INTRODUCTION Colonic perforation is a clinical condition which occurs due to variety of reasons, such as intrinsic disorders of the intestine, extrinsic causes, but also due to presence of foreign bodies. Foreign objects enter gastrointestinal tract by oral or transanal introduction. CASE REPORT we present an uncommon case of a 26- year-old tetraplegic male, whose death was a consequence of a...

Protein isolates of pumpkin (Cucurbita pepo L) seeds were hydrolyzed by acid protease to prepare antioxidative peptides. The hydrolysis conditions were optimized through Box-Behnken experimental design combined with response surface method (RSM). The second-order model, developed for the DPPH radical scavenging activity of pumpkin seed hydrolysates, showed good fit with the experiment data with...

Hybridization between crops and their weedy or wild relatives is an area of concern because the widespread use of genetically engineered crops may allow novel, bene®cial transgenes to enter nearby populations. We compared ®tness components of wild Cucurbita pepo from Arkansas, USA, with wild±crop hybrids derived from yellow squash (a cultivar of C. pepo with transgenic resistance to two viruses...

Microorganisms are ubiquitous and thought to regulate host populations. Although microorganisms can be pathogenic and affect components of fitness, few studies have examined their effects on wild plant populations. As individual traits might not contribute equally to changes in population growth rate, it is essential to examine the entire life cycle to determine how microorganisms affect host p...

Squash (Cucurbita pepo L. var. melopepo torticalis, Bailey) leaves were supplied with (14)C-sucrose, then specific radioactivities of the glucose and galactose moieties of translocated stachyose were determined. In every case, the specific radioactivity of the galactose moiety was greater than that of the glucose moiety. It is concluded that the stachyose was not synthesized at either the phloe...
