ABSTRACT The agitation power input substantially impacts the oxygen transfer rate in aerobic fermentation processes. Furthermore, in a carbon‐limited process where the substrate feed rate is controlled by the concentration of dissolved oxygen, the power input will consequently govern the feed rate.

Legionella RavZ Plays a Role in Preventing Ubiquitin Recruitment to Bacteria-Containing Vacuoles
Bacterial pathogens like Salmonella and Legionella establish intracellular niches in host cells known as bacteria-containing vacuoles. In these vacuoles, bacteria can survive and replicate.

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Cell vacuolation induced by Haemophilus influenzae supernatants in HEp-2 cells
Haemophilus influenzae belongs to respiratory tract microbiota. We observed vacuoles formation in previous studies with H. influenzae culture supernatants, so in this work we characterised that cytotoxic effect.

ABSTRACT Engineered nanomaterials (ENMs) are increasingly applied in agriculture to improve crop yield, nutrient efficiency, and food quality. This study examines the environmental transformation of ENMs, their uptake in plants, and their transfer across the agri‐food chain leading to human exposure.

LOSS OF DIFFERENTIATING NEMATOCYTES INDUCED BY REGENERATION AND WOUND HEALING IN HYDRA [PDF]
Cell death was observed in the nematocyte differentiation pathway in Hydra during head and foot regeneration. This death occurs throughout the regenerating piece, is transient in nature and is selective for committed stenotele and desmoneme precursors ...

Design of Fuel‐Dependent, Complex‐Coacervate‐Based Synthetic Cells
Fuel‐dependent synthetic cells form and persist only in the presence of chemical fuel, decaying under starvation. We establish design rules for hexapeptide‐based coacervates, showing that tryptophan enhances polyanion binding, extends lifetime, and reduces waste sensitivity.

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case
Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...

ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

ABSTRACT The homeostatic cortical actin array in plant cells plays important roles in fundamental processes, including intracellular transport, secretion, cell expansion, and cytoplasmic streaming. In response to diverse chemical and mechanical signals, the cortical array can remodel within minutes to assume new configurations or altered filament ...
