Utilización de humus de lombriz roja californiana (Eisenia foetida Saligny, 1826) en la alimentación de gallinas ponedoras
Authors: Suárez Cardoso Derly Tatiana , Ríos Cruz Karen Lorena , Peñuela Sierra Lina María , Castañeda Serrano Román David
Published: November 2022

El objetivo de este trabajo fue evaluar los efectos de la substitución de concentrado comercial por niveles de humus de lombriz roja californiana (lombricompuesto), sobre los parámetros productivos, la calidad del huevo y la viabilidad económica. Se utilizaron 120 gallinas ponedoras de la línea Hy- line W-36 de 90 semanas de edad, que fueron distribuidas en un diseño completamente al azar con 4 tratamientos y 10 repeticiones de 3 aves en cada unidad experimental. Los tratamientos consistieron en la substitución del concentrado comercial por niveles de lombricompuesto, de la siguiente manera: T1: 100% concentrado; T2: 90% concentrado y 10% lombricompuesto; T3: 80% de concentrado y 20% de lombricompuesto: y T4: 70% de concentrado y 30% de lombricompuesto. Se evaluaron los parámetros, la calidad de huevo y análisis económico. Los resultados obtenidos para parámetros productivos en las aves no muestran diferencias (P>0,5). Los indicadores de calidad del huevo mostraron diferencias (P<0,05) en el color de la yema y grosor de la cáscara; a medida que aumentó la substitución del concentrado por el lombricompuesto, los demás parámetros de calidad de huevo evaluados no fueron alterados. Se concluyó que la inclusión de niveles de sustitución de concentrado comercial por lombricompuesto no altera los parámetros productivos en gallinas ponedoras de la línea Hy Line W-36 con 90 semanas de edad. Sin embargo, el color de la yema del huevo y el espesor de la cáscara disminuyeron a medida que aumenta el nivel de lombricompuesto en la dieta. Por otro lado, la utilización de lombricompuesto en dietas para gallinas ponedoras disminuye los costos de producción hasta en un 20%.De esta manera, el lombricompuesto surge como una alternativa alimenticia para disminuir los costos de producción para pequeños avicultores.
Extensión de presencia y área de ocupación de la nutria neotropical (Lontra longicaudis) en la cuenca del río La Vieja, alto Cauca, Colombia
Authors: Botero Botero Álvaro , Correa Viana Martín , Torres Mejía Ana María , Utrera Antonio , Kattan Gustavo
Published: November 2022

Desde agosto de 2006 hasta agosto de 2007 evaluamos la distribución de la nutria neotropical en la cuenca alta y media del río La Vieja; determinamos su extensión de presencia por medio de encuestas y el área de ocupación actual mediante visitas a campo. Décadas atrás la nutria presentaba una distribución continua en todos los ríos de la cuenca desde 950 m hasta 2432 msnm, con un área de extensión de presencia de 4895 ha; actualmente la nutria presenta distribución continua sólo en el cauce principal del río La Vieja y su población se ha fragmentado en los ríos Quindío, Barragán, Espejo, Roble y Barbas, con un área de ocupación de 2569 ha, lo que corresponde a 52,5% del área de su extensión de presencia original. También se presenta una disminución de su distribución altitudinal de 901 m. Tal disminución se debe probablemente a la reducción del hábitat por factores antrópicos tales como contaminación de los cauces, tala de bosques ribereños, minería de material de arrastre, pesca con dinamita y barbasco.

Dieta de aves migratorias en un sistema agroecológico del Valle del Cauca, Colombia
Authors: Hurtado Giraldo Alejandra , Cruz Bernate Lorena , Molina Enrique José
Published: November 2022

