This research evaluated the impact of incorporating dried olive pulp (OP) into the feed of laying hens on the fatty acid profile, cholesterol, triglyceride, total phenolic, oleuropein and hydroxytyrosol content, and health lipid indices of eggs produced by mid- (39 weeks) and late-laying (59 weeks) birds. Over a 36-week trial, 300 eggs from 180 Isa-Brown hens, assigned to three dietary groups with different OP levels (CON, OP4 and OP6), were analyzed. OP reduced egg cholesterol, with significant effects in late-age eggs ( < 0.

The neonatal intensive care unit (NICU) population, especially low birth weight and critically ill neonates, is at risk of invasive infections, which are associated with high mortality rates and unfavorable long-term outcomes. The timely initiation of an appropriate antifungal treatment has been demonstrated to enhance the prognosis. Factors that should be considered in the choice of an antifungal agent include the causative strain, the presence and location of deep tissue infection, any previous use of antifungal prophylaxis, and the presence of implanted devices.

Background: There is currently increasing interest in the implication of traumatic brain injury (TBI) as a potential risk factor for long-term neurodegenerative conditions, such as dementia and Alzheimer's disease (AD). In this context, we performed a systematic review and meta-analysis to evaluate the association between TBI and the risk of dementia.

Methods: A systematic search was performed across multiple electronic databases, including PubMed, Embase, and Cochrane Library, to identify relevant meta-analyses and cohort studies.

Background/objectives: Medullary thyroid carcinoma (MTC) is a highly aggressive tumor, as it is characterized by a high probability of local recurrence and distant metastases, even after surgical treatment. Early detection of disease recurrence is critical for improving long-term treatment outcomes and overall patient survival. By comparing different radiopharmaceuticals, this analysis aimed to strengthen existing guidelines and help bridge the gap between the recommendations of the ESMO and the ATA, highlighting the importance of PET/CT scanning in the postoperative follow-up of patients with MTC.

Background/objectives: Exosomes, nano-sized extracellular vesicles released by all cells, play a key role in intercellular communication and carry tumorigenic properties that impact surrounding or distant cells. The complexity of the exosomal molecular interactome and its effects on recipient cells still remain unclear. This study aims to decipher the molecular profile and interactome of lung adenocarcinoma A549 cell-derived exosomes using multi-omics and bioinformatics approaches.

Introduction: Despite the well-documented benefits of smoking cessation interventions, the implementation and success of these programs in primary care settings often encounter significant barriers. A primary care provider's personal smoking status has been identified as a potential barrier to tobacco treatment delivery. The aim of this qualitative study is to explore the experiences and perspectives of primary care providers regarding their role in delivering smoking cessation interventions to patients based on their personal smoking status.

Introduction: The impact of multidisciplinary supervised cardiac rehabilitation programs on reducing the risk of having heart problems in the future is well documented. However, little is known about nurse-led post-coronary heart disease (post-CHD).

Purpose: Our aim was to evaluate the effectiveness of an educational and counseling-structured nurse-led post-CHD support program by assessing the prediction of psychological, behavioral and dietary variables in relation to adherence to a care plan in a single hospital in Athens (Greece).

Oxidative Status and Lipid Metabolism Analytes in Dogs with Mast Cell Tumors: A Preliminary Study.

Antioxidants (Basel)

November 2024

Diagnostic Laboratory, School of Veterinary Medicine, Faculty of Health Sciences, Aristotle University of Thessaloniki, 546 27 Thessaloniki, Greece.

Mast cell tumors (MCTs) are common skin neoplasms in dogs. Prognostic indicators include histologic grade, clinical stage, high Ki-67 index, elevated argyrophilic nucleolus organizer regions (AgNOR) index, mutations, and recurrence after surgery. Blood serum redox status has been shown to correlate with prognostic factors in canine lymphoma and mammary tumors.

21 century surface UV radiation changes deduced from CMIP6 models: part I-evolution of major influencing factors.

Photochem Photobiol Sci

January 2025

Institute of Meteorology and Climate Research Atmospheric Trace Gases and Remote Sensing, Karlsruhe Institute of Technology, Karlsruhe, Germany.

For a given solar elevation, the levels of solar ultraviolet radiation at the Earth's surface are determined by the amounts of ozone, aerosols, and clouds, as well as by the reflectivity of the surface. Here, we study the evolution of these factors for three selected decades in the period 1950-2100 using results from simulations with Earth-System models (ESMs) participating in the 6 phase of the Coupled Model Intercomparison Project (CMIP6). The simulations for the future are based on three Shared Socioeconomic Pathways: SSP1-2.

Pharmaceutical nanosuspensions, also called nanocrystals, are heterogeneous mainly aqueous dispersions of insoluble drug particles stabilised by surfactants and/or polymers. Nanosuspensions as liquid formulations suffer from instability. Solidification of nanosuspensions to solid dosage forms is a way to combine the advantages of nanocrystals with the advantages of the solid state.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Article Synopsis
  • Understanding posture is crucial for how mammals move, and dysregulation of certain brain chemicals, specifically dopamine and noradrenaline, can lead to motor problems in diseases like spinal muscular atrophy (SMA).
  • Research using a mouse model of SMA revealed that the loss of synapses in the spinal neurons, caused by non-cell autonomous mechanisms, contributes to motor dysfunction and postural issues.
  • Restoring a specific protein (survival motor neuron) in either catecholaminergic or serotonergic neurons can improve movement, but significant postural issues only improve with restoration in both neuron types or treatment with l-dopa, highlighting new potential treatment strategies.

Three-quarters of the planet's land surface has been altered by humans, with consequences for animal ecology, movements and related ecosystem functioning. Species often occupy wide geographical ranges with contrasting human disturbance and environmental conditions, yet, limited data availability across species' ranges has constrained our understanding of how human pressure and resource availability jointly shape intraspecific variation of animal space use. Leveraging a unique dataset of 758 annual GPS movement trajectories from 375 brown bears (Ursus arctos) across the species' range in Europe, we investigated the effects of human pressure (i.
