1Effects of salt stress on rice growth, development characteristics, and the regulating ways: A review显示文摘Rice(Oryza sativa L.) is highly susceptible to the rhizosphere salinity than other cereals.High sensitivity has been observed,mainly at vegetative and reproductive stages in rice.It is the duty of plant physiologists to comprehend the growth,development,and physiological processes of rice plants under stress.This paper includes the overview of rice growth and developmental processes influenced by salt stress and the regulation pathways involved in these processes.It also includes the promising salt tolerance strategies,i.e.,genetic modification techniques,agronomic practices to improve rice growth,yield,and role of phytohormones and their management,especially inhibition of ethylene biosynthesis by using inhibitors 1-methylcyclopropene(1-MCP).Rice cultivation may be a first choice for improvement of salt tolerance through plant growth regulators and improved cultivation techniques.This study will significantly improve the understanding toward low rice grain yield and poor rice resistance under salt stress and will also stream scientific knowledge for effective utilization of salt affected soils by using different regulating ways.Sajid Hussain ZHANG Jun-hua ZHONG Chu ZHU Lian-feng CAO Xiao-chuang YU Sheng-miao Allen Bohr James HU Ji-jie JIN Qian-yu 2017Journal of Integrative Agriculture2017,16,11:19
2基质类型及烯效唑对不同秧龄晚稻机插质量和产量的影响显示文摘为明确基质类型及烯效唑对不同秧龄晚稻秧苗生理特征及本田期生长发育特性的影响,确定适宜晚稻机插育秧的基质类型、烯效唑浸种措施及秧龄,该研究以嘉58为供试晚稻品种,以2种代表性育秧介质(营养土和轻型无土育秧基质)为研究对象,采用2种(清水浸种和25 mg/L烯效唑浸种)外源生长调控措施,阐明了不同育秧介质和烯效唑浸种对不同秧龄晚稻秧苗生理特征、机插质量的影响及调控技术。结果表明,随晚稻秧龄延长,秧苗地上部分干物质量显著增加,叶片SPAD值和根系活力先增加后降低;水稻全生育期延长,大田生育期缩短。采用烯效唑浸种可提高秧苗素质,浸种处理秧苗茎基宽约增加0.1~0.2 mm,株高显著降低,叶片SPAD值和根系活力显著提高。短秧龄条件下烯效唑浸种对秧块质量和机插质量影响较小,长秧龄条件下烯效唑浸种可有效提高成苗率和大田基本苗数,降低漏插率和伤秧率。采用营养土育秧时最适机插秧龄为18 d,轻型无土基质育秧适宜机插秧龄为18~24 d。秧龄大于24 d时,烯效唑浸种可提高营养土育秧晚稻有效穗数和每穗粒数,增加晚稻产量,且秧龄越长,烯效唑浸种的增产效果越显著。烯效唑浸种对轻型无土基质育秧的产量影响较小。采用轻型无土育秧基质培育机插晚稻秧苗,产量高于常规营养土处理,适宜晚稻机插育秧。研究结果可为提升晚稻种植机械化水平提供重要参考。张均华 林育炯 黄洁 白志刚 Sajid Hussain 朱练峰 曹小闯 金千瑜 2018农业工程学报2018,34,1:18
3Recent advances in gel polymer electrolyte for high-performance lithium batteries显示文摘Lithium batteries (LBs) have become increasingly important energy storage systems in our daily life. However, their practical applications are still severely plagued by the safety issues from liquid electrolyte, especially when the batteries are exposed to mechanical, thermal, or electrical abuse conditions. Gel polymer electrolytes (GPEs) are being considered as an effective solution to replace currently available organic liquid electrolyte for building safer LBs. This review provides recent advancements in GPEs applied for high-performance LBs. On the one hand, from the environmental and economic point of view, the skeletons of GPEs changed from traditional polymer to renewable and degradable polymer. On the other hand, in addition to being as a component with good electrochemical and physical characterizations, the GPEs also need to provide some functions for addressing the concerns of lithium (Li) dendrites, unstable cathode electrolyte interface, dissolution and migration of transition metal ions,'shuttle effect' of polysulfides, and so on. Finally, to synchronously meet the challenges from the advanced cathode and Li metal anode, the bio-based GPEs with multi-functionality are proposed to develop high-energy/powerdensity batteries in the future.Ming Zhu Jiaxin Wu Yue Wang Mingming Song Lei Long Sajid Hussain Siyal Xiaoping Yang Gang Sui 2019Journal of Energy Chemistry2019,28,10:17

5Systematic review and meta-analysis on the prophylactic role of non-steroidal anti-inflammatory drugs to prevent post-endoscopic retrograde cholangiopancreatography pancreatitis显示文摘AIM: To critically appraise the published randomized, controlled trials on the prophylactic effectiveness of the non-steroidal anti-inflammatory drugs(NSAIDs), in reducing the risk of post-endoscopic retrograde cholangiopancreatography(ERCP) pancreatitis. METHODS: A systematic literature search(MEDLINE, Embase and the Cochrane Library, from inception of the databases until May 2015) was conducted to identify randomized, clinical trials investigating the role of NSAIDs in reducing the risk of post-ERCP