Mentha arvensis L. is a perennial herb and one of the main essential (menthol) oil producing crops cultivated worldwide. Mint oil is used as a stomachic, carminative, anaesthetic, disinfectant agent and has an indispensable role in pharmaceutical and aromatic industries. The most promising varieties of M. arvensis L. such as Himalaya, Kranti, and Kosi have been developed by CSIR-CIMAP and are under cultivation in various parts of India. In this study, different varieties of M. arvensis, cultivated for the production of planting material/sucker, were screened for soil-borne fungal infections. Various districts of Uttar Pradesh were surveyed, and vascular wilt disease incidences were found between 3-15 % in the year 2018. The districts Barabanki and Lucknow recorded a high percent (13- 15 %) of disease incidence on M. arvensis var. Kosi. Moderate incidence, 7% and 11%, of vascular wilt disease were observed on M. arvensis var. Himalaya in Barabanki and Lucknow, respectively. In comparison with other varieties, very few incidences (3-5%) were observed on Kranti variety at Sitapur, Raebareli and Lucknow districts. The vascular wilt causing pathogen (MaKf1) was isolated and characterized on the basis of colony morphology, microscopic examination of spores and molecular identification targeting the ITS region of the rDNA gene cluster and was identified as Fusarium proliferatum.

Essential oils derived from aromatic plants like mint species, lemongrass, palmarosa, citronella, vetiver, geranium etc are finding extensive usage in perfumery, flavoring, cosmetics and pharmaceutical industries. Some of these essential oils also possess strong mosquito repellency feature that make them potential candidates for utilization in the huge market of insect repellents and insecticides. In this context, the oils obtained from the hydro-distillation of mint, citronella and lemongrass leaves are in high demand for making herbal formulations/products used in house-hold hygiene and for mosquito repellency. Mosquitoe borne diseases such as dengue, malaria, filariasis and chikungunya have plagued the public health scenario, especially for the homeless people who live on roadsides and are under constant threat of mosquito bite. According to 2011 Census data about 449761 families in India are roadside dwellers. In the present study we have prepared an organic mosquito repellent renewable fabric finish using citronella oil as the base. Application of this product on fabrics has been found very effective in repelling the mosquitoes. Our study suggests that mixed or intercropping of mint species with citronella can be a profitable venture for farmers because of extra income that citronella oil can fetch for preparing above product.

Centella asiatica (L.) Urban (Family- Apiaceae) is a high-value medicinal plant that contains asiatic acid, asiaticoside, madecassic acid and madecassoside, etc. It is traditionally used as a wound healer and in various skin related diseases. It is propagated through stem cuttings or seeds. It has been observed that the seeds of this medicinal plant show considerable germination in laboratory conditions, whereas its germination is very low under natural environmental conditions. In the present study, efforts are made to distinguish between the viable and non-viable seeds of Centella asiatica (L.) Urban as the same plant bears seeds of different shapes and sizes. Colour thus may show seed heteromorphism. Seeds were collected at three time-frames; before the rain, at the initiation of rain, and during good rains in north India’s sub-tropical climate, and were classified among seven different categories based on shape, size and color. Results indicated that maximum germination (24%) was observed in the seeds, that were dark brown, swollen and collected during the initiation of rains. The lowest germination was observed in light brown-colored seeds. In addition, it has also been observed that in some categories (yellow-coloured seeds with the flattened shape) there was no germination.

Alstonia scholaris (L.) R. Br, commonly known as saptaparna is an evergreen tropical tree of medicinal value. In this study, the floral volatile oil composition and antibacterial activity of A. scholaris collected in the morning and evening times were investigated. A total of thirty-six constituents, forming 81.1-83.7 % of total composition were identified. The oil was characterised by the presence of a higher amount of oxygenated monoterpenes (60.3-66.7 %), followed by benzenoids (9.2-9.9 %). Major components of the oil were linalool (13.6-14.3%), cis-linalool oxide (furanoid) (7.3-12.2 %), trans-linalool oxide (furanoid) (7.0-7.5 %), cis-linalool oxide (pyranoid) (3.3-7.2 %), trans-linalool oxide (pyranoid) (3.8-4.7 %), terpinen-4-ol (7.9-10.6 %), and α-terpineol (6.3-6.6 %). The oil showed moderate to good activity against Salmonella typhimurium (MTCC 98), while it showed moderate activity against Escherichia coli (MTCC 739). It can be concluded that the collection time influenced the yield and chemical composition of A. scholaris floral volatiles.

