT-AuNP was measured in clonogenic assays using BC cells with widely different EGFR densities MDA-MB-468 (10(6) receptors/cell), MDA-MB-231 (10(5) receptors/cell), and MCF-7 cells (10(4) receptors/cell). Radiation absorbed doses to nd 25.8 ± 1.2%, respectively). Because the β-particles emitted by (177)Lu have a 2 mm range, (177)Lu-NT-AuNP were also cytotoxic to BC cells due to a cross-fire effect but (177)Lu-T-AuNP were significantly more potent for killing MDA-MB-468 cells overexpressing EGFR than (177)Lu-NT-AuNP at all amounts tested. The cross-fire effect of the β-particles emitted by (177)Lu may be valuable for eradicating BC cells in tumors that have low or moderate EGFR expression or cells that are not targeted by (177)Lu-T-AuNP as a consequence of heterogeneous intratumoral distribution. The radiation dose to the nucleus of a single MDA-MB-468 cell was 73.2 ± 6.7 Gy, whereas (177)Lu-NT-AuNP delivered 5.6 ± 0.6 Gy. We conclude that (177)Lu-T-AuNP is a promising novel radiation nanomedicine with potential application for treatment of TNBC, in which EGFR are often overexpressed.
