A combined therapy of sulindac sulfide and tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a promising strategy for the treatment of cancer. Sulindac sulfide had been shown to induce the expression of death receptor 5 (DR5), a receptor for TRAIL, and sensitize cancer cells to TRAIL-induced apoptosis; however, the molecular mechanism underlying the upregulation of DR5 has not ...
New method for quantification of gasotransmitter hydrogen sulfide in biological matrices by LC-MS/MS
Hydrogen sulfide exists widely in mammalian tissues and plays a vital role in physiological and pathophysiological processes. However, striking differences with orders of magnitude were observed for the detected hydrogen sulfide concentrations in biological matrices among different measurements in literature, which lead to the uncertainty for examination the biological relevance of hydrogen sul...
Investigation of various species lichen as biomonitors air pollutants deposition and evaluation element pollution were aimed. Maximum accumulation was 43.9±2.1 mg/kg in X. somloensis. Strontium quite high. Percentages strontium for L.pulmonaria, C.furcata, U.longissima, X.somloensis, F.caperata between 58% 78% indicating the efficient strontium. Lichens also accumulated strategically important ...
P-101: Effects of Ethanol and Strontium on Growth and Development of Two-Cell Arrested Mouse Embryos
Background: Arresting in a certain step of development like two-cell stage could be one of the reasons of infertility. The aim of this study is evaluating the effects of ethanol and strontium on growth and development of two-cell arrested mouse embryos. Materials and Methods: The females were coupled with male following superovulation. Positive vaginal plug mice were killed 48 hours after hCG i...
The development of new analytical techniques enabled the precise determination expanded set stable isotopes and provided insight into existing geological issues. This review outlines recent studies non-traditional isotope signatures in matrices, summarizing one place data for Ca, Mg, Sr, Li, Ni, Cr, Cu their application interpretation environmental processes. Although some them, such as ?44Ca ?...
from Rasmussen, C.E. 1988. The use of strontium as an indicator of anthropogenically altered environmental parameters. "Proceedings of the Sixth International Coral Reef Symposium," Townsville, Australia, 8th-12th August 1988. pp. 325-330. ISBN 0-7316-5607-5: The use of strontium levels precipitated into coral skeletal material has long been recognised as an indicator of oceanic temperature at ...
We investigated aerobic and anaerobic thiotrophic metabolism by the gutless clam Solemya reidi and its intracellular symbiotic bacteria. Mean environmental sulfide concentrations in porewater next to animals varied from a high of 888 μM to a low of 17 μM in different sediment samples, while mean thiosulfate concentrations were very low (1-13 μM). The blood of freshly collected clams contained u...
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
Polymorphonuclear leukocytes (PMN) isolated from human blood were exposed to various levels of hydrogen sulfide. The effect on respiratory burst, myeloperoxidase activity, and capacity to phagocytose and kill bacteria were studied. A 1-h exposure of the PMN to 1 mM sulfide did not decrease their myeloperoxidase activity or their capacity to initiate a respiratory burst. Actually the products of...
Hydrogen sulfide is gaining acceptance as an endogenously produced modulator of tissue function. The present paradigm of H(2)S (diprotonated, gaseous form of hydrogen sulfide) as a tissue messenger consists of H(2)S being released from the desulfhydration of l-cysteine at a rate sufficient to maintain whole tissue hydrogen sulfide concentrations of 30 microM to >100 microM, and these tissue con...