Published: January 2024

The present study aims to determine the type of fodder available and the level of scarcity of Anoa’s fodder at the condition prior to captivity at the Forestry Research Institute of Manado. The method employed was a trial of 12 (twelve) types of fodder available around the captivity site given to 2 (two) female anoas. The data were analyzed and displayed in tables and graphs while the data of preferred fodder were analyzed using Neu’s index equation. The findings suggest that anoa put in captivity at the Forestry Research Institute of Manado did not encounter problems during the process of feeding adaptation. The average fodder needs required anoa at the captivity site of  the Forestry Research Institute of Manado range from 10.2 to 11.7 kg/ day in which the fodder was given twice a day. Meanwhile, based on the availability and ease of supplying the fodder from around the captivity site, the following are the types of fodder from higher to lower preferences, namely: field grass, kangkung, shoes banana, string beans, beans and cucumbers, respectively. While fodder with the lowest level of scarcity is the type of fodder with a hard texture such as sweet potatoes, carrots or potatoes. Based on the results of a number of studies, it is recommended that variations in anoa’s fodder can be done every 4-5 times a day.

Authors: Duran Merve Hacer , Türkcan Mehmet Buğra , Coşgun Baybars Sümeyye , Öçal Mustafa Çağdaş
Published: January 2024

Aim Cemento-ossifying fibroma (COF) is a mesenchymal, benign odontogenic tumor of the jaws that originates from the mesenchymal blast cells of periodontal ligament and can form osteoid, bone, cement-like tissue, fibrous cellular tissue or a combination of them. In this case report, it is aimed to present clinical, radiological and histopathological examination of two cemento-ossifying fibroma cases.
Case Report A 36-year-old systemically healthy female patient was referred to our faculty due to a lesion detected in the right mandibular posterior region. As a result of the clinical and radiological examination, an asymptomatic tumoral structure with a mixed appearance and regular borders was detected. No expansion was detected in the right mandibular posterior region. The patient was referred to the Department of Oral and Maxillofacial Surgery for biopsy. According to the biopsy report, it was learned that this tumoral structure was a COF. A 38-year-old systemically healthy female patient was admitted to our faculty due to gingival bleeding. As a result of the clinical and radiological examination, an asymptomatic lesion with a radiolucent appearance and sclerotic borders was detected in the right mandibular posterior region. According to the patient’s biopsy report, it was discovered that this lesion was a COF.
Discussion COF may exhibit different clinical and radiological behaviors based on its stage. Diagnosis and treatment planning of COF should be made with clinical, radiological and histopathological examination.
Conclusion Two COF cases are reported with their detailed clinical and radiological examinations in this paper.

Published: January 2024

Aim To report a rare case of heterotopic ossification (HO) between the maxillary right central incisor (tooth #11) and lateral incisor in a 47-year-old male patient Case Report A 47-year-old male patient presented with a painless, progressive-growing swelling in the anterior region involving the maxillary right central and lateral incisors for the past 6 months. The patient’s medical history was unremarkable. Intraoral examination revealed periodontal loss with prosthetic restorations in the affected region for over 10 years. Radiographs and cone-beam computed tomography (CBCT) images confirmed the presence of HO between the maxillary teeth. Discussion HO is a rare condition characterized by the formation of bone in soft tissues. It is most commonly seen after trauma or surgery, but it can also occur spontaneously. The exact cause of HO is unknown, but it is thought to be due to a combination of factors, including inflammation, injury, and genetic predisposition. In this case, the patient’s history of trauma may have contributed to the development of HO. The patient reported that he had sustained a blow to the anterior region of his mouth 10 years prior to the onset of the swelling. This trauma may have damaged the periodontal ligament, which may have led to the formation of HO. Conclusion This case report highlights the importance of considering HO in the differential diagnosis of painless, progressive-growing swellings in the maxillary region, especially in patients with a history of trauma.
La force de l’aveu comme intrigue cinématographique
Authors: Beauparlant Sophie
Published: January 2024

