Characters’ identities are integral to how audiences relate to them. But what happens when the character suddenly alters his or her outward appearance? Are they still the same person? This thesis seeks to argue that disguise does not alter a character’s true nature, as evidenced by Pyrocles in Sir Philip Sidney’s The Countess of Pembroke’s Arcadia and the Prince in Margaret Cavendish’s The Convent of Pleasure. Both Pyrocles’ suit of Philoclea and the Prince’s suit of Lady Happy are successful because, however subversive they appear at first, they ultimately adhere to societal norms of the time. The relationship between the cross-dressed prince and his love interest in both works only appears to subvert heteronormative expectations for the time, but ultimately adheres to these societal norms once the disguised character’s true identity is revealed to his chosen partner.

Introdução: a avaliação da pressão inspiratória nasal (SNIP) é considerada uma manobra complementar da Pressão Inspiratória Máxima estática (PImax) em várias condições clínicas, porém não há relatos na obesidade. Por outro lado, a obesidade tem um importante impacto nos músculos respiratórios especialmente com maiores gordura abdominal o que provavelmente pode ser detectado na avaliação da SNIP que mensura mais precisamente a pressão diafragmática. Objetivo: analisar em obesos a relação entre SNIP e variáveis respiratórias e marcadores de adiposidade. Material e Método: num estudo transversal um total de 92 obesos (38.3±10.2 anos) sem história de doença respiratória ou cardíaca diagnosticada. Foram avaliados na espirometria (capacidade vital forçada-CVF; volume expiratório forçado no primeiro segundo-VEF1; volume de reserva expiratório-VRE) e pressões respiratórias estática (PImax, PEmax e SNIP) e dinâmica (ventilação voluntária máxima-VVM). Sendo considerados os marcadores de adiposidade: índice de adiposidade corporal-IAC; índice de massa corporal-IMC e circunferências do quadril (CQ), cintura (CC) e pescoço (CP). Resultados: 65 obesos mórbidos (IMC=50.8±8.1Kg/m2) e 27 obesos não mórbidos (IMC=35.6±2.7Kg/m2) foram homogêneos (p>0.05) na SNIP (99.1±24.5cmH2O, 87% do predito) e PImax (107.3±26.4cmH2O, 109% do predito). Existe correlação (r=0.5) entre SNIP e PImax somente no grupo de obesos mórbidos. De acordo com as correlações houve associação entre variáveis respiratórias (CVF r=0.48; VEF1 r=0.54; e VVM r=0.54), valores antropométricos (idade r=-0.44) e SNIP somente para os obesos mórbidos. Esses achados foram certificados quando também comparados a quantidade de gordura ao redor do pescoço (CP≥43cm). O modelo de regressão linear stepwise mostrou que a VVM parece ser o melhor preditor para explicar a SNIP nos obesos mórbidos. Nestes obesos a SNIP foi levemente mais baixa (87%predito) que os valores esperados para indivíduos brasileiros saudáveis. Conclusão: em obesos mórbidos a SNIP é moderadamente relacionada a PImax. A SNIP parece ser mais relacionada a VVM que à marcadores de adiposidade.

There are two features of /æ/ in British Columbia (BC) English that are widely attested in the literature: it is undergoing retraction and lowering and it is sensitive to the influence of certain following consonants. The present study aims to utilize both features to evaluate the phonological status of /æ/ before nasal consonants in BC English by examining the progression of sound change and the phonemic organization of /æ/ in different environments. Specifically, production and perception results are taken together to evaluate the phonetic position of pre-nasal /æ/ relative to other environments. These results are interpreted within a modular feedforward architecture of phonology to establish the phonological (allophonic) and phonetic (shallowphonic) rules that govern the internal relationships between the subphonemic elements of /æ/ in BC English. Further, the findings of this study provide evidence for the allophone being the target of sound change, rather than the phoneme.

