| 1 | Osteoporosis and obesity: Role of Wnt pathway in human and murine models显示文摘Studies concerning the pathophysiological connection between obesity and osteoporosis are currently an intriguing area of research.Although the onset of these two diseases can occur in a different way,recent studies have shown that obesity and osteoporosis share common genetic and environmental factors.Despite being a risk factor for health,obesity has traditionally been considered positive to bone because of beneficial effect of mechanical loading,exerted by high body mass,on bone formation.However,contrasting studies have not achieved a clear consensus,suggesting instead that excessive fat mass derived from obesity condition may not protect against osteoporosis or,even worse,could be rather detrimental to bone.On the other hand,it is hitherto better established that,since adipocytes and osteoblasts are derived from a common mesenchymal stem cell precursor,molecules that lead to osteoblastogenesis inhibit adipogenesis and vice versa.Here we will discuss the role of the key molecules regulating adipocytes and osteoblasts differentiation,which are peroxisome proliferators activated receptor-γand Wnts,respectively.In particular,wewill focus on the role of both canonical and non-canonical Wnt signalling,involved in mesenchymal cell fate regulation.Moreover,at present there are no experimental data that relate any influence of the Wnt inhibitor Sclerostin to adipogenesis,although it is well known its role on bone metabolism.In addition,the most common pathological condition in which there is a simultaneous increase of adiposity and decrease of bone mass is menopause.Given that postmenopausal women have high Sclerostin level inversely associated with circulating estradiol level and since the sex hormone replacement therapy has proved to be effective in attenuating bone loss and reversing menopause-related obesity,we hypothesize that Sclerostin contribution in adipogenesis could be an active focus of research in the coming years. | Graziana Colaianni Giacomina Brunetti Maria Felicia Faienza Silvia Colucci Maria Grano | 2014 | World Journal of Orthopedics2014,5,3: | 19 |
| 2 | 胸苷酸合成酶和拓扑异构酶-1及Ki-67对伊立替康联合5-氟脲嘧啶治疗晚期大肠癌的预测价值显示文摘目的探讨胸苷酸合成酶(TS)、拓扑异构酶1(Topo1)和肿瘤增殖指标Ki67对伊立替康(CPT11)联合5氟脲嘧啶(5Fu)治疗晚期大肠癌患者的临床疗效和预后的预测价值。方法采用免疫组化方法检测了CPT11+5Fu一线治疗78例大肠癌患者的TS、Topo1和Ki67的表达,并与化疗疗效和患者的临床预后进行了分析。结果各检测指标的表达水平与临床疗效之间无关,但是临床预后不同。其中,TS低表达患者表现明显长的肿瘤进展时间(TTP,P<0.05)和存活期(OS,P<0.05);Ki67低表达也预示长的OS(P<0.05)。与单个指标相比较,两个指标的联合也不能预测临床疗效,但是对预后的判断作用明显提高。TS低表达、Ki67低表达以及TS和Ki67均低表达患者的中位TTP分别为9,8和17个月(P=0.02);TS低表达、Topo1低表达以及TS和Topo1均低表达患者的中位TTP分别为9,9和13个月(P=0.03);而Topo1低表达、Ki67低表达、Ki67和Topo1均低表达患者的中位TTP分别为8,9和11个月(P=0.05)。其中任何两个指标均低表达肿瘤的TTP和OS均明显长于高表达者(P<0.05)。结论TS、Topo1和Ki67不能预测大肠癌患者CPT11+5Fu的疗效,但对其临床预后有一定的预测作用。其中任何两个指标的联合,比单一指标对患者预后的预测价值明显提高。 | 徐建明 朱步东 Mangia Anita Simone Gianni Montemurro Severino Giuliani Francesco Maiello Evaristo Colucci Giuseppe Paradiso Angelo | 2005 | 中华肿瘤杂志2005,27,5: | 9 |
| 3 | Lansoprazole prevents experimental gastric injury induced by non-steroidal anti-inflammatory drugs through a reduction of mucosal oxidative damage显示文摘AIM: This study investigated the mechanisms of protection afforded by the proton pump inhibitor lansoprazole against gastric injury induced by different non-steroidal antiinflammatory drugs (NSAIDs) in rats.METHODS: Male Sprague-Dawley rats were orally treated with indomethacin (100 μmol/kg), diclofenac (60 μmol/kg),piroxicam (150 μmol/kg) or ketoprofen (150 μmol/kg).Thirty minutes before NSAIDs, animals were orally treated with lansoprazole 18 or 90 μmol/kg. Four hours after the end of treatments, the following parameters were assessed: gastric mucosal PGE2, malondialdehyde (MDA), myeloperoxidase (MPO) or non-proteic sulfhydryl compounds (GSH) levels; reverse transcription-polymerase chain reaction (RT-PCR) of mucosal