Question: What type of films are both My Flesh and Blood and Exploratorium?

<P0-S0> Cis AB is a rare mutation in the ABO gene which complicates the basic inheritance pattern and blood-transfusion compatibility matching for ABO blood typing. <P0-S1>  There are different DNA mutations of either type A or Type B alleles that change several amino acids in enzyme transferase A or B, homologous enzymes differing in only four of 354 amino acids (R176G, G235S, L266M, and G268A). <P0-S2>  A single change in ABO gene DNA could reverse type B to type A and then, a new hybrid enzyme will produce both weak B and A2 (in serum test, A2B and A2B3)). <P0-S3>  The most common mutation is an A105 allele variation in exon 7 nucleotide position G803C changing Glycine (type A) to Alanine (type B). <P0-S4>  There are another 8 alleles reported in BGMUT, the most discovered reciently in China and Taiwan. <P0-S5>  In the cis-AB genotype, both antigens are expressed, like in a standard (trans) AB genotype. <P0-S6>  In a traditional AB phenotype, A and B antigenes are inherited separately from the father and mother while a cis-AB allele comes from one parent only. <P0-S7>  In a serum test, cis-AB tests almost the same as a traditional AB, but people with this rare type have problems with blood transfusions. <P0-S8>  Some of them need components like washed red blood cells or autotransfusion of serum and blood. <SEP> <P1-S0> Exploratorium is a 1974 American short documentary film about the Exploratorium science museum in San Francisco, produced by Jon Boorstin. <P1-S1>  The film explores the museum through imagery and sound, without voice-over. <P1-S2>  It was nominated for an Academy Award for Best Documentary Short. <SEP> <P2-S0> My Flesh and Blood is a 2003 documentary film by Jonathan Karsh chronicling a year in the life of the Tom family. <P2-S1>  The Tom family is notable as the mother, Susan Tom, adopted eleven children, most of whom had serious disabilities or diseases. <P2-S2>  It was nominated for and won several awards, including the Audience Award and the Director's Award at the Sundance Film Festival. <SEP> <P3-S0> The Ashby technique is a method for determining the volume and life span of red blood cells in humans, first published by Dr. Winifred Ashby in 1919. <P3-S1>  The technique involves injection of compatible donor red blood cells of a different blood group into a recipient, followed by blood testing periodically afterwards. <P3-S2>  Differential agglutination of the red cells is then used to determine the number of remaining donor cells, allowing the survival rate to be determined. <P3-S3>  It does not involve radioisotope technology, and was the first technique to successfully establish the correct red blood cell life span. <P3-S4>  In particular, Type O blood is first transfused into Type A or B subjects. <P3-S5>  In subsequent blood samples, the patient's own A and B blood cells are removed by agglutination with either anti-A or anti-B serum. <P3-S6>  The number of remaining nonagglutinated Type O cells as a function of time defines the survival rate of blood cells. <P3-S7>  This technique was used extensively during World War II and shortly after but has more recently been replaced by techniques that label one's own blood, due of the dangers of using donor blood.
