Carotid intimal-media thickness and endothelial function in young patients with history of myocardial infarction
2009
AIM: The aim of the study was to evaluate the prevalence of carotid atherosclerosis and endothelial dysfunction in 45 young patients (38 mens and 7 females) with myocardial infarction (MI), age 29-45, mean age 42+/-3 years, to verify its possible role as a marker of coronary atherosclerosis. METHODS: Vascular echography was performed to verify the presence of carotid atherosclerosis and/or endothelial dysfunction in 45 young patients with MI and in 45 healthy control subjects well matched for age and sex. RESULTS: We observed a normal intima media thickness (IMT) only in 30% of patients with juvenile myocardial infarction (JMI) compared with 66% in the control group (P<0.0001) and 34% of pa…
Il campanile della Cattedrale di Palermo (1726-1729)
2021
Il contributo analizza la conformazione settecentesca del campanile della cattedrale di Palermo, nota attraverso documenti e sintetiche descrizioni, ma soprattutto grazie all'iconografia storica. La cella campanaria e la relativa terminazione a bulbo, nonché un recinto architettonico che alloggiava le campane minori, realizzati su progetto dell'architetto Giovanni Amico tra 1726 e 1729 (rimpiazzati da nuove strutture in forme neogotiche nel secondo quarto del XIX secolo), sono l'oggetto di una lettura critica che ha portato all'elaborazione di una ricostruzione virtuale attraverso un modello 3D.
Transportan 10 Induces Perturbation and Pores Formation in Giant Plasma Membrane Vesicles Derived from Cancer Liver Cells
2023
Continuous progress has been made in the development of new molecules for therapeutic purposes. This is driven by the need to address several challenges such as molecular instability and biocompatibility, difficulties in crossing the plasma membrane, and the development of host resistance. In this context, cell-penetrating peptides (CPPs) constitute a promising tool for the development of new therapies due to their intrinsic ability to deliver therapeutic molecules to cells and tissues. These short peptides have gained increasing attention for applications in drug delivery as well as for their antimicrobial and anticancer activity but the general rules regulating the events involved in cell…
Covalent modificaition of juvenile hormone binding proteins by photoaffinity labeling: An unexpected gel shift effect
1994
The 32 kD juvenile hormone binding protein (JHBP) and two 80 kD proteins in larval Manduca sexta hemolymph were labeled with [3H]FDK, a photoaffinity analog of methyl farnesoate (MF). The labeling could be completely displaced by a 30-fold excess of either MF or JH II, demonstrating that [3H]FDK binds specifically to the JH binding sites of the 32 kD JHBP and the 80 kD proteins. In addition, a high molecular-mass protein was labeled with [3H]FDK; labeling could be displaced by excess MF but not by JH II, demonstrating the selectivity in binding MF. The 32 kD JHBP also appeared to weakly bind the potent juvenoid, methoprene, at the JH binding site. Covalent modification by [3H]FDK induced a …
Micropropagation of bay laurel (Daphne gnidiumL.)
1996
SummaryProcedures have been developed for the micropropagation of Daphne gnidium, a shrub species of ecological interest, using explants of juvenile and adult origin. Shoot proliferation rates were significantly affected by both salt formulation and benzylade- nine concentration. Best results were obtained on WP medium with 5 µM BA. The presence of indoleacetic acid in the induction medium improved BA-induced axillary bud proliferation from juvenile explants. Rooting of shoots produced in culture was difficult, especially those of adult origin. Besides an absolute requirement for auxin, calcium concentration and the pH of the medium affected the formation of adventitious roots from regenera…
Micropropagation of juvenile and adult Sorbus domestica L.
1991
Successful propagation of seedlings and mature trees of Sorbus domestica L. has been achieved by in vitro methods. Multiple shoot formation was obtained by placing shoot apices or nodal segments on a modified Schenck and Hildebrandt medium containing benzyladenine. Regenerated shoots were excised and induced to root on media with auxin. In the best treatments 75–85% of shoots from juvenile material rooted. Rooting capacity of shoots from mature explants was lower (30%) and was not improved by dipping the base of shoots in concentration solutions of indolebutyric or naphthaleneacetic acids. Plantlets were ultimately established in soil.
Biological Activities of Natural Sesquiterpene Lactones and the Effect of Synthetic Sesquiterpene Derivatives on Insect Juvenile Hormone Biosynthesis
1998
Three natural sesquiterpene lactones have been assayed for their biological activity on locust (Locusta migratoria) nymphs. Since results obtained in vivo pointed to disruptions on juvenile hormone (JH)-regulated physiology, we tested the sesquiterpene lactones and a family of synthetic sesquiterpene derivatives for their ability to disturb the rate of JH biosynthesis by locust corpora allata (CA) in vitro. All the active compounds in vitro share a basic sesquiterpene double-ring structure as well as substituents with different chemical complexities. Compounds that shared an eudesmane base with different oxidation states on C3 and C12 carbon atoms were tested as JH biosynthesis inhibitors. …
Use of fluorescent dyes for developing latent lip prints
2004
Advances in the sensitivity of techniques used to examine latent prints (finger or labial) make it necessary to find more effective methods of locating prints on different surfaces. The most difficult surfaces are those which are porous or multicoloured, in which case the developed print may not be easily seen. This study analyses the effectiveness of two fluorescent dyes, Nile Blue and Nile Red, in developing both recent and older latent lip prints on porous and multicoloured surfaces. The results indicate that Nile Red is a very effective reagent for the development of latent lip prints on difficult surfaces of this type.
Child Abuse, Neglect, and Violent Criminal Behavior in a Midwest Metropolitan Area of the United States, 1967-1988
1991
These data examine the relationships between childhood abuse and/or neglect and later criminal and violent criminal behavior. In particular, the data focus on whether being a victim of violence and/or neglect in early childhood leads to being a criminal offender in adolescence or early adulthood and whether a relationship exists between childhood abuse or neglect and arrests as a juvenile, arrests as an adult, and arrests for violent offenses. For this data collection, adult and juvenile criminal histories of sampled cases with backgrounds of abuse or neglect were compared to those of a matched control group with no official record of abuse or neglect. Variables contained in Part 1 include …
Watersport and juvenile criminal justice: social projects for individual and community well-being
2023
Background:Intervention projects in social and psychological fields envisage actions aimed at creating a network not only among institutions and informal support but also an opportunity for the promotion of well-being, individuals and communities. Methods:This project was based on an active and individual-centered approach that involved in 2020, 6 young people from the Palermo Juvenile Prison, involving their awareness and participation in planned activities that involved the use of a water sport (snorkeling) to offer them an opportunity for change. Results:The adoption of watersport has been a successful methodology, as they are based on sharing standards, individual responsibility and mut…
