Effects of Trichostatin A on the Histone Deacetylases (HDACs), Intrinsic Apoptotic Pathway, p21/Waf1/Cip1, and p53 in Human Neuroblastoma, Glioblastoma, Hepatocellular Carcinoma, and Colon Cancer Cell Lines
Authors: Sanaei Masumeh , Kavoosi Fraidoon
Published: March 2023

Background:  The aberrant and altered patterns of gene expression play an important role in the biology of cancer and tumorigenesis. DNA methylation and histone deacetylation are the most studied epigenetic mechanisms. Histone deacetylase inhibitors (HDACIs) such as valproic acid (VPA) and trichostatin A (TSA) are a group of anticancer compounds for the treatment of solid and hematological cancers. Previously, we reported the effect of two HDACIs, valproic acid (VPA) and TSA, on colon cancer and hepatocellular carcinoma (HCC), respectively. The aim of the current in vitro study is to investigate the effects of TSA on the intrinsic apoptotic pathway, p21/Waf1/Cip1 (p21), p53, and histone deacetylases (HDACs) 1, 2 and 3 in human neuroblastoma LAN-1, glioblastoma GBM-29, HCC SMMC7721, and colon cancer COLO 201 cell lines.
Materials and methods: In this lab-trial study, all three cell lines were seeded at the density of 3 × 105 cells per well and incubated for 24 hours. Then, the cells were treated with TSA based on IC50 values for 24 hours except in the control groups; the control cells were treated with the equal amounts of the DMSO solvent. Subsequently, cell viability, cell apoptosis and gene expression were determined by three techniques including MTT assay, flow cytometry assay, and qRT-PCR.
Results: The result of qRT-PCR indicated that TSA could increase the expression levels of Bid, BimEL, Noxa, p21, and p53 genes and decrease those of Bcl-xL, RIP, Mcl-1, XIAP, HDACs 1, 2 and 3 significantly (P < 0.0001) by which it inhibited cell growth and induced significant cell apoptosis in LAN-1, GBM-29, SMMC7721, and COLO 201 cell lines (p value<0.001).
Conclusion: TSA can affect cell apoptotic via the intrinsic apoptotic pathway in LAN-1, GBM-29, SMMC7721, and COLO 201 cell lines.

Published: March 2023

Acute Disseminated Encephalomyelitis (ADEM) is a monophasic demyelinating disease most often triggered by infection or immunization, though associations with malignancy and stem cell transplant have been described. We described the case of a four-year-old boy with new-onset neurological symptoms associated with ADEM, acute leukemia, and equivocal evidence of Mycoplasma pneumoniae infection. He responded to a short course of antibiotics and chemotherapy for B cell acute lymphoblastic leukemia (B-ALL) that included a prolonged course of high dose steroids with immunosuppressive therapy. This case illustrated a possible association between paraneoplastic ADEM and leukemia in pediatric patients.

Published: March 2023

Background: The antioxidant activity of Bane (Pistacia atlantica) has been proved in different researches. This study evaluated the potential of Bane (Pistacia atlantica) essential oil (as a natural antioxidant) on the oxidative stability of sunflower oil. 
Methods: The essence of Bane was added to sunflower oil at concentrations of 200, 400,600,800, and 1,000 ppm. Tertiary Butyl Hydroquinone (TBHQ) was applied as synthetic antioxidant. All samples with the control were stored at 65 ̊C for 20 days. Gas Chromatography-Mass Spectrometry was used for the essence analysis. The 2,2-diphenyl-1-picrylhydrazyl radical scavenging assay, rancimat, p-anisidine value (P-AnVs), and peroxide value (PV) were determined to assess the efficacy of differecnt concentration of essence (200, 400,600,800, and 1,000 ppm). Data were analyzed by Statistical Analysis System (SAS) version 9 Software.
Results: The essential oil yield was 0.1% v/w. The basic components of essence were monoterpene and sesquiterpene hydrocarbons. Synthetic antioxidant had the highest scavenging activity, followed by the mixture sample. PVs were in the range of 19.56-20.73 milliequivalents (meq)/kg for the treated samples after 20 days, while it was 38.74 on the 20th day for the control. For all treatments, PV was increased with increasing storage time. P-AnVs were 8.58-17.14 for stabilized samples and 18.02 for control sample on the 20th day of storage. In all stages, control sample had the highest P-AnV. For all samples, P-AnV increased as a subject of storage time.
Conclusion: P. atlantica (Bane) essential oil had a stabilizing effect on sunflower oil and can be used as a natural antioxidant to stabilize edible oil during storage.

