OBJECTIVE To evaluate the effect of preoperative supplementation of omega-3 fatty acids on the healing of colonic anastomoses in malnourished rats receiving paclitaxel. METHODS we studied 160 male Wistar rats, divided in two groups: one subjected to malnutrition by pair feeding (M) for four weeks, and another that received food ad libitum (W). In the fourth week, the groups were further divid...

Sir, Since the initial reports of vancomycin-resistant enterococci (VRE) in the late 1980s, increasing numbers of such isolates have been identified in centres in both Europe and the U S A . , 2 In 1998, Fujita et al. were the first authors in Japan to describe the isolation of a vancomycin-resistant strain of Enterococcus faecium from a patient with a urinary tract infection. To date, 10 strai...

The timing of action potentials in sensory neurons contains substantial information about the eliciting stimuli. Although the computational advantages of spike timing–based neuronal codes have long been recognized, it is unclear whether, and if so how, neurons can learn to read out such representations. We propose a new, biologically plausible supervised synaptic learning rule that enables neur...

Music and speech are very cognitively demanding auditory phenomena generally attributed to cortical rather than subcortical circuitry. We examined brainstem encoding of linguistic pitch and found that musicians show more robust and faithful encoding compared with nonmusicians. These results not only implicate a common subcortical manifestation for two presumed cortical functions, but also a pos...

Embryogenesis is the beginning of plant development, yet the cell fate decisions and patterning steps that occur during this time are reiterated during development to build the post-embryonic architecture. In Arabidopsis, embryogenesis follows a simple and predictable pattern, making it an ideal model with which to understand how cellular and tissue developmental processes are controlled. Here,...

The operating point of a propeller hydropower station will deviate from the effective workspace while discharge reduces excessively during dry seasons. It usually leads to decrease in efficiency and even being unable work. To solve above problem, scheme named decreasing capacity increase was presented this article. A low-specific-speed runner with fixed blades that has same installing dimension...

The management of impacted third molars (M3s) or wisdom teeth is a decision encountered by oral and maxillofacial surgeons (OMSs) daily. The decision-making is usually very straightforward, owing to the presence of disease. A challenging management decision is how to manage the asymptomatic, disease-free wisdom tooth. For these types of M3s, the treatment is essentially a binary choice: (1) ope...
