We tested whether the fish Nile tilapia (Oreochromis niloticus) in a monosex male group spends more energy and displays an agonistic profile, differently from males in male-female groups. Such differences are expected because males and females should compete for different reproductive resources. An intruder male (MM) or female (MF) was paired with a resident male and agonistic interaction was q...

BACKGROUND Despite dedicated emergency theatre, emergency surgery can be often delayed due to competing urgencies, suggesting a need for innovative theatre time management. AIM To investigate if a change in the emergency theatre prioritisation affects outcomes for a common urgent operation such as appendicectomy. METHODS We prospectively recorded data from 67 patients undergoing appendicect...

We present a general method for extracting the Gell Mann-Low logarithmic derivative of an e ective charge of an observable directly from data as a mean for empirically verifying the universal terms of the QCD -function. Our method avoids the biases implicit in tting to QCD-motivated forms as well as the interpolation errors introduced by constructing derivatives from discrete data. We also deri...

We examined the expression of Centromere protein H (CENP-H) mRNA in 38 oral squamous cell carcinomas (SCCs), 2 epithelial dysplasias and 5 normal gingivae using the real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR). The mean expression level of CENP-H mRNA was higher in oral SCCs (0.11+/-0.08) than epithelial dysplasias (0.03+/-0.01) and normal gingivae (0.027+/-0....

A meta-analysis was performed on five studies conducted over the last decade to demonstrate a positive effect for the drug Uro-Vaxom compared with Placebo in double-blind studies in patients with urinary tract infection (601 women), with special reference to the prevention of recurrences over an observation period of 6 months, the treatment being given for the first 3 months. The five studies w...

ion/Flexibility (Wisconsin Card SortingTest; Heaton et al, 1993) The percentage of perseverative errors was used as the central parameter. Statistical analyses Frequency counts and descriptive statistics were calculated for initial basic symptoms, observed and self-perceived psychopathology. Differences in initial psychopathology between those patients at risk who experienced a transition to ps...

OBJECTIVES The aim of the study was to assess changes in the consistency of the uterine cervix and correlate the obtained results with the risk of premature delivery and time from examination to delivery MATERIAL AND METHODS Elastographic images of the cervix in a group of 44 patients, admitted to the hospital due to uterine contractions before 37 weeks of gestation, were recorded and analyze...

The purpose of this study was to select a polymer for a simulated gastric media (simHGF) to obtain rheological properties similar to that of aspirated human gastric fluid (aspHGF). Rheological characterization showed that addition of 0.2% (w/v) MC 20.000 mPa·s to simHGF provided a simulated media with rheological properties similar to that of aspHGF. INTRODUCTION Many efforts have been made tow...
