Time Reveals the Truth! What Treatments for COVID-19 Were Quickly Abandoned, and Which Methods, Contrary to Popular Belief, Are Still Flourishing?

During the early days of the COVID-19 pandemic, low dose radiation therapy (LDRT) was proposed as a potentially effective treatment method. To minimize potential toxicity, the initial treatment approach involved a few mGy of adapting radiation followed by a single 250 mGy whole lung challenging dose. However, antiviral drugs were also introduced as a promising treatment option, which were thought to have the potential to revolutionize the management of the crisis.

Pulmonary consequences of experimentally induced stroke: differences between global and focal cerebral ischemia.

Introduction: Cerebral ischemia leads to multiple organ dysfunctions, with the lungs among the most severely affected. Although adverse pulmonary consequences contribute significantly to reduced life expectancy after stroke, the impact of global or focal cerebral ischemia on respiratory mechanical parameters remains poorly understood.

Methods: Rats were randomly assigned to undergo surgery to induce permanent global cerebral ischemia (2VO) or focal cerebral ischemia (MCAO), or to receive a sham operation (SHAM).

Unbiased Drug Target Prediction Reveals Sensitivity to Ferroptosis Inducers, HDAC and RTK Inhibitors in Melanoma Subtypes.

Background: The utilization of PD1 and CTLA4 inhibitors has revolutionized the treatment of malignant melanoma (MM). However, resistance to targeted and immune-checkpoint-based therapies still poses a significant problem.

Objective: Here, we mine large-scale MM proteogenomic data to identify druggable targets and forecast treatment efficacy and resistance.

An update on access to novel treatment for metastatic melanoma in Europe - A 2024 survey of the European melanoma registry and the European association of dermato-oncology.

Advances in cancer treatments have significantly improved their effectiveness, yet access to first-line therapies remains limited. A 2017 survey revealed that over 25 % of metastatic melanoma patients in Europe lacked access to recommended therapies. To address this, the European Association of Dermato-Oncology and the European Melanoma Registry conducted a follow-up study on the registration and reimbursement of first-line treatments.

The response to shock loads of Ni-MOF and NiO NPs on aerobic granular sludge and algal-bacterial aerobic granular sludge.

Currently, the increasing use of nickel metal-organic frameworks (Ni-MOF) and nickel oxide nanoparticles (NiO NPs) has raised concerns regarding their potential environmental impact on wastewater treatment systems. Herein, the responses of aerobic granular sludge (AGS) and algal-bacterial aerobic granular sludge (AB-AGS) to Ni-MOF and NiO NPs were investigated. The results showed that Ni-MOF concentrations of 50, 100, and 200 mg/L significantly reduced nutrient removal in both systems, particularly affecting ammonia, nitrite, and phosphorus removal, while denitrification processes remained stable.

Optimizing sequence data analysis using convolution neural network for the prediction of CNV bait positions.

Background: Accurate prediction of copy number variations (CNVs) from targeted capture next-generation sequencing (NGS) data relies on effective normalization of read coverage profiles. The normalization process is particularly challenging due to hidden systemic biases such as GC bias, which can significantly affect the sensitivity and specificity of CNV detection. In many cases, the kit manifests provide only the genome coordinates of the targeted regions, and the exact bait design of the oligo capture baits is not available.

Single Particle Dynamics at the Free Surface of Imidazolium-Based Ionic Liquids.

In this work, we carry out a systematic computer simulation investigation of the single particle dynamics at the free surface of imidazolium-based room temperature ionic liquids by applying intrinsic surface analysis. Besides assessing the effect of the potential model and temperature, we focus in particular on the effect of changing the anion type, and, hence, their shape and size. Further, we also address the role of the length of the cation alkyl chains, known to protrude into the vapor phase, on the surface dynamics of the ions.

Respiratory Viruses in Patients With Hematological Malignancy in Boreal Autumn/Winter 2023-2024: EPICOVIDEHA-EPIFLUEHA Report.

