Correlation of palatal anatomic characteristics with dermatoglyphic heterogeneity in different growth patterns.

AIM AND OBJECTIVE: The study aimed to explore the correlation between dermatoglyphic patterns and quantitative palatal anatomic variables in individuals with different growth patterns. MATERIALS AND METHOD: A cross-sectional study was conducted involving 126 healthy patients aged 17-25 years. Participants were divided into three groups based on growth patterns: average, vertical, and horizontal. Dermatoglyphic patterns were recorded using an optical fingerprint sensor, and palatal characteristics were measured using digital software. Palatal characteristics, including intercanine width, intermolar width, and palatal depth, were measured using digital software. The results were statistically analyzed. RESULTS: Significant differences were observed in ridge counts among the three growth patterns. The average growth pattern showed lower ridge counts compared to the vertical and horizontal growth patterns. Dermatoglyphic patterns, such as double loops and tented arches, were significantly higher in the horizontal growth pattern. Weak correlations were found between certain dermatoglyphic patterns and palatal characteristics, with simple arch patterns showing a negative correlation with inter-canine width and symmetrical whorl patterns showing a positive correlation with palatal depth. Loop patterns, spiral patterns, double loop patterns, symmetrical whorl, and simple arch patterns were significant predictors of growth patterns. CONCLUSION: This study revealed distinct dermatoglyphic patterns and ridge counts among individuals with different growth patterns. Weak correlations were observed between dermatoglyphic patterns and palatal characteristics. However, the predictive value of dermatoglyphics for skeletal malocclusion requires further investigation. Understanding the relationships between dermatoglyphic patterns and craniofacial growth can provide valuable insights into genetic and developmental factors affecting dental and orthodontic conditions.

Perspectives of Childhood Cancer Survivors as Young Adults: a Qualitative Study of Illness Education Resources and Unmet Information Needs.

This study investigates the resources used by childhood cancer survivors (CCS) to learn about their cancer histories and evaluates if CCS feel these resources prepare them to manage their health needs as young adults. Young adult participants (aged 18-30 years) were diagnosed with cancer at ≤ 10 years and recruited by word of mouth and from social media and/or non-profit organizations and completed semi-structured interviews. A descriptive thematic analysis guided by an essentialist/realist paradigm combined inductive and deductive approaches to identify key themes. Fourteen participants were interviewed, and six key themes were identified: (1) CCS are aware of general cancer history (age at diagnosis, treating hospital, cancer type), (2) CCS are unaware of treatment regimen (medications and duration), (3) CCS want to learn more about their treatment regimens and (4) potential late effects of treatment, (5) CCS use diverse resources to learn about their cancer histories and potential late effects, and (6) survivors' interests to learn about their cancer histories change over time. Limited knowledge of their cancer treatments leaves some CCS unprepared to manage their health needs as young adults or to address potential risk of late effects. CCS recognize their limited knowledge, but the resources available to them fall short of their information needs. Identifying the shortcomings of resources used by CCS provides evidence for how resources need to be improved to meet survivors' cancer education needs.

Fluoride Geochemistry and Exposure Risk Through Groundwater Sources in Northeastern Parts of Rajasthan, India.

Exposure to fluoride concentrations above a threshold of 1.5 mg/L can cause joint pains, restricted mobility, skeletal and dental fluorosis. This study aims to determine the hydrochemical evolution of the fluoride-rich groundwater and estimate the risk of fluoride exposure to the residents of semi-arid northeastern part of Rajasthan, India. The methodology involves measurement of fluoride and other ionic concentrations in groundwater using ion chromatography, followed by an estimation of the cumulative density function and fluorosis risk. The fluoride concentration in water samples varied from 0.04 to 8.2 mg/L with 85% samples falling above the permissible limit. The empirical cumulative density function was used to estimate the percentage and degree of health risks associated with the consumption of F- contaminated water. It is found that 55% of the samples indicate risk of dental fluorosis, 42% indicate risk of deformities to knee and hip bones, and 18% indicate risk of crippling fluorosis. In addition, instances of high nitrate concentrations above the permissible limit of 45 mg/L are also found in 13% of samples. The fluoride rich groundwater is mainly associated with the Na-HCO3-Cl type water facies while low fluoride groundwater shows varied chemical facies. The saturation index values indicate a high probability of a further increase in F- concentration in groundwater of this region. The calculated fluoride exposure risk for the general public in the study area is 3-6 times higher than the allowed limit of 0.05 mg/kg/day. Based on the results of this study, a fluorosis index map was prepared for the study area. The northern and northeastern parts are less prone to fluorosis, whereas the south-central and southwestern parts are highly vulnerable to fluorosis. The inferences from this study help to prioritize the regions that need immediate attention for remediation.

