Wild reindeer (Rangifer tarandus L.) resources use in the Taimyr peninsula: Aspects of the principle of ecological law
Rapid development of modern industry on the Taimyr peninsula together with global changes of environmental conditions and great anthropogenic pressure have caused observable disruption of some Arctic and sub Arctic tundra ecosystems. These changes have several effects on the animal populations, Wild reindeer (Rangifer tarandus L.) in particular, that are the resources of living for the indigenous people of the Taimyr peninsula. Many problems are eliminated by existing environmental, health, housing and civil rights laws, research and educational activities. In future, they should be developed and advanced so that R. tarandus resources could be balanced according to the indigenous people demands

Assessing Sustainable Development Potential of Rural Territories
The paper presents an analysis of the resource potential of sustainable rural development in two regions of the Russian Federation, namely, the Altay territory (which is an agricultural region) and the Kemerovo region (an industrial region with an auxiliary role of agriculture). Agriculture is predominantly developing in agricultural areas represented by a comprehensive complex of resources. The lack of systemic approach in agricultural development has led to the irrational distribution of productive forces, inferior development of social and household infrastructure, and other imbalances having adverse effects on agricultural economic performance and living conditions in rural areas. To address this problem, the authors have developed an original method of resource potential analysis for rural areas, including a combination of economic, social, and infrastructure indicators.
 
PALB2 mutations in German and Russian patients with bilateral breast cancer
Since germline mutations in the PALB2 (Partner and Localizer of BRCA2) gene have been identified as breast cancer (BC) susceptibility alleles, the geographical spread and risks associated with PALB2 mutations are subject of intense investigation. Patients with bilateral breast cancer constitute a valuable group for genetic studies. We have thus scanned the whole coding region of PALB2 in a total of 203 German or Russian bilateral breast cancer patients using an approach based on high-resolution melting analysis and direct sequencing of genomic DNA samples. Truncating PALB2 mutations were identified in 4/203 (2%) breast cancer patients with bilateral disease. The two nonsense mutations, p.E545X and p.Q921X, have not been previously described whereas the two other mutations, p.R414X and c.509_510delGA, are recurrent. Our results indicate that PALB2 germline mutations account for a small, but not negligible, proportion of bilateral breast carcinomas in German and Russian populations
TOPBP1 missense variant Arg309Cys and breast cancer in a German hospital-based case-control study
The DNA double strand break repair gene TOPBP1 has been suggested as a breast cancer susceptibility gene and a missense variant Arg309Cys was observed at elevated frequency in familial breast cancer cases compared to healthy controls from Finland. We found the Arg309Cys allele at a 13% carrier frequency in a hospital-based series of 1064 German breast cancer patients and at a 14% carrier frequency in 1014 population controls (OR 0.89, 95%CI 0.69-1.15; p = 0.4). Arg309Cys carriers were not enriched among patients with a family history of breast cancer (OR = 0.87, 95%CI 0.53-1.43, p = 0.6) and were slightly underrepresented in patients with bilateral disease (OR = 0.49, 95%CI = 0.24-0.99; p = 0.047). In the latter group, the mean age at diagnosis was 62 years in carriers and 54 years in non-carriers (p = 0.004). We conclude that there is no evidence for the TOPBP1*Arg309Cys variant to confer an increased risk for breast cancer in the German population
Prostate Cancer Risk Is not Altered by TP53AIP1 Germline Mutations in a German Case-Control Series
Prostate cancer susceptibility has previously been associated with truncating germline variants in the gene TP53AIP1 (tumor protein p53 regulated apoptosis inducing protein 1). For two apparently recurrent mutations (p.Q22fs and p.S32X) a remarkable OR of 5.1 was reported for prostate cancer risk. Since these findings have not been validated so far, we genotyped p.Q22fs and p.S32X in two German series with a total of 1,207 prostate cancer cases and 1,495 controls. The truncating variants were not significantly associated with prostate cancer in none of the two cohorts, nor in the combined analysis [odds ratio (OR) = 1.16; 95% confidence interval (CI 95%) = 0.62–2.15; p = 0.66]. Carriers showed no significant differences in family history of prostate cancer, age at diagnosis, Gleason score or PSA at diagnosis when compared to non-carrier prostate cancer cases. The large sample size of the combined cohort rejects a high-risk effect greater than 2.2 and indicates a limited role of TP53AIP1 in prostate cancer predisposition
Shared genetics underlying epidemiological association between endometriosis and ovarian cancer
Epidemiological studies have demonstrated associations between endometriosis and certain histotypes of ovarian cancer, including clear cell, low-grade serous and endometrioid carcinomas. We aimed to determine whether the observed associations might be due to shared genetic aetiology. To address this, we used two endometriosis datasets genotyped on common arrays with full-genome coverage (3194 cases and 7060 controls) and a large ovarian cancer dataset genotyped on the customized Illumina Infinium iSelect (iCOGS) arrays (10 065 cases and 21 663 controls). Previous work has suggested that a large number of genetic variants contribute to endometriosis and ovarian cancer (all histotypes combined) susceptibility. Here, using the iCOGS data, we confirmed polygenic architecture for most histotypes of ovarian cancer. This led us to evaluate if the polygenic effects are shared across diseases. We found evidence for shared genetic risks between endometriosis and all histotypes of ovarian cancer, except for the intestinal mucinous type. Clear cell carcinoma showed the strongest genetic correlation with endometriosis (0.51, 95% CI = 0.18-0.84). Endometrioid and low-grade serous carcinomas had similar correlation coefficients (0.48, 95% CI = 0.07-0.89 and 0.40, 95% CI = 0.05-0.75, respectively). High-grade serous carcinoma, which often arises from the fallopian tubes, showed a weaker genetic correlation with endometriosis (0.25, 95% CI = 0.11-0.39), despite the absence of a known epidemiological association. These results suggest that the epidemiological association between endometriosis and ovarian adenocarcinoma may be attributable to shared genetic susceptibility loci
Development of the Arctic reindeer industry from the perspective of Sino-Russian green biomanufacturing cooperation
Russia’s reindeer population accounts for two thirds of the world’s total. There is a strong and resilient population of reindeer on the tundra, and reindeer herders inherit and transmit the unique culture of the north. Reindeer products have become the subject of innovative developments in the biopharmaceutical and healthcare products industry owing to their unique raw material properties. Because deer antlers and blood are widely used in traditional Chinese medicine, significant quantities of Arctic reindeer products are likely to be sold in China. Strengthening understanding of the Russian Arctic reindeer industry will help Chinese companies invest in the Russian Arctic, promote Sino-Russian Arctic cooperation on green biomanufacturing, and lead to the development of new products that promote human health
