Published: October 2022

Abstract. Bedrock permafrost is a feature of cold mountain ranges that was found responsible for the increase of rock fall and landslide activity in several regions across the globe. In Greenland, bedrock permafrost has received so far little attention from the scientific community, despite mountains are a predominant feature on the ice-free coastline and landslide activity is significant. With this study, we aim to move a first step towards the characterization of bedrock permafrost in Greenland. Our study area covers 100 km2 of mountain terrain around the town of Sisimiut – 68° N on the West Coast. We first acquire surface ground temperature data from 2020–2021 to model bedrock surface temperatures time series from weather forcing on the period 1850–2022. Using a topographical downscaling method based on digital elevation model, we then create climatic boundary conditions for 1D and 2D heat transfer numerical simulations at the landscape level. In this way we obtain permafrost distribution maps and ad-hoc simulations for complex topographies. Our results are validated by comparison with temperature data from two lowland boreholes (100 m depth) and geophysical data describing freezing/unfreezing conditions across a mid-elevation mountain ridge. Finally, we use regional carbon pathway scenarios 2.6 and 8.5 to evaluate future evolution of ground temperatures to 2100. Our results indicate a sporadic permafrost distribution up to roughly 400 m.a.s.l., while future scenarios suggest a decline of deep frozen bodies up to 800 m.a.s.l., i.e. the highest summits in the area.
I beni degli esuli. I sequestri austriaci nel Lombardo-Veneto (1848-1866)
Authors: Girardi Giacomo
Published: October 2022

Il volume ricostruisce, avvalendosi di un ampio scavo archivistico, uno degli aspetti meno noti dell’esilio risorgimentale: il sequestro dei patrimoni di coloro che furono costretti ad abbandonare il suolo patrio. Nel 1853, quando il feldmaresciallo Radetzky, governatore generale del Regno Lombardo-Veneto, impartì l’ordine di sequestrare i beni degli esuli politici, la macchina amministrativa asburgica si mise lentamente in moto, impossessandosi temporaneamente delle loro fortune. Privati delle consuete rendite, gli uomini e le donne trasferitisi oltreconfine furono profondamente toccati dai provvedimenti di sequestro, che fornirono nuovi argomenti alla leggenda nera del malgoverno austriaco sulle province italiane dell’impero. Queste pagine ripercorrono quelle vicende da una prospettiva economica, sociale e giuridica, indagandole nell’agire dell’amministrazione austriaca, nelle traversie degli emigrati colpiti dai provvedimenti e nelle difficoltà delle loro famiglie rimaste in patria. Ne emerge un quadro vivido, nel quale il legame tra politica e proprietà si esplicita in un intreccio tra controllo pubblico, prassi burocratica e strategie famigliari.
The theory on the natural elements in the philosophical and theological system of the Byzantine thinker George Pachymeres
Authors: Petridou Lydia , Terezis Christos
Published: October 2022

In this paper we discuss the general question on how a Byzantine philosopher-theologian of the late Palaeologan Renaissance forms some aspects of Natural Science. Specifically, focusing on George Pachymeres’ Paraphrasis of Pseudo-Dionysius the Areopagite’s De divinis nominibus, we investigate how this philosopher builds his theory on the natural elements (earth, air, water, fire). We raise a number of questions that have to do with the way in which the elements exist, what is their relation to matter, how causality works in this case and whether priority is given to Ontology or Epistemology. From a methodological point of view, we approach the text scientifically, philosophically and theologically. The most important conclusion that we draw is that in this commentary George Pachymeres’ references on the elements can be placed into three categories (the elements 1. as the products of the divine energies; 2. as cosmological sources; 3. as allegorical names), depending on the context. Finally, we can contend that, although he does not present here a systematic theory on the elements, the Byzantine thinker, who has a thorough knowledge of both the Platonic and Aristotelian tradition, manages to conceive the concept of the “element”.
La tolerancia en Søren Kierkegaard
Authors: Tapia Wende Matías Andrés
Published: October 2022

El contacto del filósofo danés Søren Kierkegaard con el concepto de tolerancia está condicionado por el uso propiamente moderno del término. Esta noción encontró su camino hacia Dinamarca a través de N. F. S. Grundtvig, una de las principales figuras del contexto intelectual de Kierkegaard. Kierkegaard se aleja de la tolerancia de corte indiferente que defiende Grundtvig, pero también rechaza una intolerancia violenta y coercitiva. En este marco, el objetivo de este artículo es bosquejar el lugar que ocupa la tolerancia en el pensamiento cristiano de Kierkegaard y la contribución que puede significar para repensar las relaciones intersubjetivas y sociales.
Mind management 2.0: The internet and the myth of individualism and personal choice in neoliberal times
Authors: Pedro-Carañana Joan , Armirola-Garcés Ledy
Published: October 2022

