A Drosophila Model for Clostridium difficile Toxin CDT Reveals Interactions with Multiple Effector Pathways [PDF]
Summary: Clostridium difficile infections (CDIs) cause severe and occasionally life-threatening diarrhea. Hyper-virulent strains produce CDT, a toxin that ADP-ribosylates actin monomers and inhibits actin polymerization.

Precise Implementation of CDTA
The Current Differencing Transconductance Amplifier (CDTA) is a popular active building block for analog signal processing. Since it is not available as a commercial IC, most of the CDTA applications are verified only via simulations or the CDTA is ...

0.5 V, Low-Power Bulk-Driven Current Differencing Transconductance Amplifier [PDF]
This paper presents a novel low-power low-voltage current differencing transconductance amplifier (CDTA). To achieve a low-voltage low-power CDTA, the BD-MOST (bulk-driven MOS transistor) technique operating in a subthreshold region is used. The proposed

Crystallization-driven template autocatalysis induces mirror symmetry breaking and amplification [PDF]
A plausible hypothesis for the origin of biological homochirality invokes chiral symmetry breaking, transfer, and amplification driven by autocatalysis. Here we experimentally demonstrate that crystallization-driven template autocatalysis (CDTA) induces ...

New current-mode quadrature oscillators using CDTA
This letter proposes two new realizations of current-mode (CM)quadrature oscillator (QO) using CDTA (Current Differencing Transconductance Amplifier) as the active element. The proposed circuits are canonic in component count and use two grounded capacitors which is ideal from IC fabrication point of view.

Distinct Roles for CdtA and CdtC during Intoxication by Cytolethal Distending Toxins. [PDF]
Cytolethal distending toxins (CDTs) are heterotrimeric protein exotoxins produced by a diverse array of Gram-negative pathogens. The enzymatic subunit, CdtB, possesses DNase and phosphatidylinositol 3-4-5 trisphosphate phosphatase activities that induce ...

NBTI Fast Electrical Characterization in pMOSFET Devices
To measure the entire characteristic of p-MOSFET, we have implemented the fast Ids-Vgs technique. The latter is used to study NBTI phenomenon with measure-stress-measure method, for electric field 5MV/cm < Eox < 7.5MV/cm, and temperatures 27°C < Ts ...
