Normative percentile values for the TGMD-3 for Italian children aged 3-11+years.

Objectives: Sufficient gross motor skill proficiency is an essential prerequisite for the successful performance of sport-specific skills and physical activities. The Test of Gross Motor Development is the most common tool for assessing motor skills in paediatric populations, however, there is a lack of 'normative' data available against which children's scores can be compared. Normative data would enable the comparison of an individual's motor development to age-standardised norms.

Plasmon-Enhanced Luminescence of Gold Nanoclusters by Using Silver and Gold Metal Nanostructures.

Plasmonic materials can be utilized as effective platforms to enhance luminescent signals of luminescent metal nanoclusters (LMNCs). Both surface enhanced fluorescence (SEF) and shell-isolated nanoparticle-enhanced fluorescence (SHINEF) strategies take advantage of the localized and increased external electric field created around the plasmonic metal surface when excited at or near their characteristic plasmonic resonance. In this context, we present an experimental and computational study of different plasmonic composites, (Ag) Ag@SiO and (Au) Au@SiO nanoparticles, which were used to enhance the luminescent signal of Au nanoclusters coated with glutathione (GSH) molecule (AuGSH NCs).

On the Role of a Polymer Matrix in Enhancing Energy Transfer Efficiency Using Coumarin 6 and Rhodamine B as Donor and Acceptor Pairs.

This study investigates the critical role of polymer matrices in optimizing luminescence and energy transfer, utilizing the commercial dyes Coumarin 6 (C6) and Rhodamine B (RhB) as a donor-acceptor pair. Solution-phase experiments revealed a dependence of energy transfer efficiency on solvent dielectric constant. Furthermore, embedding the dyes within Poly(methyl methacrylate) (PMMA) or Poly(vinyl butyral) (PVB) matrices significantly enhance energy transfer due to increased molecular proximity.

Proteome Reprogramming and Acquired Stress Tolerance in Potato Cells Exposed to Acute or Stepwise Water Deficit.

Water deficit negatively impacts crop productivity and quality. Plants face these challenges by adjusting biological processes and molecular functions according to the intensity and duration of the stress. The cultivated potato (Solanum tuberosum) is considered sensitive to water deficit, thus breeding efforts are needed to enhance its resilience.

Multi-modal immune dynamics of pre-COVID-19 Kawasaki Disease following intravenous immunoglobulin.

Despite progress, the molecular mechanisms underlying Kawasaki Disease (KD) and intravenous immunoglobulin's (IVIG) ability to mitigate the inflammatory process remain poorly understood. To characterize this condition, plasma proteomic profiles, flow cytometry, and gene expression of T cell subsets were investigated in longitudinal samples from KD patients and compared with two control groups. Systems-level analysis of samples in the acute phase revealed distinctive inflammatory features of KD, involving mainly Th-1 and Th-17 mediators and unveiled a potential disease severity signature.

Thus, a comparative overview of the state of the art in the two pre-pandemic decades that can facilitate an understanding of the different territorial realities and training needs to be conducted, considering the different cultural situations. A scoping review was conducted by analysing a series of studies published between 1990 and 2022, including only those studies that collected data in the pre-pandemic period.

A computational model of Pseudomonas syringae metabolism unveils a role for branched-chain amino acids in Arabidopsis leaf colonization.

Bacterial pathogens adapt their metabolism to the plant environment to successfully colonize their hosts. In our efforts to uncover the metabolic pathways that contribute to the colonization of Arabidopsis thaliana leaves by Pseudomonas syringae pv tomato DC3000 (Pst DC3000), we created iPst19, an ensemble of 100 genome-scale network reconstructions of Pst DC3000 metabolism. We developed a novel approach for gene essentiality screens, leveraging the predictive power of iPst19 to identify core and ancillary condition-specific essential genes.

Antioxidant and photoprotective role of latex C-serum from during 15-week UVB irradiation in male hairless SKH-1 mice.

It is known that UVB radiation induces several adverse skin alterations starting from simple photoaging to skin cancer. In addition, it was demonstrated that reactive oxygen species (ROS) were found to be related to cancer development and progression. The aim of study was to examine whether male hairless (SKH-1) mice () that were subchronically exposed to UVB radiation presented with actinic keratosis (AK) and squamous cell carcinoma lesions, and that treatment with latex C-serum cream significantly prevented abnormal skin development.

Thrombotic Features as the Primary Cause of SARS-CoV-2 Related Acute Abdomen in Children.

Objectives: We performed a retrospective case control study to evaluate the histological characteristics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positive pediatric patients undergoing laparoscopic exploration for acute abdomen symptoms. To our knowledge this is the first study that analyzes histopathological characteristics of abdominal tissues in SARS-CoV-2 children.

Synthesis of new antiproliferative 1,3,4-substituted-pyrrolo[3,2-c]quinoline derivatives, biological and in silico insights.

A series of biologically unexplored substituted 1,3,4-subtituted-pyrrolo[3,2-c]quinoline derivatives (PQs) was evaluated against a panel of about 60 tumor cells (NCI). Based on the preliminary antiproliferative data, the optimizations efforts permitted us to design and synthesize a new series of derivatives allowing us to individuate a promising hit (4g). The insertion of a 4-benzo[d] [1,3]dioxol-5-yl moiety on increased and extended the activity towards five panel tumor cell lines such as leukemia, CNS, melanoma, renal and breast cancer, reaching IG in the low μM range.

