Importance: Governments worldwide have become increasingly cognizant of the spread of genetic discrimination (negative treatment or harm on the basis of actual or presumed genetic characteristics). Despite efforts by a number of governments to establish regulations addressing this phenomenon, public concern about genetic discrimination persists.
Objective: To identify key elements of an optimal genetic nondiscrimination policy and inform policymakers as they seek to allay genetic nondiscrimination and related public anxieties.
Objective: To assess the comparability of international ethics principles and practices used in regulating pediatric research as a first step in determining whether reciprocal deference for international ethics review is feasible. Prior studies by the authors focused on other aspects of international health research, such as biobanks and direct-to-participant genomic research. The unique nature of pediatric research and its distinctive regulation by many countries warranted a separate study.

The recipient's mucosal immune response against the donor's microbiota could be relevant factor in the effectiveness of FMT. Our aim was to design and validate an individualized immune-based test to optimize the fecal donor selection for FMT.

Despite its relevance, no efficient study designs to identify promising candidate biomarkers have been established. This has led to the proliferation of a myriad of exploratory studies using dissimilar strategies, most of which fail to identify any promising targets and are seldom validated.

The pillars of this legal framework are firstly, the duty to inform the donor in order to ensure that he or she is aware of the importance and the consequences of the donation; secondly, the control by ethics committees (RECs and External Ethics Committees of biobanks); and third, the supplementary application of the general rules on data protection. There are three different possibilities for processing samples (project, collection, and biobanks) - each one reinforcing specific consent or requiring other added guarantees.

Here we describe a comprehensive evaluation of the genomic landscape of 452 CLL cases and 54 patients with monoclonal B-lymphocytosis, a precursor disorder. We extend the number of CLL driver alterations, including changes in ZNF292, ZMYM3, ARID1A and PTPN11.

These exchanges are generally made under contractual material transfer agreements (MTAs). This paper asks what role, if any, should research ethics committees (RECs) play in ensuring legal and ethical conduct in such exchanges.

This article sheds light in this area by describing how the International Cancer Genome Consortium is developing policies and procedures to address the ethical and legal issues raised by the international transfer of data and results. These policies and procedures aim, first and most importantly, to safeguard the interests of the research participants and other involved stakeholders and, secondly, to facilitate the sharing of data and results to realize greater benefits from this kind of internationally collaborative genetic research.

Two major molecular subtypes can be distinguished, characterized respectively by a high or low number of somatic hypermutations in the variable region of immunoglobulin genes. The molecular changes leading to the pathogenesis of the disease are still poorly understood.

Systematic studies of more than 25,000 cancer genomes at the genomic, epigenomic and transcriptomic levels will reveal the repertoire of oncogenic mutations, uncover traces of the mutagenic influences, define clinically relevant subtypes for prognosis and therapeutic management, and enable the development of new cancer therapies.

The obtaining and use of genetic data have several particular implications for the rights of the patients and their relatives, and frequently practitioners and researchers face some new conflicts to which law and ethics try to give an answer. Some countries have enacted national laws related to genetic analysis. At the international level a great effort has been done to develop a common regulatory framework taking into account the rights of the patients/subjects of the research and other rights and interests.

The specific characteristics of genetic data lead to ethical-legal conflicts in the framework of genetic diagnosis. Several international organisations, including UNESCO and the Council of Europe, have enacted rules referring to the use of genetic information. This paper discusses possible legal and ethical criteria that could be used in genetic testing.

These chloro- and alkyl-alkene coordinated complexes react with CO and isocyanides [CNtBu, CN(2,6-Me2C6H3)] to give the ligand-substituted metal(III) compounds [M(eta5-Cp)[eta5-C5H4SiMe2(CH2CH=CH2)]XL] (X = Cl, Me, CH2Ph, CH2SiMe3). Reaction of the chloro-alkene tantalum complex with LiNHtBu results in formation of the imido hydride derivative [Ta(eta5-C5Me5)[eta5-C5H4SiMe2(CH2CH=CH2)]H(NtBu)].
