1Circulating micro RNA, mi R-122 and mi R-221 signature in Egyptian patients with chronic hepatitis C related hepatocellular carcinoma显示文摘AIM: To explore the potential usefulness of serum miR-122 and miR-221 as non-invasive diagnostic markers of hepatitis C virus(HCV)-related hepatocellular carcinoma(HCC).METHODS: This prospective study was conducted on 90 adult patients of both sex with HCV-related chronic liver disease and chronic hepatitis C related HCC. In addition to the 10 healthy control individuals, patients were stratified into; interferon-na?ve chronic hepatitis C(CH)(n = 30), post-hepatitis C compensated cirrhosis(LC)(n = 30) and treatment-naive HCC(n = 30). All patients and controls underwent full clinical assessment and laboratory investigations in addition to the evaluation of the level of serum miR NA expression by RT-PCR.RESULTS: There was a significant fold change in serum mi RNA expression in the different patient groups when compared to normal controls; mi R-122 showed significant fold increasing in both CH and HCC and significant fold decrease in LC. On the other hand, mi R-221 showed significant fold elevation in both CH and LC groups and significant fold decrease in HCC group(P = 0.01). Comparing fold changes in miR NAs in HCC group vs non HCC group(CH and Cirrhosis), there was non-significant fold elevation in miR-122(P = 0.21) and significant fold decreasing in miR-221 in HCC vs non-HCC(P = 0.03). ROC curve analysis for miR-221 yielded 87% sensitivity and 40% specificity for the differentiation of HCC patients from non-HCC at a cutoff 1.82. CONCLUSION: Serum miR-221 has a strong potential to serve as one of the novel non-invasive biomarkers of HCC.Hassan El-Garem Ayman Ammer Hany Shehab Olfat Shaker Mohammed Anwer Wafaa El-Akel Heba Omar 2014World Journal of Hepatology2014,6,11:18
2Verification of Lactobacillus brevis tolerance to simulated gastric juice and the potential effects of postbiotic gamma-aminobutyric acid in streptozotocin-induced diabetic mice显示文摘The therapeutic effect of gamma-aminobutyric acid(GABA)on diabetes was spread as one of the alarming epidemics worldwide.The study aims to investigate the function of Lactobacillus brevis KLDS_(1.0727) and KLDS_(1.0373) strains as glutamic acid decarboxylase 65(GAD65)carriers capable of generating GABA by comparing in vitro free and freeze-dried models and GABA intervention in vivo.PCR amplification of gad and in vitro i.e.,(growth rate,viability at different pH,bile tolerance,and survivability in simulated gastric juice)were performed.In vivo experiments were conducted in 7 groups of C57BL/6J mice.Each group was injected with streptozotocin(Cont_(STZ),INSSTZ,LAC1_(STZ),LAC_(1MFDSTZ),LAC_(2STZ),LAC_(2MFDSTZ))daily except for the control(Cont).One group was injected with insulin(INSSTZ).The body weight and hyperglycemia in the blood were assessed weekly,post-euthanasia blood plasma parameters,insulin,and histological examination were evaluated.Results indicated L.brevis strains demonstrated a great tolerance to bile and simulated gastric juice in vitro(P<0.05).Cont_(STZ) had the highest average glucose level(6.84±6.46)mmol/L while INS_(STZ) expressed dramatically decreed in glucose level and displayed a significant decline in the average of weekly blood glucose(−5.74±3.08)mmol/L.The lowest body weight(ContSTZ)was(19.30±0.25)g.Based on the blood plasma analysis,L.brevis strains improved good cholesterol properties,liver and kidney functions,where most of these parameters fall within the average the reference range and prevent the development of symptoms of type 1 diabetes in vivo.As recommended,L.brevis should be commonly distributed as a postbiotic GABA in pharmaceutical and nutritional applications.Amro Abdelazez Heba Abdelmotaal Smith Etareri Evivie Maha Bikheet Rokayya Sami Hassan Mohamed Xiangchen Meng 2022Food Science and Human Wellness2022,11,1:1

6Pan-plastome approach empowers the assessment of genetic variation in cultivated Capsicum species显示文摘Pepper species(Capsicum spp.)are widely used as food,spice,decoration,and medicine.Despite the recent old-world culinary impact,more than 50 commercially recognized pod types have been recorded worldwide from three taxonomic complexes(A,B,and P).The current study aimed to apply a pan-plastome approach to resolve the plastomic boundaries among those complexes and identify effective loci for the taxonomical resolution and molecular identification of the studied species/varieties.High-resolution pan-plastomes of five species and two varieties were assembled and compared from 321 accessions.Phyloplastomic and network analyses clarified the taxonomic position of the studied species/varieties and revealed a pronounced number of accessions to be the rare and endemic species,C.galapagoense,that were mistakenly labeled as C.annuum var.glabriusculum among others.Similarly,some NCBIdeposited plastomes were clustered differently from their labels.The rpl23-trnI intergenic spacer contained a 44 bp tandem repeat that,in addition to other InDels,was capable of discriminating the investigated Capsicum species/varieties.The rps16-trnQ/rbcL-accD/ycf3-trnS gene set was determined to be sufficiently polymorphic to retrieve the complete phyloplastomic signal among the studied Capsicum spp.The pan-plastome approach was shown to be useful in resolving the taxonomical complexes,settling the incomplete lineage sorting conflict and developing a molecular marker set for Capsicum spp.identification.Mahmoud Magdy Lijun Ou Huiyang Yu Rong Chen Yuhong Zhou Heba Hassan Bihong Feng Nathan Taitano Esther van der Knaap Xuexiao Zou Feng Li Bo Ouyang 2019Horticulture Research2019,6,1:1

