Neural Regeneration Research 2010年第2期5卷 156-160页

作者： Yueloong hsin cheryl c h Yang terry B J Kuo Tomor harnod School of Medicine Tzu Chi University Department of Neurology Buddhist Tzu Chi General Hospital Institute of Brain Science National Yang Ming University Department of Neurosurgery Buddhist Tzu Chi General Hospital

BAcKGROUND： Dysfunctional autonomic cardiac regulation is thought to be associated with high mortality in epileptic patients. OBJEcTIVE： To explore changes in sympathetic and parasympathetic activities in epileptic patients with repetitive generalized tonic-clonic seizures by observing interictal heart rate. DESIGN, TIME AND SEI-I＇ING： A case-control study was performed at the Buddhist Tzu chi General hospital from July 2006 to May 2009. PARTIcIPANTS： A total of 30 patients, comprising 15 males and 15 females, who presented with chronic epilepsy and repetitive generalized tonic-clonic seizures according to International League Against Epilepsy guidelines （ILAE, 1989）, were selected. In addition, 30 matched, healthy volunteers were selected as controls. METhODS： Lead I electrocardiogram was performed in the epilepsy and control groups for 5 minutes during a daytime interictal period. Frequency-domain analysis of heart rate variability was performed using fast Fourier transformation. MAIN OUTcOME MEASURES： heart rate interval, high frequency （hF; 0.15-0.45 hz） power, low frequency （LF; 0.04-0.15 hz） power, and LF/（hF ＋ LF） expressed in normalized units （LF%）. RESULTS： compared with the control group, the epilepsy group exhibited a significantly lower mean heart rate interval and hF power, but a significantly greater LF% （P〈 0.01）. There was no significant difference in LF power between the groups （P = 0.17）. cONcLUSION： Patients with chronic epilepsy exhibited faster heart rates during interictal periods, which could contribute to hiclher sympathetic and lower parasympathetic activities.

Acta Mathematica Sinica,English Series 2012年第12期28卷 2365-2372页

作者： Johannes h.hATTINGh Ossama A.SALEh Lucas c.VAN DER MERWE terry J.WALTERS Department of Mathematics East Carolina University Department of Mathematics University of Johannesburg Department of Mathematics University of Tennessee at Chattanooga

The induced path number p（G） of a graph G is defined as the minimum number of subsets into which the vertex set of G can be partitioned so that each subset induces a path. Broere et hi. proved that if G is a graph of order n, then 〈 p（G）＋ p（G）〈3n/2] . In this paper,_we characterize [3n/2], improve the lower bound on p（G）＋ p（G） by one when the graphs G for which p（G） -4- p（G） = 3n n is the square of an odd integer, and determine a best possible upper bound for p（G）＋ p（G） when neither G nor G has isolated vertices.

Improved thromboresistance and analytical performance of intravascular amperometric glucose sensors using optimized nitric oxide release coatings

引用

chinese chemical Letters 2015年第4期26卷 464-468页

作者： Alexander K.Wolf Yu Qin terry c.Major Mark E.Meyerhoff Department of chemistry University of Michigan Department of chemistry Nanjing University Department of Surgery University of Michigan

In this work, nitric oxide （NO） release coatings designed for intravenous amperometric glucose sensors are optimized through the use ofa polylactic acid （PLA） layer doped with a lipophilic diazeniumdiolated species that releases NO through a proton-driven mechanism. An Elast-Eon E2As polyurethane coating is used to both moderate NO release from the sensor surface and increase the sensor＇s linear detection range toward glucose. These sensors were evaluated for thromboresistance and in vivo glucose performance through implantation in rabbit veins. By maintaining NO flux on a similar scale to endogenous endothelial cells, implanted glucose sensors exhibited reduced surface clot formation which enables more accurate quantitative glucose measurements continuously. An in vivo time trace of implanted venous sensors demonstrated glucose values that correlated well with the discrete measurements of blood samples on a benchtop point-of-care sensor-based instrument. The raw measured currents from the implanted glucose sensors over 7 h time periods were converted to glucose concentration through use of both a one-point in vivo calibration and a calibration curve obtained in vitro within a bovine serum solution. control sensors, assembled without NO release functionality, exhibit distinctive surface clotting over the 7 h in vivo implantation period.