Osseous sarcoid with lytic lesions in skull.

Sarcoidosis bone is uncommon, and involvement of the skull is exceptionally rare. We present a 65-year-old obese female who presented with a 2-month history of dryness of mouth, polyuria, fatigue, and anorexia. She had generalized lymphadenopathy, organomegaly, and hypercalcemia, and a skeletal survey revealed extensive osteolytic lesions in the skull and phalanges. Both lymph node biopsy from the cervical lymph node and bone marrow examination revealed non-caseating granulomas, suggesting sarcoidosis. She was started on 1 mg/kg oral corticosteroids; during a follow-up of 6 months, she achieved normocalcemia; however, the punched-out lesions in the skull remained unchanged. This case reiterates several important issues that all lymphadenopathy in emerging nations may not be tubercular, and presence of osteolytic lesions in skull are unusual for sarcoid, at an elderly age, necessitates evaluation for more common etiologies like metastases and myeloma. Finally, patients with osseous sarcoid should be on a close follow-up since due to the rarity of this presentation, no definite consensus on the management of such cases exists in the literature.

Effect of Deep Margin Elevation on the Pulpal and Periodontal Health of Teeth: A Systematic Review.

OBJECTIVE: To systematically evaluate the clinical performance of deep margin elevation (DME) technique in terms of pulpal and periodontal health of teeth. METHODS AND MATERIALS: An exploratory search was performed in PubMed, Scopus, Embase, Web of Science, and Google Scholar up to September 2023 by two authors independently. This systematic review was performed in accordance with Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Systematic Reviews (PRISMA-SR) and registered with PROSPERO-CRD42022382082. A custom-designed spreadsheet was used to extract the data. The quality of each study was evaluated by means of the Joanna Briggs Institute (JBI) risk of bias (ROB) tool specific for each study design. RESULTS: A total of 5363 articles was obtained through an electronic database search, the grey literature, and a hand search. 2814 duplicates were removed, and an additional 2535 articles were also removed, as they did not meet the eligibility criteria. Following the screening of titles and abstracts, 16 articles were selected for full text reading, from which 10 articles were included for final qualitative analysis. DME was predominantly done with resin-based composite or glass ionomer cement (GIC). Parameters like periodontal pocket depth and bleeding on probing were within normal limits in all teeth with DME. Only one study checked the histological outcome and concluded that DME had no negative effect on the periodontium. Most of the studies used indirect restoration (composite/lithium disilicate/Emax) over the DME layer. The follow-up period ranged between 6 months and 12 years. CONCLUSION: The level of evidence of this review is low, but DME was successful in all teeth, without any deleterious effect on pulp and periodontium.

Lipase from marine strain using cooked sunflower oil waste: production optimization and application for hydrolysis and thermodynamic studies.

The marine strain Pseudomonas otitidis was isolated to hydrolyze the cooked sunflower oil (CSO) followed by the production of lipase. The optimum culture conditions for the maximum lipase production were determined using Plackett-Burman design and response surface methodology. The maximum lipase production, 1,980 U/ml was achieved at the optimum culture conditions. After purification, an 8.4-fold purity of lipase with specific activity of 5,647 U/mg protein and molecular mass of 39 kDa was obtained. The purified lipase was stable at pH 5.0-9.0 and temperature 30-80 °C. Ca(2+) and Triton X-100 showed stimulatory effect on the lipase activity. The purified lipase was highly stable in the non-polar solvents. The functional groups of the lipase were determined by Fourier transform-infrared (FT-IR) spectroscopy. The purified lipase showed higher hydrolytic activity towards CSO over the other cooked oil wastes. About 92.3 % of the CSO hydrolysis was observed by the lipase at the optimum time 3 h, pH 7.5 and temperature 35 °C. The hydrolysis of CSO obeyed pseudo first order rate kinetic model. The thermodynamic properties of the lipase hydrolysis were studied using the classical Van't Hoff equation. The hydrolysis of CSO was confirmed by FT-IR studies.

