Published: February 2024

Brassica oleracea L. var. capitata f. alba (Brassicaceae) is a nutrient rich leafy-headed cruciferous vegetable. The bioactivities of the various extracts such as aqueous, hexane, chloroform and methanol of this Indian cultivated vegetable have been investigated. The anticancer activity was tested in the specific cell lines (MCF-7, HCT116 and 3T3L1). The methanol and aqueous extracts showed the highest cytotoxicity found in the MCF7 cell line. The chloroform extract showed antibacterial activity against Gram-negative Escherichia coli, but not against Gram-positive Bacillus subtilis. The aqueous extract of the sample gives maximum antioxidant activity. The qualitative and quantitative analyses of these extracts were carried out and confirmed the presence of indole-3-carbinol in the methanol extract. The significant differentially expressed genes that involved in the treatment of indole-3-carbinol on MCF7 cell line have been identified from the GEO dataset analysis. This study strongly proves the correlation between the anticancer, antibacterial and antioxidant activities of the sample and the presence of the specific chemical compound indole-3-carbinol and its metabolic involvement in the human diet and digestive system.

The medicinal herb Nigella sativa Linn of the Ranunculaceae family is widely used everywhere in the world. In the past, numerous illnesses and disorders have been treated with N. sativa L. seeds. Both in vivo and in vitro analyses revealed that N. sativa L., possesses numerous neuroprotective effects. The methanolic extract of N. sativa L. was evaluated for the presence of antioxidant and anticholinesterase activity and the findings revealed that the extract has outstanding antioxidant and anticholinesterase activity. Since the extract was found to possess excellent activity, the methanolic extract was separated using column chromatography with the aid of bioactive guided fractionation. A total of 19 fractions were collected and analyzed for antioxidant potential. The active fractions were collected, pooled and analyzed using LC-MS techniques. The outcomes revealed the existence of Kaempferol 3-(2-galloyl-alpha-L-arabinopyranoside). To assess the safety aspects of methanolic extract, a subacute toxicity test was performed using zebrafish. The results of the liver function test and histoarchitecture analysis found that there were no adverse consequences from the extract. Altogether, these results suggest that N. sativa L., could be a promising therapeutic drug against Alzheimer’s disease.

Published: February 2024

Wild fruit fly larvae can be distinguished at the family level such as Drosophilidae and Tephritidae larvae are based on size or spiracles arrangement, but such visual distinction is more intricate between Drosophilid species. In the present study, to identify the Drosophila immigrans and Drosophila suzukii species at the larval stage, we employed a simple, rapid PCR-RFLP experiment. Wild suspected larvae from Drosophila immigrans and Drosophila suzukii species were collected from 3 different geographical regions. DNA was isolated and a PCR-RFLP profile was developed using the XmnI restriction enzyme. Sequencing of the mitochondrial COI gene from larvae was performed to evaluate the species. PCR-RFLP analysis from Drosophila suzukii wild larvae generated three distinct bands with 120bp, 210bp and 250bp. Similarly, Drosophila immigrans generated 2 distinct bands with 270bp and 310bp. Restriction digestion products from both the larvae and adult flies were the same, hence the accuracy of the PCR-RFLP profile developed from both suspected wild larvae and adult flies was 100%. Sequencing analysis confirms that wild field collected larvae belong to Drosophila suzukii and Drosophila immigrans. Present study clearly shows that PCR‐RFLP is a fast, simple, inexpensive and accurate molecular method and it can be successfully used for species identification at the early stages of the life cycle of Drosophila species.

Published: February 2024

The most common cause of nosocomial infection worldwide is caused by Gram-positive coccus bacteria or what we commonly call Methicillin-resistant Staphylococcus aureus (MRSA). This study aimed to find novel antimicrobial agents from the banyan tree (Ficus benjamina L.) hanging roots to treat MRSA. Docking experiment and well diffusion were used as in silico and in vitro experiments respectively to identify the potential of stigmasterol against MRSA. The data were analyzed statistically with one-way variance analysis (ANOVA), post-doc Tukey assay, correlation, and regression by SPSS Amos 24. In the in silico experiment, stigmasterol was strongly associated with penicillin-binding protein 2a (PBP2a) on the active side of LYS289. Thus, it had the potential to inhibit PBP2a. Disruption of cell walls, the release of cytoplasmic contents, and a decrease in the cellular volume of MRSA were caused by the inhibition of PBP2a. The well diffusion test results showed the inhibition zone in 50 - 100 μg/ml of stigmasterol against MRSA. The inhibition zone was in the range of 7.38 – 10.17 mm. The inhibition diameter indicated a significant difference with a p-value < 0.05. The results of statistical analyses indicate that stigmasterol is effective as an antimicrobial against MRSA. Stigmasterol has potential as a potential microbial agent for the therapy of MRSA.

