Paleomagnetism and 40Ar/39Ar ages of ignimbrites, Mogollon-Datil volcanic field, southwestern New Mexico
Authors: McIntosh William C. , Kedzie Laura L. , Sutter John F. 
Published: March 2023

This report presents 40Ar/39Ar sanidine ages and paleomagnetite data for 36 ignimbrites and associated lavas in the Eocene-Oligocene Mogollon-Datil volcanic field of southwestern NM.40Ar/39Ar age spectra from the ignimbrites yield plateau ages that range from 36.2 to 24.3 Ma and show within-sample and within-unit 1s precision of +/- 0.5% or better. These ages agree closely with independently established stratigraphic order and indicate that Mogollon-Datil ignimbrite activity was highly episodic, being confined to four brief (< 2.6 Ma) eruptive intervals separated by 1.5-3 Ma long hiatuses.Ignimbrite outflow sheets show stable paleomagnetic remanence directions that are uniform over most of their areal extents, including facies ranging from thick, densely welded proximal ignimbrites to unwelded distal fringes as thin as 1.5 m.Used in concert with lithologic and stratigraphic position data, 40Ar/39Ar ages and paleomagnetic directions allow accurate long-range ignimbrite correlations that provide reliable ties between previously established subregional stratigraphic sequences. These correlations have helped to establish an integrated time-stratigraphic framework for the Mogollon-Datil volcanic field.
Sedimentology of the Upper Cretaceous rocks of Todilto Park, New Mexico
Authors: Willard Max E. 
Published: March 2023

This study involves the fundamental sedimentology of the complex transgressive-regressive Upper Cretaceous sediments exposed at Todilto Park, west of Tohetchi, New Mexico. The three measured and sampled sections represent approximately 3,000 ft of strata ranging from the Jurassic Morrison Formation through the Cretaceous sandstones, siltstones, and shales of the Dakota(?), Mancos, and Mesaverde. These sections have been differentiated and correlated on the basis of physical and mineralogical characteristics.Five principal petrographic zones have been recognized and each zone has been further subdivided on the basis of its clay mineralogy. Each principal zone is named for the distinctive accessory heavy mineral or minerals it contains. The recognized zones in their order of occurrence, starting at the base of the sections, are (1) staurolite, (2) tourmaline-garnet-zircon, (3) biotite-chlorite, (4) sphene-zoisite, and (5) epidote. At Todilto Park, the mineral zones and the formations do not coincide. It appears that any attempt regionally to characterize a formation on the basis of its mineralogy will fail.Interpretations of the statistical parameters obtained from the size analyses of the Todilto Park samples result in conclusions that are consistent with currently accepted ideas concerning the history of Cretaceous sedimentation in the San Juan Basin. There are no large-scale abrupt changes in the mechanical composition of the sediments, and hence it appears that during their deposition there were no rapid changes in the tectonic framework of this area. As sedimentation proceeded from deposition of the Dakota through the Point Lookout, there was a gradual decrease in the energy level, a decrease in the rate of deposition, and an increase in the amount of reworking. The characteristics of the sediments above the Point Lookout are typical of backshore and transitional sediments. As the basin filled, these deposits encroached on the earlier beach and neritic deposits. Comparisons with recent deposits support these conclusions. Detailed interpretations of the mechanical analyses suggest that many of the Cretaceous formations include both marine and nonmarine sedimentary units. This is especially true for the Dakota(?) and Gallup Sandstones. It appears that formations deposited during a stillstand of the sea are made up of sedimentary units that are mechanically similar and characteristically very well sorted. The sedimentary units that make up a formation deposited during an interval of fluctuating sea level differ greatly and have a wide range of sorting.Clay and heavy mineral data suggest that the effects of intrastratal solution have not appreciably altered the character of the original mineral assemblages. Most of the diagenetic alterations were produced by acid solutions. The observed products of alkaline reactions are associated with montmorillonite that probably was derived from the alterations of volcanic ash.
Stratigraphy and paleontology of the Mississippian System in southwestern New Mexico, and adjacent southeastern Arizona
Authors: Armstrong Augustus K. 
Published: March 2023