pancreatitis. Random effects model of the meta-analysis was carried out, and results were presented as odds ratios(OR) with corresponding 95%CI.RESULTS: Thirteen randomized controlled trials on 3378 patients were included in the final meta-analysis. There were 1718 patients in the NSAIDs group and 1660 patients in non-NSAIDs group undergoing ERCP. The use of NSAIDs(through rectal route or intramuscular route) was associated with the reduced risk of post-ERCP pancreatitis [OR, 0.52(0.38-0.72), P = 0.0001]. The use of pre-procedure NSAIDs was effective in reducing approximately 48% incidence of post-ERCP pancreatitis, number needed to treat were 16 with absolute risk reduction of 0.05. But the risk of post-ERCP pancreattis was reduced by 55% if NSAIDs were administered after procedure. Similarly, diclofenac was more effective(55%) prophylactic agent compared to indomethacin(41%).CONCLUSION: NSAIDs seem to have clinically proven advantage of reducing the risk of post-ERCP pancreatitis.Muhammad S Sajid Amir H Khawaja Mazin Sayegh Krishna K Singh Zinu Philipose 2015World Journal of Gastrointestinal Endoscopy2015,7,19:14
6Polymorphisms of MTHFR and susceptibility to oesophageal adenocarcinoma in a Caucasian United Kingdom population显示文摘AIM:To identify if methylene tetra-hydrofolatereductase(MTHFR)C677T polymorphisms are associated with oesophageal adenocarcnomas in a Caucasian population and to test whether folic acid and homocysteine levels are linked with cancer risk.METHODS:A case control study comprising of 58 non cancer and 48 cancer patients,MTHFR C667T genotyping was made and serum folate,homocysteine and vitamin B12 levels were made.Tumour stage,differentiation and survival was recorded.A P value of less than0.05 was taken to be significant.Theχ2 used to compare discrete variables and the Mantel-Cox was used to compare survival.A P value less than 0.05 was deemed to be significant.RESULTS:MTHFR polymorphisms is associated with an increased risk of several cancers.A link between MTHFR C677T polymorphisms and oesophageal squamous cell carcinoma and gastric cardia adenocarcinoma has been demonstrated in at risk Chinese populations.In a Western European population the role of the MTHFR gene has not previously been investigated in the setting of oesophageal adenocarcinoma.No association between folic acid levels and cancer patients was found.The unstable MTHFR 667 TT genotype occurred in 11%cancers and 7%controls,but statistical significance was not reached,homocysteine levels and folic acid levels were not affected,cancer patients with TT genotype displayed a trend for a shorter survival 7 mo vs 20 mo.Serum vitamin B12 levels were higher in the cancer group.The MTHFR 667 TT genotype is much lower than previous population studies.CONCLUSION:We conclude that serum folic acid and MTHFR polymorphisms are not associated with an increased risk of oesophageal adenocarcinoma,although cancers with unstable TT genotype may indicate a more aggressive disease course.Richard Keld Manyi Thian Chia Hau Jamil Sajid Narveen Kumar Yeng Ang 2014World Journal of Gastroenterology2014,20,34:8
7Systematic review of oncological outcomes following laparoscopic vs open total mesorectal excision显示文摘AIM: To systematically analyze the randomized trials comparing the oncological and clinical effectiveness of laparoscopic total mesorectal excision(LTME) vs open total mesorectal excision(OTME) in the management of rectal cancer.METHODS: Published randomized, controlled trials comparing the oncological and clinical effectiveness of LTME vs OTME in the management of rectal cancer were retrieved from the standard electronic medical databases. The data of included randomized, controlled trials was extracted and then analyzed according to the principles of meta-analysis using RevMan? statistical software. The combined outcome of the binary variables was expressed as odds ratio(OR) and the combined outcome of the continuous variables waspresented in the form of standardized mean difference(SMD). RESULTS: Data from eleven randomized, controlled trials on 2143 patients were retrieved from the electronic databases. There was a trend towards the higher risk of surgical site infection(OR = 0.66; 95%CI: 0.44-1.00; z = 1.94; P < 