Distinctive gut microbial community structure in both the wild and farmed Swan goose (Anser cygnoides).

Swan goose (Anser cygnoides) is currently one of the most popular economic wildfowl for rare birds breeding industries in several provinces of China. However, the farmed Swan geese, reared in artificial environment and fed on both natural and artificial diets, display a reduced reproductive rate compared to wild species. Little is known about the gut microbiota of this species, which could play a role in nutrient and energy metabolism, immune homeostasis and reproduction.

Studying the Effect of a Composition of the Cluster Core in High-Radiopacity Cluster Complexes of Rhenium on Their Acute Toxicity In Vivo.

An in vivo study was performed to evaluate the dependence of acute toxicity of high-radiopacity and luminescent octahedral cluster complexes of rhenium after intravenous injection on a composition of the cluster core. Changes in mouse body weight, water and food consumption, degree of intoxication, and morphological changes in the visceral organs were studied after intravenous injection of the following cluster complexes with various internal ligands (S, Se, or Te): Na4[{Re 6 Te 8 }(CN)6], Na4[{Re 6 Se 8 }(CN)6], and Na4[{Re 6 S 8 }(CN)6]. The Na4[{Re 6 S 8 } (CN)6] cluster complex was shown to be the safest for animals.

Age-Related Changes in the System Metalloproteinases/Tissue Metalloproteinase Inhibitors and Proteoglycan Components in Mouse Organs.

Activity of MMP and content of TIMP and some proteoglycan components were measured in the liver, lungs, and spleen of BALB/c mice aging 2, 6, and 12 months. The increase in the content of proteoglycan components in mouse organs was associated with age-related changes in MMP activity and TIMP-1 and TIMP-2 levels. The ratio between MMP activity and content of TIMP-1 and TIMP-2 differed in the studied organs.

Oxidized Dextran Enhances Alternative Activation of Macrophages in Mice of Opposite Lines.

Differences in peritoneal macrophage polarization in mice of opposite lines CBA and C57Bl/6 and the effects of 60 kDa oxidized dextran were studied. Macrophages of C57Bl/6 mice demonstrated a phenotype close to M1, with increasing expression of CD86 costimulatory molecule and unchanged CD206 expression in response to activation. Macrophages of CBA mice demonstrated higher plasticity in response to activating agents; expression of the markers increased irrespectively on stimulated receptor (TLR-4 or mannose receptor) and both CD86 (classical activation) and CD206 (alternative activation) increased.

Studies of Influenza A/H1N1 A/Tomsk/13/2010 Virus Topology during Development of Infectious Process in Mammals.

Influenza A/H1N1 A/Tomsk/13/2010 virus registered in Siberia in 2010 proved to be an extremely pathogenic strain. Dynamic study of the topology of this influenza virus strain in the lungs, liver, kidneys, lymph nodes, and great vessels of infected mice was carried out. Influenza A virus was detected by immunohistochemical methods in cells of different histogenesis in all the studied organs throughout the observation period (days 1-30 postinfection), which indicated effective replication and long persistence of influenza A/H1N1 A/Tomsk/13/2010 virus in mammalian cells.

In Vitro Study of Cytophysiological Characteristics of Multinuclear Macrophages from Intact and BCG-Infected Mice.

Peritoneal macrophages were isolated from intact and BCG-infected BALB/c mice and explanted in vitro. Multinuclear macrophages formed in these cultures differed by the number of nuclei, expression of apoptosis inductors and regulators (TNF-α, p53 protein, caspase 3, and Bcl-2 protein), and cytophysiological characteristics (phagocytic activity, ROS generation, and antimycobacterial properties). Our results indicate that the formation of multinuclear macrophages is accompanied by induction of apoptosis (p53 signaling pathway) and appearance of multinuclear macrophage-derived cells characterized by high phagocytic and antimycobacterial activity.

Aim: To examine the incidence of polymorbidity (PM) and changes in its rates in 2003 to 2011 in cardiac and gastroenterologic patients living in the Novosibirsk Region and the Republic of Sakha (Yakutia) in accordance with gender, occupation, and residence.

Subjects And Methods: The dynamics of PM rates was analyzed in 13 496 patients who had been examined and treated at the Cardiology and Gastroenterology Departments, Therapeutic Clinic, Research Institute of Experimental and Clinical Medicine (Novosibirsk), 2003-2011. The study used an archival research method and a statistical analysis of all nosological entities, groups, and classes in ICD-10, regardless of whether the diagnosis was primary or concurrent.

Dynamic Structure of Proteoglycans/Glycosaminoglycans in the Lungs of Mice with Chronic Granulomatous Inflammation.

Structure of proteoglycans in the lungs and total glycosaminoglycan content in blood serum were studied on mouse model of BCG-induced granulomatous inflammation in mice (without destructive processes in the lung parenchyma and granulomas). The maximum level of sulfated glycosaminoglycans in the lungs was detected on postinfection day 30 and was related to their involvement in initiation granulomogenesis and development of granulomas. The maximum level of total glycosaminoglycans in mouse serum on postinfection day 90 coincided with minimum level of sulfated glycosaminoglycans in the lungs.

High-throughput sequencing reveals the core gut microbiome of Bar-headed goose (Anser indicus) in different wintering areas in Tibet.

Elucidating the spatial dynamic and core gut microbiome related to wild bar-headed goose is of crucial importance for probiotics development that may meet the demands of bar-headed goose artificial breeding industries and accelerate the domestication of this species. However, the core microbial communities in the wild bar-headed geese remain totally unknown. Here, for the first time, we present a comprehensive survey of bar-headed geese gut microbial communities by Illumina high-throughput sequencing technology using nine individuals from three distinct wintering locations in Tibet.

Adaptation of influenza A(H1N1)pdm09 virus in experimental mouse models.

In the present study, three mouse-adapted variants of influenza A(H1N1)pdm09 virus were obtained by lung-to-lung passages of BALB/c, C57BL/6z and CD1 mice. The significantly increased virulence and pathogenicity of all of the mouse-adapted variants induced 100% mortality in the adapted mice. Genetic analysis indicated that the increased virulence of all of the mouse-adapted variants reflected the incremental acquisition of several mutations in PB2, PB1, HA, NP, NA, and NS2 proteins.

Experimental infection and pathology of clade 2.2 H5N1 virus in gulls.

During 2006, H5N1 HPAI caused an epizootic in wild birds, resulting in a die-off of Laridae in the Novosibirsk region at Chany Lake. In the present study, we infected common gulls (Larus canus) with a high dose of the H5N1 HPAI virus isolated from a common gull to determine if severe disease could be induced over the 28 day experimental period. Moderate clinical signs including diarrhea, conjunctivitis, respiratory distress and neurological signs were observed in virus-inoculated birds, and 50% died.

Effect of acute systemic hypoxia on human cutaneous microcirculation and endothelial, sympathetic and myogenic activity.

The regulation of cutaneous vascular tone impacts vascular vasomotion and blood volume distribution as a challenge to hypoxia, but the regulatory mechanisms yet remain poorly understood. A skin has a very compliant circulation, an increase in skin blood flow results in large peripheral displacement of blood volume, which could be controlled by local and systemic regulatory factors. The aim of this study was to determine the acute systemic hypoxia influence on blood flow in skin, local regulatory mechanism fluctuations and changes of systemic hemodynamic parameters.
