Type 2 diabetes mellitus (T2DM) is associated with higher severity and mortality in SARS-CoV-2 infections. Vaccination has been encouraged to boost immunity and prevent these unfortunate outcomes. Few studies have evaluated antibody levels after COVID-19 vaccination in patients with T2DM. Therefore, we examined the vaccination status and anti-SARS-CoV-2 antibody levels to identify the factors that affect the antibody levels in patients with T2DM. This cross-sectional study was conducted at the Dr. Hasan Sadikin Hospital and Bandung Kiwari Hospital, Bandung, West Java, Indonesia, between October and November 2022. Adult participants with and without T2DM were tested for SARS-CoV-2 antibodies using a point-of-care quantitative immunochromatographic assay. We enrolled 289 participants: 201 participants with T2DM and 88 participants without T2DM. The T2DM participants had a lower vaccination rate compared with the non-T2DM participants. However, no significant differences in antibody levels were observed between the two groups. Higher antibody levels among the T2DM participants were associated with mRNA vaccination and a history of COVID-19 illness. The lower antibody response observed among the T2DM participants with chronic obstructive pulmonary disease suggests that such patients may need antibody level measurement and an additional booster vaccine.

Hemodialysis patients faced an excess morbidity and mortality during the COVID-19 pandemic. We evaluated the effect of second-generation mRNA vaccines against Omicron BA.4 and BA.5 variants of SARS-CoV-2 on humoral immunity. The study population comprised 66 adult hemodialysis patients who have encountered four SARS-CoV-2 antigen contacts through vaccination or infection. We assessed their humoral response using an anti-SARS-CoV-2 spike receptor binding domain IgG antibody assay (S-RBD-ab), measuring neutralizing antibodies against ancestral strain of SARS-CoV-2, Delta, and Omicron in a surrogate virus neutralization test (SVNT), and specifically against BA.5 in a plaque reduction neutralization test (PRNT) before and four weeks after vaccination with Comirnaty Original/Omicron BA.4-5. During the following six months, SARS-CoV-2 infections and symptom severity were documented. The bivalent mRNA vaccine led to a 7.6-fold increase in S-RBD-ab levels and an augmented inhibition of the Omicron variant in SVNT by 35% (median). Seroconversion in the Omicron BA.5-specific PRNT was attained by in 78.4% of previously negative patients (29/37). Levels of S-RBD-ab correlated with inhibition in the Omicron-specific SVNT and neutralization titers in the BA.5-PRNT. Eleven SARS-CoV-2 infections occurred in the six-month follow-up, none of which took a life-threatening course. The bivalent mRNA vaccine improved the SARS-CoV-2 virus variant-specific humoral immunity in chronic hemodialysis patients. Measurement of S-RBD-ab can be used in hemodialysis patients to estimate their humoral immunity status against Omicron BA.5.

Cell types have been established during organogenesis based on early mouse embryos. However, our understanding of cell types and molecular mechanisms in the early embryo development of Mongolian sheep has been hampered. This study presents the first comprehensive single-cell transcriptomic characterization at E16 in Ujumqin sheep and Hulunbuir short-tailed sheep. Thirteen major cell types were identified at E16 in Ujumqin sheep, and eight major cell types were identified at E16 in Hulunbuir short-tailed sheep. Function enrichment analysis showed that several pathways were significantly enriched in the TGF-beta signaling pathway, the Hippo signaling pathway, the platelet activation pathway, the riboflavin metabolism pathway, the Wnt signaling pathway, regulation of the actin cytoskeleton, and the insulin signaling pathway in the notochord cluster. Glutathione metabolism, glyoxylate, and dicarboxylate metabolism, the citrate cycle, thyroid hormone synthesis, pyruvate metabolism, cysteine and methionine metabolism, thermogenesis, and the VEGF signaling pathway were significantly enriched in the spinal cord cluster. Steroid biosynthesis, riboflavin metabolism, the cell cycle, the Hippo signaling pathway, the Hedgehog signaling pathway, the FoxO signaling pathway, the JAK-STAT signaling pathway, and the Wnt signaling pathway were significantly enriched in the paraxial mesoderm cluster. The notochord cluster, spinal cord cluster, and paraxial mesoderm cluster were found to be highly associated with tail development. Pseudo-time analysis demonstrated that the mesenchyme can translate to the notochord in Ujumqin sheep. Molecular assays revealed that the Hippo signaling pathway was enriched in Ujumqin sheep. This comprehensive single-cell map revealed previously unrecognized signaling pathways that will further our understanding of the mechanism of short-tailed sheep formation.