0.05), higher risk of incomplete total mesorectal resection(OR = 0.62; 95%CI: 0.43-0.91; z = 2.49; P < 0.01) and prolonged length of hospital stay(SMD,-1.59; 95%CI:-0.86--0.25; z = 4.22; P < 0.00001) following OTME. However, the oncological outcomes like number of harvested lymph nodes, tumour recurrence and risk of positive resection margins were statistically similar in both groups. In addition, the clinical outcomes such as operative complications, anastomotic leak and all-cause mortality were comparable between both approaches of mesorectal excision.CONCLUSION: LTME appears to have clinically and oncologically measurable advantages over OTME in patients with primary rectal cancer in both short term and long term follow ups.Muhammad Shafique Sajid Adil Ahamd William FA Miles Mirza Khurrum Baig 2014World Journal of Gastrointestinal Endoscopy2014,6,5:7

9高效液相色谱-紫外检测法同时测定药物制剂及人体血清中的奥美沙坦酯和厄贝沙坦及氢氯噻嗪(英文)显示文摘A simple,selective,sensitive,precise,simultaneous high performance liquid chromatographic analysis of serum samples and commercial tablet formulation containing hydrochlorothiazide,olmesartan medoxomil and irbesartan are reported.Good chromatographic separation was achieved using a μ-Bondapak,C18 column(15 cm×4.6 mm,5 μm),and a mobile phase consisting of acetonitrile-0.2% acetic acid aqueous solution(50∶50,v/v)at a flow rate of 1.0 mL/min.The ultraviolet detector was set at a wavelength of 260 nm.Hydrochlorothiazide,olmesartan medoxomil,and irbesartan were eluted at 1.2,3.8,and 4.4 min,respectively.No extraneous materials were found to interfere.The method uses protein precipitation with acetonitrile for the preparation of serum sample.The linear ranges for hydrochlorothiazide,olmesartan medoxomil,and irbesartan were 6.25-18.75,20-60,and 75-225 ng/mL,respectively.The recoveries of hydrochlorothiazide,olmesartan medoxomil,and irbesartan in spiked samples were all greater than 98%,and their relative standard deviations were less than 2.0%.The limits of detection were 1,2,and 2 ng/mL for hydrochlorothiazide,olmesartan medoxomil,and irbesartan,respectively,and the limits of quantification were 3 ng/mL,which allow their determination at the expected serum concentration levels.SULTANA Najma ARAYNE M Saeed ALI S Shahid SAJID Shahnawaz 2008色谱2008,26,5:6
10Electrochemical CO_(2) reduction to C_(2+) products using Cu-based electrocatalysts:A review显示文摘With the disruptive carbon cycle being blamed for global warming,the plausible electrocatalytic CO_(2)reduction reaction(CO_(2)RR)to form valuable C_(2+)hydrocarbons and feedstock is becoming a hot topic.Cu-based electrocatalysts have been proven to be excellent CO_(2)RR alternatives for high energy value-added products in this regard.However,the selectivity of CO_(2)RR to form C_(2+)products via Cu-based catalysts suffers from a high overpotential,slow reaction kinetics,and low selectivity.This review attempts to discuss various cutting-edge strategies for understanding catalytic design such as Cu-based catalyst surface engineering,tuning Cu bandgap via alloying,nanocatalysis,and the effect of the electrolyte and pH on catalyst morphology.The most recent advances in in situ spectroscopy and computational techniques are summarized to fully comprehend reaction mechanisms,structural transformation/degradation mechanisms,and crystal facet loss with subsequent effects on catalyst activity.Furthermore,approaches for tuning Cu interactions are discussed from four key perspectives:single-atom catalysts,interfacial engineering,metal-organic frameworks,and polymer-incorporated materials,which provide new insights into the selectivity of C_(2+)products.Finally,major challenges are outlined,and potential prospects for the rational design of catalysts for robust CO_(2)RR are proposed.The integration of catalytic design with mechanistic understanding is a step forward in the promising advancement of CO_(2)RR technology for industrial applications.Touqeer Ahmad Shuang Liu Muhammad Sajid Ke Li Mohsin Ali Liang Liu Wei Chen 2022Nano Research Energy2022,1,2:5
