Authors: Mohammed K. , Iduh M. U. , Sani M. , Mohammed Y.
Published: March 2023

Background: Soil-transmitted helminths are among the neglected tropical disease parasites of humans and one of the major public health burdens in developing countries, particularly Sub-Saharan Africa. It is estimated that about 1.5 billion people are affected worldwide.

Aims: The study was aimed to determine the prevalence and risk factors of Soil-transmitted helminths infection among primary school children.

Study Design: This was a cross sectional, descriptive study.

Place and Duration of Study: The study was conducted among primary school children within the age of 4-15 years old in Sokoto South, Wamakko, Yabo and Dange Shuni local government areas of Sokoto State from February 2021 to July 2021.

Methodology: Faecal samples of 252 children were collected and analyzed using formol-ether concentration technique.

Results: An overall prevalence of 6.0% was recorded. Differential prevalence of parasite species showed 6.7% Ascaris lumbricoide, and 93.3% hookworm infection. There was high prevalence among Males (7.2%) than Females (4.0%). The age group 10-12 has the high prevalence of 9.8%. The high prevalence of 9.5% was obtained in Yabo and Sokoto South respectively. Tap water and water closet users have the lowest prevalence of 5.3%. High prevalence of 33.3% was recorded among borehole users contaminated with soil.

Conclusion: The total low prevalence of soil-transmitted helminths may be as a result of improved awareness of the Soil-transmitted helminths in the study area. The government, non-government agencies should help in the provision of social amenities to ensure the total eradication of these diseases. The teaching of health education in both private and public schools should be encouraged by the government.

Rethinking the Role of Excess/Residual Lead Iodide in Perovskite Solar Cells
Authors: Gao You , Raza Hasan , Zhang Zhengping , Chen Wei , Liu Zonghao
Published: March 2023

It is widely believed that excess/residual lead iodide (PbI2) can affect the performance of perovskite solar cells . Moderate PbI2 can enhance efficiency by passivating defects, while extremely active PbI2 leads to non‐negligible hysteresis effects and reduces device stability. Although several efforts are made to investigate the role of excess PbI2, its impact is still underestimated. Recent advances further demonstrate the extraordinary potential of modifying excess PbI2; however, a comprehensive study is required to obtain a deeper understanding. Herein, the important breakthroughs regarding excess PbI2 are reviewed and the mechanism of excess PbI2 in terms of efficiency and stability is rethought. In addition, the origins, verification, and regulation of residual PbI2 are summarized.

Published: March 2023

Decreasing the Ti3+ defect concentration in SrTiO3 is recognized as the focus of seeking a perfect photocatalytic activity. However, the defect‐engineered SrTiO3 by doping different low‐valence metal ions have no similarly good activity in overall water spitting, of which the reason has not been determined. Here, Na+, K+, and Cs are deliberately doped in SrTiO3 to obtain a close low‐level concentration of Ti3+ defect for comparison. An interesting phenomenon is found that the K‐doped SrTiO3 has a higher Ti3+ concentration than others but with a better intrinsic photocatalytic activity. The analysis of band structure and charge‐carriers behavior indicates the formation of a deep‐state defect in Na or Cs‐doped SrTiO3, leading to a decrease in photocatalytic activity. With the density functional theory calculation and synchrotron radiation characterization, the differences in A‐site‐metal ionic polarization are found to localize some defect charge, accompanied by uneven structural relaxation. As a result, the deep‐state defect can form in the area containing some group of atoms around the higher‐polarization metal ions, limiting the activity. This study further complements the important effect of doping ions on defect state in addition to the Ti3+ defect concentration in theory, for designing defect engineering in SrTiO3.

Published: March 2023

Tissue engineering aims at replicating tissues and organs to develop applications in vivo and in vitro. In vivo, by engineering artificial constructs using functional materials and cells to provide both physiological form and function. In vitro, by engineering three‐dimensional (3D) models to support drug discovery and enable understanding of fundamental biology. 3D culture constructs mimic cell–cell and cell–matrix interactions and use biomaterials seeking to increase the resemblance of engineered tissues with its in vivo homologues. Native tissues, however, include complex architectures, with compartmentalized regions of different properties containing different types of cells that can be captured by multicompartment constructs. Recent advances in fabrication technologies, such as micropatterning, microfluidics or 3D bioprinting, have enabled compartmentalized structures with defined compositions and properties that are essential in creating 3D cell‐laden multiphasic complex architectures. This review focuses on advances in engineered multicompartment constructs that mimic tissue heterogeneity. It includes multiphasic 3D implantable scaffolds and in vitro models, including systems that incorporate different regions emulating in vivo tissues, highlighting the emergence and relevance of 3D bioprinting in the future of biological research and medicine.

