Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Spatial metrics in fire ecology: seeking consistency amidst complexity

open access: yesBiological Reviews, EarlyView.
ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

Scale‐up of a monoclonal antibody CHO fed‐batch production in stirred tank bioreactors: Effect of hydrodynamic conditions and feeding regimen

open access: yesBiotechnology Progress, EarlyView.
Abstract Key hydrodynamic‐related parameters such as volumetric power input (P/V), impeller configuration, aeration strategy, and maximum gas sparge rate, as well as an appropriate feeding strategy, must be carefully selected to improve production yields in bioreactor.

Dynamic pH profiles drive higher cell‐specific and volumetric productivity

open access: yesBiotechnology Progress, EarlyView.
Implementation of dyamic pH profiles for increased CHO cell culture productivity. Abstract Mammalian cell cultures in bioreactors rely heavily on critical process parameter control to ensure optimal growth, productivity, and reproducibility to produce recombinant therapeutic proteins. Culture pH has been shown to be a critical parameter that influences

Optimizing sterile filtration of nanoemulsions through proper choice of prefilter properties

open access: yesBiotechnology Progress, EarlyView.
Abstract Nanoemulsions, with droplet sizes between 20 and 200 nm, have emerged as a promising vaccine adjuvant and drug delivery system, enhancing the solubility of hydrophobic drugs for diverse applications. Sterile filtration of nanoemulsions is particularly challenging due to the similar size between the nanodroplets and the 0.2 μm nominal pore size

A comprehensive investigation of Glycoprotein-based nucleic acid vaccines for Hantaan Virus

open access: yesnpj Vaccines
Hemorrhagic fever with renal syndrome (HFRS) occurs throughout Eurasia with considerable morbidity and mortality. Currently, the absence of specific treatments or effective antiviral drugs for hantavirus infection makes developing safe and effective ...
