Lifestyle intervention in individuals with impaired glucose regulation affects Caveolin-1 expression and DNA methylation
© 2020, © 2020 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group. Aims: We investigated whether a lifestyle intervention could influence expression and DNA methylation of diabetes-related genes in patients with impaired glucose regulation (IGR), the results were compared to bariatric surgery, considering it an intensive change. Methods: Twenty participants with IGR had adipose tissue biopsy and blood collected pre- and post-lifestyle (6 months) intervention; 12 obese patients had subcutaneous fat taken before and after bariatric surgery. RNA/DNA was extracted from all samples and underwent qPCR. DNA was bisulphite converted and 12 CpG sites of Caveolin-1 (CAV1) promoter were pyrosequenced. Results: lifestyle intervention resulted in opposite direction changes in fat tissue and blood for CAV1 expression and DNA methylation and these changes were correlated between tissues, while no significative differences were found in CAV1 expression after bariatric surgery. Conclusions: Our findings suggest a role for CAV1 in modulating adipocyte function as a consequence of lifestyle changes, as exercises and diet. These results may provide insights into new therapeutic targets for diabetes prevention
SMART TRAFFIC CONTROL BARRICADE SYSTEM
At present traffic management is a big challenge and plays a vital role in moving the vehicles from one corner of the city to the other. This system not only controls the traffic signals but also it reduces violating traffic rules and accidents. Here when the red light signal is ON there will be a servomotor which pops up barricade from ground level. It applies one special condition in the road by placing a barricade before the zebra crossing which will stop the vehicles when the signal red light is ON. The barricade will automatically pops up on the vehicle stopping mark, when the signal leaves it pops down to the ground. For ambulance, it is having a special feature that there will be an RFID tag which can sense about its arrival. For this reason the RFID reader is fixed to road. During the red signal, when the ambulance needs to pass at that time RFID reads the tag and changes red light to green light in traffic signal through GSM where RFID reader card number is stored in control system. So the barricade will pop down to ground and the other three ways are stopped with red signal light so that the ambulance can easily pass through the way by these one can save someone's life. This project work is carried out by using IOT technology
Structural and Functional Characteristics of miRNAs in Five Strategic Millet Species and Their Utility in Drought Tolerance
Millets are the strategic food crops in arid and drought-prone ecologies. Millets, by virtue
of nature, are very well-adapted to drought conditions and able to produce sustainable
yield.Millets have important nutrients that can help preventmicro-nutrientmalnutrition. As
a result of the adverse effect of climate change and widespread malnutrition, millets have
attained a strategic position to sustain food and nutritional security. Although millets can
adapt well to the drought ecologies where other cereals fail completely, the yield level is
very low under stress. There is a tremendous opportunity to increase the genetic potential
of millet crops in dry lands when the genetics of the drought-tolerance mechanism is fully
explained. MicroRNAs (miRNAs) are the class of small RNAs that control trait expression.
They are part of the gene regulation but little studied in millets. In the present study,
novel miRNAs and gene targets were identified from the genomic resources of pearl
millet, sorghum, foxtail millet, finger millet, and proso millet through in silico approaches.
A total of 1,002 miRNAs from 280 families regulating 23,158 targets were identified
using different filtration criteria in five millet species. The unique as well as conserved
structural features and functional characteristics of miRNA across millets were explained.
About 84miRNAs were conserved acrossmillets in different species combinations, which
explained the evolutionary relationship of the millets. Further, 215 miRNAs controlling
155 unique major drought-responsive genes, transcription factors, and protein families
revealed the genetics of drought tolerance that are accumulated in the millet genomes.
