Lipoxygenases (LOX, linoleate: oxygen oxidoreductases, EC 1.13.11.12) constitute a family of dioxygenases, which contain non-heme, non-sulfide iron. These enzymes occur not only in animals, but in plants as well. They have been detected in coral, moss, fungi and also in some bacteria. LOXs catalyse the regiospecific and stereospecific insertion of molecular oxygen into the molecule of polyunsaturated fatty acid with the cis,cis- -1,4-pentadiene system to yield the corresponding hydroperoxides. This step of dioxygenation leads to a cascade of reactions called the lipoxygenase (octadecanoid) pathway. The products of this pathway (called oxylipins) play an important role as signal molecules in wound healing and defence processes in plants. In animals they are involved in inflammation, asthma and heart diseases.

Cholinesterase (ChE) inhibitors are under consideration to be used in the treatment of cardiovascular pathologies. A prerequisite to advancing ChE inhibitors into the clinic is their thorough characterization in the heart. The aim here was to provide a detailed analysis of cardiac ChE to understand their molecular composition, localization, and physiological functions.

Microbiome-animal host symbioses are ubiquitous in nature. Animal-associated microbiomes can play a crucial role in host physiology, health and resilience to environmental stressors. As climate change drives rising global temperatures and increases the frequency of thermal extremes, microbiomes are emerging as a new frontier in buffering vulnerable animals against temperature fluctuations.

Experiments have long been the gold standard for causal inference in Ecology. As Ecology tackles progressively larger problems, however, we are moving beyond the scales at which randomised controlled experiments are feasible. To answer causal questions at scale, we need to also use observational data -something Ecologists tend to view with great scepticism.

With many species interacting in nature, determining which interactions describe community dynamics is nontrivial. By applying a computational modeling approach to an extensive field survey, we assessed the importance of interactions from plants (both inter- and intra-specific), pollinators and insect herbivores on plant performance (i.e.

Purpose: Orvacabtagene autoleucel (orva-cel; JCARH125), a CAR T-cell therapy targeting B-cell maturation antigen (BCMA), was evaluated in relapsed/refractory multiple myeloma (RRMM) patients in the EVOLVE phase 1/2 study (NCT03430011). We applied a modified piecewise model to characterize orva-cel transgene kinetics and assessed the impact of various covariates on its pharmacokinetics (PK).
Experimental Design: The population PK analysis included 159 patients from the EVOLVE study.