Importance of Induction Endometritis and Vaginal Cytology in Rat Model: A Narrative Review Article
Authors: Barzegar-Bafrouei Abolfazl , Javdani Moosa
Published: March 2023

Introduction: Endometritis is a female reproductive disease characterized by the inflammation of the endometrial glandular and stromal tissues. It is usually occurred due to uterine contamination with infectious causes. Animal models of clinical endometritis are very important to prevent the incidence and treatment of endometritis. Vaginal cytology method is considered as a golden standard for determining the estrous cycle stage in female rats. The aim of this study was to induce endometritis in a rat model and determine the stages of the estrous cycle of this animal using vaginal cytology method in order to successfully induce this condition in this animal model.
Conclusion: Inflammation changes the production of endometrial cytokines, which may result in menstrual disorders and decreased endometrial reception by impaired endometrial tissue dysfunction. Increased expression of specific cytokines genes such as IL-6, IL-8 and TNF-α can be used to detect the severity and degree of endometritis. Uterine infections are known as a result of damage to the defense mechanisms of the uterine tissue, which are caused by physiological changes in the postpartum period. Another change that occurs in the postpartum period is the increase in the production of reactive oxygen species. The imbalance between the production of reactive oxygen species and its clearance leads to the creation of oxidative stress conditions. On the other hand, there is a significant relationship between inflammatory diseases such as endometritis and oxidative stress. On other hand, by accurately determining the estrous cycle of rats by using vaginal cytology, endometritis can be well induced in this species.

Published: March 2023

Introduction:Doxorubicin is a universal drug in treatment of all types of cancers, which is limited in its use due to various side effects in body tissues, so the present study investigated effect of aerobic exercise and use of curcumin nanomicelles on gene expression of the enzymes (GlutathionePeroxidase) GPX, (Catalase) Cat (Superoxidedismutase) SOD and (Malondialdehyde) MDA was investigated in the heart tissue of BalbC female rats with induced breast cancer in the treatment phase of doxorubicin.
method: This research was practical, it was experimental in terms of control of variables and it was a laboratory in terms of place of implementation. Thirty-six BalbC mice were randomly divided into 6 groups (n=6): healthy, patient, doxorubicin patient, doxorubicin patient and aerobic exercise, doxorubicin patient and nanocurcumin supplement, and doxorubicin patient, aerobic exercise and supplementation. Breast cancer induction was done with MC4-L2 cells. Doxorubicin 2mg/kg was injected subcutaneously 6 times on days 1,7,14,21,28 and 35. Aerobic program consisted of 5 sessions per week for 42 days with an increase in the speed of the treadmill every two weeks, including 14, 16 and 18meters per minute and the use of nanocurcumin at a dose of 100mg/kg.The data collected with SPSS version16 and two-way analysis of variance and for the normality of the frequency distribution with skewness and non-parametric Kolmogorov-Smirnov test were performed with a significance level of P ≤ 0.05.
Results: Six weeks of aerobic training had no effect on the expression of GPX, MDA and SOD genes in the target groups, but it significantly increased the expression of Catgene (P ≤ 0.05). The use of nanocurcurmin supplement for 6 weeks decreased the expression of MDA gene and significantly increased the expression of GPX, SOD and Catgenes. Six weeks of aerobic training along with nanocorcurmin supplementation significantly increased Cat gene expression (P≤0.05), but had no effect on GPX, MDA and SOD gene expression.
Conclusion: Aerobic exercises and the use of nanocurcurmin supplement separately or at the same time can be effective in reducing the cardiac toxicity of doxorubicin in the patients with breast cancer.