Изучено влияние однонуклеотидных полиморфизмов (SNP) в генах стеароил-КоА-десатуразы (SCD) и FABP4, ответственных за регуляцию внутриклеточного белка, связывающего жирные кислоты (FABP4). Эти гены ассоциированы с уровнем и свойствами жирнокислотного состава в организме коров, а также влияют на формирование продуктивных качеств у мясного скота. Целью работы было изучение полиморфизмов генов SCD и FABP4 и их влияния на живую массу у бычков калмыцкой породы. Исследования проводили в Ставропольском крае. Объектом изучения являлись бычки (n=156) в возрасте 8 мес. Установлено, что животные — носители более распространенного гетерозиготного ТС-генотипа в замене T878C (p.Ala293Val., 26:21272422, rs41255693) в гене SCD имели более высокую живую массу по сравнению с носителями гомозиготных вариантов TT- и СС-генотипов на 2,5 и 17% соответственно, а также среди всего исследованного поголовья по двум изучаемым генам. Животные, носители гомозиготного АА-генотипа замены c.408A>G в гене FABP4, имели наибольшую живую массу среди всех исследованных особей по этому гену, при этом носители AG-генотипа отличались наименьшей массой. Изученные полиморфизмы генов SCD и FABP4 имеют высокую достоверную связь с живой массой у бычков калмыцкой породы и могут быть использованы в качестве ДНК-маркеров в селекции калмыцкой породы крупного рогатого скота.

The influence of single nucleotide polymorphisms (SNPs) in the stearoyl-CoA desaturase SCD and FABP4 genes responsible for the regulation of intracellular fatty acid-binding protein (FABP4) was studied. These genes are associated with the level and properties of the fatty acid composition in the body of cows, and also affect the formation of productive qualities in beef cattle. The aim of the work was to study the polymorphisms of the SCD and FABP4 genes and their effect on live weight in Kalmyk bulls. The research was carried out in the Stavropol Territory. The object of the study were bulls (n=156) at the age of 8 months. It was found that animals carrying the more common heterozygous TC genotype in the T878C substitution (p.Ala293Val., 26:21272422, rs41255693) in the SCD gene had a higher body weight compared to carriers of homozygous variants of the TT and CC genotypes by 2. 5 and 17%, respectively, as well as among the entire population studied for the two studied genes. Animals carrying the homozygous AA genotype of the c.408A>G substitution in the FABP4 gene had the highest body weight among all the studied individuals for this gene, while the carriers of the AG genotype were distinguished by the smallest weight. The studied polymorphisms of the SCD and FABP4 genes have a highly significant relationship with live weight in Kalmyk bulls and can be used as DNA markers in Kalmyk cattle breeding.

Déraisonner avec ou sans la raison. Analyse du chapitre XV du Traité théologico-politique
Authors: Lagrée Jacqueline
Published: August 2023

Une analyse fouillée du chapitre XV du T.T.R rapproché du ch. XI de l'Interpres de L. Meyer montre comment Spinoza renvoie dos à dos les sceptiques et les dogmatiques qui s'affrontent sur le sens spéculatif de l'Écriture. Par le biais de la réfutation d'Alpakhar, Spinoza se démarque dans le procédé comme dans le détail de sa critique, du principe herméneutique de son ami L. Meyer, excluant, comme deux délires antagonistes, la récusation de la raison et l'attribution à la raison d'un empire absolu, exclusif d'autres modes d'appréhension du réel, en l'occurrence ici de ce que nous dit aujourd'hui encore l'Écriture Sainte.

