Physical-mechanical properties of composite light-cured materials

Composite stomatological light-cured materials with a polymer matrix, bonding layer and inorganic filling (glass) are examined. The requirements imposed on these materials by modern therapeutical stomatology are indicated. The composition and some technological aspects of the production of the new material are presented. An investigation of the physical-mechanical properties of the new composite material (strength, water absorption, polymerization depth) showed that these indices are on par with the best foreign analog

Observation of time quasicrystal and its transition to superfluid time crystal

We report experimental realization of a quantum time quasicrystal, and its transformation to a quantum time crystal. We study Bose-Einstein condensation of magnons, associated with coherent spin precession, created in a flexible trap in superfluid $^3$He-B. Under a periodic drive with an oscillating magnetic field, the coherent spin precession is stabilized at a frequency smaller than that of the drive, demonstrating spontaneous breaking of discrete time translation symmetry. The induced precession frequency is incommensurate with the drive, and hence the obtained state is a time quasicrystal. When the drive is turned off, the self-sustained coherent precession lives a macroscopically-long time, now representing a time crystal with broken symmetry with respect to continuous time translations. Additionally, the magnon condensate manifests spin superfluidity, justifying calling the obtained state a time supersolid or a time super-crystal

Magnetic Phase Separation and Magnetic Moment Alignment in Ordered Alloys FE 65

The structure and the magnetic state of ordered Fe65Al35-xMx (Mx = Ga, B; x = 0; 5 at.%) alloys are investigated using X-ray diffraction, Mössbauer spectroscopy, and magnetic measurements. The behavior of the magnetic characteristics and Mössbauer spectra of the binary alloy Fe65Al35 and the ternary alloy with gallium addition Fe65Al30Ga5 is explained in terms of the phase separation into two magnetic phases: a ferromagnetic one and a spin density wave. It is shown that the addition of boron to the initial binary alloy Fe65Al35 results in the ferromagnetic behavior of the ternary alloy

COGNITIVE IMPAIRMENTS AFTER STROKE

Thirty-two patients (mean age 53.912.4 years) with prior stroke were examined to clarify the pattern and degree of cognitive impairments depending on the site of a lesion. A control group comprised 32 subjects (mean age 52.112.9 years) without nervous system pathology. The authors made a complete clinical study to evaluate the neurological and mental status, a standardized interview, and A.R. Luria's neuropsychological tests. The patients with prior stroke were found to have lower values of auditory-verbal short-term and long-term memory, impaired concentration and voluntary attention scope. Mild cognitive disorders were established in middle-aged patients and moderate cognitive disorders of amnestic multifunctional type were in elderly patients. Auditory-verbal memory, visual gnosis, and some speech-related thought functions were impaired when in the involvement of the temporal and posterior frontal lobes in patients with prior stroke in the middle cerebral artery bed. Impaired visual image recognition and lower visual voluntary attention were detected in patients with prior stroke in the anterior and posterior cerebral arteries

Diagnostics program of endometrai receivabiiity disorders in patients with reproductive failures

In order to optimize the algorithm for the diagnosis of endometrial receptivity disorders, a prospective, comparative, controlled study was conducted, involving 210 patients, including 182 patients with endometrial hypoplasia, clinically manifested as infertility, miscarriage, unsuccessful attempts at ART, and 28 fertile, conditionally healthy patients with a history term delivery, which resulted in the birth of healthy children. A comparative analysis of the anamnesis data, pelvic ultrasound of the pelvic organs, morphological and immunohistochemical analysis of endometrial specimens taken on the day of the supposed 'implantation window' on day 7 after ovulation, determined by urinary test data, office hysteroscopy. A system of diagnostic measures has been developed that provides an assessment of informative ultrasound, morphofunctional characteristics and state of endometrial microbiota, diagnostic hysteroscopy and determination of endometrial receptivity according to the developed prognosis model, which allows to diagnose, with 92.5% accuracy, infringements of endometrial receptivity and to detail their cause.С целью оптимизации программы диагностики нарушений рецептивности эндометрия проведено проспективное сравнительное контролируемое исследование, включающее 210 пациенток, в том числе 182 пациентки с гипоплазией эндометрия, клинически проявляющейся в виде бесплодия, невынашивания беременности, неудачными попытками ВРТ, и 28 фертильных условно здоровых пациенток, имеющих в анамнезе срочные роды, закончившиеся рождением здоровых детей. Проведен сравнительный анализ данных анамнеза, ультразвукового исследования органов малого таза, данных морфологического и иммуногистохимического анализа образцов эндометрия, взятых в день предполагаемого «окна имплантации» на 7 день после овуляции, определяемой по данным мочевого теста, офисная гистероскопия. Разработана система диагностических мероприятий, предусматривающая оценку информативных ультразвуковых, морфофункциональных характеристик и состояния микробиоты эндометрия, диагностическую гистероскопию и определение рецептивности эндометрия по разработанной модели прогноза, что позволяет с точностью 92,5% диагностировать нарушения рецептивности эндометрия и детализировать их причину

Study of vaginal microbiota in postmenopausal women with surgical correction of genital prolapse

The study of the vaginal microflora of women with genital prolapse (GP), who are ref erred to surgical treatment, is of particular importance. Infectious and inflammatory complications after the surgical correction of GP significantly increase the recovery time, the length of the patient’s hospital stay and the cost of treatment. It is important to be able to change the qualitative composition of microflora, thereby exerting a beneficial effect on the course of the postoperative period, affecting the outcome of surgical treatment. Evaluation of the vaginal microbiota by real-time polymerase chain reaction in postmenopausal women with surgical correction of genital prolapse against the background of using low-dose local therapy regimens with a drug containing estriol, progesterone and Lactobacillus culture

Child injuries in a modern city

In a large industrial city, an analysis of children’s injuries was carried out from 2010 to 2016. The negative dynamics of the increase in the number of injuries has been established, with an annual growth rate of 3.5%. In the structure, the largest share was domestic and street injuries, respectively 43.4 and 39.0%. The most severe traumatic injuries took place in the victims of the accident, a third of which (30%) needed to be hospitalized. For a more complete account of injuries and investigation of circumstances, their official registration in the “Center of Hygiene and Epidemiology” is necessary. Another direction is the adjustment of educational programs.В крупном промышленном городе проведен анализ детского травматизма с 2010-го по 2016 год. Установлена негативная динамика увеличения количества травм, с ежегодным темпом прироста в 3,5%. В структуре наибольшую долю составляли бытовая и уличная травмы, соответственно 43,4 и 39,0%. Наиболее тяжелые травматические повреждения имели место у пострадавших в ДТП, треть из них (30%) нуждались в госпитализации и лечении в стационаре. Для более полного учета травм и расследования обстоятельств необходима их официальная регистрация в «ЦГиЭ». Другое направление профилактики — корректировка образовательных программ по БЖД
