Introduction: Since Curcuma longa extract and curcumin have been shown to be potent antioxidant agents, they were used in cultured adult mouse spinal cord slices to investigate whether they can inhibit apoptosis in motor neurons. Methods: Slices from the thoracic region of adult mice spinal cord were divided into four groups: 1. Freshlyprepared slices (time 0) 2. Control 3. Slices treated by cu...

AIM Isolated papillary muscles and enzymatically dissociated myocytes of guinea-pig hearts are routinely used for experimental cardiac research. The aim of our study is to investigate adult mammalian ventricular slices as an alternative preparation. METHOD Vibratome cut ventricular slices (350 microm thick) were examined histologically and with 2-photon microscopy for fibre orientation. Intra...

Ion currents such as M-currents (I(M)), persistent sodium currents (I(NaP)) and H-currents (I(h)) have been observed in a variety of brain regions, including the hippocampal formation, where storage and retrieval of information are facilitated by oscillatory network activities. They have been suggested to play an important role in neuronal excitability, synaptic transmission, membrane oscillato...

Understanding how neuromodulators influence synaptic transmission and intrinsic excitability within the entorhinal cortex (EC) is critical to furthering our understanding of the molecular and cellular aspects of this region. Organotypic cultures can provide a cost-effective means to employ selective molecular biological strategies in elucidating cellular mechanisms of neuromodulation in the EC....

restricted to the dirty slices. It is almost the 2-dimensional mesh considered in Section 2. The diier-ence is that 2r + 2 leftmost and rightmost columns do not contain connections which correspond to Odd-Even Transposition Sort. Additionally, there are columns in the middle of the mesh that contain comparators implementing vertical comparisons in vertical slices. However, using Proposition 1.9...

This paper presents a low memory implementation of efficient lossy volumetric medical image compression using the Set Partitioning in Hierarchical Trees (SPIHT) algorithm. The coding units in this three-dimensional wavelet transform and compression method are short sequences of horizontal stripes cut from the sequence of slices in the volumetric image. As the compression degree increases, the b...

A new approach is proposed to evaluate the non-limit active earth pressure in c–? soil based on horizontal slices method and limit equilibrium method, which takes into account arching effect, displacement, mobilized friction angle, tension cracks, shear stress of layer. The accuracy was demonstrated by comparing experimental results other theoretical methods. comparison showed that appropriate ...

Creating geometric abstracted models from image-based scene reconstructions is difficult due to noise and irregularities in the reconstructed model. In this paper, we present a geometric modeling method for noisy reconstructions dominated by planar horizontal and orthogonal vertical structures. We partition the scene into horizontal slices and create an inside/outside labeling represented by a ...

The lateral nucleus of the amygdala is the entry point of most sensory inputs into the amygdala. However, the way information is processed and distributed within the lateral nucleus still eludes us. To gain some insight into this issue, we have examined the spatial organization of excitatory and inhibitory connections in the lateral nucleus. To this end, we performed whole-cell recordings of pr...