Le cynisme des cyniques
Authors: Chauve Alain
Published: August 2023

The cynicism of Antiquity forms a real philosophy. In cynicism people saw the means of making themselves ferocious, or showing an ascetic will for austerity, for destitution or for the denigration of social values. But cynicism should first by understood as a relation to truth, imposed by the logical rigour of identity. This relation to truth makes it possible for the cynic to be lucid, but it also marks the limits of this lucidity.
La théorie épicurienne du rêve
Authors: Droz-Vincent Gabriel
Published: August 2023

Le phénomène du rêve résiste à la mise en forme systématique de l'expérience selon les principes d'Epicure que tente Lucrèce. L'explication à laquelle il se tient — basée sur la continuité entre la vie éveillée et le rêve — reste délibérément au niveau de ce que Freud appellera le «contenu manifeste» des rêves. Le refus que le rêve puisse transmettre un message de l'au-delà, sinon de l'inconscient, lui interdit d'aller plus loin dans l'explication. Un type particulier de rêve — celui où les Dieus se présentent à nous — pose problème à cette explication «cinématographique» du rêve par la succession plus ou moins rapide des simulacres : les Dieux peuvent-ils être simplement connus par les simulacres qu'ils émettent ou leurs attributs propres (béatitude, éternité) nous sont-ils donnés par l’esprit ?
Le Socrate malsain de l'Assemblée Nationale : Burke et Rousseau
Authors: Thierry Patrick
Published: August 2023

Burke wird sich (seltsamerweise für ihn selbst und für seinen Leser) in die Nähe Rousseaus gestellt sehen, den er ansonsten zum Verantwortlichen für die Ausfälle der Französischen Revolution auf der Ebene der Moralität erklärt. Die Annäherung bleibt von dem Moment an nicht mehr unverständlich, da man eben die Anschauung berücksichtigt, die sich Burke vom sozialen Körper macht. Rousseau aber ist in seinen Augen nichts als ein mittelmäßiger Theoretiker : was er aus den menschlichen Leidenschaften macht (indem er den Ausbruch purer Sentimentalität in der Welt des Politischen einbringt), ist viel höher als sie zu veranschlagen.
Cuando el monstruo se hace diabólico. Magia, hechizos y conjuros en la religiosidad castellana del siglo XVII

Selon les croyances chrétiennes, le diable peut adopter l'aspect qui convient le mieux à la poursuite de ses fins. Cette faculté de métamorphose a donné lieu à l'établissement d'un polymorphisme complexe. Pourtant, l'esthétique du Baroque, fascinée par l'univers du rare et du bizarre, semble à peine intéressée par la figure de Satan.
Le baroque et le monstrueux. À propos de Góngora et Gracián
Authors: Blanco Mercedes
Published: August 2023

We might speak of a poetics of the monstruous in Góngora. Looming in the field of hyperbolic or paradoxical figures, the monster is a central principal of his writing. In Gracián's El Criticón, the monster becomes a category of moral thought, a concept so enlarged as to embrace the typical manifestations of the human being. Fragments of the late gothic morphology of the monstruous endure as membra disjecta in Spanish baroque literature – though their status has changed. In the Seventeenth century, monstrosity issued from the perspective adopted by the artist ; his vision and method of representation converged to create it.
El monstruo y la hipérbole : de la microestructura a la macroestructura semántica
Authors: López alonso Covadonga
Published: August 2023

La ponencia presenta la figura de la hipérbole como uno de los mecanismos lingüísticos más frecuentes para dar cuenta de la noción de lo anormal que cabe en el término «monstruo». Se define la hipérbole como una operación de cuantificación que provoca una transformación semántica. A partir de esta definición, se estudian su calor extensional y cuantitativo – nivel micro-estructural – y su plano intencional, esencialmente cualitativo – nivel macroestructual –. La proposición teórica se centra en el análisis de Gramática Parda de Juan García Hortelano.

