Passage of spermidine across the blood-brain barrier in short recirculation periods following global cerebral ischemia: effects of mild hyperthermia.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Transport of a polyamine (PA), spermidine (SPMD) into rat brain at various early postischemic periods was studied. Rats underwent 20 min of four-vessel occlusion (4VO) followed by 5, 10, 30 and 60 min of recirculation (RC) periods with natural brain temperature. 3H-aminoisobutyricacid (AIB) and

Effect of hyperthermia on spermidine/spermine N1-acetyltransferase activity in Ehrlich ascites cells.

Ingia / Ingia

When Ehrlich ascites tumor cells were incubated at 42 degrees C, the activity of spermidine/spermine N1-acetyltransferase, a rate-limiting enzyme of polyamine biodegradation, decreased to 20% of the control level within 1 hr. Protein synthesis, judged from the incorporation of [3H]leucine into the

Polyamine biosynthesis inhibitors combined with systemic hyperthermia in cancer therapy.

Ingia / Ingia

A Phase I clinical trial has been initiated at the University of Arizona Cancer Center which combines escalating oral doses of the polyamine biosynthesis inhibitor alpha-difluoromethylornithine (DFMO), with systemic hyperthermia (approximately 41.5 degrees C) in the treatment of metastatic melanoma.

Hyperthermia studies in polyamine-altered human lung carcinoma cells.

Ingia / Ingia

The effect of polyamine depletion on the survival response of human lung carcinoma cells (A-549) to acute heating at 45 degrees C and its effect on the induction and decay of thermotolerance were investigated in exponential and plateau-phase cells. A 48-h exposure to 1 mM

Involvement of polyamines in the contragestational effect of hyperthermia.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Although hyperthermia produces teratogenic effects in a great variety of animal species, the molecular mechanisms by which hyperthermia exerts its action remain unknown. We have studied the implications of polyamines in contragestational hyperthermia in rats. Our results show that the

Polyamines and polyamine biosynthesis in cells exposed to hyperthermia.

Ingia / Ingia

The issue of how polyamines act to sensitize cultured cells to the lethal effects of hyperthermia was investigated using Chinese hamster cells which were induced to express thermotolerance. Intracellular levels of these naturally occurring polycations were manipulated in certain situations by

Temporal studies of factors associated with changes in transcription during Q fever.

Ingia / Ingia

Temporal studies were made of factors associated with increased RNA synthesis in guinea pig liver during Q fever. DNA-dependent RNA polymerase activities increased immediately after infection. The major distribution of RNA polymerase classes shifted from class II to class I during infection.

Evidence against putrescine and polyamines as endogenous mediators of fever.

Ingia / Ingia

Endogenous concentrations of putrescine, spermidine, spermine and related biosynthetic enzymes were not affected by the administration of bacterial endotoxin and the subsequent development of fever in rabbits. In addition, the febrile response to endotoxin was unaffected either by the ornithine

Polyamine patterns in plasma of patients with systemic lupus erythematosus and fever.

Ingia / Ingia

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with various clinical manifestations and serologic markers. In this study, we analyzed nine polyamine (PA) profiles of plasma from patients with SLE and healthy controls (HCs), and the relationship between the PA profiles and

Effects of treatments with alpha-difluoromethylornithine and hyperthermia on the growth and polyamine metabolism of Harding-Passey murine melanoma.

Ingia / Ingia

The oral administration of alpha-difluoromethylornithine (DFMO), an enzyme-activated inhibitor of ornithine decarboxylase (ODC), produced a marked decrease in the rate of growth of amelanotic Harding-Passey melanoma transplanted in mice. The half-life of this compound in Harding-Pasey melanoma was

Polyamines, and effects from reducing their synthesis during egg development in the yellow fever mosquito, Aedes aegypti.

Ingia / Ingia

Development of eggs after a blood meal in the yellow fever mosquito Aedes aegypti involves hormonal changes, synthesis of nucleic acids, activation of the digestive enzyme trypsin, and production of the yolk protein vitellogenin. Polyamines have been implicated in growth processes and were here

Ingia / Ingia

"Polyamine patterns in plasma of patients with systemic lupus erythematosus and fever" by Kim et al. provides insight into possible involvement of polyamines in systemic lupus erythematosus (SLE). The authors report decreases in N1-acetylspermidine, spermidine, spermine, and N1-acetylcadaverine and

Biogenic amines in vacuum-packaged and carbon dioxide-controlled atmosphere-packaged fresh pork stored at -1.50 degrees C.
