Given the significant environmental consequences of current poultry feed practices and the heavy dependence of the European Union on imported soybeans, studying alternatives is crucial. This study evaluated the potential benefits of using locally sourced alternative plant-based ingredients and whole dry black soldier fly larvae in the diet of laying hens. The experiment involved 120 Isazul hens at 23 weeks old, which were divided into three groups with five replicates each (eight hens per replicate): a control diet (CON) based on soybean meal and cereals, an alternative diet (ALT) replacing the soybean meal with locally sourced plant-based resources (peas, distillers' dried grains with solubles, and sunflower meal), and the ALT diet supplemented with 5% whole dry black soldier fly larvae (ALT+DBSFL).

Chronic diseases usually require repetitive dosing. Depending on factors such as dosing frequency, mode of administration, and associated costs this can result in poor patient compliance. A better alternative involves using drug delivery systems to reduce the frequency of dosing and extend drug release.

Article Synopsis
  • Immune thrombocytopenia (ITP) leads to low platelet counts due to increased destruction and is classified based on the time post-diagnosis: newly diagnosed, persistent, and chronic.
  • The TAPER trial studied eltrombopag as a treatment option for adults with ITP who didn't respond to corticosteroids, finding that about 30.5% of participants achieved a sustained response off-treatment after a year.
  • Eltrombopag improved platelet counts and quality of life within a few months, with a median duration of sustained response extending to about 22 months in later follow-ups, while maintaining a safety profile consistent with prior studies.

Experimental studies of TiO nanotubes have been conducted for nearly three decades and have revealed the remarkable advantages of this material. Research based on computer simulations is much rarer, with research using density functional theory (DFT) being the most significant in this field. It should be noted, however, that this approach has significant limitations when studying the macroscopic properties of nanostructures such as nanosheets and nanotubes.

This phase 2 study evaluated isatuximab as monotherapy or combined with dexamethasone in relapsed/refractory multiple myeloma (RRMM). Patients had RRMM refractory to an immunomodulatory drug (IMiD) and a proteasome inhibitor (PI) or had received ≥3 prior lines of therapy incorporating an IMiD and PI. Patients received isatuximab either as monotherapy (20 mg/kg on days 1, 8, 15, and 22 [once weekly] of cycle 1 followed by 20 mg/kg on days 1 and 15 of subsequent cycles; Isa group) or in combination with dexamethasone (40 mg/d [20 mg/d in patients aged ≥75 years] once weekly; Isa-dex group).

Agents that need to act on their surroundings can significantly benefit from the perception of their interaction possibilities or affordances. In this paper we combine the benefits of the Interaction Tensor, a straight-forward geometrical representation that captures multiple object-scene interactions, with deep learning saliency for fast parsing of affordances in the environment. Our approach works with visually perceived 3D pointclouds and enables to query a 3D scene for locations that support affordances such as sitting or riding, as well as interactions for everyday objects like the where to hang an umbrella or place a mug.

Experiencing HIV-related stigma has important impacts on the mental health of people living with HIV, which has implications for treatment adherence, disease progression, and health outcomes. The impacts of stigma are particularly important to consider among sexual and gender minorities, who often face a disproportionate burden of HIV. To address the implications of stigma in these key populations, we leveraged a longitudinal study conducted among Peruvian sexual and gender minorities to compare the relative effects of multiple mediators affecting the relationship between experienced HIV-related stigma and psychological distress: internalized HIV-related stigma, adaptive coping, and maladaptive coping.

With the increase of ageing population, rates of chronic diseases and complex medical conditions, the management of high-risk surgical patients is likely to become a great concern in most countries. Considering all these factors, it is certainly rational and intuitive that internists should be included into a collaborative model of medical and surgical co-management, where their multi-potentiality and synthesis capacity require them to coordinate the multidisciplinary team and to be the leading agent of change. In this regard, our aim was to present the official position and approach of the Working Group on Professional Issues and Quality of Care of the European Federation of Internal Medicine (EFIM), for implementation of this strategy of care, encouraging internists to assume an important role and to provide continuity of multidisciplinary care, from the decision to operate through to rehabilitation and recovery.

Oceanic islands are vulnerable ecosystems and their flora has been under pressure since the arrival of the first humans. Human activities and both deliberately and inadvertently introduced biota have had and continue to have a severe impact on island endemic plants. The number of alien plants has increased nearly linearly on many islands, perhaps resulting in extinction-based saturation of island floras.

The climbing habit is a key innovation in plants: climbing taxa have higher species richness than nonclimbing sister groups. We evaluated the hypothesis that climbing plant species show greater among-population genetic differentiation than nonclimber species. We compared the among-population genetic distance in woody climbers (eight species, 30 populations) and trees (seven species, 29 populations) coexisting in nine communities in a temperate rainforest.

Within a woody plant species, environmental heterogeneity has the potential to influence the distribution of genetic variation among populations through several evolutionary processes. In some species, a relationship between environmental characteristics and the distribution of genotypes can be detected, showing the importance of natural selection as the main source of differentiation.

Article Synopsis
  • Adaptive radiation is a process where plants from oceanic islands diversify into different species (cladogenesis), while some species evolve through gradual changes without splitting (anagenesis).
  • Research in the Juan Fernández Archipelago shows that anagenetic species have more genetic variation within island populations and lack geospatial genetic differences, unlike cladogenetic species.
  • Additionally, anagenetic species on older islands show higher genetic variability than those on younger islands, and the total genetic variation remains similar across genera, regardless of the type of speciation.

Gallium nanoparticles (GaNPs) of different sizes are deposited on Si(100) substrates by thermal evaporation. Through ellipsometric analysis, it is possible to investigate the plasmonic effects in the GaNPs and exploit them to develop biosensors. The excitation of the resonant modes for certain incidence angles leads to negative values of the imaginary part of the pseudodielectric function (<εi>) obtained in ellipsometry.

A common mode of speciation in oceanic islands is by anagenesis, wherein an immigrant arrives and through time transforms by mutation, recombination, and drift into a morphologically and genetically distinct species, with the new species accumulating a high level of genetic diversity. We investigate speciation in Drimys confertifolia, endemic to the two major islands of the Juan Fernández Archipelago, Chile, to determine genetic consequences of anagenesis, to examine relationships among populations of D. confertifolia and the continental species D.