Authors: Philip Indhu , Sarojini Suma , Biswas Soma , Jayaram Saranya
Published: February 2024

The use of heavy metal resistant plant growth promoting endophytes is an effective method for improving crop yield and cleaning up contaminated sites. In our study, we have isolated thirteen bacterial endophytes from the shoots of Alternanthera philoxeroides, an aquatic plant from Bellandur lake, Bangalore, India. Among the isolates, Bacillus paramycoides showed significant plant growth promotion properties including an extortionate amount of indole acetic acid (IAA) production (144.69 ± 1.01 μg/mL) along with other plant growth promoting attributes like ammonia production, nitrogen fixation, phosphate, potassium solubilization, 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase and siderophore production. The isolate also demonstrated the ability to resist pathogen attacks by producing extracellular enzymes, which could have potential industrial uses. Furthermore, it displayed resistance to multiple heavy metals like chromium (Cr), copper (Cu), lead (Pb), zinc (Zn) and cadmium (Cd) as well as the ability to tolerate high salt concentrations (up to 7% NaCl). These characteristics make it an ideal candidate for promoting plant growth in stressful environments and as an effective bioremediation agent.

Published: February 2024

In this study, the rhizospheric soil of wild sugarcane from three different salt-affected soils of the eastern Indo-Gangetic Plains was sampled. Rhizospheric bacteria from S. spontaneum were isolated and they were characterized for growth-promoting traits with molecular identification. A total of 49 isolates were isolated from three S. spontaneum rhizosphere soils from different places. These isolates were shown to have differential tolerance to NaCl concentrations up to 2000 mM. Owing to their host habitat and poor nutrient availability, these bacteria were found to have excellent tolerance to high NaCl concentrations along with having multiple plant growth traits. Apart from salt tolerance, these isolates were screened for EPS production, phosphate solubilization, zinc solubilization, siderophore production and ammonia production and based on multiple plant growth-promoting traits, twenty isolates were taken for molecular identification and further in vivo screening. These twenty S. spontaneum rhizospheric microbes belonged to the classes Gammaproteobacteria, Firmicutes (Bacilli) and Actinomycetia, representing six genera and 15 species. In vivo growth promotion studies indicated that some of these isolates could improve germination and growth in rice seedlings. The results of this study signify the possibility of utilizing wild crop microbiomes to nurture cultivated crops under adverse growing conditions.

Perubahan garis pantai merupakan suatu proses yang menunjukkan adanya perubahan luas lahan di pantai yang dapat disebabkan oleh berbagai faktor seperti faktor alami dan faktor manusia. Satu diantara faktor alami yang dapat menimbulkan perubahan garis pantai adalah abrasi. Abrasi akibat gelombang besar dapat mengikis garis pantai sehingga mengalami degradasi. Seperti yang terjadi di Pantai KuraKura. Pantai Kura-Kura terletak di Kabupaten Bengkayang, Provinsi Kalimantan Barat. Garis pantai di Pantai Kura-Kura terus mengalami perubahan pada setiap tahun. Perubahan yang terjadi menyebabkan penyempitan luas pantai serta kerusakan daerah konservasi. Hal ini tentu berdampak negatif dan menghambat Pantai Kura-Kura untuk menjadi ekowisata bahari yang berkelanjutan. Oleh karena itu, perlu adanya upaya konservasi yang tepat untuk meminimalisir dampak perubahan garis pantai akibat abrasi di Pantai Kura-Kura.

