Purpose: It was aimed to evaluate the effect of hydrogen peroxide (H2O2), mitochondria isolated from human breast cancer cells (MCF-7) and mesenchymal stem (IMSCs) on MCF-7 cell proliferation in this study.
 Materials Methods: Mitochondria IMSCs were according protocols specified kit protein amount measured by bicinchoninic acid method (BCA). H2O2 doses (0-1000 µM), obtained transferred vi...

The direct and indirect plaque technique for the detection of antibody-forming cells against sheep erythrocytes was utilized for the investigation of a number of biological parameters of the primary and secondary immune response on a cellular level. The sequential pattern of 19S followed by 7S antibody formation was elicited in the primary response after a latent period of at least 1-2 days and...

Cycloabiesesquine A, representing a unique carbon skeleton among the sesquiterpenoids, was isolated from Abies delavayi and by extensive spectroscopic and computational methods, its structure was elucidated as (7S,8R,12R)-4,8-dihydroxy-1,3,5,10-tetraen-8,12-cyclobisabolan-9-one.

Guinea pig 7Sgamma(2) antibodies were demonstrated to fix complement in the presence of antigen and to sensitize antigen-coated, tanned erythrocytes for lysis in the presence of complement; guinea pig 7Sgamma(1) antibodies did not participate in these reactions. Gamma-2 antibodies were more efficient in provoking hemorrhagic necrosis in reverse passive Arthus reactions than equal amounts of non...

We report a measurement of the radium ion's $7p$ ${}^{2}P_{3/2}$ state lifetime, $\tau=4.78(3)$ ns. The measured lifetime is in good agreement with theoretical calculations, and will enable determination differential scalar polarizability narrow linewidth $7s$ ${}^{2}S_{1/2}\rightarrow$ $6d$ ${}^{2}D_{5/2}$ optical clock transition.

A recessive temperature sensitive mutant has been isolated that is defective in ribosomal RNA processing. By Northern analysis, this mutant was found to accumulate three novel rRNA species: 23S', 18S' and 7S', each of which contains sequences from the spacer region between 25S and 18S rRNA. 35S pre-rRNA accumulates, while the level of the 20S and 27S rRNA processing intermediates is depressed. ...
