Mesenchymal stem cells (MSCs) have been shown to improve cardiac electrophysiology when administered in the setting of acute myocardial infarction. However, the electrophysiological phenotype of MSCs in situ is not clear. We hypothesize that MSCs delivered intramyocardially to cryoinjured myocardium can engraft, but will not actively generate, action potentials. Cryoinjury-induced scar was crea...

The role of inflammation in colorectal carcinogenesis may differ according to individuals' genetic variations. Therefore, we investigated whether genetic susceptibility alters the association between inflammatory potential of diet and the risk of colorectal cancer within the Korean population. We genotyped four polymorphisms in four genes (IL1B, TNF, PPARG, and PPARGC1A) and calculated the diet...

Corticospinal tract (CST) neurons are dislocated in the motor cortex of Reelin-deficient mouse, reeler. In the present study, we examined whether postnatal axonal growth arising from these dislocated CST neurons are normal or not with use of anterograde tracer, DiI and retrograde tracer, HRP. A single injection of DiI into the motor cortex of the normal and reeler mice was made during postnatal...

We present in this report two modelizations of vibrational relaxation processes in a gaz: the Landau-Teller (LT) model and the master equations (ME). We give diierent models for VT and VV rate constants. We propose an algorithm to solve the equations of vibrational relaxation (LT or ME) coupled with conservation equations of momentum and total energy. Both models are compared on the computation...

OBJECTIVES To examine the effect of free radicals from peroxidized oil and the role of albumin on the passage of radicals. DESIGN Prospective study. SETTING Clinical IVF laboratory and university department. PATIENT(S) Blood samples were donated by laboratory staff. INTERVENTION(S) Examination of the effects of mineral oil samples with various peroxide value (POV) on culture of erythroc...

Human corneal endothelial cells (HCECs) do not replicate after wounding. Therefore, corneal endothelial deficiency can result in irreversible corneal edema. Descemet stripping automated endothelial keratoplasty (DSAEK) allows selective replacement of the diseased corneal endothelium. However, DSAEK requires a donor cornea and the worldwide shortage of corneas limits its application. This review...

Outbreak of a new coronavirus infection (COVID-19) has spread rapidly around the world, causing enormous economic and social hardship. Severe acute respiratory syndrome caused by SARS-CoV-2 (Severe Acute Respiratory Syndrome CoronaVirus 2), millions cases death all over world. The relevance this problem is supported continuing risk outbreaks disease, emergence strains virus, as well presence lo...
