| 7 | Spatio-temporal Fragmentation of Leisure Activities in Information Era: Empirical Evidence from Nanjing, China显示文摘Activity fragmentation provides a new approach for understanding the transformation of urban space and function in the information era. Numerous theoretical and empirical studies have been conducted on activity fragmentation, but few studies have focused on the fragmentation of leisure activities. This study was intended to extend the extant literature by: 1) analysing the spatio-temporal fragmentation of physical and virtual leisure activities by using a dataset collected in Nanjing, China, and 2) evaluating the reasons of leisure activity fragmentation, as well as the potential spatial effect of activity fragmentation. The results indicated that virtual leisure activities are more fragmented than physical leisure activities, but the fragmentation of physical and virtual leisure activities varies on weekday and weekend, as well as in various locations and urban districts. In addition, the results suggested that sociodemographic factors and information and communication technology(ICT) variables distinctly affect the fragmentation of leisure activities. Meanwhile, the fragmentation of virtual leisure activities may enhance the transformation of traditional urban space by reallocating leisure activity times and locations. | XI Guangliang ZHEN Feng Puel GILLES Fernandez VALERIE | 2017 | Chinese Geographical Science2017,27,1: | 8 |
| 8 | Diabetic heart disease:A clinical update显示文摘Diabetes mellitus(DM) significantly increases the risk of heart disease,and DMrelated healthcare expenditure is predominantly for the management of cardiovascular complications.Diabetic heart disease is a conglomeration of coronary artery disease(CAD),cardiac autonomic neuropathy(CAN),and diabetic cardiomyopathy(DCM).The Framingham study clearly showed a 2 to 4-fold excess risk of CAD in patients with DM.Pathogenic mechanisms,clinical presentation,and management options for DM-associated CAD are somewhat different from CAD among nondiabetics.Higher prevalence at a lower age and more aggressive disease in DM-associated CAD make diabetic individuals more vulnerable to premature death.Although common among diabetic individuals,CAN and DCM are often under-recognised and undiagnosed cardiac complications.Structural and functional alterations in the myocardial innervation related to uncontrolled diabetes result in damage to cardiac autonomic nerves,causing CAN.Similarly,damage to the cardiomyocytes from complex pathophysiological processes of uncontrolled DM results in DCM,a form of cardiomyopathy diagnosed in the absence of other causes for structural heart disease.Though optimal management of DM from early stages of the disease can reduce the risk of diabetic heart disease,it is often impractical in the real world due to many reasons.Therefore,it is imperative for every clinician involved in diabetes care to have a good understanding of the pathophysiology,clinical picture,diagnostic methods,and management of diabetes-related cardiac illness,to reduce morbidity and mortality among patients.This clinical review is to empower the global scientific fraternity with up-to-date knowledge on diabetic heart disease. | Jake Rajbhandari Cornelius James Fernandez Mayuri Agarwal Beverly Xin Yi Yeap Joseph M Pappachan | 2021 | World Journal of Diabetes2021,12,4: | 8 |

| 12 | Psychological aspects of diabetes care: Effecting behavioral change in patients显示文摘Patients with diabetes mellitus(DM) need psychological support throughout their life span from the time of diagnosis. The psychological make-up of the patients with DM play a central role in self-management behaviors. Without patient's adherence to the effective therapies, there would be persistent sub-optimal contro of diseases, increase diabetes-related complications,causing deterioration in quality of life, resulting in increased healthcare utilization and burden on healthcare systems. However, provision of psychosocial support is generally inadequate due to its challenging nature of needs and demands on the healthcare systems. This review article examines patient's psychological aspects in general, elaborates in particular about emotion effects on health, and emotion in relation to other psychological