Cyclooxygenase inhibition in ischemic brain injury [PDF]

Current Pharmaceutical Design 2008; 14(14):1401-1418, 2008
Neuroinflammation is one of the key pathological events involved in the progression of brain damage caused by cerebral ischemia. Metabolism of arachidonic acid through cyclooxygenase (COX) enzymes is known to be actively involved in the neuroinflammatory events leading to neuronal death after ischemia.

Carbon Doping of MgB2 by Toluene and Malic-Acid-in-Toluene [PDF]

, 2010
The decomposition of malic acid in the presence of Mg and B was studied using Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA) which revealed that malic acid reacted with Mg but not B. Also, the addition of toluene to dissolve malic acid followed by subsequent drying resulted in no reaction with Mg, indicating that the malic

Characterization of the pattern of development of key compounds contributing to aroma quality of chicken meat and their metabolic markers

Animal Research and One Health, EarlyView.
The graphical abstract shows the principal results of this study. Eight major aroma‐contributing compounds (nonanal, octanal, dimethyl tetrasulfide, hexanal, 1‐octen‐3‐ol, (E)‐2‐nonenal, heptanal, and (E,E)‐2,4‐decadienal) were identified by electronic nose and GC‐O‐MS analysis, and their content increased with age.

Dihydroartemisinin inhibits melanoma migration and metastasis by affecting angiogenesis

Phytotherapy Research, EarlyView., 2023
Abstract Tumor angiogenesis is critical for tumor metastasis by providing oxygen, nutrients, and metastatic pathways. As a potential anti‐angiogenic agent, Dihydroartemisinin (DHA) can effectively inhibit tumor metastasis. However, the mechanism how it regulates angiogenesis to affect tumor metastasis has not been fully clarified.

Metabolism of n-3 polyunsaturated fatty acids and modification of phospholipids in cultured rabbit aortic smooth muscle cells.

Journal of Lipid Research, 1985
The metabolism of the linolenic acid family (n-3) of fatty acids, e.g., linolenic, eicosapentaenoic, and docosahexaenoic acids, in cultured smooth muscle cells from rabbit aorta was compared to the metabolism of linoleic and arachidonic acids.

Delayed treatment with nimesulide reduces measures of oxidative stress following global ischemic brain injury in gerbils [PDF]

Neuroscience Research 47(2): 245-253 (2003), 2007
Metabolism of arachidonic acid by cyclooxygenase is one of the primary sources of reactive oxygen species in the ischemic brain. Neuronal overexpression of cyclooxygenase-2 has recently been shown to contribute to neurodegeneration following ischemic injury.

A search for mid-IR bands of amino acids in the Perseus Molecular Cloud [PDF]

arXiv, 2021
Amino acids are building-blocks of proteins, basic constituents of all organisms and essential to life on Earth. They are present in carbonaceous chondrite meteorites and comets, but their origin is still unknown. Formation of amino acids in the interstellar medium is posible via specific gas-phase reactions in dark clouds, however sensitive ...

Fresh insights into the light‐induced pineal gland circadian rhythm transmission mechanism derived from mRNA and miRNA profiling

Animal Research and One Health, EarlyView.
Mechanisms of light in regulating the chick pineal clock. Abstract The circadian clock significantly impacts animal health and productivity, with light playing a crucial role in regulating circadian rhythms. However, the mechanisms behind light‐induced circadian transmission remain unclear, particularly in light‐sensitive avian species.

Arachidonic Acid Stress Impacts Pneumococcal Fatty Acid Homeostasis

Frontiers in Microbiology, 2018
Free fatty acids hold dual roles during infection, serving to modulate the host immune response while also functioning directly as antimicrobials. Of particular importance are the long chain polyunsaturated fatty acids, which are not commonly found in ...

Acid zeta function and ajoint acid zeta function [PDF]

arXiv, 2010
In this paper we set up the theory of acid zeta function and ajoint acid zeta function, based on the theory, we point out a reason to doubt the truth of the Riemann hypothesis and also as a consequence, we give out some new RH equivalences.
