Authors: Shroff Kavin Nishith , Shroff Uma Kavin , Gajiwala Uday Ranchhoddas
Published: December 2024

Objectives:

Retinopathy of prematurity (ROP) is a significant cause of preventable blindness among prematurely born babies. Advances in neonatal care support low-birth-weight babies and premature infants. These infants are more at risk of developing ROP. However, ROP is a preventable and treatable condition if newborns are screened in time. The study aims to identify the prevalence of ROP and assess the factors associated with ROP among newly born children in rural areas of South Gujarat.

Materials and Methods:

This was a hospital-based prospective study for 1 year and 5 months, that is, 2022, September to 2024, February 2024. All the preterm babies falling within inclusion criteria that is, babies born ≤34 weeks and or those with ≤2 kg and/or babies with a history of oxygen support, were included in the study. Bivariate statistics, Chi-square test, and logistic regression models were applied using the STATA version 14 software.

Results:

The study found that 4.8% of newborns had ROP. Extremely preterm adjusted odds ratio (AOR: 11.2, 95% confidence interval [CI]: 3.0–41.5) and very-low-birth-weight (AOR: 4.6; 95% CI: 1.7–12.5) infants exhibiting the highest risk. Furthermore, extremely low-birth-weight infants (AOR: 9.4; 95% CI: 2.8–31.8) and very-low-birth-weight infants (AOR: 7; 95% CI: 2.8–17.5) have a substantially higher likelihood of developing ROP than low-birth-weight infants. Surat district has having higher risk of developing ROP from south Gujarat.

Conclusion:

A low prevalence rate may be associated with low oxygen usage in rural areas, which needs further studies to confirm the association. These findings underscore the importance of targeted interventions and improved access to prenatal and neonatal care to mitigate the burden of ROP-related complications.

Authors: Buunk Abraham P. , Buunk-Werkhoven Yvonne A.B.
Published: December 2024

Aim: The aim was to examine how sense of defeat and social status are related to perceived oral health, tooth brushing, and oral health-related quality of life among Dutch male forensic psychiatric patients.Methods: The sample consisted of 40 hospitalized forensic psychiatric patients participated. The questionnaire included five questions about moments of tooth brushing, scales for sense of defeat and subjective social status, a scale from 1 to 10 for perceived oral health and a Dutch version of the Oral Health Impact Profile-14 (OHIP-14).Results: The results showed that on the basis of a factor analysis of the OHIP-14, three meaningful scales could be constructed, i.e., functional limitations, social discomfort, and psychological inhibitions. The major results revealed that sense of defeat correlated negatively with tooth brushing after breakfast and before going to sleep, positively with social discomfort because of one’s teeth, mouth, or dentures, not with functional limitations, and negatively with self-perceived oral health. Social status correlated positively with tooth brushing before going to sleep, with psychological inhibitions, but not with social discomfort, and neither with functional limitations.Conclusions and implications: The major conclusion is that sense of defeat and social status have theoretically meaningful relations with oral self-care and oral health. Oral health professionals working with male forensic psychiatric patients should be sensitive to the sense of defeat these patients may experience, and to the fact that this may be associated with problems with their oral health and with a lack of oral self-care.
Using the method of inverse growth calculations to determine the age composition of catches for certain species of marine commercial fish
Authors: Zolotov A. O.
Published: December 2024

New method for constructing size-and-age keys is proposed and tested on the data on size composition of yellowfin sole in commercial catches in the Patience Bay in 1950–2024, with the age of fish determined using the inverse growth calculations techniques. The method makes it possible to get a correct size-and-age key sufficient for estimating the age composition in catch on results of mass measurements when collection of age-recording samples is not available, and at the same time allows to neutralize an effect of fishing gear selectivity. The method was practically used in cases of pacific cod in the South Kuril fishing area and in the Japan Sea, yellowfin sole in Sakhalin waters, rock sole of genus Lepidopsetta in waters at the Kuril Islands and in the western Bering Sea, and pacific herring in the South Kuril area. The method may be useful for solving practical tasks of calculation the age composition in catches and subsequent assessments of stock and allowable catch volume for marine fish species.

