Connections and Unmet Needs: Severe Asthma Biologics and Osteoporosis.

Asthma is a chronic inflammatory disease with the main anti-inflammatory drugs for better disease control being steroids or corticosteroids. The use of steroids in asthma patients, in particular in uncontrolled asthma patients, is associated with an increased risk of osteoporosis and fragility fractures. A single oral corticosteroid course increases the risk of osteoporosis and the continual use of inhaled corticosteroids is correlated over time to an increased risk for both bone conditions.

Exploring the Hearing Improvement and Parental Stress in Children with Hearing Loss Using Hearing Aids or Cochlear Implants.

This study aims to describe the stress levels experienced by parents of children with hearing loss who use conventional hearing aids or cochlear implants, and to assess the correlation between parental stress and the auditory skills acquired by the children. The study was conducted at the Policlinic "Gaetano Martino" in Messina, evaluating data from 42 pairs of parents of children using hearing aids or cochlear implants. Parents completed the LittlEARS Auditory Questionnaire (LEAQ) and the Parental Stress Scale (PSS) 18 months after the initial device (hearing aid or cochlear implant) had been activated.

Skin Tape Stripping Reveals Distinct Biomarker Profiles in Chronic Hand Eczema of Patients With and Without Comorbid Atopic Dermatitis.

Introduction: Chronic hand eczema (CHE) is a highly prevalent inflammatory skin condition which is often resistant to conventional treatments. Molecular insights of CHE remain limited. Tape stripping combined with high-throughput RNA sequencing can now provide a better insight into CHE pathogenesis in a minimally invasive fashion.

Vibrational fiber photometry: label-free and reporter-free minimally invasive Raman spectroscopy deep in the mouse brain.

Optical approaches to monitor neural activity are transforming neuroscience, owing to a fast-evolving palette of genetically encoded molecular reporters. However, the field still requires robust and label-free technologies to monitor the multifaceted biomolecular changes accompanying brain development, aging or disease. Here, we have developed vibrational fiber photometry as a low-invasive method for label-free monitoring of the biomolecular content of arbitrarily deep regions of the mouse brain in vivo through spontaneous Raman spectroscopy.

MARC1 downregulation reduces hepatocyte lipid content by increasing beta-oxidation.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a global epidemic. MASLD has a strong genetic component, and a common missense variant (rs2642438) in the mitochondrial amidoxime-reducing component 1 (MARC1) gene confers protection against its onset and severity. However, there are contrasting results regarding the mechanisms entangling this protection.

β-Carotene Impacts the Liver MicroRNA Profile in a Sex-Specific Manner in Mouse Offspring of Western Diet-Fed Mothers: Results from Microarray Analysis by Direct Hybridization.

Maternal unbalanced diets cause adverse metabolic programming and affect the offspring's liver microRNA (miRNA) profile. The liver is a site of β-carotene (BC) metabolism and a target of BC action. We studied the interaction of maternal Western diet (WD) and early-life BC supplementation on the epigenetic remodeling of offspring's liver microRNAs.

Omega-3 and Sports: Focus on Inflammation.

Inflammation is expected in sports, especially when practiced at a high level. The human body is pushed toward its limit, and this is perceived as a "stressogenic agent". Athletes, especially elite ones, desire it because their bodies can react with super-compensation, i.

Cognitive Impairment and Synaptic Dysfunction in Cardiovascular Disorders: The New Frontiers of the Heart-Brain Axis.

Within the central nervous system, synaptic plasticity, fundamental to processes like learning and memory, is largely driven by activity-dependent changes in synaptic strength. This plasticity often manifests as long-term potentiation (LTP) and long-term depression (LTD), which are bidirectional modulations of synaptic efficacy. Strong epidemiological and experimental evidence show that the heart-brain axis could be severely compromised by both neurological and cardiovascular disorders.

Apolipoprotein E and Alzheimer's Disease in Italian Population: Systematic Review and Meta-Analysis.

This meta-analysis with a systematic review was undertaken to assess the association between allelic genotypes and the risk of Alzheimer's disease (AD) in the Italian population. The Web of Science, PubMed, and Scopus databases were searched until 15 November 2023. The odds ratio (OR) with a 95% confidence interval (CI) was calculated using fixed and random effect models, depending on the I statistic value.

Pharmacogenomics and pediatric drug development: science and political power. A narrative review.

Introduction: Pharmacogenomics (PGx) investigates how genomes control enzyme expression. Developmental pharmacology (DP) describes the temporal sequence of enzymes impacting absorption, distribution, metabolism, and excretion (ADME) of food and drugs.

Areas Covered: US and European Union (EU) legislation facilitate and/or enforce pediatric studies for all new drugs, called overall 'pediatric drug development' (PDD).

Lipid droplets and small extracellular vesicles: More than two independent entities.

Despite increasing knowledge about small extracellular vesicle (sEV) composition and functions in cell-cell communication, the mechanism behind their biogenesis remains unclear. Here, we reveal for the first time that sEV biogenesis and release into the microenvironment are tightly connected with another important organelle, Lipid Droplets (LDs). The correlation was observed in several human cancer cell lines as well as patient-derived colorectal cancer stem cells (CR-CSCs).