Authors: Rahmatinejad Parvin , Past Negin , Mozafari Mohammadreza , Sadrabadi Fatemeh Shahi
Published: March 2023

Introduction: In the recent years, transcranial direct current stimulation (tDCS) has been considered by researchers as one of the possible effective approach in the treatment of major depressive disorder. However, the results of these investigations are often contradictory. According to this, the purpose of this study was to determine the effectiveness of tDCS in reducing symptoms of people with major depressive disorder.
Methods: In the sham-controlled randomized trial, twenty people with major depressive disorder referred to a private psychiatric clinic in Tehran City, Iran. They were selected by convenience sampling and divided into the intervention and control groups by randomized block design. tDCS was administered 2 mA, 20 minutes per session, for 10 sessions, 3 days per week. Immediately after, and one month after the intervention, the scores of the two groups were assessed in the Hamilton Depression Rating Scale and Beck Depression Inventory. The data were analyzed using SPSS version 16 software and using statistical methods of repeated analysis of variance and independent and dependent t-test.
Results: The results of repeated analysis of variance for Hamilton (F = 43.5 and P = 0.017) and Beck (F = 125.12 and P = 0.022) depression scores showed the significance of the interaction effect of time (four stages of measurement) and group membership (experiment and control) (P < 0.05). In depression scores in both Hamilton and Beck scales in the experimental group in the intervention stages (Hamilton scale, P = 0.019, Beck scale = P = 0.017) and follow-up (Hamilton scale, P = 0.01, Beck scale = P = 0.03) was significantly reduced compared to the control group.
Conclusion: The results of this study confirmed the effectiveness of tDCS in reducing symptoms of major depressive disorder. More clinical trials are needed to prove the effectiveness of tDCS compared to a variety of treatments.

Introduction: This prospective analytical study was conducted with the aim of determining the prevalence, severity and factors affecting the short-term complications of implant surgery.
Methods: In a descriptive cross sectional study, patients referring to the implant department of Tehran University of Medical Science from 2020 to 2021 were included (292 implants in 152 patients). Patients underwent Simple implant placement without hard and/or soft tissue grafts were included. After 7 and 14 days, ecchymosis, bleeding, swelling, delayed wound healing, infection, and trismus were recorded. Pain, the most common outcome after surgeries was assessed based on the number of days the patient had pain, the number of analgesics used and the severity of pain (Numeric pain intensity scale) using SPSS software version 16. The relationship between complications and measured variables was examined by logestic regression analyses.
Results: The most common complications on the 7th day follow up were ecchymosis (3.9%) and delayed wound healing (3.9%). The mean pain score was 1.61 ± 1.32. No patient had pain more than 3 days after surgery. The mean number of analgesic used was 2.23 ± 1.82. Based on logistic regression analyses, only patient age and the number of days of analgesics use showed a significant relationship with the number of analgesics used (P˂0.001). Neither the level of expertise of the surgeon nor the patients' gender had nosignificant effect on the degree of complications pain and amount of patient pain and the consumption of analgesics (P˃0.05). Patients with poor oral hygiene used more analgesics in comparison to patients with favorable oral hygiene.
Conclusion: The overall prevalence of post-operative complications after simple implant surgeries was less than 4%. The older the patient, the higher the consumption of analgesics.

Authors: Mirhosseini Naser Ali , Mirhosseini Shima , Aflatoonian Majid , Saeida-Ardekani Maryam
Published: March 2023

Background: Conversion of glucose-6-phosphate to glucose is the final step in both glycogenolysis and gluconeogenesis. In glycogen storage disease type Ia (GSD type Ia), decreased activity of the enzyme glucose6-phosphatase leads to an increased concentration of glucose-6- phosphate within the hepatocytes and shunting into alternative pathway with the following consequences: hyperlactatemia, hyperuricemia and hypertriglyceridemia. Patients develop hypoglycemia within 3 to 4 hours after a meal.
Case Report: We reported four patients with GSD type Ia with different clinical manifestations such as hypoglycemia, hepatomegaly, lactic acidosis, hyperchylomicronemia, and hyperuricemia and also described their prognosis.
Conclusion: Previously, many children with GSD Ia died in infancy or early childhood. Recurrent severe hypoglycemia can cause brain damage, but the prognosis has improved dramatically with early diagnosis and long term maintenance of optimal metabolic control.

