1Long Non-coding RNAs in the Cytoplasm显示文摘An enormous amount of long non-coding RNAs(lnc RNAs) transcribed from eukaryotic genome are important regulators in different aspects of cellular events. Cytoplasm is the residence and the site of action for many lncRNAs. The cytoplasmic lncRNAs play indispensable roles with multiple molecular mechanisms in animal and human cells. In this review, we mainly talk about functions and the underlying mechanisms of lncRNAs in the cytoplasm. We highlight relatively well-studied examples of cytoplasmic lncRNAs for their roles in modulating mRNA stability,regulating m RNA translation, serving as competing endogenous RNAs, functioning as precursors of microRNAs, and mediating protein modifications. We also elaborate the perspectives of cytoplasmic lncRNA studies.Farooq Rashid Abdullah Shah Ge Shan 2016Genomics, Proteomics & Bioinformatics2016,14,2:21
2Risk factors for fever and sepsis after percutaneous nephrolithotomy显示文摘Objective:Percutaneous nephrolithotomy(PCNL)is commonly used in the management of large renal stones.Postoperative infections are one of the most common complications of this procedure.The present study is to determine and assess the factors that may increase the risk to develop fever and urinary sepsis after PCNL.Methods:A total of 60 patients(38 males and 22 females)with a mean age of 40.25 years enrolled in this study in Sulaimania Teaching Hospital.Patients had renal stone disease need operation with different socioeconomic status,body mass index and different type and size of stones were included in this study.Patients with preoperative positive urine culture and sensitivity were excluded.Preoperative investigations done for all patients.All Patients received prophylactic antibiotic gentamicin intravenously at the induction of anaesthesia.Renal pelvis urine sample were taken from all patients after puncturing the pelvicalyceal system and send for culture and sensitivity.Patients were monitored closely in the postoperative period for the development of fever and sepsis.Results:Mean duration of the operations was 77.08 min ranged 40e120 min.All patients had postoperative nephrostomy tube.Seventeen(28.33%)patients developed post PCNL fever and the statistically significant factors for post PCNL fever were diabetes mellitus(DM)(p Z 0.001),stone burden(p Z 0.001),number of the stones(p<0.001),degree of hydronephrosis(p Z 0.001),duration of the operation(p<0.001),residual stones(p Z 0.001)and number of tracts(p Z 0.038).Three(5.00%)patients developed post PCNL sepsis,and the statistically significant risk factors for post PCNL sepsis were duration of the operation(p Z 0.013)and intraoperative blood loss,postoperative drop in haemoglobin(HB)level(p Z 0.046).Conclusion:DM,staghorn stones,degree of hydronephrosis,duration of the operation and number of tracts are risk factors for post PCNL fever,while number of stones,intraoperative blood loss,duration of the operation and residual stones are risk factors for post PCNL sepsis.Aso Omer Rashid Saman Salih Fakhulddin 2016Asian Journal of Urology2016,3,2:21
3Indoleamine 2,3-dioxygenase: As a potential prognostic marker and immunotherapeutic target for hepatocellular carcinoma显示文摘Tumor cells induce an immunosuppressive microen-vironment which leads towards tumor immune escape. Understanding the intricacy of immunomodulation by tumor cells is essential for immunotherapy. Indoleamine 2,3-dioxygenase(IDO) is an immunosuppressive enzyme which mediates tumor immune escape in various cancers including hepatocellular carcinoma(HCC). IDO up-regulation in HCC may lead to recruitment of regulatory T-cells into tumor microenvironment and therefore inhibit local immune responses and promote metastasis. HCC associated fibroblasts stimulate natural killer cells dysfunction through prostaglandin E2 and subsequently IDO promotes favorable condition for tumor metastasis. IDO up-regulation induces immuno-suppression and may enhance the risk of hepatitis C virus and hepatitis B virus induced HCC. Therefore, IDO inhibitors as adjuvant therapeutic agents may have clinical implications in HCC. This review proposes future prospects of IDO not only as a therapeutic target but also as a prognostic marker for HCC.Kashif Asghar Asim Farooq Bilal Zulfiqar Muhammad Usman Rashid 2017World Journal of Gastroenterology2017,23,13:16
