AbstractThe adsorption of particles on cotton affects its performance. Investigating the factors that affect particle adsorption on cotton can provide valuable insights into the adsorption process. By characterizing morphology, composition, structure, surface energy, and specific surface area, this study explores the adsorption of poly (butyl methacrylate) (PBMA) nanocapsules (NCs) on cotton via impregnation, including a preliminary study on the effect of concentration on adsorption. The results yield the following conclusions: (i) the viscosity of the PBMA emulsion increases with concentration, resulting in heightened particle adsorption on cotton and a thicker film after drying; (ii) the acidity and heat resistance of the cotton increase, owing to the formation of hydrogen bonds between the hydroxyl groups in PBMA and cotton and the increased hydrogen bonding interactions with adsorption; (iii) although the adsorption of PBMA NCs on cotton fibers causes a slight decrease in crystallinity and crystal plane spacing, the cotton retains impressive hydrophilicity, wettability, air permeability, and a porous structure. Based on these results, the study proposes a novel approach for the development of functional textiles.

Published: August 2021

AbstractBiocomposite materials (BMs) containing blends of synthetic polymers and biopolymers are made with the aim of enhancing the best characteristics of each material. In this work, polylactic acid (PLA) and high‐density polyethylene (HDPE) with maleic anhydride‐grafted polyethylene (PE‐g‐MA) blends were reinforced with banana fiber (BF). A simplex lattice mixture design {3,3} was selected to optimize the processing conditions and mechanical properties of the BMs. Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM) were used to analyze intermolecular interactions, grafting, miscibility, thermal properties and morphology. The optimal BM composition was 37.95 wt% BF and 30/32.05 wt% PLA/HDPE, which exhibited a stabilization time of 2.29 min, a tensile strength of 27.74 MPa and a ductility of 5.26%. The FTIR bands showed that the PE‐g‐MA compatibilizer interacted with the polar BF surface. The BM morphology showed ductile fracture with the absence of BF pull‐outs, consistent with the high tensile strength.

Abstract

Freshwater ecosystems, providing valuable goods and services to humans, have been subjected to multiple human impacts, among which climate change plays a central role in threats to species. It is expected that protected areas, the cornerstone of biodiversity conservation efforts, will assume a decisive role in protecting freshwater species from the impacts of climate change.
This study assessed the effects of climate change on migratory fish of the second largest neotropical river basin, evaluating the effectiveness of protected areas in safeguarding fish species, and hence the ecological functions that they perform and the ecosystem resources that they provide. The present range of 23 migratory fish of economic interest in the Paraná–Paraguay basin was estimated and the responses to future climatic shifts projected to the middle and end of the 21st century were examined, quantifying predictive uncertainties.
Changes and losses of climatically suitable areas will trigger severe contractions in range, with the greatest impact on the most valuable species in commercial fishing, where range losses are likely to surpass 65% in the future. The main channel of the Upper Paraná River and tributaries of its left margin are projected to serve as climatic refuges for many species, and such regions are not affected by high predictive uncertainty. The results revealed that protected areas do not sufficiently protect migratory fish at present, and that they will continue to offer negligible protection in the face of climate change.
This study alerts decision makers to the potential damage to inland fishery resources from climate change and provides useful information to guide conservation strategies spatially. We advocate that the creation of new protected areas and the redesign of the existing network to encompass regions that maximize current and future occupancy of migratory fish are crucial to conserve the valuable ecological, societal, and economic benefits that they provide.
Is the protected Atlantic cod (Gadus morhua) population in Gilbert Bay, Labrador, nearing a tipping point?
Authors: Morris Corey J. , Green John M. 
Published: August 2021

Abstract

The Gilbert Bay Marine Protected Area (MPA), Labrador, was created in 2005 to protect a resident, locally adapted population of Atlantic cod and its habitat. Twenty years of monitoring has shown a 90% decline in this bay‐cod population since the creation of the MPA.
The decline of large commercial‐sized cod in the bay was accompanied with increases in the abundance of other fish species, including rock cod (Gadus macrocephalus ogac), sculpin (Myoxocephlalus scorpius), and winter flounder (Pseudopleuronectes americanus), suggesting loss of strong top‐down community control.
These changes suggest a positive feedback mechanism leading to a fish community tipping point, which could severely impact the recovery potential of the protected Atlantic cod population in the MPA.
We suggest that managers should be including this possibility in their management decisions for the Gilbert Bay MPA.