The year 2023 marks the 50th anniversary of the publication of Herbert I. Schiller’s The Mind Managers that carried out a critical political economy analysis of the myths that sustained industrial capitalism and the role played by the media and cultural industries in their dissemination. As a tribute, this paper highlights the value of Schiller’s work, tracing the historical origins of, and updating, what he considered to be the most important myth in this groundbreaking book: individualism and personal choice. The research shows that this myth has strengthened and undergone important changes in the technologically-centered neoliberal context of today’s cognitive capitalism, where its function is to hide and idealize the present-day structural conditions. The prevalence and characteristics of this myth are analyzed through the paradigmatic example of dating apps. Both the possibilities and limitations provided by media technologies are considered in the context of power relations.

Authors: Bhandari Umesh
Published: October 2022

Vehicle Routing Problem (VRP) is a well-known challenging nondeterministic polynomial-time hard (NP-hard) problem in logistics domain. Time window based VRP is an extension of the problem. The basic problem is to identify optimal set of routes for a fleet of vehicles to traverse to deliver to a given set of customers in a specified time duration. The objective is to minimize the costs of traversed routes. This paper proposes a machine learning and TSP based cluster redistribution approach to solve the time window based VRP. The proposed approach consists of three phases: machine learning based cluster creation, TSP based cluster routes and cluster re-distribution. The results demonstrate the efficacy and optimality of the proposed solution.

Diabetes mellitus is notoriously known around the globe for its pathological problems and it is mostly linked with metabolic, cellular, and blood disorders. In previous studies, the biochemical and hematological anomalies have been associated with type 2 diabetes disorder. In studying this, we compared and analyzed the hematological and biochemical parameters between non-diabetic and diabetic patients from Quetta, Pakistan, and highlighted the anomalies. The results of this study discovered significant anomalies in the biochemical and hematological parameters of diabetic type 2 patients compared with non-diabetic patients. In this study, we conducted a comparative cross-sectional analysis on 100 volunteers among them 50 volunteers were diabetic type 2 patients and the remaining 50 were taken as control these volunteers were selected by applying a systematic random sampling technique. For hematological andbiochemical analysis 5ml of blood from the patients and control group was drawn and subsequently analyzed using an automated cell counter. That was analyzed by using SPSS 22 version. In this study, the majority of subjects in both groups were females. The results of this study displayed that the level of MCV, PVC, RBCs, and hemoglobin was significantly lower compared to diabetic-free individuals. Whereas; mean WBCs and MCHC were highly significant in diabetics patients than the diabetic-free individuals. We did not observe any difference in the level of MCH between both groups. In the case of biochemical parameters comparison, the mean of LDL, TC, creatinine, and urea was higher in the diabetic group as compared to the control group and the value of HDL was lower in the diabetic group.

Published: October 2022

Salmonella is one of the most common causes of foodborne diseases among humans worldwide. Animal-derived foods are frequently tested for the presence of Salmonella spp. However, the detection of Salmonella in meat and its products is often hindered due to the presence of background normal flora, which may lead to the detection of false-positive Salmonella. The present study aimed to isolate and accurately identify Salmonella spp. from poultry meat. For this purpose, seventy poultry meat samples were collected from Lahore, Pakistan, isolated on selective and differential media, and identified using biochemical tests and polymerase chain reaction for the 16S rRNA gene of identified strains. The results of selective and differential media culturing and biochemical tests were compared with the results of 16S rRNA gene sequencing. It was inferred that the phenylalanine deaminase test and triple sugar iron tests eliminate the false-positive Salmonella isolates obtained on isolation media, and along with the PCR technique, can serve as an accurate and efficient method for the correct detection of Salmonella spp. from meat samples. In order to reduce the false-positive Salmonella isolates, a highly specific selective media must be designed which can distinguish Salmonella forming different colors of colonies from other bacteria and also cause the inhibition of non-Salmonellaisolates.

