Intraperitoneal adhesions-an ongoing challenge between biomedical engineering and the life sciences

2011

Peritoneal adhesions remain a relevant clinical problem despite the currently available prophylactic barrier materials. So far, the physical separation of traumatized serosa areas using barriers represents the most important clinical strategy for adhesion prevention. However, the optimal material has not yet been found. Further optimization or pharmacological functionalization of these barriers could give an innovative input for peritoneal adhesion prevention. Therefore, a more complete understanding of pathogenesis is required. On the basis of the pathophysiology of adhesion formation the main barriers currently in clinical practice as well as new innovations are discussed in the present r…

Probiotics. Going on the natural way.

2011

Science is providing us the tools to diagnose and treat the infection before it causes damage. For some decades now, bacteria known as probiotics have been added to various foods because of their beneficial effects for human health. It comprises knowledge of the relationship between diet and health and the effects of food ingredients on physiological functions and health. Probiotics are commonly consumed as part of fermented foods with specially added active live cultures; such as in yogurt or as dietary supplements. The potential application of probiotics for oral health has recently been the focus of attention for various health researchers. The number of products containing probiotics en…

Topical Fluoride for Preventing Dental Caries in Children and Adolescents

2012

The use of topically applied fluoride has been widely researched as a means to reduce the risk of dental caries in conjunction with other treatment modalities (mechanical oral hygiene, dietary control, antimicrobial intervention, pit and fissure sealants). There is overwhelming evidence that reports not only the significance and importance of the use of fluoride as a caries-preventive agent, but also how safe fluoride application is when used appropriately, particularly in higher risk individuals and populations. This paper reviews the caries-protective benefits of topical fluoride application in children and adolescents, with an emphasis on the clinical efficacy and safety of the vehicles …

Anonimo, De Cavichiolo, edizione critica, traduzione e commento a cura di Armando Bisanti

2013

Il «De Cavichiolo», breve testo dialogico in 76 distici elegiaci, incentrato sull’alterco fra una moglie insoddisfatta e un marito sodomita, ha posto delicati e controversi problemi agli studiosi che se ne sono occupati. Le questioni principali, strettamente correlate e interdipendenti, riguardano la cronologia della "pièce" (con ipotesi oscillanti fra il XII-XIII e il XV secolo) e i rapporti fra essa e la novella boccacciana di Pietro di Vinciolo (Decam. V, 10). L’edizione del «De Cavichiolo» che qui si propone è fondata sulla "recensio" di tutti e sette i manoscritti noti dell’opera. Nell’introduzione sono presentati la trama, il contenuto, i temi e i personaggi del «De Cavichiolo», viene…

The Inflammatory Feed-Forward Loop Triggered by the Complement Component C3 as a Potential Target in Endometriosis

2021

Copyright © 2021 Agostinis, Zorzet, Balduit, Zito, Mangogna, Macor, Romano, Toffoli, Belmonte, Morello, Martorana, Borelli, Ricci, Kishore and Bulla. The complement system is a major component of humoral innate immunity, acting as a first line of defense against microbes via opsonization and lysis of pathogens. However, novel roles of the complement system in inflammatory and immunological processes, including in cancer, are emerging. Endometriosis (EM), a benign disease characterized by ectopic endometrial implants, shows certain unique features of cancer, such as the capacity to invade surrounding tissues, and in severe cases, metastatic properties. A defective immune surveillance against…

Characterizing Cavities in Model Inclusion Fullerenes: A Comparative Study

2001

Abstract: The fullerene-82 cavity is selected as a model system in order to test several methods for characterizing inclusion molecules. The methods are based on different technical foundations such as a square and triangular tessellation of the molecular surface, spherical tessellation of the molecular surface, numerical integration of the atomic volumes and surfaces, triangular tessellation of the molecular surface, and cubic lattice approach to the molecular volume. Accurate measures of the molecular volume and surface area have been performed with the pseudorandom Monte Carlo (MCVS) and uniform Monte Carlo (UMCVS) methods. These calculations serve as a reference for the rest of the meth…

Description of a new species: Dorylaimus parasiticus , a parasite of amphibians in the Iberian Peninsula (Nematoda: Dorylaimida)

1995

Dorylaimus parasiticussp. nov. (Nematoda: Dorylaimidae) si described from the digestive tract and general body cavity of Salamandra salamandra, Rana perezi, and Bufo bufo, amphibians of the Iberian Peninsula (Spain). This is the first record of a member of the Order Dorylaimida size, a thick transversely striated body cuticle with 20 to 26 longitudinal ridges.

The determination of the initial straight length in root canals of mandibular premolars--an in vitro study.

2009

Abstract The aim of the present roentgenographic in vitro study was to determine the initial straight length from the cemento-enamel junction (CEJ) to the appearance of a root canal curvature in human mandibular premolars. A total number of 282 mandibular premolars were examined. Exclusion criteria comprised root caries, extensive restorations and endodontically treated teeth. The teeth were fixed and digitally radiographed by means of a specially developed fixation device with standardized and reproducible distances with the parallel technique (Heliodent MD; Merlin 2.1). The distances from the CEJ to the first curvature (> 5°) (distance I), from the first curvature to a second curvature (d…

Nano-sized I12L6 Molecular Capsules Based on the [N⋅⋅⋅I+⋅⋅⋅N] Halogen Bond

2017

Summary Self-assembly of pre-organized subunits with a concave overall shape is an effective strategy for the synthesis of supramolecular capsules. We report the synthesis of a cavitand-based hexameric capsule held together solely by 12 robust [N⋅⋅⋅I + ⋅⋅⋅N] halogen bonds and its characterization in solution and in the gas phase via 1 H NMR spectroscopy, diffusion-ordered nuclear magnetic resonance spectroscopy (DOSY), and electrospray ionization mass spectrometry. The [N⋅⋅⋅I + ⋅⋅⋅N] halogen-bonded hexameric capsule was efficiently synthesized from the isolobal metallosupramolecular Ag + capsule by application of the [N⋅⋅⋅Ag + ⋅⋅⋅N] → [N⋅⋅⋅I + ⋅⋅⋅N] cation-exchange reaction.