11Use of health-related quality of life tools in hepatobiliary surgery显示文摘BACKGROUND:The objective of this article is to review the literature and discuss the various tools used in hepatobiliary surgery for the measurement of health related quality of life (HR-QOL) and highlight various outcome variables that affect the HR-QOL among patients with common hepatobiliary disorders. DATA SOURCES: We reviewed HR-QOL articles published in the last 20 years on different hepatobiliary curative or palliative procedures in all languages. RESULTS: HR-QOL is a questionnaire tool which is utilized to assess the changes in the health status of patients after a hepatobiliary intervention. These surveys are of increasingly importance, as health care providers are challenged to justify treatment approaches and rationale for any surgical intervention. These HR-QOL tools are very helpful for the evaluation of subjective outcome of common hepatobiliary procedures like gastrointestinal quality of life index (GIQLI) for cholecystectomy, functional assessment in cancer therapy (FACT) for liver resection, short form 36 (SF-36) for liver transplantation, and quality of life questionnaire for patients with pancreatic cancer (QLQ-PAN). CONCLUSIONS: Use of validated and reliable health instruments in hepatobiliary surgery is directed at measuring the impact in a reproducible and valid fashion. Curative or palliative procedures should be offered to the patients of hepatobiliary disorders after the assessment by HR-QOL tools. Because the impairments of function that may occur after different operations vary considerably, an operation-specific assessment of HR-QOL for each type of surgical procedure is becoming an essential principle to follow in a successful healthcare system.Muhammad Shafique Sajid Mawara Iftikhar Jasmin Rimple Mirza Khurrum Baig 2008Hepatobiliary & Pancreatic Diseases International2008,7,2:5

14Robotic total meso-rectal excision for rectal cancer: A systematic review following the publication of the ROLARR trial显示文摘AIM To compare outcomes in patients undergoing rectal resection by robotic total meso-rectal excision(RTME) vs laparoscopic total meso-rectal excision(LTME).METHODS Standard medical electronic databases such as Pub-Med, MEDLINE, EMBASE and Scopus were searched to find relevant articles. The data retrieved from all types of included published comparative trials in pati-ents undergoing RTME vs LTME was analysed using the principles of meta-analysis. The operative, post-operative and oncological outcomes were evaluated to assess the effectiveness of both techniques of TME. The summated outcome of continuous variables was expressed as standardized mean difference(SMD) and dichotomous data was presented in odds ratio(OR).RESULTS One RCT(ROLARR trial) and 27 other comparative studies reporting the non-oncological and oncological outcomes following RTME vs LTME were included in this review. In the random effects model analysis using the statistical software Review Manager 5.3, the RTME was associated with longer operation time(SMD, 0.46; 95%CI: 0.25, 0.67; z = 4.33; P = 0.0001), early passage of first flatus(P = 0.002), lower risk of conversion(P = 0.00001) and shorter hospitalization(P = 0.01). The statistical equivalence was seen between RTME and LTME for non-oncological variables like blo-od loss, morbidity, mortality and re-operation risk. The oncological variables such as recurrence(P = 0.96), number of harvested nodes(P = 0.49) and positive circumferential resection margin risk(P = 0.53) were also comparable in both groups. The length of distal resection margins was similar in both groups. CONCLUSION RTME is feasible and oncologically safe but failed to demonstrate any superiority over LTME for many sur-gical outcomes except early passage of flatus, lower risk of conversion and shorter hospitalization.Katie Jones Mohamed G Qassem Parv Sains Mirza K Baig Muhammad S Sajid 2018World Journal of Gastrointestinal Oncology2018,10,11:4
