Noite escura de São Nunca: processo de criação e realização de curta-metragem
Este relatório compreende a descrição de todo o processo de realização do filme Noite Escura de São Nunca, desde sua concepção até a fase final de montagem. O filme é um curta-metragem de caráter experimental que aborda a presença traumática da violência perpetrada por forças militares no cotidiano de duas mulheres. Um delas teve a irmã desaparecida durante a ditadura civil-militar que se impôs no Brasil de 1964 a 1985, e a outra foi presa pela polícia militar durante as manifestações que se iniciaram a partir de junho de 2013. O filme busca estabelecer uma relação entre esses dois episódios a partir do cotidiano de uma aparentemente pacata vila localizada no Centro do Rio de Janeiro

The Isolation and Identification of Stress Tolerance Ethanol-fermenting Yeasts from Mozzarella Cheese Whey
Bioethanol conversions has long been considered as a possible solution for whey utilization. The existence of wild ethanol-fermenting yeasts that able to hydrolyze lactose become an important thing. Aims of the research was to isolate and identified the potential ethanol-fermenting yeasts from mozzarella cheese whey. Research done experimentally and analyzed descriptively. Yeast candidates isolated from mozarella cheese whey with pour plate method and purified on Potato Dextrose Agar (PDA) with the addition of 3% Yeast Extract and 10 ppm of Amoxycillin. The candidates were tested to stress tolerance towards various sugar and ethanol contents. Ethanol-fermenting yeast candidates tested in converting whey into bioethanol by inoculating 2% isolates into mozzarella cheese whey and incubated in room temperature (26-28°C) for 48 hours, then the ethanol contents tested by Gas Chromatography. The isolate that gave the highest ethanol contents identified using RapID Yeast Plus System. Results showed that there are 5.8 x 105 cfu/ml yeasts population in mozzarella cheese whey with four isolates that has different macroscopic character. Four candidate showed endurance towards 30% sugar and 20% ethanol contents and isolate W2 chosen as best isolate that produce the highest ethanol contents of 1,515.973 ppm. RapID Yeast Plus System has identified the isolate W2 has 96.43% similarity with Candida lambica
Effect of Macronutrient Needs on Digestibility and Average Daily Gain of Sheep (Ovisaries var. Padjadjaran, Family Bovidae)
Feeding management is a very important factor that makes sure fulfil quality and quantity for livestock nutrient sufficiency that affects the success rate in livestock farming. The excellent macro nutrient needs determination is an absolute thing to achieve the optimal growth which represented by digestibility and average daily gain. Feed formulation that considering the material selection, availability, and the price of feed materials could gave sustainable livestock feed management. The study was carried out to evaluate the effect of macronutrients needs on digestibility and average daily gain of sheep. Twenty Padjadjaran sheep (Ovisaries var. Padjadjaran, Family Bovidae), which resulted from crossbreeding between South-African Capstaad, Merino, and local, were chosen as tested animals. These white sheep were placed separately in individual metabolism cages. All animals were 8-10 months of age and their body weights ranged between 15-33 kg. The animals were divided into 5 groups and each group was treated with different dietary feeds (4 times replication) that contained dry material, crude protein, crude fiber, crude fat, and nitrogen-free extract (NFE). The parameters measured were dry matter intake (DMI), dry matter digestibility (DMD), organic matter digestibility (OMD) and average daily gain (ADG). The treatments showed no significant effect on DMI, DMD, and OMD, whereas an increase of ADG (113.33 – 169.17 g/animal/day) was observed on all animals. One of R2-treated animal showed an increase of 276.67 g/day
Thermochemical effects on hypersonic shock waves interacting with weak turbulence
