Callous unemotional traits in children with disruptive behavior disorder: Predictors of developmental trajectories and adolescent outcomes.

The present study investigated trajectories of Callous Unemotional (CU) traits in youth with Disruptive Behavior Disorder diagnosis followed-up from childhood to adolescence, to explore possible predictors of these trajectories, and to individuate adolescent clinical outcomes. A sample of 59 Italian referred children with Disruptive Behavior Disorder (53 boys and 6 girls, 21 with Conduct Disorder) was followed up from childhood to adolescence. CU traits were assessed with CU-scale of the Antisocial Process Screening Device-parent report.

Plasma levels of M-CSF are increased in ANCA-associated vasculitides with active nephritis.

Anti-Neutrophil Cytoplasmic Antibodies (ANCA)-associated vasculitides (AAV) are characterized by small vessel injury and in some cases granulomatous lesions and glomerular inflammation. The pathogenic bases of these clinical phenotypes are incompletely understood, but evidence from patients with AAV and other inflammatory diseases suggest a role for monocyte/macrophages in the perpetuation of tissue injury. Macrophage colony stimulating factor (M-CSF) is a promoter of monocyte recruitment and macrophage proliferation, involved in mesangial cell proliferation and experimental nephritis development.

TGF-β Controls miR-181/ERK Regulatory Network during Retinal Axon Specification and Growth.

Retinal axon specification and growth are critically sensitive to the dosage of numerous signaling molecules and transcription factors. Subtle variations in the expression levels of key molecules may result in a variety of axonal growth anomalies. miR-181a and miR-181b are two eye-enriched microRNAs whose inactivation in medaka fish leads to alterations of the proper establishment of connectivity and function in the visual system.

A Comprehensive Map of CNS Transduction by Eight Recombinant Adeno-associated Virus Serotypes Upon Cerebrospinal Fluid Administration in Pigs.

Cerebrospinal fluid administration of recombinant adeno-associated viral (rAAV) vectors has been demonstrated to be effective in delivering therapeutic genes to the central nervous system (CNS) in different disease animal models. However, a quantitative and qualitative analysis of transduction patterns of the most promising rAAV serotypes for brain targeting in large animal models is missing. Here, we characterize distribution, transduction efficiency, and cellular targeting of rAAV serotypes 1, 2, 5, 7, 9, rh.

Molecular and Translational Classifications of DAMPs in Immunogenic Cell Death.

The immunogenicity of malignant cells has recently been acknowledged as a critical determinant of efficacy in cancer therapy. Thus, besides developing direct immunostimulatory regimens, including dendritic cell-based vaccines, checkpoint-blocking therapies, and adoptive T-cell transfer, researchers have started to focus on the overall immunobiology of neoplastic cells. It is now clear that cancer cells can succumb to some anticancer therapies by undergoing a peculiar form of cell death that is characterized by an increased immunogenic potential, owing to the emission of the so-called "damage-associated molecular patterns" (DAMPs).

Gynaecological Screening for Cervical and Vulvar Malignancies in a Cohort of Systemic Sclerosis Patients: Our Experience and Review of the Literature.

Background. Increased incidence of cancer was frequently reported in scleroderma (SSc), but no association with gynaecological malignancies was described in literature. Objectives.

TRPC6 gene variants and neuropsychiatric lupus.

Neuropsychiatric manifestations of systemic lupus erythematosus (NPSLE) influence patients' quality of life and their survival. Little is known about the pathophysiological bases of NPSLE and accordingly there are no specific therapeutic agents to be employed in this setting. Genetic research in systemic lupus erythematosus (SLE) is rapidly evolving as a tool to find clues about the pathogenic determinants of the disease and of its manifestations.

Multiplex liquid chromatography-tandem mass spectrometry for the detection of wheat, oat, barley and rye prolamins towards the assessment of gluten-free product safety.

