Activated STAT3 plays an important role in oncogenesis by stimulating cell proliferation and resisting apoptosis. STAT3 therefore is an attractive target for cancer therapy. We have screened a traditional Chinese herb medicine compound library and found Eriocalyxin B (EB), a diterpenoid from Isodon eriocalyx, as a specific inhibitor of STAT3. EB selectively inhibited constitutive as well as IL-...

IMPORTANCE Epidermolysis bullosa (EB) pruriginosa is a rare variant of dystrophic EB. It may manifest late in life and is characterized by intense pruritus, resulting in a phenotype resembling acquired inflammatory dermatoses. Dermatopathology textbooks include hereditary forms of EB among the "cell-poor" list of subepidermal blistering disorders. OBSERVATIONS We report a case of dominant dys...

OBJECTIVE This population-based study aimed (1) to test the presence of an association between regular voluntary exercise behaviour (EB) that is performed in leisure time and body mass index (BMI) in youth and (2) to investigate the causal nature of this association using a longitudinal design in genetically informative subjects. DESIGN AND METHODS Both EB and BMI were assessed repeatedly ove...

Ethidium bromide (EB) is a commonly used probe for fluorescence detection and quantification of nucleic acids, since EB forms a highly luminescent complex with dsDNA. Typical detection sensitivity of EB-based assays to dsDNA in solution is about 0.1 lg. With the aim to increase the sensitivity of EB assays we have employed the Metal-Enhanced Fluorescence technology. We show that deposition of t...

The effect of ethidium bromide (EB) on the synthesis of circular DNA of mammalian cells was studied by isopycnic centrifugation in a CsCl-EB solution. EB (0.1 —0.5 ^wg/ml) interferes with the synthesis of newly-formed circular D N A of HeLa cell mitochondria and causes degradation of the pre-existing circular DNA, as well. Under the same conditions, nuclear DNA synthesis was not inhibited. This...

EB is a trace-based formal language created for the specification of information systems (IS). Attributes, linked to entities and associations of an IS, are computed in EB by recursive functions on the valid traces of the system. In this paper, we show how to synthesize relational database transactions that correspond to EB attribute definitions. Thus, each EB action is translated into a transa...

Epidermolysis bullosa (EB) is an inherited connective tissue disease causing blisters in the skin and mucosal membranes. In severe cases, EB may be associated with renal damage through several mechanisms, mainly immunological ones. The present case described a young male with dystrophic recessive EB who developed an advanced chronic renal damage secondary to tubulointerstitial nephritis that wa...

1,25-Dihydroxyvitamin D(3) and vitamin D(3) analogues, such as EB 1089, potentiate the response to ionizing radiation in breast tumor cells. The current studies address the basis for this interaction by evaluating DNA damage and repair, the effect of interference with reactive oxygen generation, the involvement of p53 and caspase-3, signaling through c-myc, as well as the induction of senescenc...

Existing methods for estimating individual dairy cow energy balance typically either need information on feed intake, that is, the traditional input-output method, or frequent measurements of BW and body condition score (BCS), that is, the body reserve changes method (EB(body)). The EB(body) method holds the advantage of not requiring measurements of feed intake, which are difficult to obtain i...
