Patient organization perspective: a research roadmap for Okur-Chung Neurodevelopmental Syndrome.

Okur-Chung neurodevelopmental syndrome (OCNDS) is an ultra-rare disorder caused by variants in the gene. encodes for the alpha subunit of casein kinase 2 (CK2), a serine/threonine kinase critical in neural development. CK2 is implicated in many human pathologies, including viral infections, cancer, inflammation, cardiovascular, neurodegenerative, and psychiatric diseases.

F@#$ pain! A mini-review of the hypoalgesic effects of swearing.

Swearing, or the use of taboo language, has been repeatedly shown to induce hypoalgesia. While reliable hypoalgesic effects have been observed across studies, the mechanisms by which swearing influences pain and the optimal dosage of swearing remain poorly understood. Plausible mechanistic rationale for swearing's impact on pain include sympathetic response, emotion, humor, distraction, aggression, state disinhibition, psychological flow, risky behavior, and self-confidence.

Nonlinear progression during the occult transition establishes cancer lethality.

Cancer screening is based upon a linear model of neoplastic growth and malignant progression. Yet, historical observations suggest that malignant progression is uncoupled from growth which may explain the paradoxical increase in early-stage breast cancer detection without a dramatic reduction in metastatic burden. Here we lineage trace millions of genetically transformed field cells and thousands of screen detectable and symptomatic tumors using a cancer rainbow mouse model of HER2+ breast cancer.

Auditory masking in odobenid and otariid carnivoresa).

As the only living species within the odobenid lineage of carnivores, walruses (Odobenus rosmarus) have no close relatives from which auditory information can be extrapolated. Sea lions and fur seals in the otariid lineage are the nearest evolutionary outgroup. To advance understanding of odobenid and otariid hearing, we conducted behavioral testing with two walruses and one California sea lion (Zalophus californianus).

Mechanisms of auditory masking in marine mammals.

Anthropogenic noise is an increasing threat to marine mammals that rely on sound for communication, navigation, detecting prey and predators, and finding mates. Auditory masking is one consequence of anthropogenic noise, the study of which is approached from multiple disciplines including field investigations of animal behavior, noise characterization from in-situ recordings, computational modeling of communication space, and hearing experiments conducted in the laboratory. This paper focuses on laboratory hearing experiments applying psychophysical methods, with an emphasis on the mechanisms that govern auditory masking.

Reciprocal associations of perceived discrimination, internalizing symptoms, and academic achievement in Latino students across the college transition.

Objective: Despite growing evidence that perceived discrimination negatively impacts underrepresented ethnic-racial college students, there is a lack of longitudinal studies with multiple sources of discrimination as Latinos transition from high school (HS) to college. This study examined changes in peer, adult, and everyday discrimination across the college transition and tested concurrent, prospective, and reciprocal associations between these sources of discrimination, internalizing symptoms, and grade point average (GPA).

Method: Latino adolescents ( = 209; at Time 1 = 18.

In her own words: understanding the health needs of older lesbians.

This project illuminates the unique struggles and barriers lesbians face. A community advisory board (CAB) was developed and 31 in-depth interviews were conducted with lesbians aged 56-84 in the Rocky Mountain region. Interviews were audio recorded, transcribed, and coded using critical discourse analysis.

In-air hearing in Hawaiian monk seals: implications for understanding the auditory biology of Monachinae seals.

The auditory biology of Monachinae seals is poorly understood. Limited audiometric data and certain anatomical features suggest that these seals may have reduced sensitivity to airborne sounds compared to related species. Here, we describe the in-air hearing abilities of a Hawaiian monk seal (Neomonachus schauinslandi) trained to participate in a psychophysical paradigm.

Evaluating temporary threshold shift onset levels for impulsive noise in seals.

The auditory effects of single- and multiple-shot impulsive noise exposures were evaluated in a bearded seal (Erignathus barbatus). This study replicated and expanded upon recent work with related species [Reichmuth, Ghoul, Sills, Rouse, and Southall (2016). J.

Long-term evidence of noise-induced permanent threshold shift in a harbor seal (Phoca vitulina).

In psychophysical studies of noise-induced hearing loss with marine mammals, exposure conditions are often titrated from levels of no effect to those that induce significant but recoverable loss of auditory sensitivity [temporary threshold shift (TTS)]. To examine TTS from mid-frequency noise, a harbor seal was exposed to a 4.1-kHz underwater tone that was incrementally increased in sound pressure level (SPL) and duration.

Active touch in sea otters: in-air and underwater texture discrimination thresholds and behavioral strategies for paws and vibrissae.

Sea otters () are marine predators that forage on a wide array of cryptic, benthic invertebrates. Observational studies and anatomical investigations of the sea otter somatosensory cortex suggest that touch is an important sense for detecting and capturing prey. Sea otters have two well-developed tactile structures: front paws and facial vibrissae.

The influence of temporally varying noise from seismic air guns on the detection of underwater sounds by seals.

