UJI TOKSISITAS BERBAGAI JENIS DAN KONSENTRASI DETERJEN TERHADAP TINGKAT KERUSAKAN INSANG DAN MORTALITAS IKAN MAS (Cyprinus carpio) [PDF]

open access: yes, 2010
Toxicity is toxic relative character related with its potential to cause negative effect for living creature. Water pollution is the entrance of living creature, element, energy, and another component in water by human activity so that the water quality ...

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Toxicity of Four Common Environmental Chemicals Across Caenorhabditis elegans Life Stages Supporting the One Health Concept

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Pesticides and pharmaceuticals are among the most common chemical groups in waterbodies and soils, and their universal distribution raises concerns about potential adverse effects on nontarget organisms and humans. Reproductive output disruption is of particular concern, as it transposes effects from the individual to the next generations at ...

Multistressor Interaction of Perfluorooctane Sulfonate (PFOS) and Temperature in Two Estuarine Fish Species, Red Drum (Sciaenops ocellatus) and Sheepshead Minnow (Cyprinodon variegatus)

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Perfluorooctane sulfonate (PFOS), a perfluoroalkyl substance (PFAS), is characterized by a long, fluorinated carbon chain which makes it ideal for oil‐ and water‐repellent products but detrimental for the environment, where it persists and accumulates in organisms.

Fish powder as a low-cost component in media for producing bacterial cellulose [PDF]

open access: yes, 2012
Some bacteria can produce extracellular bacterial cellulose (BC). This polysaccharide is chemically identical to cellulose produced by plants but has no associated lignin and hemicelluloses. The unique mechanical properties, chemical stability and purity

The valvula cerebelli of the spiny eel, Macrognathus aculeatus, receives primary lateral-line afferents from the rostrum of the upper jaw [PDF]

open access: yes, 1991
In the spiny eel, Macrognathus aculeatus, anterodorsal and (to a lesser degree) anteroventral lateralline nerves project massively to the granular layer of the valvula cerebelli, throughout its rostrocaudal extent.

Genome Expansion of ZPB1(a) and ZPC1(a) in Basal Species or Liver Expression of ZPB1a and ZPC1aa in Advanced Species, Two Different Strategies to Ensure Sufficient ZP Synthesis in Teleosts

open access: yesIntegrative Zoology, EarlyView.
We found that teleosts employed two different strategies to ensure sufficient ZP (zona pellucida) synthesis: expansion of ZPB1(a) and ZPC1(a) in basal species or liver expression of ZPB1a and ZPC1aa in advanced species. The N‐terminus of expanded ZPB1(a) or ZPC1(a) and liver‐expressed ZPB1a contains repeated units or low‐complexity regions to form ...

The Relationship of Ova Diameter to Fertilization Rates, Hatching Rates, Survival Percentages and Specific Growth Rates in the Common Carp and Indian Major Carps

open access: yesAsian Fisheries Science, 2007
The effects of different ova diameters on hatching, growth and survival of fry of the common carp (Cyprinus carpio var. communis, Cyprinidae) and Indian major carps viz.Catla catla, Labeo rohita, Cirrhinus mrigala (Cyprinidae) were examined.

High‐Altitude Adaptation of Frogs (Case Study: Nanorana parkeri): From Physiological Phenotypes to AltitudeOmics

open access: yesIntegrative Zoology, EarlyView.
High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.