Negative‐capacitance field‐effect transistors (NC‐FETs) have gathered enormous interest as a way to reduce subthreshold swing (SS) and overcome the issue of power dissipation in modern integrated circuits. For stable NC behavior at low operating voltages, the development of ultrathin ferroelectrics (FE), which are compatible with the industrial process, is of great interest. Here, a new scalable ultrathin ferroelectric polymer layer is developed based on trichloromethyl (CCl3)‐terminated poly(vinylidene difluoride‐co‐trifloroethylene) (P(VDF‐TrFE)) to achieve the state‐of‐the‐art performance of NC‐FETs. The crystalline phase of 5–10 nm ultrathin P(VDF‐TrFE) is prepared on AlOX by a newly developed brush method, which enables an FE/dielectric (DE) bilayer. FE/DE thickness ratios are then systematically tuned at ease to achieve ideal capacitance matching. NC‐FETs with optimized FE/DE thickness at a thickness limit demonstrate hysteresis‐free operation with an SS of 28 mV dec−1 at ≈1.5 V, which competes with the best reports. This P(VDF‐TrFE)‐brush layer can be broadly adapted to NC‐FETs, opening an exciting avenue for low‐power devices.

Published: March 2023

The Hoffmeister effect of inorganic salts is verified as a promising way to toughen hydrogels, however, the high concentration of inorganic salts may be accompanied by poor biocompatibility. In this work, it is found that polyelectrolytes can obviously elevate the mechanical performances of hydrogels through the Hoffmeister effect. The introduction of anionic poly(sodium acrylate) into poly(vinyl alcohol) (PVA) hydrogel induces the aggregation and crystallization of the PVA to boost the mechanical properties of the resulting double‐network hydrogel: elevation of 73, 64, 28, 135, and 19 times in the tensile strength, compressive strength, Young's modulus, toughness, and fracture energy compared with poly(acrylic acid), respectively. It is noteworthy that the mechanical performances of the hydrogels can be flexibly tuned by the variation of polyelectrolyte concentration, ionization degree, relative hydrophobicity of the ionic component, and polyelectrolyte type in a wide range. This strategy is verified to work for other Hoffmeister‐effect‐sensitive polymers and polyelectrolytes. Also, the introduction of urea bonds into the polyelectrolyte can further improve the mechanical properties and antiswelling capability of hydrogels. As a biomedical patch, the advanced hydrogel can efficiently inhibit hernia formation and promote the regeneration of soft tissues in an abdominal wall defect model.
Ecofriendly Polymer–Graphene‐Based Conductive Ink for Multifunctional Printed Electronics
Authors: Joshi Shalik Ram , Kumar Sumit , Kim Sunghwan
Published: March 2023

The ongoing research on printed and flexible electronics is primarily focused on conductive three‐dimensional (3D) print patterning. However, due to the nonhomogeneous distribution of conductive elements in a polymer matrix and their tendency to shrink, 3D‐printed patterns often suffer from low‐printing accuracies and poor mechanical and electrical properties. Herein, poly(vinyl butyral‐co‐vinyl alcohol‐co‐vinyl acetate) (PVBVA) is reinforced with microwave‐exfoliated graphene to develop a conductive ink for 3D printing. Compared with the pure PVBVA patterns, the PVBVA/graphene patterns exhibit a high‐electrical conductivity, a twofold enhancement in tensile strength, an improved printing accuracy, and a high stability because of the graphene addition. The PVBVA/graphene inks flow well during the printing; loading of up to 0.1 wt% graphene in the PVBVA gel results in notable changes in the rheological properties of the ink. The printed conductive patterns show a high flexibility suitable for wearable electronics. Additionally, multifunctional electronic operations such as photoinduced heating, temperature sensing, and motion sensing are possible. This study may pave the way for the development of a new class of smart wearable electronics for healthcare and soft robotics.
Engineering Escherichia coli to Utilize Erythritol as Sole Carbon Source
Authors: Ba Fang , Ji Xiangyang , Huang Shuhui , Zhang Yufei , Liu Wan‐Qiu , Liu Yifan , Ling Shengjie , Li Jian
Published: March 2023

