An effective synthetic approach has been demonstrated for the construction of diverse bicyclic fused cyclopentenones from Morita–Baylis–Hillman (MBH) carbonates of propiolaldehydes. The present transformation was initiated through the propargylation of an alkenylamine with an MBH carbonate followed by the Pauson–Khand reaction of the product methyl 3-(alkenylamino)-2-methylenealk-4-ynoate. This facile method provides diverse scaffolds of cyclopentenone fused with aza -cycles having additional functionality in good yields. [ABSTRACT FROM AUTHOR]

The article presents a case study of linear endoscopic ultrasound of splenic artery pseudoaneurysm of the abdomen in a 48-year-old man with episode of hematemesis and acute pancreatitis.

The article presents a case study of a 35-year-old patient presented with history of fatigue, loss of weight and appetite. The case mentions that patient was diagnosed with bilateral adrenal tuberculosis based on results of contrast-enhanced abdominal computed tomography, positron emission tomography and endoscopic ultrasound. The case also mentions that differential diagnosis of bilateral enlarged adrenal glands includes infections such as tuberculosis, histoplasmosis and neoplastic masses.

The article presents a case study of a 65-year-old man who suffered from bleeding from rectum. Topics discussed include ulcer in posterior rectal mucosa of the patient, thickening of submucosa and muscularis propria, the patient diagnosed with solitary rectal ulcer syndrome (SRUS) and the use of rectal ultrasonography in evaluating SRUS.

The article presents a case study of a 55-year-old male patient who was admitted to the hospital due to progressive dyspnea for four months.

The article presents a case study of a 30-year-old male patient who experienced idiopathic recurring acute pancreatitis for eight months. The topics discussed include the results of his abdominal ultrasonography showing the presence of bulky pancreas, the presence of ascaris worm found on his pancreas, and the estimated number of patients who suffered from pancreatic diseases due to the Ascaris lumbricoides infestation.