Published: October 2022

Background: Osteoarthritis is a degenerative disorder commonly affecting any joints mostly joints of hands, knees, spine and hips. The disorder occurs when wear and tear of the protective layer of cartilage cushioning the ends of the bones occurs. The symptoms start with pain and stiffness the joints slowly leading to stiffness, tenderness, loss of flexibility, grating sensation, swelling and formation of bone spurs. Osteoarthritis causes deterioration of connective tissue and inflammation of the joint lining. Glucosamine sulphate found in the human body is a naturally occurring chemical which is especially present in the fluid around the joints and is involved in building ligaments cartilage and thick fluid that surrounds the joints. Sulphate part is important for building the cartilage. Sulfasalazine is anti-inflammatory drug and is used to treat and reduce inflammation. In this study the combination of glucosamine sulphate and sulfasalazine is used in combination to test the efficacy in reduction of inflammation and pain in comparison with sulfasalazine alone. Materials and Methods: In this prospective randomized controlled study 60 patients of osteoarthritites between the age group of 18 to 60 years were selected. Patients were divided into two groups (A and B). Age, severity of the disease was taken into consideration while grouping the patients. Group A was treated with Sulfasalazine alone 500mg once a day and group B with combination of Glucosamine Sulphate (oral) 750mg twice a day and Sulfasalazine (oral) 500mg once a day. Assessments of number of swollen joints and VAS and faces pain rating (scale) were carried out once in a month. Results: After six months 67% reduction in number of swollen joints and 76% of duration of morning stiffness in combination therapy was observed compared to 54% and 65% of reduction respectively in sulfasalazine alone. VAS score after six months was found to be 1 in combination therapy and 3 in suflasalazine alone. Conclusion: The study concluded that the combination treatment regimen glucosamine sulfate and oral sulfasalazine improved patient mobility, decreased number of swollen joints and decreased arthritic pain gradually.

Published: October 2022

Raloxifene (RLX) and Curcumin (CUR) are used for the treatment of breast cancer. Its combination is chosen because of their synergistic therapeutic potential, which helps to reduce drug-related toxicities while increasing therapeutic efficacy. A simple, sensitive, accurate and specific technique for determining retention time by employing reverse-phase high-performance liquid chromatography for simultaneous estimation of both the drugs was developed as well validated for the analysis on their particular wavelength. The separation was performed on an RP C-18 Column (EC 250/4 neucleosil 100-10) with column dimensions 250mm x 4.60mm, 10mM using mobile phase Potassium dihydrogen phosphate: acetonitrile (pH 3.0 with Orthophosphoric acid) in the ratio of 20:80 v/v and flow rate of 1.0min/mL. The specificity, linearity range, accuracy, sensitivity, robustness, precision, and ruggedness of the method were all determined. The analyte's peaks were found to be well resolved, and two different RTs for RLX and CUR were observed. Over a concentration range of 1-5g/ml, RLX and CUR calibration curves were shown to be linear. All of the technique validation criteria were within acceptable limits. For inter- and intra-day precision, the relative standard deviation (%RSD) was found to be <2%.

Authors: G. Modh Pratik , J. Patel Laxman
Published: October 2022

Diabetes mellitus is a metabolic condition characterised by chronic hyperglycaemia, and type II diabetes is the most common type, accounting for 90% of cases globally. Hyperglycaemia is major complication of Diabetes mellitus. Postprandial hyperglycaemia is the most common distinctive of diabetes. Inhibition of carbohydrate hydrolysing enzymes including amylase and glucosidase may be useful method for lowering postprandial blood sugar levels. Alpha amylase and glucosidase inhibitors are the most approaching targets in the development of lead compounds for the treatment and management of diabetes. This type of inhibitors, used in clinical practise for the treatment of diabetes are known to be associated with gastrointestinal side effects. Therefore, we need to synthesize new compounds which have fewer side effects. In present study synthesized thirty quinazolinone compounds (PM1-PM30) were screened for their inhibitory effect on alpha amylase and alpha glucosidase enzymes. All synthesized compounds PM1 to PM 30, possess good inhibitory activity similar to that of approved drug Acarbose. Compounds PM20 PM7, PM28, PM29 are remarkable potent alpha amylase inhibitors and compounds PM30, PM28, PM29, PM4 are remarkable potent alpha glucosidase inhibitors. Therefore, these compounds are beneficial for management and treatment of diabetes disorder.
Bayesian optimization and design of experiments
Authors: Misener Ruth
Published: October 2022

Bayesian optimization is a popular machine learning-based approach for optimizing black-box functions, with successful applications including hyperparameter tuning of machine learning algorithms, design of engineering systems, and sensor set selection. After introducing Bayesian optimization, we present some joint research with the BASF Data Science for Materials Chemistry teams. With BASF, we’re interested to solve Bayesian optimization challenges which may simultaneously exhibit: multiple objectives, mixed-feature spaces, asynchronous decisions, large batch sizes, input constraints, multi-fidelity observations, hierarchical choices, and costs associated with switching between experimental points. We review the machine learning contributions that we’ve found useful towards achieving these goals and discuss our own methodological and software contributions.