Aunque cerca de 10% de la diversidad de aves en Colombia está representada por avifauna migratoria transcontinental, aún se desconocen muchos aspectos ecológicos importantes para su conservación. El presente trabajo investigó la dieta de aves migratorias y la oferta de artrópodos en la Reserva Natural El Hatico, un agroecosistema en el departamento del Valle del Cauca, suroccidente de Colombia. Se hicieron censos visuales y capturas con redes de niebla. A cada ave capturada se le suministró por vía oral solución salina al 1% para obtener muestras de excrementos, en las cuales los restos de insectos fueron identificados, cuantificados y analizados. La disponibilidad de artrópodos se estableció mediante muestreos y se elaboró una colección de referencia. La dieta de cinco especies migratorias capturadas fue similar y estuvo constituida principalmente por Coleoptera, Hymenoptera y Araneae, mientras que los órdenes más abundantes en el muestreo del agroecosistema fueron Diptera, Hemiptera y Coleoptera. Se sugiere que las especies que llegan a la reserva natural presentan sobreuso de ciertas presas en su alimentación, dirigida principalmente hacia artrópodos, y posiblemente condicionada por la capacidad de hallazgo de los ítems y las estrategias de búsqueda de alimento de las especies.

La revolución filosófica de Kuhn
Authors: G. Laguna Humberto , Miramontes Pedro , Cocho Germinal
Published: November 2022

En este artículo postulamos que el trabajo de Kuhn es una revolución filosófica para la filosofía de la ciencia. La búsqueda de revoluciones filosóficas es una extensión de las ideas de Kuhn acerca de las revoluciones científicas. Las revoluciones filosóficas se distinguen de las revoluciones científicas en algunos aspectos que discutimos en este trabajo. Defendemos que la revolución kuhniana consiste en la naturalización de la filosofía de la ciencia que se desprende de sus trabajos y discutimos la analogía biológica que Kuhn empleó como un ejemplo ilustrativo.
La plausibilidad conceptual del dualismo mente-cuerpo. Una nueva defensa del argumento modal
Authors: Guirado Matías Alejandro
Published: November 2022

La principal objeción contra al dualismo cartesiano en filosofía de la mente es que resulta incompatible con la ciencia. Se sostiene, en particular, que el principio de clausura causal del mundo físico y el teorema de preservación de la energía, así como el concepto de interacción dinámica de la física fundamental, desautorizan la postulación de interacciones causales entre sustancias pensantes y sustancias extensas. En este trabajo sostengo que esta conclusión es por lo menos apresurada y que no es un asunto trivial refutar el dualismo cartesiano usando consideraciones empíricas. Mis tesis son: (i) que las críticas antidualistas basadas en premisas científicas colapsan en un reduccionismo metafísicamente implausible y (ii) que la teoría física no excluye la existencia de una relación de causación o interacción dinámica recurrente como la que se requiere para explicar la experiencia consciente, postulando un nexo pertinente entre mentes inmateriales y sistemas nerviosos.

Me complace presentar a la comunidad académica nacional e internacional el fascículo 29 de la revista Discusiones Filosóficas. Como seguramente es conocido por la mayor parte de los lectores, el sistema de indización de revistas colombiano está experimentando una radical transformación, cuyas consecuencias, entre otros aspectos, afectan notablemente el futuro de las ublicaciones científicas periódicas en el área de las humanidades y las ciencias sociales. En efecto, COLCIENCIAS, sin tomar en cuenta la opinión de los editores de revistas colombianos, ni a de la mayor parte de las universidades del país ha decidido hacer de indicadores como los informes de ciertas bases de datos pagas (ISI Web of Science, Scopus) sobre la ubicación de una revista en sus distintos cuartiles, la principal razón para determinar su categoría. Aunque semejante proceder echa por la borda un trabajo sostenido de más de 20 años, COLCIENCIAS sigue haciendo oídos sordos a los planteamientos de los académicos. Debido a dicha contingencia, este podría ser el último número de la revista que aparece en la categoría A2, para alcanzar la cual trabajamos incansablemente durante todos estos años cumpliendo al pie de la letra los requisitos establecidos. Resulta aventurado predecir lo que pueda ocurrir con la inestable política de COLCIENCIAS y su efecto sobre las revistas colombianas, así como con el destino de nuestra publicación. Confiamos en que, finalmente, dicha entidad acceda a escuchar a los editores, autores, académicos e instituciones universitarias y logre concertar una política más acorde con las realidades del país y, sobre todo, más ajustada a las especificidades de las revistas dedicadas a la filosofía o las humanidades.
La posición de John Stuart Mill en relación al problema de Hume: la justificación de la inferencia inductiva y la naturaleza del principio de inducción
Authors: León Miranda Ana Pía
Published: November 2022

