A new South American darter (Crenuchidae: Characidium) from rivers draining the Northeastern Mata Atlantica Freshwater Ecoregion, Brazil: morphological and molecular evidence

open access: yesJournal of Fish Biology, EarlyView.
Abstract Characidium tupi, a new species from rivers draining the southern portion of the Northeastern Mata Atlantica Freshwater Ecoregion, is described. The new species can be distinguished from all congeners by its colour pattern, including 7–14 dark bars enlarged and more conspicuous on their ventralmost portion, resulting in a longitudinal series ...

Atlantic salmon (Salmo salar L.) kelt rheotaxis and position choice are influenced by flow velocity and turbulence in a regulated river

open access: yesJournal of Fish Biology, EarlyView.
Abstract The migratory behaviour of Atlantic salmon kelts is poorly understood. Due to the Atlantic salmon's considerable socio‐economic and ecological importance, their precipitous population abundance declines, and the population resilience potential of salmon kelts, addressing these knowledge gaps is important.

Endoscopic Ultrasound for the Management of Pancreatic Neuroendocrine Tumors: Diagnosis, Treatment, and Future Perspectives

open access: yesJournal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Pancreatic neuroendocrine tumors (PanNETs) are increasingly diagnosed, reflecting greater clinical awareness, improved imaging, and revised classification. This review summarizes evidence on epidemiology, diagnostic workup, and endoscopic ultrasound (EUS)–guided management of PanNETs, encompassing diagnostic evaluation, tissue acquisition, and

Clinical Factors Associated With Endoscopic Decompression Failure and Recurrent Sigmoid Volvulus: A Retrospective Cohort Study

open access: yesJournal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Introduction Although sigmoid volvulus is a potentially life‐threatening condition in elderly patients, its prognostic factors are not well‐known. This study aimed to evaluate clinical outcomes and identify prognostic factors in patients with sigmoid volvulus.

Does Deposit Insurance Promote Deposit Stability? Evidence from the Postal Savings System during the 1920s

open access: yesJournal of Money, Credit and Banking, EarlyView.
Abstract We evaluate whether deposit insurance (DI) promotes liquidity by influencing depositor behavior. We use the postal savings (PS) system and state‐adopted DI schemes during the 1920s to examine the effect of bank suspensions on PS deposit growth in pairs of border cities (DI versus non‐DI).
