Objectives: To determine the risk perceptions of a series of medical practices in non-expert (undergraduates) and expert (nurses) samples.

Methods: Four hundred and forty-seven nurses and 246 undergraduate students participated in this study. They all answered questionnaires about the risk dimensions and acceptance for medical practices.

Plasma Amino Acid Profile in Patients with Aortic Dissection.

Aortic dissection (AD), a severe cardiovascular disease with the characteristics of high mortality, is lack of specific clinical biomarkers. In order to facilitate the diagnosis of AD, we investigated plasma amino acid profile through metabolomics approach. Total 33 human subjects were enrolled in the study: 11 coronary heart disease (CHD) patients without aortic lesion and 11 acute AD and 11 chronic AD.

Opposing roles for SNAP23 in secretion in exocrine and endocrine pancreatic cells.

The membrane fusion of secretory granules with plasma membranes is crucial for the exocytosis of hormones and enzymes. Secretion disorders can cause various diseases such as diabetes or pancreatitis. Synaptosomal-associated protein 23 (SNAP23), a soluble N-ethyl-maleimide sensitive fusion protein attachment protein receptor (SNARE) molecule, is essential for secretory granule fusion in several cell lines.

Amelioration of salvianolic acid C on aortic structure in apolipoprotein E-deficient mice treated with angiotension II.

Aims: Aortic aneurysm is a disastrous vascular disease with high morbidity and mortality. Matrix metalloproteinases (MMPs), especially MMP-9, is implicated in the development of aortic aneurysm, but the effective MMP inhibitors are far from development. To develop new candidate compound for aortic aneurysm therapy, we evaluated the effects of salvianolic acid C (SalC) against the formation of aortic aneurysm.

Extraction of items identifying hiesho (cold disorder) and their utility in young males and females.

Objective: Hie (cold sensation) is one of the most common health complaints in Japan. Those who suffer from severe hie are considered as having hiesho (cold disorder). However, exact hiesho symptoms have not been defined clearly and the decision as to whether a person suffers from hiesho is subjective and based on self-awareness.

Downregulation of TRAP1 sensitizes glioblastoma cells to temozolomide chemotherapy through regulating metabolic reprogramming.

Cancer cells preferentially use aerobic glycolysis to support growth, a metabolic alteration commonly referred to as the 'Warburg effect.' Here, we show that the tumor necrosis factor receptor-associated protein 1 (TRAP1) is crucial for the Warburg effect in human glioblastoma multiforme (GBM). In contrast to normal brain, GBMs show increased TRAP1 expression.

The Safety Evaluation of Salvianolic Acid B and Ginsenoside Rg1 Combination on Mice.

Our previous study indicated that the combination of salvianolic acid B (SalB) and ginsenoside Rg1 (Rg1), the main components of Salvia miltiorrhizae and Panax notoginseng, improves myocardium structure and ventricular function in rats with ischemia/reperfusion injury. The present study aimed to determine the safety of the combined SalB and Rg1 (SalB-Rg1) in mice. The safety of SalB-Rg1 was evaluated through acute toxicity and repeated-dose toxicity.

Combined Salvianolic Acid B and Ginsenoside Rg1 Exerts Cardioprotection against Ischemia/Reperfusion Injury in Rats.

Lack of pharmacological strategies in clinics restricts the patient prognosis with myocardial ischemia/reperfusion (I/R) injury. The aim of this study was to evaluate the cardioprotection of combined salvianolic acid B (SalB) and ginsenoside Rg1 (Rg1) against myocardial I/R injury and further investigate the underlying mechanism. I/R injury was induced by coronary artery ligation for Wistar male rats and hypoxia/reoxygenation injury was induced on H9c2 cells.

Slow Progression of Cognitive Dysfunction of Alzheimer's Disease in Sexagenarian Women with Schizophrenia.

Although both schizophrenia (SCZ) and Alzheimer's disease (AD) are among the most common psychiatric diseases, the interaction of these two is not well-understood. We investigated three women with SCZ who developed AD in their 60s. The patients presented with cognitive dysfunction such as loss of recent memory, which was confirmed by both clinical observations and neuropsychological tests.

Selective elimination of isolectin B4-binding trigeminal neurons enhanced formalin-induced nocifensive behavior in the upper lip of rats and c-Fos expression in the trigeminal subnucleus caudalis.

The functional significance of non-peptidergic C-fibers in orofacial pain processing is largely unknown. The present study examined the effects of the selective elimination of isolectin B4 (IB4)-binding (IB4(+)) neurons on formalin-induced face rubbing behavior (FRB) in the upper lip of rats and c-Fos-immunoreactive (c-Fos-IR) cells in the trigeminal subnucleus caudalis (Vc). IB4 conjugated to neurotoxin, saporin (IB4-Sap), blank-saporin (Bl-Sap), or saline (Sal) was injected into the cisterna magna.