Erythritol, one of the natural sugar alcohols, is widely used as a sugar substitute sweetener in food industries. Humans themselves are not able to catabolize erythritol and their gut microbes lack related catabolic pathways either to metabolize erythritol. Here, Escherichia coli (E. coli) is engineered to utilize erythritol as sole carbon source aiming for defined applications. First, the erythritol metabolic gene cluster is isolated and the erythritol‐binding transcriptional repressor and its DNA‐binding site are experimentally characterized. Transcriptome analysis suggests that carbohydrate metabolism‐related genes in the engineered E. coli are overall upregulated. In particular, the enzymes of transaldolase (talA and talB) and transketolase (tktA and tktB) are notably overexpressed (e.g., the expression of tktB is improved by nearly sixfold). By overexpression of the four genes, cell growth can be increased as high as three times compared to the cell cultivation without overexpression. Finally, engineered E. coli strains can be used as a living detector to distinguish erythritol‐containing soda soft drinks and can grow in the simulated intestinal fluid supplemented with erythritol. This work is expected to inspire the engineering of more hosts to respond and utilize erythritol for broad applications in metabolic engineering, synthetic biology, and biomedical engineering.
Predicting the shape, size, and placement of adult human pubic symphyses
Authors: Adegboyega Mayowa T. , Jhanjar Sara , Grote Mark N. , Weaver Timothy D.
Published: March 2023

Objectives

When reconstructing fossil pelves, the articulation of the pelvic bones largely relies on subjective decisions by researchers. Different positionings at the pubic symphysis can affect the overall morphology of the pelvis and the subsequent biological interpretation associated with that individual or species. This study aims to reduce this subjectivity using quantitative models to predict pubic symphysis morphology.

Methods

We collected 3D landmarks and semilandmarks on the pubic symphysis and adjacent aspects on the CT scans of 103 adults. Using geometric morphometrics we, (1) quantified pubic symphysis morphology, (2) trained simple and two‐stage least‐squares linear regression models to predict pubic symphysis shape, and (3) assessed the shape variation in the sample. The model with the lowest prediction error was identified as the best model. Principal components analysis was used to explore the effects of each variable on shape and hypothetical shapes were generated from the model to illustrate these effects.

Results

The best model is a two‐stage least‐squares model that predicts pubic symphysis size at the first stage using additive effects of sex and age, then subsequently interacts pubic symphysis size with sex and age at the second stage to predict pubic symphysis shape. Other models with low prediction errors included variables reflecting pelvic size and breadth.

Conclusion

Linear regression modeling can be used to systematically predict pubic symphysis morphology. This method can be used in addition to other techniques to improve fossil reconstructions by more accurately estimating the morphology of this region of the pelvis.
The morphofunctional implications of the glenoid labrum of the glenohumeral joint in hominoids
Authors: Raventós‐Izard Georgina , Potau Josep Mª. , Casado Aroa , Pastor Juan F. , Arias‐Martorell Julia
Published: March 2023

Objectives

A morphocline of the glenoid cavity has been used to infer differences in locomotor behaviors; however, the glenoid cavity is surrounded by the glenoid labrum, a fibrocartilaginous structure that could influence the functionality of the glenoid. The objectives of this study are to explore the effects of the glenoid labrum on the area, depth, and morphology of the glenoid cavity in primates.

Materials and Methods

Photogrammetry was used to build 3D models of the glenoid, with and without the labrum, and three‐ (3D) and two‐dimensional (2D) geometric morphometrics (GM) was applied. 2D areas were collected from zenithal images for glenoids with and without labrum to evaluate the availability of articular surface area.

Results

In the 2D GM the morphocline is present in the dry‐bone sample but not with the presence of the glenoid labrum. In the 3D GM there are differences between species mainly concerning the depth of the glenoid cavity. 2D areas reveal that the amount of articular area of the glenoid cavity increases with the presence of the labrum, particularly in humans.

Discussion

The glenoid labrum changes the shape, increases the depth and the surface area of the glenoid cavity, particularly in humans. Therefore, the glenoid labrum might hold a functional role, increasing the stability of the glenohumeral joint of primates in general, and especially in humans.

