This study aimed to explore the relationship between body image, eating behaviour, and physical activity among students at the National Defence University of Malaysia (UPNM). A total of 114 students, aged between 19 to 31 years old, were requited from the National Defence University of Malaysia (UPNM). Data were collected using an online self-report questionnaire which consists of four sections; Sociodemographic Form, Body Image Avoidance Questionnaire (BIAQ), Eating Attitude Test (EAT-26), and the International Physical Activity Questionnaire (IPAQ). Almost half of the respondents have normal BMI, whereas 20.2% were underweight and 23.7% were overweight and obese. Mean body image avoidance scores for civilian students, Reserve Officer Training Unit (ROTU), and cadets were 38.88±12.39, 42.71±6.34, and 44.00±16.05, respectively. Furthermore, high physical activity level was seen the most among civilian students (72.3%) compared to (57.1%) and cadets (41.7%). Significant associations were found between body image and eating behaviour (p<0.001). No association was observed between body image with physical activity (p>0.05) and eating behaviour with physical activity (p>0.05). To conclude, the respondents with a risk of the eating disorder tend to have higher body image avoidance, and the physical activity level did not seem to be concerning body image and eating behaviour in this study.

Published: September 2024

This research aimed to assess knowledge, attitude, and practices regarding traditional herbs and spices consumption among Malaysian adults aged 18 to 60 years. A- 5-parts close-ended questionnaire was partially adapted and modified from articles and validated by 11 experts. Data collection was performed by using an online questionnaire (n=281). Most participants are female (75.4%) and Malay (85.1%), followed by Chinese (10.0%), Indian (2.1%), and other ethnicities (2.8%) such as Sabah natives, Iban, Dusun, and Javanese. Most respondents consumed traditional herbs and spices. Centella asiatica ('pegaga'), ginseng, Labisia pumila ('kacip fatimah'), and longjack ('tongkat ali') were the most consumed herbs whereas lemongrass, garlic, ginger, turmeric, and star anise were the most consumed spices. The study found good knowledge, fair attitude, and poor practice regarding traditional herbs and spices consumption. Knowledge was significantly associated with ethnicity, while consumption status was associated with attitude and practice levels. A moderate and positive correlation was observed between attitudes and practices. Enhancing public knowledge and promoting positive attitudes towards these traditional ingredients is essential for preserving cultural heritage and incorporating them into modern diets.

Published: September 2024

The main purposes of this study are to assess the consumers' acceptance of the sensory attributes of energy powder made from guarana as caffeine and to determine the nutritional values of energy powder made from guarana as a substitute for coffee. The method used to conduct this research is measuring proximate analysis of ash, moisture, protein, fat, and crude fibre to identify energy powder's nutrient content. Besides, it discovers the acceptance of energy drinks towards potential consumers by undergoing a 7-point hedonic sensory evaluation test of 25 semi-panels. The outcomes gained from this research are low protein, low fat, and high minerals due to the high ash content, presenting that it is acceptable for energy drinks since it usually focuses on total energy and sugar for energy boost. The panellist's acceptance is concentrated in viscosity and colour, which might concern Agarbomb’s improvement in aroma, taste, and overall acceptability.

Published: September 2024

This study aims to develop and validate a module on managing diet, lactation, and emotion for postnatal mothers. This cross-sectional study involves three phases: needs assessment, module development, and module validation. About 37 mothers aged 18 to 49 years old with infants less than 6 months were recruited, and information on postnatal care practices, lactation knowledge, and emotion were obtained for module development. The guidelines from the Ministry of Health Malaysia and literature served as the foundation for the module that was developed following the requirements assessment utilizing the Health Belief Model (HBM). Content and face validity of the module is carried out to validate the developed module. The validation form used was adapted from Silveira de Castro (2007) which consists of seven criteria, two criteria related to content validity and another five criteria related to face validity. The content validity was assessed using a Content Validity Index (CVI). CVI was calculated using two different formulas: I-CVI and S-CVI. Meanwhile, a level of agreement was used in the data for the module's face. From the need assessment, most mothers with restricted seafood and nuts intake struggled to breastfeed and about 21.6% of them experienced postpartum depression. The developed module has been validated with both mean I-CVI and S-CVI more than 0.78 and 0.80, respectively. Meanwhile, five face validation components achieved 75% agreement, confirming the validity. In conclusion, the developed module named The LEDies has good validity and can serve as teaching material for postnatal mothers caring for themselves and their infants during the postpartum period.

