¿Independencia en tiempos del Tren Maya?
Authors: Hernández Castillo Rosalva Aída , Rueda Elisa Cruz 
Published: November 2021

En este ensayo, abordamos, desde la etnohistoria y la antropología política, el significado que tuvo el evento histórico conocido como la independencia de México para los pueblos originarios. En diálogo con la literatura que aborda el colonialismo como una estructura que sigue marcando la vida de los pueblos indígenas –y no como un evento histórico que se vio interrumpido por las guerras de independencia–, analizamos el continuum de violencias coloniales que ha caracterizado la historia contemporánea de estos pueblos. Documentamos las manifestaciones de estas violencias durante el gobierno actual de Andrés Manuel López Obrador (2018–23), tomando como ejemplo el principal proyecto de “desarrollo” de la actual administración, conocido como el Tren Maya. A partir de la información recabada en una investigación colaborativa, desde el activismo legal de una de las autoras, analizamos los impactos y resistencias que se han desarrollado contra este proyecto, el cual presentamos como una forma de despojo territorial.
Highly sensitive in vitro bioassay for luteinizing hormone and chorionic gonadotropin allowing their measurement in plasma
Authors: Klett Danièle , Combarnous Yves 
Published: November 2021

In previous studies, we had shown the synergistic effect of 10−5 M forskolin (FSK) on the detection threshold of the cyclic AMP response to luteinizing hormones (LH) and chorionic gonadotropins (CG) from various species in the mouse Leydig tumor cell (mLTC) cell line. Independently, we started to study the effect of 10−12–10−6 M oxytocin (OXT) also on the cyclic AMP response to LH and CG preparations on these same cells and found an amplifying effect on the luminescence response caused by gonadotropins. The aim was then to explore the effects of 10−12–10−6 M OXT on the gonadotropin-induced cAMP response, in the presence or absence of 10 µM FSK to optimize the assay down to a sensitivity compatible with the detection of the circulating concentrations of these hormones in various species. Finally, the optimization relies on three independent phenomena: (1) the inhibition of nucleotide phosphodiesterase by IBMX (3-isobutyl-1-methylxanthine) to avoid cAMP degradation; (2) the strong synergy of 10 µM forskolin with low concentrations of LH or CG during the 1-h luminescence measurement; (3) the stimulatory effect of 10−8M OXT on the amplitude of transfected cAMP-sensitive luciferase response. By doing this, the detectable concentrations are at the 1–10 pg/well (pM range) for the LHs and CGs from various species. The bioactivities of circulating LHs and CGs in blood or urine are therefore expected to be measurable in 10 µL-plasma samples from mammalian species and maybe others. Indeed, a preliminary study with equine and donkey plasma samples shows that the measured bioactivity was fully inhibited by a specific MAB against the receptor-binding region of equine LH (eLH) and equine CG (eCG), thus eliminating a possible response due to interfering substances other than eLH or eCG. From these data, it is expected that the bioactivity profiles of these hormones will be measurable in the blood of human, equine, and ovine species and very likely in rodents, ruminants, and hopefully in most other mammalian species.

Lay summary
Luteinizing hormone (LH) plays a central role in controlling ovary and testicle functions in many animals, including humans. The highly sensitive method, known as an assay, described in this paper, measures the biological activity of LH in the blood of mammals. The assay is performed in culture of cells derived from mouse testicles in the presence of factors that diminish the detection threshold for LH. The knowledge of the bioactive LH concentration dynamics in the blood is very informative about the reproductive status of male and female mammals. This new in vitro bioassay provides a powerful tool to get this information.

Published: November 2021

The purpose of this work is to determine the hydrochemical parameters of the water of the river Seret and the features of the accumulation of heavy metals by bivalve molluscs Unio pictorum L. to predict the chemical contamination of the reservoir in the near future. Water samples for the study were taken in spring (April) and summer (July) from the Seret River at two points: above and below Ternopil. It is established that the chemical composition of the water of the river Seret is formed under the influence of a number of factors, but seasonal and anthropogenic factors play a dominant role. In the spring season, a number of hydrochemical indicators (pH, water hardness, concentration of ΝΟ 2-, ΝН4+, Сl- ions and metals) have lower values than in the summer. In addition, there is an increase in the amount of organic matter, ammonium cations, nitrite ions, chloride ions, phosphate ions and a decrease in oxygen concentration below Ternopil, especially in the summer season. This is evidence that the Seret River is under significant anthropogenic impact. An increase in the concentration of metals (Mn, Cu and Pb) in summer below Ternopil was revealed, which may be due to the discharge of insufficiently treated wastewater. The series of metal concentrations in the water of the Seret River looks as follows Mn → Zn → Pb → Cd → Cu, and the series of accumulation of metals in the tissues of molluscs Unio pictorum L. has the form Zn → Mn → Cu → Pb → Cd. On the basis of bioaccumulation coefficients of heavy metals by molluscs, a prediction of the situation on their content in water for the short term based on the theory of Markov chains was made. This theory allows us to make forecasts of a factor, taking into account the possibility of accidental influences on the environment, and to investigate the highest probability of finding a factor in a certain numerical parameter. The possibility of using economic and mathematical modelling tools and statistical methods based on correlation-regression analysis using modern Matlab information systems to identify correlations between chemical indicators of water quality and biological molluscs for modelling the environmental situation of the river Seret and assessing the contribution of the studied indicators in pollution of small rivers is shown.