A publicidade e o mestre do gozo
Authors: Kehl Maria Rita
Published: March 2023

O mundo capitalista, em sua fase consumista, é organizado pelo fetiche. O que já estava em Marx, com o conceito de fetiche da mercadoria, passa a incluir a dimensão freudiana do fetiche, que diz respeito às modalidades perversas de gozo. A publicidade acrescenta às mercadorias o fetiche da imagem e da marca, que se oferecem à identificação de todos, independentemente do poder aquisitivo. Neste mundo, os publicitários seriam os mestres do gozo, cujo poder se assemelha ao fascínio que os perversos exercem sobre os neuróticos comuns.

Abstrat:

The capitalistic world, in its consumist phase, is organized by the fetish. What was already in Marx, as the concept of merchandise fetish, now includes the Freudian dimension of fetish that says respect to the perverse modalities of pleasure. Publicity adds to merchandise the fetish of image and brand, which are offered to the identification of all, independent of purchasing power. In this world, publicists would be the masters of pleasure whose power resembles that one that the perverse exert on the common neurotics.

Ethos, enunciação, mídia Semiótica do ethos
Authors: Soulez Guillaume
Published: March 2023

A noção de etos na Retórica de Aristóteles – a idéia de que qualquer orador cria uma imagem se si próprio através do seu discurso – pode os ajudar a analisar o discurso público de apresentadores, convidados, jornalistas ou políticos no rádio ou na televisão. Sugerimos aqui que, ao lado do estudo da enunciação, a semiótica nos faz entender como o ethos funciona do ponto de vista da audiência e, portanto, como audiências consomem o discurso público na mídia por meio do ethos.

Abstract:

Aristotle's notion of ethos in his Rhetoric – the idea that any orator creates an image of himself through his discourse – can help us analyze the public discourse of hosts, guests, journalists or politicians on radio and television. We try here to suggest that linked to the study of enunciation, semiotics help us understand how ethos works from the point of view of the audience, and therefore how audiences consume the public discourse on media through ethos.

Dispositivos de telecura e contratos da salvação
Authors: Neto Antônio Fausto
Published: March 2023

Os campos religioso e midiático articulam-se em torno de dispositivos de operações discursivas gerando uma modalidade de “fazer religião”. Uma das características do modelo interativo das teleemissões é eleger problemáticas situacionais das pessoas, transformando-as em demandas e soluções mediante estratégias de cura e de salvação. A noção de saúde está associada às observâncias dos “contratos de leitura” que situam o fiel paciente em uma estrutura de linguagem enclausurada. Aí permanece, portanto, em um “regime simbólico” que o mantém em novas situações de enfermidades.

Palavras-chave: Dispositivo; cura; telerreligião; saúde; enunciação.

ABSTRACT

Media and religion fields are articulated by discursive operations mechanisms which generate a way of “making religion”. One of the characteristics of the interactive model of tele broadcasts is to elect people’s situational problems, turning them into demands and solutions, through strategies of cure and salvation. The notion of health is associated to the close observation of “reading contracts” that situate the faithful patient within an enclosed language structure. The viewer is thus kept within a “symbolical re-gime” which remains in any new infirmity situations.

Published: March 2023

RESUMO

Este artigo aborda as transformações da concepção de corpo da sociedade disciplinar – Foucault – para a de controle – Deleuze –, com base na análise das representações de corpo presentes em anúncios3 de medicamentos e cosméticos em dois momentos da publicidade brasileira: a década de 1920 e a atualidade – segunda metade da década de 1990 até o presente momento. Embora os cuidados com o corpo tenham se transformado significativamente ao longo do século passado, observa-se, nas campanhas e peças analisadas, que a noção de imperfeição e a necessidade de aprimoramento permanecem como traço constitutivo do imaginário de corpo.

