All Nervi’s works bear the stamp of his unique qualities as an engineer. At the same time, they were always closely related to the cultural and social conditions both domestically and worldwide, which changed consid-erably during his long working life (from twenties to seventies): from World War One through the Fascist era to the enthusiastic second post-war reconstruction period, and on to the booming years of economic euphoria up to financial crisis of the seventies. For this reason, upon reviewing his works, it seems to us that Pier Luigi Nervi lived not one but three lives in that he was a modern architect, a builder creator of a new building method, and an international star-architect. Three equally intense lives that coexisted, overlapped and interacted but remained independent of each other. This paper tell briefly about the three lives of Nervi.

Todos los trabajos de Nervi llevan el sello de sus cualidades únicas como ingeniero. Al mismo tiempo, siempre estuvieron estrechamente relacionados con las condiciones culturales y sociales, tanto a nivel nacional como mun-dial, que cambiaron considerablemente durante su larga vida laboral (de los años veinte a los setenta): desde la Primera Guerra Mundial, pasando por la era fascista, hasta el entusiasta período de reconstrucción de la segunda posguerra, y los años de euforia económica hasta la crisis financiera de los setenta. Por esta razón, al revisar sus obras, nos parece que Pier Luigi Nervi vivió no una, sino tres vidas en la que fue un arquitecto moderno, un constructor creador de un nuevo método de construcción y un arquitecto estrella internacional. Tres vidas igualmente intensas que coexistieron, se superpusieron e interactuaron pero permanecieron independientes entre sí. Este artículo habla brevemente sobre las tres vidas de Nervi.

The aim of this study is to evaluate memantine effectiveness on behavioural and psychological symptoms of dementia (BPSD) in clinical practice and to identify variables that may predict the therapy effects. The effects of memantine on behaviour were analysed in the database of a post-marketing surveillance study promoted by the Lombardy Region Health Office and involving 43 Alzheimer’s disease (AD) Units. From July to December 2005, 399 moderately severe-to-severe AD patients free of cholinergic medications were enrolled, treated with memantine and followed-up for 6 months. BPSD were assessed in a subgroup of 297 patients [mean age 77 ± 8 years; 73% females; mean neuropsychiatric inventory (NPI) score 28 ± 24] for whom the 12-item NPI subscores at baseline, and at 3 and 6 months were available. The 12 BPSD were clustered as follows: affect, physical behaviour, psychosis and hypomania. The main outcome measure was the proportion of individual cluster responders at 6 months of therapy. The proportion of individual cluster responders was 30% affect, 24% physical behaviour, 29% psychosis, 27% hypomania. Patients taking 20 mg memantine daily during the study period had a statistically significant higher probability to experience behavioural improvement than those who discontinued treatment or did not complete memantine titration (affect OR 9.0; 95% CI 3.8–21.6; physical behaviour OR 17.8; 95% CI 5.9–53.6; psychosis OR 23.6; 95% CI 5.1–110.8). The logistic regression analysis was not applicable to the hypomania subsyndrome because of the low cluster prevalence. The standard 20 mg daily memantine treatment regimen was found to be associated with a modest 6-month behavioural improvement in the affect, physical behaviour and psychosis domains in 24–30% of patients.

Background: Postmarketing surveillance studies (PMS) are an important tool for evaluating a drug’s effectiveness and safety in clinical practice. To our knowledge, no PMS on memantine monotherapy for moderately-severe-to-severe Alzheimer’s disease (AD) according to National Institute of Neurological and Communicative Disorders and Stroke — Alzheimer’s Disease and Related Disorders Association criteria has been conducted to date. Objective: The Lombardy Health Office, Italy, promoted this PMS to evaluate the effectiveness and safety of memantine in the treatment of moderately-severe-to-severe AD in clinical practice. Methods: A total of 451 patients with moderately-severe-to-severe AD (mean age 77 ± 7 years; 72% female), free of cholinergic medication, received memantine (standard titration to 10 mg twice daily). After 6 months of therapy, treatment effectiveness was evaluated according to two definitions of response (‘no deterioration’ and ‘improvement’), as measured by changes in baseline scores on the Clinical Global Impression of Change, Mini-Mental State Examination, Neuropsychiatric Inventory and Activities of Daily Living scales. The safety measure was the frequency of adverse events (AEs). Results: At 6-month assessment, 26.8% of subjects showed no deterioration and 3.8% showed improvement. In those showing no deterioration, response to treatment at the 3-month assessment was associated with a greater probability of a response at 6 months (adjusted odds ratio = 8.54; 95% CI 4.54, 16.05). Seventy patients (15.5%) experienced at least one AE and 39 (8.6%) discontinued treatment prematurely because of an AE. Of those who experienced an AE, 27 (38.6%) manifested behavioural and psychological symptoms of dementia. Conclusion: The proportion of responders to memantine treatment in this PMS was similar to that reported in a previous randomized clinical trial (26.8% vs 29%, respectively). The proportion of patients who discontinued treatment prematurely because of an AE (8.6%) was similar to that reported in two previous randomized clinical trials (10% and 12.4%). This PMS provides additional evidence that both the effectiveness and the tolerability of memantine may be transferred into real world medicine, where AD patients receiving treatment are not selected according to strict criteria.

