American journal of Plant Sciences 2024年第3期15卷 180-192页

作者： Robert B. Mitchell Daren D. Redfearn Kenneth P. Vogel terry j. Klopfenstein Galen Erickson P. Stephen Baenziger Bruce E. Anderson Mary E. Drewnoski jay Parsons Steven D. Masterson Marty R. Schmer Virginia L. jin USDA-ARS Wheat Sorghum and Forage Research Unit University of Nebraska-Lincoln Lincoln NE USA Department of Agronomy and Horticulture University of Nebraska-Lincoln Lincoln NE USA Department of Animal Science University of Nebraska-Lincoln Lincoln NE USA Department of Agricultural Economics University of Nebraska-Lincoln Lincoln NE USA USDA-ARS Agroecosystem Management Research Unit University of Nebraska-Lincoln Lincoln NE USA

In addition to their value as cereal grains, wheat (Triticum aestivum L.) and triticale (× Triticosecale Wittmack) are important cool-season annual forages and cover crops. Yearling steer (Bos taurus) performance was compared in the spring following autumn establishment as for age cover crops after soybean [Glycine max (L.) Merr.] grain harvest. Replicated pastures (0.4 ha) were no-till seeded in three consecutive years into soybean stubble in autumn, fertilized, and grazed the following spring near Ithaca, NE, USA. Each pasture (n = 3) was continuously stocked in spring with four yearling steers (380 ± 38 kg) for 17, 32, and 28 d in 2005, 2006, and 2007, respectively. In 2005, average daily gain (ADG) for steers grazing triticale exceeded the ADG for wheat by 0.31 kghd-1d-1. In 2006, wheat ADG exceeded that for triticale by 0.12 kghd-1d-1. In 2007, steers grazing wheat lost weight, while steers grazing triticale gained 0.20 kghd-1d-1. Based on the 3-year average animal gains valued at $1.32 kg-1, mean net return ($ ha-1 yr-1) was $62.15 for triticale and $22.55 for wheat. Since these grazed cover crops provide ecosystem services in addition to forage, grazing could be viewed as a mechanism for recovering costs and adds additional value to the system. Based on this 3-year grazing trial, triticale was superior to wheat and likely will provide the most stable beef yearling performance across years with variable weather for the western Cornbelt USA.

Effects of chronic epilepsy on heart rate variability A case-control study

引用

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.

(Q)SAR modelling of nanomaterial toxicity:A critical review

引用

Particuology 2015年第4期13卷 1-19页

作者： Ceyda Oksel Cai Y.Ma jing j.Liu terry Wilkins Xue Z.Wang Institute of Particle Science and Engineering School of Chemical and Process EngineeringUniversity of Leeds School of Chemistry and Chemical Engineering South China University of Technology

There is increasing recognition that some nanomaterials may pose a risk to human health and the environment. Moreover, the industrial use of the novel engineered nanomaterials （ENMs） increases at a higher rate than data generation for hazard assessment; consequently, many of them remain untested. The large number of nanomaterials and their variants （e.g., different sizes and coatings） requiring testing and the ethical pressure towards nonanimal testing means that in a first instance, expensive animal bioassays are precluded, and the use of（quantitative） structure-activity relationships （（Q）SARs） models as an alter- native source of （screening） hazard information should be explored. （Q）SAR modelling can be applied to contribute towards filling important knowledge gaps by making best use of existing data, prioritizing the physicochemical parameters driving toxicity, and providing practical solutions for the risk assessment problems caused by the diversity of ENMs. This paper covers the core components required for successful application of （Q）SAR methods to ENM toxicity prediction, summarizes the published nano-（Q）SAR studies, and outlines the challenges ahead for nano-（Q）SAR modelling. It provides a critical review of （1） the present availability of ENM characterization/toxicity data, （2） the characterization of nanostructures that meet the requirements for （Q）SAR analysis, （3） published nano-（Q）SAR studies and their limitations, （4） in silico tools for （Q）SAR screening of nanotoxicity, and （5） prospective directions for the development of nano-（Q）SAR models.

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.

