Determinants of the profitability of credit unions in Ecuador
Authors: Parrales Choez Carlos Gabriel , Zambrano Farías Fernando José , Valls Martínez María del Carmen
Published: August 2024

This study analysed the behaviour of both economic and financial profitability of credit unions belonging to segment 1 in Ecuador, as well as its determinants. For this purpose, data from the financial statements of a sample of 30 credit unions between 2016 and 2022 were used by means of a multiple linear regression methodology using panel data with fixed effects after applying the Hausman test. The findings of this research showed that current liquidity and non-performing loans have a negative and significant effect on both economic and financial profitability while the past due portfolio has a positive and significant impact on the generation of profitability of the financial institutions under study. In addition, it was revealed that the rate of outflow absorption has a negative relationship with economic profitability but a positive relationship with financial profitability. Unlike previous research in the Ecuadorian context, this research is pioneering in presenting results that indicate that the determinants traditionally considered for nonfinancial institutions and banks are also valid for credit unions, even though they are organisations with different characteristics from the rest.

OBJECTIVE

The purpose of this study was to compare various sampling techniques and commercially available diagnostic tests for Cryptosporidium serpentis.

METHODS

A colony of 80 eastern indigo snakes (Drymarchon couperi) in human care was screened for the presence of C serpentis using endoscopic gastric mucosal biopsies for histologic and molecular analyses. At the time of endoscopic examination and biopsy, a cloacal swab, gastric swab, and gastric lavage sample were also collected. A C serpentis–specific probe hybridization quantitative PCR (qPCR) was performed on each sample. The gastric lavage sample was divided equally for direct microscopy, acid-fast stain, rapid qualitative immunochromatographic assay, direct fluorescent antibody, and 5 different PCR analyses. If a fecal sample was available at the time of endoscopic evaluation, it was also evaluated for Cryptosporidium oocysts by direct microscopy and acid-fast staining.

RESULTS

When comparing test results to histologic analyses, the sensitivity of the probe hybridization qPCR of gastric biopsy, gastric lavage, and gastric swab was 100% while the cloacal swab was 72%. When gastric lavage tests were compared, qPCRs outperformed the other tests.

CONCLUSIONS

Endoscopic biopsy for histologic and qPCR analyses is recommended for disease diagnosis, while gastric lavage or gastric swab samples for qPCR analysis are as sensitive as endoscopic biopsy for screening for the pathogen but cannot diagnose disease.

CLINICAL RELEVANCE

The results from this study allow the veterinary practitioner to select the most appropriate sample and testing methodology when evaluating an ophidian patient for gastric cryptosporidiosis.
Toxic Effects of the Trap Crop Solanum sisymbriifolium on the Hatch and Viability of Globodera pallida
Authors: Schulz Lindsay , Popova Inna , Dandurand Louise-Marie
Published: August 2024

Globodera pallida, the pale cyst nematode, is a quarantined potato pest first found in Idaho in 2006. The containment and eradication of this economically devastating pest has been the focus of control since its discovery. Globodera pallida survives for 30+ years in soil and can cause up to 80% yield loss in susceptible potato varieties. Soil fumigants have been key to eradication efforts but many have been banned. Therefore, new control methods are needed. Solanum sisymbriifolium induces hatching but limits G. pallida reproduction and can be used as an alternative control measure. However, as S. sisymbriifolium has little economic value as a crop and its seeds are largely unavailable, it has not been widely adopted by potato producers. There is evidence that this plant kills the nematode by producing toxins, although this is poorly understood. Liquid–liquid extraction of S. sisymbriifolium leaf and stem tissues by hexane and 1-butanol reduced hatch by 49.5%, and 68.3%, respectively, compared with the potato root diffusate control. Many chemicals may be responsible for this toxic effect, including steroidal glycoalkaloids produced by plants in the Solanaceae family. The discovery of novel chemistries for nematicide development would be valuable for potato cyst nematode control.

