Abstract. Estuaries are among the most productive aquatic ecosystems and provide important ecological economic services in coastal areas. However, estuarine systems have been threatened worldwide by natural anthropogenic impacts acting on local, regional, global scales. Long-term studies contribute to understanding management of functioning baseline information for detection changes modeling pr...

Boehmite (γ-AlOOH) nanoparticles (NPs) are used in a wide range of industrial applications. However, little is known about their potential toxicity. This study aimed at a better understanding of the relationship between the physico-chemical properties of these NPs and their in vitro biological activity. After an extensive physico-chemical characterization, the cytotoxicity, pro-inflammatory res...

Life on Earth can be traced back to as far as 3.8 billion years (Ga) ago. The catastrophic meteoritic bombardment ended between 4.2 and 3.9 Ga ago. Therefore, if life emerged, and we know it did, it must have emerged from nothingness in less than 400 million years. The most recent scenarios of Earth accretion predict some very unstable physico-chemical conditions at the surface of Earth, which,...

The brain is treated as a nested hierarchical complex system with substantial interactions across spatial scales. Local networks are pictured as embedded within global fields of synaptic action and action potentials. Global fields may act top-down on multiple networks, acting to bind remote networks. Because of scale-dependent properties, experimental electrophysiology requires both local and g...

background: quality of life (qol) is becoming an important indicator of treatment efficacy in patients with breast cancer. most previous studies have compared patients' qol following breast conserving surgery (bcs) and mastectomy with or without reconstruction. our aim was to assess the impact of bcs versus oncoplastic breast surgery (obs). methods: selection of patients for bcs or obs was perf...

No single outcome measure can describe or predict all dimensions of recovery and disability after acute stroke. Several scales have proven reliability and validity in stroke trials, including the National Institutes of Health stroke scale (NIHSS), the modified Rankin scale (mRS), the Barthel index (BI), the Glasgow outcome scale (GOS), and the stroke impact scale (SIS). Several scales have been...

Vertical and horizontal visual analogue scales have been compared in the measurement of pain. There was a good correlation between the 2 scales, but the scores from horizontal scales tended to be slightly lower than those from vertical scales.