We review work from many groups. My own work is a collaboration between Imperial (Jose Pablo Folch, Alexander Thebelt, Shiqiang Zhang, Jan Kronqvist, Calvin Tsay, Ruth Misener) and BASF (Robert Lee, Behrang Shafei, Nathan Sudermann-Merx, David Walz).

Соматические стволовые клетки представляют собой редкие гетерогенные популяции недифференцированных клеток, которые обнаруживаются в организме на протяжении большей части постнатальной жизни, и их основная роль заключается в поддержании тканевого гомеостаза. С возрастом соматические стволовые клетки стареют, и стареющие клетки накапливаются, способствуя возникновению возрастных заболеваний. Различные популяции соматических стволовых клеток стареют тканеспецифично, и уровень старения стволовых клеток зависит от ряда внутренних и внешних факторов. Точные механизмы, лежащие в основе старения стволовых клеток, до конца не выяснены. В данном обзоре обсуждаются текущее понимание и последние открытия, касающиеся влияния старения на стволовые клетки, примеры сигнальных путей, участвующих в процессе старения, и влияние внешних факторов на старение.

Somatic stem cells are heterogeneous populations of undifferentiated cells found in the body throughout most of postnatal life. Their leading role is to maintain tissue homeostasis. Somatic stem cells age and these aging cells accumulate and contribute to various age-related diseases. Different populations of somatic stem cells age tissue-specifically, and the level of stem cell aging depends on many internal and external factors. The exact mechanisms underlying stem cell aging are not fully understood. This review discusses current understanding and recent discoveries regarding the effect of aging on stem cells, examples of signaling pathways involved in the aging process, and the influence of external factors on aging.

В современных условиях наряду с постоянно растущими темпами потребления мине¬рального сырья требованием времени стало вовлечение вторичного сырья в общую производственную цепочку. Комплексное потребление сырья становится значимым также для решения экологических проблем и задач, связанных с умень¬ше¬нием объёмов хвостохранилищ. Для обоснования и выбора технологических схем и технико-экономических показателей по дальнейшей переработке хвостохранилищ крайне важно определение качественных и количественных показателей хвостов, уста¬новление закономерностей их укладки и распределения на территории хвостохра¬нилища, а также взаимодействие с другими химическими элементами и жидкой массой на хвостохранилище.
В работе приведены примеры и выполнен анализ мирового опыта по решению вышеуказанных вопросов на хвостохранилищах, сооруженных при разработке ряда месторождений меди, никеля, золота и урана.
Приведены результаты исследования хвостов законсервированного хвостохра¬нилища ЗАО “Зангезурский медно-молибденовый комбинат (ММК)”, расположенного в ущелье реки Пухрут. По результатам выполненных химических исследований проб, отобранных из пробуренных на хвостохранилище скважин, установлены закономер¬ности распределения содержания меди и молибдена в хвостах. На основе результатов выполненных исследований разработана трехмерная модель хвостохранилища в ущелье реки Пухрут. На примере условной меди показано распределение металлов в хвостах. Обоснованы также возможные причины образования зон с повышенным содержанием металлов в хвостохранилище.
ПРЕВРАЩЕНИЯ ПРОМЫШЛЕННЫХ ОТХОДОВ АРМЕНИИ В РЕЗУЛЬТАТЕ МЕХАНОХИМИЧЕСКОЙ АКТИВАЦИИ

