Pulsed Radiofrequency Increases Nestin and Matrix Metalloproteinase-2 Expression in Porcine Lumbar Dorsal Root Ganglion.

Background: Pulsed radiofrequency (PRF) has been used for the treatment of chronic lumbar radicular pain and other chronic pain states. The dorsal root ganglion (DRG) consists of primary afferent somatic and visceral nerve cell bodies that transduce sensory signals from the periphery to the central part of the nervous system. It is a very important part of acute nociception, as well as the development and maintenance of chronic pain.

Detection of tick-borne pathogens in wild birds and their ticks in Western Siberia and high level of their mismatch.

The Tomsk region located in the south of Western Siberia is one of the most high-risk areas for tick-borne diseases due to elevated incidence of tick-borne encephalitis and Lyme disease in humans. Wild birds may be considered as one of the reservoirs for tick-borne pathogens and hosts for infected ticks. A high mobility of wild birds leads to unpredictable possibilities for the dissemination of tick-borne pathogens into new geographical regions.

Diagnosis and management of migraine in ten steps.

Migraine is a disabling primary headache disorder that directly affects more than one billion people worldwide. Despite its widespread prevalence, migraine remains under-diagnosed and under-treated. To support clinical decision-making, we convened a European panel of experts to develop a ten-step approach to the diagnosis and management of migraine.

Complete mitogenome of the ixodid tick (Acari: Ixodida).

Here, we present the complete mitochondrial DNA sequence of . The mitogenome is 14,806 bp and contains 13 protein-coding, 2 rRNA, and 22 tRNA genes, along with 2 control regions. mitogenome has the common mitochondrial gene order of ticks.

Development and pharmaceutical evaluation of the anticancer Anthrafuran/Cavitron complex, a prototypic parenteral drug formulation.

To improve the water solubility of the anticancer drug candidate LCTA-2034 (A1), we investigated the formation of complexes of this anthrax[2,3-b]furan congener with the solubilizing 2-hydroxypropyl derivative of β-cyclodextrin HP-βCD (Cavitron®). The interaction of A1 with HP-βCD resulted in the inclusion complex A1/HP-βCD in 1:1 stoichiometry. The A1/HP-βCD complex was used to develop a prototype of a lyophilised drug formulation with enhanced (>10-fold) aqueous solubility than A1 and a long-term stability.

Discovery of antitumor anthra[2,3-b]furan-3-carboxamides: Optimization of synthesis and evaluation of antitumor properties.

Anthraquinones and their analogues, in particular heteroarene-fused anthracendiones, are prospective scaffolds for new compounds with improved antitumor characteristics. We herein report the use of a 'scaffold hopping' approach for the replacement of the core structure in the previously discovered hit compound naphtho[2,3-f]indole-5,10-dione 2 with an alternative anthra[2,3-b]furan-5,10-dione scaffold. Among 13 newly synthesized derivatives the majority of 4,11-dihydroxy-2-methyl-5,10-dioxoanthra[2,3-b]furan-3-carboxamides demonstrated a high antiproliferative potency against a panel of wild type and drug resistant tumor cell lines, a property superior over the reference drug doxorubicin or lead naphtho[2,3-f]indole-5,10-dione 2.

Long-term monitoring and population dynamics of ixodid ticks in Tomsk city (Western Siberia).

Monitoring of two tick species (Ixodes persulcatus Schulze 1930 and Ixodes pavlovskyi Pomerantsev) was performed in four city parks of Tomsk, Russia (Camp Garden, University Park, Southern Cemetery, and Polytechnic Stadium) and in a control wild biotope in city environs (Kolarovo) in 2002-2013. Ticks were collected by flagging repeatedly after each 10 ± 1 days, starting from the disappearance of the snow cover till the end of tick activity (April-August). Gradual penetration of both tick species into city parks was demonstrated.

Synthesis and evaluation of new antitumor 3-aminomethyl-4,11-dihydroxynaphtho[2,3-f]indole-5,10-diones.

A series of new 3-aminomethyl-4,11-dihydroxynaphtho[2,3-f]indole-5,10-diones 6-13 bearing the cyclic diamine in the position 3 of the indole ring was synthesized. The majority of new compounds demonstrated a superior cytotoxicity than doxorubicin against a panel of mammalian tumor cells with determinants of altered drug response, that is, Pgp expression or p53 inactivation. For naphtho[2,3-f]indole-5,10-diones 6-9 bearing 3-aminopyrrolidine in the side chains, the ability to bind double-stranded DNA and inhibit topoisomerases 1 and 2 mediated relaxation of supercoiled DNA were demonstrated.

Complete mitogenome of the ixodid tick Ixodes pavlovskyi (Acari: Ixodida).

Here, we present complete mitochondrial DNA sequence of Ixodes pavlovskyi Pom., 1946 for the first time. The mitogenome is 14,575 bp in length and contains 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a control region.

Surveillance of tick-borne encephalitis virus in wild birds and ticks in Tomsk city and its suburbs (Western Siberia).

To study the role of wild birds in the transmission of tick borne encephalitis virus (TBEV), we investigated randomly captured wild birds bearing ixodid ticks in a very highly endemic TBE region located in Tomsk city and its suburbs in the south of Western Siberia, Russia. The 779 wild birds representing 60 species were captured carrying a total of 841 ticks, Ixodes pavlovskyi Pom., 1946 (n=531), Ixodes persulcatus P.

The tick Ixodes pavlovskyi as a host of spirochetes pathogenic for humans and its possible role in the epizootiology and epidemiology of borrelioses.

The tick Ixodes pavlovskyi is taxonomically, morphologically, and ecologically close to the taiga tick Ixodes persulcatus, a major host and vector of Borrelia spirochetes. The recent range of I. pavlovskyi is disjoined into the Western Siberian and Far Eastern parts, with this tick being almost always sympatric with I.

Variability of the tick-borne encephalitis virus genome in the 5' noncoding region derived from ticks Ixodes persulcatus and Ixodes pavlovskyi in Western Siberia.

We report the prevalence of Siberian and Far Eastern subtypes of tick-borne encephalitis virus (TBEV) in Ixodes persulcatus and Ix. pavlovskyi ticks collected in Tomsk and its suburbs during 2006-2008. The TBEV was detected in 5.
