| 2 | Relationship of knowledge about osteoporosis with education level and life habits显示文摘AIM: To assess possible relationships of knowledge and related factors with educational level and osteoporosisrelated life habits.METHODS: This was a cross sectional study conducted on 268 women(≥ 35 years old) from June 2011 to August 2011. The sample collection was done in outpatient clinics in three university hospitals in Isfahan, Iran. We used a demographic questionnaire containingquestions that evaluated osteoporosis-related life habits, including exercise, smoking, intake of calcium and vitamin D supplements and so on. We also used the Osteoporosis Knowledge Assessment Tool to measure osteoporosis knowledge of women.RESULTS: The mean level of knowledge about awareness of osteoporosis, its risk factors and preventive factors were 56, 55 and 22, respectively. The relationship of education level and awareness of osteoporosis, its risk factors and preventive factors was significant, with R = 0.76, R = 0.73 and R = 0.83, respectively(P < 0.001). The relationship of education level and osteoporosis-related life habits was not significant(R = 0.03 and P = 0.56). The relationship of osteoporosis-related life habits and awareness of osteoporosis and its risk factors was significant, with R = 16%, P = 0.006 and R = 16%, P = 0.008, respectively, but the relationship of osteoporosis-related life habits and preventive factors was not significant(R = 0, P = 0.99).CONCLUSION: Iranian women with a higher education level have significantly better knowledge about osteoporosis than women with a lower educational level but they do not use this knowledge in their life. | Mohammad Reza Etemadifar Sayed-Mohammadamin Nourian Mahboobe Fereidan-Esfahani Hamidreza Shemshaki Mohsen Nourbakhsh Abolghasem Zarezadeh | 2013 | World Journal of Orthopedics2013，4，3： | 4 |
| 3 | Cobalt Sulfide Confined in N-Doped Porous Branched Carbon Nanotubes for Lithium-Ion Batteries显示文摘Lithium-ion batteries(LIBs) are considered new generation of large-scale energy-storage devices.However,LIBs suffer from a lack of desirable anode materials with excellent specific capacity and cycling stability.In this work,we design a novel hierarchical structure constructed by encapsulating cobalt sulfide nanowires within nitrogen-doped porous branched carbon nanotubes(NBNTs)for LIBs.The unique hierarchical Co9S8@NBNT electrode displayed a reversible specific capacity of 1310 mAhg-1 at a current density of 0.1 Ag-1,and was able to maintain a stable reversible discharge capacity of 1109 mAhg-1 at a current density of 0.5 Ag-1 with coulombic efficiency reaching almost 100% for 200 cycles.The excellent rate and cycling capabilities can be ascribed to the hierarchical porosity of the one-dimensional Co9S8@NBNT internetworks,the incorporation of nitrogen doping,and the carbon nanotube confinement of the active cobalt sulfide nanowires offering a proximate electron pathway for the isolated nanoparticles and shielding of the cobalt sulfide nanowires from pulverization over long cycling periods. | Yongsheng Zhou Yingchun Zhu Bingshe Xu Xueji Zhang Khalid A.Al.Ghanim Shahid Mahboob | 2019 | Nano-Micro Letters2019，11，2： | 3 |

| 6 | Anti-encystment and amoebicidal activity of Lonicera japonica Thunb. and its major constituent Chlorogenic acid in vitro显示文摘Objective:To examine the acanthamoebicidal effects of ethyl acetate,aqueous and butanol fractions of dried flower buds of Lonicera japonica(L.japonica) Thunb.(Flos Lonicerae) in vitro.Methods:Acanthamoeba triangularis isolates were obtained from environmental water samples and identified by PCR.They were exposed to ethyl acetate,water and butanol fractions of L.japonica Thunb.at concentrations ranging from 0.5 mg/m L to 1.5 mg/m L.The extracts were evaluated for growth inhibition at 24,48 and 72 h,respectively.Chlorogenic acid at a concentration of 1 mg/mL was examined for inhibition of encystment.Results:Ethyl acetate fraction at a concentration of 1.5 mg/mL evoked a significant reduction of trophozoite viability by 48.9% after 24 h,49.2% after 48 h and 33.7% after 72 h Chlorogenic acid,the major active constituent of L.japonica Thunb.at the concentration of 1 mg/mL reduced the cysts/trophozoite ratio by 100% after 24 h,84.0% after 48 h and 72.3% after 72 h.This phenolic compound at concentration of 1 mg/mL concurrent with 0.6% hydrogen peroxide inhibited hydrogen peroxide-induced encystment by 92.8% at 72 h.Conclusions:Results obtained from this study show that ethyl acetate fraction at 1.5 mg/m L is the most potent fraction of L.japonica Thunb.and its major constituent chlorogenic acid showed the remarkable inhibition of encystment at a concentration of 1 mg/mL. | Tooba Mahboob Abdul-Majid Azlan Tian-Chye Tan Chandramathi Samudi Shamala Devi Sekaran Veeranoot Nissapatorn Christophe Wiart | 2016 | Asian Pacific Journal of Tropical Medicine2016，9，9： | 2 |
