Zusammenfassung In Nordwestdeutschland zeigten neun Grundwasserkörper einen „schlechten“ chemischen Zustand nach Wasserrahmenrichtlinie aufgrund von Cadmiumkonzentrationen über 0,5 µg/l. Dünger- und Bodenanalysen, sowie Grundwasseranalysen des landesweiten Monitorings dienten der Quantifizierung Cd-Belastung Identifikation Ursachen, wobei geogener Eintrag, Düngeremissionen atmosphärische Deposi...

Purpose: Antibody-drug conjugates (ADCs) provide specific delivery of potent toxins to cancers. Unfortunately, the clinical benefits these powerful therapeutics have not been realized in glioblastoma (GBM). The blood brain barrier (BBB) GBM can limit distribution ADCs into tumor tissue. To bypass BBB, we tested convection enhanced (CED) infusion orthotopic patient derived xenografts. Methods: T...

The transcription factor SOX2 has many established roles in neural development but is generally considered to have limited activity in the adult brain. As part of a study of neuronal phenotypes in the adult rodent hypothalamus, we have now used immunohistochemical analysis to investigate the expression of SOX2 in the adult rat and mouse hypothalamus. Our analysis has revealed that SOX2 protein ...

Neurosteroids are involved in the pathogenesis of hepatic encephalopathy (HE). This study evaluated the effects of finasteride, inhibitor of neurosteroid synthesis, on motor, EEG, and cellular changes in rat brain in thioacetamide-induced HE. Male Wistar rats were divided into the following groups: 1) control; 2) thioacetamide-treated group, TAA (300 mg·kg(-1)·day(-1)); 3) finasteride-treated g...

As research into periventricular leukomalacia (PVL) gradually increases, concerns are emerging about long‑term neuron injury. The present study aimed to investigate neuronal injury and the relevant alterations in apoptosis and autophagy in a PVL model established previously. A rat model of hypoxia‑ischemia‑induced PVL was established. In the model group, Sprague‑Dawley (SD) rats [postnatal day ...

Aromatic L-amino acid decarboxylase (AADC) is an essential enzyme in the synthesis of serotonin, dopamine, and certain trace amines and is present in a variety of organs including the brain and spinal cord. It is previously reported that in mammalian spinal cord AADC cells (called D-cells) were largely confined to a region around the central canal and that they do not produce monoamines. To dat...

The 6-Hydroxydopamine (6-OHDA) rat model of Parkinson's disease is essential for a better understanding of the pathological processes underlying the human disease and for the evaluation of promising therapeutic interventions. This work evaluated whether a single striatal injection of 6-OHDA causes progressive apoptosis of dopamine (DA) neurons and activation of glycogen synthase kinase 3β (GSK-...

Background Glehnia littoralis has been used for traditional Asian medicine, which has diverse therapeutic activities. However, studies regarding neurogenic effects of G. littoralis have not yet been considered. Therefore, in this study, we examined effects of G. littoralis extract on cell proliferation, neuroblast differentiation, and the maturation of newborn neurons in the hippocampus of adul...

Parkinson's disease is a neurodegenerative disorder of the substantia nigra accompanied by the depletion of dopamine levels. Symptoms of Parkinson's disease involve motor disorders, including dysphagia and aspiration. In this study, rats were injected with 6-hydroxydopamine (6-OHDA) in order to assess the eating disorder and evaluate the effect of transplantation of neural progenitor cells (NPC...