Suitably configured allyl ethers of unsaturated cyclitols act as substrates of β‐glycosidases, reacting via allylic cation transition states. Incorporation of halogens at the vinylic position of these carbasugars, along with an activated leaving group, generates potent inactivators of β‐glycosidases. Enzymatic turnover of these halogenated cyclitols (F, Cl, Br) displayed a counter‐intuitive trend wherein the most electronegative substituents yielded the most labile pseudo‐glycosidic linkages. Structures of complexes with the Sulfolobus β‐glucosidase revealed similar enzyme‐ligand interactions to those seen in complexes with a 2‐fluorosugar inhibitor, the lone exception being displacement of tyrosine 322 from the active site by the halogen. Mutation of Y322 to Y322F largely abolished glycosidase activity, consistent with lost interactions at O5, but minimally affected (7‐fold) rates of carbasugar hydrolysis, yielding a more selective enzyme for unsaturated cyclitol ether hydrolysis.

Published: March 2023

Terpen‐Zyklasen bergen enormes synthetisches Potenzial, da sie in der Lage sind, komplexe Kohlenwasserstoffgerüste aus achiralen Ausgangsstoffen in einer einzigen kationischen Umlagerungskaskade zu generieren. Dieses synthetische Potenzial nutzbar zu machen, erwies sich jedoch aufgrund ihrer allgemein geringen katalytischen Leistung als schwierig. In dieser Studie enthüllen wir das katalytische Potenzial der Squalen‐Hopen‐Zyklase (SHC), indem wir uns ihre Proteinstruktur und Dynamik zunutze machen. Zunächst haben wir das aktive Zentrum und den Eingangstunnel des Enzyms synergistisch evolviert, um damit eine 397‐fach verbesserte (−)‐Ambroxid‐Synthase zu erzeugen. Unsere computergestützten Untersuchungen erklären, wie die eingeführten Mutationen zusammenarbeiten, um die Substrataufnahme, den Fluss und die Vorfaltung zu verbessern. Kinetische Untersuchungen zeigten jedoch eine Terpen‐induzierte Inaktivierung der membrangebundenen SHC als Hauptlimitierung für die Biokatalyse in vivo. Indem diese Erkenntnisse mit der verbesserten und stereoselektiven Katalyse des Enzyms kombinierten wurden, konnte eine Fütterungsstrategie angewendet werden, um 105 katalytische Umsätze zu übertreffen. Diese Ergebnisse haben das Potenzial die Lücke für eine breitere Anwendung von SHCs in der synthetischen Chemie zu schließen.

Fucose ist ein signalgebendes Kohlenhydrat, das am Ende der Glykosylierung angehängt wird. Es ist an einer Reihe von Prozessen beteiligt, z. B. an der Selectin‐abhängigen Leukozytenadhäsion oder an Pathogen‐Rezeptor‐Interaktionen. Massenspektrometrische Verfahren, die üblicherweise zur Bestimmung der Struktur von Glykanen eingesetzt werden, zeigen häufig Fucose‐haltige, chimäre Fragmente, die die Analyse verzerren. Die Umlagerung, die zu diesen Fragmenten führt – oft als Fucose‐Migration bezeichnet – ist seit mehr als 25 Jahren bekannt, aber die chemische Identität des Umlagerungsproduktes bleibt unklar. In dieser Arbeit kombinieren wir Ionenmobilitätsspektrometrie, Massenspektrometrie mit radikalinduzierter Dissoziation, kryogene IR‐Spektroskopie und Computersimulationen mittels Dichtefunktionaltheorie, um das Produkt der Umlagerung der prototypischen Trisaccharide Lewis x und Blutgruppe H2 zu bestimmen. Die Struktursuche ergibt, dass die Fucose, die mit einer α(1→6)‐glykosidischen Bindung an die Galaktose gebunden ist, das wahrscheinlichste Produkt ist.