Published: September 2024

Thermal burns of the face and neck remain one of the most common accidental injuries in young adults. This leads to various sequelae including scar, contracture, and alopecia. The goal of management is to achieve a complete range of motion of neck movements and restore esthetic appearance. Many reconstructive options are available in the form of split skin grafts, tissue expanders, loco-regional flaps, free flaps, and hair transplantation. Here, we report a case of severe postburn neck contracture and beard alopecia as sequelae of accidental thermal burns sustained by him 2 years back. The patient was successfully managed with contracture release followed by an expanded neck flap for coverage of the resultant defect. We also present the outcome and follow-up of the patient, after receiving follicular unit extraction from the scalp and contra-lateral un-burnt beard region for treatment of patchy postburn alopecia over the burnt beard area of the face. The quality of facial scarred skin has improved dramatically following the hair transplant which was proven by the punch biopsies obtained from the treated skin.

Authors: Kulkarni Shreenidhi , Kim Do-Hyoung , Ha Ji Soo , Kim Chang-Wook , Sakhrekar Rajendra , Han Hee Don
Published: September 2024

Background:

Herniated nucleus pulposus (HNP), without causing significant neurological deficit, is a more frequently occurring disease of the spine affecting the activities of daily living with chronic back pain and sometimes progressing to produce significant functional deficit. Trans-sacral epiduroscopic laser decompression (SELD) is being increasingly used as a treatment modality for these conditions and has been shown to give effective results. We present the clinical outcomes of the patients undergoing SELD in our institute for HNP.

Methods:

A retrospective study of 411 patients who underwent SELD for lumbar disc herniation was done, analyzing the clinical outcomes by measuring visual analog scale (VAS) scores for leg pain and back pain, Oswestry Disability Index (ODI) score, and Short form health survey (SF -36) scores and followed up for 6 months.

Results:

A total of 195 males and 216 females underwent SELD, with a mean age of 33.2 ± 0.9 years and a mean follow-up period of 7 ± 1.6 months. VAS scores for back pain and leg pain improved significantly from 6.9 ± 0.5 and 6.6 ± 0.6 preoperatively to 1.1 ± 0.5 (P > 0.05) and 0.4 ± 0.5 (P > 0.05) at 6 months. ODI score decreased from 28.2 ± 1.7 to 9.4 ± 1.7 at 6 months from the intervention (P < 0.05). SF-36 showed significant improvement in overall categories through 6 months of follow-up. Twenty-four patients had dural punctures, and four patients needed blood patches but recovered without any complications. One patient had aggravation of the disc herniation post-procedure, and was managed by endoscopic discectomy.

Conclusion:

SELD is a safe, accurate, and effective procedure in treating symptomatic lumbar disc herniation with excellent clinical outcomes and effective pain relief with minimal damage to paraspinal muscles with an easier learning curve, reproducible results, and high safety index.

Published: September 2024

Автоматизация управления при глиссировании самолета-амфибии по водной поверхности в настоящее время ограничивается средствами повышения устойчивости (демпферами). Предложен способ улучшения путевой управляемости самолета-амфибии при глиссировании по водной поверхности, включая парирование отказа критического двигателя. Способ основан на использовании полуавтоматического управления аэродинамическими поверхностями управления и включает в себя автоматическое создание крена по принципу, аналогичному тому, который применяется для сохранения путевой управляемости в случае отказа критического двигателя в полете (в воздухе). Разработан и исследован в экспериментах на пилотажном стенде алгоритм устройства, реализующего предложенный способ.

