The Noncommutative Geometry of the Quantum Projective Plane

We study the spectral geometry of the quantum projective plane CP^2_q, a deformation of the complex projective plane CP^2, the simplest example of a spin^c manifold which is not spin. In particular, we construct a Dirac operator D which gives a 0^+ summable spectral triple, equivariant under U_q(su(3)). The square of D is a central element for which left and right actions on spinors coincide, a fact that is exploited to compute explicitly its spectrum.Comment: v2: 26 pages.

Correction of prominent ears with a new splinting technique

Correction of prominent ears represents one of the main applications in plastic surgery. Apart from its cosmetic nature, this operation is important because of the psychological distress that the deformity causes patients. In this study, 40 patients who underwent treatment for prominent ears in our department were evaluated. The classical surgical technique described by Chongchet followed by a new splinting procedure was performed. The advantages of this technique are described in comparison with traditional methods

Neodymium: Yttrium-Aluminum-Garnet Long Impulse Laser for the Elimination of Superfluous Hair: Experiences and Considerations from 3 Years of Activity

This study examined the results obtained with a modern apparatus for laser hair removal (neodymium: yttrium-aluminum-garnet [Nd:YAG] laser at long impulses with a wave-length of 1,064 nm; Q-switched laser) over a follow-up period of 3 years. A large heterogeneous group of 480 patients was taken into consideration. These patients were treated according to a standard protocol with monthly checkups and a personalized protocol at deferred appointments. The results, discovered by means of the most objective procedure possible, were retrieved and put into a graph showing two different curves for the repopulation of hair. In their clinical travels, the authors observed an average variable regrowth of 40% to 65%, allowing them to affirm that laser hair removal using Nd:YAG at long impulses is decisively efficient in obtaining long-term results. The use of a protocol (denominated "prolonged monthly checkup") with laser sessions at ever-decreasing periods permits, among other things, more outstanding and advantageous results for the patient. Thanks to more efficiently synchronized phases of the biologic hair cycle, this shortens and moves the telegenic phases closer and also renders the anagenic phases (those in which the selective photoermolysis on the pilipheric follicle proves to be efficient) more efficient. Personalization of the treatment relative to the monthly health checkup sessions is of fundamental importance to the scope of obtaining the best results in terms of cost-benefit rate, provided submassimal fluxes are (i.e., those well-tolerated by the patient) used. All this allows hair removal that is not definitive, but which becomes progressively permanent (i.e., characterized by ever-growing periods of lack of hair sustained by sporadic maintenance laser sessions based on the individual's necessity). © 2004 Springer Science+Business Media, Inc

New patents on topical anesthetics.

Anesthesia is defined as a total or partial loss of sensation and it may be general, local or topical, depending on the method of drug administration and area of the body affected. General anesthesia is a reversible state of unconsciousness produced by anesthetic agents, characterized by amnesia, muscle relaxation and loss of sensitivity to pain of the whole body. General anesthetic drugs can be classified into two main groups according to their predominant molecular pharmacological effects: volatile and intravenous agents. Local anesthesia produce a reversible loss of sensation in a portion of the body and it reversibly block impulse conduction along nerve axons and other excitable membrane. All local anesthetics (LA) are membrane stabilizing drugs; they reversibly decrease the rate of depolarization and repolarization of excitable membranes. They act mainly by inhibiting sodium influx through sodium-specific ion channels in the neuronal cell membrane, in particular the voltage-gated sodium channels. When the influx of sodium is interrupted, an action potential cannot arise and signal conduction is inhibited. The main local anesthetic (LA) agents for skin anesthesia are benzocaine (aminoester), prilocaine and lidocaine (aminoamides) which are commercially available as gels, ointments and creams (benzocaine and eutectic mixture of lidocaine and prilocaine) or as a bioadhesive (lidocaine) with different compositions (vehicles and excipients) for adults or pediatric use. Topical anesthetics decrease anxiety, pain and discomfort during cutaneous procedures and provide effective analgesia with rapid onset, prolonged duration and minimal side effects. This article outlines the different classes of topical anesthetics available and gives an overview of the mechanism of action, metabolism of each different class, of the possible complications that can occur because of their use and their possible treatment options and new patents. © 2014 Bentham Science Publishers

Interleukin-2-based therapy following surgery for renal cell carcinoma metastatic to the chest wall.

Herein, thè authors report two cases of renai celi carcinoma with solitary metastasis to thè chest wall. lnterleukin-2-based therapy following nephrectomy and resection of thè metastatic lesion of thè chest wall resulted in improvement of quality of life and in prolonged diseasefree survival in ali patients. They believe that an aggressive surgical approach, in selected patients with metastatic renai celi carcinoma, may improve patients' response to immunotherap
