Одна группа принимала перед началом лечения две таблетки валерианы, а затем, сравнивали показатели

Telemedicine and international disaster response: Medical consultation to Armenia and Russia via a telemedicine spacebridge

The Telemedicine Spacebridge, a satellite mediated audio-video-fax link between four U.S. and two Armenian and Russian medical centers, permitted remote American consultants to assist Armenian and Russian physicians in the management of medical problems following the December 1988 earthquake in Armenia and the June 1989 gas explosion near Ufa. During 12 weeks of operations, 247 Armenian and Russian and 175 American medical professionals participated in 34 half-day clinical conferences. 209 patients were discussed, requiring expertise in 20 specialty areas. Telemedicine consultations resulted in altered diagnoses for 54, new diagnostic studies for 70, altered diagnostic processes for 47, and modified treatment plans for 47 of 185 Armenian patients presented. Simultaneous participation of several U.S. medical centers was judged beneficial; quality of data transmission was judged excellent. These results suggest that interactive consultation by remote specialists can provide valuable assistance to onsite physicians and favorably influence clinical decisions in the aftermath of major disasters

A method for producing a model of chronic periodontitis in rats

This article describes the creation of a model of chronic periodontitis in animals (rats) to determine the optimal timing of the treatment of this pathology. Investigations were carried out on five Wistar rats, which all-metal needle was inserted 12 mm long in the gingival margin to the vestibular surface of the right lower incisor to close along the medial edge of the tooth with a little effort to break the tissues. Then conducted visual surveillance of the external signs of inflammation: evaluation of color gums alveolar bone of the lower jaw. measuring the size of edema, consistency, instrumentally, using dental probe measured the depth of the gingival pocket and the presence of bleeding, defined mobility. Microscopically evaluated quantitatively the presence of plasma cells in the fields of view, which corresponds to a phase prevalence of chronic inflammation. The created model provides a great opportunity to explore existing pharmacological agents, as well as search or the creation of new dosage forms in the study on the chronic stage of the process, as well as a significant validation of the selected medicament for the treatment of this pathology.В статье приводится описание создания модели хронического пародонтита на животных (крысах) для определения оптимальных сроков начала лечения данной патологии. Исследования проведены на пяти крысах линии Вистар, которым вводилась игла цельнометаллическая длинной 12 мм в десневой край с вестибулярной поверхности правого нижнего резца с медиального края вплотную вдоль зуба с небольшим усилием для разрыва тканей. Затем проводилось визуальное наблюдение за внешними признаками воспаления: оценка цвета десны альвеолярного отростка нижней челюсти, измерение размера отека, консистенции, инструментально, с помощью стоматологического зонда проведены измерения глубины десневого кармана и наличие кровоточивости, определена подвижность. Микроскопически оценивалось количественное наличие плазматических клеток в полях зрения, преобладание которых соответствует фазе хронизации воспалительного процесса. Созданная модель предоставляет обширные возможности для исследования уже имеющихся фармакологических препаратов, а так же поиск или создание новых лекарственных форм при исследовании на стадии хронического процесса, а также достоверное подтверждение правильности выбранного лекарственного средства для лечения данной патологии

Negative perceptions of aging and decline in walking speed: A self-fulfilling prophecy

Introduction Walking speed is a meaningful marker of physical function in the aging population. While it is a primarily physical measure, experimental studies have shown that merely priming older adults with negative stereotypes about aging results in immediate declines in objective walking speed. What is not clear is whether this is a temporary experimental effect or whether negative aging stereotypes have detrimental effects on long term objective health. We sought to explore the association between baseline negative perceptions of aging in the general population and objective walking speed 2 years later. Method 4,803 participations were assessed over 2 waves of The Irish Longitudinal Study on Ageing (TILDA), a prospective, population representative study of adults aged 50+ in the Republic of Ireland. Wave 1 measures – which included the Aging Perceptions Questionnaire, walking speed and all covariates - were taken between 2009 and 2011. Wave 2 measures – which included a second measurement of walking speed and covariates - were collected 2 years later between March and December 2012. Walking speed was measured as the number of seconds to complete the Timed Up-And-Go (TUG) task. Participations with a history of stroke, Parkinson’s disease or an MMSE < 18 were excluded. Results After full adjustment for all covariates (age, gender, level of education, disability, chronic conditions, medications, global cognition and baseline TUG) negative perceptions of aging at baseline were associated with slower TUG speed 2 years later (B=.03, 95% CI = .01 to 05, p< .01). Conclusions Walking speed has previously been considered to be a consequence of physical decline but these results highlight the direct role of psychological state in predicting an objective aging outcome. Negative perceptions about aging are a potentially modifiable risk factor of some elements of physical decline in aging

Search for Higgs Bosons in e+e- Collisions at 183 GeV

The data collected by the OPAL experiment at sqrts=183 GeV were used to search for Higgs bosons which are predicted by the Standard Model and various extensions, such as general models with two Higgs field doublets and the Minimal Supersymmetric Standard Model (MSSM). The data correspond to an integrated luminosity of approximately 54pb-1. None of the searches for neutral and charged Higgs bosons have revealed an excess of events beyond the expected background. This negative outcome, in combination with similar results from searches at lower energies, leads to new limits for the Higgs boson masses and other model parameters. In particular, the 95% confidence level lower limit for the mass of the Standard Model Higgs boson is 88.3 GeV. Charged Higgs bosons can be excluded for masses up to 59.5 GeV. In the MSSM, mh > 70.5 GeV and mA > 72.0 GeV are obtained for tan{beta}>1, no and maximal scalar top mixing and soft SUSY-breaking masses of 1 TeV. The range 0.8 < tanb < 1.9 is excluded for minimal scalar top mixing and m{top} < 175 GeV. More general scans of the MSSM parameter space are also considered.Comment: 49 pages.

A Measurement of the Product Branching Ratio f(b->Lambda_b).BR(Lambda_b->Lambda X) in Z0 Decays

The product branching ratio, f(b->Lambda_b).BR(Lambda_b->Lambda X), where Lambda_b denotes any weakly-decaying b-baryon, has been measured using the OPAL detector at LEP. Lambda_b are selected by the presence of energetic Lambda particles in bottom events tagged by the presence of displaced secondary vertices. A fit to the momenta of the Lambda particles separates signal from B meson and fragmentation backgrounds. The measured product branching ratio is f(b->Lambda_b).BR(Lambda_b->Lambda X) = (2.67+-0.38(stat)+0.67-0.60(sys))% Combined with a previous OPAL measurement, one obtains f(b->Lambda_b).BR(Lambda_b->Lambda X) = (3.50+-0.32(stat)+-0.35(sys))%.Comment: 16 pages, LaTeX, 3 eps figs included, submitted to the European Physical Journal

Measurement of the Michel Parameters in Leptonic Tau Decays

The Michel parameters of the leptonic tau decays are measured using the OPAL detector at LEP. The Michel parameters are extracted from the energy spectra of the charged decay leptons and from their energy-energy correlations. A new method involving a global likelihood fit of Monte Carlo generated events with complete detector simulation and background treatment has been applied to the data recorded at center-of-mass energies close to sqrt(s) = M(Z) corresponding to an integrated luminosity of 155 pb-1 during the years 1990 to 1995. If e-mu universality is assumed and inferring the tau polarization from neutral current data, the measured Michel parameters are extracted. Limits on non-standard coupling constants and on the masses of new gauge bosons are obtained. The results are in agreement with the V-A prediction of the Standard Model.Comment: 32 pages, LaTeX, 9 eps figures included, submitted to the European Physical Journal
