Differential impact of wildfire and rice straw ash on the skin microbiota of Rana dybowskii adults and tadpoles.

Global warming has intensified severe weather conditions and increased the frequency of wildfires, posing significant threats to ecosystems. Moreover, rice straw ash, a byproduct of human agricultural activities, represents an environmental stressor that can further impact these vulnerable ecosystems. These changes particularly impact sensitive species and microorganisms, yet limited research has explored the effects of wildfire ash and agricultural byproducts, such as rice straw ash, on amphibians.

Comparison of ranibizumab and conbercept treatment in type 1 prethreshold retinopathy of prematurity in zone II.

Purpose: The treatment with anti-VEGF for Retinopathy of prematurity (ROP) has already been widely applied in clinics even though there are still many concerns about this treatment. In this project we investigated the clinical outcomes of intra-vitreous conbercept (IVC) and ranibizumab (IVR) injection for treating type 1 prethreshold ROP in Zone II.

Methods: The data of ROP infants receiving IVR or IVC from January 2017 to March 2020 who were followed up for at least 12 months in our hospital was studied in the present retrospective study.

Pigment Epithelium-Derived Factor Binding to VEGFR-1 (Flt-1) Increases the Survival of Retinal Neurons.

Purpose: The purpose of this study was to examine possible involvement of vascular endothelial growth factor (VEGF) receptor (VEGFR)-1/Flt-1 in pigment epithelium-derived factor (PEDF)-promoted survival of retinal neurons.

Methods: Survival of growth factor-deprived retinal ganglion cells (RGCs) and R28 cells and activation of ERK-1/-2 MAP kinases were assessed in the presence of PEDF, placental growth factor (PlGF), and VEGF using cell cultures, viability assays and quantitation of ERK-1/-2 phosphorylation. VEGFR-1/Flt-1 expression was determined using quantitative PCR (qPCR) and Western blotting.

Rice straw ash and amphibian health: A deep dive into microbiota changes and potential ecological consequences.

Rice straw is burned as a result of agricultural practices and technical limitations, generating significant volumes of ash that might have environmental and ecological consequences; however, the effects on organisms have not been researched. Amphibians depend on their gut and skin microbiomes. Ash exposure may cause inflammation and changes in microbial diversity and function in frogs' skin and gut microbiota due to its chemical composition and physical presence, but the implications remain unclear.

Early prediction of clinical scores for left ventricular reverse remodeling using extreme gradient random forest, boosting, and logistic regression algorithm representations.

Objective: At present, there is no early prediction model of left ventricular reverse remodeling (LVRR) for people who are in cardiac arrest with an ejection fraction (EF) of ≤35% at first diagnosis; thus, the purpose of this article is to provide a supplement to existing research.

Materials And Methods: A total of 109 patients suffering from heart attack with an EF of ≤35% at first diagnosis were involved in this single-center research study. LVRR was defined as an absolute increase in left ventricular ejection fraction (LVEF) from ≥10% to a final value of >35%, with analysis features including demographic characteristics, diseases, biochemical data, echocardiography, and drug therapy.

The beneficial effects of exercise on glucose and lipid metabolism during statin therapy is partially mediated by changes of the intestinal flora.

Recent research has confirmed that moderate-intensity exercise affects the gut microbiome composition and improves cardiac function in an animal model after myocardial infarction (MI). However, few studies have investigated the effects of exercise on glucose and lipid metabolism in patients with coronary heart disease (CHD) receiving a statin treatment and successful percutaneous coronary intervention (PCI). Meanwhile, since statin therapy may lead to the risk of an increase in blood glucose level in CHD patients, we hypothesized that moderate-intensity exercise may be helpful for regulating glucose-lipid metabolism and stabilizing the blood glucose level in CHD patients.

Effect of anti-VEGF treatment on retinopathy of prematurity in Zone II Stage 3.

Aim: To evaluate the effect of intravitreal ranibizumab injection for retinopathy of prematurity (ROP) in Zone II Stage 3.

Methods: Data was collected for ROP patients with Zone II Stage 3 who received intravitreal ranibizumab injections between October 2014 and Janu-ary 2017 at the Department of Ophthalmology in our hospital. No prior laser or other intravitreal treatment was done.

Integrin-Linked Kinase Controls Choroidal Neovascularization by Recruitment of Endothelial Progenitor Cells.

Purpose: Vasculogenesis has been shown to contribute to the formation of choroidal neovascularization (CNV). However, the mechanism behind the recruitment of endothelial progenitor cells (EPC) to CNV is not well understood. Therefore, we were interested to know whether integrin-linked kinase (ILK) plays a role in recruiting EPC to CNV, and its possible mechanism.

