TL;DR: Skin-to-skin contact is a remarkably potent intervention against the pain experienced during heel stick in newborns, and crying and grimacing were reduced from control infant levels during the heel lance procedure.
Abstract: Objectives. To determine whether skin-to-skin contact between mothers and their newborns will reduce the pain experienced by the infant during heel lance. Design. A prospective, randomized, controlled trial. Setting. Boston Medical Center, Boston, Massachusetts. Participants. A total of 30 newborn infants were studied. Interventions. Infants were assigned randomly to either being held by their mothers in whole body, skin-to-skin contact or to no intervention (swaddled in crib) during a standard heel lance procedure. Outcome Measures. The effectiveness of the intervention was determined by comparing crying, grimacing, and heart rate differences between contact and control infants during and after blood collection. Results. Crying and grimacing were reduced by 82% and 65%, respectively, from control infant levels during the heel lance procedure. Heart rate also was reduced substantially by contact. Conclusion. Skin-to-skin contact is a remarkably potent intervention against the pain experienced during heel stick in newborns.

TL;DR: The hypothesis is presented that, whatever the origin and other functions of angiosperms, insect pollination and closed carpels may, in combination, reduce the influence of random variation on pollen tube competition, thus enhancing the ability of natural selection to act on the gametophytic phase of the life cycle.
Abstract: In the primitive angiosperms, closed carpels are believed to have evolved as protection for ovules, which would otherwise be injured by animal pollinators. The hypothesis is presented that, whatever the origin and other functions of angiosperms, insect pollination and closed carpels may, in combination, reduce the influence of random variation on pollen tube competition, thus enhancing the ability of natural selection to act on the gametophytic phase of the life cycle. The microgametophytic phase represented by vast numbers of haploid individuals can then serve, by insect pollination and closed carpels, as a screen against any genome not functioning with a high degree of metabolic vigor. Poorly balanced genomes could thus be eliminated at relatively little cost. Insect-pollinated angiosperms would therefore benefit from positive aspects of sexual recombination. Such a system may have allowed the angiosperms to undergo their rise to dominance.

TL;DR: The term small bowel bleeding is proposed as a replacement for the previous classification of obscure GI bleeding (OGIB), and it is recommended that the term OGIB should be reserved for patients in whom a source of bleeding cannot be identified anywhere in the GI tract.

TL;DR: It is proved that neural crest cells from other regions of the head can mimic the development of periocular crest cells, and proves that the environment through which these cells migrate plays an essential role in establishing the timing and spatial patterns of their movement.

TL;DR: Increasing the understanding of how physical properties of food systems impact lipid oxidation could lead to the development of novel antioxidant technologies that not only protect the oil against oxidation and increase shelf-life but also allow food manufacturers to include more nutritionally beneficial fatty acids in their products.
Abstract: Lipid oxidation is important to food manufacturers especially when they increase unsaturated lipids in their products to improve nutritional profiles. Unfortunately, the number of antioxidants available to food manufacturers to control oxidative rancidity is limited and the approval of new antioxidants is unlikely due to economic barriers in obtaining government approval for new food additives. Therefore, new antioxidant technologies are needed for food oils. This paper reviews the current knowledge of lipid oxidation in foods with emphasis on how physical properties of food systems impact oxidation chemistry. In particular, the role of association colloids in bulk oils on lipid oxidation chemistry is discussed in an attempt to understand mechanisms of oxidation. Increasing the understanding of how physical properties impact lipid oxidation could lead to the development of novel antioxidant technologies that not only protect the oil against oxidation and increase shelf-life but also allow food manufacturers to include more nutritionally beneficial fatty acids in their products.