Published: December 2024

Based on satellite images and standard sections obtained in 2000–2024, spatial structure of the Primorye Current as a band of cold waters along the coast of Primorye is considered. The archive of sea surface temperature reconstructed from the measurements of AVHRR radiometer (NOAA satellites) and MODIS spectroradiometer (AQUA, TERRA satellites) is used. The data were received and processed at the Center for collective use of regional satellite monitoring on environments in the Far-Eastern branch of Russian Ac. Sci. The main features of the Primorye Current structure are determined that allows to conclude that this cold-water area in the surface layer from the Tatar Strait to Peter the Great Bay is formed by a complex of coastal-shelf processes, including upwelling, vertical mixing, and desalination by terrestrial runoff. This cold, low-saline water mass spreads beyond the formation areas in general southwestward direction, along the coast, either as a continuous flow or as a chain of mesoscale eddies, spots, stripes, jets, etc., sometimes interrupted. The main provisions of this concept correspond with ideas established even before the satellite oceanography development, but some details concerning nature of the cold water of Primorye Current, its spreading along the coast of Primorye and interaction with surrounding waters were previously unknown.

Published: December 2024

Results of a quantitative diving survey of macrobenthos in the Avachinsky Bay at southeastern Kamchatka in October 2021 are presented. The survey was conducted in a year after the harmful algal bloom (HAB) with mass death of marine organisms in certain areas of the coastal zone. The depth range of 4–14 m was surveyed. In total, 92 species of macrobenthos were identified, the average biomass of macrobenthos was assessed in 2768.7 ± 2115.4 g/m2, and the average abundance — in 2449.9 ± 1502.1 ind./m2. The species structure of macrobenthos was similar to the results of survey conducted by Kamchatka researchers in the spring of 2021. Significant reduction in the number of species and biomass was detected then for sponges, anemones, gastropods, echinoderms and ascidia and confirmed again by our data. In October 2021, the portion of these taxonomic groups in the total biomass of macrobenthos on solid soils did not exceed 1–2 % that is evident consequence of significant changes in structure of the bottom community caused by mass death of benthic organisms during HAB in the fall of 2020. A year after the HAB, bivalves and polychaetes, as well as red and brown algae occupied the dominant positions in the community in terms of the species number and abundance, whereas pacific mussel Mytilus trossulus dominated by biomass (this species was dominant before the natural disaster and preserved this position) and subdominants were Hedophyllum bongardianum, Thalassiophyllum clathrus (Ochrophyta), Schisobranchia insignis (Polychaeta) and Ptilota asplenioides (Rhodophyta). Increasing in abundance of Amphipoda and Decapoda crustaceans was noted in 2021 relative to 2020.

Published: December 2024

An approach for obtaining high-level ab initio potential surfaces is described. The approach takes advantage of machine learning strategies in a two-step process. In the first, the molecular-orbital based machine learning (MOB-ML) model uses Gaussian process regression to learn the correlation energy at the CCSD(T) level using the molecular orbitals obtained from Hartree-Fock calculations. In this work, the MOB-ML approach is expanded to use orbitals obtained using a smaller basis set, aug-cc-pVDZ, as features for learning the correlation energies at the complete basis set (CBS) limit. This approach is combined with the development of a neural-network potential, where the sampled geometries and energies that provide the training data for the potential are obtained using a diffusion Monte Carlo (DMC) calculation, which was run using the MOB-ML model. Protocols are developed to make full use of the structures that are obtained from the DMC calculation in the training process. These approaches are used to develop potentials for OH-(H2O) and H3O+(H2O), which are used for subsequent DMC calculations. The results of these calculations are compared to those performed using previously reported potentials. Overall, the results of the two sets of DMC calculations are in good agreement for these very floppy molecules. Potentials are also developed for OH-(H2O)2 and OH-(H2O)3, for which there are not available potential surfaces. The results of DMC calculations for these ions are compared to those for the correspondingOH-(H2O)2 and OH-(H2O)3 ions. It is found that the level of delocalization of the shared proton is similar for a hydroxide or hydronium ion bound to the same number of water molecules. This finding is consistent with the experimental observation that these sets of ions have similar spectra.

