1Metal Fabrication by Additive Manufacturing Using Laser and Electron Beam Melting Technologies显示文摘Selective laser melting (SLM) and electron beam melting (EBM) are relatively new rapid, additive manufac- turing technologies which can allow for the fabrication of complex, multi-functional metal or alloy monoliths by CAD-directed, selective melting of precursor powder beds. By altering the beam parameters and scan strategies, new and unusual, even non-equilibrium microstructures can be produced; including controlled microstructural architectures which ideally extend the contemporary materials science and engineering paradigm relating structure-properties-processing-performance. In this study, comparative examples for SLM and EBM fabricated components from pre-alloyed, atomized precursor powders are presented. These include Cu, Ti–6Al–4V, alloy 625 (a Ni-base superalloy), a Co-base superalloy, and 17-4 PH stainless steel. These systems are characterized by optical metallography, scanning and transmission electron microscopy, and X-ray diffraction.Lawrence E. Murr Sara M. Gaytan Diana A.

2Parallel Driving in CPSS:A Unified Approach for Transport Automation and Vehicle Intelligence显示文摘The emerging development of connected and automated vehicles imposes a significant challenge on current vehicle control and transportation systems. This paper proposes a novel unified approach, Parallel Driving, a cloud-based cyberphysical-social systems(CPSS) framework aiming at synergizing connected automated driving. This study first introduces the CPSS and ACP-based intelligent machine systems. Then the parallel driving is proposed in the cyber-physical-social space,considering interactions among vehicles, human drivers, and information. Within the framework, parallel testing, parallel learning and parallel reinforcement learning are developed and concisely reviewed. Development on intelligent horizon(iHorizon)and its applications are also presented towards parallel horizon.The proposed parallel driving offers an ample solution for achieving a smooth, safe and efficient cooperation among connected automated vehicles with different levels of automation in future road transportation systems.Fei-Yue Wang Nan-Ning Zheng Dongpu Cao Clara Marina Martinez Li Li Teng Liu 2017IEEE/CAA Journal of Automatica Sinica2017,4,4:41

6MicroRNAs as biomarkers of diabetic retinopathy and disease progression显示文摘Diabetes mellitus, together with its complications, has been increasing in prevalence worldwide. Its complications include cardiovascular disease(e.g., myocardial infarction, stroke), neuropathy, nephropathy, and eye complications(e.g., glaucoma, cataracts, retinopathy, and macular edema). In patients with either type 1 or type 2 diabetes mellitus, diabetic retinopathy is the leading cause of visual impairment or blindness. It is characterized by progressive changes in the retinal microvasculature. The progression from nonproliferative diabetic retinopathy to a more advanced stage of moderate to severe nonproliferative diabetic retinopathy and proliferative diabetic retinopathy occurs very quickly after diagnosis of mild nonproliferative diabetic retinopathy. The etiology of diabetic retinopathy is unclear, and present treatments have limited effectiveness. Currently diabetic retinopathy can only be diagnosed by a trained specialist, which reduces the population that can be examined. A screening biomarker of diabetic retinopathy with high sensitivity and specificity would aid considerably in identifying those individuals in need of clinical assessment and treatment. The majority of the studies reviewed identified specific microRNAs in blood serum/plasma able to distinguish diabetic patients with retinopathy from those without retinopathy and for the progresion of the disease from nonproliferative diabetic retinopathy to proliferative diabetic retinopathy. In addition,certain microRNAs in vitreous humor were dysregulated in proliferative diabetic retinopathy compared to controls. A very high percentage of patients with diabetic retinopathy develop Alzheimer’s disease. Thus, identifying diabetic retinopathy by measurement of suitable biomarkers would also enable better screening and treatment of those individuals at risk of Alzheimer’s disease.Bridget Martinez Philip V.

