Effects of Lotus Flower Extract on Cotton Fabric and Its Antimicrobial Activity against Wound Causing Pathogens
Authors: Bhuvaneswari S , Suseela J.
Published: August 2024

Background:

Hemp that belongs to the cannabis plant has been used for medicinal purposes for centuries due to the purposes that contained natural plant products. Of all these types, lotus flower extract obtained from the Nelumbo nucifera has been considered to possess some antibacterial activity. This study seeks to evaluate the effectiveness of bacteriostatic activity of lotus flower extract incorporated into fabrics used in coating the dressing.

Methods:

Leaves of lotus were used and subjected to extraction using methanol and diethyl ether solvents. These extracts were then practiced in a Petri dish plate against the specific pathogens of wound infections obtained from Microbial Type Culture Collection (MTCC). According to the type of cell wall, the pathogens were divided into Gram-positive cocci: Staphylococcus aureus and Streptococcus pyogenes, and Gram-negative: Escherichia coli and Pseudomonas aeruginosa. The antimicrobial effectiveness was tested by means of the disc diffusion method. The phytochemical component was also screened as a way of determining the secondary metabolites present in the extracts.

Results:

Alkaloids, anthraquinone, flavone, saponin, glycoside, tannin, phenol and cardiac glycoside were present in the Phytochemical analysis of extracts of O.moschata. The antibacterial tests on bacterial species’ growth revealed that all the extracts were moderately effective against S. aureus, showing the zone of inhibition between 5 – 10 mm, whereas against P. aeruginosa and E. coli the extracts were highly effective with a zone of inhibition between 7 – 15 mm.

Conclusion:

In the case of this research, it is clearly depicted that lotus flower extracts have strong antibacterial properties especially against the Gram-negative bacteria namely P. aeruginosa and E. coli. These findings are in concordance with the ethno medial usage of lotus plant in treating infected wounds and opens up applications in using the extracts to develop antibacterial fabric scarf solutions. More related works should be conducted to investigate the clinical utility and effectiveness of the above extracts in wound healing and their safety.
A Survey Study on the Use of Music for Self-care during Menopause
Authors: Balasubramanian Sruthee , Mukherjee Baishali , Sundar Sumathy
Published: August 2024

Introduction:

Menopause is a natural stage in the life of all women. However, the psychophysiological changes as a result of menopause can be difficult to cope with, resulting in various symptoms such as anxiety, depression, physical pain, hot flashes, and cognitive disturbances and deterioration in the quality of life of women facing these symptoms. Alternative and complementary therapies such as music therapy may be useful in coping with the common symptoms of menopause. Using music for self-care may have positive effects on the mind and body of women experiencing various psychophysiological symptoms of menopause.

Aim and Objectives:

The survey aims to understand if and how women use music for self-care during the menopausal phase. The survey questionnaire focuses on understanding the effects of music and whether it has been a useful resource in coping with the symptoms of menopause experienced by women. The symptoms of menopause focused on this study include stress, changes in mood, pain, and sleep quality. The study also aims to understand whether women engage in music actively while experiencing the symptoms of menopause, the methods used, and the musical experiences involved while engaging in music during menopause.

Methods:

This is a survey questionnaire-based study to understand the use of music for self-care during menopause and the effects of music on women during the menopausal phase. The study uses a qualitative descriptive method of research to get an in-depth analysis and understanding of how women use music for self-care. The study formed dimensions based on the themes that were derived through the questions and responses received from the participants. Responses were analyzed under these dimensions, and the results were elaborated qualitatively in a detailed and descriptive manner.

Results:

(a) Awareness about music for self-care: Only 17.5% of participants used music regularly for self-care during menopause. A higher percentage of educated women (PG or higher) were more aware, yet overall awareness was low. (b) Psychophysiological symptoms: 90% used music to relax when stressed, 55% to regulate mood, and over 60% for pain management. Mixed effects were seen on sleep quality. (c) Active engagement: 42.5% did not actively engage in music for managing symptoms. Film music was the most preferred genre. (d) Mind–body responses: Participants reported increased mindfulness (50%) and happiness (50%). (e) Other methods: More than 50% resorted to chanting/prayer and over 30% to yoga and meditation.