Automation of the control in the amphibious aircraft gliding over the water surface is currently limited to the means of stability increasing (dampers). A method for the directional controllability augmentation of an amphibious aircraft during glidi ng over the water surface, including overcome of the critical engine failure, is proposed and investigated at the flight simulator. The method is based on the use of semi-automatic control of aerodynamic control surfaces and includes the automatic creation of a roll in a manner analogous to that used to preserve the directional controllability in the event of a critical engine failure in fl ight (in the air).

Разработан метод априорного анализа тепловой нагрузки электронных компонентов, вызванных тепловыми процессами, протекающими в печатных узлах электронных блоков космических аппаратов. Метод позволяет разработчику проводить исследования тепловых режимов на этапах эскизного и технического проектирования и получать значения тепловых нагрузок на электронных компонентах печатных узлов до изготовления опытного образца. В случае перегрузки конкретного электронного компонента (или компонентов) разработчик применяет один из вариантов охлаждения и проводит проверочное моделирование. При исследовании тепловых режимов введены коэффициенты нагрузок, которые устанавливаются с учетом запасов на случайные разбросы параметров электронных компонентов и материалов несущих конструкций. Применение метода проиллюстрировано на примере обеспечения требуемого теплового режима электронного вычислительного блока, устанавливаемого на космическом аппарате.

The authors describe the developed method of a priori analysis of the thermal loads of electronic components caused by thermal processes occurring in printed circuit assemblies of the electronic units of spacecraft. The method allows the developer to conduct studies of the thermal regimes at the stages of the preliminary and technical design and obtain the values of thermal loads on the electronic components of the printed circuit assemblies prior to the production of the prototype. In case of overloading of a specifi c electronic component (or components), the developer applies one of the cooling options and conducts the verifi cation simulation. In the study of thermal conditions, the authors introduce load factors, which are set taking into account the reserves for random variations of the parameters of electronic components and materials of bearing structures. The application of the method is illustrated by the example of providing the required thermal regime of an electronic computing unit installed on a satellite.

Жимолость Шамиссо – невысокий кустарник, распространённый в районах Дальнего Востока, для которых характерен глубокий снежный покров в зимнее время. На Сахалине он встречается преимущественно в двух резко различающихся типах местообитаний – в субальпийском поясе и в низинах, почти избегая пояса темнохвойных лесов. Вид, вероятно, возник в высокогорьях в одну из тёплых геологических эпох. Среди его особенностей – крайне низкая требовательность к почвам, высокая – к освещённости, а также задержка прорастания семян (лишённых периода покоя) при низких температурах. Описаны особенности роста и развития сеянцев в условиях интродукции на Сахалине в ботаническом саду. Проведено сравнение сезонного цикла в разных пунктах интродукции, описано развитие зачатков цветков.

Honeysuckle Chamisso is a low shrub, which is distributed in areas of the Far East, which characterized by deep snow cover in winter. On Sakhalin it is distributed mainly in two sharply different types of habitats - in the subalpine belt and in the lowlands, almost avoiding the altitudinal vegetation belt of dark-coniferous forest. The species probably originated in the alpine zone in one of the warm geological epochs. Among its features - extremely low requirements from the soils, high requirements from light, as well as delay the germination of seeds (devoid of seed dormancy) at low temperatures. Specific features of growth and development of seedlings in conditions of introduction on Sakhalin in the botanical garden are described. The seasonal cycle is compared in different points of introduction, the development of flower rudiments is described.

DISCOVERY, INVESTIGATION AND APPLICATION OF DYNAMIC NUCLEAR POLARIZATION EFFECTS. PARTICIPATION OF SOVIET PHYSICISTS (1953–2012)
Authors: Кессених А.В.
Published: September 2024