Community-acquired respiratory viral infections (CARV) significantly impact patients with hematological malignancies (HM), leading to high morbidity and mortality. However, large-scale, real-world data on CARV in these patients is limited. This study analyzed data from the EPICOVIDEHA-EPIFLUEHA registry, focusing on patients with HM diagnosed with CARV during the 2023-2024 autumn-winter season.

Fluorescence Detection of DNA/RNA G-Quadruplexes (G4s) by Twice-as-Smart Ligands.

Fluorescence detection of DNA and RNA G-quadruplexes (G4s) is a very efficient strategy to assess not only the existence and prevalence of cellular G4s but also their relevance as targets for therapeutic interventions. Among the fluorophores used to this end, turn-on probes are the most interesting since their fluorescence is triggered only upon interaction with their G4 targets, which ensures a high sensitivity and selectivity of detection. We reported on a series of twice-as-smart G4 probes, which are both smart G4 ligands (whose structure is reorganized upon interaction with G4s) and smart fluorescent probes (whose fluorescence is turned on upon interaction with G4s).

Long-read Transcriptomics of Caviid Gammaherpesvirus 1: Compiling a Comprehensive RNA Atlas.

Caviid gammaherpesvirus 1 (CaGHV-1), formerly known as the guinea pig herpes-like virus, is an oncogenic gammaherpesvirus with a sequenced genome but an as-yet uncharacterized transcriptome. Using nanopore long-read RNA sequencing, we annotated the CaGHV-1 genome and constructed a detailed transcriptomic atlas. Our findings reveal diverse viral mRNAs and non-coding RNAs, along with mapped promoter elements for each viral gene.

Interaction between Uranyl Cations and Layered Double Hydroxide Nanoparticles: Implications for Nuclear Wastewater Management.

Effective uranium (U) capture is required for the remediation of contaminated solutes associated with the nuclear fuel cycle, including fuel reprocessing effluents, decommissioning, or nuclear accident cleanup. Here, interactions between uranyl cations (UO ) and a Mg-Al layered double hydroxide (LDH) were investigated using two types of uranyl-bearing LDH colloids. The first (ULDH) was synthesized by coprecipitation with 10% of Mg substituted by UO .

Experimental horizontal transfer of phage-derived genes to Drosophila confers innate immunity to parasitoids.

Metazoan parasites have played a major role in shaping innate immunity in animals. Insect hosts and parasitoid wasps are excellent models for illuminating how animal innate immune systems have evolved to neutralize these enemies. One such strategy relies on symbioses between insects and intracellular bacteria that express phage-encoded toxins.

Beyond the boundaries: Transitioning from categorical to dimensional paradigms in mental health diagnostics.

Mental health diagnostics is undergoing a transformation, with a shift away from traditional categorical systems like the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), and the International Classification of Diseases, 11th Revision (ICD-11), and toward innovative frameworks like the Hierarchical Taxonomy of Psychopathology (HiTOP) and the Research Domain Criteria (RDoC). These emerging models prioritize dimensional and biobehavioral approaches in order to overcome limitations such as oversimplification, comorbidity and heterogeneity. This editorial explores the challenges of implementing these paradigms, such as the need for empirical validation, interdisciplinary collaboration and clinician training.

Solution equilibrium and redox properties of metal complexes with 2-formylpyridine guanylhydrazone derivatives: Effect of morpholine and piperazine substitutions.

Schiff bases derived from aminoguanidine are extensively investigated for their structural versatility. The tridentate 2-formylpyridine guanylhydrazones act as analogues of 2-formyl or 2-acetylpyridine thiosemicarbazones, where the thioamide unit is replaced by the guanidyl group. Six derivatives of 2-formylpyridine guanylhydrazone were synthesized and their proton dissociation and complex formation processes with Cu(II), Fe(II) and Fe(III) ions were studied using pH-potentiometry, UV-visible, NMR and electron paramagnetic resonance spectroscopic methods.

