Polynucleotide-based treatments for various facial scars including combat injuries.

Introduction: This study examines the therapeutic efficacy of polynucleotide-based therapies, specifically REJURAN, for managing scars and burns. Scars and burns present significant challenges in dermatology, often affecting patients' quality of life. Traditional treatments can be limited in effectiveness, prompting the exploration of innovative approaches like polynucleotide therapy, which utilizes salmon DNA to stimulate tissue repair, modulate inflammation, and enhance collagen production.

The Role of TRP Channels in Sepsis and Colitis.

To date, several members of the transient receptor potential (TRP) channels which provide a wide array of roles have been found in the gastrointestinal tract (GI). The goal of earlier research was to comprehend the intricate signaling cascades that contribute to TRP channel activation as well as how these receptors' activity affects other systems. Moreover, there is a large volume of published studies describing the role of TRP channels in a number of pathological disorders, including inflammatory bowel disease (IBD) and sepsis.

Embodied Processing at Six Linguistic Granularity Levels: A Consensus Paper.

Language processing is influenced by sensorimotor experiences. Here, we review behavioral evidence for embodied and grounded influences in language processing across six linguistic levels of granularity. We examine (a) sub-word features, discussing grounded influences on iconicity (systematic associations between word form and meaning); (b) words, discussing boundary conditions and generalizations for the simulation of color, sensory modality, and spatial position; (c) sentences, discussing boundary conditions and applications of action direction simulation; (d) texts, discussing how the teaching of simulation can improve comprehension in beginning readers; (e) conversations, discussing how multi-modal cues improve turn taking and alignment; and (f) text corpora, discussing how distributional semantic models can reveal how grounded and embodied knowledge is encoded in texts.

Inflammatory Bowel Disease: Crosstalk between Histamine, Immunity, and Disease.

Inflammatory bowel disease (IBD) is increasingly recognized as a serious, worldwide public health concern. It is generally acknowledged that a variety of factors play a role in the pathogenesis of this group of chronic inflammatory diseases. The diversity of molecular actors involved in IBD does not allow us to fully assess the causal relationships existing in such interactions.

Hypoxia and Intestinal Inflammation: Common Molecular Mechanisms and Signaling Pathways.

The gastrointestinal tract (GI) has a unique oxygenation profile. It should be noted that the state of hypoxia can be characteristic of both normal and pathological conditions. Hypoxia-inducible factors (HIF) play a key role in mediating the response to hypoxia, and they are tightly regulated by a group of enzymes called HIF prolyl hydroxylases (PHD).

Polymorphism of toll-like receptor genes and autoimmune endocrine diseases.

In recent years, there has been a significant amount of interest and vigorous studies on mutations related to innate immunity receptor genes such as Toll-like receptors (TLR), which is driven by the identification of many associations between these mutations and development of various disorders leading, in particular, to autoimmune diseases. It has been proven that the occurrence of single nucleotide polymorphisms in DNA sequences encoding TLRs causes malfunction of some key signaling pathways, and, as a result, increases the risk of autoimmune diseases. The identification of these polymorphisms can lead to the understanding of the pathogenesis of autoimmune diseases, which subsequently will create effective methods for the prevention and treatment thereof.

Cloning, purification and structure determination of the HIV integrase-binding domain of lens epithelium-derived growth factor.

Lens epithelium-derived growth factor (LEDGF)/p75 is the dominant binding partner of HIV-1 integrase in human cells. The crystal structure of the HIV integrase-binding domain (IBD) of LEDGF has been determined in the absence of ligand. IBD was overexpressed in Escherichia coli, purified and crystallized by sitting-drop vapour diffusion.

[Relapsing (recurrent) disease caused by Borrelia miyamotoi].

Aim: To clarify the clinical, laboratory, and epidemiological characteristics of relapsing Ixodes tick-borne borreliosis (ITB) caused by Borrelia miyamotoi.

Subjects And Methods: Retrospective clinical observation was made in 79 inpatients of the Republican Infectious Diseases Hospital (Udmurt Republic), who had been diagnosed with B. miyamotoi-caused disease verified by real-time polymerase chain reaction.

Expression of Pattern Recognition Receptors by Nociceptive Metasympathetic Neurons.

