OBJECTIVE To study balance control on a moving platform in lower limb amputees. DESIGN Observational cohort study. PARTICIPANTS Unilateral transfemoral and transtibial amputees and able-bodied control subjects. INTERVENTIONS Balance control on a platform that moved in the anteroposterior direction was tested with eyes open, blindfolded and while performing a dual task. MAIN OUTCOME MEAS...

OBJECTIVES Lung cancer is associated with a significant rate of locoregional recurrence after surgical resection, particularly when nonanatomic wedge resections are performed. The primary aim of this study was to assess the feasibility of a microsphere drug delivery system to locally deliver chemotherapy and prevent the establishment and growth of lung cancer cells and establish proof of concep...

Prostate cancer is the most common cancer in men. In this study, we investigated immune responses of cytotoxic T lymphocytes (CTLs) against TRAMP-C2 prostate cancer cells after activation by dendritic cells (DCs) loaded with TRAMP-C2 freeze-thaw antigen and/or PEP-3 peptide in vitro. Bone marrow-derived DC from the bone marrow of the C57BL/6 were induced to mature by using the cytokine of rhGM-...

BACKGROUND AND THE PURPOSE OF THE STUDY Amphotericin B (AmB) which is an appropriate antibiotic for the treatment of mycosis has many toxic effects including nephrotoxicity. Recently preparation of a new drug loaded nanoparticles for the reduction of toxicity and increase in the effectiveness of AmB has been reported. The objective of this study was to prepare and evaluate in vitro and in vivo ...

Biotin and retinoic acid grafted pullulan conjugate was synthesized using carbodiimide activation ester bond formation strategy for biotin targeted delivery of doxorubicin in breast cancer chemotherapy using micelle formulation. The conjugate structure was evaluated and confirmed by proton nuclear magnetic resonance and Fourier transform infrared spectroscopy. Critical micelle concentration of ...

Background: In vitro culture of ovarian follicles may preserve fertility in women with premature ovarian failure due to cancer .It seems that creation a condition that could maintain cellular communications and supports growth of follicles to produce mature oocytes appear to be essential. Nitric oxide (NO) has been recently shown to act with a dual action in mouse oocyte meiotic maturation depe...

A number of clinical and experimental studies have investigated the effect of simvastatin on bone regeneration. In the present study, the release of simvastatin from simvastatin-loaded calcium sulphate (CS) scaffolds and the effect of these scaffolds on osteogenic differentiation of bone marrow-derived mesenchymal stem cells (MSCs) in vitro and the effect of simvastatin locally applied from CS ...

Multidrug resistance (MDR) in tumor cells is a significant obstacle to the success of chemotherapy in many cancers. The purpose of this research is to test the possibility of docetaxel-loaded poly (e-caprolactone)/Pluronic F68 (PCL/Pluronic F68) nanoparticles to overcome MDR in docetaxel-resistance human breast cancer cell line. Docetaxel-loaded nanoparticles were prepared by modified solvent d...

In this work, indomethacin-loaded poly(l-lactic acid)/poly(lactide-co-glycolide) (IDMC-PLLA/PLGA) microparticles were prepared using solution-enhanced dispersion by supercritical fluids (SEDS) technique in an effort to obtain alternative IDMC formulation for drug delivery system. Surface morphology, particle size and particle size distribution, drug encapsulation efficiency, drug release kineti...

objective(s): sertoli cells support in vivo germ cell production; but, its exact mechanism has not been well understood. the present study was designed to analyze the effect of sertoli cells in differentiation of mouse embryonic stem cells (mescs) to germ cells.   materials and methods: a fusion construct composed of a stra8 gene promoter and the coding region of enhanced green fluorescence pro...