This systematic review evaluates the efficacy of analogue and virtual typodont/simulation training in orthodontic education, focusing on its impact on clinical skills, motivation, and communication (PROSPERO ID# CRD42024560497). A comprehensive search across PubMed, the Cochrane Library, ERIC, and CINAHL identified 11 studies that examined various simulation-based learning approaches. The findings indicate that simulation-based training enhances short-term diagnostic accuracy, treatment planning, and practical skills in orthodontics, particularly in tasks such as bracket bonding and clinical reasoning.

Structural mechanism of CBR binding to peripheral and biased inverse agonists.

The cannabinoid receptor 1 (CBR) regulates synaptic transmission in the central nervous system, but also has important roles in the peripheral organs controlling cellular metabolism. While earlier generations of brain penetrant CBR antagonists advanced to the clinic for their effective treatment of obesity, such molecules were ultimately shown to exhibit negative effects on central reward pathways that thwarted their further therapeutic development. The peripherally restricted CBR inverse agonists MRI-1867 and MRI-1891 represent a new generation of compounds that retain the metabolic benefits of CBR inhibitors while sparing the negative psychiatric effects.

Diffusion-driven growth of calcium carbonate polymorphs in microchannels.

We propose a novel approach to characterize the growth of individual crystals. Calcium chloride and sodium carbonate solutions have been injected into a Y-shaped microfluidic channel at various stoichiometric ratios, and the development of calcium carbonate has been monitored. The formation of calcite and vaterite depends not only on the stoichiometric ratio of the reactants but also on the region of the reactor where they form.

Leveraging Agri-advocacy to promote animal genetic diversity for climate change mitigation: Kenya and Tanzania perspective.

The role that genetic diversity in animal genetic resources (AnGR) plays in mitigating the effects of climate change on the global protein supply is of the utmost significance. East Africa historically played a pivotal role in the dispersal of domesticated livestock species across the African continent. At present, it maintains a substantial contribution to worldwide biodiversity as a result of its reservoir of a diverse array of AnGR, characterized by genetic and species diversity.

Benefits and challenges of the integration of haptics-enhanced virtual reality training within dental curricula.

Background: Haptics-enhanced virtual reality (VR-haptic) simulation in dental education has evolved considerably during the past decade, representing a promising resource of simulation-based training opportunities to support conventional practice. We aim to summarize current literature on the applications of VR-haptics in learning, practicing, and teaching dental education.

Methods: A literature search was performed using PubMed, focusing on research articles published between January 2010 and January 2024.

Concomitant virus infection increases mortality and worsens outcome of acute pancreatitis: A systematic review and meta-analysis.

Background: Acute pancreatitis (AP) is a major health threat, with a high mortality rate in severe forms. Though alcohol and bile-induced factors are the most common causes, increasing evidence suggests that viral infections such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and human immunodeficiency virus (HIV) may also trigger AP development. Our study aims to explore this association in greater detail.

Air Pollution and Myocardial Infarction-A New Smoker's Paradox?

Ambient air pollution is a significant public health concern, known to affect cardiovascular health adversely. Research has identified both long-term and short-term cardiovascular risks associated with various air pollutants, including those linked to acute coronary syndromes. However, the observed effects are rather small, with most data sourced from highly polluted regions.

Subclinical Left Atrial Remodeling in Healthy Adults with Left Ventricular 'Rigid Body Rotation'-Detailed Analysis from the Three-Dimensional Speckle-Tracking Echocardiographic MAGYAR-Healthy Study.

While the basal region of the left ventricle (LV) rotates in a clockwise (cw) direction, the apical regions of the LV rotate in a counterclockwise (ccw) direction in healthy circumstances. Although LV rotational mechanics help optimize LV ejection, in some cases, LV twist is missing. This clinical situation, when the LV base and the apex rotate in the same cw or ccw direction, is called LV 'rigid body rotation' (LV-RBR).
