Hydrogen Inhalation Reduces Lung Inflammation and Blood Pressure in the Experimental Model of Pulmonary Hypertension in Rats.

Hydrogen has been shown to exhibit selective antioxidant properties against hydroxyl radicals, and exerts antioxidant and anti-inflammatory effects. The monocrotaline-induced model of pulmonary hypertension is suitable for studying substances with antioxidant activity because oxidative stress is induced by monocrotaline. On day 1, male Wistar rats were subcutaneously injected with a water-alcohol solution of monocrotaline or a control with an only water-alcohol solution.

The article is dedicated to the 100th anniversary of the birth of a prominent Soviet and Russian neurologist, professor, doctor of medical sciences Yuri Stepanovich Martynov. The article reflects the life of Yu.S.

[Medical solution to needle breakage during local anesthesia].

Needle breakage may be a damaging experience for both medical practitioners and patients. Medical literature provides numerous cases of dental practitioners being confronted with this problem. We have studied the clinical case of the patient L.

[The ethnic factor in dentistry as a component of personalized medicine].

Personalized medicine is the choice of treatment based on the individual characteristics of the patient due to genetic and environmental factors. The latter are to a certain degree determined by an ethnic group. This article discusses ethnic aspects in the structure of the maxillofacial area, the prevalence, development, treatment and prevention of dental diseases.

Sex Accent and Biphonation in the Sound Signal of Ground Squirrels (Mammalia, Rodentia).

The alarm call of the little ground squirrel (Spermophilus pygmaeus), like those of six other Eurasian ground squirrels, contains a high-frequency component. In males, the peak and maximum frequencies of the high-frequency component are higher than in females. Biphonation of the alarm calls of Sp.

[Change of phenotypic properties of escape mutants and readaptants of influenza virus A (H1N1)pdm09 under the influence of selected mutations in the molecule of hemagglutinin.].

Introduction: After the emergence and spread of pandemic H1N1 viruses in 2009, antigenic epitopes recognized by neutralizing antibodies against the hemagglutinin of influenza A/Moscow/01/09(H1N1)pdm09 viruses were studied.

Purpose: The purpose of the study was to obtain readapted variants of the virus from a low-virulent escapemutant that has an increased affinity of the avian and the human types cellular receptors compared to the wild type and the comparative study of their antigenic and receptor specificity.

Material And Methods: Viruses were accumulated in 10-day-old chicken embryos.

[Evolution of pandemic influenza virus A(H1N1)pdm09 in 2009-2016: dynamics of receptor specificity of the first hemagglutinin subunit (HA1).].

Introduction: The new reassortant of the swine flu virus A(H1N1)pdm09, which emerged in 2009, overcame the species barrier and caused the 2009-2010 pandemic. One of the key points required for the influenza virus to overcome the species barrier and adapt it to humans is its specific binding to the receptors on the epithelium of the human respiratory tract.

Purpose: Studying the dynamics of changes in receptor specificity (RS) of the HA1 subunit of the hemagglutinin of the influenza A(H1N1)pdm09 virus strains isolated during the period 2009-2016 on the territory of the Russian Federation, and an analysis of the possible impact of these changes on the incidence rates of the population of the Russian Federation of pandemic influenza in certain epidemic seasons.

[Evaluation of the molecularbiological properties of human rotavirus A strain WA.].

Background: Rоtaviruses are amоng the leading causes of severe diarrhea in children all over the Wоrld. Vaccination is considered to be the mоst effective way to cоntrоl the disease. Currently available vaccines for prevention of rоtavirus infection are based on live attenuated rotavirus strains human оr animal origin.

[Assessment of immunogenic activity of the cloned human rotavirus A WA strain.].

Introduction: Rotovirus infection (RVI) caused by the dsRNA-containing virus from genus Rotavirus, Reoviridae family, belonging to group A (RVA), is the cause of severe diarrhea in human and other mammalian species. Vaccination is the most effective way to reduce the incidence of RVI. At present, the effectiveness of using gnotobiotic piglets as a universal model for reproducing human rotavirus infection and assessing the quality of RVI vaccine preparations has been experimentally proven.

[Neurophysiological assessment of persistent idiopathic facial pain].

Aim: To study neurophysiological characteristics of persistent idiopathic facial pain (PIFP) in comparison to trigeminal neuralgia.

Material And Methods: Forty-five patients with PIFP at the age from 25 to 74 years (42 women and 3 men), 25 patients with trigeminal neuralgia at the age from 25 to 84 (15 women and 10 men) and 20 healthy volunteers were examined. Multimodal evoked potentials (EP): brainstem auditory (BAEPs), trigeminal (TEPs) and sympathetic skin responses (SSRs) evoked potentials were recorded.
