Both infection with the human immunodeficiency virus type 1 (HIV) and zidovudine (formerly called azidothymidine [AZT]) cause myopathy. To identify criteria for distinguishing zidovudine-induced myopathy from that caused by primary HIV infection, we reviewed the histochemical, immunocytochemical, and electron-microscopical features of muscle-biopsy(More)
The authors report on a technique for the treatment of symptomatic, chronic complete dislocations of the acromioclavicular joint. The coracoacromial ligament is substituted for the coracoclavicular ligaments, and a special temporary coracoclavicular lag screw is used to stabilize the clavicle to the coracoid during ligament healing. The technique has been(More)
Hydatidiform moles (HMs) are classified as partial or complete based on a combination of gross, histologic, and karyotypic features. Adherence to strict and reproducible diagnostic criteria is needed to ensure accurate diagnosis and minimize interpathologist variability. Using the kappa statistic as a measure of agreement, the morphologic, flow cytometric,(More)
Five anesthetized dogs undertook a chamber dive, on air, to 300 feet of seawater for 15 min. After the dive, spinal cord decompression sickness was detected by recording a reduced amplitude of the somatosensory evoked potential compared with predive base-line values. After the diagnosis of decompression sickness and rapid perfusion fixation of the animal,(More)
The goal of this study was to determine if deoxyribonucleic acid (DNA) flow cytometric and quantitative histological parameters could predict occult metastases in clinical stage I nonseminomatous testicular cancer. Archival paraffin primary tumor tissue was available from 36 clinical stage I nonseminomatous germ cell testicular cancer patients who all had(More)
A study was conducted to determine the effect of transportation stress on ovarian function in superovulated heifers. Thirty cyclic Hereford heifers of similar age and weight and in good body condition were randomly assigned to control and stress-treated groups. All animals received two daily injections of 5 mg follicle stimulating hormone (FSH) for 4 d(More)
A major challenge in ecotoxicology is to understand the effects of multiple toxicants on organisms. Here we assess the effects on survival, weight change, cocoon production and metabolism caused by exposure to two similarly acting (imidacloprid/thiacloprid) and two dissimilarly acting (chlorpyrifos/Nickel) chemicals on the earthworm Lumbricus rubellus. We(More)
ABSTRACT Six herbicides were evaluated for their effects on Pythium root rot and growth of sugarcane in greenhouse experiments and on in vitro mycelial growth rate of Pythium arrhenomanes. Pendimethalin and atrazine were most inhibitory to mycelial growth, but neither reduced root rot severity. Asulam, atrazine, and metribuzin were not phytotoxic to(More)
BACKGROUND Ovarian serous tumors of low malignant potential (STLMP) occasionally progress; a small percentage of patients die of the tumor. There is no known way to predict which tumors will progress. METHODS Forty STLMP were analyzed by DNA flow cytometry and compared with 26 serous carcinomas. RESULTS Forty percent of Stage I STLMP and 40% of Stage(More)
Superovulated beef cows and heifers were nonsurgically collected 6 to 8 days post estrus. Commercial production results for 1976 through 1978 were 4979 pregnancies from 7814 embryos transferred for an overall pregnancy rate of 63%. In 1978, 519 superovulation procedures averaged 9.95 +/- 8.4 (S.D.) ova collected, 8.2 +/- 7.55 ova fertilized, 5.96 +/- 5.37(More)
