Solutions of systems of variational inequalities on fixed points of nonexpansive mappings
Hossein Piri 대한수학회 2014 대한수학회보 Vol.51 No.3
In this paper, we introduce a new approximating method for finding the common element of the set of fixed points of nonexpansive mappings and the set of solution of system variational inequalities for finite family of inverse strongly monotone mappings and strictly pseudo-contractive of Browder-Petryshyn type mappings. We show that the sequence converges strongly to a common element the above two sets under some parameter controling conditions. Our results improve and extend the results announced by many others.

Coefficient Bounds for Several Subclasses of Analytic and Biunivalent Functions
Rahrovi, Samira,Piri, Hossein,Sokol, Janusz Department of Mathematics 2019 Kyungpook mathematical journal Vol.59 No.2
In the present paper, some generalizations of analytic functions have been considered and the bounds of the coefficients of these classes of bi-univalent functions have been investigated.

Background: Dermatoscopy can be applied to diagnose pigmented skin lesions. The aim of the present study was to compare dermatoscopic and histopathologic results in basal cell carcinoma (BCC) and melanocytic nevus of theface. Materials and Methods: In an analytical-descriptive study, 61 patients suspected of BCC or melanocytic nevi of face were randomly selected. The skin lesions of patients were evaluated with dermatoscopic method from February 2012 to February 2014 and results were compared with pathological features of samples. Results: In this study, mean age of patients was $49.5{\pm}18.9$. Some 25 (41%) were men and 36 (59%) were women. In 27 cases (44.3%) there was diagnosis of melanocytic nevus, in 28 cases (45.9%) diagnosis of BCC, and in 3 cases (4.9%) there was mixed diagnosis. The relationship between patients' gender and dermatoscopic diagnosis of the patients was statistically significant (P=0.001). For BCC the sensitivity and specificity of dermatoscopic method were 100% and 97% respectively and for melanocytic nevi 96.4% and 97%. Conclusions: Dermatoscopic study not only can be helpful in improving clinical diagnosis while guiding missed malignant lesions to pathologic evaluations, but also could be useful in evaluating further suspicious or recurrent cases.

Infertility is one of the disorders that worries many couples around the world, although novel and molecular methods can be used to cure this disease in different stages. One of the factors that causes infertility in men and women is the increased oxidative stress within the cells, which can lead to damage in zygote formation. ROMO1 is one of the most important proteins in the production of reactive oxygen species. This protein can enhance oxidative stress in the cells and body through cellular pathways, such as TNF-a and NF-kB routes, which will eventually lead to many diseases, especially infertility. We engage several international databases by using keywords; ROMO1, Infertility, and Reactive Oxygen Species, and gained a great quantity of information about ROMO1, Infertility, and Oxidative Stress. Although not proven, it is hypothesized that ROMO1 might elevate oxidative stress by activating NF-kB pathway in the cells, furthermore, TNF-a can arouse ROMO1 that can end up with apoptosis and cell death, which consequently can have a lot of disturbing effects on the body, especially the reproductive system. To sum up, revealing the exact cellular and molecular mechanisms of ROMO1-dependent TNF-a and NF-kB pathways in the pathogenesis of infertility might find interesting therapeutic and management strategies for this disorder.
