Nutritional Requirements to Improve Delta-Endotoxins Production of Bacillus thuringiensis var. kurstaki Using Mixed Designs Modelling
(
Springer India
, 2017 , Article)
Bacillus thuringiensiskurstaki is a soil bacterium that produces insecticidal toxins called delta-endotoxins. In order to increase the toxic crystal concentrations in a low-cost culture medium and thus improve the biopesticide ...
Assessment of food safety knowledge, self-reported practices, and microbiological hand hygiene levels of produce handlers in Qatar
(
International Association for Food Protection
, 2019 , Article)
Food handling across the custody chain from production to consumption is one of the most important stages in which microbes can enter food from infected food handlers or due to cross-contamination. The wholesale produce ...
Background invertebrate herbivory on dwarf birch (Betula glandulosa-nana complex) increases with temperature and precipitation across the tundra biome
(
Springer Verlag
, 2017 , Article)
Chronic, low intensity herbivory by invertebrates, termed background herbivory, has been understudied in tundra, yet its impacts are likely to increase in a warmer Arctic. The magnitude of these changes is however hard to ...
Plant functional trait change across a warming tundra biome
(
Nature Publishing Group
, 2018 , Article)
The tundra is warming more rapidly than any other biome on Earth, and the potential ramifications are far-reaching because of global feedback effects between vegetation and climate. A better understanding of how environmental ...
Adsorptive Removal of Arsenic and Mercury from Aqueous Solutions by Eucalyptus Leaves
(
Springer International Publishing
, 2017 , Article)
The study is a first-time investigation into the use of Eucalyptus leaves as a low-cost herbal adsorbent for the removal of arsenic (As) and mercury (Hg) from aqueous solutions. The adsorption capacity and efficiency were ...
Global change effects on plant communities are magnified by time and the number of global change factors imposed
(
National Academy of Sciences
, 2019 , Article)
Global change drivers (GCDs) are expected to alter community structure and consequently, the services that ecosystems provide. Yet, few experimental investigations have examined effects of GCDs on plant community structure ...
Post K-Pg diversification of the mammalian order Eulipotyphla as suggested by phylogenomic analyses of ultra-conserved elements
(
Academic Press Inc.
, 2019 , Article)
The origin of the mammalian order Eulipotyphla has been debated intensively with arguments around whether they began diversifying before or after the Cretaceous-Palaeogene (K-Pg) boundary at 66 Ma. Here, we used an in-solution ...
PRMT5-PTEN molecular pathway regulates senescence and self-renewal of primary glioblastoma neurosphere cells
(
Nature Publishing Group
, 2017 , Article)
Glioblastoma (GBM) represents the most common and aggressive histologic subtype among malignant astrocytoma and is associated with poor outcomes because of heterogeneous tumour cell population including mature non-stem-like ...
Flavin Oxidase-Induced ROS Generation Modulates PKC Biphasic Effect of Resveratrol on Endothelial Cell Survival.
(
MDPI
, 2019 , Article)
Dietary intake of natural antioxidants is thought to impart protection against oxidative-associated cardiovascular diseases. Despite many in vivo studies and clinical trials, this issue has not been conclusively resolved. ...
Short-term herbivory has long-term consequences in warmed and ambient high Arctic tundra
(
Institute of Physics Publishing
, 2017 , Article)
Climate change is occurring across the world, with effects varying by ecosystem and region but already occurring quickly in high-latitude and high-altitude regions. Biotic interactions are important in determining ecosystem ...
