A high dynam.c range and low.noise Cm.S(com.lem.ntary m.tal-oxide-sem.conductor transistor)front-end interface integrated circuit(IC) w.th m.lti-channel detection is presented in this paper. Tw. different current detection channels, com.osed of a trans-im.edance am.lifier(TIA) and an integrator-differentiator TIA, are used to boost the current detection range. A capacitance-coupled instrum.nt am.lifier(CCIA) is also included to realize high precision voltage detection. A fourth-order sigm.-delta m.dulator using a second-order loop filter and a second-order noise shaping integral quantizer is adopted to realize effective num.er of bits above 16 bits. The presented interface IC is im.lem.nted in 0.18-μm.Cm.S process w.th supply voltage of 3.3 V, and a proto-type electrochem.cal sensor platform.w.th m.niaturized sensor array is developed to verify the functionality of the interface IC. m.asurem.nt results indicate that the designed interface IC achieves 157.8 d B current detection dynam.c range, and the m.asured input-referred current noise and voltage noise floor are 1.04 p A and 58.4 n V w.thin 10 k.Hz integration bandw.dths,respectively.

Hum.n m.oblast Genom. Therapy (Hm.T) is a platform.technology of cell transplantation, nuclear transfer, and tissue engineering. Unlik. stem.cells, m.oblasts are differentiated, im.ature cells destined to becom. m.scles. m.oblasts cultured from.satellite cells of adult m.scle biopsies survive, develop, and function to revitalize degenerative m.scles upon transplantation. Injection injury activates regeneration of host m.ofibers that fuse w.th the engrafted m.oblasts, sharing their nuclei in a com.on gene pool of the syncytium. Thus, through nuclear transfer and com.lem.ntation, the norm.l hum.n genom. can be transferred into m.scles of patients w.th genetic disorders to achieve phenotype repair or disease prevention. m.oblasts are safe and efficient gene transfer vehicles endogenous to m.scles that constitute 50% of body w.ight. Results of over 280 Hm.T procedures on Duchenne m.scular Dystrophy (Dm.) subjects in the past 15 years dem.nstrated absolute safety. m.oblast-injected Dm. m.scles show.d im.roved histology. Strength increase at 18 m.nths post-operatively averaged 123%. In another application of Hm.T on ischem.c cardiom.opathy, the first hum.n m.oblast transfer into porcine m.ocardium.revealed that it w.s safe and effective. Clinical trials on approxim.tely 220 severe cardiom.opathy patients in 15 countries show.d a m.rtality. m.st subjects received autologous cells im.lanted on the epicardial surface during coronory artery bypass graft, or injected on the endom.ocardial surface percutaneously through guiding catheters. Significant increases in left ventricular ejection fraction, w.ll thick.ess, and w.ll m.tion have been reported, w.th reduction in perfusion defective areas, angina, and shortness of breath. As a new.m.dality of treatm.nt for disease in the sk.letal m.scle or m.ocardium. Hm.T em.rged as safe and effective. Large random.zed m.lti-center trials are under w.y to confirm.these prelim.nary results. The future of Hm.T is bright and exciting.
