Early use of targeted blood patch in spontaneous intracranial hypotension presenting with bilateral subdural hematomas and acute infarcts
Authors: Shahzad Muhammad , Ashraf Mohammad , Muquit Samiul
Published: January 2025

Background:

Spontaneous intracranial hypotension (SIH) is a rare but important condition characterized by cerebrospinal fluid (CSF) leakage, typically presenting with postural headaches. In severe cases, SIH can result in subdural hematomas (SDHs), brain herniation, and acute infarcts. The 2023 SIH guidelines recommend starting with nontargeted epidural blood patches as the initial treatment, with up to two attempts before considering a targeted patch. Nontargeted patches are effective in most cases by distributing blood widely in the epidural space. However, in rapidly deteriorating patients, targeted blood patches may be necessary, especially when a specific leak site has been identified. This report highlights the importance of timely, targeted interventions in severe SIH cases.

Case Description:

A 34-year-old male presented with a 6-month history of worsening headaches, impaired mobility, and stupor. On admission, his Glasgow Coma Scale was 12, which rapidly deteriorated to 5. Imaging revealed bilateral chronic SDHs, cerebellar tonsillar herniation, and signs of intracranial hypotension despite no history of trauma or anticoagulant use. Initial surgical evacuation of the hematomas failed to improve the patient’s neurological status. Subsequent magnetic resonance imaging and computed tomography myelogram identified a CSF leak at the T12 level. Given the patient’s critical state and rapid neurological decline, we opted for a targeted epidural blood patch at the L1/2 level. This intervention led to significant clinical improvement, with follow-up imaging demonstrating a reduction in the subdural collections and resolution of the leak. The patient fully recovered and remained asymptomatic at a 6-month follow-up.

Conclusion:

This case highlights the need for flexibility in SIH management, particularly in severe cases with acute neurological decline. While nontargeted blood patches are typically recommended, early use of a targeted patch when imaging identifies the leak can lead to faster resolution and improved outcomes. Personalized treatment strategies are essential for managing complex SIH presentations and preventing further neurological complications.
The epidemiology of motorcycle-related acute traumatic brain injury: The NOMADEN study
Authors: Nugroho Aryandhito Widhi , Masrika Nur Upik En
Published: January 2025

Background:

Although persisting to be a public health hazard in Indonesia, motorcycle-related traumatic brain injury (TBI) due to road traffic accidents (RTA) lacks comprehensive national data. We aim to study the epidemiological pattern of motorcycle-related TBI and analyze the determinants related to mortality in the only neurosurgical center in the rural province of North Maluku, Indonesia.

Methods:

Using the North Maluku Database in Neurosurgery register, information regarding age, sex, health insurance, alcohol use, point of referral, degree of severity, brain computed tomography abnormalities, helmet use, surgery, injury-to-admission time (IAT), and relationship to the motorcycle were obtained from patients admitted to Chasan Boesoirie General Hospital, Ternate, in 2021–2022. Multivariable logistic regression analysis was performed to investigate associations with in-hospital mortality.

Results:

Of all RTA-related TBI patients (n = 353), 91.8% (n = 324) were caused by motorcycle collision (mean age ± standard deviation of 30.5 ± 16.7 years old). The majority were motorcyclists (66.7%), male (64.8%), IAT >4 h (55.9%), financed by non-Jaminan Kesehatan Nasional mechanism (66.4%), not under alcohol influence (78.4%), referred from Ternate (55.2%), and suffered mild TBI (75%). Thirty patients (9.3%) succumbed to death. Moreover, 9.3% and 91.2% were ≤17 years old and helmetless. Glasgow coma scale and IAT were significantly associated with in-hospital mortality (odds ratio [95% confidence interval]: 0.58 [0.49–0.68] and 5.44 [1.00–30.34], respectively).

Conclusion:

The young and productive males dominated the motorcycle-related TBI patients in North Maluku. Poor compliance with road traffic laws, as demonstrated by a considerable proportion of underage, alcohol-intoxicated, and helmetless patients, necessitated prompt actions from all related elements.

