Objective: Evaluate the relationship of cathepsin-D (CD) on disease severity and clinical outcomes for women with peripartum cardiomyopathy.
Background: Cathepsin-D is a protease released during oxidative stress that cleaves prolactin (PRL) generating a 16 kDa fragment that is pro-apoptotic, anti-angiogenic, and has been implicated in the pathogenesis of peripartum cardiomyopathy (PPCM).
Methods: In 99 women with newly diagnosed PPCM enrolled in the Investigation in Pregnancy Associated Cardiomyopathy (IPAC) study, CD levels were assessed by ELISA from serum obtained at study entry.
Background: Black women with peripartum cardiomyopathy (PPCM) have a higher prevalence of hypertensive disorders of pregnancy (HDP) and worse clinical outcomes compared with non-Black women. We examined the impact of HDP on myocardial recovery in Black women with PPCM.
Methods: A total of 100 women were enrolled into the Investigation in Pregnancy Associated Cardiomyopathy (IPAC) study.
Gefapixant citrate is a P2X3 purinergic receptor antagonist developed for the treatment of chronic cough. Gefapixant freebase is the penultimate intermediate in the commercial manufacturing route for gefapixant citrate and contains a complex impurity profile consisting of acidic and basic analytes. A UHPLC method was developed for assay and purity determination of gefapixant freebase utilizing a Waters Acquity Charged Surface Hybrid (CSH) C18 column (2.

Previous studies have shown that stress-induced OsNAC5 from rice (Oryza sativa L.) is up-regulated by senescence and might be involved in control of iron (Fe) and zinc (Zn) concentrations in rice seeds.

- Type I collagen changes lead to osteogenesis imperfecta (OI), a disorder causing fragile bones and significant respiratory issues, especially in infants and adults.
- A large study on various mouse models of OI revealed consistent lung defects like simplified alveolar structure and reduced surface area, indicating a connection between lung and bone health.
- Respiratory function was more severely affected in male mice, highlighting the need for further research on how these findings apply to human OI patients and the interplay between lung and skeletal issues.
