Regression models in the assessment of the relationship between body posture in the sagittal plane and SEMG of the spine rectifier in children at a younger school age

The aim of the study was to create regression models for the analysis of the relationship between posture defects in the sagittal plane and SEMG of the spine rectifier in children with scoliotic lesions. The shape of the spine was assessed using the optoelectronic method Diers formetric III 4D. The SEMG analysis was performed using the Noraxon TeleMyo DTS 12 channel camera. The research was carried out in 2017 at the Posturology Laboratory at the Faculty of Medicine and Health Sciences of UJK in Kielce. The most important and statistically significant predictor of the body posture in the sagittal plane and the frequency of the ridge extensor examined in various positions in the group of scoliotic postures turned out to be the variable lower limb up the right breast segment (p = 0.01). In the case of the SEMG amplitude, the most important and statistically significant predictors in the group of scoliotic attitudes turned out to be variable lower limbs upward lumbar segment right side (p = 0.02) and standing position lumbar segment left side (p = 0.03). The SEMG test enables the control of muscle balance and allows to avoid the improper deepening of muscle asymmetry, resulting in the stimulation of disturbing forces

Vascular effects of advanced glycation end-products : content of immunohistochemically detected AGEs in radial artery samples as a predictor for arterial calcification and cardiovascular risk in asymptomatic patients with chronic kidney disease

Objectives. Our aim was to determine whether vascular deposition of advanced glycation end-products (AGEs) is associated with arterial calcification and cardiovascular mortality in chronic kidney disease (CKD) patients and to assess the relationships between vascular content of AGEs and selected clinical and biochemical parameters. Materials and Methods. The study comprised 54 CKD patients (33 hemodialyzed, 21 predialyzed). Examined parameters included BMI, incidence of diabetes, plasma fasting glucose, AGEs, soluble receptor for AGEs and 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging, serum C-reactive protein (hsCRP), plasminogen activator inhibitor-1 (PAI-1), and fetuin-A. Fragments of radial artery obtained during creation of hemodialysis access were stained for calcifications using alizarin red. AGEs deposits were identified immunohistochemically and their relative content was quantified. Results. Vascular content of AGEs was positively correlated with BMI, hsCRP, fetuin-A, PAI-1, and DPPH scavenging in simple regression; only fetuin-A was an independent predictor in multiple regression.There was a significant positive trend in the intensity of AGEs immunostaining among patients with grades 1, 2, and 3 calcifications. AGEs immunostaining intensity predicted 3-year cardiovascular mortality irrespective of patient’s age. Conclusions. The present study demonstrates an involvement of AGEs in the development of medial arterial calcification and the impact of arterial AGE deposition on cardiovascular mortality in CKD patient

Multi-Criterial Analysis Tool to Design a Hybrid Ballistic Plate

The presented research focuses on the concept of an advanced ballistic personal protection design, taking into account safety as well as performance requirements. The application of the multi-criterial analysis (MCA) allows for a comprehensive comparison of all the properties of materials and to select the optimal personal ballistic protection system, considering their mechanical and ballistic properties. The newly developed hybrid ballistic composites, consisting of two or three various components (variations of ballistic and/or non-ballistic textiles; hybrid ballistic plates—HBP), were evaluated via a multi-criterial analysis that considered a wide range of properties, describing behavior and safety usage, as well as the economical aspect of their fabrication