The Mississippian system was studied in western Cochise County, Arizona, and in Luna, Hidalgo, and Grant Counties, New Mexico. The primary concern was with the Osage through Meramec Escabrosa Limestone, its stratigraphy, paleoecology, and biologic contents. The Escabrosa Limestone is regarded as a group and has been divided into two formations. These are, in ascending order, the Keating Formation, and the Hachita Formation. The Escabrosa Group has a minimum thickness of 650 ft in the Peloncillo Mountains and a maximum thickness of 1,000 ft in the Big Hatchet Mountains of New Mexico. In the area of this report, it is primarily an encrinite with minor amounts of microcrystalline limestone. These sediments represent almost continuos deposition through all of Osage and Meramec time. The strata were deposited over a slowly sinking shelf area in shallow normal-marine waters.The corals, brachiopods, blastoids, and endothyrids collected from the Escabrosa Group are described and illustrated. The following new species were found: Chonetes klondikia, Unispirifer balki, Amplexizaphrentis sonoraensis, A. northropi, Vesiculophyllum sutherlandi, Lithostrotionella lochmanae, and Michelinia leptosphragma.The late Meramec to middle Chester Paradise Formation was studied and part of its brachiopod fauna described. The Paradise Formation is an alternating series of medium-bedded limestones and shales, with a maximum thickness of 220 ft in the Big Hatchet Mountains. It thins rapidly to the north and to the west, and is only about 80 ft thick in the eastern Chiricahua Mountains of Arizona. The Helms Formation of Chester age was studied in the Franklin Mountains and its coral fauna, including the new coral species Koninickphyllum elpasoensis, described.

El presente artículo se enmarca en el trabajo de investigación en curso “Órdenes geométricos y trasdisciplina en la generación de la forma arquitectónica contemporánea” que integra conocimientos y métodos de diversas disciplinas, para precisar estrategias que aporten a la enseñanza de la morfología arquitectónica. La metodología se basa en la identificación de principios de orden, leyes y patrones con potencial capacidad de sistematización, transferencia y aplicación para la generación de la forma.
Doberti describe la relación entre forma e interdisciplina, y plantea que: “La Morfología Primera se ocupa de la lógica de la Conformación, se centra en ella y sólo atiende a los escalones necesarios para alcanzar la Forma” (2008, p. 108) y también expone que: “La forma es generadora de las disciplinas y posibilitadora de la interdisciplina, así como habilitadora de la penetración de los límites” (2008, p. 109).
Convergen en este caso, para ser posteriormente transferidas, indagaciones en la cinemática que se enfoca en el estudio particular de las trayectorias de movimiento de los cuerpos en el espacio, sin atender a las fuerzas que lo producen y por otro lado la cimática, que estudia las representaciones visuales de las ondas sonoras y los fenómenos periódicos de vibración sobre la materia.

Background: Blood transfusion is an essential lifesaving treatment. The unsafe blood transfusion practices are one of the reasons of spreading transfusion-transmissible infections among individuals. It is necessary to screen the all donated blood units for HBV, HCV, HIV, VDRL, and MP.
Aims: This aim of this study was to evaluate the burden of transfusion-transmissible infectious diseases caused by blood transfusions among donors.
Materials & Methodology: It was a prospective observational study which included the 9114 blood donors who attended the Akhtar Saeed Trust Hospital Lahore from January 2020 to September 2022. The informed consent was taken from all blood donors. 3-5 ml of venous sample was drawn by using aseptic technique from blood donors on enrollment. Screening of blood donors was done by Chemiluminescence immunoassay (Maglumi-800) for HBV, HCV, HIV and VDRL. The MP was confirmed by peripheral blood picture on slide. According to the automation kit manufacturer’s guidelines, cut-off value for reporting positive results of HBV, HCV, HIV and VDRL was calculated. Data was analyzed by using SPSS version 25.0.
Results: The mean age was 27.79 + 12.1 years. The numbers of volunteer and replacement donors were 961 (10.54%) and 8153 (89.45%) respectively. The total numbers of positive donors for transfusion transmissible infectious diseases were 591/9114 (6.49%). The seropositivity was found to be 170/9114 (1.86%) for HBV, 324/9114 (3.55%) for HCV, 33/9114 (0.36%) for HIV, 64/9114 (0.70%) for VDRL, and 0/9114 (0.0%) for MP respectively.
Conclusion: There is currently a low risk of transfusion transmissible infectious diseases but the availability of safe blood is contingent on screening tests and appropriate donor selection.