Published: March 2023

Nature's way to construct highly complex molecular entities as part of biosynthetic pathways is unmatched by any chemical synthesis. Yet, relying on a cascade of native enzymatic transformations to achieve a certain target structure, biosynthesis is also significantly limited in its scope. In this study, non‐natural biocatalytic modules, a peroxidase‐mediated Achmatowicz rearrangement and a dehydrogenase‐catalyzed borrowing‐hydrogen‐type isomerization were successfully incorporated into an artificial metabolism, combining the benefits of traditional retrosynthesis with the elegance and efficacy of biosynthetic networks. In a highly streamlined process, the total synthesis of tricyclic angiopterlactone B was achieved in two steps operating entirely in an aqueous environment while relying mainly on enzymes as key reaction mediators.
The influence of the Milan approach: Five decades of intergenerational change. A conversation with Matteo Selvini
Authors: Amorin‐Woods Deisy , Selvini Matteo
Published: March 2023

The ‘Milan Approach’ made an enormous contribution to psychotherapy and psychiatry and has been viewed as a bedrock in the family therapy field. Mara Selvini‐Palazzoli made a revolutionary shift in the early 1970’s to abandon individual therapy and adopt family therapy to treat anorexia in young women. The goal of the three systemic principles; hypothesising, circularity and neutrality, proposed by the Milan Team is to elicit a useful method to interview families which encourages the production of meaningful information.

The Milan group took special care of language. Rather than overly focusing on the label and referring to schizophrenia as a diagnosis, for instance, they used the term ‘families in schizophrenic transaction’. This perspective more realistically explored the origin of problems while looking at ways how to effectively generate change. In the early stages of its development, heavily influenced by the work of the MRI, the team adopted a pragmatic and strategic approach, however the focus gradually shifted towards semantics and the story of the system. While the ‘systemic identity’ was the principal guiding principle, the model was also influenced by social constructionism.

This paper is a distillation of a conversation held with Matteo Selvini, son of Mara Selvini Palazzoli. We discussed the four key influential figures who developed the ‘Milan approach’, Selvini Palazzoli, Boscolo, Cecchin and Prata. The focus of the conversation is on Mara and on her influence shaping the approach, its evolution through the years leading to the creation of the Scuola di Psicoterapia Mara Selvini Palazzoli.

Matteo also shares his own influence in the evolution of the school through the intervening years. He explains the adapted version of the Milan approach and the amalgam of the original and emerging therapeutic concepts. His key messages to therapists are the importance of working in teams and client follow‐ups.
MOFTextile: Metal‐organic frameworks nanosheets incorporated cotton textile for selective vapochromic sensing and capture of pyridine
Authors: Abdelhamid Hani Nasser
Published: March 2023

Metal–organic frameworks (MOFs) improved several trends and are promising for industrial applications. However, current synthesis processes offer powder form, rendering their applications difficult. A simple solvothermal method offered an in situ growth of copper‐based MOFs, for example, CuBDC (BDC: benzene‐1,4‐dicarboxylic acid) into a cotton textile; the material was denoted as CuBDC@Textile. CuBDCTextile was used as a solid sensor and adsorbent for volatile organic compounds (VOCs). It exhibited good vapochromic properties that enabled a colorimetric detection of pyridine (Py) via naked eyes with high selectivity and good sensitivity. Adsorption of pyridine via pervaporation using CuBDC@Textile was recorded. CuBDCTextile is a flexible textile with a high adsorption capacity (137.9 mg g−1) toward pyridine. It offered dual functional: sensor probe and adsorbent. The synthesis of CuBDC@Textile and their excellent performance as a sensor and adsorbent are promising for further investigation of the “MOFs on textile materials” topic.
Effects of compositional parameters on morphology and rheological properties of HDPE/PVA blends

Published: March 2023

Polymeric blends are relevant for research and industry because of their versatility, being able to accomplish property tailoring with competitive cost and ease to scale up, when compared to the development of in‐reactor new polymers. Blends of thermoplastics, however, might have their morphology and properties altered upon processing, therefore, there is uncertainty to some outputs after melt processing. Therefore, having a fixed morphology that is capable of being further processed without significant changes have industrial and academic value. This work presents a comprehensive study of rheological properties and morphology of a selectively crosslinked blend of polyethylene (HDPE) and poly(vinyl alcohol) (PVA), where the effect of the following parameters are evaluated: dispersed phase (PVA) weight fraction, continuous phase (HDPE) rheological properties, compatibilizer (PE‐g‐MAh) and crosslinking agent (maleic anhydride) content. Overall, melt complex viscosity and elasticity have increased with PVA weight fraction and HDPE viscosity. The compatibilizer content has not severely affected melt rheology, although it influenced blend morphology. Crosslinking agent content affected melt rheology and glass transition temperature in a complex way due to the probable competition of some phenomena (crosslinking and reaction vs reduction of crystallinity degree and H bond attenuation), with little effect over PVA morphology.
Air‐based polyethylene fragmentation with high yield to form microplastic particles as reference material candidates
Authors: Schmitt Marco , Altmann Korinna , Fengler Petra , Gehde Michael
Published: March 2023