Conclusion:

Awareness and proactive use of music for self-care remain limited; the findings demonstrate significant benefits, particularly in stress relief, mood regulation, pain reduction, and improved sleep quality.
Factors associated with precancerous stomach lesions and progresion: A 7-year multi-center prospective cohort study on the low incidence of gastric cancer in central Saudi Arabia
Authors: Zacharakis Georgios , Dahale Amol , Elbary Elsayed R.A. Abd , Babikir Rawan R.E. , Alla Motaz A.N. , Mustafa Mohamed O.
Published: August 2024

Background:

In Saudi Arabia (SA) no data are available on precancerous stomach lesions (PSLs) or the associated risk factors. We aimed to identify PSLs and investigate factors associated with PSLs and their progression.

Methods:

This 7-year prospective study screened for PSLs in asymptomatic Saudi patients aged 45–75 years in central SA (n = 35,640). Those who had high-sensitivity guaiac fecal occult blood tests (HSgFOBT+) and negative colonoscopy results (n = 1242) were subjected to upper GI endoscopy to identify PSLs and were followed up every 3 years or earlier, depending on the type of PSL. Factors associated with PSLs were investigated.

Results:

The 7-year participation rate was 86.9% (1080/1242). The 7-year prevalence of PSLs was 30.9% (334/1080). The incidence rate of PSLs was 134 new cases/100,000 population/year, total population at risk - 35,640 and 44.3 new cases/1,000 persons/year among the 1080 participants with HSgFOBT+ and negative colonoscopy results. Among the 334 participants with PSLs, 8 (2.4%) had neoplastic progression to GC during the surveillance period. Age, Helicobacter pylori infection, smoking status, a diet with preserved salty foods, low income, and a family history of GC were associated with PSLs.

Conclusions:

The incidence of GC is low in central SA, but screening for PSLs among participants with HSgFOBT+ and negative colonoscopy findings may contribute to the early detection and subsequent treatment of GC. HP eradication, not smoking, normal body weight, and adhering to a healthy diet seem to be potential factors associated with the development of PSLs. Further studies are needed to search if such interventions would decrease the incidence of PSLs and progression to early GC.

Cerebrospinal fluid (CSF) leaks originating from defects within the anterior and middle cranial fossa typically manifest as unilateral clear watery rhinorrhea. Continuous CSF leakage mandates surgical repair due to the risk of meningitis and brain abscess. It can be categorized based on its underlying etiology into traumatic, iatrogenic and non-traumatic CSF leaks.
Morse-Smale diffeomorphisms with non-wandering points of pairwise different Morse indices on 3-manifolds
Authors: Pochinka Olga Vital'evna , Talanova Elena Anatol'evna
Published: August 2024

