First record of two sabelline fan-worms in the tunic of the exotic sea squirt Cnemidocarpa amphora (Kott, 1992) (Stolidobranchia, Styelidae) from the Mediterranean Sea off Alexandria, Egypt

open access: yesEgyptian Journal of Aquatic Research, 2021
The sea squirt Cnemidocarpa amphora was collected from Ras El-Tin beach in the Mediterranean Sea off Alexandria, Egypt. This study identifies two small sabelline fan-worms, Parasabella minuta and Parasabella leucaspis, inhabiting the tunic of the sea ...

Comparative studies on growth, and stressor resistance of abalone (Haliotis discus) fed extruded pellets substituting tunic meal of sea squirt (Halocynthia roretzi) for fish meal and macroalgae in long term trial

open access: yesAquaculture Reports, 2022
Fish meal (FM) and macroalgae (MA) are the expensive components in abalone feeds, searching for their alternatives is of great interest to abalone aquaculture.

Wave Propagation In Water-Saturated Sand And Grain Contact Physics [PDF]

open access: yes, 2010
Measurements in sandy ocean sediments over a broad range of frequencies show that the sound speed dispersion is significantly greater than that predicted by the Biot-Stoll model with constant coefficients, and the observed sound attenuation does not seem

Think small

open access: yeseLife, 2016
The tadpole larva of a sea squirt is only the second animal to have its entire nervous system mapped out, and the results confirm that there is still much to learn from the smallest brains.

Identifying and characterizing a novel protein kinase STK35L1 and deciphering its orthologs and close-homologs in vertebrates. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:The human kinome containing 478 eukaryotic protein kinases has over 100 uncharacterized kinases with unknown substrates and biological functions. The Ser/Thr kinase 35 (STK35, Clik1) is a member of the NKF 4 (New Kinase Family 4) in the kinome

抗原および抗ヒトIgEに対する好塩基球の反応性. 1.好塩基球数の変化 [PDF]

open access: yes, 1992
Blood basophils in subjects with bronchial asthma migrate from blood stream into local allergic reaction sites after inhalation of antigen into airways. The phenomena can be observed by changes in number of basophils in the peripheral blood.

Frequency-dependent AVO attribute: theory and example [PDF]

open access: yes, 2012
Fluid-saturated rocks generally have seismic velocities that depend upon frequency. Exploring this property may help us discriminate different fluids from seismic data. In this paper, we introduce a scheme to calculate a frequency-dependent AVO attribute

Gonadal proliferation and reproductive cycle of the exotic sea squirt Cnemidocarpa amphora () (Pleurogona, Styelidae) sampled for the first time from the northern coast of Arabian Gulf in Saudi Arabia [PDF]

open access: yesBrazilian Journal of Biology, 2023
Specimens of Cnemidocarpa amphora were collected monthly from the Arabian Gulf from September 2017 to August 2018. Parts of their gonads were prepared for histological testing. The gonads’ diameters varied by month.

Investigating diet as the source of tetrodotoxin in Pleurobranchaea maculata [PDF]

open access: yes, 2014
The origin of tetrodotoxin (TTX) is highly debated; researchers have postulated either an endogenous or exogenous source with the host accumulating TTX symbiotically or via food chain transmission.