Los realistas desleales en Puno, Perú (1814-1816).
Authors: Amat y León Eric 
Published: March 2023

In the wake of the royalist victory at Umachiri on March 11, 1815, the insurrection spread throughout the Intendancy of Puno. ‘Pacification’ required three military campaigns over the following year. Thousands perished, and the provinces were devastated. The Spanish authorities told a tale of white extermination to placate the wavering loyalty of their subjects. Untold is the identity of the insurgent leadership, dominated by former royalist officials. A survey of the records traces the origins of disloyalty to the crisis of Spanish legitimacy. The Constitution of Cadiz (1812) ushered the promise of a new era of governance. But those in power resisted change. Lacking the legal and political authority, the royalists resorted to the use of force to quell the pace of the reforms, and arrested constitutionally elected officials and their supporters. The political situation devolved, popular resentment mounted, and an increasingly defiant population turned to armed conflict as the provinces of Puno descended into chaos.
A raíz de la victoria realista en la batalla de Umachiri, que se llevó a cabo el 11 de marzo de 1815, la insurrección se extendió por el territorio que comprendía la intendencia de Puno. La “pacificación” de esta jurisdicción requirió de tres campañas militares durante el año siguiente para ser derrotada. Dichas campañas fueron costosas pues miles de personas perecieron y las subdelegaciones fueron devastada Es así como las autoridades españolas contaron una historia de exterminio para aplacar la lealtad vacilante de sus súbditos. Sin embargo, no se ha contado acerca de la identidad del liderazgo insurgente que tuvo como características principales estar dominada por exfuncionarios monárquicos. La pesquisa de documentos permite rastrear los orígenes de estas deslealtades con el inicio de la crisis monárquica. La Constitución Política de la Monarquía Española (1812) marcó el comienzo de la promesa de una nueva jerarquía. Es a raíz de estos acontecimientos que hubo una marcada resistencia a los cambios políticos. Las autoridades realistas emplearon el uso de la fuerza para sofocar la utilización legítima de las nuevas políticas de gobierno. Estuvieron en contra de las reformas, arrestaron a funcionarios constitucionalmente electos y a sus partidarios, por lo que la situación política involucionó, aumentó el resentimiento político y una población cada vez más desafiante recurrió al conflicto armado en el espacio puneño.

Published: March 2023

Background: Mueller-Weiss disease, a rare and complex foot condition, is defined as spontaneous and progressive navicular fragmentation leading to midfoot pain and deformity. However, its exact etiopathogenesis remains unclear. We report a case series of tarsal navicular osteonecrosis to describe the clinical and imaging characteristics and etiologic profile of the disease.
Methods: This retrospective study included five women diagnosed as having tarsal navicular osteonecrosis. The following data were extracted from medical records: age, comorbidities, alcohol and tobacco consumption, history of trauma, clinical presentation, imaging modalities performed, treatment protocol, and outcomes.
Results: Five women with a mean age of 51.4 years (range, 39–68 years) were enrolled in the study. Mechanical pain and deformity over the dorsum of the midfoot was the main clinical presentation. Rheumatoid arthritis, granulomatosis with polyangiitis, and spondyloarthritis were reported by three patients. Radiographs revealed bilateral distribution in one patient. Three patients underwent computed tomography. It showed a fragmentation of the navicular bone in two cases.Magnetic resonance imaging was performed in one patient showing flattening of the lateral aspect of the navicular bone with signal abnormalities. Talonaviculocuneiform arthrodesis was performed in all of the patients.
Conclusions: Mueller-Weiss disease–like changes may occur in patients with an underlying inflammatory disease such as rheumatoid arthritis and spondyloarthritis.

Authors: Rady Hebatulla M. A. , Shama Mostafa A. 
Published: March 2023

Aims: Evaluate eight landraces of okra and five landraces of molokhia, collected from different region of Egypt, under different levels of irrigation water salinity.
Study Design: The experimental design used was a split-plot in a randomized complete blocks design with three replicates, where the four irrigation water salinity concentrations were arranged in the main plots, whereas, landraces of okra or molokhia were arranged in the sub plots.
Place and Duration of Study: This investigation was carried out during the two successive summer seasons of 2021 and 2022 at Soil Salinity Laboratory Research, Alexandria Governorate, Agricultural Research Center.
Methodology: Four levels of saline irrigation water were applied having EC of 625 (tap water as a control), 2000, 4000 and 6000 ppm which was applied as necessary according to soil field capacity (27.85%).
Results: Generally, all the studied traits, of okra and molokhia, decreased as the salinity level increased except for the spines of edible pods which was in contrast, in both seasons. There were significant differences among the studied eight landraces of okra and the studied five landraces of molokhia for all the studied traits in both seasons. Edible pods yield/plant of Behera landrace was not significantly affect by irrigation at salinity levels up to 2000 ppm of salinity level in 2022 season. Moreover, Alexandria and Gharbya landraces were the least affected by increasing salinity levels comparing with the rest of landraces in both seasons. With respect to molokhia, Fresh leafy yield/plot of Alexandria landrace was not significantly affected by irrigation at salinity levels up to 2000 ppm of salinity level in the first seasons.
Conclusion: It can be recommended to cultivate Behera, Alexandria and Gharbya landraces of okra and Alexandria and Kafr Elsheikh landraces of molokhia when irrigation with relatively high levels of salinity, as these landraces were relatively less affected by increasing salinity concentration. These landraces can also be introduced into breeding programs to improve them or develop new varieties that are more salt-tolerant.

