Hyperledger Fabric (HLF) is an open-source platform for deploying enterprise-level permissioned blockchains where users from multiple organizations can participate. Preventing unauthorized access to resources in such blockchains is of critical importance. Towards addressing this requirement, HLF supports different access control models. However, support for Attribute-Based Access Control (ABAC) in the current version of HLF is not comprehensive enough to address various requirements that arise when multiple organizations interact in an enterprise setting. To address those shortcomings, in this paper, we develop and present methods for providing full ABAC functionality in Hyperledger Fabric. Performance evaluation under different network configurations using the Hyperledger Caliper benchmarking tool shows that the proposed approach is quite efficient in practice.

Primary esophageal melanoma (PEM) is a rare and aggressive malignancy with limited treatment options. Due to its rarity, no standardized guidelines exist for managing oligometastatic recurrence, particularly in resource-limited settings. We present a case of a 60-year-old male with PEM who underwent esophagectomy followed by surgical resection of an adrenal metastasis.

Background: Pediatric dentists employ both pharmacological and non-pharmacological behavior control methods. Despite the use of behavioral control techniques, some young children cannot undergo treatment in the office, making sedation or general anesthesia necessary. Premedication drugs can be used before general anesthesia to reduce anxiety, control pain, induce amnesia, prevent nausea, and avert potential complications.