A novel cyano derivative of 11-keto-ß-boswellic acid causes apoptotic death by disrupting PI3K/AKT/Hsp-90 cascade, mitochondrial integrity, and other cell survival signaling events in HL-60 cells.

Intervention of apoptosis is a promising strategy for discovery of novel anti-cancer therapeutics. In this study, we examined the ability of a novel cyano derivative of 11-keto-ß-boswellic acid, that is, butyl 2-cyano-3,11-dioxours-1,12-dien-24-oate (BCDD) to induce apoptosis in cancer cells. BCDD inhibited cell proliferation with 48 h IC(50) of 0.67 µM in HL-60, 1 µM in Molt4, and 1.5 µM in THP1 cells. The mechanism of cell death was investigated in HL-60 cells where it caused apoptosis by acting against several potential apoptosis suppressive targets. It inhibited phosphatidylinositol-3-kinase (PI3K)/AKT activity, NF-κB, Hsp-90, and survivin which may enhance the sensitivity of cells to apoptosis. Also, BCDD decreased the activity of Bid and Bax in cytosol, caused ΔΨ(mt) loss, releasing pro-apoptotic cytochrome c, SMAC/DIABLO leading to caspase-9-mediated down stream activation of caspase-3, ICAD, and PARP1 cleavage. Translocation of apoptotis-inducing factor (AIF) from mitochondria to the nucleus indicated some caspases-independent apoptosis. Though it upregulated DR-5 and caspase-8, the caspase inhibitor yet had no effect on apoptosis as against 75% inhibition by caspase-9 inhibitor. Attempts were made to examine any acclaimed role of AIF in the activation of caspase-8 using siRNA where it had no effect on caspase-8 activity while the Bax-siRNA inhibited caspase-3 activation suggesting predominance of intrinsic signaling. Our studies thus demonstrated that BCDD exerts multi-focal action in cancer cells while it required 10-fold higher the concentration to produce cytotoxicity in normal human PBMC and gingival cell line, and therefore, may find usefulness in the management of human leukemia.

Fit testing and comfort evaluation of prophylactic dressing use for healthcare workers under N95/P2 respirators in one health service district in Australia.

BACKGROUND: This study evaluated the use of prophylactic dressings (silicone foam, silicone tape, hydrocolloid) under N95/P2 respirators to determine which dressings fit successfully. AIM: The aim was to develop a health service protocol for one state in Australia. METHODS: Data were collected during August and September 2021 as part of the Respiratory Protection Programme on 600 health workers using three types of prophylactic dressings. Five different types of respirators were used. Participant healthcare workers rated comfort on a four-point Likert scale. RESULTS: Successful fit was achieved by 63.6% of the respirator-dressing combinations. The best-performing respirator-dressing combination was the Trident® respirator with dressing Mepilex® Lite silicone foam (90.2% pass rate). High pass rates were found in the Trident® respirator with Mepilex® Border Lite with SofSicure silicone tape (79.1%); the 3M™ 1860 respirator with Mepilex® Border Lite with SofSicure silicone tape (74%); and the BSN orange duckbill respirator with Mepilex® Lite silicone foam (69.8%). The poorest-performing combination was the BYD™ respirator with Mepilex® Border Lite with SofSicure silicone tape (25.9% pass rate). Uncorrected chi-squared tests for association revealed significant associations between dressing type and outcome (P=0.004) and respirator type and outcome (P<0.001). Most respondents (82%) found the dressing combination markedly comfortable. CONCLUSIONS: When using prophylactic dressings under N95/P2 respirators, it is necessary to perform a fit test. In this study Trident® respirators had the highest probability of successful fit, while BYD™ respirators had the lowest. Combining Trident® respirators with Mepilex® Lite dressing was optimal. Most participants reported greater comfort with the dressings under the respirators.

Transferrin-conjugated liposomal system for improved delivery of 5-fluorouracil to brain.