Published: February 2024

Let $G$ be a graph. Then a subset $C$ of vertices of $G$ is called a vertex cover hop dominating if $C$ is both a vertex cover and a hop dominating of $G$. The vertex cover hop domination number of $G$, denoted by $\gamma_{vch}(G)$, is the minimum cardinality among all vertex cover hop dominating sets in $G$. In this paper, we initiate the study of vertex cover hop domination in a graph and we determine its relations with other parameters in graph theory. We characterize the vertex cover hop dominating sets in some special graphs, join, and corona of two graphs and we finally obtain the exact values or bounds of the parameters of these graphs.

Published: February 2024

Hepatitis is a viral infection that can cause inflammation of the liver and lead to severe liver damage and even death. The study of hepatitis in Burkina Faso is crucial for several reasons. Indeed, understanding the epidemiology of hepatitis in Burkina Faso can help develop effective prevention and control strategies, and its study can contribute to a better understanding of the global burden of the disease and the development of effective interventions in other parts of the world. To this aim, a new differential susceptibility and infectivity mathematical model of Hepatitis B transmission was developed in order to simulate the potential spread of the Hepatitis B virus in the population of Burkina Faso. Once the mathematical model is presented, the existence and uniqueness of non-negative solutions are proved. The model has a globally asymptotically stable disease-free equilibrium when the basic reproduction number R01 and a globally asymptotically stable endemic equilibrium when R0 > 1. The global asymptotic stability of the disease-free equilibrium has been studied using the Castillo Chavez method [5]. The Lyapunov function and the LaSalle invariance principle are used to prove the global asymptotic stability of the endemic equilibrium [26, 4, 18]. To simulate the proposed model, a Matlab numerical code has been developed. Numerical simulations are performed using data of Burkina Faso. The obtained numerical results confirm analytical results as well as the evolution of hepatitis B in Burkina Faso.

Published: February 2024

Bayesian estimation of the linear regression parameter system is considered by deploying Median Rank Set Sampling (MRSS). The full conditional distributions and the associated posterior distribution are obtained. Therefore, based on Markov Chain Monte Carlo simulation, the Bayesian point estimates and credible intervals for the regression parameters are determined. To measure the efficiency of the obtained Bayesian estimates concerning the frequentist estimates we compute the asymptotic relative efficiency of the obtained Bayesian estimates using Markov Chain Monte Carlo simulation.

Published: February 2024

Consider G a simple connected graph. In this paper, we introduce the Universal distance matrix UD (G). For α, β, γ, δ ∈ R and β ̸= 0, the universal distance matrix UD (G) is defined asUD (G) = αTr (G) + βD(G) + γJ + δI,where Tr (G) is the diagonal matrix whose elements are the vertex transmissions, and D(G) is the distance matrix of G. Here J is the all-ones matrix, and I is the identity matrix. In this paper, we obtain the universal distance spectra of regular graph, join of two regular graphs, joined union of three regular graphs, generalized joined union of n disjoint graphs with one arbitrary graph H. As a consequence, we obtain the eigenvalues of distance matrix, distance Laplacian matrix, distance signless Laplacian matrix, generalized distance matrix, distance Seidal matrix and distance matrices of complementary graphs.

Let G be a graph. Then B ⊆ V (G) is called a certified hop independent set of G if for every a, b ∈ B, dG(a, b) ̸= 2 and for every x ∈ B has either zero or at least two neighbors in V (G) \ B. The maximum cardinality among all certified hop independent sets in G, denoted by αch(G), is called the certified hop independence number of G. In this paper, we initiate the study of certified hop independence in graphs and we establish some of its properties. We give realization results involving hop independence and certified hop independence parameters, and we show that the difference between these two parameters can be made arbitrarily large. We characterize certified hop independent sets in some graphs and we use these results to obtain the exact values or bounds of the parameter. Moreover, we show that the certified hop independence and independence parameters are incomparable.

