five treatments including conway medium, media containing 0.1, 0.17, 0.3 and 0.5 mg l-1 ferrous (fe; in the first experiment), media with 1, 1.26, 1.59, 2 mg l-1 concentrations of phosphorous (p; in the second experiment) and a pure sample of tetraselmis suecica were cultured under laboratory conditions. growth rate of the algae was determined using the optical density method at 750 nm and numb...

a:4:{s:10:"Background";s:563:"Type II diabetes is a metabolic disorder that can gradually cause damage to the function of many organs such as the gonads. It is believed that poor blood glucose control is the main cause of diabetic side effects. Avocado (Persea americana) is a native tree of Central and South America that has traditionally been used due to its antioxidant, antiinflammatory, anti...

BACKGROUND T cell immunoglobulin domain and mucin domain-containing molecule 3 (TIM-3), which is preferentially expressed on Th1 cells rather than Th2 cells, is considered to be a negative regulator of Th1 cell function. This suggests that TIM-3 indirectly enhances Th2-type immune responses by suppressing Th1 cell function. METHODS To investigate TIM-3's possible involvement in Th2-type acute...

Since melatonin, the major hormone of the pineal gland, has been shown to inhibit the growth of mammary tumors in animal models of human breast cancer, we examined the hypothesis that this indoleamine has the potential to inhibit breast cancer growth by directly inhibiting cell proliferation as exemplified by the growth of the estrogen-responsive human breast cancer cell line MCF-7 in culture. ...

PURPOSE Nanotechnology is an emerging field with significant translational potential in medicine. In this study, we applied gold nanoparticles (GNP) to enhance radiation sensitivity and growth inhibition in radiation-resistant human prostate cancer cells. METHODS Gold nanoparticles (GNPs) were synthesized using HAuCl4 as the gold particle source and NaBH4 as the reductant. Either thio-glucose...

OBJECTIVES A protocol was designed to produce albumin-coated microbubbles (MBs) loaded with functionalized polylactide (PLA) nanoparticles (NPs) for future drug delivery studies. METHODS Microbubbles resulted from the sonication of 5% bovine serum albumin and 15% dextrose solution. Functionalized NPs were produced by mixing fluorescent PLA and PLA-polyethylene glycol-carboxylate conjugates. N...

Quantum dots (QDs) are a type of fluorescent label with applications in biological molecules, cells and in vivo imaging. The current study investigated the effect of QDs on the toxicity, proliferation, migration and invasion of the EJ human bladder cancer cell line in vitro. The cell counting kit‑8 test was used to measure the survival rate of EJ cells following incubation with varying concentr...

Plasmodium vivax presents a great challenge to malaria control because of the ability of its dormant form in the liver, the hypnozoite, to cause relapse in otherwise fully recovered patient. Research efforts to better understand P. vivax hypnozoite biology have been hampered by the limited availability of its sporozoite form responsible for liver infection. Thus, the ability to cryopreserve and...

Ikan nila memiliki kerentanan terhadap infeksi Aeromonas hydrophila dan itu merupakan kendala pada produksi pengembangan industri akuakultur. yang terinfeksi mengalami perubahan gambaran sel darah disebabkan oleh respon imun ikan. Tujuan penelitian ini untuk mengetahui pengaruh bakteri A. parameter ikan dalam hal total eritrosit (TEC), leukosit (TLC), diferensial leukosit, tanda-tanda klinisnya...

BACKGROUND Stem cell factor (SCF) can stimulate hematopoietic stem cell (HSC) expansion; however, the specific structural region(s) of SCF protein that are critical for this function are still unknown. A novel monoclonal antibody (named 23C8) against recombinant human SCF (rhSCF) was previously found to inhibit the ability of rhSCF to enhance HSC expansion, making it possible to identify the re...
