2Incorporating novelty and novel ecosystems into restoration planning and practice in the 21st century显示文摘Novelty pervades the biosphere.In some cases,potentially irreversible abiotic and/or biotic changes have led to the crossing of thresholds and thus the formation of“novel ecosystems.”Their widespread emergence(particularly on land)and the presence of continued environmental change challenge a traditional restoration goal of restoring an historical ecosystem.Instead,we argue that restoration could broaden its frame of reference to consider how novel ecosystems might be used to maintain global biodiversity and provide ecosystem services and,in doing so,save potentially wasted efforts in attempting to fulfil traditional goals.Here we explore this contention in more depth by addressing:Are novel ecosystems innovative planning or lowering the bar?We show that novel ecosystems were not innovative planning in their original conception.On the contrary,they were recognized as ecosystems that were recalcitrant to traditional restoration approaches,coupled with an awareness that they had arisen inadvertently through deliberate human activity,either on-or off-site.Their recalcitrance to traditional restoration suggests that alternative goals may exist for these ecosystems using sometimes innovative intervention.This management may include biodiversity conservation or restoration for ecological function.We elucidate the latter aspect with reference to an experiment in the wheatbelt of Western Australia—The Ridgefield Multiple Ecosystem Services Experiment—the design of which has been informed by ecological theory and the acceptance of novelty as an ecosystem component.Although novel ecosystems do provide opportunities to broaden restoration planning and practice,and ultimately maintain and conserve global biodiversity in this era of environmental change,they necessarily“lower the bar”in restoration if the bar is considered to be the historical ecosystem.However,in these times of flux,such a bar is increasingly untenable.Instead,careful and appropriate interventions are required at local,regional,and global scales.These interventions need to take history into account,use ecological and evolutionary theory to inform their design,and be mindful of valid concerns such as hubris.Careful interventions thus provide an opportunity for broadening restoration’s framework to focus on maintaining global biodiversity and delivering ecosystem services as well as the traditional goals of restoring historical ecosystems.Michael P Perring Rachel J Standish Richard J Hobbs 2013Ecological Processes2013,2,1:6
3Platelet-rich plasma for muscle injuries: A systematic review of the basic science literature显示文摘BACKGROUND Platelet-rich plasma(PRP) is an increasingly used biologic adjunct for muscle injuries, as it is thought to expedite healing. Despite its widespread use, little is known regarding the mechanisms by which PRP produces its efficacious effects in some patients.AIM To clarify the effects of PRP on muscular pathologies at the cellular and tissue levels by evaluating the basic science literature.METHODS A systematic review of PubMed/MEDLINE and EMBASE databases was performed using the Preferred Reporting Items for Systematic Reviews and MetaAnalyses(PRISMA) guidelines and checklist. Level III in vivo and in vitro studies examining PRP effects on muscles, myocytes and/or myoblasts were eligible for inclusion. Extracted data included PRP preparation methods and study results.RESULTS Twenty-three studies were included(15 in vivo, 6 in vitro, 2 in vitro/in vivo). Only one reported a complete PRP cytology(platelets, and red and white blood cell counts). Five in vitro studies reported increased cellular proliferation, four reported increased gene expression, and three reported increased cellular differentiation. Five in vivo studies reported increased gene expression, three reported superior muscle regeneration, and seven reported improved histological quality of muscular tissue.CONCLUSION The basic science literature on the use of PRP in muscle pathology demonstrates that PRP treatment confers several potentially beneficial effects on healing in comparison to controls. Future research is needed to determine optimal cytology,dosing, timing, and delivery methods of PRP for muscle pathologies.Kyle N Kunze Charles P Hannon Jared D Fialkoff Rachel M Frank Brian J Cole 2019World Journal of Orthopedics2019,10,7:6
4Rho A signaling and blood pressure: The consequence of failing to “Tone it Down”显示文摘Uncontrolled high blood pressure is a major risk factor for heart attack, stroke, and kidney failure and contributes to an estimated 25% of deaths worldwide. Despite numerous treatment options, estimates project that reasonable blood pressure(BP) control is achieved in only about half of hypertensive patients. Improvements in the detection and management of hypertension will undoubtedly be accomplished through a better understanding of the complex etiology of this disease and a more comprehensive inventory of the genes and genetic variants that influence BP regulation. Recent studies(primarily in pre-clinical models) indicate that the small GTPase Rho A and its downstream target, Rho kinase, play an important role in regulating BP homeostasis. Herein, we summarize the underlying mechanisms and highlight signaling pathways and regulators that impart tight spatial-temporal control of Rho A activity. We also discuss known allelic variations in the Rho A pathway and consider how these polymorphisms may affect genetic risk for hypertension and its clinical manifestations. Finally, we summarize the current(albeit limited) clinical data on the efficacy of targeting the Rho A pathway in hypertensive patients.Xue Bai Rachel Dee Kevin D Mangum Christopher P Mack Joan M Taylor 2016World Journal of Hypertension2016,6,1:3
5Para-aortic lymph node involvement should not be a contraindication to resection of pancreatic ductal adenocarcinoma显示文摘BACKGROUND Para-aortic lymph nodes(PALN)are found in the aortocaval groove and they are staged as metastatic disease if involved by pancreatic ductal adenocarcinoma(PDAC).The data in the literature is conflicting with some studies having associated PALN involvement with poor prognosis,while others not sharing the same results.PALN resection is not included in the standard lymphadenectomy during pancreatic resections as per the International Study Group for Pancreatic Surgery and there is no consensus on the management of these cases.AIM To investigate the prognostic significance of PALN metastases on the oncological outcomes after resection for PDAC.METHODS This is a retrospective cohort study of data retrieved from a prospectively maintained database on consecutive patients undergoing pancreatectomies for PDAC where PALN was sampled between 2011 and 2020.Statistical comparison of the data between PALN+and PALN-subgroups,survival analysis with the Kaplan-Meier method and risk analysis with univariable and multivariable time to event Cox regression analysis were performed,specifically assessing oncological outcomes such as median overall survival(OS)and disease-free survival(DFS).RESULTS 81 cases had PALN sampling and 17(21%)were positive.Pathological N stage was significantly different between PALN+and PALN-patients(P=0.005),while no difference was observed in any of the other characteristics.Preoperative imaging diagnosed PALN positivity in one case.OS and DFS were comparable between PALN+and PALN-patients with lymph node positive disease(OS:13.2 mo vs 18.8 mo,P=0.161;DFS:13 mo vs 16.4 mo,P=0.179).No difference in OS or DFS was identified between PALN positive and negative patients when they received chemotherapy either in the neoadjuvant or in the adjuvant setting(OS:23.4 mo vs 20.6 mo,P=0.192;DFS:23.9 mo vs 20.5 mo,P=0.718).On the contrary,when patients did not receive chemotherapy,PALN disease had substantially shorter OS(5.5 mo vs 14.2 mo;P=0.015)and DFS(4.4 mo vs 9.8 mo;P<0.001).PALN involvement was not identified as an independent predictor for OS after multivariable analysis,while it was for DFS doubling the risk of recurrence.CONCLUSION PALN involvement does not affect OS when patients complete the indicated treatment pathway for PDAC,surgery and chemotherapy,and should not be considered as a contraindication to resection.Rupaly Pande Shafiq Chughtai Manish Ahuja Rachel Brown David C Bartlett Bobby V Dasari Ravi Marudanayagam Darius Mirza Keith Roberts John Isaac Robert P Sutcliffe Nikolaos A Chatzizacharias 2022World Journal of Gastrointestinal Surgery2022,14,5:2