8Radiological diagnosis and staging of hilar cholangiocarcinoma显示文摘Hilar cholangiocarcinoma is a rare malignant tumor arising from the epithelium of the bile ducts.Surgery is still the only chance of potentially curative treatment in patients with perihilar cholangiocarcinoma.However,radical resection requires aggressive surgical strategies that should be tailored optimally according to the location,size and vascular invasion of the tumors.Accurate diagnosis and staging of these tumors is therefore critical for optimal treatment planning and for determining a prognosis.Multidetector computed tomography(MDCT),magnetic resonance imaging(MRI) and MR cholangiography are useful tools,both to diagnose and stage hilar cholangiocarcinoma.Modern imaging techniques allow accurate detection of the level of obstruction and the longitudinal and radial spread of the tumor.In addition,high-resolution MDCT and MR provide specific radiographic features to determine vascular involvement of anatomic structures,such as the hepatic artery or the portal vein,which are critical to decide the surgical strategy.Finally,radiological staging allows detection of patients with distant metastasis in the liver or peritoneum who will not benefit from a surgical approach.Carlos Valls Sandra Ruiz Laura Martinez David Leiva 2013World Journal of Gastrointestinal Oncology2013,5,7:21
9Identification of coastal wetlands of international importance for waterbirds:a review of China Coastal Waterbird Surveys 2005–2013显示文摘Background:China's coastal wetlands belong to some of the most threatened ecosystems worldwide.The loss and degradation of these wetlands seriously threaten waterbirds that depend on wetlands.Methods:The China Coastal Waterbird Census was organized by volunteer birdwatchers in China's coastal region.Waterbirds were surveyed synchronously once every month at 14 sites,as well as irregularly at a further 18 sites,between September 2005 and December 2013.Results:A total of 75 species of waterbirds met the 1 % population level Ramsar listing criterion at least once at one site.The number of birds of the following species accounted for over 20 % of the total flyway populations at a single site:Mute Swan(Cygnus olor),Siberia Crane(Grus leucogeranus),Far Eastern Oystercatcher(Haematopus osculans),Bar-tailed Godwit(Limosa lapponica),Spotted Greenshank(Tringa guttifer),Great Knot(Calidris tenuirostris),Spoon-billed Sandpiper(Calidris pygmeus),Saunders' s Gull(Larus saundersi),Relict Gull(Larus relictus),Great Cormorant(Phalacrocorax carbo),Eurasian Spoonbill(Platalea leucorodia),Black-faced Spoonbill(Platalea minor) and Dalmatian Pelican(Pelecanus crispus).A total of 26 sites supported at least one species of which their number met the1 % criterion.Forty-two species met the 1 % criterion in the Yellow River Delta,Shandong;29 at the Cangzhou coast,Hebei and 26 species at the Lianyungang coast,Jiangsu.Conclusions:The results highlight the international importance of China's coastal wetlands for waterbirds.This study also demonstrates that participation of local birdwatchers in waterbird surveys results in data that are invaluable not only for understanding the current status of waterbirds in China's coastal regions but also for waterbird conservation and management.Qingquan Bai Jianzhong Chen Zhihong Chen Guotai Dong Jiangtian Dong Wenxiao Dong Vivian Wing Kan Fu Yongxiang Han Gang Lu Jing Li Yang Liu Zhi Lin Derong Meng Jonathan Martinez Guanghui Ni Kai Shan Renjie Sun Suixing Tian Fengqin Wang Zhiwei Xu Yat-tung Yu Jin Yang Zhidong Yang Lin Zhang Ming Zhang Xiangwu Zeng 2015Chinese Birds2015,,3:20
