Abstract: El riesgo de leishmaniasis visceral (LV) urbana epidémica se registró por primera vez en la Argentina en el a o 2004, por presencia del vector Lutzomyia longipalpis en la provincia de Formosa, la provincia de Misiones registra casos de LV humana, LV canina y vector en el a o 2006, y la provincia de Corrientes en el verano 2008-2009. En la provincia de Santiago del Estero los casos de LV humana y LV canina en el a o 2008 estuvieron asociados posiblemente a vectores secundarios. Por ello, para conocer la distribución del riesgo en la región del Chaco, entre enero y abril del 2010 se realizó la búsqueda sistemática del vector de LV en 30 localidades de las provincias de Formosa, Chaco y en la ciudad de Reconquista, Santa Fe (224 trampas/noche). Se comprobó la presencia de Lu. longipalpis, por primera vez, en las localidades de Resistencia y Puerto Antequera (Chaco). En Clorinda y Puerto Pilcomayo (Formosa) se obtuvieron las trampas con más ejemplares, 158 y 241 Lu. longipalpis trampa/sitio/noche respectivamente. Los resultados muestran que el vector de la LV urbana epidémica continúa dispersándose en el territorio argentino, habiendo ingresado a la provincia de Chaco. La notificación de casos esporádicos en la región chaque a, transmitidos por vectores secundarios, como Lu. migonei, podría aumentar también debido a la vigilancia intensificada, y a la dispersión del parásito asociada al tránsito de perros infectados, sintomáticos o asintomáticos. The appearance of the vector of visceral leishmaniasis (VL) Lutzomyia longipalpis in the province of Formosa in 2004 was associated with urban epidemic risk for the first time in Argentina. During 2006, vectors, canine and human cases of VL were reported in the province of Misiones, and in summer 2008-2009, in the province of Corrientes. In Santiago del Estero province in 2008, cases of human and canine VL were associated with secondary vectors. Therefore, with the aim to know the current distribution of VL risk in the Chaco region, systematic captures of the vector were performed between January and April 2010 in 30 localities of Formosa and Chaco, and in the city of Reconquista, province of Santa Fe (224 traps/night). Lu. longipalpis was reported for the first time in the cities of Resistencia and Puerto Antequera (Chaco). Clorinda and Puerto Pilcomayo (Formosa) are the localities where the traps with more individuals were obtained, 158 and 241 Lu. longipalpis trap / site / night respectively. These results showed that the vector of urban epidemic VL is still spreading in Argentina, and already reached the provin

Abstract: the appearance of the vector of visceral leishmaniasis (vl) lutzomyia longipalpis in the province of formosa in 2004 was associated with urban epidemic risk for the first time in argentina. during 2006, vectors, canine and human cases of vl were reported in the province of misiones, and in summer 2008-2009, in the province of corrientes. in santiago del estero province in 2008, cases of human and canine vl were associated with secondary vectors. therefore, with the aim to know the current distribution of vl risk in the chaco region, systematic captures of the vector were performed between january and april 2010 in 30 localities of formosa and chaco, and in the city of reconquista, province of santa fe (224 traps/night). lu. longipalpis was reported for the first time in the cities of resistencia and puerto antequera (chaco). clorinda and puerto pilcomayo (formosa) are the localities where the traps with more individuals were obtained, 158 and 241 lu. longipalpis trap / site / night respectively. these results showed that the vector of urban epidemic vl is still spreading in argentina, and already reached the province of chaco. sporadic cases reported in the chaco region, transmitted by secondary vectors as lu. migonei would also increase due to intensified surveillance, and the dispersion of the parasite associated with the transit of asymptomatic or symptomatic infected dogs.
Obstructive sleep apnea syndrome: relationships between severity and sex
Longo L,Rea A,Santimone R,Fabiani M
Prevention and Research : International Open Access Journal of Prevention and Research in Medicine , 2012, DOI: 10.7362/2240-2594.086.2012
Abstract: Background: Obstructive sleep apnea syndrome (OSAS) is a pathological condition characterized by frequent episodes of collapse of the structures of the upper airways with interruption of airflow and reduction of oxygen saturation in arterial blood.Its incidence is equal to about 4% in men and 2% in females in the population up to 65 years of age.The severity of OSAS is determined by an index that relates the number of apneic events per hour of sleep "apnea-hypopnea index" (in English AHI: apnea-hypopnea index).As the muscle tone of the body ordinarily relaxes during sleep, and the airway at the throat is composed of walls of soft tissue, which can collapse, it is not surprising that breathing can be obstructed during sleep.Common signs of OSA are unexplained daytime sleepiness, restless sleep, and loud snoring (with periods of silence followed by gasps). Less common symptoms are morning headaches, insomnia, trouble concentrating, mood changes such as irritability, anxiety and depression, forgetfulness, increased heart rate and/or blood pressure, decreased sex drive, unexplained weight gain, increased urination and/or nocturia, frequent heartburn or gastroesophageal reflux disease, and heavy night sweats.The gold standard for the diagnosis of OSAS is considered the polysomnography. Objectives: The aim of our study is to evaluate the influence of sex in the presentation of the disease. Methods: The sample was undergone to a visit for the evaluation of any anatomical abnormalities of the first airways, which can cause or aggravate the disease.Patients was subjected to a questionnaire for the evaluation of disorders which achieve to disease with the compilation of the Epworth evaluation scale, which measure the frequency with which the patient tends to fall asleep during the daily activities.We utilized also the polysomnography for the diagnosis and staging of the disease. Results: The analysis of the results obtained allows us to observe that the ratio between the apnea/Hypopnea number for hour and sex is not statistically significant (p>0,05), despite the prevalence of OSAS is greater in males than in females, with a ratio of 3:1. Discussion and Conclusions: Our study has allowed us to observe that the frequency of submission of OSAS is greater in male than female with a ratio of 3:1, while the severity of the disease does not appear related to sex.Thus, our study confirms the existing data in the literature showing a ratio of 5:1 in the presentation of the disease in males than in females.
