We have made observations of the dark cloud, B5 in the transitions of H 2 CO, J = 1 10 1 11 ,and 2 12 ! 1 11. We compared the H 2 CO result with the observational results of CO and with the visual extinction. There exists an overall correspondence of molecules and extinction. However, a detailed agreement is lacking. We discussed the kinematics and the spatial relationship of molecules and exti...

Nonneoplastic cell lines are unable to grow in soft agar. However, concomitant treatment of these cells with epidermal growth factor and transforming growth factor ßconfers upon them anchorage independence. Since articular chondrocytes are unique as normal diploid cells that do have the capability of growing in soft agar, we tested whether transforming growth factor ßand epidermal growth fact...

Imagining sustainable food futures is key to effectively transforming systems. Yet even transdisciplinary approaches struggle open up complex and highly segregated policy governance for co-production can fail critically interrogate assumptions, worldviews, values. In this Perspective we argue that processes concerned with system transformation need meaningufully engage critical futures, do so t...

If the reduction of CO could be achieved photochemically it would represent a rather new type of artificial photosynthesis since in distinction to H2 as a result of photochemical water splitting, methanol is well suited for storage and transportation. As an energy-rich liquid it offers many benefits [1]. Metal carbonyl complexes should be attractive candidates for this purpose. Unfortunately, m...

Transforming growth factor-beta, a potent modulator of cell function, induces fibroblasts cultured on plastic to increase collagen synthesis. In 5- and 7-day porcine skin wounds, which have minimal to moderate collagen matrix, respectively, transforming growth factor-beta and type I procollagen were coordinately expressed throughout the granulation tissue. However, in 10-day collagen-rich granu...

Traditionally, the receiver operating characteristic (ROC) curve for a diagnostic test plots true positives (sensitivity) against false positives (one minus specificity). However, this representation brings with it several drawbacks. A transformation to positive and negative likelihood ratio co-ordinates, scaled by base-ten logarithms, offers several advantages. First we motivate the use of pos...

The present note is a recollection of the most striking and useful applications of co/end calculus. We put a considerable effort in making arguments and constructions rather explicit: after having given a series of preliminary definitions, we characterize co/ends as particular co/limits; then we derive a number of results directly from this characterization. The last sections discuss the most i...

conclusions based on our study, in vivo prepared e/sa may be considered as a good candidate for animal immunization. results our results showed that the serum levels of anti-e/sa immunoglobulins significantly increased in all of the immunized groups. the differences of the serum levels of tgf-β between the groups were statistically significant at days 28 and 56 after immunization with e/sa. bac...

background: transforming growth factor-β1 (tgf-β1) has been found to play a crucial role in early central nervous system development. several studies have illustrated decreased tgf-β1 levels in sera and brains of autistic children. two point mutations in the tgf-β1 signal peptide at 869t/c and 915g/c have been reported to influence tgf-β1 expression. the aim of the present study was to investig...
