Evaluation of fungicides for the management of pearl millet [ Pennisetum glaucum (L.)] blast caused by Magnaporthe grisea

Blast disease caused by Magnaporthe grisea has emerged as a serious threat to pearl millet cultivation in India. Most of the hybrids being grown in India are susceptible to blast as not much efforts have been made to breed for blast resistance in pearl millet. In the absence of host plant resistance, the disease can be effectively managed with chemical fungicides. Therefore, nine fungicides, chlorothalonil, tricyclazole, hexaconazole, kasugamycin, benomyl, carbendazim, tebuconazole + trifloxystrobin, propiconazole and metalaxyl + mancozeb were tested for their efficacy to manage blast disease on a blast susceptible pearl millet line ICMB 95444. Different combinations of seed treatment and foliar sprays were tested: seed treatment alone, seed treatment + one spray, seed treatment + two sprays, seed treatment + three sprays. None of the fungicides was found effective when used as seed treatment. Results of this study clearly demonstrated that the disease can be effectively managed with three sprays of tebuconazole + trifloxystrobin (Nativo) or propiconazole (Tilt)

Il10 Deficiency Rebalances Innate Immunity to Mitigate Alzheimer-Like Pathology

SummaryThe impact of inflammation suppressor pathways on Alzheimer’s disease (AD) evolution remains poorly understood. Human genetic evidence suggests involvement of the cardinal anti-inflammatory cytokine, interleukin-10 (IL10). We crossed the APP/PS1 mouse model of cerebral amyloidosis with a mouse deficient in Il10 (APP/PS1+Il10−/−). Quantitative in silico 3D modeling revealed activated Aβ phagocytic microglia in APP/PS1+Il10−/− mice that restricted cerebral amyloidosis. Genome-wide RNA sequencing of APP/PS1+Il10−/− brains showed selective modulation of innate immune genes that drive neuroinflammation. Il10 deficiency preserved synaptic integrity and mitigated cognitive disturbance in APP/PS1 mice. In vitro knockdown of microglial Il10-Stat3 signaling endorsed Aβ phagocytosis, while exogenous IL-10 had the converse effect. Il10 deficiency also partially overcame inhibition of microglial Aβ uptake by human Apolipoprotein E. Finally, the IL-10 signaling pathway was abnormally elevated in AD patient brains. Our results suggest that “rebalancing” innate immunity by blocking the IL-10 anti-inflammatory response may be therapeutically relevant for AD

USE OF RECYCLED PLASTIC AS REPLACEMENT OF FINE AGGREGATE IN STRUCTURAL CONCRETE

Now a days disposal of dissipate plastic is one of the major green problem all above the world. The objective of this review paper is to examine the usefulness of using waste plastic as fine aggregate substitute in concrete mixtures. The compressive and tensile strength of a variety of concrete specimens were tested to establish how the amalgamation of recycled plastic as a replacement of fine aggregate would affect the expansion of strength in the mixes. In this reading plastic waste was mixed with cement concrete in a variety of scope such as 0%-15% and the M20 grade test specimen were casted to learning the behavior of plastic mixed concrete. All stages of plastic replacement show a perceptible diminish in compressive strength and tensile strength. https://journalnx.com/journal-article/2015071

New Sources of Resistance to Multiple Pathotypes of Sclerospora graminicola in the Pearl Millet Mini Core Germplasm Collection

Downy mildew (DM), caused by Sclerospora graminicola (Sacc.) Schröt., is a highly destructive and widespread disease in most pearl millet [Pennisetum glaucum (L.) R. Br.] growing areas of Asia and Africa. Breeding for DM resistance continues to be an integral part of genetic improvement of pearl millet at ICRISAT, Patancheru, India. For the identification of new and diverse sources of DM resistance, a pearl millet mini core collection comprising 238 accessions was screened against eight pathotypes (Sg 384, Sg 409, Sg 445, Sg 457, Sg 510, Sg 519, Sg 526, and Sg 542) of S. graminicola collected from different geographical locations in India. Significant differences for DM reaction were observed among pathotypes, mini core accessions, and their interactions. Of the 238 accessions, 68 accessions were resistant (≤10% DM incidence) to pathotype Sg 510 followed by 40 accessions resistant to Sg 457. Resistance to pathotypes Sg 519, Sg 526, Sg 384, Sg 445, and Sg 542 was observed in 15, 27, 29, 30, and 34 mini core accessions, respectively. Resistance to two or more pathotypes was observed in 62 accessions. Several of these accessions also exhibited desirable agronomic traits. The multiple-pathotype-resistant germplasm accessions having desirable agronomic characteristics and collected from different agro-ecologies would be useful in breeding programs to develop pearl millet hybrids resistant to difficult-to-manage highly-virulent pathotypes of S. graminicola

The social geography of unmarried cohabitation in the USA, 2007-2011

US studies of marriage and cohabitation have mainly highlighted the social and racial differentials as they were observed in cross-sections, and have as a result essentially focused on the "pattern of disadvantage". The evolution of such social differentials over time and space reveals that this pattern of disadvantage has clearly persisted, but that it is far from covering the whole story. Historically, there has been a major contribution to the rise of cohabitation by white college students, and later on young white adults with higher education continued to start unions via cohabitation to ever increasing degrees. Only, they seem to move into marriage to a greater extent later on in life than other population segments. Also, the religious affiliation matters greatly: Mormons and evangelical Christians have resisted the current trends. Furthermore this effect is not only operating at the individual but at the contextual level as well. Conversely, even after controls for competing socio-economic explanations, residence in areas (either counties or PUMA-areas) with a Democratic voting pattern is related to higher cohabitation probabilities. And, finally, different legal contexts at the level of States also significantly contributed to the emergence of strong spatial contrasts. Hence, there is a concurrence of several factors shaping the present differentiations, and the rise of secular and liberal attitudes, i.e. the "ethics revolution", is equally a part of the explanation

IL-22 Signaling Contributes to West Nile Encephalitis Pathogenesis

The Th17 cytokine, IL-22, regulates host immune responses to extracellular pathogens. Whether IL-22 plays a role in viral infection, however, is poorly understood. We report here that Il22-/- mice were more resistant to lethal West Nile virus (WNV) encephalitis, but had similar viral loads in the periphery compared to wild type (WT) mice. Viral loads, leukocyte infiltrates, proinflammatory cytokines and apoptotic cells in the central nervous system (CNS) of Il22-/- mice were also strikingly reduced. Further examination showed that Cxcr2, a chemokine receptor that plays a non-redundant role in mediating neutrophil migration, was significantly reduced in Il22-/- compared to WT leukocytes. Expression of Cxcr2 ligands, cxcl1 and cxcl5, was lower in Il22-/- brains than wild type mice. Correspondingly, neutrophil migration from the blood into the brain was attenuated following lethal WNV infection of Il22-/- mice. Our results suggest that IL-22 signaling exacerbates lethal WNV encephalitis likely by promoting WNV neuroinvasion
