Cell Ultrastructure In Disease, R. Laschi, E. Govoni

Scanning Electron Microscopy

The doctor of today must adopt the 'cellular way of thinking' in the evaluation of diseases. This ultrastructural outlook provides him with much indispensable information that also serves a practical purpose. A diseased cell organelle is at the basis of every clinical sign and any attempt of therapy must be aimed at that specific point of lesion. We intend, in the light of a long experience, to propose to clinicians a new way of thinking in which a precise correlation between symptoms and sub-microscopic changes of the cell is considered. Many different examples amply justify this proposal. Electron microscopy can …

Magnesium, Copper And Zinc Concentrations In Blood From Children With Diabetes Mellitus, Linda Lowers Jenkins

Chemistry & Biochemistry Theses & Dissertations

Trace element levels in blood from diabetic children were investigated and compared to control children. Plasma, erythrocyte, mononuclear and polymorphonuclear cells were analyzed for magnesium, copper, and zinc content. Leukocyte separation was performed by density gradient centrifugation on Ficoll-Hypaque, followed by washing steps to remove platelet contamination and hypotonic lysis to remove red cell contamination. Polarized Zeeman-effect atomic absorption spectroscopy was used for trace metal analysis.

Decreased plasma magnesium levels were observed in the diabetic children. This finding is well documented and probably due to increased urinary magnesium loss from glycosuria. Lymphocyte magnesium levels in the diabetic children were also …

The Effects Of Luteinizing Hormone And Adenosine 3',5'-Cyclic Monophosphate On Phospholipid Metabolism By Luteal Mitochondria, Jim John Sadighian

Chemistry & Biochemistry Theses & Dissertations

Luteinizing hormone (LH) increases intracellular concentrations of adenosine 3', 5 '-cyclic monophosphate and the phosphoinositides, phosphatidylinositol (PI), PI 4'-phosphate (PIP) and PI 4' .5 1 - bispbosphate (PIP₂). It is believed that cAMP and the phosphoinositides act concertedly to regulate mitochondrial conversion of cholesterol to pregnenolone. This study examined the effects of LH and N⁶ ,O² -dibutyryl cAMP (dbcAMP) on phospholipids metabolism by luteal mitochondria and the influence of dbcAMP and the phosphoinosi tides on mitochondrial steroid production. Mitochondria were isolated from unincubated and incubated luteal tissue by differential centrifugation. Phospholipids were extracted from the mitochondria …

Calcium And Cystic Fibrosis, Godfried M. Roomans

Scanning Electron Microscopy

Cystic fibrosis (CF) is a generally lethal, congenital, genetic disease of unknown etiology. It is likely that a defective regulation of ion and water transport in exocrine glands and possibly also in other epithelial cells has a central role in the pathogenesis of this disease. Calcium has been implicated in the basic defect underlying CF because of findings of abnormally high calcium levels in some secreted fluids and some cells of CF patients.

Using X-ray microanalysis, we have demonstrated elevated calcium concentrations in cultured fibroblasts and in goblet cells of the bronchial epithelium of CF patients. A factor produced by …

Respiratory Viruses And Antibodies In Preconditioned South Dakota Feeder Calves, M.L. Vickers, R.H. Pritchard

South Dakota Beef Report, 1986

Nasal swabs and blood samples were taken from a t o t a l of 400 calves on a preconditioning evaluation program during 2 years. Fifty calves from each of four South Dakota ranches were divided into preconditioned (PC) and control (CO) groups and sampled both on the ranch and in the feedlot. The preconditioning program followed the recommendations of the South Dakota Beef Cattle Improvement Association and the Extension Service and included vaccination with live virus vaccines for infectious bovine rhinotracheitis (IBR), bovine viral diarrhea (BVD) and parainfluenza-3 virus (PI3). In both years, viruses were isolated from calves on …

Performance Of Flank Spayed Rumen Autografted Heifers, David L. Whittington

South Dakota Beef Report, 1986

Flank spaying of intact yearling heifers has been a routine procedure for ranchers for several years. Most recently a new technique called rumen autografting has created a lot of interest with ranchers. The technique involves implanting or grafting a small piece of ovarian tissue into the outside lining of the rumen wall. A trial was initiated on May 14, 1986, to compare summer grazing performance of intact flank spayed and rumen autografted heifers with and without a growth implant. The 231 crossbred heifers were randomly allotted to the trial and grazed together for 99 days as one herd. The results …

The Release Of Insects Sterilized By Colbalt 60 To Control A Wild Population Of Stable Flies At The Sdsu Beef Cattle And Sheep Nutrition Unit In Brookings, Emmert R. Easton, Michael A. Catangui

South Dakota Beef Report, 1986

Sterile stable flies were released weekly a t the SDSU Beef Cattle and Sheep Nutrition Unit at Brookings from July 24 through September during the summer 1986 season t o eliminate wild populations of insects. Flies that were sterilized were marked with a dye so when recaptured by an insect net or a sticky trap they could be differentiated from wild, normal or fertile flies. A trend toward reduced f l y numbers was observed 3 weeks following the first release. A 1:5 ratio of sterile to wild flies was achieved in 6 weeks.

