Reaching Agreement in Competitive Microbial Systems [PDF]

open access: yesarXiv, 2021
We study distributed agreement in microbial distributed systems under stochastic population dynamics and competitive interactions. Motivated by recent applications in synthetic biology, we examine how the presence and absence of direct competition among microbial species influences their ability to reach majority consensus. In this problem, two species

New Conditional Symmetries and Exact Solutions of the Diffusive Two-Component Lotka–Volterra System

open access: yesMathematics, 2021
The diffusive Lotka–Volterra system arising in an enormous number of mathematical models in biology, physics, ecology, chemistry and society is under study. New Q-conditional (nonclassical) symmetries are derived and applied to search for exact solutions

Kin Selection in the RNA World

open access: yesLife, 2017
Various steps in the RNA world required cooperation. Why did life’s first inhabitants, from polymerases to synthetases, cooperate? We develop kin selection models of the RNA world to answer these questions.

LAG3’s Enigmatic Mechanism of Action

open access: yesFrontiers in Immunology, 2021
LAG3 is an important immune checkpoint with relevance in cancer, infectious disease and autoimmunity. However, despite LAG3’s role in immune exhaustion and the great potential of LAG3 inhibition as treatment, much remains unknown about its biology ...

Direct competition results from strong competiton for limited resource [PDF]

open access: yesJournal of Mathematical Biology (2013) 0303-6812, 2012
We study a model of competition for resource through a chemostat-type model where species consume the common resource that is constantly supplied. We assume that the species and resources are characterized by a continuous trait. As already proved, this model, although more complicated than the usual Lotka-Volterra direct competition model, describes ...

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

Ethical framework on risk governance of synthetic biology

open access: yesJournal of Biosafety and Biosecurity, 2023
Synthetic biology is an emerging multidisciplinary field that aims to design and construct new biological systems not found in nature. Whereas synthetic biology may yield tremendous benefits, it may also pose substantial risks to human health and the ...

Scientific reasoning skills (SRS): Predictor to the student’s problem-solving in the biology classroom?

open access: yesBiosfer, 2021
Scientific reasoning and problem-solving have become primary interests in 21st-century education. These skills have an essential role in preparing students to face global competition.

Predicting coexistence of plants subject to a tolerance-competition trade-off [PDF]

open access: yes, 2013
Ecological trade-offs between species are often invoked to explain species coexistence in ecological communities. However, few mathematical models have been proposed for which coexistence conditions can be characterized explicitly in terms of a trade-off. Here we present a model of a plant community which allows such a characterization.

Functional variation among LPMOs revealed by the inhibitory effects of cyanide and buffer ions

open access: yesFEBS Letters, EarlyView.
This study addresses the inhibition of lytic polysaccharide monooxygenases (LPMOs) by cyanide and explains how and why the magnitude of observed inhibitory effects depends on the way LPMO reactions are setup and on the type of LPMO. Enzymes known as lytic polysaccharide monooxygenases (LPMOs) are mono‐copper polysaccharide‐degrading peroxygenases that ...
