Activation of the Pacidamycin PacL Adenylation Domain by MbtH-like Proteins [PDF]
Biochemistry, 2010 Nonribosomal peptide synthetase (NRPS) assembly lines are major avenues for the biosynthesis of a vast array of peptidyl natural products. Several hundred bacterial NRPS gene clusters contain a small (∼70-residue) protein belonging to the MbtH family for which no function has been defined.

The resistance-compliance relationship at low pulmonary resistance: Integrating pulmonary wedge pressure into right ventricular load assessment. [PDF]
Physiol RepAbstract The inverse hyperbolic relationship between pulmonary vascular resistance (PVR) and pulmonary arterial compliance (PAC) is a well‐established marker of right ventricular (RV) afterload. Pulmonary capillary wedge pressure (PCWP) is a known modifier of this relationship; however, its impact across pulmonary hypertension (PH) subgroups has not ...

Functional integral for non-Lagrangian systems [PDF]
, 2010 A novel functional integral formulation of quantum mechanics for non-Lagrangian systems is presented. The new approach, which we call "stringy quantization," is based solely on classical equations of motion and is free of any ambiguity arising from ...
