La tentation mystique ? L’argumentation de La mort à Paris
Authors: Roullet Antoine
Published: November 2022

Ce chapitre s’intéresse à l’argumentation de Pierre Chaunu à l’heure de réfléchir au problème de la mort, abordé par lui d’une manière bien différente des autres historiens qui, dans les années 1960-1970, s’étaient confrontés au problème. Chaunu préserve une distance avec son objet, se méfie non sans contradiction de l’histoire intellectuelle de la mort, ne veut pas lui ôter son mystère, prend en compte les angoisses métaphysiques irréductibles qu’il suscite et cherche à saisir un « en-deçà » des mentalités, anthropologique, qui distingue clairement son travail de l’histoire des mentalités et de l’histoire française de la mort alors en vogue. Sa méthodologie, son usage des statistiques, la rhétorique chaunusienne et son goût du paradoxe, l’architecture de son ouvrage témoignent, plus que d’une communion avec l’historiographie de son temps, d’un dialogue avec la tradition mystique.
Pierre Chaunu, historien des Réformes. Note sur Église, culture et société (1981)
Authors: Szczech Nathalie
Published: November 2022

Cette contribution, lecture de l’ouvrage Église, culture et société que Pierre Chaunu a publié en 1981 pour les candidats à l’agrégation d’histoire, se propose de réfléchir à l’actualité de l’approche que l’historien proposait alors du temps des Réformes. Plutôt que d’écrire un manuel synthétique et lisse, Pierre Chaunu publie une série d’essais audacieux qui sont autant de fenêtres ouvertes sur un champ de recherche alors en plein renouvellement. Circulant librement dans la périodisation, l’espace et les catégories, il plaide pour une histoire désenclavée des Réformes, qui peut résonner auprès des historiens d’aujourd’hui. Attentif aux individus et non seulement aux collectifs, il initie les lecteurs à l’exploration de l’intériorité croyante, proposition dont on peut encore noter la pertinence. Ouvrant la voie aux travaux sur les affrontements religieux, qui ont renouvelé l’approche de la première modernité, Pierre Chaunu souligne l’importance de la conflictualité dans l’émergence de systèmes protestant et catholique qui se construisent comme nécessairement incompatibles et tragiquement rivaux.
Chaunu, historien de la paix ?
Authors: Hippler Thomas
Published: November 2022

La contribution analyse le traitement de la question de la paix dans l’œuvre de Pierre Chaunu. Une première partie essaie de comprendre l’absence de la thématique avant les années 1990. Une deuxième partie met la thématique de la paix en corrélation avec l’émergence des peace studies depuis les années 1950. Dans une troisième partie sont abordés les travaux de Chaunu sur la paix, depuis les deux grands colloques sur la question jusqu’à son tout dernier ouvrage, Leçons pour la paix, paru en 2006.
De la formation d’un concept à l’invention d’une tradition : les avatars de l’histoire sérielle
Authors: Müller Bertrand
Published: November 2022

L’histoire sérielle a été une notion et une proposition centrale en histoire et dans les sciences sociales dans les années 1960. Portée par Pierre Chaunu qui avait l’ambition d’en faire le programme rénovateur et fédérateur de la discipline, l’histoire sérielle n’est pas parvenue à s’imposer et a disparu des méthodes et du vocabulaire des historiens à partir des années 1970. Cette étude se propose d’examiner, à partir d’analyses lexicométriques et en s’inspirant de l’histoire sociale des concepts, comment Pierre Chaunu a tenté, en vain, d’imposer l’histoire sérielle comme une démarche scientifique puis l’a transformée et inscrite dans l’histoire de la discipline comme une tradition inventée..
Interviewer Pierre Chaunu
Authors: Laurentin Emmanuel
Published: November 2022

La réalisation de plus de cinq heures d’entretiens d’Emmanuel Laurentin avec Pierre Chaunu dans sa résidence caennaise en 2001 dura plus de trois jours. Son évocation permet de rappeler les relations complexes entre le journaliste d’histoire et l’historien devenu figure publique, d’en rappeler les principales étapes, les possibles contradictions et les nombreux paradoxes. La forme orale de l’entretien offre des moments d’échanges directs où ces éléments apparaissent clairement.
Pierre Chaunu, homo ego-historicus
Authors: Lacoue-Labarthe Isabelle
Published: November 2022

