Brain tumor segmentation network: A study through interactive image selection and neural-nets training method
Authors: Rama Raju V
Published: January 2025

Medical image segmentation is a pertinent issue, with deep learning being a leading solution. However, the demand for a substantial number of fully annotated images for training extensive models can be a hurdle, particularly for applications with diverse images, such as brain tumors, which can manifest in various sizes and shapes. In contrast, the recent Feature Learning from Image Markers (FLIM) methodology, which incorporates an expert in the learning process, has proven to be effective. This approach generates compact networks requiring only a few images to train the convolutional layers without backpropagation. In our study, we implement the interactive—technique for image collection plus neural-nets-training with reference to F.L.I.M, exploring the user’s knowledge. The results underscore the efficacy of our methodology, as we were able to select a small set of images to train the encoder of a U-shaped network, achieving performance on par with manual selection and even surpassing the same U-shaped network trained by backpropagation with all training images. Index Terms—Deep Learning, Brain, Tumor, Segmentation, Interactive Machine Learning.

Published: January 2025

Attenuation of hemodynamic responses to laryngoscopy and intubation is major concern during conduct of general anaesthesia. This study compared the efficacy of intranasal versus intravenous Dexmedetomidine for attenuation of these hemodynamic responses.

Prospective double blind randomized controlled study was conducted on 90 participants randomized in 2 groups - Group DIN (n=45) received Intranasal Dexmedetomidine (1 µg/kg of 100µg/ml preparation) 40 minutes preinduction and Group DIV (n=45) received Intravenous Dexmedetomidine (0.5µg/kg of 200µg in 40 ml normal Saline infusion) 10 minutes preinduction.

Primary objective was to compare hemodynamic parameters in both groups every 10 min from drug administration till induction, at intubation and till 30 min postinduction. Secondary objective was to compare postoperative sedation in both groups at variable intervals. Data was analysed in statistical software Epi Info Software version 7.

No significant hemodynamic response to laryngoscopy and intubation seen above baseline values in both groups. Group DIV showed lower values than DIN at laryngoscopy-intubation (P=0.0095) and postintubation phase till 7min (P=0.0016) in terms of MAP. No significant difference in postoperative sedation in both groups.

Intravenous and intranasal Dexmedetomidine equally attenuate hemodynamic responses to laryngoscopy and intubation during general anaesthesia with similar postoperative sedation. Intranasal Dexmedetomidine had steadier hemodynamics than intravenous Dexmedetomidine.
A prospective randomized study comparing the efficacy of intrathecal clonidine versus dexmedetomidine as adjuvants to hyperbaric bupivacaine in patients undergoing spinal anesthesia for pelvic and lower limb orthopedic surgeries

Published: January 2025

Low-dose bupivacaine used in spinal anaesthesia results in speedy recovery. Adjuvants could be added to provide sufficient anaesthesia for surgery. Dexmedetomidine and clonidine are selective α-2 adrenoceptor agonists and are used as adjuvants in different doses to prolong the duration.

Aim is to determine time of onset of motor and sensory block, time to achieve highest level in sensory block, duration of motor block and sensory block and need for first rescue analgesia and any side effects.

Fifty patients scheduled for lower limb and pelvic orthopedic surgeries under spinal anesthesia were divided into two groups. The dexmedetomidine group (D10, n=25) received 3.4 ml of 0.5% heavy bupivacaine combined with 10 µg of dexmedetomidine, totaling 3.5 ml. The clonidine group (C15, n=25) received 3.4 ml of 0.5% heavy bupivacaine with 15 µg of clonidine, also totaling 3.5 ml, administered intrathecally.

The onset of sensory and motor block was significantly earlier, and the duration of both motor and sensory block was longer in the dexmedetomidine group compared to the clonidine group (p-value < 0.05). Additionally, the time to first rescue analgesia was significantly extended in the dexmedetomidine group, which also reported better quality of postoperative analgesia compared to the clonidine group.

Intrathecal administration of bupivacaine with 10 µg of dexmedetomidine results in an earlier onset and longer duration of both sensory and motor block compared to 15 µg of clonidine. This combination also provides increased analgesia time and delays the need for the first rescue analgesia. Dexmedetomidine proves to be a superior adjuvant to clonidine, enhancing patient satisfaction and offering better quality of analgesia.