Published: December 2024

Aqueous zinc ion batteries (ZIBs) are attracting increasing attention due to their low cost, earth abundance and safety. So far, they have been regarded as a promising battery system for large scale grid applications, and here we demonstrate prospects of their use to power portable devices. We have fabricated fully 3D printed and rechargeable ZIB with interdigitated geometry capable to power a commercial sensor for days. A full battery was assembled using aqueous and scalable formulations with a printed anode based on zinc powder and carbon black, a printed colloidal electrolyte and a printed MnO2 cathode. The anode withstands more than 500h of galvanostatic plating/stripping with a low overpotential of ~32.2 mV and the ZIB displays a capacity of ~1.3 mAh/cm² and a capacity retention of ~66% after 100 cycles. Finally, we show how this battery can power a Bluetooth proximity sensor for more than 3 days of continuous operation

Published: December 2024

Metal-Organic Frameworks (MOFs), renowned for their structural diversity and design flexibility, have demonstrated considerable potential in catalysis. However, the traditional trial-and-error approach is inefficient for optimizing catalytic performance in synthetic space. In this work, we propose MOFsyn Agent, a framework leveraging Large Language Models (LLMs) to guide the efficient synthesis and performance optimization of MOFs. MOFsyn Agent is an integrated system comprising two core components: data automatic analyzer and material mechanism analyzer. The system can be driven to perform data analysis operations such as task disassembly, code writing and execution by simple natural language commands only. Furthermore, the incorporation of the Retrieval-Augmented Generation (RAG) technology enables MOFsyn Agent to access external knowledge bases in real time, significantly enhancing its domain applicability in MOFs synthesis. Taking Ni@UiO-66(Ce) as an illustrative example, MOFsyn Agent conducted a comprehensive analysis of the relationships between synthetic conditions, structural characteristics, and catalytic performance. Through machine learning (ML), key features such as nickel content and metallic nickel were identified. Notably, MOFsyn Agent not only realizes the numerical prediction based on ML, but also optimizes the synthesis scheme from the textual level, and creatively proposes a step-by-step reduction strategy, which replaces the traditional one-pot direct reduction method. Experimental results demonstrated that the optimized Ni@UiO-66(Ce) can achieve saturated hydrogenation of dicyclopentadiene under more mild conditions (80 °C, 2 MPa) in only 1 h, validating the accuracy and reliability of the proposed method. This research provides an efficient tool for material intelligent synthesis to researchers without a programming background, accelerating the development process of new materials.
Relationship between smell, carbon number, and molecular structure of acetate esters
Authors: Inoue Shoya
Published: December 2024

Acetate esters, a group of substances found in natural fragrances and perfumes, are formed by the dehydration-condensation of acetic acid and alcohols and are known to have a variety of good smells. However, the regularity with which these smells change depending on the combination with the raw alcohol is not well understood yet. In order to investigate this, 13 alcohols with carbon numbers between 2 and 8 and phenol were used to synthesize and classify the smells, and the relationship between the smell of acetate esters, carbon number and molecular structure was compared. The results showed that the smell of acetate esters changes with changes in carbon number and with changes in molecular structure. These findings are discussed with respect to molecular polarization and human olfaction mechanisms.

Published: December 2024

Cycloaurenones and dysiherbols are naturally occurring sesquiterpene quinones/quinols that share a 6/6/5/6 tetracyclic carbon skeleton with either a cis- or trans-decalin system containing four contiguous stereocenters, including three contiguous all-carbon quaternary stereocenters. No total syntheses of cycloaurenones have been reported. Herein, we report the first divergent protecting-group-free syntheses of cycloaurenones and dysiherbols based on desymmetrization reactions of a chiral cyclohexadienone intermediate: namely, a Giese–Baran-type intramolecular cyclization and a new copper-catalyzed enantioselective conjugate addition. Moreover, we began our syntheses by installing the two 1,4-nonadjacent stereocenters via an unprecedented desymmetric enantioselective hydrogenation of a bis-α,β-unsaturated Weinreb amide intermediate (>99:1 d.r. and 99% e.e.).

