There is an increased desire for sophisticated foods, whereby consumers harbor higher expectations of health-promoting benefits above basic nutrition. Moreover, there is a move from the adulteration of foods with chemical preservatives toward biopreservation. Such expectations have led scientists to identify novel approaches to satisfy both demands, which utilize bacteriocin and peptide-based solutions. The best known examples of biopreservation involve bacteriocins. However, with the exception of nisin, bacteriocins have received limited use in the food industry. Peptides can be added to foods to improve consumer health. Some of the best known examples are angiotensin I–converting enzyme (ACE)-inhibitory peptides, which inhibit ACE, a key enzyme involved in blood pressure (BP) regulation. To be effective, these peptides must be bioavailable, but by their nature, peptides are degraded by digestion with proteolytic enzymes. This review critically discusses the use and potential of peptides and bacteriocins...
We review some outstanding puzzles and experimental anomalies in hadron physics that appear to challenge conventional wisdom and, in some cases, the foundations of quantum chromodynamics (QCD). We also discuss possible solutions and propose new tests and experiments that could illuminate th ... more
We review the methods developed for combining the parton shower approximation to quantum chromodynamics with fixed-order perturbation theory so as to achieve next-to-leading-order (NLO) accuracy for inclusive observables. These developments have made it possible to generate fully simulated ... more
General classes of mechanisms for generating small neutrino masses are surveyed from a top-down (superstring) perspective. In particular, string constructions have motivated various possibilities involving higher-dimensional operators, string instantons, and wave-function overlaps in large ... more
