This paper reviews the availability of local, state, and national data on family structure, stability, andthe well-being of children. It focuses on indicators of family structure and stability, but it also briefly reviewsthe literature on the effects of family structure and stability on child, adolescent, and early adult outcomes. Themajor themes of the paper are: (1) family structu...

OBJECTIVE To clarify the incidence and predictive risk factors of cervical spine instabilities which may induce compression myelopathy in patients with rheumatoid arthritis (RA). METHODS Three types of cervical spine instability were radiographically categorized into "moderate" and "severe" based on atlantoaxial subluxation (AAS: atlantodental interval >3 mm versus ≥10 mm), vertical subluxati...

BACKGROUND Since the introduction of polio vaccines in the 1950's and 60's, eradication of poliovirus from the world has been technically feasible. Progress towards this goal, however, has been uneven and influenced by social and political factors that challenge the implementation of robust immunization programs. While violence and insecurity are often cited as barriers to eradication, current ...

this paper presents a model of a catchment area in northwest of iran. the researchers have studied ajichai basin which is located in the east part of orumiyeh lake, located at the longitude of 47 52’ e to 45 32’ e and the latitude of 37 26’ n to 38 30’ n. the researchers have chosen the data from tabriz upper air station which is the only one in the area. the research data are seven instability...

This paper extends the model of Fielding (1999), which is designed to explain changes in investment in South Africa during the Apartheid period, by allowing a role for indicators of political instability and political and civil rights, as measured by Fedderke et al. (1999). The conclusions based on estimation of the original model are robust to the inclusion of the political factors, but these ...

We report the functional and temporal relationship between cellular phenotypes such as oxidative stress, p38MAPK-dependent responses and genomic instability persisting in the progeny of cells exposed to sparsely ionizing low-Linear Energy Transfer (LET) radiation such as X-rays or high-charge and high-energy (HZE) particle high-LET radiation such as (56)Fe ions. We found that exposure to low an...

BACKGROUND The BRAF(V600E) mutation is the most common genetic alteration in papillary thyroid carcinomas (PTCs). Transgenic mice overexpressing BRAF(V600E) in their thyroids under control of the thyroglobulin promoter (Tg-BRAF2 mice) developed invasive PTCs with high penetrance. However, these mice showed elevated thyrotropin (TSH) levels, which also stimulate the proliferation of thyrocytes a...

Some extended false discovery rate (FDR) controlling multiple testing procedures rely heavily on empirical estimates of the FDR constructed from gene expression data. Such estimates are also used as performance indicators when comparing different methods for microarray data analysis. The present communication shows that the variance of the proposed estimators may be intolerably high, the correl...