Published: December 2024

It is well known that monoamine oxidase (MAO) plays a pivotal role in neurodegeneration and the inhibition of this enzyme can manifest anti-depressant properties as well as have a positive impact in Alzheimer’s and Parkinson’s diseases. Specifically, the MAO enzyme catalyzes the oxidative deamination of a variety of monoamines. This reaction leads to the formation of aldehydes, together with H2O2 and ammonia. Hydrogen peroxide can generate additional reactive oxygen species (ROS), this way leading to neurotoxicity. When MAO is activated, it induces the amyloid-beta (Aβ) deposition via abnormal cleavage of the amyloid precursor protein (APP) and contributes to the generation of neurofibrillary tangles and cognitive impairment due to neuronal loss. MAO has two isoforms: MAO-A and MAO-B. The main hMAO-B inhibitors used for the treatment of Alzheimer’s and Parkinson’s diseases, encompass a terminal triple bond in their structure, which provides their potency. Recently, a new class of inhibitors has emerged, bearing the carbon-carbon triple bond not necessarily at the end of the chain. In this review, the structure and physiological function of the MAO enzymes is discussed, as well as their mechanism of inhibition via terminal propargylamines. Moreover, it is highlighted the current development and discovery of potential hMAO-B inhibitors from propargylamine scaffolds and docking studies are performed to four of them by our group, in order to assess their binding energy with the enzyme. Finally, molecules which do not contain a propargylamine moiety in their structure were studied and compared against a known hMAO-B inhibitor, deprenyl. From the superimposition results of these molecules with deprenyl, as well as the interactions of the molecules with the amino acids of the active site of hMAO-B, it appears that these compounds have several similarities with deprenyl, opening new paths for the creation of novel molecules against Alzheimer’s disease.

The frenum is a fold of mucous membrane connecting the lips and cheeks to the gingiva periosteum and alveolar mucosa. It often contains muscle fibers. The maxillary labial frenum mandibular labial frenum and lingual frenum are the three most often seen frenum that are typically present in the oral cavity. Their main function is to stabilize the tongue upper lip and lower lip. The mucogingival junction and alveolar mucosa involved in the frenum are said to be structurally identical to those in any other area. The limited information on frenum per se and its clinical implications has not been adequately dealt with in the literature. Hence an attempt was made to present them in this review.

Published: December 2024

Large multiprotein machines are central to many biological processes. However, stoichiometric determination of protein complex subunits in their native states presents a significant challenge. This study addresses the limitations of current tools in accuracy and precision by introducing concatemer-assisted stoichiometry analysis (CASA). CASA leverages stable isotope-labeled concatemers and liquid chromatography–parallel reaction monitoring–mass spectrometry (LC-PRM-MS) to achieve robust quantification of proteins with sub-femtomole sensitivity. As a proof of concept, CASA was applied to study budding yeast kinetochores. Stoichiometries were determined for ex vivo reconstituted kinetochore components, including the canonical H3 nucleosomes, centromeric (Cse4CENP-A) nucleosomes, centromere proximal factors (Cbf1 and CBF3 complex), inner kinetochore proteins (Mif2CENP-C, Ctf19CCANcomplex), and outer kinetochore proteins (KMN network). Absolute quantification by CASA revealed Cse4CENP-Aas a cell cycle–controlled limiting factor for kinetochore assembly. These findings demonstrate that CASA is applicable for stoichiometry analysis of multiprotein assemblies.

Published: December 2024

Genetic algorithm (GA) is well-known algorithm to find a feasible path planning which can be defined as global optimum problem. The drawback of GA is the high computation due to random process on each operator.  In this research, the new initial population integrating with new crossover operator strategy was proposed. The parameter is the length of distance travelled of the robot. Before employing the crossover operator, generating a c-obstacle have been done. The c-obstacle is used  as a filter to reduce unnecessary nodes to decrease time computation. After that, the initial population has been determined. The initial population is divided into two parents which parent’s chromosome contains an initial and goal position. The second parents are fulfilled with nodes from each obstacle. The genes of chromosome will add with c-obstacle nodes. Crossover operator is applied after filtering and c-obstacle of possible hopping is determined. Filtering method is used to remove unnecessary nodes that are part of c-obstacle. Fitness function considers the distance from  the last to next position. Optimum value is the shortest distance of path planning which avoids the obstacle in front.  The aim of the proposed method is to reduce the random population and random operating in GA. By using a similar data set of previous researches, the modified GA can reduce the total of generation and yield an adaptive generation number. This means that the modified GA converges faster than the other GA methods.

