Development and validation of a nomogram model of depression and sleep disorders and the risk of disease progression in patients with breast cancer.

Background: In this study, we investigated the relationship between the risk of postoperative progressive disease (PD) in breast cancer and depression and sleep disorders in order to develop and validate a suitable risk prevention model.

Methods: A total of 750 postoperative patients with breast cancer were selected from the First People's Hospital of LianYunGang, and the indices of two groups (an event group and a non-event group) were compared to develop and validate a risk prediction model. The relationship between depression, sleep disorders, and PD events was investigated using the follow-up data of the 750 patients.

Development and Validation of a Clinical Model for Predicting Delay in Postoperative Transfer Out of the Post-Anesthesia Care Unit: A Retrospective Cohort Study.

Objective: We aimed to analyze the factors related to delay in transfer of patients in the post-anesthesia care unit (PACU) and to develop and validate a prediction model for understanding these factors to guide precise clinical intervention.

Methods: We collected data from two cohorts of 1153 and 297 patients who underwent surgery and were treated in the PACU at two time points. We examined their clinical features and anesthesia care data using analytical methods such as logistic regression, Random Forest, and eXtreme Gradient Boosting (Xgboost) to screen out variables and establish a prediction model.

Effectiveness of conjunctival bleb scarring by knock-down of heat shock protein 47 in rat model.

Aim: To evaluate the effectiveness of knock-down of heat shock protein 47 (HSP47) on conjunctival bleb scarring in a rat model and its possible mechanism.

Methods: Male Sprague-Dawley rats were used for glaucoma filtration surgery (GFS) and were treated with either phosphate buffered solution, shControl, mitomycin C, or sh-HSP47 using a microsyringe immediately after GFS. The morphology of filtering blebs was observed postoperatively.

Multifunctional xyloglucan-containing electrospun nanofibrous dressings for accelerating infected wound healing.

Preventing wound infection is a major challenge in biomedicine. Conventional wound dressings often have poor moisturizing and antimicrobial properties unfavorable for wound healing. In this study, we prepared a multifunctional electrospun nanofiber dressing (PCQX-M) containing xyloglucan, quaternized chitosan, Polyvinyl alcohol, and collagen.

High Levels of Heat Shock Protein 47 in the Aqueous Humor of Patients with Acute Primary Angle Closure.

Introduction: Acute primary angle closure (APAC) is often characterized by acute elevation of intraocular pressure accompanied by severe ocular and systemic symptoms. Excessive collagen accumulation, which can be caused by upregulated heat shock protein 47 (HSP47) expression, can produce scarring in rat conjunctival blebs. Meanwhile, the presence of HSP47 in human aqueous humor and its levels are yet to be determined.

Inhibition of RIPK1 by ZJU-37 promotes oligodendrocyte progenitor proliferation and remyelination via NF-κB pathway.

Receptor interacting serine/threonine protein kinase 1 (RIPK1) activation and necroptosis have been genetically and mechanistically linked with human multiple sclerosis and neurodegenerative diseases for which demyelination is a common key pathology. Demyelination can be healed through remyelination which is mediated by new oligodendrocytes derived from the adult oligodendrocyte progenitor cells (OPCs). Unfortunately, the efficiency of remyelination declines with progressive aging partially due to the depletion of OPCs following chronic or repeated demyelination.

Accumulation of Astaxanthin by Co-fermentation of Spirulina platensis and Recombinant Saccharomyces cerevisiae.

This study aimed to explore an effective, simple, and time-saving method for astaxanthin accumulation. Wild-type Saccharomyces cerevisiae as a bioreactor, the SpcrtR gene was first ligated with the signal peptide S to construct pYES2/NT-A-S-SpcrtR plasmid in Saccharomyces cerevisiae. The detection of SDS-PAGE and Western blotting protein proved that SpCRTR was successfully extracellular expressed in Saccharomyces cerevisiae.

Protective effect of fermented Diospyros lotus L. extracts against the high glucose-induced apoptosis of MIN6 cells.

Date plum persimmon (Diospyros lotus L.) is a fruit crop from the Ebenaceae family. Its microorganism-fermented extract (DPEML) was shown to exhibit a hypoglycemic effect in our previous work.

Amygdalar Endothelin-1 Regulates Pyramidal Neuron Excitability and Affects Anxiety.

An abnormal neuronal activity in the amygdala is involved in the pathogenesis of anxiety disorders. However, little is known about the mechanisms. High-anxiety mice and low-anxiety mice, representing the innate extremes of anxiety-related behaviors, were first grouped according to their anxiety levels in the elevated plus maze test.

Infralimbic Endothelin1 Is Critical for the Modulation of Anxiety-Like Behaviors.

Endothelin1 (ET1) is a potent vasoconstrictor that is also known to be a neuropeptide that is involved in neural circuits. We examined the role of ET1 that has been implicated in the anxiogenic process. We found that infusing ET1 into the IL cortex increased anxiety-like behaviors.

[Effects of oxidative stress on barrier function of human retina pigment epithelium and its molecular mechanisms].

Objective: To investigate the effects of hydrogen peroxide (H2O2) on the barrier function and expression of tight junction protein in human retinal pigment epithelium (RPE) cells.

Methods: Experimental study. The human RPE cell line (D407) were cultured and treated with (H2O2 treated group) or without H2O2 (normal control group).
