SPD

(Serial Presence Detect) The method used by DIMM memory modules to communicate their capacity and features to the computer. Data such as manufacturer, size, speed, voltage and row and column addresses are stored in an EEPROM chip on the module. Two pins are used to transmit the data in serial, in contrast to the earlier parallel method (PPD), in which each pin represented one bit. See PPD.

[52] showed that the expression of HOXC13 increased whereas HOXD13 expression decreased as bone marrow-derived MSCs differentiated into osteoblasts during osteogenesis.
Among HOXD family members, HOXD10, HOXD11, HOXD13, and HOXD9 showed increased expression compared to the others (Figure 6(c)).

Missense mutations in R31 have been found in the human homeobox genes PITX2, MSXI, MSX2, LMX1B, and HOXD13 and are associated with 5 different developmental diseases: iridogoniodysgenesis syndrome, tooth agenesis, enlarged parietal foramina, nail-patella syndrome, and several digital anomalies, respectively (18, 19).
