Differential conductance as a promising approach for rapid DNA sequencing with nanopore-embedded electrodes

We propose an approach for nanopore-based DNA sequencing using characteristic transverse differential conductance. Molecular dynamics and electron transport simulations show that thetransverse differential conductance during the translocation of DNA through the nanopore isdistinguishable enough for the detection of the base sequence and can withstand electrical noisecaused by DNA structure fluctuation. Our findings demonstrate several advantages of the transverseconductance approach, which may lead to important applications in rapid genome sequencing

Data_Sheet_1_Nxhl Controls Angiogenesis by Targeting VE-PTP Through Interaction With Nucleolin.docx

Precise regulation of angiogenesis is required for organ development, wound repair, and tumor progression. Here, we identified a novel gene, nxhl (New XingHuo light), that is conserved in vertebrates and that plays a crucial role in vascular integrity and angiogenesis. Bioinformatic analysis uncovered its essential roles in development based on co-expression with several key developmental genes. Knockdown of nxhl in zebrafish causes global and pericardial edema, loss of blood circulation, and vascular defects characterized by both reduced vascularization in intersegmental vessels and decreased sprouting in the caudal vein plexus. The nxhl gene also affects human endothelial cell behavior in vitro. We found that nxhl functions in part by targeting VE-PTP through interaction with NCL (nucleolin). Loss of ptprb (a VE-PTP ortholo) in zebrafish resulted in defects similar to nxhl knockdown. Moreover, nxhl deficiency attenuates tumor invasion and proteins (including VE-PTP and NCL) associated with angiogenesis and EMT. These findings illustrate that nxhl can regulate angiogenesis via a novel nxhl–NCL–VE-PTP axis, providing a new therapeutic target for modulating vascular formation and function, especially for cancer treatment.</p

Improved hydrogen photoproduction regulated by carbonylcyanide m-chlorophenylhrazone from marine green alga Platymonas subcordiformis grown in CO2-supplemented air bubble column bioreactor

To develop an integrated process of CO2- fixation and H-2 photoproduction by marine green microalga Platymonas subcordiformis, the impact of algal cells grown in CO2- supplemented air bubble column bioreactor was investigated on H-2 photoproduction regulated by carbonylcyanide m- chlorophenylhrazone. Highest cell growth ( 3.85 9 10(6) cells ml(-1)), starch content ( 0.25 +/- 0.08 mg per 10(6) cells) and hydrogen production ( 50 +/- 3 ml1(-1)) were achieved at 3% CO2- supplemented culture, which are respectively 1.4, 2.1, 1.5- fold of the air-supplemented culture. Improved H-2 production correlated well with the increase in starch accumulation. In this process, the algal cells have been recycled for stable H-2 production of 40 - 50 ml l(-1) over five cycles
