IANR Day

We are called to great work, you and I. We are called to fulfill the mission of the land-grant university, and I consider that as much a distinct honor as it is a serious responsibility. I am so pleased to be able to meet that honor and that responsibility by working with all of you, and I’m delighted to talk with you today. While I haven’t had the opportunity to meet everyone in this room, I’ve certainly been glad for all the opportunities that have arisen to meet some of you. And I look forward to getting to know others. I am excited to be here in Nebraska, and I’m enthusiastic about all I think we can do, working together, to advance the mission of the Instituted and the University, and to be of service to the citizens of Nebraska.

Plattsmouth Rotary February Meeting (Farmer's Day Program)

Good afternoon. It's a pleasure to be with you here in Plattsmouth today, and I am particularly pleased to be part of your Farmer's Day program. Because I am so new to Nebraska and the University of Nebraska Institute of Agriculture and Natural Resources, I am trying to learn as much as I can about how the Institute connects with the state, annd how you feel we can be an even better partner with Nebraska. I'm curious about our work in each Nebraska county, and because I was coming to Cass County today, I asked those I work with for some figures on how the Institute is part of the lives of Cass Countians.

Japanese Ag Training Program Closing Ceremony

What a pleasure it is to be here with you tonight for this year’s closing ceremony for the Japanese Ag Training Program. We have been so delighted to have those of you enrolled in the program studying with us for the past three months. You join the nearly 1,400 Japanese Ag Training Program trainees who have received animal science production, management, and agribusiness training from our faculty since the program began here in 1966, and we are so pleased to have had this opportunity to know and to work with you.

Opening Remarks for Master Conservationist Presentations

It is a distinct honor for me to help recognize the 2003 Master Conservationists tonight. Tonight's event marks the 20th anniversary of the program sponsored by the Omaha World-Herald and the Institute of Agriculture and Natural Resources at the University of Nebraska-Lincoln.

UAAD Founders' Day

Because today is the birthday of Thomas Edison who was born in 1847 in Ohio, I suppose that you would expect me as today's speaker to have a special obligation to be inventive. Some of you probably know that for several years, Edison's birthday has been observed as National Science Youth Day, which sounds to me like a rather interesting invention itself. Youth is not a science and science is certainly not a youth, but I am perfectly willing to go along with the national celebration and wish a happy birthday to any science youth that I might happen to encounter. I would encourage you to do the same.

Opening Comments Before Master Conservationist Presentations

It is a real pleasure to participate in this recognition program honoring the 2004 Master-Conservationists. We are grateful for the partnership with the Omaha World Herald in this unique program. In an effort to keep the program in tune with current developments in soil and waster conservation, a special committee is considering the idea of including conservation easements in the 2005 program. Some members of the committee are in the audience tonight. We appreciate the efforts of members of the Omaha World Herald, Natural Resources Districts, the USDA Natural-Resources Conservation Service and the Institute of Agriculture and Natural Resources in carrying out this program.

2006 East Campus Arbor Day Celebration

It cannot be lost on those of us present here today that Nebraska, the land of tall skies and wide prairies, where early settlers saw grass roll to the horizon broken only by the call of the lark, is the home of Arbor Day. Nebraska is, indeed, the tree planter state.

2007 East Campus Arbor Day Celebration

As we celebrate Arbor Day, it seems fitting to begin with a J. Sterling Morton quote. "The cultivation of trees is the cultivation of the good, the beautiful, and the ennobling in man,” Morton once said, adding, "and for one, I wish to see it become universal."

KRVN - Gudmundsen Field Day

John, the Institute of Agriculture and Natural Resources has various locations throughout Nebraska for research and educational purposes. One such location is the Gudmundsen Sandhills Laboratory, which this past week was the site for the annual Youth Field Day.

OPENING REMARKS - THIRD VERTEBRATE PEST CONFERENCE

To open this Third Vertebrate Pest Conference is a real privilege. It is a pleasure to welcome all of you in attendance, and I know there are others who would like to be meeting with us, but, for one reason or another cannot be. However, we can serve them by taking back the results of discussion and by making available the printed transactions of what is said here. It has been the interest and demand for the proceedings of the two previous conferen- ces which, along with personal contacts many of you have with the sponsoring committee, have gauged the need for continuing these meetings. The National Pest Control Association officers who printed the 1962 proceedings still are supplying copies of that conference. Two reprintings of the 1964 conference have been necessary and repeat orders from several universities indicate that those proceedings have become textbooks for special classes. When Dr. Howard mentioned in opening the first Conference in 1962 that publication of those papers would make a valuable handbook of animal control, he was prophetic, indeed. We are pleased that this has happened, but not surprised, since to many of us in this specialized field, the conferences have provided a unique opportunity to meet colleagues with similar interests, to exchange information on control techniques and to be informed by research workers of problem solving investigations as well as to hear of promising basic research. The development of research is a two-way street and we think these conferences also identify areas of inadequate knowledge, thereby stimulating needed research. We have represented here a number of types of specialists—animal ecologists, public health and transmissible disease experts, control methods specialists, public agency administration and enforcement staffs, agricultural extension people, manufacturing and sale industry representatives, commercial pest control operators, and others—and in addition to improving communications among these professional groups an equally important purpose of these conferences is to improve understanding between them and the general public. Within the term general public are many individuals and also organizations dedicated to appreciation and protection of certain animal forms or animal life in general. Proper concepts of vertebrate pest control do not conflict with such views. It is worth repeating for the record the definition of "vertebrate pest" which has been stated at our previous conferences. "A vertebrate pest is any native or introduced, wild or feral, non-human spe- cies of vertebrate animal that is currently troublesome locally or over a wide area to one or more persons either by being a general nuisance, a health hazard or by destroying food or natural resources. In other words, vertebrate pest status is not an inherent quality or fixed classification but is a circumstantial relationship to man's interests." I believe progress has been made in reducing the misunderstanding and emotion with which vertebrate pest control was formerly treated whenever a necessity for control was stated. If this is true, I likewise believe it is deserved, because control methods and programs have progressed. Control no longer refers only to population reductions by lethal means. We have learned something of alternate control approaches and the necessity for studying the total environment; where reduction of pest animal numbers is the required solution to a problem situation we have a wider choice of more selective, safe and efficient materials. Although increased attention has been given to control methods, research when we take a close look at the severity of animal damage to so many facets of our economy, particularly to agricultural production and public health, we realize it still is pitifully small and slow. The tremendous acceleration of the world's food and health requirements seems to demand expediting vertebrate pest control to effectively neutralize the enormous impact of animal damage to vital resources. The efforts we are making here at problem delineation, idea communication and exchange of methodology could well serve as both nucleus and rough model for a broader application elsewhere. I know we all hope this Third Conference will advance these general objectives, and I think there is no doubt of its value in increasing our own scope of information.

