Background: Knowledge of the anatomy of the coronary venous system (CVS) is important for planning of cardiac interventions like cardiac resynchronization therapy or percutaneus mitral annuloplasty. Different methods have been used for preprocedural visualization of the CVS. However, limited data is available comparing invasive retrograde coronary sinus angiography (CSA) and non-invasive multi slice computed tomography (MSCT). Thus, a comparison of retrograde CSA and ECG-gated MSCT for the visualization of the CVS in patients with congestive heart failure (CHF) was performed.
Methods: 20 patients (male: 11) with CHF underwent CSA and MSCT (16 x 0.75 mm collimation, tube voltage: 120 kV, tube current: 550 mAs(eff)). Both methods were compared with respect to vessel diameter and visibility.
Results: Vessel visualization was better using retrograde CSA except for middle cardiac vein and small veins which were better seen with MSCT. Overall, there was a trend that MSCT detected more vessels. Vessel diameters were larger measured using retrograde CSA, but only statistically significant for the coronary sinus and middle cardiac vein.
Conclusion: Whereas MSCT is more suitable for an overview, retrograde CSA offers a more detailed visualization of the CVS including marginal and posterior veins than MSCT. Thus, retrograde CSA allows a better display of target vessels commonly used for cardiac interventions. Overall, these two imaging techniques offer complementary information.

The number of motor neurons (MNs) declines precipitously during the final trimester before birth. Thereafter, the number of MNs remains relatively stable, with their connections to skeletal muscle dependent on neurotrophins, including brain-derived neurotrophic factor (BDNF) signaling through its high-affinity full-length tropomyosin-related kinase receptor subtype B (TrkB.FL) receptor.

Article Synopsis
- Fluids in the body shift towards the head during spaceflight, causing internal jugular vein (IJV) swelling and changes in blood flow that may raise thrombosis risk.
- The study examined how brief weightlessness (0-G) impacts IJV size and blood flow, using ultrasound on 13 participants in different positions on Earth and during spaceflight.
- Findings showed that while both IJVs enlarge in 0-G, stagnant blood flow was observed in one participant's left IJV, suggesting potential negative effects on venous flow dynamics and increased thromboembolism risk for astronauts during space travel.
Preclinical safety evaluation of calcineurin inhibitors delivered through an intraductal route to prevent post-ERCP pancreatitis demonstrates endocrine and systemic safety.

Objective: There is an urgent need for safe and targeted interventions to mitigate post-ERCP pancreatitis (PEP). Calcineurin inhibitors (CnIs) offer therapeutic promise as calcineurin signaling within acinar cells is a key initiating event in PEP. In previous proof-of-concept studies using experimental models, we showed that concurrent intra-pancreatic ductal administration of the CnIs, tacrolimus (Tac) or cyclosporine A (CsA) with the ERCP radiocontrast agent (RC) prevented PEP.

Article Synopsis
- Endometrial tissue can flow backward into the peritoneal cavity during menstruation, leading to chronic inflammation in endometriosis if macrophages, which help clear this tissue, cannot move out properly.
- Research showed that M1 macrophages are significantly less mobile than M2 macrophages, making them more likely to accumulate in the peritoneum and contribute to a pro-inflammatory environment.
- A decrease in ceramide-1-phosphate (C1P), which normally aids macrophage migration, was linked to the M1 macrophages' poor movement, and inhibiting C1P production dramatically reduced the ability of both macrophage types to migrate.
