Aim Of Study: We aimed to compare knowledge, opinions, and clinical experiences among Czech, Slovak, and Italian neurologists to identify potential educational gaps and unify understanding.

Clinical Rationale For Study: Functional neurological disorder (FND) is a disabling condition characterised by motor, sensory, or cognitive symptoms which are incompatible with other neurological disorders. Novel diagnostic and treatment approaches have improved FND management.

The surface modification of the silica-coated magnetic nanoparticles and their application in molecular diagnostics of virus infection.

The study presents a series of examples of magnetic nanoparticle systems designed for the diagnosis of viral diseases. In this interdisciplinary work, we describe one of the most comprehensive synthetic approaches for the preparation and functionalization of smart nanoparticle systems for rapid and effective RT-PCR diagnostics and isolation of viral RNA. Twelve different organic ligands and inorganic porous silica were used for surface functionalization of the FeO magnetic core to increase the number of active centres for efficient RNA binding from human swab samples.

Neural bases of social deficits in ADHD: A systematic review. Does the Theory of Mind matter?

Introduction: The Attention Deficit Hyperactivity Disorder (ADHD) causes serious interpersonal problems from childhood to adulthood, one of them being problematic social functioning. This phenomenon in ADHD should be associated with impairments in the Theory of Mind (ToM). Therefore, understanding the neural correlates of the ToM could be crucial for helping individuals with ADHD with their social functioning.

SCORE2 Screening Tool for Cardiovascular Risk Assessment in Psoriasis-A Case-Control Study.

: Psoriasis is a common, T-cell-mediated inflammatory and immune-mediated skin disease. Numerous studies confirmed that patients with psoriasis have a significant frequency of cardiovascular (CV) risk factors and CV diseases (CVDs). Risk stratification is helpful in light of the elevated risk of CVD in psoriasis patients.

Methods: Specialists from 28 countries were invited to a survey via professional organisations.

Photoproduction of K^{+}K^{-} Pairs in Ultraperipheral Collisions.

K^{+}K^{-} pairs may be produced in photonuclear collisions, either from the decays of photoproduced ϕ(1020) mesons or directly as nonresonant K^{+}K^{-} pairs. Measurements of K^{+}K^{-} photoproduction probe the couplings between the ϕ(1020) and charged kaons with photons and nuclear targets. The kaon-proton scattering occurs at energies far above those available elsewhere.

p.L1795F LRRK2 variant is a common cause of Parkinson's disease in Central Europe.

Pathogenic variants in are one of the most common genetic risk factors for Parkinson's disease (PD). Recently, the lesser-known p.L1795F variant was proposed as a strong genetic risk factor for PD, however, further families are currently lacking in literature.

Design and fabrication of 3D-printed crystallization plates for probing microcrystals in an external electric field.

X-ray crystallography is an established tool to probe the structure of macromolecules with atomic resolution. Compared with alternative techniques such as single-particle cryo-electron microscopy and micro-electron diffraction, X-ray crystallography is uniquely suited to room-temperature studies and for obtaining a detailed picture of macromolecules subjected to an external electric field (EEF). The impact of an EEF on proteins has been extensively explored through single-crystal X-ray crystallography, which works well with larger high-quality protein crystals.

Mini-encyclopedia of mitochondria-relevant nutraceuticals protecting health in primary and secondary care-clinically relevant 3PM innovation.

Despite their subordination in humans, to a great extent, mitochondria maintain their independent status but tightly cooperate with the "host" on protecting the joint life quality and minimizing health risks. Under oxidative stress conditions, healthy mitochondria promptly increase mitophagy level to remove damaged "fellows" rejuvenating the mitochondrial population and sending fragments of mtDNA as SOS signals to all systems in the human body. As long as metabolic pathways are under systemic control and well-concerted together, adaptive mechanisms become triggered increasing systemic protection, activating antioxidant defense and repair machinery.

Targeting Biometals in Alzheimer's Disease with Metal Chelating Agents Including Coumarin Derivatives.

Numerous physiological processes happening in the human body, including cerebral development and function, require the participation of biometal ions such as iron, copper, and zinc. Their dyshomeostasis may, however, contribute to the onset of Alzheimer's disease (AD) and potentially other neurodegenerative diseases. Chelation of biometal ions is therefore a therapeutic strategy against AD.

Optically Actuated Soft Microrobot Family for Single-Cell Manipulation.

Precisely controlled manipulation of nonadherent single cells is often a pre-requisite for their detailed investigation. Optical trapping provides a versatile means for positioning cells with submicrometer precision or measuring forces with femto-Newton resolution. A variant of the technique, called indirect optical trapping, enables single-cell manipulation with no photodamage and superior spatial control and stability by relying on optically trapped microtools biochemically bound to the cell.

Comparative model of minimal spinal cord injury reveals a rather anti-inflammatory response in the lesion site as well as increased proliferation in the central canal lining in the neonates compared to the adult rats.

Spinal cord injury (SCI) resulting from trauma decreases the quality of human life. Numerous clues indicate that the limited endogenous regenerative potential is a result of the interplay between the inhibitory nature of mature nervous tissue and the inflammatory actions of immune and glial cells. Knowledge gained from comparing regeneration in adult and juvenile animals could draw attention to factors that should be removed or added for effective therapy in adults.

Newly Isolated B1/1 Modulates the Expression of Cytokines and Antimicrobial Proteins in a Porcine Model.