Quand on s’intéresse à l’histoire, plus encore à l’historiographie, et particulièrement à l’ego-histoire, Pierre Chaunu est incontournable : parce que c’est un récidiviste du retour sur sa propre histoire, sous des formes et des formats divers ; parce que ces textes, qui font écho aux thèmes qui traversent les travaux de l’historien (la mémoire, la mort, la foi, le temps) et révèlent l’étroite intrication entre la conception de la vie et l’œuvre de leur auteur, interrogent la possibilité d’une réelle étanchéité entre les deux ; parce que, enfin, cette manière de revenir sur son parcours personnel s’inscrit dans un mouvement d’ensemble, dont la publication des Essais d’ego-histoire (dirigée par Pierre Nora en 1987) est, à partir des années 1980, la manifestation la plus visible et l’un des embrayeurs, tout en présentant ses propres spécificités, au premier chef desquelles un souci de vérité, tant sur soi que sur l’histoire de l’humanité.
A possible lungfish burrow in the Upper Cretaceous Adamantina Formation (Bauru Basin, Brazil) and its paleoecological and paleoenvironmental significance

Published: November 2022

Vertebrates produce a variety of trace fossils, mostly tracks and trackways, coprolites, and burrows resulting from fossorial and subterranean habits. Burrows, particularly, tend to represent temporary or permanent shelter. Vertebrate burrows are relatively understudied in the Brazilian Mesozoic units, as well as in Cretaceous rocks worldwide. This study aims to analyze a paleoburrow in the Upper Cretaceous Adamantina Formation and to discuss its paleobiological and paleoenvironmental implications. A descriptive study was carried out on the paleoburrow morphology, following aspects such as orientation, architecture, and dimensions, and facies association analysis provided the interpretation of the paleoenvironment in which the tracemaker lived. The origin of the paleoburrow was highlighted, as well as the size of its possible producer, besides inferring the exposure time of the paleoburrow from taphonomic interpretations, which contains allochthonous bone remains. The results suggest long periods of dry conditions, as previously suggested for the much-debated Adamantina Formation, interrupted by flooding events as evidenced by facies analysis and suggested by the lungfish burrow. The possibility of a lungfish record also expands the presence of these animals to Adamantina Formation, even though more data are needed to understand the paleoecology of these formations. Keywords: lungfish, paleoburrow, floodplain, Adamantina Formation.

Published: November 2022

In this research, biostratigraphy of the Taleh Zang Formation, located in northern Lorestan, SW Iran, is discussed. The benthic foraminiferal contents of the upper Paleocene successions were examined in a carbonate platform setting in the context of European standard zonation (Shallow Benthic Zones). The co-occurrence of Glomalveolina levis (Hottinger) and Miscellanea miscella (d’Archiac & Haime) characterizes Zone SBZ 4, indicating a Thanetian age. Based on biofacies analysis and faunal associations, with emphasis on benthic foraminifera and coralline red algae, tidal flat and marginal marine environment exposed to salinity fluctuations (short-term salinity fluctuations or fully marine conditions), dominated by small benthic Foraminifera (Kathina) with slightly mesotrophic conditions, are determined for the deposition of the Poshte Jangal section. The highly translucent, shallowest part of the inner shelf dominated by representatives of Miscellanea and Opertorbitolites. The biotic assemblages representing warm tropical waters with oligotrophic conditions were observed in Palganeh and Pasan sections. Keywords: Taleh Zang Formation, Paleocene, Foraminifera, Biostratigraphy, Thanetian.
Biostratigraphy and paleoenvironmental significance of Paleogene foraminiferal assemblages from Dashte Zari area in High Zagros, West Iran
Authors: Babazadeh Seyed Ahmad , Cluzel Dominique
Published: November 2022

