PURPOSE This study investigated ocular surface components that contribute to matrix-metalloproteinase (MMP)-2 and MMP-9 found in tears following corneal epithelial wounding. METHODS Laboratory short-haired cats underwent corneal epithelial debridement in one randomly chosen eye (n = 18). Eye-flush tears were collected at baseline and during various healing stages. Procedural control eyes (ide...

Various biochemical signals are implicated in Arabidopsis wound signalling, including jasmonic acid (JA), salicylic acid, auxin, and Ca2+. Here, we report on cross-talk of phytohormones with phosphoinositide signals not previously implicated in plant wound responses. Within 30 min of mechanical wounding of Arabidopsis rosette-leaves, the levels of the lipid-derived soluble inositolpolyphosphate...

In response to mucosal injury, epithelial cells modify the patterns of expressed genes to repair damaged tissue rapidly. Our previous studies have demonstrated that the transcription factor c-Myc is necessary for stimulation of epithelial cell renewal during mucosal healing, but the up-stream signaling initiating c-Myc gene expression after injury remains unknown. Wnts are cysteine-rich glycopr...

The Solanaceae plants produce a variety of interesting biologically active products including the steroid alkaloids solanidine, nicotine and tropane alkaloids. Putrescine N-methyltransferase (PMT) is an enzyme that catalyses s-adenosylmethionine-dependent methylation of putrescine in one of the primary steps of nicotine and tropane alkaloids biosynthesis pathway. Two tobacco members of the AP2/...

Visitor effect studies have had inconsistent results, due in part to the inability control for all confounding variables such as time of day, seasonal weather patterns, and so forth. This study represents first instance where chimpanzee (Pan troglodytes) wounding frequencies were investigated across extensive periods presence complete absence visitors, thus eliminating many visitor-related vari...

Potato (Solanum tuberosum L.) is a worldwide food staple, but substantial waste accompanies the cultivation of this crop due to wounding of the outer skin and subsequent unfavorable healing conditions. Motivated by both economic and nutritional considerations, this metabolite profiling study aims to improve understanding of closing layer and wound periderm formation and guide the development of...

This paper develops an agenda for political geographical work on violence, war, and trauma. Drawing from analysis of the Great March Return, a series mass demonstrations in Gaza Strip 2018 2019, it argues that geography related fields could be enriched by concepts enduring violence wounding. Enduring is offered as supplement to existing slow cognate such ‘everyday’, banal′, ‘chronic’ offering f...

In the present study, we identified chitinase genes in the genome of mulberry for the first time. The mulberry genome encodes 20 chitinase genes, which are grouped into two main families and organized into five classes. The genomic structures and phylogenetic relationships of mulberry chitinase genes were analyzed, which provided a genetic basis for understanding the functions of these genes. W...
