Indeterminate Thyroid Nodules: When to Worry?
Authors: Tibbels, MPAS, PA-C Amanda
Published: January 2023

Indeterminate thyroid nodules can present a confounding scenario for both provider and patient. Once a diagnosis of an indeterminate thyroid nodule is made, appropriate management can range from conservative observation to surgical resection. A thorough evaluation, including a dedicated history and physical examination, biochemical profile, pathologic information from a seasoned pathologist, and thyroid ultrasound by an experienced radiologist can help point health-care providers in the right direction. However, the ultimate diagnosis cannot be rendered unless surgical excision is performed. Provider and patient must agree on a personalized risk vs. benefit profile for the indeterminate thyroid nodule.
Comparing Extreme Value Estimation Techniques for Short-Term Snow Accumulations
Authors: Pomeyie Kenneth , Bean Brennan , Sun Yan
Published: January 2023

The potential weight of accumulated snow on the roof of a structure has long been an important consideration in structure design. However, the historical approach of modeling the weight of snow on structures is incompatible for structures with surfaces and geometry where snow is expected to slide off of the structure, such as standalone solar panels. This paper proposes a “storm-level” adaptation of previous structure-related snow studies that is designed to estimate short-term, rather than season-long, accumulations of the snow water equivalent or snow load. One key development associated with this paper includes a climate-driven random forests model to impute missing snow water equivalent values at stations that measure only snow depth in order to produce continuous snow load records. Additionally, the paper compares six different approaches of extreme value estimation on short-term snow accumulations. The results of this study indicate that, when considering the 50-year mean recurrence interval (MRI) for short-term snow accumulations across different weather station types, the traditional block maxima approach, the mean-adjusted quantile method with a gamma distribution approach, and the peak over threshold Bayesian approach tend to most often provide MRI estimates near the median of all six approaches considered in this study. Further, this paper also shows, via bootstrap simulation, that the peak over threshold extreme value estimation using automatic threshold selection approaches tend to have higher variance compared to the other approaches considered. The results suggest that there is no one-size-fits-all option for extreme value estimation of short-term snow accumulations, but highlights the potential value from integrating multiple extreme value estimation approaches.

Application of laser technology in the removal of unwanted hair
Authors: Jankowiak Wioleta , Bartoszewicz Edyta , Jereczek Weronika
Published: January 2023

Laser hair removal requires knowledge of their physical basis and the biophysical phenomena they induce in the skin. Lasers differ in such categories as wavelenght, Energy density and laser beam size. These elements are important while selecting the right device for the skin type and individual characteristics of the patient. Knowledge of the physiology of hair and the photothermolysis that occurs during epilation, allows the treatment to be carried out correctly and safely, and the entire proces of hair elimination to be controlled. Previous studies indicate a numer of factors that determine the effectiveness of the procedure, including the parameters of the device or skin type. Despite the high degree of safety and effectiveness of the laser epilation procedure, it is also pointed out that there are undesirable consequences that may appear in response to the effects of laser light.
OKUN`S LAW IN BOSNIA AND HERZEGOVINA (1996-2021): AN EMPIRICAL ANALYSIS OF OKUN`S COEFFICIENT VARIATIONS
Authors: Amidžić Srđan , Kurteš Siniša , Kurušić Drago
Published: January 2023

