How Semantics Connotations May Influence Concerns About Donation of Biospecimens.

Human biological specimen (biospecimen) donation is routinely requested for clinical care and research purposes. Successfully engaging patients and research participants in biospecimen donation depends on what they understand these initiatives entail, including their perceptions of risk. Human biospecimens are stored in facilities routinely referenced as biobanks or biorepositories, both of which labels are known to embody a variety of connotations.

Canadian policy on reporting breaches of research integrity: When should Research Ethics Boards be informed?

In Canada, institutions that receive research funding from the three federal granting agencies must establish research ethics boards (REBs) to review the ethical acceptability of research involving humans. Institutions are also expected to promote the responsible conduct of research, fostering researchers' abilities to act with integrity in the conduct of their research. Where a researcher fails to act with integrity in research with humans, institutional policies and procedures of the U15, Canada's most research-intensive universities, vary in the extent to which they involve their REBs in response to such breaches.

Ethical considerations in conducting surgical research in severe complicated intra-abdominal sepsis.

Background: Severe complicated intra-abdominal sepsis (SCIAS) has high mortality, thought due in part to progressive bio-mediator generation, systemic inflammation, and multiple organ failure. Treatment includes early antibiotics and operative source control. At surgery, open abdomen management with negative-peritoneal-pressure therapy (NPPT) has been hypothesized to mitigate MOF and death, although clinical equipoise for this operative approach exists.

Improving the process of research ethics review.

Background: Research Ethics Boards, or Institutional Review Boards, protect the safety and welfare of human research participants. These bodies are responsible for providing an independent evaluation of proposed research studies, ultimately ensuring that the research does not proceed unless standards and regulations are met.

Main Body: Concurrent with the growing volume of human participant research, the workload and responsibilities of Research Ethics Boards (REBs) have continued to increase.

The biobank for the molecular classification of kidney disease: research translation and precision medicine in nephrology.

Background: Advances in technology and the ability to interrogate disease pathogenesis using systems biology approaches are exploding. As exemplified by the substantial progress in the personalized diagnosis and treatment of cancer, the application of systems biology to enable precision medicine in other disciplines such as Nephrology is well underway. Infrastructure that permits the integration of clinical data, patient biospecimens and advanced technologies is required for institutions to contribute to, and benefit from research in molecular disease classification and to devise specific and patient-oriented treatments.

Glycogen synthase kinase 3 beta alters anxiety-, depression-, and addiction-related behaviors and neuronal activity in the nucleus accumbens shell.

Psychiatric disorders such as anxiety, depression and addiction are often comorbid brain pathologies thought to share common mechanistic biology. As part of the cortico-limbic circuit, the nucleus accumbens shell (NAcSh) plays a fundamental role in integrating information in the circuit, such that modulation of NAcSh circuitry alters anxiety, depression, and addiction-related behaviors. Intracellular kinase cascades in the NAcSh have proven important mediators of behavior.

Visual adaptation enhances action sound discrimination.

Prolonged exposure, or adaptation, to a stimulus in 1 modality can bias, but also enhance, perception of a subsequent stimulus presented within the same modality. However, recent research has also found that adaptation in 1 modality can bias perception in another modality. Here, we show a novel crossmodal adaptation effect, where adaptation to a visual stimulus enhances subsequent auditory perception.

A survey of patient perspectives on the research use of health information and biospecimens.

Background: Personal health information and biospecimens are valuable research resources essential for the advancement of medicine and protected by national standards and provincial statutes. Research ethics and privacy standards attempt to balance individual interests with societal interests. However these standards may not reflect public opinion or preferences.

Causes of death among an urban homeless population considered by the medical examiner.

Those who are homeless face illness and death, however, live in places not conducive to provision of end-of-life care. Limited information exists on causes of death among this group of people. To characterize causes of death, data were requested from the Office of the Chief Medical Examiner for Alberta Justice, Canada, for people determined to be homeless in the period 2007-2009.

Measurement of the parity-violating asymmetry in inclusive electroproduction of π- near the Δ0 resonance.

The parity-violating (PV) asymmetry of inclusive π- production in electron scattering from a liquid deuterium target was measured at backward angles. The measurement was conducted as a part of the G0 experiment, at a beam energy of 360 MeV. The physics process dominating pion production for these kinematics is quasifree photoproduction off the neutron via the Δ0 resonance.

A descriptive study of chiropractors' opinions and practices regarding office-based health product sales.

Background: Although the sale of non-prescription health products is ubiquitous, the views of health professionals, such as chiropractors, regarding the sale of such products are not well known. Practitioner opinion is important to understand and inform professional practice. The purpose of this study was to describe chiropractors' perspectives and practices on the sale of health care products from practitioners' offices.

Dynamics of walking adaptation aftereffects induced in static images of walking actors.

Visual adaptation to walking actions results in subsequent aftereffects that bias perception of static images of walkers in different postures so that they are interpreted as walking in the opposite direction to the adapting actor. It is not clear, however, if the walking aftereffect is comparable to other well studied low- and high-level visual aftereffects. We therefore measured the dynamics of the walking aftereffect in order to assess the characteristics of the adapting mechanism.
