Reliability of serial urine HCG as a biomarker to detect early pregnancy loss (2002)

Goldman, M.B., Ryan, L.M., Chen, C., Damokosh, A.I., Christiani, D.C., ...

BACKGROUND: To examine the reliability of HCG as a biomarker for early pregnancy loss, five experienced researchers independently assessed data from 153 menstrual cycles, determining whether each...

Generalized additive distributed lag models: quantifying mortality displacement (2000)

Zanobetti, A., Wand, M. P., Schwartz, J., Ryan, L. M.

There are a number of applied settings where a response is measured repeatedly over time, and the impact of a stimulus at one time is distributed over several subsequent response measures. In the...

A unique ectonucleotide pyrophosphohydrolase associated with porcine chondrocyte-derived vesicles.

Masuda, I, Hamada, J, Haas, A L, Ryan, L M, McCarty, D J

Previous studies have shown increased nucleotide pyrophosphohydrolase (EC 3.6.1.8) (NTPPHase) activity in detergent extracts of degenerated human cartilage containing calcium pyrophosphate dihydrate...

Alkaline phosphatase: placental and tissue-nonspecific isoenzymes hydrolyze phosphoethanolamine, inorganic pyrophosphate, and pyridoxal 5'-phosphate. Substrate accumulation in carriers of hypophosphatasia corrects during pregnancy.

Whyte, M P, Landt, M, Ryan, L M, Mulivor, R A, Henthorn, P S, Fedde, K N, ...

Hypophosphatasia features selective deficiency of activity of the tissue-nonspecific (liver/bone/kidney) alkaline phosphatase (ALP) isoenzyme (TNSALP); placental and intestinal ALP isoenzyme (PALP...

Pyrophosphohydrolase activity and inorganic pyrophosphate content of cultured human skin fibroblasts. Elevated levels in some patients with calcium pyrophosphate dihydrate deposition disease.

Ryan, L M, Wortmann, R L, Karas, B, Lynch, M P, McCarty, D J

In calcium pyrophosphate dihydrate (CPPD) crystal deposition disease, metabolic abnormalities favoring extracellular inorganic pyrophosphate (PPi) accumulation have been suspected. Elevations of...

Varied magnetic field, multiple-pulse, and magic-angle spinning proton nuclear magnetic resonance study of muscle water.

Fung, B M, Ryan, L M, Gerstein, B C

The nuclear magnetic resonance linewidth of 1H in water of frog muscle was studied as a function of magnetic field strength and angle of orientation. The results suggest that the observed spectra are...

A comparison of continuous- and discrete- time three-state models for rodent tumorigenicity experiments.

Lindsey, J C, Ryan, L M

The three-state illness-death model provides a useful way to characterize data from a rodent tumorigenicity experiment. Most parametrizations proposed recently in the literature assume discrete time...

Statistical analysis of disease onset and lifetime data from tumorigenicity experiments.

Lagakos, S W, Ryan, L M

We present and discuss several methods for analyzing rodent tumorigenicity experiments. Two approaches are based on the age and tumor status (present/absent) of each animal at the time of death, and...

Triple crystal disease: monosodium urate monohydrate, calcium pyrophosphate dihydrate, and basic calcium phosphate in a single joint.

Halverson, P B, Ryan, L M

A 49 year old man is described with a polyarticular arthritis. Synovial fluid aspirated from the knee joint showed monosodium urate monohydrate and calcium pyrophosphate dihydrate by polarised light...
