Objective(s): The aim of this study was to explore the effects of Squid ink polysaccharide (SIP) on prevention of autophagy and oxidative stress induced by cyclophosphamide (CP) in Leydig cells of mice. Materials and Methods: Examination of reproductive organ exponents, abnormal sperm rate, activities of superoxide dismutase (SOD), catalase (CAT), contents of malondialdehyde (MDA), and histolog...

In this article we introduce the zero-divisor graphs ?P(X) and ?P? (X) of two rings CP(X) CP? (X); here P is an ideal closed sets in X aggregate those functions C(X), whose support lie on P. analogue ring C?(X). We determine when weakly graph W?P(X) coincides with ?P(X). find out conditions topology X, under-which (respectively, (X)) becomes triangulated/ hypertriangulated. realize that a compl...

In this article, theoretical studies on the selective complexation of the halide ions (F¯, Cl¯ and Br¯) and ion pairs (Na+F¯, Na+Cl¯ and Na+Br¯) with the cyclic nano-hexapeptide (CP) composed of L-proline have been performed in the gas phase. In order to calculate the dispersion interaction energies of the CP and ions, DFT-D3 calculations at the M05-2X-D3/6-31G(d) level was employed. Based on t...

Background Cyclophosphamide (CP) is a chemotherapeuticdrug which causes deleterious effects on tissue of testicle and increases free radicals in the body. The aim of this study is to investigate protective effects of ethyl pyruvate (EP) on improvement of testicle inCP treated animals. MaterialsAndMethods In this study, 15 male mice(6-8 weeks) were divided into 3 groups. Control group receivedno...

In this study, degradation of p-chlorophenol (p-CP) was evaluated using persulfate (PS) activated zerovalent iron (ZVI) based ultraviolet (UV) in a bench scale photoreactor. The effect of operational parameters such as solution pH (3, 7, and 11), reaction time (0-60 minutes), ZVI dosage (0.15, 1.25, 0.5, 1, and 1.5 mM), PS concentration (0.5, 1.5, 2, 2.5, 3, and 4 mM), and initial p-CP concentr...

We construct a closed smooth 4-manifold which is homeomorphic but not diffeomorphic to CP#4C̄P 2 and describe its handlebody picture.
