Abstract:

The intertidal zone is the area between the highest and lowest tides, which represents the transition from ocean conditions to land conditions. This study aimed to determine the diversity and distribution of mollusks that exist along the intertidal zone of Nglambor Beach, between August and November 2020. Observations of all molluscs were carried out at two random stations using 10 plots measuring 1 x 1 m 2 with 5 meters. A total of two classes of Mollusca (Gastropod and Bivalvia) belonging to twelve families and 19 species were found from upper to lower an intertidal zone. The upper intertidal zone was recorded to have the highest diversity and an evenness index (Shannon-Wiener diversity index: H ’= 2.524 and Pielou evenness index: J’ = 0.932) compared to the middle and lower zones. It can be concluding that the diversity index in the study location is categorized as medium and its evenness is high. Thais hippocastanum is the most dominant species found in the upper and middle zones, while Thais tissoti dominates in the lower zone. This research contributed to a preliminary checklist on molluscs, which will support a baseline study on the intertidal in future.

Abstract:

The use of antifouling paints containing the biocide compound tributyltin (TBT) has been shown as an inductor of imposex in neogastropods mollusks. Imposex is characterized by the development of male features in females, mainly the appearance of a no functional vas deferens and penis. Samples of Thais rustica were collected in eight sites in the metropolitan area of Natal city, Rio Grande do Norte state, northeast Brazil, and examined for occurrence of imposex, which was found in many females. The higher imposex levels were presented by samples from sites near city harbor.

Abstract:

Os representantes da família Thaididae são organismos predadores de outros moluscos, perfurando suas conchas pela ação alternada de secreção oriunda do "Accessory Boring Organ" (ABO) e por raspagem através da rádula. Nesta família, o ABO está localizado na porção ventral mediano-anterior do pé. Os animais examinados neste estudo foram coletados na praia do Futuro, Fortaleza, em seguida levados ao laboratório para fixação e posterior tratamento histológico rotineiro. A porção glandular do ABO de Thais haemastoma (Linnaeus, 1758) se encontra alojada em uma cavidade circundada pela musculatura do pé e apresentando um ducto excretório que a comunica com o meio externo. Esta cavidade é revestida por um epitélio cilíndrico simples separando a porção glandular deste órgão do músculo pedioso, sendo contínuo com o epitélio de revestimento do ducto excretório. Subjacente a este tecido foi visualizado um tecido conjuntivo frouxo. A região glandular do ABO da espécie apresenta um formato discoidal com superfície irregular devido à presença de reentrâncias em direção à porção central da glândula. O epitélio glandular pseudoestratificado com células cilíndricas e ciliadas reagiu negativamente aos testes histoquímicos. Abaixo do epitélio, foi observado um tecido conjuntivo frouxo de sustentação.

Abstract:

The biological accumulation and monitoring of chemical wastes are considered with particular reference to the Solway Firth, U.K. Monitoring of the influence of chemical wastes may be concerned with somatic or reproductive responses and is more usually the former. It is shown that size and abundance are not an indication of a species fertility which is crucial to its conservation. Diet has an important influence upon the magnitude of the trace element burden of gastropod molluscs and it is shown that the fertility of Patella vulgata and Littorina littorea is unaffected by marked increases in the trace element burden. In this study, some of the species examined viz., the polychaete worms Phyllodoce maculata and Scoloplos armiger, the decapod crustacean Pagurus bernhardus and the gastropod molluscs, Littorina littorea and Thais lapillus, have a distribution which extends into arctic waters. Clearly such animals offer the opportunity for comparative studies to test the more general application of the work reported. Such comparative work would also facilitate efforts to apply data from the boreal region to problems in the Arctic.

Abstract:

Abstract Endocrine mediated "imposex" phenomenon was investigated and recorded in the muricoid gastropod species Thais carinifera during the two decades from 1993 to 2012 at three (3) sites out of six (6) localities investigated along the Sindh and Balochistan coast, Pakistan. The VDS stages 1 to 4 were apparent in Thais carinifera. The intensity of imposex has remained comparatively low in the populations of harbours in close proximity to port Mohammad Bin-Qasim, namely; Old Korangi Fish Harbour (OKFH) and New Korangi Fish Harbour (NKFH) where shipping activities are sporadic as compared to those in Manora Channel and the adjoining Karachi Port area where intensive shipping activity is rather frequent. Target species found to be good bioindicators have shown a marked decrease over the prolonged study period. Investigations show that this decrease is solely due to globally imposed effective bans on tributyltin (TBT) based antifouling paints over the past decade.

