This paper shows a circuit to emulate the operation of a photovoltaic (PV) cell. The values of equation is based on data sheet in the Standard Condition Measurement (SCM), this model allows emulate PV cell, including effects due to variations of irradiance receiver and temperature of cell. The generic model is the same for all types of PV cells, only can used the same equations including variab...
Creating heterogeneous tissue constructs with an even cell distribution and robust mechanical strength remain important challenges to the success of in vivo tissue engineering. To address these issues, we are developing a scaffold sheet tissue engineering strategy consisting of thin (∼200 μm), strong, elastic, and porous crosslinked urethane-doped polyester (CUPE) scaffold sheets that are bonde...
Langerhans cell histiocytosis (LCH) is a rare disease with formation of granulomatous infiltrations consisting of Langerhans cells, histiocytes, lymphocytes and eosinophilic granulocytes. The ethiopathogenesis of the disease has not been fully clarified yet. It can occur as focal or disseminated form - acute or chronic. Oral manifestations may be the first signs. This article reports a case of ...
Human THAP1 is the prototype of a large family of cellular factors sharing an original THAP zinc-finger motif responsible for DNA binding. Human THAP1 regulates endothelial cell proliferation and G1/S cell-cycle progression, through modulation of pRb/E2F cell-cycle target genes including rrm1. Recently, mutations in THAP1 have been found to cause DYT6 primary torsion dystonia, a human neurologi...
Fourier Transformed Infrared Spectroscopy (FTIR) has extensively been used for biological applications. Cisplatin is one the most useful antineoplastic chemotherapy drugs for a variety of different human cancers. One of the clinical problems in its application, which would consequently affect the therapeutic outcome of its application, is the occurrence of resistance to this agent. In this proj...
Heart failure is a life-threatening disorder worldwide and many papers reported about myocardial regeneration through surgical method induced by LVAD, cellular cardiomyoplasty (cell injection), tissue cardiomyoplasty (bioengineered cardiac graft implantation), in situ engineering (scaffold implantation), and LV restrictive devices. Some of these innovated technologies have been introduced to cl...
BACKGROUND The safety and efficacy of myocardial regeneration using embryonic stem cells are limited by the risk of teratoma and the high rate of cell death. METHODS AND RESULTS To address these issues, we developed a composite construct made of a sheet of adipose tissue-derived stroma cells and embryonic stem cell-derived cardiac progenitors. Ten Rhesus monkeys underwent a transient coronary...
Previous studies of human retinal pigment epithelium (RPE) morphology found spatial differences in density: a high density of cells in the macula, decreasing peripherally. Because the RPE sheet is not perfectly regular, we anticipate that there will be differences between conditions and when and where damage is most likely to begin. The purpose of this study is to establish relationships among ...

PURPOSE Molecular mechanisms that initiate epithelial-mesenchymal transition (EMT) involved in ocular fibrotic complications remain elusive. Studies were conducted to examine the role of cell-cell contact in regulating EMT and proliferation of retinal pigment epithelial (RPE) cells. METHODS Porcine RPE cells were isolated as sheets and cultured in vitro on lens capsules. Cell morphology was e...
