Background: Acute heart failure is a life-threatening clinical condition. Levosimendan is an effective inotropic agent used to maintain cardiac output, but its usage is limited by the lack of evidence in patients with severely abnormal renal function. Therefore, we analyzed data of patients with acute heart failure with and without abnormal renal function to examine the effects of levosimendan.

Regulation of a Cytochrome P450 Gene by WRKY33 Transcription Factor Controls Apoplastic Barrier Formation in Roots to Confer Salt Tolerance.

Salinity is an environmental stress that causes decline in crop yield. and other mangroves have adaptations such as ultrafiltration at the roots aided by apoplastic cell wall barriers to thrive in saline conditions. We studied a cytochrome P450 gene from , , and its putative ortholog in Arabidopsis (), , which are involved in apoplastic barrier formation.

Cathepsin S promotes the development of pulmonary arterial hypertension.

Cysteine cathepsin proteases play critical roles in cardiovascular disease progression and are implicated in extracellular matrix (ECM) degradation. Patients with pulmonary arterial hypertension (PAH) exhibit increased elastase production by pulmonary arterial smooth muscle cells (PASMCs), which is related to the degradation of elastic fibers and pulmonary vascular remodeling. However, the mechanism by which cathepsins regulate the ECM and PASMC proliferation in PAH remains unclear.

In recent years, several advancements in diagnosis and treatment of PAH has occurred.

Successful multidisciplinary treatment of uterine serous carcinoma in a patient who had previously undergone renal transplantation.

Objective: Renal transplantation is a risk factor for premalignant and malignant changes of the endometrium. Thus, prompt and aggressive treatment of postoperative complications remains a major issue. We report the case of an asymptomatic postmenopausal woman with a history of renal transplantation who underwent surgery for uterine serous carcinoma (USC).

Factors associated with undiagnosed obstructive sleep apnoea among hypertensive patients: A multisite cross-sectional survey study in Taiwan.

Aims And Objectives: To investigate the distribution and risk factors associated with undiagnosed obstructive sleep apnoea among hypertensive patients.

Background: Obstructive sleep Apnoea has been deemed a cardinal risk factor affecting cardiovascular event, and the condition is still frequently overlooked clinically. The lack of advanced diagnosis often causes hypertensive patients with obstructive sleep apnoea to miss opportunities for preventing chronic diseases.

Prostanoid EP agonist L-902,688 activates PPARγ and attenuates pulmonary arterial hypertension.

Prostacyclin agonists that bind the prostacyclin receptor (IP) to stimulate cAMP synthesis are effective vasodilators for the treatment of idiopathic pulmonary arterial hypertension (IPAH), but this signaling may occur through nuclear peroxisome proliferator-activated receptor-γ (PPARγ). There is evidence of scant IP and PPARγ expression but stable prostanoid EP receptor (EP) expression in IPAH patients. Both IP and EP functionally couple with stimulatory G protein (G), which activates signal transduction.
