Oral cinacalcet administration decreases serum ionized calcium and parathyroid hormone concentrations in healthy dogs.

Cinacalcet is an oral calcimimetic that has potential to non-invasively treat primary hyperparathyroidism in dogs (Canis lupis familiaris). There is minimal data assessing its efficacy in dogs. This study aimed to determine whether a single dose of cinacalcet decreases serum ionized calcium (iCa), total calcium (tCa), and parathyroid hormone (PTH) concentrations.

Acute SGLT-2i treatment improves cardiac efficiency during myocardial ischemia independent of Na/H exchanger-1.

Aims: Sodium glucose co-transporter 2 inhibitors (SGLT2i) demonstrate cardioprotective benefits independent of a glucose lowering effect including preservation of cardiac function during a myocardial ischemia. Sodium‑hydrogen exchanger-1 (NHE-1), has been hypothesized to contribute to the cardiac effects of SGLT2i. We characterized the beneficial effects of acute pre-ischemia exposure to SGLT2i and explored the possibility that these effects are explained by NHE-1 inhibition.

Fatal melanoma with a novel MYO5A-BRAF fusion and small associated conventional nevus: A case report and review of literature.

Kinase fusions play an important role in the pathogenesis of Spitz neoplasms and occasionally non-Spitz neoplasms. We report a case of a 19-year-old woman with a growing nodule on the scalp, morphologically consistent with a diagnosis of melanoma with epithelioid features arising in association with small nevus. This tumor aggressively metastasized and failed to respond to immunotherapy.

Mineralocorticoid receptor blockade normalizes coronary resistance in obese swine independent of functional alterations in K channels.

Impaired coronary microvascular function (e.g., reduced dilation and coronary flow reserve) predicts cardiac mortality in obesity, yet underlying mechanisms and potential therapeutic strategies remain poorly understood.
