A review of the current knowledge on Zeugodacus cucurbitae (Coquillett) (Diptera, Tephritidae) in Africa, with a list of species included in Zeugodacus
Published online 2015 Nov 26This paper reviews all available information regarding the occurrence and biology of the melon fly, Zeugodacus cucurbitae (Coquillett), in the Afrotropical Region, including data on invasion history, distribution patterns, population genetics, host range, and interspecific competition. Although limited intraspecific variability has been observed within the region regarding the above mentioned aspects, there seems to be no indication that Zeugodacus cucurbitae represents a species complex. A checklist of all of the species included in Zeugodacus as recently proposed by Virgilio et al. (2015) is provided
MOBILE MAPPING FOR DIGITAL DOCUMENTATION OF ANCIENT ROMAN ROADS WITHIN A MULTI-SENSOR FRAMEWORK: THE APPIAN WAY IN ROME
Immersive Appian Way health infrastructure: human centric Digital Twin (The PAAA Archeological Park of the Appian Way 12km State-Own Section, Unesco Candidature)
From Rome to Benevento, the Appian Way (Via Appia Antica) was born as a military road, 'Regina Viarum'. In 312 b.C., consul Appio Claudio extended the infrastructure for 132 miles to Capua. Many transformations and integration occurred across the centuries, resulting in a unique multi-stratified world heritage (landscape, architecture, archaeological remains and tombs along the military way). In the 19th century, Luigi Canina conceived the Appian Way as an outdoor museum, realizing a first state-own section along the 12km here surveyed and described. This year, the Ministry of Culture (MIC) has launched the UNESCO nomination for the road. The article discusses aspects of the mass digitization undertaken by the Parco Archeologico dell'Appia Antica (PAAA, the Archaeological Park of the Appian Way). The aim is to build a Digital Twin of the infrastructure supporting knowledge enhancement, preservation, design, communication and fruition. A virtual space where digital technologies and eXtended Reality are the digital arms of the contemporary Vitruvian humanistic mission and vision of the PAAA Appian Way as a source of wealth and healthiness for all the users and visitors
Experimental Infection of Brazilian Free-Tailed Bats (\u3ci\u3eTadarida brasiliensis\u3c/i\u3e) with Two Strains of SARS-CoV-2
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is presumed to have originated from wildlife and shares homology with other bat coronaviruses. Determining the susceptibility of North American bat species to SARS-CoV-2 is of utmost importance for making decisions regarding wildlife management, public health, and conservation. In this study, Brazilian free-tailed bats (Tadarida brasiliensis) were experimentally infected with two strains of SARS-CoV-2 (parental WA01 and Delta variant), evaluated for clinical disease, sampled for viral shedding and antibody production, and analyzed for pathology. None of the bats (n = 18) developed clinical disease associated with infection, shed infectious virus, or developed histopathological lesions associated with SARS-CoV-2 infection. All bats had low levels of viral RNA in oral swabs, six bats had low levels of viral RNA present in the lungs during acute infection, and one of the four bats that were maintained until 28 days post-infection developed a neutralizing antibody response. These findings suggest that Brazilian free-tailed bats are permissive to infection by SARS-CoV-2, but they are unlikely to contribute to environmental maintenance or transmission

Parotidite aguda pós-cirúgica: prevalência atual no Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo
Postsurgical acute suppurative parotitis is a bacterial gland infection that occurs from a few days up to some weeks after abdominal surgical procedures. In this study, the authors analyze the prevalence of this complication in Hospital das Clínicas/São Paulo University Medical School by prospectively reviewing the charts of patients who underwent surgeries performed by the gastroenterological and general surgery staff from 1980 to 2005. Diagnosis of parotitis or sialoadenitis was analyzed. Sialolithiasis and chronic parotitis previous to hospitalization were exclusion criteria. In a total of 100,679 surgeries, 256 patients were diagnosed with parotitis or sialoadenitis. Nevertheless, only three cases of acute postsurgical suppurative parotitis associated with the surgery were identified giving an incidence of 0.0028%. All patients presented with risk factors such as malnutrition, immunosuppression, prolonged immobilization and dehydration. In the past, acute postsurgical suppurative parotitis was a relatively common complication after major abdominal surgeries. Its incidence decreased as a consequence of the improvement of perioperative antibiotic therapy and postoperative support. In spite of the current low incidence, we believe it is important to identify risks and diagnose as quick as possible, in order to introduce prompt and appropriate therapeutic measures and avoid potentially fatal complications with the evolution of the disease.A parotidite supurativa pós-cirúrgica é infecção bacteriana da glândula que ocorre poucos dias até algumas semanas após procedimento cirúrgico. Os autores analisam a prevalência desta complicação cirúrgica nos últimos 25 anos do Hospital das Clínicas de São Paulo. Foram analisados os prontuários das cirurgias realizadas pelos serviços de Cirurgia do Aparelho Digestivo e Cirurgia Geral da Faculdade de Medicina da Universidade de São Paulo no período de 1980 a 2005, num total de 106790 cirurgias. Todos os prontuários que apresentaram entre os diagnósticos das altas complicações cirúrgicas, parotidite ou sialoadenite foram avaliados. Foram identificados 256 prontuários. Pacientes com outras complicações, ou que já apresentavam sialolitíase ou parotidite crônica anterior à internação foram excluídos do estudo. Foram identificados apenas três casos de parotidite aguda supurativa pós-cirúrgica, revelando incidência de 0,0028%. A parotidite supurativa pós-cirúrgica foi complicação relativamente comum de grandes cirurgias abdominais no passado, com acentuada redução atual da sua incidência decorrente da antibioticoterapia de amplo espectro, além de preparação pré-operatória adequada e suporte pós-operatório dos pacientes. Apesar da baixa incidência atual, consideramos importante identificar seus fatores de risco, assim como realizar diagnóstico precoce, conduta terapêutica apropriada para evitar complicações letais associadas a esta infecção
Les aspects parasitologiques de l'épidémiologie du paludisme dans le Sahara malien
Dans le cadre de l'évaluation épidémiologique de la Transsaharienne, une enquête transversale paludométrique a été réalisée d'Août 1988 à Septembre 1988 le long du tronçon malien. Neuf localités ont été visitées : Douentza, Gossi, Bourem, Almoustarat, Anefis, Aguel-Hoc, Tarlit, Tessalit, Kidal, Bouressa. 2185 unités ont été prélevées pour les études cliniques, parasitologiques et immunologiques. L'indice plasmodique global est de 5,3 % avec une grande variation du Sud (44,6 %) au Nord (0 %). L'indice gamétocytique et l'indice splénique sont très faibles. #P. falciparum est l'espèce dominante. #P. malariae a été décrit une fois en association avec #P. falciparum. #P. ovale n'a jamais été observé. Par contre un cas de #P. vivax a été décrit chez une jeune fille leucoderme de 8 ans à Kidal. #A. gambiae s.s. (forme Mopti) et #A. arabiensis sont les principaux vecteurs au Nord du Mali. Une hypothèse de circulation de #P. vivax dans le Sahara malien est émise. (Résumé d'auteur
