Published: July 2024

Metal hydrides are serious contenders for materials-based hydrogen storage to overcome constraints associated with compressed or liquefied H2. Their ultimate performance is usually evaluated using intrinsic material properties without considering a systems design perspective. An illustrative case with startling implications is (LiNH2+2LiH). Using models that simulate the storage system and associated fuel cell of a light-duty vehicle (LDV), we compared performance of the bulk hydrides with a nanoscaled version in porous carbon, (LiNH2+2LiH)@(6-nm PC). Using experimental material properties, the simulations show that (LiNH2+2LiH)@(6-nm PC) counterintuitively has higher usable gravimetric and volumetric capacities than the bulk counterpart on a system basis despite having lower capacities on a materials-only basis. Nanoscaling increases the thermal conductivity and lowers the desorption enthalpy, which consequently increases heat management efficiency. In a simulated drive cycle for fuel cell- powered LDV, the fuel cell is inoperable using bulk (LiNH2+2LiH) as the storage material but completes the drive cycle using the nanoscale material. These results challenge the notion that nanoscaling incurs mass and volume penalties. Instead, the synergistic nanoporous host-hydride interaction can favorably modulate chemical and heat transfer properties. Moreover, a co-design approach considering application- specific tradeoffs is essential to accurately assess a material’s potential for real-world hydrogen storage.

The cinnamalmalononitrile (CM) family of molecules can undergo a [2+2] photodimerization in the solid-state and generate photomechanical response. Derivatives exhibit two different crystal packing motifs: head-to-head (HH) in which the molecules stack with the phenyl rings on the same side of the stack, and head-to-tail (HT) in which the phenyl rings of adjacent molecules are on opposite sides. The [2+2] photodimerization is only observed for HT packing motif. Attempts to identify chemical substitution patterns that favor the reactive HT packing based on simple steric and electrostatic considerations fail to reliably predict crystal packing, and fluorination generated both motifs in more-or-less random fashion. Empirically, substitution at the 3-position favors HT packing while substitution at the 4-position favors HH packing. Computational modeling suggests that the tendency for HH or HT packing arrangements stems from complex many-body interactions with the rest of the lattice. Modeling with periodic density functional theory shows that interactions with the rest of the lattice also explain why the HT motif is photochemically active while the HH motif is inert. Chemical substitution can also affect the photomechanical work output, with a significant variation in work between HT polymorphs composed of different molecules. In order to obtain a reactive HT polymorph, the best strategy appears to entail placing a strong electron-withdrawing group at the 3-position of the phenyl, and we confirm that an HT polymorph of 3-trifluoromethyl-cinnamalmalononitrile is a highly photosalient crystal, with a predicted ideal work density of 40 MJ/m3.
Non-deterministic Dynamics in η-to-θ Phase Transition of Alumina Nanoparticles

Published: July 2024

Phase diagrams and crystallography are standard tools for studying structural phase transitions while acquiring kinetic information at the atomistic level has been considered essential but challenging. Here, we report a rare example of a statistical kinetics study, showing that the η-to-θ phase transition of alumina, unidirectional in bulk and retaining the crystal lattice orientation, occurs non-deterministically via an ergodic equilibrium via molten state, as observed for nanoparticles on bulk Al(OH)3 surface. The memory of the lattice orientation is lost. The rate of the interconversion was insensitive to the electron dose rate, and it is a thermal process with a small Gibbs free energy of activation. This non-deterministic kinetics should be a key feature of crystal nucleation occurring in high surface energy regions of bulk crystals.