Microplastic (MP) particles with sizes between 1 and 1000 µm are widely distributed worldwide. Origin, transport pathways, and fate are poorly known, as sampling, sample preparation, and detection methods are major challenges. In addition, reference materials that mimic environmental particles are lacking. The most challenging is the yield of MP particle production and the need for resource‐intensive grinding with liquid nitrogen. In this paper, a machine is designed to produce aged microplastic particles as reference material candidates with high yield. The machine is based on ultraviolet aging of a thin foil and mechanical fragmentation using clean air. An example of aging and fragmentation of high‐density polyethylene with additional physical and chemical characterization of shape, size, aging state by carbonyl index, and density is presented.
Graphene‐Encapsulated Nitrogen‐doped Carbon@Bi Enables Rapid, Ultrahigh and Durable Sodium Storage
Authors: Wang Meixue , Li Huijun , Cheng Xiaoqin , Tian Shizhen , Wang Xiaomin
Published: March 2023

Bismuth (Bi) has promising applications as anode in sodium‐ion batteries (SIBs) due to its suitable alloy voltage, unique lattice structure and high volumetric specific capacity. However, the severe structural degradation and poor cycling performance of Bi‐anode during cycling limits its practical application. Here, we designed and synthesized graphene‐encapsulated nitrogen‐doped carbon@bismuth (N−C@Bi/G) composites as anode materials for SIBs by a two‐step hydrothermal and thermal treatment method to solve the above problems. The N−C@Bi/G composite anode material exhibits excellent sodium storage performance, high capacity (280 mAh g−1 at 0.1 A g−1 and an initial coulombic efficiency of 78.87 %) and long‐term cycling stability (260 mAh g−1 after 1000 cycles at 2 A g−1). Electrochemical analysis and DFT calculations show that the fast reaction kinetics of N−C@Bi/G is directly related to the introduction of nitrogen‐doped carbon enriching the pore structure and increasing the active sites. Meanwhile, through the aid of in‐situ X‐ray diffraction (XRD), the reaction mechanism and interphase evolution of N−C@Bi/G composite are revealed, which provides an important theoretical basis for the application of SIBs.

Published: March 2023

Developing new electrode materials and/or electrolytes for lithium‐ion batteries requires reliable electrochemical testing thereof. For this purpose, in academic research typically hand‐made coin‐type cells are assembled. Their advantage is a rather cheap and facile assembly, and possibility to prepare full‐cells as well as half‐cells, meaning cathode‐anode or electrode‐elemental lithium configurations. Critical parameters for testing data quality and the potential and limitations of cell tests in half‐cell configuration are discussed. Further, on the basis of a round robin test, using highly homogenous commercial electrodes, where graphite is used as anode and LiNi0.33Mn0.33Co0.33O2 (NMC111) as the cathode material, it is shown that data acquired is highly influenced by assembling parameters. Besides known variables such as the amount of electrolyte or electrode positioning, the proper height of the cell stack and the steel grade of the housing material are identified as decisive variables. Finally, it is demonstrated that under proper conditions coin cells can show a great cycle stability of >2200 cycles using 1 C as dis‐/charge rate while retaining a capacity of 80 %. This performance is close to pouch‐type cells containing the same electrodes and electrolyte, which were used as a benchmark system and showed >3500 cycles of lifetime.
Simultaneous positive and negative selection of proteases in bacterium based on cell suicide and antibiotic resistance

Published: March 2023

Methods for engineering protease specificity and selectivity toward target substrates of therapeutic or industrial relevance are of wide interest. Herein, we report a bacterial system for the simultaneous detection and selection of protease activity on positive and negative target substrates. The system, based on Proteolysis‐triggered bActerial SuiCide and Antibiotic Resistance (PASCAR) in Escherichia coli, exploits the β‐lactamase and the human gasdermin D (GS) for the proteolysis‐responsive positive and negative selections, respectively. The applicability of the positive selection was illustrated with the directed evolution of the Tobacco etch virus protease toward the recognition of non‐native substrates. We also utilized the positive selection for the efficient evaluation of computationally redesigned protease variants. We constructed and optimized a series of GS mutants as suicide modules – with high to low selection stringencies – that would enable the use of PASCAR as a practically applicable dual selection system. This study provides a simple and easily accessible tool that facilitates the engineering of proteases with custom specificity and selectivity.