Palavras-chave: Corpo; publicidade brasileira; medicamento; cosmético.

ABSTRACT

This article deals with the transformations undergone by the conception of body, from the disciplinary society – Foucault – to the society of control – Deleuze –, using as our starting point representations of the body found in advertisements for medicines and cosmetics in two moments of Brazilian publicity: the 1920’s and now – from the second half of the 1990’s to the present day. In spite of significant changes in body care throughout the 20th century, we can notice in the campaigns and advertisements under analysis that the notions of imperfection and the need of improvement

are still constituent features in the cultural imaging of the body.

Sex estimation using measurements of the proximal femur in a historical population from Poland
Authors: Wysocka Joanna , Cieślik Agata I. , Danel Dariusz P.
Published: March 2023

Sex estimation is one of the most important components in assessing the biological profile of an individual. In an archaeological context, the pelvis, which is the most dimorphic part of the skeleton, is often poorly preserved, which can cause an inability to use morphological sex estimation methods. Therefore, alternative methods are required in such cases. Because the utility of the metric methods based on the femur measurement has been confirmed, and the bone is usually available for examination due to its good preservation, developing methods using the landmarks of the femur could have important implications in sex estimation.  
This study aimed to derive a discriminant function equation for a Polish archaeological population based on measurements of the proximal end of the femur.  
The study sample included individuals from a medieval cemetery in Milicz (n = 62) and an early modern necropolis at Czysty Square in Wrocław, Poland (n = 162). The analysis included seven measurements collected from the right and left proximal femora. To estimate the reproducibility of the measurements, intra-and interobserver errors and reliability coefficients were calculated. Subsequently, univariate and stepwise discriminant analyses were performed, and the sex sectioning points and equations were proposed.  
No differences were observed between measurements of the right and left femora. The results indicated a high utility and reproducibility of the FHD measurement (regardless whether left or right femur was measured). The discriminant equations for sex estimation reached an accuracy of 83.0–92.3%, which implies the utility of the function on Polish historical populations when the other methods for sex estimation cannot be used.

Authors: Narayanan Nishant K
Published: March 2023

Am Beispiel des Romans Jessica, 30. der österreichsichen Autorin MARLENE STREERUWITZ wird in diesem Beitrag das mehrdeutige und zugleich dynamische Frauenbild in der Gegenwartsliteratur gezeigt. Hierbei wird einerseits auf die Transformationen der Protagonistin Jessica, andererseits auf ihre Versuche unsicherer Überschreitungen und hierdurch ausgelöste Konflikte eingegangen. Außerdem hat der Beitrag das Anliegen, das Sprachdesign von STREEUWITZ unter die Lupe zu nehmen und exemplarisch als ein Diskursmittel zur Konstitution von weiblicher Geschlechtsidentität innerhalb der ambivalenten Konstellation von Ordnung bzw. Unordnung der gesellschaftlichen Machtverhältnisse und -strukturen zu analysieren.
Zum Drittpersonalpronomen im Chinesischen und im Deutschen
Authors: Duan Jiye , Aptacy Jarosław
Published: March 2023

Das Ziel des Artikels ist es, Formen und Funktionen von Personalpronomen der dritten Person, insbesondere des femininen Pronomens, im Chinesischen und Deutschen zu vergleichen. Da in China die Diskussion um die spezifische Form des weiblichen Pro-nomens relativ neu ist und in einigen Kreisen noch andauert, wird die Entwicklung dieses Pronomens im Laufe der Jahrhunderte aus der Gender-Perspektive dargestellt. Der Streitpunkt war / ist in erster Linie das Schriftzeichen für dieses Pronomen, aber es gab auch Stimmen, die eine bestimmte Lautform vorschlugen. Da im Deutschen Pronomen der dritten Person je nach Genus unterschiedliche Formen haben, sind den Autoren dieses Artikels ähnliche Diskussionen im deutschsprachigen Raum nicht bekannt. Der zweite Teil des Artikels vergleicht die deiktischen und anaphorischen Funktionen von Pronomen in den beiden Sprachen.
Okkasionelle up-to-date-Phraseologismen auf der Folie der usuellen.