The objective of this study is to achieve the enhanced delivery of 5-fluorouracil to brain through transferrin-coupled liposomes. 5-Fluorouracil-loaded liposomes were prepared by cast film method and characterized for particle size, shape, percent encapsulation efficiency and in vitro drug release. Biodistribution studies were carried out with the help of radiolabelled 5-fluorouracil. 5-Fluorouracil was labelled with (99m)Tc-DTPA by oxidation-reduction method using stannous chloride and optimized for labelling parameters to get a high labelling efficiency. The in vitro stability was determined to check the efficiency of a system to find out the suitability of the radiolabelled system for in vivo studies. (99m)Tc-DTPA-labelled 5-fluorouracil bearing non-coupled and coupled liposomes were administered intravenously and biodistribution studies were performed. The distribution of 5-fluorouracil via non-coupled and coupled liposomes was determined in various organs, such as lungs, liver, kidneys, spleen and brain, by measuring the radioactivity using a gamma scintillation unit. The results of in vivo studies confirmed a selective uptake of the transferrin-coupled liposomes from the brain capillary endothelial cells. An average of 10-fold increase in the brain uptake of the drug was observed after the liposomal delivery of 5-fluorouracil, while the transferrin-coupled liposomes caused a 17-fold increase in the brain uptake of 5-fluorouracil. Therefore, it can be concluded that transferrin-coupled liposomes enhance the brain uptake of the drug, like 5-fluorouracil.

Design and development of a mucoadhesive buccal film bearing progesterone.

The purpose of this research was to develop and evaluate mucoadhesive films for buccal administration of progesterone using film-forming and mucoadhesive polymers. Buccal films of chitosan bearing progesterone were prepared by solvent casting technique. The films have been evaluated in terms of film weight, thickness, density, surface pH, FT-IR, X-ray diffraction analysis, bioadhesion, swelling properties, in vitro drug release and in vivo studies. It was found that the film formulations of 2 cm2 size having weight in the range of 239 +/- 0.32 to 290 +/- 3.23 mg and film thickness were in the range of 0.49 +/- 0.21 to 0.60 +/- 0.26 mm. Density of the films was found to be 0.108 to 0.139 g/mL. Drug content was found to be uniform in a range of 9.21 +/- 0.051 to 9.67 +/- 0.086 mg/cm2 for formulation F1 to F4. Maximum bioadhesion force was recorded for PVP buccal films (formulation F2) i.e. 0.45 +/- 0.53 N as compared to other films. In vitro residence time was in range of 1.85 +/- 0.08 to 8.94 +/- 0.08 h. The drug release studies revealed that formulations follows non-fickian diffusion. In vivo residence time data confirmed that none of the polymers detached from the oral mucosa over the study period, which indicated that the bioadhesion values of all polymers were satisfactory to retain the film on the buccal mucosa. These mucoadhesive formulations could offer many advantages in comparison to traditional treatments and their efficacy as an effective contraception is assessed.

The role of antibiotic prophylaxis in mesh repair of primary inguinal hernias using prolene hernia system: a randomized prospective double-blind control trial.

Antibiotic prophylaxis is being commonly used in mesh repair of inguinal hernia but its role has been questioned in a recent Cochrane analysis performed in 2003. Routine use of antibiotic prophylaxis in mesh repair of inguinal hernia can lead to bacterial resistance and increase in cost. In a present double-blind placebo controlled trial involving 120 patients undergoing inguinal hernia repair using prolene hernia system, we did not find any benefit of the routine use of antibiotic prophylaxis in terms of wound infection rate.

Time and pH dependent colon specific, pulsatile delivery of theophylline for nocturnal asthma.

In this study, investigation of an oral colon specific, pulsatile device to achieve time and/or site specific release of theophylline, based on chronopharmaceutical consideration. The basic design consists of an insoluble hard gelatin capsule body, filled with eudragit microcapsules of theophylline and sealed with a hydrogel plug. The entire device was enteric coated, so that the variability in gastric emptying time can be overcome and a colon-specific release can be achieved. The theophylline microcapsules were prepared in four batches, with Eudragit L-100 and S-100 (1:2) by varying drug to polymer ratio and evaluated for the particle size, drug content and in vitro release profile and from the obtained results; one better formulation was selected for further fabrication of pulsatile capsule. Different hydrogel polymers were used as plugs, to maintain a suitable lag period and it was found that the drug release was controlled by the proportion of polymers used. In vitro release studies of pulsatile device revealed that, increasing the hydrophilic polymer content resulted in delayed release of theophylline from microcapsules. The gamma scintigraphic study pointed out the capability of the system to release drug in lower parts of GIT after a programmed lag time for nocturnal asthma. Programmable pulsatile, colon-specific release has been achieved from a capsule device over a 2-24h period, consistent with the demands of chronotherapeutic drug delivery.

Transdermal atenolol releasing system: an approach towards its development.