The Unexpected Role of the Endothelial Nitric Oxide Synthase at the Neurovascular Unit: Beyond the Regulation of Cerebral Blood Flow.

Nitric oxide (NO) is a highly versatile gasotransmitter that has first been shown to regulate cardiovascular function and then to exert tight control over a much broader range of processes, including neurotransmitter release, neuronal excitability, and synaptic plasticity. Endothelial NO synthase (eNOS) is usually far from the mind of synaptic neurophysiologists, who have focused most of their attention on neuronal NO synthase (nNOS) as the primary source of NO at the neurovascular unit (NVU). Nevertheless, the available evidence suggests that eNOS could also contribute to generating the burst of NO that, serving as volume intercellular messenger, is produced in response to neuronal activity in the brain parenchyma.

Differential Digestive Stability of Food-Derived microRNAs: The Case of miR-30c-5p and miR-92a-3p in Polyfloral Honey.

Dietary microRNAs (miRs) represent a new area in food science. Although they have been found in many foods, including honey, more research is needed about their stability and fate during digestion. Hence, this study aimed to analyze the digestive stability of two selected miRs in honey.

Lysosomal TRPML1 triggers global Ca signals and nitric oxide release in human cerebrovascular endothelial cells.

Lysosomal Ca signaling is emerging as a crucial regulator of endothelial Ca dynamics. Ca release from the acidic vesicles in response to extracellular stimulation is usually promoted Two Pore Channels (TPCs) and is amplified by endoplasmic reticulum (ER)-embedded inositol-1,3,4-trisphosphate (InsP) receptors and ryanodine receptors. Emerging evidence suggests that sub-cellular Ca signals in vascular endothelial cells can also be generated by the Transient Receptor Potential Mucolipin 1 channel (TRPML1) channel, which controls vesicle trafficking, autophagy and gene expression.

MicroRNA Monitoring in Human Alveolar Macrophages from Patients with Smoking-Related Lung Diseases: A Preliminary Study.

Chronic obstructive pulmonary disease (COPD) is a progressive lung disease that is commonly considered to be a potent driver of non-small cell lung cancer (NSCLC) development and related mortality. A growing body of evidence supports a role of the immune system, mainly played by alveolar macrophages (AMs), in key axes regulating the development of COPD or NSCLC phenotypes in response to harmful agents. MicroRNAs (miRNAs) are small non-coding RNAs that influence most biological processes and interfere with several regulatory pathways.

The role of elasticity on adhesion and clustering of neurons on soft surfaces.

The question of whether material stiffness enhances cell adhesion and clustering is still open to debate. Results from the literature are seemingly contradictory, with some reports illustrating that adhesion increases with surface stiffness and others suggesting that the performance of a system of cells is curbed by high values of elasticity. To address the role of elasticity as a regulator in neuronal cell adhesion and clustering, we investigated the topological characteristics of networks of neurons on polydimethylsiloxane (PDMS) surfaces - with values of elasticity (E) varying in the 0.

Family religiosity and climate: the protective role of personal interiorized religiosity in deviance propensity among justice-involved juveniles.

According to the literature, religious commitment could be a protective factor against dangerous behaviors, such as criminal offending, unsafe sex, and substance use. Our study aims to investigate the influence of Family Religiosity and climate on anger dysregulation and deviance propensity in a sample of 214 justice-involved boys from Italian Youth Detention Centers (range 14-25). The sample was divided into religious ( = 102) and non-religious ( = 112) justice-involved juveniles.

FAM19A4 and hsa-miR124-2 Double Methylation as Screening for ASC-H- and CIN1 HPV-Positive Women.

The DNA methylation levels of host cell genes increase with the severity of the cervical intraepithelial neoplasia (CIN) grade and are very high in cervical cancer. Our study aims to evaluate FAM19A4 and hsa-miR124-2 methylation in Atypical Squamous cells with high-grade squamous intraepithelial lesions (ASC-H) and in CIN1, defined as low-grade squamous intraepithelial lesions (LSILs) by the Bethesda classification, as possible early warning biomarkers for managing women with high-risk HPV infections (hrHPV). FAM19A4 and hsa-miR124-2 methylation tests were conducted on fifty-six cervical screening samples from a subset of women aged 30-64 years old.

Determination of AGE-CML Level in Commercially Available Sports Bar in Italy.

Introduction: The process of bar creation involves improving the texture of the product to increase its palatability, which can be further induced by various physical or chemical changes during storage, such as sugar crystallization and molecular migrations in which Maillard's reaction occurs, forming the N-epsilon- (carboxymethyl) lysine (CML) adduct. In this study, we aimed to assess (the CML) adduct used in commercial bars today as meal substitutes or for athletic or sports purposes. The adduct CML is an advanced glycation end-product (AGEs) found in the human body (serum) and foods.