15Analysis of the effect of passive measures on the energy consumption and zero-energy prospects of residential buildings in Pakistan显示文摘Climate change can adversely impact the thermal comfort and energy efficiency of the buildings stock. The South Asian countries are particularly vulnerable to the adverse impacts of climate change specially in the form of rising temperatures and increasing frequency of heat waves. The passive building design measures can be useful in mitigating and adapting to the climate change by increasing energy efficiency and reducing greenhouse gas (GHG) emissions. In this study various passive climate change adaptation measures (PCAMs) have been used individually and in form of combinations in order to analyze their impact on the energy efficacy of residential buildings in Pakistan. It has been found that the natural ventilation and front green wall are the most efficient options for reducing the overall energy consumption. By implementation of these PCAMs, cooling demand can be decreased by 27.75% while heating demand can be reduced by 35%. Secondly, the prospect of net zero-energy building and reduced CO2 emissions are also studied. It has been shown that building can achieve net-zero energy on an annual basis at every orientation and it can attain the status of nearly zero-energy building on a monthly basis. Moreover, emitted CO2 can be reduced by 31% by using the renewable energy.Muhammad Wasim Anwar Zaib Ali Abdullah Javed Emad Ud Din Muhammad Sajid 2021Building Simulation2021,14,4:3
16Shellfish allergy and relation to iodinated contrast media: United Kingdom survey显示文摘AIM: To assess current practice of United Kingdom cardiologists with respect to patients with reported shellfish/iodine allergy, and in particular the use of iodinated contrast for elective coronary angiography.Moreover we have reviewed the current evidence-base and guidelines available in this area.METHODS: A questionnaire survey was send to 500senior United Kingdom cardiologists(almost 50% cardiologists registered with British Cardiovascular Society)using email and first 100 responses used to analyze practise. We involved cardiologists performing coronary angiograms routinely both at secondary and tertiary centres. Three specific questions relating to allergy were asked:(1) History of shellfish/iodine allergy in pre-angiography assessment;(2) Treatments offeredfor shellfish/iodine allergy individuals; and(3) Any specific treatment protocol for shellfish/iodine allergy cases. We aimed to establish routine practice in United Kingdom for patients undergoing elective coronary angiography. We also performed comprehensive PubMed search for the available evidence of relationship between shellfish/iodine allergy and contrast media.RESULTS: A total of 100 responses were received, representing 20% of all United Kingdom cardiologists. Ninety-three replies were received from consultant cardiologists, 4 from non-consultant grades and 3 from cardiology specialist nurses. Amongst the respondents, 66% routinely asked about a previous history of shellfish/iodine allergy. Fifty-six percent would pre-treat these patients with steroids and anti-histamines. The other 44% do nothing, or do nonspecific testing based on their personal experience as following:(1) Skin test with 1 mL of subcutaneous contrast before intravenous contrast;(2) Test dose 2 mL contrast before coronary injection;(3) Close observation for shellfish allergy patients; and(4) Minimal evidence that the steroid and anti-histamine regime is effective but it makes us feel better.CONCLUSION: There is no evidence that allergy to shellfish alters the risk of reaction to intravenous contrast more than any other allergy and asking about such allergies in pre-angiogram assessment will not provide any additional information except propagating the myth.Mudassar Baig Ahmad Farag Jamal Sajid Rahul Potluri R Bruce Irwin Hafiz Mohammed Idrees Khalid 2014World Journal of Cardiology2014,6,3:3

18Stevenleaf from Gynostemma Pentaphyllum inhibits human hepatoma cell(HepG2)through cell cycle arrest and apoptotic induction显示文摘The anticancer activity of stevenleaf(SV)on the basis of cell viability,cell cycle,and apoptosis induction in HepG2 cancer cells were evaluated.SV controlled the growth of HepG2 cells with IC50 of 139.82μmol/L for 24 h,IC50 of 119.12μmol/L for 48 h and cell cycle arrested at G0/G1 phase,induced cell apoptosis and enhanced intracellular ROS generation.For cell cycle arrest,the mRNA expression levels of p21,p27 and p53 were up-regulated,while the expression levels of Cyclin A,Cyclin D1,Cyclin E and CDK1/2 were downregulated.SV efficiently up-regulated TNF R1,TRADD1 and FADD and down-regulated Caspase8 for cell death receptors;similarly,up-regulated Bax,Bak,Cytc,Apaf1,Caspase3 and Caspase9,and down-regulated Bcl2,Bcl xl and Bad for mitochondrial signal pathway.SV induced the mTOR-mediated cell apoptosis in HepG2 cells via activation of Akt and AMPK.The mechanistic explanation for the anticancer activity of SV as functional food can be derived from above results.Sayed Sajid Hussain Fan Zhang Yuanyuan Zhang Kiran Thakur Mahrukh Naudhani Carlos L.Cespedes-Acuna Zhaojun Wei 2020Food Science and Human Wellness2020,9,3:3