Experiencing a Problem-Based Learning Approach for Teaching Reconfigurable Architecture Design
Erwan Fabiani
International Journal of Reconfigurable Computing , 2009, DOI: 10.1155/2009/923415
Abstract: This paper presents the “reconfigurable computing” teaching part of a computer science master course (first year) on parallel architectures. The practical work sessions of this course rely on active pedagogy using problem-based learning, focused on designing a reconfigurable architecture for the implementation of an application class of image processing algorithms. We show how the successive steps of this project permit the student to experiment with several fundamental concepts of reconfigurable computing at different levels. Specific experiments include exploitation of architectural parallelism, dataflow and communicating component-based design, and configurability-specificity tradeoffs.
Sex Determination in the Near Threatened Guadalupe Fur Seal: Molecular Markers and Their Potential Applications  [PDF]
Simona Sanvito, Anna Fabiani, Filippo Galimberti
Open Journal of Animal Sciences (OJAS) , 2014, DOI: 10.4236/ojas.2014.45034
Abstract: The determination of sex by simple observation is often difficult in marine mammals, even in sexually dimorphic species. Moreover, there is often the practical necessity to determine sex in samples that have been collected without handling or observing the subjects. In these cases, a molecular assay for sex determination is required. We adapted an assay that targets the zinc-finger region and is based on a single primer pair, to the Guadalupe fur seal, a near threatened species that has a very limited breeding range. First, we validated the assay with a sample of pups in which we determined the sex by direct observation during handling; second, we compared it to a more recent assay, based on two different primer pairs and, finally, we evaluated the effect of DNA quantity on its reliability. The assay that we tested produced excellent results and was more reliable than the other one based on two primers. Reliable results were also obtained when only remarkably small quantities of DNA were amplified. These results show the potential use of this molecular assay in case of non-invasive sampling, an overly common situation when dealing with species of problematic conservation status.
Subclinical permanent hearing disorders in patients with sleep apnea
Fabiani M,Fabiani V,Rea A
Prevention and Research : International Open Access Journal of Prevention and Research in Medicine , 2012, DOI: 10.7362/2240-2594.027.2012
Abstract: Background: The obstructive sleep apnea syndrome is characterized by partial or complete obstruction of the upper airway and it affects 5% of the adult population. Repeated episodes of partial or total obstruction of the upper airway are responsible for the reduction in oxygen saturation in arterial blood (SaO2) and therefore hypoxia. The hypoxia is linked to a damage of the cochlear structures: vascular stria, afferent synapse, inner hair cells but also outer hair cells of the basal turn which appear to be the most vulnerable. Such damages are responsible for sensorineural hearing loss. Objectives: Aim of the study is to determine the correlation between cochlear damage and hypoxia through the Otoacoustic Emissions (TEOAE and DPOAE), to assess the influence of hypoxia on the hearing of patients with severe OSAS and to prevent the early damage may become permanent. Methods: 20 patients with severe obstructive sleep apnea syndrome (AHI> 30 events / hour of sleep) and 20 healthy subjects, non-snorers and clinically non-OSAS, underwent domiciliary polysomnographic examination, Transient Evoked OtoAcoustic Emissions (TEOAE ) and Distortion Product OtoAcoustic Emissions (DPOAE). Results: Compared to the control group (2 out of 20) OSAS patients (10 out of 20) have right ear DPOAE pathologies with a frequency of 3 kHz, 4 kHz: left ear DPOAE pathologies have only a frequency of 3 kHz.Finally the TEOAE in the right ear appear to be pathological at 2 kHz frequency in 9 out of 20 OSAS patients in the right ear and in 10 patients OSAS out of 20 at a frequency of 3 kHz. OSAS patients are pathological TEOAE in the left ear at frequencies of 2 and 3 kHz. Conclusions: The DPOAE and TEOAE are predictive of cochlear damage resulting from hypoxia before a sensorineural hearing loss can be measured by routine audiological tests.

Fast optical imaging of human brain function
Gabriele Gratton,Monica Fabiani
Frontiers in Human Neuroscience , 2010, DOI: 10.3389/fnhum.2010.00052
Abstract: Great advancements in brain imaging during the last few decades have opened a large number of new possibilities for neuroscientists. The most dominant methodologies (electrophysiological and magnetic resonance-based methods) emphasize temporal and spatial information, respectively. However, theorizing about brain function has recently emphasized the importance of rapid (within 100 ms or so) interactions between different elements of complex neuronal networks. Fast optical imaging, and in particular the event-related optical signal (EROS, a technology that has emerged over the last 15 years) may provide descriptions of localized (to sub-cm level) brain activity with a temporal resolution of less than 100 ms. The main limitations of EROS are its limited penetration, which allows us to image cortical structures not deeper than 3 cm from the surface of the head, and its low signal-to-noise ratio. Advantages include the fact that EROS is compatible with most other imaging methods, including electrophysiological, magnetic resonance, and trans-cranial magnetic stimulation techniques, with which can be recorded concurrently. In this paper we present a summary of the research that has been conducted so far on fast optical imaging, including evidence for the possibility of recording neuronal signals with this method, the properties of the signals, and various examples of applications to the study of human cognitive neuroscience. Extant issues, controversies, and possible future developments are also discussed.
