BACKGROUND Total artificial heart (TAH) implantation in patients with aggressive tumor infiltration of the heart can be challenging. CASE REPORT We report on a patient with a rare primary undifferentiated high-grade spindle cell sarcoma of the mitral valve and in the left atrium, first diagnosed in 2014. The referring center did a first resection in 2014. In the course of 17 months, computer to...

Recent biological experimental findings have shown that synaptic plasticity depends on the relative timing of the pre- and postsynaptic spikes. This determines whether long-term potentiation (LTP) or long-term depression (LTD) is induced. This synaptic plasticity has been called temporally asymmetric Hebbian plasticity (TAH). Many authors have numerically demonstrated that neural networks are c...

In order to establish data be used for comparison with future evolution related climate change, physical, chemical and biological characteristics of dew rainwater as collected during the 2005 dry season (plus a few 2004 season) are reported. They have been in two characteristic tropical islands French Polynesia, Tikehau (TKH), low-lying coral atoll Tuamotu Archipelago, mountainous Tahiti island...

Composted sewage sludge (CSS) contains large amounts of organic matter and nutrients can be used as an fertilizer to improve growth, yield, quality sugarcane. However, there is a lack information regarding the impact CSS application on sugarcane seedling performance in nursery environments. A field study was conducted using randomized complete block design evaluate development, nutritional stat...

BACKGROUND Total laparoscopic hysterectomy (TLH) is safe and cost effective in early stage endometrial cancer when compared to total abdominal hysterectomy (TAH). In non-randomised data it is often hypothesised that older and obese patients benefit most from TLH. Aim of this study is to analyse whether data support this assumption to advice patients, clinicians and policy makers. METHODS Data...