10Partially defatted black soldier fly larva meal inclusion in piglet diets: effects on the growth performance, nutrient digestibility,blood profile, gut morphology and histological features显示文摘Background:The aim of this trial was to investigate the effects of different inclusion levels of a partially defatted black soldier fly (BSF,Hermetia illucens L.) larva meal on the growth performance,nutrient digestibility,blood profile,gut morphology and histological features of piglets.A total of 48 newly weaned piglets were individually weighed (initial body weight (IBW):6.1 ± 0.16 kg) and randomly allocated to 3 dietary treatments (4 boxes as replicates/treatment and 4 animals/box).BSF larva meal was included at increasing levels (0% [BSF0],5% [BSFS] and 10% [BSF10]) in isonitrogenous and isoenergetic diets formulated for two feeding phases:Ⅰ (from d 1 to d 23) and Ⅱ (from d 24 to d 61).The weight gain (WG),average daily gain (ADG),average daily feed intake (ADFI) and feed conversion ratio (FCR) were calculated for each feeding phase and for the whole trial.The haematochemical parameters and nutrient digestibility of the piglets were also evaluated.A total of 3 piglets per box were slaughtered on d 61 and the slaughtered piglets were submitted to morphometric investigations and histopathological examinations.Results:No overall significant differences were observed for growth performance (P > 0.05),except for the ADFI of phase Ⅱ,which showed a linear response to increasing BSF meal levels (P < 0.05,maximum for the BSF10 group).Dietary BSF meal inclusion did not significantly influence the blood profile,except as far as monocytes and neutrophils are concerned,and these showed a linear and quadratic response,respectively,to increasing BSF meal levels (P < 0.05,maximum for the BSF10 and BSF5 groups,respectively).On the other hand,the nutrient digestibility,gut morphology and histological features were not affected by dietary BSF meal inclusion (P > 0.05).Conclusions:The obtained results show that a partially defatted BSF larva meal can be used as a feed ingredient in diets for weaned piglets without negatively affecting their growth performance,nutrient digestibility,blood profile,gut morphology or histological features.Ilaria Biasato Manuela Renna Francesco Gai Sihem Dabbou Marco Meneguz Giovanni Perona Silvia Martinez Ana Cristina Barroeta Lajusticia Stefania Bergagna Luca Sardi Maria Teresa Capucchio Enrico Bressan Andrea Dama Achille Schiavone Laura Gasco 2019Journal of Animal Science and Biotechnology2019,10,3:19
11MicroRNAs as diagnostic and therapeutic tools for Alzheimer's disease: advances and limitations显示文摘Alzheimer's disease(AD) is the most common age-related, progressive neurodegenerative disease. It is characterized by memory loss and cognitive decline and responsible for most cases of dementia in the elderly. Late-onset or sporadic AD accounts for > 95% of cases, with age at onset > 65 years. Currently there are no drugs or other therapeutic agents available to prevent or delay the progression of AD. The cellular and molecular changes occurring in the brains of individuals with AD include accumulation of β-amyloid peptide and hyperphosphorylated tau protein, decrease of acetylcholine neurotransmitter, inflammation, and oxidative stress. Aggregation of β-amyloid peptide in extracellular plaques and the hyperphosphorylated tau protein in intracellular neurofibrillary tangles are characteristic of AD. A major challenge is identifying molecular biomarkers of the early-stage AD in patients as most studies have been performed with blood or brain tissue samples(postmortem) at late-stage AD. Subjects with mild cognitive impairment almost always have the neuropathologic features of AD with about 50% of mild cognitive impairment patients progressing to AD. They could provide important information about AD pathomechanism and potentially also highlight minimally or noninvasive, easy-to-access biomarkers. MicroRNAs are dysregulated in AD, and may facilitate the early detection of the disease and potentially the continual monitoring of disease progression and allow therapeutic interventions to be evaluated. Four recent reviews have been published of microRNAs in AD, each of which identified areas of weakness or limitations in the reported studies. Importantly, studies in the last three years have shown considerable progress in overcoming some of these limitations and identifying specific microRNAs as biomarkers for AD and mild cognitive impairment. Further large-scale human studies are warranted with less disparity in the study populations, and using an appropriate method to validate the findings.Bridget Martinez Philip V.Peplow 2019Neural Regeneration Research2019,14,2:18

