Self-organization and competition in the immune response to
cancer invasion: a phase-orientated computational model of
oncogenesis
Authors: Adrian Oprisan Sorinel , Ardelean Aurel , Frangopol Petre T. 
Published: July 2002

Abstract
Motivation: Recent studies indicate that fractal dimensions can uncover aspects of cellular dynamics prior to pathological manifestation. In this respect we are interested in building a computational model of oncogenesis able to generate patterns with the same fractal dimension spectrum as the in vivo tumor.
Results: A new theoretical model incorporating a systemic view of oncogenesis in a computational model was proposed. The tumor growth is viewed as competition for resources between the two self-organizing subsystems: the neoplastic and the immune. Numerical simulations revealed that tumor escape can be uncovered in some earlier stage of the immune-system–tumor interaction using multifractal measures. The described computational model is able to simulate also the case of immune, surgical, chemical and radiotherapeutical treatment, as well as their effects.

ImportanceDuring an ongoing longitudinal cohort study, a casino opening created a natural cash transfer experiment. Some participating families received income supplements, and others did not. The children in this study are now adults.ObjectiveTo assess the long-term outcomes of family income supplements received in childhood.Design, Setting, and ParticipantsThis community-representative longitudinal cohort study set in western North Carolina assessed 1266 participants aged 9, 11, and 13 years at intake up to 11 times up to age 30 years from January 1993 to December 2015. Data were analyzed from January to December 2021.ExposuresIn 1996, a southeastern American Indian tribe implemented a cash transfer program of approximately $5000 annually per person for tribal members. Participants were compared on whether their family ever received the cash transfers (American Indian vs non–American Indian), the duration of the transfers, and annual amount based on the number of parents.Main Outcomes and MeasuresParticipants were followed up at ages 25 and 30 years to assess mental health symptoms, substance use symptoms, and functional outcomes (physical health, risky or illegal behaviors, and financial and social functioning).ResultsOf 1266 included participants, 320 (25.3%) were American Indian and 581 (49.7%) were female. Participants whose families received cash transfers during childhood reported fewer anxiety symptoms (relative risk [RR], 0.33; 95% CI, 0.25-0.44), depressive symptoms (RR, 0.51; 95% CI, 0.42-0.62), and cannabis symptoms (RR, 0.47; 95% CI, 0.27-0.82). They also reported improved physical health (RR, 0.66; 95% CI, 0.55-0.80) and financial functioning (RR, 0.78; 95% CI, 0.67-0.89) and fewer risky or illegal behaviors (RR, 0.57; 95% CI, 0.46-0.72) compared with those who did not receive the cash transfer. This pattern was supported by a series of heterogeneity analyses in which children whose families received the transfers for the longest duration and whose families received the largest transfer (due to having multiple American Indian parents) had the lowest levels of symptoms and the highest levels of functioning.Conclusions and RelevanceIn this natural experiment, a family cash transfer in childhood was associated with positive adult functioning 20 years later. The findings support programs like the child tax credit or universal basic income that provide cash directly to families with children.

