Authors: Solomon Enyidah Nonyenim , Ijeoma Nonye-Enyidah Esther 
Published: December 2022

Background: Postnatal depression is one of the most devastating of the mental disorders affecting women six weeks postpartum, accounting for more than 20% of maternal deaths after childbirth. It is said that young children of mothers with postnatal depression have greater behavioural problems than those of non- depressed mothers. Mode of delivery with other risk factors has been implicated as a predictive factor and caesarean section in any form is said to be most implicated. This study intends to contribute to the raging arguments on the relationship between caesarean section and postnatal depression.
Objective: To examine the relationship between caesarean sections and postnatal depression.
Methods: Women visiting the postnatal clinic six weeks postpartum who consented to the study, where interviewed and screened for depression using the study designed questionnaire and the Edinburg postnatal depressive scale (EPDS). Data obtained were analysed using the statistical package for social sciences (SPSS) version 23.0, p values <0.05 were statistically significant.
Results: Out of 405 women who participated in the study, 135 (33.3%) had an EPDS score of > 12 points. Among the risk factors isolated which included co-habiting, death of children, children challenges and partner violence, caesarean section showed a very strong association p=0.001, OR 1.68, 95% cl=1.10-2.58. Emergency caesarean section showed a stronger association p=0.001, OR 3.6, 95%cl=2.35-5.69.
Conclusion: Emergency caesarean section has a strong significant impact on the development of postnatal depression.

AbstractThe paradigm shift of information carriers from charge to spin has long been awaited in modern electronics. The invention of the spin‐information transistor is expected to be an essential building block for the future development of spintronics. Here, a proof‐of‐concept experiment of a magnetic skyrmion transistor working at room temperature, which has never been demonstrated experimentally, is introduced. With the spatially uniform control of magnetic anisotropy, the shape and topology of a skyrmion when passing the controlled area can be maintained. The findings will open a new route toward the design and realization of skyrmion‐based spintronic devices in the near future.
Boosting Energy Transfer from Self‐Trapped Exciton to Er3+ Through Sb3+ Doping in Cs2Na(Lu/Er)Cl6 Double Perovskites

Published: December 2022

AbstractMetal halide double perovskites are highly attractive for optoelectronic applications because of their superior optical properties. Here, a novel halide double perovskite, Cs2NaLuCl6, exhibiting bright blue emission originating from the host self‐trapped exciton (STE) is reported. Through doping with Sb3+, the dopant‐induced STE is formed in the crystals with a photoluminescence quantum yield up to 94%. The energy transfer from the dopant STE to Er3+ is superior to the direct excitation of Er3+, which is more efficient than the energy transfer from the host STE to Er3+. Furthermore, the energy transfer efficiency from STE to Er3+ is boosted from 8% to 33% through Sb3+ doping in Cs2NaLu0.95Er0.05Cl6. Due to the strong electron‐phonon coupling and efficient energy transfer, the as‐prepared crystals exhibit intense dual‐band emissions and remarkable thermal stability. Importantly, the STE emission variation after the Er3+‐substitution is explored based on the electron‐phonon coupling effect. These findings provide new insights into the excited state dynamics of halide double perovskites and extend their luminescence applications such as white light‐emitting diodes and night vision.

Published: December 2022

AbstractA Lewis acid catalyzed carbofunctionalization of styrenes with diacyl peroxides and nucleophiles, including amines, indoles, trimethoxybenzenes, and carboxylic acid, has been accomplished. A wide range of primary, secondary, and tertiary alkyl diacyl peroxides generated from inexpensive aliphatic acids serve as both simple alkylating reagents and internal oxidants for the synthesis of value‐added amines, indoles, 1,1‐diarylalkanes, and esters in moderate to good yields. This protocol features site selectivity, broad substrate scope, and mild reaction conditions.magnified image

Published: December 2022

AbstractMetal zinc is recognized as a promising anode candidate for aqueous zinc‐ion batteries (AZIBs), however, dendrites and byproducts formation severe deteriorate its reversibility and practical lifespan. Herein, a polydopamine (PDA) layer, which offers the dual effects of fast desolvation and ion confinement, is constructed on the surface of a Zn anode for efficient AZIBs. The abundant polar functional groups in PDA significantly enhance interfacial contact in aqueous media, which reduces the number of water molecules reaching the zinc surface through fast desolvation, thus lowering the energy barrier for Zn2+ migration. Furthermore, the porous PDA coating controls the ion flux via the ion‐confinement effect, thereby accelerating Zn2+ kinetics on the zinc surface. Consequently, Zn@PDA exhibits significantly improved Zn2+ deposition kinetics (nucleation potential of only 32.6 mV vs 50.2 mV of bare Zn) compared with bare Zn at 2.0 mA cm−2, with a dendrite‐free surface and negligible byproduct formation. When paired with a MnO2 cathode, the Zn@PDA//MnO2 cell delivers high discharge capacity and long cycle stability without significant performance deterioration over 1000 cycles at 1.0 A g−1. Additionally, the cell demonstrates excellent shelving‐restoring performance.

