OBJECTIVE: The public health benefits of injury prevention programmes are maximised when programmes are widely adopted and adhered to. Therefore, these programmes require appropriate implementation support. This study evaluated implementation activity outcomes associated with the implementation of FootyFirst, an exercise training injury prevention programme for community Australian football, both with (FootyFirst+S) and without (FootyFirst+NS) implementation support. METHOD: An evaluation plan based on the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) Sports Setting Matrix was applied in a controlled ecological evaluation of the implementation of FootyFirst...

After liver injury, regeneration manifests as either (1) hepatocytes proliferating to restore the lost hepatocyte massor (2) if hepatocyte proliferation is compromised, biliary epithelial cells (BECs) dedifferentiating into liver progenitor cells (LPCs), which subsequently differentiate into hepatocytes. Following pharmacogenetic ablation of hepatocytes in Tg(fabp10a:CFP-NTR) zebrafish, resulting in severe liver injury, signal transducer and activator of transcription 3 (Stat3) and its target gene and negative regulator, socs3a , were upregulated in regenerating livers...

BACKGROUND: Plasmodium knowlesi is the most common cause of human malaria in Malaysia. Acute kidney injury (AKI) is a frequent complication. AKI of any cause can have long-term consequences, including increased risk of chronic kidney disease, adverse cardiovascular events and increased mortality. Additional management strategies are therefore needed to reduce the frequency and severity of AKI in malaria. In falciparum malaria, cell-free haemoglobin (CFHb)-mediated oxidative damage contributes to AKI...

Modulating oxidative stresses and inflammation can potentially prevent or alleviate the pathological conditions of diseases associated with the nervous system, including ischemic optic neuropathy. In this study we evaluated the anti-neuroinflammatory and neuroprotective activities of Rhus coriaria ( R. coriaria) extract in vivo. The half maximal inhibitory concentration (IC50 ) for DPPH, ABTS and β⁻carotene were 6.79 ± 0.009 µg/mL, 10.94 ± 0.09 µg/mL, and 6...

OBJECTIVES: To assess the feasibility of inducing different severities of shock wave (SW)-induced traumatic brain injury (TBI) using lithotripsy. METHODS: Wistar rats (n = 36) were divided into 2 groups: group 1 (n = 20) received 5 SW pulses, and group 2 (n = 16) received 15 SWs pulses. The SW pulses were delivered to the right side of the frontal cortex. Neurologic and behavioral assessments (Garcia test, beam walking, rotarod, and elevated plus maze) were performed at the baseline and at 3, 6, 24, 72, and 168 hours after injury...

The study aims to describe the tissue plasticity of MTJ through the morphological analysis of MTJ soleus in ovariectomized aged female Wistar rats submitted to aquatic training. Forty aged Wistar rats, 1 year and 2 months of age, were divided into four groups: sedentary (S), trained (T), ovariectomized (O), and trained/ovariectomized (OT). Employing the transmission electron microscopy, the ultrastructural and morphometric elements were revealed. In the S group, changes in morphological characteristics as a consequence of the aging process were seen, demonstrated by the conical shape of the muscle cell extremity, a large area with collagen deposit, and misalignment of sarcomeres in series...

In sepsis, the liver plays a crucial role in regulating immune responses and is also a target organ for immune-related injury. Despite the critical function of CD8+ T cells against opportunistic viral infections, the CD8 immune response in the liver during sepsis remains elusive. Here we found that Tim-3 is highly up-regulated in liver CD8+ T cells in a mouse cecal ligation and puncture model and in peripheral blood CD8+ T cells of human patients with sepsis. The expression of Tim-3 in liver CD8+ T cells displayed a bi-phasic pattern and deletion of Tim-3 led to reduction of CD8+ T cell apoptosis...

Traumatic brain injury-induced acute lung injury (TBI-ALI) is a serious complication of traumatic brain injury (TBI). Our previous clinical study found that high levels of blood glutamate after TBI were closely related to the occurrence and severity of TBI-ALI, while it remains unknown whether a high concentration of blood glutamate directly causes or aggravates TBI-ALI. We found that inhibition of the adenosine A2A receptor (A2AR) after brain injury alleviated the TBI-ALI; however, it is unknown whether lowering blood glutamate levels in combination with inhibiting the A2AR would lead to better effects...

