tuberous sclerosis complex (tsc) is an autosomal-dominant hereditary disorder. this syndrome is characterized by tumor-like malformations in several organs, as well as the heart. this report summarizes a case of tsc in a premature infant, born at 34 weeks' gestation with ascites. after birth, multiple cardiac mass, subependymal cysts and hypopigmented macules were detected. to our knowledge, th...

objectives: language development is often very slower in hearing impaired children compared with their normal peers. hearing impairment during childhood affects all aspects of speech production and language acquisition. it seems that hearing impaired people suffer from language and speech impairments such as production of complex linguistic structures. the purpose of this study is to determine ...

radiation therapy is considered as one of the main methods in cancer treatment. in this method, determination of exact location and geometric properties of tumor is necessary for treatment planning that leads to increased accuracy and output of treatment and reduction of healthy tissue dose. for this purpose, the aim of the present study has been physiological transmission of gallium as a pharm...

background orientation of the stylohyoid complex (shc) may be important for evaluation of the patient with orofacial pain or dysphagia. objectives our purpose was to assess the length and angulations of shc using cone beam computed tomography (cbct). patients and methods in this study, 3d images provided by cbct of 69 patients (36 females, 33 males, age range 15-77 years) were retrospectively e...

encapsulation of olive oil is an effective method to protect it against environmental deteriorative factors. in this research, olive oil microcapsules were produced by complex coacervation method. the objective was to examine the effect of gelatin and arabic gum as shell materials, lactose as cryprotectant, and different acidification times on microencapsulation efficiency of olive oil. arabic ...

the effect of oleic acid (5 and 10% v/v) and xanthan gum (0.5 and 1% wt) on  partitioning and retention of ethyl acetate and diacetyl from two matrices with a different composition was investigated by applying static head space gas chromatography. two matrices with different composition have been developed: one containing carbohydrates (xanthan gum) and in the second one, called complex matrix,...

purpose: to recognize affective factors in delivering x-ray contrast agents (which have high atomic number) via gallium carrier to liver or lymphatic neoplasm cells.   materials and methods: since uptake of gallium by liver has been reported in numerous researches, it was bonded with a contrast media (metrizoate). x-ray imaging was done to determine geometric features of liver.   results: radio...

epistemologically speaking, second language acquisition research (slar) might be reconsidered from a complex dynamical system view with interconnected aspects in the ecosystem of language acquisition. the present paper attempts to introduce the tenets of complex system theory and its application in slar. it has been suggested that the present dominant traditions in language acquisition research...

a novel algorithm for the fast detection of hubs in chemical networks is presented. thealgorithm identifies a set of nodes in the network as most significant, aimed to be the mosteffective points of distribution for fast, widespread coverage throughout the system. we showthat our hubs have in general greater closeness centrality and betweenness centrality thanvertices with maximal degree, while...

macrocyclic heterobinuclear zn(ii)–cu(ii) complexes with phenol based dicompartmental ligands possessing contiguous hexa- and penta-coordination sites were prepared by a stepwise procedure. the ligands include similar n4o2 and dissimilar n(imine)3o2 and n(amine)3o2 coordination sites sharing two phenolic oxygen atoms. the six-coordination site comprises two pyridyl pendant arms on the amine nit...
