Multi-interacting global-change drivers reduce photosynthetic and resource use efficiencies and prompt a microzooplankton-phytoplankton uncoupling in estuarine communities.

Plankton communities are subjected to multiple global change drivers; however, it is unknown how the interplay between them deviates from predictions based on single-driver studies, in particular when trophic interactions are explicitly considered. We investigated how simultaneous manipulation of temperature, pH, nutrient availability and solar radiation quality affects the carbon transfer from phytoplankton to herbivorous protists and their potential consequences for ecosystem functioning. Our results showed that multiple interacting global-change drivers reduced the photosynthetic (gross primary production-to-electron transport rates ratios, from 0.

Integrating genetics, metabolites, and clinical characteristics in predicting cardiometabolic health outcomes using machine learning algorithms - A systematic review.

Background: Machine learning (ML) integration of clinical, metabolite, and genetic data reveals variable results in predicting cardiometabolic health (CMH) outcomes. Therefore, we aim to (1) evaluate whether a multi-modal approach incorporating all three data types using ML algorithms can improve CMH outcome prediction compared to single-modal or paired-modal models, and (2) compare the methodologies used in existing prediction models.

Methods: We systematically searched five databases from 1998 to 2024 for ML predictive modelling studies using the multi-modal approach for CMH outcomes.

Unusual high fluorescence of a 7,7'-diazaisoindigo derivative: A photophysical study.

7,7'-Diazaisoindigos are π-conjugated compounds but with poor luminescence properties. Their poor luminescence is generally attributed to the twisting around the central C-C bond in the excited state which favors non-radiative decay. We have found an unusual high fluorescence quantum yield (Φ ≈ 15 %) in a N,N‑Octyl-7,7'-diazaisoindigo derivative incorporating two triphenylamine (TPA) subunits at 5,5'-positions (called compound 12).

Nocardiosis in domestic ferrets (Mustela putorius furo).

Nocardia spp are ubiquitous, gram-positive, variably acid-fast, branching and beaded filamentous, facultative intracellular bacteria that are resistant to phagocytosis and can cause localized or systemic disease in a variety of mammals, including humans, as well as in birds, fish and reptiles. Seventeen pet domestic ferrets (Mustela putorius furo) were diagnosed with nocardiosis by several methods including cytological evaluation, histopathology, Ziehl-Neelsen staining and polymerase chain reaction (PCR). All except two ferrets were 2 years old or older at the time of clinical presentation.

Safety assessment of natural materials for food contact in high temperature applications: Migration studies with solid simulant (Tenax®).

The concern of conventional plastics for food contact has opened the use of natural vegetal materials which can be used even at high temperature. However, their safety in use has to be carefully evaluated. This study shows the migration tests of volatile compounds to Tenax® at 175 °C for 1 h.

How does the measurement of anesthetic depth using the patient state index influence the course of electroconvulsive therapy in patients with major depressive disorder?

Background: Determining anesthetic depth has been used to assess the optimal timing of electrical stimulus application in electroconvulsive therapy (ECT). This has improved the quality and effectiveness of seizures, as some anesthetics used can decrease efficacy. This study evaluated the influence of the Patient State Index (PSi) on the course of ECT in patients with major depressive disorder (MDD).

DNA methylation landscapes before and after Pacific Oyster Mortality Syndrome are different within and between resistant and susceptible Magallana gigas.

Pacific oysters face recurring outbreaks of Pacific Oyster Mortality Syndrome (POMS), a polymicrobial multifactorial disease. Although this interaction is increasingly understood, the role of epigenetics (e.g.

Appropriateness of urine culture requests in primary care in Spain: A cross-sectional descriptive study.

Objective: Studies evaluating urine culture requests in our country have highlighted a high rate of requests that fall outside the indications specified in clinical guidelines. We evaluated the current degree of inadequacy in the request of urine cultures and how this influences the therapeutic decisions of general practitioners.

Design: Cross-sectional descriptive study.

Preliminary Evidence for Perturbation-Based tACS-EEG Biomarkers of Gamma Activity in Alzheimer's Disease.

Background: Alzheimer's disease (AD) is characterized by impaired inhibitory circuitry and GABAergic dysfunction, which is associated with reduced fast brain oscillations in the gamma band (γ, 30-90 Hz) in several animal models. Investigating such activity in human patients could lead to the identification of novel biomarkers of diagnostic and prognostic value. The current study aimed to test a multimodal "Perturbation-based" transcranial Alternating Current Stimulation-Electroencephalography (tACS)-EEG protocol to detect how responses to tACS in AD patients correlate with patients' clinical phenotype.

5-FU Weakens Defensive Functions of the Junctional Epithelium.

Aim: To investigate additional factors contributing to the pathophysiology of chemotherapy-induced oral mucositis and periodontitis beyond the systemic immune suppression caused by the chemotherapeutic agent 5-Fluorouracil (5-FU).