Immunohistochemical assay with double label and confocal laser scanning microscopy showed that innate immunity receptor TLR4 is expressed predominantly in neurons of the intestinal Auerbach (myenteric) plexus, while vanilloid nociceptive receptor TRPV1 is expressed by neurons of Meissner (submucous) plexus. Immunohistochemical analysis with triple labeling revealed coexpression of TLR4 and TRPV1 in enteric neurons of rat colon. The results attest to a possibility of functional interaction between Toll-like and vanilloid receptors in the neuron level.

The incidence of West Nile disease in Russia in relation to climatic and environmental factors.

Since 1999, human cases of West Nile fever/neuroinvasive disease (WND) have been reported annually in Russia. The highest incidence has been recorded in three provinces of southern European Russia (Volgograd, Astrakhan and Rostov Provinces), yet in 2010-2012 the distribution of human cases expanded northwards considerably. From year to year, the number of WND cases varied widely, with major WND outbreaks in 1999, 2007, 2010, and 2012.

Structural basis for LMO2-driven recruitment of the SCL:E47bHLH heterodimer to hematopoietic-specific transcriptional targets.

Cell fate is governed by combinatorial actions of transcriptional regulators assembling into multiprotein complexes. However, the molecular details of how these complexes form are poorly understood. One such complex, which contains the basic-helix-loop-helix heterodimer SCL:E47 and bridging proteins LMO2:LDB1, critically regulates hematopoiesis and induces T cell leukemia.

[Non-invasive techniques in diagnosis of steatosis and fibrosis in nonalcoholic fatty liver disease].

Unlabelled: Diagnosis and treatment of nonalcoholic fatty liver disease (NAFLD) is one of the most actual problems of modern hepatology. Ultrasound elastometry is alternative method to determine the density of the liver tissue. The efficiency of the method was confirmed by a large amount of data in patients with viral hepatitis.

Crystal structure and function of human nucleoplasmin (npm2): a histone chaperone in oocytes and embryos.

Human Npm2 is an ortholog of Xenopus nucleoplasmin (Np), a chaperone that binds histones. We have determined the crystal structure of a truncated Npm2-core at 1.9 Å resolution and show that the N-terminal domains of Npm2 and Np form similar pentamers.

Development of aptamer therapeutics.

The field of aptamer research is growing rapidly, with ∼230 papers using the word 'aptamer' published from January to June 2010. These reports cover many different applications ranging from tools to study protein function to potential diagnostic and therapeutic agents. In this review we will focus on the processes involved in isolating and developing aptamers as therapeutic compounds, using specific examples including the first aptamer therapeutic approved for use in humans (Pegaptanib or Macugen).

Epidemiology of West Nile infection in Volgograd, Russia, in relation to climate change and mosquito (Diptera: Culicidae) bionomics.

In 1999, there was the large outbreak of West Nile fever (WNF) in Southern Russia (>500 cases in the Volgograd Province). In 2000-2004, the WNF incidence rate decreased steadily to zero, but a new outbreak occurred in 2007 (64 cases). The analysis of historical climate data for Volgograd from 1900 to present showed that the years 1999 and 2007 were the hottest ones due to a very mild "winter" (Dec.

[Mosquito complex (Diptera, Culicidae) in a West Nile fever focus in the Volgograd Region. II. Host-feeding patterns of mosquitoes in different habitats].

Host preference of the mosquitoes collected in the urban and rural habitats of Volgograd and its suburbs was studied by the precipitation reaction test. Human and avian blood was detected in Cx. pipiens, Cx.

Evaluation of potential West Nile virus vectors in Volgograd region, Russia, 2003 (Diptera: Culicidae): species composition, bloodmeal host utilization, and virus infection rates of mosquitoes.

Potential West Nile virus (family Flaviviridae, genus Flavivirus, WNV) vectors were assessed during 2003 at indoor and outdoor collection sites in urban Volgograd, Russia, and in three nearby towns and surrounding rural areas. In total, 9,182 female mosquitoes comprising 13 species in six genera were collected. Relative abundance and bloodmeal host utilization differed temporarily and spatially.

Economic evaluation of Haemophilus influenzae type b vaccination in Moscow, Russian Federation.

