The present study measured hepatic transcriptome responses in male rainbow darter (Etheostoma caeruleum) exposed to 2 municipal wastewater treatment plants (MWWTPs) (Kitchener and Waterloo) over 4 fall seasons (2011 - 2014) in the Grand River Ontario. The overall goal was to determine if upgrades at the Kitchener MWWTP (in 2012) resulted in transcriptome responses indicative of improved effluent quality. The number of differentially expressed probes in fish downstream of the Kitchener outfall (904-1,223), remained comparable to that downstream of Waterloo (767-3,867)...

We compared the therapeutic effects and mechanism of transplanted human dental pulp stem cells (hDPSCs) and human bonemarrow-derived mesenchymal stem cells (hMSCs) in a stroke model of rats and an <i>in vitro</i> ischemic model. Both hDPSCs- and hMSCs- intravenously injected rats 24&#8201;h after middle cerebral artery occlusion showed improved functional recovery and reduced infarct volume versus control rats, but the hDPSCs group showed greater reduction in infarct volume than hMSCs. The positive area for the endothelial cell marker was greater in the lesion boundary areas in the hDPSCs group than with hMSCs...

BACKGROUND: Ischemia/reperfusion injury during kidney transplantation (KTx) delays allograft recovery. Hypoxia-inducible factor-1α (HIF-1α) is the key regulator of the protective response to ischemia/reperfusion injury. We evaluated the impact of the HIF-1α signaling pathway on allograft recovery during cadaveric KTx. METHODS: Between 1996 and 2015, 46 patients underwent cadaveric KTx. The expression levels of HIF-1α-related proteins, including phosphoinositide 3-kinase, phosphorylated (p)-Akt, p-mammalian target of rapamycin, p-Eukaryotic translation initiation factor 4E, p-S6 ribosomal protein, and HIF-1α, were immunohistochemically evaluated and semi-quantitatively scored in graft biopsy specimens after 1 hour of revascularization...

BACKGROUND: Optimal treatment for established renal failure is living donor kidney transplantation. However this pathway exposes healthy individuals to significant reduction in nephron mass via major surgical procedure. Laparoscopic donor nephrectomy is now the most common method for live donor transplantation, reducing both donor post-operative pain and recovery time. However this procedure exposes kidneys to additional haemodynamic stresses. It has been suggested that donor hydration-particularly the use of preoperative intravenous fluids-may counteract these stresses, reducing subclinical acute kidney injury and ultimately improving long-term renal function...

New insight regarding limb-dominance effects on temporal-spatial gait parameters is needed to further investigate subjects with recurrent low back pain (LBP). Although an asymmetrical gait pattern was found to reflect natural functional differences, there is a lack of information regarding gender differences on dominant limb support patterns in subjects with LBP. The purpose of this study was to investigate temporal-spatial gait parameters based on limb dominance and gender between subjects with and without LBP...

As one of the virulence factors of Bacillus anthracis, lethal toxin (LT) induces various pathogenic responses including the suppression of the coagulation system. In this study, we observed that LT markedly increased the circulating soluble P-selectin (sP-sel) levels and microparticle (MP) count in wild-type but not P-selectin (P-sel, Selp(-)(-)(-)) or P-sel ligand-1 (PSGL-1, Selplg(-)(-)(-)) knockout mice. Because sP-sel induces a hypercoagulable state through PSGL-1 pathway to generate tissue factor-positive MPs, we hypothesized that the increase in plasma sP-sel levels can be a self-rescue response in hosts against the LT-mediated suppression of the coagulation system...

Bénédicte Franco, Brigitte Malgrange
It is commonly assumed that mammalian cochlear cells do not regenerate. Therefore, if hair cells are lost following an injury, no recovery could occur. However, during the first postnatal week, mice harbor some progenitor cells that retain the ability to give rise to new hair cells. These progenitor cells are in fact supporting cells. Upon hair cells loss, those cells are able to generate new hair cells both by direct transdifferentiation or following cell cycle re-entry and differentiation. However, this property of supporting cells is progressively lost after birth...

BACKGROUND: Atypical hemolytic uremic syndrome is a rare disorder which is known to cause acute thrombotic microangiopathy during pregnancy with poor maternal and fetal outcomes. Atypical hemolytic uremic syndrome is caused mostly by dysregulation of alternative complement pathway secondary to genetic mutations. Most of the cases reported have been in the post-partum period. We report a rare case of a patient who presents with thrombotic microangiopathy in the first trimester of her eleventh pregnancy and was successfully treated with eculizumab...

The objective of this study is to discuss the security and feasibility of the laparoscopic reversal of Hartmann's procedure (LRHP) on the concept of enhanced recovery after surgery (ERAS). The clinical data of 42 patients who underwent laparoscopic reversal of Hartmann's procedure was retrospectively analyzed, and the operative time, blood loss, intraoperative and postoperative complications, conversion to open surgery, postoperative hospital stay, and so on were observed. Twenty-nine patients (69.00 % of the study pool) received complete postoperative recovery courses as prescribed by enhanced recovery program (ERP)...

