| 1 | Evaluation of inflammatory activity in Crohn's disease and ulcerative colitis显示文摘Crohn's disease and ulcerative colitis evolve with a relapsing and remitting course.Determination of inflammatory state is crucial for the assessment of disease activity and for tailoring therapy.However,no simple diagnostic test for monitoring intestinal inflammation is available.Noninvasive markers give only indirect assessments of disease activity.Histopathological or endoscopical examinations accurately assess inflammatory activity,but they are invasive,time consuming and expensive and therefore are unsuitable for routine use.Imaging procedures are not applicable for ulcerative colitis.The usefulness of ultrasound and Doppler imag-ing in assessing disease activity is still a matter of discussion for Crohn's disease,and an increased interest in computed tomography enterograph (CTE) has been seen,mainly because it can delineate the extent and severity of bowel wall inflammation,besides detecting extraluminal findings.Until now,the available data concerning the accuracy of magnetic resonance enterography in detecting disease activity is less than CTE.Due to this,clinical activity indices are still commonly used for both diseases. | Eduardo Garcia Vilela Henrique Osvaldo da Gama Torres Fabiana Paiva Martins Maria de Lourdes de Abreu Ferrari Marcella Menezes Andrade Aloísio Sales da Cunha | 2012 | World Journal of Gastroenterology2012，18，9： | 23 |
| 2 | Intranasal nerve growth factor bypasses the blood-brain barrier and affects spinal cord neurons in spinal cord injury显示文摘The purpose of this work was to investigate whether,by intranasal administration,the nerve growth factor bypasses the blood-brain barrier and turns over the spinal cord neurons and if such therapeutic approach could be of value in the treatment of spinal cord injury.Adult Sprague-Dawley rats with intact and injured spinal cord received daily intranasal nerve growth factor administration in both nostrils for 1 day or for 3 consecutive weeks.We found an increased content of nerve growth factor and enhanced expression of nerve growth factor receptor in the spinal cord 24 hours after a single intranasal administration of nerve growth factor in healthy rats,while daily treatment for 3 weeks in a model of spinal cord injury improved the deficits in locomotor behaviour and increased spinal content of both nerve growth factor and nerve growth factor receptors.These outcomes suggest that the intranasal nerve growth factor bypasses blood-brain barrier and affects spinal cord neurons in spinal cord injury.They also suggest exploiting the possible therapeutic role of intranasally delivered nerve growth factor for the neuroprotection of damaged spinal nerve cells. | Luigi Aloe Patrizia Bianchi Alberto De Bellis Marzia Soligo Maria Luisa Rocco | 2014 | Neural Regeneration Research2014，9，10： | 17 |
| 3 | Relationship between sonographically measured median nerve cross-sectional area and presence of peripheral neuropathy in diabetic subjects显示文摘BACKGROUND Neuropathy is a common complication of diabetes mellitus resulting from direct damage by hyperglycemia to the nerves and/or ischemia by microvascular injury to the endoneurial vessels which supply the nerves. Median nerve is one of the peripheral nerves commonly affected in diabetic neuropathy. The median nerve size has been studied in non-Nigerian diabetic populations. In attempt to contribute to existing literature, a study in a Nigerian population is needed.AIM To evaluate the cross-sectional area(CSA) of the median nerve using B-mode ultrasonography(USS) and the presence of peripheral neuropathy(PN) in a cohort of adult diabetic Nigerians.METHODS Demographic and anthropometric data of 85 adult diabetes mellitus(DM) and 85 age-and sex-matched apparently healthy control(HC) subjects were taken. A complete physical examination was performed on all study subjects to determine the presence of PN and modified Michigan Neuropathy Screening Instrument(MNSI) was used to grade its severity. Venous blood was taken from the study subjects for fasting lipid profile(FLP), fasting blood glucose(FBG) and glycated haemoglobin(HbA1 c) while their MN CSA was evaluated at a point 5 cm proximal to(5 cmCATL) and at the carpal tunnel(CATL) by high-resolution Bmode USS. Data was analysed using SPSS version 22.RESULTS The mean MN CSA was significantly thicker in DM subjects compared to the HC at 5 cmCATL(P < 0.01) and at the CATL(P < 0.01) on both sides. The presence of diabetic peripheral neuropathy(DPN) further increased the MN CSA at the CATL(P < 0.05) but not at 5 cmCATL(P > 0.05). However, the severity of DPN had no additional effect on MN CSA 5 cm proximal to and at the CATL. There was no significant association between MN CSA and duration of DM and glycemic control.CONCLUSION Thickening of the MN CSA at 5 cmCATL and CATL is seen in DM. Presence of DPN is associated with worse thickening of the MN CSA at the CATL but not at5 cmCATL. Severity of DPN, duration of DM, and glycemic control had no additional effect on the MN CSA. | Fredrick ANDrew Attah Christianah Mopelola Asaleye Adeleye Dorcas Omisore Babatope Ayodeji Kolawole Adeniyi Sunday Aderibigbe Mathew Alo | 2019 | World Journal of Diabetes2019，10，1： | 8 |
