Our findings provided an experimental basis for ART to become a drug for the treatment of liver fibrosis.

Our results show that IRP2-Iron-ROS axis is necessary for ART to induce ferroptosis in HSC and play an anti-fibrotic effect.

Recent evidence has showed that mitophagy acts as a central player for maintaining mitochondrial homeostatis through elimination of damaged mitochondria, leading to the prevention of hyperinflammation triggered by NLRP3 activation. In this study, we aimed at investigating the potential role of PTEN-induced kinase 1 (PINK1)-mediated mitophagy in hepatic I/R injury. C57BL/6 mice subjected to partial warm hepatic I/R or primary KCs exposed to anoxia/reoxygenation (A/R) was used as in vivo or in vitro model, respectively. Mitophagy was measured by protein levels of PINK1, Parkin, LC3B-II, TOMM20 and p62. NLRP3, caspase-1 and IL-1β at mRNA and/or protein levels were used as indicators of inflammasome activation. Oesults support a critical role of PINK1-mediated mitophagy in mitochondrial quality control for KC activation and function in hepatic I/R.
Children with medical complexity (CMC) have high rates of emergency department (ED) utilization, but little evidence exists on the perceptions of parents and pediatric emergency medicine (PEM) physicians about emergency care. We sought to explore parent and PEM physicians' perspectives about 1) ED care for CMC, and 2) how emergency care can be improved.

We performed semistructured interviews with parents and PEM physicians at a single academic, children's hospital. English-speaking parents were selected utilizing a standard definition of CMC during an ED visit in which their child was admitted to the hospital. All PEM physicians were eligible. We developed separate interview guides utilizing open-ended questions. The trained study team developed and modified a coding tree through an iterative process, double-coded transcripts, monitored inter-rater reliability to ensure adherence, and performed thematic analysis.

Twenty interviews of parents of CMC and 16 of PEM physicians were necessary for saturation..
In the present study, we sought to determine whether early preemptive scheduling of inferior vena cava filter (IVCF) removal during the preoperative IVCF placement visit would affect the IVCF removal rate.

All electronically documented IVCF placements at a single institution were reviewed from April 2015 to July 2019. The baseline characteristics included age, the clinical indications for IVCF placement, inpatient/outpatient status, and type of IVCF placed. Statistical analysis was performed using the χ
for discrete variables and the two-tailed paired t test for continuous variables.

A total of 599 patients (mean age, 68years; 273 women and 326 men) had undergone technically successful IVCF placement. During the preoperative consent process for placement, 232 patients had been scheduled for IVCF removal within 3months after placement. However, 367 patients had not been scheduled for removal at the preoperative consent process. The indications for placement included failure of anticoagulation, a contraIVCF removal during the placement encounter significantly increased the IVCF removal rate. This approach could be a viable option for institutions where clinic time and/or resources are limited or unavailable and for patients who have difficulty traveling for clinical evaluations.Odor information is processed in the olfactory bulb (OB), which is organized into olfactory inputs, interneurons, projection neurons, and centrifugal inputs, and these various structures regulate olfactory information processing. Similar to other brain regions, the OB structures include many types of interneurons, including γ-aminobutyric acid (GABA)ergic interneurons. Many interneurons are granule cells that are found in the granule cell layer (GCL), which is a deep layer of the OB. Interestingly, these interneurons exhibit variations in GABA immunoreactivity, and previous studies have observed differing intensities among morphologically and chemically similar neuronal populations. However, the numbers and distribution patterns of cells that show variations in GABA immunoreactivity are unknown. Therefore, we observed and quantitatively analyzed this diversity in the GCL of the mouse OB using immunogold, high-voltage electron microscopy, combined with light microscopy. Consequently, our results clearly show variations in the GABA immunoreactivity among GCL interneurons, which suggested heterogeneity in the amount of GABA present in each interneuron and reflected the possibility that different amounts of neuroactive substances may be associated with different functions for the various GABAergic interneuron groups. Variations in GABA immunoreactivity could be a novel criterion for classifying interneuron subpopulations.
The purposes of this study were to explore the optimal time for starting walking training in the first month after spinal cord injury (SCI) in rats and to discuss the relationship between changes in motor function and transcranial electrical motor evoked potentials (tceMEPs).

Four groups of rats with SCI (BSWTT-3, 7, 14, 12) performed body-weight-supported treadmill training (BWSTT) for three weeks beginning at 3, 7, 14, and 21 days after SCI, respectively. The Basso, Beattie, and Bresnahan (BBB) score and tceMEPs were assessed weekly. Weekly repeated measures and multiple comparisons between groups were performed to identify differences in motor function and tceMEPs. Correlation analysis was performed to clarify the relationship between BBB scores and tceMEPs over time.

