Bar-headed goose (Anser indicus), a species endemic to Asia, has become one of the most popular species in recent years for rare bird breeding industries in several provinces of China. There has been no information on the gut metagenome configuration in both wild and artificially reared Bar-headed geese, even though the importance of gut microbiome in vertebrate nutrient and energy metabolism, immune homeostasis and reproduction is widely acknowledged. In this study, metagenomic methods have been used to describe the microbial community structure and composition of functional genes associated with both wild and artificially reared Bar-headed goose. Taxonomic analyses revealed that Firmicutes, Proteobacteria, Actinobacteria and Bacteroidetes were the four most abundant phyla in the gut of Bar-headed geese. Bacteroidetes were significantly abundant in the artificially reared group compared to wild group. Through functional profiling, we found that artificially reared Bar-headed geese had higher bacterial gene content related to carbohydrate transport and metabolism, energy metabolism and coenzyme transport, and metabolism. A comprehensive gene catalog of Bar-headed geese metagenome was built, and the metabolism of carbohydrate, amino acid, nucleotide, and energy were found to be the four most abundant categories. These results create a baseline for future Bar-headed goose microbiology research, and make an original contribution to the artificial rearing of this bird.

Linear dextrans are often proposed as drug delivery systems with milder adverse effects and lower effective drug concentrations. Linear dextrans are polysaccharides that can potentially be used to load macrophages with drugs to transport them to a site of inflammation. Recently, it was reported that dextrans may exert a protective effect vis--vis drug cytotoxicity and during wound healing. The aim of the current work was to evaluate molecular mechanisms of action of dextrans that may be relevant to the cytoprotective effects.We determined the effect of treatment with 40- or 70-kDa dextran on production of reactive oxygen species, lipid peroxidation, and lysosomal pH in the J774 macrophage cell line. In addition, induction of Keap1/Nrf2/ARE and autophagic activity were evaluated.Dextrans of both molecular weights protected the cells from oxidative stress induced by cumene hydroperoxide and from lysosomal stress induced by ammonium chloride. The effect was associated with induction of the Keap1/Nrf2/ARE signaling pathway. Furthermore, dextran stimulated autophagy in a dose-dependent manner but inhibited the autophagosome-lysosome fusion in a time-dependent manner.This study shows possible cytoprotective effects of dextran under oxidative stress, and these findings may be used for the development of novel (dextran-based) drug delivery approaches.

Many plant phenols (stilbenes, curcumins, catechins, flavonoids, etc.) are effective antioxidants and protect cells during oxidative stress. Extensive clinical studies on the potential of phenolic compounds for treatment of cardiovascular, neurodegenerative, oncological, and inflammatory diseases are now being conducted. In addition to direct antioxidant effect, plant phenols may provide a protective effect via activation of the Keap1/Nrf2/ARE redox-sensitive signaling system and regulation of autophagy. In this review, mechanisms of effects of the most common plant phenols on autophagy are presented.

The complete genome sequence was determined for avian paramyxovirus (APMV-6) serotype 6 strain teal/Chany/455/2009, isolated from a teal (Anas crecca) in Siberia. Siberia is crossed by four major migration flyways and represents the major breeding area for many wild bird species in the Palearctic. Strain teal/Chany/455/2009 is genetically closely related to Kazakh and Chinese strains and belongs to the genetic group of duck/Hong Kong/18/199/77-like APMV-6 viruses. We show that the virus has low pathogenic potential according to genetic markers and animal model experiments.

Blood levels of glucose and immunoreactive insulin were assessed in women with android and gynoid types of obesity or normal body weight (control group) in the dynamics of oral glucose tolerance test in the morning and in the evening. In the control group, the mean concentrations of glucose and immunoreactive insulin were significantly higher in the evening at all test terms (0, 60 and 120 min), which is indicative of physiological insulin resistance in the evening. In the group of women with gynoid obesity, no difference in the levels of glucose and immunoreactive insulin was revealed in the morning and evening tests, but in the evening tests, glucose (60 and 120 min) and immunoreactive insulin (120 min) levels were lower than in the control group. In the group of women with android obesity, the evening glucose level on minutes 60 and 120 of the test was higher than in the morning, but immunoreactive insulin did not vary throughout the day and on minutes 60 and 120 it surpassed the corresponding parameter in the control group by 2-4 times. In case of gynoid obesity, glucose load was followed by hyperinsulinemia and hypoglycemia; in android obesity, it was followed by hyperinsulinemia, hyperglycemia, and insulin resistance irrespective of the time of the day.

to evaluate the efficiency of decimeter wave therapy and halotherapy, which were additionally added to basic therapy, in patients with chronic obstructive pulmonary disease (COPD) concurrent with hypertension at the inpatient stage.36 patients aged 20 to 75 years with Stages I-II COPD concurrent with Stages I-II, first-second grade hypertension were examined and treated. The clinical examination included collection of complaints and medical history data, clinical laboratory and instrumental (electrocardiography, spirography) studies, and health-related quality of life (using the SF-36 questionnaire). The patients were randomized into two groups: a study group and a comparison group. The study group patients received decimeter wave therapy and halotherapy in addition to basic drug treatment; the comparison patients had basic drug therapy.Pre- and postoperative comparative analysis of the major clinical manifestations of comorbidities revealed more pronounced positive changes with the lower rate of clinical manifestations in the study group. It was also observed to have a more marked reduction in blood pressure (BP) with its goal levels achieved. The mean pulse BP decreased by 28% in the study group (p=0.000005) and did not statistically reduced in the comparison group. In the study group patients, the integral quality-of-life indicator after a package of medical rehabilitation measures became statistically significantly higher by 35%. This indicator in the comparison group was statistically significantly unchanged.The directionality of the proposed rehabilitation complex towards the common pathogenetic components of the development and progression of COPD and hypertension, as well as the high efficiency of the complex justify its appropriate inclusion in the combination treatment and rehabilitation of this category of patients.

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. Macrophage response to addition of oxidized dextran (60 kDa) to the culture medium could be characterized as potentiation of their alternative activation: expression of CD86 in CBA mice in response to LPS and LPS+IL-4 and in C57Bl/6 mice in response to IFN- and LPS+IFN- decreased, while expression of CD206 by intact macrophages of CBA mice and by macrophages stimulated by IFN- and IL-4 increased under the effect of 60 kDa oxidized dextran.

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.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.There was an increase in PM rates among the therapeutic clinics patients of regardless of their gender and occupation. There were gender differences in the incidence of PM: its higher rates were noted in the women than those in the men among both the residents of the Novosibirsk Region and those of the Republic of Sakha (Yakutia). More significantly higher PM rates were registered in the male inhabitants of the Novosibirsk Region. There were also regional differences in the incidence of PM: its rates proved to be higher in the patients in the Republic of Sakha (Yakutia) than in those in the Novosibirsk Region in 2003-2007. At the same time, the growth rates for PM were more marked in the patients in the Novosibirsk region than in those in the Republic of Sakha (Yakutia); these differences levelled off in subsequent years.The findings indicate a pronounced increase in the incidence of PM in cardiac and gastroentorologic patients and determine a need to keep in mind the influence of gender, social, and regional factors on its development in order to create and improve a primary and secondary prevention, diagnosis and treatment system.

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. This blood/lungs ratio of glycosaminoglycans can be related to the prevalence of low-molecular-weight hyaluronan fragments promoting inflammation and fibrosis in the lungs observed at the end of the experiment (postinfection day 180).