Standard audiometric data are often applied to predict how noise influences hearing. With regard to auditory masking, critical ratios-obtained using tonal signals and flat-spectrum maskers-can be combined with noise spectral density levels derived from 1/3-octave band levels to predict signal amplitudes required for detection. However, the efficacy of this conventional model of masking may vary based on features of the signal and noise in question.

Testing the Efficacy of DNA Barcodes for Identifying the Vascular Plants of Canada.

Their relatively slow rates of molecular evolution, as well as frequent exposure to hybridization and introgression, often make it difficult to discriminate species of vascular plants with the standard barcode markers (rbcL, matK, ITS2). Previous studies have examined these constraints in narrow geographic or taxonomic contexts, but the present investigation expands analysis to consider the performance of these gene regions in discriminating the species in local floras at sites across Canada. To test identification success, we employed a DNA barcode reference library with sequence records for 96% of the 5108 vascular plant species known from Canada, but coverage varied from 94% for rbcL to 60% for ITS2 and 39% for matK.

Low-frequency temporary threshold shift not observed in spotted or ringed seals exposed to single air gun impulses.

Underwater hearing thresholds were measured at 100 Hz in trained spotted (Phoca largha) and ringed seals (Pusa hispida) before and immediately following voluntary exposure to impulsive noise from a seismic air gun. Auditory responses were determined from psychoacoustic data and behavioral responses were scored from video recordings. Four successive exposure conditions of increasing level were tested, with received unweighted sound exposure levels from 165 to 181 dB re 1 μPa s and peak-to-peak sound pressures from 190 to 207 dB re 1 μPa.

Effects of compassion meditation on a psychological model of charitable donation.

Compassion is critical for societal wellbeing. Yet, it remains unclear how specific thoughts and feelings motivate compassionate behavior, and we lack a scientific understanding of how to effectively cultivate compassion. Here, we conducted 2 studies designed to a) develop a psychological model predicting compassionate behavior, and b) test this model as a mediator of a Compassion Meditation (CM) intervention and identify the "active ingredients" of CM.

The role of collaboration in the cognitive development of young children: a systematic review.

Background: Collaboration is a key facilitator of cognitive development in early childhood; this review evaluates which factors mediate the impact of collaborative interactions on cognitive development in children aged 4-7 years.

Methods: A systematic search strategy identified relevant studies (n = 21), which assessed the role of ability on the relationship between collaboration and cognitive development. Other factors that interact with ability were also assessed: gender, sociability/friendship, discussion, age, feedback and structure.

An evaluation of the benefits to a UK Health Care Trust working in a partnership with a hospital in Northern Uganda: International partnership working in mental health.

Background: Despite the worthy intentions of international health partnerships between high-income countries and countries with developing economies, the tangible benefits are rarely evaluated, limiting the assessment of the achievements of such collaborations.

Methods: The present study used longitudinal qualitative methods to examine the individual and organisational benefits of a partnership between a National Health Service (NHS) mental health Trust in the United Kingdom and a mental health referral hospital in Northern Uganda. Benefits to UK staff and organisational development were benchmarked against an existing framework of healthcare competencies.

Amphibious hearing in ringed seals (Pusa hispida): underwater audiograms, aerial audiograms and critical ratio measurements.

Ringed seals (Pusa hispida) are semi-aquatic marine mammals with a circumpolar Arctic distribution. In this study, we investigate the amphibious hearing capabilities of ringed seals to provide auditory profiles for this species across the full range of hearing. Using psychophysical methods with two trained ringed seals, detection thresholds for narrowband signals were measured under quiet, carefully controlled environmental conditions to generate aerial and underwater audiograms.

Amphibious hearing in spotted seals (Phoca largha): underwater audiograms, aerial audiograms and critical ratio measurements.

Spotted seals (Phoca largha) inhabit Arctic regions that are facing both rapid climate change and increasing industrialization. While little is known about their sensory capabilities, available knowledge suggests that spotted seals and other ice seals use sound to obtain information from the surrounding environment. To quantitatively assess their auditory capabilities, the hearing of two young spotted seals was tested using a psychophysical paradigm.

Comparative assessment of amphibious hearing in pinnipeds.

Auditory sensitivity in pinnipeds is influenced by the need to balance efficient sound detection in two vastly different physical environments. Previous comparisons between aerial and underwater hearing capabilities have considered media-dependent differences relative to auditory anatomy, acoustic communication, ecology, and amphibious life history. New data for several species, including recently published audiograms and previously unreported measurements obtained in quiet conditions, necessitate a re-evaluation of amphibious hearing in pinnipeds.

Hope and cardiovascular health-promoting behaviour: education alone is not enough.

We investigated hope's ability to predict cardiovascular disease (CVD) knowledge and health-promoting behaviours. Snyder defined hope as the combination of goal-directed planning and motivation, and theorised that high-hope people seek knowledge relevant to goal pursuits. We surveyed 391 Latino and Asian participants undergoing CVD risk screening, nearly all immigrants to the USA.