| 4 | Role of nitric oxide in the impairment of circular muscle contractility of distended, uninflamed mid-colon in TNBS-induced acute distal colitis in rats显示文摘AIM: To evaluate the role of nitric oxide (NO) in the motor disorders of the dilated uninflamed mid-colon (DUMC)from trinitrobenzene sulfonic acid (TNBS)-induced acute distal colitis in rats.METHODS: Colitis was induced in male Sprague-Dawley rats by a single intracolonic administration of TNBS.Control rats received an enema of 0.9% saline. The rats were killed 48 h after TNBS or saline administration.Macroscopic and histologic lesions of the colon were evaluated. Myeloperoxidase (MPO) and nitric oxide synthase (NOS) activity were measured on the colonic tissue. In TNBS rats, we evaluated spontaneous and evoked contractile activity in circular muscle strips derived from DUMC in comparison to the same colonic segment of control rats, both in the presence and in the absence of a non-selective NOS isoforms inhibitor N-nitro-Larginine (L-NNA). Pharmacological characterization of electric field stimulation (EFS)-evoked contractile responses was also performed.RESULTS: In TNBS rats, the distal colon showed severe histological lesions and a high MPO activity, while the DUMC exhibited normal histology and MPO activity.Constitutive NOS activity was similar in TNBS and control rats, whereas inducible NOS activity was significantly increased only in the injured distal colon of TNBS rats.Isometrically recorded mechanical activity of circular muscle strips from DUMC of TNBS rats showed a marked reduction of the force and frequency of spontaneous contractions compared to controls, as well as of the contractile responses to a contracting stimulus. In the presence of L-NNA, the contractile activity and responses displayed a significantly greater enhancement compared to controls. The pharmacological characterization of EFS contractile responses showed that a cooperative-like interaction between cholinergic muscarinic and tachykinergic neurokinin 1 and 2 receptors mediated transmission in DUMC of TNBS rats vs a simple additive interaction in controls.CONCLUSION: The results of this study show that, during TNBS-induced acute distal colitis, circular muscle intrinsic contractile mechanisms and possible enteric neural excitatory activity are inhibited in the distended uninflamed mid-colon. Suppression of NO synthesis markedly improves spontaneous and evokes muscle contractions, in spite of any evident change in local NO activity. | Luciano Onori Annalisa Aggio Simona D'Alo' Paola Muzi Maria Grazia Cifone Gabriella Mellillo Rachele Ciccocioppo Gennaro Taddei Giuseppe Frieri Giovanni Latella | 2005 | World Journal of Gastroenterology2005，11，36： | 7 |
| 5 | Tissue with high intelligence quotient Adipose-derived stem cells in neural regeneration显示文摘The aim of the present review is to highlight the possible neuroregenerative potential ofadipose-derived stem cells. The key property of stem cells is plasticity including self-renewal,multilineage differentiation, and migration, whereas the required property is transplantability. For along time, embryonic stem cells were thought to be the only source of pluripotency, a dogma that hasbeen challenged during the last decade. Today, an alternative option might be adipose-derived stemcells, as easily accessible, ethical and autologous cellular source. Recent knowledge ofadipobiology increasingly recognizes that adipose tissue is the major endo- and paracrine organ ofthe human body. Likewise, numerous neuropetides, neurotrophic factors, neurotransmitters,hypothalamic and steroid hormones and their receptors are shared by adipose tissue and brain.Accordingly, the regenerative potential of neuroprotective factor-secreting adipose-derived stemcells is outlined. Whether the possible benefits of adipose stem cell-based therapy may be mediatedvia cell transdifferentiation and/or paracrine mechanisms remains to further be evaluated. | George N.Chaldakov Marco Fiore Anton B.Tonchev Mariyana G.Hristova Vesselka Nikolova Luigi Aloe | 2009 | Neural Regeneration Research2009，4，12： | 5 |
| 6 | Automatic Detection of COVID-19 Infection Using Chest X-Ray Images Through Transfer Learning显示文摘The new coronavirus(COVID-19),declared by the World Health Organization as a pandemic,has infected more than 1 million people and killed more than 50 thousand.An infection caused by COVID-19 can develop into pneumonia,which can be detected by a chest X-ray exam and should be treated appropriately.In this work,we propose an automatic detection method for COVID-19 infection based on chest X-ray images.The datasets constructed for this study are composed of194 X-ray images of patients diagnosed with coronavirus and 194 X-ray images of healthy patients.Since few images of patients with COVID-19 are publicly available,we apply the concept of transfer learning for this task.We use different architectures of convolutional neural networks(CNNs)trained on Image Net,and adapt them to behave as feature extractors for the X-ray images.Then,the CNNs are combined with consolidated machine learning methods,such as k-Nearest Neighbor,Bayes,Random Forest,multilayer perceptron(MLP),and support vector machine(SVM).The results show that,for one of the datasets,the extractor-classifier pair with the best performance is the Mobile Net architecture with the SVM classifier using a linear kernel,which achieves an accuracy and an F1-score of 98.5%.For the other dataset,the best pair is Dense Net201 with MLP,achieving an accuracy and an F1-score of 95.6%.Thus,the proposed approach demonstrates efficiency in detecting COVID-19 in X-ray images. | Elene Firmeza Ohata Gabriel Maia Bezerra João Victor Souza das Chagas Aloísio Vieira Lira Neto Adriano Bessa Albuquerque Victor Hugo Cde Albuquerque Pedro Pedrosa Rebouças Filho | 2021 | IEEE/CAA Journal of Automatica Sinica2021，8，1： | 3 |