Celiac patients should feel confident in the safety of foods labelled or expected to be gluten-free. In this context, a targeted proteomic approach based on liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) technique was proposed to assess the presence of celiotoxic cereals, namely wheat, oats, barley and rye, in raw and processed food products. To this aim, unique marker peptides were properly selected in order to distinguish between the different cereal types.

Tissue Factor Expressed by Neutrophils: Another Piece in the Vascular Inflammation Puzzle.

The transition from the classic role of neutrophils as the first line of defense of the immune system to that of physiological regulators of intravascular thrombosis took nearly three decades to emerge. This transition needed time to unravel the complex links between the mechanisms that regulate hemostasis and inflammation and the innate immune response, multicellular and multifactorial processes that interact with each other. The present review is focused on the expression of tissue factor by neutrophils, a critical event in their inflammatory and thrombotic function.

Interstitial pneumonia with autoimmune features and undifferentiated connective tissue disease: Our interdisciplinary rheumatology-pneumology experience, and review of the literature.

Background: Interstitial lung diseases (ILDs) are a heterogeneous group of disorders characterized by inflammation and/or fibrosis of the lungs, varying from idiopathic interstitial pneumonias to secondary variants, including the ILDs associated to connective tissue diseases (CTDs). In addition, a number of patients are recognized as unclassifiable ILD (U-ILD), because of the inability to reach a definite diagnosis; some of them show autoimmune manifestations not fulfilling the classification criteria of a given CTD. The term interstitial pneumonia with autoimmune features (IPAF) has been recently proposed for this particular ILD subset.

A trans-Regulatory Code for the Forebrain Expression of Six3.2 in the Medaka Fish.

A well integrated and hierarchically organized gene regulatory network is responsible for the progressive specification of the forebrain. The transcription factor Six3 is one of the central components of this network. As such, Six3 regulates several components of the network, but its upstream regulators are still poorly characterized.

Cellulose degrading bacteria isolated from industrial samples and the gut of native insects from Northwest of Argentina.

The raw materials used to produce bioethanol mostly are food crops, which has led to conflicts on food security. It is, therefore, recommended the gradual replacement for second generation substrates such as lignocellulosic materials. Herein, cellulolytic bacteria were isolated from the gut content of native larvae from Lepidoptera, Coleoptera, and adults of Isoptera.

Are atopy and eosinophilic bronchial inflammation associated with relapsing forms of chronic rhinosinusitis with nasal polyps?

Background: The aetiopathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP) is still unknown. The role of atopy and the concept of united airways in such patients are still a matter of debate. In this pilot study we aimed at evaluating the degree of eosinophilic inflammation and the frequency of atopy in a cohort of CRSwNP patients candidate for Functional Endoscopic Sinus Surgery (FESS) and assessing the association between these factors and relapsing forms of CRSwNP.

Beta-adducin and sodium-calcium exchanger 1 gene variants are associated with systemic lupus erythematosus and lupus nephritis.

Genetic research in systemic lupus erythematosus (SLE) is rapidly developing, and numerous sets of genes are being associated with specific clinical subphenotypes in the setting of SLE. On the other hand, basic science studies are revealing strong connections between salt-water balance and inflammation. The aim of this study was to evaluate whether variants of genes known to influence the individual susceptibility to hypertension also influence the renal function in a cohort of SLE patients with and without lupus nephritis (LN).

FOXP3+ T Cells Recruited to Sites of Sterile Skeletal Muscle Injury Regulate the Fate of Satellite Cells and Guide Effective Tissue Regeneration.

Muscle injury induces a classical inflammatory response in which cells of the innate immune system rapidly invade the tissue. Macrophages are prominently involved in this response and required for proper healing, as they are known to be important for clearing cellular debris and supporting satellite cell differentiation. Here, we sought to assess the role of the adaptive immune system in muscle regeneration after acute damage.

Evaluation of Improvement in Externalizing Behaviors and Callous-Unemotional Traits in Children with Disruptive Behavior Disorder: A 1-Year Follow Up Clinic-Based Study.

