Additive Functionals and Excessive Functions
During the past five or six years there has been much work done on the problem of representing excessive functions as the potentials of additive functionals. This is a natural generalization to Markov processes of the classical theorem of Riesz dealing with the representation of non-negative superharmonic functions as the potentials of measures.

Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Subclasses of Analytic Functions Defined by Carlson - Shaffer Linear Operator
[[abstract]]We introduce the subclass LT (a, c; , ) of analytic functions with negative coefficients defined by the linear operator L(a, c)f(z) which introduced and studied by Carlson and Shaffer [4].

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Phosphoinositides and inositol phosphates as molecular glues
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Estimates for the Initial Coefficients of Bi-univalent Functions
[[abstract]]A bi-univalent function is a univalent function defined on the unit disk for which the inverse function has a univalent extension to the unit disk. The paper of H. M. Srivastava, A. K. Mishra and P.

Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Rank-one properties for BV functions [PDF]
openIn this thesis we insvestigate some recent alternative proofs to the celebrated Alberti’s Rank-one Theorem for BV functions, in the standard Euclidean setting and in the context of Carnot groups.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
