Although the coculture of multiple cell types has been widely employed in regenerative medicine, in vivo transplantation of cocultured cells while maintaining the hierarchical structure remains challenging. Here, a spatially assembled bilayer cell sheet of human mesenchymal stem cells and human umbilical vein endothelial cells on a thermally expandable hydrogel containing fibronectin is prepared and its effect on in vitro proangiogenic functions and in vivo ischemic injury is investigated. The expansion of hydrogels in response to a temperature change from 37 to 4 °C allows rapid harvest and delivery of the bilayer cell sheet to two different targets (an in vitro model glass surface and in vivo tissue)...

Until recently folate receptor alpha (FRα) has only been considered as a folate transporter. However, a novel role of FRα as a transcription factor was reported by our lab. More recently our lab showed a novel pleiotropic role of FRα: (a) direct transcriptional activation of Oct4, Sox2, and Klf4 genes; and (b) repression of biogenesis of miRNAs that target these genes or their effector molecules. These observations beg a question: "Can a simple molecule such as folate be used to manipulate the production and/or differentiation of endogenous neural stem cells (NSCs), which may hold promise for future therapies?" Conditions such as spinal cord injury, motor neuron diseases, Alzheimer's disease and multiple sclerosis may benefit from increasing stem cell pool and promoting specific pathways of differentiation...

Urinary incontinence, or the loss of bladder control, is a debilitating condition affecting millions worldwide, which significantly reduces quality of life. Neuromodulation of lower urinary tract nerves can be used to treat sensations of urgency in many subjects, including those with Spinal Cord Injury (SCI). Event driven, or conditional stimulation has been investigated as a possible improvement to the state-of-the-art open-loop stimulation systems available today. However, this requires a robust, adaptive, and noise-tolerant method of classifying bladder function from real-time bladder pressure measurements...

Biomarker discovery involves finding correlations between features and clinical symptoms to aid clinical decision. This task is especially difficult in resting state functional magnetic resonance imaging (rs-fMRI) data due to low SNR, high-dimensionality of images, inter-subject and intra-subject variability and small numbers of subjects compared to the number of derived features. Traditional univariate analysis suffers from the problem of multiple comparisons. Here, we adopt an alternative data-driven method for identifying population differences in functional connectivity...

To generate voluntary forearm movements, the information that is encoded in the activity of the cortical neurons has to travel through the spinal cord and activate the skeletal muscles. The axons carrying these signals are tightly bundled together in the descending tracts that control the spinal circuitry innervating the forearm muscles. In this paper, we show that corticospinal tract (CST) signals can be used to predict forearm electromyographic (EMG) activities that are recorded during an isometric-pull task...

Gastric ischemia - reperfusion (I/R) injury is an important clinical problem, which is developed in more than 80% of critically ill patients. I/R is caused by interruption of blood supply to an organ or tissue followed by blood reflow into the exposed area, leading to multiple organ failure and death. Gastric reactance has been proposed to measure tissue injury caused by ischemia. The present study evaluates a new method to quantify gastric tissue damage due to I/R, and assess its relation to gastric reactance changes...

Cardiac arrest (CA) is one of the leading causes of mortality and morbidity in the world. Fast, reversible and controllable pharmaceutical-induced hypothermia (PIH) is strongly desired to treat ischemia-reperfusion brain injury. Dihydrocapsaicin (DHC), an agonist of transient receptor potential vanilloid type 1 cation channel (TRPV1), is an emerging candidate for PIH. Its capability to lower body temperature has been validated in both healthy and stroke animal models. However, DHC has shown cardiovascular effects and its safety and feasibility in a CA model has not been tested...

Measurements of health indicators are rarely available for every population and period of interest, and available data may not be comparable. The Guidelines for Accurate and Transparent Health Estimates Reporting (GATHER) define best reporting practices for studies that calculate health estimates for multiple populations (in time or space) using multiple information sources. Health estimates that fall within the scope of GATHER include all quantitative population-level estimates (including global, regional, national, or subnational estimates) of health indicators, including indicators of health status, incidence and prevalence of diseases, injuries, and disability and functioning; and indicators of health determinants, including health behaviours and health exposures...

INTRODUCTION: Patients with nontraumatic acute intracranial pathology benefit from neurointensivist care. Similarly, trauma patients with and without traumatic brain injury (TBI) fare better when treated by a dedicated trauma team. No study has yet evaluated the role of specialized neurocritical (NICU) and trauma intensive care units (TICU) in the management of TBI patients, and it remains unclear which TBI patients are best served in NICU, TICU, or general (Med/Surg) ICU. METHODS: This study is a secondary analysis of The American Association for the Surgery of Trauma Multi-Institutional Trials Committee (AAST-MITC) decompressive craniectomy study...

As an essential component of cellular defense against a variety of endogenous and exogenous stresses, nuclear factor erythroid 2-related factor 2 (Nrf2) has received increased attention in the past decades. Multiple studies indicate that Nrf2 acts not only as an important protective factor in injury models but also as a downstream target of therapeutic agents. Activation of Nrf2 has increasingly been linked to many human diseases, especially in central nervous system (CNS) injury such as traumatic brain injury (TBI)...

BACKGROUND: Nerve injury may induce neuropathic pain. In studying the mechanisms of orofacial neuropathic pain, attention has been paid to the plastic changes that occur in the trigeminal ganglia (TGs) and nucleus in response to an injury of the trigeminal nerve branches. Previous studies have explored the impact of sciatic nerve injury on dorsal root ganglia (DRGs) and it has shown dramatic changes in the expression of multiple biomarkers. In large, the changes in biomarker expression in TGs after trigeminal nerve injury are similar to that in DRGs after sciatic nerve injury...

"Adaptive" responses of the liver to chronic alcohol consumption may underlie the development of cell and tissue injury. Alcohol administration can perturb multiple signalling pathways including phosphoinositide-dependent cytosolic calcium ([Ca(2+) ]i ) increases, which can adversely affect mitochondrial Ca(2+) levels, reactive oxygen species production and energy metabolism. Our data indicate that chronic alcohol feeding induces a leftward shift in the dose-response for Ca(2+) -mobilizing hormones resulting in more sustained and prolonged [Ca(2+) ]i increases in both cultured hepatocytes and hepatocytes within the intact perfused liver...

A middle-aged Japanese man who had been on haemodialysis treatment for diabetic nephropathy developed multiple itchy papules and nodules, which were histopathologically diagnosed as acquired perforating dermatosis. Two years later he developed oral lesions and subsequently numerous erosive plaques with necrotic crusts on the trunk and extremities. Histopathology of a papule showed a parakeratotic plug intermingled with basophilic, necrotic debris and collagen bundles, along with penetration of collagen bundles across the epidermis and subepidermal blister...
