Cone Snail Case
Cone Snail case Cone snail molecular phylogeny Cone snail video Snail Venom Yields Potent Painkiller, But Delivering The Drug Is Tricky Updated August 4, 201510:52 AM ETPublished August 3, 20153:30 PM ET http://www.npr.org/sections/health-shots/2015/08/03/428990755/snail-venom- yields-potent-painkiller-but-delivering-the-drug-is-tricky Magician’s cone (Conus magus) The magician’s cone, Conus magus, is a fish-hunting, or piscivorous cone snail found in the Western Pacific. It is so common in some of small Pacific islands, especially in the Philippines, that it is routinely sold in the market as food. The magician’s cone attacks its fish prey by sticking out its light yellowish proboscis, from which venom is pushed through a harpoon-like tooth. It hunts by the hook-and-line method and so will engulf its prey after it has been paralyzed. To learn more about hook-and-line hunters, click here. Scientists have analyzed the venom of the magician’s cone and one of its venom components was discovered to have a unique pharmacological activity by blocking a specific calcium channel (N-type). After this venom component was isolated and characterized in a laboratory, researchers realized that it had potential medical application. By blocking N-type calcium channels, the venom blocks channels that when open convey pain from nerve cells. If this is blocked, the brain cannot perceive these pain signals. It was developed as a pain management drug, and is now chemically synthesized and sold under the trade name Prialt. This drug is given to patients who have very severe pain that is not alliviated by morphine. -
The Histopathology of Antique Ark's Mantle (Anadara Antiquata) Post
The histopathology of antique ark’s mantle (Anadara antiquata) post-depuration with the shells’ filtration Nabila A. Putri, Laksmi Sulmartiwi, Kustiawan T. Pursetyo Faculty of Fisheries and Marine, Universitas Airlangga, 60115, Surabaya, Indonesia. Corresponding author: L. Sulmartiwi, [email protected] Abstract. Cockles are marine organisms which have the character of filter feeders so that heavy metals can be neutralized naturally through their shells. However, not all heavy metals can be neutralized, so depuration needs to be done. After depuration, histopathological analysis is needed to determine the condition of the soft tissue of the shells so that the disease can be diagnosed through structural changes that occur in the organs that are the main target of pollutants. This study aims to determine the histopathology of antique ark’s mantle (Anadara antiquata) after post-depuration with the filtration of the cockles’ shells. This research method applies an experimental method with scoring histological damage to antique ark’s mantle that ranges from 0 to 3, depending on the level and extent of the changes that occur. After that, the distribution of normal and non-homogeneous data was obtained, and then the Kruskal-Wallis non-parametric test was conducted. The main parameter is the histopathology of the antique ark’s mantle. Supporting parameters include water quality, namely temperature, dissolved oxygen (DO), nitrate, nitrite, ammonia, salinity, levels of heavy metals Pb and Cd, total suspended solid (TSS) and total dissolved solid (TDS). The results of the Kruskal-Wallis statistical analysis shows no significant difference between treatments P0 (Control), P1 (Filter 25%), P2 (Filter 50%), P3 (Filter 75%), and P4 (Filter 100%). -

Mollusca: Veneridae) in the Western Pacific Ocean1
Genetic Relationships among Species of Meretrix (Mollusca: Veneridae) in the Western Pacific Ocean1 Ayako Yashiki Yamakawa,2,3,6 Masashi Yamaguchi,4,5 and Hideyuki Imai4 Abstract: We compared allozymes at 12 loci in 12 populations of six species of Meretrix: M. lusoria ( Japan, Korea, and Taiwan), M. petechialis (China and Ko- rea), M. ovum (Thailand and Mozambique), M. lyrata (China), M. lamarckii ( Ja- pan), and Meretrix sp. A (Okinawa, Japan). Our allozyme results were generally consistent with the major groupings currently recognized within the genus based on morphological characters. However, we found two cryptic or un- described species: Meretrix sp. A from Okinawa and M. cf. lusoria from Taiwan. The shell characters of Meretrix sp. A were similar to those of M. lamarckii, but the species was genetically distinct (Nei’s genetic distance D > 0.845) from all other species examined. The Taiwanese Meretrix population was morphologi- cally indistinguishable from Japanese M. lusoria, although the genetic distance between the Taiwanese and Japanese populations showed a high degree of ge- netic differentiation (D > 0.386). Meretrix lusoria seedlings were introduced into Taiwan from Japan in the 1920s, and Japanese M. lusoria was previously thought to be established as a cultured stock. However, our results suggest that the Taiwanese population may represent a sibling or cryptic species of M. lusoria. Asianhardclams, genus Meretrix (Vener- (Yoosukh and Matsukuma 2001).

Department of Zoology and Aquaculture, Acharya Darwin Ch. and P Padmavathi Nagarjuna University Nagarjuna Nagar, Abstract Andhra Pradesh, India Among the various groups represented in the macrobenthic fauna of the Bay of Bengal at Prakasam P Padmavathi district, Andhra Pradesh, India, molluscs were the dominant group. Molluscs were exploited for Department of Zoology and industrial, edible and ornamental purposes and their extensive use has been reported way back from time Aquaculture, Acharya immemorial. Hence the present study was focused to investigate the diversity of Molluscan fauna along Nagarjuna University the Paleru and Moosy backwaters of Prakasam district during 2016-17 as these backwaters are not so far Nagarjuna Nagar, explored for malacofauna. A total of 23 species of molluscs (16 species of gastropods belonging to 12 Andhra Pradesh, India families and 7 species of bivalves representing 5 families) have been reported in the present study. Among these, gastropods such as Umbonium vestiarium, Telescopium telescopium and Pirenella cingulata, and bivalves like Crassostrea madrasensis and Meretrix meretrix are found to be the most dominant species in these backwaters. Keywords: Malacofauna, diversity, gastropods, bivalves, backwaters 1. Introduction Molluscans are the second largest phylum next to Arthropoda with estimates of 80,000- 100,000 described species [1]. These animals are soft bodied and are extremely diversified in shape and colour. -

Methods: Extraction of Red Sea cone snail sample with a mixture of CH2Cl2 and CH3OH (1:1, v/v) yielded 0.55 g of a green viscous material. The cytotoxic effects of the organic extract against the cancer cell lines were determined using cell proliferation (MTT) assay, and the half-maximal concentration (IC50) values measured. The effect of the crude extract on the cell cycle of the HepG-2 was determined by flow cytometry. Results: The extract produced significant inhibitory effects against SKOV-3, MDA-MB-231, MCF-7 and HepG2, with IC50 values of 22.7 ± 2.2, 68.7 ± 6.2, 47 ± 4.2 and 19 ± 2.1 µg/mL, respectively. -

Morphological and molecular analysis allowed clarifying the confused taxonomy of the largest alien ark clam species invading Italian waters and the Mediterranean Sea. Analysis of the distribution and density data demonstrated that, along the Italian coast, A. kagoshimensis is mostly found at depths of 8 to 50 m, with a catch frequency of more than 98% in the hauls involving silty-clay sediment at a depth of 8-30 m. The hotspot map clearly shows a reduction in the distribution area of the species from 2010 to 2012.
