Anuran Species Of The Salto Morato Nature Reserve In Paraná, Southern Brazil: Review Of The Species List

We provide an updated checklist of the anurans of the Salto Morato Nature Reserve (SMNR), Paraná, southern Brazil, including information on species endemism, conservation status, habitat use, and reproductive modes. We sampled the study area between February 2013 and July 2015, using Visual Encounter Surveys, totaling 700 hours of sampling effort. We supplement our primary data with secondary data (published papers and voucher specimens), and through these, we found a total of 54 anuran species representing 23 genera and 10 families. All the frogs recorded are endemic to the Atlantic Forest. Although no species has been listed as Endangered on the Red Lists of Paraná state, Brazil, and the IUCN, five are classified as Data Deficient. Most of the species recorded were arboreal (55.5%), a third were terrestrial (33.3%), and the remainders were rheophilic (11.1%). We identified 18 different reproductive modes, with types 1 (lay eggs in lentic water where the tadpoles develop) and 23 (direct development of terrestrial eggs) being the most common. Our findings indicate that the SMNR currently has the greatest diversity of anuran species and reproductive modes of any area in southern Brazil. © 2016 Check List and Authors.12

ÍNDICES PROLIFERATIVOS DO TUMOR VENÉREO CANINO TRANSMISSÍVEL PELAS TÉCNICAS DO CEC E KI-67 NA CITOLOGIA ASPIRATIVA COM AGULHA FINA

A citologia aspirativa com agulha fina (CAAF) foi usada como método de colheita de quinze amostras de tumor venéreo transmissível (TVT)em cães, oriundos do atendimento do Hospital Veterinário-FMVZ-UNESP de Botucatu, antes e após o início da quimioterapia. As amostras citológicas foram submetidas ao cálculo do índice mitótico e à avaliação de índices de proliferação por métodos citoquímico (concentração eletrolítica crítica CEC) e imunocitoquímico (Ki-67, clone MIB-1). Todas as técnicas mostraram-se adequadas para avaliar a taxa proliferativa em amostras citológicas. O CEC permitiu observar que a aplicação do quimioterápico levou a uma redução significativa da proliferação celular. Em vista disso, conclui-se que essa metodologia pode ser aplicada para diagnosticar e monitorar o TVT. Proliferation indexes determination by CEC and Ki-67 in fine needle aspiration cytology of transmissible venereal tumor Abstract Fine needle aspiration biopsy (FNAB) was used to collect fifteen transmissible venereal tumor (TVT) samples from dogs at the Veterinary Hospital - FMVZ - UNESP Botucatu, São Paulo, Brazil, before and after beginning of chemotherapy. The cytological samples were submitted to determination of mitotic and proliferation indexes by means of cytochemical (critical electrolyte concentration CEC) and immunocytochemical (Ki-67, MIB-1 clone) methods. All the techniques were adequate for the evaluation of proliferation rates displayed by the cytological samples. The CEC allowed the observation that chemotherapy induces to significant reduction in cellular proliferation. Thus, was concluded that this methodology is suitable to perform TVT diagnosis and monitoration

Purification and characterization of a variant of human prothrombin: prothrombin Segovia

A dysprothrombin designated prothrombin Segovia was isolated from the plasma of an individual with normal prothrombin antigen and prothrombin activity lesser than 25% of the control prothrombin activity. Activation by prothrombinase complex showed a lower amidolytic than clotting activity, which suggests a lesser generation of active intermediates than normal prothrombin. When prothrombin Segovia was activated by prothrombinase complex in the absence of factor Va, no thrombin formation was found by functional activities. SDS-PAGE analysis of the molecules derived by activation with prothrombinase complex, Taipan snake venom and Echis carinatus venom showed an accumulation of molecules not cleaved at bond Arg320-Ile321. This was more evident with Echis carinatus venom, which only acts on this bond. Our data suggest that the alteration of prothrombin Segovia impairs the scission of bond Arg320-Ile321