Взаимодействие ядерных спинов с внешним магнитным полем и решеткой устанавливает через процесс парамагнитной релаксации равновесное значение поляризации их магнитных моментов. В присутствии в образце неспаренных электронных спинов существует возможность при возбуждении (насыщении) квантовых переходов на частотах электронного парамагнитного резонанса (ЭПР), благодаря процессам электронно-ядерной релаксации или при прямой накачке населенностей ядерных магнитных подуровней добиться значительного (до трех порядков и более) возрастания поляризации (разности населенностей уровней) или динамической поляризации ядер (ДПЯ). Эффекты ДПЯ, открытые в 1953–1968 гг., различаются в зависимости от вида спектра ЭПР. ДПЯ облегчает применение экспериментальных методов исследования структуры химических соединений (ядерный магнитный резонанс или ЯМР), наблюдение за превращениями биологически активных субстанций в организме, исследования явлений, на которые влияет ориентация спина и спинового магнитного момента. Рассмотрена зависимость трех основных типов эффектов ДПЯ от спектра ЭПР и краткая хронология их открытия с участием советских ученых.

The interaction of nuclear spins with an external magnetic fi eld and a lattice establishes through the paramagnetic relaxation process the equilibrium value of the nuclear polarization . In the presence of unpaired electron spins in the sample, it is possible to achieve a signifi cant (up to three orders) increase in the polarization by the excitation of quantum transitions at electron paramagnetic resonance (EPR) frequencies, due to electron-nuclear relaxation processes or direct pumping of populations of nuclear magnetic levels, so called dynamic nuclear polarization (DNP). The various effects of the DNP, discovered in 1953–1968, differ depending on the type of EPR spectrum. The DNP facilitates the use of experimental methods for studying the structure of chemical compounds (nuclear magnetic resonance or NMR), monitoring the transformations of biologically active substances in the body, and studying other phenomena infl uenced by the orientation of the spin and the spin magnetic moment. The dependence of the three main types of DNP effects on the EPR spectrum and a brief chronology of their discovery with participation of Soviet scientists are considered.

Published: September 2024

В статье рассматриваются и анализируются сообщения Готфрида Мерцбахера о поселениях и жилищах горских татар второй половины XIX века. Материалом для данного исследования послужил двухтомный труд немецкого альпиниста «Из высокогорных районов Кавказа» [1], ставший результатом двух научных экспедиций Мерцбахера. Несмотря на то, что главной целью путешествия альпиниста было покорение высочайшей вершины Европы, горы Эльбрус, во время пребывания на Кавказе исследователь собрал ценные сведения о народах кавказского высокогорья. Цель данного исследования неразрывно связана с необходимостью пополнения источниковедческой базы этнографии балкарцев неизвестными ранее отечественным кавказоведам трудами европейских путешественников XIX века.

The article examines and analyzes reports of Gottfried Merzbacher about the settlements and dwellings of the mountain tatars of the second half of the XIX-th century. The material for this study was a two-volume work of a german climber «From the Highlands of the Caucasus» [1], which was the result of two scientific Merzbacher's expeditions. Despite the fact that the main purpose of the mountaineer's journey was to conquer the highest peak of Europe, mount Elbrus, during his stay in the Caucasus, the researcher collected valuable information about the peoples of the Caucasian highlands. The purpose of this study is inextricably linked with the need to replenish the sources of ethnography balkarians unknown earlier by the domestic caucasus studies of European travelers of the XIX century.

В работе описывается концепция разработки программно-аппаратного средства (ПАС), предназначенного для контроля параметров его вращательного движения. Для разработки ПАС используется опыт наземных, летных испытаний и эксплуатации летного и опытного образцов МКА “Аист”. Данный опыт позволяет делать выводы о целесообразности тех или иных решений и подходов, а также разрабатывать алгоритмы более эффективной работы ПАС. Результаты работы могут быть использованы при проектировании МКА, не имеющих полноценной системы управления и эксплуатирующихся в неориентированном полете. Они частично внедрены и опробованы при испытаниях и эксплуатации МКА “Аист – 2Д”.

