The vertebrate heart develops from two distinct lineages of cardiomyocytes that arise from the first and second heart fields (FHF and SHF, respectively). The FHF forms the primitive heart tube, while adding cells from the SHF allows elongation at both poles of the tube. Initially seen as an exclusive characteristic of higher vertebrates, recent work has demonstrated the presence of a distinct F...

We examined the effects of macroeconomic performance and social policy on the extent and depth of poverty in America using state-level panel data from the 1981-2000 waves of the Current Population Survey. We found that a strong macroeconomy at both the state and national levels reduced both the number of families who were living in poverty and the severity of poverty. The magnitude and source o...

BACKGROUND Women-headed families tend to be the most marginalized and poverty prone in any given community. One in 10 Iraqi households is headed by woman according to International Organization for Migration, though their assessments suggest that this ratio rises to 1 in 8 in displaced families. OBJECTIVE To draw attention to the exposure and vulnerability of women headed families to key medi...

BACKGROUND RNA sequences of the recently identified hepatitis GB virus C (HGBV-C), also named hepatitis G virus (HGV), have been detected in patients with idiopathic fulminant hepatic failure (FHF) but the role of this agent in the disease remains controversial. AIMS To investigate the presence and implications of HGV infection in a large series of Spanish patients with FHF. PATIENTS Sixty ...

The Formosan subterranean termite, Coptotermes formosanus Shiraki, is an invasive species that originated in China and has been introduced to Hawaii and the U.S. mainland. Colonies are headed either by a pair of reproductives (simple families) or by varying numbers of inbreeding reproductives (extended families), and therefore have variable degrees of inbreeding. Worker size also varies among c...

This study analyzes the effect of one-child policy on marriage market in China and focuses leftover situation, age, age differential between husband wife. Considering 30 years as cutoff point, has increased proportion to about 1.2%, with 1.8% men 0.6% women.

A search through the Cambridge Structural Database (CSD) for crystal structures containing the [FHF] ́ anion was carried out. Forty five hydrogen bifluoride structures were found mainly with the H-atom moved from the mid-point of the F . . . F distance. However several [FHF] ́ systems characterized by D8h symmetry were found, the same as this anion possesses in the gas phase. The analysis of CSD ...
