Production of antibacterial compounds by a Steely hybrid polyketide synthase in Dictyostelium
FEBS Open Bio, EarlyView.By selecting appropriate production species under optimised culture conditions, new chlorinated dibenzofuran compounds, which previously could not be analysed in sufficient quantities, were identified from cellular slime mould fruiting bodies. The strong antibacterial activity exhibited by these compounds suggests a link to the ecological function of ...

Which Quantum Theory Must be Reconciled with Gravity? (And What Does it Mean for Black Holes?)
Universe, 2016 We consider the nature of quantum properties in non-relativistic quantum mechanics (QM) and relativistic quantum field theories, and examine the connection between formal quantization schemes and intuitive notions of wave-particle duality.

A general model for analysis of linear and hyperbolic enzyme inhibition mechanisms
FEBS Open Bio, EarlyView.We developed a general enzyme kinetic model that integrates these six basic inhibition mechanism onto a single one. From this model, we deduced a general enzyme kinetic equation that through modulation of simple parameters, γ (the relative inhibitor affinity for two binding sites) and β (the reactivity of the enzyme–substrate–inhibitor complex), is ...

Molecular determinants of signal transduction in tropomyosin receptor kinases
FEBS Open Bio, EarlyView.Tropomyosin receptor kinases control critical neuronal functions, but how do the same receptors produce diverse cellular responses? This review explores the structural mechanisms behind Trk signaling diversity, focusing on allosteric modulation and ligand bias.

Elementary Particles and the Causet Approach to Discrete Quantum Gravity
, 2014 In a previous paper, the author introduced a covariant causet ($c$-causet) approach to discrete quantum gravity. A $c$-causet is a finite partially ordered set that is invariant under labeling.

Advanced Chinese Medicine, EarlyView.Abstract The gut microbiota plays a pivotal role in maintaining host metabolic homeostasis and overall physiological functions. Shenling Baizhu San (SLBZS), a time‐honored classical prescription for tonifying Qi, strengthening the spleen, removing dampness, and arresting diarrhea, has shown broad clinical efficacy in digestive disorders.

Annals of Clinical and Translational Neurology, EarlyView.Longitudinal changes in salivary biomarkers in Parkinson’s disease (PD) from early (T0) to 4‐year follow‐up (T1), quantified by ELISA: oligomeric and total α‐synuclein, total and phosphorylated tau, MAP1LC3B (autophagy), and TNFa (inflammation). Blue arrows indicate direction of change at T1 vs T0 (up = increase; down = decrease).