We consider the class $G$ of orientation-preserving Morse-Smale diffeomorphisms $f$ defined on a closed 3-manifold $M^3$, whose
non-wandering set consists of four fixed points with pairwise different Morse indices. It follows from results due to Smale and Meyer that all gradient-like flows with similar properties have a Morse energy function with four critical points of pairwise distinct Morse indices. This means that the supporting manifold $M^3$ of such a flow admits a Heegaard decomposition of genus 1, so that it is diffeomorphic to a lens space $L_{p,q}$. Despite the simple structure of the non-wandering set of diffeomorphisms in the class $G$, there are diffeomorphisms with wildly embedded separatrices. According to results due to Grines, Laudenbach, and Pochinka, such diffeomorphisms have no energy function and the question of the topology of the supporting manifold is still open. According to results due to Grines, Zhuzhoma, and V. Medvedev, $M^3$ is homeomorphic to a lens space $L_{p,q}$ in the case of a tame embedding of the one-dimensional separatrices of the diffeomorphism $f\in G$. Moreover, the wandering set of $f$ contains at least $p$ non-compact heteroclinic curves. We obtain a similar result for arbitrary diffeomorphisms in the class $G$. On each lens space $L_{p,q}$ we construct diffeomorphisms from $G$ with wild embeddings of one-dimensional separatrices. Such examples were previously known only on the 3-sphere. We also show that the topological conjugacy of two diffeomorphisms in $G$ with a unique non-compact heteroclinic curve is fully determined by the equivalence of the Hopf knots that are the projections of one-dimensional saddle separatrices onto the orbit space of the sink basin. Moreover, each Hopf knot $L$ can be realized by such a diffeomorphism. In this sense the result obtained is similar to the classification of Pixton diffeomorphisms obtained by Bonatti and Grines.

On extensibility and qualitative properties of solutions to Riccati's equation
Authors: Astashova Irina Viktorovna , Nikishov Vladimir Andreevich
Published: August 2024

We consider Riccati's equation on the real axis with continuous coefficients and non-negative discriminant of the right-hand side. We study the extensibility of its solutions to unbounded intervals. We obtain asymptotic formulae for its solutions in their dependence on the initial values and the properties of the functions representing roots of the right-hand side of the equation. We obtain results on the asymptotical behaviour of solutions defined near $\pm\infty$. We study the structure of the set of bounded solutions in the case when the roots of the right-hand side of the equation are $C^1$-functions which are different on the whole of their domain and tend monotonically to some limits as $x\to\pm\infty$. We extend, improve, or refine some well-known results.

Minimax solutions of Hamilton-Jacobi equations in dynamic optimization problems for hereditary systems
Authors: Gomoyunov Mikhail Igorevich , Lukoyanov Nikolai Yur'evich
Published: August 2024

A survey of the results concerning the development of the theory of Hamilton-Jacobi equations for hereditary dynamical systems is presented. One feature of these systems is that the rate of change of their state depends not only on the current position, like in the classical case, but also on the full path travelled, that is, the history of the motion. Most of the paper is devoted to dynamical systems whose motion is described by functional differential equations of retarded type. In addition, more general systems described by functional differential equations of neutral type and closely related systems described by differential equations with fractional derivatives are considered. So-called path-dependent Hamilton-Jacobi equations are treated, which play for the above classes of systems a role similar to that of the classical Hamilton-Jacobi equations in dynamic optimization problems for ordinary differential systems. In the context of applications to control problems, the main attention is paid to the minimax approach to the concept of a generalized solution of the Hamilton-Jacobi equations under consideration and also to its relationship with the viscosity approach. Methods for designing optimal feedback control strategies with memory of motion history which are based on the constructions discussed are presented.

Liftgate Slam by Bilinear Quasistatic Approach Using Modal Transient
Method under Equivalent Static Loads
Authors: Chatterjee Suprakash
Published: August 2024

Automotive closure slam is the most crucial attribute affecting the closure
structure and its mountings on BIW due to its high occurrence in real-world
usage. Thus, virtual simulation of closure slam becomes necessary and is
generally carried out using explicit codes with associated technical hitches
like all-requisite inputs availability, FE modeling and analysis techniques,
substantial human effort, high solution time, human and computational resource
competence, or even access to suitable expensive explicit FE solver. Hence it
becomes challenging to virtually analyze the design at every design phase of
product development cycle under strict timelines leading to possibilities of
both over- and under-designed parts, sometimes resulting in physical testing or
even field failures. So, the need for an alternative simplified representation
of closure slam, addressing the typical issues faced during explicit dynamic
simulation and producing acceptable analysis outputs, gains significance. In
this article the rotation of the liftgate about its hinge axis during slam is
first segregated into two successive rotation phases based on the geometric
configuration of its latch/locking components in terms of initial state to
half-latched and half-latched to full-latched condition. Linear springs are
introduced at critical locations in the FE model and the two rotation phases are
initially represented by two linear static analysis, under equivalent static
loads, determined using kinematic and inertia properties relationships at a
particular operating velocity. This is followed by modal transient analysis on
the linear static analysis setups in successive time domains in accordance to
the rotation phase. Kinematic and inertia properties compliance are ensured
during each phase. The combined modal transient analysis results, representing
the entire event, shows outputs consistent with explicit dynamics simulation and
stress history in tandem with the loading dynamics, thus resulting in a
reasonable estimate of fatigue life of the structure.
Beauvoir in filozofija

