1Gastric juice for the diagnosis of H pylori infection in patients on proton pump inhibitors显示文摘AIM: To determine the efficacy of gastric juice polymerase chain reaction (PCR) for the detection of H pylori infection in comparison with histology and gastric antral biopsy PCR in patients on a proton pump inhibitor (PPI). METHODS: Eighty-five consecutive patients with dyspeptic symptoms were enrolled. Gastric biopsies for histology, PCR and gastric juice were collected at endoscopy for PCR of the H pylori urease C gene (ure C). Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accuracy, positive and negative likelihood ratio for PCR of gastric juice for the H pylori ure C gene was compared to histology and gastric antral biopsy H pylori ure C PCR in patients with and without PPI. RESULTS: Gastric juice PCR was positive in 66 (78%) patients. Histology showed H pylori associated gastritis in 57 (67%). Gastric biopsy PCR was positive in 72 (85%). In patients not taking PPI, the sensitivity, specificity, PPV, NPV, accuracy and positive and negative likelihood ratio for gastric juice PCR were 89%, 72%, 91%, 67%, 90%, 85%, 3.1 and 0.1 respectively. In patients on PPI these values were 86%, 100%%, 100%, 29%, 86%, 9.5 and 1.4, respectively. CONCLUSION: Gastric juice PCR for the diagnosis of H pylori infection has increased sensitivity compared to histology with PPI. The use of gastric juice PCR is recommended to confirm H pylori status in patients taking PPIs.Javed Yakoob Shahid Rasool Zaigham Abbas Wasim Jafri Shahab Abid Muhammad Islam Zubair Ahmad 2008World Journal of Gastroenterology2008,14,10:4

3Evaluation of biomarkers, genetic mutations, and epigenetic modifications in early diagnosis of pancreatic cancer显示文摘BACKGROUND Pancreatic cancer(PC)is one of the deadliest malignancies with an alarming mortality rate.Despite significant advancement in diagnostics and therapeutics,early diagnosis remains elusive causing poor prognosis,marred by mutations and epigenetic modifications in key genes which contribute to disease progression.AIM To evaluate the various biological tumor markers collectively for early diagnosis which could act as prognostic biomarkers and helps in future therapeutics of PC in Kashmir valley.METHODS A total of 50 confirmed PC cases were included in the study to evaluate the levels of carbohydrate antigen 19-9(CA 19-9),tissue polypeptide specific antigen(TPS),carcinoembryonic antigen(CEA),vascular endothelial growth factor-A(VEGF-A),and epidermal growth factor receptor(EGFR).Mutational analysis was performed to evaluate the mutations in Kirsten rat sarcoma(KRAS),Breast cancer type 2(BRCA-2),and deleted in pancreatic cancer-4(DPC-4)genes.However,epigenetic modifications(methylation of CpG islands)were performed in the promoter regions of cyclin-dependent kinase inhibitor 2A(p16;CDKN2A),MutL homolog 1(hMLH1),and Ras association domain-containing protein 1(RASSF1A)genes.RESULTS We found significantly elevated levels of biological markers CA 19-9(P≤0.05),TPS(P≤0.05),CEA(P≤0.001),and VEGF(P≤0.001).Molecular genetic analysis revealed that KRAS gene mutation is predominant in codon 12(16 subjects,P≤0.05),and 13(12 subjects,P≤0.05).However,we did not find a mutation in DPC-4(1203G>T)and BRCA-2(617delT)genes.Furthermore,epigenetic modification revealed that CpG methylation in 21(P≤0.05)and 4 subjects in the promoter regions of the p16 and hMLH1 gene,respectively.CONCLUSION In conclusion,CA 19-9,TPS,CEA,and VEGF levels were significantly elevated and collectively have potential as diagnostic and prognostic markers in PC.Global data of mutation in the KRAS gene commonly in codon 12 and rare in codon 13 could augment the predisposition towards PC.Additionally,methylation of the p16 gene could also modulate transcription of genes thereby increasing the predisposition and susceptibility towards PC.Bilal Rah Manzoor Ahmad Banday Gh Rasool Bhat Omar J Shah Humira Jeelani Fizalah Kawoosa Tahira Yousuf Dil Afroze 2021World Journal of Gastroenterology2021,27,36:2
