Nell'articolo si presenta una nuova lettura del più antico tra gli epitaffi del sepolcro ferentiense dei Salvii (ILLRP, 589), conosciuto sin dal 1921 e largamente entrato nella bibliografia. Dalla revisione critica del testo si guadagna, tra l'altro, una messa a punto dei dati calendariali contenuti nell'epigrafe, donde la necessità di emendare una precedente integrazione del nome di mese etrusco Chosfer. Inoltre, la possibilità di riconoscere nella formula onomastica del sepolto il cognomen Crispus, consente alcune precisazioni sulla genealogia dei tre magistrati della tomba ; da ciò, e dal riesame dei dati archeologici emersi durante lo scavo, la possibilità di indicare una più verosimile cronologia delle sepolture di Aulo Salvio Crispino e Sesto Salvio, i cui epitaffi sono privi della data consolare.Emiliozzi Adriana.

Subdermal liposuction
No full textLiposuction is a widely used technique today and indications are that it is becoming even more popular due to new technical refinements. The use of cannulae with a smaller diameter allows suction of the fat immediately under the dermis. The cannula we use to perform this new kind of fat suction is straight and has an external diameter of less than 2 mm. This cannula, the so-called Mercedes cannula, has a bullet tip and a three-hole head. Moreover, the holes are not round but are slit-shaped and oriented in the same plane at 120 degrees. This cannula is specifically designed to produce less trauma. The cannula with one downward-facing orifice is not suitable for suction of the subdermal layer and an upward-facing orifice would be too traumatic. The advantage of this new technique, apart from the possibility of treating patients with very slight adiposity, is to allow an effective skin retraction. When a large amount of fat has already been aspirated, residual deformities can occur. These skin irregularities represent the lack of an effective cutaneous retraction mostly due to the permanence of the subdermal fat. In fact, the presence of a thick subdermal adipose layer decreases the possibility of skin retraction. Therefore, indications for liposuction of the subdermal fat are mainly the slight adiposities and the remnant deformities of a previous liposuction operation. Moreover, this technique is applied to every lipoplasty whenever better skin retraction is needed
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
