Związek między polimorfizmem rs7903146 genu TCF7L2 a nefropatią cukrzycową nie jest niezależny od cukrzycy typu 2 — badanie populacji Indii Południowych i metaanaliza
No full textDiabetic nephropathy (DN) is a chronic microangiopathic complication of both type 1 (T1DM) and type 2 diabetes mellitus (T2DM). The TCF7L2 gene has been reported to be associated with type 2 diabetes risk. We aimed to investigate the impact of TCF7L2 gene on the susceptibility of T2DM and DN in a south Indian population. Plus to evaluate the association of rs7903146 in the TCF7L2 gene with T2DM in the Indian population. The subjects recruited for this included 55 diabetic cases with diabetic nephropathy, 68 diabetic cases without nephropathy, and 82 non-diabetic healthy controls. Genomic DNA was isolated from blood and genotyping of TCF7L2 rs7903146 was performed by PCR-RFLP analysis. A literature survey was carried out into the effect of rs7903146 on genetic susceptibility to T2DM in Indian populations and we then performed a meta-analysis in order to evaluate its association with T2DM. Analysis of TCF7L2 rs7903146 in normal controls and diabetics with or without nephropathy demonstrated that the ‘T’ allele is associated with both diabetes (p = 0.049) and DN (p = 0.024), but this association is not independent of T2DM. Meta-analysis showed that the mutant allele and genotypes are associated with T2DM in Indian populations. In summary, a significant association exists between the ‘T’ allele and DN, but this association is not independent of T2DM. Pooled meta-analysis of studies on rs7903146 and T2DM confirmed that rs7903146 is significantly associated with susceptibility to T2DM in Indian populations.

Gen TCF7L2 jest związany z ryzykiem cukrzycy typu 2. Badanie przeprowadzono w celu dokonania oceny wpływu genu TCF7L2 na podatność na zachorowanie na T2DM i DN w populacji Indii Południowych oraz oceny związku między występowaniem polimorfizmu rs7903146 genu TCF7L2 i T2DM w populacji południowej części Indii. Do badania włączono 55 przypadków chorych na cukrzycę z nefropatią cukrzycową, 68 przypadków cukrzycy bez nefropatii i 82 osoby niechorujące na cukrzycę jako grupę kontrolną. Genomowe DNA izolowano z krwi i przeprowadzono genotypowanie polimorfizmu rs7903146 genu TCF7L2 metodą analizy PCR-RFLP. Przeprowadzono również przegląd literatury pod kątem danych dotyczących wpływu występowania polimorfizmu rs7903146 na genetyczną podatność na T2DM w populacji hinduskiej, a następnie przeprowadzono metaanalizę w celu oceny jego związku z T2DM. Analiza polimorfizmu rs7903146 genu TCF7L2 u zdrowych osób z grupy kontrolnej oraz u chorych na cukrzycę z nefropatią i bez nefropatii wykazała, że allel T jest związany zarówno z cukrzycą (p = 0,049), jak i DN (p = 0,024), jednak ten związek nie jest niezależny od T2DM. Metaanaliza wykazała, że zmutowane allele i genotypy są związane z T2DM w populacji hinduskiej. Podsumowując, istnieje istotny związek między allelem T i DN, jednak związek ten nie jest niezależny od T2DM. Metaanaliza danych z badań dotyczących polimorfizmu rs7903146 i T2DM potwierdziła, że obecność polimorfizmu rs7903146 jest istotnie związana z podatnością na zachorowanie na T2DM w populacji hinduskiej.

In Defense of Revolutionary Socialism: The Implications of Bhaskar Sunkara’s The Socialist Manifesto
No full textThis review of Bhaskar Sunkara’s The Socialist Manifesto locates the book within socialist debates about revolutionary praxis and the limits of reform versus revolution. The reviewer argues that the book has been accused, both fairly and unfairly, as “socialism without revolution,” an argument that can only be understood by delving more deeply into the positions advocated by the author. While Sunkara does in fact advance a “revolutionary socialism” in terms of concrete policy proposals, it is fair to ask critical questions about whether or not his limited interrogation of capitalist power is compatible with his self-professed goals
BARON: Base-Station Authentication Through Core Network for Mobility Management in 5G Networks
No full textFifth-generation (5G) cellular communication networks are being deployed on applications beyond mobile devices, including vehicular networks and industry automation. Despite their increasing popularity, 5G networks, as defined by the Third Generation Partnership Project (3GPP), have been shown to be vulnerable against fake base station (FBS) attacks. An adversary carrying out an FBS attack emulates a legitimate base station by setting up a rogue base station. This enables the adversary to control the connection of any user equipment that (inadvertently) connects with the rogue base station. Such an adversary can gather sensitive information belonging to the user. While there is a large body of work focused on the development of tools to detect FBSs, the user equipment will continue to remain vulnerable to an FBS attack. In this paper, we propose BARON, a defense methodology to enable user equipment to determine whether a target base station that it is connecting to is legitimate or rogue. BARON accomplishes this by ensuring that the user receives an authentication token from the target base station which can be computed only by a legitimate and trusted entity. As a consequence, receiving such an authentication token from a base station ensures legitimacy of the base station. We evaluate BARON through extensive experiments on the handover process between base stations in 5G networks. Our experimental results show that BARON introduces an overhead of less than 1% during handover completion, which is 10000× lower than the overhead reported by a state-of-the-art method. BARON is also effective in thwarting an FBS attack and quickly recovering connection to a legitimate base station. Cyber Securit
Residual stress gradient and relaxation upon fatigue deformation of diamond-like carbon coated aluminum alloy in air and methanol environments
No full textAmorphous diamond-like carbon coating (DLC) of 2 μm in thickness was deposited over the aluminum alloy substrate using magnetron sputtering deposition technique. In order to understand the efficacy of coating deposition, coated specimens were subjected to rotating bending fatigue in air and methanol environments respectively. Raman spectroscopy was used in conjunction with grazing incidence X-diffraction technique to obtain depth-resolved residual stress gradients of coated-aluminum substrate. The residual stress generated due to coating deposition was calculated using Raman spectroscopy and it was −1.13 ± 0.16 GPa (compressive in nature). Furthermore, Raman spectroscopy was utilized for the quantification of stress relaxation upon fatigue loading in air and methanol environments. It was observed that the irrespective of the testing environment, good correlation exists between the stress relaxation magnitude and number of cycles endured before failure
