The production of induced pluripotent stem (iPS) cells in 2006 by Takahashi and Yamanaka was a major breakthrough in stem cell research. IPS cells technology holds great promise for cell therapy, disease modelling, and drug testing, but it poses ethical questions concerning the moral status of somatic cells, which can re-gain pluripotency (iPS cells). This article provides an overview of the arguments that substantiate the debate on the moral assessment of iPS cells: potentiality argument; relational properties/standard view; and genetic basis for moral status...

Cochlear implantation has become a crucial approach for the treatment for patients with severe and profound sensorineural hearing loss. However, some patients would be embarrassed by the exterior components, which limited the patient's social activities. The idea of totally implantable cochlear implant (TICI) was put forward to alleviate these inconveniences. The implantable acoustical-electrical transducer would be a breakthrough in the study of TICI. In this paper, a summary of all kinds of designs ideas was made...

The period of British rule from 1757 to 1900 is marked by major sociopolitical changes and scientific breakthroughs that impacted medical systems, institutions, and practitioners in India. In addition, historians have debated whether the colonial regime used Western medicine as a tool to expand and legitimize its rule. This paper reviews the secondary literature on this subject with emphasis on the individual physicians. During this period, the practice of "Doctory" or Western medicine gained momentum in India, buoyed with the support of the British as well as Western-educated Indians...

In celebration of the anniversary of the Journal of Applied Psychology (JAP), we take a hundred-year journey to examine how the science of cross-cultural industrial/organizational psychology and organizational behavior (CCIO/OB) has evolved, both in JAP and in the larger field. We review broad trends and provide illustrative examples in the theoretical, methodological, and analytic advances in CCIO/OB during 4 main periods: the early years (1917-1949), the middle 20th century (1950-1979), the later 20th century (1980-2000), and the 21st century (2000 to the present)...

Despite decades of basic research, biliary diseases remain prevalent, highly morbid, and notoriously difficult to treat. We have, however, dramatically increased our understanding of biliary developmental biology, cholangiocyte pathophysiology, and the endogenous mechanisms of biliary regeneration and repair. All of this complex and rapidly evolving knowledge coincides with an explosion of new technological advances in the area of regenerative medicine. New breakthroughs such as induced pluripotent stem cells and organoid culture are increasingly being applied to the biliary system; it is only a matter of time until new regenerative therapeutics for the cholangiopathies are unveiled...

Physiological and molecular studies support the view that xylogenesis can largely be determined as a specific form of vacuolar programmed cell death (PCD). The studies in xylogenic zinnia cell culture have led to many breakthroughs in xylogenesis research and provided a background for investigations in other experimental models in vitro and in planta . This review discusses the most essential earlier and recent findings on the regulation of xylem elements differentiation and PCD in zinnia and other xylogenic systems...

Tiago R Matos, Menno A de Rie
A substantial part of ongoing research in experimental dermatology focuses on skin T cells - for that reason we find important to highlight the pioneering work of Jan D. Bos et al. from 1987 (The skin immune system (SIS): Distribution and immunophenotype of lymphocyte subpopulations in normal skin). This key article set the record straight, once and for all, about the presence of lymphocytes in healthy skin; characterized the immunophenotypes of subpopulations, quantified these cells, and studied their location...

The socialist factory, as the 'incubator' of the new socialist (wo)man, is a productive entry point for the study of socialist modernization and its contradictions. By outlining some theoretical and methodological insights gathered through field-research in factories in former Yugoslavia, we seek to connect the state of labour history in the Balkans to recent breakthroughs made by labour historians of other socialist countries. The first part of this article sketches some of the specificities of the Yugoslav self-managed factory and its heterogeneous workforce...

Autophagy was discovered more than half a century ago. In the early days, autophagy was studied mostly through the use of biochemical methods and electron microscopy. In the 1990s, yeast genetics was introduced to this field and brought about an exponential expansion. The 2016 Nobel Prize in Physiology or Medicine was eventually awarded to the scientist who spearheaded the rapid development of the field: Yoshinori Ohsumi. Here, I describe in a Nutshell how the autophagy machinery was discovered and how the autophagy research field has grown following the breakthroughs from yeast studies...

This review focuses entirely on the natural bengamides and selected synthetic analogues that have inspired decades of research. Bengamide A was first reported in 1986 from the sponge Jaspis cf. coriacea, and bengamide-containing sponges have been gathered from many biogeographic sites. In 2005, a terrestrial Gram-negative bacterium, Myxococcus virescens, was added as a source for bengamides. Biological activity data using varying bengamide-based scaffolds has enabled fine-tuning of structure-activity relationships...

There have been few major breakthroughs in heart failure (HF) drug therapies in recent years yet HF morbidity and mortality remain high, and there is a clear need for further research. Several newer agents that appear promising in Phase I and II trials do not progress to show clinical benefit in later trials. Part of the failure to find new therapies may lie in flawed trial design compounded by the need for ever-increasing patient numbers in order to prove outcome benefit. We summarize some of the most recent and promising medical therapies for HF...

Immuno-oncology (I/O) research has intensified significantly in recent years due to the breakthrough development and the regulatory approval of several immune checkpoint inhibitors, leading to the rapid expansion of the new discovery of novel I/O therapies, new checkpoint inhibitors and beyond. However, many I/O questions remain unanswered, including why only certain subsets of patients respond to these treatments, who the responders would be, and how to expand patient response (the conversion of non-responders or maximizing response in partial responders)...

Plant research is supported by an ever-growing collection of mutant or transgenic lines. In the past, a typical basic research laboratory would focus on only a few plant lines that were carefully isolated from collections of lines containing random mutations. The subsequent technological breakthrough in high-throughput sequencing, combined with novel and highly efficient mutagenesis techniques (including site-directed mutagenesis), has led to a recent exponential growth in plant line collections used by individual researchers...

Karin Pernebo, Kjerstin Almqvist
The negative impact of intimate partner violence (IPV) begins early in the child's relationship with a caregiver. Children's relationships with, and internal working models of, abused parents have rarely been documented. The aim of this study was to collect and interpret young children's accounts of their abused parent. Interviews were conducted with 17 children aged 4 to 12 years who had witnessed IPV. Thematic analysis identified three main themes and seven sub-themes: "Coherent accounts of the parent" (sub-themes of "general benevolence", "provision of support, protection, and nurture", and "parental distress"); "Deficient accounts of the parent" ("vague accounts" and "disorganized narrations"); and "The parent as a trauma trigger" ("avoidance" and "breakthrough of intrusive memories and thoughts")...

PURPOSE: United States (US) Pediatric Legislation (PL) was introduced in 1997 to improve children's health. The European Union PL (EUPL) has been in force since 2007. Both PLs facilitate additional pediatric research on primarily adult drugs. The EUPL declares that the forces of the market are not sufficient for children. Without a pediatric investigation plan, new drugs can no longer be registered with the European Union. New ways on how to facilitate drug development for rare pediatric diseases are being proposed...