El presente artículo tiene como objetivo analizar y reconstruir la postura de John Stuart Mill respecto del problema de la inducción. Mostraremos que Mill si bien conoció las objeciones de Hume, no se refiere a ellas en gran medida porque para él la justificación de la inducción es posible. La hipótesis principal será probada por medio de dos tesis: la primera, alude a la evasión de la argumentación circular respecto de la justificación de la inferencia inductiva; y la segunda, refiere al tipo de inducciones que fundamentan el principio de regularidad: inducciones por enumeración simple.

Una propuesta de análisis cinematográfico integral
Authors: Aristizábal Santa Johnnier , Pinilla Rodríguez Óscar
Published: November 2022

El presente artículo reflexiona sobre una metodología de análisis cinematográfico integral para aproximarse al cine desde su funcionamiento formal, estético y semiótico. Para ello aborda la perspectiva analítica de los componentes del cine reseñados por Lauro Zavala y los planteamientos acerca de los oficios propuestos por Michel Chion como eje de categorización mediante el cual se aplican diversos conceptos provenientes de la teoría del cine para describir y analizar una película de ficción. A partir de lo anterior se proponen estrategias de interpretación desde las cuales sea posible integrar perspectivas de otras disciplinas sin descuidar la película cinematográfica en sí, buscando proponer una salida a la dicotomía entre análisis interpretativo y análisis ilustrativo planteada por Lauro Zavala. Esta metodología se estructura como una alternativa para construir conocimiento sobre el cine en sus diversas áreas donde prime el estudio de las películas y el desarrollo del conocimiento cinematográfico en su práctica, técnica y teoría.
Manuel Ancízar y la edición de Peregrinación de Alpha. Nuevos presupuestos para el registro de iniciales de la cultura de diseño en Colombia
Authors: Parra Castro Juan Fernando
Published: November 2022

En la búsqueda de nuevas alternativas para la reconstrucción histórica del diseño en Colombia el siglo XIX ha sido poco explorado a pesar de sus importantes aportes a la construcción de la nacionalidad colombiana. El artículo desarrolla un capítulo de la evolución de la cultura editorial colombiana poco explorado por la historiografía del diseño a partir del esbozo del imaginario material con que Manuel Ancízar (1811-1882) en su libro Peregrinación de Alpha (1853) incitó una ruptura en el panorama cultural colombiano. El método empleado para el desarrollo teórico del imaginario y sus implicaciones históricas fue concebido en el marco de una investigación mayor y alterna consideraciones en torno al problema de la cultura material, los estudios bibliográficos y la teoría del diseño para confirmar en un primer apartado la cercanía de Ancízar con la tecnificación de los procesos artísticos en que se amparó inicialmente la impresión local. Peregrinación fue el segundo libro del intelectual publicado en la Nueva Granada y de los primeros libros de renombre a nivel nacional que publicó la Imprenta de Echeverría Hermanos, objeto de desarrollo del segundo apartado y que fue establecida después de 1851 por los artistas venezolanos convocados por Ancízar para operar los talleres de la imprenta que pretendió establecer el gobierno de Tomás Cipriano de Mosquera (1849-1853). A continuación se desarrolla un breve análisis tipográfico del libro, que como obra editorial corresponde a una serie de consideraciones planteadas en los dos primeros apartados, entre ellas, la introducción de hábitos modernos de edición, impresión y manejo de empresas editoriales; la construcción de un público letrado a escala nacional y en medio de todo este proceso, la formalización de unas bases institucionales para la gestación de prácticas afines al diseño a mediados del siglo XIX.

