And

conj. with, together with; also, too

The AND gate is a digital logic gate that implements logical conjunction - it behaves according to the truth table to the right. A HIGH output (1) results only if both the inputs to the AND gate are HIGH (1). If neither or only one input to the AND gate is HIGH, a LOW output results.

In sickle cell anaemia, due to sickling of the red cells, the passage of the cells through the microcirculation may become obstructed leading to tissue infarction. Due to infarcts of small bones there is pain in hands and feet and it also results in digits of varying lenth,this is called hand-and-foot syndrome.

<logic> (Or "conjunction") The Boolean function which is true only if all its arguments are true. The truth table for the two argument AND function is:
A | B | A AND B --+---+--------- F | F | F F | T | F T | F | F T | T | T
AND is often written as an inverted "V" in texts on logic. In the C programming language it is represented by the && (logical and) operator.
