Trattamento ortopedico con corsetto
Conservative treatment of scoliosis by orthopaedic brace has an indication in cases of moderate or mild scoliosis. Its efficacy is demonstrated through the experience of several orthopaedic schools. The indication to adopt an orthopaedic brace is given by: curve degrees and its correggibility, skeletal age of patients and cosmetical aspect. The choice of the appropriate brace depends on kind and degrees of the curve. We examine technical characteristics of the most common braces (Milwaukee, Lyonnais, La Padula) and their us
New insights on Troglophilus (Orthoptera Rhaphidophoridae) species distribution in the westernmost area of their main range (Northern Italy)
The genus TroglophilusKrauss includes species with a rather limited dispersal ability and a wide distribution range, making it a good model for biogeographic, phylogeographic and phylogenetic investigations, with growing interest in recent years. However, a crucial prerequisite for addressing biogeographic issues is the knowledge about species complete distribution range. In particu-lar, Troglophilus cavicola(Kollar) and Troglophilus neglectusKrauss are the species of the genus Troglophiluswith the widest distribution in Europe, where their main areal extends westward to Northern Italy, but their precise distribution and range limits are still uncertain. In this study, the presence of these two species, which overwinter in hypogean habitats, was investigated in caves of the westernmost area of Northern Italy (Lombardy, Provinces of Lecco and Como) where populations belonging to the genus Troglophiluswere reported. The individuals of these populations were described by previous literature as T. cavicolaor as Troglophilussp. without species determination. In this work, an in situ morphological identification of all individuals detected in the surveyed caves, and a molecular identification on 12 specimens through the COI barcoding, were performed. An effective, fast, simple, economical and easily reproducible protocol for DNA extraction was optimized for this taxon. The presence ofT. cavicolain the investigated area was confirmed and the presence of T. neglectuswas reported for the first time. These new data allowed us to hypothesize different scenarios about their dispersal route in Lombardy. Moreover, these new findings must be con-sidered to define sampling plans to elucidate the biogeography of this genus
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
ALKYLATION OF AROMATIC-COMPOUNDS WITH OPTICALLY-ACTIVE LACTIC-ACID DERIVATIVES - SYNTHESIS OF OPTICALLY PURE 2-ARYLPROPIONIC ACID AND ESTERS
The alkylation of benzene with @)-methyl
2-[ (chlorosulfonyl)oxy]- or 2-(mesyloxy)propionate, in the
presence of aluminum chloride, affords (S)-methyl 2-phenylpropionate in good chemical (5040%) and excellent optical yield (197% as determined by rotation), with inversion of configuration at the attacking carbon atom
Strategie nel trattamento conservativo del piede torto congenito
Clubfoot is one of the most common congenital abnormalities and,
therefore, only a proper and early treatment can avoid a permanent
deformity.
Since clubfoot can determine many different clinical patterns, conservative treatment includes several strategies in order to face this
pathology timely, such as Ponseti’s method and the French functional
method. A review of the latest international literature about the
comparison between these two methods allows to state that the choice of one or the other must vary following the severity of the deformity, the social and economic context of the patient’s family but, mainly, the specific problems of each individual patient, who will have to undergo a long follow-up period in order to check the good
outcome of the treatment and to avoid relapses
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
