Development of a Magnetoresistive-Based Wearable Eye-Tracking System for Oculomotor Assessment in Neurological and Otoneurological Research-Preliminary In Vivo Tests.

Over the past 20 years, several eye-tracking technologies have been developed. This article aims to present a new type of eye tracker capable of producing detailed information on eye and head movements using an array of magnetoresistive detectors fixed on the patient's head and a small magnet inserted into a contact lens, adapted to the curvature of the cornea of the subject. The software used for data analysis can combine or compare eye and head movements and can represent them as 2D or 3D images.

An innovative eye-tracker: Main features and demonstrative tests.

We present a set of results obtained with an innovative eye-tracker based on magnetic dipole localization by means of an array of magnetoresistive sensors. The system tracks both head and eye movements with a high rate (100-200 Sa/s) and in real time. A simple setup is arranged to simulate head and eye motions and to test the tracker performance under realistic conditions.

Recombinant human C1 esterase inhibitor for hereditary angioedema attacks: A European registry.

Background: Hereditary angioedema (HAE) due to C1 esterase inhibitor deficiency (C1-INH-HAE) is characterized by recurrent swelling attacks. A European treatment registry was established to review the adverse event profile and efficacy of recombinant human C1 esterase inhibitor (rhC1-INH) for HAE attacks.

Methods: Individuals with C1-INH-HAE were enrolled following a decision to treat with rhC1-INH and provision of written informed consent.

Bounds on Lorentz Invariance Violation from MAGIC Observation of GRB 190114C.

On January 14, 2019, the Major Atmospheric Gamma Imaging Cherenkov telescopes detected GRB 190114C above 0.2 TeV, recording the most energetic photons ever observed from a gamma-ray burst. We use this unique observation to probe an energy dependence of the speed of light in vacuo for photons as predicted by several quantum gravity models.

Functional leg length discrepancy between theories and reliable instrumental assessment: a study about newly invented NPoS system.

Background: In spite the instinct social&financial impact of Leg Length Discrepancy (LLD), controversial and conflicting results still exist regarding a reliable assessment/correction method. For proper management it's essential to discriminate between anatomical&functional Leg Length Discrepancy (FLLD). With the newly invented NPoS (New Postural Solution), under the umbrella of the collaboration of PRM Department, Tor Vergata University with Baro Postural Instruments srl, positive results were observed in both measuring& compensating the hemi-pelvic antero-medial rotation in FLLD through personalized bilateral heel raise using two NPoS components: Foot Image System (FIS) and Postural Optimizer System (POS).

Content validity of visual analog scales to assess symptom severity of acute angioedema attacks in adults with hereditary angioedema: an interview study.

Background: Hereditary angioedema (HAE) is a rare, debilitating, potentially life-threatening condition characterized by recurrent acute attacks of edema of the skin, face/upper airway, and gastrointestinal and urogenital tracts. During a laryngeal attack, people with HAE may be at risk of suffocation, while other attacks are often associated with intense pain, disfigurement, disability, and/or vomiting. The intensity of some symptoms is known only to the person experiencing them.

[Treatment of mucous and haemorrhoidal prolapse with circular stapler according to Longo: personal experience].

The authors present their experience with the treatment of haemorrhoidal prolapse using the Longo technique. From March 2005 to February 2006, 56 patients underwent the above-mentioned procedure, 49 of them (87.5%) suffering from third-degree and 7 (12.

Human placenta expresses endothelin gene and corresponding protein is excreted in urine in increasing amounts during normal pregnancy.

Systemic and renal hemodyanmic changes in normal pregnancy have been attributed in part to altered vascular synthesis of vasodilatory prostaglandins. Besides vasodilatory substances, endothelium also generates vasoconstrictors, including endothelin. We evaluated the capacity of placental tissue from normal pregnant women to express endothelin gene and to generate endothelin.

Increased renal endothelin production in rats with reduced renal mass.

Renal endothelin (ET) production was investigated in rats after renal mass ablation, a model of progressive renal disease characterized by glomerular hemodynamic alterations and capillary thrombosis, and in sham-operated animals. Thrombin stimulation of renal cortical tissue from rats with renal mass reduction, 45 but not 7 days after surgery, generated significantly (P less than 0.01) more ET than tissue from sham-operated animals.
