Assessing the Potential Use of Teff as an Alternative Grain Crop in Virginia
Teff (Eragrostis tef (Zucc.)) is an annual, warm-season cereal crop most notable for its gluten-free, nutrient-packed seed. Experiments were conducted in two regions of Virginia (Blacksburg and Steeles Tavern) in 2010 and 2011 to determine the grain production potential of two teff varieties (brown …

Rheology and microscopy of low calorie mayonnaise-type emulsions made with stearic acid- modified maize and teff starches
… can be used as fat replacer in low fat foods. Teff (a cereal indigenous to Africa, which is underutilized and underresearched) and maize starches modified with stearic acid (a naturally occurring fatty acid), has resulted in a paste with reduced gelling ability and higher viscosity in previous …

Nitrogen Rate and Source Effects on Biomass Yield of Teff Grown for Livestock Feed in the Mid-Atlantic Region
Teff (Erogrostis tef (Zucc.)), an annual warm-season grass from Ethiopia, has potential to provide forage during periods when cool-season grass growth is limited by high temperatures. An experiment was conducted at three Virginia locations in 2009 and 2010 to determine the effect of nitrogen (N) …

Mechanisms Mediating Asthma Tolerance Induced By Regulatory Dendritic Cells Through CD4+CD25+Foxp3+ T Regulatory Cells
… which the animals-lung Th2 T effector cells (Teff) are displaced by activated Treg cells. Intestinal DCs have been shown to promote oral tolerance by inducing antigen-naïve T cells to differentiate into Treg, but whether DCs can induce Teff to differentiate into Treg remains uncertain. We …

IL-2-Dependent Regulation of Immune Homeostasis and Response to Infection
… on both regulatory T (Treg) and effector T (Teff) cells. However, the precise role of IL-2 in the homeostatic maintenance and function of Treg cells in the adult peripheral immune system remains unclear. Here, we report that neutralization of IL-2 in mice abrogated all IL-2 receptor signaling …

Developing analytical methods to determine physicochemical properties, protein and amino acid composition of African staple foods
… namely, maize, sorghum, cassava, corn-soya and teff. Moisture was determined by Karl Fischer titration, and it was found that corn-soya, sorghum, maize, and teff had moisture levels below the recommended maximum limits. However, cassava revealed a high moisture content which would increase the …

Fundamental studies of sourdoughs fermented with Weissella cibaria and Lactobacillus plantarum: influence on baking characteristics, sensory profiles and in vitro starch digestibility of gluten-free breads
… acids in buckwheat (16.8 ml; 26.0 ml), teff (16.2 ml; 24.5 ml) and quinoa sourdoughs (26.4 ml; 35.3 ml) correlating with higher amounts of fermentable sugars and higher buffering capacities. Sourdough incorporation reduced the crumb hardness after five days of storage in buckwheat (Wc …

EPAC1 AS A THERAPEUTIC TARGET FOR PANCREATIC DUCTAL ADENOCARCINOMA
… of EPAC1 in either Treg or effector T-cells (Teff) decreased Treg-mediated suppression of Teff, while the impact of EPAC1 inhibition/knockout was additive, as determined by an in vitro suppression assay. Mechanistically, inhibition/knockout of EPAC1 up-regulated STAT3 activation and …

Classical models of heavy-ion collisions
… The yield of small clusters is given by the A;;-Teff power law; Teff depends on the collision energy and has a minimum value of Teff""' 1.7, which is also observed in nuclear fragmentation reactions. Two classical nucleon-nucleon interaction models are developed which have the saturation energy …

The effect of mutant replication initiation proteins and antisense RNA to the gene on maize streak virus replication
… crops are rye, common millet, finger millet, teff, sugarcane and sorghum. Many of these are important food crops in most parts of the world, including Africa. The sustainable production of sufficient and affordable food for a rapidly increasing population is one of Africa's greatest challenges.

Evaluation of alternative forage species to reduce risk for cow-calf production systems in the Appalachian region
… combination with endophyte-infected tall fescue, Teff, Bermudagrass (BG), and Caucasian bluestem (CB). Plots were harvested May through October of 2009 and 2010 at the late boot stage at a cutting height of 10cm. Subsamples were analyzed for dry matter and nutritive value. To assess risk, …

Spectroscopic abundances of solar-type dwarfs in open cluster M34 (Ngc 1039)
… and fall in the range 4750 ≤ Teff ≤ 6130 K. Despite modest scatter in Fe, Ti, Cr, Ca, Al, and Mg (none of which is found to be correlated with Li scatter in M34), our two coolest stars are slightly though consistently underabundant in these elements relative to the warmer …

Low-dose IL-2 for T-regulatory cell expansion after alemtuzumab therapy in relapsing-remitting multiple sclerosis
… more sensitive to IL-2 than effector cells (Teffs). Low-dose IL-2 preferentially expands Tregs in patients with a variety of autoimmune disease, correlating with clinical improvement. Autoimmunity is a frequent complication of treatment with the lymphocyte-depleting therapy alemtuzumab in …

Bioaugmentation and biostimulation of a South African coal-based Technosol as a mine rehabilitation strategy
… (0%, 2.5%, 5% and 7% w/w). Eragrostis tef (teff) plants were grown in each of the treatments, including a non-inoculated control. Seasonal teff growth was mimicked by performing a second trial of plant growth studies. Soil health, quality and fertility were determined from assessment of soil …

Effects of Carbon, Nitrogen, Particle size and moisture on Oyster Mushroom Production in KwaZulu Natal - Cedara
… of carbon and nitrogen such as wheat bran, teff, lucerne, bagasse, maize, sawdust, juncao and hominy chop were analysed using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES Analysis). Carbon and nitrogen content was used to set up five carbon/nitrogen (C/N) ratios (15:1, …

Chemical abundance analysis of HE 2324-0215, an r-process-enhanced metal-poor star
… stellar parameters are [Fe/H] = -3.05 ± 0.17, Teff = 4477 K, Vt = 2.70 kms-1 , and log(g) = 0.70, indicating that HE 2324-0215 is a red giant star. The [Eu/Fe] = 0.73 and [Ba/Eu] = -0.68 suggests that this is an r-I star. Since thorium is detectable in this star, we derived the age of the star …

Continuous expression of TOX safeguards exhausted CD8 T cell epigenetic fate
… at cytotoxic genes typically accessible in Teff cells, thus undergoing partial reprogramming into a more functional state. Together, these findings suggest that continuous TOX expression in established Tex acts as a durable epigenetic barrier to reinforce the Tex developmental fate by …

Differential polarization of Hβ in γ CAS
… the polarization profile is used to determine Teff, geff, and v sin i for the underlying star by fitting the Hubeny (1988) atmosphere model. The Be star model developed by Poeckert and Marlborough (1978a) for γ Cas is used as a basis to explain our polarization observations. We have made two …
