Returning is a paradox; even more so as an orientation to(wards) the seductive forces that we return (to) throughout this special Issue. One can return and never return all at once. Return is like a wave; it turns itself – returns that never return to how it was in the beginning. There is no clearly identifiable beginning; there is no end or ending. This introduction desires to do exactly that: to fold our academic-writing-matter in the mess and mass of such academic workings. Theory and theoretical contexts seduce us and we would like to share some forces of that seduction with you, our readers. And yet! We sit in this writing with the (im)possibilities in such desires for sharing. Seduction might not communicate itself, might not show its character and elements, and it might not even produce something tangible and sharable. In such absence, will seduction be at work then? Will diffractive forces of seduction be muted and decapitated? Might the seduced and seductive body of academic-writing-matter matter in its absence? This introduction will … [hmmm! This impulse to identify a neat start, an originary point, operates as a such a strong force]

Aim: To investigate the alteration of some sperm proteins, anti-oxidants, and prostate-specific antigen in the seminal plasma of bacteriospermic infertile males.
Study Design: The study is a case-control design to investigate the semen parameters and some sperm proteins in infertile males with bacteriospermia attending urology or fertility clinics in Port Harcourt, Rivers State, Nigeria.
Place and Duration of Study: The study was carried out in the Department of Medical Laboratory Science, Rivers State University, Port Harcourt. However, some of the Laboratory investigations were done in the Chemical Pathology Unit and Medical Microbiology Unit of the University of Port Harcourt Teaching Hospital, Port Harcourt. The Study was between the period of September 2019 and Feb. 2022.
Methodology: A total 193 subjects were recruited of which 76 were fertile without bacterial infection, 24 were fertile with bacterial infection, 37 infertile without bacterial infection and 56 infertile with bacterial infections. Infertile males were further classified as teratozoospermic, asthenoteratozoospermic, and oligoasthenoteratozoospermic. HSP70, PKA, MDA, TAC, and GPX (in seminal plasma), PSA, and testosterone (in serum) were analyzed using ELISA while TAC was done using spectrophotometric methods. Microbial culture was done to isolate and identify bacteria in semen. Results obtained were analyzed using GraphPad Prism and SPSS.
Results: Culture results indicated that 52% of normospermic subjects had no semen infection at the time of the investigation. On the other hand, infertile male subjects without semen infections had 18.7%, while infertile males with semen infections were seen to be 29.2%. Likewise, subjects with bacteriospermia as scanty growth had 12.5%, 9.3% moderate, and 7.3% heavy growth. Significantly higher values of HSP70, PKA, PSA, and MDA were seen in infertile males with bacteriospermia compared with control and infertile males without infection while significantly lower values were seen in TAC, GPX, OPN, and testosterone were observed in the infertile males with bacteriospermia compared with control and infertile males without infection.
Conclusion: Bacteriospermia significantly increased lipid peroxidation cum oxidative stress leading to altered physiological sperm proteins in the seminal plasma. These alterations could also be responsible for the poor sperm qualities observed in the infertile subjects.

AbstractObjectiveTo assess the initial features and evolution of neurologic Postacute Sequelae of SARS‐CoV‐2 infection (neuro‐PASC) in patients with and without prior neurologic disease.MethodsParticipants with neurologic symptoms following acute SARS‐CoV‐2 infection were recruited from October 9, 2020 to October 11, 2021. Clinical data included a SARS‐CoV‐2 infection history, neurologic review of systems, neurologic exam, Montreal cognitive assessment (MoCA), and symptom‐based self‐reported surveys at baseline (conducted after acute infection) and 6‐month follow‐up assessments.ResultsFifty‐six participants (69% female, mean age 50 years, 29% with prior neurologic disease such as multiple sclerosis) were enrolled, of which 27 had completed the 6‐month follow‐up visit in this ongoing study. SARS‐CoV‐2 infection severity was largely described as mild (39.3%) or moderate (42.9%). At baseline, following acute infection, the most common neurologic symptoms were fatigue (89.3%) and headaches (80.4%). At the 6‐month follow‐up, memory impairment (68.8%) and decreased concentration (61.5%) were the most prevalent, though on average all symptoms showed a reduction in reported severity score at the follow‐up. Complete symptom resolution was reported in 33.3% of participants by 6 months. From baseline to 6 months, average MoCA scores improved overall though 26.3% of participants’ scores decreased. A syndrome consisting of tremor, ataxia, and cognitive dysfunction (PASC‐TAC) was observed in 7.1% of patients.InterpretationEarly in the neuro‐PASC syndrome, fatigue and headache are the most commonly reported symptoms. At 6 months, memory impairment and decreased concentration were most prominent. Only one‐third of participants had completed resolution of neuro‐PASC at 6 months, although persistent symptoms trended toward improvement at follow‐up.