| 7 | Recent 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 | 2022 | Rice science2022，29，2： | 2 |

| 19 | An Innovative Technique for Constructing Highly Non-Linear Components of Block Cipher for Data Security against Cyber Attacks显示文摘The rapid advancement of data in web-based communication has created one of the biggest issues concerning the security of data carried over the internet from unauthorized access.To improve data security,modern cryptosystems use substitution-boxes.Nowadays,data privacy has become a key concern for consumers who transfer sensitive data from one place to another.To address these problems,many companies rely on cryptographic techniques to secure data from illegal activities and assaults.Among these cryptographic approaches,AES is a well-known algorithm that transforms plain text into cipher text by employing substitution box(S-box).The S-box disguises the relationship between cipher text and the key to guard against cipher attacks.The security of a cipher using an S-box depends on the cryptographic strength of the respective S-box.Therefore,various researchers have employed different techniques to construct high order non-linear S-box.This paper provides a novel approach for evolving S-boxes using coset graphs for the action of the alternating group A5 over the finite field and the symmetric group S256.The motivation for this work is to study the symmetric group and coset graphs.The authors have performed various analyses against conventional security criteria such as nonlinearity,differential uniformity,linear probability,the bit independence criterion,and the strict avalanche criterion to determine its high cryptographic strength.To evaluate its image application performance,the proposed S-box is also used to encrypt digital images.The performance and comparison analyses show that the suggested S-box can secure data against cyber-attacks. | Abid Mahboob Muhammad Asif Rana Muhammad Zulqarnain Imran Siddique Hijaz Ahmad Sameh Askar Giovanni Pau | 2023 | Computer Systems Science & Engineering2023，47，11： | 1 |
| 20 | Effect of pollution on DNA damage and essential fatty acid profile in Cirrhinus mrigala from River Chenab显示文摘The objective of this study was to evaluate the effect of anthropogenic pollution on DNA damage and the fatty acid profile of the bottom dweller fish( Cirrhinus mrigala), collected from the River Chenab, in order to assess the effect of the toxicants on the quality of the fish meat. The levels of Cd, Hg, Cu, Mn, Zn, Pb, Cr and Sn and of phenols from this river were significantly higher than the permissible limits set by the USEPA. Comet assays showed DNA damage in Cirrhinus mrigala collected from three different sampling sites in the polluted area of the river. Significant differences were observed for DNA damage through comet assay in fish collected from polluted compared to control sites. No significant differences were observed for DNA damage between farmed and fish collected from upstream. The micronucleus assay showed similar trends. Fish from the highly polluted sites showed less number of fatty acids and more saturated fatty acids in their meat compared to fish from less polluted areas. Several fatty acids were missing in fish with higher levels of DNA in comet tail and micronucleus induction. Long-chain polyunsaturated fatty acids, eicosapentaenoic acid(20:5n-3) was found missing in the fish from polluted environment while it was found in considerable amount in farmed fish 7.8±0.4%. Docosahexaenoic acid(22:6n-3) also showed significant differences as 0.1±0.0 and 7.0±0.1% respectively, in wild polluted and farmed fishes. | Bilal HUSSAIN Tayyaba SULTANA Salma SULTANA K.A.AL-GHANIM Shahid MAHBOOB | 2017 | Chinese Journal of Oceanology and Limnology2017，35，3： | 1 |
