BACKGROUND Panax notoginseng saponins (PNS) extracted from the roots of panax notoginseng are free radical-scavenger, with an antioxidant property, capable of inhibiting expression of adhesion molecules and chemokines. This study was designed to test the effects of PNS administration in apolipoprotein (apo)-E-deficient mice on the activation of JNK, p38(MAPK), ERK1/2 and NF-κB, and the expressi...

BACKGROUND ACCEPt, a large cluster randomized control trial, aims to determine if annual testing for 16 to 29 year olds in general practice can reduce chlamydia prevalence. ACCEPt is the first trial investigating the potential role of practice nurses (PN) in chlamydia testing. To inform the design of the ACCEPt intervention, we aimed to determine the chlamydia knowledge, attitudes, and testing ...

Inhibiting oxidative damage in early stage of Alzheimer's disease (AD) is considered as a strategy for AD treatment. Our previous study has shown that Panax notoginseng saponins (PNS) have an antiaging action by increasing the levels of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-PX) in the serum of aged rats. In this study, we aimed to investigate the effects of...

An important role for the neural extracellular matrix in modulating cortical activity-dependent synaptic plasticity has been established by a number of recent studies. However, identification of the critical molecular components of the neural matrix that mediate these processes is far from complete. Of particular interest is the perineuronal net (PN), an extracellular matrix component found sur...

BACKGROUND/AIM Neuropathy is the most common neurologic complication of HIV but is widely under-diagnosed in resource-constrained settings. We aimed to identify tools that accurately distinguish individuals with moderate/severe peripheral neuropathy and can be administered by non-physician healthcare workers (HCW) in resource-constrained settings. METHODS We enrolled a convenience sample of 3...

BACKGROUND Support in primary care can assist smokers to quit successfully, but there are barriers to general practitioners (GPs) providing this support routinely. Practice nurses (PNs) may be able to effectively take on this role. OBJECTIVES The aim of this study was to perform a process evaluation of a PN-led smoking cessation intervention being tested in a randomized controlled trial in Au...

Brain extracellular matrix (ECM) is organized in specific patterns assumed to mirror local features of neuronal activity and synaptic plasticity. Aggrecan-based perineuronal nets (PNs) and brevican-based perisynaptic axonal coats (ACs) form major structural phenotypes of ECM contributing to the laminar characteristics of cortical areas. In Alzheimer's disease (AD), the deposition of amyloid pro...

Paraneoplastic neurological syndromes (PNS) are disorders of the nervous system that are associated with remote effects of malignancy. PNS are considered to have an autoimmune pathology. It has been suggested that immune antitumor responses are the origin of improved outcome in PNS. We describe cell-mediated immune responses in PNS and their potential contributions to antitumor reactions. Exper...

The goal of this experiment was to investigate the protective effect and the molecular mechanism of Panax Notoginseng Saponins (PNS) on cisplatin-induced nephrotoxicity through mitochondrial pathway of apoptosis. The rats underwent intraperitoneal injection with a single dose of cisplatin, a subset of rats were also intraperitoneally injected with 31.35 mg/kg PNS once a day for 8 days. At day 1...
