Agadirius trojani gen. et sp. nov.: a new owlfly (Neuroptera: Ascalaphidae) from Morocco

A new owlfly, Agadirius trojani gen. et sp. nov., (Ascalaphidae: Ascalaphinae), is described from the Anti-Atlas Mountains, Morocco. The habitus is unmistakable and differs from all other owlflies, but shares some superficial features with the genus Puer Lef?bvre, 1842. Agadirius gen. nov., belongs to the subfamily Ascalaphinae (split eyed owlflies) and has genitalia consistent with the tribe Ascalaphini as defined by Tjeder and Hansson (1992)

The Larvae of European Ascalaphidae (Neuroptera)

The larvae of all the European genera of Ascalaphidae are compared for the first time, highlighting the differential characters for identification purposes. The larva of the genus Ascalaphus is described for the first time while those of Puer, Bubopsis and Deleproctophylla are deeply revised. Actually, the larvae of Ascalaphus festivus (Rambur), Puer maculatus (Olivier), Bubopsis agrionoides (Rambur), Deleproctophylla australis (Rambur), Libelloides latinus (Lefebvre), Libelloides corsicus (Rambur) and Libelloides siculus (Angelini) are described or accurately depicted for the first time. The known larvae of the genus Libelloides are reviewed

Myrmeleon punicanus n.sp., a new pit-building antlion (Neuroptera Myrmeleontidae) from Sicily and Pantelleria

A new species of antlion, Myrmeleon punicanus n. sp. (Neuroptera Myrmeleontidae), is described from Sicily and Pantelleria. The new taxon belongs to the formicarius-group thanks to the absence of pilula axillaris in the male hind wings, the characteristics of the male genitalia and the ecological traits. Moreover, the validity of the new species is confirmed by a DNA based phylogenetic reconstruction in which it is compared with closely related taxa. A preliminary description of the third instar larva of M. punicanus n. sp. is also given. Its habitat is the Mediterranean shrub land in which the larvae build pit-traps near shelters. Due to its ecological requirements a possible endangered status cannot be ruled out because of the anthropogenic habitat fragmentation

The stochastic digital human is now enrolling for in silico imaging trials -- Methods and tools for generating digital cohorts

Randomized clinical trials, while often viewed as the highest evidentiary bar by which to judge the quality of a medical intervention, are far from perfect. In silico imaging trials are computational studies that seek to ascertain the performance of a medical device by collecting this information entirely via computer simulations. The benefits of in silico trials for evaluating new technology include significant resource and time savings, minimization of subject risk, the ability to study devices that are not achievable in the physical world, allow for the rapid and effective investigation of new technologies and ensure representation from all relevant subgroups. To conduct in silico trials, digital representations of humans are needed. We review the latest developments in methods and tools for obtaining digital humans for in silico imaging studies. First, we introduce terminology and a classification of digital human models. Second, we survey available methodologies for generating digital humans with healthy and diseased status and examine briefly the role of augmentation methods. Finally, we discuss the trade-offs of four approaches for sampling digital cohorts and the associated potential for study bias with selecting specific patient distributions

peer reviewedIn view of the European Association of Echocardiography (EAE) mission statement “To promote excellence in clinical diagnosis, research, technical development, and education in cardiovascular ultrasound in Europe” and the increasing demand for standardization and quality control, the EAE have established recommendations and guidelines for standardization of echocardiography performance, data acquisition (images, measurements and morphologic descriptors), digital storage and reporting of echocardiographic studies. The aim of these recommendations is to provide a European consensus document on the minimum acceptable requirements for the clinical practice of echocardiography today and thus improve the quality and consistency of echocardiographic practice in Europe

Review of Antlions (Insecta: Neuroptera: Myrmeleontidae) in North Macedonia

We present the state of knowledge on the family Myrmeleontidae occurring in North Macedonia based on published records, museum specimens and new samples, and provide a comprehensive species list. North Macedonia represents only 3.9% of the area of the Balkan Peninsula but harbours 19 species belonging to 14 antlion genera, i.e., 61% of the peninsular fauna. We report collection localities, literature records and biological data for each species. Three species, Nemoleon poecilopterus, Neuroleon assimilis and Myrmeleon inconspicuus, are reported for the first time in North Macedonia. The genus Nemoleon Navás is also reported for the first time in the country

Detección del virus papiloma humano (HPV) y citología de Papanicolaou en mujeres de bajos recursos de la ciudad de Posadas, Misiones, Argentina