19A New Paradigm for Waste Classification Based on YOLOv5显示文摘Classification of garbage is of paramount importance prior to process them to categorise physically and this process helps to manage wastes by maintaining pollution free environment.Many systems that have capability segregate garbage are on the rise,but efficient and accurate segmentation with recognition mechanisms draw the attention of researchers.A computer vision approach for classifying garbage into respective recyclable categories could be one of the effective and economical ways of processing waste.This project mainly focused on capturing real-time images of a single piece of garbage and classifying it into three divisions:paper,or metal,or biodegradable(food)waste.Each garbage class contains around 2000 images obtained from an open-source dataset and images collected from Google and personally collected custom images.The developed intelligent models provide the effectiveness of the machine and deep learning in classification with structural and non-structural data.The model used was a Convolutional Neural Network(CNN)named YOLOv5.The project showcased vision based approach capable of maintaining an accuracy of 61%.The CNN was not trained to its maximum capacity due to the difficulty of finding optimal hyperparameters,as most of the images were gathered from Google Images.Mohammed SAJID Nimali T MEDAGEDARA 2021Instrumentation2021,8,4:3
20Spatial Pattern and Influencing Factor Analysis of Attended Collection and Delivery Points in Changsha City, China显示文摘Attended collection and delivery points are vital components of ‘last-mile logistics’.Based on point of interest(POI) data for Cainiao Stations and China Post stations in Changsha City, China, this paper provides a detailed exploration of the basic features, spatial distribution, and location influencing factors of attended collection and delivery points.Specifically, analyses of the types, service objects and location distributions of the attended collection and delivery points alongside a discussion of their spatial pattern and influencing factors provides a reference for their general geographic layout and characteristics.The findings of this study indicate that: 1) The main mode of operation of attended collection and delivery points is franchises, with other modes of operation rely on supermarkets and other individual shop types.2) The main service targets of attended collection and delivery points are communities, schools, and businesses, followed by townships, enterprises, scenic spots, and administrative units.3) Approximately 77.44% of the attended collection and delivery points are located near the exits of service areas;others are situated in the centre of the service areas.For the Cainiao Stations, 80% are located within 125 m of the exit;for the China Post stations, 80% are located within 175 m of the exit.4) The spatial distribution of the attended collection and delivery points in Changsha is unbalanced, with ‘more centre and fewer surrounding’.The centre is an ‘inverted triangle’, and the edge is an ‘orphan’, showing a northwest-southeast orientation and symmetrical along the axis.The layout of the attended collection and delivery points forms three core areas, and the number of sites decreases with the distance from the core.5) The number and distribution of the attended collection and delivery points are strongly consistent with the regional economic development level, population, and roadway system traffic convenience.Most attended collection and delivery points are on residential, scientific and educational, and commercial and financial land.XUE Shuyan LI Gang YANG Lan LIU Ling NIE Qifan Muhammad Sajid MEHMOOD 2019Chinese Geographical Science2019,29,6:3
