Chromogenic detection of nerve agent mimics
2008
The current rise in international concern over criminal terrorist attacks via chemical warfare (CW) agents has resulted in an increasing interest in the detection of these lethal chemicals. Among CW species, nerve agents are extremely dangerous and their high toxicity and ease of production underscore the need to detect these deadly chemicals via quick and reliable procedures. A number of detection systems have been developed, most of them based on enzymatic and physical methodologies. However, these usually show limitations such as low selectivity, lack of portability and a certain complexity in their use. An alternative to these classical methods that has been gaining interest in recent y…
Extracellular matrix regulation of PTHrP and PTH/PTHrP receptor in a human breast cancer cell line
1999
AbstractIt was previously reported that 8701-BC breast cancer cells express the gene for parathyroid hormone-related peptide (PTHrP) and its cognate receptor (PTHrP-R), and release immunoreactive PTHrP in the extracellular medium; it was also found that PTHrP, in turn, exerts a role on the proliferative and invasive behavior in vitro of the same cell line. On the other hand, evidence has been produced that adhesion of 8701-BC cells onto different collagen substrates influences in various ways a number of phenotypic expressions, such as cell growth, motility, invasion of reconstituted basement membrane and production of lytic enzymes of the extracellular matrix (ECM). In light of these previ…
MINIMIZING INFLIXIMAB TOXICITY IN THE TREATMENT OF INFLAMMATORY BOWEL DISEASE
2008
Abstract Background Infliximab is a widely used biological agent for the treatment of inflammatory bowel disease, and has a favorable risk/benefit ratio. Aim It is useful to know that patients treated with infliximab are exposed to developing adverse events that could be reduced with a prudent and a rational clinical approach and by optimizing the treatment protocol. Methods PubMed (including Epub) was searched in October 2006 and again in March 2007. Results The high immunogenic potential of infliximab determines the antibodies that inhibit the effect of infliximab and the appearance of subsequent acute and delayed infusion reactions. Infliximab has an immunomodulatory effect, thus increas…
Abatacept as Adjunctive Therapy in Refractory Polymyalgia Rheumatica.
2021
Glucocorticoids (GCs) are the mainstay of treatment for patients with polymyalgia rheumatica (PMR).1 Despite their efficacy, GCs are associated with well-known adverse events and a substantial proportion of patients with PMR do not respond adequately, or are refractory, to initial GC treatment. GC-sparing agents in PMR are limited to methotrexate (MTX).1.
Multiphoton Absorption of Myoglobin Nitric-Oxide complex: Relaxation by D-NEMD of a Stationary State
2012
ABSTRACT: The photodissociation and geminate recombination of nitric oxide in myoglobin, under continuous illumination, is modeled computationally. The relaxation of the photon energy into the protein matrix is also considered in a single simulation scheme that mimics a complete experimental setup. The dynamic approach to non-equilibrium molecular dynamics is used, starting from a steady state, to compute its relaxation to equilibrium. Simulations are conducted for the native form of sperm whale myoglobin and for two other mutants, V68W and L29F, illustrating a fair diversity of spatial and temporal geminate recombination processes. Energy flow to the heme and immediate protein environment …
Inter and intra-guild interactions in egg parasitoid species of the soybean stink bug complex
2002
Abstract – The objective of this research was to evaluate the parasitism behavior of Telenomus podisiAshmead, Trissolcus basalis (Wollaston) e Trissolcus urichi Crawford (Hymenoptera: Scelionidae) oneggs of Nezara viridula L., Euschistus heros F., Piezodorus guildinii Westwood and Acrosternumaseadum Rolston (Heteroptera: Pentatomidae), in no choice and multiple choice experiments. For allparasitoid species, the results demonstrated the existence of a main host species that maximizes thereproductive success. The competitive interactions among the parasitoid species were investigated inexperiments of sequential and simultaneous release of different combinations of parasitoid pairs on thehosts…
"Successful and feminine athlete" and "natural-born fighter" : a discursive exploration of female judoka's identities in Greece and Finland
2018
Despite feminist concerns about the asymmetrical distribution of power in martial arts and combat sports (MACS), sport psychology research has overlooked issues of inequality and socio-cultural difference, as well as their effects on athletes’ experiences and identity negotiation. The present doctoral dissertation explores the intersection of gender, culture, and identity in judo through the lens of cultural praxis and feminist poststructuralist frameworks. The aim was to explore in what ways the cultural context shapes the experiences and identities of female judoka (judo athletes). Two specific objectives were set: to trace the discourses (systems of knowledge) through which female judoka…
La combustione HCCI mediante miscele di gas naturale e benzina: una prima esperienza sperimentale
2016
Si presentano in questo articolo i risultati di una sperimentazione volta a valutare la possibilità di effettuare una combustione HCCI (Homogeneous Charge Compression Ignition) stabile mediante l’impiego di miscele di gas naturale (GN) e benzina. La combustione HCCI ha ottime prerogative di basso impatto ambientale, ma la sua realizzazione pone qualche problema di stabilità al variare delle condizioni di carico richieste al motore: lo studio condotto mostra come l’impiego di miscele di GN e benzina, la cui composizione permette di variarne la resistenza all’autoaccensione, consente di ampliare il campo di funzionamento stabile della combustione HCCI. In the last decade the HCCI combustion h…
A New Simple Function for Combustion and Cyclic Variation Modeling in Supercharged Spark Ignition Engines
2022
Research in the field of Internal Combustion (IC) engines focuses on the drastic reduction of both pollutant and greenhouse gas emissions. A promising alternative to gasoline and diesel fuel is represented by the use of gaseous fuels, above all green hydrogen but also Natural Gas (NG). In previous works, the authors investigated the performance, efficiency, and emissions of a supercharged Spark Ignition (SI) engine fueled with mixtures of gasoline and natural gas; a detailed research involving the combustion process of this kind of fuel mixture has been previously performed and a lot of experimental data have been collected. Combustion modeling is a fundamental tool in the design and optimi…
