Allomorphy in the Italian Passato Remoto: A Distributed Morphology Analysis
( Andrea Calabrese ) 서강대학교 언어정보연구소 2012 언어와 정보 사회 Vol.18 No.-
Calabrese, Andrea (2012), "Allomorphy in the Italian Passato Remoto: A Distributed Morphology Analysis," Language & Information Society 18. Many Italian verbs display stem alternations with highly idiosyncratic vocalic and consonantal allomorphy in the paradigm of the simple past. Due to their complexity, these alternations are often used by linguists as evidence for models assuming rote memorization of stem alternants and endings (see the recent work by Maiden 2005, 2010 for example). In this paper, I will show that these alternations are characterized by basic regularities and that a rather simple analysis of them can be formulated in the framework of Distributed Morphology (DM) (Halle and Marantz 1993; Embick 2010; Embick and Marantz 2008). In particular, this analysis involves notions such as roots, Vocabulary Items and Readjustment Rules as predicted by DM. There is no evidence for memorized stem alternants. Instead, the allomorphy we see in the Italian Passato Remoto is readily accounted for by providing an appropriate morphosyntactic analysis of the forms and by deriving the irregular alternants from single underlying roots by means of Readjustment Rules. This paper also shows that it is crucial that the rules accounting for this allomorphy obey a strict definition of locality requiring linear adjacency. This explains why the presence of the Thematic Vowel prevents their application. In the irregular forms where these rules apply, the Thematic Vowel is removed by a special pruning rule. Crucially, Impoverishment removes a diacritic index associated with the application of this pruning rule in certain morphosyntactic contexts (in the 1st and 2nd pl., and 2ndsg.), thus the regular basic form of the root will appear in these contexts. Impoverishment in this case is motivated by a general Markedness principle that disfavors complex exponence in morphologically marked environments.
Superthin Flap Harvesting Procedure: Technical Note
Sara Calabrese,Marco Innocenti 대한성형외과학회 2022 Archives of Plastic Surgery Vol.49 No.6
The anterolateral thigh (ALT) flap has been extensively discussed in the literature as it allows for a wide variety and depth of tissues for complex wound coverage. Thanks to many cadaveric and angiographic studies of the subdermal plexus, it is to date ascertained that tailoring ALT thickness can be safely performed without compromising flap outcomes or causing additional morbidity. Recently, the authors applied and described a simpler, safer, and less time-consuming superthin ALT perforator (ALTP) free flap harvesting technique. The aim of this article is to show the versatility of the adipofascial flap harvested around the chosen perforators, which allowed us to safely expand the usage of ALTP superthin flaps.
One injection for a great projection: a quick and simple procedure for nipple reconstruction

Women attach great importance to the presence of a three-dimensional nipple upon completion of the breast reconstruction process. To meet patients' expectations, nipple-areolar complex reconstruction should achieve symmetry in position, size, shape, texture, and color, as well as minimizing donor-site morbidity. However, it is well known that regardless of the reconstructive technique, loss of nipple projection can be reasonably expected. We developed and evaluated a quick, simple, and innovative technique using injectable Integra Flowable Wound Matrix to increase nipple projection after reconstruction. Twenty breast cancer patients who underwent nipple reconstruction resulting in unsatisfactory projection were enrolled in our retrospective study. Nipple projection was measured at the time of surgery and after 6 and 12 months. A visual analogue scale was used to assess patients' satisfaction. Our technique yielded reliable results in terms of the long-lasting maintenance of nipple projection. This method is high-priced, but cost-effective, since one kit may suffice for three patients. Furthermore, our patients were very appreciative of this technique as a single-step, minimally invasive, painless procedure with no reported necessity of re-intervention.
Radial forearm free flap in a patient with an unusual radial artery variation: a case report
Giulio Menichini,Sara Calabrese,Nicola Alfonsi,Marco Innocenti 대한성형외과학회 2021 Archives of Plastic Surgery Vol.48 No.6
Head and neck reconstruction poses unique challenges in rehabilitating surgical defects in terms of integrity, function, and form. The radial forearm free flap (RFFF) has been widely used for defect coverage, especially in the head and neck area, but its versatility allows it to be used for soft-tissue reconstruction in various parts of the body. The vascular features of the flap are quite constant and reliable. Nevertheless, abnormalities of the forearm vascular tree have been described over the decades. We report a case of intraoral reconstruction after verrucous carcinoma recurrence in a 74-year-old woman with an unusual forearm flap, which we called the median forearm free flap, based on a median branch of the radial artery that was preoperatively detected using handheld Doppler ultrasonography. The distally located skin paddle was predominantly supplied by the aberrant median vessel with its perforators. The flap was thus safely harvested with this atypical pedicle. Successful reconstruction of the intraoral defect was achieved, with an uneventful postoperative course.

Angelman syndrome (AS) is a severe neurobehavioural disorder caused by failure of expression of the maternal copy of the imprinted domain located on 15q11-q13. There are different mechanisms leading to AS: maternal microdeletion, uniparental disomy, defects in a putative imprinting centre, mutations of the E3 ubiquitin protein ligase (UBE3A) gene. However, some of suspected cases of AS are still scored negative to all the latter mutations. Recently, it has been shown that a proportion of negative cases bear large deletions overlapping one or more exons of the UBE3A gene. These deletions are difficult to detect by conventional gene-scanning methods due to the masking effect by the non-deleted allele. In this study, we have used for the first time multiplex ligation-dependent probe amplification (MLPA) and comparative multiplex dosage analysis (CMDA) to search for large deletions affecting the UBE3A gene. Using this approach, we identified a novel causative deletion involving exon 8 in an affected sibling. Based on our results, we propose the use of MLPA as a fast, accurate and inexpensive test to detect large deletions in the UBE3A gene in a small but significant percentage of AS patients.

Background: We performed a systematic review on the management of patellar fracture nonunion and report a novel suturebased non-metallic fixation technique associated with platelet-rich plasma and mesenchymal stem cell injections in the management of this injury. Methods: A systematic search was performed up to August 2020 in PubMed and Scopus electronic databases of scholarly articles evaluating different surgical techniques used for nonunion of patellar fractures, with no restrictions on language or year of publication. Furthermore, we describe our novel non-metallic suture fixation technique and a patient in whom this technique was applied. Results: A total of 9 articles were included in the systematic review. Tension band wiring was the most commonly used procedure (62.7%). Nonoperative procedures (8.1%) resulted in nonunion in all patients. The most common complication after open reduction and internal fixation was infection (7.8%). Our patient at the latest follow-up reported full functional recovery and full extension and flexion of the affected knee with no pain and subjectively normal strength. Conclusions: The management of patella nonunions is still a challenge. The technique reported here can be used in patellar fracture nonunion, as well as in primary patellar fractures.

A stable initiator for ROMP reactions, suitably designed to be embedded in structural resins, has been synthetized. It rapidly polymerizes cyclic olefins in reactive environments. The thermal stability and chemical inertness towards oxirane rings allow its employment in the form of molecular complex in epoxy precursors thus reducing the amount of initiator in structural self-healing materials of 90% wt/wt, simultaneously preserving the catalytic activity at high temperatures (180–200 C) also in presence of the aromatic primary amine (DDS). NMR and FTIR spectroscopy highlighted a relevant initiator stability able to fulfill industrial requirements. Self-healing efficiency has been found to be 103%.
