You will be shown an abstract from a biomedical research paper. Given this abstract, your task is to extract all unique entities of the following types: ["HealthCareActivity", "InjuryOrPoisoning", "BodySubstance", "IntellectualProduct", "AnatomicalStructure", "SpatialConcept", "Chemical", "Bacterium", "MedicalDevice", "Organization", "BiomedicalOccupationOrDiscipline", "Finding", "BiologicFunction", "Virus", "ResearchActivity", "ClinicalAttribute", "PopulationGroup", "Eukaryote", "BodySystem", "Food", "ProfessionalOrOccupationalGroup"].

Please return the output as a JSON object of the format: {"Virus": ["HIV", ...], "Bacterium": ["MRSA", ...], "AnatomicalStructure": ["Lung", ...], "BodySystem": ["CNS", ...], "BodySubstance": ["Serum", ...], "Finding": ["Headache", ...], "InjuryOrPoisoning": ["Fracture", ...], "BiologicFunction": ["Death", ...], "HealthCareActivity": ["Biopsy", ...], "ResearchActivity": ["Clinical trial", ...], "MedicalDevice": ["Lenses", ...], "SpatialConcept": ["Camps", ...], "BiomedicalOccupationOrDiscipline": ["Forensic medicine", ...], "Organization": ["WHO", ...], "ProfessionalOrOccupationalGroup": ["Provider", ...], "PopulationGroup": ["Swimmers", ...], "Chemical": ["Gold", ...], "Food": ["Rice", ...], "IntellectualProduct": ["RPAM", ...], "ClinicalAttribute": ["Biomarker", ...], "Eukaryote": ["Dogs", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

The Physiological Role and Regulation of Aquaporins in Teleost Germ Cells The unicellular germ cells and gametes of oviparous teleosts lack the osmoregulatory organs present in juveniles and adults, yet during development and particularly at spawning, they face tremendous osmotic challenges when released into the external aquatic environment. Increasing evidence suggests that transmembrane water channels (aquaporins) evolved to play vital adaptive roles that mitigate the osmotic and oxidative stress problems of the developing oocytes, embryos and spermatozoa. In this chapter, we provide a short overview of the diversity of the aquaporin superfamily in teleosts, and summarize the findings that uncovered a highly specific molecular regulation of aquaporins during oogenesis and spermatogenesis. We further review the multiple functions that these channels play during the establishment of egg buoyancy and the activation and detoxification of spermatozoa in the marine environment.