Review of literature: Role of 5-aminolevulinic acid and sleep

引用

World Journal of Neuroscience 2013年第4期3卷 307-312页

作者： Michael h. Perez Beatriz L. Rodriguez terry T. Shintani terry T. Shintani Rosanne c. harrigan Department of complementary and Alternative Medicine John A. Burns School of Medicine University of Hawaii Manoa USA

Objective: To determine if current peer-reviewed literature supports the existence of a relationship between the administration of dietary supplements containing 5-Aminolevulinic Acid (5-ALA) and sleep. Methods: conceptual analysis of a systematically defined group of data is based on publications in referred journals. constant comparative analyses were used to analyze the data. Detailed analyses were used to identify trends that led to qualifying relationships between the use of 5-ALA and heme. In addition, the relationship among heme, melatonin, and sleep were explored. Since there were no published data related to 5-ALA and sleep, an analysis of what is known about 5-ALA and heme was undertaken. Results: currently, within the scope of this review, no literature available directly connecting 5-ALA and sleep was found. Research indicates that 5-ALA has an indirect relationship with intra-cellular energy production, which could result in a wide range of effects fromcellular to endocrine to neurologic to behavioral. In addition, there is evidence that 5-ALA may influence tryptophan and serotonin levels. conclusion: While there are no studies on 5-ALA and sleep were found, current research suggests several potential mechanisms by which 5-ALA could influence sleep. The mechanisms suggest the potential for 5-ALA to assist in the adjustment of a person’s circadian cycle, endocrine function, or neurologic function in order to allow for better sleep in a natural way. In doing so, it may provide for a safer alternative to currently available sleep medication. Further research is needed to explore this possibility.

The Role of 5-Aminolevulinic Acid (5-ALA) and Sleep

引用

International Journal of clinical Medicine 2013年第10期4卷 1-7页

作者： Michael h. Perez terry T. Shintani Beatriz L. Rodriguez James Davis Rosanne c. harrigan Department of complementary and Alternative Medicine University of Hawaii John A. Burns School of Medicine Honolulu USA Department of complementary and Alternative Medicine University of Hawaii John A. Burns School of Medicine Honolulu USA Department of Geriatric Medicine University of Hawaii John A. Burns School of Medicine Honolulu USA

Objective: To determine if there is a relationship between the administration of the dietary supplement containing 5-Aminolevulinic Acid (5-ALA) and sleep. Methods: A double-blind, randomized parallel-group study was conducted. It was a 4-month study of 40 participants between the ages of 40 and 70. Males and females were recruited equally. There were 20 in each group who had existing sleep disorders. The tool used to measure participant sleep improvement included the Pittsburgh Insomnia Rating Scale-20 Question (PIRS-20). Improved sleep is reflected when the total PIRS-20 score is lower. Results: Improvement in sleep in the group taking 50 mg 5-ALA, compared to controls, was significant. The mean change, from baseline through week 6, was -5.67 units less on the sleep scale than the control group with a p value of 0.001. The mean change from week 6 to week 10 when the participant was no longer taking the supplement was 4.55 units higher than the control group with a p value of 0.062, which is of borderline significance. conclusions: There is a relationship between the administration of dietary supplements containing 5-ALA and sleep. The results of this study suggest that 5-ALA is associated with improved sleep. The mechanism for sleep improvement needs to be explored. Further research is warranted.

Differential impact of aging and gender on lipid and lipoprotein profiles in a cohort of healthy chinese Singaporeans

引用

Asian Journal of Andrology 2007年第6期9卷 787-794页

作者： Victor h. h. Goh terry Y. Y. Tong helen P. P. Mok Baharudin Said Department of Obstetrics and Gynecology National University of Singapore National University Hospital Kent Ridge 119074 Singapore core Lab at General clinical Research center LA Biomed Harbor-UCLA Medical Center and Department of Medicine Division of Endocrinology David Geffen School of Medicine at UCLA 1124W Carson Street Torrance CA 90502 USA

Aim： To evaluate the impact of age and gender on lipid and lipoprotein profiles and the burden of dyslipidemia in a cohort of healthy chinese Singaporean. Methods： A total of 1 775 healthy chinese, 536 men and 1 239 women aged between 30 and 70 years old were involved in the present study. Results： Gender differences in all lipid and lipoprotein levels were clearly evident. Singaporean chinese men have significantly higher levels of total cholesterol （Tc）, triglyceride （TG）, low density lipoprotein-cholesterol （LDL-c） and total cholesterol/high density lipoprotein-cholesterol （Tc/hDL-c）, and lower levels of hDL-c than women. Although lipid and lipoprotein levels in men did not change in the different age groups, those in women, especially Tc, LDL-c and Tc/hDL-c, were significantly higher in older women （〉 50 years old） than corresponding levels in younger women （30-46 years old）. Furthermore, TG was significantly correlated with lipids and lipoproteins differently in men and women. If 100 mg/dL of LDL-c were to be adopted as the therapeutic cut-off level, then the burden of care will be huge as approximately 90% of both chinese men and women have LDL-c greater than 100 mg/dL. condusion： In light of the findings of the present study, we suggest that preventive measures to promote the reduction in risk of coronary heart disease （chD） must address the high proportion of men and women with high LDL-c, and that these measures should take into account both the gender and age factors. For men, reduction of high cholesterol must start early in life, whereas for women, steps must be taken earlier to mitigate the anticipated sharp increase in risk, especially after menopause.