Economic growth and unemployment are two macroeconomic quantities that have the greatest research interest among economists. The connection established between these two variables, which also describes their inverse relationship, is known in the literature as Okun's law. The subject of this research was to examine Okun's regularity between the movement of gross domestic product and unemployment in Bosnia and Herzegovina during the period from 1996 to 2021. We divided the observed period into two parts, and we observed the total sample, pre-crisis and post-crisis period, and we took 2008 and the economic crisis as the relevant year. The aim of the work was to quantify Okun's coefficient for the entire sample, pre-crisis and post-crisis period. The research results showed the existence of Okun's coefficient with variations of the coefficient over time. Namely, the value of the coefficient in the period from 1996 to 2008 is higher in absolute terms compared to the entire period, as well as the post-crisis period. The value of the coefficient for Bosnia and Herzegovina in the precrisis period was 0.79, and 0.66 is the calculated value of the coefficient for the post-crisis period. The coefficient value of 0.76 was calculated for the period from 1996 to 2021. From this we can conclude that the elasticity of the coefficient in Bosnia and Herzegovina is higher in the post-crisis period compared to the pre-crisis period.
CUSTOMS AS AN ELEMENT OF ENRICHING THE RURAL TOURIST OFFER - A CHANCE FOR TOURISM DEVELOPMENT AFTER THE CRISIS
Authors: Cvijanović Drago , Pantović Danijela , Petrović Tijana
Published: January 2023

Modern tourists are looking for new experiences, i.e. they no longer focus on familiar types of vacation. Rural areas with their material and spiritual heritage can create a product according to the expectations and needs of modern tourists. The 2008 financial crisis and the current health crisis caused by the COVID - 19 pandemic have changed preferences and tourism demand in general. This paper focuses on changes in tourist demand caused by the consequences of the crisis and traditional customs that can be used to differentiate the tourist offer. The initial assumption is that tourists want to escape from urban areas and spend their holidays in rural areas. The results indicate that rural areas have numerous potentials, which, combined with customs, can influence tourists to visit these areas more extensively.
ANALYSIS OF THE BONUS SYSTEM IN INSURANCE USING MARKOV CHAINS
Authors: Fulurija Mladen
Published: January 2023

One of the ways in the insurance premium calculation procedure is to determine the premium based on experience. A significant role belongs to the so-called bonus system in practical examples of determining the number of insurance premiums. The procedure for applying this system is based on the previous compensation claims analysis, in the operationalization of which the application of Markov chains occupies a pivotal place. The goal is to show and point out the importance of Markov processes and one of the segments of their application in an appropriate way, which in this case is the insurance field. This paper deals with the bonus system used in motor vehicle insurance. Insurance users fall into three discount categories, and an analysis of the number of future premiums was performed depending on the damages incurred and the probability of their reporting. It has been shown that there may be a disproportion between the current amounts of premiums to be paid and the amounts of reported claims. This situation arises due to the small number of discount categories and slight differences in discount levels. The paper also discusses the possibility of analyzing future premiums depending on the damage done and the probability of its reporting in particular cases of an insured individual.

In this study, we define Pauli–Leonardo quaternions by taking the coefficients of the Pauli quaternions as Leonardo numbers. We give the recurrence relation, Binet formula, generating function, exponential generating function, some special equalities, and the sum properties of these novel quaternions. In addition, we investigate the interrelations between Pauli–Leonardo quaternions and the Pauli–Fibonacci, Pauli–Lucas quaternions. Moreover, we create some algorithms that determine the terms of the Pauli–Leonardo quaternions. Finally, we generate the matrix representations of the Pauli–Leonardo quaternions and ℝ-linear transformations.

Cruise CAGE 14-1 is one of several cruises in 2014 that will be carried out to collect cross-disciplinary data for addressing the objectives of the Norwegian Centre for Arctic Gas Hydrate, Environment and Climate, CAGE. The Norwegian Research Council funds CAGE for a period of 10 years to addressee main scientific questions about gas hydrate environments in Arctic regions.
Cruise CAGE 14-1 was also hosting this year’s AMGG research school cruise with 14 PhD students participating, most of them from CAGE. The cruise focused on acquisition of seismic, oceanographic, atmospheric, geochemical and sediment and benthic fauna sampling data from three target areas:
the shallow shelf and shelf edge methane seepage sites at Prins Karls Forelanda sediment drift on the western flank of the Knipovich Ridgethe Vestnesa Ridge
Research objectives were planned long the goals of CAGE and its individual work packages, and the teaching would be organized along these goals.
Scientific problems that are to be addressed in these two key target areas include the periodicity of seepage (i.e. time scales of active, inactive and reactivated systems), quantification of methane concentrations in surface sediments, water column and above the sea surface, gas and hydrates, the nature of gas sources, and the benthic communities occurring at the seep sites.
Specific objectives of cruise CAGE 14-1 were as follows:
Hydro-acoustic mapping of methane bubble plumes above shallow and deep-water vent fields.Seismic surveying and multibeam mapping across the contours of the Svyatogor Rise.Sediment sampling using gravity, box and multi-corer for sediment and pore-water geochemical analysesSampling of benthic fauna at several seep sites and reference stations in all three target areas.Acquisition of oceanographic data for measuring oceanographic conditions and methane concentrations in the water column, particularly at the shallow shelf sites.

