Abstract: Background: To date there is not a material considered ideal for the lased dentin. Objective: To compare the bond strength to human lased dentin of self-etch and etch-and-rinse adhesive systems, a self-adhesive resin composite and a glass-ionomer cement. Methods: Forty human molars were sectioned to obtain a 2 mm-thick slab of mid-coronal dentin. The occlusal surface of each slab was polished by SiC paper (P600) for 10 s. Then an half part of dentin slabs was randomly selected for receiving treatment with 2.94 μm Er:YAG laser (DEKA, Smart 2940D Plus) with 10 Hz at 100 mJ, pulse duration of 230 μs with contact tip. Dentin slabs were randomly divided into four groups (n = 10). Six conical frustum-shaped build-ups were constructed on the occlusal surface of each dentin slab using bonding agents (OptiBond Solo Plus Group 1; OptiBond All-in-one Group 2) combined with a resin composite (Premise Flow), self-adhesive resin composites (Vertise Flow Group 3) and a glass-ionomer cement (Ketac-Fil Group 4). Specimens were subjected to μSBS test. Data were analyzed by a mixed model and Tukey’s test. Results: Measured bond strengths were (mean ± standard deviation): 20.8 ± 5.5 MPa (laser treatment) and 15.6 ± 4.5 MPa (SiC paper) for Group 1, 18.9 ± 5.3 MPa (laser treatment) and 14.0 ± 4.3 MPa (SiC paper) for Group 2, 7.9 ± 2.8 MPa (laser treatment) and 4.3 ± 2.2 MPa (SiC paper) for Group 3, 4.7 ± 1.9 MPa (laser treatment) and 2.6 ± 1.2 MPa (SiC paper) for Group 4. The inferential analysis showed that the dentin laser treatment significantly affected the bond strength within each individual group. On dentin treated with laser the bond strengths recorded for build-ups constructed with etch and rinse and self-etch adhesive systems were significantly higher than those recorded for build-ups constructed with self-adhesive resin composite and glass-ionomer cement (p < 0.0001). Similarly, on dentin treated with SiC paper the bond strengths recorded for build-ups constructed with etch and rinse and self-etch adhesive systems were significantly higher than those recorded for build-ups constructed with self-adhesive resin composite and glass-ionomer cement (p < 0.0001). Conclusion: Er:YAG laser treatment has increased the shear bond strength of all the adhesive materials used.

A Survey on Just-Non- Groups
Daniele Ettore Otera,Francesco G. Russo
International Journal of Mathematics and Mathematical Sciences , 2010, DOI: 10.1155/2010/190830

Abstract: Let be a class of groups. A group which does not belong to but all of whose proper quotient groups belong to is called just-non- group. The present note is a survey of recent results on the topic with a special attention to topological groups. 1. The Interest in the Literature If is a class of groups, a group which belongs to is said to be an -group. A group is said to be a just-non- group, or briefly a JNX group, if it is not an -group but all of its proper quotients are -groups. By default, every simple group which is not an -group is a JNX group, so the simple groups constitute an easy source of examples for JNX groups. Their structure was studied for several choices of the class , so there is a well-developed theory about the topic. Some classic results can be found in [1–3] and recent contributions in [4–9]. Moreover the study of JNX groups has been investigated both in finite groups and infinite groups so that many techniques have general applications. Heineken's work [2] is typical for this line of research. In it a very special class of groups, namely, lagrangian groups, is treated. More recently, a team of authors treated in this fashion the class of Dedekind groups in [10]. H. Schunk was interested in studying JNX groups with respect to some problems of local theory of finite groups as [1, Chapter 3] exemplifies. JNX groups were called groups of boundary in the original works of H. Schunk and conditions of splitting were found (see [1, Chapters 6, 11]). Most of the time, the literature on JNX groups shows that their description overlaps the results of H. Schunk or a well-known splitting theorem of I. Schur and H. Zassenhaus (see [1, 18.1, 18.2]). Already in the context of locally finite groups, we may find generalizations, as described in [11, Chapter ]. Some variations can be adapted to the context of topological groups and we will list only two recent contributions. The first is in [5] and deals with JNL groups. Here a compact group is called a JNL group if it is not a Lie group, but all of its proper Hausdorff quotients are Lie groups. It is proved that a compact JNL group is profinite. This is another evidence that many techniques and methods have a general application in topics concerning JNX groups and that their topology is very special. We note that topological groups are treated in terms of classes and varieties of groups in [12–17], where restrictions, which are caused by the presence of topology, are investigated. The second contribution is in [9] (and also in [4] under a different prospective) and deals with a topological group

Subgroup S-commutativity degrees of finite groups
Daniele Ettore Otera,Francesco G. Russo
Mathematics , 2010,

Abstract: The so--called subgroup commutativity degree $sd(G)$ of a finite group $G$ is the number of permuting subgroups $(H,K) \in \mathrm{L}(G) \times \mathrm{L}(G)$, where $\mathrm{L}(G)$ is the subgroup lattice of $G$, divided by $|\mathrm{L}(G)|^2$. It allows us to measure how $G$ is far from the celebrated classification of quasihamiltonian groups of K. Iwasawa. Here we generalize $sd(G)$, looking at suitable sublattices of $\mathrm{L}(G)$, and show some new lower bounds.