Published: January 2025

Erector spinae block (ESB) is an innovative regional anaesthesia technique that has gained popularity for managing postoperative pain, particularly following thoracic and abdominal surgeries. This case series demonstrates five patients who received Erector spinae block as part of their pain management protocol during diverse surgical procedures, including mastectomy, open cholecystectomy, video assisted thoracoscopic surgery (VATS), total abdominal hysterectomy and right radical nephrectomy. This case series signifies the efficacy of Erector spinae block in optimizing pain management and providing opioid free analgesia across various surgical contexts, highlighting the need for further research to expand its clinical applications. The postoperative pain scores in all the cases was low, patients reported pain scores averaging between 2 and 3. This helped in reduced opioid consumption post operatively with minimal side effects and in turn facilitated quicker recovery and discharge.

Published: January 2025

The study aimed to prepare a nanocapsules formulation from the acetonic extract of Moringa oleifera leaves, using polymeric capsules, and test its toxicity against the third instar larvae of Culex pipiens mosquitoes. The leaf extract was prepared using acetone as a solvent, and the nano polymeric capsules were prepared using the synthetic polymer polyethylene glycol 4000. The results showed the successful preparation of nano polymeric capsules from the leaf extract, with an average particle size of 259.2 nm, and a nanocapsule diameter of 263.83 nm, as determined by DLS and SEM analysis, respectively. The toxicity results indicated that the nano polymeric capsules of the leaf extract exhibited higher mortality rates, reaching 97.6% at a concentration of 1333 ppm, with a median lethal concentration (LC50) of 421.56 ppm. In comparison, the traditional leaf extract showed higher mortality rates of 100% at a concentration of 6125 ppm at 72 h of treatment, with a median lethal concentration (LC50) of 1719.67 ppm. These results demonstrate that the nano polymeric capsules of the leaf extract are more efficient than the traditional extract, even at lower concentrations, and could serve as an environmentally-friendly and effective means of mosquito control.

The fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is a serious pest known for its ability to feed on various crops, particularly maize, inflicting significant reduction in maize yield. Farmers have traditionally dependent on chemical insecticides to manage this pest. These insecticides are frequently ineffective because the pest’s hidden feeding habits hinder the chemicals from reaching their intended target. In response to this challenge, an in vitro bioassay was performed to evaluate the virulence of an entomopathogenic nematode Steinernema siamkayai against third-instar larvae of Spodoptera frugiperda and wax moth (Galleria mellonella) at different concentrations of infective juveniles. Mortality rates were monitored from 24 to 96 h post-inoculation, with S. siamkayai demonstrating notable effectiveness against both insect species. For the fall armyworm, mortality rates risen progressively, beginning at 16.66% for 100 IJs larva-1 after 24 h, reaching 83.33% at 48 h, and achieving 100% by 96 h for doses of 30 IJs larva-1 or more. Wax moth larvae, on the other hand, showed greater susceptibility, with 22.91% mortality at 5 IJs larva-1 within 24 h and 100% mortality at 100 IJs larva-1 by the 48-hour mark. After 96 h, complete mortality was recorded in both species at doses of 30 IJs larva-1 or higher. Probit analysis indicated lower LC50 values for G. mellonella (1.83 and 0.87 IJs larva-1 at 72 and 96 h) compared to FAW (9.83 and 5.47 IJs larva-1). These findings suggest that S. siamkayai is a highly efficient bio-control agent, especially for managing S. frugiperda, and shows potential for integration into pest management programs.

Published: January 2025

In vitro studies were carried out at Institute of Rice Research, PJTSAU, Rajendranagar, Hyderabad, in 2023 to assess the compatibility of biopesticides with chemical pesticides applied at drone and Taiwan sprayer concentrations. The possibility of utilizing both biopesticides and chemical pesticides together with drone for managing major rice insect-pests and diseases was explored. The compatibility of Bacillus thuringiensis var. kurstaki with four insecticides (flubendiamide 39.35% SC, chlorantraniliprole 18.50% SC, cartap hydrochloride 50% SP and tetraniliprole 18.18% SC) and Pseudomonas fluorescens with three fungicides (propiconazole 10.7% + tricyclazole 34.2% SE, tebuconazole 50% + trifloxystrobin 25% WG and propiconazole 25% EC) was determined by following the inhibition zone technique on suitable media with sterile filter paper discs. Bacillus thuringiensis var. kurstaki combinations tested with flubendiamide 39.35% SC, chlorantraniliprole 18.50% SC, cartap hydrochloride 50% SP exhibited slight inhibition over control while, tetraniliprole 18.18% SC exhibited high compatibility with B. thuringiensis var. kurstaki without any growth inhibition at both drone and Taiwan sprayer concentrations. Similarly, all the tested fungicides were found compatible with P. fluorescens, displaying negligible growth inhibition compared to the control. Notably, tebuconazole 50% + trifloxystrobin 25% WG showed cent per cent compatibility with no growth inhibition at both drone and Taiwan sprayer concentrations. These findings underscore the potential for seamlessly integrating biopesticides with chemical pesticides, paving the way for effective management of pests and diseases without compromising efficacy, particularly as a pesticide resistance management strategy.

