An analysis of 79 underwater photographs of Manta birostris gathered over a period of nine years in a marine protected area in southeastern Brazil suggests a high predictability of manta ray occurrences in the region during the austral winter (June–September). The reasons for this are probably related to the seasonal oceanographic conditions, as(More)
Hypertrophy of the masticatory muscles is characterized by generalized enlargement of the muscular tissue that affects the facial esthetic and may or not be accompanied by pain [1-3]. This condition can be congenital, but more often it is acquired. The origin has been attributed to muscle hyperactivity and parafunctionsoriginated from stressful lifestyle(More)
A neutron tomography (NT) facility was installed at the IEA-R1 nuclear research reactor of the Nuclear and Energy Research Institute IPEN-CNEN/SP. According to the determined operational characteristics, the time spent to obtain a complete tomography is 4,000s at a neutron flux of 1×10(6) ncm(-2)s(-1) and the best achievable spatial resolution in the image(More)
To assess whether interferon beta1a (IFNbeta1a) therapy affects plasma lipoprotein metabolism, twelve patients with relapsing-remitting multiple sclerosis (MS) were studied during a two-year follow-up period. High density lipoprotein (HDL2) cholesterol and the HDL2/HDL3 ratio were increased at year 2 and lipoprotein (a) was transitorily increased at year 1,(More)
A new facility for neutron tomography has been installed at the IEA-R1 nuclear research reactor of IPEN-CNEN/SP. A tomography can be obtained in 400 s and the spatial resolution in the image is 263 μm. The neutron dose per tomography, in the video camera used for image capture, is only 21 μSv, assures very few damages in its CCD sensor. Some selected(More)
BACKGROUND AND PURPOSE The influence of apolipoprotein E (ApoE) polymorphism on clinical severity of multiple sclerosis (MS) is still controversial. Cigarette smoking has been suggested to influence the progression of disability in these patients. In this study, we aimed to investigate whether an interaction of smoking with the ApoE polymorphism influences(More)