Par l’étude des pratiques dialogales des films Maelström de Denis Villeneuve et La Neuvaine de Bernard Émond, cet article questionne l’aveu, un acte de parole très présent dans les scénarios de films. Qu’il soit une révélation de laquelle émerge une intrigue ou encore ce vers quoi se dirigent les éléments du récit, l’aveu participe toujours à la tension dramatique au cinéma. Notre hypothèse est que la mise en scène de l’aveu, et de ses troubles périphériques, peut être à la fois l’un des éléments porteurs d’une intrigue cinématographique et cela même qui capte l’attention du spectateur. En reprenant notamment les concepts de mise en intrigue de Raphaël Baroni et de mise en phase de Roger Odin, nous proposons l’analyse du scénario de deux films québécois pour voir en quoi la parole échangée (ou non) peut être un véritable catalyseur narratif et un lieu de dévoilement de l’intériorité des personnages.
« La Guerre », ou le film vendangeur de Marcel Dugas
Authors: Chamberland Rafaël
Published: January 2024

L’article se veut une présentation suivie d’une lecture du poème « Film. La Guerre » paru dans le numéro de juin 1918 du Nigog, signé sous le pseudonyme de Hilaire Le Jeune par Marcel Dugas. Suite à une mise en contexte socio-historique (Richard, Lacasse, Djebabla) et biographique (Hayward, Dugas), nous procéderons à une lecture du poème en nous appuyant sur les concepts de posture (Garand) et de subversion de la notion de genre (Bonenfant, Filteau). Dans ce qui paraît être une triple génécité – conte allégorique, poème en prose et cinéma – nous discernerons les implications cinématographiques en lien avec la structure du poème et l’enchaînement des images verbales; une attention particulière sera portée à la présence envahissante du sang (Garonne, Durafour) et à comment elle contribue à inscrire précocement le poème dans une lignée cinématographique (Bazin, Durafour) et poétique (Apollinaire, Fondane). Nous nous pencherons aussi sur ce qui relie le film (et la guerre) à une autre figure antique : Cybèle (Borgeaud). Nous verrons comment ces implications diffèrent d’avec les premières tentatives de Dugas dans Psyché au cinéma (1916), le cinématographe n’inspirant plus un voyage intérieur dans une intimité démontée, mais au contraire, un regard sur la Nature. Ainsi, l’oeuvre ne se réduit pas au discours polémique de la revue, elle le dissout, le liquéfie à même la prose, alors que l’auteur emprunte une posture toute différente.
La région fertile. Geste, authenticité et territoire au cinéma et en littérature contemporaine
Authors: Auger Anne-Marie
Published: January 2024

La récente effervescence du cinéma d’auteur québécois a su jeter un éclairage nouveau sur des territoires trop peu colonisés par la fiction. Ces nouveaux lieux de l’imaginaire, qui représentent un des plus importants déplacements du « mouvement », permettent d’alimenter une réflexion sur l’appartenance au monde et les multiples transformations du chez-soi. Le retour au pays natal, après les épopées des années 90 et 2000, passe par une exposition banale des territoires endotiques et des hommes qui les habitent. Nous proposons d’analyser le « vivre ensemble » du jeune cinéma québécois des dix dernières années — qui semble avant tout marqué par un « vivre ici » — à travers la lentille du geste technique. Faire un noeud, allumer un feu, construire un camp, démarrer une motoneige : le néoterroir expose et révèle certains gestes. Le texte qui suit met en lumière certains liens existants entre les multiples transformations du cinéma québécois et les déplacements géographiques observables en littérature. Situés loin des terrasses « branchées » du Plateau Mont- Royal et de ses trentenaires désabusés, les récits néoruraux de la relève littéraire nous font découvrir la grandeur comme la misère de petites villes de province. Source intarissable de microrécits, d’anecdotes de « récits d’origine », cette vision fantasmagorique du territoire fait cohabiter la laideur avec la magie du territoire rural.
Le rock québécois débarque en France. À soir on fait peur au monde et Tabarnac, ou : le retour par le rockumentaire
Authors: Fillion Éric
Published: January 2024