4A modified failure criterion for transversely isotropic rocks显示文摘A modified failure criterion is proposed to determine the strength of transversely isotropic rocks. Mechanical properties of some metamorphic and sedimentary rocks including gneiss, slate, marble, schist,shale, sandstone and limestone, which show transversely isotropic behavior, were taken into consideration. Afterward, introduced triaxial rock strength criterion was modified for transversely isotropic rocks.Through modification process an index was obtained that can be considered as a strength reduction parameter due to rock strength anisotropy. Comparison of the parameter with previous anisotropy indexes in literature showed reasonable results for the studied rock samples. The modified criterion was compared to modified Hoek-Brown and Ramamurthy criteria for different transversely isotropic rocks. It can be concluded that the modified failure criterion proposed in this study can be used for predicting the strength of transversely isotropic rocks.Omid Saeidi Vamegh Rasouli Rashid Geranmayeh Vaneghi Raoof Gholami Seyed Rahman Torabi 2014Geoscience Frontiers2014,5,2:16

7Chitosan based bioactive materials in tissue engineering applications-A review显示文摘In recent years,there have been increasingly rapid advances of using bioactive materials in tissue engineering applications.Bioactive materials constitute many different structures based upon ceramic,metallic or polymeric materials,and can elicit specific tissue responses.However,most of them are relatively brittle,stiff,and difficult to form into complex shapes.Hence,there has been a growing demand for preparing materials with tailored physical,biological,and mechanical properties,as well as predictable degradation behavior.Chitosan-based materials have been shown to be ideal bioactive materials due to their outstanding properties such as formability into different structures,and fabricability with a wide range of bioactive materials,in addition to their biocompatibility and biodegradability.This review highlights scientific findings concerning the use of innovative chitosan-based bioactive materials in the fields of tissue engineering,with an outlook into their future applications.It also covers latest developments in terms of constituents,fabrication technologies,structural,and bioactive properties of these materials that may represent an effective solution for tissue engineering materials,making them a realistic clinical alternative in the near future.Md.Minhajul Islam Md.Shahruzzaman Shanta Biswas Md.Nurus Sakib Taslim Ur Rashid 2020Bioactive Materials2020,5,1:15
8Lymphangiogenesis:A new player in cancer progression显示文摘Lymph node metastasis is the hallmark of colon cancer progression,and is considered one of the most important prognostic factors.Recently,there has been growing evidence that tumor lymphangiogenesis(formation of new lymphatic vessels) plays an important role in this process.Here,we review the latest f indings of the role of lymphangiogenesis in colorectal cancer progression,and discuss its clinical application as a biomarker and target for new therapy.Understanding the molecular pathways that regulate lymphangiogenesis is mandatory to pave the way for the development of new therapies for cancer.In the future,tailored treatments consisting of combinations of chemotherapy,other targeted therapies,and anti-lymphangiogenesis agents will hopefully improve patient outcomes.This progression to the clinic must be guided by new avenues of research,such as the identif ication of biomarkers that predict response to treatment.Masayuki Nagahashi Subramaniam Ramachandran Omar M Rashid Kazuaki Takabe 2010World Journal of Gastroenterology2010,16,32:14

11Impact of Nitrogen, Phosphorus and Potassium on Brown Planthopper and Tolerance of Its Host Rice Plants显示文摘The brown planthopper(BPH),Nilaparvata lugens(St?l),appeared as a devastating pest of rice in Asia. Experiments were conducted to study the effects of three nutrients,nitrogen(N),phosphorus(P) and potassium(K),on BPH and its host rice plants. Biochemical constituents of BPH and rice plants with varying nutrient levels at different growth stages,and changes in relative water content(RWC) of rice plants were determined in the laboratory. Feeding of BPH and the tolerance of rice plants to BPH with different nutrient levels were determined in the nethouse. Concentrations of N and P were found much higher in the BPH body than in its host rice plants,and this elemental mismatch is an inherent constraint on meeting nutritional requirements of BPH. Nitrogen was found as a more limiting element for BPH than other nutrients in rice plants. Application of N fertilizers to the rice plants increased the N concentrations both in rice plants and BPH while