CAGE 14-5 cruise allowed to study the gas release from gas hydrated sub-seabed environments  at the continental margin off NW and N-Svalbard and the transport and distribution of methane within the water column. We carried out acoustic profiling (18, 38 and 120 kHz) in the water column, CTD water sampling for gas analyses, seismic profiling (mini  GI  guns), bathymetry mapping (EM300), and sediment gravity coring (3m corer). Though water above gas flares may be enriched in methane, methanotrophic microbescan reduce the methane concentrations and thus the amount of methane that may escape from the seabed to the ocean, one of the topics investigated during this cruise

CAGE16-5 Cruise Report: ROV-based Geological and Biological Investigations of Methane Seeps at Prins Karls Forland, Storfjordrenna Pingos and Bjørnøyrenna Craters
Authors: Carroll Michael L.
Published: January 2023

The cruise was an activity in of the Centre of Excellence for Gas Hydrate, Environment and Climate (CAGE) at UiT – The Arctic University of Norway.
The overall aim of the cruise was to utilize the NTNU/AMOS SK30k ROV for seafloor mapping and targeted sample collection at selected CAGE sites, focusing on methane seepage areas west and south of Svalbard.
More specific objectives of the cruise were to:
Use an ROV-mounted multibeam system to acquire very high resolution (10cm) seabed bathymetry in areas of methane seepsConduct detailed visual seabed surveys for habitat mapping and photomosaicking at specific seep featuresCollect seabed samples of authigenic carbontate crusts, sediments, microbes, foraminifera and macro organisms associated with methane seeps from the ROV, and complimented with more traditional sampling methodsContinue time series investigations of water column measurements of methane concentrations, and of methane oxidizing microbes in the seawaterNet sampling for planktic forams at seeps
Sampling activities were designed with a multi-disciplinary approach, with research groups from all CAGE work packages working together in the same locations to develop a holistic understanding of the geological, oceanographic and biological components at key methane seep sites. This cruise prioritized the acquisition of information for mapping seabed features and habitat characterizations (e.g. photomosaicking, visual information) combined with in-situ site sampling using ROV technologies, and complimented by our ‘traditional’ technologies (e.g. CTD, net, and coring devices).
With these objectives in mind, the strategy for each of the selected locations is to first carry out visual survey work to acquire framework measurements and data to be of use for all groups within CAGE, followed by a consolidated sampling plan to satisfy the needs of individual researchers for sample material

A novel approach for Arabic business email classification based on deep learning machines
Authors: Masri Aladdin , Al-Jabi Muhannad
Published: January 2023

During the last decades, the reliance on email communication, especially in business, has increased significantly. Companies receive a massive amount of emails daily, that include business inquiries, customers’ feedback, and other types of emails. This inspired many researchers to propose different algorithms to classify and redistribute the numerous emails according to their content. Nowadays, emails containing Arabic text, especially in the Arab world, have raised an increasing concern since they became widely used in official correspondence. Nevertheless, just a small amount of literature focuses on Arabic text classification. Therefore, this work addresses Arabic business emails classification based on natural language processing (NLP). A dataset of 63,257 emails was used and the emails were classified as: urgency, sentiment, and topic classification. The proposed models are based on machine learning techniques and a lexicon of words on which the emails are identified. The models are composed of different settings of convolutional neural networks (CNN). A separate model was built, trained, and tested for each category. The results were promising and gave an accuracy of about 92% and a loss of less than 8%. They also proved the correctness and robustness of this work.
Change in eating habits during the Spanish COVID-19 pandemic lockdown: evidence for a sample of university community
Authors: Cantarero Prieto David , Lanza-León Paloma , Moreno Patricia , Blázquez-Fernández Carla , Lera Javier , Gonzalez-Diego Francisco-Jose , González Rodríguez Irene
Published: January 2023

