The glass fiber-reinforced polymer (GFRP) materials of wind turbine blades can be recovered and recycled by crushing, thereby solving one of the most perplexing problems facing the wind energy sector. This process yields selectively crushed wind turbine blade (SCWTB), a novel waste that is almost exclusively composed of GFRP composite fibers that can be revalued in terms of their use as a raw material in concrete production. In this research, the fresh and mechanical performance of concrete made with 1.

In this paper, the performance of ladle furnace slag (LFS), a by-product of secondary steel refining, is evaluated as a binder to stabilize clayey soils of low bearing capacity. The aim is to define whether additions of this by-product to clayey soil can stabilize the soil in accordance with the technical specifications of Spanish standards. To do so, three different soils stabilized with 5% LFS were compared with the same soils stabilized with 2% lime and with no stabilization, in order to investigate their different behaviors.

The recovery of face-to-face teaching after lockdown meant that classes were taught with obligatory social distancing and the use of masks. Teachers were therefore unable to interact with students closely, to perceive their facial expressions during class, or to conduct group work.

Here, we developed an model with the aim of reproducing the effects of the microenvironment that would help shed light on the mechanism of action of idelalisib and ibrutinib and predict their clinical efficacy in individual patients. First we explored the effects of various cell-extrinsic elements on CLL apoptosis and proliferation and found that the combination of CpG+IL2+HS5 stromal cell line + human serum +CLL plasma and erythrocyte fractions represented the best co-culture conditions to test the effects of the novel inhibitors.

To address this, we have developed an automated flow cytometry platform for drug screening that evaluates multiple endpoints with a robust data analysis system that can capture the complex mechanisms of action across different compounds. This system, called PharmaFlow, is used to test peripheral blood or bone marrow samples from patients diagnosed with hematological malignancies.

To date, no studies have been reported in which the entire chromosome 14q of meningioma tumour cells has been studied by high-resolution array comparative genomic hybridization (a-CGH). Here, we used a high-resolution a-CGH to define the exact localization and extent of numerical changes of chromosome 14 in meningioma patients.

We analyzed the characteristics of meningiomas from male (n = 53) and female (n = 111) patients by interphase fluorescence in situ hybridization (iFISH). In addition, in a subgroup of 45 (12 male and 33 female) patients, tumors were hybridized with the Affymetrix U133A chip.

In this study, we analyzed the prognostic value of specific chromosomal abnormalities and the genetic heterogeneity of the tumor, together with other clinicobiological disease features, for predicting early relapses in histologically benign/grade I meningiomas. A total of 149 consecutive histologically benign/grade I meningiomas in patients who underwent complete tumor resection were prospectively analyzed.

Here, we compare the clinico-biological characteristics as well as the genetic abnormalities and patterns of gene expression of spinal and intracranial meningiomas. Fourteen spinal and 141 intracranial meningioma patients were analyzed at diagnosis.

Analysis of purified cell populations confirmed the involvement of the neutrophil (89%), monocytic (89%), eosinophil (88%), erythroid (100%), and CD34(+) cells (100%) in virtually all patients, without differences between minor BCR/ABL+ and major BCR/ABL+ cases; BCR/ABL+ B- and natural killer (NK)-cells were detected in 43% and 31% of cases, respectively, whereas BCR/ABL+ T-cells were rare (7%). All three minor BCR/ABL+ patients showed involvement of both B- and NK-cells, which was infrequent (27%, P = 0.

The aim of the present study is to analyze the cytogenetic relationship between primary and subsequent recurrent meningiomas developed within the same individual.
Experimental Design: Multicolor interphase fluorescence in situ hybridization was done for the identification of numerical abnormalities of 12 chromosomes in single-cell suspensions from 59 tumor samples corresponding to 25 recurrent meningioma patients.

We analyzed quantitative chromosome 14 abnormalities in 124 meningiomas by interphase fluorescence in situ hybridization (iFISH) and confirmed the nature of abnormalities by comparative genomic hybridization (CGH). We correlated the abnormalities with clinical, histopathologic, and prognostic factors. Of 124 cases, 50 (40.
