Manifestations of local tissue damage, such as hemorrhage and myonecrosis, are among the most dramatic effects of envenomation by viperid snakes. Snake venom metalloproteinases (SVMPs) of the P-III class are main players of the hemorrhagic effect due to their activities in promoting blood vessel
The aim of the current article is to overview the recent developments in the field of hemorrhagic shock research, as it relates to the roles of nitric oxide (NO) in the pathogenesis of this condition. The first part of the review focuses on the roles of peroxynitrite, a reactive oxidant produced
Thrombogenic responses are sometimes seen after a large hemorrhage, but the precise mechanisms whereby this phenomenon occurs still remain unknown. We recently showed that plasminogen activator inhibitor-1 rises after a 20-ml/kg hemorrhage in rats and suggested that this change may be one of the
A major complication of aneurysmal subarachnoid hemorrhage (SAH) is symptomatic vasospasm, a complex syndrome consisting of neurological deterioration and exclusion of other sources of ischemia. Approximately 30% of SAH patients are affected. Although symptomatic vasospasm is associated with high
Background Matrix metalloproteinases (MMPs) play a key role in the degradation of basement membrane and extracellular matrix in tissue remodeling, and are involved in pathogenesis of intracranial hemorrhage (ICH). Despite replacement therapy, ICH is by far the main cause of bleeding-related death
Changes in gene expression are commonly assessed relative to the expression of housekeeping genes, which are assumed to remain unchanged. We tested this assumption in cerebral arteries obtained from dogs 4 and 7 days after subarachnoid hemorrhage (SAH) had been created using the double hemorrhage
Glutaric aciduria type I is an inherited defect in L-lysine, L-hydroxylysine and L-tryptophan degradation caused by deficiency of glutaryl-CoA dehydrogenase (GCDH). The majority of untreated patients presents with accumulation of neurotoxic metabolites - glutaric acid (GA) and 3-hydroxyglutaric acid
Ibuprofen is a commonly used non-steroidal anti-inflammatory drug. Gastrointestinal adverse drug reactions from ibuprofen usage include gastric mucosal ulcers and bleeding. The mechanism by which ibuprofen induces gastric mucosal damage is not clear. The present study is an attempt to examine the
OBJECTIVE
To observe the changes of relative expression of myocardial various RNAs in rats died of different causes and their relationship with PMI.
METHODS
The rat models were established in which the rats were sacrificed by broken neck, asphyxia, and hemorrhagic shock. Total RNAs were extracted
Peroxynitrite is a reactive oxidant produced from nitric oxide (NO) and superoxide, which reacts with proteins, lipids, and DNA under conditions of inflammation and shock. Here we overview the role of peroxynitrite in circulatory shock and inflammation. Immunohistochemical and biochemical evidence
BACKGROUND
Platelets (PLTs) contain mRNA and synthesize proteins in response to activation. Most guidelines for PLT concentrates (PCs) recommend ambient temperature for storage but the impact of the storage temperature on PLT mRNA content has not yet been investigated.
METHODS
Ten leukoreduced
Hypoxia is the lack of sufficient oxygenation of tissue, imposing severe stress upon cells. It is a major feature of many pathological conditions such as stroke, traumatic brain injury, cerebral hemorrhage, perinatal asphyxia and can lead to cell death due to energy depletion and increased free
Peroxynitrite is a reactive oxidant produced from nitric oxide and superoxide, which reacts with proteins, lipids, and DNA, and promotes cytotoxic and proinflammatory responses. Here, we overview the role of peroxynitrite in various forms of circulatory shock. Immunohistochemical and biochemical
Probiotics are known to have an inhibitory effect against the growth of various foodborne pathogens, however, the specific role of probiotics in Shiga-toxin-producing Escherichia coli (STEC) virulence gene expression has not been well defined. Shiga toxins are members of a family of highly potent
The aim of the study was to determine the source of vascular endothelial growth factor (VEGF) in hematoma fluid of patients suffering from chronic subdural hematoma (CSH) and to identify the level of gene expression of the pro-angiogenic factors angiopoietin 1 (ANG-1) and ANG-2 in hematoma
