The sedimentation of L1210 nucleoids has been used to demonstrate a hyperthermia-associated increased protein to DNA ratio and an apparent inhibition of processes involved in the restoration of the protein to DNA ratio. The distance of nucleoid sedimentation increased as a function of exposure temperature and exposure time, and was proportional to an(More)
OBJECTIVE To describe onset of syndrome of inappropriate antidiuretic hormone (SIADH) associated with vinorelbine therapy for advanced breast cancer. CASE SUMMARY A 50-year-old white woman with a history of advanced breast cancer refractory to other treatment modalities was receiving vinorelbine. Blood chemistries revealed severely depleted sodium and(More)
Two patients developed intraparenchymal myeloblastomas (granulocytic sarcomas) of the brain. One patient with acute myelogenous leukemia in hematological remission had multiple myeloblastomas in the cerebrum and thalamus. The second patient, who had Philadelphia-chromosome-positive chronic myelogenous leukemia, developed a solitary lesion of the cerebrum(More)
A method was developed for fast and efficient isolation of DNA from formalin-fixed, decalcified, celloidin-embedded human temporal bone sections for subsequent use in polymerase chain reaction (PCR) DNA amplification. The method relies on the use of an enzymatic digestion with proteinase K to release and solubilize the patient's DNA from an individual 20-(More)
The effect of butylated hydroxytoluene (BHT) on adriamycin (ADR)-induced skin ulcers was investigated using rats. The application of BHT reduced the size of the skin ulcers by the following amounts: topical application (20%); intradermal injection (50%); repeated applications of BHT (82%). Additional studies are required to determine if BHT will be a(More)
We report on the individual and combined effects of doxorubicin (DOX) and hyperthermia (HYP) on nucleoid sedimentation and poly (ADP-ribose) polymerase (PARP) activity of L1210 cells. The effects of HYP and DOX on nucleoid sedimentation (increased sedimentation) were similar and correlated with cell viability. No correlation of PARP activity with cell(More)
We report on the individual and combined effects of adriamycin (ADR) and hyperthermia (HYP) on the sedimentation behavior of L1210 mouse leukemia cell nucleoids in neutral sucrose gradients. Nucleoid sedimentation profiles obtained from cells incubated with ADR (1-10 microM; 30 min; 37 degrees C) exhibited an increased sedimentation rate associated with an(More)
Archival temporal bone collections are an invaluable resource for studying the molecular genetics of many types of otopathology. The irreplaceable nature of temporal bone sections makes efficiency of DNA extraction of paramount importance. Several protocols are available for extracting DNA from fresh and preserved tissue. To establish the best protocol for(More)