Published: October 2022

Работа посвящена проблемам извлечения железа и кремния из медно-молиб¬деновых отходов действующих металлургических предприятий Республики Армения с целью получения ферросилиция. Ферросилиций благодаря своим многочисленным ценным свойствам (кислотостойкость, коррозионная стойкость, высокая механическая прочность, магнитно-электрические свойства) получил широкое распространение в современной технике, особенно в производстве легированных сталей. Он также ис¬пользуется на существующих металлургических предприятиях республики в качестве восстановителя, заменяя дорогостоящий и дефицитный кремний.
В работе предлагается комбинированный метод получения ферросилиция путем сочетания метода меха¬ноактивации с методом самораспространяющегося высо¬котемпературного син¬теза, т.е комбинированным алюминотермическим восстанов¬лением оксидов железа и кремния, содержащихся в шлаке. Однако железо-кремний находится в шлаке в виде фаялита (FeO•SiO2, 2FeO•SiO2) и магнетита (Fe3O4), которые являются довольно реакционно-инертными, поскольку они получаются при высоких температурах в процессах металлургии меди и молибдена.
Целью работы является проведение комплексных физико-химических иссле¬дований шлака (минералогия, зернисто-поверхностная морфология элементов) на примере Алавердийского медеплавильного завода, а также молибденового шлака Ереванского завода чистого железа. Для этой цели изучается поведение основных компонентов шлака: фаялита, магнетита и кварцита, в результате тонкого измельче¬ния. Эксперименты показали, что фаялит-магнетит претерпевает различные мелко¬зернистые фазовые превращения после 60 мин тонкого измельчения с образованием в конечном итоге реакционноспособных оксидов кремния и железа. Получающиеся в результате активированные оксиды могут быть использованы в качестве сырья для производства феррокремниевых сплавов, в частности ферросилиция. Подтверждены результаты химического рентгенофазового анализа.

Published: October 2022

Introduction: Hydroxychloroquine (HCQ) is used for treating systemic lupus erythematosus (SLE). It can cause irreversible toxic retinopathy, we discuss the outcome of HCQ retinopathy and emphasize the distinct toxicity pattern in Asian patients.

Case Series: We report a retrospective case series of two systemic lupus erythematosus (SLE) patients who presented with HCQ toxicity. Both Asian SLE patients were treated with HCQ over five years with cumulative dose of >1000 g. Both had characteristic findings on spectral domain optical coherence tomography (SD-OCT) and fundus autofluorescence (FAF). First patient had non-leaking cystoid macula edema (CME) associated with HCQ retinopathy and second patient had bull’s eye maculopathy (BEM). They exhibited different outcome after drug cessation. There was no disease progression in former whereas latter lost her central vision over two years.

Conclusion: Non-leaking CME is rare and can be a sequence of HCQ retinopathy. Bull’s eye maculopathy is another manifestation of severe HCQ toxicity. Toxic damage to retina is irreversible, and may progress even after the drug is stopped, so is crucial to discontinue once toxicity is detected. Patients on HCQ warrant annual screening with multimodal imaging. There are racial differences in HCQ toxicity, hence distinct screening tests should be performed in Asian population.

Paper or cardboard with porous surfaces have been transformed into oil- and water-resistant surfaces by coating them with nano-PET to fill the pores and increase their ability to absorb oil while keeping the fibers from swelling. Experimental results show that using PET nanoparticle solution as coating for cartoon have a strong effect on its mechanical properties especially as confining properties. Cartoon coated show high resistance against water absorption for cartoon with three layers of paint (two sides) where the ratio reach to 41.7% as compare with 16.4% for cartoon without coating also show high confining properties against two kinds of oils (cooking and machine), where the experimental result for the cartoon with two layers of paint lowest absorption  for cooking oil about  0.018 g compared with carton without coating with 0.122g while for machine oil carton with three-layer paint (two side) show the difference in weight about 0.012g and without coating its about 0.026g. Furthermore, high binding energy between the PET nanoparticle solution with the cardboard molecules, which refers that the compatibility between the surface of the treated carton and the PET polymer has occurred, providing a good adhesion between carton and coating solution.

Microbial communities with their key roles in nutrient cycling and degradation of pollutants aresuitable bio-indicators in gauging the health of a marine ecosystem. However, insights into thestructure and diversity of bacterial communities in sediments of Versova creek of Mumbai arelacking. Here we assessed the bacterial diversity and composition in sediments collected from twosampling stations for two months in Versova creek. The total sediment DNA was extracted andsubjected to high throughput 16S rRNA sequencing technology which resulted in a total of 5467unique OTUs (Operational Taxonomic Units) from four samples. 16S rRNA sequences revealed thedominance of phyla Proteobacteria, Bacteriodetes, Tenericutes, Chloroflexi and Firmicutes. Furthertaxonomic analysis revealed the surface sediments to be abundant in sulfate reducing taxaDeltaproteobacteria (Desulfobacteraceae, Desulfobulbaceae and Desulfarculaceae). Organic matterloading and oxygen availability could be one of the prime factors affecting the bacterialcommunity structure in the sediments of Versova creek. Additionally, except for Nickel andCopper, which surpassed the toxic thresholds set by international sediment quality standards, theconcentration of most select heavy metals in the creek sediments revealed a moderate level ofcontamination. This study provides preliminary evidence of pollution in Versova creek due torelease of contaminants beyond the assimilative capacity of the ecosystem. It provides a baselineassessment that can be used as a benchmark for future studies and policies that needs to bedeployed in restoring the health of this system.

