Toxoplasma gondii is an opportunistic pathogen in which the reactivation of a latent infection can cause death in congenitally infected fetuses, newborns, and immunocompromised patients. This study aimed to determine the seropositivity of toxoplasmosis infection and the possible association with Interleukin-12 (IL-12) and Interleukin-23 (IL-23) cytokines in breast cancer patients. In this study, 190 women were enrolled. All serum samples were tested for T. gondii immunoglobulins (IgG and IgM) antibodies and (IL-12, IL-23) levels using ELISA technique. The result of this study showed that breast cancer patients recorded the highest percentage of toxoplasmosis infection. There were no positivity rates for anti- Toxopl

When the collisions are repeated in a specific location, the case must be studied and solutions must be found to eliminate these collisions.
A GIS is a kind of super map, computer software that links geographic information (where things are) with descriptive information (what things are like). Unlike a flat paper map, where what you see is what you get, a GIS can have many layers of information underneath its surface.
In this paper GIS is used as a tool to examine, analyze, and suggest solutions for areas where traffic collisions have occurred in

This research is related to the study of the energy gap of some glassy polymers (PC,PS and PMMA), we have studied the effect of gamma–ray and UV light radiation on the energy gap of these polymers and then the effect of dyes (anthracene) on the energy gap for these materials for exposure times (0 to 34 hr). It’s found that the energy gap of pure polymers and doped polymers measurement was changed depending on the gamma and UV dose and the mechanism of interaction between molecules of polymers and dye .It was found that the addition of anthracene to polymers leads to a reduction in the energy gap generally.

With the increments number of population nowadays, one of the most essential problems in rural areas is the number of students in each school which exceed the school capacity. Thus, it is important to increase the number of schools and to determine the suitable location of them. The aim of this study is to determine the most suitable sites for school using Geographic Information System (GIS 10.2) (ModelBildur)in Husseiniya district, Karbala province.

Red pigmented undecylprodigiosin produced by Streptomyces coelicolor (A3)2 is a
promising drug owing to its characteristics of antibacterial, antifungal,
immunosuppressive and anticancer activities. The culture of S. coelicolor in liquid
medium produces mainly the blue pigmented actinorhodin and only low quantities of
undecylprodigiosin. From an industrial point of view, it is necessary to find a strategy to
improve undecylprodigiosin production. The present study provides evidence that
cultivation of S. coelicolor on solid substrate resulted in a reversal in this pattern of
antibiotic production as the production of undecylprodigiosin was significantly increased
and actinorhodin was completely suppressed. Four di

Show MoreLaser ablation of a silver target immersed in distilled water using Nd:YAG laser with a fundamental wavelength of 1064nm was carried out to fabricate silver nanoparticles (Ag NPs) with different laser energy in the presence and absence of magnetic field. UV-Visible spectrum showed that the nanoparticles are almost spherical in shape. The number of Ag NPs increased by increasing laser energy while their particle size was reduced by increasing laser energy without magnetic field. In the presence of magnetic field, the size of Ag NPs increased slightly by increasing laser energy. According to AFM results, the presence of magnetic field did not affect the average diameter of Ag NPs. The presence of a magn

Show MoreOptic Disc (OD) localization is a basic step for the screening, identification and appreciation of the risk of diverse ophthalmic pathologies such as glaucoma and diabetic retinopathy.In fact, the fundamental step towards an exact OD segmentation process is the success of OD localization. This paper proposes a fully automatic procedure for OD localization based on two of the OD most relevant features of high-intensity value and vasculature convergence. Merging ofthese two features renders the proposed method capable of localizing the OD within the variously complicated environments such as the faint disc boundary, unbalanced shading, and the existence of retinal pathologies like cotton wall and exudates,which usually share the same

DBScan as a high-quality algorithm has been introduced for clustering spatial data due to its ability to remove noise (outlier) and constructing arbitrarily shapes. However, it has a problem in determining a suitable value of Eps parameter. This paper proposes a new clustering method, termed as DBScanBAT, that it optimizes DBScan algorithm by BAT algorithm. The proposed method automatically sets the DBScan parameters (Eps) and finds the optimal value for it. The results of the proposed DBScanBAT automatically generates near original number of clusters better than DBScanPSO and original DBScan. Furthermore, the proposed method

One of the main problems with Leishmania infections is the capability of these parasites to evade and subvert immune responses of the host. Leishmaniasis is treated with a small arsenal of drugs; all of them have disadvantages in terms of efficacy, high price, toxicity or treatment regimen. In this study, the effect of Zinc oxide nanoparticles (ZnO NPs) was evaluated against intracellular amastigotes Leishmania donovani in vitro conditions. The effect of different concentrations from ZnO NPs (0.18, 0.37, 0.75 and 1.5 μg / ml) was used to study on the viability of amastigotes and macrophages “following infection" using the colori

The contribution of this paper is to overcome some of these weaknesses by proposing a new version of KSA coined as modified KSA . In the initial state of the array is suggested to contain random values instead of the identity permutation. Moreover, the permutation of the array is modified to depend on the key value itself. The proposed performance is assessed in terms of cipher secrecy, randomness test and time under a set of experiments with variable key size and different plaintext size. The results show that the RC4 with improves the randomness and secrecy with