Published: September 2024

В статье рассматривается особый тип издания фольклора  — это высокохудожественная, отличающаяся первоклассной полиграфией книга, предназначенная для широкого круга читателей. Отмечается, что книги подобного рода, называвшиеся «роскошными», существовали и в XVIII, и в XIX вв., но в подавляющем большинстве они были не фольклорного содержания. Процесс становления такого типа издания фольклора показан на примере трех опытов: «Альбома русских народных сказок и былин», вышедшего в 1875 г. в издательстве Г.Д. Гоппе, экспериментов Е.Д. Поленовой второй половины 1880-х гг. и серии русских сказок из 6 книжек-тетрадей в оформлении И.Я. Билибина, напечатанных в Экспедиции заготовления государственных бумаг (1901–1903). В статье освещается история создания данных книг, характеризуются их особенности. Показывается, что новаторские принципы оформления фольклорного издания, разработанные Е.Д. Поленовой, не были воплощены в  качественный полиграфический продукт. Примерно 20 лет спустя соединение усилий И.Я. Билибина, нашедшего стиль оформления фольклорного произведения, воспринятый многими поколениями читателей как наиболее адекватный такого рода текстам, и Б.Б. Голицына, обеспечившего изданию уникальную полиграфическую базу, позволило сделать существенный шаг к закреплению за фольклорной сказкой статуса символа национальной культуры. В заключение подчеркивается, что художественные издания фольклора выполняют в культуре общества специфическую функцию, превращая народное творчество из наследия прошлого в эстетический феномен настоящего.

This article considers a special type of folklore publication — an artistic book, distinguished by first-class printing and intended for a wide range of readers. Books of this kind, labeled as “luxurious,” existed in the eighteenth and nineteenth centuries, but the vast majority of them were not editions of folklore. The development of artistic folklore publications is traced by examining three examples: the Album of Russian Folk Tales and Epics published in 1875 by the publishing house of G.D. Hoppe; the works of E.D. Polenova in the second half of the 1880s; and a series of Russian fairy tales in booklets designed by I. Ya. Bilibin and printed by the “Expedition Preparing Government Papers” (1901–1903). The article describes the creation of these books and characterizes their main features. Polenova developed innovative principles of design for folklore publications but they were not embodied in a high-quality printed product. About twenty years later, the combined efforts of I. Bilibin, who created a style for works of folklore that many generations of readers considered the most adequate for such texts, and B.B. Golitsyn, who produced the booklets with a unique printing facility, made a significant step toward securing the status of symbol of national culture for folklore tales. In conclusion, the author argues that the artistic publication of folklore performs a specific function in society and culture, turning folk art from the heritage of the past into an aesthetic phenomenon of the present.
Komi Fairy Tale Tradition and the Book
Authors: Коровина Н.С.
Published: September 2024

Материалом для наблюдений в данной статье стал сказочный сюжет СУС 1640 «Фома Беренников». Как показал текстологический анализ, источником для всех рассмотренных коми сказок стала книга, вне зависимости от того, как она повлияла на текст конкретного сказочника: непосредственно или опосредованно (уже будучи достоянием устной традиции). Коми сказки, рассмотренные нами, по-разному удалены от книжных источников. Одни из них довольно точно отражают содержание книги, в других источник подвергается существенной обработке, в них вносятся дополнения и изменения, включаются новые эпизоды и мотивы. Немаловажную роль в усвоении книги сыграло расширение круга грамотных людей, наличие двуязычия у коми. Вместе с тем рассмотрение коми регионального материала меняет представление о стабильности и незыблемости законов народной сказки. При современном процессе затухания сказочной фольклорной традиции произошли изменения в наиболее устойчивой ее составляющей — сюжетно-композиционном строении. Широкое варьирование коми сказочниками сюжетов, образов, их трансформация привели к «новеллизации» некоторой части коми сказок, превращению их в авантюрно-фантастические устные повести. Приведенные в данной статье факты еще раз подтверждают, что коми сказочный фонд нуждается в критической проверке, поэтому эдиционно-текстологические исследования приобретают в настоящее время в коми фольклористике значимость и актуальность и заслуживают самого пристального внимания.

