The principle aim of the present study was to assess how the severity of spinal cord injury (SCI) affects LV mechanics, function, and underlying cardiomyocyte morphology. Here, we utilized different severities of T3 spinal cord contusions (MODERATE, 200Kdyn contusion; SEVERE, 400kdyn contusion; SHAM) and combined standard echocardiography with speckle tracking analyses to investigate in vivo cardiac function and deformation (contractility) after experimental SCI in the Wistar rat. In addition, we investigated changes in the intrinsic structure of cardiac myocytes ex vivo...

Renal ischemia-reperfusion is a main cause of acute kidney injury (AKI), which is associated with high mortality. Here we show that extracellular vesicles (EVs) secreted from hiPSC-MSCs play a critical role in protection against renal I/R injury. hiPSC-MSCs-EVs can fuse with renal cells and deliver SP1 into target cells, subsequently active SK1 expression and increase S1P formation. Chromatin immunoprecipitation (ChIP) analyses and luciferase assay were used to confirm SP1 binds directly to the SK1 promoter region and promote promoter activity...

OBJECTIVES: All Terrain Vehicles (ATVs) are increasing in popularity and becoming larger and faster at a production level. As a Level I Trauma Center, we perceived a disproportionately high volume of ATV-related admissions. Our goal was to study injury patterns and severity in adult and pediatric populations. METHODS: All ATV-related trauma admissions at a single Level I trauma center were retrospectively analyzed over a seven-year period. RESULTS: On-road incidents were more likely to result in a higher average Injury Severity Score (ISS) (p < 0...

BACKGROUND: Cell-free DNA (cfDNA) comprises short, double-stranded circulating DNA sequences released from damaged cells. In people, cfDNA concentrations correlate well with disease severity and tissue damage. No reports are available regarding cfDNA kinetics in dogs. OBJECTIVES/HYPOTHESIS: Cell-free DNA will have a short biological half-life and would be able to stratify mild, moderate, and severe tissue injury. Our study aims were to determine the kinetics and biological half-life of cfDNA and to contrast them with those of creatine kinase (CK)...

Dog bite injuries are common sources of morbidity with an estimated incidence of 4.5 million bites per year with over 350,000 requiring treatment in the emergency room. Children under the age of 14 are most likely to be affected with a peak age of 5-9 years old. We report a case of a 24-month-old female who sustained a large composite facial avulsion injury from a pit bull dog bite. The avulsed tissue involved a substantial portion of the patient's mid-face, including the entire soft tissue of the nose, upper lip, part of the left cheek, and left oral commissure...

RATIONALE: Recent evidence indicates that histone deacetylase enzymes (HDACs) contribute to ischemia reperfusion (I/R) injury, and pan-HDAC inhibitors have been shown to be cardioprotective when administered either before an ischemic insult or during reperfusion. We have shown previously that selective inhibition of class I HDACs provides superior cardioprotection when compared to pan-HDAC inhibition in a pretreatment model, but selective class I HDAC inhibition has not been tested during reperfusion, and specific targets of class I HDACs in I/R injury have not been identified...

BACKGROUND/AIMS: Regulatory T cells (Tregs) can suppress immunologic damage in myocardial ischaemia/reperfusion injury (MIRI), however, the isolation and ex vivo expansion of these cells for clinical application remains challenging. Here, we investigated whether the IL-2/anti-IL-2 complex (IL-2C), a mediator of Treg expansion, can attenuate MIRI in mice. METHODS: Myocardial I/R was surgically induced in male C57BL/6 mice, aged 8-10 weeks, that were randomly assigned to 1) sham group (Sham), 2) Phosphate Buffered Saline (PBS), 3) IL-2-anti-IL-2 Ab complex (IL-2C), or 4) sham group, 5) PBS, 6) IL-2C after MIRI, or 7) IL-2C, 8) IL-2C+anti-CD25 mAbs, or 9) IL-2C; 10) IL-2C+anti-TGF-β1 mAbs, 11) IL-2C+anti-IL-10 mAbs...

PURPOSE: Pharmacologic preconditioning, through activating several mechanisms and mediators, can increase the tolerance of different tissues against ischemia/reperfusion (I/R) injury. Recent studies have shown that morphine preconditioning has protective effects in different organs, especially in the heart. Nevertheless, its mechanisms are not well elucidated in the brain. The present study aimed to clarify whether the activation of mitochondrial KATP (mKATP) channels in chronic morphine (CM) preconditioning could decrease hippocampus damage following I/R injury...

Few risk factors for nonsuicidal self-injury (NSSI) have been identified. This study investigated diminished aversion toward self-injury (i.e., NSSI, suicide/death stimuli) and self-criticism as unique NSSI risk factors. After terminating a treatment study, 154 adults with a recent and frequent NSSI history completed self-report and computer-based measures of psychopathology, implicit and explicit self-criticism, and implicit aversion to NSSI and suicide/death. Participants were then contacted 4 weeks later to test factors predicting NSSI frequency over this follow-up period...

TGF-β/Smad signaling plays an important role in diabetic nephropathy. The present study identified a novel Smad3-dependent long non-coding RNA (lncRNA) Erbb4-IR in the development of type-2 diabetic nephropathy (T2DN) in db/db mice. We found that Erbb4-IR was highly expressed in T2DN of db/db mice and was specifically induced by AGE via a Smad3-dependent mechanism. The functional role of Erbb4-IR in T2DN was revealed by kidney-specific silencing of Erbb4-IR to protect against the development of T2DN such as elevated microalbuminuria, serum creatinine and progressive renal fibrosis in db/db mice, and to block AGE-induced collagen I and IV expression in mouse mesangial cells (mMCs) and mouse tubular epithelial cells (mTECs)...

We defined how blood-derived vitronectin (VTN) rapidly and potently activates leukemia inhibitory factor (LIF) and pro-inflammatory interleukin 6 (IL-6) in vitro and after vascular injury in the brain. VTN (not fibrinogen, fibronectin, laminin-111, collagen-I) robustly increased LIF and IL-6 within 4 hr in C6-astroglioma cells, while VTN-/- mouse plasma was less effective than wildtype. LIF and IL-6 were induced by intracerebral injection of rhVTN in mice, but less by intracerebral hemorrhage in VTN-/- than wildtype littermates...