Different types of network oscillations occur in different behavioral, cognitive, or vigilance states. The rodent hippocampus expresses prominentoscillations atfrequencies between 4 and 12Hz,which are superimposed by phase-coupledoscillations (30 –100Hz).These patterns entrain multineuronal activity over large distances and have been implicated in sensory information processing and memory formation. Here we report a new type of oscillation at near- frequencies (2– 4 Hz) in the hippocampus of urethane-anesthetized mice. The rhythm is highly coherent with nasal respiration and with rhythmic field potentials in the olfactory bulb: hence, we called it hippocampal respiration-induced oscillations. Despite the similarity in frequency range, several features distinguish this pattern from locally generatedoscillations: hippocampal respiration-induced oscillations have a unique laminar amplitude profile, are resistant to atropine, couple differentlytooscillations, and are abolished when nasal airflow is bypassed bytracheotomy. Hippocampal neurons are entrained by both the respiration-induced rhythm and concurrent oscillations, suggesting a direct interaction between endogenous activity in the hippocampus and nasal respiratory inputs. Our results demonstrate that nasal respiration strongly modulates hippocampal network activity in mice, providing a long-range synchronizing signal between olfactory and hippocampal networks.

The permanent contact with cork may lead to constant exposure to fungi, raising awareness as a potential occupational hazard in the cork industry.The presence of fungi belonging to the Penicillium glabrum complex has been associated with the development of respiratory diseases such as suberosis, one of the most prevalent diseases among workers from cork industries, besides occupational asthma. Azoles are used as pesticides but also the first line therapy in the treatment of Aspergillus infections; azole-resistance as been described as to have also an environmental source and is considered an emerging public health problem.The aim of this work was to characterize fungal distribution and to evaluate the presence of azole-resistant Aspergillus isolates in nose swab samples from the cork industry workers.

Introduction: Formaldehyde is a compound with a wide range and is commonly used in anatomy and pathology laboratories. At room temperature is quickly volatilized to a pungent and suffocating gas and its inhalation has been correlated to nuclear alterations in different tissues. We aimed to investigate whether exposure to this compound was correlated with the appearance of cytotoxic and genotoxic features in the nasal epithelial cells of students enrolled in a human anatomy course. Material and Methods: This prospective study collected periodically nasal cells from mucosa of 17 volunteers from two different undergraduate programs with different workloads of practical lessons in an anatomy laboratory, 30 and 90 hours per semester. Cells were staining according to Feulgen method and nuclear morphology was analyzed to detect possible damage. Dunn's post hoc test was used in the statistical analysis. Pearson's correlation was performed for gender, age and questionnaire responses. Results: Epithelial cells showed indicators of cytotoxicity and mutagenicity. Students with a more extensive workload in anatomy laboratory displayed a more severe profile with an increase in karyorrhexis (p < 0.05) over time. The micronucleus analysis showed difference between first and second collection (p < 0.01), although it was not maintained over the time. Students with a less extensive workload display no differences in most of cytological features. Despite karyorrhexis was present in a greater number of cells, for this group no significant difference was observed between any range. The same was observed to karyolysis and micronucleus (p > 0.05). Conclusion: Individuals exposed for short periods of time to formaldehyde are subject to the toxic action of this gas. Karyorrhexis was the most frequently observed cytotoxic feature and micronucleus showed an increase between the first time point. The patterns observed between the student's groups suggest a negative effect due to exposure time.

