Authors: Ortega Chávez Elizabeth , Velasco De León Ma. Patricia , Estrada Ruiz Emilio
Published: November 2024

En la Formación Tecomazúchil del Jurásico Medio de la región de Partideño, Oaxaca, se ha registrado paleoflora de Bennetitales, además de haberse recolectado material de maderas fósiles. De este material se describen dos nuevos registros con base en estructuras anatómicas, las cuales nos permitió relacionarlas con los géneros de fósiles Agathoxylon y Protophyllocladoxylon. El taxón identificado como Agathoxylon sp. se caracteriza por la ausencia de anillos de crecimiento, punteaduras radiales, predominantemente biseriadas alternas y, ocasionalmente, parcialmente uniseriadas de forma circular, punteaduras en los campos de cruzamiento de tipo araucarioide, con cuatro a ocho punteaduras. La segunda madera tiene afinidad con el género fósil Protophyllocladoxylon sp., el ejemplar no presenta anillos de crecimiento, en su lugar presenta punteaduras radiales biseriadas alternas parcialmente uniseriadas, ocasionalmente triseriadas de forma poligonal y circular, punteaduras de tipo phyllocladoide de una a dos de forma elíptica que ocupan todo el campo de cruzamiento. Estos dos nuevos registros del Jurásico Medio amplían su distribución espacial y temporal para América del Norte, siendo que Agathoxylon ha sido ampliamente descrito y reportado para el Hemisferio Sur del continente.
El registro fósil de los ammonoideos del Carbonífero-Pérmico de México y sus aportes bioestratigráficos, paleobiogeográficos y paleoambientales: una revisión
Authors: Ruiz-Naranjo Metzeri , Torres-Martínez Miguel A.
Published: November 2024

Los ammonoideos son proxies muy recurridos en la estratigrafía por ser considerados importantes fósiles índice. Debido a su relevancia, en este trabajo se realizó una revisión exhaustiva de los reportes de ammonoideos presentes en afloramientos del Carbonífero y Pérmico de México. Se contemplaron las localidades del Anticlinorio Huizachal-Peregrina en Tamaulipas y Santiago Ixtaltepec en Oaxaca para el Carbonífero; así como las localidades de El Antimonio en Sonora, Las Delicias en Coahuila, Placer de Guadalupe en Chihuahua, San Salvador Patlanoaya en Puebla, Olinalá en Guerrero y Chicomuselo en Chiapas para el Pérmico. Los resultados arrojaron seis familias, seis géneros y seis especies para el Carbonífero, mientras que para el Pérmico se registraron 13 familias, 24 géneros y 47 especies. Con respecto a los nombres específicos, se sugiere revisar la clasificación de diferentes registros desactualizados. En cuanto a la bioestratigrafía, se reconocieron cuatro zonas de ammonoideos para el Carbonífero, abarcando desde el Viseano (Misisípico Medio) hasta el Gzheliano (Pensilvánico Superior); mientras que para el Pérmico se reconocieron de seis a ocho zonas, abarcando desde el Sakmariano hasta el Wuchiapingiano. Asimismo, se llevó a cabo una búsqueda de los registros mexicanos del Carbonífero-Pérmico para otras regiones del mundo; además se discute acerca de la paleobiogeografía del grupo, resaltando una mayor afinidad con las biotas reportadas en diversas localidades del Paleozoico tardío de los Estados Unidos. A pesar de que los ammonoideos no son clave para determinar un paleoambiente de depósito, dada su abundancia en zonas relacionadas con aguas someras o cercanas a bancos de arena o arrecifales, y su evidente ausencia en facies de ambientes profundos, se señala que durante el Carbonífero–Pérmico pudo haber existido cierta preferencia de dichos organismos por habitar ambientes someros.
Estratigrafía y paleontología del Grupo Cabullona (Campaniano-Maastrichtiano), noreste de Sonora. Síntesis para una excursión a la Cuenca Cabullona
Authors: González-León Carlos M. , Serrano-Brañas Claudia Inés , Villanueva-Amadoz Uxue , Scott Robert W. , Duarte Bigurra Rubén
Published: November 2024

