Asymptotic behavior of a free boundary problem for the growth of multi-layer tumors in necrotic phase [PDF]

, 2018
In this paper we study a free boundary problem for the growth of multi-layer tumors in necrotic phase. The tumor region is strip-like and divided into necrotic region and proliferating region with two free boundaries. The upper free boundary is tumor surface and governed by a Stefan condition.

Disrupted Maturation of the Microbiota and Metabolome among Extremely Preterm Infants with Postnatal Growth Failure [PDF]

, 2019
Growth failure during infancy is a major global problem that has adverse effects on long-term health and neurodevelopment. Preterm infants are disproportionately affected by growth failure and its effects.

Loss of murine Paneth cell function alters the immature intestinal microbiome and mimics changes seen in neonatal necrotizing enterocolitis [PDF]

, 2018
Necrotizing enterocolitis (NEC) remains the leading cause of gastrointestinal morbidity and mortality in premature infants. Human and animal studies suggest a role for Paneth cells in NEC pathogenesis.

Assessment of the state of hemodynamic in the area of superior mesenteric artery in newborns with necrotizing enterocolitis

Неонатологія, хірургія та перинатальна медицина, 2019
The feasibility and effectiveness of superior mesenteric artery Doppler ultrasonography in the diagnosis of necrotizing enterocolitis and other gastrointestinal pathologies in newborns were evaluated in this article. It was found that with in necrotizing

Tumor growth with a necrotic core as an obstacle problem in pressure [PDF]

arXiv, 2023
Motivated by the incompressible limit of a cell density model, we propose a free boundary tumor growth model where the pressure satisfies an obstacle problem on an evolving domain $\Omega(t)$, and the coincidence set $\Lambda(t)$ captures the emerging necrotic core.

Plants, plant‐derived compounds, probiotics, and postbiotics as green agents to fight against poultry coccidiosis: A review

Animal Research and One Health, EarlyView.
Therapeutic effect of natural products on chicken coccidiosis. Abstract The intestinal tract is the main place for animals to digest food and absorb nutrients, which also serves as the first line of defense against pathogens that invade the internal environment.

Association of intestinal alkaline phosphatase with necrotizing enterocolitis among premature infants [PDF]

, 2019
Importance: Necrotizing enterocolitis (NEC) in preterm infants is an often-fatal gastrointestinal tract emergency. A robust NEC biomarker that is not confounded by sepsis could improve bedside management, lead to lower morbidity and mortality, and permit

Dichotomous development of the gut microbiome in preterm infants. [PDF]

, 2018
BackgroundPreterm infants are at risk of developing intestinal dysbiosis with an increased proportion of Gammaproteobacteria. In this study, we sought the clinical determinants of the relative abundance of feces-associated Gammaproteobacteria in very low

Patterns of volatile organic compounds in excrements of preterm neonates

European Journal of Clinical Investigation, Volume 53, Issue 1, January 2023., 2023
Abstract Background As neonates are susceptible for many diseases, establishing noninvasive diagnostic methods is desirable. We hypothesized that volatile organic compounds (VOCs) could be successfully measured in diaper samples. Methods We performed a feasibility study to investigate whether ambient air‐independent headspace measurements of the VOC ...

A multiphase Cahn-Hilliard-Darcy model for tumour growth with necrosis [PDF]

Math. Models Methods Appl. Sci. 28 (2018) 525--577, 2017
We derive a Cahn-Hilliard-Darcy model to describe multiphase tumour growth taking interactions with multiple chemical species into account as well as the simultaneous occurrence of proliferating, quiescent and necrotic regions. Via a coupling of the Cahn-Hilliard-Darcy equations to a system of reaction-diffusion equations a multitude of phenomena such ...