The Paleogene carbonate deposits of Pabdeh and Jahrum formations are widespread from the northwest (Dashte Zari area) to the southwest of the Shahrekord region in the High Zagros Mountains of Iran and record the lateral and upward transition from open marine into the shallow water environment. The Pabdeh Formation shows a succession of open marine pelagic and hemipelagic limestone, argillaceous limestone, and argillaceous chert. It consists of planktonic wackestone, pellet-planktonic wackestone, mudstone with planktonic foraminifera, and radiolarian siliceous wackestone, which accumulated within the Zagros Foreland Basin. The planktonic foraminifers are assigned to the Late Paleocene–Late Eocene and correspond to subtropical and tropical Zones P4b–E15. The Jahrum Formation is represented by bioclast-bearing limestone and calcarenite. It consists of benthic foraminiferal wackestone, benthic foraminiferal-red algal packstone, and bioclast-intraclast packstone deposited in a shallow platform environment. The Jahrum Formation is inter-fingered in the upper part of the Pabdeh Formation and finally overlies it conformably during the Bartonian–Priabonian. Shallowing and off-lap relationships record basin shrinking, while repeated inter-fingering signals moderate tectonic subsidence. Both formations are disconformably covered by the Late Oligocene–Miocene Asmari Formation. Keywords: biostratigraphy, Pabdeh Formation, Zagros, Paleogene, Iran.

Photogrammetry of an excavated ichnofossil by giant sloths (Megaichnus major). During the Pliocene and Pleistocene, the extinct giant mammals that lived in South America had the burrowing behavior that, in the search for shelter and refuge, produced large ichnofossils called Megaichnus (paleoburrows). Megaichnus are biogenic structures in the form of tunnels and halls excavated by Folivora (Megaichnus major) and Cingulata (Megaichnus minor). On the ceiling and walls of these paleoburrows, it is possible to observe traces of excavation of these animals. Photogrammetry was performed by imaging M. major to generate the Three-Dimensional Digital Model (3DM). The paleoburrow is located in the Municipality of Doutor Pedrinho (Santa Catarina State) and was excavated in the sandstone of the Taciba Formation (Permian). The photographs were processed to generate the 3DM and the virtual reality interface with 3D glasses. The 3DMs are available for viewing on the Sketchfab website through the links (GoPro 4; https://skfb.ly/6RYyn) and (Nikon D60; https://skfb.ly/ooprJ). 3DM allows easy access to the ichnofossils, making it possible to study them remotely from anywhere in the world. The construction of 3DMs of the paleoburrows, through high-resolution photogrammetry, is an innovative proposal, and allows wide dissemination of knowledge about these structures. Keywords: paleoburrows, Quaternary, megafauna, 3D imaging.
Interpretação paleoclimática com base na análise da fisionomia foliar de duas floras pleistocênicas, Formação Rio Claro, São Paulo, Brasil
Authors: Santiago Francisco , Jurigan Isabela , Ricardi-Branco Fresia
Published: November 2022

Paleoclimatic interpretation based on the analysis of the leaf physiognomy of two Pleistocene floras, Rio Claro Formation, São Paulo, Brazil. The Jaguariúna and Jazigo Vargem Grande do Sul fossil floras are well-preserved records of an ancestor of one of the phytophysiognomies of the Atlantic Forest, the oldest belt of tropical forest in the world. These fossil floras are associated with the Rio Claro Formation, one of the most important sedimentary records of the Pleistocene from the São Paulo State Peripheral Depression, Brazil. The main physiognomic characteristics–type of margins and leaf area – of the angiosperm leaves from these floras allowed us to carry out the reconstruction of the mean annual temperature (MAT) and the mean annual precipitation (MAP) for the moment of their deposition. The different equations used to reconstruct the MAT and the MAP are based on univariate methods known as Leaf Margin Analysis and Leaf Area Analysis. These equations indicated that the warm and humid subtropical/tropical climate under which the Jaguariúna fossil flora developed was characterized by a MAT of 22.1–22.8°C and a MAP of 566–831 mm, and also that the warm and humid subtropical climate under which the Jazigo Vargem Grande do Sul fossil flora developed was characterized by a MAT of 24.6–25.1°C and a MAP of 747–961 mm. These values indicate that, at the moment of deposition of the fossil floras of Jaguariúna and Jazigo Vargem Grande do Sul, conditions were warmer and less humid than the current ones. Therefore, it is possible to infer that these floras developed in a smaller climatic cycle, the interglacial period, during which the Rio Claro Formation was deposited. Keywords: Atlantic Forest, Pleistocene, physiognomic characteristics, angiosperm leaves, climatic cycle, interglacial period.