domains such as cognition, self-regulation,self-efficacy and behavior. Some descriptions are also provided on willpower, resilience, illness perception and proactive coping in relating execution of new behaviors,coping with future-oriented thinking and influences of illness perception on health-related behaviors. These psychological aspects are further discussed in relationto DM and interventions for patients with DM. Equipped with the understanding of the pertinent nature of psychology in patients with DM; and knowing the links between the psychological disorders, inflammation and cardiovascular outcomes would hopefully encourages healthcare professionals in giving due attention to the psychological needs of patients with DM. | Boon-How Chew Sazlina Shariff-Ghazali Aaron Fernandez | 2014 | World Journal of Diabetes2014,5,6: | 5 |
| 13 | Role of ATG16L,NOD2 and IL23R in Crohn's disease pathogenesis显示文摘Inflammatory bowel disease is a group of diseases that includes Crohn's disease (CD) and ulcerative colitis.CD is characterized as a chronic inflammatory disease of the gastrointestinal tract,ranging from the mouth to the anus.Although there are gross pathological and histological similarities between CD and Johne's disease of cattle,the cause of CD remains controversial.It is vital to understand fully the cause of this disease because it affects approximately 500 000 people in North America and Europe.It ranges from 27 to 48 cases per 100 000 people.There are many theories on the cause of CD ranging from possible association with environmental factors including microorganisms to imbalance in the intestinal normal flora of the patients.Regardless of the environmental trigger,there is strong evidence that a genetic disposition is a major key in acquiring CD.Many studies have proven the link between mutations in the ATG16L,NOD2/CARD15,IBD5,CTLA4,TNFSF15 and IL23R genes,and CD.The purpose of this review is to examine all genetic aspects and theories of CD,including up to date multiple population studies performed worldwide. | Saleh A Naser Melissa Arce Anam Khaja Marlene Fernandez Najih Naser Sammer Elwasila Saisathya Thanigachalam | 2012 | World Journal of Gastroenterology2012,18,5: | 5 |
| 14 | Erythropoietin modulates bone marrow stromal cell differentiation显示文摘Erythropoietin is essential for bone marrow erythropoiesis and erythropoietin receptor on non-erythroid cells including bone marrow stromal cells suggests systemic effects of erythropoietin. Tg6 mice with chronic erythropoietin overexpression have a high hematocrit, reduced trabecular and cortical bone and bone marrow adipocytes, and decreased bone morphogenic protein 2 driven ectopic bone and adipocyte formation. Erythropoietin treatment(1 200 IU·kg–1) for 10 days similarly exhibit increased hematocrit,reduced bone and bone marrow adipocytes without increased osteoclasts, and reduced bone morphogenic protein signaling in the bone marrow. Interestingly, endogenous erythropoietin is required for normal differentiation of bone marrow stromal cells to osteoblasts and bone marrow adipocytes.ΔEpoR_E mice with erythroid restricted erythropoietin receptor exhibit reduced trabecular bone, increased bone marrow adipocytes, and decreased bone morphogenic protein 2 ectopic bone formation. Erythropoietin treated ΔEpoR_E mice achieved hematocrit similar to wild-type mice without reduced bone, suggesting that bone reduction with erythropoietin treatment is associated with non-erythropoietic erythropoietin response. Bone marrow stromal cells from wild-type,Tg6, and ΔEpoR_E-mice were transplanted into immunodeficient mice to assess development into a bone/marrow organ. Like endogenous bone formation, Tg6 bone marrow cells exhibited reduced differentiation to bone and adipocytes indicating that high erythropoietin inhibits osteogenesis and adipogenesis, while ΔEpoR_E bone marrow cells formed ectopic bones with reduced trabecular regions and increased adipocytes, indicating that loss of erythropoietin signaling favors adipogenesis at the expense of osteogenesis. In summary, endogenous erythropoietin signaling regulates bone marrow stromal cell fate and aberrant erythropoietin levels result in their impaired differentiation. | Sukanya Suresh Luis Fernandez de Castro Soumyadeep Dey Pamela G.

