Thoracic metastasis in advanced ovarian cancer: comparison between computed tomography and video-assisted thoracic surgery.
OBJECTIVE: To determine which computed tomography (CT) imaging features predict pleural malignancy in patients with advanced epithelial ovarian carcinoma (EOC) using video-assisted thoracic surgery (VATS), pathology, and cytology findings as the reference standard. METHODS: This retrospective study included 44 patients with International Federation of Obstetrics and Gynecology (FIGO) stage III or IV primary or recurrent EOC who had chest CT ≤30 days before VATS. Two radiologists independently reviewed the CT studies and recorded the presence and size of pleural effusions and of ascites; pleural nodules, thickening, enhancement, subdiaphragmatic tumour deposits and supradiaphragmatic, mediastinal, hilar, and retroperitoneal adenopathy; and peritoneal seeding. VATS, pathology, and cytology findings constituted the reference standard. RESULTS: In 26/44 (59%) patients, pleural biopsies were malignant. Only the size of left-sided pleural effusion (reader 1: rho=-0.39, p=0.01; reader 2: rho=-0.37, p=0.01) and presence of ascites (reader 1: rho=-0.33, p=0.03; reader 2: rho=-0.35, p=0.03) were significantly associated with solid pleural metastasis. Pleural fluid cytology was malignant in 26/35 (74%) patients. Only the presence (p=0.03 for both readers) and size (reader 1: rho=0.34, p=0.04; reader 2: rho=0.33, p=0.06) of right-sided pleural effusion were associated with malignant pleural effusion. Interobserver agreement was substantial (kappa=0.78) for effusion size and moderate (kappa=0.46) for presence of solid pleural disease. No other CT features were associated with malignancy at biopsy or cytology. CONCLUSION: In patients with advanced EOC, ascites and left-sided pleural effusion size were associated with solid pleural metastasis, while the presence and size of right-sided effusion were associated with malignant pleural effusion. No other CT features evaluated were associated with pleural malignancy
INTERPERSONAL SPACE OF VITAL FUNCTIONS AS THE SYSTEM OF MINDFULNESS DEVELOPMENT
Исследование, представленное в статье, призвано внести вклад в решение важной проблемы социальной адаптации личности на этапах профессионального становления, развития и совершенствования. В связи с этим, перед современной системой профессионального образования возникает ряд вопросов, связанных, в первую очередь, с эффективностью работы в области взаимодействия всех субъектов профессионального образования. Развитие личностной осознанности – важная задача личностного совершенствования. Проблема развития осознанности – ключевой аспект развития Личности. Понятие «Осознание» как совокупность процесса и результата («осознанность») интеграции информационного потенциала, проявленное как целостная структура отдельных интеграционных потенциалов в индивидуальном свободном сознании.Цель работы заключается в разработке и апробации метода IAI (интроспективный анализ интерперсоны) жизнедеятельности человека, который является инновационным инструментом мониторинговых исследований профессионально-педагогических проблем и задач, а также отправной точкой для создания унифицированной системы развития осознанности с целью профилактики внутриличностных и межличностных конфликтов.Результаты исследования показали, что в процессе применения метода IAI (интроспективный анализ интерперсоны) повысился уровень понимания к педагогическим требованиям, проявились явные формы осознанного поведения. Взаимоотношения людей в процессе эксперимента строятся на основе осознанного восприятия личности партнера, с четким осознанием именно коммуникативной цели, полноценной ответственностью за коммуникативный процесс и твердым намерением решить поставленную коммуникативную задачу.The study presented in the article is intended to contribute to the solution of the important problem of social adaptation of a person at the stages of professional development and improvement. In this regard, a number of questions arise in front of the modern system of vocational education related to the effectiveness of work in the field of interaction of all subjects of vocational education. Development of personal mindfulness is an important task of personal development. The problem of development of mindfulness is a key aspect of personal development. The concept of “Mindfulness” as a set of process and result (“mindfulness”) of the integration of information potential, manifested as an integral structure of individual integration potentials in the individual free consciousness.The aim of the work is to develop and test the IAI method (introspective analysis of interpersons) of human life, which is an innovative tool for monitoring research of professional and pedagogical problems and tasks, as well as a starting point for creating a unified system for developing awareness to prevent intrapersonal and interpersonal conflicts.The results of the study showed that in the process of applying the method of IAI (introspective analysis of interpersonal) the level of understanding of pedagogical requirements increased, manifested clear forms of conscious behavior. Relationships between people in the experiment are based on a conscious perception of the partner’s personality, with a clear understanding of the communicative purpose, full responsibility for the communicative process and a firm intention to solve the communicative tasks

Water-soluble hybrid materials based on {Mo₆X₈}⁴⁺ (X = Cl, Br, I) cluster complexes and sodium polystyrene sulfonate
Development of water-soluble forms of octahedral molybdenum clusters {Mo₆X₈}⁴⁺ (X = Cl, Br, I) is strongly motivated by the tremendous potential that these complexes have for biological applications, namely as agents for bioimaging and photodynamic therapy. In these work we report the first water-soluble hybrid materials, which represent sodium polystyrene sulfonate doped by molybdenum clusters, and evaluation of their photophysical and biological properties (dark and photoinduced cytotoxicity and cellular uptake) with the use of cervical cancer (HeLa) and human epidermoid larynx carcinoma (Hep-2) cell-lines as models
Bacterial Nitric Oxide Extends the Lifespan of C. elegans
SummaryNitric oxide (NO) is an important signaling molecule in multicellular organisms. Most animals produce NO from L-arginine via a family of dedicated enzymes known as NO synthases (NOSes). A rare exception is the roundworm Caenorhabditis elegans, which lacks its own NOS. However, in its natural environment, C. elegans feeds on Bacilli that possess functional NOS. Here, we demonstrate that bacterially derived NO enhances C. elegans longevity and stress resistance via a defined group of genes that function under the dual control of HSF-1 and DAF-16 transcription factors. Our work provides an example of interspecies signaling by a small molecule and illustrates the lifelong value of commensal bacteria to their host

DESCRIPTION OF ATTENTION FUNCTION FEATURES IN ARCTIC POPULATION
Abstract. The states of the Cold area similarly unfavorably influence the condition of higher types of willfulconsideration among all inhabitants, leveling the factor of individual contrasts. An individual's stay in the Ice locale is joined by change of the utilitarian asymmetry of the cerebrum and a lessening in the ordinary capacity of the overwhelming side of the equator. The got discoveries recommend a particular right asymmetry of consideration among agents of indigenous populace of the Cold district. The agents of the non-indigenous populace with age and an expansion in the term of their stay in the Ice locale altogether increment the extent of individuals with a fractional kind of consideration asymmetry, which additionally mirrors the difference in hemispheric collaboration, because of the expanded impact of the correct half of the globe. The got information are reliable with the suppositions about the insecurity of practical asymmetry and the likelihood of its change affected by distressing occasions, which incorporatethe general population's stay in the Ice locale.Keywords: attention function, the Arctic Region, encephalic asymmetry, aborigines of the North
Synthesis of Molecular Dodecanuclear Carbon-centered Rhenium Cluster Re12CS17 and its Conducting Properties
The unique dodecanuclear cluster compound Re12CS17 was prepared and studied by X-ray, complex impedance method and density functional theory (DFT). The compound is amorphous, possesses semiconducting properties. Computer simulations showed that the Re and S atoms at the external borders of the neighboring molecules Re12CS17 can form sufficiently strong Re•••S intermolecular bonds, similar to the Mo•••S intermolecular bonds of cuboctahedron Mo6S8 molecules in the Chevrel phases.
