Sodium butyrate as a histone deacetylase inhibitor is known to exhibit anti-cancer effects via the differentiation and apoptosis of various carcinoma cells. However, the mechanism by which sodium butyrate induces apoptosis and the involvement of telomerase activity during apoptosis is not completely understood. To investigate the underlying pathways, sodium butyrate's potential to induce apopto...

Gene transfer using different viral vectors has demonstrated different antitumor effects in suicide gene therapy. In the present study, in order to optimize the efficacy of replication-defective adenoviral and lentiviral vectors for gene therapy, RT-PCR was used to evaluate the expression of Drosophila melanogaster deoxyribonucleoside kinase (Dm-d...

in the present study, the effect of intrauterine infusion of zataria multiflora extract on the clinical endometritis was investigated. vaginal examination, transrectal palpation and ultrasonography were used to inspect the genital tract at 30-40 days in milk and two weeks later the same approach was applied. cows with clinical endometritis were randomly divided into three treatment groups: z. m...

The concept of reducing cell-associated blood-borne viruses (BBVs) by filtration of the vector leukocytes from blood collected for transfusion has led to the development of high efficiency filters. Improved filtration technology demands newer methodology to accurately estimate the residual cells. We have developed an experimental model based on the hemocytometer counts and the polymerase chain ...

The recruitment of immune cells from the periphery to the site of inflammation is an essential step in the innate immune response at any mucosal surface. During infection of the urinary bladder, polymorphonuclear leukocytes (PMN; neutrophils) migrate from the bloodstream and traverse the bladder epithelium. Failure to resolve infection in the absence of a neutrophilic response demonstrates the ...

Dideoxypetrosynol A, a polyacetylene from the marine sponge Petrosia sp., is known to exhibit significant selective cytotoxic activity against several human cancer cell lines. In the present study, we investigated further possible mechanisms by which dideoxypetrosynol A exerts its anti-proliferative action in cultured human leukemia U937 cells. Exposure of U937 cells to dideoxypetrosynol A resu...

BACKGROUND This study aimed to investigate the relationship between miR-506 and proliferation and migration of breast cancer cells. MATERIAL AND METHODS MiR-506 mimics, inhibitor, and negative control (NC) were transfected into MDA-MB-231 breast cancer cells. Cell proliferation, cell counting, colony formation assay, and Transwell assay were applied to evaluate the proliferation and migration...

Platelet-rich fibrin (PRF) clots have been used in regenerative dentistry most often, with the assumption that growth factor levels are concentrated in proportion to the platelet concentration. Platelet counts in PRF are generally determined indirectly by platelet counting in other liquid fractions. This study shows a method for direct estimation of platelet counts in PRF. To validate this meth...

This paper demonstrates a commercial-level field-portable lens-free cell analyzer called the NaviCell (No-stain and Automated Versatile Innovative cell analyzer) capable of automatically analyzing cell count and viability without employing an optical microscope and reagents. Based on the lens-free shadow imaging technique, the NaviCell (162 × 135 × 138 mm³ and 1.02 kg) has the advantage of prov...

Anthocyanins are a class of flavonoids, widely spread throughout the plant kingdom, that exhibit important anti-oxidant and anti-inflammatory actions as well as chemotherapeutic effects. However, little is known concerning the molecular mechanisms by which these activities are exerted. In this study, we investigated the anthocyanins isolated from Vitis coignetiae Pulliat for their potential ant...