Published: January 2025

In 2023, comprehensive studies of shallow-water methane gas emissions were conducted during expeditionary work in the coastal area of Laspi Bay (southwestern coast of Crimea). The research included determining the component and isotopic composition of bubble gas, measuring methane concentration in the gas emission area, estimating bubble flux rates, and measuring hydrophysical parameters above the seep site. The obtained results of the carbon isotopic composition of methane and ethane in the studied samples corresponded to (δ13Cmean = –36.0 ± 0.8‰, δ13Cmean = –37.5 ± 0.2‰, respectively) and indicate the presence of thermocatalytic methane migration along fault systems. It was found that the methane seeps of the Crimean coast are relatively low-flow, with a specific flux ranging from 5 to 10 m3 year-1 from an individual seep. The presented temporal dynamics of dissolved СН4 concentration above the seep and changes in the isotopic ratio of δ13C-СН4 in bubble gas indicate the constancy of the process over time and the absence of connection with external hydrological changes in the water area. The obtained ratios of the carbon isotopic composition of methane and ethane demonstrate that the gas mixture was most likely generated from source organic matter of marine origin, and one of the main sources of hydrocarbon fluids is the Upper Eocene and Oligocene deposits in the Western Black Sea basin.

The Dagestan offshore of the Caspian Sea, surrounded on all sides by oil and gas bearing areas, represents an exceptional interest for the exploration of hydrocarbon fields.

The applied sequence stratigraphic analysis allows to stratify the Cenozoic section for the resource’s estimation of the Karagan-Chokrak deposits in new prospective offshore areas. The analysis used well data from the onshore and Dagestan offshore, as well as 2D seismic data.

Five sequences were identified in the Cenozoic sediments according to the seismic and well data, from bottom to the top: Maikop SQ1, Chokrak SQ2, Sarmatian SQ3, Akchagyl SQ4, and Apsheron SQ5, in each of them regressive and transgressive tracts have been identified. The boundaries of regressive and transgressive tracts in wells were distinguished on the basis of a mathematical model proposed by the authors for the automated geological interpretation of gamma-ray logging. For evaluation the petrophysical properties of the reservoir rocks the volumetric mineralogical model has been created.

Published: January 2025

The article considers the results of applying a multi-layer approach to the quantitative interpretation of electrical and induction logging data in vertical wells for formation evaluation of the Achimov formation in the central part of Western Siberia. Interpretation of electrical logging data by conventional methods often leads to errors in estimating the oil saturation of thin reservoirs due to the complex apparent resistivity logs, which are significantly influenced by the high-contrast invaded zones and shoulder beds. The approach proposed at Institute of Petroleum Geology and Geophysics of the Siberian Branch of the Russian Academy of Sciences is based on joint multilayer 2D inversion of signals from a complex of galvanic and induction probes. The signals are calculated using a verified finite element algorithm. This naturally takes into account changes in the well diameter and drilling mud resistivity, radial and vertical distribution of electrical properties in the section, different sensitivity of the signals to various elements of the environment around the logging tool, as well as design parameters of the most common Russian electrical logging tools. The approach has been tested on logging data provided under an agreement with SNIIGGiMS. Geoelectric models of Lower Cretaceous deposits were built for several dozen wells, typical examples of which are given in the article.

This article reviews the evolution of hydraulic fracturing (HF) technologies for the carbonate sediments of the kashirsky and podolsky horizons of the Arlanskoe oilfield (the Republic of Bashkortostan and the Udmurt Republic) by the influence of changes in current development conditions, reserve depletion, clarification of the geological structure, and scientific and technical advancements. It presents an overview of the main technologies of primary hydraulic fracturing and re-fracturing actively used today and/or are being introduced on the industrial scale. For horizontal wells, hydraulic fracturing with hydraulic jet perforation (HJP) is employed. This technology enables the development of previously untapped or underperforming sections of the wellbore by allowing selective acid and proppant injection into specific intervals, offering high controllability and predictability. Both HJP and HF stages are completed in a single tripping operation without the need for a coiled tubing fleet. For directional wells, high-tonnage hydraulic fracturing with increased proppant mass up to 40–50 tons is a promising technological solution. This approach enhances to increase starting oil flow rates by improving coverage ratio due to involving poorly drained and previously undeveloped overlying and underlying layers. The article consolidates practical experience with hydraulic fracturing technologies, analyzes their effectiveness, identifies the features of hydraulic fracturing in directional and horizontal wells, and develops an algorithm for the selection of hydraulic fracturing technology for the conditions of a carbonate reservoir.