A polymer matrix system for transdermal delivery of atenolol was developed for its prolonged and controlled release using different ratios of ethylcellulose and hydroxypropyl methylcellulose. These polymeric matrix films were characterized for thickness, tensile strength, moisture content and drug content. They were also studied for in vitro drug release and in vitro drug skin permeation. The drug release from the films was found to be Fickian diffusion type and exhibiting linear relationship between drug release (Q) vs. square root of time (t0.5). The in vitro skin permeation of drug from transdermal drug delivery system (TDDS) was evaluated using dermatomed pig skin. The product which shows in vitro drug skin permeation near to 64 mcg/h/ml was selected for in vivo studies. The in vivo studies revealed that Ma EC HPMC 46 is most effective among the other polymeric matrix TDDS. The AUC0-28 with Ma EC HPMC 46 was better than orally administered conventional doses at twelve hours interval (AUC0-28 1587 ng h/ml) as well as no trough and peaks in drug plasma level was recorded with TDDS. Hence, it could be concluded that the designed polymeric matrix TDDS of atenolol could be used successfully for effective and prolonged delivery of atenolol. However, it further demands exploration in clinic, an insight vision towards the development of TDDS for commercial use.

Once daily bioadhesive vaginal clotrimazole tablets: design and evaluation.

In this study, a bioadhesive dosage form of clotrimazole was designed using a combination of bioadhesive polymers Carbopol 934P, sodium carboxymethyl cellulose and sodium alginate in different ratios. The bioadhesive strength was evaluated by measuring the force required to detach the tablets from porcine vaginal mucosal membrane. The strong interaction between polymer and mucus lining of the tissue helps increase the contact time and permits localization of activity. Carbopol 934P showed maximum bioadhesion and required maximum force for detachment; the force required for detachment was directly proportional to its content. The formulations were tested for their swelling behavior using the agar gel plate method. The swelling index was a function of the concentration of the hydrophilic polymer and the formulations containing Carbopol 934P and sodium carboxymethyl cellulose were found to swell to a greater extent than those containing Carbopol and sodium alginate. In vitro release studies showed that the batch consisting of 2:1 ratio of Carbopol 934P/sodium alginate (batch C3) released clotrimazole over 24 h. The similarity factor showed that the dissolution profiles of fresh and aged tablets were similar, suggesting good stability of vaginal tablets prepared using a combination of Carbopol 934P and sodium alginate.

Transferrin coupled liposomes as drug delivery carriers for brain targeting of 5-florouracil.

Diseases and disorders of the brain are extremely difficult to treat pharmacologically because most drugs are unable to pass across the blood--brain barriers. Complex multi-strand tight junctions between adjacent cerebral endothelial cells and between choroid plexus epithelial cells form a physical barrier and prevent the passage of water soluble drugs from the blood into the brain, whereas the inward passage of lipid soluble drugs is restricted by drug efflux pumps which act as a functional barrier. In the present work, a transferrin-coupled liposomal system for brain delivery of 5-florouracil has been investigated.5-florouracil and (99m)Tc-DTPA bearing non-coupled liposomes were prepared by cast film method, which were coupled with the transferrin by incubating these liposomes with transferrin in the presence of the 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride in saline phosphate buffer (pH 7.4). These liposomal systems were characterized for vesicle size, percent drug entrapment, and in vitro drug release. The size of the liposomes was increased on coupling with transferrin while percent drug entrapment reduced. The results of the in vitro release profile demonstrated that non-coupled liposomal formulation releases a comparatively higher percent (i.e. 74.8+/-3.21%) of drug than coupled liposomes. Results of in vivo study suggested a selective uptake of the transferrin-coupled liposomes from the brain capillary endothelial cells. In case of coupled liposomes, the level of radioactivity was 17-fold more as compared to the free radioactive agent and 13 times more with the non-coupled liposomes. Therefore, it could be concluded that using transferrin coupled liposomes the brain uptake of the drug could be enhanced.

Solid lipid nanoparticles bearing flurbiprofen for transdermal delivery.