Authors: Zhou Li
Published: August 2024

Biomass-derived biochar has gained significant attention due to its unique properties and potential applications in various fields, including asphalt pavement engineering. However, there has been no comprehensive review to date that systematically examines the state-of-the-art research on biochar utilization in asphalt pavements, identifies the key knowledge gaps, and provides recommendations for future research directions. This review aims to fill this gap by providing a novel and critical analysis of the sources and production methods of biochar, the techniques for modifying and characterizing its properties, and its recent applications as an asphalt binder modifier, asphalt mixture additive, and stormwater filter material. The review employs a systematic literature search and analysis methodology, using scientific databases such as Web of Science and Scopus, and keywords related to biochar, asphalt, pavement, and environmental and economic aspects. The selected studies are reviewed and synthesized to identify research gaps, challenges, and future directions, with a focus on the technical, environmental, and economic feasibility of biochar utilization in asphalt pavements. The review also examines the life cycle assessment, carbon sequestration potential, and cost-benefit analysis of biochar utilization. The novelty of this review lies in its holistic approach to assessing state-of-the-art knowledge and its identification of key research needs and opportunities for advancing this emerging field. The review aims to provide valuable insights and recommendations for researchers, practitioners, and policymakers interested in leveraging the benefits of biochar for sustainable and high-performance asphalt pavements.

What happens to macromolecules in vivo? What drives structure-activity relationship and in vivo stability for antibody-drug conjugates (ADCs)? These interrelated questions are increasingly relevant due to the re-emerging importance of ADCs as an impactful therapeutic modality and the gaps that exist in our understanding of ADC structural determinants that underlie ADC in vivo stability. Complex macromolecules, such as ADCs may undergo changes in vivo due to their intricate structure as biotransformations may occur on the linker, the payload and/or at the modified conjugation site. Furthermore, dissection of ADC metabolism presents a substantial analytical challenge due to the difficulty in identification or quantification of minor changes on a large macromolecule. We employed immunocapture-LCMS methods to evaluate in vivo changes in drug-antibody ratio (DAR) profile in four different lead ADCs. This comprehensive characterization revealed that a critical structural determinant contributing to ADC design was the selection of the linker as the competition between the retro-Michael deconjugation and thio-succinimide hydrolysis reactions resulted in superb conjugation stability in vivo. These data, in conjunction with additional factors, informed the selection of AZD8205, a B7-H4-directed cysteine-conjugated ADC bearing a novel topoisomerase I inhibitor payload, with durable DAR, currently being studied in the clinic for the potential treatment of solid malignancies (NCT05123482). These results highlight the relevance of studying macromolecule biotransformation and elucidating the ADC structure-in vivo stability relationship. The comprehensive nature of this work increases confidence in our understanding of these processes. We hope this analytical approach can inform future development of bioconjugate drug candidates.
From new thermodynamics to classical mechanics
Authors: Ni Henmei
Published: August 2024

The laws of classical mechanics are rebuilt in the frame of new thermodynamics. Heat is the sum of kinetic energy, system work, and system potential of gas, while force is the linear gradients of heat variation. Exporters and importers of force are evident in terms of exotherm and endotherm. Temperature and volume gradients create asymmetric forces driving rotation and spin (self-rotation). It verifies that force transfer doesn’t need a medium. As an outstanding achievement, a succinct and general equation is derived to predict the equilibrium distance of molecular interaction: L_e=∛((3π^(α-1) m_A g)/(4N_A RT)), without using any assumption, such as van der Waals force and dispersion force. In addition, the origins and attributes of repulsion and attraction are disclosed. Predicting results are applausive. For example, at 298 K, Le for N2, O2, and CH4 are 3.11, 3.11, and 3.68 Å, comparable to the data adopted in MD simulations of the literature. All these results indicate that the world is created by evaporation (sublimation) – condensation. It is believed that all objects, from tiny atoms to giant objects like planets, are thermal equilibrium systems. The new thermodynamics can describe them from the internal structure to the outer behaviors.
Reference-Free Thio-Succinimide Isomerization Characterization by Electron-Activated Dissociation
Authors: Yang Junyan , Yuan Jiaqi , Huang Yue , Rosenbaum Anton
Published: August 2024

