BACKGROUND Vitamin A (VA) deficiency induces a type 1 cytokine response and exogenously provided retinoids can induce a type 2 cytokine response both in vitro and in vivo. The precise mechanism(s) involved in this phenotypic switch are inconsistent and have been poorly characterized in humans. In an effort to determine if retinoids are capable of inducing(More)
Elevated levels of homocysteine (Hcy) have been identified as independent risk identifiers for cardiovascular disease, cerebrovascular disease as well as for all-cause mortality. Despite the potential importance of these observations, a definitive pathological role for Hcy or its various metabolites in any of these conditions has not been established.(More)
The capacity of a brass instrument to generate sounds with strong high-frequency components is dependent on the extent to which its bore profile supports nonlinear sound propagation. At high dynamic levels some instruments are readily sounded in a "cuivré" (brassy) manner: this phenomenon is due to the nonlinear propagation of sound in ducts of the(More)
BACKGROUND We have recently demonstrated that all-trans-retinoic acid (ATRA) and 9-cis-retinoic acid (9-cis RA) promote IL-4, IL-5 and IL-13 synthesis, while decreasing IFN-gamma and TNF-alpha expression by activated human T cells and reduces the synthesis of IL-12p70 from accessory cells. Here, we have demonstrated that the observed effects using ATRA and(More)

A reader's guide to the revised STKE review " Cycling of synaptic vesicles: How far? How fast? " , Over the past three years since the publication of the original version of this article, we have witnessed a wealth of new information regarding the pathways of synaptic vesicle cycling, which have been incorporated into the revised version of the Review.(More)
