Published: July 2023

A mathematical model was proposed to study the microkinetics of esterification reaction of oleic acid with ethanol over prepared HY zeolite catalyst. The catalyst was prepared from Iraqi kaolin source and its properties were characterized by different techniques. The esterification was done under different temperature (40 to 70˚C) with 6:1 for molar ratio of ethanol to oleic acid and 5 % catalyst loading.
The microkinetics study was done over two period of time each period was examined individually to calculate the reaction rate constant and activation energy. The impact of the mass transfer resistance to the reactant was also investigated; two different studies have been accomplished to do this purpose.
The effect of the external mass transfer resistance was studied by exploring different stirring speed (400 to 800 rpm). The results show that, the oleic acid conversion increase with increasing the stirring speed until reached 600 rpm, after this rpm the conversion doesn’t increase significantly, which mean that, the effect of external mass transfer resistance was eliminated. The activation energy for the first period is equal to 41.84 kJ/mol while in the second period is equal to 52.03 kJ/mol. The Thiele modulus calculation results show that there is no effect of mass transfer on the reaction inside the catalyst pores.

Published: July 2023

Mycobacteriophages are viruses that infect members of genus Mycobacterium. Because of the rise in antibiotic resistance in mycobacterial diseases such as tuberculosis, mycobacteriophages have received renewed attention as alternative therapeutic agents. Mycobacteriophages are highly diverse, and, on the basis of their genome sequences, they are grouped into 30 clusters and 10 singletons. In this article, we have described the isolation and characterization of a novel mycobacteriophage Kashi-VT1 (KVT1) infecting Mycobacterium &gt;smegmatis mc2 155 (M. smegmatis) and Mycobacterium fortuitum isolated from Varanasi, India. KVT1 is a cluster K1 temperate phage that belongs to Siphoviridae family as visualized in transmission electron microscopy. The phage genome is 61,010 base pairs with 66.5% Guanine/Cytosine (GC) content, encoding 101 putative open reading frames. The KVT1 genome encodes an immunity repressor, a tyrosine integrase, and an excise protein, which are the characteristics of temperate phages. It also contains genes encoding holin, lysin A, and lysin B involved in host cell lysis. The one-step growth curve demonstrated that KVT1 has a latency time of 90 min and an average burst size of 101 phage particles per infected cell. It can withstand a temperature of up to 45°C and has a maximum viability between pH 8 and 9. Some mycobacteriophages from cluster K are known to infect the pathogenic Mycobacterium tuberculosis (M. tuberculosis); hence, KVT1 holds potential for the phage therapy against tuberculosis, and it can also be engineered to convert into an exclusively lytic phage.

Published: July 2023

IntroductionOriginally regarded as garnish greens, microgreens are increasingly valued for their nutritional profile, including their mineral content.MethodsA study was conducted under controlled environmental conditions utilizing a selection of seventeen microgreen species belonging to seven different botanical families to investigate the genetic variation of macro- and micro-minerals and nitrate (NO3-) content. Plants were grown in a soilless system using a natural fiber mat as the substrate. After germination, microgreens were fertigated with a modified half-strength Hoagland solution prepared using deionized water and without adding microelements. At harvest (10 to 19 days after sowing, based on the species), yield components were measured and dry tissue samples were analyzed for the concentration of total nitrogen (N), NO3-, P, K, Ca, Mg, S, Na, Fe, Zn, Mn, Cu, and B. Results and discussionGenotypic variations were observed for all of the examined parameters. Nitrogen and K were the principal macronutrients accounting for 38.4% and 33.8% of the total macro-minerals concentration, respectively, followed in order by Ca, P, S, and Mg. Except for sunflower (Helianthus annuus L.), all the tested species accumulated high (1,000-2,500 mg kg-1 FW) or very high (&gt;2,500 mg kg-1 FW) NO3- levels. Eight of the studied species had a K concentration above 300 mg 100 g-1 FW and could be considered as a good dietary source of K. On the other hand, scallion (Allium fistulosum L.), red cabbage (Brassica oleracea L. var. capitata), amaranth (Amaranthus tricolor L.), and Genovese basil (Ocinum basilicum L.) microgreens were a good source of Ca. Among micro-minerals, the most abundant was Fe followed by Zn, Mn, B, and Cu. Sunflower, scallion, and shiso (Perilla frutescens (L.) Britton) were a good source of Cu. Moreover, sunflower was a good source of Zn, whereas none of the other species examined could be considered a good source of Fe and Zn, suggesting that supplementary fertilization may be required to biofortify microgreens with essential microminerals. In conclusion, the tested microgreens can be a good source of minerals showing a high potential to address different dietary needs; however, their yield potential and mineral profile are largely determined by the genotype.