Published: August 2024

Simone de Beauvoir je bila že v času svojega življenja ugledna pisateljica, pripadnica pariškega filozofskega življenja in soustanoviteljica vplivne revije Les Temps modernes, v kateri je pred končno knjižno izdajo izhajal tudi njen Drugi spol. Njena slovita knjiga na presečišču filozofije in psihoanalize je pretresla stoletje, a je v filozofiji še vedno neznana in nepripoznana. Knjiga Beauvoir in filozofija je namenjena zapolnitvi vrzeli v zgodovini filozofskih raziskovanj, ki so se oplajala v Lacanovi vrnitvi k Freudu, in veliko filozofinjo umesti na križišče njenih filozofskih poti: s pomočjo Lévi-Straussove strukturalne analize sorodstva postavi pod vprašaj osnovni princip arbitrarnosti in s tem povezano sekundarnost Drugega, s pomočjo Althusserja osvetli pomen aleatoričnosti za materializem Simone de Beauvoir, na ozadju psihoanalize pa razišče moderno žensko dans tous ses états. V sklepnem poglavju knjiga odgovarja na vprašanje, kako s pomočjo Judith Butler in njene Antigone poiskati pot iz krize sorodstva prav v vrnitvi k Beauvoir, ki jo filozofiji nalaga današnji čas.

Authors: Mukaromah Kafifahdhi , Werdiningsih Wilis , Daryono Rihab Wit
Published: August 2024

Objective: Good infrastructure can help teachers in presenting learning materials better. Infrastructure can also assist principals in conducting school administration management more efficiently to focus on developing the quality of learning. This study aims to explore the role of infrastructure as a mediator of the influence of principal leadership and teacher competence on the quality of learning. Method: This study used a quantitative survey of randomly selected 42 teachers at SHS 1 Kawedanan Magetan. Data collection was carried out using a questionnaire consisting of a Likert scale with 5 points. PLS-SEM analysis is used to analyze data and test conceptual models. Data analysis techniques include statistical tests to test relationships and mediation. Results:  The results showed that the quality of learning was directly influenced insignificantly by the principal (β=-0.097; ρ=0.522) and teacher competence. Novelty: Infrastructure mediates significantly in improving the quality of learning. Schools and educational institutions must invest time and resources in training and professional development for teachers and principals in leadership, classroom management, and effective teaching methods. The overall quality of learning will improve when the principal can lead the school towards a clear vision of learning, and teachers have adequate skills and knowledge to plan, implement, and evaluate learning effectively.

