BACKGROUND Packing after closed reduction of nasal fracture causes uncomfortable nasal obstruction in patients. We packed the superior meatus with synthetic polyurethane foam (SPF) to support the nasal bone, and packed the middle nasal meatus with a nasal airway splint (NAS) and SPF. The aim of this article is prospectively to compare the subjective patient discomfort of SPF (Nasopore Forte plu...

Previously our novel Shared Potential Field (SPF) method has been introduced and compared against a non-sharing control in both simulation and laboratory settings. In this paper, we compare the SPF against an existing type of robot architecture, a hybrid robotic system. The task given to the multi-robot systems is to traverse an unknown environment, in search of a single target. The metric of p...

Superplastic forming (SPF) is conducted in a heated, pressurized die where direct monitoring of critical SPF parameters is extremely difficult. Numerical models provide a critical means of tracking the forming process, allowing the applied gas pressure to be adjusted to maintain optimum SPF behavior throughout the forming process. This paper describes how the MARC finite element code was used t...

OBJECTIVE We investigated the correlation between ploidy or S-phase fraction (SPF) and the clinical pathological characteristics of patients with peritoneal carcinomatosis from ovarian cancer. We also assessed their relation with the in vivo and in vitro response to several chemotherapeutic agents. PATIENTS AND METHODS Fifty-three patients with peritoneal carcinomatosis from ovarian cancer we...

PURPOSE The purpose of the study was to examine the use of skin from porcine ears as a biological substrate for in vitro testing of sunscreens in order to overcome the shortcomings of the presently used polymethylmethacrylate (PMMA) plates that generally fail to yield a satisfactory correlation between sun protection factors (SPF) in vitro and in vivo. PROCEDURES Trypsin-separated stratum cor...

STUDY DESIGN An in-vitro study. PURPOSE The current study is aimed at investigating the differences in stability between short posterior fixation (SPF), hybrid posterior fixation (HPF), and long posterior fixation (LPF) with and without anterior column augmentation using calcium phosphate bone cement (CaP) for treating burst fractures (BFs). OVERVIEW OF LITERATURE The ideal treatment for th...

Deoxyribonucleic acid (DNA) content of bronchopulmonary neuroendocrine tumours was measured by flow cytometry in order to investigate correlations between ploidy, S-phase fraction (SPF) and two histological classifications (World Health Organization (WHO), Warren and Gould), and clinical staging. A paraffin-embedded technique was used on 20 surgical specimens. Cases comprised (according to the ...

Sunscreen use is recommended for the prevention of sunburn and skin cancer. Little is known regarding sunscreen availability in high versus low income communities. We analyzed sunscreen availability in three large metropolitan counties to determine the relationship between availability and community demographics. We included sun care products in all pharmacies and supermarkets open as of July 2...

We are exposed to millions of microbial and dietary antigens via the gastrointestinal tract, which likely play a key role in type 1 diabetes (T1D). We differentiated the effects of these two major environmental factors on gut immunity and T1D. Diabetes-prone BioBreeding (BBdp) rats were housed in specific pathogen-free (SPF) or germ-free (GF) conditions and weaned onto diabetes-promoting cereal...