Effects of condensates from volcanic fumaroles and cigarette smoke extracts on airway epithelial cells.

The impact of volcanic airborne products on airway epithelium homeostasis is largely unknown. This study assessed the effects of volcanic Fumarole Condensates (FC) alone or combined with Cigarette Smoke Extracts (CSE) on airway epithelial cells (16HBE and A549). Chemical composition of FC was analyzed by gas chromatography and HPLC.

Elicitor-induced plant immunity relies on amino acids accumulation to delay the onset of bacterial virulence.

Plant immunity relies on the perception of microbe-associated molecular patterns (MAMPs) from invading microbes to induce defense responses that suppress attempted infections. It has been proposed that MAMP-triggered immunity (MTI) suppresses bacterial infections by suppressing the onset of bacterial virulence. However, the mechanisms by which plants exert this action are poorly understood.

The Arabidopsis LHT1 Amino Acid Transporter Contributes to -Mediated Plant Growth Promotion by Modulating Bacterial Metabolism in the Rhizosphere.

The root microbiome structure ensures optimal plant host health and fitness, and it is, at least in part, defined by the plant genotype. It is well documented that root-secreted amino acids promote microbial chemotaxis and growth in the rhizosphere. However, whether the plant-mediated re-uptake of amino acids contributes to maintaining optimal levels of amino acids in the root exudates, and, in turn, microbial growth and metabolism, remains to be established.

Mesoporous Silica Particles Functionalized with Newly Extracted Fish Oil (Omeg@Silica) Reducing IL-8 Counteract Cell Migration in NSCLC Cell Lines.

Lung cancer is one of the leading forms of cancer in developed countries. Interleukin-8 (IL-8), a pro-inflammatory cytokine, exerts relevant effects in cancer growth and progression, including angiogenesis and metastasis in lung cancer. Mesoporous silica particles, functionalized with newly extracted fish oil (Omeg@Silica), are more effective than the fish oil alone in anti-proliferative and pro-apoptotic effects in non-small cell lung cancer (NSCLC) cell lines.

MIS-C: A COVID-19-as sociated condition between hypoimmunity and hyperimmunity.

Multisystem inflammatory syndrome in children (MIS-C) is a rare, severe complication of COVID-19. A better knowledge of immunological, cellular, and genetic characteristics of MIS-C could help better understand the pathogenesis of the disease and contribute to identifying specific diagnostic biomarkers and develop targeted therapies. We studied 37 MIS-C children at hospital admission and 24 healthy controls analyzing serum cytokines (IFN-α, IFN-β, IFN-γ, IL-6, IL-10, IL-17A, IL-12p70 and TNF), lymphocyte populations by flow cytometry and 386 genes related to autoimmune diseases, autoinflammation and primary immunodeficiencies by NGS.

New Onset Cardiac Murmur and Exertional Dyspnea in an Apparently Healthy Child: A Rare Localization of Obstructive Myxoma in the Right Ventricle Outflow Tract without Pulmonary Embolization-A Case Report and Literature Review.

Myxomas are slowly growing benign neoplasms which are rare in children. Up to 80% can be located in the left atrium and generate symptoms such as embolism, cardiac failure, fever and weight loss. Rarely, myxomas can be detected in the right ventricle outflow tract, causing arrhythmias, pulmonary emboli and sudden death.

Immunophenotyping of peripheral blood cells allows to discriminate MIS-C and Kawasaki disease.

Background: The pathogenesis of the novel described multisystem inflammatory syndrome in children (MIS-C) and Kawasaki disease (KD) is still debated as it is not clear if they are the same or different nosological entities. However, for both the diseases a rapid and unequivocal diagnosis is mandatory to start the therapy before the onset of severe complications. In this study, we aimed to evaluate the white cell populations in MIS-C and KD as potential markers to discriminate between the two diseases.

Use of a modified SIR-V model to quantify the effect of vaccination strategies on hospital demand during the Covid-19 pandemic.

A novel compartmental model that includes vaccination strategy, permanence in hospital wards and tracing of infected individuals has been implemented to forecast hospital overload caused by COVID-19 pandemics in Italy. The model parameters were calibrated according to available data on cases, hospital admissions, and number of deaths in Italy during the second wave, and were validated in the timeframe corresponding to the first successive wave where vaccination campaign was fully operational. This model allowed quantifying the decrease of hospital demand in Italy associated with the vaccination campaign.

Centre of pressure parameters for the assessment of biomechanical risk in fatiguing frequency-dependent lifting activities.

Lifting tasks, among manual material handling activities, are those mainly associated with low back pain. In recent years, several instrumental-based tools were developed to quantitatively assess the biomechanical risk during lifting activities. In this study, parameters related to balance and extracted from the Centre of Pressure (CoP) data series are studied in fatiguing frequency-dependent lifting activities to: i) explore the possibility of classifying people with LBP and asymptomatic people during the execution of task; ii) examine the assessment of the risk levels associated with repetitive lifting activities, iii) enhance current understanding of postural control strategies during lifting tasks.
