Humanitate eta Gizarte Zientzien arloko Irakasleak Prestatzeko Masterra egiten ari diren ikasleek gizarteaz gizarteak irakaskuntzari buruz duen ikuspegiaz gogoeta egin behar luketela iritzita, eta, horrenbestez, halaber irakaskuntzaren gizarte-testuingurua zein den kontuan hartu hartuta, hiru galderari erantzuten saiatu genuke: 1) Zein da gizarte-ezagutzaren funtzioa gaur egun? 2) Zergatik zert...

The novel core–shell microparticles were fabricated to deliver curcumin by using hydrophobic zein as the core and hydrophilic cellulose nanocrystals (CNCs) shell. Different concentrations (0.10–1.50%, w/v) of CNCs utilized regulate microstructure, physicochemical stability, in vitro digestion microparticles. size ranged from 1017.3 3663.7 nm. Electrostatic attraction interactions responsible fo...

Lysine-ketoglutarate reductase catalyzes the first step of lysine catabolism in maize (Zea mays L.) endosperm. The enzyme condenses l-lysine and alpha-ketoglutarate into saccharopine using NADPH as cofactor. It is endosperm-specific and has a temporal pattern of activity, increasing with the onset of kernel development, reaching a peak 20 to 25 days after pollination, and there-after decreasing...

573 abortuses, prenatal deaths, and infants dying before their first birthday. I highly recommend this book to anyone caring for families with questions concerning a malformed fetus, abortus, stillborn, or deceased newborn. The contributors to the second volume in this rapid publication series on recombinant DNA technology have successfully covered a wide range of important topics and concepts ...

An interesting question in maize development is why only a single zein gene is highly expressed in each of the 19-kDa zein gene clusters (A and B types), z1A2-1 and z1B4, in the immature endosperm. For instance, epigenetic marks could provide a structural difference. Therefore, we investigated the DNA methylation of the arrays of gene copies in both promoter and gene body regions of leaf (non-e...

The present study evaluates the interactive effects of protein quality and the ratio of protein to digestible carbohydrate on herbivore performance, various aspects of nutritional homeostasis (feeding and post-ingestive regulation) and food choice. In the first experiment, final-instar caterpillars of generalist-feeding African cotton leafworm Spodoptera littoralis (Boisduval) (Lepidoptera: Noc...

BACKGROUND One of the goals of plant breeding is to create crops to provide better nutrition for humans and livestock. Insufficient intake of protein is one of the most severe factors affecting the growth and development of children in developing countries. More than a century ago, in 1896, Hopkins initiated the well-known Illinois long-term selection for maize seed protein concentration, yield...

Methylphenidate (MPH, Ritalin), has been prescribed to treat attention deficit/hyperactivity disorder (ADHD) since its approval by the FDA over 50 years ago. Diagnoses of pediatric patients with ADHD and the administration of MPH to treat the symptoms have increased in prevalence in recent years. A 2005 study by El-Zein et al. reported statistically significant increases in cytogenetic anomalie...

Background The use of biopolymers is increasing in drug delivery, thanks to the peculiar properties of these compounds such as their biodegradability, availability, and the possibility of modulating their physico-chemical characteristics. In particular, protein-based systems such as albumin are able to interact with many active compounds, modulating their biopharmaceutical properties. Zein is a...