Published: December 2022

ObjectiveSmall‐fiber neuropathy (SFN) is characterized by neuropathic pain due to degeneration of small‐diameter nerves in the skin. Given that brain reorganization occurs following chronic neuropathic pain, this study investigated the structural and functional basis of pain‐related brain changes after skin nerve degeneration.MethodsDiffusion‐weighted and resting‐state functional MRI data were acquired from 53 pathologically confirmed SFN patients, and the structural and functional connectivity of the pain‐related network was assessed using network‐based statistic (NBS) analysis.ResultsCompared with age‐ and sex‐matched controls, the SFN patients exhibited a robust and global reduction of functional connectivity, mainly across the limbic and somatosensory systems. Furthermore, lower functional connectivity was associated with skin nerve degeneration measured by reduced intraepidermal nerve fiber density and better therapeutic response to anti‐neuralgia medications, particularly for the connectivity between the insula and the limbic areas including the anterior and middle cingulate cortices. Similar to the patterns of functional connectivity changes, the structural connectivity was robustly reduced among the limbic and somatosensory areas, and the cognition‐integration areas including the inferior parietal lobule. There was shared reduction of structural and functional connectivity among the limbic, somatosensory, striatal, and cognition‐integration systems: (1) between the middle cingulate cortex and inferior parietal lobule and (2) between the thalamus and putamen. These observations indicate the structural basis underlying altered functional connectivity in SFN.InterpretationOur findings provide imaging evidence linking structural and functional brain dysconnectivity to sensory deafferentation caused by peripheral nerve degeneration and therapeutic responses for neuropathic pain in SFN.

One‐Step In Situ Polymerization: A Facile Design Strategy for Block Copolymer Electrolytes
Authors: Guo Kairui , Wang Jirong , Shi Zhen , Wang Yong , Xie Xiaolin , Xue Zhigang 
Published: December 2022

AbstractTo optimize the rapid transport of lithium ions (Li+) inside lithium metal batteries (LMBs), block copolymer electrolytes (BCPEs) have been fabricated in situ in LMBs via a one‐step method combining reversible addition‐fragmentation chain transfer (RAFT) polymerization and carboxylic acid‐catalyzed ring‐opening polymerization (ROP). The BCPEs balanced the Li+ coordination characteristics of the polyether‐ and polyester‐based electrolytes to achieve a rapid Li+ migration in the SPEs. The carboxylic acid played a dual role since it both catalyzed the ROP and stabilized the interface. Furthermore, the in situ assembly of LMBs did effectively enable an efficient intercalation/de‐intercalation of Li+ at the electrode/electrolyte interface. The in situ assembled Li/BCPE4/LFP exhibited high‐capacity retention of 92 % after 400 cycles at 1 C. The one‐step in situ fabrication of BCPEs provides a new direction for the design of polymer electrolytes.

Published: December 2022

AbstractAs a conjugated and unsymmetric building block composed of an electron‐poor seven‐membered sp2 carbon ring and an electron‐rich five‐membered carbon ring, azulene and its derivatives have been recognized as one of the most promising building blocks for novel electronic devices due to its intrinsic redox activity. By using 1,3,5‐tris(4‐aminophenyl)‐benzene and azulene‐1,3‐dicarbaldehyde as the starting materials, an azulene(Azu)‐based 2D conjugated covalent organic framework, COF‐Azu, is prepared through liquid‐liquid interface polymerization strategy for the first time. The as‐fabricated Al/COF‐Azu/indium tin oxide (ITO) memristor shows typical non‐volatile resistive switching performance due to the electric filed induced intramolecular charge transfer effect. Associated with the unique memristive performance, a simple convolutional neural network is built for image recognition. After 8 epochs of training, image recognition accuracy of 80 % for a neutral network trained on a larger data set is achieved.

