Tissue inhibitor of metalloproteinases-1 (TIMP-1) recently emerged as a pro-metastatic factor highly associated with poor prognosis in a number of cancers. This correlation seemed paradox as TIMP-1… (More)
BACKGROUND
To analyze the accuracy and inter-observer variability of image-guidance (IG) using 3D or 4D cone-beam CT (CBCT) technology in stereotactic body radiotherapy (SBRT) for lung tumors.

The purpose of this study was the mathematical analysis of IMRT with many non-coplanar fields for planning target volumes (PTV) surrounding nearly spherical organs at risk (OAR). Our approach is… (More)
By labeling HS 1500 with a radioactive 14C, it was proven that after oral application and under certain circumstances, low amounts of low molecular humic acids are for a short time absorbed from the… (More)
Influences of the low molecular humic substance HS 1500 on parameters of organs (testis weight, epididymis weight), FSH-, and LH-levels in plasma as well as on the spermatogenesis of male rats were… (More)
The influence of a low molecular synthetic humic substance (HS 1500) on pre- and postnatal development of rats was investigated. After oral application of 1000 mg/kg and 2000 mg/kg b. w. HS 1500… (More)
Naturally occurring humic substances are particular chemical compounds which are found in humus. They bind to carbohydrates, amino acids and steroids by means of hydrogen bonds, covalent bonds and… (More)
Implanted bovine apatite is highly osteoconductive, since it serves the host tissue as a “guide-line” for the deposition of newly developing bone tissue. It is well tolerated, but it showed no signs… (More)