On minimal non-$CL$-groups
Daniele Ettore Otera,Francesco G. Russo
Mathematics , 2010,

Abstract: If $m$ is a positive integer or infinity, the $m$-layer (or briefly, the layer) of a group $G$ is the subgroup $G_m$ generated by all elements of $G$ of order $m$. This notion goes back to some contributions of Ya.D. Polovickii of almost 60 years ago and is often investigated, because the presence of layers influences the group structure. If $G_m$ is finite for all $m$, $G$ is called $FL$-group (or $FO$-group). A generalization is given by $CL$-groups, that is, groups in which $G_m$ is a Chernikov group for all $m$. By working on the notion of $CL$-group instead of that of $FL$-group, we extend a recent result of Z. Zhang, describing the structure of a group which is not a $CL$-group, but whose proper subgroups are $CL$-groups.

Permutability degrees of finite groups
Daniele Ettore Otera,Francesco G. Russo
Mathematics , 2015,

Abstract: Given a finite group $G$, we introduce the \textit{permutability degree} of $G$, as $$pd(G)=\frac{1}{|G| \ |\mathcal{L}(G)|} {\underset{X \in \mathcal{L}(G)}\sum}|P_G(X)|,$$ where $\mathcal{L}(G)$ is the subgroup lattice of $G$ and $P_G(X)$ the permutizer of the subgroup $X$ in $G$, that is, the subgroup generated by all cyclic subgroups of $G$ that permute with $X\in \mathcal{L}(G)$. The number $pd(G)$ allows us to find some structural restrictions on $G$. Successively, we investigate the relations between $pd(G)$, the probability of commuting subgroups $sd(G)$ of $G$ and the probability of commuting elements $d(G)$ of $G$. Proving some inequalities between $pd(G)$, $sd(G)$ and $d(G)$, we correlate these notions.

The Pro.Bio.Dic. (Prototype of a Bioethics Dictionary) project: Building a corpus of popular and specialized bioethics texts
Grego, Kim,Russo, Daniele,Vicentini, Alessandra
- , 2013,

Abstract: Sa？etak This paper reports on an ongoing, long-term research project in the field of medical ethics and bioethics conducted by a multidisciplinary team combining medical, linguistic, IT and philosophical research interests: the Prototype of a Bioethics Dictionary (Pro.bio.dic). Having already outlined (Vicentini et al. 2011) the reasons and needs to both redefine and update the lexicographic material available so as to provide a corpus-based collection of the English terms of contemporary bioethics to be published on a web platform, the Pro.bio.dic has now entered the key stage of corpus-building. This stage requires establishing the criteria involved in creating a large, statistically-valid reference corpus of both specialized and popular bioethics texts, to be processed by means of text-mining and machine-learning techniques, and to serve as the basis from which the entries of the electronic online tool described as the Pro.bio.dic will be drawn by means of concordancing software

Atypical presentation and transabdominal treatment of chylothorax complicating esophagectomy for cancer
Matteo Rottoli, Iris S Russo, Daniele Bernardi, Luigi Bonavina
Journal of Cardiothoracic Surgery , 2012, DOI: 10.1186/1749-8090-7-9

Abstract: Chylotorax is a rare but potentially life-threatening complication of esophagectomy [1]. It occurs mostly after transthoracic esophagectomy and is often associated to pulmonary complications [2]. The daily amount and duration of chyle drainage dictate the need and timing for reoperative surgery. An initial trial of conservative treatment is often justified because it allows undisturbed healing of the esophagogastric anastomosis [3]. On the other hand, postponing a reoperation too late may lead to severe metabolic, immunologic, nutritional, and cardiorespiratory consequences. We report the case of a patient with postoperative chylotorax who presented with hemodynamic instability mimicking cardiac tamponade and was treated through a transhiatal approach after an unsuccessful attempt at conservative management.A 48 year old man was referred to our center with a 5 month history of dysphagia to solid food and weight loss. There was no significant comorbidity. The esophagogastroduodenoscopy showed an infiltrating tumor of the lower esophagus located between 33 and 38 cm from the incisors. Histopathologic examination revealed a poorly differentiated squamous cell carcinoma. Chest and abdominal computed tomography scan confirmed the presence of the esophageal lesion with enlarged mediastinal nodes and no evidence of distant metastases. The patient underwent neoadjuvant chemotherapy with carboplatin, paclitaxel, 5-fluorouracil, and 46 Gy radiotherapy. The re-staging after neoadjuvant treatment showed a partial response. The patient underwent a Ivor-Lewis esophagectomy with 2-field lymphadenectomy via laparoscopy and right thoracotomy. As usual, the thoracic duct was ligated en bloc with the azyos vein above the diaphragm. Pathological examination of the surgical specimen showed yT2-N1 disease and no evidence of margin infiltration.A high-volume serous fluid output (1100-1700 ml/day) from the right chest drain was noted since postoperative day 1. On postoperatively day 3 a le

Manifold benefits of choosing a minimally fluoroscopic catheter ablation approach
Michela Casella,Antonio Dello Russo,Gaetano Fassini,Daniele Andreini
World Journal of Cardiology , 2013, DOI: 10.4330/wjc.v5.i2.8

Abstract: We report the case of a 14-year-old boy with ventricular preexcitation. A standard, fluoroscopy guided, ablation procedure was successfully performed in a postero-midseptal region with a total fluoroscopy time of about 45 min (2430 cGy.cm2). A few hours after the procedure, preexcitation reappeared. A second ablation procedure was scheduled using the EnSite NavX mapping system. During mapping along the tricuspid groove, preexcitation suddenly disappeared due to mechanical “bumping” of the accessory pathway and it did not recover over the next 30 min. As per our routine practice, the phase of geometry reconstruction has been continuously recorded by the system; thus, an off-line analysis allowed to pinpoint the site of earliest activation and the site of mechanical bumping, where radiofrequency obtained the accessory pathway ablation. The second procedure was performed without using fluoroscopy at all. Thanks to the geometry reconstruction, the procedure was completely successful thus avoiding a further rehospitalization.
