OCT1-mediated cellular drug uptake and interactions between drug transport and drug metabolism
(2012-12-07)OCT1 is a polyspecific organic cation transporter belonging to the solute carrier gene family SLC22. Human OCT1 is mainly expressed on the sinusoidal membrane of hepatocytes and thus may play an important role in ... -
Odor Modulation of Electrical and [Ca<sup>2+</sup>]i Activities in Neurons of the Olfactory Bulb
(2006-07-10)The olfactory bulb is the first relay stage that processes input from the sensory periphery and relays the information to many high-ordered cortical regions. Despite stimulus activity has ... -
Olfactory neurogenesis during tissue maintenance and repair
(2018-06-12)During metamorphosis, the African clawed frog Xenopus laevis undergoes a fundamental transformation from a fully aquatic larva to a secondarily aquatic adult. This extensive habitat change requires major adaptations including ... -
Oligodendroglial anillin facilitates septin assembly to prevent myelin outfoldings
(2019-02-25)Myelination of axons facilitates rapid and precise impulse propagation in the nervous system and thus, normal motor, sensory, and cognitive capabilities. In the central nervous system (CNS), myelin is formed by oligodendrocytes, ... -
On the chloride dependence of vesicular glutamate transport
(2010-06-10)Neurons release neurotransmitters in discrete amounts, the quanta. The transmitters are stored in small membrane-bound organelles, the synaptic vesicles, in the vicinity of the plasma ... -
On the pathophysiological significance of CD154/CD40-mediated leukocyte-endothelial cell interaction
(2003-05-22)CD154/CD40 interactions play a pivotal role in both humoral and cellular immune responses. Their involvement in the pathogenesis of chronic inflammatory bowel disease (IBD) has been revealed by increased expression of ... -
On the role of sugar compartmentation and stachyose synthesis in symplastic phloem loading
(2002-03-08)Compartmentation of phloem-translocated carbohydrates and localization of the synthesis of one specific transport form, stachyose, was studied in leaves of symplastic phloem loaders. In ... -
On ultrastructure and gene expression during epiblast morphogenesis and axial differentiation in the prestreak embryonic disc of the pig
(2021-09-16)The epiblast of the amniote embryo is of paramount importance during early development as it gives rise to all tissues of the embryonic proper. In most mammals, the epiblast emerges by segregation of the inner cell mass ... -
One-step RESOLFT with a positively switchable RSFP with improved deactivation kinetics
(2020-10-01)Interaction and spatial organization of subcellular structures within living cells are an essential aspect of biological research, but conventional microscopy can elucidate these properties only to a finite extent as it is ... -
Onkogenomische Aspekte Zytokin-assoziierter Signaltransduktion
(2009-01-21)In lymphoma patients current therapeutic regimen are associated with a high toxic burden as well as the development of therapy-associated secondary malignancies. Moreover, risk factors ... -
Optical Analysis of [Ca<sup>2+</sup>]i and Mitochondrial Signaling Pathways: Implications for the Selective Vulnerability of Motoneurons in Amyotrophic Lateral Sclerosis (ALS)
(2009-01-21)Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by selective loss of a defined motoneurons (MNs) population in the brain stem and spinal cord of ... -
Optimization of experimental procedures for the assessment of auditory cognition in non human primates
(2024-02-23)In a loose sense, the exceptional development of technology in the past three decades has allowed researchers to drastically improve the quality and quantity of behavioral data. However, the methodological advances achieved ... -
Optimization of temporal parameters of repetitive transcranial magnetic stimulation to improve its efficacy
(2020-08-03)This thesis focused on the effects of changing temporal organization of rTMS whether within the protocol by examining the effects of inter train intervals on the efficacy of rTMS protocols in the first paper (Halawa et al. ... -
Optogenetic Manipulation of the Auditory System
(2021-12-14)There are millions of people who are affected from sensorineural hearing loss. In this type of deafness, sensory hair cells are typically dysfunctional or lost, and thereby not conveying sound information to brain. The ... -
Organic-rich shales as archive and resource for microbial extremophiles
(2021-09-10)Organic-rich shales of sedimentary basins are the most abundant carbon-rich rocks throughout the world, formed as a consequence of different geological events. The repetitive sedimentation of the mudstones, clay particles, ... -
Oribatid mite community structure and trophic ecology along a forest land-use gradient: effect of dead wood, time and root-trenching
(2016-10-26)Oribatid mites are involved in decomposition processes, formation of soil structure and nutrient cycling in most soils worldwide. The main habitats of oribatid mites are litter and soil but they also occur numerously on ... -
Origin and regulation of soil N<sub>2</sub>O and NO<sub>x</sub> fluxes from coniferous and deciduous temperate forests exposed to chronic high N depositions
(2012-02-01)Nitrogen (N) cycling in Europe and in many other parts of the world has been massively accelerated as a result of agricultural and industrial activities in the last decades. As a consequence, ... -
