General health literacy, COVID-19-related health literacy, and protective behaviors: evidence from a population-based study in Japan
Authors: Murakami Keiko , Kuriyama Shinichi , Hashimoto Hideki 
Published: September 2023

IntroductionHealth literacy (HL) can be regarded as a key element of non-pharmaceutical interventions used in emergency responses. The present study aimed to determine the associations of combinations of general HL and COVID-19-related HL with COVID-19 protective behaviors and healthy lifestyle behaviors.MethodsA questionnaire survey was conducted from December 2020 to January 2021 among residents in Japanese metropolitan areas. Valid responses were received from 1,443 residents. The levels of HL were categorized into four groups: low level in both HLs (reference), high level in general HL only, high level in COVID-19-related HL only, and high level in both HLs. The total scores of eight COVID-19 protective behaviors were dichotomized into low and high adherence. Healthy lifestyle behaviors included healthy and balanced diet, adequate sleep, and regular exercise. Poisson regression analyses were conducted to examine the associations between the HL groups and high adherence to COVID-19 protective behaviors.ResultsHigh level in COVID-19-related HL only was associated with high adherence to COVID-19 protective behaviors [prevalence ratio (PR), 1.25; 95% confidence interval (CI), 1.09–1.45], while high level in general HL only was associated with healthy and balanced diet (PR, 1.49; 95% CI, 1.04–2.13), adequate sleep (PR, 1.46; 95% CI, 1.02–2.10), and regular exercise (PR, 2.00; 95% CI, 1.29–3.13). High level in both HLs showed the highest prevalence of high adherence to COVID-19 protective behaviors and healthy lifestyle behaviors.ConclusionThese findings indicate that COVID-19-related HL and general HL can both be considered to enhance protective behaviors.

Published: September 2023

BackgroundExhaled SARS-CoV-2 can be detected on face masks. We compared tests for SARS-CoV-2 RNA on worn face masks and matched saliva samples.MethodsWe conducted this prospective, observational, case-control study between December 2021 and March 2022. Cases comprised 30 in-center hemodialysis patients with recent COVID-19 diagnosis. Controls comprised 13 hemodialysis patients and 25 clinic staff without COVID-19 during the study period and the past 2 months. Disposable 3-layer masks were collected after being worn for 4 hours together with concurrent saliva samples. ThermoFisher COVID-19 Combo Kit (A47814) was used for RT-PCR testing.ResultsMask and saliva testing specificities were 99% and 100%, respectively. Test sensitivity was 62% for masks, and 81% for saliva (p = 0.16). Median viral RNA shedding duration was 11 days and longer in immunocompromised versus non-immunocompromised patients (22 vs. 11 days, p = 0.06, log-rank test).ConclusionWhile SARS-CoV-2 testing on worn masks appears to be less sensitive compared to saliva, it may be a preferred screening method for individuals who are mandated to wear masks yet averse to more invasive sampling. However, optimized RNA extraction methods and automated procedures are warranted to increase test sensitivity and scalability. We corroborated longer viral RNA shedding in immunocompromised patients.
Spontaneous rupture of a splenic artery aneurysm causing acute abdomen in a 19-year-old male patient: a case report
Authors: Njoum Yumna , Barqawi Abdallah Deghles , Maree Mohammed 
Published: September 2023

IntroductionA splenic artery aneurysm is considered an abnormal dilatation of the splenic artery layers greater than 1 cm in diameter. First described by Beaussier in 1770, it affects 1% of the population but carries a major risk for life-threatening complications of rupture in 3%–10% of cases regardless of its congenital or acquired etiology. The presentation is highly variable, from asymptomatic incidental discovery during routine imaging to aneurysmal rupture causing acute abdomen, massive gastrointestinal bleeding, and hemorrhagic shock.Case presentationHerein, we present a 19-year-old male patient who presented with epigastric pain and abdominal rigidity associated with a moderate amount of free peritoneal fluid that was found to be a ruptured SAA after immediate laparoscopy, which was successfully managed with splenectomy.ConclusionSAAs are a rare etiology of acute abdomen and hemorrhagic shock but have a very high risk of mortality even upon immediate intervention, requiring a very high level of vigilance and a low threshold for surgical intervention in unstable patients presenting with abdominal pain.
Thermodynamic and Dynamic Transitions and Interaction Aspects in Reorientation Dynamics of Molecular Probe in Organic Compounds: A Series of 1-alkanols with TEMPO
Authors: Bartoš Josef , Švajdlenková Helena 
Published: September 2023

