FEBS Open Bio, EarlyView.Research is strongest when conducted alongside patients, not just about them. Patient research organizations help integrate patient perspectives into research priorities, study design, and scientific meetings, leading to meaningful patient outcomes and development of relevant therapies.

FEBS Open Bio, EarlyView.In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Oscillations Of Neutral Differential Equations
, 1991 Abstract A neutral delay differential equation is a differential equation in which the highest-order derivative of the unknown function appears in the equation both with and without delays.

Recent insights into the molecular mechanism of ubiquinol oxidation by cytochrome bc1
FEBS Open Bio, EarlyView.The review reflects on the mechanism of the catalytic reaction in cytochrome bc1: the electron bifurcation that involves the separation of two electrons derived from the quinol oxidation to opposite sides of the enzyme across the membrane. This review summarizes the long‐standing effort to understand the mechanism of quinol oxidation catalyzed by ...

FEBS Open Bio, EarlyView.TGF‐β1 stimulation downregulates lysosomal channel TRPML1 in pulmonary fibroblasts. The TRPML1 agonist ML‐SA5 suppressed fibroblast‐to‐myofibroblast activation and collagen production. Mechanistically, ML‐SA5 inhibited mTOR phosphorylation, restored autophagic flux, and its effects were enhanced by rapamycin (mTOR inhibitor) and reversed by MHY1485 ...

Oscillation criteria for a linear neutral differential equation
Journal of Mathematical Analysis and Applications, 2003 Consider the neutral differential equation of the form \[ \dot{x}( t) -a( t) \dot{x}( g( t) ) +b( t) x(h( t) )=0, \] with \(0\leq a( t)

Ethical Foreground and Background in Adult Educator Work
New Directions for Adult and Continuing Education, EarlyView.ABSTRACT Adult educators work in a complex ethical environment. The very act of contributing to the learning of another is fraught with moral overtones. In this paper we consider the ethical dimensions of adult educator practice by distinguishing the ethical features of the context or ‘background’ of practice from the ethical capabilities and decision ...

eriodicity and stability in neutral nonlinear differential equations with functional delay
Electronic Journal of Differential Equations, 2005 We study the existence and uniqueness of periodic solutions and the stability of the zero solution of the nonlinear neutral differential equation $$ frac{d}{dt}x(t) = -a(t)x(t)+ frac{d}{dt}Q(t, x(t-g(t))) +G(t,x(t), x(t-g(t))).

Gravity‐Dependent Modulation of Downbeat Nystagmus: Insights From Velocity‐Storage Dysfunction
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.