The paper presents new data on the structure and composition of ultramafic rocks in the eastern part of the South Kraka massif. It is shown that the studied area is composed predominantly of spinel peridotites, among which the main role belongs to lherzolites with a low content of clinopyroxene (2–5%) and harzburgites, among which lens-shaped and bandshaped inclusions of monomineral olivine rocks – dunites – are quite often observed. The leading role in the structure of the rocks belongs to high-Mg olivine (Fo87-94), a secondary role (2016). Nature of the lithospheric mantle beneath the Arabian Shield and genesis of Al-spinel micropods: Evidence from the mantle xenoliths of Harrat is played by high-Mg orthopyroxene (enstatite) and Ca-Mg clinopyroxene diopside. Rare minerals of the mantle stage are amphibole and plagioclase. A typical accessory mineral of ultramafic rocks is spinel, the composition of which varies from high-Al in lherzolites (Cr# = 0.16–0.3), to moderate-Al in harzburgites (Cr# = 0.3–0.55) and to high-Cr in dunites (Cr# = 0.6–0.85). Of the rare accessory minerals in the rocks, the following were identified: native copper, pentlandite, awaruite and PGM (laurite, irarsite, Os-Ir-Ru-alloys). The section of mantle ultramafic rocks of the Sargan Range completed its high-temperature evolution to the levels of the plagioclase peridotite facies, partly in the transition zone from spinel to plagioclase facies. An assessment of oxygen fugacity allows us to speak about more reducing conditions for the formation of rocks of the studied area compared to other similar formations of upper mantle origin and allows us to classify the studied ultramafic rocks as moderately depleted restites of the upper mantle under the riftogenic structure of the Paleo-Ural basin. The geochemical specialization of PGM also indicates a restite origin of ultramafic rocks. At the stage of cooling and tectonic transformations in the crust, ultramafic rocks underwent serpentinization.
Ræstar hugleiðingar - upprunin til sagnorðið 'ræsa'
Authors: Steintún Bjarni
Published: January 2025

In this article the verb ræsa with the meaning ‘let (something) ferment’ is examined. The Faroese word is examined in its Nordic linguistic context and an attempt is made to analyze its linguistic origin. Two possibilities are then discussed: one with the origin in the noun rás, and the other with the origin in the Old Norse hrár (raw) or hræ (cadaver). In addition, the question of homonymy or polysemy will be addressed, i.e. it is assessed whether the three ræsa verbs found in Føroysk orðabók (the Faroese Dictionary) should be listed as a single verb. The work was carried out by examining what the various etymological dictionaries of the neighbouring languages ​​tell us about ræsa and its cognates, and by assessing the phonological and morphological relationships between them. It was concluded that ræsa can be said with reasonable certainty to be a single polysemous word, which at some point in history was derived from the noun rás. The word originates from Proto-Norse, as it appears to have been formed according to Proto-Norse patterns.

Research of salt tolerance mechanism of sandy shrub Tamarix spp
Authors: Liu Hongxia
Published: January 2025

6.5% of the world's total land area is saline-alkali land, and more than 800 million hectares of saline soil are distributed worldwide. Soil salinization has become an important constraint on global food security and ecological security. Tamarix is a typical salt-secreting halophyte, which can excrete the salt in the plant from the body. The use of plant resources to transform saline-alkali soils has fundamentally alleviated soil salinization compared with traditional methods. Therefore, the research on the salt tolerance mechanism of tamarisk is very important to alleviate the problem of the shortage of cultivated land resources.

Dromedaries have been evolved a remarkable array of adaptations that enable them to live in harsh desert environments. These adaptations are evident in their body systems, which are specifically designed to conserve water, regulate temperature and withstand extreme conditions. The unique characteristics of camel body systems were described to withstand extreme environmental conditions. Furthermore, growth and reproductive performances in addition to milk and urine secretion and unique characters under harsh condition were presented. Therefore, the articles concerning unique characteristics of camel body systems resulting in adaptation to harsh condition in addition to growth, reproduction, milk and urine secretion were used for writing the manuscript and they were collected from google scholar, ScienceDirect, PubMed databases. The results indicated that camel body systems have unique features indicated in anatomical, physiological and behavioral adaptation that enable them to survive in harsh environmental conditions. The camel’s respiratory system has several adaptations including long and convoluted nasal passages, a large lung surface area and low respiration rate to conserve water. Lifespan of camel RBCs lasts 90-150 days and they are oval-shaped with special plasma membrane characters resulted in high tolerance to osmotic stress and efficient oxygen transport. Camels’ forestomach have unique pouch-like structures contributed to conserve water. It is worth noting that there are no seminal vesicles in Camelidae family and the ejaculated semen is viscous. She-camels are seasonal breeding animals with induced ovulation and diffused placenta. Growth and reproductive performances in addition to milk and concentrated urine secretion occur during these extreme harsh conditions. Intensive management system resulted in significant improvement in both productive and reproductive performances. It could be concluded that dromedaries is well-adapted to withstand extreme conditions in addition to their abilities to produce and reproduce.
La ὀργή de Εurídice en Ηipsípila de Εurípides: una encolerizada y juiciosa experiencia femenina
Authors: Gallegos Luciana
Published: January 2025