Supporting pruning in tabled LP

This paper analyzes issues which appear when supporting pruning operators in tabled LP. A version of the once/1 control predicate tailored for tabled predicates is presented, and an implementation analyzed and evaluated. Using once/1 with answer-on-demand strategies makes it possible to avoid computing unneeded solutions for problems which can benefit from tabled LP but in which only a single solution is needed, such as model checking and planning. The proposed version of once/1 is also directly applicable to the efficient implementation of other optimizations, such as early completion, cut-fail loops (to, e.g., prune at the top level), if-then-else, and constraint-based branch-and-bound optimization. Although once/1 still presents open issues such as dependencies of tabled solutions on program history, our experimental evaluation confirms that it provides an arbitrarily large efficiency improvement in several application areas

Superinflation, quintessence, and nonsingular cosmologies

The dynamics of a universe dominated by a self-interacting nonminimally coupled scalar field are considered. The structure of the phase space and complete phase portraits are given. New dynamical behaviors include superinflation ($\dot{H}>0$), avoidance of big bang singularities through classical birth of the universe, and spontaneous entry into and exit from inflation. This model is promising for describing quintessence as a nonminimally coupled scalar field.Comment: 4 pages, 2 figure

N-terminal-pro-B type natriuretic peptide as a useful tool to evaluate pulmonary hypertension and cardiac function in CDH infants

Objective: In congenital diaphragmatic hernia (CDH) the severity of pulmonary hypertension (PH) is considered, by several authors, determinant of clinical outcome. Plasmatic N-terminal-pro-B type natriuretic peptide (NT-proBNP) might be useful in diagnosis and management of PH in newborns, although its interest in CDH infants remains to be defined. Early NT-proBNP levels were assessed in CDH infants and correlated with cardiovascular echocardiographic parameters. Patients and Methods: 28 newborns, CDH and age-matched controls were enrolled in a prospective study. Clinical condition, NT-proBNP plasmatic levels, echo parameters of PH and biventricular function were assessed at 24 h after delivery as well as survival outcome. Results: Estimated mean pulmonary pressure and NT-proBNP were significantly higher in CDH than control infants. NT-proBNP significantly correlated with estimated pulmonary artery pressure, right ventricular Tei index, and tricuspid E/A ratio. Additionally, we found that CDH infants with NT-proBNP >11,500 pg/ml experienced a worse prognosis. Conclusions: We demonstrated that PH is associated with NT-proBNP elevation and diastolic impairment in CDH infants. Early elevations in NT-proBNP levels seem to alert for a subset of CDH infants with worse prognosis. Copyrigh

Identifying and managing patient–ventilator asynchrony: An international survey.

Objective: To describe the main factors associated with proper recognition and management of patient ventilator asynchronies (PVA). Design: Analytical cross-sectional study. Setting: International study conducted in 20 countries through an online survey. Participants: Physicians, respiratory therapists, nurses and physiotherapists that are currently working at the Intensive Care Unit (ICU). Main variables of interest: Univariate and multivariate logistic regression models were used to establish associations between all variables (profession, training in mechanical ventilation, type of training program, years of experience and ICU characteristics) with the ability of HCPs to correctly identify and manage 6 PVA. Results: A total of 431 HCPs answered a validated survey. The main factors associated with the proper recognition of PVA were: specific training program in mechanical ventilation (MV) (OR 2.27; 95% CI 1.14-4.52; p = 0.019), courses with more than 100 hours completed (OR 2.28; 95% CI 1.29-4.03; p = 0.005) and the number of intensive care unit (ICU) beds (OR 1.037; 95% CI 1.01-1.06; p = 0.005). The main factor that influenced PVA management was recognizing 6 PVA correctly (OR 118.98; 95%CI 35.25-401.58; p < 0.001). Conclusion: Identifying and managing PVA using ventilator waveform analysis is influenced by many factors including specific training programs in MV, number of ICU beds and the recognized number of PVA.pre-print169 K
