Primary Carcinoma of the liver is a rare disease in Iran like most parts of the world.  The incidence of this disease is about 2-8 times more in male than female but in Iran the ratio is almost equal between the two sexes.  The highest incidence in this country is in the age groups of 41-50 and 51-60. This seems to be in a lower age group in comparison to the United Slates as well as in other...

OBJECTIVES We examined self-reported health among formerly incarcerated mothers. METHODS We used data from the Fragile Families and Child Wellbeing Study (n = 4096), a longitudinal survey of mostly unmarried parents in urban areas, to estimate the association between recent incarceration (measured as any incarceration in the past 4 years) and 5 self-reported health conditions (depression, ill...

The use of pharmacological agents in intensive care units (ICUs) is ever on the increase, with novel therapies appearing in the literature regularly. The complexities of polypharmacy are a challenge to the intensivist, and any guidance as to which drugs to use, when to use them and how much to use is always welcome. Happily, therefore, over the past 2 months a number of interesting papers and a...

Speech errors reflect linguistic knowledge. For example, phonological errors follow languagewide phonotactic constraints such as the fact that [h] must be an onset in English. We review five experimental studies that demonstrate that errors adhere to artificial experiment-wide constraints (e.g. [f] must be an onset during this experiment) as well as language-wide constraints. These studies show...

In this work we report spectrophotometric observations of a planetary nebula sample towards the galac-tic bulge. A total of 45 PNe was observed and their physical parameters (electron density and temperature) were derived. Ionic abundances were calculated using a three-level atom model and abundances were derived through ionisation correction factors. Results show low abundance objects at high ...

BY DEFINITION, a validated supercentenarian is a properly documented centenarian who has lived to be at least the age of 110 years. The tables reproduced below and various other tables of supercentenarians are regularly updated by Dr. Stephen Coles, one of the members of our Editorial Board, along with other members of the Los Angeles Gerontology Research Group (GRG). For further details, pleas...

The genomes of the nematodes Caenorhabditis elegans and Caenorhabditis briggsae both contain approximately 100,000 introns, of which >6,000 are unique to one or the other species. To study the origins of new introns, we used a conservative method involving phylogenetic comparisons to animal orthologs and nematode paralogs to identify cases where an intron content difference between C. elegans a...