Background. Bronchial asthma (BA) in children is a chronic inflammatory disease of the bronchopulmonary system and, with all the diversity of polyetiological potential and clinical manifestations, develops as an immunopathological process. New approaches to the therapy of bronchial asthma in children are the most urgent problem. A promising direction is the use of dosage forms of phosphodiethylcholine liposomes with an expanded spectrum of their pharmacological focus using the drug «Ektericide» with a wide spectrum of antibacterial, immunomodulatory and antioxidant activity as a dispersion medium.

Purpose is to determine the effect of the liposomal form of lipin in physiological and bactericidal solutions on the state of the immune system in children with bronchial asthma.

Materials and Methods. 126 children with bronchial asthma between the ages of 5 and 14 in remission were examined. The influence of liposomal forms of Lipin on the state of the immune system in children with bronchial asthma was evaluated. In the work, immunological methods of research of the humoral and cellular links of immunity were used. The obtained results were processed by assessing the probability of differences in mean values in groups (p) using the Student’s test (t). Differences were considered statistically significant at p<0.05.

Results. The use of liposomal forms in an extericidal solution by inhalation through an ultrasonic inhaler in a complex scheme of BA therapy leads to the normalization of the humoral and cellular links of immunity, reduces the inflammatory process and IgE at all degrees of severity of the course of bronchial asthma, normalizes markers of CD8 T-suppressors/killers, significantly reduces the number of mononuclear cells, which carry one of the markers of apoptosis – СD95 – on their membrane.

Conclusions. The use of the liposomal form of lipin in an ectericidal solution leads to the normalization of immunological indicators of immunity and allows to reduce the use of inhaled and oral glucocorticosteroids in children with bronchial asthma.

Published: December 2024

This study scrutinizes the authorial presence in English and Indonesian research articles written by Indonesian authors. The study aims to identify the frequency of first-person pronouns used as a form of authorial presence across research articles. Furthermore, the study also intends to examine the discourse functions of these first-person pronouns in academic writing. A corpus of 168,122 words was analyzed by utilizing corpus linguistics methodology. The findings show that there is a difference in the use of first-person pronouns between the English and Indonesian sub-corpora with the most frequent usage of first-person pronouns found in English research articles. In addition, the study investigated the clusivity and the discourse functions of first-person pronouns within the research articles in both English and Indonesian. The results indicate that Indonesian authors tend to adopt the Western academic style in using first-person pronouns as authorial presence despite the conservative style used in their native language. This reflects the different norms of academic discourse across languages.

Published: December 2024

Irwan Jamal, the founder of the Pictorial Theatre and the Casanova Theatre, is an artist who has studied several art disciplines at once, including theatre, visual arts, literature, and music. Genetic influences from his father’s family, who are skilled in drawing, as well as his education and experience in theatre, have resulted in a form of theatre that is rich in visual expression. This is based on Sigmund Freud’s theory of primary creativity which grows and becomes the foundation of one’s creativity. This article will also discuss and analysed the influence of the visual arts on Irwan Jamal’s vision of theatrical creations in terms of the several works he has directed, both theatrical productions as well as films and music videos. Irwan Jamal’s artistic vision and expression, which was later categorized as a form of “expressionist theatre” was very strongly influenced by the fine arts that Irwan Jamal also studied. The method used to analyse Irwan Jamal’s works (theatre and music videos) will also use the formal structure criticism method, which is usually used for the analysis of a painting. The presentation of critical works uses the method introduced by Edward S Feldman.