AbstractBilirubin encephalopathy (BE) is a neurological syndrome in newborns, mainly caused by neuronal injury due to excessive oxidative stress produced by unconjugated bilirubin (UCB). Neuroglobin (NGB) can protect the brain by removing oxidative stress species, but its expression and significance in BE are not clear. To address this question, the neonatal BE model was established by injecting UCB into the cerebellomedullary cistern of 7‐day‐old SD rats. Rats were divided into a sham and BE 6 hr group, BE 12 hr group, BE 24 hr group, and BE 7 d group according to UCB action times. Hematoxylin/eosin and Nissl staining, and electron microscopy were employed to observe the pathological and ultrastructural changes of nerve cells in each group. Immunofluorescence staining was used to detect NGB expression sites and cell types. Western blotting and quantitative PCR served to detect NGB expression and test the mitochondrial apoptosis signal pathway. The results confirm that UCB can lead to pathological damage and ultrastructural changes in rats' temporal cortex, increasing the expression of apoptosis‐related proteins Bax, Bcl‐2, Cyt c, Caspase‐3, and neuronal NGB. UCB promotes NGB expression with an increase in action time and reach a peak at 12 hr. In summary, brain damage induced by UCB will cause an increase in NGB expression, the increasing NGB can inhibit neuron apoptosis in early BE phases. Therefore, promoting the expression of endogenous NGB, to act as a neuroprotective agent may be a potential treatment strategy for BE.

AbstractSeveral new 2,8‐diphenylpyrido[3,2‐g]quinoline‐4,6‐dicarbohydrazides were synthesized and copolyhydrazides based on them were obtained. Molecular weight, thermal, stress–strain and optical properties were investigated. It was shown that all polymer films exhibit significant luminescence in the 450–650 nm region, the profile and intensity of which depended on the nature and position of substituents in the phenylene fragment.
Morpho‐functional variation and response pattern of microglia through rodent ontogeny showing infant microglia as stable and adaptive than matured

Published: August 2021

AbstractMicroglia, myelo‐monocytic lineage cells, that enter in the developing brain at early embryonic stages and integrate in CNS, are involved in almost all neuroinflammatory conditions. We studied how microglia change their responses through the development and maturation of brain in normal physiological conditions using an ex situ model to delineate their age‐specific morpho‐functional responsiveness. Rapidly isolated microglia from different age‐matched rats were characterized with Iba1+/CD11b/c+/MHCclassII+, cultured, studied for cell‐cycle/proliferative potency, ROS generation and phagocytosis, viability and morphological analysis induced with GMCSF, MCSF, IL‐4, IL‐6, IL‐10, and IFN‐γ. The study showed marked differences in cellular properties, stability, and viability of microglia through ontogeny with specific patterns in their studied functions which were coherent with their in situ morpho‐functional attributes. Phagocytic behavior showed a notable shift from ROS independence to dependence toward maturation. Perinatal microglia were found persistent in ex situ environment and neonatal microglia qualified as the most potent and versatile responders for morpho‐functional variations under cytokine induced conditions. The study identified that microglia from infants were the most stable, adaptive, and better responders, which can perform as an ex situ model system to study microglial biology.

AbstractBackgroundSurvivor‐focused care for adolescent and young adult (AYA) childhood cancer survivors (CCS) often involves their parents. Recognizing the importance of parents in the ongoing care of CCS, our study sought to identify key aspects of a successful transition for CCS from pediatric‐ to adult‐centered care from the parent perspective.MethodsWe conducted qualitative interviews with 26 parents of CCS who were receiving care in the long‐term follow‐up (LTFU) clinic at a single institution. We used a semi‐structured interview protocol with the parents and conducted a thematic content analysis.ResultsUsing a constant comparison approach, data revealed three primary themes regarding parents’ perspectives toward ensuring a seamless transition from pediatric‐ to adult‐centered follow‐up care: (1) the transition needs to include seamless communication between all involved parties, (2) survivors need to demonstrate sufficient health care self‐efficacy in order to achieve a successful transition, and (3) the survivor‐focused care should include support for survivors’ overall well‐being, including financial and health insurance literacy.ConclusionsFor parents of AYA CCS, the optimal pediatric to adult care transition model should include mechanisms that facilitate communication between parents, CCS, and survivor‐focused providers while also supporting self‐efficacy and financial literacy as it relates to health insurance.
Patient‐targeted googling by psychological therapists: A narrative review of the literature and ethical implications

Published: August 2021

AbstractBackground“Patient‐Targeted Googling” (PTG) refers to a healthcare professional using the Internet to discover information about a patient. The present review explores PTG by psychological therapists. The review focused on the prevalence of PTG, how often consent is sought from the patient, and the motivations for and consequences of PTG.MethodA narrative literature review of published PTG studies was undertaken. Potentially eligible studies were identified by searching PsycINFO, PsycARTICLES, Psychology and Behavioural Sciences Collection, and MEDLINE. Results were screened for suitability for inclusion in the sample (n = 9). All studies were appraised for quality using a structured tool developed for this review.ResultsPTG prevalence rates ranged from 20% to 98%, with rates of non‐consent ranging from 60% to 84%. Motivations for PTG included curiosity, to gather new information and to verify existing information. Consequences of PTG included enhancing the therapist's sense of safety and causing harm to the therapeutic relationship.DiscussionCurrent literature on PTG is limited and focussed largely in the United States. This review revealed no published PTG studies including UK‐based psychological therapists, as well as issues in defining and operationalising PTG. Further research is needed to understand the prevalence of PTG by UK‐based psychological therapists, as well as the motivations behind, and consequences of, PTG. This evidence base will inform the development of PTG professional guidelines and training, neither of which currently exist for therapists practising in the UK. Both would be timely given the increasing move of the therapeutic frame to the online environment due to the COVID‐19 pandemic.

