High Temporal Variability in Late Blight Pathogen Diversity, Virulence, and Fungicide Resistance in Potato Breeding Fields: Results from a Long-Term Monitoring Study.

Long-term site-specific studies describing changes in the phenotypic variability of populations allow quantitative predictions of pathogen spread and possible outbreaks of epidemics, and provide key input for regional resistance breeding programs. Late blight samples were collected from potato () breeding fields in Estonia during a twelve-year study period between 2001 and 2014. In total, 207 isolates were assessed for mating type and 235 isolates for metalaxyl resistance and 251 isolates for virulence factors.

UVC radiation intensity dependence of pathogen decontamination rate: semiclassical theory and experiment.

A semiclassical (light classical and molecule quantum) model describing the dependence of DNA/RNA dimerization rate as function of the ultraviolet C (UVC) radiation's intensity is proposed. Particularly, a nonlinear model is developed based on the Raman-like processes in quantum optics. The main result of the theory shows that the process of dimerization in the DNA/RNA depends strongly on the UVC light's intensity, thus proving a possible quantum microscopical mechanism of the interaction of UV light with the DNA.

Expression of membrane beta-barrel protein in E. coli at low temperatures: Structure of Yersinia pseudotuberculosis OmpF porin inclusion bodies.

The recombinant OmpF porin of Yersinia pseudotuberculosis as a model of transmembrane protein of the β-barrel structural family was used to study low growth temperature effect on the structure of the produced inclusion bodies (IBs). This porin showed a very low expression level in E. coli at a growth temperature below optimal 37 °C.

The power of a control qubit in weak measurements.

In the late 80 s, a curious effect suggested by Aharanov et al. was found to lead to an anomalous amplification based on quantum measurements of weakly coupled systems. In this paper, we investigate the quantum control of the weak value amplification of a qubit system coupled to a meter.

Thermal effects on sudden changes and freezing of correlations between remote atoms in a cavity quantum electrodynamics network.

We investigate thermal effects on sudden changes and freezing of the quantum and classical correlations of remote qubits in a cavity quantum electrodynamics (CQED) network with losses. We find that the detrimental effect of thermal reservoirs on the freezing of correlations can be compensated via an efficient coupling of the fiber connecting the two cavities of the system. Furthermore, for certain initial conditions, we find a double sudden transition in the dynamics of Bures geometrical quantum discord.

[Diagnosis and treatment of acute intestinal obstruction due to gall-stone].

Results of treatment of 43 patients with acute intestinal obstruction due to gall-stones are analyzed. Forty patients were operated, 3 patients were not because of extremely severe state. Enterolythotomy was performed in 27 cases, incision of intestinal wall was carried out directly above the stones (14 cases, group 1), above or below it (13 cases, group 2).

[The association of tuberculosis with the specificities of the HLA gene DRB1 in different regions of Tuva].

The fact that genetic factors largely determine susceptibility to different diseases, including those of infectious nature is beyond question now. Tuberculosis is not an exception in this respect. HLA genes that determine different immunological phenomena make a certain contribution to tuberculosis susceptibility.

[Examining the distribution of HLA antigens in patients with tuberculosis and healthy individuals in some regions of the Republic of Tyva].

Healthy individuals and patients with pulmonary tuberculosis were typed by HLA antigens A, B, and C. They were all Tyvians and lived in different regions of the Republic of Tyva. Examination was made in 128 and 85 healthy individuals and 62 and 55 patients with pulmonary tuberculosis from the Todzhinsky and Erzinsky districts of the Republic of Tyva, respectively.

[Action of ultraviolet laser radiation on extracellular and phagocytic Mycobacteria tuberculosis in vitro].

Ultraviolet laser radiation (a wavelength of 248 nm) was examined in vitro for its bacteriostatic and bactericidal actions on M. tuberculosis H37Rv. Sterilization was achieved when a dose of 10 m/J/cm2 was applied.

[Examining the distribution of HLA antigens in patients with tuberculosis and in healthy individuals in the Erza District, Republic of Tyva].