Modifizierungen bzw. Abwandlungen der Phraseologismen werden zusehends zum neuen Forschungsparadigma der Sprachwissenschaft. Die hier zu besprechende Fall-studie ist nur eine von ihresgleichen. Es fragt sich allerdings, ob Phraseologismen tatsäch-lich modifiziert bzw. abgewandelt werden können, wenn die Konstanz deren formaler und/oder lexikalischer Elemente nach wie vor als definitorisch ausschlaggebend hingestellt werden soll. Im vorliegenden Rezensionsartikel wird dafür plädiert, dass die althergebrachten stehenden Wendungen weiterhin unangetastet bleiben sollen. CHLEBDA (2020) zufolge stellen sie einen „Vorrat an sprachlichen Weltbildern“ dar, die der Up-to-date-Erschließung neuer Sprachbilder dienlich sein sollen. So bleibt – um ein Beispiel aus CZYŻEWSKA (2011) zu bringen – das Phrasem Berge versetzen nach wie vor intakt als Folie für eine neue Hinter-fragung der Welt erhalten. Früher waren es nämlich die Riesen, die sich daran schlechter-dings der Demonstration ihrer Kraft halber versuchten. Nunmehr steckt immer ein Geschäft dahinter: Wenn man Berge versetzt, ist einer garantiert etwa aus Gold [oder Uran…] dabei.

Typically chemical processes have significant nonlinear dynamics, but despite this, industry is conventionally still using PID-based regulatory control systems. Moreover, process units are interconnected, in terms of inlet and outlet material/energy flows, to other neighboring units, thus their dynamic behavior is strongly influenced by these connections and, as a consequence, conventional control systems performance often proves to be poor. This paper proposes a hybrid fuzzy PID control logic, whose tuning parameters are provided in real time. The fuzzy controller tuning is made on the basis of Mamdani controller, also exploiting the results coming from an identification procedure that is carried on when an unmeasured step disturbance of any shape affects the process behavior. In addition, this paper compares a fuzzy logic based PID with PID regulators whose tuning is performed by standard and well-known methods. In some cases the proposed tuning methodology ensures a control performance that is comparable to that guaranteed by simpler and more common tuning methods. However, in case of dynamic changes in the parameters of the controlled system, conventionally tuned PID controllers do not show to be robust enough, thus suggesting that fuzzy logic based PIDs are definitively more reliable and effective.
Induced polarization effect in reservoir rocks and its modeling based on generalized effective-medium theory
Authors: Burtman Vladimir , Zhdanov Michael
Published: March 2023

One of the major tasks of the petroleum resource-efficient technologies (pREFFIT) is the development and improvement of the methods of exploration for energy resources. This review paper summarizes the results of the research on induced polarization (IP) effect in reservoir rocks conducted by the University of Utah Consortium for Electromagnetic Modeling and Inversion (CEMI) and TechnoImaging. The electrical IP effectin hydrocarbon (HC) bearing reservoir rocks having nonmetallic minerals is usually associated with membrane polarization, which is caused by a variation in the mobility of the ions throughout the rock structure. This mobility is related to the size and shape of the pores filled with electrolyte and the double electrical layers. We have studied the IP response of multiphase porous systems by conducting complex resistivity (CR) frequency-domain IP measurements for two different groups of samples: sands and sandstones containing salt water in pores and those whose unsaturated pores were filled with synthetic oil.We have also studied selected carbonate reservoir formations, typical of some major HC deposits. The generalized effective-medium theory of induced polarization (GEMTIP) was used to analyze the IP parameters of the measured responses. This paper presents a conceptual model of polarizing clusters to explain the observed IP phenomena. The results of this study show that the HC bearing sands and sandstone samples and carbonate rocks are characterized by a significant IP response. These experimental observations, compared with the theoretical modeling based on the GEMTIP approach, confirm earlier geophysical experiments with the application of the IP method for HC exploration.
The rationale for alternative fertilization: Equilibrium isotherm, kinetics and mass transfer analysis for urea-nitrogen adsorption from cow urine