Adipose tissue is an important energy depot and endocrine organ, and the degree of adiposity impacts the host response to infection. However, little is known regarding the mechanisms by which white adipose tissue (WAT) is lost acutely and then restored after resolution of sepsis. Therefore, signaling pathways governing protein synthesis, autophagy, apoptosis and the ubiquitin-proteasome were investigated to identify potential mechanisms mediating the acute (24 h) loss of WAT after cecal ligation and puncture (CLP) as well as the failure to replenish WAT during recovery (day 10)...

CVD remain the leading cause of death globally. Effective dietary strategies for their reduction are of high priority. Increasing evidence suggests that phytochemicals, particularly dietary flavonoids and nitrates, are key modulators of CVD risk reduction through impact on multiple risk factors. The aim of this review is to explore the evidence for the impact of flavonoid- and nitrate-rich foods and supplements on CVD risk, with specific reference to their importance as mediators of vascular health and platelet function...

Recently, many studies have reported that sensorineural hearing impairment related to neurological disorders may be caused by diabetes mellitus. However, to date, only a small number of studies have investigated the treatment of sensorineural hearing impairment. In the present study, the effects of chlorogenic acid on diabetic auditory pathway impairment were evaluated by neuro-electrical physiological measurements and morphological investigations. We have shown that CA efficiently prevents the progression of auditory pathway dysfunction caused by DM using auditory brainstem responses and auditory middle latency responses in mice...

BACKGROUND: Enhanced recovery pathways (ERPs) have been shown to aid in patient recovery and improve outcomes in many surgical settings. At present, there is limited data available regarding the use and feasibility of ERPs for patients undergoing microsurgical breast reconstruction. We sought to assess patient outcomes before and after the introduction of an ERP that was adopted by multiple surgeons at a single cancer center. METHODS: A multidisciplinary ERP was developed for patients undergoing deep inferior epigastric perforator (DIEP) or muscle-sparing free transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction...

The host defence against infection is an adaptive response in which several mechanisms are deployed to decrease the pathogen load, limit tissue injury and restore homeostasis. In the past few years new evidence has suggested that the ability of the immune system to limit the microbial burden - termed resistance - might not be the only defence mechanism. In fact, the capacity of the host to decrease its own susceptibility to inflammation- induced tissue damage - termed tolerance - might be as important as resistance in determining the outcome of the infection...

The key coagulation factor FVII, and its activated form FVIIa, present a major interest for their role at the initiation phase of blood coagulation, and because they can activate all blood coagulation cascade, through the extrinsic, but also the intrinsic pathway. Blood activation initiated through FVII is first presented, as it is understood nowadays. Measurement of FVII and FVIIa were of main interest for epidemiological studies, but FVIIa contribution to assay results was only deduced. The introduction of specific FVIIa assays, functional or immunoassays, allowed measuring directly FVIIa without any interference of non-activated FVII, or other coagulation factors or their activated forms...

We previously reported that embryonic motor cortical neurons transplanted immediately after lesions in the adult mouse motor cortex restored damaged motor cortical pathways. A critical barrier hindering application of transplantation strategies for a wide range of traumatic injuries is the determination of a suitable time window for therapeutic intervention. Here, we report that a one-week delay between the lesion and transplantation significantly enhances graft vascularization, survival and proliferation of grafted cells...

BACKGROUND AND OBJECTIVES: Venous thromboembolism (VTE) is a common cause of preventable harm. Perioperative thoracic epidural analgesia (TEA) presents a challenge to optimal VTE prophylaxis. Our primary aim was to characterize missed doses of VTE prophylaxis associated with epidural catheter placement and removal. Our secondary aim was to measure the effect of an enhanced recovery after surgery (ERAS) pathway on the rate of TEA-associated missed VTE prophylaxis. METHODS: We retrospectively reviewed a prospectively collected database of 1264 colorectal surgery patients at a single academic center...

Restoration is frequently aimed at the recovery of target species, but also influences the larger food web in which these species participate. Effects of restoration on this broader network of organisms can influence target species both directly and indirectly via changes in energy flow through food webs. To help incorporate these complexities into river restoration planning we constructed a model that links river food web dynamics to in-stream physical habitat and riparian vegetation conditions. We present an application of the model to the Methow River, Washington (USA), a location of on-going restoration aimed at recovering salmon...

: Auditory activity plays an important role in the development of the auditory system. Decreased activity can result from conductive hearing loss (CHL) associated with otitis media, which may lead to long-term perceptual deficits. The effects of CHL have been mainly studied at later stages of the auditory pathway, but early stages remain less examined. However, changes in early stages could be important because they would affect how information about sounds is conveyed to higher-order areas for further processing and localization...

Periprosthetic osteolysis remains the leading obstacle for total joint replacements. Primarily, it was thought that aseptic loosening is mainly caused by macrophage mediated inflammatory process arising from production of wear debris. The role of osteoclasts and its sequential bone resorption ability has been extensively studied, but little is known about impaired osteogenesis during osteolysis. In the current study, we have tried to delineate the regulatory mechanism of osteogenic signals by Ti particles in osteoprogenitor cells as well its participatory role in wear debris induced osteolysis...
