Purpose. To investigate the specific role of Pinin (Pnn) in the development of anterior eye segment in mice. Methods. Conditional inactivation of Pnn in the developing surface eye ectoderm and lens was achieved by creating mice carrying a Pnn null and a floxed Pnn allele as well as a Pax6-Cre-GFP (Le-Cre) transgene. The resultant Pnn conditional knockout(More)
Arteriovenous malformation (AVM) refers to a vascular anomaly where arteries and veins are directly connected through a complex, tangled web of abnormal AV fistulae without a normal capillary network. Hereditary hemorrhagic telangiectasia (HHT) types 1 and 2 arise from heterozygous mutations in endoglin (ENG) and activin receptor-like kinase 1 (ALK1),(More)
Recent advances in nanotechnology have enabled the development of nanoscale sensors that outperform conventional biosensors. This review summarizes the nanoscale biosensors that use aptamers as molecular recognition elements. The advantages of aptamers over antibodies as sensors are highlighted. These advantages are especially apparent with electrical(More)
The RFID (radio frequency identification) is a technology that automatically identifies objects containing the electronic tags by using radio frequency. In RFID system, the reader needs the anti collision algorithm for fast identifying all of the tags in the interrogation zone. This paper proposes the tree based anti collision algorithm using parity bit(More)
In radio frequency identification (RFID) system, the reader needs the anti-collision algorithm for fast identifying all of the tags in the interrogation zone. This paper proposes the tree-based ID prediction algorithm (IPA) to arbitrate the tag collision. For IPA, the count-bits, which represents the number of bit '1's in the ID, are added to the left(More)
Transplantation of neural stem cells has been reported as a possible approach for replacing impaired dopaminergic neurons. In this study, we tested the efficacy of early-stage human dental papilla-derived stem cells and human brain-derived neural stem cells in rat models of 6-hydroxydopamine-induced Parkinson's disease. Rats received a unilateral injection(More)
Hereditary Hemorrhagic Telangiectasia (HHT) is a genetic vascular disease in which arteriovenous malformations (AVMs) manifest in skin and multiple visceral organs. HHT is caused by heterozygous mutations in endoglin (ENG), activin receptor-like kinase 1 (ALK1), or SMAD4. ALK1 regulates angiogenesis, but the precise function of ALK1 in endothelial cells(More)
The GacS/GacA system in the root colonizer Pseudomonas chlororaphis O6 is a key regulator of many traits relevant to the biocontrol function of this bacterium. Proteomic analysis revealed 12 proteins were down-regulated in a gacS mutant of P. chlororaphis O6. These GacS-regulated proteins functioned in combating oxidative stress, cell signaling,(More)
