the nano-cry zeolite synthesized and characterized by fourier transfer infrared (ft-ir), x-ray diffraction (xrd),and scanning electron microscopy (sem).the result show that nano catalyst prepared with mainly particles size about 30-80 nm .the xrd show the structure of the zeolite does not collapse. this nano-cry zeolite has been used as new, and nontoxic catalyst for catalyzes of synthesis of 2...

new approach of breast cancer therapy is developed toward combination therapy with agent that have a specific molecular target. our previous study showed that citrus aurantifolia lime peels ethanolic extract (cpe) increased the sensitivity of mcf-7 cells againts doxorubicin. this study aims to observe the mechanism of combination cpe and doxorubicin in cell cycle modulation and apoptosis on mcf...

background: genistein (gen), a naturally occurring flavonoid present in soy bean, has attracted scientific interest for its possible benefits in cancer. objective: the potential immunomodulatory effects of genistein on the immune system and against tc-1 tumor cell line were evaluated in adult female c57bl/6 mice. methods: mice were treated with gen 10 days before to 10 days after the tumor indu...

background: given that validity is the baseline of psychological assessments, there is a need to provide evidence-based data for construct validity of such scales to advance the clinicians for evaluating psychiatric morbidity in psychiatric and psychosomatic setting. methods: this comparative cross-sectional study aimed to investigate the construct validity of the malaysian version of the ghq-2...

background and aim: sinusoidal harmonic acceleration (sha) test is one of the most effective and best-tolerated methods to assess vestibular system function, especially horizontal semicircular canal in children. a prerequisite for using this test in children, is the availability of normative data. despite of the numerous studies related to the sha in adults, few researches have been documented ...

reinforced concrete (rc) slabs exhibit complexities in their structural behavior under load due to the composite nature of the material and the multitude and variety of factors that affect such behavior. current methods for determining the load-deflection behavior of reinforced concrete slabs are limited in scope and are mostly dependable on the results of experimental tests. in this study, an ...

objective(s): the study aimed to investigate the effects of resveratrol on colorectal cancer hct116 cells, including cell viability, apoptosis, and migration, and the partial mechanisms focused on hedgehog/gli-1 signaling pathways. materials and methods: we chose the appropriate time and concentration of recombinant human sonic hedgehog (shh) stimulation by cell viability. the proportion of cel...

the ability to maintain and study human tissues in in-vivo environment has proved to be a valuable tool in breast cancer research for several decades. the most widely tissues have been xenografts established human breast cancer cell lines into athymic nude mice. the aim of this study was to provide a new accurate and affordable method for the establishment of breast cancer xenograftin nude mice...

background: hepatitis c (hcv) is a worldwide problem without an effective vaccine with more than 170 million chronically infected people worldwide. dna vaccines expressing antigenic portions of the virus with adjutants have recently been developed as a novel vaccination technology. objectives: in the present study, a dna vaccine expressing hcv core protein was developed with il12 as a genetic a...

the thiosemicarbazides 3a-c were appeared by reaction of the corresponding substituted hydrazides 1a-c with allylisothiocyanate 2. synthesis of some novel 1,2,4-triazole-thiols 4a-c bearing a pyridyl unit using 1-(x-picolinoyl)-4-allyl-thiosemicarbazides (x = 2,3,4) in an alkaline solution, is reported. also, the s-alkylation of triazole derivatives 5-7a-c is described. the structure of the syn...