Abstract:

Rates of occurrence and degrees of imposex, and tissue concentrations of organotin compounds (tributyltin, TBT; dibutyltin, DBT; butyltin, MBT; triphenyltin, TPT; diphenyltin, DPT; and phenyltin, MPT) in the rock shell, Thais clavigera and T. bronni (Mollusca: Gastropoda) were investigated at 32 sites in Japan from May 1990 to October 1992. The rate of occurrence of imposex was 100% in both species, at almost all sites surveyed. Degrees of imposex indicated by relative penis length (RPL) index reflected the pollution levels not only of TBT, but also TPT. In heavily polluted areas, many individuals were found with oviducts which were blocked by vas deferens development, and capsule glands which were filled with aborted egg masses. These organisms were thought to be sterile.

Abstract:

The use of OTC (organotin compounds) as biocides in naval antifouling paints causes impacts on non-target organisms. One of these impacts is a syndrome called imposex in gastropod molluscs. Imposex is the imposition of male secondary sexual characteristics in female gastropods as result of endocrine disruption. In this preliminary study, imposex was observed in four out of ten sampled stations in Maceió: the city Port (100% females exhibited imposex), the Marine Emissary (23% females exhibited imposex), the Marine Terminal (35% females exhibited imposex) and Saco da Pedra beach (12% females exhibited imposex). These stations were distributed in a NE-SW orientation from the Port southwards along the coastline, following the general circulation pattern of the area. The low values of VDSI, RPSI and RPLI indicate that Maceió Coast is a less contaminated area, probably because of low shipping activities together with the fact that the sampling zone is an open coastal system and not an enclosed bay. These results suggest that the imposex development in Thais rustica may be used as a biological indicator of OTC pollution.

Abstract:

Hepatitis B virus (HBV) infection remains a major global health problem. It is therefore imperative to develop drugs for anti-hepatitis B with high-efficiency and low toxicity. Attracted by the observations and evidence that the symptoms of some patients from the Southern Fujian, China, suffering from hepatitis B were alleviated after daily eating an edible marine mollusk, Thais clavigera (Küster 1860) (TCK). Water-soluble polysaccharide from TCK (TCKP1) was isolated and characterized. The anti-HBV activity of TCKP1 and its regulatory pathway were investigated on both HepG2.2.15 cell line and HBV transgenic mice. The data obtained from in vitro studies showed that TCKP1 significantly enhanced the production of IFN-α, and reduced the level of HBV antigens and HBV DNA in the supernatants of HepG2.2.15 cells in a dose-dependent manner with low cytotoxicity. The result of the study on the HBV transgenic mice further revealed that TCKP1 significantly decreased the level of transaminases, HBsAg, HBeAg, and HBV DNA in the serum, as well as HBsAg, HBeAg, HBV DNA, and HBV RNA in the liver of HBV transgenic (HBV-Tg) mice. Furthermore, TCKP1 exhibited equivalent inhibitory effect with the positive control tenofovir alafenamide (TAF) on the markers above except for HBV DNA even in low dosage in a mouse model. However, the TCKP1 high-dose group displayed stronger inhibition of transaminases and liver HBsAg, HBeAg, and HBV RNA when compared with those of TAF. Meanwhile, inflammation of the liver was, by pathological observation, relieved in a dose-dependent manner after being treated with TCKP1. In addition, elevated levels of interleukin-12 (IL-12) and interferon γ (IFN-γ), and reduced level of interleukin-4 (IL-4) in the serum were observed, indicating that the anti-HBV effect of TCKP1 was achieved by potentiating immunocyte function and regulating the balance of Th1/Th2 cytokines.