El objetivo del artículo consiste en analizar la cólera que experimenta Eurídice contra la protagonista por la muerte de su hijo en Hipsípila. La involuntariedad del fallecimiento, aspecto determinante en el análisis aristotélico de ὀργή en Retórica, es juzgada por la monarca en el segundo episodio tras escuchar el testimonio de Anfiarao en favor de Hipsípila. En consonancia con lo esbozado por Aristóteles, Eurídice depone su cólera al verificar la naturaleza accidental del deceso.
Aristóteles, entre la política y la biología: la dominación del ciudadano varón en la Grecia antigua
Authors: Gallego Julián
Published: January 2025

Este artículo analiza cómo Aristóteles concibe la dominación del ciudadano varón en la Grecia antigua. Si bien en Política el bárbaro como esclavo por naturaleza parece ser lo opuesto del ciudadano, cuando se consideran las obras biológicas de Aristóteles la oposición que se diseña es entre varón ymujer. Este sustrato biológico, que se entrecruza con sus ideas acerca de las relaciones entre cuerpo y alma y materia y forma, se solapa con la dimensiónpolítica para derivar en una dominación irreversible del varón sobre la mujer, hecho que no sucede con el esclavo.
Sublimes aperire vias: Paralelismos textuales y coincidencias ideológicas en Manilio y Ps. Longino
Authors: Bravo López Ulises
Published: January 2025

El s. i d. C. inaugura, en muchos sentidos, la transformación de los paradigmas literarios tradicionales y la conformación de una nueva literatura. Dos textos de este siglo contribuyen a la fragua de esta nueva concepción: los Astronomica de Manilio y el Περὶ ὕψους atribuido a Ps. Longino. En este artículo se propone, a través del análisis de algunos de sus pasajes, un posible vínculo entre ambas obras, que se desprendería de una interacción literaria e ideológica de sus autores, originada en un mismo ambiente o círculo intelectual.
El Arrunte indiano: imitación lucanea en la Mexicana (1594) de Gabriel Lobo Lasso
Authors: Torres Magallón Jorge Luis
Published: January 2025

Entre la materia histórica que Gabriel Lobo Lasso de la Vega incluyó en el canto 22 de la Mexicana (1594) se encuentran los presagios de la caída de Tenochtitlán que relata López de Gómara en la Conquista de México (1552). Este trabajo examina cómo el poeta ficcionalizó el pasaje cronístico imitandoel Catálogo de prodigios de la Farsalia de Lucano y creando a Goro, personaje ficticio modelado a partir del Arrunte lucaneo. Se demuestra, además, que el poeta se valió de las traducciones castellanas de la Farsalia, hecha por Laso de Oropesa (1541), y de la Jerusalén liberada, hecha por Juan Sedeño (1587).

La masse forestière congolaise. Son implantation, ses divers faciès
Authors: Gilbert G.
Published: January 2025

La première partie de cet article traite de la répartition géographique des grandes régions forestières du Congo. L'auteur distingue trois grandes zones :- La zone littorale du Kouilou et la région montagneuse du Mayombé et de ses contreforts, où l'exploitation forestière a pris naissance.- Le massif du Niari-Chaillu, riche en Okoumé et en Limba, et donc très exploité.- La zone quasi intacte de 15 millions d'hectares comprenant le bassin du Congo, zone de transition et zone de hautes terres.A ces trois grandes zones forestières s'ajoutent les massifs isolés, les forêts galeries et les régions boisées dominées par les savanes.La deuxième partie passe en revue les différents types de forêts congolaises : la forêt à Okoumé, la forêt à Limba dans le sud et le centre du pays, et six types de forêts dans le nord : la forêt dense de terre ferme, la forêt secondaire, la forêt claire, la forêt à Gilbertiodendron, la forêt à copaliers et la forêt inondée.
