REVIEW
Christopher J Tape
Tissues contain multiple different cell types and can be considered to be heterocellular systems. Signaling between different cells allows tissues to achieve phenotypes that no cell type can achieve in isolation. Such emergent tissue-level phenotypes can be said to 'supervene upon' heterocellular signaling. It is proposed here that cancer is also an emergent phenotype that supervenes upon heterocellular signaling. Using colorectal cancer (CRC) as an example, I review how heterotypic cells differentially communicate to support emergent malignancy...

The envelope (Env) of Jaagsiekte sheep retrovirus (JSRV) is an oncoprotein of ovine pulmonary adenocarcinoma (OPA). Autophagy is involved in different cancers, but how it is carcinogenic in JSRV Env is unclear. Modulation of autophagy in exJSRV-env-NM-transfected cells through the Akt/mTOR and MAPK signaling pathway was studied, and we observed strong positive labeling of p-Akt, p-mTOR, p-MEK1/2, p-ERK1/2, p-p38 and p-JNK in tumor cells and typical type II pneumocytes in naturally infected OPA lung tissues, which was co-aligned with JSRV-Env positive cells as shown by immunohistochemical and microscopic analysis...

The signaling of reactive oxygen species (ROS) is essential for the maintenance of normal cellular function. However, whether and how ROS regulate stem cells are unclear. Here, we demonstrate that, in transgenic mice expressing the human manganese superoxide dismutase (MnSOD) gene, a scavenger of ROS in mitochondria, the number and function of mouse hematopoietic stem/progenitor cells (HSPC) under physiological conditions are enhanced. Importantly, giving MnTnBuOE-2-PyP(5+)(MnP), a redox- active MnSOD mimetic, to mouse primary bone marrow cells or to C57B/L6 mice significantly enhances the number of HSPCs...

OBJECTIVES: Traumatic spinopelvic dissociation separates the spinal column from the pelvis, which usually creates lumbosacral kyphosis. We aimed to examine how the spinopelvic profiles changes after traumatic spinopelvic dissociation, and which are the relevant factors for the sagittal imbalance of the spine. DESIGN: Retrospective analysis. SETTING: Level I trauma center PATIENTS:: Thirty-nine consecutive patients who were diagnosed with traumatic spinopelvic dissociation and had a minimum 2-year radiological follow-up were included...

A robotic exoskeleton was designed for individuals with crouch gait caused by cerebral palsy with the intent to supplement existing muscle function during walking. The aim of this study was to evaluate how powered knee extension assistance provided during stance and swing phases of the gait cycle affect knee kinematics, and knee flexor and extensor muscle activity. Muscle activity and kinematic data were collected from four individuals with crouch gait from cerebral palsy during their normal walking condition and while walking with the exoskeleton under stance, swing, and stance & swing assistance...

State-of-the-art hearing prostheses are equipped with acoustic noise reduction algorithms to improve speech intelligibility. Currently, one of the major challenges is to perform acoustic noise reduction in so-called cocktail party scenarios with multiple speakers, in particular because it is difficult-if not impossible-for the algorithm to determine which are the target speaker(s) that should be enhanced, and which speaker(s) should be treated as interfering sources. Recently, it has been shown that electroencephalography (EEG) can be used to perform auditory attention detection, i...

Reclaimed water (i.e., reused advanced-treated wastewater) offers an alternative water resource. To reduce the health risks associated with its use, efficient virus removal such as with advanced wastewater treatment processes is important. Virus removal by coagulation followed by ultrafiltration (UF) for the treatment of drinking water has been well examined. But its efficacy in wastewater reclamation purpose using secondary treated effluent (SE) from wastewater treatment plant (WWTP) as feed water is unclear...

This is an exciting time for immunology because the future promises to be replete with exciting new discoveries that can be translated to improve health and treat disease in novel ways. Immunologists are attempting to answer increasingly complex questions concerning phenomena that range from the genetic, molecular, and cellular scales to that of organs, whole animals or humans, and populations of humans and pathogens. An important goal is to understand how the many different components involved interact with each other within and across these scales for immune responses to emerge, and how aberrant regulation of these processes causes disease...

