BPD was followed by improved cardiovascular profile and a lower pro-inflammatory state. BPD did not produce significant malnutrition, anemia or renal stone disease.

The production of 5'-IMP and 5'-GMP by enzymatic conversion from RNA using a continuous two packed-bed reactor was investigated. 5'-Phosphodiesterase (5'PD) and 5'-adenylate deaminase (5'AD) were immobilized in an acrylic resin to produce derivatives with about 15 U/g of support. The kinetic properties of the enzymes were described by Michaelis-Menten models: no significant differences were found in the K m value of the free and immobilized 5'AD (60 and 20 μM, respectively), whereas for 5'PD the K m value was one order of magnitude higher for the immobilized enzyme (4.85 mg RNA/ml), probably due to diffusional limitations. Both enzymes remained stable after 8 h of use in a continuous packed-bed reactor whereas the half lives of the free enzymes were 193 min and 240 min at 40°C and 70°C for 5'AD and 5'PD, respectively. A procedure is proposed for the design of a continuous two packed-bed column process.

Surgery is usually the only solution to modify the evolution of morbid obesity and resolve the associated co-morbidities. There is very little written regarding malabsorptive surgery and transplantation. A 48-year-old male with hypertension, hyperuricemia and obesity underwent renal transplantation in 1994 for renal amyloidosis. He was maintained on oral immunosuppressive cyclosporine. The patient developed uncontrollable hypertension, hyperlipemia, hyperglycemia and increasing weight to a BMI of 44. Thus, in December 2004, he underwent biliopancreatic diversion (BPD). After 18 months follow-up, he has lost 85% of his excess weight, and his hypertension, hyperglycemia and hyperlipemia are markedly improved. Renal function was not modified, nor were the levels of cyclosporine. He has had no complications derived from the BPD, and has a better quality of life.
