Photosynthetic acclimation to high temperatures in wheat
( John Wiley & Sons, Ltd. , 1992 , Article)Growth and photosynthetic performance were assessed for the Finnish wheat Triticum aestivum L. var. APU under a cool (13/10�C day/night) and a warm (30/25�C day/night) regime. Plants exhibited a certain degree of acclimation ... -
Phylogeographic Patterns in Africa and High Resolution Delineation of Genetic Clades in the Lion (Panthera leo)
( Nature Publishing Group , 2016 , Article)Comparative phylogeography of African savannah mammals shows a congruent pattern in which populations in West/Central Africa are distinct from populations in East/Southern Africa. However, for the lion, all African populations ... -
Phylogeography of lions (Panthera leo ssp.) reveals three distinct taxa and a late Pleistocene reduction in genetic diversity
( Blackwell Publishing Ltd , 2009 , Article)Lions were the most widespread carnivores in the late Pleistocene, ranging from southern Africa to the southern USA, but little is known about the evolutionary relationships among these Pleistocene populations or the ... -
Physiochemical characterization and systematic investigation of metals extraction from fly and bottom ashes produced from municipal solid waste
( Public Library of Science , 2020 , Article)Incineration has emerged as one of the acceptable ways to treat municipal solid waste (MSW) due to its potential in reducing the mass and volume of the waste. However, it produces two major by-product residues, namely ... -
Phytochemical screening and assessment of pharmacological properties of Swertia chirayita (Roxb. ex fleming) root methanolic extract
( Asian Network for Scientific Information , 2017 , Article)Background and Objective: Various parts of medicinal plants have been used to treat specific disorder from ancient times. Swertia chirayita (Roxb. ex Fleming) is a customary folklore medicine, used in the treatment of liver ... -
Phytoplankton along the coastal shelf of an oligotrophic hypersaline environment in a semi-enclosed marginal sea: Qatar (Arabian Gulf)
( Elsevier , 2013 , Article)Phytoplankton biomass (chlorophyll a concentration), primary production, abundance, species diversity and species groupings were measured in the coastal waters surrounding Qatar (Arabian Gulf) at 13 stations in February ... -
Phytoremediation of heavy metals using Qatari flora
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Phytoremediation is a natural phenomenon utilizing plants species to reduce or remove organic and inorganic pollutants from contaminated soil, water and sediment sources. Several studies were conducted to demonstrate the ... -
Pilot-scale crossflow ultrafiltration of four different cell-sized marine microalgae to assess the ultrafiltration performance and energy requirements
( Elsevier , 2023 , Article)Four marine microalgae (e.g., Tetraselmis, Picochlorum, Dunaliella, and Synechococcus) with different cell sizes were harvested using pilot-scale ultrafiltration. Average permeate fluxes were 16.75, 19, 25.35, and 33.75 ... -
Planning for assisted colonization of plants in a warming world
( Nature Publishing Group , 2016 , Article)Assisted colonization is one way of facilitating range shifts for species that are restricted in their ability to move in response to climate change. Here we conceptualize and apply a new decision framework for modelling ... -
Plant Antimicrobial Peptides as Potential Tool for Topic Treatment of Hidradenitis Suppurativa
( Frontiers Media , 2021 , Article)Among chronic skin autoinflammatory diseases, Hidradenitis Suppurativa (HS) stands out for its chronicity, highly variable condition, and profound impact on the patients’ quality of life. HS is characterized by suppurative ... -
Plant defensins: types, mechanism of action and prospects of genetic engineering for enhanced disease resistance in plants
( Springer Verlag , 2019 , Article Review)Natural antimicrobial peptides have been shown as one of the important tools to combat certain pathogens and play important role as a part of innate immune system in plants and, also adaptive immunity in animals. Defensin ... -
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 ... -
Pleiotropic role of notch signaling in human skin diseases
( MDPI , 2020 , Article Review)Notch signaling orchestrates the regulation of cell proliferation, differentiation, migration and apoptosis of epidermal cells by strictly interacting with other cellular pathways. Any disruption of Notch signaling, either ... -