La Cuenca Cabullona, ubicada en el noreste de Sonora, se formó como una depresión cortical asociada a la falla Cabullona, la cual a su vez formó al levantamiento de la Sierra Anibacachi-Cerro Cabullona. Su relleno sedimentario fue asignado al Grupo Cabullona por Taliaferro (1933), quien también nombró a las formaciones Arenisca Camas, Lutita Packard y Lomas Coloradas para la parte más joven del Grupo. Posteriormente González-León y Lawton (1995) reconocieron a las formaciones Conglomerado El Cemento y Corral de Enmedio. La sucesión sedimentaria del Grupo Cabullona alcanza un espesor mínimo de 4.5 km y consiste de lutita, arenisca y conglomerado que fueron depositadas en ambientes de abanicos aluviales, ríos, lagos y deltas, y también registra una breve incursión marina en calizas de la Formación Corral de Enmedio. La edad del Grupo Cabullona, del Campaniano al Maastrichtiano temprano indicada por algunos de sus fósiles, coincide con su edad U-Pb de entre 81.9 ± 0.7 a 69.8 ± 0.7 Ma obtenida del fechamiento isotópico de capas de rocas volcánicas intercaladas en los sedimentos. Las rocas de este grupo contienen una diversidad de restos fósiles de organismos terrestres y acuáticos que incluyen a dinosaurios, peces, tortugas, lagartijas, cocodrilos, plantas (madera, impresiones de hojas, carofitas y polen), bivalvos, gasterópodos y en menor abundancia microfósiles de origen marino. De acuerdo a los ambientes interpretados en que fueron depositadas estos sedimentos y por los fósiles que contienen, se puede inferir que, a finales del Período Cretácico, en esta región de Sonora prevalecían climas húmedos, existían grandes ríos y lagos, y una abundante vegetación que sostenía a vertebrados de tamaños grandes entre los que destacaban los dinosaurios herbívoros y carnívoros. Esta región se localizaba también en una posición cercana a las costas de un mar que se encontraba hacia el oriente, cubriendo gran parte del norte de México.
Philosophical and Scientific Implications of Astrobiology and Palaeontology in the Light of Hypothesising the Existence of Intelligent Pre-human Civilisations on Earth: Empiricist, Rationalist, and Positivist Approaches
Authors: Sánchez-Beristain Francisco , Paredes-Arriaga Alejandro , Martínez-Velarde María Fernanda , Badillo-Avilés Shendel
Published: November 2024

In this paper, the scientific and philosophical implications of the theory that suggests the existence of an intelligent civilisation on Earth prior to mankind is discussed. All available scientific evidence which would constrain such theory is brought into discussion. Therefore, we first review the Drake Equation regarding this hypothesis. We summarily appraise the Shadow Biosphere within the scope of the theory. Subsequently, we thoroughly analyse important geochemical and sedimentological constraints of the proposal, mainly in the context of some Fossillagerstätten. This leads us to discuss the philosophical implications this theory may have for the fields of Astrobiology and Palaeontology, analysing them under empiricist, rationalist, and positivist approaches. We contextually examine the concepts of technological species, intelligence, and industrialisation, taking into account the scope of the theory. Furthermore, we debate on the validity of this hypothesis, considering all constraints it presents regarding the analysed concepts. Finally, we propose to appraise the hypothesis under an epistemological/positivist point of view.

Authors: Eguiluz-de Antuñano Samuel , Hernández Ocaña María Isabel
Published: November 2024

En la Formación Auhichila hay trazas fósiles que se identifican a nivel icnogenérico como Planolites, Palaeophycus, Cochlichnus, Thalassinoides, Camborygma y ?Protovirgularia, así como rizolitos. Estas trazas posiblemente se asocian con la icnofacies Scoyenia, la cual se caracteriza por desarrollarse en sedimentos detríticos bien oxigenados de planicies de inundación y litoral lacustre. Se describe por primera vez la taxonomía de icnogéneros del Paleógeno en depósitos continentales en el noreste de México. Ante la carencia de fósiles, el conjunto icnogenérico ratifica el ambiente de depósito previamente interpretado. Tobas de extracuenca intercaladas en la sucesión datan al depósito como Oligoceno. La Formación Ahuichila tiene asociaciones de litofacies que se interpretan como sub-ambientes de abanico aluvial, fluvial, evaporítico y lacustre somero, en ellos se alojan selectivamente los icnogéneros estudiados. El conjunto de trazas se encuentra en condiciones de flujo hidrodinámico variable, con alternancia de condiciones húmedas y áridas durante su depósito. Deformación de sedimento blando se vincula con la evolución sintectónica de esta formación.