Authors: Severina Y.D. , Shakirov V.A. , Takaishvili L.N.
Published: January 2025

This study focuses on the relevance of modeling the long-term development of energy systems in the context of the energy transition. The comparative analysis of software products for the modeling of energy systems and complexes is presented. Open source software such as SpineOpt, PyPsa, Switch, TEMOA, and TIMES are discussed in more detail. Based on this comparative analysis, SpineOpt is selected for further use as it is most feature-rich. The use of SpineOpt is considered in modeling the long-term development of the energy system of Novikovo located on the Tonin-Aniva peninsula in the Sakhalin region. An overview of the energy system, outline of plausible development options, and chosen key technologies are provided. The time frame of modeling extends to 2050 with multiple scenarios of development of the area considered. The scenarios differed in the constraints imposed on CO2 emissions and new capacity additions of renewables. For each scenario, the model produced the optimal dynamics of evolution of the electricity generation mix, along with estimates of costs, greenhouse gas emissions, and hydrogen and germanium production volumes. Total CO2 emissions during the modeled timespan, which extended to 2050, were about 946 thousand tons under the most stringent constraints, and 2,458 thousand tons under moderate ones. At the same time, capital expenditures for the construction of energy facilities amounted to $51.6 million and $45.8 million, respectively. The solutions resulting from modeling enable identifying the most promising areas for development and technologies to be adopted.

Published: January 2025

Machine Learning Force Fields (MLFFs) promise to enable general molecular simulations that can simultaneously achieve efficiency, accuracy, transferability, and scalability for diverse molecules, materials, and hybrid interfaces. A key step toward this goal has been made with the GEMS approach to biomolecular dynamics [Sci. Adv. 10, eadn4397 (2024)]. This work introduces the SO3LR method that integrates the fast and stable SO3krates neural network for semi-local interactions with universal pairwise force fields designed for short-range repulsion, long-range electrostatics, and dispersion interactions. SO3LR is trained on a diverse set of 4 million neutral and charged molecular complexes computed at the PBE0+MBD level of quantum mechanics, ensuring a comprehensive coverage of covalent and non-covalent interactions. Our approach is characterized by computational and data efficiency, scalability to 200 thousand atoms on a single GPU, and reasonable to high accuracy across the chemical space of organic (bio)molecules. SO3LR is applied to study units of four major biomolecule types, polypeptide folding, and nanosecond dynamics of larger systems such as a protein, a glycoprotein, and a lipid bilayer, all in explicit solvent. Finally, we discuss the future challenges toward truly general molecular simulations by combining MLFFs with traditional atomistic models.

Authors: Ito Shusuke , Muraoka Koki , Nakayama Akira
Published: January 2025

The design of organic molecules lies at the heart of solving numerous chemistry-related challenges, necessitating effective collaboration between human intuition and computational power. This study demonstrates how general-purpose Large Language Models (LLMs) can facilitate the design of molecules, leveraging feedback from empirical knowledge through natural language. We used this approach to design organic structure-directing agents (OSDAs) that guide the crystallization of zeolites. In our computational workflow, the LLM proposes OSDA candidates that are evaluated by empirical knowledge and atomistic simulation. Feedback is then provided to the LLM in natural language to refine subsequent proposals, thus progressively enhancing the proposed OSDAs and promoting the exploration of chemical space. The predicted candidates encompassed experimentally validated OSDAs, structurally analogous ones, and novel ones with superior affinity scores, underscoring the robust capability of the LLM. The human-machine collaboration, utilizing natural language as the communication interface, holds potential for application in other molecular design tasks, including drug design.

