Ill-posedness for the two component Degasperis-Procesi equation in critical Besov space [PDF]

arXiv, 2022
In this paper, we study the Cauchy problem for the two component Degasperis-Procesi equation in critical Besov space $B^1_{\infty,1}(\mathbb R)$. By presenting a new construction of initial data, we proved the norm inflation of the corresponding solutions in $B^1_{\infty,1}(\mathbb R)$ and hence ill-posedness.

Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

Molecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

Antifungal prophylaxis in critically ill patients [PDF]

, 2008
We congratulate van Till and colleagues on their review showing that selective decontamination of the digestive tract (SDD) is more effective than single-drug prophylaxis (SAP) in reducing yeast colonisation, infection and mortality [1].

Comparison of Serum Vitamin D Status in Critically ill and Non-critically ill Children and its Relationship with Illness Severity and Clinical Outcomes: A Case–Control Study

International Journal of Medicine and Health Development
Background: The role of vitamin D in immune function is well-established in adults, but remains unclear in children. Objectives: We aimed to determine the prevalence of vitamin D deficiency in critically ill versus non-critically ill children and the ...

Remarks on the Prandtl Equation [PDF]

arXiv, 2011
In a recent result of Gerard-Varet and Dormy [5], they established ill-posedness for the Cauchy problem of the linearized Prandtl equation around non-monotic special solution which is independent of x and satisfies the heat equation. In [6] and [7], some nonlinear ill-posedness were established with this counterexample.

Evaluation of Nutrition Risk and Its Association With Mortality Risk in Severely and Critically Ill COVID‐19 Patients

JPEN - Journal of Parenteral and Enteral Nutrition, 2020
Background The nutrition status of coronavirus disease 2019 patients is unknown. This study evaluates clinical and nutrition characteristics of severely and critically ill patients infected with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2)

The microbiome and critical illness [PDF]

The Lancet Respiratory Medicine, 2016
The central role of the microbiome in critical illness is supported by a half century of experimental and clinical study. The physiological effects of critical illness and the clinical interventions of intensive care substantially alter the microbiome.

Inhibitor of DNA binding‐1 is a key regulator of cancer cell vasculogenic mimicry

Molecular Oncology, EarlyView.
Elevated expression of transcriptional regulator inhibitor of DNA binding 1 (ID1) promoted cancer cell‐mediated vasculogenic mimicry (VM) through regulation of pro‐angiogenic and pro‐cancerous genes (e.g. VE‐cadherin (CDH5), TIE2, MMP9, DKK1). Higher ID1 expression also increased metastases to the lung and the liver.