COX-2 mRNA; gastric acid secretion in pylorus-ligated animals; in vitro effects of lansoprazole (1-300 μmol/L) on the oxidation of low density lipoproteins (LDLs) induced by copper sulphate.RESULTS: All NSAIDs elicited mucosal necrotic lesions which were associated with neutrophil infiltration and reduction of PGE2 levels. Increments of MPO and MDA contents, as well as a decrease in GSH levels were detected in the gastric mucosa of indomethacin- or piroxicam-treated animals. Indomethacin enhanced mucosal cyclooxygenase-2 expression, while not affecting cyclooxygenase-1. At the oral dose of 18 μmol/kg lansoprazole partly counteracted diclofenac-induced mucosal damage, whereas at 90 μmol/kg it markedly prevented injuries evoked by all test NSAIDs. Lansoprazole at 90 μmol/kg reversed also the effects of NSAIDs on MPO, MDA and GSH mucosal contents, without interfering with the decrease in PGE2 levels or indomethacin-induced cyclooxygenase-2 expression. However, both lansoprazole doses markedly inhibited acid secretion in pylorus-ligated rats. Lansoprazole concentration-dependently reduced the oxidation of LDLs in vitro.CONCLUSION: These results suggest that, besides the inhibition of acid secretion, lansoprazole protection against NSAID-induced gastric damage depends on a reduction in mucosal oxidative injury, which is also responsible for an increment of sulfhydryl radical bioavailability. It is also suggested that lansoprazole does not influence the downregulation of gastric prostaglandin production associated with NSAID treatment. | Corrado Blandizzi Matteo Fornai Rocchina Colucci Gianfranco Natale Valter Lubrano Cristina Vassalle Luca Antonioli Gloria Lazzeri Mario Del Tacca | 2005 | World Journal of Gastroenterology2005,11,26: | 9 |
| 4 | Intestinal epithelial barrier and neuromuscular compartment in health and disease显示文摘A number of digestive and extra-digestive disorders,including inflammatory bowel diseases,irritable bowel syndrome,intestinal infections,metabolic syndrome and neuropsychiatric disorders,share a set of clinical features at gastrointestinal level,such as infrequent bowel movements,abdominal distension,constipation and secretory dysfunctions.Several lines of evidence indicate that morphological and molecular changes in intestinal epithelial barrier and enteric neuromuscular compartment contribute to alterations of both bowel motor and secretory functions in digestive and extra-digestive diseases.The present review has been conceived to provide a comprehensive and critical overview of the available knowledge on the morphological and molecular changes occurring in intestinal epithelial barrier and enteric neuromuscular compartment in both digestive and extra-digestive diseases.In addition,our intent was to highlight whether these morphological and molecular alterations could represent a common path(or share some common features)driving the pathophysiology of bowel motor dysfunctions and related symptoms associated with digestive and extra-digestive disorders.This assessment might help to identify novel targets of potential usefulness to develop original pharmacological approaches for the therapeutic management of such disturbances. | Vanessa D’Antongiovanni Carolina Pellegrini Matteo Fornai Rocchina Colucci Corrado Blandizzi Luca Antonioli Nunzia Bernardini | 2020 | World Journal of Gastroenterology2020,26,14: | 6 |