Although there was no significant difference between the BWSTT-14 group and the other three BWSTT groups at the end of the experiment in terms of BBB scores and the latency of tceMEPs, the BWSTT-14 group obtained the best trends in impr Sham group did not undergo BWSTT, which made the training itself a confounding factor for the results.Ozone (O3) is a short-lived molecule which can be produced in a controlled reaction when oxygen is exposed to electric discharge. In the last few decades, many publications dealing both with animals and humans reported beneficial effects of ozone administration linked to its immunomodulatory and protective role against cellular damage. This is the first work which brings insight into how ozone influences cells of neural lineage in vitro and hypothesizes the potential molecular and novel electromagnetic mechanisms behind its action. By using neural stem cells, we show that ozone, especially in concentrations of around 11 μg/mL, significantly increases the speed of neural cell migration. With much lower effects, it also increases cell proliferation and cytokine production. Results of this study, at least partly, explain the observed beneficial effects of ozone in diseases of the nervous system tested on animal models and in human clinical trials. Therefore, here described effects of ozone on cellular level represent a firm basis for further investigation of possible applications of ozone in regeneration of the nervous system.
Tumor necrosis factor-a (TNF-α) signaling pathway plays a significant role in Alzheimer's disease (AD). This study aimed to explore the relationship between TNF-α related inflammatory proteins and pathological markers of AD, and examine their possibility as a predictor of the conversion of mild cognitive impairment (MCI) to AD.

This study included both cross-sectional and longitudinal designs. The levels of TNF-α related inflammatory proteins, Aβ
, total-tau(t-tau), phosphorylated tau (p-tau) from cerebrospinal fluid (CSF) were analyzed in healthy controls (HC, n = 90), MCI (n = 116), and AD participants (n = 75) from the Alzheimer's Disease Neuroimaging Initiative (ADNI). Kaplan-Meier analyses were used to evaluate the predictive value of the examined putative AD markers after follow-up visits.

In the cross-sectional cohort, we observed higher CSF levels of TNF-α related inflammatory proteins in the MCI and AD patients with positive tau pathology. TNF receptors (TNFR) were more closely associated with t-tau and p-tau than Aβ
, in HC, MCI and AD subjects. In the longitudinal cohort with a mean follow-up of 30.2 months, MCI patients with high levels of CSF TNFR1 (p = 0.001) and low levels of TNFR2 (p < 0.001) were more likely to develop into AD.

TNFR-signaling might be involved in the early pathogenesis of AD and TNF receptors may serve as potential predictive biomarkers for MCI.

We describe a case in a 28-year-old male with a history of chronic abdominal pain who presented to our facility in hemorrhagic shock secondary to a ruptured transverse mesocolon middle colic aneurysm status postemergent transverse colectomy. He was found to have chronic vertebral, renovisceral, and iliac aneurysms as well as acute superior and inferior mesenteric artery dissection and chronic bilateral vertebral artery dissections. He subsequently developed disseminated intravascular coagulopathy, resulting in saddle pulmonary embolus as well as right renal artery and splenic artery thrombosis. Ultimately, the patient expired.Type Ia endoleaks are a complication of endovascular aneurysm repair that require intervention due to the increased risk of aneurysmal rupture. Many techniques have been studied in order to minimize the occurrence of these complications, as well as to aid in their repair. click here We introduce the utilization of intravascular ultrasound in conjunction with the endovascular EndoAnchor systems for the repair of a complex type Ia endoleak in an infrarenal aortic stent graft. This technique allowed us to have real-time feedback of EndoAnchor placement and aortic wall to stent graft apposition with a reduction in radiation exposure and contrast dye load.
In this study, we sought to assess knowledge, attitudes, and behaviors regarding venous thromboembolism (VTE) prophylaxis among clinicians at a tertiary hospital of China.

An electronic questionnaire was sent to clinicians to gather information regarding demographic data (5 items), knowledge about VTE prophylaxis (21 items), behaviors regarding VTE prophylaxis (8 items), and attitudes regarding VTE prophylaxis (7 items). Answers of "strongly agree" and "agree" on the behaviors and attitude items were defined as affirmative responses. Clinicians were also asked to provide suggestions regarding VTE prophylaxis.

A total of 867 clinicians were included in this study. The overall correct response rate for knowledge items was 60.9%. The median affirmative response rate for behavior items was 48.6% (range 29.5-80.3%), and the median affirmative response rate for attitude items was 98.7% (range 96.9-99.3%). Clinicians were most concerned about the adverse effects triggered by chemical VTE prophylaxis (79.5%) and possibility of a financial penalty when a patient could not be treated with VTE prophylaxis (72.