This article considers a fairy tale plot recorded in the “Comparative Plot Index” under number 1640, “Foma Berennikov.” Textual analysis shows that the source for all of the Komi fairy tales with this plot was written, whether the written version influenced the text of a particular storyteller directly or had become part of the oral tradition earlier and reached the performers indirectly. The Komi tales the author reviews are removed from their written sources to different degrees. Some of them quite accurately reflect a written text, while others underwent adaptation; the latter exhibit various changes, such as the addition of new episodes and motifs. An important role in the assimilation of written texts was played by the expansion of literacy and the presence of bilingualism among the Komi. Examination of this regional Komi material alters our notion of the stability and inviolability of the laws of the folk tale. With the attenuation of the fairy tale tradition in the modern period, changes occurred in its most stable component — the plot-compositional structure. The wide variation of plots and images and their transformation by Komi storytellers led to the “novelization” of some Komi fairy tales and their adaptation into adventurous and fantastic oral stories. The material presented in this article once again confirms that the corpus of Komi fairy tales needs verification, and that, therefore, critical editing and textual study of Komi folklore are essential and deserve the closest attention.
Enhancing Urban Livability Place Making of Outdoor Spaces within Transit-Oriented Development (TOD)
Authors: Abednego Ivan Adiel , Ronaldo Christopher
Published: September 2024

Urbanization profoundly impacts urban spaces, often resulting in inadequate planning, integration, and sustainability. Enhancing urban livability can overcome these problems with Place Making of Outdoor Spaces within Transit-Oriented Development (TOD). This study integrates insights from two research perspectives: firstly, exploring sustainability in outdoor spaces broadly through behavior mapping, documentation, and semi-structured interviews; secondly, focusing specifically on Rajawali Station in Jakarta. Despite Jakarta’s TOD emphasis, gaps persist in implementing placemaking principles effectively. Employing qualitative methods, including behavior mapping and stakeholder interviews, this research assesses current usage patterns and proposes placemaking strategies for Rajawali Station. Based on the identification results, a mechanism for using outdoor space is needed to improve the quality of urban livability. Apart from that, based on the evaluation results, collaboration is needed in the use of outdoor space by users. The impact of this collaboration can produce design recommendations based on sustainable human orientation. These recommendations are crucial for guiding sustainable urban development efforts and fostering community-centric outdoor spaces within TODs.

Bi2SeO2 is a promising n-type semiconductor to pair with p-type BiCuSeO in a thermoelectric (TE) device. The TE figure of merit zT and, therefore, the device efficiency must be optimized by tuning the carrier concentration. However, electron concentrations in self-doped n-type Bi2SeO2 span several orders of magnitude, even in samples with same nominal compositions. Such unsystematic variations in the electron concentration has a thermodynamic origin related to the variations in native defect concentrations. In this study, we use first-principles calculations to show that the selenium vacancy, which is the source of n-type conductivity in Bi2SeO2, varies by 1-2 orders of magnitude depending on the thermodynamic conditions. We predict that the electron concentration can be enhanced by synthesizing under more Se-poor conditions and/or at higher solid-state reaction temperatures (T_SSR), which promote the formation of selenium vacancies without introducing extrinsic dopants. We validate our computational predictions through solid-state synthesis of Bi2SeO2. We observe more than two orders of magnitude increase in the electron concentration simply by adjusting the synthesis conditions. Additionally, we reveal the significant effect of grain boundary scattering on electron mobility in Bi2SeO2, which can also be controlled by adjusting T_SSR. By simultaneously optimizing the electron concentration and mobility, we achieve a zT of ~0.2 at 773 K for self-doped n-type Bi2SeO2. Our study highlights the need for careful control of thermodynamic growth conditions and demonstrates TE performance improvement by varying synthesis parameters according to thermodynamic guidelines.
Insights into Thermal Conductivity at the MOF-Polymer Interface
Authors: Vo Phuong , Haranczyk Maciej
Published: September 2024

