| 1 | Comparison of perceived pain and patients’ satisfaction with traditional local anesthesia and single tooth anesthesia: A randomized clinical trial显示文摘BACKGROUND Contemporary innovations in the area of local anesthesia have attempted to provide an absolutely pain free experience for patients.Since the introduction of Computer-Controlled Local Anesthetic Delivery Systems to dentistry,many studies have compared its efficacy and safety to conventional anesthesia.However,very few studies have compared single tooth anesthesia(STA)and traditional local anesthesia.AIM To compare pain rating,changes in blood pressure,and heart rate during the local anesthetic injection.The secondary objectives were to measure the patients’level of satisfaction and the differences in anesthetic efficiency between the STA system and traditional local infiltration.METHODS A randomized controlled trial was conducted and a total of 80 patients with dental restorative needs were enrolled for the study.The patients were evaluated for their general physical status and oral clinical findings before enrollment.Information regarding perceived pain,changes in heart rate and blood pressure,and patients’satisfaction was collected using an electronic data form and was analyzed using paired and unpaired t-tests.RESULTS No significant difference was noted in perceived pain(P=0.59)and systolic blood pressure(P=0.09)during anesthetic injection using both traditional and STA techniques.STA patients had a significantly higher heart rate during anesthesia,although a statistically significant difference was noted among the traditional anesthesia and the STA groups even before anesthesia.During the restorative procedure,less pain was perceived by STA patients on the Wong-Baker FACES pain scale,which was statistically significant(P<0.001).Analyses of post-procedure patient responses showed that STA patients had a significantly better treatment experience and preferred to have the same method of injection in the future(P=0.04).CONCLUSION STA system can provide less painful and more comfortable restorative treatment procedures in comparison to the traditional infiltration technique. | Mohammad I Al-Obaida Mehdiya Haider Rawan Hashim Wafa AlGheriri Sree Lalita Celur Samar A Al-Saleh Ebtissam M Al-Madi | 2019 | World Journal of Clinical Cases2019，7，19： | 8 |
| 2 | Flexible SERS substrates for hazardous materials detection: recent advances显示文摘This article reviews the most recent advances in the development of flexible substrates used as surface-enhanced Ra-man scattering(SERS)platforms for detecting several hazardous materials(e.g.,explosives,pesticides,drugs,and dyes).Different flexible platforms such as papers/filter papers,fabrics,polymer nanofibers,and cellulose fibers have been investigated over the last few years and their SERS efficacies have been evaluated.We start with an introduction of the importance of hazardous materials trace detection followed by a summary of different SERS methodologies with par-ticular attention on flexible substrates and their advantages over the nanostructures and nanoparticle-based solid/hybrid substrates.The potential of flexible SERS substrates,in conjunction with a simple portable Raman spectrometer,is the power to enable practical/on-field/point of interest applications primarily because of their low-cost and easy sampling. | Moram Sree Satya Bharati Venugopal Rao Soma | 2021 | Opto-Electronic Advances2021，4，11： | 6 |
| 3 | Alkali salts of heteropoly tungstates: Efficient catalysts for the synthesis of biodiesel from edible and non-edible oils显示文摘Alkali salts of tungsten based heteropoly acids with different central atom such as P, Si and Co were prepared and evaluated for transesterification of both edible and non-edible oils to their corresponding fatty acid methyl esters. The catalyst of sodium salt of tungstic acid with Co as central atom(Na5Co W12O40) showed optimum activity towards transesterification compared with other heteropoly tungstates.The catalysts activities were correlated with the observed physico-chemical characteristics derived from FT-infrared(FT-IR), X-ray diffraction(XRD), temperature-programmed desorption of ammonia(NH3-TPD) and carbon dioxide(CO2-TPD). The Na5 Co W12O40catalyst exhibiting high activity even at 65°C is due to the presence of strong acidic as well as basic sites. The disclosed catalyst is tolerable towards water and free fatty acids present in the oils. The influence of catalyst loading, reaction time and reaction temperature is studied to optimize the reaction parameters. | Rekha Sree Sunny Kuriakose | 2015 | Journal of Energy Chemistry2015，24，1： | 4 |
| 4 | Joining of AZ31 and AZ91 Mg alloys by friction stir welding显示文摘Two dissimilar magnesium(Mg)alloy sheets,one with low aluminium(AZ31)and another with high aluminium(AZ91)content,were successfully joined by friction stir welding(FSW).The effect of process parameters on the formation of hot cracks was investigated.A sound metallurgical joint was obtained at optimized process parameters(1400 rpm with 25 mm/min feed)which contained fine grains and distributed β(Mg_(17)Al_(12))phase within the nugget zone.An increasing trend in the hardness measurements has also confirmed more amount of dissolution of aluminium within the nugget zone.A sharp interface between nugget zone and thermo mechanical affected zone(TMAZ)was clearly noticed at the AZ31 Mg alloy side(advancing)but not on the AZ91 Mg alloy side(retreating).From the results it can be concluded that FSW can be effectively used to join dissimilar metals,particularly difficult to process metals such as Mg alloys,and hot cracking can be completely eliminated by choosing appropriate process parameters to achieve sound joint. | B.Ratna Sunil G.Pradeep Kumar Reddy A.S.N.Mounika P.Navya Sree P.Rama Pinneswari I.Ambica R.Ajay Babu P.Amarnadh | 2015 | Journal of Magnesium and Alloys2015，3，4： | 3 |
