        Mobarakeh, Zahra Sheikhi,Mirzaei, Khadijeh,Hatmi, Nadia,Ebrahimi, Mandana,Dabiran, Sohaila,Sotoudeh, Gity Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.21

        Background: The aim of this study was to investigate demographic features, dietary habits, and some possible risk factors for being susceptible to breast cancer in Iranian women. Materials and Methods: A study of dietary habits and breast cancer was conducted among 53 Iranian women with histological confirmed disease and 40 matched controls. A dietary habits questionnaire was used to evaluate the pattern of selected food intakes. The risk of cancer was analyzed after adjustment for confounding factors. Age, weight, body mass index (BMI), waist circumference, educational status, parity, lactation, marital status, menopause, history of estrogen therapy, and family history of breast disease or cancer were assessed among participants. Special attention was given to the relationship between consumption of high fat meat, milk, yogurt and cheese as well use of frying oils for frying foods, use of olive/liquid oils for cooking, removing fat from meat and poultry, removing chicken skin and not use of mayonnaise as salad dressing and the risk of breast cancer. Moreover, salad, vegetable and fruit consumption, and eating outdoors owere investigated. Results: Our results revealed significant lower education and higher BMI and waist circumference levels in patients with breast cancer. There was significantly increased breast cancer risk in overweight women in comparison with normal weight (OR=2.91, 95%CI 1.24 to 6.82). High intake of fat dairy products including milk and cheese was found to be a statistically significant factor for increasing breast cancer risk in models adjusting for age, BMI and education. Use of olive/liquid oils for cooking and avoidance of mayonnaise as salad dressing are related to lower risk of breast cancer. The frequency of vegetable and fruit consumption was significantly lower in patients with breast cancer compared to healthy women. Conclusions: Dietary habits might be risk factors for breast cancer among Iranian women. Adoption of a prudent diet could be an appropriate strategy for preventing breast cancer.

        Application of supported TiO2 onto Iranian clinoptilolite nanoparticles in the photodegradation of mixture of aniline and 2, 4-dinitroaniline aqueous solution

        Hamidreza Zabihi-Mobarakeh,Alireza Nezamzadeh-Ejhieh 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.26 No.-

        Clinoptilolite nanoparticles (NCP) were used to increase the photocatalytic activity of TiO2 in the photodegradation of mixture of aniline (AN) and 2, 4-dinitroaniline (DNAN) aqueous solution. The photocatalyst was prepared via calcinations process followed by the ion exchanging of NCP in 0.1 M of ammonium titanyl oxalate monohydrate. Samples were characterized by FT-IR, XRD, DRS and SEM. The degradation extent of the pollutants was calculated by changes in the UV–vis absorbencies of the pollutants at lmax 280 nm for AN and 360 nm for DNAN. The optimal conditions were as: 10 ppm with respect to each pollutant, pH 5.8, catalyst dose of 0.1 g L1 and contact time of 6 h.

        Fabrication and Characterization of a Novel Wound Dressing with Clindamycin Loaded PVA Nanoparticles for Acne Treatment

        Mansoor Mandegari,Laleh Ghasemi-Mobarakeh,Jaleh Varshosaz 한국섬유공학회 2022 Fibers and polymers Vol.23 No.12

        Acne vulgaris is the most common skin disorder that may cause constant scarring on the face. Conventionalmethods for acne treatment have various side effects such as inflammation, dryness, peeling, cutaneous irritation and scalingof the skin. The novel wound dressing coated with nanoparticles containing drug was fabricated as a drug delivery system foracne treatment. In this present, Polyvinyl alcohol (PVA) nanoparticles containing clindamycin were successfully prepared bythe electrospraying method and coated on the surface of cotton fabric. The final drug loaded nanoparticles were characterizedusing Field-emission scanning electron microscope (FE-SEM), Fourier transform infrared (FTIR), X-ray diffraction (XRD),Differential scanning calorimeter (DSC) and biodegradation. The increasing clindamycin concentration in electrosprayingsolution led to reverse effects on the viscosity, electrical conductivity and affect on the diameter of nanoparticles. At variousconcentrations of clindamycin, spherical nanoparticles with uniform size were formed from PVA solution. Also, drug releaserate was investigated using both in vitro dissolution and permeation methods during 720 min. Fractional release curvesobtained exhibited short term release of clindamycin within first 60 min and slower release rate until 720 min. The releaserate of clindamycin was higher from PVA nanoparticles containing 10 % W/W drug than those loaded with 5 % W/W drug. Release plots were analyzed based on Korsmeyer-Peppas model, suggesting Fickian diffusion as the dominant clindamycinrelease mechanism from the PVA nanoparticles. Moreover, the drug release profile of PVA nanoparticles coated cotton fabricwas found to be lower than that for the drug loaded nanoparticles. This study suggests wound dressing coated with PVAnanoparticles as a novel drug delivery vehicle for short term administration of clindamycin for treatment of acne scars.