Synthetic polymers—chemically versatile and affordable materials—are promising nanocarriers for the intracellular delivery of nucleic acids. Lipophilic polycations with incorporated hydrophilic co-monomers effectively complex and deliver bulky nu- cleic acid payloads such as plasmids (pDNA). The spatial distribution of lipophilic cations and neutral, hydrophilic repeat units governs the pDNA binding, serum stability, pDNA delivery efficiency, and cytocompatibility of polymer–pDNA complexes, 1 or polyplexes. Yet, investigators have focused predominantly on block and statistical copolymers while largely ignoring gradient copolymers, where the density of lipophilic cations diminishes gradually along polymer backbones. Seeking to obtain gradient copolymers that combine the colloidal stability of block copolymers with the high trans-fection efficacy of statistical copolymers, we synthesized length- and compositionally- equivalent gradient copolymers (G1–G3) via reversible addition fragmentation chain transfer polymerization (in addition to equivalent statistical (S) and block (B) copolymer references). We mapped microstructure-dependent differences in polymer–pDNA, pDNA loading per polyplex, pDNA conformational changes, and binding thermodynamics via static light scattering, circular dichroism spectroscopy, and isothermal titration calorime- try, respectively. B exhibited vastly different binding profiles compared to the other four copolymers while having the highest pDNA loading capacity. Further, we discovered that subtle modulation of gradient steepness is an effective strategy to negotiate trade- offs among pDNA delivery efficiency, cytotoxicity, and colloidal stability in serum. For instance, G1 overcame the colloidal instability of S polyplexes in serum, while maintaining comparable transfection efficiency. Similarly, G1 showed the highest TxV value (from Pareto front analysis), indicating that lipophilic cation distribution in copolymer microstructure promotes cell viability along with high transfection. Microstructural con- trasts did not elicit differences in complement activation, while S triggered the highest hemolysis. Our work demonstrates that the spatial distribution of lipophilic cations is an effective, albeit underutilized, design handle to improve the physical properties and biological performance of polymeric gene carriers.
Description of ion properties using molecular orbital energy levels
Authors: Doronin Sergey V.
Published: July 2024

The study reveals correlations between the parameters of ions and their HOMO and LUMO orbital energy level values. In particular, it demonstrates a clear correlation for the ion adsorption parameters on model electrodes: the aluminum oxide (0001) surface, graphene and Au (111) surface. Correlations are also ob-served for the parameters of ion binding to water and dimethyl carbonate molecules, which are often used as solvents. In addition, the dipole moment, polarizability and solvation energy of ions are well correlated with the values of the molecular orbital energies, and for anions a dependence on the oxidation potential is observed. The obtained descriptors make it possible to select ions with desired values for a specific problem. As an illustrative example, in this work we consider the problem of displacement of water molecules from the inner electric double layer by ions, which is one of the factors increasing the potential window in electrolytes of aqueous batteries. This approach can be applied in the rapidly developing field of aqueous electrolytes for battery or supercapacitor design, catalysis control through surface composition variations, as well as in studies of heavy metal ion binding to sorption materials.
An exploration of potentially reversible controls on millennial-scale variations in the slip rate of seismogenic faults: Linking structural observations with variable earthquake recurrence patterns
Authors: Cawood Tarryn , Dolan James
Published: July 2024

Paleoseismic studies show that faults within a fault system may trade off slip over time, with mechanically complementary faults displaying alternating fast- and slow periods. Each of these periods spans multiple seismic cycles, and typically involves ~20-25m of slip. This suggests that the relative strength (or tendency to slip) of individual faults varies, over time and displacement scales larger than those of individual seismic cycles. The mechanisms responsible for these strength variations must: affect rocks in the strongest portion of the fault (the brittle-ductile transition) as this likely controls the overall slip rate of the fault; be reversible (or able to be counteracted) on a cyclical basis; provide a negative feedback that operates to change the fault from its current state; and have a measurable effect on fault strength over a time or length scale that corresponds to the observed fast and slow periods of fault slip. In this paper, we systematically explore 19 potentially weakening and 11 potential strengthening mechanisms and evaluate them in light of these criteria. This analysis reveals a relatively small subset of mechanisms that could account for the observed behavior, leading us to suggest a possible model for fault strength evolution.

