Longitudinal changes in nonfunctioning pituitaryneuroendocrine tumors in children receiving growthhormone therapy: A comparison with untreated patients

Yasemin F, Bahar · Kürşat, Çetin · Zeynep, Donbaloğlu · Mesut, Parlak · y 1 más

Background: Growth hormone deficiency (GHD) may result from structural abnormalities or space-occupying lesions of the pituitary gland; therefore, pituitary magnetic resonance imaging (MRI) is routinely performed as part of the etiological assessment. The reported prevalence of incidentally detected pituitary neuroendo...

Discrete energy consistency for dynamic finite-strain frictional contact models with inelastic transformation

Barboteu, Mikaël · Bonaldi, Francesco · Dumont, Serge · Mansour, Rawane · y 1 más

This paper presents a thermodynamically consistent framework for the numerical treatment of finite-strain contact problems involving frictional interaction and inelastic material transformations, with particular reference to plastic or superelastic materials. The formulation combines large-deformation continuum mechani...

Global stability in an age-structured SIRS malaria transmission model

Séraphin Djaoué · Irépran Damakoa · Antoine Perasso · Quentin Richard

This paper proposes and analyzes a malaria transmission model structured by the chronological age of the human host population. The model couples an age-structured SIRS system for humans, incorporating waning immunity, with an SI system for mosquitoes under mass-action transmissions. Using integrated semigroup theory a...

Partial weight one modularity for Galois representations associated to mod p Hilbert modular forms

Hanneke Wiersema

Let $p$ be an odd prime. Let $ρ: G_F \to \mathrm{GL}_2(\overline{\mathbb{F}}_p)$ be a Galois representation of a totally real field $F$. For a small partial weight one weight $(k,0)$, we prove that modularity of $ρ$ can be characterised using $p$-adic Hodge theory, as conjectured by Diamond and Sasaki. We show that if...

Combinatorial metabolic engineering of Mycobacterium neoaurum LY-2 for efficient androstenedione production from phytosterols

Xu, Liyang · Peng, Chuxian · Pan, Wenjing · Tong, Yingjia · y 3 más

Androstenedione (AD) is an important precursor for the synthesis of corticosteroids, sex hormones, and other high-value steroid pharmaceuticals. Microbial conversion of phytosterols provides a sustainable route for AD production, but current production levels remain insufficient for practical industrial application. In...

Effect of pH and ionic strength on rheological and textural properties of fava bean protein–pea starch composite gels

Laura Melanie Ignatzy · Melanie Marx · Susanne Gola · Isabel Sara Muranyi · y 2 más

Understanding the structure formation of protein–starch composite gels is essential for tailoring texture and functionality in plant-based systems. This study systematically investigated fava bean protein–pea starch gels to determine how starch-to-protein ratio, pH (5 and 7), and ionic strength (0.0, 0.3, and 0.5 M NaC...

Ribosome engineering enhances genetic code expansion in Saccharomyces cerevisiae

Xiaoxu Chen · Wenlu Shen · Xianqing Chen · Fangfang Zhang · y 3 más

Genetic code expansion enables the site-specific installation of noncanonical amino acids (ncAAs) into proteins, but its limited efficiency in eukaryotes remains a major barrier to broader application. Here we establish a visual, plug-and-play screening platform to evolve 18S ribosomal DNA in Saccharomyces cerevisiae a...

Many inhibitors with defined yeast targets have limited activity against the microsporidian Nematocida parisii

Qingyuan, Huang · Guoqing, Pan · Jie, Chen · Aaron W, Reinke

Microsporidia are obligate intracellular parasites that infect diverse animals. Budding yeast has long been used to define core molecular pathways and inhibitors that target them. To test whether these compounds can target conserved pathways in the microsporidian Nematocida parisii, we assessed 15 inhibitors with defin...
