Primary Cholangiocarcinoma of the Liver Presenting as a Complicated Hepatic Cyst: A Diagnostic Challenge.

Primary cholangiocarcinoma is a rare bile duct epithelial neoplasm that can present with atypical clinical manifestations, complicating its diagnosis. A 62-year-old male showed symptoms suggestive of a complicated hepatic cyst that was later identified as intrahepatic cholangiocarcinoma. The patient presented with abdominal discomfort without fever.

Miliary Tuberculosis Initially Presenting as an Isolated Hepatic Abscess.

Hepatic tuberculosis, typically associated with miliary tuberculosis, can occasionally present as localized liver lesions. This case report describes a 77-year-old male presenting with persistent abdominal pain and fever, following an endoscopic retrograde cholangiopancreatography for bile duct sludge removal. Subsequent computed tomography revealed focal liver lesions.

Revealing the synergistic impacts of ZIF-8 and copper co-exposure on zebrafish behavior, tissue damage, and intestine microbial community.

The application of metal-organic frameworks (MOFs) has garnered significant attention in contemporary research. However, the impacts of MOFs on aquatic environments remain largely unclear. This study revealed that the water stability of ZIF-8 is influenced by its concentration, with lower concentrations resulting in higher percentages of Zn release.

Investigating the design characteristics and parameter laws of bird-like flapping-wing aerial vehicles from the perspective of scaling.

Bird-like flapping-wing aerial vehicles (BFAVs) represent a significant advancement in the application of bird biology to aircraft design, with scaling analysis serving as an effective tool for identifying this design process. From the perspective of aviation designers, this paper systematically organizes the scaling laws of birds that are closely related to the design of BFAVs. An intriguing topic further explored is the comparison between birds and BFAVs from the standpoint of scaling, along with an examination of the differences in relevant design parameters.

Comparison of the efficacy of the modified internal brace and the arthroscopic Broström-Gould procedure for chronic lateral ankle instability.

Purpose: To compare the efficacy of an internal brace and the arthroscopic Broström-Gould procedure for chronic lateral ankle instability (CLAI).

Methods: The clinical data of 71 patients who were diagnosed with chronic lateral ankle instability between May 2020 and May 2022 were retrospectively analyzed. The American Orthopedic Foot and Ankle Society (AOFAS) scale, Foot and Ankle Ability Measure (FAAM), and Visual Analogue Scale (VAS) were used to assess clinical outcomes.
