Circular RNAs (Circ RNAs) are a group of endogenous non-coding RNAs (ncRNAs) which widespread in eukaryotic cells, and have been brought to the research hotspots recently. As a member of ncRNAs, Circ RNAs may play an important part in diseases by regulating target gene expressions, via epigenetic modifications. Colorectal Cancer (CRC) is a common malignant tumor worldwide, and its progress may be attributed to the dysfunctional expressions of target genes...
Spontaneous Coronary Artery Dissection (SCAD) is a disease caused by spontaneous tear of coronary artery intima or spontaneous bleeding in the vessel wall, which affects or blocks coronary artery blood flow. It is an important cause of non atherosclerotic acute coronary syndrome and acute myocardial infarction. In this case report the patient was treated with coronary angiography in the catheter room, temporary pacemaker implantation and intravascular ultrasound (IVUS).
The abdominal aorta is the main blood vessel in the abdominal cavity that transmits oxygenated blood from the thoracic cavity to the organs within the abdomen and to the lower limbs. Variations of the branches and bifurcation of the abdominal aorta with their relations with other abdominal and spinal structures are so important regarding abdominal and spinal surgery.
Surgery for a severely calcified sinus of Valsalva aneurysm can be challenging. We present a patient in whom a simplified approach did not suffice so that implantation of a composite graft was required combined with individual grafts to the coronary ostia instead of direct re-insertion into the prosthesis because of the high calcification load.
Primary neuroendocrine tumors of the breast are an uncommon and often overlooked subtype of breast carcinoma primarily affecting postmenopausal women. These rare tumors account for approximately 2-5% of all breast cancers and are classified as well-differentiated Neuroendocrine Tumors (NETs)