Les rockumentaires À soir on fait peur au monde (François Brault et Jean Dansereau, 1969) et Tabarnac (Claude Faraldo, 1975) témoignent des possibilités d’expression collective engendrées par la rencontre du rock québécois et du cinéma. Ces deux longs métrages participent aux efforts accomplis par Robert Charlebois, Louise Forestier, le Rock libre du Québec et les musiciens d’Offenbach pour diffuser une image saisissante du Québec post-Révolution tranquille. Faraldo, Brault et Dansereau rendent audibles et visible — tout en les amplifiant par différentes stratégies représentationnelles — les procédés affectifs propres au rock québécois au moment où celui-ci s’impose en France. Ils contribuent ainsi à la constitution d’un répertoire émotionnel significatif autour duquel le public québécois est appelé à se rassembler. Le présent travail s’inspire des écrits d’Erin Hurley sur la mise en scène de la québécité tout en poursuivant les analyses du rockumentaire proposées entre autres par Keith Beattie et Michael B. Baker.
El Estado de Bienestar y la cuestión no resuelta de los cuidados. Propuestas hacia un modelo público-comunitario
Authors: Rius Buitrago Alicia , Salobral Martín Nieves
Published: January 2024

La crisis de los cuidados sigue siendo una cuestión crucial no resuelta en el Norte global a pesar de que muchos estados occidentales adoptaron modelos de bienestar, como destaca la economía feminista en su revisión de las políticas públicas. La implementación de políticas sociales, sanitarias y educativas se llevó a cabo de manera diferente en Europa, de hecho, en los países mediterráneos los trabajos de cuidados quedaron adscritos a los hogares y, dentro de estos, adjudicados a las mujeres. La corresponsabilidad social sigue siendo una utopía, a pesar de que la pandemia del Covid 19 mostró la cara más dura de la “crisis de los cuidados”, visibilizando que son las cuidadoras familiares o contratadas quienes se encargaban principalmente de proveer de cuidados materiales e inmateriales a las familias y personas con alguna dependencia. Sin embargo, ellas han recibido escaso apoyo por parte de las instituciones y las trabajadoras mantienen unas condiciones laborales muy precarizadas. En este contexto, la economía feminista y la economía social y solidaria han pensado estrategias dirigidas a la redistribución social y comunitaria de los cuidados.
Funerary sites during the Bell Beaker period in Galicia (Spain)
Authors: Prieto Martínez María Pilar
Published: January 2024

The Galician archaeological record presents certain problems for the preservation of most types of organic remains, so we must explain the past based on inorganic materials. In particular, the Bell Beaker communities have been explained almost exclusively by the presence of Bell Beaker ceramics, excluding all sites that do not contain this cultural element. This paper will present a summary of the sites classified as funerary in nature in Galicia. The depositional characteristics, the degree of fragmentation of the vessels, their position in the sites and the grave goods will be considered in terms of biographical reconstruction. The conclusion is that while only a few of the Bell Beakers had a truly funerary role, their more significant function was to facilitate the ritualised appropriation of Neolithic space as material symbols of a communal 'Bell Beaker' identity, as opposed to metal grave goods which designated individual status

La columna exenta como elemento religioso en el mundo ibérico (s.VI-I a.c.). revisión de testimonios iconográficos y arqueológicos
Authors: Robles Moreno Jesús
Published: January 2024

En el presente artículo se estudia la columna exenta como elemento religioso en el mundo ibérico a través de una revisión de la documentación iconográfica y los datos arqueológicos disponibles. De esta manera, se realiza una aproximación al significado y función del mismo en el mundo ibérico, señalando semejanzas y divergencias con el papel que desempeñó en el resto del Mediterráneo. La confrontación de datos iconográficos con los arqueológicos permite constatar una carencia de correlato arquitectónico, al menos hasta época tardía, de las numerosas escenas donde se incluye la columna. Esto conduce a una necesaria reflexión sobre la naturaleza del motivo y de su realia, la religión ibérica y sus espacios de culto. De ella se desprende que aunque la columna exenta siempre figuró en el imaginario religioso  ibérico, no se generalizó como elemento arquitectónico hasta la monumentalización de los santuarios desde el II a.C. en adelante
La necrópolis de la ampliación del Museo Nacional de Arte Romano (Mérida, Badajoz): estudio antropológico y contexto funerario
Authors: García Moreno Carlos David , López Costas Olalla , Murciano Calles José María , Sabio González Rafael
Published: January 2024

