Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Numbers with n different prime factors in their prime factorization

Gulf Journal of Mathematics, 2014
In this note we give a simple proof of the well-known result that the numbers with a fixed number of different prime factors in their prime factorization have density zero.

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

On Prime Ideals in Rings Satisfying Certain Functional Identities

Axioms
In this note, we will examine the relationship between a generalized derivation ϝ associated with a derivation ∂ that satisfies specific algebraic identities and the behavior of a factor ring S/P, where P is a prime ideal of any ring S.

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

FEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

Influence of temperature perturbation on moisture dynamics

Journal of Physics Communications
We analyzed the perturbation effect of temperature on the moisture content in the atmosphere [ 1 ], considering the saturation phenomenon. The air parcels of a saturated atmosphere are made of dry air, vapor, cloud, and rain water that flow on a rotating

Factor Rings with Algebraic Identities via Generalized Derivations

Axioms
The current article focuses on studying the behavior of a ring ℜ/Π when ℜ admits generalized derivations Ψ and Ω with associated derivations ϕ and δ, respectively. These derivations satisfy specific differential identities involving Π, where Π is a prime

A conceptual proposal on the undecidability of the distribution law of prime numbers and theoretical consequences

Ratio Mathematica, 2019
Within the conceptual framework of number theory, we consider prime numbers and the classic still unsolved problem to find a complete law of their distribution.
