Panax notoginseng, a traditional Chinese herbal medicine, has been used for the treatment of cardiovascular diseases. The main bioactive components of this species are Panax notoginseng saponins (PNS). The present study aimed to investigate the effects of PNS and five of its main components (ginsenosides Rg1, Re, Rb1 and Rd, and notoginsenoside R1) on rat aorta rings pre-contracted with norepin...

BACKGROUND Partner notification services (PNS) are recommended by the Centers for Disease Control and Prevention as a public health intervention for addressing the spread of HIV and other sexually transmitted diseases (STDs). Barriers and facilitators to the partner notification process from a public health perspective have not been well described. METHODS In 2015, a coalition of New England ...

Candidate propriospinal neurons (PNs) that mediate disynaptic pyramidal excitation to forelimb motoneurons were studied in the C3-C4 segments in anesthetized macaque monkeys (n = 10). A total of 177 neurons were recorded (145 extracellularly, 48 intracellularly, and 16 both) in laminae VI-VII. Among these, 86 neurons (73 extracellularly, 14 intracellularly and 1 both) were antidromically activa...

Most computer programs for board games successfully employ αβ search. For some games, however, αβ search displays a weakness in the endgame that can currently neither be overcome by endgame databases nor by other αβ extensions. To remedy the deficit, mate searches may be applied. One such alternative to αβ search is Proof-Number Search (PNS). PNS enjoys popularity as a powerful method for solvi...

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...
