Stone Wool Substrate Cover Incision Impacts on the Root-Zone Water Content, Temperature, and Yield of Tomato Cultures.

Standardized cultivation systems are crucial for establishing reproducible agronomic techniques. Especially stone wool-based cultivation is governed by standardized specifications and provides a controllable root-zone environment. However, the effects of stone wool cover incision on root-zone variability have rarely been studied.

Functional neuroimaging of the 6-OHDA lesion rat model of Parkinson's disease.

We characterized the unilaterally 6-hydroxydopamine (6-OHDA)-lesioned rat, a well-known acute model of Parkinson's disease (PD), with [(18)F]-fluoro-2-deoxy-d-glucose (FDG) small-animal positron emission tomography (PET), which we compared with a drug-induced rotation behavioral test. In the 6-OHDA model, significant glucose hypometabolism was present in the primary motor cortex, substantia nigra, and pedunculopontine tegmental nucleus on the ipsilateral side. In contrast, neuronal activations were observed in the primary somatosensory cortex and ventral caudate-putamen area after lesioning.
