Ficolin activation as a potential biomarker of the severity of schizophrenia.

Several studies have examined the complement system in schizophrenia, suggesting an involvement of the lectin pathway. We analyzed 49 patients with schizophrenia and explored the association between psychopathology of schizophrenia and complement component 3 (C3) serum levels, C-reactive protein (CRP) serum levels, ficolin activation, and mannose-binding lectin (MBL) activation. In the multiple regression analysis, a negative association was observed between the Positive and Negative Syndrome Scale (PANSS) total score and ficolin activation.

[Beta 2-adrenergic receptor gene association with overweight and asthma in children and adolescents and its relationship with physical fitness].

Objective:: To investigate the association of and polymorphisms of β2-adrenergic receptor gene () with the occurrence of asthma and overweight and the gene's influence on anthropometric, clinic, biochemical and physical fitness variables in children and adolescents.

Methods:: Subjects were evaluated for allelic frequencies of the β2-adrenergic receptor gene, height, weight, body mass index (BMI), BMI -score, waist circumference (WC), pubertal stage, resting heart rate (HRres), blood pressure (BP), total cholesterol (TC), glucose, insulin, high density lipoprotein (HDL-C), low density lipoprotein (LDL-C), triglyceride (TG), Homeostasis Metabolic Assessment (HOMA2-IR), Quantitative Insulin Sensitivity Check Index (QUICKI) and maximal oxygen uptake (VO). The participants were divided in four groups: overweight asthmatic (=39), overweight non-asthmatic (=115), normal weight asthmatic (=12), and normal weight non-asthmatic (=40).
