Development and Use of Mobile Messaging for Individuals With Musculoskeletal Pain Conditions: Scoping Review.

Background: Population studies show that musculoskeletal conditions are a leading contributor to the total burden of healthy life lost, second only to cancer and with a similar burden to cardiovascular disease. Prioritizing the delivery of effective treatments is necessary, and with the ubiquity of consumer smart devices, the use of digital health interventions is increasing. Messaging is popular and easy to use and has been studied for a range of health-related uses, including health promotion, encouragement of behavior change, and monitoring of disease progression.

Cueing involuntary memory.

We raise two points about cues, which complicate Barzykowski and Moulin's attempt at a unified model of memory retrieval. First, cues operate differently in voluntary and involuntary contexts. Second, voluntary and involuntary memory can be interconnected, as in cases of chaining.

Implementation of a risk-stratified, guideline-based clinical pathway of care to improve health outcomes following whiplash injury (Whiplash ImPaCT): a multicentre, randomized, controlled trial.

Current pathways of care for whiplash follow a "stepped care model," result in modest treatment outcomes and fail to offer efficient management solutions. This study aimed to evaluate the effectiveness of a risk-stratified clinical pathway of care (CPC) compared with usual care (UC) in people with acute whiplash. We conducted a multicentre, 2-arm, parallel, randomised, controlled trial in primary care in Australia.

The 21st century engram.

The search for the engram-the neural mechanism of memory-has been a guiding research project for neuroscience since its emergence as a distinct scientific field. Recent developments in the tools and techniques available for investigating the mechanisms of memory have allowed researchers to proclaimed the search is over. While there is ongoing debate about the justification for that claim, renewed interest in the engram is clear.

Loss of Function of the Neural Cell Adhesion Molecule NrCAM Regulates Differentiation, Proliferation and Neurogenesis in Early Postnatal Hypothalamic Tanycytes.

Hypothalamic tanycytes are neural stem and progenitor cells, but little is known of how they are regulated. Here we provide evidence that the cell adhesion molecule, NrCAM, regulates tanycytes in the adult niche. NrCAM is strongly expressed in adult mouse tanycytes.

Development and use of mobile messaging for individuals with musculoskeletal pain conditions: a scoping review protocol.

Introduction: Previous reviews of mobile messaging for individuals with musculoskeletal pain have shown positive effects on pain and disability. However, the configuration of digital content, method of presentation and interaction, dose and frequency needed for optimal results remain unclear. Patient preferences concerning such systems are also unclear.

Leptin receptor-expressing pericytes mediate access of hypothalamic feeding centers to circulating leptin.

Knowledge of how leptin receptor (LepR) neurons of the mediobasal hypothalamus (MBH) access circulating leptin is still rudimentary. Employing intravital microscopy, we found that almost half of the blood-vessel-enwrapping pericytes in the MBH express LepR. Selective disruption of pericytic LepR led to increased food intake, increased fat mass, and loss of leptin-dependent signaling in nearby LepR neurons.

NG2-Glia, a New Player in Energy Balance.

There is increasing evidence that glia act not only as neuronal support cells, but that they can also influence physiological outcomes via effects on neural signalling. The role of NG2-glia in this regard is especially enigmatic, as they are known to interact with neural circuits but their precise functions other than as oligodendrocyte progenitor cells remain elusive. Here, we summarise recent evidence suggesting that NG2-glia play a role in the maintenance of energy homeostasis, most notably via the support of leptin-sensing neural circuits.

Confabulation and epistemic authority.

Mahr & Csibra (M&C) claim that episodic remembering's autonoetic character serves as an indicator of epistemic authority. This proposal is difficult to reconcile with the existence of confabulation errors - where participants fabricate memories of experiences that never happened to them. Making confabulation errors damages one's epistemic authority, but these false memories have an autonoetic character.

Parent-child conversations about literacy: a longitudinal, observational study.

Conversations about literacy-related matters with parents can help prepare children for formal literacy instruction. We studied these conversations using data gathered from fifty-six US families as they engaged in daily activities at home. Analyzing conversations when children were aged 1;10, 2;6, 3;6, and 4;2, we found that explicit talk about the elements and processes of reading and writing occurred even when children were less than two years old and became more common as children grew older.

Adult NG2-Glia Are Required for Median Eminence-Mediated Leptin Sensing and Body Weight Control.