13Neuroinflammation and oxidative stress act in concert to promote neurodegeneration in the diabetic retina and optic nerve:galectin-3 participation显示文摘Diabetes is a lifelong disease characterized by glucose metabolic imbalance,in which low insulin levels or impaired insulin signaling lead to hyperglycemic state.Within 20 years of diabetes progression,95%of patients will have diabetic retinopathy,the leading cause of visual defects in working-age people worldwide.Although diabetes is considered a microvascular disease,recent studies have shown that neurodegeneration precedes vascular changes within the diabetic visual system,albeit its mechanisms are still under investigation.Neuroinflammation and oxidative stress are intrinsically related phenomena,since macrophage/microglia and astrocytes are the main sources of reactive oxygen species during central nervous system chronic degenerative diseases,and both pathological processes are increased in the visual system during diabetes.The present review will focus on recent findings of the contribution of oxidative stress derived from neuroinflammation in the early neurodegenerative aspects of the diabetic visual system and their relationship with galectin-3.Henrique Rocha Mendonca Raul Carpi-Santos Karin da Costa Calaza Ana Maria Blanco Martinez 2020Neural Regeneration Research2020,15,4:16
14Laparoscopic gastric surgery for cancer: Where do we stand?显示文摘Gastric cancer poses a significant public health problem, especially in the Far East, due to its high incidence in these areas. Surgical treatment and guidelines have been markedly different in the West, but nowadays this debate is apparently coming to an end. Laparoscopic surgery has been employed in the surgical treatment of gastric cancer for two decades now, but with controversies about the extent of resection and lymphadenectomy. Despite these difficulties, the apparent advantages of the laparoscopic approach helped its implementation in early stage and distal gastric cancer, with an increase on the uptake for distal gastrectomy for more advanced disease and total gastrectomy. Nevertheless, there is no conclusive evidence about the laparoscopic approach yet. In this review article we present and analyse the current status of laparoscopic surgery in the treatment of gastric cancer.Pantelis T Antonakis Hutan Ashrafian Alberto Martinez Isla 2014World Journal of Gastroenterology2014,20,39:16

17Injection of bone marrow mesenchymal stem cells by intravenous or intraperitoneal routes is a viable alternative to spinal cord injury treatment in mice显示文摘In spite of advances in surgical care and rehabilitation,the consequences of spinal cord injury(SCI)ar still challenging.Several experimental therapeutic strategies have been studied in the SCI field,and recen advances have led to the development of therapies that may act on the inhibitory microenvironment.As sorted lineages of stem cells are considered a good treatment for SCI.This study investigated the effect o systemic transplantation of mesenchymal stem cells(MSCs)in a compressive SCI model.Here we presen results of the intraperitoneal route,which has not been used previously for MSC administration after comveI.WeafC57BL/6nt lmy atb spinal cord compression for 1 minute with a 30-g vascular clip.The animals were divided into five groups DMEM at 7 days after SCI),DMEM i.v.(intravenous injection of 500μL of DMEM at 7 days after SCI)The effects of MSCs transplantation in white matter sparing were analyzed by luxol fast blue staining.Th number of preserved fibers was counted in semithin sections stained with toluidine blue and the presenc of trophic factors was analyzed by immunohistochemistry.In addition,we analyzed the locomotor perfor mance with Basso Mouse Scale and Global Mobility Test.Our results showed white matter preservation and a larger number of preserved fibers in the MSC groups than in the DMEM groups.Furthermore,th MSC groups had higher levels of trophic factors(brain-derived neurotrophic factor,nerve growth factor neurotrophin-3 and neurotrophin-4)in the spinal cord and improved locomotor performance.Our result indicate that injection of MSCs by either intraperitoneal or intravenous routes results in beneficial out comes and can be elected as a choice for SCI treatment.Bruna dos Santos Ramalho FernANDa Martins de Almeida Conrado Mendonca Sales Silmara de Lima Ana Maria Blanco Martinez 2018Neural Regeneration Research2018,13,6:12