Published: November 2022

A set of microbiologically induced corrosion was carried out on different types of carbon steels: AISI 1006 and API 5L X52, iron-oxidizing bacterium and sulfur-oxidizing bacterium, a mixed culture of Alicyclobacillus ferrooxydans SKC/SAA-2 and Aspergillus niger and Comamonas thiooxydans SKC/SAA-1, in the presence of the corrosion-inhibiting bacterium, Pseudomonas plecoglossicida. According to the immersion test experiments, weight loss of API 5L X52 was lower (0.06-0.27%) than AISI 1006 (0.14-0.32%). AISI 1006 showed more detrimental localized pitting corrosion than API 5L X52. During the longer incubation time, the corrosion-inhibiting bacterium was more homogenous and compact, which affected the specimen surface more protective characteristics. The 2-week-old biofilm effectively protected the API 5L X52, as indicated by the low amount and more negligible pitting corrosion. This study will be the first report on the biocorrosion behaviour of carbon steels using different corrosion-causing microbes in the presence of the corrosion-inhibiting bacterium.

Published: November 2022

Colon cancer or colorectal cancer is one of the major health problems in the world. Previous research has proven that red betel leaves extract has anticancer activity against breast cancer cells. The study aimed to look at the potential of compounds contained in red betel ethyl acetate fraction as anticancer substances for colon cancer by conducting in silico tests through the docking of three colon cancer biomarker receptors against eight red betel leaves compounds. The parameters of binding affinity energy and inhibition constant used in the molecular docking analysis showed that there are several compounds that have the potential as inhibitors against colon cancer marker proteins to inhibit the development of colorectal cancer and have high bioavalibility as oral drugs. Based on in silico test it is known that the compound N-1,N-9-Bis [E-(2-nitophenyl) methylene] non anedihydrazide has the highest inhibition of human leukotriene A4 hydrolase receptor with binding affinity energy of 11.3160 Kcal/mol. The next compound is 4-({4,6-Bis[3R,5S)-3,5-diamino-1-piperydinyl]-1,3,5-traizin-2-yl}amino) benzenosulfon amide which has the highest inhibition in Chek1 with binding affinity energy of 9.7110 Kcal/mol, and the compound 4-(4-methoxy-phenylamino)-2,3-dihydro-1H-4a, 9-diaza-cyclopenta (b) fluorine-10-carbonitrile has the highest inhibition in the Bcl 2 navitoclax analog receptor with binding affinity energy of 8.4470 Kcal/mol.

Published: November 2022

The levels of rosmarinic acid and sinensetin in purple and white-purple varieties of Orthosiphon aristatus, cat's whiskers, can be increased using modified in vitro culture. This work focused on callus induction of the purple and white-purple variety of cat's whiskers grown on Gamborg (B5) and CHU (N6) with the addition of growth regulators 2,4-dichlorophenoxyacetis acid. Our observation suggested that the callus could grow within three weeks and produce rosmarinic acid and sinensetin. The level of sinensetin from various extraction methods is relatively low; in contrast, the rosmarinic acid from purple callus was detected at about 5% w/w, while the white-purple variety was around 2% w/w. The results of this study also provided new information on the basic media other than MS that can grow cat's whiskers callus while producing active compounds.

Published: November 2022

Tobacco armyworm (Spodoptera litura Fab.) is one of the major insect pests of crops in Indonesia. The management of this pest still depends on the use of chemical insecticides. The use of bio-insecticides, such as Bacillus thuringiensis (Bt.), are known to be alternatives, but it easily degraded by sunlight. This research aimed to study the eﬀects of UV B on Bt. pathogenicity and to explore plant-based additives as UV B protectants for Bt. against armyworm. Thirteen plant extracts were screened based on their UV spectra absorbencies using UV spectrophotometry. The extracts, namely cloves, Jicama, Celebes pepper, turmeric, and Moringa, then used for the formulations of Bt. and exposed under UV B lights for 0, 72, and 144 h. After exposure to UV B, Bt. formulations were tested for bioassay against one- day-old 1st and one day old 2nd larval instars of tobacco armyworm. The result indicated that at 72 and 144 h of UV B exposures, the Bt. added formulations were signifcantly diﬀerent compared to Bt. alone. At 72 h exposure against the 2nd larval instar, the larval mortality of tobacco armyworm on the second day of observation on Bt. formulated with Celebes pepper and turmeric was 97.3 and 80%, respectively, whereas, at 144 h exposure, the mortality was 96 and 89.3%, respectively. This study concluded that Celebes pepper and turmeric extracts were the potential to be used as the Bt. protectants against UV B.
Physiological Characteristics to Indicate Water Use Efficiency and Drought Tolerance of 30 Indonesian Sorghum [Sorghum bicolor (L.) Moench] Accessions
Authors: Widiyono Wahyu , Nugroho Satya
Published: November 2022

