Oval cells constitute an interesting hepatic cell population. They contribute to sustain liver regeneration during chronic liver damage, but in doing this they can be target of malignant conversion and become tumor-initiating cells and drive hepatocarcinogenesis. The molecular mechanisms beneath either their pro-regenerative or pro-tumorigenic potential are still poorly understood. In this stud...

The present study aims to investigate association constants, binding capacity and different thermodynamic parameters of ovalbumin-oleic acid (Oval/OA) conjugate at different temperatures using fluorescence method. Oval/OA conjugate was prepared in a phoshphate buffer solution at different temperatures. The conjugation process resulted in a change of the fluorescence emission intensity. The emis...

Abstract We studied the heat transfer of finned exchanger configurations with a novel design. These fin designs use integrated pins to enhance conduction from base tip as well air-side on surface. Oval tubes conventional circular plain fins (CPF) pin (CIPF) and serrated (SIPF) were additively generated by Selective Laser Melting (SLM) process installed at bottom 6.5 m long chimney. All tested i...

PURPOSE To develop a projection quality-driven tube current modulation method in cone-beam computed tomography for image-guided radiotherapy based on the prior attenuation information obtained by the planning computed tomography and then evaluate its effect on a reduction in the imaging dose. MATERIALS AND METHODS The QCKV-1 phantom with different thicknesses (0-400 mm) of solid water upon it...

Esophageal Development. 1. The region of most active mitosis per mm. of cross-section in the esophagus is the entodermal epithelial tube. The mitotic figures follow a spiral path in the manner of a left-handed helix from the cephalic to the caudal direction. 2. The region of least active growth per mm. of cross-section in the esophagus is the mesenchyme surrounding the epithelial tube. 3. The h...

Bmi1 is a polycomb group transcriptional repressor and it has been implicated in regulating self-renewal and proliferation of many types of stem or progenitor cells. In addition, Bmi1 has been shown to function as an oncogene in multiple tumor types. In this study, we investigated the functional significance of Bmi1 in regulating hepatic oval cells, the major type of bipotential progenitor cell...

Urachal anomalies are exceptionally rare. They can present in different ways in childhood as well as in adults. We present an interesting case of vesico-urachal diverticulum with alternating sinus. The interesting finding in this patient was the inversion and disappearance of the umbilicus at the termination of voiding
