| 1 | Relationship of MTHFR gene polymorphisms with renal and cardiac disease显示文摘AIM: To investigate the effects of different methylenetetrahydrofolate reductase(MTHFR) 677C>T gene polymorphism and hyperhomocysteinemia for the development of renal failure and cardiovascular events, which are controversial.METHODS: We challenged the relationship, if any, of MTHFR 677C>T and MTHFR 1298A>C polymorphisms with renal and heart function. The present article is a reappraisal of these concepts, investigating within a larger population, and including a subgroup of dialysis patients, if the two most common MTHFR polymorphisms, C677 T and A1298 C, as homozygous, heterozygous or with a compound heterozygous state, show different association with chronic renal failure requiring hemodialysis. MTHFR polymorphism could be a favorable evolutionary factor, i.e., a protective factor for many ominous conditions, like cancer and renal failure. A similar finding was reported in fatty liver disease in which it is suggested that MTHFR polymorphisms could have maintained and maintain their persistence by an heterozygosis advantage mechanism. We studied a total of 630 Italian Caucasian subject aged 54.60 ± 16.35 years, addressing to the increased hazard of hemodialysis, if any, according to the studied MTHFR genetic polymorphisms. RESULTS: A favorable association with normal renal function of MTHFR polymorphisms, and notably of MTHFR C677 T is present independently of the negative effects of left ventricular hypertrophy, increased IntraRenal arterial Resistance and hyperparathyroidism. CONCLUSION: MTHFR gene polymorphisms could have a protective role on renal function as suggested by their lower frequency among our dialysis patients in end-stage renal failure; differently, the association with left ventricular hypertrophy and reduced left ventricular relaxation suggest some type of indirect, or concurrent mechanism. | Francesca M Trovato Daniela Catalano Angela Ragusa G Fabio Martines Clara Pirri Maria Antonietta Buccheri Concetta Di Nora Guglielmo M Trovato | 2015 | World Journal of Nephrology2015，4，1： | 10 |
| 2 | Stem cell therapy for the treatment of Leydig cell dysfunction in primary hypogonadism显示文摘The production of testosterone occurs within the Leydig cells of the testes. When production fails at this level from either congenital, acquired, or systemic disorders,the result is primary hypogonadism. While numerous testosterone formulations have been developed, none are yet fully capable of replicating the physiological patterns of testosterone secretion. Multiple stem cell therapies to restore androgenic function of the testes are under investigation. Leydig cells derived from bone marrow, adipose tissue, umbilical cord, and the testes have shown promise for future therapy for primary hypogonadism. In particular, the discovery and utilization of a group of progenitor stem cells within the testes, known as stem Leydig cells(SLCs), has led not only to a better understanding of testicular development, but of treatment as well. When combining this with an understanding of the mechanisms that lead to Leydig cell dysfunction, researchers and physicians will be able to develop stem cell therapies that target the specific step in the steroidogenic process that is deficient. The current preclinical studies highlight the complex nature of regenerating this steroidogenic process and the problems remain unresolved. In summary, there appears to be two current directions for stem cell therapy in male primary hypogonadism. The first method involves differentiating adult Leydig cells from stem cells of various origins from bone marrow, adipose, or embryonic sources. The second method involves isolating, identifying, and transplanting stem Leydig cells into testicular tissue. Theoretically, in-vivo re-activation of SLCs in men with primary hypogonadism due to age would be another alternative method to treat hypogonadism while eliminating the need for transplantation. | Taylor C Peak Nora M Haney William Wang Kenneth J DeLay Wayne J Hellstrom | 2016 | World Journal of Stem Cells2016，8，10： | 5 |
| 3 | Aminoguanidine impedes human pancreatic tumor growth and metastasis development in nude mice显示文摘AIM:To study the action of aminoguanidine on pancreatic cancer xenografts in relation to cell proliferation,apoptosis,redox status and vascularization.METHODS:Xenografts of PANC-1 cells were developed in nude mice. The animals were separated into two groups:control and aminoguanidine treated. Tumor growth,survival and appearance of metastases were determined in vivo in both groups. Tumors were excised and ex vivo histochemical studies were performed. Cell growth was assessed by Ki-67 expression. Apoptosis was studied by intratumoral expression of B cell lymphoma-2 protein (Bcl-2) family proteins and Terminal deoxynucleotidyl transferase biotin-dUTP Nick End Labeling (Tunel). Redox status was evaluated by the expression of endothelial nitric oxide synthase (eNOS),catalase,copper-zinc superoxide dismutase (CuZnSOD),manganese superoxide dismutase (MnSOD) and glutathione peroxidase (GPx). Finally,vascularization was determined by Massons trichromic staining,and by VEGF and CD34 expression.RESULTS:Tumor volumes after 32 d of treatment by aminoguanidine (AG) were significantly lower than in control mice (P < 0.01). Median survival of AG mice was significantly greater than control animals (P < 0.01). The appearance of both homolateral and contralateral palpable metastases was significantly delayed in AG group. Apoptotic cells,intratumoral vascularization (trichromic stain) and the expression of Ki-67,Bax,eNOS,CD34,VEGF,catalase,CuZnSOD and MnSOD were diminished in AG treated mice (P < 0.01),while the expression of Bcl-2 and GPx did not change.CONCLUSION:The antitumoral action of aminoguanidine is associated with decreased cell proliferation,reduced angiogenesis,and reduced expression of antioxidant enzymes. | Nora A Mohamad Graciela P Cricco Lorena A Sambuco Máximo Croci Vanina A Medina Alicia S Gutiérrez Rosa M Bergoc Elena S Rivera Gabriela A Martín | 2009 | World Journal of Gastroenterology2009，15，9： | 3 |