Published: July 2023

BackgroundEmotion dysregulation (ED) is increasingly under investigation as a cross-disorder trait, and is by some considered as the core feature in mental disorders. The aims of this study were to scrutinize the overlapping and distinct characteristics of ED for internalizing, externalizing and neurodevelopmental disorders and to identify the most pertinent ED characteristics to guide clinicians in treatment choice.MethodsInformation on clinical diagnosis (Attention Deficit/Hyperactivity Disorder ADHD, Autism Spectrum Disorder, Oppositional Defiant Disorder/Conduct Disorder, Anxiety and Mood Disorders), ED (measured by the CBCL-Emotion Dysregulation Index), Quality of Life (Qol, measured by the Kidscreen-27), and treatment duration (measured by Electronic Health Records) was retrieved from two large samples of toddlers (1.5–5  year old; N = 1,544) and school aged children (6–18 year old; N = 7,259). Frequency scores and logistic regression were used to study symptom profiles of ED, as measured with CBCL-EDI, across all disorders. Linear regression was used to determine the predictive value of ED (CBCL-EDI total score) regarding QoL and treatment duration in addition to—and in interaction with—clinical diagnosis.ResultsAcross disorders, equal levels of total ED were found, which predicted lower QoL and a longer treatment duration in addition to clinical diagnosis. The majority of items (11/15 and 16/18) were of equal relevance to the disorders; items that were not, largely reflected disorder specific DSM definitions (i.e., externalizing symptoms in ODD/CD and internalizing symptoms in Anxiety and Mood disorders).ConclusionED is a clinically useful cross-disorder trait to predict severity of impairment as well as required treatment duration. In addition, ED is largely composed of shared features across disorders, with certain disorder specific colored elements.

Comércio, escravidão e conexões atlânticas: o caso de Pedro da Silva (Maranhão – Século XVIII)
Authors: Meireles Marinelma Costa , Araújo Patrício Câmara 
Published: July 2023

O Novo Mundo que emergiu na modernidade é, antes de tudo, fruto de experiências vivenciadas pelas sociedades que se interligaram no/e através do Atlântico. Portugueses, africanos e “americanos” compartilharam práticas advindas da circulação de pessoas, mercadorias e significados. Esse mundo, composto e lapidado por diferentes culturas, trouxe à tona um ambiente permeado de impressões, subjetividades e experiências, sobrevindo do movimento, do ir e vir de pessoas, de uma margem a outra do oceano. A trajetória do forro Pedro da Silva, cabo-verdiano - que morou no reino e migrou para o Maranhão no século XVIII, e nessa localidade desejou se casar – é um espaço privilegiado para observarmos essas dinâmicas. Para alcançar o seu intento, ele precisava provar às autoridades vigilantes do Tribunal Eclesiástico do Maranhão que era viúvo. A busca pela “justificação de viuvez” desvela a história desse sujeito em conexão com três espaços: África, Europa e América, tendo como pano de fundo a ação da Companhia Geral do Grão-Pará e Maranhão (1755), empreendimento mercantil responsável pelo comércio de africanos escravizados para o norte da América Portuguesa. O objetivo deste estudo foi analisar as conexões do Maranhão Colonial com o mundo atlântico, na segunda metade do século XVIII, tendo como fio condutor as experiências de Pedro da Silva. Para tanto, faremos abordagem qualitativa, de foco exploratório, por meio de pesquisa documental no campo da micro-história.
Evaluation of Subjective Satisfaction with Orthokeratology: A Pilot Study
Authors: Rajeev Narayanan , Wu Titus , Low Jamie 
Published: July 2023

Background: This study evaluates subjective satisfaction levels among Singapore-based OK lens wearers and investigates what motivated them to go for OK.
Methods: A customised survey form was administered. Participants’ perceptions were assessed along the dimensions of vision, facial appearance, satisfaction, activity, and symptoms. The participants also had to indicate what motivated them to go for OK. The remaining questions focussed on the participants’ demographics and OK related routines since the survey was designed to be a stand-alone questionnaire that is suitable for a specialised optometry setting.
Results: OK participants (n=100) demonstrated an overall positive experience across vision, facial appearance, satisfaction, and activity dimensions. Most participants either did not experience or only occasionally experienced the surveyed symptoms. Seeing clear throughout the day (71%), myopia control (70%), and convenience for school/occupation (65%) and sports (59%) were the most popular reasons why participants were on OK. Better appearance (36%), and discomfort with spectacles (34%) and contact lenses (11%) were the other motivating factors.
Conclusion: Orthokeratology is associated with high levels of satisfaction rate. Seeing clear throughout the day, myopia control and convenience for day-to-day activities are the key reasons why participants are on OK treatment. Optometrists, while ensuring rigorous compliance to lens care regimen and good adherence to routine follow-ups, may positively recommend orthokeratology not just for children for the purpose of myopia control but to potentially anyone, who wants to be free of day-time myopic refractive correction.

