B Rossi, S Marquart, G Rossi
The study addresses the life cycle cost assessment (LCCA) of steel bridges, focusing on the maintenance activities and the maintenance scenario. Firstly, the unit costs of maintenance activities and their durability (i.e. the time between two activities) are evaluated. Pragmatic data are provided for the environment category C4 and for three activities: Patch Up, Overcoating and Remove & Replace. A comparative LCCA for a typical hypothetic steel girder bridge is carried out, either painted or hot-dip galvanized (HDG), in the environmental class C4...

Primary mediastinal large B-cell lymphoma (PMLBCL) is a distinct clinical and biological disease from other types of DLBCL. It is more frequent in young female and constitutes 6%-10% of all DLBCL. PMLBCL is characterized by a diffuse proliferation of medium to large B-cells associated with sclerosis. Molecular analysis shows it to be a distinct entity from other DLBCL. Rituximab CHOP/MACOP-B-like regimens followed by mediastinal radiotherapy (RT) were associated with a 5-years PFS of 75%-85%. More intensive regimens, as DA-EPOCH-R without mediastinal RT, have shown very promising results, but this therapeutic advance needs to be confirmed in further prospective trials...

Snehapana i.e. internal administration of fat is the essential step prior to Vamana and Virechana (therapeutic vomiting and purgation). But it was found that 10-15% patients has got reluctance towards Snehapana hence may deprive the benefits of Shodhana. These inconveniences made us think about effective alternative to counter drawbacks of Snehapana. On the basis of literary review and pilot study, it was confirmed that, Anuvasana Basti can be administered as an alternative for Snehapana. To evaluate samyak snigdha lakshana i...

BACKGROUND: CD8+ T cell-eliciting vaccines are being investigated in breast cancer patients. Preclinical data showed that trastuzumab increases the susceptibility of tumor cells to lysis by vaccine-generated CD8+ T cells, suggesting potential benefit of a combination immunotherapy strategy. The current trial was undertaken to demonstrate the safety of this approach. METHODS: This study was designed as a dose-escalation trial enrolling clinically disease-free, human leukocyte antigen A2+ or A3+ , human epidermal growth factor receptor 2 (HER2)-positive breast cancer patients...

LESSONS LEARNED: The combination of standard dose abiraterone acetate and BEZ235, a pan-class I PI3K and mTORC1/2 inhibitor, was poorly tolerated in men with progressive mCRPC.Although the clinical development of BEZ235 has been discontinued in prostate cancer, agents that more selectively target PI3K-AKT-mTOR signaling may have a more favorable therapeutic index and should continue to be explored. BACKGROUND: Androgen receptor (AR) and phosphatidylinositol-3 kinase (PI3K) signaling are two commonly perturbed pathways in prostate cancer...

Heat Shock Protein 90 (HSP90) regulates multiple signaling pathways critical for tumor growth. As such, HSP90 inhibitors have been shown to act as effective anticancer agents in preclinical studies but, for a number of reasons, the same effect has not been observed in the clinical trials to date. One potential reason for this may the presence of de novo or acquired resistance within the tumors. To investigate mechanisms of resistance, we generated resistant cell lines through gradual dose escalation of the HSP90 inhibitor 17-AAG...

Despite improvements in guidewire technologies, the traditional antegrade wire escalation approach to chronic total occlusion (CTO) recanalization is successful in only 60-80% of selected cases. In particular, long, calcified, and tortuous occlusions are less successfully approached with a true-to-true lumen approach. Frequently, the guidewire tracks into the subadventitial space, with no guarantee of distal re-entry into the true lumen. The ability to manage the subadventitial space has been a key step in the tremendous improvement in success rates of contemporary CTO percutaneous coronary intervention (PCI), whether operating antegradely or retrogradely...

Lymphatic filariasis (LF) and onchocerciasis are priority neglected tropical diseases targeted for elimination. The only safe drug treatment with substantial curative activity against the filarial nematodes responsible for LF (Brugia malayi, Wuchereria bancrofti) or onchocerciasis (Onchocerca volvulus) is doxycycline. The target of doxycycline is the essential endosymbiont, Wolbachia. Four to six weeks doxycycline therapy achieves >90% depletion of Wolbachia in worm tissues leading to blockade of embryogenesis, adult sterility and premature death 18-24 months post-treatment...

Adolescence is a gradual period of transition from childhood to adulthood. It is considered as a sensitive developmental time point that long lasting changes occur in the brain. The present study examined adolescent chronic escalating morphine administration on morphine tolerance and dependence in adulthood. Adolescent male Wistar rats (30days old) were administered increasing doses of morphine (2.5 to 25mg/kg, s.c.) every 12h, for 10days. Control rats received saline according to the same protocol. Thereafter, during adulthood (65-75days old), tolerance to antinociceptive effect of morphine was induced by subcutaneous injection of 3mg/kg morphine, once a day for 7days...

OBJECTIVES: The improved passive immune thrombocytopenia (ITP) mouse model has been extensively utilized for the study of ITP. However, how closely this model matches the human inflammation state and immune background is unclear. Our study aimed to explore the profile of Th cytokines and Th17/Treg cells in the model. METHODS: We induced the ITP mouse model by dose-escalation injection of MWReg30. The serum levels of cytokines (IFN-γ, IL-2, IL-4, IL-10, IL-17A, and TGF-β1) were measured by enzyme-linked immunosorbent assay and the frequency of Th17 and Treg cells was measured by flow cytometry...

In the two-stage continual reassessment method (CRM), model-based dose escalation is preceded by a pre-specified escalating sequence starting from the lowest dose level. This is appealing to clinicians because it allows a sufficient number of patients to be assigned to each of the lower dose levels before escalating to higher dose levels. While a theoretical framework to build the two-stage CRM has been proposed, the selection of the initial dose-escalating sequence, generally referred to as the initial design, remains arbitrary, either by specifying cohorts of three patients or by trial and error through extensive simulations...