Water use efficiency (WUE) is an essential subject in drought-restricted agricultures. Physiological parameters can be used to understand plant efficiencies in water usage. This research aimed to understand the physiological characteristics of 30 Indonesian sorghum accessions (Sorghum bicolor (L.) Moench), which indicate WUE and drought tolerance. Field research was conducted at Cibinong Science Center, National Research and Innovation Agency (BRIN) using Randomized Block Design with 30 sorghum accessions in 3 replicates. Experimental parameters included photosynthetic photon flux density (PPFD), stomatal conductance (GSW), photosynthetic (A) and transpiration (E) rates, and Leaf Area Index (LAI). The WUE was measured using four different approaches: instantaneous WUE (A:E), intrinsic WUE (A:GSW), and the relation between the biomass dry weight (BDW)/A and BDW/E. Based on WUE measurements, we concluded that sorghum accessions could be clustered into five groups, from the most efficient to inefficient water use. We also found that in some cases, WUE based on single leaf measurement had a positive correlation with WUE based on biomass, indicating its sufficiency in determining WUE status. The inconsistencies may be due to different sorghum physiological characteristics regarding gas exchange due to external stimuli (PPFD).

The exosome is a nano-sized vesicular particle commonly secreted from eukaryotic cells to extracellular space. Exosome functions in cellular communication, nutrients or bioactive compounds delivery, and cellular immunity. It is believed that plant-derived exosome-like particle (PDEN) potential to deliver nano-bioactive compounds to the human body. As Indonesia is one of the herbal centers of the world, we are encouraged to develop natural richness for human welfare. The study aimed to verify various methods to isolate exosomes from the fresh ginger rhizome and quina cells and examine the ginger PDENs' capacity to internalize in vitro human cells. The PDENs isolation was carried out by centrifugation and precipitation. The particles were observed through a transmission electron microscope, dynamic light scattering, and particle size analysis. Differential ultracentrifugation combined with PEG6000 provided a better size range of particles. Nanoparticles tracking analysis performed the concentration of particles within a specific size range. Ginger and quina PDENs size ranged from 40-650 nm, and the concentration was 3.6 × 107 and 2.8 × 106, respectively. The PKH67-labelled ginger PDENs were taken up by human dermal fibroblast and human Wharton's jelly mesenchymal stem cells after 30 minutes and 21 hours. DPPH assays revealed that ginger PDENs have antioxidant activity, indicating the presence of some nano-molecules in those particles. This study would be the baseline for developing ginger PDENs as a functional food with nano-ingredients, or as an effective vehicle of nano-drug, for human health.

Authors: Ramayanti Indri , Herlinda Siti , Muslim Ahmad , Hasyim Hamzah
Published: November 2022

Fungi from South Sumatra (Indonesia) were identified morphologically and molecularly, and their pathogenicity to egg, larvae, and adult Aedes aegypti was evaluated. The fungal isolates used for bioassay were 11 isolates from this study and 4 isolates from the laboratory collection. Fifteen isolates of five fungal species (Metarhizium anisopliae, Penicillium citrinum, Talaromyces diversus, Beauveria bassiana, and Purpureocillium lilacinum) from South Sumatra, Indonesia, were pathogenic to the egg, larvae, and adult of Ae. aegypti. Egg mortality caused by M. anisopliae isolate MSwTp3 was the highest (38.31%). A novel finding of this study was that the eggs exposed to the fungus not only killed the eggs but could continue to kill the emerging larvae, pupae, and adults. The five fungal species induced larval mortality between 52.22−94.44% and adult mortality between 50.00−92.22%. Fungal strains belonging to M. anisopliae, P. citrinum, T. diversus, and B. bassiana from South Sumatra seem to possess remarkable ovicidal, larvicidal and adulticidal activity against Ae. aegypti. M. anisopliae, P. citrinum, T. diversus, and B. bassiana had the potential as entomopathogens to be developed into ovicides, larvicides, and adulticides for controlling Ae. aegypti.

