An effect of chromium on mechanical properties of the Ni3Al-Based alloys and sinters in compression tests

Mechanical properties of the Ni75Al(25-x)Crx cast alloys and sinters were investigated using compression tests conducted within a wide range of compositions and temperature. The alloys and sinters exhibiting the best mechanical properties from a point of view of their intended use as constructional materials suitable for high-temperature applications were selected

The role of systemic therapies of non-small cell lung cancer and malignant pleural mesothelioma: updated expert recommendations

Rak płuca jest w Polsce najczęstszą przyczyną zgonów nowotworowych. Około 85% wszystkich nowotworów płuca stanowi rak niedrobnokomórkowy (NDRP), w którym leki cytotoksyczne i ukierunkowane molekularnie odgrywają coraz większą rolę. W pracy przedstawiono oparte na obecnej wiedzy zalecenia dotyczące stosowania tych metod w praktyce klinicznej u chorych na NDRP oraz na złośliwego międzybłoniaka opłucnej.Lung cancer is the leading cause of cancer related death in Poland. About 85% of all lung cancer constitutes non-small cancer (NSCLC), in which the role of cytotoxic and molecularly targeted drugs is increasing. This article presents the current evidence-based recommendations for the use of these methods in clinical practice in NSCLC and malignant pleural mesothelioma

BRCA1: A Novel Prognostic Factor in Resected Non-Small-Cell Lung Cancer

BACKGROUND: Although early-stage non-small-cell lung cancer (NSCLC) is considered a potentially curable disease following complete resection, patients have a wide spectrum of survival according to stage (IB, II, IIIA). Within each stage, gene expression profiles can identify patients with a higher risk of recurrence. We hypothesized that altered mRNA expression in nine genes could help to predict disease outcome: excision repair cross-complementing 1 (ERCC1), myeloid zinc finger 1 (MZF1) and Twist1 (which regulate N-cadherin expression), ribonucleotide reductase subunit M1 (RRM1), thioredoxin-1 (TRX1), tyrosyl-DNA phosphodiesterase (Tdp1), nuclear factor of activated T cells (NFAT), BRCA1, and the human homolog of yeast budding uninhibited by benzimidazole (BubR1). METHODOLOGY AND PRINCIPAL FINDINGS: We performed real-time quantitative polymerase chain reaction (RT-QPCR) in frozen lung cancer tissue specimens from 126 chemonaive NSCLC patients who had undergone surgical resection and evaluated the association between gene expression levels and survival. For validation, we used paraffin-embedded specimens from 58 other NSCLC patients. A strong inter-gene correlation was observed between expression levels of all genes except NFAT. A Cox proportional hazards model indicated that along with disease stage, BRCA1 mRNA expression significantly correlated with overall survival (hazard ratio [HR], 1.98 [95% confidence interval (CI), 1.11-6]; P = 0.02). In the independent cohort of 58 patients, BRCA1 mRNA expression also significantly correlated with survival (HR, 2.4 [95%CI, 1.01-5.92]; P = 0.04). CONCLUSIONS: Overexpression of BRCA1 mRNA was strongly associated with poor survival in NSCLC patients, and the validation of this finding in an independent data set further strengthened this association. Since BRCA1 mRNA expression has previously been linked to differential sensitivity to cisplatin and antimicrotubule drugs, BRCA1 mRNA expression may provide additional information for customizing adjuvant antimicrotubule-based chemotherapy, especially in stage IB, where the role of adjuvant chemotherapy has not been clearly demonstrated

Recommendations for implementing lung cancer screening with low-dose computed tomography in Europe

Lung cancer screening (LCS) with low-dose computed tomography (LDCT) was demonstrated in the National Lung Screening Trial (NLST) to reduce mortality from the disease. European mortality data has recently become available from the Nelson randomised controlled trial, which confirmed lung cancer mortality reductions by 26% in men and 39–61% in women. Recent studies in Europe and the USA also showed positive results in screening workers exposed to asbestos. All European experts attending the “Initiative for European Lung Screening (IELS)”—a large international group of physicians and other experts concerned with lung cancer—agreed that LDCT-LCS should be implemented in Europe. However, the economic impact of LDCT-LCS and guidelines for its effective and safe implementation still need to be formulated. To this purpose, the IELS was asked to prepare recommendations to implement LCS and examine outstanding issues. A subgroup carried out a comprehensive literature review on LDCT-LCS and presented findings at a meeting held in Milan in November 2018. The present recommendations reflect that consensus was reached