Published: March 2023

In an effort to minimize the loss of urea-N through volatilization and concurrently recover urea in a usable form from cow urine, adsorption experiments using bamboo-based activated carbon were performed. Batch studies were undertaken to evaluate the effect of initial concentration, sorption time and temperature on the variation in urea uptake capacity of the prepared carbon. Equilibrium data were tested against various isotherms, kinetics and mass transfer models. The Langmuir monolayer sorption was found to be 146.12 mg.g−1 with nearly 90% urea recovery attained. The process was found to be reversible as seen through regeneration experiments. Thermodynamic parameters indicated that urea sorption was physical, spontaneous and exothermic in nature. Kinetic studies revealed that the rate of urea uptake was limited by both surface adsorption and intra-particle diffusion. It was concluded that the mass transfer of urea molecules over the activated carbon was governed by film diffusion at all concentrations examined.

Natural aluminosilicate activated by a heat/acid treatment, followed by modification with uric acid was used to remove sulfates for treatment of wastewater effluent. Natural aluminosilicates were studied in every stage of the modification (namely activation, modification with uric acid, and after sulfates absorption) by scanning electron microscopy (SEM), spectroscopy X-ray diffraction (XRD), energy dispersive spectroscopy (EDS),surface area (BET), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), and Z potential. More than 60% of the initial concentration of sulfates (500 mg/l) was removed with the natural aluminosilicate modified with uric acid. Absorption isotherms rendered a mechanism with contributions from both Langmuir and Freundlich mechanisms. This study opens the path for the use of natural and abundant local material to remove sulfates using a modifier already present in wastewater effluents as contaminant.

Published: March 2023

To achieve short mass transfer zones that enable arsenic removal under high hydraulic loading rates and short empty bed contact times needed for small point-of-use packed bed applications, hybrid media was developed and tested. Cross-linked macroporous glycidyl methacrylate copolymer support media was synthetized, amino modified and in-situ impregnated by goethite nanoparticles via an oxidative deposition in a hydrophilic/hydrophobic (water/xylene) system. The media properties were characterized via scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDS), X-ray diffraction (XRD), and surface area analysis. Arsenic removal capabilities of the hybrid goethite impregnated media were evaluated by conducting batch sorption tests, developing isotherms and simulating the breakthrough curve with a pore surface diffusion model (PSDM), after being verified by a short bed column (SBC) test. The high porous media (ep ≈ 0.7) contained ∼16% of iron and exhibited Freundlich adsorption capacity parameter of K ≈ 369 (μg g−1)(L μg−1)1/n and Freundlich intensity parameter of 1/n ≈ 0.54. Without engaging in taxing pilot scale testing, the PSDM was able to provide a good prediction of the media’s capacity and intraparticle mass transport properties under high hydraulic loading rates.

New silver containing sorbents, based on mineral carriers, such as alumina and silica systems with a meso- and macro- porous structure, have a higher mechanical resistance and, hydrophilic and hydrophobic chemical composition of the surface. These sorbents are easy to find and relatively inexpensive, compared to their known equivalents. They are furthermore characterised by high specific surface and simple preparation, whilst the addition of silver considerably increases their antiseptic activity. The results of research of the physical, chemical and biological properties of the developed substances, as well as bio-comparability of sorbents with biological tissues, are presented in this paper. The modified material acts simultaneously as the carrier for active substances to the area of therapeutic application and as a sorbent used to remove toxic agents from such areas. This approach led us to modify the sorbent, and prolong the delivery of substances such as silver, as an effective antibacterial and antimycotic agent.