| 7 | Dietary approach in the treatment of nonalcoholic fatty liver disease显示文摘Nonalcoholic fatty liver disease(NAFLD) has been identified as one of the most prevalent chronic liver disease in adults and children populations. NAFLD is usually associated with the metabolic syndrome(MS), which is chiefly related to insulin resistance and its consequences. Insulin resistance has a crucial role in the pathogenesis of hepatic steatosis and potentially nonalcoholic steatohepatitis(NASH). Because of the contemporary epidemics of MS and obesity, the burden of NAFLD is also expected to rise. Unhealthy diets, such as the so-called western diet, are enriched in fructose, trans-fatty acids and saturated fat and seem to be associated with the development of NAFLD. In human studies, certain dietary sugars, particularly fructose, are used as a substrate for lipogenesis leading to hepatic fatty infiltration, inflammation, and possibly fibrosis. Other investigations have shown that fat consumption especially cholesterol and trans/saturated fatty acids are also steatogenic and seem to increase visceral adiposity. The identification of specific dietary components that favor the development of NASH could be important for the management of this disorder. This review focuses on the effects of different dietary approaches to prevent and treat NAFLD emphasizing the macronutrients and energy composition. | Silvia Marinho Ferolla Luciana Costa Silva Maria de Lourdes Abreu Ferrari Aloísio Sales da Cunha Flaviano dos Santos Martins Cláudia Alves Couto Teresa Cristina Abreu Ferrari | 2015 | World Journal of Hepatology2015，7，24： | 2 |

| 9 | Neurotrophic and metabotrophic potential of nerve growth factor and brain-derived neurotrophic factor: Linking cardiometabolic and neuropsychiatric diseases显示文摘One of biggest recent achievements of neurobiology is the study on neurotrophic factors. The neurotrophins are exciting examples of these factors. They belong to a family of proteins consisting of nerve growth factor(NGF), brain-derived neurotrophic factor(BDNF), neurotrophin-3(NT-3), NT-4/5, NT-6, and NT-7. Today, NGF and BDNF are well recognized to mediate a dizzying number of trophobiological effects, ranging from neurotrophic through immunotrophic and epitheliotrophic to metabotrophic effects. These are implicated in the pathogenesis of various diseases. In the same vein, recent studies in adipobiology reveal that this tissue is the body's largest endocrine and paracrine organ producing multiple signaling proteins collectively termed adipokines, with NGF and BDNF being also produced from adipose tissue. Altogether, neurobiology and adipobiology contribute to the improvement of our knowledge on diseases beyond obesity such as cardiometabolic(atherosclerosis, type 2 diabetes, and metabolic syndrome) and neuropsychiatric(e.g., Alzheimer's disease and depression) diseases. The present review updates evidence for(1) neurotrophic and metabotrophic potentials of NGF and BDNF linking the pathogenesis of these diseases, and(2) NGF- and BDNF-mediated effects in ampakines, NMDA receptor antagonists, antidepressants, selective deacetylase inhibitors, statins, peroxisome proliferator-activated receptor gamma agonists, and purinergic P2X3 receptor up-regulation. This may help to construct a novel paradigm in the field of translational pharmacology of neuro-metabotrophins, particularly NGF and BDNF. | Stanislav Yanev Luigi Aloe Marco Fiore George N Chaldakov | 2013 | World Journal of Pharmacology2013，2，4： | 2 |
| 10 | Towards curative therapy in gastric cancer:Faraway, so close!显示文摘Although recent diagnostic and therapeutic advances have substantially improved the survival of patients with gastric cancer(GC), the overall prognosis is still poor. Surgery is the only curative treatment and should be performed in experienced centers. Due to high relapse following surgery, complementary and systemic treatment aimed at eradicating micrometastasis should be performed in most cases. Cytotoxic treatments are effective in downstaging locally advanced cancer, but different sensitivities and toxicities probably exist in different GC subtypes. Current treatment protocols are based primarily on clinical data and histological features, but molecular biomarkers that would allow for the prediction of treatment responses are urgently needed. Understanding how host factors are responsible for inter-individual variability of drug response or toxicity will also contribute to the development of more effective and less toxic treatments. | Marília Cravo Catarina Fidalgo Rita Garrido Tania Rodrigues Gon?alo Luz Carolina Palmela Marta Santos Fábio Lopes Rui Maio | 2015 | World Journal of Gastroenterology2015，21，41： | 2 |
