Experimental mole fraction solubility of lamotrigine(LTG)in ternary aqueous mixtures of two ionic liquids(ILs),1-hexyl and 1-octyl-3-methylimidazolium bromide,[HMIm][Br]and[OMIm][Br]were reported at several temperatures T=(293.15 to 313.15)K.The van’t Hoff and(jouyban-Acree-van’t Hoff,E-jouyban-Acree-van’t Hoff,e-NRTL,UNIQUAC and Wilson)models were used to correlate the solubility data.The comparison of the models with temperature and solvent composition dependencies shows that the Wilson model has the minimum ARD which are relatively close to those obtained from jouyban-Acree-van’t Hoff and E-jouyban-Acree-van’t Hoff models and maximum ARD belonged to the UNIQUAC model.The order of ARDs for these models is:Wilson b jouyban-Acree-van’t Hoff,E-jouyban-Acree-van’t Hoff b e-NRTL b UNIQUAC.Moreover,the apparent thermodynamic functions,Gibbs free energy,enthalpy and entropy of dissolution and mixing were calculated based on the van’t Hoff and Gibbs free energy equations.The strong LTG-ILs interactions and enthalpic contribution of the dissolution process resulted from the calculated thermodynamic functions.

Low toxic graphene quantum dot（GQD） was synthesized by pyrolyzing citric acid in alkaline solution and characterized by ultraviolet-visible（UV-vis） spectroscopy,X-ray diffraction（XRD）,atomic force microscopy（AFM）,spectrofluorimetery and dynamic light scattering（DLS） techniques.GQD was used for electrode modification and electro-oxidation of doxorubicin（DOX） at low potential.A substantial decrease in the overvoltage（- 0.56 V） of the DOX oxidation reaction（compared to ordinary electrodes） was observed using GQD as coating of glassy carbon electrode（GCE）.Differential pulse voltammetry was used to evaluate the analytical performance of DOX in the presence of phosphate buffer solution（pH 4.0） and good limit of detection was obtained by the proposed sensor.Such ability of GQD to promote the DOX electron-transfer reaction suggests great promise for its application as an electrochemical sensor.

AIM:To determine the prevalence of some retinal pathologies in people over 60y and their association with demographic and ocular factors.METHODS:A cross-sectional study was conducted in Tehran using multistage cluster sampling.After selecting subjects aged 60 and over,optometric,and ophthalmic examinations were done.For retinal examination,a 90 D lens was used and indirect ophthalmoscopy was performed after instilling tropicamide drops.Biometry was done using the IOL Master for all participants.RESULTS:Of 3791 people that were invited through cluster sampling,3310 participated in the study(response rate=82%).The prevalence of retinal pigmented epithelium(RPE)change,drusen,geographic atrophy(GA),hypertensive retinopathy(HTR),nonproliferative diabetic retinopathy(NPDR),proliferative diabetic retinopathy(PDR),choroidal neovascularization(CNV),central retinal artery occlusion(CRAO),myopic retinopathy(MR),branch retinal vein occlusion(BRVO),and central retinal vein occlusion(CRVO)was 27.42%,11.08%,4.52%,3.03%,4.05%,0.54%,0.82%,0.39%,0.20%,0.49%,and 0.19%,respectively.After removing the effect of age,the odds of NPDR were 1.68 times higher in women compared to men(P=0.014).After removing the effect of sex,the odds of drusen,RPE change,GA,CNV,BRVO,and CRVO increased with age.CONCLUSION:There is a higher prevalence of RPE change,drusen,GA,CNV and a lower prevalence of MR and CRAO in the elderly population of Tehran aged over 60y compared to global average values.Considering the correlation of most of the diseases with age and their effects on vision,attention should be paid to these diseases and the related screening programs to prevent vision impairment.