El desarrollo histórico de la paleontología en el noroeste de México, particularmente en el estado de Sonora, es poco conocido. Mediante un análisis e investigación bibliográfica se han documentado para el estado las cuatro etapas históricamente identificadas del desarrollo de la paleontología en México. Lo anterior ha permitido conocer en detalle los antecedentes históricos y el contexto de las cuatro etapas en Sonora, las cuales permitieron la institucionalización de esta ciencia en el noroeste de México. La bibliografía paleontológica de Sonora es amplia, sin embargo, para este trabajo únicamente se han considerado aquellas investigaciones que por su novedad o área de estudio han sido relevantes y/o trascendentales para el desarrollo de esta ciencia. A través de los casi 160 años de estudios paleontológicos en el estado de Sonora, se transita desde un incipiente desarrollo por parte de paleontólogos extranjeros hasta la madurez alcanzada en la actualidad, mediante la institucionalización de esta disciplina.

Authors: López-Conde Oliver A. , Chavarría-Arellano María L. , Porras-Múzquiz Hector , Alvarado-Ortega Jesús
Published: November 2024

New remains of a sea turtle from the San Carlos quarry (Upper Cretaceous, Campanian), Austin Formation in the north of Coahuila state, Mexico, are reported. San Carlos quarry is composed of limestones and its Campanian age is based on the presence of the ammonites Scaphites hippocrepis and Delawarella delawarensis. In addition to the presence of turtles, this quarry also contained ammonites, bivalves, crabs, sea urchins, bony fish remains, and shark teeth. The study material is housed at Museo Paleontológico de Múzquiz. The preserved fossil elements correspond to postcranial elements, which present morphological characteristics that allowed them to be identified as belonging to a small-sized turtle related to Protostegidae. These new sea turtle remains expand the knowledge and distribution of Protostegidae along the Western Interior Seaway, where large and medium-sized sea turtles were distributed.

Published: November 2024

La recolecta de los fósiles de plantas dependerá mucho del tipo de yacimiento o del tipo de fosilización en el que se preservaron. En México, el registro fósil de plantas tiene como principales tipos de fosilización a la impresión, la permineralización, el encapsulamiento en ámbar y la compresión carbonosa. En este trabajo se resalta la manera “ideal” de la recolecta de material paleobotánico, así como la manera apropiada de transporte para su siguiente proceso curatorial, registro y finalmente, llenado de cedulas de ejemplares y localidades ante el Consejo Nacional de Paleontología, organismo encargado de la protección del registro paleontológico en México. Concluyendo que cualquier trabajo de recolecta paleobotánica siempre debe de contar con un objetivo.claro, metodología a emplear y un lugar de resguardo apropiado.
Pyrenicola (Crustacea: Decapoda: Brachyura), new genus for Litoricola macrodactyla (Van Straelen, 1924) and Litoricola macrodactyla pyrenaica (Artal and Vía, 1989), and remarks on Coeloma (Milne-Edwards, 1865)
Authors: Artal Pedro , Ossó Àlex
Published: November 2024

A new genus, Pyrenicola, is proposed to accommodate Xanthilites macrodactylus Van Straelen, 1924 from the Thanetian of Haute Garonne (France), and X. macrodactylus pyrenaicus Artal and Vía, 1989 from the Ypresian of Aragon (Spain), as well as clarify their relationships with the morphologically close Litoricola Woodward, 1873, where both are currently placed, and with Coeloma A. Milne-Edwards, 1865. As a result, Litoricola is herein revalidated as an available genus, different from Coeloma, of which it has frequently been considered either a subgenus or a synonym. Also, the subspecies Xanthilites macrodactylus pyrenaicus is elevated to full species rank as Pyrenicola pyrenaica n. comb. The familial placement of Pyrenicola n. gen., Litoricola and particularly of Coeloma, currently placed within Polybiinae Paulson, 1875 (Portunoidea Rafinesque, 1815) is revised. Consequently, a new placement of the three genera within Geryonidae Colosi, 1923, the most basal portunoid crabs, is herein proposed.

THE CONCEPT OF CULTURAL NATIONALISM AND ITS IMPLEMENTATION IN IRELAND IN THE 19th – EARLY 20th CENTURIES
Authors:   Voronezh State University (Russia), Miroshnikov A. V. , Shishkina I. B. ,   Voronezh State University (Russia)
Published: November 2024

In the article, the authors attempt to analyze one of the most important components of the Irish national movement of the 19th – early 20th centuries, cultural nationalism. Irish nationalism throughout its history has tended to variously highlight issues of political liberation or self-government, agrarian and religious issues. Priorities largely depended both on the prevailing ideas of the leaders of the movement in a particular period, and on the corresponding political and social atmosphere. An important role was also played by the commitment of the leaders of nationalist organizations to the methodology for implementing their programs, be it “physical” or “moral strength”. However, the total dictatorship of Britain in imposing English culture, language, traditions, education with severe pressure on Irish culture, demanded from nationalists the formation of the identity of the Irish nation, the renovation of the rich national heritage. With the change in the social state of society at the turn of the 19th and 20th centuries, cultural nationalism gained a huge audience, while updating new directions in culture. The revolution of 1916-1923, while solving the problem of winning independence, also included the problem of national self-identification.