Authors: Monika Sankar , Ramesh Rengan 
Published: December 2022

A simple, straightforward and atom economic strategy to the synthesis of 1,3‐disubstituted imidazo[1,5‐a]pyridines using binuclear ruthenium(II) catalyst through acceptorless dehydrogenative coupling of primary alcohols with 2‐benzoylpyridine has been presented. New binuclear arene Ru(II) N^O chelating complexes of common formula [(η6‐benzene)2Ru2Cl2(μ‐L)], L = bis (furoylhydrazone) derivatives (1–3) were synthesized and characterized by analytical and spectral (FT‐IR, NMR and HR‐MS) techniques. The solid‐state molecular structure of one of the complexes (complex 1) has been authorized by single‐crystal XRD method. Further, a wide range of 1,3‐disubstituted imidazo[1,5‐a]pyridine derivatives have been successfully attained in good to excellent yields using binuclear arene Ru(II) catalysts with 1.0 mol% of catalyst loading. Further, control experiments unveil that the dehydrogenative coupling reaction mechanism proceeds via the formation of aldehyde and imine intermediates. The overall catalytic system releases H2 and water as only valuable by‐products.

ObjectiveTo examine whether the cross‐sectional gene–diet interaction for prevalent hyperuricemia among women translates prospectively to risk of incident female gout.MethodsWe analyzed the interaction between genetic predisposition and adherence to a healthy dietary pattern (i.e., Dietary Approaches to Stop Hypertension [DASH] score) on risk of incident female gout in 18,244 women from Nurses’ Health Study (NHS; discovery) and 136,786 women from 3 additional prospective female cohorts from the US and UK (replication). Genetic risk score (GRS) was calculated from 114 urate‐associated loci.ResultsIn the NHS and replication cohorts, association between diet and gout risk was larger and stronger among women with higher genetic risk. In all cohorts combined, compared to women with an unhealthy DASH score (less than the mean score), multivariable relative risk (RR) for incident gout among women with a healthy DASH score (greater than/equal to the mean score) was 0.67 (95% confidence interval [95% CI] 0.60–0.76) among higher GRS (greater than/equal to the mean score) and 0.91 (0.78–1.05) among lower GRS (P for multiplicative interaction = 0.001); multivariable RR for higher versus lower GRS was 2.03 (95% CI 1.80–2.29) and 1.50 (95% CI 1.31–1.71) among unhealthy and healthy DASH score groups, respectively. Additive interaction was also significant, in both the discovery and replication cohorts (P < 0.001), with 51% of the excess risk attributable to the additive gene–diet interaction in all cohorts combined.ConclusionThe deleterious effect of genetic predisposition on risk of incident female gout was more pronounced among women with unhealthy diets, with nearly half the excess risk attributable to this gene–diet interaction. These data elucidate the important synergy of genetics and diet for female gout development.

Published: December 2022

AbstractPoststent restenosis is caused by insufficient endothelialization and is one of the most serious clinical complications of stenting. We observed a rapid endothelialization rate and increased fibrin deposition on the surfaces of the corroded iron stents. Thus, we hypothesized that corroded iron stents would promote endothelialization by increasing fibrin deposition on rough surfaces. To verify this hypothesis, we conducted an arteriovenous shunt experiment to analyze fibrin deposition in the corroded iron stents. We implanted a corroded iron stent in both the carotid and iliac artery bifurcations to elucidate the effects of fibrin deposition on endothelialization. Co‐culture experiments were conducted under dynamic flow conditions to explore the relationship between fibrin deposition and rapid endothelialization. Our findings indicate that, from the generation of corrosion pits, the surface of the corroded iron stent was rough, and numerous fibrils were deposited in the corroded iron stent. Fibrin deposition in corroded iron stents facilitates endothelial cell adhesion and proliferation, which, in turn, promotes endothelialization after stenting. Our study is the first to elucidate the role of iron stent corrosion in endothelialization, pointing to a new direction for preventing clinical complications caused by insufficient endothelialization.

Published: December 2022

AbstractWater treatment is one of the main approaches for producing drinking water from contaminated water sources which is challenging due to the presence of a variety of substances requiring removal. The fabrication of nanocomposite membranes relies either on filling nanomaterials into polymeric phases before membrane fabrication, or coating of nanomaterials on the fabricated membrane surface. The removal of organic compounds from potable waters requires processes such as microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. Since most nanomaterials display interesting organic compound uptakes from aqueous systems, nanocomposite membranes have been tested in the removal of various substances from potable waters. Currently, many membrane processes necessitate more advanced and well‐designed selective barriers that may guarantee both permeation and separation efficiency. The progresses and breakthroughs on nanocomposite membranes in remediating potable waters are reported, highlighting novel composite formulations and emphasizing recent advances and outcomes in the field.