Published: November 2022

The purpose of this research is to determine the effect of digital stories on the listening comprehension skills of primary school 4th grade students. For this purpose, the research has carried out with a quasi-experimental design with pre-test post-test control group. The sample of the research consisted of 52 students studying in two different 4th grade branches of a public primary school in the second semester of the 2018-2019 academic year. The stories transferred to digital in the research have selected from the texts in 3 different Turkish textbooks at the 4th grade level of primary school published by the Ministry of National Education and taught to students in previous years. 8 narrative texts from the themes of "My Beautiful Country Turkey" and "Production, Consumption and Efficiency" in the textbooks have converted into digital through digital design programs. During the implementation process, the animations of 8 stories transferred to digital have watched by the students in the experimental group, and the students in the control group have read and listened to the same story texts by the teacher. The Listening Comprehension Test has used to determine the listening comprehension achievement scores of the students in the experimental and control groups at the beginning and end of the application process. As a result of the research, it has determined that there was a significant difference between the pre-test and post-test achievement scores of the students in the experimental group, where the stories have played digitally.

Authors:   The Pharmaceutical Society Of Korea, Park Ji Eun , Oh Mi Hyune
Published: November 2022

The Ministry of Food and Drug Safety is amending its test methods for dietary supplements (functional health food) to establish regulatory standards and specifications in Korea. In this regard, we continue to research analytical method development for the items to improve their sensitivity and selectivity. In this study, we have developed liquid chromatographic-tandem mass spectrometry for astaxanthin analysis. This method can be used to characterize and quantify dietary supplement formulations containing astaxanthin. The procedure was validated at 37.5-2,400 ng/mL. Standard calibration curves presented linearity with the coefficient of determination (r²)>0.999. The limits of detection and limits of quantitation were 16 and 49 ng/mL, respectively. The recovery results ranged between 91.9-97.4% at three different concentration levels with relative standard deviations (RSDs) of less than 3.6%. The precision results (RSDs) were obtained between 1.2-3.5%, and reproducibility (1.8%) was obtained. These are in accordance with the established validation criteria (Association of Official Analytical Chemists). Our research can provide scientific evidence to amend the astaxanthin test method for Health Functional Food Codes.
Phylogenetic classification of bacterial populations using a combined analysis of core SNPs and the presence/absence of accessory genes v1
Authors: Johnson Jared
Published: November 2022

Whole genome sequencing-based typing methods have become the gold standard for phylogenetic classifications of bacterial populations. The most common approach is to compare single nucleotide polymorphisms (SNPs) across the core genome of a cohort of isolates. Greater confidence in SNP-based population assignments can be gained by extending this analysis to include the accessory genome. This is often accomplished by comparing allelic differences between isolates using whole genome multi-locus sequence typing (wgMLST). Unfortunately, allele-based methods, like wgMLST, suffer from being highly species-specific, therefore limiting their current application to only commonly studied bacteria. This work aimed to address this limitation by developing an alternative population classification method based on the accessory genome that could be more universally applied, regardless of the bacterial species being studied. This was accomplished by comparing population assignments based on core SNPs to those derived from the phylogenetic analysis of gene presence/absence matrices output by common pangenome assembly software (i.e., Panaroo or Roary).

Published: November 2022

Introduction: Dental fear and anxiety (DFA) is a ubiquitous entity among dental patients in terms of their prevalence and incidence. It is among the major clinical problems in dentistry. In addition, the differences in DFA prevalence were present considering the age and gender of patients and over time, but with some opposite reports. The aim of this study is to examine the prevalence of DFA presence in children concerning their age, gender, and over time.
Methods: The survey sample comprised 200 of 9–12-year-old children. The DFA presence was determined twice by the modified version of the CFSS-DS scale (CFSS-DS-mod scale) during a 6-months long period between the first and the subsequent dental appointment due to the need for restorative dental treatment. The scale was applied before the restorative treatment started on both occasions.
Results: The prevalence of DFA was 17.5% in the study sample and decreased over time. It was slightly higher in girls.
Conclusions: The DFA prevalence in 9–12-year-old children is decreasing over time. Latent manifestations of DFA presence should be considered for evaluation in the future.
Research-Based on Telecommunication in Mobile Service Provider's Performance using Enhanced Naive Bayes Classifier
Authors: Dhabliya Dharmesh
Published: November 2022