Published: July 2023

AbstractDravet syndrome (DS) is a monogenic, often refractory, epilepsy resultant from SCN1A haploinsufficiency in humans. A novel therapeutic target in DS that can be engaged in isolation or as adjunctive therapy is highly desirable. Here, we demonstrate reduced expression of the rodent glutamate transporter type 1 (GLT‐1) in a DS mouse model, and in wild type mouse strains where Scn1a haploinsufficiency is most likely to cause epilepsy, indicating that GLT‐1 depression may play a role in DS seizures. As GLT‐1 can be upregulated by common and safe FDA‐approved medications, this strategy may be an attractive, viable, and novel avenue for DS treatment.

AbstractTitanium alloys are commonly used as biomaterials in musculoskeletal applications, but their long‐term efficacy can be limited by wear and corrosion, stress shielding, and bacterial colonization. As a promising alternative, bulk metallic glasses (BMGs) offer superior strength and corrosion resistance, but the influence of their chemical composition on their bioactivity remains largely unexplored. This study, therefore, aims to examine how the surface chemistry of palladium (Pd)‐, platinum (Pt)‐, and titanium (Ti)‐based BMGs can steer their response to biological systems. The chemical composition of BMGs governs their thermophysical and mechanical properties, with Pd‐based BMGs showing exceptional glass‐forming ability suitable for larger implants, and all BMGs exhibiting a significantly lower Young's modulus than Ti‐6Al‐4 V (Ti64), suggesting a potential to reduce stress shielding. Although BMGs feature copper depletion at the near surface, their surface chemistry remains more stable than that of Ti64 and supports blood biocompatibility. Fibrin network formation is heavily dependent on BMGs’ chemical composition and Ti‐based BMGs support thicker fibrin network formation than Ti64. Furthermore, BMGs outperform Ti64 in promoting mineralization of human bone progenitor cells and demonstrate antimicrobial properties against Staphylococcus aureus in a surface chemistry‐dependent manner, thereby indicating their great potential as biomaterials for musculoskeletal applications.
Electrically Sensitive Plasmonic Photonic Crystals for Dynamic Upconversion Manipulation

Published: July 2023

AbstractLocal optical field modulation using plasmonic materials or photonic crystals provides a powerful strategy for enhancing upconversion emission of lanthanide‐doped upconversion nanocrystals (UCNPs). However, it is restricted to static UC enhancement and the corresponding dynamic modulation of UC is yet to be reported, limiting its practical applications in information devices. Here, a dynamic UC modulation system is reported through electric stimulation by integrating UCNPs with electrically sensitive WO3−x plasmonic photonic crystals (PPCs). The tunable emission enhancement of UCNPs varying from five to 26 folds is achieved in WO3−x PPCs/UCNPs hybrids through external electric stimulation within +1.6 and −1.6 V. It stems from the reversible control of the photonic bandgaps and localized surface plasmon resonance of WO3−x PPCs, ascribed to the variation of refractive index and oxygen vacancy of WO3−x, induced by the reversible change of atomic ratio of W5+ to W6+ under different applied voltages. Moreover, the electrically triggered information encryption devices are developed, employing a programmable logic gate array based on WO3−x PPCs/UCNPs with the ability to convert information‐encrypted electrical signals into visible patterns. These observations offer a new attempt to manipulate the UC and will simulate the new applications in the display and optical storage devices.

AbstractLayered ammonium vanadate materials exhibit significant mass‐specific capacity and ion transport rate due to their small molecular weight and large ionic radius. However, the strong electrostatic interactions of Zn2+ and V–O bonds and the fragile ionic bonding of N‐H…O bonds hinder their development. Therefore, this work reports Mg2+ doping NH4V4O10 materials accompanied by flower‐like morphology to lower the migration energy barrier and inhibit amine dissolution. Owing to the 3D‐flower‐like morphology and the combined impact of Mg2+ and structural water, the binding of Zn2+…V‐O is significantly enhanced and additional ion channels were constructed. Pre‐intercalated Mg2+ enhances the structural integrity and prevents irreversible deammoniation from obtaining excellent cyclic stability. Density functional theory (DFT) calculations show that MNVO provides a smoother Zn2+ diffusion path with a lower migration barrier. Benefited from these advantages, the MNVO cathode exhibits a high specific capacity of 410 mAh g−1 at 0.1 A g−1, satisfactory cyclic stability (90.2 % capacity retention at 10 A g−1 after 5000 cycles), and capable rate ability (118 mAh g−1 at 25 A g−1) within 0.4‐1.5 V. Furthermore, the zinc ion storage mechanism in the MNVO cathode is investigated through multiple analyses.
