Early Histocompatibility: Color the Mechanism Green and Red
نویسندگان
چکیده
Allorecognition in Hydractinia, a cnidarian, is governed by two different, highly polymorphic genes encoding transmembrane proteins. Using a fluorescent cell read-out system, a new study now shows that the basis for specificity involves homophilic interactions between extracellular domains.

A Fuzzy Based Three Color Meter/Marker for Diffserv Networks (RESEARCH NOTE)
Differentiated Services (Diffserv) which was proposed by Internet Engineering Task Force (IETF), is a scalable and robust model for providing the end-to-end QoS. In the Diffserv networks, metering mechanisms are used to measure traffic stream. The single rate Three Color Meter (srTCM) [1],which was proposed by IETF, meters an IP packet stream and marks its packets either green, yellow, or red....
متن کاملCOMPARATIVE STUDIES OF SOLVATOCHROMISM BEHAVIOUR OF COPPER(I1) AND NICKEL(I1) SCHIFF BASE COMPLEXES
A series of Schiff Bases of Ni(II) and Cu(II) using acetylacetone (acac), salicylaldehyde (sal), ethylenediamine (en), and o-phenylendiarnine (dabe) were prepared and characterized. The electronic spectra of some copper chelates in various organic solvents depend strongly on the solvent used and the d-d band of Cu(II) shifts to red with the increase of the Donor Number (DN) of solvent. The ...
متن کاملPreference of Broiler Chickens for Feed Color
Studying broiler preference to feed color is important for improving comfort and welfare of broilers and it may be beneficial for improving performance. The aim of the first experiment was to examine day-old chick's preference in different light colors to different feed colors. One hundred and sixty Ross 308 newly hatched broilers, never exposed to feed, were allocated into pens illuminated ...
متن کاملGreen Dyeing of Silk Fabrics in the Presence of Pomegranate Extract as Natural Mordant
An ecological approach has been obtained by using natural dyes and mordant for dyeing process. Silk fabrics dyed using natural mordants: powder of sour pomegranate and sweet pomegranate and mixture them. A beautiful red color were obtained by using theses mordants. The color of dyed silk fabrics was investigated in CIE Lab L, a and b and K/S values. Finally, all dyed fabrics were tested for was...
متن کاملThe spatial tuning of color and luminance peripheral vision measured with notch filtered noise masking
We have measured the spatial bandwidths of the bandpass red-green chromatic and luminance mechanisms at four locations in the nasal visual field (0, 10, 20 and 30 degrees) using a method of notch filtered noise masking which effectively removes the artifact of off-frequency looking for our stimuli. Detection thresholds were measured for luminance or isoluminant red-green Gaussian enveloped test...