The research aims to formulate and evaluate the Metoprolol succinate buccal tablets in hypertension treatment. The Fourier transform infrared (FTIR) results depict no incompatibility between the drug and excipients. The study results of pre-compression parameters have excellent flow qualities and compressibility. The post-compression parameters show that the results are within the specified standard deviations. The swelling index reveals that the formulation F6 shows that the complete drug was released and the tablet integrity was maintained during the expected duration. Formulation F6 chitosan and Carbopol 934 were used in a ratio of 1:1, resulting in the release of the drug up to the 10th hour and completely. Therefore, formulation F6 was optimized and compared with the marketed product. Formulation F6 exhibited better drug release performance than the marketed product.

The study was undertaken to develop and characterize docetaxel-loaded lyophilized block co-polymeric micelles for cancer therapy treatment. The study demonstrates that micellar size, shape, zeta potential, and other characteristics of lyophilized polymeric micelles are appropriate; furthermore, because of the polymer's encapsulation and capacity to maintain the drug release, significantly reduces toxicity and adverse effects. Block co-polymeric micelles offer improved solubility and a high capacity for drug loading, perhaps enhancing the bioavailability. As per this research, the idea of employing block co-polymeric micelles to enhance the solubility of hydrophobic medications holds excellent promise as an intravenous drug delivery system. While the outcomes are encouraging, the docetaxel-loaded block co-polymeric micelles must be further evaluated for In-Vivo studies to check the targeted drug delivery.Bottom of Form

Published: July 2024

Recent approaches in regulatory perspectives for the registration of drugs in Southern states of India have been characterized by a focus on enhancing efficiency, transparency, and safety in the drug approval process. This involves the adoption of stringent regulatory frameworks aligned with international standards to ensure the quality, efficacy, and safety of pharmaceutical products. One significant development is the implementation of electronic submission systems for the registration of drugs, streamlining the application process and reducing administrative burdens for regulators and pharmaceutical companies. Additionally, there has been an emphasis on strengthening post-marketing surveillance mechanisms to monitor the safety and efficacy of drugs once they are in the market, enabling prompt identification and mitigation of potential risks or adverse reactions. Collaborative efforts between regulatory authorities, industry stakeholders, and healthcare professionals have also been encouraged to facilitate knowledge exchange and capacity building in regulatory compliance and pharmacovigilance. Overall, these recent approaches reflect a concerted effort to uphold public health standards and ensure access to safe and effective medications for the population of Southern states in India.

Published: July 2024

We attempted to establish a method for estimating methane sulfonic acid methyl or ethyl ester in the dabigatran etexilate Mesylate in bulk and pharmaceutical dosage form. Dabigatran is an anticoagulant used in deep vein thrombosis and lung thrombosis. Methane sulfonic acid and ethyl sulfonic acid are DNA ethylating agents and genotoxic. These compounds can be estimated using the GC MS method using Helium as a carrier gas, and the compounds are estimated to be at 79 and 400 masses. The 60% methanol is used as diluent and blank. The method is validated as per the procedures of ICH, and all the validation parameters are within the acceptable limit of the impurities guidelines, as stated in the Q4 section. The different batches were analyzed using the same technique, and no impurities were found; hence, the batches were passed.

Valiosos e indeseables: colaboración interdisciplinaria en el reconocimiento de insectos asociados a colecciones arqueológicas del Museo de La Plata (Argentina)
Authors: Hernández Matías , Teileche Thelma D. , Mariani Roxana , Igareta Ana
Published: July 2024

La conformación de equipos interdisciplinarios para el acondicionamiento de colecciones arqueológicas de museos suele contemplar la participación de arqueólogos, museólogos y conservadores pero es poco habitual que incorpore profesionales de otros campos de las ciencias naturales. Tal vez porque resulta poco claro cuál es el aporte concreto que éstos últimos pueden realizar a la labor o porque no se considera que el ámbito museográfico puede ser también ámbito de investigación interdisciplinario. La incorporación de entomólogos al equipo responsable de la puesta en valor de colecciones arqueológicas del Museo de La Plata (provincia de Buenos Aires, República Argentina) no solo contribuyó al diseño y puesta en marcha de un adecuado plan de manejo de los insectos dañinos detectado en sus depósitos sino que inauguró a nivel local una nueva línea de trabajo arqueoentomológico, cuyo foco está puesto en la revisión de colecciones que han permanecido por años en guarda en museos.

