The robust steady-state cortical activation elicited by flickering visual stimulation has been exploited by a wide range of scientific studies. As the fundamental neural response inherits the spectral properties of the gazed flickering, the paradigm has been used to chart cortical characteristics and their relation to pathologies. However, despite its widespread adoption, the underlying neural mechanisms are not well understood. #link# Here, we show that the fundamental response is preceded by high-gamma (55-125 Hz) oscillations which are also synchronised to the gazed frequency. Using a subdural recording of the primary and associative visual cortices of one human subject, we demonstrate that the latencies of the high-gamma and fundamental components are highly correlated on a single-trial basis albeit that the latter is consistently delayed by approximately 55 ms. These results corroborate previous reports that top-down feedback projections are involved in the generation of the fundamental response, but, in addition, we show that trial-to-trial variability in fundamental latency is paralleled by a highly similar variability in high-gamma latency. Pathology- or paradigm-induced alterations in steady-state responses could thus originate either from deviating visual gamma responses or from aberrations in the neural feedback mechanism. Experiments designed to tease apart the two processes are expected to provide deeper insights into the studied paradigm.Climate warming is rapidly reshaping the Arctic cryosphere and ocean conditions, with consequences for sea ice and pelagic productivity patterns affecting the entire marine food web. To predict how click here will impact Arctic marine ecosystems, concerted effort from various disciplines is required. Here, we contribute multi-decadal reconstructions of changes in diatom production and sea-ice conditions in relation to Holocene climate and ocean conditions off northwest Greenland. Our multiproxy study includes diatoms, sea-ice biomarkers (IP25 and HBI III) and geochemical tracers (TOC [total organic carbon], TOCTN [total nitrogen], δ13 C, δ15 N) from a sediment core record spanning the last c. 9,000 years. Our results suggest that the balance between the outflow of polar water from the Arctic, and input of Atlantic water from the Irminger Current into the West Greenland Current is a key factor in controlling sea-ice conditions, and both diatom phenology and production in northeastern Baffin Bay. Our proxy record notably shows that changes in sea-surface conditions initially forced by Neoglacial cooling were dynamically amplified by the shift in the dominant phase of the Arctic Oscillation (AO) mode that occurred at c. 3,000 yr BP, and caused drastic changes in community composition and a decline in diatom production at the study site. In the future, with projected dominant-positive AO conditions favored by Arctic warming, increased water column stratification may counteract the positive effect of a longer open-water growth season and negatively impact diatom production.
We describe the landscape of cyclin and interactive gene pathway alterations in 190,247 solid tumors.

Using comprehensive genomic profiling (315 genes, >500× coverage), samples were analyzed for alterations in activating/sensitizing cyclin genes (CDK4 amplification, CDK6 amplification, CCND1, CCND2, CCND3, CDKN2B [loss], CDKN2A [loss], SMARCB1), hormone genes (estrogen receptor 1 [ESR1], androgen receptor [AR]), and co-alterations in genes leading to cyclin inhibitor therapeutic resistance (RB1 and CCNE1).

Alterations in at least one cyclin activating/sensitizing gene occurred in 24% of malignancies. Tumors that frequently harbored at least one cyclin alteration were brain gliomas (47.1%), esophageal (40.3%) and bladder cancer (37.9%), and mesotheliomas (37.9%). The most frequent alterations included CDKN2A (13.9%) and CDKN2B loss (12.5%). Examples of unique patterns of alterations included CCND1 amplification in breast cancer (17.3%); CDK4 alterations in sarcomas (12%); CCND2 in testicular cancer (2an solid tumors, with substantial variation according to tumor site and histology. Opportunities for targeted therapy emerge with comprehensive profiling of this pathway.

Depression is a common disorder in old age and increases with hospitalisation. The aim was to investigate whether improvement in depressive symptoms after hospitalisation is associated with education level, age, gender, living situation, self-efficacy, activities in daily living and quality of life by (1) examining the prevalence of depressive symptoms at baseline and at 1st and 2nd follow-up (2) examining different factors' association with depressive symptoms at baseline and (3) examining different factors' association with improvement in depressive symptoms at baseline and at 1st and 2nd follow-up.

The study consisted of 145 patients, 65years and older. Data were collected between February 2015 and September 2016 through interviews conducted using structured protocols. The instrument used was Katz index of ADL, Geriatric Depression Scale-20, Life Satisfaction Questionnaire and the General Self-Efficacy Scale. The participants were interviewed before discharge from hospital, after 1.5month and after 3mo need and a possibility to help them in an appropriate manner. Persons with lower educational level and depressive symptoms need special attention.
To analyze the association between body mass index trajectories and non-communicable diseases (NCDs) in women, and the interaction effects of leisure time physical activity on this relationship.