Durante su ciclo de vida las tortugas marinas están expuestas a muchos peligros, cada año mueren al ser capturadas accidentalmente en las redes de pesca, víctimas de la pérdida de hábitat de áreas de alimentación y anidación, debido al desarrollo costero e incremento del turismo, lo anterior ha ocasionado que se les considere como especies en peligro o amenazadas de extinción. La mayoría de las enfermedades de las tortugas marinas aún no han sido descritas; por lo que es necesario conocer las bacterias que se encuentran presente en el organismo y los posibles vectores de enfermedades. El objetivo del presente estudio fue determinar la composición de la flora bacteriana en el área nasal y cloacal de las tortugas marinas Lepidochelys olivacea durante su época de anidación entre los meses de junio a octubre del año 2012, se colectaron muestras bacteriológicas provenientes de 20 hembras anidantes mediante recorridos nocturnos en tres playas El Faro, El Cocal y Salinitas pertenecientes al Área Natural Protegida Complejos Los Cóbanos Departamento de Sonsonate, El Salvador. Las muestras se colectaron a través del uso de hisopos estériles que se introdujeron en la cloaca durante el desove y en uno de los conductos nasales. Estas fueron trasladadas en al laboratorio de Biología de la Universidad de El Salvador en menos de 24 horas para su posterior análisis. En el laboratorio las muestras nasales fueron cultivadas en agar sangre, MacConkey y agar manitol sal, las cloacales fueron cultivadas en agar sangre, MacConkey, TCBS y XLD, a todas las colonias aisladas se les realizaron pruebas bioquímicas rutinarias IMVIC. Además se utilizó API 20E.

Resumen La conidiobolomicosis es una enfermedad causada por Conidiobolus spp. que afecta a varias especies de animales, incluyendo ovinos, llamas, ciervos, caballos, perros y humanos. En ovinos se caracteriza por lesiones granulomatosas en la cavidad nasal. Aunque la enfermedad es endémica en distintas regiones de Brasil, aún no ha sido reportada en Uruguay. El objetivo de este trabajo es describir un caso de conidiobolomicosis nasal en una oveja en Uruguay y proveer una breve revisión bibliográfica. El caso ocurrió en marzo del 2015 en una oveja de 19 meses de edad en un establecimiento ubicado en el departamento de Colonia. Los principales signos clínicos fueron debilidad, secreción nasal, obnubilación, torneo y exoftalmos unilateral. Los principales hallazgos patológicos fueron rinosinusitis granulomatosa necrotizante localmente extensiva, afectando la región posterior de la cavidad nasal, con desplazamiento del tabique nasal y osteítis necrotizante/osteolítica de los huesos faciales, con extensión al tejido subcutáneo facial y espacio retro-ocular derechos. Microscópicamente se constató la presencia de hifas intralesionales, identificadas por inmunohistoquímica como Conidiobolus spp., rodeadas por material de Splendore-Hoeppli. Se concluye que la conidiobolomicosis ocurre esporádicamente en Uruguay y que debe ser considerada dentro de los diagnósticos diferenciales de rinitis en ovinos en este País

Background: Respiratory distress syndrome (RDS) is one of the most common diseases in neonates admitted to NICU. For this important cause of morbidity and mortality in preterm neonates, several treatment methods have been used. To date, non-invasive methods are preferred due to fewer complications. Objectives: Herein, two non-invasive methods of ventilation support are compared: NCPAP vs. NIPPV. Patients and Methods: This is a randomized clinical trial. Premature neonates with less than 34 weeks gestation, suffering from RDS entered the study, including 151 newborns admitted to Vali-Asr NICU during 2012-2013. Most of these patients received surfactant as early rescue via INSURE method and then randomly divided into two NCPAP (73 neonates) and NIPPV (78 neonates) groups. Both early and late complications are compared including extubation failure, hospital length of stay, GI perforation, apnea, intraventricular hemorrhage (IVH) and mortality rate. Results: The need for re-intubation was 6% in NIPPV vs. 17.6% in NCPAP group, which was statistically significant (P = 0.031). The length of hospital stay was 23.92 ± 13.5 vs. 32.61 ± 21.07 days in NIPPV and NCPAP groups, respectively (P = 0.002). Chronic lung disease (CLD) was reported to be 4% in NCPAP and 0% in NIPPV groups (P = 0.035). The most common complication occurred in both groups was traumatization of nasal skin and mucosa, all of which fully recovered. Gastrointestinal perforation was not reported in either group. Conclusions: This study reveals the hospital length of stay, re-intubation and BPD rates are significantly declined in neonates receiving NIPPV as the treatment for RDS.
