1Increased expression of tumor necrosis factor-a is associated with advanced colorectal cancer stages显示文摘AIM:To detect the expression of tumor necrosis factor-a(TNF-a)in colorectal cancer(CRC)cells among Saudi patients,and correlate its expression with clinical stages of cancer.METHODS:Archival tissue specimens were collected from 30 patients with CRC who had undergone surgical intervention at King Khalid University Hospital.Patient demographic information,including age and gender,tumor sites,and histological type of CRC,was recorded.To measure TNF-a m RNA expression in CRC,total RNA was extracted from tumor formalin-fixed,paraffinembedded,and adjacent normal tissues.Reverse transcription and reverse transcription polymerase chain reaction were performed.Colorectal tissue microarrays were constructed to investigate the protein expression of TNF-a by immunohistochemistry.RESULTS:The relative expression of TNF-a m RNA in colorectal cancer was significantly higher than that seen in adjacent normal colorectal tissue.High TNF-a gene expression was associated with StageⅢandⅣneoplasms when compared with earlier tumor stages(P=0.004).Eighty-three percent of patients(25/30)showed strong TNF-a positive staining,while only 10%(n=3/30)of patients showed weak staining,and 7%(n=2/30)were negative.We showed the presence of elevated TNF-a gene expression in cancer cells,which strongly correlated with advanced stages of tumor.CONCLUSION:High levels of TNF-a expression could be an independent diagnostic indicator of colorectal cancer,and targeting TNF-a might be a promising prognostic tool by assessment of the clinical stages of CRC.Omar A Al Obeed Khayal A Alkhayal Abdulmalik Al Sheikh Ahmad M Zubaidi Mansoor-Ali Vaali-Mohammed Robin Boushey James H Mckerrow Maha-Hamadien Abdulla 2014World Journal of Gastroenterology2014,20,48:8
2Serum MiRNA as Predictive and Prognosis Biomarker in Advanced Stage Non-small Cell Lung Cancer in Indonesia显示文摘Background and objective Lung cancer is the most common cause of death in men in the world and in Indonesia where nonsmall cell carcinoma lung cancer(NSCLC) constitutes 85% of all lung cancer cases. The high mortality rate is due to a poor prognosis and is often diagnosed as having advanced stages. If it is known at the initial stage, the prognosis of lung cancer will be better. Prognosis can be predicted with a marker of prognostic biology, one of which is micro RNA(mi RNA). This study aims to prove that serum mi RNA can be predictive biological marker and prognosis in NSCLC patients in Indonesia.Methods This study was cohort retrospective among 52 subjects in 'Dharmais' Hospital National Cancer Center. Sample was obtained from patients’ serum. Mi R-34, mi R-148, mi R-155 and mi R-222 serum are measured through Real-Time PCR(q PCR). Data were analyzed and interpreted with descriptive analysis, bivariate analysis(Mann Whitney-U for two type of variables or Kruskal-Wallis for more than two type of variables. Kaplan-Meier analysis was used to know association between characteristic which are sociodemographic, performance status, clinico-pathology, and survival rate in mi RNA expression. Results From this study, mi RNA expression: mi R-34(46.15%), mi R-148(23.08%), mi R-155(40.38%) and mi R-222(32.69%). Performance status score was statistically significant correlation with mi R-148(P=0.049) and mi R-222(P=0.018). High mi R-34 is associated with multiple M1 b metastatic type(P=0.020), cancer cell type(adenocarcinoma, P=0.009) and adenocarcinoma epidermal growth factor receptor(EGFR) mutation(negative, P=0.031). There was a significant correlation between the high mi R-222 as a poor prognosis in advanced stage NSCLC with M1 b metastasis(Median Survival/MS: 27 d, P=0.049) and positive EGFR mutations(MS: 74 d, P=0.049) and correlation of mi R-155 with adenocarcinoma(MS: 69 d, P=0.034) and positive EGFR gene mutations(MS: 58 d, P=0.023).Conclusion High mi R-34 expression in advanced stage NSCLC is the predictive factor for multiple metastatic, adenocarcinoma cell type and adenocarcinoma negative EGFR mutation. High expression of mi R-155 and mi R-222 are poor prognoses, especially high mi R-222 found in metastasis M1 b and positive EGFR mutation and mi R-155 found in adenocarcinoma and positive EGFR gene mutations. Further studies regarding correlation between mi RNA and survival rate are needed.Arif R HANAFI Achmad M JAYUSMAN Serafim ALFASUNU Ahmad H SADEWA Dibyo PRAMONO Didik S HERIYANTO Sofia M HARYANA 2020中国肺癌杂志2020,23,5:6
