Understanding stoichiometric adjustments in a freshwater plant: Responses to sediment and water nutrient dynamics across lake trophic gradients

open access: yesLimnology and Oceanography, EarlyView.
Abstract Despite ongoing efforts to reduce nutrient inputs, eutrophication continues to disrupt biogeochemical cycles and destabilize freshwater food webs. In this study, we examine the stoichiometric responses of the freshwater plant Myriophyllum spicatum under varied environmental conditions across lakes of differing trophic status.

A low oxygen threshold for physiological responses and trace metal quotas of Prochlorococcus and Synechococcus

open access: yesLimnology and Oceanography, EarlyView.
Abstract Continued human activity is expected to accelerate ocean deoxygenation, leading to the expansion and shallowing of oxygen‐deficient zones (ODZs). This decline in oxygen may impact both phytoplankton growth and trace metal uptake. We conducted culture experiments with Prochlorococcus MIT9313 and Synechococcus XM‐24, two numerically dominant ...

Stereospecificity of the products of the fatty acid oxygenases derived from psoriatic scales.

open access: yesJournal of Lipid Research, 1991
The principal in vivo oxygenase products of arachidonic acid and linoleic acid in psoriatic skin scales are 12-hydroxyeicosatetraenoic acid (R/S ratio = 5.7), 13-hydroxyoctadecadienoic acid (S/R = 1.9), and 9-hydroxyoctadecadienoic acid (R/S = 2.4 ...

Cell Apoptosis and Glucocorticoid‐Induced Osteonecrosis

open access: yesMed Research, EarlyView.
The review identifies glucocorticoid‐induced osteocyte/osteoblast apoptosis as central to femoral head osteonecrosis (GION), mediated through STAT1‐caspase‐3, PI3K/Akt, Wnt/β‐catenin, and oxidative stress pathways. Emerging therapies targeting these pathways (e.g., HIF‐1α stabilization, AMPK activation, and exosome‐mediated miRNA delivery) show ...

Ks1, an epithelial cell-specific gene, responds to early signals of head formation in Hydra [PDF]

open access: yes, 1994
As a molecular marker for head specification in Hydra, we have cloned an epithelial cell-specific gene which responds to early signals of head formation.