Topical application of the drugs at the pathological sites offer potential advantages of delivering the drug directly to the site of action and thus producing high tissue concentrations of the drug. The solid lipid nanoparticles (SLN) bearing flurbiprofen were prepared by microemulsion method by dispersing o/w microemulsion in a cold aqueous surfactant medium under mechanical stirring. The SLN gel was prepared by adding SLN dispersion to polyacrylamide gel prepared by using polyacrylamide (0.5%), glycerol (10%), and water (69.5%). Shape and surface morphology was determined by scanning electron microscopy that revealed fairly spherical shape of the formulation. Percent drug entrapment was higher in SLN dispersion in comparison to SLN gel formulations. In vitro drug release, determined using cellophane membrane, showed that SLN dispersion exhibited higher drug release compared with SLN gel formulations. Both the SLN dispersion and SLN-gel formulation possessed a sustained drug release over a 24-hr period, but this sustained effect was more pronounced with SLN-gel formulations. The percent inhibition of edema after 8 hr was 55.51 +/- 0.26% in case of SLN-T4-gel, whereas flurbiprofen and SLN-T4 dispersion exhibited 28.81 +/- 0.46 and 31.89 +/- 0.82 inhibition of edema. The SLN-T4-gel not only decreased the inflammation to larger magnitude, but also sustained its effect.

Design and development of multivesicular liposomal depot delivery system for controlled systemic delivery of acyclovir sodium.

The aim of the present study was to design a depot delivery system of acyclovir sodium using multivesicular liposomes (MVLs) to overcome the limitations of conventional therapies and to investigate its in vivo effectiveness for sustained delivery. MVLs of acyclovir were prepared by the reverse phase evaporation method. The loading efficiency of the MVLs (45%-82%) was found to be 3 to 6 times higher than conventional multilamellar vesicles (MLVs). The in vitro release of acyclovir from MVL formulations was found to be in a sustained manner and only 70% of drug was released in 96 hours, whereas conventional MLVs released 80% of drug in 16 hours. Following intradermal administration to Wistar rats, the MVL formulations showed effective plasma concentration for 48 hours compared with MLVs and free drug solution (12-16 hours). C(max) values of MVL formulations were significantly less (8.6-11.4 microg/mL) than MLV and free drug solution (12.5 microg/mL). The AUC(0-48) of the MVL formulations was 1.5- and 3-fold higher compared with conventional liposomes and free drug solution, respectively. Overall, formulations containing phosphatidyl glycerol as negatively charged lipid showed better results. The MVL delivery system as an intradermal depot offers the advantage of a very high loading and controlled release of acyclovir for an extended period of time. The increase in AUC and decrease in C(max) reflects that the MVL formulations could reduce the toxic complications and limitations of conventional iv and oral therapies.

Colon Targeted Liposomal Systems (CTLS): Theranostic Potential.

Colon targeted liposomal systems (CTLS) for the delivery of bioactives have been well addressed in therapeutic manifestations of colonic ailments. Number of approaches using various drug delivery systems for colon targeting has been worked out but CTLS are first time being lime lighted in this review. Although liposomes are not supposed to be suitable for colon targeting via oral route this review explicitly provides advances of CTLS using exploitable ligands such as peptides or proteins (e.g. RGD, NGR, fibronectin mimetic peptide, and transferrin), Sialyl Lewis X (SLX), low molecular weight ligand like folate, monoclonal antibodies, endostatin gene and sulfatide etc. Moreover, it is bringing forth the diagnostic (or imaging) potential of CTLS using (188)Re, (99)mTc, and (111)In, etc. This review presents nanotechnology based advances for liposome researchers engaged in design and development of colon targeted liposomes for theranostic exploration.

Mercapto functionalized silica entrapped polyacrylamide hydrogel: Arsenic adsorption behaviour from aqueous solution.

In this article, 3-mercaptopropyl functionalized silica entrapped polyacrylamide hydrogel (MPFS-PAA) was prepared and characterized by FT-IR, scanning electron microscopy (SEM) and energy dispersion X-ray spectroscopy (EDS). Synthesized hydrogel was evaluated for removal of arsenic(III) from aqueous solution. Adsorption studies were carried out by batch method as function of contact time, initial concentration of arsenic and pH. As(III) adsorption data fitted well with Langmuir and Freundlich isotherm models. Adsorption capacity of arsenic 92.5 µg/g was obtained at initial concentration of 100 µg/L by Langmuir isotherm. Adsorption kinetics was tested for pseudo-second order reaction at different contact time. The rate constants of pseudo second order reaction were calculated and good correlation coefficient R(2) 99.67 obtained. The results indicates that MPFS-PAA is an effective adsorbent for removal of As(III) from aqueous solution.