Published: December 2024

Artykuł przybliża najważniejsze zagadnienia poruszane w ostatniej książce Salomé Voegelin zatytułowanej Uncurating sound. Knowledge with Voice and Hands, w której autorka rozwija filozofię dźwięku zaproponowaną w Listening to Noise and Silence oraz kontynuowaną w kolejnych monograficznych publikacjach. Autorka artykułu przybliża zagadnienia polityczności słuchania i możliwych światów dźwiękowych z tekstów Voegelin. W jej ujęciu omawiana książka kładzie nacisk na potrzebę przekształcenia instytucji sztuki w przestrzeń opiekuńczą, krytycznie analizuje współczesną sztukę, argumentując za koniecznością wyjścia poza instytucjonalne ramy i postuluje restrukturyzację zarówno dźwiękowej wiedzy, jak i instytucji sztuki, szczególnie w obliczu nowych wyzwań, takich jak pandemia i postnormalność.

The study aimed to explore changes in serum creatinine, iron, and blood metabolites in different parity statuses in traditionally managed Saanen Etawah crossbred goats. Mature lactating goats (n = 130) were divided into primiparous (n = 45) and multiparous groups (n = 85) (body condition score 3, early-middle stage of lactation). Blood samples were collected from the jugular vein and centrifuged to collect plasma; blood metabolites were measured using UV Vis methods. The result showed creatinine concentrations in multiparous goats were significantly (P < 0.05) higher (0.87 ± 0.21 mg/dl) than in the primiparous group (0.79 ± 0.15 mg/dl). Meanwhile, the albumin concentration in primiparous goats (3.99 ± 0.20 mg/dl) was significantly higher than in multiparous goats (3.82 ± 0.16 mg/dl); also the total cholesterol level of primiparous goats (122.28 ± 29.20 mg/dl) was significantly higher than in multiparous goats (107.37 ± 24.40 mg/dl). The urea-creatinine ratio was higher in primiparous goats (27.07 ± 11.90) than in multiparous goats (22.37 ± 8.12). It was concluded that distinct blood metabolites between primiparous and multiparous goats were due to different physiological needs which led to different mobilization of stored nutrients inside the body. Different feeding strategies were suggested for each parity group following their nutritional needs, such as a high-protein diet to optimize primiparous body development, and a high-energy diet to enhance multiparous milk production before and after giving birth. Further research is needed to understand the exact optimal ratio of feed energy and protein.
In vitro biomechanical comparison of three parallel cortical screws versus three crossed cortical screws for arthrodesis of the equine proximal interphalangeal joint

Published: December 2024

The maintenance of rigid stability and compression of the pastern joint, similar to fracture repair, is required for successful pastern arthrodesis. Many techniques and variations on each technique have been studied biomechanically in vitro and confirm that some fixations provide more stability than others. In our study, the strength of a modified method of arthrodesis of the proximal interphalangeal joint using one axial and two abaxial screws was compared with a standard parallel arthrodesis technique by mechanically loading arthrodesis constructs on paired cadaveric limbs. These cadaveric limbs underwent mechanical destruction in a bend in a palmar (plantar)-to-dorsal direction. The assessment of the strength of arthrodesis constructs was based on the evaluation of the maximum loading force and the comparison of radiographs performed before and after loading. The measurements show that in 6 cases out of 7, the strength of the modified (crossed) arthrodesis method was higher compared to the parallel method.
Immunohistochemistry of poorly differentiated squamous cell carcinoma in a Slovak Warmblood gelding – a case report
Authors: Levkut Martin , Šufliarska Zuzana
Published: December 2024

This case report describes the immunohistochemical examination of poorly differentiated squamous cell carcinoma (SCC) in a sixteen-year-old Slovak Warmblood gelding. Clinical examination detected a dull, painless percussion in frontal and maxillary sinuses. The left arch of the mandible had an irregular surface with a painful tap. The submandibular lymph nodes were bilaterally asymmetric with left sided hypertrophy, smooth to palpation, hard and painless. The tumorous mass was overgrown through the laryngeal mucosa, not observed in the oral cavity. The patient was in a poor clinical condition and was euthanized six months after the first clinical signs were observed. Histological examination of the samples taken from the tumorous mass showed the presence of proliferated cells of epithelial origin. The histological finding of the mandible showed focal osteolysis with multinuclear cells, which were bordered by mesenchymal tissue and a moderately dense collagen. Immunohistochemically, tumorous cells were positive for p63 and cytokeratin AE1/AE3. Protein p63 confirmed the metastatic spread of the tumour and was demonstrated to be a suitable marker for poorly differentiated SCC.
