A P Spitsin, T A Pershina, Y K Tsarev
Central hemodynamics and vegetative regulation of heart rhythms in males depending on age were studied. To evaluate and estimate vegetative regulation a method of variative pulsometry was used. It was used on the basis of analysis of variable heart rhythm (temporary and spectral). Certain tendencies of changes of central hemodynamics and indicators of variable heart rhythm in different age periods were revealed. SDNN, RMSSD and power in HF-range decreased. Baevsky's index of tension and VLF-output increased...

PURPOSE: We implemented magnetic resonance-guided breath-hold stereotactic body radiation therapy in combination with visual feedback using the MRIdian system. Both accuracy of gated delivery and reproducibility of tumor positions were studied. METHODS AND MATERIALS: Tumor tracking is realized through repeated magnetic resonance imaging in a single sagittal plane at 4 frames per second with deformable image registration. An in-room monitor allowed visualization of the tracked gross tumor volume (GTV) contour and the planning target volume (PTV) (GTV + 3 mm), which was the gating boundary...

Background: In practice, the dose perturbation effect of head and neck immobilization devices is often overlooked in intensity-modulated radiation therapy (IMRT) for nasopharyngeal carcinoma (NPC). Purpose of this study is to verify and analyze the dosimetric effect of head and neck immobilization devices on NPC multi-field IMRT. Methods: Ten patients with nasopharyngeal carcinoma were randomly selected. Two sets of body contours were established for each patient. One set of body contours did not contain the immobilization device, and the other contour set included the immobilization device...

REVIEW
Chang-Hoon Kim, Sang Chul Park
Homologous graft materials for dorsal augmentation are safe and biocompatible with a low risk of complications. Acellular dermal matrix (ADM) provides natural appearance of the nose and long-term structural integrity without extrusion, showing favorable augmentation results. Tutoplast-processed fascia lata (TPFL) is soft and easy to manipulate, providing a smooth postoperative contour of the nasal dorsum with low risk of infection or extrusion. ADM and TPFL carry low risk of major complications, such as infection, foreign body reaction, and graft extrusion...

Introduction: Uterine artery embolization (UAE) is a minimally invasive intervention that is used in the treatment of fibroids. UAE can lead to complications including postembolization syndrome, postprocedure pain, infection, endometrial atrophy leading to secondary amenorrhea, and uterine necrosis. Uterine necrosis after UAE is very rare and hence poses a clinical dilemma for any clinician in its identification and management. We document a case of uterine necrosis after UAE and conduct a literature review on its causation, clinical features, and management principles...

According to recent data, augmentation gluteoplasty continues to gain popularity in the US and globally, especially in procedures involving fat grafts. However, serious concerns about its safety have been raised over the last two years. Will this trend continue or has it already reached its peak? The answer depends on how the technique is going to be performed hereafter. In this paper, the following seven learning objectives are covered to perform gluteal augmentation safely and effectively: 1. the concept of what is a beautiful buttock and how to select the patients who will have better outcomes; 2...

Research on the optical properties of animal integuments, including fur, feather, skin and cuticle, has focussed almost exclusively on animal-visible wavelengths within the narrow range of 300-700 nm. By contrast, the near-infrared (NIR) portion of direct sunlight, spanning 700-2600 nm, has been largely ignored despite its potentially important thermal consequences. We quantified variation in visible and NIR reflectance and transmission for white body contour feathers of 50 bird species, and examined how well they are predicted by feather macro- and micro-structural morphology...

The importance of micro-electromechanical systems (MEMS) for radio-frequency (RF) applications is rapidly growing. In RF mobile-communication systems, MEMS-based circuits enable a compact implementation, low power consumption and high RF performance, e.g., bulk-acoustic wave filters with low insertion loss and low noise or fast and reliable MEMS switches. However, the cross-hierarchical modelling of micro-electronic and micro-electromechanical constituents together in one multi-physical design process is still not as established as the design of integrated micro-electronic circuits, such as operational amplifiers...

PURPOSE: To investigate the intrafractional stability of the motion relationship between the diaphragm and tumor, as well as the feasibility of using diaphragm motion to estimate lung tumor motion. METHODS: Eighty-five paired (pre and posttreatment) daily 4D-CBCT images were obtained from 20 lung cancer patients who underwent SBRT. Bony registration was performed between the pre- and post-CBCT images to exclude patient body movement. The end-exhalation phase image of the pre-CBCT image was selected as the reference image...

Clear cell papillary renal cell carcinoma (CCPRCC) is a recently recognized subtype of renal cell carcinoma entity, however, little is known about its clinical features. In the present study, 26 cases of CCPRCC were screened out from two institutions. The patient data, tissue pathology, immunohistochemical phenotype, computed tomographic images and survival analysis were studied. The mean age was 53.3 years and the average tumor size was 2.5 cm. A total of 17 patients' body mass indexes were higher than the normal level...

BACKGROUND: Anaemia and iron deficiency are common after post-bariatric abdominoplasty, which can involve removal of large areas of skin with associated blood loss. Because the oral absorbability of iron is reduced after bariatric surgery (through reduced intake, reduction of gastric acid secretion for conjugation of iron, and separation of the iron-absorptive areas of the duodenum and jejunum), it has been hypothesised that postoperative intravenous iron supplementation might be used to treat anaemia and iron deficiency in patients submitted to post-bariatric plastic surgeries...

BACKGROUND: The lumbar artery perforator flap is an alternative flap in breast reconstruction for those patients who are not eligible for a deep inferior epigastric artery perforator (DIEAP) flap. Shaping of this flap is easier compared with other flaps because of the quality of the lumbar fat and the gluteal extension. METHODS: Between October of 2010 and June of 2017, a total of 100 lumbar artery perforator free flap breast reconstructions were performed in 72 patients...

INTRODUCTION: Abdominoplasty is one of the most popular body-contouring procedures. Despite its popularity, classic abdominoplasty is still associated with a significant rate of complaints from patients such as: fullness of flanks and epigastric areas, lack of a posterior lumbar curve, hanging skin over the incision line, and visible scars over the flanks and beyond underwear or swimming suit coverage. This study reviews the authors' experience in redo abdominoplasty when the patient is not or partially satisfied with the primary procedure...
