p28 and nrc peptides are two anticancer peptides with various mechanisms have shown to be effective against breast cancer. therefore, it seems that construction of a chimeric protein containing the two peptides might cause synergistic cytotoxic effects. however, since the two peptides bear opposite charges, production of a chimeric protein in which the two moieties do not intervene each other i...

Objective(s): Breast cancer remains a global challenge, and further chemopreventive therapies are still immediately required. Emerging evidence has revealed the potent anti-cancer effects of biguanides, Metformin (MET) and phenformin (PHE). Thus, to explore an efficient chemopreventive strategy for breast cancer, the antiproliferative effects of the combination of MET and PHE against breast can...

objective: the use of fetal hemoglobin (hbf) inducer drugs is considered as a novel approach in treatment of β-hemoglobinopathies, especially β- thalassemia and sickle cell disease. hbf inducers including hydroxyurea, histone deacetylase (hdac) inhibitor agents such as sodium butyrate, azacitidine, decitabine and new immunomodulator drugs like pomalidomide, lenalidomide and thalidomide can redu...

we studied the antioxidant activities of the essential oils of zataria multiflora boiss. (zeo) and bunium persicum (boiss.) b. fedtsch (beo) in mixed form on linseed oil using (dpph•), ­(­abts•+), h2o2 scavenging, and reducing power assays. after calculation of ic50 for zeo and beo separately, interactions of the essential oils were investigated at the form of mixture and the results were given...

Background: Radon and its short-lived decay products are considered as the important sources of public exposure to natural radioactivity. The synergistic interaction between tobacco smoking and radon is known to be an actual problem. This study has provided a mathematical description and prognosis of the carcinogenic effects after combined action of radon with smoking. Materials and Me...

Metformin and berberine have been reported to have lipid lowering effects. This study aims to investigate lipid lowering effects of berberine and metformin, alone and in combination, in HepG2 cells to determine whether berberine and metformin work synergistically and elucidate their mechanisms. HepG2 cells were treated with 33 mM glucose in the presence of various concentrations of berberine an...

Floral landscapes comprise diverse phytochemical combinations. Individual phytochemicals in floral nectar and pollen can reduce infection in bees and directly inhibit trypanosome parasites. However, gut parasites of generalist pollinators, which consume nectar and pollen from many plant species, are exposed to phytochemical combinations. Interactions between phytochemicals could augment or decr...

Novel synergistic effects between Lewis and Brønsted acids in Prins cyclization are reported. Non-reactive Lewis acids and non-reactive Brønsted acids, which failed to perform Prins cyclization when used alone, have shown remarkable synergistic effects when used in combination to perform the reaction successfully.

Network structure can have a significant impact on the propagation of diseases, memes, and information on social networks. Different types of spreading processes (and other dynamical processes) are affected by network architecture in different ways, and it is important to develop tractable models of spreading processes on networks to explore such issues. In this paper, we incorporate the idea o...

The complex pathology of cancer development requires correspondingly complex treatments. The traditional application of individual single-target drugs fails to sufficiently treat cancer with durable therapeutic effects and tolerable adverse events. Therefore, synergistic combinations of drugs represent a promising way to enhance efficacy, overcome toxicity and optimize safety. Chinese Herbal Me...
