Thiazide Diuretic Utilization Within the VA.

Background: The 2017 American College of Cardiology/American Heart Association blood pressure guideline recommends chlorthalidone as the preferred thiazide diuretic. We aimed to better understand thiazide prescribing patterns within the US Department of Veterans Affairs (VA).

Methods: A retrospective analysis was conducted of patients with a prescription for hydrochlorothiazide (HCTZ), chlorthalidone, indapamide, or any combination products containing these from January 1, 2016, to January 21, 2022.

Microevolutionary dynamics of eccDNA in Chinese hamster ovary cells grown in fed-batch cultures under control and lactate-stressed conditions.

Chinese hamster ovary (CHO) cell lines are widely used to manufacture biopharmaceuticals. However, CHO cells are not an optimal expression host due to the intrinsic plasticity of the CHO genome. Genome plasticity can lead to chromosomal rearrangements, transgene exclusion, and phenotypic drift.