The spectral and dynamic properties of 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) in a series of 1-alkanols ranging from methanol to 1-decanol over a temperature range 100–300 K were investigated by electron spin resonance (ESR). The main characteristic ESR temperatures connected with slow to fast motion regime transition; T50G ‘s and TX1fast ‘s are situated above the corresponding glass temperatures, Tg, and for the shorter members, the T50G ‘s lie above or close to melting point, Tm, while the longer ones the T50G < Tm relationship indicates that the TEMPO molecules are in the local disordered regions of the crystalline media. The T50G ‘s and especially TX1fast ‘s are compared with the dynamic crossover temperatures, TXVISC = 8.72M0.66, as obtained by fitting the viscosity data in the liquid n-alkanols with the empirical power law. In particular, for NC > 6, the TX1fast ‘s lie rather close to the TXVISC resembling apolar n-alkanes [PCCP 2018,20,11145-11151], while for NC < 6, they are situated in the vicinity of Tm. The absence of a coincidence for lower1-alkanols indicates that the T50G is significantly influenced by the mutual interaction between the polar TEMPO and the protic polar medium due to the increased polarity and proticity destroyed by the larger-scale melting transition.

Published: September 2023

Miscellaneous imines and acyl hydrazones were prepared from 5-nitrofuraldehyde and 5-nitrothiophene-2-carboxaldehyde. Their activities against Toxoplasma gondii and Leishmania major parasites were evaluated. Promising antiparasitic effects and selectivities were observed for certain acyl hydrazones and imines. Cobalt(II) and copper(II) complexes conserved the high anti-Toxoplasma activities of 3-hydroxy-2-naphthoic carboxyl hydrazone (2a). In addition, sound activities against L. major promastigotes were observed for various analogs of 2a (2b and 2i) and pyrid-2-ylpyrazole-based imines (3g and 3h). Relatively low toxicities to kidney cells and macrophages indicate promising selectivity profiles for these compounds.

Rapid Energy Exchange between In Situ Formed Bromine Vacancies and CO
2
Molecules Enhances CO
2
Photoreduction

Published: September 2023

Photocatalytic reduction of CO
2
into fuels provides a prospective tactic for regulating the global carbon balance utilizing renewable solar energy. However, CO
2
molecules are difficult to activate and reduce due to the thermodynamic stability and chemical inertness. In this work, we develop a novel strategy to promote the adsorption and activation of CO
2
molecules via the rapid energy exchange between the photoinduced Br vacancies and CO
2
molecules. Combining in situ continuous wave-electron paramagnetic resonance (cw-EPR) and pulsed EPR technologies, we observe that the spin–spin relaxation time (T
2
) of BiOBr is decreased by 198 ns during the CO
2
photoreduction reaction, which is further confirmed by the broadened EPR linewidth. This result reveals that there is an energy exchange interaction between in situ formed Br vacancies and CO
2
molecules, which promotes the formation of high-energy CO
2
molecules to facilitate the subsequent reduction reaction. In addition, theoretical calculations indicate that the bended CO
2
adsorption configuration on the surface of BiOBr with Br vacancies caused the decrease of the lowest unoccupied molecular orbital of the CO
2
molecule, which makes it easier for CO
2
molecules to acquire electrons and get activated. In situ diffuse reflectance infrared Fourier transform spectroscopy further shows that the activated CO
2
molecules are favorably converted to key intermediates of COOH*, resulting in a CO generation rate of 9.1 μmol g
−1
h
−1
and a selectivity of 100%. This study elucidates the underlying mechanism of CO
2
activation at active sites and deepens the understanding of CO
2
photoreduction reaction.