Abstract:

For the first time, the influence ofCr (III) ionsin maximum concentration limits (MCL) from 0.5 –3 on the way of life, nutrition and digestion of Lymnaea vulnerata (Küster, 1862) and L. monnardi (Hartmann, 1844), –the different life forms of pondsnailsof the hydrographicnetwork of Ukraine,–was explored. Due to the long-term natural selectionamongthese specieswhich took place in extremely different ecological environmental conditions, the adaptive radiation of the shell of the ancient original form of pondsnailwas carried out by rheophilicL. monnardi and stagnophilicL. vulnerata,in opposite directions -divergently.The ampla-shaped shell of L. monnardi (flattened, low, compact, streamlined, with a large mouth) and a large flat sole prevent its driftingby thewater current, while the stagnicola-liketurret-shapeshell of L. vulnerata (elongated, high, narrow, with curls and flat turns, andsmall mouth)reliably protects it from excessive water consumption in the process of pulmonary respiration, thatis important for this ordinary inhabitant of mostly drying out ponds, experiencing conditions of desiccation, which hidesin the cracks of drying out bottom.The autochthonous fodder diet of these pondsnailsis represented by algae and higher aquatic vegetation (different in species composition for each of the species of mollusks studied).Under the maximum concentration limits of 0.5, MCL, 2MCL, 3MCLof Cr(III) ions in the environment, a 5-phase process of poisoningis being developed among the pond snails(0.5MCL-indifference; MCLand 2MCL-stimulation; 3MCL-depressive, sublethal, lethal phases). Its symptoms are clearly illustrated by the values ofthe main trophological parameters in poisoned individuals, depending on the course of the relevant phases of the pathological process.Key words : Lymnaea, life forms, Cr (III)ions, way of life, nutrition, digestion. Серед полютантів, які потрапляють із скидами чи стоками як у природні, так і у штучні водойми, одними з найнебезпечніших для гідробіонтів є іони важких металів. Актуальність дослідження впливу іонів важких металів на різні прояви життєдіяльності гідробіонтів пов’язана як із широкою розповсюдженістю їх наразі у поверхневих водах, так і з явно недостатнім на сьогодні ступенем дослідженості впливу значної частини із них на водних черевоногих молюсків. Саме до числа таких важких металів і належить Cr (III), рівень вмісту якого у гідромережі України. Уперше з’ясовановплив 0,5ГДКр –3ГДКр іонівCr (III) на спосіб життя, живлення і травлення Lymnaea vulnerata(Küster, 1862) i L. monnardi (Hartmann, 1844) –різних життєвих форм ставковиків гідромережі України. Внаслідок тривалого природного добору, котрий відбувався у цих тварин у вкрай відмінних екологічних умовах довкілля, адаптивна радіація черепашки прадавньої вихідної форми ставковиків здійснювалася реофілом L. monnardi і стагнофілом L. vulnerataу протилежно скерованих напрямках –дивергентно. Амплаподібна черепашка L. monnardi (сплющена, низька, компактна, обтічної форми, з великим устям) і велика плоска підошва ноги запобігають знесенням її течією, тоді як стагніколаподібна баштоподібна черепашка L. vulnerata(витягнутої форми, висока, вузька, з плоскими обертамизавитка і невеличким устям) надійно оберігає його від зайвих витрат води у процесі легеневого дихання, що важливо для цього звичайного мешканця здебільшого пересихаючих водойм, переживаючих умови десикації, забившись у щілини розтрісканого від пересиханнядна.Автохтонний кормовий раціон цих ставковиків представлений водоростями і вищою водяною рослинністю (різними за видовим складом щодо кожного з видів досліджених молюсків).За 0,5ГДКр, ГДКр, 2ГДКр, 3ГДКр іонів Cr (III) у середовищі у ставковиків розвивається 5-тифазний процес отруєння (0,5 ГДКр –байдужість; ГДКр і 2ГДКр –стимуляція; 3ГДКр –депресивна, сублетальна, летальна фази). Симптоматика його чітко ілюструється значеннями основних трофологічних показників у отруєних особин, залежних від перебігу у них відповідних фаз патологічного процесу.Ключові слова: Lymnaea, життєві форми, Cr (III), спосіб життя, живлення, травлення
