  • Urine concentrating mechanism modelling in rat kidney inner medulla

    Physicians use charts that are prepared by experiments on animals or humans to prescribe drug dosage for patients. This method requires some precious amount of time by the Ministry of Health to approve new drugs to be used in healthcare centers. Three-dimensional modeling of the inner medulla by considering the known physiological features help us to predict the distribution of a drug or any minerals in the kidney. In this study we present modeling of the important species distribution including Na<sup>+</sup> and urea in the rat inner medulla that influence the urine concentrating mechanism. We use a C++ code to develop the inner medulla geometry based on physiological data to better capture the concentrating mechanism. Features such as tubules variable diameters, pre-bend length and tubules' lateral distance relations have been considered in generating the geometry. Next, a CFD study is done to simulate the concentration of urea and Na<sup>+</sup> along the corticomedullary axis using boundary conditions from the previous study on outer medulla for the inner medulla base. Results show a dramatic increase in concentration of the collecting ducts near the tip of the papilla. Concentration of urea and Na<sup>+</sup> in the interstitium along the corticomedullary axis at different segments demonstrate an analogous pattern to the three-dimensional position of the different types of tubules with respect to each other that indicates the significance of the three-dimensional modeling in this simulation.

  • Calculation of Renal, Cortex and Medulla Volumes using Semi Automated Method

    It is assume that renal volume with cortex and medulla volumes are related with recovery of the kidney after transplantation. In this study it is aim that a semi automated method is developed for renal volumes. Theise volumes can be obtaine with some tools in the developed interface. We used 10 kidneys of 5 donors in this study. The first outputs of the method were compared to the tuned ones and it is found that the first outputs are very close to the corrected contours. Volume error rates were obtained as 0.62%±0.01 for total renal volume, 1.26%±0.01 for cortex volume and 1.23%±0.01 for medulla volume.

    Image-based functional analysis of the kidney plays an increasingly important role in the clinical application. Efficiently and accurately segment the renal cortex and the medulla in MR images will be very helpful for doctor's clinical diagnosis. This paper proposed a semi-automatic segmentation method of renal cortex and medulla based on dynamic magnetic resonance (MR) images of pigs. This segmentation method includes the 3D registration, subtraction and the amendment by using morphology method. The accuracy and precision of the segmentation method on dynamic MR images were evaluated by 11 model pigs. The correlation of renal cortex segmentation result between our method and manual method from doctor in 15 kidneys was 0.9874, while the correlation of signal intensity of the segmented result was 0.9901. Besides, it took less than 1 minute to segment three phases of renal cortex, compared to 20 minutes for manual segmentation. Moreover, by using our semi-automatic segmentation method, we can extract the renal cortex from non-contrast scan images.

The outlines are retrieved by referring to a suitable geometric model of the generic femoral cross section; the projection function derived from such a model is fitted on the grey level values corresponding to the rows of the digitised radiographic image by means of a least squares algorithm. The resulting outlines are used in a software system performing hip prosthesis preoperational planning.

  • Complexity measures of the central respiratory networks during wakefulness and sleep in piglets

    In this study, we examine EMGdi complexity before and after general (muscimol) inhibition of respiratory neurons within the rostral ventral medulla (RVM). We inserted a microdialysis guide tube into the RVM region, allowing us to dialyze muscimol on a daily basis during experiments. Animals were studied using the technique of barometric plethysmography, allowing us to measure ventilation without restraint. The EMGdi signals were recorded from 5 unanesthetized, chronically instrumented and intact piglets (3-10 days old) during eupnea before and after general inhibition of respiratory neurons in the RVM and analyzed using the approximate entropy and fractal analysis methods. Ten consecutive breaths were taken after 6 continuous minutes of unequivocal wakefulness, 3 minutes of NREM and 1 minute of REM sleep. Once the control responses to room air were measured, we dialyzed muscimol. GABA<sub>A</sub> agonist (10mM) into the RVM and repeated in room air. Note that muscimol is an nonspecific inhibitor and inhibits the neurons in the RVM. The EMGdi signals were recorded from 4 unanesthetized, chronically instrumented piglets (3-10 days old) during eupnea and analyzed using the expectation-maximization (EM) fractal method as in the first set of experiments, The complexity values in NREM were reduced more by the inhibition than were the awake stage. However, the changes in the complexity values due to the inhibition of the RVM were much more prominent during REM. The differences in the complexity measures of EMGdi before and after muscimol dialysis were statistically significant (p&lt;0.01) during REM and NREM, but not during wakefulness. Our findings show that inhibition of the RVM reduced the complexity of the respiratory patterns significantly (p&lt;0.05) during NREM and REM sleep stages. These data indicate that the RVM plays an important role in both the control of sleep and the sudden infant death syndrome (SIDs).

  • Processing of retinal signals in the Limulus brain

    Limulus retina sends signals to the brain through optic nerve fibers with processes terminating in both the first and second optic ganglia, called lamina and medulla. At the lamina, OFF signals are generated and sent to the medulla. Medullar cells extend fibers to the other parts of the brain. To understand the neural mechanisms of their visual guided mating behavior, it is important to investigate responses in the medulla. However, there are only very few studies on medulla due to experimental difficulties. In this paper, we developed two experimental setups to study the medulla ex vivo and succeeded in recording responses and in mapping receptive fields. Responses of neurons share many features with responses of ganglion cells in vertebrate retina. The recorded neurons can be classified as non-spiking, sustained and transient ON, sustained and transient OFF, ON-OFF, inhibition, and bilateral and contralateral types. Their receptive fields vary from 6 degrees to more than 180 degrees. Some cells have receptive fields classified as ON-center and OFF-center. In addition, one medullar cell had a separated receptive field extending over 90 degrees in the horizontal direction.

  • 3D Fast Automatic Segmentation of Kidney Based on Modified AAM and Random Forest

    In this paper, a fully automatic method is proposed to segment the kidney into multiple components: renal cortex, renal column, renal medulla and renal pelvis, in clinical 3D CT abdominal images. The proposed fast automatic segmentation method of kidney consists of two main parts: localization of renal cortex and segmentation of kidney components. In the localization of renal cortex phase, a method which fully combines 3D Generalized Hough Transform (GHT) and 3D Active Appearance Models (AAM) is applied to localize the renal cortex. In the segmentation of kidney components phase, a modified Random Forests (RF) method is proposed to segment the kidney into four components based on the result from localization phase. During the implementation, a multithreading technology is applied to speed up the segmentation process. The proposed method was evaluated on a clinical abdomen CT data set, including 37 contrast-enhanced volume data using leave-one-out strategy. The overall true-positive volume fraction and false-positive volume fraction were 93.15%, 0.37% for renal cortex segmentation; 83.09%, 0.97% for renal column segmentation; 81.92%, 0.55% for renal medulla segmentation; and 80.28%, 0.30% for renal pelvis segmentation, respectively. The average computational time of segmenting kidney into four components took 20 seconds.