A presente dissertação apresenta os resultados de uma pesquisa que se vincula à área de saúde mental e que tem como objeto de estudo o CAPS do sudeste do Brasil e os adolescentes usuários da substância psicoativa cannabis. O objetivo geral foi analisar a acurácia do rastreio psicopatológico da psicose em adolescentes usuários de substância cannabis no CAPS do sudeste do Brasil. A pesquisa traz o diálogo com teóricos e a percepção da práxis do psiquiatra clínico, no papel de pesquisador, que atuou nos serviços de saúde mental no CAPS/AD na cidade de Governador Valadares MG durante o período de janeiro 2012 a março/ 2018. E dentro do escopo da pesquisa qualitativa trazemos os técnicos especialistas dentro do CAPS para uma análise sobre a acurácia do rastreio realizado em adolescentes usuários de substância psicoativa cannabis. O agrupamento do conteúdo do referencial teórico pormenorizado se deu em todo o curso da pesquisa, a análise da revisão da literatura científica permitiu uma investigação e um aprofundamento sobre a detecção precoce de psicose subclínica em adolescentes usuários de substância psicoativa cannabis, o delineamento da pesquisa considerou a substância cannabis e tendo como sujeitos de pesquisa os adolescentes no surgimento do quadro psicótico com relação ao uso dessa substância mais propriamente. As respostas indicam o desconhecimento por parte da equipe sobre o sujeito da pesquisa, adolescentes em atendimento no CAPS, principalmente no que tange a psicose em adolescentes usuários de cannabis. Desta forma, a resposta ao problema levantado nos deixa com uma lacuna no processo de atendimento e nos instiga a dar continuidade ao estudo para que possamos aplicar instrumentos de rastreio de psicose e permita sair do senso comum dos critérios para diagnóstico e tratamento e nos faça avançar científicos e sistematizados dentro dos CAPS.
Fordismo y postfordismo. Control social y educación

This text is part of the research process that was carried out for the Master's Thesis in Higher Education at the Santiago de Cali University, entitled Specific Contributions of Virtual Environments in the Teaching-LearningProcesses in University Settings. It was intended to establish an overview of the current context in which the University operates as an institution, and the global trends that economic models involve as part of educationalprocesses. As a documentary research, a bibliographic review of different authors in pedagogy was made, in order to carry out an analysis of the articulations between these forms of work organization, the changes in the predominant pedagogical models in society during different times, and the current situation of the quality ofhigher education in Colombia. As a central idea, it was found that the apparent overcoming of pedagogical modelsbased on a Fordist-behaviorist concept of education, beyond signifying an evolution in training processes,became a way of reorganizing university models to train better adapted professionals to the new post-Fordist-neo-Fordist industrial systems, and less interested in proposing social changes or reflections on fairer, more humane economic-industrial models.

The aim of this study was to investigate the exposure of the insecticide carbofuran on the necrosis of protoplasmic astrocyte cells in the cerebrum of mice (Mus musculus). Twenty mice were divided into four groups with five replicates each. The control group (P0) received 0.5% physiological NaCl, P1 (carbofuran 0.0833 mg/kg BW), P2 (carbofuran 0.0417 mg/kg BW), P3 (carbofuran 0.0208 mg/kg BW), and carbofuran was administered for ten days. On the 12th day, brain necropsy and HE staining were performed to observe the necrosis of protoplasmic astrocyte cells in the mice cerebrum. The necrosis of protoplasmic astrocyte cells was analyzed using ANOVA followed by Duncan's test. The results showed that carbofuran caused necrosis of protoplasmic astrocyte cells (p < 0.05), and the necrosis increased with increasing carbofuran dosage (p < 0.05).

Orthodontic treatment commonly induces pain in a significant majority of patients, ranging from ninety to ninety-five percent. This study aimed to systematically review and assess the intensity of orthodontic pain associated with fixed appliances. A comprehensive search was conducted on Pubmed and Hinari databases, as well as orthodontic journal sites, spanning from March to May 2021. Articles reporting on pain intensity in individuals undergoing labial fixed orthodontic treatment were meticulously selected using specific keywords. The Visual Analog Scale was employed to evaluate pain intensity, and each included article underwent a rigorous evaluation based on essential criteria for scientific writing. Data compilation and analysis were performed using SPSS software. The findings revealed a mean pain intensity of 20.2 mm ± 15.8 across the general study population, with a minimum intensity of 0.2 mm and a maximum of 63.2 mm. Effective communication by practitioners, preemptively addressing and explaining the anticipated discomfort and pain during treatment, results in a reduced need for analgesics.
