Hyperosmolarity-induced suppression of group B1 Raf-like protein kinases modulates drought-growth trade-off in .

When plants are exposed to drought stress, there is a trade-off between plant growth and stress responses. Here, we identified a signaling mechanism for the initial steps of the drought-growth trade-off. Phosphoproteomic profiling revealed that Raf13, a B1 subgroup Raf-like kinase, is dephosphorylated under drought conditions.

Introduction: Diazoxide is the first-line treatment for children with hyperinsulinemic hypoglycemia (HI). In these cases, diazoxide raises blood glucose levels by suppressing insulin release, preventing hypoglycemia, and potentially devastating end-organ sequelae. Hyperosmolar hyperglycemic state (HHS) is an exceedingly rare side effect of diazoxide.

Capivasertib is a new targeted therapy for the treatment of select cases of hormone receptor positive, HER2 negative advanced breast cancer. Hyperglycemia is a known adverse effect of capivasertib with a 16 % incidence rate, however life-threatening hyperglycemia occurs rarely (incidence 0.3 %).

Dry eye disease (DED) is a common multifactorial disorder characterized by a deficiency in the quality and/or quantity of tear fluid. Tear hyperosmolarity, the dysfunction of ion channel proteins, and eye inflammation are primarily responsible for the development and progression of DED. Alterations in the structure and/or function of ion channel receptors (transient receptor potential ankyrin 1 (TRPA1), transient receptor potential melastatin 8 (TRPM8), transient receptor potential vanilloid 1 and 4 (TRPV1 and TRPV4)), and consequent hyperosmolarity of the tears represent the initial step in the development and progression of DED.

Introduction: Brain metastases are difficult to treat due to the blood-brain barrier limiting the delivery of therapeutic agents to the brain effectively. Intraventricular drug delivery has not been well studied for intra-axial pathologies. However, our prior work demonstrated that intraventricular drug delivery in a hyperosmolar vehicle showed preferential accumulation of drug within breast cancer tissue compared to surrounding brain parenchyma.