In recent years, mobile service providers have rapidly expanded across all countries. Considering unpredictable development trends, mobile service providers are essential to knowledge-based service businesses. Performance may be improved by creating and disseminating new information through innovation activities based on the usage of business intelligence. This research examined the performance of mobile service providers across all countries utilizing an enhanced Naive Bayes classifier based on telecommunication. In comparison to quantitative variables, the naive Bayes performs quite well. In the beginning, data is collected and the normalization technique is used for data preprocessing. Feature extraction is carried out using “Term Frequency and Inverse Document Frequency (TF-IDF)”. “Decision Tree algorithm” is used for data analysis. Then the feature is selected using a two-stage Markov blanket algorithm. Enhanced Naïve Bayes Classifier is the proposed algorithm for telecommunication analysis and at last, the performance of the system is analyzed. This proposed algorithm is used to compare the mobile service provider's performances with existing algorithms. The proposed method measures the following metrics as Throughput, Packet loss, Packet duplication, and User quality of experience. The proposed algorithm is more effective and produces better results.
Brain Tumor Image Processing Using Fine-Tuned Resnet-101 Classification Model
Authors: Gupta Jatin
Published: November 2022

Medical image processing relies heavily on the diagnosis of brain tumor images. It aids doctors in determining the correct diagnosis and management. One of the primary imaging methods for studying brain tissue is MR imaging. In recent years, deep learning techniques have shown significant potential in image processing. However, the modest quantity of medical images is a restriction of the classification of medical images. As a result of this restriction, fewer medical photos are available. Fine-tuned ResNet-101 (FR-101) is proposed to classify the brain tumor images to counteract this issue. Weiner filter is used to de-noise the acquired raw MR images, and the adaptive histogram equalization technique is used to improve contrast. A stacked autoencoder is utilized in the segmentation procedure to separate the tumor from healthy brain parts from the preprocessed data. The marker-based watershed technique is used to identify the tumor location and structure in the segmented data. The recommended approach is then used in the classification stage. To obtain the highest level of accuracy for our research, accuracy, precision, f1-score, recall, and mean absolute error are the measures of success are studied as well as a comparison of the suggested approach with a few other existing methods.

For the FD/2 circuit, E-TSPC Pass Transistor logic uses 1.77 µW, whereas TSPC logic consumes 5.57 µW for the FD 2/3 circuit. It implies that the TSPC logic is the best solution since it meets the speed and power consumption requirements.
AI based Pilot Contamination Analysis for 5G MIMO based on Multi Antenna Routing Networks and Multi-User Pilot Scheduling
Authors: Sherje Nitin
Published: November 2022

Pilot contamination, a type of inter-cell interference, limits performance of large multi-input multi-output (MIMO) antenna systems.A drawback that results in ineffective bandwidth use is the burden of pilots who must estimate the channel regularly due to the acquisition of channel state data for channel estimation.Thus, there is a trade-off between spectral efficiency (SE)as well as quantity of pilots needed to evaluate channel.This research proposes novel technique in pilot contamination analysis (PCA) for 5G network based on MIMO by multi antenna routing system. The main aim is to detect pilot contamination and enhance spectral efficiency of the network. Here pilot contamination is detected using multi-user pilot scheduling with convolutional adversarial training model. As a result, a security breach occurs when crucial information slips to Eve during downlink transmission.Ability of the legitimate user to maintain secrecy can be greatly enhanced by knowing of an active eavesdropper.We also analyse the likelihood of detection, the likelihood of a false alarm, and the likelihood of a detection error.Simulation results show that suggested strategy to find PCA is effective.the proposed technique attained SINR of 72% , spectral efficiency of 85%,normalized MSE of 73%,PCA detection accuracy of 95%.

Authors: Marsyanova Yuliya A. , Zvyagina Valentina I. , Petrov Artem V.
Published: November 2022