While leptin is a well-known regulator of body fat mass, it remains unclear how circulating leptin is sensed centrally to maintain energy homeostasis. Here we show that genetic and pharmacological ablation of adult NG2-glia (also known as oligodendrocyte precursors), but not microglia, leads to primary leptin resistance and obesity in mice. We reveal that NG2-glia contact the dendritic processes of arcuate nucleus leptin receptor (LepR) neurons in the median eminence (ME) and that these processes degenerate upon NG2-glia elimination, which explains the consequential attenuation of these neurons' molecular and electrical responses to leptin.

Parents' Talk About Letters With Their Young Children.

A literacy-related activity that occurs in children's homes-talk about letters in everyday conversations-was examined using data from 50 children who were visited every 4 months between 14 and 50 months. Parents talked about some letters, including those that are common in English words and the first letter of their children's names, especially often. Parents' focus on the child's initial was especially strong in families of higher socioeconomic status, and the extent to which parents talked about the child's initial during the later sessions of the study was related to the children's kindergarten reading skill.

Letter Knowledge in Parent-Child Conversations.

Learning about letters is an important component of emergent literacy. We explored the possibility that parent speech provides information about letters, and also that children's speech reflects their own letter knowledge. By studying conversations transcribed in CHILDES (MacWhinney, 2000) between parents and children aged one to five, we found that alphabetic order influenced use of individual letters and letter sequences.

Letter knowledge in parent-child conversations: differences between families differing in socio-economic status.

When formal literacy instruction begins, around the age of 5 or 6, children from families low in socioeconomic status (SES) tend to be less prepared than children from families of higher SES. The goal of our study is to explore one route through which SES may influence children's early literacy skills: informal conversations about letters. The study builds on previous studies (Robins and Treiman, 2009; Robins et al.

Evidence for NG2-glia derived, adult-born functional neurons in the hypothalamus.

Accumulating evidence suggests that the adult murine hypothalamus, a control site of several fundamental homeostatic processes, has neurogenic capacity. Correspondingly, the adult hypothalamus exhibits considerable cell proliferation that is ongoing even in the absence of external stimuli, and some of the newborn cells have been shown to mature into cells that express neuronal fate markers. However, the identity and characteristics of proliferating cells within the hypothalamic parenchyma have yet to be thoroughly investigated.

Extensive regenerative plasticity among adult NG2-glia populations is exclusively based on self-renewal.

NG2-glia are known to proliferate in the adult brain, however the extent of their mitotic and regenerative capacity and particularly their adult origin is uncertain. By employing a paradigm of mitotic blockade in conjunction with genetic fate tracing we demonstrate that intracerebroventricular mitotic blocker infusion leads to wide-spread and complete ablation of NG2-glial cells in the hypothalamus and other periventricular brain regions. However, despite the extensive glia loss, parenchymal NG2-glia coverage is fully restored to pretreatment levels within two weeks.

Parent-Child Conversations About Letters and Pictures.

Learning about letters, and how they differ from pictures, is one important aspect of a young child's print awareness. To test the hypothesis that parent speech provides children with information about these differences, we studied parent-child conversations in CHILDES (MacWhinney, 2000). We found that parents talk to their young children about letters, differentiating them from pictures, by 1-2 years of age and that some of these conversational patterns change across the preschool years in ways that emphasize important features of letters, such as their shape.

The mating sociometer: a regulatory mechanism for mating aspirations.

Two studies (Ns = 80 and 108) tested hypotheses derived from Kirkpatrick and Ellis's (2001) extension and application of sociometer theory to mating aspirations. Experiences of social rejection-acceptance by attractive opposite-sex confederates were experimentally manipulated, and the impact of these manipulations on self-esteem, mating aspirations, and friendship aspirations was assessed. Results indicated that social rejection-acceptance by members of the opposite sex altered mating aspirations; that the causal link between social rejection-acceptance and mating aspirations was mediated by changes in state self-esteem; and that the impact of social rejection-acceptance by members of opposite sex was specific to mating aspirations and did not generalize to levels of aspiration in approaching potential same-sex friendships.

Talking About Writing: What We Can Learn from Conversations between Parents and Their Young Children.

In six analyses using CHILDES (MacWhinney, 2000), we explored whether and how parents and their 1.5 to 5-year-old children talk about writing. Parent speech might include information about the similarity between print and speech and about the difference between writing and drawing.
