The purpose of this study is to investigate the development of egg and larvae morphology in the Ungcheon-stream. eggs were round and ranged in size from 1.86-2.01 mm (mean 1.91±0.14 mm). Immediately after hatching, the larvae had egg yolk in the abdomen with a total length of 5.27-6.63 mm (mean 5.95±0.96 mm). On the 10 days after hatching, the latter was 8.44-8.65 mm (mean 8.54±0.14 mm) in total length, and 5 dorsal fin rays were formed in dorsal fin and 8 caudal fin soft rays were formed in caudal fin. At 88 days after hatching, total length was 26.2-25.7 mm (mean 25.9±0.35 mm), and scales were formed throughout the body. The fin rays of each part were iii.7 in dorsal fin and iii.6 in anal fin, and finally the external form was the same as the adult fish.

Osmoregulation affects elimination of microplastics in fish in freshwater and marine environments.

Sci Total Environ

January 2025

Graduate School of Frontier Sciences, The University of Tokyo, Kashiwa 277-8563, Chiba, Japan; Atmosphere and Ocean Research Institute, The University of Tokyo, Kashiwa 277-8564, Chiba, Japan.

In recent decades, microplastics (MPs) have emerged as one of the biggest environmental challenges in aquatic environments. Ingestion and toxicity of MPs in seawater (SW) and freshwater (FW) fish have been studied extensively both in field and laboratory settings. However, the basic mechanism of how fish deal with MPs in SW and FW remains unclear, although physiological conditions of fish differ significantly in the two environments.

In three studies (total N = 622), the effects of threat to control on subsequent moral judgement were examined. After recalling a lack-of-control experience, participants evaluated the morality of a protagonist's decisions in a series of incongruent moral dilemmas. We found that a control-threatening reminder made moral judgements more utilitarian on the deontological-utilitarian dimension, which is consistent with the control motivation theory.

Risk factors for delayed gastric emptying after pancreatoduodenectomy: a 10-year retrospective study.

Ann Med

December 2025

Department of Surgery, Faculty of Medicine, Unit of Hepato-Pancreato-Biliary Surgery and Abdominal Organ Transplantation, Doce de Octubre University Hospital, Instituto de Investigación (imas12), Complutense University, Madrid, Spain.

Background: Delayed gastric emptying (DGE) is a frequent complication of pancreatoduodenectomy (PD) and is associated with prolonged hospital stay, readmission, increased hospital costs and decreased quality of life. However, the pathophysiology of DGE remains unclear.

Methods: This is a retrospective study of patients who underwent PD for pancreatic or periampullary tumours.

Association of Mobile Stroke Unit Care and Spending, Utilization, and Death in New York City.

J Am Heart Assoc

January 2025

Department of Population Health Sciences Weill Cornell Medicine New York NY.

Background: Transport by mobile stroke units (MSUs), which provide access to computed tomography scanning and intravenous blood pressure medications and thrombolytics, reduces time to treatment and may improve short-term functional outcomes for patients with acute stroke. The longer-term clinical and financial impacts remain incompletely understood. The aim of the study was to determine whether MSU care is associated with better health, utilization, and spending outcomes for patients with suspected acute stroke.

Prognostic Value of Frailty in Patients With Takotsubo Cardiomyopathy.

Clin Cardiol

January 2025

Unidad de Revisiones Sistemáticas y Meta-análisis (URSIGET), Vicerrectorado de Investigación, Universidad San Ignacio de Loyola, Lima, Peru.

Background: There is scarce data on the prognostic value of frailty in patients with Takotsubo cardiomyopathy (TCM). This study aimed to assess the association between frailty and in-hospital outcomes in patients with TCM.

Methods: Adult admissions with TCM were included using the 2016-2019 National Inpatient Sample database.