Rationale Isomerism can be an important aspect in pharmaceutical drug development. Identification of isomers can provide insights into drug pharmacology and contribute to better design of drug molecules. The general approaches to differentiate isomers include Fourier-transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), and circular dichroism. Although proven effective, a commonly used method to differentiate isomers is chromatography coupled with mass spectrometry (MS). Notably, MS is routinely applied in leucine and isoleucine differentiation to facilitate protein sequencing. This work focuses on isomer differentiation of widely applied thio-succinimide structure bridging the antibody backbone and linker-payload of antibody-drug conjugates (ADCs). The hydrolysis of thio-succinimide stabilizes the payload-protein structure while generating a pair of constitutional isomers: thio-aspartyl and thio-isoaspartyl. Methods This paper introduces a hybrid method using ligand binding assay (LBA) and liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) to reveal isomerization details of thio-succinimide hydrolysis over time in plasma samples incubated with ADC. By applying two orthogonal fragmentation methods, collision-induced dissociation (CID) and electron-activated dissociation (EAD), this pair of isomers showed different MS/MS spectra. This observation enables a unique approach in distinguishing thio-succinimide hydrolysis isomers. Results We observed signature R1+Thio+57 , R2+Succ+H2O-57 and R2+Succ+H2O-44 (Succ = succinate) fragment ions that differentiated thio-aspartyl and thio-isoaspartyl isomers using EAD. A newly discovered R2+ThioSucc+H2O-44 ion also served as additional evidence that further supported our findings. Conclusions This study is a first-to-date identification of thio-succinimide hydrolysis isomers without using synthesized reference materials. This approach should be applicable to all thio-succinimide-linked molecules. Correct identification of thio-succinimide hydrolysis isomers may eventually benefit the development of ADCs in the future.
Bulky phosphine ligands promote palladium-catalysed protodeboronation
Authors: Ser Cher Tian , Hao Han , Pablo-García Sergio , Jorner Kjell , Li Shangyu , Pollice Robert , Aspuru-Guzik Alán
Published: August 2024

The Suzuki-Miyaura cross-coupling reaction is plagued by protodeboronation, an undesirable side reaction with water that consumes the boronic acid derivatives required for the cross-coupling reaction. Meticulous mechanistic studies have previously established protodeboronation to be highly sensitive to the nature of the boronic reagent and reaction conditions. Particularly, the presence of bases, which are essential for the Suzuki-Miyaura coupling, is known to catalyse protodeboronation. However, protodeboronation catalysed by palladium-phosphine complexes, the benchmark catalyst system for Suzuki-Miyaura cross-coupling, has been largely overlooked. We demonstrate, using automated high-throughput experimentation, comprehensive computational mechanistic analyses and kinetic modelling, that protodeboronation is accelerated by palladium(II) complexes bound to bulky phosphine ligands. While sterically hindered ligands are typically used to facilitate difficult cross-couplings, these ligands can instead paradoxically impede cross-coupling product formation, requiring careful and judicious consideration when choosing ligands for Suzuki-Miyaura cross-couplings.
Effects of Anion Size, Shape, and Solvation in Binding of Nitrate to Octamethyl Calix[4]Pyrrole
Authors: Terry Lane M. , Foreman Madison M. , WEBER J. Mathias
Published: August 2024