AbstractThis study compared the reproducibility of chestwall and heart position using surface‐guided versus RPM (real‐time position management)‐guided deep inspiration breath hold (DIBH) radiotherapy for left sided breast cancer. Forty DIBH patients under either surface‐guided radiotherapy (SGRT) or RPM guidance were studied. For patients treated with tangential fields, reproducibility was measured as the displacements in central lung distance (CLD) and heart shadow to field edge distance (HFD) between pretreatment MV (megavoltage) images and planning DRRs (digitally reconstructed radiographs). For patients treated with volumetric modulated arc therapy (VMAT), sternum to isocenter (ISO) distance (StID), spine to rib edge distance (SpRD), and heart shadow to central axis (CAX) distance (HCD) between pretreatment kV images and planning DRRs were measured. These displacements were compared between SGRT and RPM‐guided DIBH. In tangential patients, the mean absolute displacements of SGRT versus RPM guidance were 0.19 versus 0.23 cm in CLD, and 0.33 versus 0.62 cm in HFD. With respect to planning DRR, heart appeared closer to the field edge by 0.04 cm with surface imaging versus 0.62 cm with RPM. In VMAT patients, the displacements of surface imaging versus RPM guidance were 0.21 versus 0.15 cm in StID, 0.24 versus 0.19 cm in SpRD, and 0.72 versus 0.41 cm in HCD. Heart appeared 0.41 cm further away from CAX with surface imaging, whereas 0.10 cm closer to field CAX with RPM. None of the differences between surface imaging and RPM guidance was statistically significant. In conclusion, the displacements of chestwall were small and were comparable with SGRT‐ or RPM‐guided DIBH. The position deviations of heart were larger than those of chestwall with SGRT or RPM. Although none of the differences between SGRT and RPM guidance were statistically significant, there was a trend that the position deviations of heart were smaller and more favorable with SGRT than with RPM guidance in tangential patients.

AbstractThe adhesion and proliferation of the bacteria on biomedical surfaces have posed a great threat to patients. Developing a class of renewable bactericidal surface with excellent bacteria release capability is crucial for elongating the service life of the biomedical devices. However, releasing the bacteria fast and frequently is usually a trade‐off with releasing them thoroughly and completely regenerating the surface. Herein, a temperature/light dual‐responsive antimicrobial coating is developed. The cyclodextrin (CD)‐contained antifouling macromolecule and the thermal‐responsive azobenzene‐contained macromolecule are assembled on the CDs‐modified surface, combined with additional silver nanoparticles. The surface exhibits low bacteria attachments of 9.30 × 105 cells cm−2 (E. coli, 120 h), high bactericidal efficiency of ≈96.3%. Meanwhile, ≈86.9% of the attached bacteria can be released from the surface rapidly in response to temperature, and the residues can be thoroughly removed by irradiating UV irradiation (release ratio ≈91.0%). The functions of the surface can be resumed by switching the host‐guest network via light regulation. The 3rd regenerated surface still maintains low bacteria density of 12.4 × 105 cells cm−2, bacteria killing ratio of ≈95.0%, and bacteria release rate of ≈95.7%. The work is supposed to provide a new insight into the design of multifunctional antibacterial surface and broaden their applications.
Unraveling the biosynthesis of penicillenols by genome mining polyketide synthase and nonribosomal peptide synthetase gene clusters in Penicillium citrinum
Authors: Nie Qiuyue , Guo Shuqi , Gao Xue 
Published: August 2022

AbstractPenicillenols belong to the family of tetramic acids with anticancer and antibacterial activities. Here, we report the discovery of the biosynthetic gene cluster (pnc) for penicillenol A1 and E in Penicillium citrinum ATCC9849 by genome mining. We discover the pnc cluster based on the results of gene deletions in P. citrinum and gene cluster heterologous expression in Aspergillus nidulans. We also propose the assembly line of the polyketide synthase module in PncA with the reduction by PncB provides a highly reduce polyketide chain to be further linked with an l‐threonine molecule and released from PncA to produce penicillenol E. Further formation of penicillenol A1 requires the N‐methylation of tetramic acid group by PncC. Our work deepens the understanding of the biosynthetic logic for N‐methylated tetramic acids and contributes to the discovery of new penicillenols by genome mining.

Published: August 2022

AbstractWe report herein a rare example of enantiodivergent aldehyde addition with β‐alkenyl allylic boronates via chiral Brønsted acid catalysis. 2,6‐Di‐9‐anthracenyl‐substituted chiral phosphoric acid‐catalyzed asymmetric allylation using β‐vinyl substituted allylic boronate gave alcohols withRabsolute configuration. The sense of asymmetric induction of the catalyst in these reactions is opposite to those in prior reports. Moreover, in the presence of the same acid catalyst, the reactions with β‐2‐propenyl substituted allylic boronate generated homoallylic alcohol products withSabsolute configuration. Unusual substrate‐catalyst C−H⋅⋅⋅π interactions in the favoured reaction transition state were identified as the origins of observed enantiodivergence through DFT computational studies.