Background

The stress and anxiety caused by COVID-19 lockdown may have changed the eating habits of the population. Our aim is to assess the eating changes that have taken place due to the pandemic.

Methods

Data were collected through an electronic survey created by the Health Economics Research Group of the University of Cantabria and IDIVAL and conducted between 14/01/2021 and 19/02/2021. A total of 1,417 responses were recorded, but only 507 complete observations were considered. We carried out a cross-sectional analysis through ordered probit regressions.

Results

The improvement in post-confinement eating habits is associated with higher income level, better self-assessed health status and more physical activity. The worsening of eating habits is associated with having a certain level of nomophobia or the fear of contagion.

Conclusions

Our analysis can be used for designing and implementing new strategies to overcome the negative spill overs of the COVID-19 pandemic and improve the dietary patterns.
Facilitation of a free-roaming apex predator in working lands: evaluating factors that influence leopard spatial dynamics and prey availability in a South African biodiversity hotspot
Authors: Greyling Eugene , Comley Jessica , Cherry Michael I. , Leslie Alison J. , Müller Lana
Published: January 2023

Apex predators ideally require vast intact spaces that support sufficient prey abundances to sustain them. In a developing world, however, it is becoming extremely difficult to maintain large enough areas to facilitate apex predators outside of protected regions. Free-roaming leopards (Panthera pardus) are the last remaining apex predator in the Greater Cape Floristic Region, South Africa, and face a multitude of threats attributable to competition for space and resources with humans. Using camera-trap data, we investigated the influence of anthropogenic land modification on leopards and the availability of their natural prey species in two contrasting communities—primarily protected (Cederberg) and agriculturally transformed (Piketberg). Potential prey species composition and diversity were determined, to indicate prey availability in each region. Factors influencing spatial utilisation by leopards and their main prey species were also assessed. Estimated potential prey species richness (Cederberg = 27, Piketberg = 26) and diversity indices (Cederberg—H′= 2.64,Ds= 0.90; Piketberg—H′= 2.46,Ds= 0.89), supported by both the Jaccard’s Index (J= 0.73) and Sørensen’s Coefficient (CC= 0.85), suggested high levels of similarity across the two regions. Main leopard prey species were present in both regions, but their relative abundances differed. Grey rhebok, klipspringer, and rock hyrax were more abundant in the Cederberg, while Cape grysbok, Cape porcupine, chacma baboon, and common duiker were more abundant in Piketberg. Leopards persisted across the agriculturally transformed landscape despite these differences. Occupancy modelling revealed that the spatial dynamics of leopards differed between the two regions, except for both populations preferring areas further away from human habitation. Overall, anthropogenic factors played a greater role in affecting spatial utilisation by leopards and their main prey species in the transformed region, whereas environmental factors had a stronger influence in the protected region. We argue that greater utilisation of alternative main prey species to those preferred in the protected region, including livestock, likely facilitates the persistence of leopards in the transformed region, and believe that this has further implications for human-wildlife conflict. Our study provides a baseline understanding of the potential direct and indirect impacts of agricultural landscape transformation on the behaviour of leopards and shows that heavily modified lands have the potential to facilitate mammalian diversity, including apex predators. We iterate that conservation measures for apex predators should be prioritised where they are present on working lands, and encourage the collaborative development of customised, cost-effective, multi-species conflict management approaches that facilitate coexistence.

Published: January 2023

Background

The Tibetan Plateau has an abundance of yak milk resources. The complex microbiota found in traditional fermented yak milk produced and sold by local Tibetans endows the yak milk with unique quality characteristics such as tissue morphology, flavor, and function. However, the diversity of bacterial flora in traditional fermented yak milk have not been elucidated.