Published: November 2022

This research presents the unusual staining characteristic of the teleosts red blood cells–the common bluestripe snapper Lutjanus kasmira, caught at Toc Tan (Allison) Reef, Truong Sa Archipelago, Vietnam, due to side effects of the delayed staining procedure. In addition to the quantitative data measured, the results of microscopic image research showed that, on slides performed with the delayed Romanovsky staining procedure using Giemsa dye, the cell "nucleus" was not dye-stained as seen in the erythrocytes of much other fish. The AFM and SEM images of blood slides show that the structure of the nuclear zone and the nuclear membrane was destroyed. Although methanol is used as one of the common fixatives in biology, the delayed staining still causes artifactual side effects, disrupts the structure of the red blood cell nucleus and can cause confusion when studying cytogenetics.

Published: November 2022

This study was aimed to confirms the Banana Bunchy Top Virus (BBTV) infection of ten banana accessions from Indonesia through PCR assay using primer of BBTV coat protein (CP) gene, also the sequences characteristics and phylogeny. Preliminary morphological results showed five acessions were positively infected with slight to severe intensity symptoms i.e. Pisang Berlin, Candi, Billa, Morosebo, and Mas Kripik; and five accessions were symptomless i.e. M. acuminata var. rutilifes and M. balbisiana, Pisang Ebung, Madu and Moseng. However, PCR results qualitatively confirms that all accessions were positively infected. Two sizes of amplicons were identified. Pisang Candi isolate was showing ±500 bp amplicons, whereas the others were ±1000-1100 bp. The total aligned and selected BBTV CP sequences of 36 accessions (bananas and other host species) was 450 nt. It was considered highly conserved (85.55%), low G+C content (41%), and high genetic similarities (92.47 to 100%). Phylogenetic analysis delineates isolates into two large groups, i.e. the Asian group (East Asia and South-east Asia) and the South Pacific group (South Asia, Africa and the Pacific). The findings of this study are usefull for broader applicability of further banana breeding program particularly for mitigation, selection and evaluation of banana with BBTV resistance.

Published: November 2022

Probiotics are widely consumed in various food matrices to provide health benefits to the host. The viability of probiotic cells is influenced by several factors, including exposure to high temperatures during the production process and low temperatures during storage. In this study, we report the response to cold stress of Lantiplantibacillus plantarum subsp. plantarum Mut-3 and Mut-7 after 24 h of storage at 4°C and -20℃. The cell number of Lantiplantibacillus plantarum subsp. plantarum Mut-3 and Mut-7 in low-temperature condition had no significant differences than their initial number: 11.88 log CFU/ml and 11.62 log CFU/ml at 4°C; 11.51 log CFU/ml and 11.47 log CFU/ml at -20°C for Mut-3 and Mut-7 respectively. The results indicated the survival capacity of Lantiplantibacillus plantarum subsp. plantarum Mut-3 and Mut-7 at low temperatures. The genes encoding cold shock proteins for the response to cold stress were evaluated by genome sequencing. The CspA/CspC genes of Lantiplantibacillus plantarum subsp. plantarum Mut-3 and Mut-7 possibly play a role in maintaining cell resistance at low temperatures, since the genes products predicted to have conserved motifs in the RNA binding protein (RNP) -1 and RNP-2 responsible for cold response stress which are similar to those in other bacteria.