AbstractOriginally named according to their strict nucleophile specificity towards pyruvate, some pyruvate aldolases were demonstrated to be able to convert other nucleophiles. This study illustrates that the nucleophile 2‐oxopentanoate successfully reacted with various aldehydes and even ketones. Unknown aldols with a 3S configuration were then isolated, characterized, and their stereochemistries could be set as either 4R or 4S by choosing the appropriate aldolase.

AbstractThe development of an efficient method to patterning 2D MoS2 into a desired topographic structure is of particular importance to bridge the way towards the ultimate device. Herein, we demonstrate a patterning strategy by combining the electron beam lithography with the surface covalent functionalization. This strategy allows us to generate delicate MoS2 ribbon patterns with a minimum feature size of 2 μm in a high throughput rate. The patterned monolayer MoS2 domain consists of a spatially well‐defined heterophase homojunction and alternately distributed surface characteristics, which holds great interest for further exploration of MoS2 based devices.

AbstractThe influence of N‐substituents on the photovoltaic properties of singly bay‐linked perylene diimides (diPDIs) was systematically investigated to understand the aromatic‐aliphatic balance, which is beneficial for achieving high device performance in organic photovoltaic (OPV) systems. The synthesis of various N‐substituted diPDIs was successfully achieved using a newly developed one‐step procedure, resulting in sufficiently high yields. Detailed investigations of seven variants of diPDIs demonstrated that the primary alkyl substituents, particularly the 2‐ethylhexyl group, induce the self‐organized growth of thin films with high crystallinity. This is beneficial for enhancing the device performance of bulk heterojunction (BHJ) systems. The results presented herein reveal the important roles of alkyl side chains as hydrophobic solubilizing auxiliaries or primary determinants in the control of the active layer nanomorphology. This offers a valuable guideline that is essential for developing high‐performance organic semiconductor materials for future practical applications.

BackgroundFew evidence‐based psychosocial programs have been tested among adolescents and young adults (AYAs) with advanced cancer (AC), and early advance care planning (ACP) in this population is rare. The authors aimed to determine the feasibility and acceptability of 1) delivering an established resilience‐coaching program, and 2) integrating ACP into that program, among AYAs with AC.MethodsEligible AYAs were 12 to 24 years old, diagnosed with advanced cancer (recurrent/refractory disease or a diagnosis associated with <50% survival) and fluent in English. The Promoting Resilience in Stress Management–Advanced Cancer (PRISM‐AC) program included PRISM's standard sessions targeting stress‐management, goal‐setting, cognitive‐restructuring, and meaning‐making, delivered 1:1, 1 to 2 weeks apart, plus a new session involving elements of the AYA‐specific Voicing My Choices ACP guide. Participants completed surveys at baseline and 12 weeks, and exit interviews following study completion. Feasibility was defined as ≥70% completion of 1) standard 4‐session PRISM and 2) the new ACP session among those completing standard PRISM. Acceptability was defined qualitatively. Trajectories of patient‐reported anxiety, depression, and hope were examined descriptively.ResultsOf 50 eligible, approached AYAs, 26 (52%) enrolled and completed baseline surveys. The AYAs had a mean age of 16 years (SD = 2.7 years), and the majority were male (73%) and White/Caucasian (62%). Twenty‐two AYAs (85%) completed standard PRISM, and of those, 18 (82%) completed the ACP session. Feedback was highly positive; 100% and 91% described the overall and ACP programs as valuable, respectively. Anxiety, depression, and hope were unchanged after the program.ConclusionsResilience coaching followed by integrated ACP is feasible and acceptable for AYAs with AC. Participating did not cause distress or decrease hope.Lay Summary

Advance care planning (ACP) among adolescents and young adults (AYAs) with advanced cancer can be difficult to introduce.

We investigated whether it is feasible and acceptable to integrate ACP into an existing resilience‐coaching program for AYAs.

In this cohort study of 26 AYAs with advanced cancer, we found the Promoting Resilience in Stress Management–Advanced Cancer program to be feasible (≥70% intervention‐completion) and highly acceptable (positive post‐participation feedback, no evidence of participant‐distress).

We conclude that an intervention integrating resilience coaching and ACP is feasible and acceptable among AYAs with advanced cancer.

AbstractRare‐earth based luminescent materials are key functional components for the rational design of light‐conversion smart devices. Stable Eu3+‐doped strontium fluoride (SrF2) nanoparticles were prepared at room temperature in ethylene glycol. Their luminescence depends on the Eu content and changes after heat treatment. The crystallinity of heat‐treated material increases in comparison with as‐synthesized samples. Particles were investigated in solution using X‐ray diffraction, small‐angle X‐ray scattering, and X‐ray spectroscopy. After heat treatment, the size of the disordered nanoparticles increases together with a change of their local structure. Interstitial fluoride ions can be localized near Eu3+ ions. Therefore, non‐radiative relaxation from other mechanisms is decreased. Knowledge about the cation distribution is key information for understanding the luminescence properties of any material.