Background: The success of in vitro-fertilization (IVF) cycles is determined in large part by the quality of embryo cleavage, which in turn, is dependent on the quality of the embryo culture media (CM). Many factors can influence the quality of embryo CM, one of which is the levels of Cell Free Deoxyribonucleic acid (DNA). Understanding the association between Cell-free DNA levels in embryo CM and the quality of embryo cleavage could help improve the quality of IVF techniques.
Methods: This prospective study was conducted with 96 spent CM from patients undergoing IVF cycle, in order to determine relationships of Cell-free DNA levels in embryo CM with embryo cleavage quality on day 3. After intracytoplasmic sperm injection (ICSI), 48 embryos were evaluated on day 3 of their development, according to their cell number. Day 2 and day 3 CM corresponding to each one of the embryos was analyzed, by quantitative PCR, for estimation of Cell-free DNA levels.
Results: The results revealed a significant increase in Cell-free DNA levels on day 2 CM corresponding to 4 to 6 cell embryos compared to those corresponding to 7 to 8 cell embryos (p=0.04). As for day 3 CM, the results showed no significant difference between the Cell-Free DNA levels in CM of 7-8 and those of 4-6 cell embryos (p=0.4). Also, cell free DNA levels in embryo CM, were significantly higher on day 2 compared to day 3 for both 7-8 and 4-6 cell embryos (p=0.03; p=0.04).
Conclusion: We conclude that cell-free DNA levels in CM might be associated with delayed embryo cleavage.

ImportanceEvidence suggests that women with a family history of breast cancer (FHBC) in first-degree relatives have a higher level of breast density; however, studies of premenopausal women remain limited.ObjectiveTo investigate the association between FHBC and mammographic breast density and breast density changes among premenopausal women.Design, Setting, and ParticipantsThis retrospective cohort study used population-based data obtained from the National Health Insurance Service–National Health Information Database of Korea. We included premenopausal women aged 40 to 55 years who underwent mammography for breast cancer screening once between January 1, 2015, and December 31, 2016 (n = 1 174 214), and women who underwent mammography twice (first in 2015-2016 and again between January 1, 2017 and December 31, 2018) (n = 838 855).ExposuresFamily history of breast cancer was assessed using a self-reported questionnaire, which included information on FHBC in the mother and/or sister.Main Outcomes and MeasuresBreast density, based on the Breast Imaging Reporting and Data System, was categorized as dense (heterogeneously or extremely dense) and nondense (almost entirely fat or scattered fibroglandular areas). Multivariate logistic regression was used to assess the association among FHBC, breast density, and changes in breast density from the first to second screening. Data analysis was performed from June 1 to September 31, 2022.ResultsOf the 1 174 214 premenopausal women, 34 003 (2.4%; mean [SD] age, 46.3 [3.2] years) reported having FHBC among their first-degree relatives, and 1 140 211 (97.1%; mean [SD] age, 46.3 [3.2] years) reported no FHBC. Odds of having dense breasts was 22% higher (adjusted odds ratio [aOR], 1.22; 95% CI, 1.19-1.26) in women with FHBC than in women without FHBC, and the association varied by affected relatives: mother alone (aOR, 1.15; 95% CI, 1.10-1.21), sister alone (aOR, 1.26; 95% CI, 1.22-1.31), and both mother and sister (aOR, 1.64; 95% CI, 1.20-2.25). Among women with fatty breasts at baseline, the odds of developing dense breasts was higher in women with FHBC than in those without FHBC (aOR, 1.19; 95% CI, 1.11-1.26), whereas among women with dense breasts, higher odds of having persistently dense breasts were observed in women with FHBC (aOR, 1.11; 95% CI, 1.05-1.16) than in those without FHBC.Conclusions and RelevanceIn this cohort study of premenopausal Korean women, FHBC was positively associated with an increased incidence of having increased or persistently dense breasts over time. These findings suggest the need for a tailored breast cancer risk assessment for women with FHBC.