The miRNAs regulating the drought stress through specific targets or multiple targets
showed through a network analysis. The identified genes regulated by miRNA genes
could be useful in developing functional markers and used for yield improvement under
drought in millets as well as in other crops
ANALYSIS AND STRUCTURAL OPTIMIZATION OF 5 TON H-FRAME HYDRAULIC PRESS
Abstract Using the optimum resources possible in designing the hydraulic presses frame can effect reduction in the cost of the hydraulic presses. By optimizing the weight of material utilized for building the structure. An attempt has been made in this direction to reduce the volume of material. So here we consider an industrial application project consisting of mass minimization of H-frame type hydraulic press. This press has to compensate the forces acting on the working plates and has to fulfill certain critical constraints. ANSYS has been used for this analysis the main aim is to reduce the cost of the Hydraulic presses without compromising on the quality of the output. With regarding to design specification, stress distribution, deflection, and cost, are focused on optimized design. The methodology followed in this work is comparison of stresses induced in machine for different thickness used for construction of frame and column of the Hframe type hydraulic press.
Development of a new AgriSeq 4K mid-density SNP genotyping panel and its utility in pearl millet breeding
Pearl millet is a crucial nutrient-rich staple food in Asia and Africa and adapted
to the climate of semi-arid topics. Since the genomic resources in pearl millet
are very limited, we have developed a brand-new mid-density 4K SNP panel
and demonstrated its utility in genetic studies. A set of 4K SNPs were mined
from 925 whole-genome sequences through a comprehensive in-silico
pipeline. Three hundred and seventy-three genetically diverse pearl millet
inbreds were genotyped using the newly-developed 4K SNPs through the
AgriSeq Targeted Genotyping by Sequencing technology. The 4K SNPs were
uniformly distributed across the pearl millet genome and showed considerable
polymorphism information content (0.23), genetic diversity (0.29), expected
heterozygosity (0.29), and observed heterozygosity (0.03). The SNP panel
successfully differentiated the accessions into two major groups, namely B
and R lines, through genetic diversity, PCA, and structure models as per their
pedigree. The linkage disequilibrium (LD) analysis showed Chr3 had higher LD
regions while Chr1 and Chr2 had more low LD regions. The genetic divergence
between the B- and R-line populations was 13%, and within the sub-population
variability was 87%. In this experiment, we have mined 4K SNPs and optimized
the genotyping protocol through AgriSeq technology for routine use, which is cost-effective, fast, and highly reproducible. The newly developed 4K middensity
SNP panel will be useful in genomics and molecular breeding
experiments such as assessing the genetic diversity, trait mapping, backcross
breeding, and genomic selection in pearl millet
Genetically defined favourable adiposity is not associated with a clinically meaningful difference in clinical course in people with type 2 diabetes but does associate with a favourable metabolic profile.
This is the final version. Available from Wiley via the DOI in this record.DATA AVAILABILITY STATEMENT
We used patient-level data which was fully anonymised prior
to analysis. Any requests for access to the Salford data should
be made to Dr Adrian Heald.AIMS: Change in weight, HbA1c , lipids, blood pressure and cardiometabolic events over time is variable in individuals with type 2 diabetes. We hypothesised that people with a genetic predisposition to a more favourable adiposity distribution could have a less severe clinical course/progression. METHODS: We involved people with type 2 diabetes from two UK-based cohorts: 11,914 individuals with GP follow-up data from the UK Biobank and 723 from Salford. We generated a 'favourable adiposity' genetic score and conducted cross-sectional and longitudinal studies to test its association with weight, BMI, lipids, blood pressure, medication use and risk of myocardial infarction and stroke using 15 follow-up time points with 1-year intervals. RESULTS: The 'favourable adiposity' genetic score was cross-sectionally associated with higher weight (effect size per 1 standard deviation higher genetic score: 0.91 kg [0.59,1.23]) and BMI (0.30 kg/m2 [0.19,0.40]), but higher high-density lipoprotein (0.02 mmol/L [0.01,0.02]) and lower triglycerides (-0.04 mmol/L [-0.07, -0.02]) in the UK Biobank at baseline, and this pattern of association was consistent across follow-up. There was a trend for participants with higher 'favourable adiposity' genetic score to have lower risk of myocardial infarction and/or stroke (odds ratio 0.79 [0.62, 1.00]) compared to those with lower score. A one standard deviation higher score was associated with lower odds of using lipid-lowering (0.91 [0.86, 0.97]) and anti-hypertensive medication (0.95 [0.91, 0.99]). CONCLUSIONS: In individuals with type 2 diabetes, having more 'favourable adiposity' alleles is associated with a marginally better lipid profile long-term and having lower odds of requiring lipid-lowering or anti-hypertensive medication in spite of relatively higher adiposity.Diabetes UKEuropean Research CouncilMedical Research CouncilResearch Englan