Background. The molecular mechanism of NO effects in adaptation to hypoxia is of interest as a potential point of application in the therapy of fertility disorders.
Aim. To assess the degree of oxidative modification of epididymal mitochondrial proteins during hypoxia under conditions of experimentally modified NO synthesis.
Material and methods. Sexually mature rats were divided into four groups of 8 individuals: (1) control (animals without hypoxia); (2) chronic normobaric hypoxia, the animals were kept in a sealed chamber with oxygen reduced to 10% once a day for 14 days; (3) animals with hypoxia were injected with an inhibitor of the synthesis of nitric oxide (II) L-nitroarginine methyl ester at a dose of 25 mg/kg intraperitoneally once a day for 7 days; (4) animals with hypoxia were injected with the substrate for NO synthesis L-arginine at a dose of 500 mg/kg intraperitoneally once a day for 10 days. In the mitochondrial fraction of the head and tail of the epididymis, the activity of superoxide dismutase, the amount of NO metabolites, and the degree of oxidative modification of proteins were evaluated. Statistical analysis was performed using the ShapiroWilk, MannWhitney, and Spearman tests; differences were considered significant at p 0.05.
Results. Hypoxia led to an increase in the oxidative modification of proteins in the mitochondria of the head of the epididymis 319.12 [240.98; 363.63] c.u./mg protein relative to control 17.89 [15.31; 27.62] c.u./mg protein, p=0.0009. In the mitochondria of the tail of the epididymis, the oxidation of proteins under the studied conditions was less pronounced. The use of L-nitroarginine methyl ester, as well as L-arginine, led to a decrease in the level of oxidative modification of proteins in the head of the epididymis relative to the hypoxia model 39.89 [29.25; 43.17] and 37.25 [34.91; 40.96] c.u./mg of protein, respectively, p=0.0009.
Conclusion. Mitochondrial proteins in the head of the epididymis are more susceptible to oxidative damage during hypoxia; a decrease in the level of NO metabolites under conditions of oxygen deficiency is associated with a decrease in the oxidative modification of mitochondrial proteins.

Nanoparticles display entirely novel physicochemical characteristics for specific applications because of their exceptional size and shape. Owing to the present study, we reported biosynthesis, characterization and antibacterial properties of Cineraria maritima (Cm) assisted silver nanoparticles (Ag NPs). The surface plasmon vibration, crystalline structure, surface morphology, elemental composition, and possible functional molecules vibration of prepared Cm-Ag NPs were characterized by different instrumentation techniques. The spectrum of UV-Vis of Cm-Ag NPs showed maximum plasma intensity occurred around 425nm. XRD spectrum showed the face-centred cubic (FCC) nature of Cm-Ag NPs. The SEM image of the Cm-Ag NPs demonstrated a predominantly spherical shape with cluster formation of small particles to large particles with sizes ranging from 21.57 nm to 39.16 nm. EDS spectrum indicated the existence of Ag elements in Cm-Ag NPs. FTIR intense peaks of Cm-Ag NPs showed the different functional molecules such as phenol, alkene, aldehydes, and a carbonyl group. In addition, Cm-Ag NPs coated textile cotton fabric sample showed substantial anti-bacterial properties against a tested bacterial pathogen.

Published: November 2022

Zinc oxide nanoparticles (ZnO NPs) are a novel and alternative biomaterial for active biomedical applications among all metal and metallic oxide nanoparticles due to less toxicity and biocompatibility with human cells. In this study, we studied the growth curve of Serratia marcescens and Enterococcus faecalis to identify the mid-log phase of the bacterial growth to perform the exposure with ZnO NPs for investigating the antibacterial efficacy. The INT assay was used to determine the anti-bactericidal efficiency of ZnO NPs against S. marcescens and E. faecalis. The results showed that both the test bacteria attained the mid-log phase at the 5th hour. The determination of minimum inhibitory concentration (MIC) demonstrated a higher efficacy of ZnO NPs on the Gram-positive bacterium E. faecalis compared to the Gram-negative bacterium S. marcescens. The present study reports a higher susceptibility of Gram-positive bacterium over Gram-negative bacterium to the treatment of ZnO NPs.

