Quantitative perfusion analysis of transabdominal contrast-enhanced ultrasonography of pancreatic masses and carcinomas.   Gastroenterology, 137(6): 1903-11.

BACKGROUND & AIMS: Preoperative differential diagnosis of pancreatic ductal adenocarcinoma (PDAC) and focal masses in patients with chronic pancreatitis (CP) can be challenging. There are fine differences in the vascularization of these lesions; ultrasound contrast agents can aid in their differentiation. We evaluated the value of software-aided quantitative analysis of transabdominal contrast-enhanced ultrasonography for differential diagnosis of PDAC vs focal masses. METHODS: Sixty ...

Impact of acoustic pressure on ambient pressure estimation using ultrasound contrast agent.   Ultrasonics, 50(2): 294-9.

Local blood pressure measurements provide important information on the state of health of organs in the body and can be used to diagnose diseases in the heart, lungs, and kidneys. This paper presents an approach for investigating the ambient pressure sensitivity of a contrast agent using diagnostic ultrasound. The experimental setup resembles a realistic clinical setup utilizing a single array transducer for transmit and receive. The ambient pressure sensitivity of SonoVue (Bracco, Milano, ...

Influence of genetic background on fluoride metabolism in mice.   J Dent Res, 88(11): 1054-8.

A/J and 129P3/J mouse strains have different susceptibilities to dental fluorosis, due to their genetic backgrounds. This study tested whether these differences are due to variations in water intake and/or F metabolism. A/J (susceptible to dental fluorosis) and 129P3/J mice (resistant) received drinking water containing 0, 10, or 50 ppm F. Weekly F intake, excretion and retention, and terminal plasma and femur F levels were determined. Dental fluorosis was evaluated clinically and by ... [Abstract] [Full-text]

Fluoride sorption by nano-hydroxyapatite/chitin composite.   J Hazard Mater, 172(1): 147-51.

In this study the fluoride adsorption potential of novel nano-hydroxyapatite/chitin (n-HApCh) composite was explored. The sorbent was characterized using FTIR studies. The effects of pH, interfering anions and contact time were studied. The sorption data obtained under optimized conditions were subjected to Langmuir and Freundlich isotherms. Kinetic studies indicate that the rate of sorption of fluoride on n-HApCh composite follows pseudo-second-order and pore diffusion patterns. n-HApCh ... [Abstract] [Full-text]

Fluoride release and cariostatic potential of orthodontic adhesives with and without daily fluoride rinsing.   Am J Orthod Dentofacial Orthop, 136(4): 547-53.

INTRODUCTION: In this study, we aimed to evaluate the fluoride-release profiles and caries lesion development in an enamel model with brackets cemented with 4 orthodontic adhesives with and without daily fluoride exposure. METHODS: Four orthodontic adhesives (Ketac Cem mu, 3M ESPE, Seefeld, Germany; Fuji Ortho LC, GC Corporation, Tokyo, Japan; Light-Bond, Reliance Orthodontic Products, Itasca, Ill; and Transbond XT, 3M Unitek, Monrovia, Calif) were used. Brackets were bonded on bovine enamel ... [Abstract] [Full-text]

Equivalent tamponade by room air as compared with SF(6) after macular hole surgery.   Graefes Arch Clin Exp Ophthalmol, 247(11): 1455-9.

BACKGROUND: To evaluate the effect of tamponade by room air after vitrectomy for the treatment of idiopathic macular hole (MH). METHODS: There were 156 eyes of 151 patients studied. The patients' ages ranged from 35 to 88 years old (mean: 65.1 years). After conventional pars plana vitrectomy with internal limiting membrane peeling, fluid air exchange was performed using 20% SF(6) (Gas group: 91 eyes) or room air (Air group: 65 eyes). Surgical outcomes were retrospectively analyzed. RESULTS: ... [Abstract] [Full-text]

In vitro labeling of mesenchymal stem cells with superparamagnetic iron oxide by means of microbubble-enhanced US exposure: initial experience.   Radiology, 253(1): 153-9.

PURPOSE: To investigate the feasibility of magnetically labeling stem cells with superparamagnetic iron oxide (SPIO) by means of microbubble-enhanced ultrasonographic (US) exposure (MUE) and to study the effects of this approach--without secondary transfection agents--on the viability, proliferation activity, and differentiation capability of MUE-labeled stem cells. MATERIALS AND METHODS: Institutional review board approval was obtained for this study. Human mesenchymal stem cells (MSCs) ([1 to ... [Abstract] [Full-text]