Multi-component interventions based on cognitive behavioral principles and practices have been found effective in reducing behavioral problems in children with disruptive behavior disorders (oppositional defiant disorder and conduct disorder). However, it is still unclear if these interventions can affect children's callous-unemotional traits, which are predictive of subsequent antisocial behavior. Furthermore, it could be important to identify empirically supported treatment protocols for specific disorders addressed by child mental health services.

Altered chromogranin A circulating levels in Meniere's disease.

Objectives: Meniere's disease (MD) is an inner ear disorder characterized by episodic vertigo, ear fullness, and hearing loss; usually vertigo attacks cluster in specific period. We studied in MD patients the circulating levels of chromogranin A (CgA) and vasostatin-1 (VS-1), secreted by the neuroendocrine system and involved in the regulation of the endothelial barrier function.

Methods: Serum levels were assessed in 37 MD patients and 36 controls.

Parietal and intravascular innate mechanisms of vascular inflammation.

Sustained inflammation of the vessel walls occurs in a large number of systemic diseases (ranging from atherosclerosis to systemic vasculitides, thrombotic microangiopathies and connective tissue diseases), which are ultimately characterized by ischemia and end-organ failure. Cellular and humoral innate immunity contribute to a common pathogenic background and comprise several potential targets for therapeutic intervention. Here we discuss some recent advances in the effector and regulatory action of neutrophils and in the outcome of their interaction with circulating platelets.

Fat deposition and accumulation in the damaged and inflamed skeletal muscle: cellular and molecular players.

The skeletal muscle has the capacity to repair damage by the activation and differentiation of fiber sub-laminar satellite cells. Regeneration impairment due to reduced satellite cells number and/or functional capacity leads to fiber substitution with ectopic tissues including fat and fibrous tissue and to the loss of muscle functions. Muscle mesenchymal cells that in physiological conditions sustain or directly contribute to regeneration differentiate in adipocytes in patients with persistent damage and inflammation of the skeletal muscle.

Prevalence and evolution of scleroderma pattern at nailfold videocapillaroscopy in systemic sclerosis patients: Clinical and prognostic implications.

Background: Microvascular involvement plays a decisive role in systemic sclerosis (SSc) pathogenesis occurring early in the course of the disease. Microangiopathy is responsible of important clinical manifestations, such as Raynaud's phenomenon, digital ulceration, and pulmonary arterial hypertension. Typical microvascular alterations, called scleroderma pattern, are detectable at nailfold capillaroscopy in a significant percentage of SSc patients; however its prevalence is highly variable in published studies.

miR-181a/b control the assembly of visual circuitry by regulating retinal axon specification and growth.

Connectivity and function of neuronal circuitry require the correct specification and growth of axons and dendrites. Here, we identify the microRNAs miR-181a and miR-181b as key regulators of retinal axon specification and growth. Loss of miR-181a/b in medaka fish (Oryzias latipes) failed to consolidate amacrine cell processes into axons and delayed the growth of retinal ganglion cell (RGC) axons.

Predictive value of isolated DLCO reduction in systemic sclerosis patients without cardio-pulmonary involvement at baseline.

Impaired diffusing capacity of the lung for carbon monoxide (DLCO) was frequently observed in systemic sclerosis (SSc) patients, generally related to the presence of interstitial lung disease (ILD) and/or pulmonary arterial hypertension (PAH). However, in clinical practice abnormally low DLCO values may be found also in the absence of these SSc complications. The objective was to investigate the prospective clinical relevance of isolated DLCO reduction at baseline in SSc patients.

Cryoglobulinemic vasculitis and skin ulcers. Our therapeutic strategy and review of the literature.

Objective: Cryoglobulinemic vasculitis (CV) involving small- and medium-sized vessels is very frequently associated with hepatitis C virus and may be responsible for multiple organ involvement and skin ulcers (SU). Skin ulcers are often non-healing cutaneous lesions, possibly complicated by local infection and gangrene; they may severely affect the patients׳ quality of life and the overall prognosis. Therefore, the treatment of cryoglobulinemic SU is particularly challenging in the clinical practice.