Published: November 2024

A cárie dentária é uma doença multifatorial que acomete diferentes populações no decorrer da vida. Está diretamente associada aos processos de desmineralização e remineralização do esmalte dentário. Quando o processo infeccioso atinge a dentina, classifica-se em dois tipos: infectada, que apresenta alto índice de desmineralização, consistência amolecida, aspecto amarelado e irregular, incapaz de remineralizar-se; e afetada, que se encontra abaixo da infectada, possuindo quantidade reduzida de microrganismos, além de ser mais dura, coloração escurecida e capacidade de remineralização. A metodologia utilizada neste trabalho consistiu em uma revisão de literatura em livros e artigos associados à remoção seletiva de tecido cariado em dentes permanentes. Foram selecionados artigos disponíveis nas plataformas Scielo, PubMed, BVS, Google Acadêmico e livros da biblioteca virtual da Universidade de Sorocaba, com os descritores: Dental Caries, Caries e dentition permanent, nos idiomas inglês e português. Dessa forma, com base nos estudos e seus resultados expostos, a remoção seletiva de tecido cariado em dentes permanentes apresenta índices elevados de efetividade, principalmente quando é executada em lesões muito profundas, uma vez que, quando comparada à técnica de remoção total, o risco de exposição pulpar torna-se menor.

Published: November 2024

Myocardial infarction (MI) is a serious cardiovascular disease and the primary cause of mortality, with a complex etiopathology. Identifying the genetic basis of myocardial infarction (MI) is essential for developing personalized medical treatments. This study examined the possible association between polymorphisms in the methylenetetrahydrofolate reductase (MTHFR) gene and MI. In the study, 120 patients with MI and 120 age-and-sex-matched controls were genotyped for C677T and A1298C MTHFR polymorphisms by the allele-specific or amplification refractory mutation system-polymerase chain reaction (ARMS-PCR). In the case of the C677T polymorphism, the T/T and C/T genotypes were associated with a significantly increased risk of MI under the dominant genetic model (odds ratio (OR)=2.060; P=0.006). Although there was no significant association between the A1298C variant and MI, this polymorphism was linked to a higher level of creatinine in MI patients (P<0.002). A similar association was observed for the C677T polymorphism (P=0.003). An A-T haplotype represented an increased risk for MI (OR=1.630; P=0.014), whereas the A-C haplotype had a protective role (R=0.517; P=0.002). These findings indicate that C677T MTHFR polymorphism is strongly associated with and increased risk of MI, making it a potential genetic risk factor and a possible predictor of MI.
Effects of Obesity and Hyperglycemia on Postprandial Insulin-Mediated and Non–Insulin-Mediated Glucose Disposal
Authors: Mittendorfer Bettina , Patterson Bruce W. , Smith Gordon I. , Yoshino Mihoko , Klein Samuel
Published: November 2024

OBJECTIVE

To evaluate total, insulin-mediated, and non–insulin-mediated glucose disposal (TGD, IMGD, and NIMGD) after ingesting glucose in people with obesity and different glycemic status.

RESEARCH DESIGN AND METHODS

We developed and validated a new glucose tracer model in conjunction with an oral glucose tolerance test to determine IMGD, NIMGD, and TGD (sum of IMGD and NIMGD) after glucose ingestion in four groups of people: 1) lean with normal glucose tolerance (NGT), 2) obese with insulin resistance and NGT due to hyperinsulinemia (Ob-NGT group), 3) obese with insulin resistance and impaired glucose tolerance (IGT) due to inadequate hyperinsulinemia (Ob-IGT group), and 4) obese with insulin resistance and type 2 diabetes due to marked insulin insufficiency (Ob-T2D group). In addition, we evaluated the effect of intensive lifestyle therapy (ILT) that caused ∼15% weight loss on IMGD and NIMGD in people with obesity and type 2 diabetes (T2D).

RESULTS

IMGD progressively decreased and NIMGD progressively increased from lean to Ob-NGT to Ob-IGT to Ob-T2D. IMGD accounted for about 70%, 65%, 50%, and 20% of TGD, and NIMGD accounted for ∼40%, 35%, 50%, and 80% of TGD in lean, Ob-NGT, Ob-IGT and Ob-T2D, respectively. Although NIMGD was approximately twofold and approximately threefold higher in Ob-IGT and Ob-T2D compared with Ob-NGT, NIMGD only partially compensated for markedly impaired IMGD in the Ob-IGT and Ob-T2D. ILT in people with obesity and T2D increased IMGD and decreased NIMGD.