application of P and K fertilizers increased their concentrations in plant tissues only but not in BPH. Nitrogen application also increased the level of soluble proteins and decreased silicon content in rice plants,which resulted in increased feeding of BPH with sharp reduction of RWC in rice plants ultimately caused susceptible to the pest. P fertilization increased the concentration of P in rice plant tissues but not changed N,K,Si,free sugar and soluble protein contents,which indicated little importance of P to the feeding of BPH and tolerance of plant against BPH. K fertilization increased K content but reduced N,Si,free sugar and soluble protein contents in the plant tissues which resulted in the minimum reduction of RWC in rice plants after BPH feeding,thereby contributed to higher tolerance of rice plants to brown planthopper.Md Mamunur RASHID Mahbuba JAHAN Khandakar Shariful ISLAM 2016Rice science2016,23,3:12
12Application of community-based and integrated strategy to reduce malaria disease burden in southern Tanzania:the study protocol of China-UK-Tanzania pilot project on malaria control显示文摘Background:During the past six decades,remarkable success on malaria control has been made in China.The major experience could be shared with other malaria endemic countries including Tanzania with high malaria burden.Especially,China’s 1-3-7 model for malaria elimination is one of the most important refined experiences from many years’efforts and key innovation measures for malaria elimination in China.Methods:The China-UK-Tanzania pilot project on malaria control was implemented from April,2015 to June,2018,which was an operational research with two communities receiving the proposed interventions and two comparable communities serving as control sites.The World Health Organization'Test,Treat,Track'(WHO-T3)Initiative,which calls for every suspected case to receive a diagnostic test,every confirmed case to be treated,and for the disease to be tracked,was integrated with Chinese experiences on malaria control and elimination for exploration of a proper model tailored to the local settings.Application of China’s 1-3-7 model integrating with WHO-T3 initiative and local resources aiming at reducing the burden of malaria in terms of morbidity and mortality by 30%in the intervention communities in comparison with that at the baseline survey.Discussion:The China-UK-Tanzania pilot project on malaria control was that at China’s first pilot project on malaria control in Africa,exploring the feasibility of Chinese experiences by China-Africa collaboration,which is expected that the strategies and approaches used in this project could be potential for scaling up in Tanzania and African countries,and contribute to the acceleration of malaria control and elimination in Africa.Duoquan Wang Prosper Chaki Yeromin Mlacha Tegemeo Gavana Mihayo Gabriel Michael Rashid Khatibu Jun Feng Zheng-Bin Zhou Kang-Ming Lin Shang Xia He Yan Deus Ishengoma Susan Rumisha Sigbert Mkude Renata Mandike Frank Chacky Charles Dismasi Salim Abdulla Honorati Masanja Ning Xiao Xiao-Nong Zhou 2019Infectious Diseases of Poverty2019,8,1:12
13Extra-articular distal tibial fractures, is interlocking nailing an option? A prospective study of 147 cases显示文摘Purpose:Distal tibia fractures comprise about 7%-10% of lower extremity trauma.Because of the peculiarity of the soft tissue and subcutaneous location of the bone there are many controversies in the ideal treatment of distal tibia fractures especially extra articular pilon fractures.Plating is fraught with complications of wound dehiscence and infection.There are limited studies which document outcomes in such cases using intramedullary interlocking nail.We intend to study the outcome and complications of extra articular distal tibial fractures treated with interlocking nailing.Methods:This is a prospective study conducted in a tertiary care orthopaedic hospital in southern India.There are 147 patients of distal tibia extra-articular fractures managed by IM nailing with follow up of more than one year were included in this study.Only cases with fresh injury (less than 1 week),fracture below the isthmus,closed and open Gustilo Anderson type 1 and 2 fractures were included in the study.Patients were reviewed at 3,6,12 and 24 weeks after surgery and thereafter at one year and were assessed for clinical and radiological signs of healing,any complications,time to union and functional outcome.Results:There were 102 males and 45 females (male/female ratio is 2.3∶1) with a mean age of 38.96 (range 