Published: July 2024

During the recovery period, the post-partum mother will experience psychological changes proposed by several theories, which divides the period of psychological adjustment for the post-partum mother through three phases, namely the taking-in phase, taking-hold phase, and letting go. The moms' emotional, intellectual, and behavioral disorders are triggered by their awareness of their culpability. Mothers must adjust to their new positions as they deal with new families with babies. Inadequately adapting to the post-partum period, mothers should get support from the family. This study aimed to determine the relationship between family support and the process of psychological adaptation (letting go) in primiparous post-partum mothers. This study sampled 33 primiparous post-partum mothers using a proportional random sampling technique. These involved primiparous post-partum mothers who lived with their families for 10-42 days and were willing to be respondents. The research used a questionnaire to analyze data. Data analysis using the Kolmogorov-Smirnov showed a p-value of 0.047 (p-value≤0.05). The results suggest that there is a relationship between family support and the process of psychological adaptation. Improving early screening for post-partum depression and increasing understanding of mothers and families can help reduce baby blues syndrome and post-partum depression in post-partum mothers.

Running speed in the form of sprinting is one of the most important abilities that can significantly define performance success in many sports. From the perspective of genetically inherited motor functions, running speed can be classified as a primary phylogenetic human movement, manifested in the form of a “threesegment model” consisting of speed, power, and coordination. By comprehensively analyzing the general and partial predictive contributions of dynamic-kinematic parameters of running, speed-power abilities, and morphological characteristics, on a sample of 80 boys aged 10-12 years, it can be concluded that regardless of the choice of criteria, achieved maximal speeds (KVMAX) or results in children’s athletic sprint over 50 meters (KT50m), the same or related predictor variables contributed to the explanation. The variable running time for 20m from a flying start (KTLS20m) has the greatest predictive contribution (β=0.83, p<0.001) to explaining both criteria, which may indicate the importance of conducting this test in the identification and selection for athletic sprint. Additionally, the selection of tests to assess speed-power abilities is extremely important for the identification and selection for athletic sprint. It can be concluded that tests of horizontal and vertical jumps are significant for identification, as well as tests for assessing neuro-muscular excitation. Tests for assessing continuous horizontal jump are also important, although there is an impression that, in boys aged 10-12 years, coordinatively simpler tests should be used. In the analysis of morphological characteristics, variables that significantly contributed to the explanation of criteria at a partial level were body height, back skinfold, and ankle diameter, indicating that in the identification of talented individuals, it should be considered that elite sprinters are characterized by light bones, optimal muscle mass, and low levels of subcutaneous fat tissue.

Published: July 2024

The purpose of this study is to explore the difficulties that emerged in the implementation of the play-centered curriculum practices of infant class teachers based on the play-centered childcare curriculum emphasized in the 4th standard childcare curriculum. To this end, a photovoice research method was conducted with 10 infant class teachers working at the national and public S daycare center in G, Gyeongsangbuk-do. The photovoice research method analyzed the data collected by the research participants as they spoke out while discussing together using photos taken directly by themselves, in the process of selecting, contextualizing, and categorizing them. The six subcategories of difficulties in the implementation of the play-centered curriculum practices process of infant class teachers in this study are play autonomy and creativity support, development level differences and social interaction, teacher roles and interventions, teacher support and resource utilization, safety and hygiene management, institutional and policy support. The final categories for this were expressed as difficulties in autonomous play implementation, difficulties in role and support, and difficulties in environmental management and policy management. This study which explored the difficulties experienced by implementing the play-centered curriculum practices process of teachers through the photovoice research method can be useful in improving the currently implemented childcare policy and childcare process. Therefore, it is expected to contribute to supporting infant class teachers' implementation of the play-centered curriculum practices.