Authors: Кукунин Д.С. , Когновицкий О.С. , Березкин А.А. , Киричек Р.В. 
Published: September 2023

Основная идея данной работы заключается в представлении кодов Рида-Соломона как рекуррентных последовательностей, построенных на основе характеристического полинома. Это наделяет данный вид кодов свойствами, присущими двоичным последовательностям максимальной длины, и также обеспечивает их обработку двойственным базисом поля Галуа. Вместе с этим в статье показана возможность кодового уплотнения эквивалентных последовательностей Голда на основе дуальных кодов Рида-Соломона. Предложенные в работе методы обработки рекуррентных последовательностей в дальнейшем могут найти применение, прежде всего, в задачах расширения спектра сигнала с последующим кодовым разделением каналов, а также для организации механизмов гарантированной доставки информации в потоковых системах передачи данных реального времени.
The main idea of this paper is to represent Reed-Solomon codes as recurrent sequences constructed on the basis of a characteristic polynomial. This gives this type of codes the properties inherent in binary maximum length sequences and also ensures their processing by the dual basis of the Galois field. At the same time, the article shows the possibility of code compaction of Reed-Solomon dual codes into Gold codes. The methods of processing recurrent sequences proposed in the article can later be used to organize mechanisms for guaranteed information delivery in real-time streaming data transmission systems.

Обоснована целесообразность использования алгебраических линейных кодовдля обнаружения и коррекции ошибок в специализированных ЭВМ, позволяющих по отношению к мажоритарному методу и методу дублирования существенно сократить аппаратурные затраты и использовать для этих целей 10−30% резервного оборудования. Установлена возможность использования корректирующих кодов для исправления ошибок процессора при обработке информации. Рассмотрен пример использования кода Хемминга для коррекции ошибок процессора при выполнении операции сложения. Показано, что существующие алгебраические коды не могут быть использованы для контроля операций вычитания и деления, так как не позволяют контролировать логическую операцию инвертирования, необходимую для представления отрицательного числа в дополнительном коде. Разработан алгоритм построения кода, позволяющего контролировать логическую операцию отрицания и, следовательно, представления отрицательного числа в дополнительном коде. Определены параметры разработанного кода. Рассмотрен пример использования предлагаемого кода для контроля арифметической операции вычитания.
The expediency of using algebraic linear codes for detecting and correcting errors in specialized computers is substantiated, which allows, in relation to the majority method and the duplication method, to significantly reduce hardware costs and use 10−30% of reserve equipment for these purposes. The possibility of using corrective codes to correct processor errors during information processing has been established. An example of using a Hamming code to correct processor errors during an addition operation is considered. It is shown that the existing algebraic codes cannot be used to control the arithmetic operations of subtraction and division, since they do not allow controlling the logical inversion operation necessary to represent a negative number in an additional code. An algorithm for constructing a code has been developed that makes it possible to control the logical operation of negation and, consequently, the representation of a negative number in an additional code. The parameters of the developed code are determined. An example of using the proposed code to control the arithmetic operation of subtraction is considered.

Improvement of emission intensity of PbS quantum dots in thick silica shell by initial coating in organic solvent
Authors: Mukai Kohki , Suzuki Sena , Roppongi Haruto 
Published: September 2023

Abstract
Positioning of colloidal quantum dots (QDs) by nanoholes is applicable to fabricating quantum devices such as quantum circuits. A silica coating technique that facilitates the positioning manages the effective size of QDs while preserving the quantum state inside. In the reverse micelle method, which is commonly used for the silica coating, optical properties deteriorate due to the exposure of QD surface to moisture within the reverse micelle. We studied a thin silica coating on the surface of PbS QDs by pyrolyzing tetraethyl orthosilicate in an organic solvent before forming a thick silica shell by the reverse micelle method. As a result, highly luminous silica-coated PbS QDs with a diameter of about 110 nm were realized.