Effect of a low-level laser on bone regeneration after rapid maxillary expansion

Introduction: In this study, we evaluated the effects of a low-level laser on bone regeneration in rapid maxillary expansion procedures. Methods: Twenty-seven children, aged 8 to 12 years, took part in the experiment, with a mean age of 10.2 years, divided into 2 groups: the laser group (n=14), in which rapid maxillary expansion was performed in conjunction with laser use, and the no-laser group (n=13), with rapid maxillary expansion only. The activation protocol of the expansion screw was 1 full turn on the first day and a half turn daily until achieving overcorrection. The laser type used was a laser diode (TWIN Laser; MMOptics, Sao Carlos, Brazil), according to the following protocol: 780 nm wavelength, 40 mW power, and 10 J/cm(2) density at 10 points located around the midpalatal suture. The application stages were 1 (days 1-5 of activation), 2 (at screw locking, on 3 consecutive days), 3, 4, and 5 (7, 14, and 21 days after stage 2). Occlusal radiographs of the maxilla were taken with the aid of an aluminum scale ruler as a densitometry reference at different times: T1 (initial), T2 (day of locking), T3 (3-5 days after T2), T4 (30 days after T3), and T5 (60 days after T4). The radiographs were digitized and submitted to imaging software (Image Tool; UTHSCSA, San Antonio, Tex) to measure the optic density of the previously selected areas. To perform the statistical test, analysis of covariance was used, with the time for the evaluated stage as the covariable. In all tests, a significance level of 5% (P<0.05) was adopted. Results: From the evaluation of bone density, the results showed that the laser improved the opening of the midpalatal suture and accelerated the bone regeneration process. Conclusions: The low-level laser, associated with rapid maxillary expansion, provided efficient opening of the midpalatal suture and influenced the bone regeneration process of the suture, accelerating healing.

Prevalence of Arterial Hypertension Among Seventh-Day Adventists of the Sao Paulo State Capital and Inner Area

Background: Inadequate life habits are known to favor hypertension, and Adventists recommend healthy life habits. Objective: To assess the prevalence of hypertension among Seventh-Day Adventists from the inner Sao Paulo state and Sao Paulo state capital. Methods: This study assessed 264 Adventists (mean age, 41.17 +/- 15.27 years; women, 59.8%) with a high religiosity level assessed by use of the Duke University Religion Index. Blood pressure was measured with a validated automatic device. The significance level adopted was p < 0.05. Results: The total prevalence of hypertension was 22.7% (27.4% in the inner state and 15% in the capital). The Adventists from the capital differed from those of inner state as follows (p < 0.05), respectively: higher education (62% vs 36.6%); employed by a third party (44%) vs self-employed (40.9%); family income (8.39 +/- 6.20 vs 4.59 +/- 4.75 minimum wages); individual income (4.54 +/- 5.34 vs 6.35 +/- 48; couple responsible for family income (35% vs 39.6%); vegetarianism (11% vs 3%); blood pressure (115.38 +/- 16.52/68.74 +/- 8.94 vs 123.66 +/- 19.62/74.88 +/- 11.85 mmHg); white ethnicity (65% vs 81.1%); married (53% vs 68.9%); lower tangible support in the social aspect (15.7 +/- 5.41 vs 16.9 +/- 4.32); and recalling the last time one's blood pressure was measured (65% vs 48.8%). On multivariate analysis, hypertension associated with the following: 1) vegetarianism (OR 0.051; 95% CI: 0.004-0.681); 2) educational level (OR 5.317; 95% CI: 1.674-16.893); 3) recalling the last time one's blood pressure was measured (OR 2.725; 95% CI: 1.275-5.821); 4) being retired (OR 8.846; 95% CI: 1.406-55.668); and 5) being responsible for family income (OR 0.422; 95% CI: 0.189-0.942). Conclusion: The prevalence of hypertension among Adventists was lower as compared with that reported in Brazilian studies, and it was lower in the Sao Paulo state capital as compared with that in the inner Sao Paulo state, possibly because of the better socioeconomic conditions and life habits of the former.
