Persistent omphalomesenteric band is a rare cause of volvulus or intestinal obstruction. A 7-month-old male infant was brought to this Emergency Room after having shown poor appetite for three days, frequent bilious vomiting, and fever for half a day. Physical examination revealed the infant was dehydrated and had slight abdominal distension as well as hypoactive bowel sounds with a tender, ill-defined mass over right lower quadrant. Radiography and sonography were consistent with distal small bowel obstruction. Emergent laparotomy was done and a fibrous band found extending from the anti-mesenteric border of the ileum to the posterior wall of the umbilicus. Small bowel volvulus had occurred around the band and dilated small bowel was noted. An understanding of the embryologic development of these structures and their normal disappearance may assist pediatricians and surgeons to make the correct diagnosis and select the right pathoanatomic approach in surgery.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Archaeal RNA Polymerase

Archaeal RNA polymerases are most similar to eukaryotic RNA polymerase II but require the support of only two archaeal general transcription factors, TBP (TATA-box binding protein) and TFB (archaeal homologue of the eukaryotic general transcription factor TFIIB) to initiate basal transcription. Here is the latest research on archaeal RNA polymerases.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.
