Responses Of Astrocytes In Culture After Low Dose Laser Irradiation, David T. Yew, D. R. Zheng, C. Au, W. W. Y. Li

Scanning Microscopy

The effect of Helium-Neon low dose laser on astrocytes was investigated in cultures of isolated astrocytes from albino neonatal rats. The laser appeared to inhibit the growth of astrocytes as exemplified by the smaller sizes of the cells and the decreased leucine uptake in each cell after treatment. Temporary decrease in the number of mitoses was also observed, but this trend was reversed soon after. Electron microscopic studies revealed an increase in buddings from cell bodies and processes (branches) after irradiation.

Nutritive Value Of Rubber Seed (Hevea Brasiliensis) Meal: Utilization By Growing Pigs Of Semipurified Diets In Which Rubber Seed Meal Partially Replaced Soybean Meal, G. M. Babatunde, W. G. Pond, E. R. Peo, Jr.

Department of Animal Science: Faculty Publications

Thirty-six four-way cross (Chester White x Landrace x Large White x Yorkshire) growing bmws and gilts were used to investigate the effects of replacing graded levels of protein from soybean meal with equivalent levels of protein from rubber seed meal in 16% CP semipurified diets on the performance characteristics, hematocrit, plasma metabolites and N utilization of pigs.

Waterlogging : How It Reduces Plant Growth And How Plants Can Overcome Its Effects, Tim Setter, Bob Belford

Journal of the Department of Agriculture, Western Australia, Series 4

Lack of oxygen is the major cause of limited plant growth in waterlogged soils. When soils become waterlogged less gas diffuses to and from the roots through the soil pores; there are changes in concentrations of mineral elements in soil solutions; and toxic products of roots and soil microorganisms begin to accumulate. These changes adversely affect germination, growth and development of plants.

G90-962 Introducing Solid Foods To Babies, Darlene Martin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains when and how to add solid foods to your baby's diet.

Good nutrition is the cornerstone of a baby's growth and development. The American Academy of Pediatrics strongly recommends breast-feeding for most full-term infants. No formula can replace the immunological protection a baby receives from colostrum -- the breast milk produced the first few days after birth. It's important to breast-feed for at least the first few weeks, even if it can't be continued for a long time. If breast-feeding is not your choice, or if it is discontinued before the baby's first birthday, commercially prepared infant …

Efficacy Of The Urea Dilution Technique In Estimating Empty Body Composition Of Pigs Weighing 50 Kilograms, L. I. Chiba, A. J. Lewis, E. R. Peo, Jr.

Department of Animal Science: Faculty Publications

The efficacy of the urea dilution technique in estimating the empty body composition of pigs weighing 50 kg was evaluated in three trials using 17 contemporary (Large White x Landrace x Hampshire x Duroc) and 8 Nebraska Gene Pool x contemporary pigs. Blood samples were collected via ear catheter before infusion (-60, -30 and 0 min) and at various times (3 to 90 min) after urea infusion (2.16 mmol/kg live BW), and analyzed for plasma urea. Backfat thickness of live pigs from the contemporary line was measured ultrasonically. Pigs then were killed by euthanasic injection. and total bodies (with gastrointestinal …

Recruitment And Growth Of Oysters On Shell Planted At Four Monthly Intervals In The Lower Potomac River, Maryland, Reinaldo Morales-Alamo, Roger L. Mann

VIMS Articles

Oyster shells were planted on four successive months (May to August 1986) in contiguous plots at Jones Shore Bar in the Potomac River, Maryland, to study the effect of differences in time of cultch planting on settlement and survival of oyster spat. The plots were usually sampled at two-week intervals from time of planting through November, 1986, and once in June, 1987. A massive concentration of the tunicate Molgula manhattensis covered the bottom in all plots within four to six or eight weeks following shell planting. A commercially acceptable number of spat per shell, between 1.8 and 2.2 (approximately equivalent …

Development Of An Aspen Sucker Stand Following Irrigation And Fertilization, G.W. Wyckoff, D.W. Einspahr, M.K. Benson

Aspen Bibliography

A 16-18 year-old aspen stand was harvested in 1969. Aerial biomass components were determined and soils evaluated. Treatments of fertilizer, irrigation, fertilizer + irrigation and control were applied over a seven year period following harvest. Stand measurements were taken periodically over 18 years. Fertilization produced growth increases of 45-55 percent. Height, diameter, and stems per acre were affected by treatments. Guidelines for fertilizer application were developed from leaf tissue analysis.
