The New and Early Chick (EC) methods, two commonly used techniques for ex ovo culture of early-stage avian embryos, are limited by poor survivability after initiation of circulation. This limitation is circumvented with two recent technical advancements: the modified Cornish pasty culture and whole-embryo transplantation. The former supports optimal ex ovo growth till stage HH18, and the latter...

In recent years, important gains and changes have been observed in the life of teenagers with Down syndrome (DS) with increased inclusion into society. This review will discuss adolescence and sexuality in teenagers with DS from a descriptive study of 50 patients with DS between the ages of 10 and 20 years. The mean age was 13.5 years, 50% females; 86% went to school with 62.2% in school for ov...

The implementation of MELD and PELD represented an enormous advance toward allocation of deceased donor livers according to objective criteria that reflect illness severity. PELD, developed using the Studies of Pediatric Liver Transplantation database, formed the basis of liver allocation for children (<18 years) (1). To acknowledge that a mathematical model cannot adequately reflect every indi...

A restriction map of a 13.5-kb EcoRI fragment encoding beta-lactamase from a plasmid isolated from enterococcal strain PA was prepared and found to differ markedly from the published maps of beta-lactamase-encoding EcoRI fragments of two staphylococcal plasmids and the plasmid from enterococcal strain HH22. This comparison also showed that one of two contiguous EcoRV fragments that encompass th...

Attempts to understand the causes of chronic poverty have largely centred on the concept of the poverty trap. In this perspective, the main focus is on the paucity of initial wealth or endowments, which under certain plausible conditions can create a trap from which a poor person will find it hard to escape without help from outside. While acknowledging the value of insights gained from this pe...

For the last 40 years, researchers have collected cases of children who claim to remember previous lives. In a minority of these cases, the subjects also claim to remember events that took place during the intermission between the end of their previous life and their birth in the current life. Subjects in these cases tend to make more verified statements about the previous life they claim to re...

ABSTRACT Bioorthogonal ligations have emerged as highly versatile chemical tools for biomedical research. The exceptionally fast reaction between 1,2,4,5-tetrazines and trans-cyclooctenes (TCOs), also known as tetrazine ligation, is frequently used in this regard. Growing numbers of applications for the tetrazine ligation led to an increased demand for TCO compounds, whose commercial availabili...

PROBLEM India has the world's largest number of maternal deaths estimated at 117,000 per year. Past efforts to provide skilled birth attendants and emergency obstetric care in rural areas have not succeeded because obstetricians are not willing to be posted in government hospitals at subdistrict level. APPROACH We have documented an innovative public-private partnership scheme between the Gov...
