Abstract
An intermolecular energy transfer system is developed for studying the stability of nanoaggregate(s) (NAs) in complex solution and cell culture by one- and two-photon fluorescence microscopy and optical imaging. The system allows facile addition of one or more tumor targeting molecules, one of which is exemplified here. NAs functionalized with an MRI and optical probe, with and without folic acid, remain stable in fetal bovine serum for at least 4 hours. HeLa cell cultures showed a clear difference between NAs non-targeted and targeted to folate receptors, with both NAs appearing to be taken up by the cells through different mechanisms. An MRI relaxivity, r1, of 9 mM-1 s-1 at 310 K and 1.4 T was measured associated with the increased rotational correlation time of the NAs. These NAs may have application in the targeted drug delivery of hydrophobic drugs such as doxorubicin (DOX).

Abstract
In an experiment with the BigRIPS separator at the RIKEN Nishina Center, we observed two-proton (2p) emission from ^{67}Kr. At the same time, no evidence for 2p emission of ^{59}Ge and ^{63}Se, two other potential candidates for this exotic radioactivity, could be observed. This observation is in line with Q value predictions which pointed to ^{67}Kr as being the best new candidate among the three for two-proton radioactivity. ^{67}Kr is only the fourth 2p ground-state emitter to be observed with a half-life of the order of a few milliseconds. The decay energy was determined to be 1690(17) keV, the 2p emission branching ratio is 37(14)%, and the half-life of ^{67}Kr is 7.4(30) ms.

Abstract
Walking exercise is generally accepted as a valid therapeutic regimen in the treatment of peripheral arterial occlusive disease (PAOD) of Fontaine stage II. In order to quantify the effect of walking exercise and/or drug therapy on regional muscular blood flow, PAOD Fontaine stage II was induced by multiple ligations of the femoral artery and of all side branches in one hindlimb of mongrel dogs; the contralateral extremity served as control. The animals underwent walking exercise with increasing intensities on a tread mill five days per week over one year; one group received 600 mg buflomedil (BF) per day orally in addition. At the end of the training period, the regional blood flow in all skeletal muscles of both hindlimbs was quantified by means of 15 μm radioactively labeled microspheres at resting conditions, after treadmill exercise (ten minutes) with or without preinjection of BF (3 mg/kg body weight) into the abdominal aorta. At resting condition and at the end of treadmill exercise the regional muscular blood flow did not differ significantly between the diseased and control extremity Supplementary oral treatment with BF over one year had no significant effect; the increase in muscular blood flow during treadmill exercise was not enhanced after intra- aortic injection of BE Consequently walking exercise has the potential to increase the functional capacity of collaterals in intermittent claudication and to restore blood supply to skeletal muscle.

Abstract
JMJD2B is a histone demethylase enzyme that regulates gene expression through demethylation of H3K9me3. Although mutations of JMJD2B have been suggested to be responsible for neurodevelopmental disorders, the function of JMJD2B in the central nervous system (CNS) remains to be elucidated. Here we show that JMJD2B has a critical role in the development of the CNS. We observed JMJD2B expression, which was especially strong in the hippocampus, throughout the CNS from embryonic periods through adulthood. We generated neuron-specific JMJD2B-deficient mice using the cre-loxP system. We found an increase in total spine number, but a decrease in mature spines, in the CA1 region of the hippocampus. JMJD2B-deficient mice exhibited hyperactive behavior, sustained hyperactivity in a novel environment, deficits in working memory and spontaneous epileptic-like seizures. Together these observations indicate that JMJD2B mutant mice display symptoms reminiscent of neurodevelopmental disorders. Our findings provide evidence for the involvement of histone demethylation in the formation of functional neural networks during development.

Abstract
The aim of this study was to investigate whether rs41274853 in the 3'-untranslated region of the ciliary neurotrophic factor receptor gene (CNTFR) is associated with elite sprint/power athletic status and assess its functional significance. A total of 211 Japanese sprint/power track and field athletes (62 international, 72 national, and 77 regional athletes) and 814 Japanese controls were genotyped at rs41274853. Luciferase reporter assay was conducted to investigate whether this C-to-T polymorphism affects binding of microRNA miR-675-5p to this region. The TT genotype was significantly more frequent among international sprint/power athletes (19.4%) than in the controls after Bonferroni correction (7.9%, P=0.036, OR=2.81 [95% CI: 1.43-5.55]). Furthermore, in non-athletic young/middle-aged men (n=132), TT genotype carriers exhibited significantly greater leg extension power (26.6±5.4 vs. 24.0±5.4 W/kg BW, P=0.019) and vertical jump performance (50.1±6.9 vs. 47.9±7.5 cm, P=0.047) than the CC+CT genotype carriers. Reporter assays revealed that the miR-675-5p binds to this polymorphic region within the CNTFR mRNA, irrespective of the rs41274853 allele present. Although the functional significance of the rs41274853 polymorphism remains unclear, the CNTFR is one of the candidate genes contributing to sprint/power performance.

Abstract
OBJECTIVE To determine the toxicological effect of ZnO nanoparticles (NPs), inflammatory responses, serum biological parameters and oxidative stress markers of Superoxide dismutase (SOD) were evaluated followed by intravenous treatment of ZnO NPs in mice. MATERIALS AND METHODS Inflammatory responses induced by a dose of 0.2 mg/kg ZnO NPs, followed by a single intravenous treatment were examined in mice. In addition, the serum biological parameters and oxidative stress markers were evaluated. Blood and spleen were collected following treatment. The mRNA transcript levels of inflammatory-related genes (TNF-α and IL1-β) were elevated in the spleen cells of mice treated with ZnO NPs at 12h. RESULTS The elevated levels of TNF-α and IL1-β in supernatants of spleen cell cultures of mice treated with ZnO NPs were also observed at 24h. The serum aspartate aminotransferase, glutamate pyruvate alanine aminotransferase, and lactate dehydrogenase levels significantly increased at 6h and 12h in ZnO NPs treated group, indicating liver cell injury and tissue damage. On the other hand, no elevation was observed in BUN and Cre, biochemical markers of kidney damage. SOD activities were significantly elevated at 24 h and 48 h. CONCLUSIONS This study shows the ZnO induced pro-inflammatory response in vivo, that this response may be related to oxidative stress, and to show hepatic damage at an early stage.

Abstract
Differential cross sections of isoscalar and isovector spin-M1 (0(+)→1(+)) transitions are measured using high-energy-resolution proton inelastic scattering at E(p)=295 MeV on (24)Mg, (28)Si, (32)S, and (36)Ar at 0°-14°. The squared spin-M1 nuclear transition matrix elements are deduced from the measured differential cross sections by applying empirically determined unit cross sections based on the assumption of isospin symmetry. The ratios of the squared nuclear matrix elements accumulated up to E(x)=16 MeV compared to a shell-model prediction are 1.01(9) for isoscalar and 0.61(6) for isovector spin-M1 transitions, respectively. Thus, no quenching is observed for isoscalar spin-M1 transitions, while the matrix elements for isovector spin-M1 transitions are quenched by an amount comparable with the analogous Gamow-Teller transitions on those target nuclei.