El objetivo de este estudio fue determinar la prevalencia de la infección por HPV y de lesiones cervicales en mujeres asistidas en un centro de salud situado en un área de bajos recursos de la ciudad de Posadas, Misiones, Argentina. Las muestras (n = 163) fueron examinadas mediante las pruebas de Papanicolaou y de PCR para HPV. Los factores socio-culturales de riesgo fueron identifcados mediante el cálculo de la odds ratio (OR, IC 95 %). Se detectaron lesiones cervicales en el 14,7 % de las mujeres. La prevalencia de infección por HPV fue de 38 %. Los tipos más frecuentes en la población total fueron HPV-16 (9,8 %) y HPV-33 (9,3 %). El HPV-16 se detectó asociado al 29,2 % y al 6,5 % de las mujeres con lesiones del cuello uterino y sin ellas, respectivamente, con un OR de 5,3 (1,8-15,8). Los factores de riesgo para la infección por HPV-16 fueron el hábito de fumar y el antecedente de enfermedades de transmisión sexual. Estos datos son importantes para la ejecución de los programas de prevención, incluyendo una introducción adecuada de la vacunación y la línea de base para la vigilancia virológica en la era de la vacuna.The objective of this study was to determine the prevalence of HPV infection and cervical lesions present in women who attended a health center in a low-resource area of the city of Posadas, Misiones, Argentina. Cervical cell samples (n = 163) were processed for Papanicolaou cytology and HPV-PCR tests. Socio-cultural risk factors were estimated using the odds ratio (OR, CI 95 %). Cervical lesions were detected in 14.7 % of women. The general prevalence of HPV infection was of 38 %. The most common types among the total population were HPV-16 (9.8 %) and HPV-33 (9.3 %). HPV-16 was detected in association with 29.2 % and 6.5 % of women with and without cervical lesions, respectively, the OR being 5.3 (1.8-15.8). Risk factors for HPV-16 infection were a smoking habit and a history of previous sexually-transmitted diseases. These data are important for the implementation of prevention programs, including an appropriate introduction of vaccination and the baseline for virological surveillance in the vaccine era.Fil: Badano, Ines.

Synchrotrons for hadron therapy, part 1

The treatment of cancer with accelerator beams has a long history with linacs, cyclotrons and now synchrotrons being exploited for this purpose. Treatment techniques can be broadly divided into the use of spread-out beams and scanned 'pencil' beams. The Bragg-peak behaviour of hadrons makes them ideal candidates for the latter. The combination of precisely focused 'pencil' beams with controllable penetration (Bragg peak) and high, radio-biological efficiency (light ions) opens the way to treating the more awkward tumours that are radio-resistant, complex in shape and lodged against critical organs. To accelerate light ions (probably carbon) with pulse-to-pulse energy variation, a synchrotron is the natural choice. The beam scanning system is controlled via an on-line measurement of the particle flux entering the patient and, for this reason, the beam spill must be extended in time (seconds) by a slow-extraction scheme. The quality of the dose intensity profile ultimately depends on the uniformity of the beam spill. This is the greatest challenge for the synchrotron, since slow-extraction schemes are notoriously sensitive. This paper reviews the extraction techniques, describes methods for smoothing the beam spill and outlines the implications for the extraction line and beam delivery system

Proton-Ion Medical Machine Study (PIMMS), 1

The Proton-Ion Medical Machine Study (PIMMS) group was formed following an agreement between the Med-AUSTRON (Austria) and the TERA Foundation (Italy) to combine their efforts in the design of a cancer therapy synchrotron. CERN agreed to host this study in its PS Division and a close collaboration was set up with GSI (Germany). The study group was later joined by Onkologie-2000 (Czech Republic). Effort was first focused on the theoretical understanding of slow extraction and the techniques required to produce a smooth beam spill for the conformal treatment of complex-shaped tumours with a sub-millimetre accuracy by active scanning with proton and carbon ion beams. Considerations for passive scanning were also included. The more general and theoretical aspects of the study are recorded in Part I and the more specific technical design considerations are presented in a second volume Part II. The PIMMS team started their work in January 1996 in the PS Division and continued for a period of three years

A global assessment of the potential distribution of naturalized and planted populations of the ornamental alien tree Schinus molle

Estudio sobre la potencial invasión del pirul, una planta naturalizada cuyo origen es el sur de América.The Peruvian Peppertree (Schinus molle L.) is an evergreen tree native to semiarid environments of Peru and Bolivia in South America. This tree has been introduced and widely planted for ornamental and forestry purposes in several semiarid regions of the world because its seedlings are easily established and have a high survival rate; it also grows quickly, and it is tolerant of dry climates. We compared the global and regional niches of naturalized and planted populations of S. molle in order to examine the invasive stages and potential distribution of this species in four regions of the world. This work provides a novel approach for understanding the invasion dynamics of S. molle in these areas and elucidates the ecological processes that bring about such invasions. Most naturalized and planted populations were found to be in equilibrium with the environment. In its native range as well as in Australia and South Africa the models of the coverage area of habitat suitability for natural populations were the highest, whereas the coverage area of planted populations was lower. For planted populations in Australia and South Africa, a large percentage of predicted presences fell within sink populations. The invasion stages of S. molle vary across regions in its adventive range; this result may be attributable to residence time as well as climatic and anthropic factors that have contributed to the spread of populations.SEMARNAT-CONACYT [Grant FSSEMARNAT01-C-2018-1-A3-S-80837]