Published: January 2025

The biological impact of microplastics in human food and water sources is largely unknown, and drinking water sources are not exempt from microplastic contamination. Here, we demonstrate a streamlined approach for capturing, quantifying, and identifying microplastics in drinking water. We present an analytical workflow termed Silicon Nanomembrane Analysis Pipeline (SNAP) that takes advantage of novel silicon nitride nanomembranes which enable a significant “concentration factor," consolidating suspended particles into a planarized observation area for individuated, quantifiable, and multimodal particle analysis on the same substrate. Drinking water samples sourced in the Rochester, NY region were collected and analyzed using SNAP. Particles in each sample were characterized by optical and electron microscopy, Raman spectroscopy, and various identified constituents were quantified in proportion to total captured particles.
On the Thermodynamics of Water Displacement from Binding Sites and its Contributions to Supramolecular and Biomolecular Affinity
Authors: Setiadi Jeffry , Biedermann Frank , Nau Werner , Gilson Michael K.
Published: January 2025

The role of water displacement in noncovalent binding has been debated in the fields of supramolecular chemistry and drug design. We use molecular dynamics simulations of idealized host-guest systems to address the long-standing controversy of whether water is merely a bystander or an actual driver of noncovalent binding in aqueous solution. To isolate hydration effects, we consider a pseudo-hard-sphere guest binding to a series of cucurbit[8]uril-based host models whose energetic interactions with water vary widely. The computed free energy cost of displacing water from binding sites ranges from 0 to +37 kcal/mol, strongly influencing binding affinities. However, neither water density nor excess chemical potential reliably indicates the thermodynamic favorability of cavity water. These results support the concept that "unfavorable" binding site water contributes to high-affinity binding and resolve the paradox of stable but thermodynamically unfavorable cavity water. This work provides insights into the nature of the hydrophobic effect in molecular recognition and offers a framework for understanding water's role in binding across various host-guest and protein-ligand systems.
In Silico Analysis of 6-Gingerol for Antifungal Efficacy Against Candida albicans
Authors: AHMED TANZIM
Published: January 2025

Candida albicans, a major fungal pathogen, poses significant challenges due to antifungal resistance, particularly in immunocompromised individuals. Natural compounds, such as 6-gingerol, derived from Zingiber officinale (ginger), have gained attention for their therapeutic potential. This study investigates the antifungal activity of 6-gingerol against C. albicans using in silico approaches, including molecular docking, ADMET profiling, and interaction analysis. Molecular docking results demonstrated that 6-gingerol exhibits potential inhibitory interactions with key fungal targets N-myristoyltransferase and Sterol 14-alpha demethylase, facilitated by hydrogen bonding and hydrophobic forces. ADMET analysis revealed favorable pharmacokinetic and safety profiles, including low toxicity, supporting its potential as a natural antifungal agent. These findings suggest that 6-gingerol, a bioactive compound from ginger, holds promise for further exploration in antifungal drug development. Experimental assessment using in vitro and in vivo experiments is advised to verify its effectiveness and suitability for clinical applications.

Published: January 2025

Perovskite solar cells (PSCs) have developed rapidly in the last decade, primarily because of improvements in their photovoltaic (PV) performance. However, methods of characterization and analyses for PSCs remain immature, mostly because of the complex multilayered PSC structure. The sandwiched structure of i-type perovskite photoabsorbers having both p-type hole transport materials (HTMs) and n-type electron transport materials (ETMs) facilitates charge separation in the perovskite photoabsorber and thus plays a crucial role in developing efficient PSCs. However, this structure forms multiple heterointerfaces, which more easily undergo structural changes than the bulk and are difficult to characterize independently. Herein, we propose a method for differentiating the bulk and heterointerface properties in PSCs in terms of their carrier dynamics by using excitation power dependence on photoluminescence lifetime (EPD-PLL) measurements. This method exploits the intrinsically different carrier mobility behavior of the PSC components; specifically, the carrier mobilities within perovskite photoabsorbers are significantly higher (by over three orders of magnitude) than those in carrier-transport materials (CTMs). Strong excitation causes carrier accumulation in the CTM bulk, resulting in time-dependent carrier injection, which could be indicative of the bulk CTM properties. In contrast, weak excitation leads to time-independent carrier injection from the perovskite to CTMs, correlating with heterointerface properties. Hence, EPD-PLL measurements differentiate carrier dynamics between the CTM bulk and heterointerfaces. The method was tested by investigating the thermal degradation mechanism of typical Spiro-OMeTAD-based PSCs, revealing that the contribution of heterointerface deterioration by thermal stress can be neglected. The degraded PSCs had unusual PV properties, unlike those of fresh PSCs, and the EPD-PLL results confirmed these unusual properties, facilitating effective PSC characterization. The proposed method can be applied to the characterization of other PSCs, contributing to the further development of PSCs by addressing a missing point: the characterization and analysis of PSCs.
Predator-prey behavior of droplets propelling through self-generated channels in crystalline surfactant layers.
Authors: Singh Priyanshu , Korevaar Peter A.
Published: January 2025