Methods

In this study, 15 samples of fermented yak milk were collected for 16S rRNA high-throughput sequencing to analyze the bacterial community composition and function.

Results

After filtering for quality, 792,642 high-quality sequences were obtained, and 13 kinds of different phyla and 82 kinds of different genera were identified, of which the phylum Firmicutes (98.94%) was the dominant phylum, Lactobacillus (64.73%) and Streptococcus (28.48%) were identified as the dominant genus, in addition, the bacterial community richness and diversity were higher in Manang Village, followed by Bola Village. Bacterial community richness and diversity in Huage Village were relatively low. Based on the Kyoto Encyclopedia of Genes and Genomes (KEGG) functional classification, the microorganisms in traditional fermented yak milk have rich metabolic functions (77.60%). These findings suggest that a large number of bacteria in traditional fermented yak milk contain abundant metabolic genes and can carry out a variety of growth and metabolic activities. This study established a theoretical foundation for further exploring the microbial flora of traditional fermented yak milk in Gannan.
Response of photosynthesis, the xanthophyll cycle, and wax in Japanese yew (Taxus cuspidata L.) seedlings and saplings under high light conditions
Authors: Li Wei , Li Jiacheng , Wei Jia , Niu Chunda , Yang Deguang , Jiang Baiwen
Published: January 2023

In order to understand the adaptative changes of the Japanese yew (Taxus cuspidate L.) to high light conditions, this study investigated gas-exchange, chlorophyll fluorescence, chlorophyll, and the impact of epicuticular wax on the gas-exchange and photoinhibition of Japanese yew seedlings and saplings. The chlorophyll content per unit area and photosynthetic rate in seedling leaves were significantly lower than in sapling leaves. When leaves from seedlings and saplings were exposed to 1,200 μmol·m−2·s−1 photon flux density (PFD) for 2 h, seedling leaves exhibited a greater down-regulation of maximum quantum yield (Fv/Fm) and actual photosystem II efficiency ($\Phi$PSII). Non-photochemical quenching (NPQ) and high energy quenching (qE) in sapling leaves were much higher than in seedling leaves when both were exposed to 1,200 μmol·m−2·s−1 PFD for 2 h. At a low level of O2, the photorespiration rate (Pr) and the ratio of photorespiration/gross photosynthetic rate (Pr/Pg) in seedling leaves were lower than in sapling leaves when both were exposed to 1,200 μmol·m−2·s−1 PFD, but this difference did not reach statistical significance (P < 0.05). Compared with sapling leaves, seedling leaves exhibited lower levels of xanthophyll pool. Epicuticular wax content on seedling leaves was significantly lower than on sapling leaves. The results of this study showed that wax coverage on the leaf surface decreased the photosynthetic rate in sapling leaves as a consequence of decreased stomatal conductance. Epicuticular wax is related to tree age and photoinhibition prevention in the Japanese yew. It is possible that lower photosynthetic rate, lower NPQ depending on the xanthophyll cycle, and lower deposition of epicuticular wax results in seedling plants that are not adapted to high light conditions.

Information security is a topic that has been increasingly discussed nowadays after the beginning of the pandemic and its understanding has been fundamental to protect information in several organizations. The present study aims to identify and analyze the application of threat modeling in digital transformation from the perspective of information security risks. For the development of the research, a systematic review of the literature was conducted with the adoption of a protocol based on PRISMA-P to identify which threat modeling techniques have been applied in digital transformation and which information security risk approaches are used in the application of the threat modeling. The result of this study suggests that threat modeling applied in digital transformation uses customized models by means of unspecified techniques and that qualitative risk approaches have been adopted more frequently in digital transformation.