8Role of endoscopic ultrasound and cyst fluid tumor markers in diagnosis of pancreatic cystic lesions显示文摘BACKGROUND Pancreatic cystic lesions(PCLs) are common in clinical practice. The accurate classification and diagnosis of these lesions are crucial to avoid unnecessary treatment of benign lesions and missed opportunities for early treatment of potentially malignant lesions.AIM To evaluate the role of cyst fluid analysis of different tumor markers such as cancer antigens [e.g., cancer antigen(CA)19-9, CA72-4], carcinoembryonic antigen(CEA), serine protease inhibitor Kazal-type 1(SPINK1), interleukin 1 beta(IL1-β), vascular endothelial growth factor A(VEGF-A), and prostaglandin E2(PGE2)], amylase, and mucin stain in diagnosing pancreatic cysts and differentiating malignant from benign lesions.METHODS This study included 76 patients diagnosed with PCLs using different imaging modalities. All patients underwent endoscopic ultrasound(EUS) and EUS-fine needle aspiration(EUS-FNA) for characterization and sampling of different PCLs.RESULTS The mean age of studied patients was 47.4 ± 11.4 years, with a slight female predominance(59.2%). Mucin stain showed high statistical significance in predicting malignancy with a sensitivity of 87.1% and specificity of 95.56%. It also showed a positive predictive value and negative predictive value of 93.1% and 91.49%, respectively(P < 0.001). We found that positive mucin stain, cyst fluid glucose, SPINK1, amylase, and CEA levels had high statistical significance(P < 0.0001). In contrast, IL-1β, CA 72-4, VEGF-A, VEGFR2, and PGE2 did not show any statistical significance. Univariate regression analysis for prediction of malignancy in PCLs showed a statistically significant positive correlation with mural nodules, lymph nodes, cyst diameter, mucin stain, and cyst fluid CEA. Meanwhile, logistic multivariable regression analysis proved that mural nodules, mucin stain, and SPINK1 were independent predictors of malignancy in cystic pancreatic lesions.CONCLUSION EUS examination of cyst morphology with cytopathological analysis and cyst fluid analysis could improve the differentiation between malignant and benign pancreatic cysts. Also, CEA, glucose, and SPINK1 could be used as promising markers to predict malignant pancreatic cysts.Hussein Hassan Okasha Abeer Abdellatef Shaimaa Elkholy Mohamad-Sherif Mogawer Ayman Yosry Magdy Elserafy Eman Medhat Hanaa Khalaf Magdy Fouad Tamer Elbaz Ahmed Ramadan Mervat E Behiry Kerolis Y William Ghada Habib Mona Kaddah Haitham Abdel-Hamid Amr Abou-Elmagd Ahmed Galal Wael A Abbas Ahmed Youssef Altonbary Mahmoud El-Ansary Aml E Abdou Hani Haggag Tarek Ali Abdellah Mohamed A Elfeki Heba Ahmed Faheem Hani M Khattab Mervat El-Ansary Safia Beshir Mohamed El-Nady 2022World Journal of Gastrointestinal Endoscopy2022,14,6:1
9Gender Identification Using Marginalised Stacked Denoising Autoencoders on Twitter Data显示文摘Gender analysis of Twitter could reveal significant socio-cultural differ-ences between female and male users.Efforts had been made to analyze and auto-matically infer gender formerly for more commonly spoken languages’content,but,as we now know that limited work is being undertaken for Arabic.Most of the research works are done mainly for English and least amount of effort for non-English language.The study for Arabic demographic inference like gen-der is relatively uncommon for social networking users,especially for Twitter.Therefore,this study aims to design an optimal marginalized stacked denoising autoencoder for gender identification on Arabic Twitter(OMSDAE-GIAT)model.The presented OMSDAE-GIAR technique mainly concentrates on the identifica-tion and classification of gender exist in the Twitter data.To attain this,the OMS-DAE-GIAT model derives initial stages of data pre-processing and word embedding.Next,the MSDAE model is exploited for the identification of gender into two classes namely male and female.In the final stage,the OMSDAE-GIAT technique uses enhanced bat optimization algorithm(EBOA)for parameter tuning process,showing the novelty of our work.The performance validation of the OMSDAE-GIAT model is inspected against an Arabic corpus dataset and the results are measured under distinct metrics.The comparison study reported the enhanced performance of the OMSDAE-GIAT model over other recent approaches.Badriyya B.Al-onazi Mohamed K.Nour Hassan Alshamrani Mesfer Al Duhayyim Heba Mohsen Amgad Atta Abdelmageed Gouse Pasha Mohammed Abu Sarwar Zamani 2023Intelligent Automation & Soft Computing2023,,6:0
