The naturally occurring neurotoxin, 1-methyl-6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline (salsolinol; SAL), has been speculated to contribute to Parkinson's disease and neuropathology of chronic alcoholism. In the present study, we found the capability of SAL to cause DNA cleavage in the presence of Cu(ll). Incubation of SAL and CuCl2 with calf thymus DNA caused strand breaks. Likewise, SAL in...

The LL-D05139 complex, containing LL-D05139 beta and azaserine, was recovered from the fermentation filtrate of Glycomyces harbinensis (NRRL 15337). A chemically defined medium was developed which favored the production of LL-D05139 beta. Antibiotic LL-D05139 beta was isolated from the fermentation filtrate by adsorption on granular carbon and further purified by chromatography on microcrystall...

Pseudomonas aeruginosa is a highly versatile opportunistic pathogen and its ability to produce biofilms is a direct impediment to the healing of wounds and recovery from infection. Interest in anti-microbial peptides (AMPs) has grown due to their potential therapeutic applications and their possible use against antibiotic resistant bacteria. LL-37 is the only cathelicidin expressed by humans. I...

LL-37 is a human cationic host defense peptide (antimicrobial peptide) belonging to the cathelicidin family of peptides. In this study, LL-37 was shown to kill stimulated CD8(+) T cells (Cytotoxic T lymphocytes; CTLs) via apoptosis, while having no cytotoxic effect on non-stimulated CD8(+) or CD4(+) T cells or stimulated CD4(+) T cells. Of interest, the CD8(+) cells were much more sensitive to ...

This paper is an overview of existing applications of Linear Logic (LL) to issues of computation. After a substantial introduction to LL, it discusses the implications of LL to functional programming, logic programming, concurrent and object-oriented programming and some other applications of LL, like semantics of negation in LP, non-monotonic issues in AI planning, etc. Although the overview c...

Adipose stem cell-conditioned medium may promote human dermal fibroblast (HDF) proliferation and migration by activating paracrine peptides during the re-epithelization phase of wound healing. Human antimicrobial peptide LL-37 is upregulated in the skin epithelium as part of the normal response to injury. The effects of conditioned medium (CM) from LL-37 treated adipose stem cells (ASCs) on cut...

This study examines the effects of a combined modality regimen of long duration-low temperature whole body hyperthermia (6 h at 40.0 degrees C; LL-WBH), recombinant human tumor necrosis factor-alpha (TNF) and carboplatin (CBDCA) on a transplantable fibrosarcoma as well as normal tissue. We compare LL-WBH with short duration-high temperature whole body hyperthermia (2 h at 41.5 degrees; SH-WBH)....
