Blood type O Rh-hypo-immunogenic pluripotent cells
The invention discloses for the first time pluripotent cells, including hypoimmune pluripotent ABO blood type O Rhesus Factor negative (HIPO−) cells, that evade rejection by the host allogeneic immune system and avoid blood antigen type rejection. The HIPO− cells comprise reduced HLA-I and HLA-II expression, increased CD47 expression, and a universal blood group O Rh− (“O−”) blood type. The universal blood type is achieved by eliminating ABO blood group A and B antigents as well as eliminating Rh factor expression, or by starting with an O− parent cell line. These new, novel HIPO− cells evade host immune rejection because they have an impaired antigen presentation capacity, protection from innate immune clearance, and lack blood group rejection. The cells of the invention also include O− pluripotent stem cells (iPSCO−) and O− embryonic stem cells (ESCO−). The invention further provides universally acceptable “off”-the-shelf pluripotent cells and derivatives thereof for generating or regenerating specific tissues and organs. |

Production of low-alcohol or alcohol-free beer with Pichia kluyveri yeast strains
It has unexpectedly been found that a low alcohol or alcohol-free beverage, with a flavor profile very close to a beer of at least 4% (vol/vol) alcohol, can be produced by using Pichia kluyveri yeast strains.

Method for the preparation use of an alkoxy-functional organohydrogensiloxane oligomer using purified starting materials an duse of the oligomer
A method for the preparation of an alkoxy-functional hydrogensiloxane oligomer includes reacting a polyorganohydrogensiloxane oligomer and an aliphatically unsaturated alkoxysilane in the presence of a hydrosilylation reaction and a promoter. The resulting reaction product is distilled, treated with a treating agent, and distilled again to produce the alkoxy-functional organohydrogensiloxane oligomer. The alkoxy-functional hydrogensiloxane oligomer can be reacted with polyorganosiloxane having an aliphatically unsaturated monovalent hydrocarbon group to form a polyalkoxy-functional polyorganosiloxane. The polyalkoxy-functional polyorganosiloxane can be formulated in condensation reaction curable compositions. |