The paper presents the results of typing by HLA classes I and II antigens in 55 patients with tuberculosis and 85 healthy Tyvians in the Erza District. Republic of Tyva. HLA I and II antigens were determined serologically and polymerase chain reaction, respectively.

[Local cerebral blood flow, cortical impedance, cerebral intravascular kinin production during forebrain ischemia and reperfusion in rats].

In the rat model of forebrain ischemia with subsequent reperfusion, an obvious formation of intravascular kinin (IVKF) occurred. The IVKF preceded and coincided in time with the maximum hyperemia and a vasogenic oedema. Local cerebral blood flow (LCBF) increased up to about 187%, at that.

[Arterial mechanoreceptor reflex as a factor for execution of hypertensive responses to disturbing effects].

It has been shown in experiments on conscious cats and rats that arterial mechanoreceptor reflex is inhibited during averse emotional influence, and the changed reflex is a cause of elevation in arterial pressure. In one's turn the hypertension contributes to entry of blood plasma norepinephrine into brain and in this way increases the arterial baroreceptor reflex after the emotional influence is stopped. The augmentation of baroreflex promotes restoration of homeostasis after cessation of the stress situation.

[Immunology of tuberculosis: current status].

The paper outlines the high-priority trends in basic and applied investigations of antituberculous immunity. It presents the results obtained from studies of the genetic mechanisms responsible for the control of susceptibility in experimental tuberculosis, from analyses of novel chemical and recombinant tuberculosis vaccines, from examinations of the role of immunological memory in the disease. While describing the results of tuberculosis immunodiagnosis, particular emphasis is laid on its major aspects: on the differential diagnosis of tuberculosis and other lung diseases and on the screening of high-risk group populations for disease progression in order to made further in-depth studies.

[Study of the central and peripheral mechanisms in enhancement of arterial baroreflex in cats during noradrenaline infusion].

An increased suppression of electrical activity of the cardiac inferior nerve by the baroreflex during norepinephrine infusion can be eliminated by a preliminary infusion of monoamine. The data obtained corroborated our previous findings that an increase in arterial pressure due to norepinephrine infusion was essential for catecholamine increasing the baroreflex inhibition of electrical activity in sympathetic nerves.

[Oxygen imbalance, blood flow and impedance of the brain in ischemia and reperfusion in rats].

In anesthetised rats, during the ischemic period a brain swelling, a decrease in oxygen tension and an increase in the blood doxygenation velocity occurred. In reperfusion, even more obvious disorders of the oxygen balance were revealed suggesting a disorder in the mitochondrial function.

[The possible mechanism of the noradrenaline enhancement of the arterial baroreceptor reflex].

In anaesthetized cats intravenous infusion of norepinephrine induced the increase in arterial pressure and suppression of renal nerve electrical activity. The latter followed the infusion was stopped and arterial pressure returned toward control. The baroreflex suppression of sympathetic activity associated with norepinephrine increased in the case of preliminary mechanical damage to blood-brain barrier.

[An experimental analysis of Mycobacterium smegmatis as a possible vector for the design of a new tuberculosis vaccine].

This study was inspired by WHO program for vaccine development. Our experimental model of lethal tuberculosis in mice was used to test whether rapidly growing avirulent M. smegmatis could be used as a live vaccination vector for screening rationalized M.

[The mechanisms regulating the value of the arterial pressure in alert rats].

N-g-nitro-L-arginine increased the mean arterial pressure in intact alert rats against the background of phenoxybenzamine and captopryl, as well as benzohexonium. The findings suggest that systems of short-term blood-pressure control are limited by the sympatho-adrenal vasopressin and renin-angiotensin systems.

[The systemic hemodynamics of waking and anesthetized male cats during noradrenaline infusion].

Dynamics of arterial pressure and its hemodynamic components were shoen to dramatically differ in corscious and anesthetised animals. The data obtained suggest that corscious male cats, along with a baroreflex mechanism of resistance against involvement of the heart into the pressor response, have another mechanism acting in deficiency of baroreflex effects.
