The effect of parathyroidectomy and/or vitamin D on the development of arterial and myocardial lesions was studied in rats with moderate uraemia. The activities of hexokinase and adenylate kinase in the aorta, myocardium and skeletal muscle were measured and the incidence of aortic calcification and
Sulfur mustard (SM; bis(2-chloroethyl)sulphide; HD) is a blister inducing agent causing DNA damage and subsequently, cell death, mostly by apoptosis in basal keratinocytes. Despite intensive investigations on the cellular mechanism, there are, as of now, no causal therapeutics to prevent or
We have evaluated the toxicity of four glyphosate (G)-based herbicides in Roundup formulations, from 10(5) times dilutions, on three different human cell types. This dilution level is far below agricultural recommendations and corresponds to low levels of residues in food or feed. The formulations
A nonmucoid clinical isolate of Pseudomonas aeruginosa, strain 808, elaborated ATP-dependent and ATP-independent types of cytotoxic factors in the growth medium. These cytotoxic factors, active against macrophages, were secreted during the exponential phase of growth in a complex medium.
Humans are exposed daily to a great number of xenobiotics and their metabolites present as pollutants. Bisphenol-A (BPA) is extensively used in a broad range of products including baby bottles, food-storage containers, medical equipment, and consumer electronics. Thus, BPA is the most common monomer
Calabadion 2 is a new drug-encapsulating agent. In this study, the authors aim to assess its utility as an agent to reverse general anesthesia with etomidate and ketamine and facilitate recovery.
To evaluate the effect of calabadion 2 on anesthesia recovery, the authors studied the response of rats
Caspase-independent cell death may have a critical role to play in the therapeutic destruction of tumours. Recently it has been suggested that one of the mechanisms by which rituximab, a therapeutic anti-CD20 antibody, kills B cells is caspase-independent. In this study we show that rituximab can
The accumulation of ATP by preparations of plasma membranes enriched particles (PMEP) isolated from rat hepatocytes, murine splenocytes and human T-lymphocytes has been investigated after the binding of human and murine tumour necrosis factors (TNF alpha) to their specific receptors. The TNF
Flavobacterium columnare, the causative agent of columnaris disease, is a serious bacterial disease responsible for causing devastating mortality rates in several species of freshwater fish, leading to severe economic losses in the aquaculture industry. Notwithstanding the enormous impacts this
Meat derives from a muscle that undergoes a great number of biochemical and physiological changes. The anoxic condition established from the moment of animal sacrifice forces muscle cells to a sort of reaction, resulting in methodical programmed cell death to avoid necrosis. The duality autophagy
Nervous necrosis virus (NNV), a piscine nodavirus, has caused serious viral nervous necrosis and viral encephalopathy and retinopathy in hatchery-reared larvae and juveniles of a wide range of marine teleost species worldwide in the last two decades. Although the mortality of NNV-infected larvae is
The toxicity of tributyltin chloride (TBT) involves Ca(2+) overload, cytoskeletal damage, and mitochondrial failure leading to cell death by apoptosis or necrosis. Here, we examined whether the intracellular ATP level modulates the mode of cell death after exposure to TBT. When Jurkat cells were
The precise coupling of spatially separated intracellular adenosine triphosphate (ATP)-producing and ATP-consuming, catalyzed by creatine kinase (CK), adenylate kinase (AK), and pyruvate kinase (PK), is a critical process in the bioenergetics of tissues with high energy demand, such as the branchial
Mitochondria play a central role in both apoptosis and necrosis through the opening of the mitochondrial permeability transition pore (MPTP). This is thought to be formed through a Ca(2+)-triggered conformational change of the adenine nucleotide translocase (ANT) bound to matrix cyclophilin-D and we
Skin affections after sulfur mustard (SM) exposure include erythema, blister formation and severe inflammation. An antidote or specific therapy does not exist. Anti-inflammatory compounds as well as substances counteracting SM-induced cell death are under investigation. In this study, we