AbstractThe angiotensin‐converting enzyme (ACE) has been shown to play a role as a receptor for the COVID‐19 virus. This virus usually gets into cells and infects them by attaching to their glycoprotein receptors, which are found on the ACE2 receptor. The aim of this study was to evaluate the frequency and inheritance of ACE1 I/D and ACE2 rs2285666 polymorphisms in COVID‐19 patients with varying severity of lung involvement and its effect on serum cytokines levels of interleukin (IL)‐1 and IL‐6 and laboratory parameters. One hundred eighty‐five COVID‐19 patients were grouped according to the severity of lung involvement. (I/D) polymorphism of the ACE1 gene and rs2285666 polymorphism of the ACE2 gene were determined by single specific primer‐polymerase chain reaction and restriction fragment length reaction‐polymerase chain reaction methods, respectively. Serum levels of IL‐1 and IL‐6 were also measured by the enzyme linked immunosorbent assay technique. No statistically significant association of ACE2 rs2285666 polymorphism genotypes and ACE1 I/D with the severity of lung involvement was noted. However, there was a statistically significant association between I/D ACE1 polymorphism genotypes and IL‐6, white blood cells (WBC), and neutrophil‐to‐lymphocyte ratio (NLR) levels. Also, there was no statistically significant association between rs2285666 polymorphism genotypes and patients' blood oxygen saturation level, IL‐6, IL‐1β, lactate dehydrogenase activity, WBC count, and NLR. In patients with COVID‐19, the rs2285666 polymorphism of the ACE2 gene and the I/D polymorphism of the ACE1 gene were not significantly associated with the severity of COVID‐19 disease and serum IL‐6 and IL‐1 cytokine levels.

Authors: Cankurtaran Kömürcü Tekmile 
Published: December 2022

AbstractBackground and ObjectivesGevrek is grissini/breadstick like snack product. In this study, whole flours of modern wheat (Esperia), ancient wheats (einkorn, emmer, and spelt) and pseudocereal (amaranth, buckwheat, and quinoa) were used in gevrek formulation instead of refined wheat flour, and the effects on the physical, nutritional, and functional properties of gevreks were researched.FindingsThe use of pseudocereals in the gevrek formulation decreased the lightness and yellowness value compared to the control and ancient wheat gevreks. Also, pseudocereals especially buckwheat decreased the hardness of gevreks significantly (p < .05). The phytic acid content of Esperia and buckwheat gevrek were 50.98% and 51.21% less than amaranth gevreks, respectively. The use of buckwheat and emmer contributed greatly to the increase in total phenolic content as well as antioxidant activity. Amaranth gevrek was superior in terms of Ca, Fe, and Mg content among all gevrek samples. Esperia and emmer gevreks were the most liked by the panelists when all parameters were taken into account.ConclusionsThe use of ancient wheats and pseudocereals in the gevrek formulation yielded products with improved protein, antioxidant activity and phenolic content, acceptable technological quality and distinctive sensory properties.Significance and NoveltyCompared to traditional gevrek, our findings were the first to show that it is possible to produce nutritionally superior ancient wheat and pseudocereal‐enriched functional snacks (gevrek).

Published: December 2022

AbstractBurkitt lymphoma (BL) is a highly aggressive non‐Hodgkin B‐cell lymphoma. It has a doubling time of 24 h. Fortunately, it is highly sensitive to aggressive chemotherapy. Sporadic BL often affects the mesenteric and retroperitoneal lymph nodes. Extra‐nodal involvement includes the ileocecal area, stomach, kidneys, gonads, and central nervous system. Peritoneal lymphomatosis is a rare presentation. We report a case of BL presenting with peritoneal lymphomatosis to emphasize the importance of early histological diagnosis of any peritoneal thickening.

Published: December 2022

AbstractIn this study, the spectral and electrochemical properties of three newly synthesized stilbazolium dyes possessing an enlarged π‐conjugated system were examined. The synthesis of the dyes was carried by Knoevenagel condensation of 1‐butyl‐4‐methylquinolinium bromide as a common acceptor moiety precursor and different donor moiety precursors (2‐hydroxy‐naphtaldehyde or 4‐hydroxy‐naphtaldehyde or 4‐N, N‐dimethylamino naphthaldehyde). The composition of the produced compounds was confirmed by 1H‐ and 13C nuclear magnetic resonance (NMR) spectroscopy, elemental analysis, and infrared (IR)‐spectroscopy. Their properties including the solvatochromism in different solvents were investigated by ultraviolet‐visible (UV‐Vis) and fluorescence spectroscopy. The electrochemical properties of the dyes’ solutions in methanol were explored by cyclic voltammetry (CV), differential pulse voltammetry (DPV), and electrochemical impedance spectroscopy (EIS). The optical band‐gap values as well as the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy levels of the dyes were estimated based on experimental data and compared. A putative mechanism of electrochemical oxidation/reduction of the investigated dyes was also proposed.
