Electrocommunication for weakly electric fish [PDF]

open access: yes, 2019
This paper addresses the problem of the electro-communication for weakly electric fish. In particular we aim at sheding light on how the fish circumvent the jamming issue for both electro-communication and active electro-sensing. A real-time tracking algorithm is presented.

Cytoplasmic delivery of antibodies through grafting a functional single complementarity‐determining region loop

open access: yesFEBS Letters, EarlyView.
We achieved cytoplasmic delivery of non‐cell‐penetrating IgGs by grafting a single functional complementarity‐determining region 1 (CDR1) from the light chain variable region (VL) of the cell‐internalizable 3D8 antibody. The engineered IgG acquired cell‐penetrating ability while maintaining antigen affinity, highlighting CDR1 grafting as a promising ...

Biochemical Composition of Indigenous and Imported Trout and Salmon

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
As wild fish are a finite resource, the role of aquaculture in providing the necessary fish per capita is becoming increasingly important. Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) are species of interest to Romanians, rich ...

Protonophore activity of short‐chain fatty acids induces their intracellular accumulation and acidification

open access: yesFEBS Letters, EarlyView.
The protonated form of butyrate, as well as other short‐chain fatty acids (SCFAs), is membrane permeable. In acidic extracellular environments, this can lead to intracellular accumulation of SCFAs and cytosolic acidification. This phenomenon will be particularly relevant in acidic environments such as the large intestine or tumor microenvironments ...

E-educational Resource for Simulator Training of Marine Engineers and Bachelors in Engineering

open access: yesStudia Periegetica, 2016
Sustainable development of the Baltic Sea region cannot be imagined without the continuous improvement of the quality of higher education. Maritime and ecological education takes a special role in the development of this region. Shipping has always had a

Fish hemoglobins [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 2007
Vertebrate hemoglobin, contained in erythrocytes, is a globular protein with a quaternary structure composed of 4 globin chains (2 alpha and 2 beta) and a prosthetic group named heme bound to each one. Having myoglobin as an ancestor, hemoglobin acquired the capacity to respond to chemical stimuli that modulate its function according to tissue ...

Unlocking the potential of tumor‐derived DNA in urine for cancer detection: methodological challenges and opportunities

open access: yesMolecular Oncology, EarlyView.
Urine is a rich source of biomarkers for cancer detection. Tumor‐derived material is released into the bloodstream and transported to the urine. Urine can easily be collected from individuals, allowing non‐invasive cancer detection. This review discusses the rationale behind urine‐based cancer detection and its potential for cancer diagnostics ...

Model-based versus model-free feeding control and water quality monitoring for fish growth tracking in aquaculture systems [PDF]

open access: yesarXiv, 2023
The high concentration level of the environmental factors, such as a high ammonia concentration and pH level, affect the water quality, affecting fish's survival and mass death. Therefore, there is a critical need to develop control strategies to determine optimal, efficient, and reliable feeding and water quality monitoring processes.

Use of Sucker-Fishes in Fishing [PDF]

open access: yesNature, 1889
WITH reference to Mr. Sclater's note in NATURE of January 24 (p. 295), on the use of the Remora in fishing, I would like to call attention to the use of sucker-fishes by the aboriginal inhabitants of Cuba. Ferdinand Columbus (“Churchill's Voyages,” 1704, vol. ii. p. 616) says these people used the sucker-fish to Catch both other fish and turtles. These
