mucosal surfaces of the body provide a universal entry portal for all known and emerging infectious pathogenic microbes. therefore, it seems that special vaccination strategies are needed for vaccines that can hinder the entry capability of pathogenic microbes through the mucosal surfaces. lactic acid bacteria are widely used in the food industry and are presently applied as delivery vehicles i...

objectives : this study sought to assess the effect of low-level laser (lll) on pain and trismus after impacted mandibular third molar surgery. materials and methods : this double blind controlled clinical trial was conducted on 40 healthy patients with no underlying disease and impacted mesioangular mandibular third molars with the same level of difficulty. the patients were divided into two g...

in addition to graft clarity, an acceptable refractive error is essential to consider a corneal transplant successful. the most common complication of penetrating keratoplasty (pk) is postkeratoplasty astigmatism which can result in decreased visual acuity, anisometropia, and mono-ocular diplopia. these complications can cause patient dissatisfaction, in spite of a successful transplant. intrao...

in this paper, we present a new brain tissue segmentation method based on a hybrid hierarchical approach that combines a brain atlas as a priori information and a least-square support vector machine (ls-svm). the method consists of three steps. in the first two steps, the skull is removed and cerebrospinal fluid (csf) is extracted. these two steps are performed using the fast toolbox (fmrib's a...

In this work, we propose a simple method for obtaining the algebraic solution of a complex interval linear system where coefficient matrix is a complex matrix and the right-hand-side vector is a complex interval vector. We first use a complex interval version of the Doolittle decomposition method and then we restrict the Doolittle's solution, by complex limiting factors, to achieve a complex in...

in this paper, vector ultrametric spaces are introduced and a fixed point theorem is given forcorrespondences. our main result generalizes a known theorem in ordinary ultrametric spaces.

there are more than 350 million individuals with hepatitis c in the world. one of the important problems in vaccine project is development of effective and suitable adjuvant in human vaccines. at present research we applied human βhsp90 protein as an adjuvant in recombinant hcv vaccine design. the thermal vector of pgp1-2 was used for human heat shock protein 90 expression. this protein injecte...

background : mosquitoes are considered as the vectors of dirofilariasis and some vector borne disease in iran. the objective of this study was to determine the susceptibility level of the vectors to various insecticides recommended by who for any control measures in an endemic area in northwestern iran. methods : mosquito larval and adult collections were carried out using different methods pro...

background: cutaneous leishmaniasis is a major health problem in iran in spite of implementation of control pro­gram. this infectious disease caused morbidity in less than 27000 people in 2010. this study was set to determine some ecological aspects of sand flies in fasa district, fars province, southern iran during 2011–2012. methods: a total of 4792 sand flies were captured by means of sticky...

Background: The micro-ribonucleic acids (miRNAs) are noncoding RNA molecules that are conserved developmentally and include usually 18-25 nucleotides. MiRNA regulates gene expression through mRNA degradation or inhibiting of its translation. These biomolecules contribute in cellular physiologic and pathologic processes and most of them may act as oncogenes or tumor inhibitors. Identification of...