Abstract
In this study, a UPLC-MS/MS method was developed to measure the concentrations of the flavonoids oroxin A, oroxin B, oroxylin A, oroxyloside, chrysin, chrysin 7-O-beta-gentiobioside, and guaijaverin in the blank mouse blood, and the method was then used in the measurement of the pharmacokinetics of the compounds in mice. Oroxin A, oroxin B, oroxylin A, oroxyloside, chrysin, chrysin 7-O-beta-gentiobioside, and guaijaverin were administered intravenously at a dose of 5 mg kg−1, and the mouse blood (20 μL) was withdrawn from the caudal vein 0.08333, 0.25, 0.5, 1, 2, 4, 6, 8, and 10 h after administration. The mobile phase used for chromatographic separation by gradient elution was composed of acetonitrile and water (0.1% formic acid). The analytes were detected by operating in electrospray ionization (ESI) positive-ion mode using multiple reactions monitoring (MRM). The intra-day and inter-day accuracy ranged from 86.2 to 109.3%, the intra-day precision was less than 14%, and the inter-day precision was less than 15%. The matrix effect ranged from 85.3 to 111.3%, and the recovery of the analytes after protein precipitation were all above 78.2%. This method had the advantages of high sensitivity, accuracy, and recovery, and it had excellent selectivity, which enabled it to be applied to measuring the pharmacokinetics of the analytes in mice.

Published: November 2021

Background: The food industry in Malaysia has experienced significant development, especially in the halal food sector. The halal food industry is a market segment involved with food items and beverages that are strictly prepared according to rules underlined by the Islamic dietary law. In addition, the concept of halal covers not only Syariah law, but also hygiene, sanitation and food safety requirements. Malaysia has become a major global halal hub in delivering halal food to local and international levels. The significant development of halal food industry in Malaysia creates significant job opportunities for new graduating students. Therefore, this study aims to evaluate factors that influence student intention to choose a career for the halal food industry in Malaysia.

Research Methodology: This study using a quantitative research method with questionnaire development in assessing the factors that influence intention of students to involve in halal food industry as their future career. The underpinning theory is Theory of Planned Behavior (TPB). The independent variables are Attitude (A), Subjective Norm (SN) and Perceived Behavioral Control (PBC). This study developed four questions for each variable. Unit of analysis for respondents is university students in Malaysia. The sample size is 40 students that have an interest in working for halal food industry in Malaysia. The correlation analysis was analyzed using Pearson Correlation coefficient analysis. Meanwhile, the causal relationship was analyzed using multiple regression analysis.

Results: The skewness values for four variables in this study are between -1 and +1 that indicates normal distribution. The value of Cronbach’s alpha statistical test for measuring internal reliability is larger than 0.7 for all four variables. Therefore, four constructs exhibit good reliability that indicates the suitability of internal consistency. Next, the value of R-squared for model fit in this study is 0.675 that indicates a good model fit that explained 67.5% of variance in dependent variable. Multiple regression analysis indicates Attitudes (A), Subjective Norm (SN) and Perceived Behavioral Control (PBC) are significant in predicting the value of Intention (I) to select a career in halal food industry.

Conclusion: This study supported the hypothesis that indicates there is a positive and significant relationship of Attitude (A), Subjective Norm (SN) and Perceived Behavioral Control (PBC) towards Intention (I). The findings of this study add value to theoretical knowledge of career selection among university students. At the same time, this study provides guideline for government in developing better policy in cultivating interest among university students to be highly involved in the halal food industry.

Published: November 2021

Case:
A 32-year-old woman presented with worsening right anterior hip pain, reduced hip flexion strength, and passive range of motion during hip flexion. Magnetic resonance imaging of the hip demonstrated a prominent lesser trochanter and localized fluid signal intensity at the iliopsoas bursa. The patient underwent endoscopic iliopsoas bursectomy and lesser trochanterplasty, reporting improvement in all clinical outcome scores at 1-year follow-up.

Conclusion:
Lesser trochanter morphology should be evaluated in patients presenting with iliopsoas bursitis. In patients failing to respond to conservative management, endoscopic iliopsoas bursectomy and lesser trochanterplasty may address pain and functional limitations.
Postoperative Pyoderma Gangrenosum After Thoracolumbar Spinal Fusion with Instrumentation
Authors: Bellamy J. Taylor , Ananthakrishnan Dheera 
Published: November 2021

Case:
A 65-year-old man with scoliosis underwent posterior spinal fusion with instrumentation from T4 to pelvis and subsequently developed wound complications eventually diagnosed to be secondary to postoperative pyoderma gangrenosum (PPG). Once immunosuppressant medications were initiated, the wound gradually improved and went on to heal after a prolonged period of wound care.

Conclusion:
Postoperative PG is a challenging problem for the orthopaedic surgeon; a multidisciplinary approach is beneficial. Early recognition of the diagnosis is imperative to limit morbidity because debridements for a presumed infectious etiology are likely to exacerbate the disease through a process called pathergy.