Published: July 2024

This study aims to systematically assess the diagnostic utility of specific hematological parameters and indices in pediatric patients for the early and accurate diagnosis of COVID-19, thereby contributing to enhanced clinical management and diagnosis of children. The study evaluated the diagnostic potential of hematological and inflammatory markers in 90 pediatric patients, including 49 with COVID-19 and 41 without. It focused on complete blood counts, systemic immune-inflammatory index (SII, calculated as platelet count multiplied by neutrophil count divided by lymphocyte count), platelet to mean platelet volume ratio (PLT/MPV), neutrophil to lymphocyte ratio, platelet to lymphocyte ratio, C-reactive protein, and procalcitonin, comparing these markers between patients with and without COVID-19. COVID-19 positive patients exhibited higher hemoglobin levels and immature granulocyte percentages, along with lower total leukocyte, neutrophil, platelet counts, and procalcitonin levels (p-values: 0.02, 0.006, 0.01, 0.002, 0.007, and 0.01, respectively). The SII and PLT/MPV ratio were significantly lower in the COVID-19 positive group (p=0.01 and p=0.006, respectively), suggesting their potential diagnostic relevance. Receiver Operating Characteristic (ROC) analysis revealed that procalcitonin, PLT/MPV, and SII had comparable diagnostic utility, with area under the curve (AUC) values indicating moderate diagnostic accuracy (procalcitonin AUC: 0.65, p=0.013; PLT/MPV AUC: 0.67, p=0.004; SII AUC: 0.65, p=0.01). Our research highlights the PLT/MPV ratio and SII as breakthrough markers for early detection of COVID-19 in children, providing a significant advance in pediatric diagnostics and enhancing our ability to meet the challenges of the pandemic.

Prolonged use of computers and digital devices can lead to various physical and mental health problems. This study sought to assess computer and digital device ergonomics (CDDE) of designers, photographers, IT professionals, accountants and suppliers in several Bulgarian firms and to determine the visual (VS) and musculoskeletal (MS) symptoms reported by the respondents.
In the study, a survey was made, through a survey, using a Google Form. 42 participants were surveyed, within two weeks, in 3 age groups: up to 30 years, from 30 to 40 years and over 40 years. A significant proportion of employees reported various symptoms of VS and MS. The most affected parts of the body are identified: neck, arm/shoulder/wrist and waist. Special attention is paid to eye strain, and the symptomatology is most often related to visual symptoms, such as eye fatigue, eye pain, sensitivity to light, and others. The research covers significant issues related to health care and the importance of ergonomics in practice.

Preservice mathematics teachers will eventually become mathematics teachers and teach mathematics in schools to students. Therefore, it is important to assess the numeracy skills of preservice mathematics teachers to develop their numeracy skills, which will positively impact students once they start teaching in schools. This study aims to describe the numeracy skills of preservice mathematics teachers about numeracy, including how well they can explore mathematical concepts in problems related to numeracy. This study is a qualitative descriptive. The subjects of this study are 28 mathematics education students from the University of Mataram. The instruments used in this study are questionnaires and tasks containing numeracy problems using the Sasak cultural context. Data analysis employs descriptive qualitative analysis, which includes data transcription, categorization, data presentation, description of the numeracy skills of teacher candidates, and conclusion. The results show that, in general, students have not been able to distinguish between numeracy and mathematics. Additionally, students still face difficulties in designing numeracy-oriented learning, especially using the socio-cultural context
Robot-assisted salvage lymphadenectomy in prostate cancer with radiointerventional lymph note tagging