Published: October 2022

Traffic and industrial emission generate air pollutants which have been associated with respiratoryhealth symptoms of human beings. Although there is positive association between air pollutionand respiratory health, but the degree of association among different seasons varies due to thecomposition of different air pollutants. Present studies have been carried out to monitor and recordthe particulate and gaseous air pollutants (PM2.5, PM10, NO2 and SO2) in ambient air at IndraChowk, Gajraula (U.P.) during winter and rainy seasons. The level of PM2.5, NO2 and SO2 had beenfound significantly higher during winter as compared to the rainy season. Due to higher level ofair pollutants in ambient air, the incidence of respiratory diseases increased in winter seasons. Thesymptoms of cough, phlegm, headache and eye irritation had been found significantly higher inthe road-side venders during winter months as compared to other seasons of the year. However,their blood oxygen saturation had been recorded significantly higher during the rainy months.

Published: October 2022

Histological alterations are sensitive biomarkers for xenobiotic effects and it is a tool for thediagnosis of direct and indirect toxic effects that affect the animal tissues. Fish gills aremultifunctional organs involved in ion transport, gas exchange, acidâ base regulation and wasteexcretion. Furthermore, the gills are the main route of toxicants penetration into the fish organism,thus they are the first organ, which comes in contact with environmental pollutants and aresensitive subjects for identifying the effects of water toxicants on the fish tissues. Therefore, it isconsidered as an excellent method for assessing environmental quality. Histopathologicalanalysis of gills of Anabas testudineus exposed to sublethal concentrations of monocrotophos wasstudied. Estimation of the maximum allowable toxicant concentration of monocrotophos (MATC) andits application factor (AF) for the Anabas testudineus, was derived based on no observable effectconcentration (NOEC) and the least observable effect concentration (LOEC). MATC and AFcalculated for the pesticide was 13.4164ppm and 0.1308 respectively. The Application Factor, whichis worked out for one species can be used for other related species also, provided their 48hr LC50is known. From this the MATC for latter species can be conveniently found out. This will be animportant tool for the farmers in deciding the concentrations of pesticides before its applicationinto the paddy fields.

Introduction: Maxillary sinus mucosal thickening is a very common disease that is attributed to several reasons including environmental and anatomical. The aim of this study was to investigate the prevalence and relationship between nasal septum deviation and maxillary sinus mucosal thickening using cone-beam computed tomography imaging. Methods: The nasal cavities and maxillary sinuses of 226 patients (169 women and 57 men) were retrospectively examined using cone beam computed tomography. Statistical analysis was done to determine the prevalence and relationship between the nasal septum deviation and maxillary sinus mucosal thickening regarding gender and age. The level of significance was set at 0.05 and statistical analysis was done using the SPSS version 26. Results: The average age of the participants was 43.7 ± 13.3 years. The prevalence of deviated nasal septum was 87.6% (95% CI, 82.6-91.3%), and no significant relationship between nasal septum deviation and age and gender was observed. The highest frequency of nasal septum deviation according to the Meladina classification modified by Rao et al. was assigned to type 7 (36%). Mucosal thickness > 2 mm was found in the right and left maxillary sinuses, 36.7%, and 34.5%, respectively.

Background- Phacoemulsification is considered not only as a cataract surgery but also as a refractive surgery due to negligible astigmatism following micro incision and refractive error correcting/ presbyopia correcting IOLs. Objective- To evaluate the effect of anterior capsule polishing on capsular bag and IOL position after phacoemulsification. Methods- In this prospective randomized clinical trial comprised of 120 eyes of 60 consecutive patients with bilateral age related cataract who undergoes phacoemulsification in VMKVMCH, Salem is evaluated. The ACD was measured 1 week, 1 month, 3 months and 6 months and1 year after surgery. The actual axial movement of IOL was defined as the root mean square (RMS) of the change in ELP at each visit. Results- A total of 120 eyes of 60 patients were included, and 60 patients (50%) were men. All the patients underwent uneventful surgeries with­out intra-operative or postoperative complica­tions, and returned on time for measurements. The mean age of them was 70.4±7.2 years (range 54 to 78 years). Mean ELP among differ­ent visits of the polished group was more stable than that of the control group.