The existence of antibodies against IBR was investigated in 92 serum samples obtained systematically from 55 cattle herds using Indirect-ELISA. A questionnaire interview was done to collect individual and herd-level data. The association between categorical variables and the outcome variable (seropositive) was assessed by bivariate analysis and multivariate logistic regression analysis in SPSS version 19.0. The seroprevalence of IBR was 18.48% (95% CI: 11.1-27.9), and district, breed, and herd size were identified as potential risk factors for IBR seropositivity. Significantly higher risk for IBR was found in Chitwan (Percentage-Positive “PP” = 36.37%; Odd ratio “OR” = 5.211; p = 0.008) than in Nawalpur (PP = 9.38%; OR = 0.931) and Rupandehi (PP = 10.00%). PP of IBR was significantly higher in Jersey crosses (PP = 30.00%; OR = 2.893; p = 0.048) than Holstein Friesian crosses (PP = 12.90%). Similarly, herds with more than 10 cattle (PP = 33.33%; OR = 4.167; p = 0.042) were found significantly at higher odds for seropositivity than herds having less than 10 cattle (PP = 10.71%). Due to the moderate prevalence of IBR among cattle in Nepal, this study recommends conducting additional planned research on IBR at the national level to safeguard the country's dairy businesses from potential financial losses.

Rats are reported to be the intermediate hosts and reservoirs of several zoonotic protozoal diseases. Trypanosoma lewisi is commonly reported in rats’ blood and is considered non-pathogenic protozoa in humans. However, some countries documented several cases in humans with T. lewisi infection. Another zoonotic protozoon that develops in rats and can be transmissible to humans is Toxoplasma gondii. We intended to present the morphology and morphometry of T. lewisi and T.gondii in wild rats collected around Malang City to explore the potential risk of transmission nearby. The rats were collected using single live traps followed by identification, sexing, age approximation, and body morphometry. All specimens were euthanized according to the standard procedure followed by blood and peritoneal fluid collection. The fluid smear preparation and Giemsa staining were performed to detect the presence of T. lewisi and T. gondii. Morphologic and morphometric analyses were conducted using ImageJ software. Among the collected 50 collected rats, 23 were identified as Rattus norvegicus (46%), 22 as Rattus rattus (44 %), and 5 as Mus musculus (1%). In the case of protozoans infection, ten individuals were infected with T. Lewisi (20%) from the blood smear check, whereas peritoneal fluid smear examination revealed an infection of T. gondii in a specimen (2%). Results of the study proved trypanosomiasis and toxoplasmosis in wild rats in Malang City. Though the clinical significance to human and public health impact is questionable, further research and surveillance of rodent-borne parasitic pathogens will provide more information for pre-emptive action.

Raphanus raphanistrum and R. pugioniformis (Brassicaceae) are wild radishes, native to the Eastern Mediterranean region. This study aimed to evaluate the effect of growing soil media (perlite, sand, and terra rossa) on the growth performance of two Raphanus species. For this, seeds of the selected species were germinated and seedlings were transferred to plastic cylinders, filled with growing soil media. At harvest, various growth parameters including shoot length, shoot fresh weight, shoot dry weight, root length, root fresh weight, and root dry weight were determined. Root and shoot fresh and dry weight, before and after oven dry for 24 h at 70 °C was measured. Results of the study revealed statistically significant differences (P value ≤ 0.05) among the various studied growth parameters for the selected Raphanus species and are affected by different growing media including types of soil and growing time (days after potting from 33 to 78). After 33 days of potting, the average shoot length for R. pugioniformis was found 6.6, 8.0, and 8.6 cm in terra rossa, sand, and perlite growing media respectively. On the other hand, the fresh (0.8, 1.6, and 2.5g) and dry (0.25, 0.48, and 0.72g) shoot weight for R. pugioniformis was reported in terra rossa, sand, and perlite soil media respectively. From the results of the study, it can be concluded that among the tested growing media, perlite growing medium is the best medium for the growth of both studied Raphanus species. This study demonstrated that the three studied growing media affected all the growth performance parameters of both Raphanus pugioniformis and Raphanus raphanistrum differently.