Presentamos el estudio de los esqueletos aparecidos en el solar del Museo Nacional de Arte Romano de Mérida. Abordamos la paleodemografía (mediante la estimación del sexo y edad), la cronología (mediante dataciones 14C en hueso) y la tafonomía, con especial atención a la preservación, comparándolo con el contexto funerario. El total de individuos identificados es de mínimo 118. El alto número de no-adultos (n=41) sugiere una elevada mortalidad infantil, coincidente con otras necrópolis coetáneas cercanas. Los restos están relativamente bien conservados, sin distribución diferencial por sexo/edad. La orientación predominante es SW-NE y fosa simple en decúbito supino. Trece enterramientos contenían clavos, ya sea por la presencia de caja de madera o pequeñas cajas a modo de ajuar. Las dataciones radiocarbónicas de dos tumbas aportaron una cronología bajoimperial-tardoantigua (ss. III-VI AD). Se observan similitudes entre todas las áreas funerarias de la Augusta Emerita, observándose un posible patrón del contexto funerario
Un ejemplo del luxus de los vasa murrina en Augusta Emerita
Authors: Cisneros Cunchillos Miguel , Encuentra Ortega Alfredo Pedro , Ortiz Palomar Esperanza , Paz Peralta Juan Ángel
Published: January 2024

El vaso en ágata de Augusta Emerita es un unicum. Las escasas informaciones relativas al contexto de su hallazgo y la excepcionalidad de la pieza han hecho que hasta ahora se aborde su estudio de forma parcial y especialmente desde el plano artístico, comparándose con otros ejemplares sobresalientes manufacturados en piedras preciosas. Quizá por ello se le ha asignado una cronología genérica, entre el s. I a.C. o en el I d.C. y un taller oriental sin concretar. En este trabajo revisamos el contenedor conservado en el Museo Arqueológico Nacional y efectuamos valoraciones sobre su manufacturación, funcionalidad, iconografía, cronología y lugar de fabricación, insertándolo en el significado de los uasa murrina y estableciendo paralelos con otros recipientes, elaborados en otras materias primas, indicativos de las relaciones entre artesanías en época romana. Con ello pretendemos abrir nuevas vías de investigación para su estudio y comprensión.

Authors: Pedon Nelson Rodrigo
Published: January 2024

Este livro, de Nelson Rodrigo Pedon, fruto do trabalho de diversos pesquisadores, faz uma análise dos movimentos sociais sob a perspectiva geográfica, com base na formulação de movimentos socioespaciais e movimentos socioterritoriais. Quando ainda era estudante de geografia, o pesquisador decidiu investigar a forma como os moradores de um bairro da periferia se organizavam para, em busca de soluções para os problemas locais, chamar a atenção do poder público. Ele então deu início à sistematização de ideias que o induziram a propor uma hipótese: nas relações de poder que os homens estabelecem entre si, o espaço adquire condição de território; dessa forma, a ação política de grande parte da classe trabalhadora envolve a conquista do espaço – e, portanto, a delimitação de seu poder manifestado na forma de território amplia suas capacidades, permitindo maior controle sobre os processos que condicionam suas vidas. A partir dessa formulação e de pesquisas sobre reivindicações populares junto a uma associação de moradores, o autor estabeleceu a relação entre topografia, condições de vida e participação política, imprescindível para que ele pudesse refletir sobre a importância da Geografia na compreensão dos processos sociais, cuja questão fundamental, ele afirma, é essencialmente territorial. “Esta obra pode ser considerada como um esforço de afirmação da identidade da ciência geográfica no conjunto das ciências humanas”, escreve Pedon.