Motile droplets provide an attractive platform for liquid matter-based applications and protocell analogues displaying life-like features. The functionality of collectively operating droplets increases by the advance of well-designed (physico)chemical systems directing droplet-droplet interactions. Here, we report a strategy based on crystalline surfactant layers at air/water interfaces, which sustain the propulsion of floating droplets and at the same time shape the paths for other droplets attracted by them. First, we show how decylamine forms a closed, crystalline layer that remains at the air/water interface. Second, we demonstrate how aldehyde-based oil droplets react to decylamine in the crystalline layer by forming an imine, causing the droplets to move through the layer while leaving behind an open channel (comparable to “Pacman”). Third, we introduce tri(ethylene glycol) monododecylether (C12E3) droplets in the crystalline layer. Whereas the crystalline layer suppresses the motion of the C12E3 droplets, the aldehyde droplets create surface tension gradients upon depletion of surfactants from the air/water interface, thereby driving Marangoni flows that attract the C12E3 droplets as well as the myelin filaments they grow: Causing the C12E3 droplets to chase, and ultimately catch, the aldehyde droplets along the channels they have created, featuring a predator-prey analogy established at an air/water interface.
Photocatalytic Degradation of Ampicillin Under Sunlight Using a Boron Cerium and Silver Ternary Doped Titanium Dioxide Catalyst Synthesized via the EDTA-Citrate Method
Authors: Mishra Yash , Mahalingam Hari
Published: January 2025

Nowadays, we can see that in river water, traces of antibiotics can be found, which is an emerging problem. Also, pharmaceutical companies' wastewater contains antibiotic traces present in it in a significant amount which makes it an excellent experimental domain to work upon. Which is very harmful if taken by humans without its treatment, so to treat it as early as possible is very necessary, else the bacteria emerging in that water will be converted to superbugs and then curing the disease from that bacteria will be exceedingly difficult as they have resistive power to that antibiotic. For that, we have prepared a tri-doped photocatalyst by doping boron cerium and silver in a titanium dioxide structure. It can work under sunlight light because the presence of silver in this boron amount is increased so that it can satisfactorily degrade antibiotics. Cerium is for water disinfection in the further catalyst. Its amount was also increased. Then the characterization analysis was performed with the help of DLS analysis with the help of a nanoparticle size analyzer, and we got particle size in the range of 115 to 600 nanometer XRD analysis. We got a band gap Of 2.3 to 2.4 electron Volt.BET surface area analysis showed us a surface area of about 25 m2/g.So instead of the UVA lights now, it was performed under the sunlight and the degradation percent was increased significantly to approx 70 percent.

Published: January 2025

Phosphorodiamidate Morpholino Oligonucleotides (PMO) have been well established in the treatment of muscular dystrophies with five drugs approved so far on this scaffold. However, the literature data on synthetic methodology for PMOs is very limited in the public domain. In this report, micromole scale synthesis of PMO has been achieved with improved yield and HPLC purity. Casimersen (Amondys 45), an FDA approved drug for treatment of Duchenne Muscular Dystrophy (DMD) was selected as the standard sequence for screening various conditions. Optimization of different reaction conditions revealed that 1:1 salt of 4-cyanopyridine and methane sulphonic acid served as an efficient deblocking agent, Ramage Chemmatrix resin with sarcosine linker-loading was a suitable solid support and 1,3-Dimethyl-2-imidazolidinone (DMI) was the appropriate solvent. The compound was purified by reverse phase HPLC in Trityl ON mode and characterized by MALDI-TOF. Conjugation of PMO with stearic acid, docosanoic acid, and a phosphorothioate based linker has been shown to significantly enhance serum binding properties while avoiding adverse effects such as hemolysis or immunostimulation. These modifications not only improve the bioavailability of PMOs but also suggest potential strategies for optimizing their pharmacokinetic profiles. The minimal immune activation observed compared to traditional PMOs underscores their promising safety and efficacy in clinical applications. However, the varying rates of dialysis among different conjugates indicate a complex interaction with albumin, highlighting the need for further detailed investigation in this area.