Role of PCSK5 Expression in Mouse Ovarian Follicle Development: Identification of the Inhibin α- and β-Subunits as Candidate Substrates
Inhibin and activin are essential dimeric glycoproteins belonging to the transforming growth factor-beta (TGFβ) superfamily. Inhibin is a heterodimer of α- and β-subunits, whereas activin is a homodimer of β-subunits. Production of inhibin is regulated during the reproductive cycle and requires the processing of pro-ligands to produce mature hormone. Furin is a subtilisin-like proprotein convertase (proconvertase) that activates precursor proteins by cleavage at basic sites during their transit through the secretory pathway and/or at the cell surface. We hypothesized that furin-like proconvertases are central regulators of inhibin α- and β-subunit processing within the ovary. We analyzed the expression of the proconvertases furin, PCSK5, PCSK6, and PCSK7 in the developing mouse ovary by real-time quantitative RT-PCR. The data showed that proconvertase enzymes are temporally expressed in ovarian cells. With the transition from two-layer secondary to pre-antral follicle, only PCSK5 mRNA was significantly elevated. Activin A selectively enhanced expression of PCSK5 mRNA and decreased expression of furin and PCSK6 in cultured two-layer secondary follicles. Inhibition of proconvertase enzyme activity by dec-RVKR-chloromethylketone (CMK), a highly specific and potent competitive inhibitor of subtilisin-like proconvertases, significantly impeded both inhibin α- and β-subunit maturation in murine granulosa cells. Overexpression of PC5/6 in furin-deficient cells led to increased inhibin α- and βB-subunit maturation. Our data support the role of proconvertase PCSK5 in the processing of ovarian inhibin subunits during folliculogenesis and suggest that this enzyme may be an important regulator of inhibin and activin bioavailability

Indigenous plants promote insect biodiversity in urban greenspaces
The contribution of urban greenspaces to support biodiversity and provide benefits for people is increasingly recognized. However, ongoing management practices favor vegetation oversimplification, often limiting greenspaces to lawns and tree canopy rather than multi-layered vegetation that includes under- and midstorey, and the use of nonnative species. These practices hinder the potential of greenspaces to sustain indigenous biodiversity, particularly for taxa like insects that rely on plants for food and habitat. Yet, little is known about which plant species may maximize positive outcomes for taxonomically and functionally diverse insect communities in greenspaces. Additionally, while cities are expected to experience high rates of introductions, quantitative assessments of the relative occupancy of indigenous vs. introduced insect species in greenspace are rare, hindering understanding of how management may promote indigenous biodiversity while limiting the establishment of introduced insects. Using a hierarchically replicated study design across 15 public parks, we recorded occurrence data from 552 insect species on 133 plant species, differing in planting design element (lawn, midstorey, and tree canopy), midstorey growth form (forbs, lilioids, graminoids, and shrubs) and origin (nonnative, native, and indigenous), to assess (1) the relative contributions of indigenous and introduced insect species and (2) which plant species sustained the highest number of indigenous insects. We found that the insect community was overwhelmingly composed of indigenous rather than introduced species. Our findings further highlight the core role of multi-layered vegetation in sustaining high insect biodiversity in urban areas, with indigenous midstorey and canopy representing key elements to maintain rich and functionally diverse indigenous insect communities. Intriguingly, graminoids supported the highest indigenous insect richness across all studied growth forms by plant origin groups. Our work highlights the opportunity presented by indigenous understory and midstorey plants, particularly indigenous graminoids, in our study area to promote indigenous insect biodiversity in urban greenspaces. Our study provides a blueprint and stimulus for architects, engineers, developers, designers, and planners to incorporate into their practice plant species palettes that foster a larger presence of indigenous over regionally native or nonnative plant species, while incorporating a broader mixture of midstorey growth forms