23-65) years.According to AO classification,there were 78 cases (53.06%) of 43-A1,39 cases (26.53%) of 43-A2 and 30 cases of 43-A3 constituting 20.40%.The fracture united in all the patients at an average of 18 weeks (range 16-22 weeks),none of the patient in our series had a delayed or non-union.Two patients (1.47%) had the fracture united in mild valgus but it was well within the acceptable limits (<5°).The functional outcome was assessed in all the patients at final follow up using Olerud and Molander score all the patients fared an excellent to good score,there were no cases with poor score.Conclusion:Intramedullary nailing is a viable option to treat distal tibial fractures with excellent outcome.Wound complications related to plating can be avoided but meticulous surgical technique is key to avoid malunion.PNVSV Prasad Amit Nemade Rashid Anjum Nilesh Joshi 2019Chinese Journal of Traumatology2019,22,2:11
14垂直方向磷素竞争对杉木根系生长及生物量分配的影响显示文摘针对自然环境中有效磷养分主要分布于土壤表层而容易导致植物根系激烈竞争的问题,选择同一杉木(Cunninghamia lanceolata)无性系幼苗为研究对象,采用水平方向空间狭小而垂直方向空间大的室内盆栽模拟装置,以单株种植为对照,构建双株种植的竞争处理,通过设置3个供磷水平:不供磷处理(0 mg/kg KH_2PO_4)、低磷处理(6 mg/kg KH_2PO_4)和正常供磷处理(12 mg/kg KH_2PO_4),采用破坏性试验方式收获,分别在试验的前期(50 d)、中期(100 d)和后期(150 d)测定不同处理条件下杉木幼苗根系生物量与根系形态的变化,研究邻株杉木根系在垂直方向上对有限磷素资源的竞争策略。结果表明:竞争处理和供磷水平对杉木幼苗根系长度、平均直径等形态指标的影响存在交互作用(P<0.05),对杉木幼苗生物量分配、比根长等指标的影响均不存在明显的交互作用(P>0.05)。竞争处理中杉木根系形态增量均明显高于非竞争处理的单株幼苗,且随着胁迫时间的增加,根系形态增量均呈现显著的上升趋势,其中在胁迫中期和后期的增量明显高于前期,且邻株竞争处理明显提高了杉木的比根长,提升了根系觅磷的能力;随着供磷水平的提高,根表面积和根体积增量大体上呈现先上升后下降的趋势。与非竞争处理相比,竞争条件下杉木地上部生物积累量差异不明显,而根系生物量、根冠比均低于非竞争处理的单株幼苗。许静静 李琦 吴文景 Rashid Muhammad Haroon U 马祥庆 吴鹏飞 2019生态学报2019,39,6:11
15Wheat straw pretreatment with KOH for enhancing biomethane production and fertilizer value in anaerobic digestion显示文摘Wheat straw biodegradability during anaerobic digestion was improved by treatment with potassium hydroxide(KOH)to decrease digestion time and enhance biomethane production and fertility value.KOH concentrations of1%(K1),3%(K2),6%(K3)and 9%(K4)were tested for wheat straw pretreatment at ambient temperature with a C:N ratio of 25:1.86% of total solids(TS),89% of volatile solids(VS)and 22% of lignocellulose,cellulose and hemicellulose(LCH)(22%)were decomposed effectively with the wheat straw pretreated by 6% KOH.Enhanced biogas production and cumulative biomethane yield of 258 ml·(g VS)^(-1)were obtained increased by 45% and 41%respectively,compared with untreated wheat straw.Pretreated wheat straw digestion also yielded a digestate with higher fertilizer values potassium(138%),calcium(22%)and magnesium(16%).These results show that TS,VS and LCH can be effectively removed from wheat straw pretreated with KOH,improving biodegradability biomethane production and fertilizer value.Muhammad Jaffar Yunzhi Pang Hairong Yuan Dexun Zou Yanping Liu Baoning Zhu Rashid Mustafa Korai Xiujin Li 2016Chinese Journal of Chemical Engineering2016,24,3:11
16Strength degradation of sandstone and granodiorite under uniaxial cyclic loading显示文摘Change in mechanical properties of rocks under static loading has been widely studied and documented.However, the response of rocks to cyclic loads is still a much-debated topic. Fatigue is the phenomenon when rocks under cyclic loading fail at much lower strength as compared to those subjected to the monotonic loading conditions. A few selected cored granodiorite and sandstone specimens have been subjected to uniaxial cyclic compression tests to obtain the unconfined fatigue strength and life. This study seeks to examine the effects of cyclic loading conditions, loading amplitude and applied stress level on the fatigue life of sandstone, as a soft rock, and granodiorite, as a hard rock, under uniaxial compression test. One aim of this study is to determine which of the loading conditions has a stronger effect on rock fatigue response. The fatigue response of hard rocks and soft rocks is also compared. It is shown that the loading amplitude is the most important factor affecting the cyclic response of the tested rocks. The more the loading amplitude, the shorter the fatigue life, and the greater the strength degradation. The granodiorite specimens showed more strength degradation compared to the sandstone specimens when subjected to cyclic loading. It is shown that failure modes of specimens under cyclic loadings are different from those under static loadings. More local cracks were observed under cyclic loadings especially for granodiorite rock specimens.Rashid Geranmayeh Vaneghi Behnam Ferdosi Achola D.Okoth Barnabas Kuek 2018Journal of Rock Mechanics and Geotechnical Engineering2018,10,1:11