        Samira Sanjabi,Jaber Keyvan Rad,Hamid Salehi-Mobarakeh,Ali Reza Mahdavian 한국공업화학회 2023 Journal of Industrial and Engineering Chemistry Vol.119 No.-

        The fabrication of multi-level anti-counterfeiting inks with fast and enhanced reversibility and reasonablephotofatigue resistance is a challenging issue nowadays. Smart capsules with nanometric size willfacilitate their stimulation with enhanced responsivity and optical features. Herein, thermo- andphoto-switchable dual-chromic nanocapsules were prepared through miniemulsion polymerization ofmethyl methacrylate together with simultaneous encapsulation of the synthesized leuco-dye derivative(STC) and hydroxyl-functionalized spiropyran (SPOH) with bisphenol A and 1-tetradecanol (TDH) or 1-dodecanol (DDH). The obtained capsules containing TDH (TPL@T) and DDH (TPL@D) showed sphericalmorphology with nanometric size in the range of 90–120 nm. Enthalpy and gravimetry analyses revealedmore than 88 % (for the solvent) and 91 % (for total core materials) have been embedded into thenanocapsules, respectively. Simultaneous encapsulation of SPOH beside STC moieties induced a synergisticeffect on thermochromic efficiency with 1.8-to-2.3-fold enhancement. Moreover, multiple responsivitieswere observed by UV–visible illumination with subsequent color change from colorless to purpleand purple to yellow according to reflectance peak displacements. This makes them suitable for producinginks with multi-level data safety and anticounterfeiting. The coated TPL@D and TPL@T nanocapsuleson cellulose substrate showed thermo-switchable color changes between deep red and colorless, introducingappropriate candidates for portable temperature indicators. Reversible thermo- and photoresponsivityof the printed pattern over 10 heating–cooling and UV–vis cycles exhibited their potentialityin anticounterfeiting multi-level data encryption.

        Novel Average Value Model for Faulty Three-Phase Diode Rectifier Bridges

        Mehdi Rahnama,Abolfazl Vahedi,Arta Mohammad Alikhani,Babak Nahid-Mobarakeh,Noureddine Takorabet 전력전자학회 2019 JOURNAL OF POWER ELECTRONICS Vol.19 No.1

        Rectifiers are widely used in industrial applications. Although detailed models of rectifiers are usually used to evaluate theirperformance, they are complex and time-consuming. Therefore, the Average Value Model (AVM) has been introduced to meetthe demand for a simple and accurate model. This type of rectifier modeling can be used to simplify the simulations of largesystems. The AVM of diode rectifiers has been an area of interest for many electrical engineers. However, healthy dioderectifiers are only considered for average value modeling. By contrast, faults occur frequently on diodes, which eventually causethe diodes to open-circuit. Therefore, it is essential to model bridge rectifiers under this faulty condition. Indeed, conventionalAVMs are not appropriate or accurate for faulty rectifiers. In addition, they are significantly different in modeling. In this paper,a novel application of the parametric average value of a three-phase line-commutated rectifier is proposed in which one diode ofthe rectifier is considered open-circuited. In order to evaluate the proposed AVM, it is compared with experimental andsimulation results for the application of a brushless synchronous generator field. The results clearly demonstrate the accuracy ofthe proposed model.

        A Scientometric Analysis of 20 Years of Research on Breast Reconstruction Surgery: A Guide for Research Design and Journal Selection

        Moghimi, Mehrdad,Fathi, Mehdi,Marashi, Ali,Kamani, Freshteh,Habibi, Gholamreza,Hirbod-Mobarakeh, Armin,Ghaemi, Marjan,Hosseinian-Sarajehlou, Mahdi Korean Society of Plastic and Reconstructive Surge 2013 Archives of Plastic Surgery Vol.40 No.2

        Background Breast reconstruction refers to the rebuilding of a woman's breast using autologous tissue or prosthetic material to form a natural-looking breast. It is increasingly offered to women undergoing mastectomy for breast cancer. However, there is no systematic analysis available for the expanding area of research on breast reconstruction. Methods A bibliometric method was used to obtain a view of the scientific production about breast reconstruction by data extracted from the Institute for Scientific Information (ISI). Specific parameters were retrieved from the ISI. Articles about breast reconstruction were analyzed to obtain a view of the topic's structure, history, and document relationships using HistCite software. Trends in the most influential publications and authors were analyzed. Results The number of articles was constantly increasing. Most highly cited articles described the methods of flap construction in the surgery. Other highly cited articles discussed the psychological or emotional aspects of breast reconstruction, skin sparing mastectomy, and breast reconstruction in the irradiated breast. Conclusions This was the first breast reconstruction scientometric analysis, representing the characteristics of papers and the trends of scientific production. A constant increase in the number of breast reconstruction papers and also the increasing number of citations shows that there is an increasing interest in this area of medical science. It seems that most of the research in this field is focused on the technical aspects of surgery.
