1Therapeutic management options for stage Ⅲ non-small cell lung cancer显示文摘Lung cancer is the leading cause of cancer death worldwide.Majority of newly diagnosed lung cancers are non-small cell lung cancer(NSCLC), of which up to half are considered locally advanced at the time of diagnosis.Patients with locally advanced stage Ⅲ NSCLC consists of a heterogeneous population, making management for these patients complex.Surgery has long been the preferred local treatment for patients with resectable disease.For select patients, multimodality therapy involving systemic and radiation therapies in addition to surgery improves treatment outcomes compared to surgery alone.For patients with unresectable disease, concurrent chemoradiation is the preferred treatment.More recently, research into different chemotherapy agents, targeted therapies, radiation fractionation schedules, intensity-modulated radiotherapy, and proton therapy have shown promise to improve treatment outcomes and quality of life.The array of treatment approaches for locally advanced NSCLC is large and constantly evolving.An updated review of past and current literature for the roles of surgery, chemotherapeutic agents, radiation therapy, and targeted therapy for stage Ⅲ NSCLC patients are presented.Stephanie M Yoon Talha Shaikh Mark Hallman 2017World Journal of Clinical Oncology2017,8,1:32
2Hepatitis C virus in Pakistan:A systematic review of prevalence,genotypes and risk factors显示文摘In Pakistan more than 10 million people are living with Hepatitis C virus (HCV), with high morbidity and mortality. This article reviews the prevalence, genotypes and factors associated with HCV infection in the Pakistani population. A literature search was performed by using the keywords; HCV prevalence, genotypes and risk factors in a Pakistani population, in Pubmed, PakMediNet and Google scholar. Ninetyone different studies dating from 1994 to May 2009 were included in this study, and weighted mean and standard error of each population group was calculated. Percentage prevalence of HCV was 4.95% ± 0.53% in the general adult population, 1.72% ± 0.24% in the pediatric population and 3.64% ± 0.31% in a young population applying for recruitment, whereas a very high 57% ± 17.7% prevalence was observed in injecting drug users and 48.67% ± 1.75% in a multi-transfused population. Most prevalent genotype of HCV was 3a. HCV prevalence was moderate in the general population but very high in injecting drug users and multi-transfused populations. This data suggests that the major contributing factors towards increased HCV prevalence include unchecked blood transfusions and reuse of injection syringes. Awareness programs are required to decrease the future burden of HCV in the Pakistani population.Yasir Waheed Talha Shafi Sher Zaman Safi Ishtiaq Qadri 2009World Journal of Gastroenterology2009,15,45:12

4Plant-derived anticancer agents: A green anticancer approach显示文摘Cancer is a frightful disease and represents one of the biggest health-care issues for the human race and demands a proactive strategy for cure. Plants are reservoirs for novel chemical entities and provide a promising line for research on cancer. Hitherto, being effective, chemotherapy is accompanied by certain unbearable side effects. Nevertheless,plants and plant derived products is a revolutionizing field as these are Simple, safer, ecofriendly, low-cost, fast, and less toxic as compared with conventional treatment methods.Phytochemicals are selective in their functions and acts specifically on tumor cells without affecting normal cells. Carcinogenesis is complex phenomena that involves many signaling cascades. Phytochemicals are considered suitable candidates for anticancer drug development due to their pleiotropic actions on target events with multiple manners. The research is in progress for developing potential candidates(those can block or slow down the growth of cancer cells without any side effects) from these phytochemicals. Many phytochemicals and their derived analogs have been identified as potential candidates for anticancer therapy. Effort has been made through this comprehensive review to highlight the recent developments and milestones achieved in cancer therapies using phytomolecules with their mechanism of action on nuclear and cellular factors. Furthermore, drugs for cancer treatment and their limitations have also been discussed.Javed Iqbal Banzeer Ahsan Abbasi Tariq Mahmood Sobia Kanwal Barkat Ali Sayed Afzal Shah Ali Talha Khalil 2017Asian Pacific Journal of Tropical Biomedicine2017,7,12:8