3Transradial approach for acute stroke intervention: technical procedure and clinical outcomes显示文摘background and purpose Radial artery catheterisation is an alternate route of access that has recently started to gain more widespread use for neuroendovascular procedures,including acute stroke intervention.In this small case series,we present our institution’s outcomes in patients undergoing acute stroke interventions via transradial access.Materials and methods We present a retrospective study of 15 patients who underwent acute stroke intervention via radial artery access.We analyse these patients’periprocedural and clinical outcomes after undergoing mechanical thrombectomy.results A total of 15 consecutive patients were included in the study(9 males and 6 females),and all patients were able to successfully undergo mechanical thrombectomy via radial artery access.The mean time of arterial puncture to reperfusion was 50±28 min(range:15-104).A TICI 2b/3 revascularisation was achieved in 13/15 patients(87%);a TICI 1 and TICI 2a outcome was achieved on the other two patients.One patient incurred an iatrogenic vessel dissection during the procedure.Eight of out 15 patients(53%)had favourable mRS(0-3)at the time of discharge from the hospital.Conclusion Radial artery catheterisation is technically feasible for performing acute stroke interventions with favourable time to revascularisation and good overall clinical outcomes.Omaditya Khanna Nikolaos Mouchtouris Ahmad Sweid Nohra Chalouhi Ritam Ghosh Fadi Al Saiegh Michael R Gooch Stavropoula Tjoumakaris Robert H Rosenwasser Victor Romo Pascal Jabbour 2020Stroke & Vascular Neurology2020,5,1:4
4Chemical composition, antioxidant activity and GC-MS analysis of juice and peel oil of grapefruit varieties cultivated in India显示文摘Citrus family especially Grapefruit,has attained considerable attention due to the presence of a number of essential components that have cardiovascular and anti-hypertensive properties.The juice and essential oil extracted from eight recently released grapefruit cultivars were used to study physicochemical and antioxidant properties.The total soluble solids(TSS),titratable acidity(TA) and pH of juice samples extracted from various grapefruit varieties differed significantly.The refractive index,specific gravity and optical rotation values for the oil varied from 1.473 to 1.396,0.863 to 0.847 and +93 to +86,respectively.The percent 2,2-diphenyl-1-picrylhydrazyl radical activity(% DPPH activity) and ferric reducing antioxidant power(FRAP) values for grapefruit juice and peel oil varied from 24.06 to 18.79,2.91 to 1.44 mmol g^–1 and 84.87 to 74.73,7.76 to 5.73 mmol g^-1,respectively.There were significant differences in physicochemical,antioxidant properties and volatile profiles of extracted juice and oil.The oil exhibited higher DPPH and FRAP values than the juice.Among different components identified which accounted for over 99% of the volatile fraction,limonene,myrcene,and benzopyran were major components in all oil samples.Shahnawaz Ahmed H S Rattanpal Khalid Gul Rouf Ahmad Dar Akash Sharma 2019Journal of Integrative Agriculture2019,18,7:3
5Physiological and biochemical appraisal for mulching and partial rhizosphere drying of cotton显示文摘Water is the main factor for the healthy life of plant.One of the main negative effects of climate change is the increasing scarcity of water that is lethal for plant.Globally,for water deficit regions(arid and semi-arid),drought is the main factor responsible for low production of agriculture,especially for cotton.Great efforts have been and are being made to find alternatives to water saving practices.This study aimed to examine the effects of partial rhizosphere drying(PRD,half of the root system irrigated at one event,and the other half irrigated in the next event,and so on)with and/or without various mulching treatments on physiological and biochemical traits of cotton.To explore this objective,we laid out experiments in completely randomized design with factorial arrangement in the Islamia University of Bahawalpur,Pakistan in 2016.Two factors included were four mulching treatments(M0,no mulching;M1,black plastic mulching;M2,wheat straw mulching;and M3,cotton sticks mulching)and two irrigation levels(I0,control(full irrigation);and I1,PRD).Fisher's analysis of variance among means of treatments was compared using least significant difference test at 5% probability level.Results revealed that the maximum plant height,leaf area,leaf gas exchange(photosynthetic rate and stomata conductance),chlorophyll,proline and total sugar contents,and enzyme activities were higher under M2 than under other three mulching treatments.As for irrigation levels,higher values of plant height,photosynthesis and water related parameters(leaf water potential,leaf osmotic potential,leaf turgor potential,etc.)were recorded.Contents of total sugar and proline and activities of antioxidant enzymes were significantly higher in PRD-treated plants than in control plants.It was concluded that combined application of PRD and mulching was more effective than the rest of the treatments used in the experiment.Similar study can be conducted in the field by applying irrigation water in alternate rows in semi-arid regions.Rashid IQBAL Muhammad A S RAZA Muhammad F SALEEM Imran H KHAN Salman AHMAD Muhammad S ZAHEER Muhammad U ASLAM Imran HAIDER 2019Journal of Arid Land2019,11,5:2
