Abstract

The 2011 nuclear disaster in Fukushima was not only a health disaster, but also an information disaster. Although media can promote health communication following disasters, studies have revealed associations between media information and negative psychological reactions. To clarify the relationship between media utilization and current health anxiety due to radiation exposure, a cross-sectional questionnaire survey was conducted in Fukushima. We selected 2000 subjects from evacuation (i.e., 500) and non-evacuation (i.e., 1500) areas by two-stage stratified random sampling. As the independent variable, participants were asked about current health anxiety due to radiation exposure at the time of answering the questionnaire. For utilization of media about radiation exposure, local media, national media, Internet media, public broadcasts, and public relations information from local government were set as the dependent variables. Questionnaire data were analyzed by evacuation type (i.e., forced/voluntary). In a multivariate logistic regression analysis, the use of public relations information was significantly associated with lower anxiety for the forced evacuees (odds ratio: 0.72; 95% confidence interval: 0.56–0.93). Our findings highlight the importance of public relations information from local government in terms of it being associated with lower current health anxiety, and this could potentially aid in preparing for future disasters.

22. MAP4 is the in vivo substrate for CDC2 kinase in HeLa cells: identification of an M-phase specific and a cell cycle-independent phosphorylation site in MAP4

Abstract

The microtubule-stabilizing ability of a major HeLa cell microtubule-associated protein (MAP4) was previously observed to be decreased by cdc2 kinase. It was found that cdc2 kinase is the major M-phase MAP4 kinase and two phosphorylation sites within the proline-rich domain of MAP4 were determined. Metabolic 32P labeling revealed increased phosphorylation of MAP4 at mitosis. A specific inhibitor of cdc2 kinase, butyrolactone I, impeded phosphorylation of MAP4 both in mitotic HeLa cells and in the mitotic HeLa cell extract.

Abstract

Protein-deprived male Wistar rats were analyzed after infusion of hypertonic sodium and urea to determine the effects of protein deprivation on renal medullary organic osmolyte content and urea concentration. Protein-deprived Wistar rats exhibited low levels of sodium-dependent myo-inositol transporter (SMIT) messenger ribonucleic acid expression (mRNA). Infusion of NaCl and urea in the renal medulla did not alter the levels of SMIT mRNA in protein-deprived rats due to reduced levels of myo-inositol.

28. Organic osmolytes in rat renal inner medulla are modulated by vasopressin V(1) and/or V(2) antagonists

Abstract

Analysis of the influence of oral administration of vasopressin V1 and /or V2 antagonists on organic osmolytes in rat renal inner medulla shows that these antagonists change the accumulation of a few osmolytes. Different organic osmolytes exhibit different responses to the V1 or V2 receptor antagonists. V2 receptor suppresses taurine accumulation while V1 receptor increases the accumulation of betaine.

29. Impairment of renal medullary osmolyte accumulation in potassium-depleted rats

Abstract

Experimental analysis of the influence of potassium depletion on osmolytes in the renal medulla of rats shows that potassium depletion leads to defects in the renal concentration, which are different for polyuria and polydipsia, and decreased accumulation of osmolytes. High sodium extracellular osmolality inhibits the accumulation of betaine, sorbitol and taurine in inner medulla.