18Nutritional effects of the dietary inclusion of partially defatted Hermetia illucens larva meal in Muscovy duck显示文摘Background: The present work is aimed at evaluating the effect of different inclusion levels of a partially defatted black soldier fly(Hermetia illucens,L.;HI) larva meal for ducks.A total of 192 female 3-day-old Muscovy ducklings(Cairina moschata domestica,Canedins R71 L White,Grimaud Freres Selection,France) were divided into 4 groups,assigned 4 different dietary treatments(6 replicates/treatment and 8 birds/replicate) and reared from 3 to 50 days of age.HI larva meal was included at increasing levels(0,3%,6% and 9%,HI0,HI3,HI6 and HI9,respectively) in isonitrogenous and isoenergetic diets formulated for 3 feeding phases: starter(3–17 days of age),grower(18–38 days of age) and finisher(39–50 days of age).The growth performance and apparent total tract digestibility were evaluated during the trial using titanium dioxide as an inert marker(0.3% of inclusion).At 51 days of age,two birds per pen were slaughtered and histomorphological investigations were performed.Results: The live weight and average daily gain showed a quadratic response to increasing HI meal in the grower period(minimum corresponding to the HI6 group).No effects of dietary inclusion levels were observed for the daily feed intake or feed conversion ratio.The apparent dry matter and organic matter digestibility were not affected by the dietary treatment.A linear decrease was observed for the crude protein apparent digestibility in the starter period(minimum for the HI9 groups).The ether extract apparent digestibility increased linearly during the grower and finisher periods(minimum for the HI0 group).The morphometric indices were not influenced by the dietary treatments.Conclusions: The inclusion of up to 9% of HI partially defatted larva meal in the diet of ducks did not cause any effect on growth performance,as well as the apparent digestibility.Moreover,dietary HI inclusion preserved the physiological intestinal development.Marta Gariglio Sihem Dabbou Ilaria Biasato Maria Teresa Capucchio Elena Colombino Fuensanta Hernandez Josefa Madrid Silvia Martinez Francesco Gai Christian Caimi Sara Bellezza Oddon Marco Meneguz Angela Trocino Riccardo Vincenzi Laura Gasco Achille Schiavone 2019Journal of Animal Science and Biotechnology2019,10,3:12
19WJSC 6^(th) Anniversary Special Issues(2):Mesenchymal stem cells Neurotrauma and mesenchymal stem cells treatment:From experimental studies to clinical trials显示文摘Mesenchymal stem cell(MSC)therapy has attracted the attention of scientists and clinicians around the world.Basic and pre-clinical experimental studies have highlighted the positive effects of MSC treatment after spinal cord and peripheral nerve injury.These effects are believed to be due to their ability to differentiate into other cell lineages,modulate inflammatory and immunomodulatory responses,reduce cell apoptosis,secrete several neurotrophic factors and respond to tissue injury,among others.There are many pre-clinical studies on MSC treatment for spinal cord injury(SCI)and peripheral nerve injuries.However,the same is not true for clinical trials,particularly those concerned with nerve trauma,indicating the necessity of more well-constructed studies showing the benefits that cell therapy can provide for individuals suffering the consequences of nerve lesions.As for clinical trials for SCI treatment the results obtained so far are not as beneficial as those described in experimental studies.For these reasons basic and pre-clinical studies dealing with MSC therapy should emphasize the standardization of protocols that could be translated to the clinical set with consistent and positive outcomes.This review is based on pre-clinical studies and clinical trials available in the literature from 2010 until now.At the time of writing this article there were 43 and 36 pre-clinical and 19 and 1 clinical trials on injured spinal cord and peripheral nerves,respectively.Ana Maria Blanco Martinez Camila de Oliveira Goulart Bruna dos Santos Ramalho Júlia Teixeira Oliveira Fernanda Martins Almeida 2014World Journal of Stem Cells2014,6,2:11