Chemistry Faculty Publications

Glutamate dehydrogenase (GDH) activity was determined in high-speed fractions (1 00,000 g for 60 min) obtained from whole rat brain homogenates after removal of a low-speed pellet (480 g for 10 min). Approximately 60% of the high-speed GDH activity was particulate (associated with membrane) and the remaining was soluble (probably of mitochondrial matrix origin). Most of the particulate GDH activity resisted extraction by several commonly used detergents, high concentration of salt, and sonication; however, it was largely extractable with the cationic detergent cetyltrimethylammonium bromide (CTAB) in hypotonic buffer solution. The two GDH activities were purified using a combination of hydrophobic …

Genetic Engineering Of Livestock Improvement, Gordon E. Dickerson

World Congress on Genetics Applied to Livestock Production: 3rd (1986)

Genetic engineering requires clearly defined objectives, adequate genetic variability and effective methods of selection. In a given production-marketing System, relative importance of genetic change in alternative traits can be estimated from expected effects on cost per unit of output, using available biological and economic information. Diversity among existing breeds and their crosses is a primary and quickly usable genetic resource, and its management for future needs is a public concern. Better physiological and biochemical understanding of the genetic controls of animal development and function is important to permit more effective selection for efficiency of animal production under diverse environments. Long-term …

Heg86-210 Being A 'Grand' Parent, Herbert G. Lingren

University of Nebraska-Lincoln Extension: Historical Materials

This guide explores grandparenting, including the benefits derived from being a grandparent, suggestions on how to be a good grandparent, precautions to take when grandchildren come for a visit, and ways to have fun with grandchildren.

Grandparents Today

Approximately 75 percent of Americans over 65 have living grandchildren, according to a 1975 Harris poll. Most grandparents begin their role during middle age. The average age for becoming a grandmother is 46 and may be as early as 32. This means we need to set aside many outdated ideas about grandparent. They are active people. They do not necessarily get around …

Columnaris Disease Of Fishes, G. L. Bullock, T. C. Hsu, E. B. Shotts Jr.

United States Fish and Wildlife Service: Publications

Columnaris disease is an acute to chronic bacterial infection that affects anadromous salmonids and virtually all species of warmwater fishes. Davis (1922), who first described the disease, named it columnaris because the causal bacterial cells seen in wet mounts of affected gills and fins were arranged in columnar aggregations. Ordal and Rucker (1944) were the first to isolate the causal organism and, based on cellular morphology, identified it as a myxobacterium. Organisms classified in the order Myxobacterales are long, thin gram-negative rods that are motile on agar media by a creeping or flexing motion. They have a life cycle composed …

The importance of nonindustrial private forest( NIPF) lands to national timber output potential is well-documented (USDA Forest Service 1981, 1982; Wall 1981). The NIPF sector controls 58 percent of the Nation's commercial fm·est area, compared to 14- percent in forest industry holdings, and 28 percent in public forests (Figure 1). Approximately 71 percent of the commercial forest area in the eastern United States is held by the NIPF sector.

Wilderness And Natural Areas In The Eastern United States: A Management Challenge, David Kulhavy, Richard N. Conner

Faculty Publications

"The purpose of this symposium is not to debate either the concept of wilderness or the amount of wilderness appropriate for the United States. These are not debatable issues for present purposes. The Congress has spoken twice. The Wilderness Act of 1964 (PL 88-577) and the amendments of 1975, known as the "Eastern Wilderness Act" (PL 93-622), both set-aside existing areas as wilderness and established procedures for consideration of additions to the wilderness system. The purpose of this symposium is to consider the management of wilderness areas over time. In a very real sense, if those areas established as wilderness …

Fluorescence Characterization Of The Mature Caryopsis Of Sorghum Bicolor (L.) Moench, C. F. Earp, L. W. Rooney

Food Structure

Fluorescence microscopy was used to characterize the mature car yaps is of Sorghum bicolor (L.) Moench . Acid Fuchsin, a protein specific dye used in bright field microscopy, caused protein bodies and matrix in the sorghum endosperm to fluoresce. ANS (8-ani lino-1- naphthal e ne sulfonic acid) also caused the protein bodi es and matrix in the endosperm to fluoresce. Varietal differences in endosperm protein dist r ibution were evident when viewed after sta · ning with Acid Fuchsin .

Ultrastructure Of Cooked Spaghetti, M. A. Pagani, D. J. Gallant, B. Bouchet, P. Resmini

Food Structure

Several electron microscopy (EM) complementary techniques (scanning electron microscopy, freeze-fracturing and thin-sectioning) have been applied in the ultrastructural study of spaghetti.

Experimental spaghetti have been produced starting from two semolinas from the same wheat cultivar and using a low temperature (LT) and very high temperature (VHT) drying schemes.

Cooking quality of these products was not related to the quantity of the main components present in semolina. however, the drying conditions (temperature and humidity) and the nature of the cooking water greatly influenced cooking characteristics.

The three EM techniques were used to detected differences in protein and starch organization in relationship …

Action Of Polyphosphates In Meat Products, D. F. Lewis, Kathleen H.M. Grooves, J. Hilary Holgate

Food Structure

The action of polyphosphates on meats has been examined in studies using different meats and has been compared with other treatments. The results were monito red by recording cooked yield and observing changes in structure by electron microscopy. Four possible characteristics of polyphosphates are considered: pH, sequestering action, ionic strength and as an ATP (adenosine triphosphate) analogue. In the conditions used in these experiments, the pH-buffering effect of polyphosphates is found as the principal characteristic in meat products.

Some meats were found to be more affected by polyphosphates than others and:. hypothesis is developed to explain this. It is proposed …

Microscopal Observations On The Structure Of Bacon, C. A. Voyle, P. D. Jolley, G. W. Offer

Food Structure

Commercially processed salt-treated pig longissimus dorsi muscle, in the form of bacon slices, sometimes shows localized variations in the light-scattering properties of the tissue. The phenomenon is described as 'tiger-stripe'. A study of areas of tissue showing such variations, using electron microscopy, has revealed differences in the structure at the myofibrillar level. Areas which appear dark when viewed by incident illumination show ordered myofibrillar structure, whereas areas which appear light under similar viewing conditions appear to be disordered.
