Long-term biological effects after acute I-administration of two rat models (with and without thyroid).

Purpose: Radioiodine-131 (RAI or iodine-131) is one of the most frequently used radionuclides for diagnosis and therapy of thyroid diseases (90% of all therapies in nuclear medicine). In order to optimize the patient protection, it is important to evaluate the long-term biological effects of RAI therapy on non-target organs.

Materials And Methods: An experimental animal model has been adopted, it consists on miming RAI therapy.

Local similarity of activity patterns during auditory and visual processing.

Neuroimaging studies have shown that brain activity is variable and changes according to stimuli and the environmental context, reflecting brain coding or information representations at different processing levels. However, little is known about activity organization that reflects coding strategies. Here, we explored and compared two different coding approaches, spatial via cross-correlation and intensity-based coding using mutual information.

Treatment of protoscoleces with gamma radiation: Potential immunoprotective effect against experimental murine echinococcosis.

Cystic echinococcosis (CE) is one of the most important zoonotic diseases with a worldwide distribution. It is caused by the larval stage of the dog tapeworm "Echinococcus granulosussensu lato" and constitutes a major economic and public health problem in several countries. Protoscoleces are one component of this larval stage that can interact with both definitive and intermediate hosts.

Assisted Self-Assembly to Target Heterometallic Mn-Nd and Mn-Sm SMMs: Synthesis and Magnetic Characterisation of [Mn Ln (O) (OH) (mdea) (piv) (NO ) ] (Ln=Nd, Sm, Eu, Gd)*.

In an assisted self-assembly approach starting from the [Mn O (piv) (4-Me-py) (pivH) ] cluster a family of Mn-Ln compounds (Ln=Pr-Yb) was synthesised. The reaction of [Mn O (piv) (4-Me-py) (pivH) ] (1) with N-methyldiethanolamine (mdeaH ) and Ln(NO )  ⋅ 6H O in MeCN generally yields two main structure types: for Ln=Tb-Yb a previously reported Mn Ln motif is obtained, whereas for Ln=Pr-Eu a series of Mn Ln clusters is obtained. Within this series the Gd analogue represents a special case because it shows both structural types as well as a third Mn Ln inverse butterfly motif.

Stimulus-specific information is represented as local activity patterns across the brain.

Modern neuroimaging represents three-dimensional brain activity, which varies across brain regions. It remains unknown whether activity of different brain regions has similar spatial organization to reflect similar cognitive processes. We developed a rotational cross-correlation method allowing a straightforward analysis of spatial activity patterns distributed across the brain in stimulation specific contrast images.