Published: August 2024

Introduction. From an early age, patients with cerebral palsy (CP) require long-term, individual rehabilitation assistance to maintain impaired functions, develop self-service, social activity, and improve the quality of life (QOL). Changes in the QOL indices make it possible to adequately and timely determine the effectiveness of the ongoing medical rehabilitation in CP patients. Aim: to determine the effectiveness of short-term and long-term rehabilitation programs for CP patients.
Materials and methods. One hundred nine 5 to 18 years CP patients were examined. Of these, the 1st group consisted of 34 children who were rehabilitated under a long-term comprehensive program within the framework of the First Step project. The 2nd group consisted of 75 CP patients underwent a single rehabilitation course for 28 days. The comparison group consisted of 115 conditionally healthy children of the same age. The leading criterion for evaluating the effectiveness of rehabilitation programs was the quality of life in patients, determined by questioning the legal representatives of patients using the Russian version of the Health Utilities Index (HUI) questionnaire for children from 5 to 12 years old, as well as the Proxy version for over 12 years children by self-assessment (HUI23S2RU.15Q, Self-version).
Results. The total quality of life in CP patients was found to be low compared with conditionally healthy children in such aspects as speech, the ability to move, fine motor skills, and cognitive development. When analyzing the trend in multi-attribute utilita­rian indices (HUI3) of QOL in CP patients in the 1st and 2nd groups after 12 months. from the beginning of the first rehabilitation, significant positive changes in overall quality of life were determined in patients with cerebral palsy of the 1st group who received comprehensive rehabilitation compared with the level in patients of the 2nd group who underwent rehabilitation once. In CP patients from the 1st group, there was revealed a significant improvement in quality of life in the aspects of “Ability to move”, “Cognitive development” and “Pain”. The analysis of the cost-benefit data showed that the cost per 1 QALY in CP patients of the 2nd group rehabilitated under the short-term program is less. However, in patients with cerebral palsy from the 1st group, a higher usefulness (effectiveness) of a long-term rehabilitation program has been established.
Conclusion. A long-term comprehensive rehabilitation program for patients with cerebral palsy is effective and significantly improves the quality of life of sick children and their families.
Insufficient vaccination coverage in children with severe neurological pathology: causes and consequences
Authors: Galitskaya Marina G. , Abdullaeva Luizat M. , Makarova Svetlana G. , Fisenko Andrey P.
Published: August 2024

Children with chronic neurological pathology are at risk for the development of severe infectious diseases, but despite this, there is a poor coverage of preventive vaccinations in this category of children worldwide. For modern vaccine preparations, the presence of severe neurological conditions is not a contraindication to administration. There are only two reasons why vaccination should be postponed or the vaccine drug should be replaced. These are contraindications for the administration of live vaccines to children receiving immunosuppressive therapy, and contraindications for whole-cell pertussis vaccines to children with progressive neurological disease and convulsive syndrome. Studies conducted in different countries of the world prove the good tolerability and safety of vaccination in children with severe neurological pathology. But the use of certain drugs in the treatment of the underlying disease may affect the immunogenicity and effectiveness of vaccination. Currently, there is no generally accepted tactic for vaccinating children with various severe neurological conditions. This fact, as well as outdated attitudes in doctors and parents about the connection of vaccination with the onset of diseases of the nervous system, further increases the number of unvaccinated children. Issues related to the optimal vaccination time for children with severe neurological pathology, the frequency and strategy of vaccine administration still need to be addressed. There is a need to create widely recognized vaccination guidelines for children with severe neurological diseases, considering the nature of the disease, its course, and the therapy received.

Magnesium as a Biomaterial: Unlocking Innovations in Bone Regeneration and Healing: An Overview
Authors: p Sahla
Published: August 2024

Background: Dental implants may encounter failure at various stages, ranging from the osseointegration phase to the restorative phase within the oral cavity. The primary cause of dental implant failure is often attributed to the biological loss of bone integration with the implant surface. To address this issue, various strategies, such as dental implant surface coatings, modifications in implant biomaterials, etc. have been explored to mitigate the risk of implant failure. Emphasizing the significance of dental implant surface coatings, this review investigates the impact of Magnesium based coatings on cellular processes and their potential to enhance adhesion and osseointegration.

Objective: To review related literature covering different aspects of Magnesium based biomaterials and its applications in oral and maxillofacial rehabilitation.

