Renal epithelial cells damaged by ischemia/reperfusion (I/R) can be restored by timely and appropriate treatment. Recent studies have reported that intra renal adult kidney stem cells contribute to the restoration of tubules damaged by I/R. Here, we determined the role of adult tubular cells in the restoration of damaged tubules. We labeled slow cell-cycle cells (SCCs) with 5-bromo-2’-deoxyuridine (BrdU) and investigated their location in the kidneys as well as their contribution to the restoration of tubular cells damaged by I/R injury in mice. Thirty minutes of bilateral ischemia resulted in severe disruption of tubular epithelial cells along with a decline in renal function. The post-ischemic disruption of tubular epithelial cells was most severe in the S3 segment of the outer stripe of the outer medulla. Damaged tubules demonstrated gradual recovery of renal function over time. BrdU-labeled SCCs were mainly observed in tubules located at the junction of cortex and outer medulla, as well as in the inner medulla. The tubular SCCs expressed functional tubule cell markers such as Na/K-ATPase, Na-K-Cl cotransporter-2, and aquaporin 1 and 2. BrdU-labeled SCCs survived I/R injury and proliferated. These results demonstrate that SCCs present in tubules contribute to the restoration of tubular epithelial cells injured by I/R.

<P><B>Abstract</B></P> <P>Structural and electronic modification of titanium oxide (TiO<SUB>2</SUB>) nanomaterials induced by the co-introduction of fully disordered glass phase and oxygen vacancies can lead to remarkable advances in the electrode performance in emerging energy storage systems. We report on the effective co-creation of fully amorphous nanofibers (NFs) composed of black TiO<SUB>2-x</SUB> and conductive carbons throughout the NF structure, and evaluate the materials as potential anodes in sodium-ion batteries. The black TiO<SUB>2-x</SUB> nanofiber is successfully fabricated by electrospinning a precursor solution followed by a two-step sequential thermal treatment in an air and reducing atmosphere. The NF electrode could deliver approximately two-fold higher 2nd discharge capacity and an excellent kinetic performance even under high rates compared to that delivered by anatase-structured white TiO<SUB>2</SUB> NFs used as reference, because of (i) an inherent free volume in the glass phase corresponding to the enlarged Na<SUP>+</SUP> sites, (ii) increased electrical conductivity (low bandgap) resulting from the presence of Ti<SUP>3+</SUP>, (iii) introduction of conductive carbon agents around the TiO<SUB>2-x</SUB> domain, and (iv) one-dimensional NF feature allowing numerous Na<SUP>+</SUP> reaction sites at the electrochemical interface.

Nickel induced crystallization of amorphous silicon (a-Si) has been studied by selective deposition of Ni on a-Si thin films. The kinetics of crystallization for MIC was found to be greatly enhanced than that of SPC. Ni-induced crystallization is a promising technique for low-temperature fabrication of poly-Si thin-film transistors needed for large area applications. Lateral growth of polycrystalline silicon mediated by the formation of nickel silicide, has been successfully employed for the fabrication of high-performance TFTs. A-Si thin films on which Ni films were deposited with various thickness were crystallized as a function of annealing temperatures. Throughout the thesis work, wise choice of both the thickness of Ni and the annealing temperature was found to produce poly-Si films with high quality, thus potentially resulting in the production of TFTs with high performance.

치아종은 치아조직의 비정상적인 과성장으로인해 형성되는 외배엽성 상피세포와 중배엽세포로 구성된 혼합종양이다. 양성 치성 종양 중에서 가장 흔하며 신생물이라기보다 과오종으로 보고 있다. 치아종은 악골내 모든 부위에서 발생할 수 있지만 치아와 유사한 복합 치아종은 비교적 상악 전치부에 호발하고,불규칙한 형태를 나타내는 복잡 치아종은 하악 구치부에 호발한다. 일반적인 증상이 없어 일상적인 방사선 검사에서 주로 발견되며 영구치의 맹출지연이나 매복,유치의 만기잔존 등의 원인이 될 수 있지만 영구치의 선천적 결손을 동반한 증례는 매우 드물다 치료는 외과적 제거가 추천되며 완전한 적출시 재발은 드물다. 본 증례는 영구치의 선천적 결손을 동반한 복합 치아종 환자에 대하여 보고하는 바이다. Odontoma is the most common benign odontogenic tumors, and have been defined as mixed odontogenic tumor composed of epithelial and mesenchymal cells. Odontoma is believed to be hamartomatous rather than neoplastic in nature. The classification by WHO divides odontoma into 2 groups such as complex odontoma and compound odontoma. Compound odontoma comprises dental tissues, resembling the morphology of a tooth and has predilection for the anterior maxilla, In contrast, complex odontoma has unorganized mass, not resembling the normal tooth and has predilection for the posterior mandible. Odontoma is almost asymptomatic, so it is usually found on routine radiographic examination. Common presenting symptom is impacted or unerupted permanent teeth and retained primary teeth, but coexistent odontoma and congenital missing of permanent teeth is a very rare condition. The recommended treatment for an odontoma is conservative surgical excision, with care taken to remove the surrounding soft tissue. This report presents 2 patients with compound odontoma of the mandible who have congenital missing of the permanent teeth.

Multidrug resistance (MDR) of cancer cells is, at least in part, associated with the overexpression of P-gly-coprotein (P-gp). Many studies hve demonstrated that natural compounds obtained from fruits, vegetables, teas and medicinal plants may modulate P-gp activity. The objective of the present investigation was to examine the effect of seven natural compounds on the P-gp activity in human uterine sarcoma cell line, MES-SA/DX5. Daunomycin uptake was significantly increased by biochanin A and silymarin (p<0.0001) whereas it was reduced by morin (p<0.01). The efflux of daunomycin from the cells was significantly inhibited by biochanin A, morin, cephalotaxine, berberine (p<0.05) and silymarin (p<0.0001). Biochanin A, berberine and silymarin significantly decreased IC_(50) value of daunomycin (p<0.05) while morin increased it (p<0.05). These results suggest that some natural compounds such as biochanin A and silymarin may inhibit P-gp funciton and can by developed as MDR reversing agents to improve the efficacy of chemotherapeutic drugs when administered concomitantly.