| 5 | Accuracy of a predictive model for severe hepatic fibrosis or cirrhosis in chronic hepatitis C显示文摘AIM: To assess the accuracy of a model in diagnosing severe fibrosis/cirrhosis in chronic hepatitis C virus (HCV)infection.METHODS: The model, based on the sequential combination of the Bonacini score (BS: ALT/AST ratio,platelet count and INR) and ultrasonography liver surface characteristics, was applied to 176 patients with chronic HCV infection. Assuming a pre-test probability of 35%,the model defined four levels of post-test probability of severe fibrosis/cirrhosis: <10% (low), 10-74% (not diagnostic), 75-90% (high) and >90% (almost absolute).The predicted probabilities were compared with the observed patients' distribution according to the histology (METAVIR).RESULTS: Severe fibrosis/cirrhosis was found in 67 patients (38%). The model discriminated patients in three comparable groups: 34% with a very high (>90%)or low (<10%) probability of severe fibrosis, 33% with a probability ranging from 75% to 90%, and 33% with an uncertain diagnosis (I.e., a probability ranging from 10%to 74%). The observed frequency of severe fibrosis/cirrhosis was within the predefined ranges.CONCLUSION: The model can correctly identify67% of patients with a high (>75%) or low (<10%) probability of cirrhosis, leaving only 33% of the patients still requiring liver biopsy. | Agostino Colli Alice Colucci Silvia Paggi Mirella Fraquelli Sara Massironi Marco Andreoletti Vittorio Michela Dario Conte | 2005 | World Journal of Gastroenterology2005,11,46: | 2 |
| 6 | Biology and pathology of the uterine micro environ merit and its natural killer cells显示文摘Tissues are the new frontier of discoveries in immunology.Cells of the immune system are an integral part of tissue physiology and immunity.Determining how immune cells inhabit,housekeep,and defend gut,lung,brain,liver,uterus,and other organs helps revealing the intimate details of tissue physiology and may offer new therapeutic targets to treat pathologies.The uterine microenvironment modulates the development and function of innate lymphoid cells[ILC,largely represented by natural killer(NK)cells],macrophages,T cells,and dendritic cells.These immune cells,in turn,contribute to tissue homeostasis.Regulated by ovarian hormones,the human uterine mucosa(endometrium)undergoes ~400 monthly cycles of breakdown and regeneration from menarche to menopause,with its fibroblasts,glands,blood vessels,and immune cells remodeling the tissue into the transient decidua.Even more transformative changes occur upon blastocyst implantation.Before the placenta is formed,the endometrial glands feed the embryo by histiotrophic nutrition while the uterine spiral arteries are stripped of their endothelial layer and smooth muscle actin.This arterial remodeling is carried out by invading fetal trophoblast and maternal immune cells,chiefly uterine NK(uNK)cells,which also assist fetal growth.The tran sformed arteries no Ion ger resp ond to mater nal stimuli and meet the increasi ng dema nds of the growing fetus.This review focuses on how the everchanging uterine microenvironment affects uNK cells and how uNK cells regulate homeostasis of the decidua,placenta development,and fetal growth.Determining these pathways will help understand the causes of major pregnancy complications. | Fuyan Wang Anita Ellen Qualls Laia Marques-Fernandez Francesco Colucci | 2021 | Cellular & Molecular Immunology2021,18,9: | 2 |
| 7 | Rethinking bioequivalence and equivalence requirements of orally inhaled drug products显示文摘Orally inhaled drug products(OIPs),such as corticosteroids and bronchodilators,are at the forefront of asthma and chronic obstructive pulmonary disease treatments,two diseases that afflict worldwide populations.Introducing generics of these products is essential,as the pricing of these medications remain a barrier to adequate patient care.Currently,there is no consensus between regulatory bodies as to the bioequivalence and equivalence requirements of OIPs that are intended for local action in the lungs.This manuscript critically reviews these requirements and presents future directions for clinicians,scientists,and regulators to consider to optimize the development and approval of OIPs. | Dina Al-Numani Philippe Colucci Murray P.Ducharme | 2015 | Asian Journal of Pharmaceutical Sciences2015,10,6: | 2 |