Materials and methods: Electronic search was performed in PubMed, Scopus and Ovid to identify scientific studies and review articles that investigated Magnesium based implant biomaterial. The search included all articles published in English language in peer reviewed journals in the period from 2011 to 2024. The search followed a specific strategy which included combination of the following keywords: Magnesium, Implant Biomaterial, Titanium Magnesium composite, Corrosion and degradation, Magnesium-Hydroxyapetite, biocompatibility

Conclusion: Literature searches have shown that magnesium exhibits remarkable properties such as, biocompatibility, osteogenic potential, favourable soft tissue response and mechanical strength, suggesting that it is an excellent biomaterial for dental implants. Magnesium has various applications in clinical scenarios like maxillary sinus lifting surgery and alveolar socket preservation. Meanwhile, there are studies that highlight its drawbacks, such as biodegradation and corrosion. It was also found that most of the studies on Magnesium dental implants are short-term studies and there is a need for more long-term clinical trials to prove that Magnesium is worth enough to replace titanium as a biomaterial in dental implantology.

Introduction: Hepatoblastoma is the most common liver malignancy in children. Hepatoblastoma in infants is rare and usually presents as an abdominal mass without specific symptoms. Diagnosis is difficult, supported by adequate imaging modalities, liver biopsy, and hepatoblastoma marker testing. Case Presentation: A 3-month-old boy presented with a chief complaint of abdominal mass 3 days after birth without any other complaints. Nutritional status was normal. Vital signs were stable. Physical examination revealed anemic conjunctiva, hepatomegaly, and a palpable lump in the right upper quadrant of the abdomen. The laboratory results were Hb 8.2 g/dL, AST 45 U/l, ALT 13 U/L, gamma-GT 218.2 U/L, alkaline phosphatase 200 U/L, total bilirubin 3.00 mg/dL, direct bilirubin 1.40 mg/dL, Rubella IgG Reactive (20.60 IU/mL), CMV IgG Reactive (145.1 AU/mL), LDH 404 U/L, and Alpha-fetoprotein 5720.45 ng/mL. Abdominal ultrasound was consistent with a malignant liver mass, possibly hepatoblastoma, with a heteroechoic mass +/- 6.57 x 7.21 x 6.76 cm in the right and left liver lobes. A computed tomography scan of the abdomen confirmed the hepatoblastoma in segments V, VI, VII, and VIII of the right lobes with hepatomegaly. Conclusion: The possibility of hepatoblastoma should be considered when an infant presents with a complaint of an abdominal mass without specific symptoms. In children younger than 2 years, radiologic confirmation of hepatoblastoma is sufficiently accurate, especially when supported by elevated AFP in facilities with limited liver biopsies

This study investigates the impact of institutional quality on external debt management in Nigeria, focusing on the period from 1980 to 2022. It employed data from the World Development Indicator and the CBN Statistical Bulletin, the research employed descriptive statistics, trend analysis, and advanced econometric techniques, including the Augmented Diceey-Fuller (ADF) unit root test and the Auto Regressive Distributed Lag (ARDL) model, to explore the relationships among eey variables. The dependent variable, Debt to Gross Domestic Product (GDP) ratio (DGDP), is analyzed against several independent variables: government transparency index (GTI), government effectiveness index (GEI), corruption perception index (CPI), regulatory quality index (RQI), inflation rate (INF), and the logarithm of government expenditure (LINGEXP). The findings reveal that higher government transparency and reduced corruption are associated with lower debt-to-GDP ratios, while government effectiveness and regulatory quality are positively correlated with higher debt levels. Inflation and government expenditure also significantly impact debt dynamics, underscoring the need for effective inflation control and prudent fiscal management. The ARDL bounds test confirms a long-term relationship between institutional quality and external debt management, highlighting the importance of stable and transparent institutions for sustainable debt practices. The study concludes that enhancing institutional quality through improved transparency, accountability, and regulatory framewores, along with effective inflation control and fiscal management, is crucial for Nigeria's economic stability and sustainable debt management.
Examining the Business Growth Challenges and Prospects of Small and Medium Enterprises (SMEs): A Case Study of Garden Township Metal Fabricators, Lusaka

