Fingers lay fibers n page 553, Canty et al. show how cells use finger-like projections to lay down parallel arrays of collagen fibers that are many times the lengths of the cells. Parallel arrays of long collagen fibers give tendons their resistance and tensile properties. Thousands of collagen molecules self-assemble into fibers, but the fibers need instruction from their environment for align...

in order to determine the effects of water deficit at different growth stages of sugar beet and optimal usage of water on quality and quantity characters of sugar beet, a factorial experiment based on randomized complete block design was conducted with 13 treatments and four replications in 2000 and 2001 in agricultural research center of hamadan. for the first factor, irrigation withheld in th...

Allitol, D-talitol and L-iditol are sugar alcohols that are rare in nature. Due to their previous rarity, little is known about the laxative effects of these rare sugar alcohols. Therefore, reliable data on the laxative effect that these sugar alcohols cause in experimental animals could help to evaluate the effectiveness of new monosaccharide laxative drugs. To investigate the laxative effect ...

OBJECTIVE To investigate added sugar intake, main dietary sources and factors associated with excessive intake of added sugar. METHODS A population-based household survey was carried out in São Paulo, the largest city in Brazil. Cluster sampling was performed and the study sample comprised 689 adults and 622 elderly individuals. Dietary intake was estimated based on a 24-hour food recall. Usu...

Molasses, the main byproduct of sugar production, is a well-known source of antioxidants. In this study sugar cane molasses (SCM) and sugar beet molasses (SBM) were investigated for their phenolic profile and in vitro antioxidant capacity and for their protective effect in human HepG2 cells submitted to oxidative stress. According to its higher phenolic concentration and antioxidant capacity in...