Methods: 5-Fluorouracil was topically delivered to the non-keratinized, rapidly proliferating junctional epithelium (JE) surrounding the dentition, and acts as an immunologic and functional barrier to bacterial ingression. Various techniques, including EdU incorporation, quantitative immunohistochemistry (qIHC), histology, enzymatic activity assays, and micro-computed tomographic (μCT) imaging, were employed to analyze the JE at multiple time points following topical 5-FU treatment.

Musculoskeletal differences in the craniomandibular region of children and adolescents with and without bruxism: A comparative study.

Objective: To analyse the relationship between bruxism and musculoskeletal parameters of the cervical and mandibular regions in children and adolescents.

Methods: A comparative cross-sectional study was performed with subjects from 6 to 16 years. Subjects were divided into bruxism (any type) and control groups.

Phase transitions, Dirac and Weyl semimetal states in MnGeBiTe.

Using angle-resolved photoemission spectroscopy (ARPES) and density functional theory (DFT), an experimental and theoretical study of changes in the electronic structure (dispersion dependencies) and corresponding modification of the energy band gap at the Dirac point (DP) for topological insulator (TI) [Formula: see text] have been carried out with gradual replacement of magnetic Mn atoms by non-magnetic Ge atoms when concentration of the latter was varied from 10% to 75%. It was shown that when Ge concentration increases, the bulk band gap decreases and reaches zero plateau in the concentration range of 45-60% while trivial surface states (TrSS) are present and exhibit an energy splitting of 100 and 70 meV in different types of measurements. It was also shown that TSS disappear from the measured band dispersions at a Ge concentration of about 40%.

Monitoring of Selected Swine Viral Diseases in Peruvian Amazon Peccaries.

Peccaries (collared peccary-CP-and white-lipped peccary-WLP) are an essential source of protein and income for rural communities in the Amazon region. Since 1980s, researchers in the Amazon have reported recurrent local disappearances of WLP populations. Although such disappearances impact the species conservation and the food security of rural societies, no studies have drawn consistent conclusions about the causes of these population collapses.

Diverse real-life outcomes after intensive risk-adapted therapy for 1034 AML patients from the CETLAM Group.

Given the heterogeneity of acute myeloid leukemia patients, it is necessary to identify patients considered fit for intensive therapy but who will perform poorly, and in whom alternative approaches deserve investigation. We analyzed 1034 fit adults ≤70 years intensively treated between 2012 and 2022 in the CETLAM group. Young adults ( ≤ 60 years) presented higher remission rates and improved survival than older adults above that age (CR 79% vs.

Some thoughts about the "Consensus statement on smoking and vascular risk" from the Spanish Autonomous Societies of Hypertension and Vascular Risk.

Smoking is a known preventable risk factor for vascular diseases. However, it is one of the most forgotten risks when we talk about its relationship with kidney disease. Following the publication of the "Consensus statement on smoking and vascular risk" promoted by the autonomous societies of hypertension and vascular risk of Spain, we consider that the nephrology community should be alerted about the deleterious effects of exposure to tobacco smoke and its consequences on renal damage.

System identification and fault reconstruction in solar plants via extended Kalman filter-based training of recurrent neural networks.

This article proposes using the extended Kalman filter (EKF) for recurrent neural network (RNN) training and fault estimation within a parabolic-trough solar plant. The initial step involves employing an RNN to model the system. Given the challenge of fault discernibility in the collectors, parallel EKFs are employed to reconstruct the parameters of the faults.

Risk of intrafascicular spread after deliberate ex vivo intraneural injections of brachial plexus nerve roots.

Background: We investigated the intraneural spread of injected fluid in brachial plexus nerve roots, examining the potential for intrafascicular spread and identifying influencing factors.

Methods: Twelve deliberate ultrasound-guided intraneural injections were performed at the ventral rami of the brachial plexus nerve roots at their exits from the neuroforamina in six fresh, unembalmed, cryopreserved human cadavers. A 22-G, 30-degree bevel echogenic regional anaesthesia needle was used.

Quality of Headache Management in Inpatients.

Purpose: Headache is a prevalent and highly disabling neurological disorder. There are no data on its prevalence in and impact on hospitalized patients. The objective of this study was to describe the prevalence of headache in hospitalized patients, triggers associated with headaches in this population, and compliance with documentation in the electronic medical record system (EMRS).

Axial spondyloarthritis.

Axial spondyloarthritis manifests as a chronic inflammatory disease primarily affecting the sacroiliac joints and spine. Although chronic back pain and spinal stiffness are typical initial symptoms, peripheral (ie, enthesitis, arthritis, and dactylitis) and extra-musculoskeletal (ie, uveitis, inflammatory bowel disease, and psoriasis) manifestations are also common. Timely and accurate diagnosis is challenging and relies on identifying a clinical pattern with a combination of clinical, laboratory (HLA-B27 positivity), and imaging findings (eg, structural damage on pelvic radiographs and bone marrow oedema on MRI of the sacroiliac joints).
