BACKGROUND & AIMS There have been many studies on plasma butyrylcholinesterase in liver dysfunction. However, no data is available about acetylcholinesterase in human cirrhosis, although profound changes have been described in cirrhotic rat models. METHODS Human serum and liver acetylcholinesterase and its molecular forms were determined enzymatically, after butyrylcholinesterase immunodeplet...
The short and long term effects of chromium toxicity on brain catecholamines and acetylcholinesterase levels were investigated. Rats were injected daily with varying amounts of chromium. The short term (2 h) administration of chromium (8 mmol/kg) reduced catecholamines level of cerebellum, mid-brain and brain-cortex by 22.8, 19.4 and 21.2% respectively. Acetylcholinesterase activity was also re...
BACKGROUND Tissues undergoing a chronic inflammatory process, such as the synovium in rheumatoid arthritis, are characterized by the infiltration of lymphocytes of different subsets and activation of monocyte/macrophages. Interleukin-1 (IL-1), a monocyte/ macrophage product that stimulates synovial fibroblasts to produce matrix metalloproteinases (MMPs), prostaglandins, and other cytokines, als...
Acetylcholinesterase is the enzyme that terminates neurotransmission by hydrolyzing the acetylcholine released by the motoneurons at the neuromuscular junctions. Although acetylcholinesterase has been studied for almost a century, the underlying relationship between exercise-induced fatigue and acetylcholinesterase activity at the synaptic cleft is not clear. The purpose of this study was to as...
The ability of rats or mice to withstand the consequences of injury to myelinated axons in the CNS was previously shown to depend on the ability to manifest a T cell-mediated protective immune response, which is amenable to boosting by myelin-specific T cells. Here we show that this ability, assessed by retinal ganglion cell survival after optic nerve injury or locomotor activity after spinal c...
Novel therapies for lung cancer are being explored nowadays with local therapies being the tip of the arrow. Intratumoral chemotherapy administration and local microwave ablation have been investigated in several studies. It has been previously proposed that lipiodol has the ability to modify the microenvironment matrix. In our current study we investigated this theory in BALBC mice. In total 1...
We have recently reported that acetylcholinesterase expression was induced during apoptosis in various cell types. In the current study we provide evidence to suggest that the induction of acetylcholinesterase expression during apoptosis is regulated by the mobilization of intracellular Ca(2+). During apoptosis, treatment of HeLa and MDA-MB-435s cells with the calcium ionophore A23187 resulted ...
PURPOSE Optical coherence tomography angiography (OCT-A) allows noninvasive visualization of retinal vessels in vivo. OCT-A was used to characterize the vascular network of the mouse retina and was compared with fluorescein angiography (FA) and histology. METHODS In the present study, OCT-A based on a Heidelberg Engineering Spectralis system was used to investigate the vascular network in mic...
Lung cancer remains the leading cause of death in cancer patients. Severe treatment side effects and late stage of disease at diagnosis continue to be an issue. We investigated whether local treatment using 2-diethylaminoethyl-dextran methyl methacrylate copolymer with p53 (DDMC-p53) with or without cisplatin and/or microwave ablation enhances disease control in BALBC mice. We used a Lewis lung...
patients with alzheimer's disease have cognitive deficits, impaired long-term potentiation and learning and memory. a progressive reduction in cholinergic neurons in some areas of the brain such as cortex and hippocampus is related to the deficits in memory and cognitive function in alzheimer’s disease (ad). in the current project a new series of phthalimide derivatives were synthesized. p...
