Obesity is reckoned as one of the civilization diseases, posing a considerable global health issue. Evidence points towards a contribution of multitude immune cell populations in obesity pathomechanism and the development of chronic low-grade inflammation in the expanded adipose tissue. Notably, adipose tissue is a reservoir of mast cells which number in individuals with obesity particularly increased. Some of them tend to degranulation what generate secretion of strong pro-inflammatory and regulatory mediators, as well as cytokines/chemokines...

Suicide is one of the most important public health problems. There was an association between suicide and several factors such as psychiatric diseases and psychological characteristics, somatic illness, cultural, socioeconomic, familial, occupational and individual risk factors. Also, high altitude and climatic factors including high temperature, cloudiness, more sunshine and low rainfalls were defined as some of these risk factors in the literature. In this study, we aimed to investigate correlation between suicide rates and altitudes of all cities in Turkey and between suicide rates and climatic factors including Rainfall Activity Index, Winter Mean Temperatures, Summer Mean Temperatures and Temperature Difference between January and July previously defined by several authors in the broad series in Turkey...

RATIONALE: A novel benzimidazole compound ZLN005 was previously identified as a transcriptional activator of peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) in certain metabolic tissues. Upregulation of PGC-1α by ZLN005 has been shown to have beneficial effect in a diabetic mouse model and in a coronary artery disease model in vitro. ZLN005 could also have therapeutic potential in neurodegenerative diseases involving down-regulation of PGC-1α. Given the phenotypic efficacy of ZLN005 in several animal models of human disease, its metabolic profile was investigated to guide the development of novel therapeutics using ZLN005 as the lead compound...

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a common disease with an uncertain pathophysiology. It is characterized by polyps rich in eosinophils, with an activation status already investigated at the tissue level. In a group of CRSwNP patients, we assessed the activation status of circulating eosinophils in the blood before migration into tissues. METHODS: Thirteen patients with CRSwNP and 16 healthy volunteers were enrolled. Several biologic parameters were studied: blood count of eosinophils; plasma eosinophil cationic protein; oxidative metabolism by chemiluminescence at baseline or when activated by phorbol 12-myristate 13-acetate or platelet-activating factor, with or without interleukin-5 (IL-5); percent of granulosar cells; and mean fluorescence intensity (MFI) by flow cytometry...

Introduction The identification of patients with severe asthma who will benefit from a personalized management approach remains an unmet need. Interleukin-13 (IL-13) is a cytokine possessing a significant role in asthma pathogenesis and progression of disease. Humanised monoclonal antibodies against IL-13 and IL-13 and IL-4 receptors are mainly proposed as add-on therapy in patients with TH2-high inflammation with uncontrolled asthma despite maximum therapy. Areas covered The role of IL-13 in airway inflammation in severe asthma, the targeted anti-IL-13 therapies and biomarkers that predict response to anti-IL-13 treatment are discussed...

Psoriasis is a multi-systemic chronic inflammatory disease that affects about 1.5-3% of the general population, of which almost 20% suffer from a moderate-severe form. Those patients can be treated with a systemic agent, and, in case of scarce response or contraindications, they may require a biologic therapy, such as tumor necrosis factor or interleukin-12/23 inhibitors. When also those agents fail, clinicians face a true therapeutic challenge. We report a case series of multi-failure 16 patients, successfully treated with secukinumab, a fully human monoclonal antibody that selectively neutralizes interleukin-17A, recently approved for the treatment of plaque psoriasis, psoriatic arthritis and ankylosing spondylitis...

Human neurodevelopmental disorders (NDDs) involve mutations in hundreds of individual genes, with over-representation in genes encoding proteins that alter chromatin structure to modulate gene expression. Here, we highlight efforts to model these NDDs through in vitro differentiation of patient-specific induced pluripotent stem cells into neurons. We discuss how epigenetic regulation controls normal cortical development, how mutations in several classes of epigenetic regulators contribute to NDDs, and approaches for modeling cortical development and function using both directed differentiation and formation of cerebral organoids...

A novel electrokinetic preconcentration approach, so-called multiple pressure-assisted large-volume sample stacking with an electroosmotic flow pump (M-PA-LVSEP), was developed to allow in-capillary enrichment and separation of analytes from unlimited sample volumes. With this approach, the inherent limitation of in-capillary electrokinetic preconcentrations to the separation capillary volume can be overcome. The M-PA-LVSEP protocol relies on repeated cycles of pressure-assisted electroosmotic pumping and injection of extremely large sample volumes for analyte stacking and sample matrix removal...

Cancer is a major leading cause of disease-related death in the world. The severe impact of cancer can be attributed to poor understanding of the mechanisms involved in earliest steps of the metastatic cascade, specifically invasion into the surrounding stroma and intravasation into the blood capillaries. However, conducting integrated biological studies of invasion and intravasation have been challenging, within in vivo models and traditional in vitro assay, due to difficulties in establishing a precise tumor microenvironment...

Carotid artery disease (CAD) is a common cause of ischemic stroke with high rates of recurrence. Carotid endarterectomy (CEA) or carotid artery stenting (CAS) are highly recommended for the secondary prevention of symptomatic CAD during the first 14 days following the index event of transient ischemic attack or minor stroke. CEA or CAS may also be offered in selected cases with severe asymptomatic stenosis. Herein, we review the utility of neurosonology in the diagnosis and pre-/peri-interventional assessment of CAD patients who undergo carotid revascularization procedures...

BACKGROUND: Myasthenia gravis (MG) is an autoimmune disorder of the neuromuscular junction in which a clinical diagnosis may be confirmed with serological testing. The most common autoantibodies used to support a diagnosis of MG are anti-acetylcholine receptor antibodies and anti-muscle-specific tyrosine kinase antibodies. In cases in which both of these autoantibodies are negative (termed double-seronegative [dSNMG]), other autoantibodies such as low-density lipoprotein receptor-related protein 4 (LRP4) may be used to aid in diagnosis...
