Objective: To investigate the detection rate and possible causes of acute coronary infarction (AMI) patients with roughly normal coronary arteriographic (CAG) findings.
Method: A retrospective analysis was conducted in 311 cases of AMI undergoing CAG examination.
Result: Of these 311 patients, 16 patients, whose age averaged 47.6 years, had roughly normal findings in CAG, including 9 below the age of 45 years, 10 with smoking history, and 5 with successful thrombolysis.
Conclusion: Patients with normal or roughly normal CAG finding might also have AMI likely induced by coronary artery thrombosis and spasm.

Background: A stemless plastic scintillation detector (SPSD) is composed of an organic plastic scintillator coupled to an organic photodiode. Previous research has shown that SPSDs are ideally suited to challenging dosimetry measurements such as output factors and profiles in small fields. Lacking from the current literature is a systematic effort to optimize the performance of the photodiode component of the detector.

Although there has been some recent interest in the proton conductivity (σ) of highly stable carboxyl metal-organic frameworks (MOFs) made of tetravalent metal ions, given their potential applications in fuel cells and electrochemical sensing, research on MOFs constructed by hafnium(IV) ions needs to be expanded significantly. Based on this, we used two common and easily prepared phenylpoly(carboxylic acid) ligands, 1,2,4-phenyltricarboxylic acid and 1,2,4,5-phenyltetracarboxylic acid, to react with hafnium tetrachloride, respectively, creating two porous hafnium(IV)-based MOFs, () and UiO-66-(COOH)-Hf (), with the same structure as UiO-66-Hf but with different numbers of free carboxylic groups. A series of stability assays revealed that the two MOFs had excellent structural rigidity, including thermal and water stability.

Distribution characteristics and analysis of fungal aerosol concentration and particle size in air-conditioned wards in Wuhan, China.

Article Synopsis
- Fungal contamination in hospital air can impact the health of staff, patients, and caregivers, with a study in Wuhan revealing that factors like temperature, humidity, and seasonal changes significantly influence fungal concentration rather than disease type or personnel density.
- The analysis showed that airborne fungal particle sizes are normally distributed, with the highest proportions found in specific size ranges, but the median diameter remained below 3.19 μm across different departments in both winter and summer.
- The findings suggest a need for improved filtration efficiency for specific fungal particle sizes and the use of appropriate antifungal treatments and hygiene practices in hospital air management.
Brain-wide cell-type-specific transcriptomic signatures of healthy ageing in mice.
Nature

Allen Institute for Brain Science, Seattle, WA, USA.
Article Synopsis
- Biological aging involves a gradual loss of homeostasis in molecular and cellular functions, particularly in the brain, which contains diverse cell types that differ in their aging resilience.
- This study offers an extensive single-cell RNA sequencing dataset of approximately 1.2 million transcriptomes from brain cells in young and aged mice, identifying 847 cell clusters and 14 age-biased clusters predominantly involving glial types.
- Key findings reveal specific gene expression changes with aging, including decreased neuronal function genes and increased immune-related genes, particularly in cells around the third ventricle of the hypothalamus, suggesting its critical role in the aging process of the mouse brain.
