The alleviation of pain and prevention of suffering are key aspects of animal welfare. Unfortunately, analgesic drugs are not available for all species. White rhinoceros (Ceratotherium simum), representing one of such species, which survive poaching attempts inflicted with severe facial injuries and gunshot wounds, nonetheless require analgesic support. To improve treatment conditions, this study explored the use of carprofen for the treatment of pain and inflammation in white rhinoceros. The pharmacokinetics of 1 mg/kg intramuscular carprofen was evaluated in six healthy white rhinoceros...

BACKGROUND/AIMS: Increasing evidence links microRNAs to the pathogenesis of peripheral vascular disease. We recently found microRNA-125b (miR-125b) to be one of the most significantly down‑regulated microRNAs in human arteries with arteriosclerosis obliterans (ASO) of the lower extremities. However, its function in the process of ASO remains unclear. This study aimed to investigate the expression, regulatory mechanisms, and functions of miR-125b in the process of ASO. METHODS: Using the tissue explants adherent method, vascular smooth muscle cells (VSMCs) were prepared for this study...

Tissue wound repair has been studied extensively. It involves the coordinated activation of several intracellular and intercellular pathways, as well as remodeling from the sequential recruitment of different cell types to the wound site. There is, however, an equally important process that happens at the single cell level, when the integrity of the plasma membrane is compromised. Individual eukaryotic cells can rapidly repair their plasma membrane after injury, through a process that restores internal homeostasis and prevents cell death...

Remodeling of cardiac tissue architecture is essential for normal organ development and maintaining homeostasis after injury. Injurious insults to the heart, such as hypertension and myocardial infarction, promote cellular responses including stimulation of resident inflammatory cells, activation of endothelial cells and recruitment of immune cells, hypertrophy of cardiomyocytes, and activation of fibroblasts. The physiological goal of this coordinated cellular response is to repair damaged tissue while maintaining or restoring cardiac contractile function...

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...

BACKGROUND: Liver fibrosis results from a wound healing response to chronic injury, which leads to excessive matrix deposition. Genome wide association studies have showen transcriptional dysregulation in mild and severe liver fibrosis. Recent studies suggested that genetic markers may be able to define the exact stage of liver fibrosis. AIM: To define genes or genetic pathways that could serve as markers for staging or as therapeutic targets to halt progression of liver fibrosis...

Accidental cut-throat injuries are extremely rare and usually involve a sharp-edged weapon. In this paper, two cases of a cut-throat wound to two auto-rickshaw drivers are presented where the broken windshield of the auto-rickshaws was responsible for the wounds. In both the cases, fatal incised wounds were present over the neck, cutting the soft tissue along with the major vessels. The death occurred due to exsanguination caused by neck-vessel injury in one case and trachea along with neck-vessel injury in the second case...

Context: The outcome of patients with depressed fracture varies and depends on multiple factors. There has been no previous study on the significance of these factors on the outcome of depressed fracture of the skull and hence this study. Aims: The primary aim of our study is to find the factors affecting the outcome in cases of depressed skull fracture (DSF). This will help us improve outcomes and give more accurate prediction of long-term outcomes. Settings and Design: Prospective observational study...

Background: There has been a substantial increase in the number of cases with head injuries in the past two decades which has simultaneously led to increase in the annual incidence of depressed fractures of skull. Most of these skull fractures are associated with considerable morbidity and mortality of patients and an unavoidable financial burden on the family members. However, many changes have been undertaken directed toward improved management of patients with head injuries and skull fractures in the past 20 years...

In developing countries, during the harvest season, winnower blade injuries occur very frequently in children and results in lifelong disability. Nine children were managed during 1 month, all resulting due to winnower blade induced craniofacial trauma. PubMed search for "fan blade injury" showed two case series and three case reports. In our study, 88% had compound depressed fracture; brain matter leak in 56%, cerebrospinal fluid (CSF) leak alone in 22%. 66.7% had injury involving the frontal bone...

The multifactorial complexity of spinal cord injuries includes the formation of a glial scar, of which chondroitin sulphated proteoglycans (CSPG) are an integral component. Previous studies have shown CSPG to have inhibitory effects on endothelial and neuronal cell growth, highlighting the difficulty of spinal cord regeneration. Mesenchymal stem/stromal cells (MSC) are widely used a cell therapy, and there is mounting evidence for their angiogenic and neurotrophic paracrine properties. However, in vivo studies have observed poor engraftment and survival of MSC when injected into SCI...

BACKGROUND CONTEXT: Unrecognized and inadequately repaired intraoperative durotomies may lead to cerebrospinal fluid leak, pseudomeningocele, and other complications. Few studies have investigated durotomy that is unrecognized intraoperatively and requires additional postoperative management (hereafter, late-presenting dural tear [LPDT]), though estimates of LPDT range from 0.6 - 8.3 per 1,000 spinal surgeries. These single-center studies are based on relatively small sample sizes for an event of this rarity, all with <10 patients experiencing LPDT...

Myofibroblasts play key roles in wound healing and pathologic fibrosis. Here we undertook an RNAi screen to characterize myofibroblast regulatory genes, using a high-content imaging approach to quantify alpha-smooth muscle actin stress fibers in cultured human fibroblasts. Screen hits were validated on physiological compliance hydrogels, and selected hits tested in primary fibroblasts from patients with idiopathic pulmonary fibrosis. Our RNAi screen led to the identification of STAT3 as an essential mediator of myofibroblast activation and function...

Ichthyophthirius multifiliis is a ciliated protozoan parasite recognized as one of the most pathogenic diseases of wild and cultured freshwater fish. Fish skin mucus plays a significant role against invading pathogens. However, the protein-based modulation against infection with I. multifiliis, of host fish at this barrier is unknown. Thus, we investigated the skin mucus proteome of common carp using a shotgun proteomic approach at days 1 and 9 after I. multifiliis exposure. We identified 25 differentially expressed proteins in infected carp skin mucus...

Wound and ostomy nurses receive specialty training and certification to provide care in abdominal stomas, ostomies, wounds, fistulas, and pressure injuries. The eight existing nationwide programs in 2011 were inadequate to meet increasing patient population demands. We developed an innovative nondegree, postbaccalaureate continuing wound and ostomy education program using a hybrid design. The program integrated interactive online classes with intensive onsite classes and skills training. The program has been granted seven-year accreditation; student evaluations have been positive...