Authors: Sévery Laurent , Nicolas Emmanuel , Mifleur Alexis , Cantat Thibault
Published: January 2025

Despite their widespread use as reductants, the thermodynamic hydricities of hydrosilanes have not been determined experimentally. We report the hydricities of three triarylsilanes, determined by a combination of hydride-exchange reactions and electrochemical measurements of the corresponding silylium cations. The hydricities for Xyl3SiH (89.0 kcal·mol-1), Mes3SiH (86.6 kcal·mol-1), and PEMP3SiH (80.5 kcal·mol-1) were estimated from the one-electron reduction potentials of the silylium ions in 1,2 difluorobenzene and are higher than previously reported values obtained by calculations. The reaction of [PEMP3Si][B(C6F5)4] with cycloheptatriene (CHT) in 1,2 difluorobenzene/C6D6 (4:1) attained an equilibrium (K ≈ 1.3), indicating similar hydricities for CHT and PEMP3SiH.

Magnetic resonance imaging (MRI) is a widely used diagnostic tool, yet it exhibits inherent low sensitivity that necessitates the use of contrast agents to improve the quality of MRI scans. Gadolinium-based contrast agents, and more recently manganese-based agents, have been used in pre-clinical and clinical applications due to their relaxation properties. Herein, we report a series of chelators based on the 2,11-diaza[3.3](2,6)pyridinophane macrocycle, which was chosen since its rigidity was hypothesized to favorably enhance the relaxivity of the Mn2+ complexes. The synthesized chelators were used to probe the effect of coordination number and choice of pendant arms on the efficiency of the corresponding Mn MRI contrast agents, and two lead compounds, [Mn(TE-1)]+ and [Mn(TE-4)], were identified. [Mn(TE-1)]+ has a relaxivity of 3.6 mM-1 s-1 (1.4 T, 33 ºC), comparing well to clinically established Gd-based contrast agents. By employing the 52Mn radioisotope, a positron emission tomography (PET) radiotracer, in vivo PET imaging experiments, along with T1-weighted MRI studies, reveal that [Mn(TE-4)] shows rapid clearance with significant contrast enhancement in the kidney and bladder, indicating primarily renal clearance. By comparison, the lipophilicity of [Mn(TE-1)]+ promotes a mixed, biliary-renal excretion. Importantly, both compounds show no appreciable degradation in urine metabolites. Overall, the in vivo performance of [Mn(TE-4)] lends promise to its potential development either as an MRI contrast agent or PET imaging agent. The hepatobiliary clearance of [Mn(TE-1)]+ provides opportunities for blood pool imaging via MRI, with low-temperature radiolabeling conditions compatible with a range of biologics and potential use for immuno-PET imaging.
Beyond LLTO-based Perovskite Electrolytes for Stable Metal All-Solid-State Batteries
Authors: Biby Ahmed , Ali Basant , Musgrave Charles
Published: January 2025

Perovskite-type electrolytes (PTEs) have good room-temperature ionic conductivity but suffer from poor stability against metal anodes, limiting their use in metal all-solid-state batteries. Researchers often focused on doping/alloying PTEs, overlooking thorough investigation of the main framework, namely La, Ti, and O. Herein, we studied the composition-stability relationship of PTEs focusing on their computational thermodynamic, electrochemical, migration barriers, and mechanical properties. The studied PTEs are unsuitable for metal sodium batteries without modifications to reduce migration barriers. LLHfO and LLZrO show promising metastability against metallic Li anodes, though their migration barriers are higher than LLTO. Nonetheless, LLZrO demonstrated partial mechanical instabilities. Mechanical analysis of LLHfO exhibited balanced mechanical properties. Hence, LLHfO proved to be a promising Li-metal-metastable alternative to the archetypal LLTO with enhanced overall performance metrics.
Scalable manufacturing of radiation-tolerant potentiometric electrodes: A systematic transition from laboratory to semi-automated fabrication
Authors: Zhao Bingyuan , Yermembetova Aiganym , Tsai Benson , Huang Jialong , Wei Alexander
Published: January 2025