AbstractProtein crystallization remains a major bottleneck for the determination of high resolution structures. Nucleants can accelerate the process but should ideally be compatible with high throughput robotic screening. Polyethylene glycol grafted (PEGylated) graphenes can be stabilized in water providing dispensable, nucleant systems. Two graphitic feedstocks are exfoliated and functionalized with PEG using a non‐destructive, scalable, chemical reduction method, delivering good water dispersibility (80 and 750 µg mL−1 for large and small layers, respectively). The wide utility of these nucleants has been established across five proteins and three different screens, each of 96 conditions, demonstrating greater effectiveness of the dispersed PEGylated graphenes. Smaller numbers of larger, more crystalline flakes consistently act as better protein nucleants. The delivered nucleant concentration is optimized (0.1 mg mL−1 in the condition), and the performance benchmarked against existing state of the art, molecularly imprinted polymer nucleants. Strikingly, graphene nucleants are effective even when decreasing both the nucleant and protein concentration to unusually low concentrations. The set‐up to scale‐up nucleant production to liter volumes can provide sufficient material for wide implementation. Together with the optimized crystallization conditions, the results are a step forward toward practical synthesis of a readily accessible “universal” nucleant.

AbstractHere, a comprehensive study on the synthesis, characterization, and reactivity of grain‐boundary (GB)‐rich noble metal nanoparticle (NP) assemblies is presented. A facile and scalable synthesis of Pt, Pd, Au, Ag, and Rh NP assemblies is developed, in which NPs are predominantly connected via Σ3 (111) twin GBs, forming a network. Driven by water electrolysis, the random collisions and oriented attachment of colloidal NPs in solution lead to the formation of Σ3 (111) twin boundaries and some highly mismatched GBs. This synthetic method also provides convenient control over the GB density without altering the crystallite size or GB type by varying the NP collision frequency. The structural characterization reveals the presence of localized tensile strain at the GB sites. The ultrahigh activity of GB‐rich Pt NP assembly toward catalytic hydrogen oxidation in air is demonstrated, enabling room‐temperature catalytic hydrogen sensing for the first time. Finally, density functional theory calculations reveal that the strained Σ3(111) twin boundary facilitates oxygen dissociation, drastically enhancing the hydrogen oxidation rate via the dissociative pathway. This reported large‐scale synthesis of the Σ3 (111) twin GB‐rich structures enables the development of a broad range of high‐performance GB‐rich catalysts.

AbstractMetal patterning via additive manufacturing has been phasing‐in to broad applications in many medical, electronics, aerospace, and automotive industries. While previous efforts have produced various promising metal‐patterning strategies, their complexity and high cost have limited their practical application in rapid production and prototyping. Herein, a one‐step gold printing technique based on anion‐assisted photochemical deposition (APD), which can directly print highly conductive gold patterns (1.08 × 107 S m−1) under ambient conditions without post‐annealing treatment, is introduced. Uniquely, the APD uses specific ion effects with projection lithography to pattern Au nanoparticles and simultaneously sinter them into tunable porous gold structures. The significant influence of kosmotropic or chaotropic anions in the precursor ink on tuning the morphologies and conductivities of the printed patterns by employing a series of different ions, including Cl− ions, in the printing process is presented. Additionally, the resistance stabilities and the electrochemical properties of the APD‐printed gold patterns are carefully investigated. The high conductivity and excellent conformability of the printed Au electrodes are demonstrated with reliable performance in electrophysiological signal delivery and acquisition for biomedical applications. This work exploits the potential of photochemical‐deposition‐based metal patterning in flexible electronic manufacturing.

Published: June 2022

AbstractBlends of nanoparticles, polymers, and small molecules can self‐assemble into optical, magnetic, and electronic devices with structure‐dependent properties. However, the relationship between a multicomponent nanocomposite's formulation and its assembled structure is complex and cannot be predicted by theory. The blends can be strongly influenced by processing conditions, which can introduce non‐equilibrium states. Currently, nanocomposite devices are designed through cycles of experimental trial and error. Machine learning (ML) methods are a compelling alternative because they can use existing datasets to map high‐dimensional spaces. These methods do not rely on known relationships between parameters, so they are suited to complex systems without a solid theoretical foundation. Here, a dataset of 595 microscopy images of nanocomposite thin films is used to train a series of ML models. Correlations between the input and output parameters are examined, providing new insights into the system. Finally, the most successful ML model is used to predict the structures of new nanocomposite compositions. The results confirm that ML techniques can be used to improve the efficiency of nanocomposite device design. More broadly, the current study suggests some of the advantages and challenges associated with applying ML to complex systems.