| 4 | Differential expression of cell cycle regulators in HCV-infection and related hepatocellular carcinoma显示文摘AIM:To investigate cell cycle proteins in chronic hepatitis C virus infection in order to analyze their role in the process of hepatocyte transformation and to characterize their prognostic properties. METHODS:Subjects of the current study included 50 cases of chronic hepatitis C(CHC) without cirrhosis,30 cases of CHC with liver cirrhosis(LC) ,and 30 cases of hepatitis C-related hepatocellular carcinoma(HCC) admitted to the Department of Hepato-Gastroenterology,Theodor Bilharz Research Institute(TBRI) ,Giza,Egypt.Fifteen wedge liver biopsies,taken during laparoscopic cholecystectomy,were also included as normal controls.Laboratory investigations including urine and stool analysis,liver function tests and prothrombin concentration;serologic markers for viral hepatitis and ultrasonography were done for all cases of the study together with immunohistochemical analysis using primary antibodies against Cyclin D1,Cyclin E,p21,p27 and Rb/p105 proteins. RESULTS:Normal wedge liver biopsies didn't express Cyclin E or Rb/p105 immunostaining but show positive staining for Cyclin D1,p21 and p27.Cyclin D1 expressed nuclear staining that was sequentially increased from CHC to LC(P<0.01) to HCC(P<0.001) cases;meanwhile,Cyclin E revealed nuclear positivity only in the case of HCCs patients that was directly correlated to Rb/p105 immuno-reactivity.The expression of p21 and p27 was significantly increased in CHC and LC cases compared to normal controls and HCCs with no significant difference between well-and poorlydifferentiated tumors.p21 showed only a nuclear pattern of staining,while,p27 presented with either cytoplasmic and/or nuclear reactivity in all studied cases.Correlation analysis revealed a direct relation between Cyclin D1 and p21 in CHC cases(P<0.001) ,between Cyclin D1 and Cyclin E in HCCs(P<0.01);however,an inverserelationship was detected between Cyclin D1 and p21 or p27(P<0.001) and between p21 and Rb/p105(P<0.05) in HCCs. CONCLUSION:Upregulation of Cyclin D1 in CHC plays a vital role in the development and differentiation of HCC;while,Cyclin E may be a useful marker for monitoring tumor behavior.p21 and p27 can be used as predictive markers for HCC.Furthermore,higher expression of Rb/p105 as well as inverse relation with p21 and histologic grades suggests its important role in hepatic carcinogenesis. | Azza E El Bassiouny Mona M Nosseir Mona K Zoheiry Noha A Ameen Ahmed M Abdel-Hadi Ibrahim M Ibrahim Suher Zada Abdel-Hakeem Saad El-Deen Nora E El-Bassiouni | 2010 | World Journal of Hepatology2010，2，1： | 3 |

| 6 | Hamstring autograft utilization in reconstructing anterior cruciate ligament:Review of harvesting techniques,graft preparation,and different fixation methods显示文摘Rupture of the anterior cruciate ligament(ACL)is a common orthopedic injury.Various graft options are available for the reconstruction of ruptured ACL.Using the hamstring muscle as an autograft was first described in 1934,and it remains a commonly harvested graft for ACL reconstruction.Hamstring autografts can be harvested using the traditional anteromedial approach or the newer posteromedial technique.An isolated semitendinosus tendon can be used or combined with the gracilis tendon.There are numerous methods for graft fixation,such as intra-tunnel or extra-tunnel fixation.This comprehensive review discusses the different hamstring muscle harvesting techniques and graft preparation options and fixation methods.It provides a comprehensive overview for choosing the optimal surgical technique when treating patients. | Waleed Albishi Baraa Baltow Nora Albusayes Ameer A Sayed Hamza M Alrabai | 2022 | World Journal of Orthopedics2022，13，10： | 2 |
| 7 | Gastroesophageal reflux disease after diagnostic endoscopy in the clinical setting显示文摘AIM: To investigate the outcome of patients with symptoms of gastroesophageal reflux disease (GERD) referred for endoscopy at 2 and 6 mo post endoscopy. METHODS: Consecutive patients referred for upper endoscopy for assessment of GERD symptoms at two large metropolitan hospitals were invited to participate in a 6-mo non-interventional (observational) study.The two institutions are situated in geographically and socially disparate areas. Data collection was by selfcompletion of questionnaires including the patient assessment of upper gastrointestinal disorders symptoms severity and from hospital records. Endoscopic finding using the Los-Angeles classification, symptom severity and it's clinically relevant improvement as change of at least 25%, therapy and socio-demographic factors were assessed. RESULTS: Baseline data were available for 266 patients and 2-mo and 6-mo follow-up data for 128 and 108 patients respectively. At baseline, 128 patients had erosive and 138 non-erosive reflux disease. Allmost all patient had proton pump inhibitor (PPI) therapy in the past. Overall, patients with non-erosive GERD at the index endoscopy had significantly more severe symptoms as compared to patients with erosive or even complicated GERD while there was no difference with regard to medication. After 2 and 6 mo there was a small, but statistically significant improvement in symptom severity (7.02 ± 5.5 vs 5.9 ± 5.4 and 5.5 ± 5.4 respectively); however, the majority of patients continued to have symptoms (i.e. , after 6 mo 81% with GERD symptoms). Advantaged socioeconomic status as well as being unemployed was associated with greater improvement. CONCLUSION: The majority of GORD patients receive PPI therapy before being referred for endoscopy even though many have symptoms that do not sufficiently respond to PPI therapy. | Nora B Zschau Jane M Andrews Richard H Holloway Mark N Schoeman Kylie Lange William CE Tam Gerald J Holtmann | 2013 | World Journal of Gastroenterology2013，19，16： | 2 |