Carcinoid syndrome consists of the classic symptom triad of flushing, diarrhoea, and valvular heart disease. It occurs in the majority of patients with liver metastases. This report presents a 68-year-old female who suffered from chronic diarrhoea with a history of multiple admissions for the same. On evaluation, a Computed Tomography (CT) scan showed a terminal ileal lesion and bulky ovaries. Suspecting Neuroendocrine Tumour (NET) with carcinoid syndrome, a Gallium 68 DOTANOC (DOTA-1-Nal3- octreotide) scan was done which revealed somatostatin receptor expression in enhancing soft tissue lesion in terminal ileum as well as in bilateral adnexa. This confirmed the diagnosis of NET of the ileum and bilateral ovarian metastases. The patient underwent laparoscopic curative resection of the primary tumour along with bilateral oophorectomy. The patient was diagnosed with ileal NET and presented with clinical symptoms of carcinoid syndrome, yet did not have evidence of hepatic metastasis, but instead had bilateral ovarian metastasis which itself is a rare entity.

Authors: Salian Shrishti Satish , Dhadse Prasad V
Published: January 2023

Introduction: The focus of root coverage procedures is now shifting to minimally invasive surgical approaches. Periodontists are being required to adopt newer and more unique procedures to thoroughly cover the exposed roots. Due to the sensitivity of various techniques and the fact that it involves a wide variety of operations and their variants, periodontal plastic surgery provide a substantial challenge. A variety of minimally invasive techniques and platelet concentrates which are abundant in growth factors have been assimilated that provide the added benefit of better and rapid healing. Aim: This study aims to evaluate the effectiveness of TitaniumPrepared Platelet Rich Fibrin (T-PRF) and Platelet Rich Fibrin (PRF) membrane in Miller’s Class-I and Class-II multiple Gingival Recession (GR) using Modified-Vestibular Incision SupraPeriosteal Tunnel Access (M-VISTA) technique. Materials and Methods: The planned protocol would be randomised clinical trial and will be performed over a period of two years. Twenty-two patients will be selected according to the inclusion criteria, each having multiple GR (>2 mm, Class I or II recession) on buccal/labial aspects of teeth in maxilla or mandible, and would be randomly distributed into the two groups (control and test). The M-VISTA technique would be carried out for root coverage using T-PRF (test group) and PRF (control), respectively as regenerative materials and their effectiveness will be compared by measuring the Pocket Probing Depth (PPD), Clinical Attachment Level (CAL), Relative Gingival Marginal Level (RGML), Recession Depth (RD) and Width of Keratinised Gingiva (WKG). Student’s paired and unpaired t-tests will be used to evaluate data from the baseline to 3 and 6 months for each group. Expected Results: The authors expect better results of root coverage using the M-VISTA technique in combination with T-PRF (test group). Better results in terms of PPD, CAL, RGML, RD, and increase in thickness of attached gingiva are expected. Conclusion: Combined effect of using T-PRF in the M-VISTA procedure is expected to improve the periodontal parameters including, the soft tissue outcomes and the plaque and bleeding index.
Bifurcated Arc of Buhler Co-existent with an Arc of Riolan-A Rare Case Report
Authors: Ramamurthy Sarah , Pratap Harsha
Published: January 2023

The Arcs of Buhler and Riolan are collateral channels that connect the major midline ventral branches of the abdominal aorta, which supply the gastrointestinal tract. These arcs occur with a relative rarity of 1-10%. During routine dissection of the abdominal cavity of a 50-year-old, embalmed male Indian cadaver in the Department of Anatomy of a National Institute in South India, the presence of a large vertical tortuous bifurcated artery was noticed, posterior to the body of the pancreas, connecting the coeliac trunk to the superior mesenteric artery. This was identified to be an Arc of Buhler (AOB) and measuring 8 mm in external diameter. In addition, an Arc of Riolan (AOR) was identified, connecting the left division of the Buhler’s arc to the left colic artery. The presence of a large bifurcated AOB or its co-existence with an AOR has not been described previously. The identification of such anastomotic channels in symptomatic patients may help in diagnosing impending bowel ischemia. Aneurysms of AOB, though rare, are life-threatening and have been treated successfully. The knowledge of mesenteric vascular anatomy is important during abdominal surgeries and endovascular procedures. Recognising a vascular variation is crucial to avoid inadvertent bleeding or bowel ischaemia.