Authors: Mirmoeini Seyedeh Sahar , Sari Abbas Ali , Goudarztalejerdi Ali , Pajohi Alamoti Mohammadreza , Staji Hamid
Published: August 2023

Background & Aims: Today, food-borne diseases are known as one of the most important public health concerns in many countries. Campylobacter is one of the most prevalent food-borne pathogens. Raw chicken meat has been reported as the main source of human campylobacteriosis. The present study was conducted to investigate the prevalence of Campylobacter species among broiler carcasses at industrial slaughterhouses in Hamedan province, west of Iran. Materials and Methods: Totally, 100 samples were collected using sterile swabs from chicken skin at the post-scalding stage. The samples were enriched in Brucella broth containing Campylobacter selective supplement and incubated at 42º C for 48-72 hours under microaerophilic conditions. The molecular detection and identification of Campylobacter species were performed by the polymerase chain reaction (PCR) using cadF and Hip primers for detecting Campylobacter species and Campylobacter jejuni, respectively. Results: The results of this study revealed that 81% and 31% of broiler carcasses were positive for the presence of Campylobacter species and C. jejuni, respectively. Conclusion: Due to the high contamination rate of chicken meat with this pathogen, precise hygienic control of poultry meat and an increase in consumer awareness seem necessary to decrease human campylobacteriosis.

The moving chord method for determining the curvature of the track axis
Authors:   Politechnika Gdańska, Koc Władysław
Published: August 2023

Abstract: The paper adresses the issue of determining the curvature of the axis of the railway track in order to enable the determination of the geometrical characteristics of the measured route. A new concept of determining the curvature was used by the method of changing the angles of inclination of a moving (virtual) chord based on the knowlege of the Cartesian coordinates of a given region of the route. The verification of the proposed method, carried out on unambiguosly defined model geometric track layouts, showed the complete agreement of the obtained curvature diagrams with the diagrams constituting the basis for obtaining the corresponding geometric solution. The use of the moving chord method to determine the curvature of the operated railway track showed that the obtained curvature plots clearly differ from those for model layouts; they have a less regular, oscillating character, which results from the track deformation and measurement error. However, this does not prevent the possibility of estimating the basic geometrical parameters of the measured layout on this basis.

Abstract: The load-bearing capacity of natural airport surfaces directly affects the safety of air operations. Natural airport surfaces at military airports are front seat belts, work belts and side seat belts. The load-bearing capacity of the natural airport pavements must be high enough to prevent damage to the aircraft from the runway, damage to the underground infrastructure of the airport, and to enable quick restoration of the airport's operational capacity by efficient removal of the aircraft from the natural surface by airport services. That is why it is so important to have a quick and effective method of strengthening natural surfaces. The article proposes to improve the load-bearing capacity of natural airport pavements by using geogrids (airport gratings) pressed into the existing pavement. Keywords: Carrying capacity; Natural airport pavement; Safety Conducting air operations

Measurements of traffic parameters and conditions in traffic noise research
Authors:   Politechnika Białostocka, Motylewicz Marek
Published: August 2023

Abstract: The level of traffic noise depends mainly on road traffic parameters such as: traffic volume, share of trucks in traffic and vehicles speed. Traffic conditions determined by such parameters as, for example, the average travel speed, average delays at the intersection and the number of vehicles stops are also important. Their particular importance is revealed especially in the case of bad traffic conditions and a significant reduction of traffic flow. The paper presents selected methods of measuring road traffic parameters, and in particular - traffic conditions on the example of research on their impact on the noise level in the vicinity of the street and intersections. The results of these tests are also presented, determining the impact of such parameters on traffic noise as: instantaneous speed, sectional speed, average delays at the intersection entry, the number of vehicle stops, volume to capacity of the entry ratio.

The assessment of the impact of the stabilizing admixture dosed in the amount of 0.2%, 0.4%, and 0.6% in relation to the mass of cement on the change in consistency was made based on the cone drop test according to PN-EN 12350-2:2019-07. From the prepared concrete mixes, samples were also made for testing concrete density according to PN-EN 12390-7:2019-08 and compressive strength according to PN-EN 12390- 3:2019-07. For the developed composition of the concrete mix, a standard (reference) mix was prepared, which was used to compare the test results from samples containing admixture in different amounts. Based on the tests carried out, it was found that the applied stabilizing admixture based on starch with a different percentage share concerning the mass of cement significantly reduces the consistency. The use of an admixture in the case of a concrete mix with too high consistency gives the possibility of changing its purpose without affecting the other parameters. Keywords: Concrete mix; Starch; Concrete consistency