A “lab-to-fab” transition is described that enables the semi-automated production of thin-film potentiometric pH electrodes, designed for use in sterile single-use bioreactors. Manual methods of materials deposition and film casting are replaced with spray coating on a moving web and the production of membranes with a programmable dispenser operating at constant rates. These provide a greater degree of control over membrane thickness and a reduction in voltage spread between electrodes, which are evaluated in batches using a multichannel analyzer. Gamma-ray ionization of the pH electrodes introduces a predictable voltage drift that follows a log decay function on the day timescale; the voltage decay rate correlates with membrane thickness and can be modeled as a parallel diode–capacitor circuit. Batches of radiation-sterilized pH electrodes were tested in cell culture media and yielded mean pH values within 0.05 units relative to a commercial meter (ground truth) following a single-point calibration protocol. Quantitative uncertainty analysis attributes more than half of total error to variations caused by ionizing radiation, and yields novel insights into strategies for reducing uncertainty.

Variational improvement of the wave-function at the sacrifice of spin-symmetry is exploited within the antisymmetrized product of strongly orthogonal geminals (APSG) Ansatz. The role of orbital optimization is explored for the unrestricted APSG wave-function, with applying half-projection for partial spin purification, prior to variation. Dynamical correlation is incorporated by a symmetry-adapted formulation of perturbation theory, which corrects for spin along with the effect of perturbation. Splitting between the lowest singlet and triplet levels of cyclobutadiene is investigated along the automerization coordinate of the ground state.
Features of the Emotional Component of Essential Self-Regulation Associated with Women's Marital Satisfaction
Authors: Kocharian Igor , Kuznetsova Daria
Published: January 2025

The article is dedicated to the study of the emotional component of essential self-regulation, which is related to women's marital satisfaction. Contemporary research on various aspects of the emotional sphere of personality and their connection to marital satisfaction is analyzed. The emotional component of essential self-regulation is considered one of the psychological regulators of the tendency towards self-actualization. Marriage is one of the directions of self-actualization, in which the tendency towards self-actualization is also realized. Therefore, we hypothesized that emotional factors that hinder the tendency towards self-actualization are associated with decreased marital satisfaction. The study involved 121 women aged 25-40. The author's methodology, QDES (Questionnaire for the Diagnosis of Essential Self-Regulation), was used. The research is based on the concept of Essential Self-Regulation - a system of emotional, behavioral, and communicative mechanisms of mental self-regulation that ensures the realization of the tendency towards self-actualization. The study confirmed the hypothesis of a reverse relationship between the emotional component of essential self-regulation and marital satisfaction. It was found that among the four ways of emotional response, namely: effectiveness, ambivalence, optimum, and apathy, it is the latter - apathy - that has a significant inverse correlation with women's marital satisfaction. A single-factor linear regression analysis between the variables of apathy and marital satisfaction showed mutual influence, allowing us to speak of a vicious circle, where if a woman tends to respond with low emotional tone - apathetically, she will also be inclined to perceive the marriage without enthusiasm, and vice versa, when a woman perceives her marriage as unsatisfactory, it predisposes to apathy.

The potential for hiking sports tourism in Lake Ciharus Kamojang is not potential to do, because not all tourist attractions in Kamojang can be visited like Lake Ciharus. Because this ciharus lake is a nature conservation protected forest area and is included in the category of nature reserve areas which have characteristics in the form of diversity and unity of types of living things, in the form of animals, plants, and their ecosystems. Because the government prefers to make it conservation to maintain and protect the high biodiversity in Lake Charles. Conservation areas, indeed, have great potential for the economy, but it must be underlined that the Lake Ciharus conservation area is not only an economic interest to be raised but there must be ecological value. However, for the time being, Lake Ciharus is still under review by BKSDA. The research method used is a qualitative method with a descriptive research design in the form of interviews, observation and documentation.
