Benefits of a home-based physical exercise program in elderly subjects with type 2 diabetes mellitus
2011
Abstract Objective To analyze the effects of a home-based physical exercise program on quality of life, metabolic control, and anthropometric and biochemical parameters in people over 60 years of age with type 2 diabetes mellitus. Methods Eighty-four Spanish patients aged over 60 years were finally randomized to participate in a home-based, combined physical exercise program (aerobic and anaerobic exercises) or to receive conventional treatment for diabetes. At 6 months, effects on quality of life (EuroQoL questionnaire), HbA1c, fasting glucose, hypoglycemic events, weight, BMI, waist circumference, blood pressure, and biochemical parameters were assessed. Results Mean age of study particip…
COX-1/COX-2 inhibitors based on the methanone moiety
2002
This paper focuses on the synthesis and the in vitro testing of dual COX-1/COX-2 inhibitors. Starting from structures of non-steroidal anti-inflammatory drugs (NSAIDs) the diaryl methanone element was chosen as a lead. Modifications were carried out on this scaffold to obtain potent inhibitors of the COX enzymes. The N-(2-aroylphenyl)sulphonamides and -amides were studied in detail, and to consolidate the data evaluated the corresponding 3- and 4-regioisomers were also investigated. The potency and the enzyme selectivity were varied by structural modifications of the lead.
In-vitro test system for the evaluation of cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) inhibitors based on a single HPLC run with UV detect…
2001
Objective and Design: The aim of this study was to develop a new, whole-cell test system which is easy to handle and requires a standard equipment for the parallel screening of COX-1 and COX-2 inhibitors.¶Materials: Bovine aortic endothelial cells (BAECs).¶Treatment and methods: Unstimulated bovine aortic coronary endothelial cells (BAECs) were used as a source of COX-1 and BAECs pretreated with ASA (100 μM) and activated with phorbol myristate acetate (PMA) were used as a source of COX-2. The time- and concentration-dependent induction of COX-2 expression in the BAECs was evaluated by a kinetic profile (HPLC analysis) and detected by Western-Blot analysis using polyclonal antibodies agains…
La valutazione del Consiglio di Amministrazione in contesti ad elevata concentrazione proprietaria: mero conformismo o reale strumento di valutazione?
2018
Board evaluation is a best practice required on voluntary bases by Code of conduct. Despite its voluntary nature, companies very likely adopted this recommendation because the failure to adopt could have a negatively impact on company legitimation and reputation. Moreover, the implementation modalities of BE, however, could be negatively influenced by the specific companies’ ownership structure. The ownership concentration and the search for corporate legitimacy can lead at two possible situations: the BE have only formally adoption or BE have adoption in form and substance. What prevails in the context of ownership concentrated firms? Companies adopt the recommendation to comply with other…
Managing Human Factors to Reduce Organisational Risk in Industry
2018
[EN] Human factors are intrinsically involved at virtually any level of most industrial/business activities, and may be responsible for several accidents and incidents, if not correctly identified and managed. Focusing on the significance of human behaviour in industry, this article proposes a multi-criteria decision-making (MCDM)-based approach to support organizational risk assessment in industrial environments. The decision-making trial and evaluation laboratory (DEMATEL) method is proposed as a mathematical framework to evaluate mutual relationships within a set of human factors involved in industrial processes, with the aim of highlighting priorities of intervention. A case study relat…
A Neuroprotective Function for the Hematopoietic Protein Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF)
2007
Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a hematopoietic cytokine responsible for the proliferation, differentiation, and maturation of cells of the myeloid lineage, which was cloned more than 20 years ago. Here we uncovered a novel function of GM-CSF in the central nervous system (CNS). We identified the GM-CSF α-receptor as an upregulated gene in a screen for ischemia-induced genes in the cortex. This receptor is broadly expressed on neurons throughout the brain together with its ligand and induced by ischemic insults. In primary cortical neurons and human neuroblastoma cells, GM-CSF counteracts programmed cell death and induces BCL-2 and BCL-Xl expression in a dose- a…
Hirsutane-Type Sesquiterpenes with Uncommon Modifications from Three Basidiomycetes
2010
From three basidiomycetes, Xeromphalina sp., Stereum sp., and Pleurocybella porrigens, six triquinane sesquiterpenes with unprecendented modifications and a rearranged sesquiterpene related to coriolin C have been isolated. Their isolation, structure elucidation, and biological evaluation are described.
Drug Screening Boosted by Hyperpolarized Long-Lived States in NMR
2014
International audience; : Transverse and longitudinal relaxation times (T1ρ and T1 ) have been widely exploited in NMR to probe the binding of ligands and putative drugs to target proteins. We have shown recently that long-lived states (LLS) can be more sensitive to ligand binding. LLS can be excited if the ligand comprises at least two coupled spins. Herein we broaden the scope of ligand screening by LLS to arbitrary ligands by covalent attachment of a functional group, which comprises a pair of coupled protons that are isolated from neighboring magnetic nuclei. The resulting functionalized ligands have longitudinal relaxation times T1 ((1) H) that are sufficiently long to allow the powerf…
Ultrasonic nondestructive testing of building materials for the diagnosis and characterization of the decay due to salts crystallization
2020
The possibility to use ultrasonic nondestructive testing for the diagnosis and characterization of decay in building materials due to salts crystallization is here investigated. Salts crystallization is one of the main sources of decay for stone materials, especially for cultural heritage items underwater or exposed to water, and its early detection as well as a continuous monitoring is highly desirable. Currently, this often requires the use of destructive methods and the sampling of the items under inspection. This work shows promises to the successful use for this purpose of ultrasonic nondestructive testing.
DIGITAL MARKETING PERFORMANCE EVALUATION METHODS
2018
The share of digital marketing from total marketing spending is increasing fast year by year. Still the majority of companies admit that they are missing clear methods on how to evaluate (positive/negative) effects obtained using digital marketing. As this field of digital marketing is relatively new, there are no firm and widely recognized measurement methods resulting in marketing specialists being confused by an overwhelming amount and variety of different digital marketing metrics and large amounts of data. Therefore, the aim of this paper is to list the existing methods which could help marketers to evaluate their digital marketing campaign effectiveness and to discuss these methods’ e…
