Features of the immunological profile of blood and urine in patients with post-infectious glomerulonephritis.

The timely diagnosis and treatment of post-infectious glomerulonephritis (PIGN) is currently limited by the erased and low-symptom nature of the disease, which leads to the search for informative biological markers of the disease, which can be used as immunological indicators of blood and urine. The study was carried out in order to establish the characteristic changes in the immunological parameters of blood and urine in patients with PIGN. The study included 60 patients with PIGN from among the patients, hospitalized in the nephrology department of the Republican Clinical Hospital of Health Care Ministry of the Chuvash Republic in 2015-2018.

Conversion from electrocardiosignals to equivalent electrical sources on heart surface.

Background: The actual task of electrocardiographic examinations is to increase the reliability of diagnosing the condition of the heart. Within the framework of this task, an important direction is the solution of the inverse problem of electrocardiography, based on the processing of electrocardiographic signals of multichannel cardio leads at known electrode coordinates in these leads (Titomir et al. Noninvasiv electrocardiotopography, 2003), (Macfarlane et al.

[Osteoarthrosis in patients with type 2 diabetes mellitus].

Aim: To estimate the frequency of a comorbidity of type 2 diabetes mellitus (DM) and osteoarthrosis (OA) in relation to patient age and to identify risk factors for degenerative and dystrophic changes in the joints.

Subjects And Methods: 160 patients with type 2 diabetes (23 men and 137 women at the age of 44 to 82 years; body mass index 33 +/- 5 kg/m2 were examined. A control group consisted of 112 age- and gender-matched subjects without type 2 DM.

Oligomeric adiponectin forms and their complexes in the blood of healthy donors and patients with type 2 diabetes mellitus.

Adiponectin (Adn) is a protein that circulates in the blood in several oligomeric forms, namely low-, medium-, and high-molecular-weight forms. Adn may serve as a risk factor for type 2 diabetes mellitus (T2DM). The aims of this work were (1) to produce monoclonal antibodies (MAbs) specific to different Adn oligomeric forms, (2) to design immunoassays suitable for measuring the Adn forms present in human blood, and (3) to investigate the changes in Adn forms that occur in patients with T2DM.

Role of KCNQ channels in skeletal muscle arteries and periadventitial vascular dysfunction.

KCNQ channels have been identified in arterial smooth muscle. However, their role in vasoregulation and chronic vascular diseases remains elusive. We tested the hypothesis that KCNQ channels contribute to periadventitial vasoregulation in peripheral skeletal muscle arteries by perivascular adipose tissue and that they represent novel targets to rescue periadventitial vascular dysfunction.

Embryonic development in ballan wrasse Labrus bergylta.

Eight primary embryonic developmental stages were assigned to eggs of ballan wrasse Labrus bergylta using key morphological features following standardized nomenclature: Ia, Ib, II, III, IV, V, VI and VI+, reared from single family clutches under comparable environmental conditions in Ireland and Norway. Development in L. bergylta is typical of demersal marine finfish species with a short egg stage.

[Cell as an integral water-dependent system in onthogenesis].

The study proposes a model of plant cell as an integral physical and physical-chemical water-dependent system of maximum structural complexity and complete combination of functions. The framework of this model allows analyzing any cell of simpler organization in any degree of reduction, animal cell included. The model justifies priority in the establishment of internal and functional (turgor) cell pressure of its cytoplasmatic solution high-molecular component along the chain: genome-->protein (quality and quantity)-->functional(turgor) pressure-->cell internal pressure-->water content in cell, gradual decrease of which results in cell death.

Immunological mechanisms of recovery from an acute stage in patients with atopic bronchial asthma.

We have conducted a comparative study of the lymphocyte surface antigens in patients with atopic bronchial asthma (ABA) in an acute stage and during clinical remission of the disease using a wide variety of monoclonal antibodies. In patients with ABA, independently of the stage of the disease, we have observed a decline in the total number of T lymphocytes due to cell reduction in both sub-populations--T helpers and cytotoxic T cells. During the acute phase of the disease a significant increase in the number of B lymphocytes at all stages of differentiation was observed.

[In vitro maturation of cattle oocytes taken from ovaries with different morphofunctional states].

We studied the capacity of cattle oocytes taken from ovaries with different morphofunctional state for development to metaphase 2 in vitro. A classification of ovaries has been proposed according to their morphofunctional state: (1) ovaries with a yellow body from the last cycle, without dominating follicle, with many follicles of varying diameter; (2) ovaries with a yellow body from the last cycle, with dominating follicle (from 10 mm in diameter); (3) ovaries with a large functioning yellow body and follicles of varying diameter; (4) ovaries with a follicular cystoid formation (more than 25 mm in diameter); (5) ovaries with a yellow body from past cycles and small (1-2 mm) follicles, supposedly with a weakened hormonal function. It was shown that the morphofunctional state of ovaries determined the total number of oocytes isolated from an ovary and number of morphologically normal oocytes feasible for cultivation.
