The use of biological objects in monitoring the state environment and changes caused by impact environmental pollution on marine fresh waters is a promising tool due to lower cost comparison traditional ability receive immediate information about ecosystem status. In this review, we summarize shellfish biomonitors results studies focused development bioindicator species early warning systems Russia. Since mid-1980s, Russian specialists have developed online biomonitoring systems; as rest world, there are two main approaches that currently applied study physiological status potential biosensor monitor freshwater systems: valvometry (registration gaping activity bivalve mollusks) photoplethysmography cardiac mollusks crustaceans). Valve movement responses stressors such abnormal conditions pollutants include closure shell valves for long period, decrease average distance between valves, rapid opening, higher closing frequency. Cardiac reactions stress factors increases heart rate index, variability than under normal conditions, longer periods required recovery after stress. most common bioindicators used disturbances ecosystems blue mussels, Iceland scallops, red king crabs cold-water habitats Black Sea mussels warmer well crayfish waters.

Sustainable aquaculture over the last 30 years: An analysis of the scientific literature by the Text Mining approach

Reviews in Aquaculture, Год журнала: 2024, Номер 16(4), С. 2064 - 2076

Опубликована: Июль 16, 2024

Abstract A literature search approach (using Scopus®, Elsevier© database) was established to identify peer‐reviewed articles published in English between 1960 and 2023 dealing with ‘sustainable aquaculture’ focusing on specific aquaculture practices (aquaponics, integrated multi‐trophic aquaculture, biofloc recirculating systems). Text Mining combined Topic Analysis utilized extract information from the text data of papers identified. After an appropriate screening procedure, 1111 were selected. The analysis showed a gradual increase sustainable publications over time, peaking at more than 200 2023. first biofloc, systems as alternative began appear 2010, while studies aquaponics have only been since 2015. Most (40%) came Asia, line leadership this continent aquaculture. European also considerable interest practices, Italy (leader publications), Portugal Germany researchers contributing 111 subject past 30 years. This study identified main research topics observed how these evolved. analysed dealt mainly optimization aquatic life, genetic disease management. topic protein replacement feed important, term ‘diet’ most frequently papers. subjects could serve valuable primary source, offering opportunities for deeper examination, such systematic reviews or geographic regions.

LC-MS/MS and GC-MS Analysis for the Identification of Bioactive Metabolites Responsible for the Antioxidant and Antibacterial Activities of Lygodium microphyllum (Cav.) R. Br.

Separations, Год журнала: 2023, Номер 10(3), С. 215 - 215

Опубликована: Март 20, 2023

Natural products serve as a valuable source of antioxidants with potential health benefits for various conditions. Lygodium microphyllum (Cav.) R. Br., also known Old World climbing fern, is an invasive fern native to Southeast Asia, Africa, South America, Australia, and Melanesia. It has been reported possess interesting pharmacological properties including hepatoprotective anti-inflammatory mechanisms. This study analyzed the bioactive metabolites that contribute antioxidant antimicrobial effects L. (LM) by profiling crude extract using high-resolution LC-MS/MS GC-MS systems. Several classes compounds such phenolics, flavonoids, terpenoids, steroids, macrolides, vitamins, lipids, other hydrocarbons were found in LM through non-targeted analysis. A total 74 detected LC-MS/MS, whereas nine identified GC-MS. Out 34 compounds, primarily quercetin, kaempferol, trifolin, pyroglutamic acid, arachidonic rutin antioxidant, antimicrobial, anti-inflammatory, activities. The presence phenolic flavonoid bioactivities evidence its properties.

Cadmium (Cd) is one of the highly toxic, non-essential heavy metals that inhibit plant growth and development by prompting chlorophyll loss affecting photosynthetic activities. This study investigated efficacy Spirulina platensis Sargassum polycystum extracts in alleviating Cd stress Pak Choi at morpho-biochemical, anatomical, molecular levels. Different concentrations (0, 25, 50, 100 mL/L) S. polycyctum (SAR), (SPI), a mixture both (SS) were exposed to mg/kg Cd-contaminated seedlings. Non-Cd-treated without algal assigned as positive negative controls, respectively. The results showed application increased height, fresh weight (FW), dry (DW) extract level increased. was greatest 100SS with 37.51% (shoot length), 68.91% (root 110.8% DW), 216.13% while an increase 176.7% FW) 256.9% seen 100SPI treatment. Chlorophyll a, b, carotenoid, fluorescence significantly after treatment 100SS. Antioxidant enzymes CAT, APX, POD, protein mL/L 28.13% (100SS), 36.40% (100SAR), 46.92% 153.48% same also identified dominate root structures such total length, surface area, projected diameter, volume, tips, fork number. highest reduction content shoot observed 53.8% 39.88% decrease, Increasing concentration improved leaf histological characteristics substantially, stomatal size opening, mesophyll tissues, vascular bundles. In addition, fold change ratio Rubisco gene noticeably greater than other treatments, 0.99 when compared untreated sample. present illustrated have potential effectively alleviate plants, especially mixture.

Tropical Animal Science Journal, Год журнала: 2024, Номер 47(2), С. 188 - 196

Опубликована: Июнь 1, 2024

The resistance of the Haemonchus contortus , a parasite causing severe anemia in ruminants, to commercial anthelmintics emphasizes need for alternative bio-anthelmintics. This study aimed identify molecular, chemical composition, and vitro anthelmintic activity Sargassum duplicatum against H. . Molecular identification employed Chelex method, with DNA diversity phylogeny assessed using maximum likelihood IQ-tree. analyzed composition included proximate, total flavonoid, phenols. Adult worm motility test (AWMT) egg hatch inhibiting (EHIT) were conducted at concentrations 2, 4, 6 mg/mL S. ethanolic extract. AWMT followed completely randomized factorial design (5 replications, each 5 worms), while EHIT used one-way batches from 3 adult female worms). cox1 gene sequence revealed sample as (KP101270.1) 99.83% similarity. results indicated that identified extract, observation time significantly influenced hatchability (p<0.05). Both factors exhibited significant interaction Concentrations 4-6 reduced by up 50% (LD50) within 6-8 hours, 2-6 inhibited more than 87% during 24 hours incubation. In conclusion, holds potential bio-anthelmintic agent.
