New semi-crystalline photovoltaic polymers were synthesized and the optimized device exhibited 9.39% efficiency in a ∼300 nm thick single-cell device.
Abstract Background In this study, we investigated transcription and enzyme level responses of mussels Mytilus galloprovincialis exposed to hypoxic conditions. Genes for catalase (CAT), cytochrome P450, glutathione S -transferase (GST), metallothionein, superoxide dismutase (SOD), c oxidase subunit 1 (COX-1), NADH dehydrogenase 2 were selected study. Transcriptional changes in hypoxia 24 48 h compared control maintained at normal oxygen levels. Activities CAT, GST, SOD enzymes, lipid...
Unique among cnidarians, jellyfish have remarkable morphological and biochemical innovations that allow them to actively hunt in the water column were some of first animals become free-swimming. The class Scyphozoa, or true jellyfish, are characterized by a predominant medusa life-stage consisting bell venomous tentacles used for hunting defense, as well using pulsed jet propulsion mobility. Here, we present genome giant Nomura's (Nemopilema nomurai) understand genetic basis these key...
Coral reefs composed of stony corals are threatened by global marine environmental changes. However, soft coral communities octocorallian species, appear more resilient. The genomes several cnidarians species have been published, including from corals, sea anemones, and hydra. To fill the phylogenetic gap for octocoral cnidarians, we sequenced octocoral, Dendronephthya gigantea, a nonsymbiotic coral, commonly known as carnation coral. D. gigantea genome size is ∼276 Mb. A high-quality...
Gamma-aminobutyric acid (GABA)ergic neurons play a key role in pain modulation within the dorsal root ganglion (DRG), making them critical targets for therapeutic studies. This study utilized F11 cells as an vitro model to examine GABAergic function under high-glucose conditions mimicking diabetic neuropathy. Differentiated exhibited increased sensory neuronal marker expression and functional action potentials. Overexpression of transcription factor Achaete-scute homolog 1 (Ascl1) via...
During the course of a systematic screening peptide signaling molecules in Hydra novel peptide, Hym-355 (FPQSFLPRG-NH(2)), was identified. A cDNA encoding isolated and characterized. Using both situ hybridization immunohistochemistry, shown to be expressed neurons hence is neuropeptide. The specifically enhance neuron differentiation throughout animal by inducing interstitial cells enter pathway. Further, co-treatment with PW which inhibits differentiation, nullified effects peptides,...
Ecological developmental biology (eco-devo) explores the mechanistic relationships between processes of individual development and environmental factors. Recent studies imply that some these have deep evolutionary origins, may even pre-date divergences simplest extant animals, including cnidarians sponges. Development early diverging metazoans is often sensitive to factors, interactions occur in context conserved signaling pathways mechanisms tissue homeostasis whose detailed molecular logic...
Environmental impacts can alter relationships between a coral and its symbiotic microbial community. Furthermore, changes in the community associated with increased seawater temperatures cause opportunistic infections, disease death. Interactions soft corals their microbes are not well understood. The species Scleronephthya gracillimum is distributed tropical to temperate zones assemblages along Kuroshio Current region. In this study we collected S. from various sites at different latitudes,...
The Tetraodontidae family are known to have relatively small and compact genomes compared other vertebrates. obscure puffer fish Takifugu obscurus is an anadromous species that migrates freshwater from the sea for spawning. Thus euryhaline characteristics of T. been investigated gain understanding their survival ability, osmoregulation, homeostatic mechanisms in both seawater. In this study, a high quality chromosome-level reference genome was constructed using long-read Pacific Biosciences...
Nowadays, proliferation of jellyfish has become a severe matter in many coastal areas around the world. Jellyfish Nemopilema nomurai is one most perilous organisms and leads to significant deleterious outcomes such as harm fishery, damage equipment, moreover, its envenomation can be hazardous victims. Till now, components venom (NnV) are unknown owing scant transcriptomics genomic data. In current research, we have explored proteomic approach identify NnV their interrelation with...
Antidepressants are extensively used to treat the symptoms of depression in humans, and environmentally discharged drugs potentially threaten aquatic organisms. In this study, acute toxic effects fluoxetine (FLX) were investigated two organisms, freshwater polyp (Hydra magnipapillata) Javanese medaka (Oryzias javanicus). The median lethal concentration (LC50) FLX H. magnipapillata was 3.678, 3.082, 2.901 mg/L after 24, 48, 72 h, respectively. Morphological observations FLX-exposed showed...
Hym-301 is a peptide that was discovered as part of project aimed at isolating novel peptides from hydra. We have isolated and characterized the gene Hym-301, which encodes this peptide. In an adult, expressed in ectoderm tentacle zone hypostome, but not tentacles. It also developing head during bud formation regeneration. Treatment regenerating heads with resulted increase number tentacles formed, while treatment dsRNA reduction formed developed or The expression patterns plus these...
The spionid polychaete Polydora hoplura Claparède, 1868 is a shell borer widely occurring across the world and considered introduced in many areas. It was originally described Gulf of Naples, Italy. Adult diagnostic features are palps with black bands, prostomium weakly incised anteriorly, caruncle extending to end chaetiger 3, short occipital antenna, heavy sickle-shaped spines posterior notopodia. Bayesian inference analysis sequence data four gene fragments (2369 bp total) mitochondrial...
