Assessment domain of existing and emerging Low trophic species aquaculture activities around the Atlantic
<p>The Assessment domain was constructed from a set of characteristics (main aspects/categories, e.g., organism group or production system), each consisting of several pre-determined elements (sub-categories, e.g., bivalves, brown macroalgae or surface systems, bottom culture systems) describing the activities, with each unique combination of characteristics (i.e., of one element per characteristic) resulting in the description of one type of LTS-system. The total of all possible LTS-systems constitutes the domain, providing the boundaries and resolution for the work to come.</p> <p>In this data set, the results from the mapping of existing and emerging LTS aquaculture activities around the Atlantic is reported and summarised. The results are related to FAO production statistics and analysed in terms of recommendations for the WP6 activities. In more general terms, the report may also act as a baseline to explore regional differences in LTS aquaculture diversity as well as diversification of LTS activities over time in the region.</p>

Data from: Olfactory modulation of barrel cortex activity during active whisking and passive whisker stimulation
<p>Rodents depend on olfaction and touch to meet many of their fundamental needs. The joint significance of these sensory systems is underscored by an intricate coupling between sniffing and whisking. However, the impact of simultaneous olfactory and tactile inputs on sensory representations in the cortex remains elusive. To study these interactions, we recorded large populations of barrel cortex neurons using 2-photon calcium imaging in head-fixed mice during olfactory and tactile stimulation. We find that odors alter barrel cortex activity in at least two ways, first by enhancing whisking, and second by central cross-talk that persists after whisking is abolished by facial nerve sectioning. Odors can either enhance or suppress barrel cortex neuronal responses, and while odor identity can be decoded from population activity, it does not interfere with the tactile representation. Thus, barrel cortex represents olfactory information which, in the absence of learned associations, is coded independently of tactile information.</p>

Insecticidal activity of Beauveria bassiana against Monochamus alternatus adults
<p><em><span>Monochamus alternatus</span></em><span> is a major forest pest that spreads pine wilt disease in pine trees as a vector of pine wilt nematodes. Chemical insecticides used as fumigants to control overwintering <em>M. alternatus</em> in forests are highly toxic to the environment, so we investigated entomopathogenic fungus <em>Beauveria bassiana</em> ERL836 as an eco-friendly and alternative material to control overwintering <em>M. alternatus</em>. In this work, we evaluated the insecticidal activity of <em>B. bassiana</em> ERL836 against <em>M. alternatus</em> adults, the possibility of fungal colonization on pine tree bark, and finally the control efficacy of fungal pre-treatment on pine tree logs against emerging M. alternatus adults in semi-field and field conditions. <em>M. alternatus</em> adults were killed on the pine trees logs pre-treated with the <em>B. bassiana</em> ERL836. White conidia were observed not only on the surface of the dead adults but also on the pine tree logs, suggesting that the adults were killed by the fungus on the pine. A formulated ERL836 powder treatment on larvae-infested pine logs showed high insecticidal activity against adults, similar to that with the fungal powder suspension treatment, but we demonstrated that using the fungal powder was simpler than using the suspension in field conditions. Even in the field condition, the fungal powder treatment showed high insecticidal activity against <em>M. alternatus</em> adults, which we attribute to its ability to maintain fungal activity for a long time in field conditions by covering the pine tree logs with a film during overwintering. We confirmed that the risk that fungus-infected <em>M. alternatus</em> adults would spread the fungus to other non-target forest insects was low. Thus, even a high-concentration treatment in a specific area is unlikely to transmit the fungus outside that area, so it can be safely used to control this pine wilt nematode vector in forest ecosystems.</span></p>
Distribution. Most records come from either New Zealand or the Atlantic coast of South America, but also recorded in Tasmania, Western Australia, and South Africa; distribution remains unclear due to the small number of confirmed strandings. There are no records of this species between New Zealand and the Pacific coast of South America, but it is unclear whether this represents a break in distribution or a lack of research activity in this region. Earlier records from the Pacific coast of USA have since been reclassified as Perrin's Beaked Whale (M. perrini). in Ziphiidae

