0037 Molecular Markers Of Biological Aging In Predicted Short-lived Flies

Aging in a very short-lived nematode.

Aging has been characterised in detail in relatively few animal species. Here we describe the aging process in free-living adults of the parasitic nematode Strongyloides ratti. We find that the phenomenology of aging in S. ratti free-living females, resembles that of the short-lived free-living nematode Caenorhabditis elegans, except that it unfolds far more rapidly. The mean (3.0 +/- 0.1 days)...

investigation of (meta)discourse markers in elt coursebooks

the present study aimed to investigate representation of discourse markers and metadiscourse markers in conversations and readings of general elt coursebook series used in the language centers of iran. to this aim, four elt coursebooks popularly taught in language centers of this country were analyzed based on fung and carter’s (2007) framework regarding discourse markers and hyland’s (2005) fr...

Insulin resistance and cognitive aging in long-lived and short-lived mice.

To the Editor: In a recent Future History article in this Journal, Rasgon and Jarvik (1) suggested that insulin resistance may facilitate the onset of Alzheimer's disease (AD) and may provide a mechanistic link between affective disorders and AD. In this context, it may be interesting to examine the association between alterations in insulin signaling and in cognitive aging in mice with major, ...

Molecular Markers in Neuroblastoma

Neuroblastoma, one of the common malignant childhood tumors, arises from neuroblast cells derived from theneural crest and destined for the adrenal medulla and the sympathetic nervous system and shows remarkable biologicalheterogeneity, resulting in favorable or unfavorable outcomes. Some tumors make rapid progress with a fataloutcome. In other instances, the tumors regress spontaneously in inf...
