Reactive oxygen species (ROS) are products of normal metabolic activities and are thought to be the cause of many diseases. A selenium-containing single-chain abzyme 2F3 (Se-2F3-scFv) that imitates glutathione peroxidase has been produced which has the capacity to remove ROS. To evaluate the antioxidant ability of Se-2F3-scFv, we con-structeda ferrous sulfate/ascorbate (Vc/Fe 2+ )-inducedmito-chondrial damage model system and investigated the capacity of Se-2F3-scFv to protect mitochondria from oxi-dative damage.

a-Crystallin, a molecular chaperone and lens structural protein protects soluble enzymes against heat-induced aggregation and inactivation by a variety of molecules. In this study we investigated the chaperone function ofa-crys-tallininamorephysiological systeminwhicha-crystallinwas incorporated into red cell
ghosts. Its ability to protect the intrinsic membrane protein Na/K-ATPase from external stresses was studied. Red cell ghosts were created by lysing the red cells and removing cytoplasmic contents by size-exclusion chromatography. ...

The bacterial Lsm protein, host factor I (Hfq), is an RNA chaperone involved in many types of RNA transactions such as replication and stabil-ity, control of small RNA activity and polyadenylation. In this latter case, Hfq stimulates poly(A) synthesis and binds poly(A) tails that it protects from exonucleolytic degradation. We show here, that there is a correlation between Hfq binding to the 3¢ end of an RNA molecule and its ability to stimulate RNA elongation catalyzed by poly(A)polymerase I.

Reactive oxygen species contribute to the development of various human diseases. Ischemia is characterized by both significant oxidative stress and characteristic changes in the antioxidant defense mechanism. Heat shock protein 27 (HSP27) has a potent ability to increase cell survival in response to oxidative stress. In the present study, we have investigated the protective effects of PEP-1–HSP27 against cell death and ischemic insults.

Fatty acids can stimulate the secretory activity of insulin-producing beta-cells. At elevated concentrations, they can also be toxic to isolated beta-cells. This toxicity varies inversely with the cellular ability to accumulate neutral lipids in the cytoplasm. To further examine whether cytoprotection can be achieved by decreasing cytoplasmic levels of free acyl moieties, we investigated whether palmitate toxicity is also lowered by stimulating its b-oxidation.

Natural polyamines (putrescine, spermidine, and spermine) self-assemble in a simulated physiological environment (50 mmsodium phosphate buffer, pH 7.2), generating in vitro nuclear aggregates of polyamines (ivNAPs). These supramolecular compounds are similar in structure and molecular mass to naturally occurring cellular nuclear aggregates of polyamines, and they share the ability of NAPs to interact with and protect the genomic DNA against nuclease degradation.

Hepatic stimulator substance (HSS) has been shown to protect liver cells from various toxins. However, the mechanism by which HSS protects hepatocytes remains unclear. In this study, we established BEL-7402 cells that stably express HSS and analyzed the protective ability of HSS on cells through mitochondrial permeability (MP).

The US Environment Protection Agency defines arsenic as a persistent, bio-accumulative, and toxic chemical having the ability to accumulate in the air, soil, and water. In 1961, the pollution of arsenic was first discovered in Taiwan, and later in Belgium, Netherland, Germany, Italy, Hungary, Portugal, The Philippines, Ghana, USA, Chile, Mexico, Argentina, and Thailand. In 1992, the toxicity of arsenic was found as a disaster in West Bengal, India.

Understanding human anatomy will help you achieve greater expressive ability in figure drawing. By understanding the many different aspects of the human form, you can better grasp how the figure works as a whole. For example, if you feel along the bone on the lower part of your jaw, you will notice that there is a small indentation about halfway between the chin and the back of the jaw. This indentation is to allow a blood vessel to pass under the jaw. The indentation helps to protect the vessel. The significance of this little indentation is that it affects the...
