A method is presented that combines Carr-Purcell-Meiboom-Gill (CPMG) during acquisition with either selective or nonselective excitation to produce a considerable intensity enhancement and a simultaneous loss in chemical shift information. A range of parameters can theoretically be optimized very rapidly on the basis of the signal from the entire sample ...

Interleukin (IL)-6 is crucial for the induction of many murine models of autoimmunity including experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis. While IL-6-deficient mice (IL-6 KO) are resistant to EAE, we showed previously that in transgenic mice with astrocyte-targeted production of IL-6-restricted to the cerebellum (GFAP-IL6), EAE ...

Selenium is essential for the normal life processes, and all animals, including fish, need this inorganic element. In order to research the pathology of selenium deficiency in common carp, Cyprinus carpio L., 360 juvenile carp were allocated to three treatments. Each treatment containing 120 fish was randomly divided into four ...

Cathepsin K (CTSK) is secreted by osteoclasts to degrade collagen and other matrix proteins during bone resorption. Global deletion of Ctsk in mice decreases bone resorption, leading to osteopetrosis, but also increases the bone formation rate (BFR). To understand how Ctsk deletion increases the BFR, we generated osteoclast- and osteoblast-targeted ...

Epigallocatechin gallate (EGCG), a polyphenolic compound found in green tea, has gained considerable attention for its antitumor properties. Here we aimed to investigate the ...

Oxidative stress-induced neuronal cell death requires opening of the mitochondrial permeability transition pore. P53 mitochondrial translocation and association with Cyclophilin D (Cyp-D) is required for the pore opening. Here we tested this signaling axis in oxygen glucose deprivation (OGD)/re-oxygenation-induced in vitro neuronal death. Using mitochondrion immunoprecipitation, we found that p53 ...

Postmortem imaging is increasingly used in forensic practice in cases of natural deaths related to cardiovascular diseases, which represent the most common causes of death in developed countries. While radiological examination is generally considered to be a good complement for conventional autopsy, it was thought to have limited application in ...

Historically, chemists' exploration of chemical space has been exceptionally uneven and unsystematic.