Understanding the thermal conductivity in MOF-polymer composites is crucial for optimizing their performance in applications involving heat transfer. In this work, several UiO66-polymer composites (where polymer is either PEG, PVDF, PS, PIM-1, PP or PMMA) are examined using molecular simulations. Our contribution highlights the interface's impact on thermal conductivity, observing an overall increasing trend attributable to the synergistic effect of MOF enhancing polymer thermal conductivity. Flexible polymers like PEG and PVDF exhibit increased compatibility with the MOF, facilitating their integration with the MOF lattice. However, this integration leads to a moderated enhancement in thermal conductivity compared to polymers that remain separate from the MOF structure, such as PS or PP. This effect can be attributed to alterations in phonon transport pathways and shifts in interfacial interactions between the polymer and MOF. Specifically, the infiltration of the polymer like PEG and PVDF into the MOF disrupted the MOF’s ordered network, introducing defects or barriers that hindered phonon propagation. In contrast, non-polar and rigid polymers like PP, PMMA, PS, and PIM-1 exhibited greater improvements in thermal conductivity when combined with MOFs compared to the flexible polymers PVDF and PEG. Most notably, our analysis identifies a critical interface region within approximately 30-50 Å that profoundly influences thermal conductivity. \textcolor{blue}{The interface region, as indicated by the density profile and radius of gyration, is notably shorter but plays a pivotal role in modulating thermal properties}. The sensitivity of the system to these interface characteristics underscores the crucial role of this particular interface area in dictating thermal conductivity. Our findings emphasize the sensitivity of thermal conductivity in polymer matrices to interface characteristics and highlight the critical role of a specific interface region in modulating thermal properties.

Here, we report that a 9-fluorenylmethoxycarbonyl (Fmoc)-modified taurine (Fmoc-Tau) can act as a hydrogelator. The supramolecular hydrogels of Fmoc-Tau were constructed through the self-assembly to form self-assembled fibrous structures under physiologically relevant aqueous conditions. Fluorescence microscopy was employed to investigate the accumulation of basic fibroblast growth factors along the self-assembled fibrous structures.

Fast and accurate spectral prediction plays a crucial role in molecular design within fields such as pharmaceutical and materials science. Nevertheless, predicting molecular spectra typically requires quantum chemistry calculations, posing significant challenges for fast predictions and high-throughput screening. In this paper, we propose an equivariant, fast, and robust model, named EnviroDetaNet, which integrates molecular environment information. EnviroDetaNet employs an E(3)-equivariant message-passing neural network combining intrinsic atomic properties, spatial features, and environmental information, allowing it to comprehensively capture both local and global molecular information. Compared to state-of-the-art models, EnviroDetaNet excels in various predictive tasks and maintains high accuracy even with a 50% reduction in training data, demonstrating strong generalization capabilities. Ablation studies confirm that molecular environment information is crucial for improving model stability and accuracy. EnviroDetaNet also shows outstanding performance in spectral predictions for complex molecular systems, making it a powerful tool for accelerating molecular discovery.
Electric fields imbue enzyme reactivity by aligning active site fragment orbitals
Authors: Eberhart Mark , Wilson Timothy , Jones Travis , Alexandrova Anastassia
Published: September 2024

It is broadly recognized that intramolecular electric fields, produced by the protein scaffold and acting on the active site, facilitate enzymatic catalysis. This field effect can be described by several theoretical models, each of which is intuitive to varying degrees. In this contribution, we show that a fundamental effect of electric fields is to generate electrostatic potentials that facilitate the energetic alignment of reactant frontier orbitals. We apply this model to demystify the impact of electric fields on high-valent iron–oxo heme proteins: catalases, peroxidases, and peroxygenases/monooxygenases. Specifically, we show that this model easily accounts for the observed field-induced changes to the spin distribution within peroxidase active sites and explains the transition between epoxidation and hydroxylation pathways seen in Cytochrome P450 active site models. Thus, for the intuitive interpretation of the chemical effect of the field, the strategy involves analyzing the response of the orbitals of active site fragments, and their energetic alignment. We note that the energy difference between fragment orbitals involved in charge redistribution acts as a measure for the chemical hardness/softness of the reactive complex. This measure, and its sensitivity to electric fields, offers a single parameter model from which to quantitatively assess the effects of electric fields on reactivity and selectivity. Thus, the model provides an additional perspective to describe electrostatic preorganization and offers ways for its manipulation.
