Extracellular vesicle-packaged mitochondrial disturbing miRNA exacerbates cardiac injury during acute myocardial infarction.

Mounting evidence suggests that extracellular vesicles (EVs) are effective communicators in biological signalling in cardiac physiology and pathology. However, the role of EVs in cardiac injury, particularly in ischemic myocardial scenarios, has not been fully elucidated. Here, we report that acute myocardial infarction (AMI)-induced EVs can impair cardiomyocyte survival and exacerbate cardiac injury.

Peripheral Serum Exosomes Isolated from Patients with Acute Myocardial Infarction Promote Endothelial Cell Angiogenesis via the miR-126-3p/TSC1/mTORC1/HIF-1α Pathway.

Purpose: Angiogenesis is required for improving myocardial function and is a key factor in long-term prognosis after an acute myocardial infarction (AMI). Although exosomes are known to play a crucial role in angiogenesis, the role of peripheral exosomes in angiogenic signal transduction in patients with AMI remains unclear. Here, we explored the effect of exosomes extracted from the peripheral serum of AMI patients on angiogenesis and elucidated the downstream pathways.

Experimental study on the control effect of different ventilation systems on fine particles in a simulated hospital ward.

In recent years, a large number of respiratory infectious diseases (especially COVID-19) have broken out worldwide. Respiratory infectious viruses may be released in the air, resulting in cross-infection between patients and medical workers. Indoor ventilation systems can be adjusted to affect fine particles containing viruses.

Maternal baseline characteristics, fetoplacental Doppler parameters, and conventional echocardiographic data were prospectively collected.

Polysaccharides in natural products that repair the damage to intestinal mucosa caused by cyclophosphamide and their mechanisms: A review.

Cyclophosphamide (CTX) is a commonly used antitumor drug in clinical practice, and intestinal mucosal injury is one of its main toxic side effects, which seriously affects the treatment tolerance and prognosis of patients. Therefore, the prevention of intestinal mucosal injury is a research hotspot. Studies have shown that polysaccharides can effectively prevent and improve CTX-induced intestinal mucosal injury and immune system disorders.

A primary benign cardiac tumor misdiagnosed as cardiac metastasis in the right atrium.

We present a patient with breast cancer with multiple metastases who had an unusual cardiac mass in the right atrium. The cardiac mass was initially diagnosed as malignant metastasis by transthoracic echocardiogram (TTE) but subsequently diagnosed as benign by contrast-enhanced ultrasonography, cardiac magnetic resonance imaging (MRI), and positron emission tomography/computed tomography (PET/CT). TTE is the preferred imaging method for examination of cardiac masses.

The diagnosis was established using transthoracic echocardiography and confirmed using cardiac magnetic resonance imaging.

Right coronary artery-right ventricular fistula complicated with infective endocarditis.

Coronary artery fistula (CAF) is a congenital disease in which a communication forms between one or more coronary arteries and a cardiac chamber or great vessel. We describe an infrequent case of right coronary artery (RCA) fistula into the right ventricle (RV) complicated by infective endocarditis in a child. The patient received echocardiography and contrast-enhanced multidetector computed tomography (MDCT).

miR-155 promotes fibroblast-like synoviocyte proliferation and inflammatory cytokine secretion in rheumatoid arthritis by targeting FOXO3a.

The present study aimed to explore the expression and effects of microRNA (miR)-155 in synovial fibroblasts of patients with rheumatoid arthritis (RA). A total of 89 synovial tissues from RA patients and 49 control synovial tissues were collected, and the levels of miR-155 were measured by reverse transcription quantitative-PCR and western blotting. Fibroblast-like synoviocytes (FLS) were isolated from synovial tissues from the control group and were used to evaluate the roles of miR-155 and forkhead box protein O3a (FOXO3a).

A silk fibroin based green nano-filter for air filtration.

Fibrous air filters fabricated by electrospinning have proved to be an effective approach among the various strategies for PM2.5 removal. However, in the electrospinning process, the large amounts of toxic organic solvents usually evaporate into the atmosphere and disposing of these used polymer-based air filters would leave further pollution in the environment.