Published: August 2024

The study was aimed at examining the business growth challenges and prospects of small and medium enterprises (SMEs) with a particular focus on metal fabricators in Garden Township, Lusaka, Zambia. In doing so, specific focus on how these businesses align with Dynamic Capabilities, and Innovation and Entrepreneurship Theories was highlighted. The research employed a qualitative approach, combining primary and secondary data collection. Primary data was gathered through in-depth interviews with 15 participants and five focus group discussions, each comprising two business owners and three welders. Secondary data was obtained from existing literature, industry reports, and academic studies. The primary objectives were to identify the major challenges hindering business growth among metal fabricators, to explore potential strategies for overcoming these challenges, and to assess awareness and accessibility of government support initiatives. Key findings revealed that financial constraints, lack of strategic knowledge, outdated technology, unreliable infrastructure, and insufficient government support are the main barriers to growth. Participants unanimously called for government intervention, emphasizing the need for easier access to loans, financial management training, modern equipment, and strategic planning workshops. The study highlighted that while government initiatives like the Citizen Economic Empowerment Commission (CEEC) and Constituency Development Fund (CDF) are recognized, practical barriers prevent SMEs from accessing these resources. This gap underscores the necessity for more effective implementation and outreach to ensure SMEs can benefit from available support. Recommendations include simplifying access to financial resources, providing strategic business education, implementing targeted support programs for the metal fabrication industry, and improving infrastructure. Future research should focus on evaluating the impact of training programs, streamlined loan processes, technology adoption, and government policy effectiveness on SME growth. Addressing these challenges through a holistic approach can enhance the dynamic capabilities and innovation strategies of metal fabricators, fostering sustainable business growth and competitiveness.

Shark and ray populations continue to decline in many regions around the world. The contribution of artisanal fisheries to these declines remains poorly understood for many locations. A rapid assessment framework using fisheries-independent sampling and fisher interviews was employed to study elasmobranch occurrence and use in coastal artisanal fisheries of Guadeloupe, Martinique, and Tobago. In-person interviews (n = 405) were conducted between June 2015-June 2017, and baited remote underwater video stations (BRUVS) (n = 50 video drops/reef) were deployed in nine reefs across the islands. The fate of elasmobranchs caught by artisanal fishers varied by island. Martinique reported the highest proportion of fishers keeping their catch for subsistence among the study locations. In Guadeloupe, fishers most frequently sold their catch, and Tobago fishers engaged in both subsistence fishing and sale. Fishers retained almost all animals caught and reported reduced catches of elasmobranch compared to when they started fishing. BRUVS revealed relatively low elasmobranch occurrence and a low Shannon diversity index compared to Caribbean nations with less fishing pressures on elasmobranchs. The present study highlights the need for improved data on, and monitoring of, artisanal fisheries.

Limestone mining threatens endangered frog endemic to a tropical karst in the Southeastern Brazil
Authors:   , Silva Pedro Augusto da Rocha
Published: August 2024

The frog Ischnocnema karst is endemic to a tropical karst in southeast Brazil, where limestone exploration is continuously increasing. Here we describe the species habitat, range and threats from mining activities. The species is strictly associated to limestone outcrops surrounded by caves and seasonally-dry tropical forests. Extent of Occurrence was 530.4 km2, while Area of Occupancy of the species covers 126 km2 and Potential Distribution was 163.6 km2. Even though different methods presented a spatial variation, they were consonant in restrict I. karst to the limestone outcrops of studied region. Mining influences directly 33% of species predicted distribution, while 79.8% is under indirect impact. Only 3% of this predicted distribution is under protected areas. I. karst is a narrowly endemic frog species under high pressure of limestone exploitation. Species is considered Endangered based on its fragmented geographical range and habitat loss. Strengthen protected areas coverage and build an action plan is urgent to ensure species conservation. Keywords: threatened species; species distribution model; limestone karst; mining impact.