AIM:To compare the subjective refraction data with non-cycloplegic auto-refraction findings in the geriatric population above 60 years of age according to the different crystalline lens conditions.METHODS:This report is a part of the Tehran Geriatric Eye Study(TGES)that was conducted from January 2019 to January 2020 on elderly population 60 years of age and above in Tehran.The samples were selected by multistage stratified random cluster sampling.Of 3791 individual invitees,3310(response rate:87.3%)participated in this study.All study participants underwent non-cycloplegic autorefraction(auto-refractometer/keratometer Nidek ARK-510)and subjective refraction.RESULTS:Regarding the sphere,eyes with mixed cataract had the worst limits of agreement(LoA:-1.24 to 0.87)and the best agreement was related to the pseudophakic eyes(LoA:-0.83 to 0.54).The highest(0.27±0.31 D)and lowest(0.21±0.27 D)differences between the two methods regarding the cylinder power were observed in eyes with cortical cataract and normal eyes,respectively.The worst LoA between the two methods in measuring the cylinder power was related to the eyes with mixed cataract(LoA:-0.44 to 0.96).Regarding the J0(horizontal/vertical components of astigmatism),the mean values of J0 obtained by auto-refraction were tended more toward against the rule direction in all crystalline lens conditions,and the two methods had the greatest difference in cortical cataract cases(0.05±0.17 D).Regarding the J45(oblique components of astigmatism),the lowest(0±0.11 D)and highest(-0.01±0.12 D)differences were observed in normal eyes and eyes with cortical cataract,respectively.CONCLUSION:The auto-refractometer/keratometer Nidek ARK-510 results in the elderly with different phakic and pseudophakic conditions do not correspond well with subjective refraction findings.This discrepancy in spherical findings is more pronounced in individuals with mixed cataract than in other cases.

AIM:To determine the prevalence of red-green(RG)color vision deficiency(CVD)in an elderly population and its related factors.METHODS:This report is a part of the Tehran Geriatric Eye Study:a cross-sectional population-based study that was conducted on the elderly population(≥60y)of Tehran,Iran using multi-stage stratified random cluster sampling.All study participants underwent complete ocular examination,including the measurement of uncorrected and bestcorrected visual acuity,objective and subjective refraction,and slit-lamp biomicroscopy.The color vision was tested using Ishihara plates with the near optical correction in place.RESULTS:Of the 3791 invitees,3310 participated in the study.The data of 2164 individuals were analyzed after applying the exclusion criteria.The prevalence of R-G CVD was 3.73%(95%CI:2.37%–5.09%)in the whole sample;the prevalence of protanomaly,protanopia,and deuteranopia was 1.51%,1.76%,and 0.45%,respectively.The prevalence of R-G CVD was significantly higher in males than in females.The prevalence of RG CVD increased with advancing age from 2.91%in the age group 60–64y to 5.8%in the age group≥80y(P=0.070).According to the multiple logistic regression model,male sex,and glaucoma were significantly related to RG CVD.Older age and hypertension also had a marginally significant relationship with RG CVD.CONCLUSION:Changes in color vision occur in the elderly due to the aging process and some physiological and pathological factors.Since the change in visual perception may affect the person’s performance,this aspect of the visual system’s function should also be taken into consideration in the examinations of the elderly.

An anaerobic baffled reactor is a system developed in recent decades and has been used as part of the treatment of high-strength wastewater. Since the function of this system is based on its hydrodynamic features, hydrodynamics and the regime of the flow through the reactor are crucial. In this study, a prototype reactor with eight chambers, which had a total volume of 48 L, and a model reactor, whose dimensions were half of those of the prototype reactor, were used. The Froude dynamic similitude in these reactors was investigated. The results show that the curve dimensionless variances were 0.089 and 0.096 for the prototype and model reactors, respectively, the short-circuiting indices were 0.483 and 0.489 for the prototype and model reactors, respectively, the effective volume and short-circuiting index measurement errors were both 1%, the hydraulic efficiency error was 2%, and the Peclet and dispersion number errors were both 7%. Most of the compared indices were close to one another in value. Therefore, the model reactor can be used based on the Froude dynamic similitude to determine hydrodynamic charac-teristics of a baffled reactor at a full scale.