Salvianolic acid A inhibits endothelial dysfunction and vascular remodeling in spontaneously hypertensive rats.

Aims: Despite the numerous pharmacological agents available for hypertension therapy, hypertension-related microvascular remodeling is not resolved, eventually leading to end-organ damage. The aim of the present study was to investigate the protection of salvianolic acid A (SalA) against microvascular remodeling in vitro and in vivo.

Main Methods: Spontaneously hypertensive rats (SHRs) were administered 2.

Functional redundancy of protein kinase D1 and protein kinase D2 in neuronal polarity.

Mammalian protein kinase D (PKD) isoforms have been proposed to regulate diverse biological processes, including the establishment and maintenance of neuronal polarity. To investigate the function of PKD in neuronal polarization in vivo, we generated PKD knockout (KO) mice. Here, we show that the brain, particularly the hippocampus, of both PKD1 KO and PKD2 KO mice was similar to that of control animals.

Ginsenoside Rg1 and Rb1, in combination with salvianolic acid B, play different roles in myocardial infarction in rats.

Background: The herb pair of Salvia miltiorrhiza and Panax notoginseng has widely been used for improving coronary and cerebral circulation in China. However, the exact contribution of the major active components of S. miltiorrhiza and P.

The effect of electroacupuncture on tendon repair in a rat Achilles tendon rupture model.

Objective: To examine the effect of electroacupuncture (EA) on early post-rupture tendon repair in a rat model of Achilles tendon rupture using histological and mechanical evaluation.

Methods: An Achilles tendon rupture model was prepared in 90 Wistar rats, which were randomly assigned to EA, manual acupuncture or control groups. Rats in the EA group received EA (pulse width 5 ms; stimulation frequency 50 Hz; stimulation strength 20 μA; stimulation time 20 min) daily from 1 day following model preparation until the day of assessment (either 7 or 10 days after model preparation), when the region of interest was sampled to assess tendon repair using in vitro methods.

Jaw movement-related primary somatosensory cortical area in the rat.

It has anatomically been revealed that the rostral part of the rat primary somatosensory cortex (S1) directly projects to the dorsal part of the trigeminal oral subnucleus (dorVo) and the dorsal part of juxtatrigeminal region (dorVjuxt), and that the dorVo and dorVjuxt contain premotoneurons projecting directly to the jaw-opening or jaw-closing motoneurons in the trigeminal motor nucleus (Vmo). However, little is known about how the rostral S1 regulates jaw movements in relation to its corticofugal projections. To address this issue, we performed intracortical microstimulation of the rat rostral S1 by monitoring jaw movements and electromyographic (EMG) activities.

[Depression in dementia with Lewy bodies].

Depression is a risk factor for dementia in general, including Alzheimer's disease (AD), its premorbid signs are commonly observed, and the morbidity of depression is higher in dementia patients. Dementia with Lewy bodies (DLB) is considered to have an even higher depression prevalence and premorbid depression rate than other dementias such as AD. This led to depression being listed as a supportive feature in the 2005 criteria for the clinical diagnosis of DLB.

Preventive effect of nucleoprotein on hindlimb unloading-induced capillary regression in rat soleus muscle.

We investigated the preventive effects of nucleoprotein on capillary regression and mitochondrial dysfunction induced by unloading in the soleus muscle of rats. Nucleoprotein is a supplement made from soft roe of salmon, and its major components are nucleotides and protamine. Adult male Sprague-Dawley rats were divided randomly into control, hindlimb unloading (HU), and hindlimb unloading plus nucleoprotein administration (HU+ NP) groups.

Validity of the Water Hammer Formula for Determining Regional Aortic Pulse Wave Velocity: Comparison of One-Point and Two-Point (Foot-to-Foot) Measurements Using a Multisensor Catheter in Human.

Background: Lack of high-fidelity simultaneous measurements of pressure and flow velocity in the aorta has impeded the direct validation of the water-hammer formula for estimating regional aortic pulse wave velocity (AO-PWV1) and has restricted the study of the change of beat-to-beat AO-PWV1 under varying physiological conditions in man.

Methods: Aortic pulse wave velocity was derived using two methods in 15 normotensive subjects: 1) the conventional two-point (foot-to-foot) method (AO-PWV2) and 2) a one-point method (AO-PWV1) in which the pressure velocity-loop (PV-loop) was analyzed based on the water hammer formula using simultaneous measurements of flow velocity (Vm) and pressure (Pm) at the same site in the proximal aorta using a multisensor catheter. AO-PWV1 was calculated from the slope of the linear regression line between Pm and Vm where wave reflection (Pb) was at a minimum in early systole in the PV-loop using the water hammer formula, PWV1 = (Pm/Vm)/ρ, where ρ is the blood density.
