It is shown that several (single-mode) models (PTT, XPP) are basically special cases of the general network model. The XPP model [J. Rheol. 45 (2001) 823] is shown to give an identical response to a PTT model at high elongational rates, but the models differ in shear flow at high shear rates. The Giesekus term in the XPP model has practically no effect at any deformation rate except the generat...

Copper sulfide nanoparticles (CuS NPs) have been reported as a single-compartment theranostic nanosystem to visualize and treat tumors simultaneously. However, few studies have investigated the in vivo tumor-targeted delivery of this class of nanoparticles. In this study, we introduced a tumor-specific targeting ligand, folic acid (FA), onto the surface of CuS NPs as a model system to demonstra...

Penile traction therapy (PTT) is a new therapeutic option for men with Peyronie's disease (PD). However, it has a long history of use in other fields of medicine including bone, skin, skeletal muscle, and Dupuytren's. Mechanotransduction, or gradual expansion of tissue by traction, leads to the formation of new collagen tissue by cellular proliferation. As a molecular result, continuous extensi...

Proliferating trichilemmal tumor (PTT) is an uncommon neoplasm arising from the follicular isthmus. Its histological characteristic is the presence of trichilemmal keratinization. PTT usually presents as a solitary nodule on the scalp of elderly women. We describe a case of a PTT on the gluteal region (buttocks) of a 16-year-old female, presenting as a solitary nodule.

A new technique in spring ligament reconstruction using medial half of posterior tibial tendon is demonstrated as a means of supporting the arch. In addition a new concept of double bundle PTT reconstruction based on anatomical attachments of original PTT is presented with the goal of obtaining the full function of PTT.

OBJECTIVES To evaluate a noninvasive measure of arousal, the pulse transit time (PTT), as a screening tool for obstructive sleep apnea/hypopnea syndrome (OSAHS) in an unselected population of symptomatic children, compared with overnight polysomnography (PSG). A secondary objective included comparing the diagnostic performance of PTT with continuous pulse oximetry recorded during PSG. DESIGN ...

Harn et al. proposed a series of Diffie-Hellman key exchange protocols which are integrated into Digital Signature Algorithm in 2004. Recently, Phan pointed out that Harn et al.’s protocols cannot provide forward secrecy and key freshness, which are two standard security attributes that key exchange protocols should have. Phan also gave his improvement. In this paper we present a better improve...

OBJECTIVE To examine the relationship of fasting indicators of insulin sensitivity with a more invasive measure of insulin sensitivity (frequently sampled intravenous glucose tolerance test [FSIVGTT]) and the effect of Tanner stage and ethnicity on that relationship. RESEARCH DESIGN AND METHODS Data were analyzed from 149 overweight girls (97 Hispanic and 52 African American) who were either ...
