Building upon Beaudry and Koop’s (1993) analysis, we consider a “current depth of the recession” (CDR) variable in modeling the time-series behavior of the postwar quarterly U.S. unemployment rate. The CDR approach is consistent with the state-dependent behavior in the unemployment rate documented in the business-cycle asymmetry literature. We show that while the CDR effect is significant in-sa...

Mature Megalobatrachus oocytes contain 43 fig DNA per oocyte, as compared with 250 pg DNA in a hepatocyte of the same animal. Megalobatrachus oocytes respond to CdR treatment by an increased incorporation of PH]lysine into basic proteins associated with ooplasmic particles, with an optimal CdR concentration at 2 mM. The nucleolus is the most active site of [H]lysine incorporation. It is suggest...

Carcinoid tumors are rare neuroendocrine tumors (NETs) that are increasing in incidence. Mutation and altered expression of Wnt/β-catenin signaling components have been described in many tumors but have not been well-studied in NETs. Here, we observed accumulation of β-catenin in the cytoplasm and/or nucleus in 25% of clinical NET tissues. By mutational analysis, the mutations of β-catenin (I35...

Aberrant epigenetic changes are known to contribute to various phases of tumor development. The gene function loss caused by aberrant methylation is analogous to genetic mutations. Unlike genetic mutations, epigenetic alterations can be reversed. 5-Aza-2'-deoxycytidine (5-aza-CdR) has been approved by the Food and Drug Administration for the treatment of certain types of cancer, such as MDS and...

PURPOSE To assess the relationships between optic cup-to-disc ratio (CDR) and age, sex, and other demographic and health characteristics in the healthy Korean population. METHODS The study design was retrospective and population-based. A total of 28,377 subjects who participated in the Korea National Health and Nutrition Examination Survey between 2008 and 2011 were enrolled in this study. Pa...

The tumor suppressor, p53, negatively regulates cell migration and invasion in addition to its role in apoptosis, cell cycle regulation and senescence. Here, we study the roles of p53 in PDGF-induced circular dorsal ruffle (CDR) formation in rat aortic smooth muscle (RASM) cells. In primary and immortalized RASM cells, up-regulation of p53 expression or increase in activity with doxorubicin inh...

Knowing the tertiary structure of proteins is important to predict protein function and to achieve rational drug design. However, huge amounts of money and time are needed to determine tertiary structures by experimental method. Only a small number of protein structures have been experimentally determined; therefore, prediction of the tertiary structure of proteins by computer should be of grea...

OBJECTIVE To determine whether preclinical Alzheimer disease (AD), as detected by the amyloid-imaging agent Pittsburgh Compound B (PiB) in cognitively normal older adults, is associated with risk of symptomatic AD. DESIGN A longitudinal cohort study of cognitively normal older adults assessed with positron emission tomography (PET) to determine the mean cortical binding potential for PiB and ...

AIMS To examine the effectiveness of the Montreal Cognitive Assessment (MoCA) to screen people with mild cognitive impairment (MCI), to associate the MoCA score with the presence of infarction, and to detect the characteristics of people with very mild subcortical vascular dementia (vmSVD). METHODS 392 out of 886 community dwellers aged 75 years and above living in Kurihara, Northern Japan, a...