9Phase field modeling for the morphological and microstructural evolution of metallic materials under environmental attack显示文摘The complex degradation of metallic materials in aggressive environments can result in morphological and microstructural changes.The phase-field(PF)method is an effective computational approach to understanding and predicting the morphology,phase change and/or transformation of materials.PF models are based on conserved and non-conserved field variables that represent each phase as a function of space and time coupled with time-dependent equations that describe the mechanisms.This report summarizes progress in the PF modeling of degradation of metallic materials in aqueous corrosion,hydrogen-assisted cracking,high-temperature metal oxidation in the gas phase and porous structure evolution with insights to future applications.Talha Qasim Ansari Haitao Huang San-Qiang Shi 2021npj Computational Materials2021,,1:3
10Reconfigurable intelligent surface-aided wireless communications: An overview显示文摘The reconfigurable intelligent surface(RIS)is an emerging technology,which will hopefully bring a new revolution in wireless communications.The RIS technology can be deployed in an indoor/outdoor environment to dynamically manipulate the propagation environment.The RIS consists of a large number of independently controllable passive elements,and these elements are involved in realizing high passive beamforming gain.Different from the conventional active phased antenna array,there is no dedicated radio-frequency(RF)chain installed at the RIS to perform complex signal processing operations.Therefore,it does not incur additional noise while retransmitting the incident wave,which is substantially a unique feature from the conventional wireless communication systems.Taking advantage of its working principle,RIS has been deployed in various practical scenarios.In this tutorial,at first we will review the latest advances in RIS,including the application scenarios such as the system and channel model,the information theoretic analysis,the physical realization and design,key signal processing techniques such as precoding and channel estimation,and prototyping.Finally,we discuss interesting future research problems for the RIS-aided communications.Muhammad Zain Siddiqi Talha Mir 2022Intelligent and Converged Networks2022,3,1:3
11Role of needle knife assisted ampullary biopsy in the diagnosis of periampullary carcinomaAbstractAIM:Tostudytheroleofneedleknifeassistedampul-显示文摘AIM:To study the role of needle knife assisted ampullary biopsy in the diagnosis of periampullary carcinoma.METHODS:In this study the authors retrospectively analyzed clinical records of patients with periampullary tumors diagnosed by ampullary biopsy taken after needle knife papillotomy in whom surface ampullary biopsies were non contributory.RESULTS:Between January 2008 and December 2010,38 patients with periampullary tumors were seen by us and initial side viewing endoscopy with surface biopsy from the papilla was positive for malignancy in 25 patients.Thirteen patients with a negative surface biopsy for malignancy underwent a repeat ampullary biopsy following needle knife papillotomy.There were 8(61.5%)males and 5(38.5%)females.The most common presenting symptom was jaundice(100%),followed by fever(46.2%),melena(38.5%),abdominal pain(30.8%)and weight loss(30.8%).All the patients had hyperbilirubinemia with a mean ± SD serum bilirubin of(11.2 ± 1.9)mg/dL(normal value <1 mg%)and the mean ± SD serum alkaline phosphatase was(288.0 ± 94.3)IU/L(normal value < 129 IU/L).Serum CA 19.9 level estimation was done in 11 patients;it was elevated(cut off value > 70.5 IU/L)in all of them with a median of 1200 IU/L(inter quartile range 274-3500).Side viewing endoscopy showed a bulky papilla in all of them.Adequate tissue was obtained in all of the 13 patients for histological evaluation;12 of the 13 patients were reported to have adenocarcinoma while one patient had adenoma.There were no complications from the needle knife papillotomy in any of the patients.CONCLUSION:Needle knife assisted ampullary biopsy appears to be a safe and effective diagnostic modality for periampullary carcinoma.Mohd Talha Noor Kim Vaiphei Birinder Nagi Kartar Singh 2011World Journal of Gastrointestinal Endoscopy2011,3,11:2
