Stability of the Volterra Integrodifferential Equation
In this paper, the Hyers-Ulam stability of the Volterra integrodifferential equation and the Volterra equation on the finite interval [0, T], T > 0, are studied, where the state x(t) take values in a Banach space X
Common fixed point theorems in modular G-metric spaces
The purpose of this paper is to prove the existence of the unique common fixed point theorems of a pair of weakly compatible mappings satisfying -maps in modular G-metric spaces
DRD1-DRD5 Expression Profiles in Arthritis Rheumatoid
Objectives
The cause of rheumatoid arthritis (RA) as a chronic inflammatory autoimmune disease is still unknown. It appears that both genetic and environmental factors play a role in its pathogenesis. Recent studies reveal that in addition to the CNS, immune cells synthesis neurotransmitters so that these catecholamines can regulate immune functions. The aim of this study is to evaluate the dopamine receptor gene expression profiles on peripheral blood mononuclear cells of rheumatoid arthritis patients in comparison with normal individuals.
Material & Methods
In the present study, we investigated dopamine receptor gene expression in PBMCs of 40 RA patients and 40 healthy individuals using Real Time-PCR.The specificities of the obtained Real time PCR products for the respective dopamine receptors fragments were confirmed by sequenced analysis capillary system
Results
We found that DRD1-DRD5 types of dopamine receptors genes expression profiles of rheumatoid arthritis patients differ compared to healthy individuals. Moreover, a significant difference of DR2 and DR4 gene expression was seen in rheumatoid arthritis patients.
Conclusion
This study showed that some types of dopamine receptors genes expression profiles alter in rheumatoid arthritis patients with comparison to healthy individuals Moreover, this alteration possibly could result in dysfunction of dopaminergic system in immune cells and finally lead to rheumatoid arthritis
A new species of the family Mesopsocidae (Insecta: Psocoptera) on ash trees from Iran
در بررسی تنوع گونهای بندپایان درختان زبان گنجشک در شهرستان مشهد و حومه، نمونههایی از شپشهای چوب و کتاب در اسفند سال 1392جمعآوری شد که توسط پروفسور Charles Lienhard از موزه تاریخ طبیعی سوئیس با نام علمی Mesopsocus hiemalis Marikowskii (Psocoptera: Mesopsocidae) شناسایی گردید. این خانواده، جنس و گونه برای اولینبار از ایران گزارش میشود
First report of three species of dark-winged fungus gnats (Diptera: Sciaridae), on Pinus mugo Turra, from Iran
During a survey in 2015, three dark-winged fungus gnat species, Bradysia odoriphaga Yang & Zhang, 1985, Bradysia trivittata Staeger, 1840and Scatopsciara atomariaZetterstedt, 1851 were identified and recorded here from Iran for the first time. The genus Scatopsciara Edwards, 1927 is newly recorded from Iran as well. The identification of specimens were confirmed by Dr Kai Heller (Germany). The sciarid species were collected on the pine trees, Pinus mugo Turra, in the urban green landscapes of the city of Mashhad, Khorasan-e Razavi province, Iran
First report of the aphid, Appendiseta robiniae (Gillette, 1907) (Hemiptera: Aphidoidea), from Iran
During the faunistic survey of aphid species associated with ornamental shrubs in the urban green spaces of Mashhad, the capital city of Khorasan-Razavi province of Iran, in 2015, specimens of the species Appendiseta robiniae (Gillette, 1907) were collected from a colony on Vitex agnus-castus. This aphid species is reported here for the first time from Iran