Long-term health-related quality of life, healthcare utilisation and back-to-work activities in Intensive Care Unit survivors: prospective confirmatory study from the Frisian Aftercare Cohort
<p>More substantial information on recovery after Intensive Care Unit (ICU) admission is urgently needed. In a previous retrospective study, the proportion of non-recovery patients was 44%. The aim of this prospective follow-up study was to evaluate changes Health-Related Quality of Life (HRQoL) in the first year after ICU-admission. Long-stay adult ICU-patients (≥ 48 hours) were included. HRQoL was evaluated with the Dutch translation of the RAND-36 item Health Survey (RAND-36) at baseline via proxy measurement, and at three, six, and twelve months after ICU admission. Subsequently, the relation between physical functioning, healthcare utilisation, and work activities was explored. </p>
Songbird Activity
<p>This study was conducted in Burnaby, British Columbia between April 15, 2022 and June 21, 2022.<br> Using a Samsung Galaxy J320W8, I have compiled 369 recordings of songbird activity including song sparrows, chickadees, towhees and warblers. These songbirds are among the most prominent in Southwestern British Columbia. For the purpose of this project, I have used the free version of the AlfredCamera application, which gets triggered by any motion and records up to 30 seconds of footage in mp4 format.<br> The intent of this project is multi-fold:<br> - Study songbird activity in urban areas,<br> - Quantify the suitability to songbirds of an urban yard given its proximity to dwellings, noise level and vegetation type,<br> - Analyze the songbird population by using statistical tools,<br> - Paint an accurate picture of the songbird population,<br> - Create a reliable tool to enable citizen scientists to replicate this experiment and gather useful information to ensure the existence of vegetation and greenery in which songbirds thrive.<br> </p>
Data from: Design of cinnamaldehyde amino acid Schiff base compounds based on the quantitative structure–activity relationship
Cinnamaldehyde amino acid Schiff base (CAAS) is a new class of safe, bioactive compounds which could be developed as potential antifungal agents for fungal infections. To design new cinnamaldehyde amino acid Schiff base compounds with high bioactivity, the quantitative structure–activity relationships (QSARs) for CAAS compounds against Aspergillus niger (A. niger) and Penicillium citrinum (P. citrinum) were analysed. The QSAR models (R2 = 0.9346 for A. niger, R2 = 0.9590 for P. citrinum,) were constructed and validated. The models indicated that the molecular polarity and the Max atomic orbital electronic population had a significant effect on antifungal activity. Based on the best QSAR models, two new compounds were designed and synthesized. Antifungal activity tests proved that both of them have great bioactivity against the selected fungi.
Data from: Type 1 interferon-inducible gene expression in QuantiFERON Gold TB-positive uveitis: a tool to stratify a high versus low risk of active tuberculosis?
QuantiFERON-Gold TB (QFT)-positive patients with undetermined cause of uveitis are problematic in terms of whether to diagnose and treat them for tuberculosis (TB). Here, we investigated whether peripheral blood expression of type 1 interferon (IFN)-inducible genes may be of use to stratify QFT-positive patients with uveitis into groups of high versus low risk of having active TB-associated uveitis. We recruited all new uveitis patients in Cipto Mangunkusumo Hospital, Jakarta, Indonesia for one year. We included 12 patients with uveitis and clinically diagnosed active pulmonary TB, 58 QFT-positive patients with uveitis of unknown cause, 10 newly diagnosed sputum-positive active pulmonary TB patients without uveitis and 23 QFT-negative healthy controls. Expression of 35 type 1 IFN-inducible genes was measured in peripheral blood cells from active pulmonary TB patients without uveitis and healthy controls. Differentially expressed genes were identified and used for further clustering analyses of the uveitis groups. A type-1 IFN gene signature score was calculated and the optimal cut-off value for this score to differentiate active pulmonary TB from healthy controls was determined and applied to QFT-positive patients with uveitis of unknown cause. Ten type 1 IFN-inducible genes were differentially expressed between active pulmonary TB and healthy controls. Expression of these 10 genes in QFT-positive patients with uveitis of unknown cause revealed three groups: 1); patients resembling active pulmonary TB, 2); patients resembling healthy controls, and 3); patients displaying an in-between gene expression pattern. A type 1 IFN gene signature score ≥5.61 displayed high sensitivity (100%) and specificity (91%) for identification of active TB. Application of this score to QFT-positive patients with uveitis of unknown cause yielded two groups with expected different likelihood (high vs. low) of having active-TB uveitis, and therefore may be useful in clinical management decisions.
