Recurrent and density-dependent patterns in long-term fluctuations of Atlantic bluefin tuna trap catches
Provedor de dados: 5
Autores: Royer, Francois; Fromentin, Jean-marc.
We present a methodology for the non-linear analysis of long-term ecological time series. Using a time-delay embedding procedure, we investigated the complexity of 1-dimensional signals and compared their structure to their stochastic counterparts. Recurrence-based statistics and surrogate testing were used for this purpose. The method was first tested on elementary models for illustrative purposes and its potentialities and limits reviewed. We then investigated the time structure of 6 Mediterranean bluefin tuna trap catches known to display long-term fluctuations. These time series showed significantly more determinism than linear stochastic processes, displaying more recurring patterns/states than stochastic surrogates. The short term structure of these...

Reinforcement of the pelvic diaphragm using a purse-string suture in dogs: description of technique
Provedor de dados: 45
Autores: Moraes,P.C.; Facin,A.C.; Rosa-Ballaben,N.M.; Zanetti,N.M.; Dias,L.G.G.G.
ABSTRACT Recurrence of perineal hernias is frequent, and is associated to poor identification of anatomical structures during surgery, inadequate suture placement, and failure of physical support of the pelvic diaphragm after surgical reconstruction. The objective of this work is to describe a novel surgical technique for reinforcement of the pelvic diaphragm after performing the internal obturator transposition technique in dogs with perineal hernia.

Follow-up after infants younger than 2 months of age with urinary tract infection in Southern Israel: epidemiologic, microbiologic and disease recurrence characteristics
Provedor de dados: 55
Autores: Gurevich,Evgenia; Tchernin,Dov; Schreyber,Ruth; Muller,Robert; Leibovitz,Eugene.
Abstract  Background The timing of most recurrences after neonatal urinary tract infection is during the first year of life, with peak incidence 2–6 months after the initial infection. Information on the microbiologic characteristics of recurrent urinary tract infection episodes in relation to the microbiology of the initial episodes is limited.  Objectives To analyze the epidemiologic/microbiological characteristics of 1st and recurrent urinary tract infection in infants &lt;2 months of age.  Methods A retrospective study including all infants &lt;2 months of age with urinary tract infection admitted during 2005–2009 and followed till the age of 1 year.  Results 151 neonates were enrolled (2.7% of all 5617 febrile infants &lt;2 months of age admitted)....

Presence of ductal carcinoma in situ confers an improved prognosis for patients with T1N0M0 invasive breast carcinoma
Provedor de dados: 56
Autores: Logullo,A.F.; Godoy,A.B.; Mourão-Neto,M.; Simpson,A.J.G.; Nishimoto,I.N.; Brentani,M.M.
We have retrospectively analyzed a series of 155 sequential cases of T1N0M0 ductal carcinomas of which 51 tumors had a ductal carcinoma in situ (DCIS) component for correlation between the presence of DCIS and clinicopathological variables, recurrence and patient survival. No correlations between the presence of DCIS and age, menopausal status, size, estrogen or progesterone receptors were found. High-grade infiltrative tumors tended not to present a DCIS component (P = 0.08). Patients with tumors associated with DCIS form a subgroup with few recurrences (P = 0.003) and good survival (P = 0.008). When tumors were classified by size, an association between large tumors (&gt;1.0 cm) and increased recurrence and shortened overall survival was found. The...

Abundant immunohistochemical expression of dopamine D2 receptor and p53 protein in meningiomas: follow-up, relation to gender, age, tumor grade, and recurrence
Provedor de dados: 56
Autores: Trott,G.; Pereira-Lima,J.F.S.; Leães,C.G.S.; Ferreira,N.P.; Barbosa-Coutinho,L.M.; Oliveira,M.C.
Meningiomas are common, usually benign tumors, with a high postoperative recurrence rate. However, the genesis and development of these tumors remain controversial. We aimed to investigate the presence and implications of a mutated p53 protein and dopamine D2 receptor in a representative series of meningiomas and to correlate these findings with age, gender, tumor grade, and recurrence. Tumor tissue samples of 157 patients diagnosed with meningioma (37 males and 120 females, mean age 53.6±14.3 years) who underwent surgical resection between 2003 and 2012 at our institution were immunohistochemically evaluated for the presence of p53 protein and dopamine D2 receptor and were followed-up to analyze tumor recurrence or regrowth. Tumors were classified as...
