BACKGROUND It is generally accepted that age-related changes occur in voluntary muscle. Studies of hand grip strength and aging demonstrate a decrease in strength with age; however, there are little data regarding tongue function. The purpose of this study was to determine the relationship of increased age to tongue strength and endurance. METHODS A(More)
A partial amino acid sequence for three different subunits of the iron storage protein, ferritin, has been determined. Ferritin (Mr approximately 480,000) was isolated from porcine spleen and dissociated into its component subunits (Mr approximately 20,000). The subunits, in turn, were separated into three fractions by reversed-phase HPLC. The fractions(More)
OBJECTIVE To compare the outcome of superovulation using clomiphene citrate (CC) versus hMG in conjunction with IUI. DESIGN Sequentially assigned, observational study. Couples initially were assigned to receive either CC or hMG for three cycles. SETTING The Clinical Outpatient Department of the Dartmouth-Hitchcock Medical Center. PATIENT(S)(More)
Lightscanning is a new technique for breast diagnosis. The breast is illuminated with low-intensity light, and the transmission pattern of relatively narrow bands of red and infrared light is detected, amplified, reconstructed, and displayed in visual wavelengths. With a prototype scanner, 1200 patients referred for xeromammography were examined. All(More)
RATIONALE AND OBJECTIVES We devised a prediction rule for estimating pleural effusion volume on the basis of posteroanterior and lateral chest radiographs. METHODS A prediction rule was devised for estimating pleural effusion volume on the basis of the presence or absence of a meniscus on chest radiographs. The rule was tested and validated using separate(More)
To define the relative merits of radiographic and ultrasonic cholecystography, we studied 208 randomly selected patients with possible cholelithiasis. The patients underwent both procedures, and the results were interpreted in blind fashion. Two hundred patients had satisfactory confirmation of their diagnosis, by either a well visualized radiographic(More)
To determine the prevalence, sonographic appearance, and clinical significance of fetal choroid plexus cysts, we analyzed the sonograms and clinical records of 17 fetuses with cysts. Fetal and maternal age, sonographic indication, cyst size and multiplicity, and evolution on serial studies were recorded. Fetal outcome was available in 16 cases by genetic(More)
Insulin from an elasmobranch, the spiny dogfish (Squalus acanthias) has been purified to near homogeneity by means of acid-ethanol extraction and salt precipitation. The amino acid sequences of the performic-acid-oxidised A and B chains have been determined and exhibit some unusual features. The A chain contains a total of 22 amino acids; only the insulin(More)