Objective: To estimate the cost-effectiveness of providing Haemophilus influenzae type b (Hib) vaccine to children in Moscow in routine immunization services.

Methods: The incidence of Hib meningitis among children aged <5 years in Moscow was obtained from a prospective surveillance study undertaken during October 1999-September 2001, with treatment cost data collected for all cases. Sequelae in surviving children were assessed in December 2002.

Ribosomal protein L1 recognizes the same specific structural motif in its target sites on the autoregulatory mRNA and 23S rRNA.

The RNA-binding ability of ribosomal protein L1 is of profound interest since the protein has a dual function as a ribosomal protein binding rRNA and as a translational repressor binding its mRNA. Here, we report the crystal structure of ribosomal protein L1 in complex with a specific fragment of its mRNA and compare it with the structure of L1 in complex with a specific fragment of 23S rRNA determined earlier. In both complexes, a strongly conserved RNA structural motif is involved in L1 binding through a conserved network of RNA-protein H-bonds inaccessible to the solvent.

[Multilocus sequence-typing for characterization of Moscow strains of Haemophilus influenzae type b].

Haemophilius influenzae, type b (Hib) bacteria, were genotyped by multilocus sequence typing (MLST) using 5 loci (adk, fucK, mdh, pgi, recA). 42 Moscow Hib strains (including 38 isolates form cerebrospinal fluid of children, who had purulent meningitis in 1999-2001, and 4 strains isolated from healthy carriers of Hib), as well as 2 strains from Yekaterinburg were studied. In MLST a strain is characterized, by alleles and their combinations (an allele profile) referred to also as sequence-type (ST).

Structure of the L1 protuberance in the ribosome.

The L1 protuberance of the 50S ribosomal subunit is implicated in the release/disposal of deacylated tRNA from the E site. The apparent mobility of this ribosomal region has thus far prevented an accurate determination of its three-dimensional structure within either the 50S subunit or the 70S ribosome. Here we report the crystal structure at 2.

[Characteristics of antitoxic and antibacterial immune response in nontoxic forms of oropharyngeal diphtheria].

The enzyme immunoassay system (EIA) for differentiation of antibodies in therapeutic heterogeneous antitoxic serum and antibodies to Corynebacterium diphtheriae toxigenic strains in patients and carriers was developed. The use of EIA permitted the dynamic evaluation of the characteristics of humoral antitoxic and antibacterial immune response in 50 patients with the localized and disseminated forms of stomatopharyngeal diphtheria and 14 "healthy" carriers of toxigenic C. diphtheriae.

Isolation, crystallization, and investigation of ribosomal protein S8 complexed with specific fragments of rRNA of bacterial or archaeal origin.

The core ribosomal protein S8 binds to the central domain of 16S rRNA independently of other ribosomal proteins and is required for assembling the 30S subunit. It has been shown with E. coli ribosomes that a short rRNA fragment restricted by nucleotides 588-602 and 636-651 is sufficient for strong and specific protein S8 binding.

Outbreak of West Nile virus infection, Volgograd Region, Russia, 1999.

From July 25 to October 1, 1999, 826 patients were admitted to Volgograd Region, Russia, hospitals with acute aseptic meningoencephalitis, meningitis, or fever consistent with arboviral infection. Of 84 cases of meningoencephalitis, 40 were fatal. Fourteen brain specimens were positive in reverse transcriptase-polymerase chain reaction assays, confirming the presence of West Nile/Kunjin virus.

Divergence of the indole alkaloid pattern in two somatic hybrid plant cell subcultures of Rauvolfia serpentina x Rhazya stricta.

The alkaloid pattern in Rauvolfia serpentina x Rhazya stricta somatic hybrid cell subcultures R x R17 K was studied and 11 compounds were identified on the basis of their spectral data. Among them, 1,2-dehydroaspidospermidine, rhazinilam, stemmadenine and tabersonine were reported as typical of Rhazya species while vomilenine and sarpagine are characteristic of Rauvolfia alkaloid metabolism. The alkaloid pattern in R x R17 K subcultures was compared with that in the other hybrid cell subcultures (R x R17 M) which were developed from the same origin hybrid cultures but have been maintained separately for about ten years.