6The biology and demographic parameters of Aedes albopictus in northern peninsular Malaysia显示文摘Objective:To generate life table characteristics for the dengue vector Aedes albopictus(A. albopictus) under uncontrolled conditions,incorporating both the aquatic and the adult stages. Methods:Ten females derived from wild pupae were allowed to fully blood-feed on restrained mice.774 eggs were hatched in seasoned water.F1 larvae were followed for development until their F2 counterparts emerged as adults.Some population parameters were monitored(Fl) or estimated(F2).Results:A.albopictus exhibited increased fecundity and egg hatch success. Immature development was quick.Immature survival was high,with lowest rate in the pupal stage.Adult emergence was about 81%and sex ratio was close to 1:1.Generational mortality(K) was about 28%.A high proportion of females completed a reproductive cycle and the obtained parity rate was predicted to lead to higher fecundity in the next generation.Conclusios:It can be concluded that natural A.albopictus populations in Penang seem largely determined by quick development in combination with low immature loss and increased oviposition.H Nur Aida Hamady Dieng Abu Hassan Ahmad Tomomitsu Satho AT Nurita MR Che Salmah Fumio Miake B Norasmah 2011Asian Pacific Journal of Tropical Biomedicine2011,1,6:2

8In vitro larvicidal potential against Anopheles stephensi and antioxidative enzyme activities of Ginkgo biloba,Stevia rebaudiana and Parthenium hysterophorous显示文摘Objective:To investigate in vitro larvicidal and antioxidant enzymes potential of the medicinal plants Ginkgo biloba(G.biloba),Stevia rebaudiana(S.rebaudiana) and Parthenium hysterophorous(P.hysterophorous) against Anopheles stephensi(An.stephensi) 4th instars larvae. Methods:For evaluation of larvicidal potential,the ethanolic,methanolic and dichloromethane leaves extracts of three different plants were used in dose-dependent experiments in two media, while the antioxidant enzymes activities were investigated using four different methods viz., superoxide dismutase,peroxidase,ascorbate and catalase.Results:An.stephensi has developed resistance to various synthetic insecticides,making its control increasingly difficult.The comparative performance of ethanolic extracts(65%-90%) was found better than the methanolic extract(70%-87%) and dichloromethane extract(60%-70%).Among the three plants extracts tested in two media,S.rebaudiana exhibited higher larvicidal activity with LC50(24 h) in methanolic extract than P.hysterophorous and G.biloba.G.biloba and P.hysterophorous exhibited the strongest antioxidative enzymes activity and S.rebaudiana were less active and no significant difference was observed.Conclusions:These three plants exhibit larvicidal potential and can be further used for vector control alternative to synthetic insecticide due to eco-friendly and diseases control,furthermore these plant species have potent antioxidative enzyme activities, therefore,making them strong natural candidate particularly for diseases which are caused due to free radicals.Nisar Ahmad Hina Fazal Bilal H Abbasi Mazhar Iqbal 2011Asian Pacific Journal of Tropical Medicine2011,4,3:2
9Acute ischaemic stroke interventions: large vessel occlusion and beyond显示文摘Care for acute ischaemic stroke is one of the most rapidly evolving fields due to the robust outcomes achieved by mechanical thrombectomy.Large vessel occlusion(LVO)accounts for up to 38%of acute ischaemic stroke and comes with devastating outcomes for patients,families and society in the pre-intervention era.A paradigm shift and a breakthrough brought mechanical thrombectomy back into the spotlight for acute ischaemic stroke;this was because five randomised controlled trials from several countries concluded that mechanical thrombectomy for acute stroke offered overwhelming benefits.This review article will present a comprehensive overview of LVO management,techniques and devices used,and the future of stroke therapy.In addition,we review our institution experience of mechanical thrombectomy for posterior and distal circulation occlusion.Ahmad Sweid Batoul Hammoud Sunidhi Ramesh Daniella Wong Tyler D Alexander Joshua Harrison Weinberg Maureen Deprince Jaime Dougherty Dimitri Jean-Mickael Maamari Stavropoula Tjoumakaris Hekmat Zarzour Michael R Gooch Nabeel Herial Victor Romo David M Hasan Robert H Rosenwasser Pascal Jabbour 2020Stroke & Vascular Neurology2020,5,1:2