Membrane contact sites (MCSs) are junctures that perform important roles including coordinating lipid metabolism. Previous studies have indicated that vacuolar fission/fusion processes are coupled with modifications in the membrane lipid composition. However, it has been still unclear whether MCS-mediated lipid metabolism controls the vacuolar morphology. Here we report that deletion of tricalbins (Tcb1, Tcb2, Tcb3), tethering proteins at endoplasmic reticulum (ER)-plasma membrane (PM) and ER-Golgi contact sites, alters fusion/fission dynamics and causes vacuolar fragmentation in the yeast
Saccharomyces cerevisiae
. In addition, we show that the sphingolipid precursor phytosphingosine accumulates in tricalbin-deleted cells, triggering the vacuolar division. Detachment of the nucleus vacuole junction (NVJ), an important contact site between the vacuole and the perinuclear ER, restored vacuolar morphology in both cells subjected to high exogenous phytosphingosine and Tcb3-deleted cells, supporting that phytosphingosine transport across the NVJ induces vacuole division. Thus, our results suggest that vacuolar morphology is maintained by MCSs through the metabolism of sphingolipids.
Cell autonomous role of leucine-rich repeat kinase in protection of dopaminergic neuron survival

Mutations in leucine-rich repeat kinase 2 (LRRK2) are the most common genetic cause of Parkinson’s disease (PD), which is the leading neurodegenerative movement disorder characterized by the progressive loss of dopaminergic (DA) neurons in the substantia nigra pars compacta (SNpc). However, whether LRRK2 mutations cause PD and degeneration of DA neurons
via
a toxic gain-of-function or a loss-of-function mechanism is unresolved and has pivotal implications for LRRK2-based PD therapies. In this study, we investigate whether LRRK2 and its functional homologue LRRK1 play an essential, intrinsic role in DA neuron survival through the development of DA neuron-specific
LRRK
conditional double knockout (cDKO) mice. We first generated and characterized floxed
LRRK1
and
LRRK2
mice and then confirmed that germline deletions of the floxed
LRRK1
and
LRRK2
alleles result in null mutations, as evidenced by the absence of
LRRK1
and
LRRK2
mRNA and protein in the respective homozygous deleted mutant mice. We further examined the specificity of Cre-mediated recombination driven by the
dopamine transporter
-
Cre
(
DAT-Cre
) knockin (KI) allele using a GFP reporter line and confirmed that
DAT-Cre
-mediated recombination is restricted to DA neurons in the SNpc. Crossing these validated floxed
LRRK1
and
LRRK2
mice with
DAT-Cre
KI mice, we then generated DA neuron-restricted
LRRK
cDKO mice and further showed that levels of LRRK1 and LRRK2 are reduced in dissected ventral midbrains of
LRRK
cDKO mice. While DA neuron-restricted
LRRK
cDKO mice of both sexes exhibit normal mortality and body weight, they develop age-dependent loss of DA neurons in the SNpc, as demonstrated by the progressive reduction of DA neurons in the SNpc of
LRRK
cDKO mice at the ages of 20 and 24 months but the unaffected number of DA neurons at the age of 15 months. Moreover, DA neurodegeneration is accompanied with increases of apoptosis and elevated microgliosis in the SNpc as well as decreases of DA terminals in the striatum, and is preceded by impaired motor coordination. Taken together, these findings provide the unequivocal evidence for the importance of LRRK in DA neurons and raise the possibility that LRRK2 mutations may impair its protection of DA neurons, leading to DA neurodegeneration in PD.
Diversity for commonality in the evolutionary changes of the reduced genome to regain the growth fitness

Published: January 2024

As the genome encodes the information crucial for cell growth, a sizeable genomic deficiency often causes a significant decrease in growth fitness. Whether and how the decreased growth fitness caused by genome reduction could be compensated by evolution was investigated here. Experimental evolution with an
Escherichia coli
strain carrying a reduced genome was conducted in multiple lineages for approximately 1,000 generations. The growth rate, which was largely declined due to genome reduction, was considerably recovered, associated with the improved carrying capacity. Genome mutations accumulated during evolution were significantly varied across the evolutionary lineages and were randomly localized on the reduced genome. Transcriptome reorganization showed a common evolutionary direction and conserved the chromosomal periodicity, regardless of highly diversified gene categories, regulons, and pathways enriched in the differentially expressed genes. Genome mutations and transcriptome reorganization caused by evolution, which were found to be dissimilar to those caused by genome reduction, must have followed divergent mechanisms in individual evolutionary lineages. Gene network reconstruction successfully identified three gene modules functionally differentiated, which were responsible for the evolutionary changes of the reduced genome in growth fitness, genome mutation, and gene expression, respectively. The diversity in evolutionary approaches improved the growth fitness associated with the homeostatic transcriptome architecture as if the evolutionary compensation for genome reduction was like all roads leading to Rome.
Pan-cortical 2-photon mesoscopic imaging and neurobehavioral alignment in awake, behaving mice
Authors: Vickers Evan D , McCormick David A
Published: January 2024