4生物入侵过程中的植物-土壤反馈:一种入侵植物的凋落物分解对其本地近缘植物的影响显示文摘植物入侵可通过正或负的植物-土壤反馈效应改变土壤的生物和非生物性质,从而影响入侵栖息地的土壤理化性质。许多入侵物种的凋落物分解可增加土壤养分,降低本地植物多样性,并导致进一步的植物入侵。关于入侵植物凋落物在不同土壤类型及深度分解及反馈效应的研究依然很少。本研究旨在明确入侵植物南美蟛蜞菊(Sphagneticola trilobata)凋落物在不同土壤类型和不同土壤深度条件下的分解情况及其对本地近缘植物蟛蜞菊(S.calendulacea)生理生长的影响。将装有南美蟛蜞菊凋落物的尼龙袋加入到不同深度(即0、2、4和6 cm)的砂土、营养土和粘土中,经6个月的分解后,回收凋落物袋并计算分解速率,随后在凋落物分解处理后的土壤中种植本地蟛蜞菊,并在生长期结束时测量其生理生态指标。研究结果表明,所有处理土壤类型中,凋落物在土壤深度为2和4 cm处分解后显著增加了土壤养分,而对本地蟛蜞菊的叶片叶绿素、叶氮含量等生长指标表现为负效应。因此,入侵植物南美蟛蜞菊凋落物分解对土壤养分表现为正的反馈效应,而对本地植物蟛蜞菊的生长表现为负效应。我们的研究结果还表明,入侵植物的凋落物分解对土壤和本地物种的影响还因凋落物分解所在的土壤深度而显著不同。未来的研究应侧重于入侵栖息地中更多本地和入侵物种的植物-土壤反馈效应,以及更多土壤类型和土壤深度的入侵植物凋落物效应。Jianfan Sun Susan Rutherford Muhammad Saif Ullah Ikram Ullah Qaiser Javed Ghulam Rasool Muhammad Ajmal Ahmad Azeem Muhammad Junaid Nazir Daolin Du 2022Journal of Plant Ecology2022,15,3:2
5Recent Insights into Signaling Responses to Cope Drought Stress in Rice显示文摘Drought is one of the hot topics needing urgent attention in the current era of climate change.It massively disturbs the rice growth and productivity and is becoming a serious threat.The drought avoidance strategies in rice include stomatal closure,cellular adaptation and changes in root development.Moreover,the endogenous plant hormones(abscisic acid and jasmonic acid)and reactive oxygen species have paramount importance in drought tolerance in rice.The drought tolerance induces modification in biochemical,molecular and physiological properties of plants.At the molecular level,expression of several transcription-factors is modulated which further determine the activation of drought responsive gene families.Mitogen activated protein kinases and Ca signaling pathways initiate an array of signaling cascade for mediating the gene expression in rice.Approaches,conventional breeding methods combined with modern emerging techniques such as genetic engineering,to improve rice drought tolerance were discussed.This review provided recent insights into major regulatory factors against drought stress,signaling mechanisms and molecular engineering strategies(including conventional transgenic and recent genome editing approaches)to induce drought tolerance in rice.Muhammad Mahran ASLAM Muhammad Abdul Rehman RASHID Mohammad Aquil SIDDIQUI Muhammad Tahir KHAN Fozia FARHAT Shafquat YASMEEN Imtiaz Ahmad KHAN Shameem RAJA Fatima RASOOL Mahboob Ali SIAL ZHAO Yan 2022Rice science2022,29,2:2
6Efficacy of a traditional Persian medicine preparation for radiation-induced xerostomia:a randomized,open-label,active-controlled trial显示文摘BACKGROUND: Xerostomia is one of the most common side effects of radiation therapy among patients with head and neck cancers(HNC). However, conventional medicine lacks an effective treatment for radiation-induced xerostomia.OBJECTIVE: Synthesizing the traditional use of Alcea digitata and Malva sylvestris with their known beneficial effects from recent studies, we evaluated the efficacy of the herbs in the quality of life(QOL) of HNC patients with radiation-induced xerostomia.DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This study is a randomized, double-arm, open-label active-controlled clinical trial. We evaluated the effect of A. digitata and M. sylvestris on QOL of HNC patients with radiation-induced xerostomia compared with Hypozalix(artificial saliva). Patients were enrolled from the Imam Hossein Hospital's oncology clinic in Shahid Beheshti University of Medical Sciences, Tehran, Iran.MAIN OUTCOME MEASURES: Primary outcome measures in this trial were changes in patients' QOL assessed by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, Head and Neck Module(EORTC QLQ-H&N 35).RESULTS: Between-group analysis showed that the intervention group patients obtained significantly lower(better) total EORTC QLQ-H&N 35 scores as compared to the control group at the end of the intervention period(P = 0.007). Mean scores of dry mouth of EORTC QLQ-H&N 35 was also significantly lower(better) in the intervention group as compared to the control group(P = 0.017).CONCLUSION: Traditional Persian medicine preparation of hollyhocks and common mallow should be considered as a suitable treatment for xerostomia and improving QOL in HNC patients with radiation-induced xerostomia.TRIAL REGISTRATION: The trial was registered in Clinical Trials.gov with Identifier: NCT02854358.Ghazaleh Heydarirad Hossein Rezaeizadeh Rasool Choopani Seyed Hamdollah Mosavat Ahmad Ameri 2017Journal of Integrative Medicine2017,15,3:2