Background: The epithelia of the intestine perform various functions, playing a crucial role in providing a physical barrier and an innate immune defense against infections. By generating a "three-dimensional" (3D) model of cell co-cultures using the IPEC-J2 cell line and porcine blood monocyte-derived macrophages (MDMs), we are getting closer to mimicking the porcine intestine Methods: The effect of B1/1 and CCM 7158 (indicator strain) on the relative gene expression of interleukins (IL-1β, IL-6, IL-8, IL-18 and IL-10), genes encoding receptors for TLR4 and TLR2, tight junction proteins such as claudin-1 (CLDN1), occludin (OCLN) and important antimicrobial proteins such as lumican (LUM) and olfactomedin-4 (OLMF-4) was monitored in this model.

Results: The results obtained from this pilot study point to the immunomodulatory potential of newly isolated B1/1, as it was able to suppress the enhanced pro-inflammatory response to lipopolysaccharide (LPS) challenge in both cell types.

A 'Chiron' approach to novel phytosphingosine mimetics based on a cascade [3,3]-sigmatropic rearrangement.

Straightforward access to enantiomerically pure 3,4-diamino-3,4-dideoxyphytosphingosines, as novel analogues of natural d-ribo-phytosphingosine was accomplished, starting from two available chirons: dimethyl l-tartrate and d-isoascorbic acid. A sequential Overman rearrangement followed by late-stage introduction of the alkyl side chain moiety via olefin cross-metathesis is the cornerstone of this approach. The preliminary evaluation study of the synthesised sphingomimetics, based on their ability to inhibit a proliferation of human cancer cells, showed promising cytotoxicity against Jurkat and HeLa cells for (2R,3R,4S)-2,3,4-triaminooctadecan-1-ol trihydrochloride.

Lipoprotein (a) concentration as a risk factor for ischaemic stroke and its subtypes.

Aim Of The Study: To investigate the relationship between serum lipoprotein (a) [Lp(a)] concentration and the risk of ischaemic stroke (IS) and its subtypes.

Clinical Rationale For The Study: Lp(a) plays a role in atherogenic, pro-thrombotic, and antifibrinolytic processes. Elevated plasma Lp(a) is a strong independent risk factor for the development and progression of atherosclerotic disease.

Early Versus Late Initiation of Direct Oral Anticoagulants After Ischemic Stroke in People With Atrial Fibrillation and Hemorrhagic Transformation: Prespecified Subanalysis of the Randomized Controlled ELAN Trial.

Background: Whether hemorrhagic transformation (HT) modifies the treatment effect of early compared with late initiation of direct oral anticoagulation in people with ischemic stroke and atrial fibrillation is unknown.

Methods: This is a post hoc analysis of the ELAN trial (Early Versus Late Initiation of Direct Oral Anticoagulants in Post-Ischaemic Stroke Patients With Atrial Fibrillation). The primary outcome was a composite of recurrent ischemic stroke, symptomatic intracranial hemorrhage, major extracranial bleeding, systemic embolism, or vascular death within 30 days.

Novel surfactant C variant c.325-47_374del without response to hydroxychloroquine treatment.

Pathogenic variants of SP-C, which cause various lung diseases with varying ages of onset, are inherited in an autosomal dominant manner or appear de novo as new mutations. We present a case of fatal respiratory failure in a female infant. Genetic analysis confirmed an intragenic deletion encompassing exon 4 in the SFTPC gene, starting in the intron region before exon 4, extending into the exon 4 and portion, in a heterozygous state.

PIP Is An Electrostatic Catalyst for Vesicle Fusion by Lowering the Hydration Energy: Arresting Vesicle Fusion by Masking PIP.

Lipids are key factors in regulating membrane fusion. Lipids are not only structural components to form membranes but also active catalysts for vesicle fusion and neurotransmitter release, which are driven by soluble -ethylmaleimide-sensitive factor attachment protein receptor (SNARE) proteins. SNARE proteins seem to be partially assembled before fusion, but the mechanisms that arrest vesicle fusion before Ca influx are still not clear.

On the Low-Pressure Hysteresis (LPH) in Gas Sorption Isotherms of Porous Carbons.

This study investigates the origin of low-pressure hysteresis (LPH) in the adsorption and desorption of three different probe molecules: carbon dioxide, nitrogen, and argon, across various adsorption temperatures (from cryogenic to room temperature), and within five different carbon materials: synthetic carbons (pristine and one post-synthetically oxidized) and natural coal. Significant attention is dedicated to elucidating LPH in oxidized samples outgassed at various temperatures (120-350 °C). Experimental results show that insufficient outgassing temperature can lead to unreliable data due to artificial LPH and significantly underestimated textural properties, primarily caused by porosity blockage from substances like moisture.

Influence of proline and hydroxyproline as antimicrobial and anticancer peptide components on the silver(I) ion activity: structural and biological evaluation with a new theoretical and experimental SAR approach.

Silver(I) complexes with proline and hydroxyproline were synthesized and structurally characterized and crystal structure analysis shows that the formulas of the compounds are {[Ag(Pro)(NO)]NO} (AgPro) (Pro = L-proline) and {[Ag(Hyp)(NO)]NO} (AgHyp) (Hyp = -4-hydroxy-L-proline). Both complexes crystallize in the monoclinic lattice with space group 2 with a carboxylate bidentate-bridging coordination mode of the organic ligands Pro and Hyp (with NH and COO groups in zwitterionic form). Both complexes have a distorted seesaw (C) geometry around one silver(I) ion with values of 58% (AgPro) and 51% (AgHyp).
