Abstract:
Research on Morphology and genesis of the Great Lakes Basin in western Mongolia were taken relatively rarely in recent years. The present study combines the results of previous work with modern analysis of photographs and satellite images. The theory of Pleistocene glaciation which took vast areas of the northern hemisphere became the basis of the new approach. Glaciation covered the area from northwestern Mongolia to Mongolian Altai, Khangai and Khuvsgul mountain ranges. At that time, the ice sheet has also taken the Great Lakes basin area, which was characterized by morphology inherited from

RÉSUMÉLe relief du centre de la Gaspésie septentrionale a grandement été modifié au cours des événements glaciaires du Quaternaire, mais l'érosion glaciaire s'est montrée très sélective. Les éléments du paysage les plus touchés sont les vallées et, dans une moindre mesure, les escarpements séparant les plateaux. Les vallées ont été surcreusées dans leur partie aval, parfois même sous le niveau de la mer. De plus, elles ont été calibrées et élargies, ce qui s'est traduit par l'apparition de parois abruptes, d'éperons tronqués et de vallées affluentes suspendues. Par ailleurs, la majorité des va

Abstract:
Amazonia and the Guianas possess exceptional potential for ethnoarchaeological studies because of the precolumbian heritage of modern-day Amerindian people. Surprisingly, minimal scholarship of this nature has been conducted in the South American lowlands. On the French Guiana coast, Maillard, a small Palikur village, was abruptly abandoned in 1990. I initiated an ethnoarchaeological study to pinpoint important differences between the interpretation of archaeological and ethnographic data. I recorded the topography of features and remains, compiled an inventory of artifacts and the contents of

Abstract:
AbstractTransmission electron microscopy (TEM) with low-energy electrons has been recognized as an important addition to the family of electron microscopies as it may avoid knock-on damage and increase the contrast of weakly scattering objects. Scanning electron microscopes (SEMs) are well suited for low-energy electron microscopy with maximum electron energies of 30 keV, but they are mainly used for topography imaging of bulk samples.

Abstract:
Anisotropic gap junctional coupling is a distinct feature of astrocytes in many brain regions. In the lateral superior olive (LSO), astrocytic networks are anisotropic and oriented orthogonally to the tonotopic axis. In CaV1.3 knock-out (KO) and otoferlin KO mice, where auditory brainstem nuclei are deprived from spontaneous cochlea-driven neuronal activity, neuronal circuitry is disturbed. So far it was unknown if this disturbance is also accompanied by an impaired topography of LSO astrocyte networks. To answer this question, we immunohistochemically analyzed the expression of astrocytic con

Abstract:
Topographic maps are a brain structure connecting pre-synpatic and post-synaptic brain regions. Topographic development is dependent on Hebbian-based plasticity mechanisms working in conjunction with spontaneous patterns of neural activity generated in the pre-synaptic regions. Studies performed in mouse have shown that these spontaneous patterns can exhibit complex spatial-temporal structures which existing models cannot incorporate. Neural field theories are appropriate modelling paradigms for topographic systems due to the dense nature of the connections between regions and can be augmented

Abstract:
AbstractParkinson’s disease (PD) is the second most common neurodegenerative disease worldwide and presents pathologically with Lewy pathology and dopaminergic neurodegeneration. Lewy pathology contains aggregated α-synuclein (αSyn), a protein encoded by the SNCA gene which is also mutated or duplicated in a subset of familial PD cases. Due to its predominant presynaptic localization, immunostaining for the protein results in a diffuse reactivity pattern, providing little insight into the types of cells expressing αSyn. As a result, insight into αSyn expression-driven cellular vulnerability ha

Abstract:
Upregulation of the proto-oncogene TCL1A is causally implicated in various B-cell and T-cell malignancies. High-level TCL1A correlates with aggressive disease features and inferior clinical outcomes. However, the molecular and cell-biological consequences of, particularly nuclear, TCL1A are not fully elucidated. We observed here in mouse models of subcellular-site specific TCL1A-induced lymphomagenesis, that TCL1A exerts a strong transforming impact via nuclear topography. In proteomic screens of TCL1A-bound molecules in CLL cells and B-cell-lymphoma lines, we identified regulators of cell cyc

Abstract:
Efficient sensory processing of spatial information is facilitated through the organization of neuronal connections into topographic maps of space. In integrative sensory centers, converging topographic maps must be aligned to merge spatially congruent information. The superior colliculus (SC) receives topographically ordered visual inputs from retinal ganglion cells (RGCs) in the eye and layer 5 neurons in the primary visual cortex (L5-V1). Previous studies suggest that RGCs instruct the alignment of later-arriving L5-V1 inputs in an activity-dependent manner. However, the molecular mechanism
