ANALYSIS OF THE RESULTS OF LABORATORY STUDIES OF ORAL FLUID AND BLOOD SERUM OF PATIENTS IN THE RETENTION PERIOD OF ORTHODONTIC TREATMENT

In the course of complex treatment of patients with dentomaxillofacial abnormalities, two periods are distinguished: the period of active apparatus treatment and the retention period (consolidation of the results of orthodontic treatment). Ensuring the stability of the treatment results in patients with abnormalities of occlusion and irregular position of the teeth depends on the correct diagnosis and treatment plan. There are special methods, confirming the effectiveness of orthodontic treatment (anthropometric, radiological, photometric). Analysis of the results of laboratory studies of oral fluid and blood serum of patients who are in the retention period allows evaluation of the effectiveness of treatment and the stability of results. Aim - studying of the results of laboratory indicators of oral fluid and blood serum of patients in the retention period of orthodontic treatment. Material and methods. The total number of examined orthodontic patients was 156. At the first stage of the study, 96 patients were examined and divided into 3 groups. At the second stage, 60 people were examined (4th group). We performed the diagnostics of gingival crevicular fluid as the most promising material in terms of diagnostic capabilities, noninvasiveness and the ease of obtaining samples, and the possibility of retaking of biomaterial. All the patients underwent the study of biochemical and immunological parameters of blood serum, oral and gingival fluid. Results. At the end of treatment, biochemical indices are aligned, and osteoblastic activity decreases, which indicates the completion of the active adjustment and normalization of bony tissue

DENTITION IN PATIENTS BEFORE AND AFTER ORTHODONTIC TREATMENT OF MALOCCLUSION CLASS III

Many scientists were engaged in the study of dentition anthropometry in patients before and after orthodontic treatment. The most common orthodontic device for the treatment of malocclusion class III is a regulator of Frenkel type III. We have proposed a new orthodontic device for the treatment of patients with malocclusion class III and premature removal of temporary molars. Aim - to compare changes of dentitions in children aged 6-12 before and after orthodontic treatment of malocclusion class III using the device of own design and regulator of Frenkel type III. Materials and methods. 110 patients at the age of 6-12 years with malocclusion class III were treated with the use of removable orthodontic curative devices. Anthropometry of dentitions was conducted before and after the treatment. Results. After applying the new diagnostic and treatment algorithm, the duration of orthodontic treatment of patients with malocclusion class III reduced by 1.3 times. The children's quality of life have improved after orthodontic treatment. Conclusion. In case of children aged 6-12 years with malocclusion class III associated with premature removal of temporary molars, it is necessary to use the device of our design. This will give the opportunity not only to fix the dento-facial abnormality, but also to restore the functions of chewing, swallowing and speech

Phytochemicals as novel agents for the induction of browning in white adipose tissue

Obesity and its associated metabolic syndrome continue to be a health epidemic in westernized societies and is catching up in the developing world. Despite such increases, little headway has been made to reverse adverse weight gain in the global population. Few medical options exist for the treatment of obesity which points to the necessity for exploration of anti-obesity therapies including pharmaceutical and nutraceutical compounds. Defects in brown adipose tissue, a major energy dissipating organ, has been identified in the obese and is hypothesized to contribute to the overall metabolic deficit observed in obesity. Not surprisingly, considerable attention has been placed on the discovery of methods to activate brown adipose tissue. A variety of plant-derived, natural compounds have shown promise to regulate brown adipose tissue activity and enhance the lipolytic and catabolic potential of white adipose tissue. Through activation of the sympathetic nervous system, thyroid hormone signaling, and transcriptional regulation of metabolism, natural compounds such as capsaicin and resveratrol may provide a relatively safe and effective option to upregulate energy expenditure. Through utilizing the energy dissipating potential of such nutraceutical compounds, the possibility exists to provide a therapeutic solution to correct the energy imbalance that underlines obesity

Pulse current treatment effect on the strength of reinforcing steel and its weld joint under impact loading

We present results of static and impact tension tests of as-received reinforcing steel specimens, specimens with weld joints in their test portion, as well as specimens pretreated by high-density pulse current. As test results demonstrate, an increased strain rate enhances strength, and the pulse current treatment greatly influences the strength and plasticity of a defect-containing weld metal under static and impact tension.Peer reviewe

Evaluation of the residual stresses in the welded joint of the header with a connecting pipe of a steam generator after additional thermomechanical treatment

Translated from Problemy Prochnosti, No. 2, pp. 74 – 79, March – April, 2010We present the results of numerical evaluation of the possibility of application of additional thermomechanical treatment to the welded joints of the headers with connecting pipes of PGV-1000 steam generators from WWER-1000 reactor units of nuclear power plants with an aim to decrease the level of stresses formed after maintenance and in the process of subsequent operation. It is shown that this type of treatment is quite promising for extending the service life of the unit.Peer reviewe

Effect of pulsed electric current treatment on corrosion of structural metals

“The original publication is available at www.springerlink.com” Copyright Springer [Full text of this article is not available in the UHRA]Results of corrosion tests of structural metals previously treated using pulsed electric current of high density are presented. According to the data obtained, the treatment substantially affects corrosion of metals. In cases of HSLA steel and 5182 aluminum alloy, an increase of corrosion resistance occurs, whereas the same treatment causes a dramatic reduction of corrosion resistance of 5754 aluminum alloy.Peer reviewe

The effect of the pulse electric current treatment on residual stresses arising in grinding

Translated from Problemy Prochnosti, No. 6, pp. 44–50, November–December, 2009We show experimentally that the passing of a pulse electric current through a strip of stainless steel with a surface layer containing grinding-induced tensile stresses substantially reduces their level. In this case, the effect of treatment is not related to the macro-heating of the strip metalPeer reviewe

Redistribution of stresses in the header-PGV-1000 steam generator connector weldment under loading after thermal treatment

Additional heating of a thickened portion of the steam generator connector during postrepair thermal treatment of the header-connector weldment leads to a decrease in residual tensile stress levels. It is shown that during hydrostatic tests performed after thermal treatment inelastic strains on the inner connector surface are reduced, which inhances the cycle life of the weldmentPeer reviewe
