Squalene epoxidation of microsome-associated squalene is stimulated by a soluble protein termed "supernatant protein factor" (SPF) (Saat, Y. A., and Bloch, K. E. (1976)J. Biol. Chem. 251, 5155-5160). In the absence of SPF, the initial rate for microsome-bound squalene epoxidation is rapid for 5 to 10 min but falls off sharply thereafter. SPF does not affect the rapid initial epoxidation rate of...

The fractions of tumor cells in S phase (DNA synthesis) were measured by in vitro thymidine labeling and autoradiography in 48 breast carcinomas after relapse. The S-phase fractions (SPF's), expressed as S-phase cells/100 cells, had a lognormal distribution with a geometric mean of 6.5 and a median of 7.4. Paired SPF measurements on the primary and relapsed breast carcinomas of 14 patients show...

We instrumented a combined fluorescence spectroscopy and imaging system to characterize the single- and two-photon excited autofluorescence in epithelial tissue. Single-photon fluorescence (SPF) are compared with two-photon fluorescence (TPF) measured at the same location in epithelial tissue. It was found that the SPF and TPF signals excited at corresponding wavelengths are similar in nonkerat...

BACKGROUND The behaviour of colorectal carcinomas may depend on molecular properties of tumors. In node-positive colon cancer, we assessed the S-phase fraction (SPF) index, the vascular endothelial growth factor (VEGF) expression and the TS levels. The combined analysis of SPF/VEGF was studied for predictivity of recurrent disease, the TS quantitation was related to the efficacy of fluorouracil...

BACKGROUND Despite improvements in diagnosis and therapy of oral and oro-pharyngeal carcinomas during the past 30years the 5-year disease-free survival is still poor. Patient's prognosis is affected by cervical lymph node metastasis rather than primary tumors. The DNA ploidy and S-phase fraction (SPF) are associated with tumor aggressiveness and patient outcome in many solid tumors. PURPOSE A...

We found seroprevalences for hepatitis E virus (HEV) of 7.5%, 18.5%, and 83.3% in specific pathogen-free (SPF) laboratory rabbits, monkeys, and pigs, respectively, in China. HEV RNA was detected in 4.8% of SPF rabbits, and 11 rabbits had latent infections. Screening for HEV in SPF animals before relevant experiments are conducted is recommended.

Article history: Received on: 06/07/2013 Accepted on: 19/07/2013 Available online: 30/08/2013 The objective of this study was to develop sunscreen cream formulations with high sun protection factor (SPF) and satisfied characteristics. The actives were anisotriazine (an organic UV filter) and titanium dioxide (an inorganic UV filter). Two optimal cream bases selected from several preliminary for...

A consecutive series of 99 untreated patients undergoing radical surgical resection for stage I-IV laryngeal carcinomas has been studied prospectively. Our purpose was to analyze the predictive relevance of proliferative variables studied [proliferating cell nuclear antigen (PCNA) expression, volume-corrected mitotic (M/V) index, and S-phase fraction (SPF)] on clinical outcome in relation to DN...

The sun protection factor (SPF) of sunscreens is determined by a testing protocol that specifies a sunscreen application rate of 2 mg/cm(2) on the skin. Most people, for cosmetic and economic reasons, only apply enough sunscreen to achieve an SPF of about a third or even a quarter of the level stated on the product. To increase public awareness of the problem, manufacturers could be required to...
