To study the effects of total-body hyperthermia (TBH) on metastases from malignant tumors, Lewis lung carcinoma (LLC)-bearing C57BL/6 mice and mouse ascites hepatoma 134-bearing C3H/He mice were immersed in a heated water bath. Rectal temperature was maintained for 30 min at 40 degrees C or 42 degrees C. After treatment, the incidence of lung metastasis was analyzed in LLC-inoculated mice, and ...
Background and Objectives: Enzymatic hydrolysis is an effective practical technology that recovers valuable proteins from far-less farmed fish without losing their nutritional characteristics. Enzymatic hydrolysis of protein sources such as aquatic animals is a type of protein recycling. In the present study, effects of temperature, time and concentration of papain enzyme on hydrolysis degree a...
acknowledgements i wish to express my gratitude to all those who have helped me in preparing this thesis. i would like to express my deep gratitude to my respected advisor dr. kourosh akef, whose advice and comments helped me in the early stages of the research and throughout the writing process. i would also like to express my gratitude to dr. hajar khanmohammad whose invaluable guidance he...
Mutations in the gene encoding topoisomerase I of Escherichia coli were tested for their effect on plasmid recombination. Recombination was decreased 1,000-fold at 30 and 37 degrees C and occurred at approximately wild-type frequencies at 42 degrees C. The suppression of topA mutations at 42 degrees C did not appear to be a result of increased topoisomerase I activity at 42 degrees C.
BACKGROUND Reported concentrations of amyloid beta (1-42) (A beta 42) and tau in cerebrospinal fluid (CSF) differ among reports. We investigated the effects of storage temperature, repeated freeze/thaw cycles, and centrifugation on the concentrations of A beta 42 and tau in CSF. METHODS Stability of samples stored at -80 degrees C was determined by use of an accelerated stability testing prot...
we have devided the thesis in to five chapters. the first recollects facts from purely algebraic theory of jordan algebras and also basic properties of jb and jb* - algebras which are needed in the sequel. in the second chapter we extend to jb* - algebras, a classical result due to cleveland [8]. this result shows shows the weakness of jb* - norm topology on a jb* - algebera. in chapter three, ...
