Abstract

Marine medaka Oryzias melastigma at 4 months (young), 8 months (middle-aged) and 12 months old (senior) were employed to determine age-associated change of sex ratios, sex hormones, telomere length (TL), telomerase activity (TA), telomerase transcription ( omTERT ) and oxidative damage in the liver. Overall, O. melastigma exhibited gradual senescence, sex differences in longevity (F > M), TL (F > M) and oxidative damage (F < M) during aging. In females, the plasma E2 level was positively correlated with TL (TRF > 5 kb), TA and omTERT expression ( p ≤ 0.01), and negatively correlated with liver DNA oxidation ( p ≤ 0.05). The results suggest high levels of E2 in female O. melastigma may retard TL shortening by enhancing TA via TERT transcription and/or reducing oxidative DNA damage. The findings support TL shortening as a biomarker of aging and further development of accelerated TL shortening, abnormal suppression of TA and excessive oxidative DNA damage as early molecular endpoints, indicative of advanced/premature aging in marine medaka/fish.

Abstract

Abstract: We investigated molecular states and cluster gas-like states in light nuclei based on theoretical calculations with antisymmetrized molecular dynamics. The calculated results of 13B suggest that largely deformed states construct rotational bands, and , starting from 5 MeV and 8 MeV, respectively. The neutron structure of the is analogous to the intruder ground state of 12Be. In the predicted band, we found largely deformed structure with a proton excited configuration. The band-head state is assigned to the (4.83 MeV), which was experimentally suggested to be the proton intruder state. Structure of 8He were also investigated. In the results, it was found that the ground state of 8He has both the j-j coupling feature ( closure) and the L-S coupling feature (4He). The results also suggest possible existence of the state with dineutron gas-like structure of 4He, which has an analogy to the 3α-cluster structure of the 12C() state. [Copyright &y& Elsevier]

Abstract

We have studied the coexistence of cluster structure and mean-field-type structure in 40Ca using Antisymmetrized Molecular Dynamics (AMD) + Generator Coordinate Method (GCM). By energy variation with constraint, we calculated GCM basis wave functions. Superposing cluster structure wave functions and mean-field-type structure wave function, we found that α-36Ar and 12C-28Si cluster structure are important components of normal-deformed (ND) band of 40Ca and that of superdeformed (SD) band of 40Ca, respectively.

50. Estimation of coronary flow reserve with the use of dynamic planar and SPECT images of Tc-99m tetrofosmin.

Abstract

Background: We developed a noninvasive method to examine coronary flow reserve with technetium 99m tetrofosmin based on the microsphere model. According to the microsphere model, myocardial blood flow (MBF) can be calculated by MBF = q / integral C(t)dt, where q is myocardial activity and C(t) is tracer concentration in blood. Because the ratio of integral C(t)dt at stress to rest is equal to the ratio of the first transit count in the pulmonary artery (PA) and attenuation factors were canceled out, we calculated the increase ratio of MBF (MBF(IR)).Methods and Results: After injection of dipyridamole, tetrofosmin was injected as a bolus and serial dynamic planar images were obtained to measure the first transit count in PA (PAC). Myocardial single photon emission computed tomography was performed to measure the regional myocardial count (RMC). MBF(IR) was calculated as [(RMCs x PACr)/(RMCr x PACs) - 1] x 100, where r and s denote resting and stress conditions, respectively. In contrast, the increase in the myocardial uptake ratio (MUR(IR)) was defined as (RMCs x SCr/RMCr x SCs - 1) x 100, where SC is syringe count of tracer. The results were as follows: (1) The mean MBF of healthy subjects was 46.9% +/- 22.8%. (2) MBF(IR) of the infarcted region and ischemic region was significantly decreased (8.3% +/- 12.2% and 11.2% +/- 11.9%, respectively; P <.001). (3) MUR(IR) was significantly lower than MBF(IR) (14.1% +/- 21.2%; P <.001). (4) MBF(IR) decreased according to the heart rate at rest (r = 0.47; P <.05).Conclusions: MBF(IR) is a potential parameter with which to evaluate coronary flow reserve when the changes of arterial input function during stress are considered.
