Comparison on hypoglycemic effect of Oyster (Pleurotusosteratus) and Reishi (Ganodermalucidum) mushroom in alloxan induced diabetic mice

Abstract: Pleurotusosteratus (family: Pleurotaceae) and Ganodermalucidum (family: ganodermataceae) are common edible mushrooms in Bangladesh. Ethyl acetate extract of Pleurotusosteratus and Ganodermalucidum were used to find out their hypoglycaemicactivity in alloxan induced diabetic mice. Ethyl acetate extract of Pleurotusosteratus and Ganodermalucidum reduced blood glucose level of 39.56% and 43.27% respectively at 24 hours after intrapertitoneal administration (P<0.005) inalloxan induced diabeticmice.The possible mechanism of hypoglycemic action is due to the increased glucose uptake in liver cells because it markedly lowers the blood glucose levels in alloxan induced diabeticmice.

Microbiome Dynamics of Bovine Mastitis Progression and Genomic Determinants

Abstract: The milk of lactating cows presents a complex ecosystem of interconnected microbial communities which can impose a significant influence on the pathophysiology of mastitis. Previously, we reported the alteration of microbiome (bacteria, archaea, virus) composition between clinical mastitis (CM) and healthy (H) milk. We hypothesized possible dynamic shifts of microbiome compositions with the progress of different pathological states of mastitis (CM, Recurrent CM; RCM, Subclinical Mastitis; SCM) determined by its favoring genomic potentials. To evaluate this hypothesis, we employed whole metagenome sequencing (WMS) in 20 milk samples (CM = 5, RCM = 6, SCM = 4, H = 5) to unravel the microbiome dynamics, interrelation, and relevant metabolic functions. PathoScope (PS) and MG-RAST (MR) analyses mapped the WMS data to 442 bacterial, 58 archaeal and 48 viral genomes with distinct variation in microbiome composition and abundances across these metagenomes (CM>H>RCM>SCM). PS analysis identified 385, 65, 80 and 144 bacterial strains in CM, RCM, SCM, and H milk, respectively, with an inclusion of 67.19% previously unreported opportunistic strains in mastitis metagenomes. Moreover, MR detected 56, 13, 9 and 46 archaeal, and 40, 24, 11 and 37 viral genera in CM, RCM, SCM and H-milk metagenomes, respectively. The CM-microbiomes had closest association with RCM-microbiomes followed by SCM, and H-microbiomes. Furthermore, we identified 333, 304, 183 and 50 virulence factors-associated genes (VFGs), and 48, 31, 11 and 6 antibiotic resistance genes (AGRs) in CM, RCM, SCM, and H-microbiomes, respectively, showing a significant correlation between the relative abundances of VFGs (p = 0.001), ARGs (p = 0.0001), and associated bacterial taxa. We also detected correlated variations in the presence and abundance of several metabolic functional genes related to bacterial colonization, proliferation, chemotaxis, motility and invasion, oxidative stress, virulence and pathogenicity, phage integration and excision, biofilm-formation, and quorum-sensing to be associated with different episodes of mastitis. Therefore, profiling the dynamics of microbiome in different states of mastitis, concurrent VFGs, ARGs, and genomic functional correlations will contribute to developing microbiome-based diagnostics and therapeutics for bovine mastitis, and carries significant implications on curtailing the economic fallout from this disease.

Assessment of Hydrocarbon Generation Potential of Permian Gondwana Coals, Bangladesh

Abstract: This paper represents the geochemical characteristics of Gondwana coals from the Barapukuria coal mine,Bangladesh in order to investigate the potential for hydrocarbon generation. A total number of twenty three coal sampleswere analyzed – Rock-Eval pyrolysis, CHNS elemental analyses, maceral analysis and vitrinite reflectance. The sampleswere collected from drill hole GDH-40 of the Barapukuria coal mine encountered within Gondwana succession ofPermian age. The TOC contents of the coal samples range between ~50 and 76 wt.% and the organic matter consistspredominantly of type III and type IV kerogen with respect to hydrocarbon generation. The GP, HI, PI and Tmaxvalues range between 7 and 35 mg HC/g rock, 20 and 62 mg HC/g TOC, 0.02 and 0.04, and 430 and 437 oC, respectively.The organic matter is mainly gas prone and thermally immature to early mature level. The potential coal bed methane(CBM) generation of the Barapukuria basin is estimated to be 11 Gm3. Thus, underground coal gasification (UCG)is helpful for better development of subsurface coals at the Barapukuria basin, Bangladesh.This paper represents the geochemical characteristics of Gondwana coals from the Barapukuria coal mine,Bangladesh in order to investigate the potential for hydrocarbon generation.