| 15 | Role of colonoscopy in the diagnostic work-up of bowel endometriosis显示文摘AIM:To evaluate the accuracy of colonoscopy for the prediction of intestinal involvement in deep pelvic endometriosis.METHODS:This prospective observational study was performed between September 2011 and July 2014.Only women with both a clinical and imaging diagnosis of deep pelvic endometriosis were included.The study was approved by the local ethics committee and written informed consent was obtained in all cases.Both colonoscopy and laparoscopy were performed by expert surgeons with a high level of expertise with these techniques.Laparoscopy was performed within4 wk of colonoscopic examination.All hypothetical colonoscopy findings(eccentric wall thickening with or without surface nodularities and polypoid lesions with or without surface nodularities of endometriosis)were compared with laparoscopic and histological findings.We calculated the sensitivity,specificity,positive predictive value and negative predictive value for the presence of colonoscopic findings of intestinal endometriosis.RESULTS:A total of 174 consecutive women aged between 21-42 years with a diagnosis of deep pelvic endometriosis who underwent colonoscopy andsurgical intervention were included in our analysis.In 76 of the women(43.6%),intestinal endometrial implants were found at surgery and histopathological examination.Specifically,38 of the 76 lesions(50%)were characterized by the presence of serosal bowel nodules;28 of the 76 lesions(36.8%)reached the muscularis layer;8 of the 76 lesions(10.5%)reached the submucosa;and 2 of the 76 lesions(2.6%)reached the mucosa.Colonoscopic findings suggestive of intestinal endometriosis were detected in 7 of the174(4%)examinations.Colonoscopy failed to diagnose intestinal endometriosis in 70 of the 76 women(92.1%).A colonoscopic diagnosis of endometriosis was obtained in all cases of mucosal involvement,in 3of 8 cases(37.5%)of submucosal involvement,in no cases of muscularis layer involvement and in 1 of 38cases(2.6%)of serosa involvement.The sensitivity,specificity,positive predictive and negative predictive values of colonoscopy for the diagnosis of intestinal endometriosis were 7%,98%,85%and 58%,respectively.CONCLUSION:Being an invasive procedure,colonoscopy should not be routinely performed in the diagnostic work-up of bowel endometriosis. | Marco Milone Antonio Mollo Mario Musella Paola Maietta Loredana Maria Sosa Fernandez Olena Shatalova Alessandro Conforti Gianni Barone Giuseppe De Placido Francesco Milone | 2015 | World Journal of Gastroenterology2015,21,16: | 5 |
| 16 | Varicocele repair in severe oligozoospermia: A case report of post-operative azoospermia显示文摘Varicocele has been implicated as a cause in 35%-50% of patients with primary infertility and up to 81% of men with secondary infertility. Although a large number of reports have shown improvement in the semen parameters after correction of varicocele, other studies have suggested no benefit. We report the first case of azoospermia after surgery in a young infertile male patient with left-sided varicocele and severe oligozoospermia undergoing laparoscopic varicocelectomy. A pregnancy was only achieved with assisted reproductive technology because semen cryopreservation was performed before surgery. In the light of the above, the deterioration of sperm count after varicocele repair in patients with severe oligozoospermia could be due to irreversible impairment of spermatogenesis of such patients, together with the possible temporary damage of the surgical repair. This possible complication could therefore turn the severe oligozoospermia into an indication to perform cryopreservation before surgery, on both clinical and medico-legal grounds. Further research is needed before drawing definitive conclusions regarding the management of varicocele-related severe oligozoospermia. | Marco Milone Mario Musella Miguel Emilio Sosa Fernandez Paola Maietta Annarita Sasso Loredana Maria Sosa Fernandez Laura Virginia Sosa Fernandez Francesco Milone | 2014 | World Journal of Clinical Cases2014,2,4: | 4 |
| 17 | DIRECT NUMERICAL SIMULATIONS OF MULTIPHASE FLOWS显示文摘Direct numerical simulations have recently emerged as a viable tool to study finite Reynolds number multiphase flows. The approach parallels direct numerical simulations of turbulent flows, but the unsteady motion of a deformable phase boundary adds considerable complexity. Here, a front tracking method that has been used to study several multiphase flow problems is described. The Navier Stokes equations are solved by a finite difference/front tracking technique that allows the inclusion of fully deformable interfaces and surface tension, in addition to inertial and viscous effects. A parallel version of the method makes it possible to use large grids and resolve flows containing a few hundred bubbles. | G. Tryggvason A. Esmaeeli A. Fernandez J.