Insanity evaluations are often criticized for their—alleged—lack of objectivity, reliability and transparency. Structured tools to guide and support forensic evaluators during these evaluations have been developed—but they are rarely employed in forensic practice. In the present article, we consider the value of these tools for forensic practice in terms of opportunities and limitations. First, we briefly describe different insanity criteria used in Western countries. Next, we will review five structured instruments to guide insanity assessment together with their performance measures. Finally, we draw conclusions on the value of such instruments for forensic practice.

During stem cell therapy, some issues, such as obscure fate of stem cells or their low survival rate in the body, should be addressed to boost their therapeutic efficiency. Nanotechnology offers a suitable solution to combat such limitations. Carbon quantum dots (CQDs) are carbon‐based nanomaterials and may be used as multi‐purpose compounds in stem cell therapy. CQDs are excellent choices for stem cell labeling thanks to their special features such as optical properties and good biocompatibility. Besides, they can modulate the biological function of stem cells, such as their proliferation, homing ability, and differentiation properties. Considering the charismatic feature of CQDs and their broad unique effect on stem cells, the current review aims to summarize the most advancements in this field. Hence, we first focused on CQDs synthesis and their applications. In the next section, the stem cell categories will be discussed, and the final part is dedicated to the recent research evaluating the impact of CQDs on stem cell therapy.

Spatiotemporal modulation of microtubules by light has become an important aspect of the biological and nanotechnological applications of microtubules. We previously developed a Tau‐derived peptide as a binding unit to the inside of microtubules. Here, we conjugated the Tau‐derived peptide to spiropyran, which is reversibly converted to merocyanine by light, as a reversible photocontrol system to stabilize microtubules. Among the synthesized peptides with spiropyran/merocyanine at different positions, several peptides were bound to the inside of microtubules and stabilized the structures of microtubules. The peptide with spiropyran at the N‐terminus induced polymerization and stabilization of microtubules, whereas the same peptide with the merocyanine form did not exert these effects. Reversible formation of microtubules/tubulin aggregates was achieved using the peptide with spiropyran conjugated at the N‐terminus and irradiation with UV and visible light. Spiropyran‐conjugated Tau‐derived peptides would be useful for spatiotemporal modulation of microtubule stability through reversible photocontrol of binding.

Rosai‐Dorfman disease (RDD) is a proliferative disorder of histiocytes typically found in nodal sites and commonly observed in females. Patients often present with systemic symptoms such as fever, lymphadenopathy, and weight loss. However, extra‐nodal disease has been identified in locations including the skin and subcutaneous tissue. We present a case of a 59‐year‐old female presenting with abnormal bilateral findings on screening mammography, who was found to have a rare presentation of Rosai‐Dorfman disease.

Postprandial reactive hypoglycemia, or late dumping syndrome, is a common but underrecognized complication from bypass surgery. We report an unusual case of postprandial reactive hypoglycemia in a patient with a severe esophageal stricture from corrosive agent ingestion who underwent ileocolic interposition and an antecolic Billroth‐II gastrojejunostomy. A 22‐year‐old male patient with a one‐year history of corrosive ingestion was referred to the hospital for a surgical correction of severe esophageal stricture. After the patient underwent ileocolic interposition and an antecolic Billroth‐II gastrojejunostomy, he experienced multiple episodes of gastroesophageal refluxsymptoms during nasogastric feeding and had onset of hypoglycemic symptoms. His plasma glucose level was 59 mg/dL. After we had intraoperatively re‐inserted a jejunostomy tube bypassing the ileocolic interposition, and reintroduced enteral nutrition, his hypoglycemic symptoms resolved. We performed a mixed meal tolerance test by nasogastric tube, but the results did not show postprandial hypoglycemia. Although the specific mechanism is unclear, this case suggests gastroesophageal reflux to the ileal interposition may have caused a state of exaggerated hyperinsulinemic response and rebound hypoglycemia. To the best of our knowledge, we are the first to report case of postprandial hypoglycemia after ileocolic interposition, which may have been caused by exaggerated hyperinsulinemic response due to gastroesophageal reflux to the ileal interposition. This syndrome should be considered in the patient who has had ileocolic interposition surgery and has developed postprandial hypoglycemia.