Published: June 2022

AbstractStretchable strain sensors are highly desirable for human motion monitoring, and can be used to build new forms of bionic robots. However, the current use of flexible strain gauges is hindered by the need for an external power supply, and the demand for long‐term operation. Here, a new flexible self‐powered strain sensor system based on an electromagnetic generator that possesses a high stretchability in excess of 150%, a short response time of 30 ms, and an excellent linearity (R2 > 0.98), is presented. Based on this new form of sensor, a human–machine interaction system is designed to achieve remote control of a robot hand and vehicle using a human hand, which provides a new scheme for real‐time gesture interaction.
Heteroatom Modification Enhances Corrosion Durability in High‐Mechanical‐Performance Graphene‐Reinforced Aluminum Matrix Composites

Published: June 2022

AbstractThe antagonism between strength and corrosion resistance in graphene‐reinforced aluminum matrix composites is an inherent challenge to designing reliable structural components. Heteroatom microstructural modification is highly appreciated to conquer the obstacle. Here, a bottom‐up strategy to exploit the heterogeneous phase interface to enable high corrosion durability is proposed. Deformation‐driven metallurgy derived from severe plastic deformation is developed to produce Mg‐alloyed fluorinated graphene structures with homogeneous dispersion. These structures allow for absorbing corrosion products, forming a dense protective layer against corrosion, and local micro‐tuning of the suppression of charge transfer. This results in superior corrosion resistance with an outstanding strength‐ductility balance of the composites via ultrafine‐grained and precipitation strengthening. The anti‐corrosion polarization resistance remains 89% of the initial state after 2‐month immersion in chloride‐containing environment, while the ultra‐tensile strength and elongation of 532 ± 39 MPa and 17.3 ± 1.2% are obtained. The economical strategy of heteroatom modification broadens the horizon for anti‐corrosion engineering in aluminum matrix composites, which is critical for the design of carbonaceous nanomaterial‐reinforced composites to realize desired performances for practical applications.

Published: June 2022

AbstractPhoto‐electrochemical production of solar fuels from carbon dioxide, water, and sunlight is an appealing approach. Nevertheless, it remains challenging to scale despite encouraging demonstrations at low power input. Higher current densities require notable voltage input as ohmic losses and activation overpotentials become more significant, resulting in lower solar‐to‐CO conversion efficiencies. A concentrated photovoltaic cell is integrated into a custom‐made heat managed photo‐electrochemical device. The heat is transferred from the photovoltaic module to the zero‐gap electrolyzer cell by the stream of anodic reactant and produce synergetic effects on both sides. With solar concentrations up to 450 suns (i.e., 450 kW m−2) applied for the first time to photo‐electrochemical reduction of CO2, a partial current for CO production of 4 A is achieved. At optimal conditions, the solar‐to‐CO conversion efficiency reaches 17% while maintaining a current density of 150 mA cm−2 in the electrolyzer and a CO selectivity above 90%, representing an overall 19% solar‐to‐fuel conversion efficiency. This study represents a first demonstration of photo‐electrochemical CO2 reduction under highly concentrated light, paving the way for resource efficient solar fuel production at high power input.
Preventing households from food insecurity in rural Burkina Faso: Does nonfarm income matter?
Authors: Séogo Windinkonté 
Published: June 2022

AbstractEngaging in nonfarm activities has been considered an important strategy to increase household income in rural Burkina Faso. However, the empirical evidence on how income from nonfarm activities contributes to household food security in the country is limited. Relying on nationwide household panel data and an instrumental variable approach, this study shows that income from nonfarm activities positively affects household food stability and overall food expenditure. The share of food expenditure is also found to be negatively associated with income from nonfarm activities, suggesting an improvement in households' economic status. This evidence has crucial policy implications for food security in rural Burkina Faso, where households face severe income shocks due to both climatic variability and poor investments in agriculture.

AbstractA significant body of research has demonstrated that mentoring relationships support positive youth development. The quality of the mentoring relationship has been identified as a predictor of positive youth outcomes. However, limited research has examined how engagement in a mentoring program may be related to youth depressive symptoms specifically. The current study utilized a sample of 2003 youth participating in mentoring programs across the country (Mage = 12.32, SD = 1.42, 55.1% female) from diverse racial and ethnic backgrounds (39.1% Black, 23.6% White, 22.1% Hispanic, 3.3% Native American or Alaskan Native, .4% Asian or Pacific Islander, 1.8% other, and 9.7% Multi‐Ethnic) to investigate associations between youth depressive symptoms and mentoring relationship quality. Results revealed that: (1) mean depressive symptoms decreased after participation in a mentoring program; (2) several, but not all, relationship quality indicators predicted change in depressive symptoms; (3) baseline levels of depressive symptoms negatively predicted indicators of relationship quality; and (4) associations between several relationship quality indicators and follow‐up depressive symptoms differed by baseline levels of depressive symptoms. These findings highlight the potential benefits of mentoring programs to youth and the need to provide mentors with support around building relationships with youth, especially those experiencing depressive symptoms.

Published: June 2022

AbstractBispecific T cell engagers (TCE) derive from monoclonal antibodies and concomitantly engage a target on the surface of cancer cell and CD3 on the surface of T‐cells. TCEs promote T cell activation and lysis of tumor cells. Most TCEs in development for multiple myeloma (MM) target the B cell maturation antigen (BCMA) and differ among themselves in structure, pharmacokinetics, route and schedule of administration. CD3/BCMA TCEs produce response in ~60% of patients treated in phase 1 trials. TCEs are also in development targeting the G protein‐coupled receptor, class C group 5 member D (GPRC5D) and the Fc receptor homologue 5 (FcRH5). Main toxicities are cytokine release syndrome and cytopenias. Here we review the current development and future directions of TCEs in MM.