Basic fibroblast growth factor contributes to a shift in the angioregulatory activity of retinal glial (Müller) cells.

Basic fibroblast growth factor (bFGF) is a pleiotropic cytokine with pro-angiogenic and neurotrophic effects. The angioregulatory role of this molecule may become especially significant in retinal neovascularization, which is a hallmark of a number of ischemic eye diseases. This study was undertaken to reveal expression characteristics of bFGF, produced by retinal glial (Müller) cells, and to determine conditions under which glial bFGF may stimulate the proliferation of retinal microvascular endothelial cells.

The axon guidance molecule Netrin-4 is expressed by Müller cells and contributes to angiogenesis in the retina.

Retinal glial (Müller) cells are involved in a wide range of developmental mechanisms, including axon guidance and angiogenesis. This study was undertaken to explore whether Netrin-4, an axonal guidance molecule, is expressed by Müller cells and promotes angiogenesis-related activities. Netrin-4 was found through all retinal layers, and its expression was demonstrated in Müller cells, retinal pigment epithelium cells and bovine retinal endothelial cells (BRECs).

Pigment epithelium-derived factor released by Müller glial cells exerts neuroprotective effects on retinal ganglion cells.

Survival of retinal ganglion cells (RGC) is compromised in several vision-threatening disorders such as ischemic and hypertensive retinopathies and glaucoma. Pigment epithelium-derived factor (PEDF) is a naturally occurring pleiotropic secreted factor in the retina. PEDF produced by retinal glial (Müller) cells is suspected to be an essential component of neuron-glial interactions especially for RGC, as it can protect this neuronal type from ischemia-induced cell death.

Hypoxia-induced upregulation of pigment epithelium-derived factor by retinal glial (Müller) cells.

Neuronal degeneration and aberrant neovascularization are common problems of ischemic retinopathies. Pigment epithelium-derived factor (PEDF), a neuroprotective protein and an inhibitor of angiogenesis, is produced by retinal glial (Müller) cells and can counterbalance elevated levels of vascular endothelial growth factor (VEGF), the expression of which is regulated primarily by hypoxia-inducible factor (HIF)-1. In an approach to mimic transient ischemia in vitro, primary Müller cells were cultured under transient and strong hypoxia (0.

Anti-angiogenic effects of the receptor tyrosine kinase inhibitor, pazopanib, on choroidal neovascularization in rats.

Neovascularization in the eye is a major cause of irreversible vision loss. The present study was undertaken to determine mechanisms through which pazopanib, a drug that targets multiple receptor tyrosine kinases such as VEGF receptors, inhibits angiogenesis and experimental choroidal neovascularization (CNV). Pazopanib inhibited VEGF expression by retinal pigment epithelium (RPE) cells and choroidal endothelial cells (CEC), decreased VEGF-induced cellular migration in a dose-dependent manner and suppressed extracellular signal-regulated kinase (ERK)-1/-2 phosphorylation.

[Value of ER, VIM, CEA and p16 detection in the diagnosis and differential diagnosis of primary endocervical and endometrial adenocarcinomas].

Objective: To evaluate the value of the detection of a 4-marker (ER, VIM, CEA and p16) panel in the differential diagnosis of primary endocervical and endometrial adenocarcinomas.

Methods: Immunohistochemical EnVison method was used to detect the expressions of ER, VIM, CEA and p16 in paraffin-embedded tissues from 31 cases of primary endocervical adenocarcinomas and 30 cases of endometrial adenocarcinomas. The specificity, sensitivity, predictive value and accuracy were compared between the 4-marker and 3-marker (ER, VIM and CEA) panels.

Focal adhesion kinase signaling pathway participates in the formation of choroidal neovascularization and regulates the proliferation and migration of choroidal microvascular endothelial cells by acting through HIF-1 and VEGF expression in RPE cells.

Choroidal neovascularization (CNV) is one of the most frequent causes of severe and progressive vision loss, while its pathogenesis is still poorly understood. Focal adhesion kinase (FAK), a non-receptor tyrosine kinase, plays a crucial role in linking signals initiated by both the extracellular matrix (ECM) and soluble signaling factors and controls essential cellular processes. Extensive evidence has shown that FAK is activated in angiogenic response.

Role of PI3K/Akt and MEK/ERK in mediating hypoxia-induced expression of HIF-1alpha and VEGF in laser-induced rat choroidal neovascularization.

Purpose: The transcription factor hypoxia-inducible factor (HIF)-1 plays a central physiological role in oxygen and energy homeostasis and is activated during hypoxia by stabilization of the subunit HIF-1alpha. Hypoxia plays an important role in the development of choroidal neovascularization (CNV). Expression of HIF-1alpha has been demonstrated in CNV.