Published: November 2022

This study aimed to obtain a functional lipase (LipRM) from Ralstonia pickettii BK6 through a co-expression involving its foldase. The ORF of the LipRM was 999 bp while the gene encoding of lipase-specific foldase (LifRM) was 1,030 bp. LipRM and LifRM genes were cloned into a plasmid and were successfully co-expressed in Escherichia coli strains to produce functional LipRM. Enzyme activity from partially purified enzymes showed quite surprising results, LipRM activity in E. coli BL21 (DE3) was 25.84 U/ml, while the other strains (DH5α, HB101, S17-1λpir) were 628.98 U/ml, 761 U/ml, and 1206.46 U/ml, respectively. The highest relative activity of LipRM was found at 50-55°C and pH 7-8 with pNP-laurate (C12) as the preferred substrate specificity. LipRM activity was enhanced sharply in the presence of 30% organic solvents (methanol and ethanol) but decreased by more than 50% in the presence of detergents. This study was the first to report heterologous expression of Ralstonia pickettii lipase employing its native foldase resulting in functional lipase from subfamily I.2.

This study aimed to evaluate the effects of ciplukan (Physalis angulata L.) leaf ethanol extract on L-NG-nitroarginine methyl ester (L-NAME)-induced hypertensive rats. We randomly divided twenty-five Wistar rats into five groups. The sham group was given a PBS injection. The hypertensive group was injected with L-NAME on days 1 to 28. Three groups of hypertensive rats were given the extract on days 4 to 28. Blood pressure was measured using the tail-cuff method on days 0, 4, 10, and 27. The endothelial progenitor cells (EPCs) in the blood were measured by flow cytometry as a percentage of circulating angiogenic cells (CACs, CD34+/CD309+/CD45+) and endothelial colony-forming cells (ECFCs, CD34+/CD309+/CD45-). Serum NO and MDA levels, as well as serum SOD activity, were measured colorimetrically. Serum TNF-α levels were measured by the ELISA method. The ciplukan leaf extract reduced systolic and diastolic blood pressure, reduced the percentage of EPCs in the blood, increased serum NO levels, reduced MDA levels, increased serum SOD activity, and reduced serum TNF-α levels in L-NAME-induced hypertensive rats. It is concluded that ciplukan ethanol leaf extract exerts protective effects on L-NAME-induced hypertensive rats. These study results can strengthen the scientific basis of using ciplukan leaf ethanol extract to treat hypertension.

Published: November 2022

Stress is a process that involves the perception of and response to pressure and is often related to eating behaviour. For college students, academic stress could be one factor that affects eating behaviour. So far, no longitudinal study has directly compared the same respondents’ stress levels and eating behaviours in different years of study. Thus, this study aimed to examine changes in stress levels and eating behaviour during college students’ third and final years and determine the correlation between stress levels and eating behaviour. We asked 89 undergraduate students (27 males and 62 females) to complete a questionnaire on their stress levels using the Perceived Stress Scale (PSS-10) and their eating behaviour. Our results showed that students had significantly higher stress levels during the final year than in their third year. Our results also showed that during the student’s final year, there was a significant increase in eating when feeling stressed, overeating, eating fast food, and skipping meals compared to their third year. There was also a significant decrease in healthy food consumption during the final year compared to the third year. During the third year of study, stress levels were increased by academic workload pressure; meanwhile, during the final year of study, they were affected by sex and undergraduate thesis pressure. These results indicate that differences in academic pressure in different years of study can influence stress levels and eating behaviour in college students.

The oyster mushroom (Pleurotus ostreatus) is the most cultivated mushroom which its growth performance and nutritional composition depend on substrate types. Thus, this study investigated the effect of coconut coir on minerals and vitamins B contents in the oyster mushroom cultivation medium. The composition of coconut coir and Sengon’s sawdust as growth medium were variated at ratios of 4:0 (F1), 3:1 (F2), 2:2 (F3), 1:3 (F4), 0:4 (F5) (w/w). Furthermore, the mineral and vitamin B contents of the harvested oyster mushrooms were analyzed by ICPMS and LCMS, respectively. The highest minerals contents of potassium 26,909 mg/kg, 1,136 mg/kg of phosphorus, 313 mg/kg of magnesium, 4,346 mg/kg of calcium, 15.4 mg/kg for zinc, 2.07 mg/kg of copper, 0.623 mg/kg of Selenium were identified at F1, whereas the highest manganese was at F2 (15.3 mg/kg). Potassium was the highest mineral content in oyster mushrooms in all growth media, and low toxic minerals content of cadmium was detected between 0.015-0.058 mg/kg in all variant substrates. Lead (0.525 mg/kg) and mercury (0.012 mg/kg) was only detected at F1, while arsenic was detected at F4 (0.002 mg/kg) and F5 (0.029 mg/kg). LCMS analysis showed that vitamin B1 (Thiamine), B3 (niacin), B6 (pyridoxine) and B12 (cyanocobalamin) were detected in all growth media, while vitamin B5 (pantothenic acid) was only detected at F5. These results indicated that the P. ostreatus cultivation on coconut coir become valuable nutritional resources to alleviate malnutrition and help dispose of coconut coir in an environment-friendly manner.
La comunicación científica: Proceso que exige ir más allá de acercar un cumulo de conocimientos
Authors: Vargas Cesar
Published: November 2022

