We include examples of other neighbourhoods and asynchronous updating that confirm the robustness of our conclusions. Our results pave the way to an evolutionary rationale for modelling social VS-4718 order interactions through

game theory with a preferred set of update rules. (C) 2009 Elsevier Ltd. All rights reserved.”
“We hypothesized that magnetic resonance imaging (MRI) can assess fetuses with sonographically (ultrasonography (US))-suspected neural tube defects (NTD) that might influence their diagnoses and management decision.

Institutional review board approval and informed consents were obtained to perform MRI for 19 fetuses referred with US-suspected NTD. Prenatal imaging findings were correlated RepSox mw with management decision, postnatal clinical, postnatal imaging, and pathology.

Prenatal MRI correctly ruled out US diagnosis of cephalocele in a fetus. In the other 18 fetuses, MRI detected detailed topography and contents of NTD sacs in five, added central nervous system (CNS) abnormalities that were not apparent on US in three, and confirmed non-CNS findings in three fetuses. MRI changed diagnosis of 3/19 fetuses (15.8%), caused minor change in diagnosis

of 5/19 (26.3%), and did not influence US diagnosis of 11/19 fetuses (57.9%). MRI findings changed/modified management decision in 21% of the fetuses.

Fetal MRI is an important adjunct to US in assessing NTD. It can identify topography and contents of sacs, add CNS and non-CNS findings, and influence management decision.”
“Motivated by recent experiments on intracellular calcium release we study the effects of different types of coupling on the dynamics of arrays of excitable elements. We intend to find a mechanism that produces a sustained activity

of the elements following a spike. While instantaneous diffusive coupling does not exhibit this property, we show that, for a coupling term with temporal delay, signals from adjacent elements can serve as mutual excitations and thus prolong the duration of the signal. We propose that time delayed coupling is generated by diffusion 17-DMAG (Alvespimycin) HCl between isolated clusters of calcium channels. Our model could thus provide an explanation for two different release modes observed in the Ca2+ system. (C) 2009 Elsevier Ltd. All rights reserved.”
“The aim of this work is to assess the usefulness of apparent diffusion coefficient (ADC) value of the brain for diagnosis of patients with Gaucher’s disease type II and type III.

Prospective study was conducted upon 13 patients (nine boys and four girls aged 8 months-14 years: mean 6.1 years) with Gaucher’s disease type II and III and for age-matched control group (n = 13). Diffusion-weighted magnetic resonance imaging using a single-shot echo-planar imaging with a diffusion-weighted factor b of 0, 500, and 1,000 s/mm(2) was done for all patients and volunteers.