We present cryogenic ion vibrational spectroscopy of complexes of the anion receptor octamethyl calix[4]pyrrole (omC4P) with nitrate in vacuo. We compare the resulting vibrational spectrum with that in deuterated acetonitrile solution, and we interpret the results using density functional theory. Nitrate binds to omC4P through H-bonds between the four NH groups of the receptor and a single NO group of the nitrate ion. The shape of the ion breaks the C4v symmetry of the receptor, and this symmetry lowering is encoded in the pattern of the NH stretching modes of omC4P. We compare the spectrum of nitrate-omC4P with that of chloride-omC4P to discuss effects of ion size, shape, and solvent interaction on the ion binding behavior.
A Broadly Applicable Strategy to Aminate Azines Enabled by Electronically Tuned Phosphine Reagents.
Authors: Liu Ren-Rong , Levy Jeffrey N. , McNally Andrew
Published: August 2024

We describe a strategy for aminating pyridines and other azines via phosphonium salt intermediates. Precisely tuning the electronic properties of the phosphonium ion was key for C–N bond formation via an SNAr-halogenation, SNAr-amination sequence. The process accommodates a wide range of amine classes and pyridine coupling partners and is viable for applications such as late-stage amination of complex pharmaceuticals and fragment-fragment coupling reactions. The capacity to rapidly modify the structure of the phosphine reagent was decisive and is a valuable feature in pseudohalide design.

Abstract
Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on glucosyl hesperidin (GH) as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF, which is produced from hesperidin and dextrin by enzymatic reactions, is a powder consisting mainly of monoglucosyl hesperidin (MGH) and unreacted hesperidin (flavonoid), which account in total for up to 92.8% (on dry basis) of the product. The applicant proposed to use the NF in specific drinks and food supplements leading to a maximum intake of up to 364 mg per day for adults. The target population is the general population, except for food supplements for which the proposed target population is children from 1 year onwards and adults. Taking into consideration the composition of the NF and the proposed uses, the consumption of the NF is not nutritionally disadvantageous. There are no concerns regarding genotoxicity of the NF. Based on a 90‐day oral toxicity study conducted with the NF, the Panel considers the NOAEL at the mid‐dose group, i.e. ~ 1000 mg/kg body weight (bw) per day. By applying an uncertainty factor of 200, the resulting intake providing sufficient margin of exposure for humans would be 5 mg/kg bw per day. The available human intervention studies did not report clinically relevant changes in haematological or clinical chemistry parameters following the administration of GH/MGH at supplemental doses of up to 3 g/day for 12 weeks. Overall, the Panel considers that the margin of exposure (~ 200) between the intake of the NF at the proposed uses and use levels and the NOAEL from the 90‐day study is sufficient. The Panel concludes that the NF, glucosyl hesperidin, is safe for the target population at the proposed uses and use levels.
VICTIMOLOGICAL PREVENTION OF CRIMES COMMITTED WITH THE USE OF INFORMATION (DIGITAL) TECHNOLOGIES

Published: August 2024

The article presents the general characteristics of victimological prevention of crimes committed using in-formation (digital) technologies. The authors emphasize that the study of criminal law and criminological features of digital crime is justified and necessary at the present stage of development of society and the state. The relevance of the research is due to the fact that the modern world is more focused on the transi-tion to the digital space. And since modern crime actively uses information (digital) technologies for its criminal purposes, a law enforcement officer engaged in combating digital crimes needs theoretically grounded research on this topic.
The purpose of this work is to reveal the victimological features of the prevention of certain types of digital crimes, as well as the study of criminologically significant characteristics of modern digital crime and the development on this basis of key measures aimed at preventing crimes committed in the infor-mation space.
In this study, the authors focus on the basics of victimological prevention of digital crime. The article discusses what basic measures should be taken by citizens to protect themselves from becoming a victim of a digital (cyber) crime. The prevalence of the use of modern digital technologies is beyond doubt, and a person using ITT can easily become a victim of cybercrime or simply suffer due to the lack of basic rules of digital security. In this regard, the basics of victimological prevention are an important component of the prevention of digital crime.
This study is intended for researchers interested in the issues of criminal law counteraction to crimes committed using information (digital) technologies.
