Abstract
Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease characterized by the neurodegeneration of motoneurons. About 10% of ALS is hereditary and involves mutation in 25 different genes, while 90% of the cases are sporadic forms of ALS (sALS). The diagnosis of ALS includes the detection of early symptoms and, as disease progresses, muscle twitching and then atrophy spreads from hands to other parts of the body. The disease causes high disability and has a high mortality rate; moreover, the therapeutic approaches for the pathology are not effective. miRNAs are small non-coding RNAs, whose activity has a major impact on the expression levels of coding mRNA. The literature identifies several miRNAs with diagnostic abilities on sALS, but a unique diagnostic profile is not defined. As miRNAs could be secreted, the identification of specific blood miRNAs with diagnostic ability for sALS could be helpful in the identification of the patients. In the view of personalized medicine, we performed a meta-analysis of the literature in order to select specific circulating miRNAs with diagnostic properties and, by bioinformatics approaches, we identified a panel of 10 miRNAs (miR-193b, miR-3911, miR-139-5p, miR-193b-1, miR-338-5p, miR-3911-1, miR-455-3p, miR-4687-5p, miR-4745-5p, and miR-4763-3p) able to classify sALS patients by blood analysis. Among them, the analysis of expression levels of the couple of blood miR-193b/miR-4745-5p could be translated in clinical practice for the diagnosis of sALS.

Predictive value of 1q21 gain in multiple myeloma is strongly dependent on concurrent cytogenetic abnormalities and first-line treatment. Am J Cancer Res 2021; 11:4438-4454.

Abstract
Improved therapies in multiple myeloma (MM) have forced a constant risk stratification update, first Durie-Salmon, then international scoring systems (ISS), next revised-ISS (RISS) including high-risk cytogenetic abnormalities (HRCAs) such as del(17p) and t(4;14), and now R2-ISS including 1q21 gain has been proposed. Predictive value of 1q21 gain by itself or in concurrence with other cytogenetic abnormalities is evaluated in 737 real-world plasma cell neoplasm (PCN) patients under current therapies. Ten-year progression-free survival (10y-PFS) rates for patients with 2, 3 and >3 copies of 1q21 were 72.2%, 42.5% and 43.4% (P<1.1×10-17). Cox regression analysis confirmed that 1q21 gain was an independent prognostic factor for PFS (HR=1.804, P<0.0001, Harrell C-statistic =0.7779±0.01495) but not for OS (P=0.131). Gain of 1q21 was strongly associated with hypodiploidy (38.8% vs. 7.0%, P=1.3×10-22), hyperdiploidy (44.1% vs. 16.4%, P=1.6×10-13), HRCAs (12.6% vs. 3.5%, 1.8×10-5), IGH breaks (12.3% vs. 2.1%, P=2.1×10-7) and del(13q) (8.0% vs. 4.0%, P=0.031). In our series, 1q21 gain by itself did not improve RISS predictive capacity in patients either eligible or ineligible for autologous stem cell transplantation (ASCT). However, compared with patients with other 1q21 gains: concurrence with hyperdiploidy improved the prognosis of ASCT-eligible patients from 62.5% to 96.0% 10-year overall-survival (10y-OS, P<0.002); concurrence with hypodiploidy improved the prognosis of ASCT-ineligible patients from 35.7% to 71.0% (P=0.013); and concurrence with del(13q) worsened the prognosis of ASCT-ineligible patients from 12.5% to 53.4% (P=0.035). Gain of 1q21 should be patient-wisely evaluated, irrespective of the RISS, considering its concurrence with other cytogenetic abnormalities and eligibility for ASCT.

Abstract
Purpose. 1-Octadecene is a hydrocarbon with one double bond in its structure that could serve as a solvent for ferrofluids. The aim of this pilot study was to obtain preliminary information on intraocular tolerance to 1-octadecene. Methods. Vitreous compression with perfluoropropane gas was achieved in 20 eyes of albino rabbits. Four days after gas injection a fluid-gas exchange was undertaken. Sixteen eyes received 1-octadecene. Four eyes received balanced salt solution. Eyes were obtained at 3, 7, 14 and 30 days. The samples were fixed in 10% buffered formalin, processed in paraffin and sections were stained with hematoxylin and eosin. Results. Emulsification of the oil bubble was observed in 31.25% of the cases by the fifth day; light microscopy showed normal retinal architecture in all the eyes and epiretinal and vitreous macrophages in 50% of the eyes. Conclusions. 1-Octadecene does not appear to have any retinal cytotoxic effect but elicits an inflammatory response in the vitreous activity.

Abstract
This study aimed to describe a gradient repeated sprint ability (RSA) test in comparison with a standard level one by investigating performance, metabolic demand and muscular jumping performance as a proxy for running mechanics. Eighteen athletes performed two level RSA tests (40 m × 6) - for reliability evaluation - and one ±5% gradient RSA test, second leg downhill (RSAgrad). Rating of perceived exertion (RPE), blood lactate concentration (BLa) concentration, vertical jump heights were assessed as well. Level test measures resulted highly reliable (Intra-class correlation coefficient (ICC) ≥0.96). RSAgrad worsened only first sprints' performance (-2%) but not overall test performance (~45 s). RSAgrad resulted to be less deteriorating in terms of fatigue index (FI) (-36%), BLa (-23%), RPE (-11%), jumping performance (RSAgrad post-/pre-squat jump, countermovement jump heights (CMJh): -3%, -6%, respectively). RSAgrad could be used to diversify common training protocol without stressing excessively athletes' current metabolic-anaerobic capacity. Such physical conditioning procedures could improve acceleration/braking capability.

Abstract
Microarray experiments have made possible to identify breast cancer marker gene signatures. However, gene expression-based signatures present limitations because they do not consider metabolic role of the genes and are affected by genetic heterogeneity across patient cohorts. Considering the activity of entire pathways rather than the expression levels of individual genes can be a way to exceed these limits. We evaluated and compared five methods of pathway-level aggregation of gene expression data. Our results confirmed the important role of pathway expression profile in breast cancer diagnostic classification (accuracy >90%). However, although assessed on a limited number of samples and datasets, this study shows that using dissimilarity representation among patients does not improve the classification of pathway-based expression profiles.

Abstract
Specific genome copy number alterations, such as deletions and amplifications are an important factor in tumor development and progression, and are also associated with changes in gene expression. By combining analyses of gene expression and genome copy number we identified genes as candidate biomarkers of BC which were validated as prognostic factors of the disease progression. These results suggest that the proposed combined approach may become a valuable method for BC prognosis.