The flow of neural activity across the neocortex during active sensory discrimination is constrained by task-specific cognitive demands, movements, and internal states. During behavior, the brain appears to sample from a broad repertoire of activation motifs. Understanding how these patterns of local and global activity are selected in relation to both spontaneous and task-dependent behavior requires in-depth study of densely sampled activity at single neuron resolution across large regions of cortex. In a significant advance toward this goal, we developed procedures to record mesoscale 2-photon Ca2+ imaging data from two novel in vivo preparations that, between them, allow for simultaneous access to nearly all 0f the mouse dorsal and lateral neocortex. As a proof of principle, we aligned neural activity with both behavioral primitives and high-level motifs to reveal the existence of large populations of neurons that coordinated their activity across cortical areas with spontaneous changes in movement and/or arousal. The methods we detail here facilitate the identification and exploration of widespread, spatially heterogeneous neural ensembles whose activity is related to diverse aspects of behavior.

In the realm of medical imaging, the early detection of kidney issues, particularly renal cell hydronephrosis, holds immense importance. Traditionally, the identification of such conditions within ultrasound images has relied on manual analysis, a labor-intensive and error-prone process. However, in recent years, the emergence of deep learning-based algorithms has paved the way for automation in this domain. This study aims to harness the power of deep learning models to autonomously detect renal cell hydronephrosis in ultrasound images taken in close proximity to the kidneys. State-of-the-art architectures, including VGG16, ResNet50, InceptionV3, and the innovative Novel DCNN, were put to the test and subjected to rigorous comparisons. The performance of each model was meticulously evaluated, employing metrics such as F1 score, accuracy, precision, and recall. The results paint a compelling picture. The Novel DCNN model outshines its peers, boasting an impressive accuracy rate of 99.8%. In the same arena, InceptionV3 achieved a notable 90% accuracy, ResNet50 secured 89%, and VGG16 reached 85%. These outcomes underscore the Novel DCNN’s prowess in the realm of renal cell hydronephrosis detection within ultrasound images. Moreover, this study offers a detailed view of each model’s performance through confusion matrices, shedding light on their abilities to categorize true positives, true negatives, false positives, and false negatives. In this regard, the Novel DCNN model exhibits remarkable proficiency, minimizing both false positives and false negatives. In conclusion, this research underscores the Novel DCNN model’s supremacy in automating the detection of renal cell hydronephrosis in ultrasound images. With its exceptional accuracy and minimal error rates, this model stands as a promising tool for healthcare professionals, facilitating early-stage diagnosis and treatment. Furthermore, the model’s convergence rate and accuracy hold potential for enhancement through further exploration, including testing on larger and more diverse datasets and investigating diverse optimization strategies.
Teaching programming using eduScrum methodology
Authors: Voštinár Patrik
Published: January 2024

There are a large number of professions in the world today. Some professions are disappearing, and some new ones are emerging. However, they all have something in common: the need to manage them. Throughout its history, humanity has developed several constantly changing forms of management. For this reason, school absolvents must enter the labour market with skills already sufficiently developed, such as communication, cooperation, teamwork, responsibility, and the ability to plan their work. The article focuses on the issue of teaching programming through mobile applications and basic robotics through the innovative form of teaching-EduScrum. The EduScrum methodology is based on the agile software development method Scrum, which develops soft skills. The article describes our experience with this teaching in computer science classes. We established several hypotheses evaluated using descriptive statistics on a sample of 251 students. The main objective of the research is to verify whether teaching computer science in primary and secondary schools using the eduScrum methodology is more suitable than the classical-frontal teaching of computer science. The research showed that secondary school students preferred the eduScrum methodology more than traditional frontal teaching and the primary school students preferred traditional frontal teaching.
