AI and machine learning ethics, law, diversity, and global impact.

Artificial intelligence (AI) and its machine learning (ML) algorithms are offering new promise for personalized biomedicine and more cost-effective healthcare with impressive technical capability to mimic human cognitive capabilities. However, widespread application of this promising technology has been limited in the medical domain and expectations have been tampered by ethical challenges and concerns regarding patient privacy, legal responsibility, trustworthiness, and fairness. To balance technical innovation with ethical applications of AI/ML, developers must demonstrate the AI functions as intended and adopt strategies to minimize the risks for failure or bias.

Dynamics of GreB-RNA polymerase interaction allow a proofreading accessory protein to patrol for transcription complexes needing rescue.

The secondary channel (SC) of multisubunit RNA polymerases (RNAPs) allows access to the active site and is a nexus for the regulation of transcription. Multiple regulatory proteins bind in the SC and reprogram the catalytic activity of RNAP, but the dynamics of these factors' interactions with RNAP and how they function without cross-interference are unclear. In , GreB is an SC protein that promotes proofreading by transcript cleavage in elongation complexes backtracked by nucleotide misincorporation.

Pneumoretroperitoneum after Attempted Epidural Anesthesia.

Air may extend to the retroperitoneal space from retroperitoneal perforation of a hollow viscus, infection of the anterior pararenal space with gas-forming organisms and from pneumothorax or pneumomediastinum [1]. Rare pathologies, such as open reduction and internal fixation of femoral fractures and anaerobic abscess of the hip joint have also been described in relation to this complication [1,2]. A rare case of pneumoretroperitoneum caused by insufflation of air during an attempt to achieve epidural anesthesia is described.

Laparoscopic removal of local renal cell carcinoma recurrence.

Purpose: To describe an entirely laparoscopic technique for excising a recurrence of local renal cell carcinoma (RCC).

Materials And Methods: The patient is placed in a full flank position. A 10-mm trocar is inserted using Hasson's technique with three additional ports in the upper abdomen.
