Cardiovascular computed tomography angiography (CTA) is a widely used imaging modality in the diagnosis of cardiovascular disease. Advancements in CT imaging technology have further advanced its applications from high diagnostic value to minimising radiation exposure to patients. In addition to the standard application of assessing vascular lumen changes, CTA-derived applications including 3D printed personalised models, 3D visualisations such as virtual endoscopy, virtual reality, augmented reality and mixed reality, as well as CT-derived hemodynamic flow analysis and fractional flow reserve (FFRCT) greatly enhance the diagnostic performance of CTA in cardiovascular disease.

Background: Researchers have not studied the integrity, orderly correlation, and dynamic openness of complex organisms and explored the laws of systems from a global perspective. In the context of reductionism, antidepressant development formerly focused on advanced technology and molecular details, clear targets and mechanisms, but the clinical results were often unsatisfactory.

Purpose: MDD represents an aggregate of different and highly diverse disease subtypes.

The synthesis of cyclic carbonates through cycloaddition reactions between epoxides and carbon dioxide (CO) is an important industrial process. Metal-Organic Frameworks (MOFs) have functional and ordered pore structures, making them attractive catalysts for converting gas molecules into valuable products. One approach to enhance the catalytic activity of MOFs in CO cycloaddition reactions is to create open metal sites within MOFs.

The construction of efficient photocatalysts for water splitting to enable H evolution is pivotal to alleviate energy issues and environmental concerns. In this work, carbon dots (CDs) were prepared by employing "green solvent" ionic liquids as carbon sources and then combined with Pt/NH-MIL-125, resulting in the emergence of a high-efficiency photocatalyst termed CDs-Pt/NH-MIL-125 for the first time. This composite photocatalyst exhibited outstanding photocatalytic activity in H production under visible light irradiation.

Background: Poorly controlled type 2 diabetes mellitus (T2DM) is known to result in left ventricular (LV) dysfunction, myocardial fibrosis, and ischemic/nonischemic dilated cardiomyopathy (ICM/NIDCM). However, less is known about the prognostic value of T2DM on LV longitudinal function and late gadolinium enhancement (LGE) assessed with cardiac MRI in ICM/NIDCM patients.

Purpose: To measure LV longitudinal function and myocardial scar in ICM/NIDCM patients with T2DM and to determine their prognostic values.

ZnO/TiO catalysts with different ZnO contents have been prepared through equal volume impregnation method, characterized by XRD, SEM, Py-IR, ICP, XPS, NH-TPD and N adsorption/desorption, and evaluated in the synthesis of polycarbonate diol (PCDL) through transesterification. The results showed that titanium zinc oxide formed in these catalysts, and the content of acidic sites varied with the ZnO content, and ZnO/TiO (10%) has the highest acid amount. The ZnO/TiO (20%) with medium acidic sites showed the highest catalytic activity.

The mixed-ligand strategy is one of the important methods for preparing new materials and regulating the properties of materials. In this work, by introducing different auxiliary ligands (ALs), we have obtained a series of mixed-ligand uranyl complexes (-) from a flexible biphenyltetracarboxylic acid (Hbptc) with an adjustable orthogonal conformation and studied the influence of different organic base molecules on the coordination and assembly of Hbptc with a uranyl cation. It is found that the coordinated ALs, including 4,4'-bipyridine-1,1'-dioxide and 1,10-phenanthroline, partially occupy the coordination sites of the uranyl center and directly affect the molecular conformations and uranyl coordination of flexible bptc linkers.

Background: Key performance indices such as door-to-balloon times have long been recognized as quality metrics in reducing time to care for patients with acute coronary syndromes (ACS). In the situation where patients do not present to a facility capable of 24/7 percutaneous coronary interventions (PCI) delays in time to therapy can exceed the recommendation of 90 min or less. This study aimed to evaluate the impact of transfers on performance indices for patients diagnosed with ST-segment elevation myocardial infarction (STEMI).

Article Synopsis
  • Fly ash from burning trash is dangerous because it contains harmful metals and pollutants that can hurt the environment.
  • Researchers studied a special method called thermal plasma vitrification, which changes fly ash into a safer form, and compared it with other treatment methods.
  • They found that using plasma technology can greatly reduce environmental damage, especially when using clean energy, and it’s a better option for dealing with fly ash than other methods.

Coronary artery disease remains a major cause of mortality. Presence of atherosclerotic plaques in the coronary artery is responsible for lumen stenosis which is often used as an indicator for determining the severity of coronary artery disease. However, the degree of coronary lumen stenosis is not often related to compromising myocardial blood flow, as most of the cardiac events that are caused by atherosclerotic plaques are the result of vulnerable plaques which are prone to rupture.

  • The study investigates the effectiveness of 18F-FDG PET for assessing heart muscle viability in patients with coronary artery disease (CAD), comparing it to SPECT and echocardiography, with invasive coronary angiography as the reference.
  • Thirty patients with CAD participated, undergoing multiple imaging tests to evaluate diagnostic sensitivity and agreement between the different imaging methods.
  • Results showed that 18F-FDG PET had the highest sensitivity (100%) for detecting myocardial viability, suggesting it is a valuable diagnostic tool warranting further large-scale research.

Objectives: The coronary artery calcium (CAC) score has been shown to predict future cardiac events. However the extent to which the added value of a CAC score to the diagnostic performance of myocardial perfusion imaging (MPI) by single photon emission computed tomography (SPECT) is unclear. The purpose of this study is to investigate the correlation between CAC score and SPECT in patients with suspected coronary artery disease.

Abdominal aortic aneurysm is a common vascular disease that affects elderly population. Open surgical repair is regarded as the gold standard technique for treatment of abdominal aortic aneurysm, however, endovascular aneurysm repair has rapidly expanded since its first introduction in 1990s. As a less invasive technique, endovascular aneurysm repair has been confirmed to be an effective alternative to open surgical repair, especially in patients with co-morbid conditions.