Tibial spine fractures are uncommon injuries affecting the insertion of the anterior cruciate ligament on the tibia. They typically occur in skeletally immature patients aged 8 to 14 years and result from hyperextension of the knee with a valgus or rotational force. Diagnosis is based on history, physical examination, and standard radiographs. The use of MRI can identify entrapped soft tissue that may prevent reduction. Open or arthroscopic repair is indicated in patients with partially displaced fractures (>5 mm) with one third to one half of the avulsed fragment elevated, in patients who have undergone unsuccessful nonsurgical reduction and long leg casting or bracing, and in patients with completely displaced fractures...

There is emerging evidence suggesting that neurotoxic insults and hypoxic/ischemic injury are underlying causes of Parkinson's disease (PD). Since PTEN-induced kinase 1 (PINK1) dysfunction is involved in the molecular genesis of PD and since our recent studies have demonstrated that the δ-opioid receptor (DOR) induced neuroprotection against hypoxic and 1-methyl-4-phenyl-pyridimium (MPP+ ) insults, we sought to explore whether DOR protects neuronal cells from hypoxic and/or MPP+ injury via the regulation of PINK1-related pathways...

The complex nature of ankle fractures is magnified when seen in patients at high risk of soft tissue wound healing complications. The major categories include associated soft tissue injury, diabetes, tobacco use, peripheral vascular disease, malnutrition, alcoholism, and corticosteroid use. Because of the potential for wound dehiscence and infection with open reduction and internal fixation of ankle fractures in these patients, minimally invasive procedures have been described. The aims of the present study were to assess the possibility for, and evaluate the results and complications of, minimally invasive techniques for different types of malleolar fractures in high-risk patients...

The maxilla is arguably the most anatomically intricate structure of the craniofacial skeleton, and the hard palate is an important bone that regulates the width and architecture of the face. The management of palatal fractures has long been a matter of debate, and varies with anatomical pattern and other injuries to the craniofacial skeleton. We have studied 18 palatal fractures during a five-year period that were treated using 3-dimensional rectangular plates placed across the palatal vault together with fixation of other fractures of the facial bones...

Cerebral small vessel disease (CSVD) is a leading cause of progressive decline of cognition and a major risk factor for stroke. Thymoquinone (TQ) is the major biological component of Nigella sativa (N. sativa) and its extracts. We explored the possible protective effect of TQ against CSVD in strokeprone spontaneously hypertensive SHRsp rats. Morris water maze and novel object recognition tests were conducted to evaluate memory and cognitive function. mRNA expression of inflammatory factors were determined and oxidative stress was evaluated...

Stroke is considered a major cause of global morbidity. Currently, there are no effective treatments for post-stroke cognitive impairment. Enriched environment (EE) has been brought forward as a preconditioning method to induce cerebral tolerance in an ischemic event. However, the subjacent mechanisms involved in this tolerance are not yet clear. Herein we aimed to identify the mechanisms of neuroprotection triggered by EE preconditioning in a murine model of ischemic stroke. In order to do so, C57Bl/6 mice were kept for five weeks either in EE or in standard environment (SC) prior to ischemic injury through bilateral carotid occlusion (BCCAo) or sham surgery...

BACKGROUND: The aim of this study was to determine the individual oxidized phosphatidylcholine (OxPC) molecules generated during renal ischemia/ reperfusion (I/R) injury. METHODS: Kidney ischemia was induced in male Sprague-Dawley rats by clamping the left renal pedicle for 45 min followed by reperfusion for either 6h or 24h. Kidney tissue was subjected to lipid extraction. Phospholipids and OxPC species were identified and quantitated using liquid chromatography coupled to electrospray ionization tandem mass spectrometry using internal standards...

Previous studies have shown that isosteviol sodium (STVNa) protects against permanent cerebral ischemia injury by inhibition of the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB)-mediated inflammatory responses. Overwhelming evidence shows that toll-like receptors (TLRs) are the upstream regulators of NF-κB. On the basis of the similarity of the pathology caused by traumatic brain injury (TBI) and stroke, we speculated that STVNa may have a therapeutic effect against TBI through regulation of the TLRs/NF-κB signaling-mediated inflammatory response...

Treating patients with bilateral posterior pelvic ring injuries can be challenging. Placement of transiliac-transsacral style screws in available S1 or S2 osseous fixation pathways is becoming an increasingly common fixation method for these unstable injuries. We propose a percutaneous technique that sequences reduction and stabilization of 1 hemipelvis with at least 1 transiliac-transsacral screw and then uses the existing transiliac-transsacral screw and accompanying guide wires to assist in temporary stabilization and definitive fixation of the second hemipelvis...
