Analysis o f the daily locomotor activity of Acanthogonatus tacuariensis (Araneae, Nemesiidae)
The daily locomotor activity ofAcanthogonatus tacuariensis was investigated by means of an actograph apparatus. Twenty-one adult specimens (13 males and eight females) were monitored over 2,352 hours in the course of one year. The covariance analysis indicated neither significant statistical difference between specimens in the daily locomotor activity nor statistical difference between sexes. Statistical analysis of three variables was performed: duration of daily locomotor activity (hours), relation between hourly locomotor activity in darkness and in daylight and daily number of events occurring during the locomotor activity. Results suggest a possible association between daily mean temperature and the
studied variables.

Progress with the Prime Focus Spectrograph for the Subaru Telescope: a massively multiplexed optical and near-infrared fiber spectrograph
The Prime Focus Spectrograph (PFS) is an optical/near-infrared multi-fiber
spectrograph with 2394 science fibers, which are distributed in 1.3 degree
diameter field of view at Subaru 8.2-meter telescope. The simultaneous wide
wavelength coverage from 0.38 um to 1.26 um, with the resolving power of 3000,
strengthens its ability to target three main survey programs: cosmology,
Galactic archaeology, and galaxy/AGN evolution. A medium resolution mode with
resolving power of 5000 for 0.71 um to 0.89 um also will be available by simply
exchanging dispersers. PFS takes the role for the spectroscopic part of the
Subaru Measurement of Images and Redshifts project, while Hyper Suprime-Cam
works on the imaging part. To transform the telescope plus WFC focal ratio, a
3-mm thick broad-band coated glass-molded microlens is glued to each fiber tip.
A higher transmission fiber is selected for the longest part of cable system,
while one with a better FRD performance is selected for the fiber-positioner
and fiber-slit components, given the more frequent fiber movements and tightly
curved structure. Each Fiber positioner consists of two stages of
piezo-electric rotary motors. Its engineering model has been produced and
tested. Fiber positioning will be performed iteratively by taking an image of
artificially back-illuminated fibers with the Metrology camera located in the
Cassegrain container. The camera is carefully designed so that fiber position
measurements are unaffected by small amounts of high special-frequency
inaccuracies in WFC lens surface shapes. Target light carried through the fiber
system reaches one of four identical fast-Schmidt spectrograph modules, each
with three arms. Prototype VPH gratings have been optically tested. CCD
production is complete, with standard fully-depleted CCDs for red arms and
more-challenging thinner fully-depleted CCDs with blue-optimized coating for
blue arms.Comment: 14 pages, 12 figures, submitted to "Ground-based and Airborne

IL TRAPIANTO DI RENE DA VIVENTE ABO-INCOMPATIBILE: ANALISI DI 7 CASI
Introduzione: il trapianto ABO-incompatibile (txABOi) consente il superamento delle barriere
immunologiche tra donatore e ricevente con risultati sovrapponibili al trapianto ABO-compatibile.
Differenti protocolli di desensibilizzazione sono stati proposti per rimuovere gli anticorpi circolanti e
per inibire la loro produzione. Riportiamo la nostra esperienza relativa al txABOi effettuato
prevalentemente con immunoadsorbimento selettivo (IADS).
Materiali e metodi: abbiamo eseguito 7 txABOi utilizzando 6 coppie A vs O (3 A1, 3 A2) ed 1 B vs
O. Il titolo anticorpale iniziale variava da 1/512 ad 1/32 con target pre-operatorio 1/4. Lo IADS Ăš
stato il trattamento aferetico maggiormente utilizzato (5 IADS, 2 Non-selettivi). In tutti i pazienti
lâinibizione della produzione anticorpale Ăš stata ottenuta mediante somministrazione perioperatoria di
tacrolimus, micofenolato mofetil e prednisone associata a rituximab in 6 casi. Lâinduzione con
basiliximab Ăš stata effettuata in 6 pazienti, 2 sono stati sottoposti a IADS nel post-operatorio.
Risultati: in tutti i riceventi abbiamo ottenuto un titolo anticorpale pre-operatorio 1/4. Non si sono
verificati episodi di rigetto acuto anticorpo-mediato (AAMR). Ad un follow-up medio di 19.4 mesi
(3-49) tutti i grafts risultano funzionanti con una creatinina media di 1.3 mg/dL (0.9-1.9) ed un titolo
anticorpale compreso tra 1/2 ed 1/8.
Discussione: Il nostro protocollo di desensibilizzazione ha sempre consentito il raggiungimento del
target anticorpale pre-trapianto e si Ăš rivelato efficace nella prevenzione del AAMR nonostante
lâutilizzo selettivo dello IADS nel post-operatorio.
Conclusioni: Lâimpiego delle moderne tecniche aferetiche, in associazione agli attuali protocolli
immunodepressivi, rende il txABOi un atto terapeutico sicuro ed efficace
Role of telemedicine and smartphone for distant patient management in dentistry: The new way of triage
Telemedicine (TM) can be defined as the exchange of medical data through technology applications and devices,[1] opening door to different ways in diagnosing and in taking care at different levels and ages. This communication aimed to draw attention on the feasibility of technology applications in preliminary diagnosis
TRIGEMINAL TROPHIC SYNDROME: STRANGE EVOLUTION OF MAXILLOFACIAL SURGERY
Trigeminal trophic syndrome (TTS) is a rare facial/cranial affection that arises in ulcerations, itch and paresthesia. Etiology is debated, however trigeminal nerve damage seems to be frequent in pathogenetic patterns. The disease may affect any region innervated by the trigeminal nerve, especially the maxillary branch. A case of TTS, trigged by allergic reaction to osteosynthetic materials and involving infraorbital nerve, was presented. The feature that makes this case one-off in the literature is the association with osteolytic lesion surrounding infraorbital nerve. Diagnosis and treatment were difficult and multidisciplinary approach was required. Treatments administered were satisfying and signs and symptoms remitted, however patient quitted follow-up. TTS is a rare disease, diagnosis is difficult to be performed and it is often a diagnosis of exclusion. Treatment is challenging and it requires a multidisciplinary approach and a great compliance of patients
