OBJECTIVE
Compaction of extracellular matrix (ECM) lattices by cultured fibroblasts was accelerated by cerebrospinal fluid (CSF) from patients with subarachnoid hemorrhage (SAH). The rate of acceleration was significantly related to the clinical grade of vasospasm. However, the mechanism remains
BACKGROUND
Smoking is one of the most important risk factors for cerebral circulatory disorders. The purpose of this study was to investigate the influence of experimental subarachnoid hemorrhage (SAH) on nicotine-induced contraction (arachidonic acid metabolites) in the basilar arteries of
Vitamin C deficient pigs, when fed a diet lacking L-ascorbic acid (AscA), manifest deformity of the legs, multiple fractures, osteoporosis, growth retardation and haemorrhagic tendencies. This trait was shown by others to be controlled by a single autosomal recessive allele designated as od
OBJECTIVE
Cyclophosphamide (Sigma) is associated with urological complications, including irritative voiding symptoms and hemorrhagic cystitis. Evidence suggests that tumor necrosis factor-alpha (R&D Systems), interleukin-1beta and cyclooxygenase-2 are directly involved in the pathogenesis of
Intravenous conjugated estrogens reduce the prolonged bleeding time in uremic patients and in a rat model of uremia. However, estrogens have major side effects related to their hormonal activity. We investigated whether a beta-resorcylic acid lactone, zeranol (a compound with close spatial
The left middle cerebral artery occlusion (MCAO) model was made by inserting the nylon thread plug into the internal carotid artery. The behavioral score, cerebral infarction area, brain water content, ethidium bromide (EB) spillover, coagulation four indices, occludin and MMP-9 expression in brain
Vibrio anguillarum, which causes terminal hemorrhagic septicemia in fish, was previously shown to possess a LuxRI-type quorum-sensing system (vanRI) and to produce N-(3-oxodecanoyl)homoserine lactone (3-oxo-C10-HSL). However, a vanI null mutant still activated N-acylhomoserine lactone (AHL)
A promising therapeutic approach to reduce pathological inflammation is to inhibit the increased production of pro-inflammatory cytokines (e.g., TNF-alpha, IL-6). In this study, we investigated the anti-inflammatory potential of 7-hydroxyfrullanolide (7HF). 7HF is an orally bioavailable, small
Neuroinflammation and oxidative stress are key contributors to intracranial hemorrhage (ICH)-induced brain injury. Parthenolide (PN) is a sesquiterpene lactone that has been observed to have antioxidative, anti-inflammatory, and neuroprotective potentials. However, the role of PN in ICH remains
Certain gram-negative pathogens are known to control virulence gene expression through cell-cell communication via small diffusible signal molecules termed autoinducers. This intercellular signal transduction mechanism termed quorum sensing depends on the interaction of an N-acylhomoserine lactone
Platelets play a crucial role in the development and progression of atherosclerosis-thrombosis and, therefore, antiplatelet drugs are widely used in the treatment of coronary artery disease. Moreover, advances in understanding the biological functions of natural plant products can provide new
Enterohemorrhagic Escherichia coli (EHEC) causes hemorrhagic colitis and life-threatening complications. The main reservoirs for EHEC are healthy ruminants. We reported that SdiA senses acyl homoserine lactones (AHLs) in the bovine rumen to activate expression of the glutamate acid resistance (gad)
OBJECTIVE
We conducted a phase I trial of the injectable formulation of topotecan given orally once daily for 5 days for 2 consecutive weeks (qd x 5 x 2) in pediatric patients with refractory solid tumors.
METHODS
Cohorts of two to six patients received oral topotecan at 0.8, 1.1, 1.4, 1.8, and 2.3
P2Y12 antagonists are widely used as antiplatelet agents for the prevention and treatment of arterial thrombosis. Based on the scaffold of a known P2Y12 antagonist AZD1283, a series of novel bicyclic pyridine derivatives were designed and synthesized. The cyclization of the
Refrigerated storage is widely applied in order to maintain peach quality but it can also induce chilling injuries (CIs) such as flesh browning and bleeding, and mealiness. Peach fruit from three cultivars ('Red Haven', RH, 'Regina di Londa', RL, and 'Flaminia', FL) were stored for 4 weeks under low
