Bioactives From Brown Algae: Antioxidant, Anti‐Inflammatory, Anticancer, and Antimicrobial Potential

open access: yesChemBioEng Reviews, EarlyView.
This review explores key bioactives in brown algae and their antioxidant, anti‐inflammatory, anticancer, and antimicrobial properties. Covering studies from 2014 to 2024, it highlights their relevance in pharmaceuticals, nutraceuticals, cosmetics, and foods, while addressing challenges and future directions to unlock their full potential.

Octopaminergic modulation of temporal frequency tuning of a fly visual motion-sensitive neuron depends on adaptation level

open access: yesFrontiers in Integrative Neuroscience, 2015
Several recent studies in invertebrates as well as vertebrates have demonstrated that neuronal response characteristics of sensory neurons can be profoundly affected by an animal's locomotor activity.

Steroid Receptors and Vertebrate Evolution [PDF]

open access: yesarXiv, 2019
Considering that life on earth evolved about 3.7 billion years ago, vertebrates are young, appearing in the fossil record during the Cambrian explosion about 542 to 515 million years ago. Results from sequence analyses of genomes from bacteria, yeast, plants, invertebrates and vertebrates indicate that receptors for adrenal steroids (aldosterone ...

Spiders as surrogate species in ecological monitoring, habitat classification and reserve selection : a thesis presented in partial fulfilment of the requirements for the degree of Masters of Science in Ecology at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2001
The use of invertebrates in the monitoring of terrestrial ecosystems was investigated using spiders as a focal group. In a review of previous literature, spiders were found to meet the majority of criteria required of suitable ecological indicators ...

Mammalian Tolerance to Amino Acid Heterochirality

open access: yesChemBioChem, Accepted Article.
Organisms use amino acids predominantly in l‐configuration. On the other hand, a series of studies show that a variety of d‐amino acids also occur in mammals and amino acid homochirality is not complete. Mammals de novo synthesize most amino acids with l‐configuration, but serine and aspartate are converted from l‐ to d‐configuration by endogenous ...

Interferon functional analog activates antiviral Jak/Stat signaling through integrin in an arthropod

open access: yesCell Reports, 2021
Summary: Drosophila Vago is a small antiviral peptide. Its ortholog in Culex mosquito was found to be an interferon-like cytokine that limits virus replication through activating Jak/Stat signaling.

A Faunal Analysis of the Springs of the Ouachita Mountains, Arkansas [PDF]

open access: yes, 1981
Spring ecosystems in Arkansas have historically received little attention. A faunal survey was made of 33 springs located in the core area Ouachita Mountains physiographic province. The study area was 135 x 80 km extending west from Hot Springs, Arkansas

Lacustrine and fan‐delta sediments in syn‐rift lake basins

open access: yesThe Depositional Record, EarlyView.
A consistent model for the sequence framework and depositional pattern of asymmetric half‐grabens in syn‐rift lake basins bounded by active faults has been established, complementing existing models for marine rift successions. Syn‐rift lake basins are characterised by relatively small dimensions, steep slopes, poorly developed shoreline strata ...

Balancing between predation risk and food by boreal breeding ducks

open access: yesEcology and Evolution
Wetlands belong to the globally most threatened habitats, and organisms depending on them are of conservation concern. Wetland destruction and quality loss may affect negatively also boreal breeding ducks in which habitat selection often needs balancing ...
