AI Article Synopsis
- The study aimed to identify angiography projections that result in a lower Dose Area Product (DAP) by analyzing DAP and fluoroscopy times during coronary angiography (CAG) and percutaneous coronary intervention (PCI) in 75 patients.
- Measurements showed that mean DAP was significantly higher in the PCI group compared to the CAG group, with specific projections identified as having the highest DAP rates.
- The findings suggest that certain angiographic projections expose patients to higher radiation levels, indicating a need to use less irradiating alternatives whenever possible.
Article Abstract
Introduction: We aimed to determine angiography projections with lower Dose Area Product (DAP) rate by measuring the mean DAP and fluoroscopy times in coronary angiography (CAG) and percutaneous coronary intervention (PCI) and calculating DAP rate in different projections.
Methods: DAP and fluoroscopy times were measured in all employed projections in real-time in 75 patients who underwent CAG or PCI by a single cardiologist in Madani Cardiovascular University Hospital (45 in CAG group and 30 in PCI group). DAP rate was calculated in both groups and in all projections. The projections with highest and lowest DAP rate were determined.
Results: Mean DAP was 436.73±315.85 dGy×cm(2) in CAG group and 643.26±359.58 dGy×cm(2) in PCI group. The projection 40° LAO/0° had the highest DAP rate in CAG group (28.98 dGy×cm(2)/ sec) and it was highest in 20° RAO/30° CR in PCI group (29.83 dGy×cm(2)/sec). The latter projection was also the most employed projection in PCI group.
Conclusion: The amount of radiation dose in this study is in consistent with the previous reports. Specific angiographic projections expose patients to significantly higher radiation and they should be avoided and replaced by less irradiating projections whenever possible.

Sugarcane is a major industrial crop highly susceptible to parasitic weed (Striga spp.), causing a 38% reduction in cane yield due to a longer lag phase of 20-40 days, and wider spacing. Herbicides with a longer retention and slow-release nature could allow Striga seeds to germinate and be killed before attaching to the host.

Objectives: To describe the workflow and value of three-dimensional rotational angiography (3DRA) in percutaneous pulmonary valve implantation (PPVI).
Background: 3DRA offers visualization of the entire topography in the chest and may enhance safety and reduce the risk for complications in PPVI through improved pre-procedural planning and per-procedural guidance.
Methods: All PPVI procedures with the use of 3DRA performed between August 2011 and December 2022 were reviewed.

Genetic testing plays a crucial role in guiding individualized medication, however, detecting fine structural mutations in genes continues to present significant challenges. This study introduces a dual-signal fluorescence system, termed FeO@Au@PEG@P1+MOF@P, that integrates magnetic separation of FeO@Au with NH-MIL-88 (MOF) catalysis. Initially, the specimen (T1/T2) facilitated the formation of a specific complex (FeO@Au@PEG@P1+T1/T2) with FeO@Au@PEG@P1.