The evaluations of insects’ protein as viable alternative protein source in fish diets are gaining more attention revealing that the protein has more comparative advantage than other protein sources. Therefore, this study was conducted to isolate and identify (using phylotypic and genotypic methods) bacteria isolates in the gastrointestinal tract (GIT) of African hybrid catfish fed supplemented grasshopper meal. Four feeding diets were adopted in this study; Diet A (conventional feed), Diet B (100% Grasshopper meal), Diet C (50% fishmeal and 50% Grasshopper meal) and Diet D (100% Fish meal). At the end of the 12- week experimental period, the fish were sacrificed for their GIT contents to determine bacteria diversity. In the catfish fed diet A, the bacteria isolates identified were Streptococcus pyogenes, Enterobacter aerogene, Staphylococcus aureus, Shigella flexneri, Escherichia coli, Leuconostoc latis and Klebsella pneumonia. In catfish fed diet B, Bacillus subtilis, Lactococcus bulgaricus, Lysinibacillus macroides, Lysinibacillus capsici, Stenotrophomonas pavanii and Lysinibacillus sp were isolated. Similarly, the fish fed diet C recorded the presence of Bacillus subtilis, Lactococcus bulgaricus, Lysinibacillus sp., Staphylococcus aureus, Lysinibacillus macroides, Stenotrophomonas pavanii and Enterobacter aerogene. The bacteria isolated in the GIT of fish fed diet D were Bacillus cereus, Staphylococcus aureus, Pedicoccus acidilactis, Escherichia coli, Salmonella typhi, Leuconostoc latis and Shigella flexneri.  Probiotic bacteria were more in fish fed with diets B and C, an indication that the different ratio of supplemented grasshopper meal is good for the fish, as they have the potentials to boost the fish immune system and improve the microbial balance of its gastro-intestinal tract.

Published: January 2023

Aim: To investigate the molluscicidal activity of aqueous extracts of Phyllanthus niruri  and Euphorbia tirucalli  on fresh water snails Lymnaea (Radix)  acuminata and Indoplanorbis exustus (as target organisms) and on  Channa punctatus fish ( as non target organism),sharing the same habitat.

Methodology: The aqueous extracts of the stem bark and leaves of  Phyllanthus niruri ( a tropical small herb, commonly known as a Bhumi Amla), belonging to the family Phyllanthaceae and the aqueous extracts of stem bark and latex of Euphorbia tirucalli (a semi-arid tropical plant, commonly called milk bush) of the family Euphorbiaceae, were investigated as plant origin molluscicides, against freshwater snails, responsible for causing fascioliasis, Lymnaea (Radix) acuminate and Indoplanorbis exustus, as well as on Channa punctatus ,using Singh and Agarwal method and POLO computer program.

Results: A significant time and dose-dependent effect of aqueous extracts of both the plants against the freshwater snails were observed. Thus increase in exposure time, the LC50 of Phyllanthus niruri stem and leaf extracts were decreased from 267.89 mg DW/L (24h) > to 180.64mg DW/L (96h) against Lymnaea acuminata and 261.49 mg DW/L (24h)> to 136.40 mg DW/L (96h) against Indoplanorbis exustus. Likewise, the LC50 of aqueous extract of latex of Euphorbia tirucalli were decreased from 1.80 mg DW/L (24h) >to 0.65 mg DW/L (96h) against Lymnaea acuminata and 0.90 mg DW/L (24h)> to 0.28 mg DW/L (96h) against Indoplanorbis exustus, with the increase in exposure time. Its aqueous stem bark extract showed a similar pattern.  These aqueous plant extracts at higher doses were also observed to be lethal to freshwater fish Channa punctatus, which share a common habitat with the freshwater snails, but the doses LC90, (24h) of snails didn’t cause any mortality to these fishes, thus indicating that these plant extracts can be safely used as molluscicides.