The use of plant-derived products as antimicrobial agents has been investigated in depth. Isothiocyanates (ITCs) are bioactive products resulting from enzymatic hydrolysis of glucosinolates (GLs), the most abundant secondary metabolites in the botanical order Brassicales. Although the antimicrobial activity of ITCs against foodborne and plant pathogens has been well documented, little is known about their antimicrobial properties against human pathogens. This review collects studies that focus on this topic. Particular focus will be put on ITCs’ antimicrobial properties and their mechanism of action against human pathogens for which the current therapeutic solutions are deficient and therefore of prime importance for public health. Our purpose was the evaluation of the potential use of ITCs to replace or support the common antibiotics. Even though ITCs appear to be effective against the most important human pathogens, including bacteria with resistant phenotypes, the majority of the studies did not show comparable results and thus it is very difficult to compare the antimicrobial activity of the different ITCs. For this reason, a standard method should be used and further studies are needed.

FMRFamide-gated Na+ channel (FaNaC) is a member of the DEG/ENaC family and activated by a neuropeptide, FMRFamide. Structural information about the FMRFamide-dependent gating is, however, still elusive. Because two phenylalanines of FMRFamide are essential for the activation of FaNaC, we hypothesized that aromatic-aromatic interaction between FaNaC and FMRFamide is critical for FMRFamide recognition and/or the activation gating. Here, we focused on eight conserved aromatic residues in the finger domain of FaNaCs and tested our hypothesis by mutagenic analysis and in silico docking simulations. The mutation of conserved aromatic residues in the finger domain reduced the FMRFamide potency, suggesting that the conserved aromatic residues are involved in the FMRFamide-dependent activation. The kinetics of the FMRFamide-gated currents were also modified substantially in some mutants. Some results of docking simulations were consistent with a hypothesis that the aromatic-aromatic interaction between the aromatic residues in FaNaC and FMRFamide is involved in the FMRFamide recognition. Collectively, our results suggest that the conserved aromatic residues in the finger domain of FaNaC are important determinants of the ligand recognition and/or the activation gating in FaNaC.

This work presents and compares two formulations for the co-design optimization of a wind turbine blade under non-linear transient loads: the Nested Analysis and Design (NAND) and the Simultaneous Analysis and Design (SAND) approaches. Analytic sensitivies are used in order to ensure the convergence of the optimization within reasonable computational resources. The two formulations are compared on a mass minimization problem with dynamic constraints, solved with the interior-point method in IPOPT, for a gust input and a turbulent input. Results shows that the NAND and SAND approaches converge towards the same optimum with similar performances. The SAND approach benefits from a simpler design sensitivity analysis and a sparse jacobian of the constraints.

Uterus transplantation (UTx) is a potential option for women with uterine factor infertility to have a child. The clinical features indicating irreversible rejection of the uterus are unknown. In our experimental series of allogeneic UTx in cynomolgus macaques, six female macaques were retrospectively examined, which were unresponsive to treatment with immunosuppressants (i.e. irreversible rejection). Clinical features including general condition, hematology, uterine size, indocyanine green (ICG) fluorescence imaging by laparotomy, and histopathological findings of the removed uterus were evaluated. In all cases, general condition was good at the time of diagnosis of irreversible rejection and thereafter. Laboratory evaluation showed temporary increases in white blood cells, lactate dehydrogenase and C-reactive protein, then these levels tended to decrease gradually. In transabdominal ultrasonography, the uterus showed time-dependent shrinkage after transient swelling at the time of diagnosis of irreversible rejection. In laparotomy, a whitish transplanted uterus was observed and enhancement of the transplanted uterus was absent in ICG fluorescence imaging. Histopathological findings in each removed uterus showed hyalinized fibrosis, endometrial deficit, lymphocytic infiltration and vasculitis. These findings suggest that uterine transplantation rejection is not fatal, in contrast to rejection of life-supporting organs. Since the transplanted uterus with irreversible rejection atrophies naturally, hysterectomy may be unnecessary.

Skeletal muscle atrophy is the decrease in muscle mass and strength caused by reduced protein synthesis/accelerated protein degradation. Various conditions, such as denervation, disuse, aging, chronic diseases, heart disease, obstructive lung disease, diabetes, renal failure, AIDS, sepsis, cancer, and steroidal medications, can cause muscle atrophy. Mechanistically, inflammation, oxidative stress, and mitochondrial dysfunction are among the major contributors to muscle atrophy, by modulating signaling pathways that regulate muscle homeostasis. To prevent muscle catabolism and enhance muscle anabolism, several natural and synthetic compounds have been investigated. Recently, polyphenols (i.e., natural phytochemicals) have received extensive attention regarding their effect on muscle atrophy because of their potent antioxidant and anti-inflammatory properties. Numerous in vitro and in vivo studies have reported polyphenols as strongly effective bioactive molecules that attenuate muscle atrophy and enhance muscle health. This review describes polyphenols as promising bioactive molecules that impede muscle atrophy induced by various proatrophic factors. The effects of each class/subclass of polyphenolic compounds regarding protection against the muscle disorders induced by various pathological/physiological factors are summarized in tabular form and discussed. Although considerable variations in antiatrophic potencies and mechanisms were observed among structurally diverse polyphenolic compounds, they are vital factors to be considered in muscle atrophy prevention strategies.