Nuestra sociedad se encuentra inevitablemente inmersa en la dinámica mundial que conduce de manera compleja hacia la denominada Sociedad del Conocimiento, en la cual se observa una aceleración sin precedentes del ritmo de creación, acumulación, sin duda también de depreciación del conocimiento, sumado a una representación cada vez más importante de la comunicación científica como catalizador de nuevos procesos de investigación académica y vía para dar a conocer los avances en las distintas disciplinas del saber. Asimismo, la comunicación vivifica la ciencia y es uno de los principales vehículos hacia la prosperidad, siendo siempre sinónimo de progreso económico y social. Un nuevo conocimiento, una nueva información producto de la ciencia que no llega a sus destinatarios, no merece el nombre de información. Con base a estas consideraciones el siguiente ensayo tiene como propósito hacer una disertación en torno a la comunicación científica y la demanda social de la mismos en la generación de nuevos conocimientos

Garantizar que la sociedad de la información se base en el principio del respeto mutuo y en el cumplimiento de los derechos humanos es uno de los mayores desafíos éticos del siglo XXI. Además de los beneficios que aporta, un mundo conectado digitalmente también conlleva una serie de peligros y amenazas derivados del uso indebido de las TIC. Este ensayo, nace como parte del proceso de formación en el curso proyecto investigativo de la carrera de Educación en Lenguas Extranjeras Mención Inglés de la Universidad Francisco de Miranda, todo ello con el propósito de generar en el estudiante reflexiones criticas ante el tema de la ética no solo como un aspecto académico sino también como constructo de la moral que involucra todas las acciones humanas.
THE AMAZONIAN Arapaima CHANGES ITS STATUS FROM THREATENED SPECIES TO AN INVADER OF EARTH’S FRESHWATER ECOSYSTEMS

Published: November 2022

A survey of the records was conducted regarding the locations on the planet in which Arapaima has been introduced from its natural habitats in areas of South America, whether for aquaculture or the aquarium trade. Originally, the global expansion of this species was intended to maintain its existence in the face of a perceived risk of extinction. However, the results of the intended and accidental spread of its distribution reveal that Arapaima is an invasive species that can endanger native fish species diversity. It is an air breather, which allows it to inhabit low oxygen conditions of warm tropical water, and a species that grows fast, attaining a large size when mature. It also presents parental care and is a generalist predator that feeds on many other species. Furthermore, it can escape from managed fish farms into natural waterways and establish viable populations without control. From the literature, 228 sites with records of Arapaima from around the world were identified, 95 of which are native sites for the species and 133 are sites where they were introduced. These sites are distributed in 28 countries in the Americas (North, Central and South), Europe, and Asia. Published results of introductions reveal that Arapaima has had negative impacts on native fish species, thus warranting closer attention in regards to how, when and where this species should be allowed.

Regardless of the profile of the enterprise, in the process of activity, the formation of its income always occurs. It is this aspect of the activity that is most important for all stakeholders - the owners of the enterprise, employees, the state, since the successful formation and proper distribution of income allows all participants in production activities to ultimately achieve their financial goals - primarily increasing welfare and quality of life, making a profit. Income is the primary incentive to create new or develop existing enterprises. The opportunity to make a profit encourages people to look for more efficient ways to combine resources, to invent new products that may be in demand, to apply organizational and technical innovations that promise to increase production efficiency. Working profitably, each enterprise contributes to the economic development of society, contributes to the creation and enhancement of social wealth and the growth of the well-being of the people.