Cumin (Cuminum cyminum Linn) is an annual plant of the family Umbelliferae, with its use dating back to ancient times when it was cultivated for its medicinal and culinary potential. Cumin seeds could contain a wide variety of phytochemicals, including alkaloids, coumarins, anthraquinones, flavonoids, glycosides, proteins, resins, saponins, tannins, and steroids. In particular, linoleic acid, one of the unsaturated fatty acids found in abundance in cumin oleoresin, is credited with promoting good health. Many of cumin's purported biological actions in livestock and poultry have been attributed to flavonoids such as apigenin, luteolin, and glycosides. Cumin has several healthful qualities, such as antibacterial, insecticidal, anti-inflammatory, analgesic, antioxidant, anticancer, anti-diabetic, anti-platelet aggregation, hypotensive, bronchodilatory, immunological, anti-amyloidogenic, and anti-osteoporotic properties. Cumin supplementation may improve milk production and reproductive function in dairy cows by altering the feeding pattern of bacteria in the rumen, encouraging the growth of beneficial microbes, or stimulating the secretion of certain digestive enzymes. Because of the low price of cumin seed, it could be concluded that its inclusion in the diet might be beneficial to the commercial poultry industry and reduce the overall cost of egg and meat production. In recent years a rise in cumin's popularity has been seen as a result of the herbal movement spearheaded by naturopaths, yoga gurus, advocates of alternative medicine, and manufacturers of feed additives. Animal nutritionists are exploring the use of cumin for its potential to boost growth, improve nutrient usage efficiency, and reduce greenhouse gas emissions. This mini-review discusses how cumin could be used as a feed ingredient to boost productivity and ensure healthy animal reproduction.

Carbamazepine (CBZ) is a ubiquitous pharmaceutical pollutant found in various water environments. This is due to the ineffective CBZ removal, despite employing advanced physiochemical treatment technologies in the current conventional wastewater treatment plants. Thus, bioremediation that utilizes enzymes in microorganisms' systems to bio-mineralize CBZ is suggested as an alternative or complementary technique to remove CBZ more effectively. However, information from published research on the biodegradation of CBZ, the toxicity of metabolites, or toxicity testing was rarely evaluated or assessed cohesively. This aspect is important because if bioremediation of CBZ produces toxic metabolites, it will defeat the main purpose of bioremediation. Thus, the focus of this review is to assess the effectiveness of fungi and bacteria in the biodegradation of CBZ, particularly by looking at the type of enzymes expressed, and the metabolites produced. In this review, information related to the fungal and bacterial species that were reported to degrade CBZ was collated from the published literature and analyzed. Results of the analysis showed that cytochrome P450, laccase, and manganese peroxidase were the common enzymes responsible to degrade CBZ. However, such enzymatic activities can sometimes produce epoxy-CBZ, which is a more toxic compound than the parent compound. Only the fungus Pleurotus ostreatus was able to oxidize epoxy-CBZ via the acridine pathway into acridone, the latter a metabolite that is susceptible to further biodegradation into nontoxic metabolites. However, the identity of the end metabolites is not reported nor characterized. Further, Pseudomonas spp. is the most promising bioremediating agent since it can metabolize CBZ into catechol, the latter can enter the carbon central pathways to generate energy for the bacterial cells.
Potential of lignocellulolytic biocatalysts of native and proposed genetically engineered microbial cell factories on jute fiber modification and jute waste recycling: A review
Authors: Das Somnath , Ghosh Dipankar
Published: November 2022

The lignocellulolytic microbial systems from different parts of the world responsible for lignocellulosic biomass (LCB) like jute (Corchorus spp.) waste degradation, fiber modification, and bioenergy production are not limited to a specific prokaryotic or eukaryotic group. The industrial applications of these highly efficient bacterial, fungal and algal communities are related to the production of lignocellulolytic enzymes such as cellulase, hemicellulase, lignin-peroxidase, versatile peroxidase, laccase, thermostable oxidants, pectinase, etc. They are a blessing for the jute, dye, paper, pulp, and biofuel industries as they help to generate a sustainable ecosystem. The jute plant is lignocellulosic biomass so it can be utilized in various ways, from everyday goods to power generation. Jute industries generally use different physicochemical strategies to generate quality fiber and post-retting activities, but these approaches cannot produce desired products; hence microbial routes are best for quality fiber generation, waste remediation, and biofuel generation. To this end, this review summarizes the most important milestones of the development of the leading enzyme-producing cell factories and their engineering by genetic, metabolic, and synthetic biology approaches with the emergence of high throughput methods, such as site-directed mutagenesis and others that can analyze the relevant mutations to accelerate our understanding of lignocellulolytic enzymology.