Objective: To determine how pre-stroke cognitive impairment can be detected, its mechanism, and influence on outcome and management. Methods: Literature search. Results: (i) A systematic approach with the Informant Questionnaire of Cognitive Decline in the Elderly is recommended; (ii) Pre-stroke cognitive impairment may be due to brain lesions of vascular, degenerative, or mixed origin; (iii) Patients with pre-stroke dementia, have worse outcomes, more seizures, delirium, and depression, and higher mortality rates; they often need to be institutionalised after their stroke; (iv) Although the safety profile of treatment is not as good as that of cognitively normal patients, the risk:benefit ratio is in favour of treating these patients like others...

Studies employing the Ultimatum Game (UG) which involves two parties (i.e., proposers and responders) splitting some money have suggested the role that anterior insula (AI) plays in detecting fairness norm violation, i.e., violation of the responder's expectation of receiving equal splits from the proposer. In this study, we explored how AI would respond when there existed simultaneously another expectation of being treated equivalently as others. Participants acted as responders and would be informed about both the offers they received and the average amount of money the same proposer offered to others...

BACKGROUND: Although the prognosis of localised prostate cancer is good, the negative effects of prostate cancer treatment often impair patient quality of life. A growing number of men experience these negative effects over a longer time because of the increased incidence of and prolonged survival in prostate cancer, and the ageing of the population. Only a few studies have investigated the adverse effects of different prostate cancer treatments using large population-based samples. METHODS: We conducted a nationwide survey (n=1239) to collect detailed information regarding the negative effects (i...

Prostate cancer (PC) treatment side-effects such as erectile dysfunction (ED) can impact men's quality of life (QoL), psychosocial and psycho-sexual adjustment. Masculinity (i.e., men's identity or sense of themselves as being a man) may also be linked to how men respond to PC treatment and ED however the exact nature of this link is unclear. This review aims to provide a snapshot of the current state of evidence regarding ED, masculinity and psychosocial impacts after PC treatment. Three databases (Medline/PsycINFO, CINHAL, and EMBASE) were searched January 1st 1980 to January 31st 2016...

There is growing evidence that Aboriginal peoples often experience healthcare inequalities due to racism. However, research exploring the healthcare experiences of Aboriginal peoples who use illicit substances is limited, and research rarely accounts for how multiple accounts of stigma intersect and contribute to the experiences of marginalized populations. Our research aimed to explore the healthcare experiences of Aboriginal peoples who use illicit drugs and or illicit alcohol (APWUID/A) living in Vancouver's inner city...

Managing individuals with chronic disorders of consciousness raises ethical questions about the appropriateness of maintaining life-sustaining treatments and end-of-life decisions for those who are unable to make decisions for themselves. For many years, the positions fostering the "sanctity" of human life (i.e., life is inviolable in any case) have led to maintaining life-sustaining treatments (including artificial nutrition and hydration) in patients with disorders of consciousness, allowing them to live for as long as possible...

Accumulation of the interferon-stimulated gene (ISG) 15 protein product, which is reversibly conjugated to numerous polypeptide targets, impacts the proteome and physiology of uninfected and infected cells. While many viruses, including human cytomegalovirus (HCMV) blunt host antiviral defenses by limiting ISG expression, the overall abundance of ISG15 monomer and protein conjugates rises in HCMV-infected cells. However, the molecular signals underlying ISG15 accumulation and whether the ISG15 polypeptide itself influences HCMV infection biology remain unknown...

INTRODUCTION: Patients consulting for sexual difficulties frequently present additional personal or relational disorders and symptoms. This is especially the case when they have experienced cumulative adverse childhood experiences (CACEs), which are associated with symptom complexity. CACEs refer to the extent to which an individual has experienced an accumulation of different types of adverse childhood experiences including sexual, physical, and psychological abuse; neglect; exposure to inter-parental violence; and bullying...

BACKGROUND: When used as an adjunctive with antipsychotics, certain vitamins and minerals may be effective for improving symptomatic outcomes of schizophrenia, by restoring nutritional deficits, reducing oxidative stress, or modulating neurological pathways. METHOD: We conducted a systematic review of all randomized controlled trials (RCTs) reporting effects of vitamin and/or mineral supplements on psychiatric symptoms in people with schizophrenia. Random-effects meta-analyses were used to calculate the standardized mean difference between nutrient and placebo treatments...
