V.28

(communications, standard)
An ITU-T physical interface standard for serial data communications equipment, formally titled "Electrical Characteristics for Unbalanced Double-Current Interchange Circuits". The combination of V.28 and V.24 is equivalent to the EIA's RS-232 and uses the same 25-pin connectors.

V.28

An ITU standard (1972) that defines the functions of all circuits for the RS-232 interface. In the U.S., EIA-232 incorporates the electrical signal definitions of V.28, the control signals of V.25 and the connector and pin assignments defined in ISO 2110.

We also examined the expression of various chemokine receptors by RPE cells using multiplex PCR kits (Human chemokine receptor CCR kit-1 and kit-2, Maxin Biotech Inc., San Francisco, CA, USA) designed to detect the expression of human CCR1, CCR2, CCR3, CCR4, CCR5, CCR8, V28, CCR11, CCR6, CCR7, and GAPDH genes by identifying PCR products of 500 bp (GAPDH), 363 bp (CCR1), 318bp (CCR3), 287bp (CCR4), 246bp (CCR5), 163bp (CCR2), 428 bp (CCR8), 349bp (V28), 302bp (CCR11), 259bp (CCR6), and 214bp (CCR7).
Las variables relativas a la carga o presion fiscal nacional (v6) y al gasto social (v28), aunque no poseen contribuciones tan elevadas como las variables anteriores en este eje, alcanzan en el sus contribuciones mas altas y se situan en la parte superior al eje, reflejando asociaciones importantes con las variables proxy del efecto de las pensiones sobre la reduccion de la desigualdad y pobreza.