The shortage of fresh water in the world has brought upon a serious crisis to human health and economic development. Solar‐driven interfacial photothermal conversion water evaporation including evaporating seawater, lake water, or river water has been recognized as an environmentally friendly process for obtaining clean water in a low‐cost way. However, water transport is restricted by itself by solar energy absorption capacity's limits, especially for finite evaporation rates and insufficient working life. Therefore, it is important to seek photothermal conversion materials that can efficiently absorb solar energy and reasonably design solar‐driven interfacial photothermal conversion water evaporation devices. This paper reviews the research progress of carbon‐based photothermal conversion materials and the mechanism for solar‐driven interfacial photothermal conversion water evaporation, as well as the summary of the design and development of the devices. Based on the research progress and achievements of photothermal conversion materials and devices in the fields of seawater desalination and photothermal electric energy generation in recent years, the challenges and opportunities faced by carbon‐based photothermal conversion materials and devices are discussed. The prospect of the practical application of solar‐driven interfacial photothermal conversion evaporation technology is foreseen, and theoretical guidance is provided for the further development of this technology.

Published: March 2023

Biomimetic synthesis of guanine crystals has been focused on in the last years. However, multi‐functional guanine crystals occluded with fluorescent molecules have not been realized in the laboratory. Here, the controllable synthesis of guanine crystal microplatelets with fluorescence and pearlescence was achieved for the first time by incorporating Nile red (NR) or fluorescein isothiocyanate (FITC) molecules into guanine crystals. The synthesized fluorescent guanine crystals are pure β‐phase anhydrous guanine single crystals. Aqueous suspensions with NR‐ and FITC‐doped guanine crystals exhibit distinct pearlescence. The fluorescence intensities of NR and FITC were greatly enhanced after being doped into guanine crystals due to the inhibition of aggregation‐caused quenching. Moreover, films composed of fluorescent guanine microplatelets exhibit high diffuse reflection intensity (70 %). This work provides a strategy to synthesize multifunctional materials composed of organic crystals occluded with dyes.

Chemical energy carriers produced according to power‐to‐X concepts will play a crucial role in the future energy system. Here, CO2 methanation is described as one promising route. However, transient operating conditions and the resulting effects on catalyst stability are to be considered. In this contribution, a tap reactor for spatially and temporally resolved analysis of the methanation reaction is presented. The Ni catalyst investigated was implemented as coating. Reaction data as a function of time and reactor coordinate under various operating conditions are presented and discussed. A comparison with simulation data validates the presented tap reactor concept.

Comprehensive Summary

Chemical functionalization of fullerenes has been an important topic in fullerene chemistry. Herein, an unprecedented Pd‐catalyzed migration reaction of [60]fullerene with allyloxy‐tethered aryl iodides is present for the preparation of novel [60]fullerene‐fused allylbenzofurans. The use of 1,2‐bis(diphenylphosphino)benzene (DPPBz) as a ligand is crucial for the success of the transformation. The reaction shows high chemo‐ and regioselectivity, and is flexible with regard to allyl‐migration site, providing a new and efficient approach to rare [60]fullerene‐fused benzofurans. Control experiments disclose that the reaction most probably undergoes a sequential C—O bond cleavage/allyl‐migration/intermolecular cycloaddition cascade process.

Published: March 2023

Organic–inorganic hybrid perovskites have attracted tremendous attention in the photovoltaic industry because of their low cost, simple production process, and high efficiency. However, (photo)stability is still one of the main problems that limits their development and enormous efforts have been made in this area. In this Review, we focus on the ubiquitous redox reactions in perovskite solar cells (PSCs), reveal the reasons behind the occurrence of the reactions (both external and internal factors) and the resulting effects (favorable and unfavorable), and collect methods to mitigate or block the occurrence of the reaction. Then, we summarize the means of characterizing redox reactions to visualize their presence and mechanisms. Finally, we envision future research directions in this field and consider redox reactions a double‐edged sword. We hope that these insights will contribute to accelerating the commercialization of PSCs.
