Hydrogen/deuterium exchange mass spectrometry (HDX-MS) is a powerful technique to interrogate protein structure and dynamics. With the ability to study almost any protein without a size limit, including intrinsically disordered ones, HDX-MS has shown fast growing importance as a complement to structural elucidation techniques. Current experiments compare two or more related conditions (sequences, interaction partners, excipients, conformational states, etc.

Apelin, a (neuro) vasoactive peptide, plays a prominent role in controlling water balance and cardiovascular functions. Apelin and its receptor co-localize with vasopressin in magnocellular vasopressinergic neurons. Apelin receptors (Apelin-Rs) are also expressed in the collecting ducts of the kidney, where vasopressin type 2 receptors are also present.

Objectives: Echinacoside (ECH) is an anti-fibrotic phenylethanoid glycoside derived from the plant that protects against cardiac dysfunction by mitigating apoptosis, oxidative stress, and fibrosis. Nevertheless, ECH's precise function and mechanisms in addressing cardiac fibrosis are still not fully understood.
Materials And Methods: In our current investigation, we induced cardiac fibrosis in mice by administering Angiotensin II (Ang II) and subsequently assessed the effects of ECH treatment four weeks post-fibrosis induction.
Impact of angiotensin receptor neprilysin inhibitor on serum C-peptide levels in patients with type 2 diabetes.

Sacubitril/valsartan, an angiotensin receptor neprilysin inhibitor (ARNI), is becoming more common in the treatment of heart failure and hypertension. Neprilysin is highly expressed in the renal tubules, and reports have shown increases in urinary C-peptide reactivity (CPR) levels after administration of ARNI. However, the effect of ARNI on serum CPR levels, a critical marker of insulin secretion in diabetes, remains underexplored.

Materials And Methods: Data from a computerized diabetic care database were used to retrospectively compare esaxerenone users (Group A) with non-esaxerenone users (Group B). Propensity score weighting was applied to Group B.
