Anthraquinone derivatives are identified for their immune-boosting,anti-inflammatory,and anti-viral ***,the pre-sent study aimed to investigate the reported anthraquinone derivatives as immune booster molecules in COVID-19 infection and evaluate their binding affinity with three reported targets of novel coronavirus i.e.3C-like protease,papain-like protease,and spike *** reported anthraquinone derivatives were retrieved from an open-source database and filtered based on a positive druglikeness *** with positive druglikeness scores were predicted for their targets using DIGEP-Pred and the interaction among modulated proteins was evaluated using ***,the associated pathways were recorded concerning the Kyoto Encyclopedia of Genes and Genomes pathway ***,the docking was performed using autodock4 to identify the binding efficacy of anthraquinone derivatives with 3C-like protease,papain-like protease,and spike *** docking the pose of ligand scoring minimum binding energy was chosen to visualize the ligand-protein *** 101 bioactives,36 scored positive druglikeness score and regulated multiple pathways concerned with immune modulation and(non-)infectious ***,docking study revealed torososide B to possess the highest binding affinity with papain-like protease and 3C-like protease and 1,3,6-trihydroxy-2-methyl-9,10-anthraquinone-3-O-(6′-O-acetyl)-β-d-xylopyranosyl-(1→2)-β-d-glucopyranoside with spike protein.

Chinese Medicine 2011年第3期2卷 93-102页

作者： Parveen Kumar Sharma Surender Kumar Thakur S. Manuja R. K. Rana Pardeep Kumar Sanjay Sharma jagdish chand Ashok Singh Krishan Kumar Katoch 不详

The paper highlights the Phyto-diversity and indigenous uses an ecosystem existing in Lahaul Valley of tribal district of Lahaul and Spiti in Himacjhal Pradesh, India. This is one of the most preferred tourist spot especially for foreigners. The cold desert area of India is known for its specific topography, sense climate and unique vegetation. The valley is rich in high value medicinal wealth and local inhabitants (Buddhist) practice the Tebetan Amchi System of Medicine. Keeping in view the continuous pressure on nature, this paper reflects the Phyto-diversity of Valley, with reference to medicinal and aromatic plants and conserva-tion mechanisms to protect the valuable wealth of the valley and also suggests effective ecotourisim planning of the study area.

Hydropower if scientifically developed is considered to be one of the clean and non-polluted renewable energy *** its impacts always exist on physical and social environment of the *** present study was conducted in the River Satluj basin which is well known for its hydropower *** main objective of the study was to understand the vulnerability of the Satluj basin and to develop a strategy for the development of hydropower *** basin has been facing many problems relating to construction of haphazard development of hydropower *** has led multi-hazards like landslides,floods,earthquakes,***,vulnerability assessment index was assessed quantitatively and *** Information System and people’s perception were used to study these aspects in the *** parameters considered for vulnerability assessment were slope,slope profile,relative relief,curvature,slope aspect,soil texture,lithology,river morphometry,precipitation,hydroelectric projects,land use and land cover,mass-movement,flood,geological elements and earthquake *** highest vulnerability was found in the middle zone,and finally on the basis of parameters analyzed;the hydropower’s development strategy was developed.

Giant flares(GFs)are unusual bursts from soft gamma-ray repeaters(SGRs)that release an enormous amount of energy in a fraction of a *** afterglow emission of these SGR-GFs or GF candidates is a highly beneficial means of discerning their composition,relativistic speed and emission *** 200415A is a recent GF candidate observed in a direction coincident with the nearby Sculptor galaxy at 3.5 *** this work,we searched for transient gamma-ray emission in past observations by Fermi-LAT in the direction of GRB *** observations confirm that GRB 200415A is observed as a transient GeV source only once.A pure pair-plasma fireball cannot provide the required energy for the interpretation of GeV afterglow emission and a baryonic poor outflow is additionally needed to explain the afterglow emission.A baryonic rich outflow is also viable,as it can explain the variability and observed quasi-thermal spectrum of the prompt emission if dissipation is happening below the photosphere via internal *** the peak energy(Ep)of the time-resolved prompt emission spectra and their fluxes(Fp),we found a correlation between Ep and Fp or isotropic luminosity Liso for GRB *** supports the intrinsic nature of Ep-Liso correlation found in SGRs-GFs,hence favoring a baryonic poor *** results also indicate a different mechanism at work during the initial spike,and that the evolution of the prompt emission spectral properties in this outflow would be intrinsically due to the injection process.
