Spontaneous experimental autoimmune encephalomyelitis arises in 100% of mice exclusively harboring myelin basic protein-specific T cells, and can be prevented by a single injection of CD4+ T cells obtained from normal donors. Given the powerful regulatory effect of the transferred T cells, we further investigated their properties, and, in particular, their repertoire requirements. Transfer of m...

Two cultivars of sugarcane (Saccharum officinarum cv. CP73-1547 and CP88-1508) were grown for 3 months in paired-companion, temperature-gradient, sunlit greenhouses under daytime [CO2] of 360 (ambient) and 720 (double ambient) micromol mol(-1) and at temperatures of 1.5 degrees C (near ambient) and 6.0 degrees C higher than outside ambient temperature. Leaf area and biomass, stem biomass and ju...

A gas relay in the transformer, an important non-electricity protection equipment, only triggers stem leaf spring for serious alarm when baffle rotates to a certain angle, which cannot judge transformer fault event of heavy before running state and development process, this paper puts forward kind based on panel corner monitoring methods. The partial structure is improved, signal extracted by i...

in order to evaluate the effects of planting pattern on morphological, phonological, yield and yield components of sweet and super sweet corn (zea mays l.) varieties under saline conditions, a field experiment was conducted as split plots based on a randomized complete block design with four replications. planting pattern in 3 levels included one row in ridge, two row in ridge and furrow planti...

1. Equal masses of sister leaves of Bryophyllum calycinum produce equal masses of shoots and roots in equal time and under equal conditions. 2. The mass of shoots and roots produced by different masses of sister leaves in equal time and under equal conditions is approximately in direct proportion to the masses of the leaves. 3. When a piece of stem inhibits the production of shoots and roots in...

During plant-transpiration, water molecules having the lighter stable isotopes of oxygen and hydrogen evaporate and diffuse at a faster rate through the stomata than molecules having the heavier isotopes, which cause isotopic enrichment of leaf water. Although previous models have assumed that leaf water is well-mixed and isotopically uniform, non-uniform stomatal closure, promoting different e...

seeds of 200 accessions of alfalfa (medicago sativa l.) were provided from iraniannatural resource gene bank and were sown as drilled plot using alpha designs/unreplicatedwith 2 repeated entries within all of 10 blocks under dry land farming system in agriculturalresearch center of hamadan, iran during 2009 to 2010. the data were collected and analyzedfor plant height, stem number, leaf stem ra...

The in vitro zinnia (Zinnia elegans) mesophyll cell system, in which leaf mesophyll cells are induced to transdifferentiate into tracheary elements with high synchrony, has become an established model for studying xylogenesis. The architecture of the stem vascular system of zinnia cv Envy contains three anatomically distinct vascular bundles at different stages of development. Juvenile vascular...

objective: evaluation activity was conducted using three spearmint genotypes (wg-spm-engl, spm-fran and spm-eas) and one standard check (wgsm-03) at wondo genet, awassa, debre zeit and allagae during 2012 and 2013 for two years. methods: the treatments were arranged in randomized complete block design with four replications. data on leaf to stem ratio, leaf yield/ha, essential oil content and e...
