We surveyed the nematode assemblages associated with populations of the parthenogenetic whiptail lizard Ameivula nativo from six coastal restinga areas in eastern Brazil: Setiba, Comboios and Guriri (State of Espirito Santo) and Guaratiba, Prado and Maraú (State of Bahia). A total of five nematode species (Physaloptera retusa, Physalopteroides venancioi, Skrjabinelazia intermedia, Subulura lacertilia and Parapharyngodon sp.) were recorded from the six different populations of A. nativo. There was considerable variation in overall prevalence of infection (1-42%) among study sites, but geographical distance among areas did not influence similarity in the composition of nematode assemblages. Overall intensity of infection was not affected by lizard body size and did not seem to affect host body condition, based on pooled data of all populations. The studied populations of the unisexual A. nativo had relatively low prevalences and intensities of infection compared to some bisexual congeners and to sympatric lizards from other families for which such data are available. We believe that the low richness of the nematode fauna associated with A. nativo, both locally and regionally, may reflect its narrow geographic distribution and the low diversity of habitats it occupies.

A sample of 101 specimens of the unisexual whiptail lizard Cnemidophorus nativo (Squamata; Teiidae) from a coastal site in Bahia State, Brazil were examined for the presence of endoparasites. Of these, 35 (34.7%) harboured helminths. Six helminth species were recovered from C. nativo, including five nematodes (Physaloptera retusa, Physalopteroides venancioi, Subulura lacertilia, Skrjabinelazia intermedia and Parapharyngodon sp., and one cestode (Oochoristica ameivae), all representing new host records. Most lizards were infected by a single species of helminth and none by more than three. Infection rates were neither significantly influenced by host body size nor by environmental factors. The results are compared with data from studies on other whiptail species in both South and North America.

A new combinational fungicide formulation trifloxystrobin 25%+tebuconazole 50% (Nativo 75WG), introduced as a part of resistance management strategy, was studied for dissipation behaviour on apple fruits. Nativo 75WG was sprayed twice at the rate of 400 g and 800 g a.i. ha(-1) equal to trifloxystrobin application rate of 100 and 200 g a.i. ha(-1) and tebuconazole at application rate of 200 and 400 g a.i. ha(-1) at four different locations in the Northwest Himalayan region of India. The fruit samples collected at 10d interval and soil samples taken at harvest time were analyzed after second spray. The residual concentrations of trifloxystrobin, its acid metabolite CGA 321113 and tebuconazole were measured. Residues of both fungicides were determined by using gas chromatograph, Agilent 6890N having electron capture detector. The mean initial deposits of trifloxystrobin at four locations were found to be in the range of 0.333-0.387 mg kg(-1) and 0.512-0.714 mg kg(-1) at the application rate of 100 and 200 g a.i. ha(-1), and half-life were found between 19.38-24.93 d and 19.84-28.86 d at the respective doses. The Σ-trifloxystrobin and tebuconazole residues were below determination limit in 40 d apple fruits and soil samples. Initial deposits of trifloxystrobin and tebuconazole were below their Codex MRLs at the respective single doses. The half life value of the tebuconazole deposits ranged between 19.38-25.99 d and 19.84-28.86 d at the respective single and double dose. The study thus suggests 1d pre harvest interval for safe consumption of apple fruit after the application of Nativo 75 WG at single dose. Copyright © 2013 Elsevier Ltd. All rights reserved.

Resumen Introducción: Los aneurismas asociados a malformaciones arteriovenosas (MAV) son lesiones vasculares que suelen encontrarse hasta en el 15% de los casos, incrementando el riesgo global de hemorragia. La conducta frente a los aneurismas asociados es dicotómica en la literatura, mientras existen reportes de la desaparición de los mismos luego de la exéresis de la MAV, otros artículos enfatizan su tratamiento precoz. El síndrome del acento extranjero es un raro trastorno neurológico en el que el paciente habla su lengua materna como lo haría una persona extranjera y suena con “acento” extranjero a oídos de los oyentes nativos. Objetivo: Presentar un paciente que desarrolla el síndrome del acento extranjero posterior a la exéresis de una MAV y la evolución de un aneurisma asociado. Presentación de caso: Paciente pediátrico que luego de la exéresis de una MAV fronto-opercular posterior izquierda remite por completo un aneurisma de hiperflujo asociado, presentando en el postquirúrgico el síndrome del acento extranjero. Conclusión: Queda reportado el caso de este raro síndrome y la resolución espontánea de un aneurisma proximal luego de la exéresis de una MAV. PMID:28480115

To translate and perform the cultural adaptation of the tool Functional Assessment of Chronic Illness Therapy - Cervical Dysplasia (FACIT-CD) to the Portuguese language. A descriptive cross-sectional study, with translation and cultural adaptation of the assessment tool performed according to international guidelines and the Functional Assessment of Chronic Illness Therapy (FACIT) protocol group. It involved eight experts, six from Brazil, one from Portugal and one from the United States. After translation and back-translation of the tool, the semantic analysis process was carried out. We randomly included 20 women aged between 18 and 70 years with altered cervical cytology exam, seen at the Department of Prevention and Gynecologic Oncology - Hospital de Câncer de Barretos. The sample consisted of women with low education level. In the first pre-test, ten women participated and half of them considered the questions CD1, CD2 and CD3 as difficult, because they did not understand the meaning of the term "pelvic area". The question CD5, "I worry about spreading the infection", was also considered difficult to understand by five women. After the reconsideration of the expert committee and FACIT group, the second pre-test was performed. At this stage, we concluded that the previously raised understanding problems had been solved. The translated version of FACIT-CD in universal Portuguese language is equivalent to the original version in English and was easily understood by patients with cervical intraepithelial neoplasia.

Peer review is now a commonplace practice in process-oriented writing instruction. A crucial aspect of peer review is assessing another classmate's work, which encompasses the act of disagreement. Given its prevalence in the classroom, it is necessary to analyze how L2 learners mitigate disagreement in the context of peer review with other L2…
