    Background: Dementia affected about 46 million people in 2015and this number will roughly triple within the next 40 years. In 2011 Alzheimer's Disease International argue that dementia has become one of the most urgent health and social care challenges of the 21st century and its potential effect on economies around the world is attracting global attention. Predicting dementia in the early stages would be essential for better treatment before significant brain damage occurs. Current difficulty is the lack of specific biomarkers. In some previous studies electroencephalography (EEG) have shown the capability to identify dementia early and even classify the degree of its severity at a lower cost for mass screening. The aim and objective of this study was to EEG changes in vascular dementia and Alzheimer's Disease Related Dementias (ADRD) or dementia where no cause is identifiable, to measure severity of dementia by using DSR scale in different subjects and to correlate DSRS with EEG findings.Methods: Study sample was the 40 patients in each three groups- Dementia patients without any known cause of dementia or Alzheimer's Disease Related Dementias (ADRD), Vascular dementia (VaD) patients and Controls (age and sex matched subjects scoring more than the cut of score on dementia Scale). Written informed consent will be taken after explaining the objectives and procedure of study in detail. EEG were recorded in eyes closed, on intermittent photic stimulation and hyperventilation, only eyes closed data was used in study and these data were entered in excel sheet and analyzed using SPSS Software, appropriate statistical test was applied wherever necessary.Results: Participants with VaD have theta waves while ADRD group have delta waves preponderance as compare to control.Conclusions: EEG can have additive value in diagnosing VaD as well as it alone can be helpful in differentiating healthy individuals from dementia patients

    Presently green fodder availability is 64.66 M tons and dry fodder (64.23 M tons.) in Uttar Pradesh, India., the green fodder deficit is 28.3% and dry fodder surplus by 14.1% respectively. Whereas, in Uttrakhand. Green fodder availability is 4.07 M tons and dry fodder 2.83 M tons, green fodder deficit is 48.1% and dry fodder 42.1%. There are many limitations affecting the forage production such as small holding of farmers and preferential need of food grains crops, limited availability of quality seed of improved varieties of fodder crops, low priority for investment in fodder production by the farmers. There is varied problem soils (acid, salt affected and water logged) prevailing in the area, lack of post harvest management for surplus fodder, no priority for fodder seed production by the farmers/seed producing agencies, no MSP for any of the fodder crops and lack of mechanization in fodder farming. Therefore, Nation Initiative on Fodder Technology Demonstrations will focus on increasing productivity through adoption of improved and appropriate technology best suited to the agro-climatic conditions in the zone in both arable and non-arable land. The objective of the technology demonstration is i). Accelerating production of fodder through promotion of fodder production, conservation and utilization enhancing the availability of the fodder throughout the year ii). Developing seed and planting material demonstrations units at KVK for fulfill the requirements of their vicinity. iii). Establishing back ward and forward linkages with different stake holders for profitable forage based life style husbandry

    Probing the Z = 6 spin-orbit shell gap with (p,2p) quasi-free scattering reactions

    The evolution of the traditional nuclear magic numbers away from the valley of stability is an active field of research. Experimental efforts focus on providing key spectroscopic information that will shed light into the structure of exotic nuclei and understanding the driving mechanism behind the shell evolution. In this work, we investigate the Z=6 spin-orbit shell gap towards the neutron dripline. To do so, we employed NA(p,2p)CA−1 quasi-free scattering reactions to measure the proton component of the 21+ state of 16,18,20C. The experimental findings support the notion of a moderate reduction of the proton 1p1/2−1p3/2 spin-orbit splitting, at variance to recent claims for a prevalent Z=6 magic number towards the neutron dripline.</p

    Determinants and prognostic implications of Cardiac Troponin T measured by a sensitive assay in Type 2 Diabetes Mellitus

    <p>Abstract</p> <p>Background</p> <p>The cardiac troponins are biomarkers used for diagnosis of myocardial injury. They are also powerful prognostic markers in many diseases and settings. Recently introduced high-sensitivity assays indicate that chronic cardiac troponin elevations are common in response to cardiovascular (CV) morbidity. Type 2 diabetes mellitus (T2DM) confers a high risk of CV disease, but little is known about chronic cardiac troponin elevations in diabetic subjects. Accordingly, we aimed to understand the prevalence, determinants, and prognostic implications of cardiac troponin T (cTnT) elevations measured with a high-sensitivity assay in patients with T2DM.</p> <p>Methods</p> <p>cTnT was measured in stored, frozen serum samples from 124 subjects enrolled in the Asker and Bærum Cardiovascular Diabetes trial at baseline and at 2-year follow-up, if availabe (96 samples available). Results were analyzed in relation to baseline variables, hospitalizations, and group assignment (multifactorial intensive versus conventional diabetes care for lowering CV risk).</p> <p>Results</p> <p>One-hundred thirteen (90 %) had detectable cTnT at baseline and of those, 22 (18 % of the total population) subjects had values above the 99th percentile for healthy controls (13.5 ng/L). Levels at baseline were associated with conventional CV risk factors (age, renal function, gender). There was a strong correlation between cTnT levels at the two time-points (r = 0.92, p > 0.001). Risk for hospitalizations during follow-up increased step-wise by quartiles of hscTnT measured at baseline (p = 0.058).</p> <p>Conclusions</p> <p>Elevations of cTnT above the 99th percentile measured by a highly sensitive assay were encountered frequently in a population of T2DM patients. cTnT levels appeared to be stable over time and associated with conventional CV risk factors. Although a clear trend was present, no statistically robust associations with adverse outcomes could be found.</p

