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 Instrumentation for Astronomy V, Suzanne K.

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 è stato il trattamento aferetico maggiormente utilizzato (5 IADS, 2 Non-selettivi). In tutti i pazienti l’inibizione della produzione anticorpale è stata ottenuta mediante somministrazione perioperatoria di tacrolimus, micofenolato mofetil e prednisone associata a rituximab in 6 casi. L’induzione con basiliximab è 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 è rivelato efficace nella prevenzione del AAMR nonostante l’utilizzo selettivo dello IADS nel post-operatorio. Conclusioni: L’impiego 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