Is there an acute exercise-induced physiological/biochemical threshold which triggers increased speed of cognitive functioning? A meta-analytic investigation

引用

journal of Sport and Health Science 2015年第1期4卷 4-13页

作者： terry Mc Morris Beverley j.Hale Department of Sport and Exercise Science University of ChichesterCollege Lane

Purpose： The purpose of this study was to examine, using meta-analytic measures, the evidence regarding the optimal exercise intensity at which improvements in speed of cognitive function are triggered. Specifically, it was hypothesized that the catecholamine, lactate, and ventilatory thresholds is the point at which significant improvements in speed of cognitive function are observed. Methods： We compared mean effect sizes for threshold studies and for those studies where exercise intensity was classed as moderate （40%-- 79% VO2 or equivalent） but in which the thresholds were not measured. Results： Random effects meta-analysis showed significant, moderate, mean effect sizes for studies at the threshold （g = 0.58, Z = 2.98, p 〈 0.003） and for those during moderate intensity exercise but in which the threshold was not measured （ g = 0.54, Z = 5.0l, p 〈 0.001）. There was no significant difference between mean effect sizes, which suggests that the thresholds are unlikely to represent a trigger point. Conclusion： Moderate intensity exercise, even below the thresholds, can induce improved speed of cognition, possibly due to a combination of increased peripheral catecholamine concentrations inducing vagal/nucleus tractus solitarii pathway activation and central increases due to perceptions of stress.

AIM:To understand the demographic characteristics of patients in Southwestern Ontario,Canada with ulcerative colitis(UC)in order to predict disease severity. METHODS:Records from 1996 to 2001 were exam- ined to create a database of UC patients seen in the London Health Sciences Centre South Street Hospital Inflammatory Bowel Disease *** be included, patients'charts were required to have information of their disease presentation and a minimum of 5 years of *** were reviewed using standardized data collection *** severity was generated during the chart review process,and non-endoscopic Mayo Score criteria were collected into a composite. RESULTS:One hundred and two consecutive patients'data were entered into the *** analyses revealed that 51%of the patients were male, the mean age at diagnosis was 39 years,13.7%had a first degree relative with inflammatory bowel disease (IBD),61.8%were nonsmokers and 24.5%were *** 22.5%of patients the disease was limited to the rectum,in 21.6%disease was limited to the sigmoid colon,in 22.5%disease was limited to the left colon,and 32.4%of patients had pancolitis. Standard multiple regression analysis which regressed a composite of physician global assessment of disease severity,average number of bowel movements,and average amount of blood in bowel movements on year of diagnosis and age at time of diagnosis was significant,R 2=0.306,F(7,74)=4.66,P<0.01. Delay from symptoms to diagnosis of UC,gender, family history of IBD,smoking status and disease severity at the time of diagnosis didnot significantly predict the composite measure. CONCLUSION:UC severity is associated with younger age at diagnosis and year of diagnosis in a longitudinal cohort of UC patients,and may identify prognostic UC indicators.

Successful fracture healing requires the simultaneous regeneration of both the bone and vasculature;mesenchymal stem cells (MSCs) are directed to replace the bone tissue, while endothelial progenitor cells (EPCs) form the new vasculature that supplies blood to the fracture site. In the elderly, the healing process is slowed, partly due to decreased regenerative function of these stem and progenitor cells. MSCs from older individuals are impaired with regard to cell number, proliferative capacity, ability to migrate, and osteochondrogenic differentiation potential. The proliferation, migration and function of EPCs are also compromised with advanced age. Although the reasons for cellular dysfunction with age are complex and multidimensional, reduced expression of growth factors, accumulation of oxidative damage from reactive oxygen species, and altered signaling of the Sirtuin-1 pathway are contributing factors to aging at the cellular level of both MSCs and EPCs. Because of these geriatric-specific issues, effective treatment for fracture repair may require new therapeutic techniques to restore cellular function. Some suggested directions for potential treatments include cellular therapies, pharmacological agents, treatments targeting age-related molecular mechanisms, and physical therapeutics. Advanced age is the primary risk factor for a fracture, due to the low bone mass and inferior bone quality associated with aging;a better understanding of the dysfunctional behavior of the aging cell will provide a foundation for new treatments to decrease healing time and reduce the development of complications during the extended recovery from fracture healing in the elderly.
