Background: Pulmonary hypertension (PH) often leads to right ventricle (RV) failure, a significant cause of morbidity and mortality. Despite advancements in PH management, progression to RV maladaptation and subsequent failure remain a clinical challenge. This study explored the effect of paroxetine, a selective serotonin reuptake inhibitor (SSRI), on RV function in a rat model of PH, hypothesizing that it improves RV function by inhibiting G protein-coupled receptor kinase 2 (GRK2) and altering myofilament protein phosphorylation.

Chronic pain is a prevalent condition affecting a significant portion of the global population and is known to be associated with an increased risk of cardiovascular diseases. Despite the clinical relevance, the mechanisms underlying the link between chronic pain and myocardial ischemia-reperfusion (MI/R) injury remain poorly understood. This study aimed to investigate the role of the superior cervical ganglion (SCG) in mediating the effects of chronic pain on MI/R injury and to develop a novel therapeutic strategy.

MicroRNAs (miRNAs) are short sequences of single-stranded non-coding RNAs that target messenger RNAs, leading to their repression or decay. Interestingly, miRNAs play a role in the cellular response to low oxygen levels, known as hypoxia, which is associated with reactive oxygen species and oxidative stress. However, the physiological implications of hypoxia-induced miRNAs ("hypoxamiRs") remain largely unclear.

The aim of this study was to investigate how ultraviolet B (UVB) light regulates AP-1 expression via the β2-adrenergic receptor (β2-AR) in epidermal keratinocytes, which in turn regulates melanin synthesis in melanocytes, thereby modulating downstream melanin production in skin hair follicles and altering mouse skin color. We established a UV-irradiated mouse model to investigate the effects of UV radiation on changes in skin color. By measuring changes in the expression of genes related to cutaneous sympathetic nerves, norepinephrine synthesis and melanin synthesis, we investigated the relationship between β2-AR expression and cutaneous melanogenesis and determined the localization of β2-AR in cells.

The current study aimed to propose a method to directly measure right cervical vagal nerve activity (cVNA) alongside renal sympathetic nerve activity (RSNA) in conscious rats. The right cervical vagus nerve was surgically exposed and fitted with a bipolar electrode to record cVNA. A microcatheter was used to administer levobupivacaine to selectively block afferent cVNA.