Prostate cancer is the second most common tumor in men worldwide, with lethality directly related to its staging. In general, radical prostatectomy represents the first line in the treatment of patients with prostate cancer, but even with improvements in diagnosis and advances in surgical techniques for the treatment of localized prostate cancer, it still occurs in up to 35% of cases. there will be biochemical recurrence over the years¹. Therefore, when this neoplasm recurs after the primary approach, treatment may vary according to its location and dissemination pattern. In cases of lymph node recurrence, adjunctive treatment with external radiotherapy is routinely indicated, associated or not with hormonal blockade.² However, in recent years, due to the advent of new imaging modalities with high sensitivity in cases of biochemical recurrence, the use of salvage lymphadenectomy has been proposed.² Thus, robotic salvage lymphadenectomy has emerged as an alternative to the treatment of patients with lymph node recurrence of prostate cancer. In this way, we seek to share, through a case report, the surgical technique of rescue lymphadenectomy with a lymph node marked by radiointervention.

Management of oncological pain in the elderly by the nursing team os a private hospital in the state os São Paulo
Authors: Soares Italo Lira , Pereira Dayane Vieira dos Santos
Published: July 2024

Background and objective: Elderly people represent 12% of the world's
population, with this number expected to double by 2050. Cancer is the main
public health problem in the world and is already among the four main causes
of premature death in most countries. In the elderly population, the prevalence
of pain is quite high. To guide the use of analgesics in the treatment of
pain, the WHO created the “analgesic ladder”, classifying opioids according
to their potency. In clinical practice, what often prevails is the individualized
knowledge of each nurse, which directs the type of medication prescribed. To
evaluate pain symptoms and pain management, using the Pain Management
Index, in hospitalized elderly patients. Methodology: Observational, quantitative
and retrospective study. The study population will be made up of the
number of hospitalized patients in 2021. To collect the information, access to
data in medical records was made. To investigate pain management, the Pain
Management Index was used, which analyzes analgesic potency in relation to
pain intensity. Results: 687 patients were selected, with 1178 pain scores recorded
during the studied period. 590 records had their pain reset in the first
reassessment, which took an average of 6h39 minutes. Regarding the PMI
calculation, most patients did not have their pain controlled. Conclusion: It is
necessary to standardize the instrument used in the research, so that it has
a theoretical-clinical basis, making the best analgesic choice for the patient,
since the majority of them do not have adequate control.
Accessory Splenic Mass Masquerading as Hepatocellular Carcinoma: A Diagnostic Dilemma

The spleen plays a pivotal role in our immune system by facilitating the proliferation and differentiation of lymphocytes and monocytes. Typically located in the left upper quadrant retroperitoneally, splenic tissue found outside of its usual position is termed ectopic spleen. When the tissue maintains its histological architecture and encapsulation and receives blood supply from splanchnic vessels, it is called an accessory spleen. Although it commonly presents near the splenic hilum or pancreatic tail, rare instances have been reported in the gastric, liver, gastrosplenic/lienorenal ligaments, as well as thoracic and gonadal regions. However, the case of an accessory spleen, mimicking a hepatic lesion in the right diaphragm represents a novel observation.
Mechanistic Insights into UV Spectral Changes of Pyruvic Acid and Pyruvate Part 1: Interaction with Water Molecules

Published: July 2024

We investigate how the UV spectra of pyruvic acid (PA) and pyruvate are impacted by interactions with water molecules. In particular, we would like to understand the mechanistic origin of the blue shift in the n →− π∗ transition. Pyruvic acid is the simplest α-keto organic acid and is common in the environment. We use density functional theory to optimize geometries to determine excitation energies and find that the excitation energies of the two main pyruvic acid conformers and pyruvate blue shift when interacting with 1 to 4 water molecules, both in vacuo and in a solvent. The excitation wavelength is blue-shifted by 0.9-9.2 nm when adding water molecules to the lowest energy conformer of PA. Calculations of the UV spectra of pyruvic acid (PA) and pyruvate are crucial for understanding the impact of the interactions with water molecules.