CONCLUSIONS

NIMGD is a major mechanism of postprandial TGD in people with insulin resistance and inadequate insulin secretion.

Authors: Casamenti Enrico , Bruno Alessandro , Bernasconi Pietro , Lovera Andrea
Published: November 2024

Due to its exceptional dimensional stability in harsh thermal conditions and excellent mechanical and optical properties, Corning ultralow expansion (ULE®) glass is the material of choice in many high-demanding fields such as aerospace, astronomy, and advanced optics. This material has recently attracted renewed attention with the advent of femtosecond laser technology, with a particular focus on the interaction of ultrafast pulses and the material itself. Phenomena like the formation of self-assembled nanogratings and their thermal stability as well as the darkening of laser-affected zones have then been characterized. This paper presents how to exploit femtosecond selective laser etching (SLE) techniques to manufacture truly three-dimensional components. To demonstrate the micrometer-scale accuracy and repeatability of this process from the mm- to the cm-size range, various devices are designed and fabricated: fiber hole arrays with different hole densities, sizes, orientations, and shapes; and fiber V-groove arrays. Additionally, a mechanical flexural fiber mount is presented as an example of how multiple functionalities can be monolithically integrated into a single piece of glass through SLE technology. An example of a passive alignment substrate for optical components is also shown. SLE technique represents a new advancement in the field of microscale manufacturing, enabling the scalable production of custom-designed ULE® glass structures with unprecedented precision and complexity, paving the way for the miniaturized integration of highly stable components.
Development of a Web-Based Expert System for Diagnosing Cocoa Diseases Using Forward Chaining and Certainty Factor Methods
Authors: Saad Muhammad Ibnu , Pratiwi Heny
Published: November 2024

Cocoa plant diseases have a detrimental impact on farmers and cultivators. This is due to the limited number and working hours of cocoa plant experts. Another thing is that there are quite a lot of farmers who want to consult, which results in less than optimal handling of cocoa diseases. Therefore, researchers developed an expert system to help diagnose and provide solutions based on disease symptoms experienced by cocoa plants, so that farmers do not need to consult directly with experts. This research uses the forward chaining method in preparing rules and adds the certainty factor (CF) method to calculate the certainty value so that the resulting decisions are more accurate. From the results of manual calculations using a sample of one disease with code P1, the trial showed an accuracy value of 93.0736%. Apart from that, the system was proven to work well and was able to make diagnoses based on symptoms on cocoa plants.

Authors: Dang Tuan
Published: November 2024

Scissor lifts are special devices for transporting or lifting with a wide range of applications. By extending or retracting the hydraulic cylinder arranged in the scissor frame, the system can raise or lower the platform to the designated height. This study was conducted to analyze the relationship between the configuration of the cylinder and the movement of the platform in single-stage scissor lifts. By applying a numerical method and assigning parameters for the cylinder arrangement, the displacement of the platform and the forces in the cylinder can be easily calculated. The results obtained from the calculation process show the practicality of the proposed method in determining the optimal configuration for designing single-stage scissor lift systems.

Canine corona virus (CCoV) infection is a new emerging disease affecting dogs. It results in low mortality but considerable morbidity in dogs with intermediate to moderate enteritis. In India, serological research on dogs has revealed the existence of antibodies, demonstrating the prevalence of the condition among canines. The aim of the present study was to investigate the prevalence of CCoV infection in dogs suffering from gastroenteritis, and genetic analysis of circulating virus strains. The current study was designed to test fecal samples of dogs with gastroenteritis suspected for the presence of CCoV. Using primers based on the M-gene, PCR was used to amplify the RNA (c-DNA) templates retrieved from the fecal samples. RT-PCR based detection of CCoV showed positivity of 30% (15/50). The phylogentic analysis revealed that two samples had nt/aa identity levels of 100%/100% to the CCoV isolate from China and 99.19/100% of nt/aa identity with that from Korea. One of the samples showed divergence and revealed 95.63%/94.37% nt/aa identity with the China isolate and 95.15%/97.06% nt/aa identity with Indian isolates. The recombination analysis indicated a mutation rate in one of the samples. In brief, the present study illustrates the circulation of canine corona virus in dogs suffering from gastroenteritis. The present findings emphasize the need for vaccination of dogs for prevention, as a high prevalence of viral gastroenteritis was found in these dogs.
