Modulated tone-burst light was employed to measure non-radiative relaxation time of fluorophores with biomedical importance through photoacoustic effect. Non-radiative relaxation time was estimated through the frequency dependence of photoacoustic signal amplitude. Experiments were performed on solutions of new indocyanine green (IR-820), which is a near infrared dye and has biomedical applicat...

In this paper we present the first related-key rectangle cryptanalysis of Rijndael-160/160 and Rijndael-192/192. Our attack on Rijndael-160/160 covers eight rounds. The attack complexities are 2 chosen plaintexts, 2 8-round Rijndael-160/160 encryptions and 2 bytes. Our attack on Rijndael-192/192 covers ten rounds. It requires 2 chosen plaintexts, 2 10-round Rijndael192/192 encryptions and 2 byt...

Lung brachytherapy using high-dose rate (192)Ir technique is a well-established technique of radiation therapy. However, many commercial treatment planning systems do not have the ability to consider the inhomogeneity of lung in relation to normal tissue. Under such circumstances dose calculations for tissues and organs at risk close to the target are inaccurate. The purpose of the current stud...

Farnesoid X receptor (FXR, NR1H4) plays an important role in the regulation of bile acid homeostasis in liver and intestine and may exert protective effects against certain forms of cancer such as colon carcinoma. However, the role of FXR in cell growth regulation, apoptosis, and carcinogenesis is still controversial. Similar to FXR, microRNA-192 (miR-192) is mainly expressed in the liver and c...

We have demonstrated in vitro and in vivo the specific binding of a monoclonal antibody to the rat nerve growth factor (NGF) receptor. Previous work had shown that this antibody, designated 192-IgG, does not compete with NGF for binding to the NGF receptor of PC12 cells, but instead interacts with the receptor to increase NGF binding to PC12 cells (Chandler, C. E., L. M. Parsons, M. Hosang, and...

PURPOSE The purpose of this study is to investigate the molecular mechanism of miR-192 in colon cancer. EXPERIMENTAL DESIGN Human colon cancer cell lines with different p53 status were used as our model system to study the effect of miR-192 on cell proliferation, cell cycle control, and mechanism of regulation. RESULTS Our results show that one of the key miR-192 target genes is dihydrofola...