    Dynamic tuning of plasmon resonance in the visible using graphene

    Get PDF
    We report active electrical tuning of plasmon resonance of silver nanoprisms (Ag NPs) in the visible spectrum. Ag NPs are placed in close proximity to graphene which leads to additional tunable loss for the plasmon resonance. The ionic gating of graphene modifies its Fermi level from 0.2 to 1 eV, which then affects the absorption of graphene due to Pauli blocking. Plasmon resonance frequency and linewidth of Ag NPs can be reversibly shifted by 20 and 35 meV, respectively. The coupled graphene-Ag NPs system can be classically described by a damped harmonic oscillator model. Atomic layer deposition allows for controlling the graphene-Ag NP separation with atomic-level precision to optimize coupling between them. © 2016 Optical Society of America

    Wholegrain fermentation affects gut microbiota composition, phenolic acid metabolism and pancreatic beta cell function in a rodent model of type 2 diabetes

    The intestinal microbiota plays an important role in host metabolism via production of dietary metabolites. Microbiota imbalances are linked to type 2 diabetes (T2D), but dietary modification of the microbiota may promote glycemic control. Using a rodent model of T2D and an in vitro gut model system, this study investigated whether differences in gut microbiota between control mice and mice fed a high-fat, high-fructose (HFHFr) diet influenced the production of phenolic acid metabolites following fermentation of wholegrain (WW) and control wheat (CW). In addition, the study assessed whether changes in metabolite profiles affected pancreatic beta cell function. Fecal samples from control or HFHFr-fed mice were fermented in vitro with 0.1% (w/v) WW or CW for 0, 6, and 24 h. Microbiota composition was determined by bacterial 16S rRNA sequencing and phenolic acid (PA) profiles by UPLC-MS/MS. Cell viability, apoptosis and insulin release from pancreatic MIN6 beta cells and primary mouse islets were assessed in response to fermentation supernatants and selected PAs. HFHFr mice exhibited an overall dysbiotic microbiota with an increase in abundance of proteobacterial taxa (particularly Oxalobacteraceae) and Lachnospiraceae, and a decrease in Lactobacillus. A trend toward restoration of diversity and compositional reorganization was observed following WW fermentation at 6 h, although after 24 h, the HFHFr microbiota was monodominated by Cupriavidus. In parallel, the PA profile was significantly altered in the HFHFr group compared to controls with decreased levels of 3-OH-benzoic acid, 4-OH-benzoic acid, isoferulic acid and ferulic acid at 6 h of WW fermentation. In pancreatic beta cells, exposure to pre-fermentation supernatants led to inhibition of insulin release, which was reversed over fermentation time. We conclude that HFHFr mice as a model of T2D are characterized by a dysbiotic microbiota, which is modulated by the in vitro fermentation of WW. The differences in microbiota composition have implications for PA profile dynamics and for the secretory capacity of pancreatic beta cells

    Determination and expression of genes for resistance to blast (Magnaporthe oryza) in Basmati and non-Basmati indica rices (Oryza sativa L.)

    One hundred and twenty two (122) genotypes of Basmati and non-Basmati Indica rice genotypes were evaluated for expression of resistance against blast disease under induced epiphytotic conditions. Disease severity (%) and area under disease progress curve (AUDPC) parameters were used for screening the blast resistance. Only 13 genotypes expressed resistance against the blast disease. Nine genotypes carried blast resistance genes but, were susceptible under induced epiphytotic conditions. The rice genotype VLD-61 had no resistance genes; however, it expressed strong resistance against blast. An empirical breeding strategy for development of blast resistant improved varieties of rice was also discussed.Keywords: Magnaporthe oryzae, restriction digestion, molecular breeding, Basmati riceAfrican Journal of Biotechnology Vol. 12(26), pp. 4098-410