The interaction between a weakly turbulent free stream and a hypersonic shock wave is investigated theoretically by using linear interaction analysis (LIA). The formulation is developed in the limit in which the thickness of the thermochemical nonequilibrium region downstream of the shock, where relaxation toward vibrational and chemical equilibrium occurs, is assumed to be much smaller than the characteristic size of the shock wrinkles caused by turbulence. Modified Rankine-Hugoniot jump conditions that account for dissociation and vibrational excitation are derived and employed in a Fourier analysis of a shock interacting with three-dimensional isotropic vortical disturbances. This provides the modal structure of the post-shock gas arising from the interaction, along with integral formulas for the amplification of enstrophy, concentration variance, turbulent kinetic energy (TKE), and turbulence intensity across the shock. In addition to confirming known endothermic effects of dissociation and vibrational excitation in decreasing the mean post-shock temperature and velocity, these LIA results indicate that the enstrophy, anisotropy, intensity, and TKE of the fluctuations are much more amplified through the shock than in the thermochemically frozen case. In addition, the turbulent Reynolds number is amplified across the shock at hypersonic Mach numbers in the presence of dissociation and vibrational excitation, as opposed to the attenuation observed in the thermochemically frozen case. These results suggest that turbulence may persist and get augmented across hypersonic shock waves despite the high post-shock temperatures.C.H. was funded by a 2019 Leonardo Grant for Researchers and Cultural Creators awarded by the BBVA Foundation, and by the MICINN Grant No. PID2019–108592RB-C41
MDMA Intoxication in potential donor with cardiac arrest – A case report
Poster apresentado no 57th Annual Meeting of The International Association of Forensic Toxicologists, Birmingham (Reino Unido), 2019Amphetamines consumption is still an important public health issue, namely in terms of compounds variability and disposition to consumers. However, some of them, still classic substances, keep standing in the illicit market, with remarkable and continuous success. That is the case of MDMA. Nevertheless, there is always new information and data on MDMA intoxication, both in vivo as in post-mortem context.
The authors report an intoxication case with MDMA in an 18 years old male, who was considered a potential organ donor, after a cardiac arrest. Whole blood samples were collected in vivo, at the Emergency Room (ER), in different moments, and post-mortem, at the Forensic Pathology Service of the National Institute of Legal Medicine and Forensic Science.
After a general screening procedure, samples were extracted by an SPE procedure (OASIS® MCX) followed by a GC-MS single quad analysis. The post-mortem whole blood sample was positive for Lidocaine (< 500 ng/mL), compatible with ER intervention, and positive for MDMA (2278 ng/mL) and MDA (49 ng/mL), while the whole blood samples collected in vivo (during the maintenance of the individual under advanced life support), were positive for MDMA (between 504 ng/mL and 1918 ng/mL) and MDA (between 20 ng/mL and 89 ng/mL). The samples were negative for other substances, namely ethanol, other drugs of abuse and medicines.
Interpretation of these results is pivotal to understand the behaviour of the substance. So, in this case, MDMA post-mortem behaviour should be carefully evaluated, considering as possible influencers, in the specific context of the case, the time lapse between the death verification, the maintenance of the advanced life support and the body manipulation for organ collection purposes. Also referred and discussed is the ante-mortem/post-mortem ratio of MDMA obtained values, compared with literature references. No doubt that death was due to MDMA intoxication, but information from the in vivo samples analysis suggests that this type of sample should also be considered, in a complementary role, whenever possible.N/
Biotic, abiotic, and anthropogenic drivers of demographic performance of non-native Eucalyptus and Pinus species in forested areas of Spain
Non-native trees enhance services that are fundamental for human well-being. Yet, the extensive use of non-native trees has the potential of causing environmental and socio-economic harm. Eucalyptus and Pinus are the most widely distributed and extensively planted tree genera worldwide, because their rapid growth allows profitable production of timber and pulp. Their naturalization is causing severe effects on the environment, but the relative importance of underlying factors determining their demographic performance is not well known. Thus, our aim was to evaluate the relative importance of biotic, abiotic, and anthropogenic factors driving demographic changes of Eucalyptus and Pinus at the regional scale. We compiled environmental variables and demographic data for Eucalyptus globulus, Eucalyptus camaldulensis, and Pinus radiata across 6388 permanent forestland plots surveyed in the Spanish Forest Inventory (SFI). We used the second (1986?1996), third (1997?2007), and fourth (2008?2017) SFI datasets to quantify annual changes in basal area per plot between consecutive inventories (?BA; m2 ha?1 year?1). We also quantified the components of ?BA: tree ingrowth (transitions from juvenile to adult trees), growth, and mortality. We evaluated juvenile recruitment with in-situ regeneration (No. juvenile trees ha?1) within plots already occupied by the focal species in the previous inventory, and with natural colonization of plots where the focal species was absent at the beginning of the time interval. We found that the structure of the biotic community was especially important to explain demographic performance of non-native trees growing in benign environments (E. globulus and P. radiata), whereas abiotic factors were particularly important regulating basal area increments of E. camaldulensis, which occurs in harsher environments. Basal area increments decreased with species and functional richness, heterospecific density, mean annual temperature, and increased with soil capacity to retain nutrients and water. Colonization of new plots increased with propagule availability in the surrounding landscape. Tree cutting was beneficial for P. radiata. Collectively, our results suggest that non-native trees perform better in forests with high propagule pressure, low biotic resistance, favourable abiotic conditions, and human management.Agencia Estatal de InvestigaciónUniversidad de AlcaláMinisterio de Ciencia e InnovaciónComunidad de Madri
Asociación entre eosinófilos de sangre periférica y cutáneos con la gravedad del penfigoide ampolloso y los resultados terapéuticos
© 2022 AEDV. Published by Elsevier España, S.L.U. This is an open access article under the CC BY-NC-ND license (http:// creativecommons.org/licenses/by-nc-nd/4.0/).Background and aims: A dermal inflammatory infiltrate rich in eosinophils is a prominent histological feature of bullous pemphigoid (BP) and peripheral blood eosinophilia has been documented in 50-60% of BP patients. Nevertheless, the impact of circulating and dermal infiltrate eosinophil levels on BP remains poorly understood. The main objective of this work was to investigate the association of peripheral blood and dermal infiltrate eosinophil levels with clinical and immunological characteristics of the disease.
Material and methods: Retrospective cohort study including all patients diagnosed with BP between 2011 and 2020.
Results: The study cohort included 233 patients with BP. The mean baseline peripheral blood eosinophil count was 956.3 ± 408.6 × 106/L and the mean number of tissue eosinophils at the dermal hot spot area was 30.5 ± 19.0. Patients with disseminated presentation (i.e. BSA > 50%) had significantly higher peripheral blood eosinophil counts (P = .028). Mucosal involvement was significantly associated with lower dermal eosinophil count (P = .001). Requiring inpatient care and relapsing were significantly associated with high peripheral blood eosinophil count (P = .025; P = .020, respectively). Among the 68 patients who experienced a relapse, 31 had peripheral blood eosinophilia (i.e. > 500 × 106/L) at relapse (44.2%). Peripheral blood eosinophil counts at baseline and at relapse were significantly correlated (r = 0.82, P < .001).
Conclusions: Peripheral blood and cutaneous eosinophils levels may be useful biomarkers for disease activity and treatment outcomes in BP. Monitoring peripheral blood eosinophil counts may allow early detection of relapse.info:eu-repo/semantics/publishedVersio
Clinic-epidemiological analysis of an Otorhinolaryngology Emergency Unit Care in a Tertiary Hospital
AbstractEmergencies are common in our Otorhinolaringology specialty. However, the clinical and epidemiological features are not very well known.ObjectivesTo evaluate the clinical and epidemiological profiles of otorhinolaryngological disorders in an emergency unit of a tertiary hospital, and to determine the appropriateness of the level of health care for a tertiary hospital.Materials and methodsAn analytical study using data records of an otorhinolaryngological emergency unit at a tertiary hospital in the Federal District for a year, full time, and no screening. The age, sex, arrival time and clinical diagnosis were evaluated. The entities were separated into cases of pharingolaryngoesthomatology, otology, rhinology, and head and neck surgery. These were evaluated according to the urgency level, the required care, and the arrival time.Results26,584 data records were selected, of which 2,001 were excluded. The group comprised 54.48% women, and 45.51% men. Otological complaints (62.27%) prevailed. 61.26% of cases were considered emergencies. Only 9.7% of those required medium or high complex resources for resolution.ConclusionThe study showed that 61.26% of the otorhinolaryngological cases are emergencies, and only 9.7% required medium or high complexity resources