Sample was composed by 15 628 women (≥30 years old) who performed objective measurement of body mass, height, and blood pressure in the 2013 Brazilian Health Survey (2013). Information regarding the body mass at 20 years old, current type 2 diabetes (T2DM), dyslipidemia diagnosis, and leisure time physical activity were self-reported by the participants. Socio-demographic and behavioral covariates were considered. Logistic regression models were used for the statistical analysis.

Those who were obese in both moments and women who become obese showed similar high risk, however, the prevalence of NCDs among women who were no longer obese was similar to the consistently non-obese. Leisure time physical activity attenuated the general deleterious effect of obesity, especially among the consistently obese women for dyslipidemia (inactive OR 2.02 [95%CI 1.69-2.43] vs active OR 1.05 [95%CI 0.55-1.99]), T2DM (inactive OR 3.84 [95%CI 2.72-5.43] vs active OR 4.38 [95%CI 1.49-12.86]) and high blood pressure (inactive OR 2.00 [95%CI 1.56-2.57] vs active OR 1.15 [95%CI 0.57-2.52]).

Changes in body mass index appear to be sensitive to detecting the risk of NCDs over lifespan. In addition, leisure time physical activity attenuates the negative effects of obesity on NCDs, but this appears more important for the consistently non-obese women.

Food literacy programs aim to improve an individual's knowledge and skills in the planning, management, selection, preparation and eating of healthy foods. Unhealthy dietary patterns across the life cycle are associated with an increased risk of chronic disease. Foodbank WA's Healthy Food for All
(HFFA) team has made addressing health inequity a priority, by enhancing food literacy skills of vulnerable people across the lifespan.

A case study approach was utilised to explore HFFA's suite of evidence-based food literacy programs Food Sensations
(FS) for Parents (of 0-5year olds), FS for Schools (kindergarten to Year 12), Fuel Your Future (adolescents 12-18years), and FS for Adults (FSA) (18years and over). These programs are contextualised to meet the needs of vulnerable groups at all life stages.

In the last decade the HFFA team have delivered 5047 food literacy sessions to over 62000 vulnerable Western Australians. Evaluation results demonstrate the FS programs are successful at improving vulnerablent in food literacy initiatives is vital to improving the health outcomes of vulnerable populations.Bacterial microcompartments are protein-based organelles that carry out specialized metabolic functions in diverse bacteria. Their outer shells are built from several thousand protein subunits. Some of the architectural principles of bacterial microcompartments have been articulated, with lateral packing of flat hexameric BMC proteins providing the basic foundation for assembly. Nonetheless, a complete understanding has been elusive, partly owing to polymorphic mechanisms of assembly exhibited by most microcompartment types. An earlier study of one homologous BMC shell protein subfamily, EutS/PduU, revealed a profoundly bent, rather than flat, hexameric structure. The possibility of a specialized architectural role was hypothesized, but artifactual effects of crystallization could not be ruled out. Here we report a series of crystal structures of an orthologous protein, CutR, from a glycyl-radical type choline-utilizing microcompartment from the bacterium Streptococcus intermedius. link3 Depending on crystal form, expression construct, and minor mutations, a range of novel quaternary architectures was observed, including two spiral hexagonal assemblies. A new graphical approach helps illuminate the variations in BMC hexameric structure, with results substantiating the idea that the EutS/PduU/CutR subfamily of BMC proteins may endow microcompartment shells with flexible modes of assembly.Alcohol use disorder (AUD) is associated with changes in frontostriatal connectivity, but functional magnetic resonance imaging (fMRI) functional connectivity (FC) approaches are usually not adapted to these circuits. We developed a circuit-specific fMRI analysis approach to detect dynamic changes in frontostriatal FC inspired by medial-ventral-rostral to lateral-dorsal-caudal frontostriatal gradients originally identified in nonhuman primate tract-tracing data. In our PeaCoG ("peak connectivity on a gradient") approach we use information about the location of strongest FC on empirical frontostriatal connectivity gradients. We have recently described a basic PeaCoG version with conventional FC, and now developed a dynamic PeaCoG approach with sliding-window FC. In resting state data of n = 66 AUD participants and n = 40 healthy controls we continue here the analyses that we began with the basic version. Our former result of an AUD-associated ventral shift in right orbitofrontal cortex PeaCoG is consistently detected in the dynamic approach. Temporospatial variability of dynamic PeaCoG in the left dorsolateral prefrontal cortex is reduced in AUD and associated with self-efficacy to abstain and days of abstinence. Our method has the potential to provide insight into the dynamics of frontostriatal circuits, which has so far been relatively unexplored, and into their role in mental disorders and normal cognition.