Published: August 2022

AbstractFully substituted peptide/[60]fullerene hexakis‐adducts offer an excellent opportunity for multivalent protein recognition. In contrast to monofunctionalized fullerene hybrids, peptide/[60]fullerene hexakis‐adducts display multiple copies of a peptide in close spatial proximity and in the three dimensions of space. High affinity peptide binders for almost any target can be currently identified by in vitro evolution techniques, often providing synthetically simpler alternatives to natural ligands. However, despite the potential of peptide/[60]fullerene hexakis‐adducts, these promising conjugates have not been reported to date. Here we present a synthetic strategy for the construction of 3D multivalent hybrids that are able to bind with high affinity the E‐selectin. The here synthesized fully substituted peptide/[60]fullerene hybrids and their multivalent recognition of natural receptors constitute a proof of principle for their future application as functional biocompatible materials.

Published: August 2022

AbstractThe development of amine‐functionalized graphene quantum dots (GQDs) linked to mycolic acids (MAs) as a potential fluorescent biosensor to detect tuberculosis (TB) biomarkers is described. GQDs have attractive properties: high fluorescence, excellent biocompatibility, good water solubility, and low toxicity. MAs are lipids that are found in the cell wall of Mycobacterium tuberculosis that are antigenic, however, they are soluble only in chloroform and hexane. Chloroform‐soluble MAs were covalently linked to synthesized water‐soluble GQDs using an amide connection to create a potential fluorescent water‐soluble TB biosensor: MA‐GQDs. Fluorescence results showed that GQDs had a narrow emission spectrum with the highest emission at 440 nm, while MA‐GQDs had a broader spectrum with the highest emission at 470 nm, after exciting at 360 nm. The appearance of the peptide bond (amide linkage) in the Fourier‐transform infrared spectrum of MA‐GQDs confirmed the successful linking of MAs to GQDs. Powder X‐ray diffraction exhibited an increase in the number of peaks for MA‐GQDs relative to GQDs, suggesting that linking MAs to GQDs changed the crystal structure thereof. The linked MA‐GQDs showed good solubility in water, high fluorescence, and visual flow through a nitrocellulose membrane. These properties are promising for biomedical fluorescence sensing applications.

AbstractBackgroundEstimated life expectancy is one of the most important factors in determining treatment options for prostate cancer (PCa) patients. However, clinicians have few effective prognostic tools to individually assess survival in patients with PCa.MethodsWe screened 283,252 patients diagnosed with PCa from the Surveillance, Epidemiology, and End Results (SEER) database between 2004 and 2015, and randomly divided them into the training and validation groups. We used univariate and multivariate Cox analyses to identify independent prognostic factors and further established nomograms to predict 1‐, 3‐, 5‐, and 10‐year overall survival (OS) and cancer‐specific survival (CSS) for PCa patients. The prediction performance of nomograms was tested and externally validated by Concordance index (C‐index) and receiver operating characteristic (ROC) curve. Calibration curve and decision curve analysis (DCA) were used for internal validation. We further developed PCa prognostic scoring system based on the impact of available variables on survival.ResultsThe variables age, race, marital status, TNM stage, surgery method, radiotherapy, chemotherapy, PSA value, and Gleason score identified as independent prognostic factors were included in the survival nomograms. The results of training (C‐index: OS = 0.776, CSS = 0.889; AUC value: OS = 0.772–0.802, CSS = 0.892–0.936) and external validation (C‐index: OS = 0.759, CSS = 0.875) indicated our nomograms had good performance in predicting 1‐, 3‐, 5‐, and 10‐year OS and CSS prediction. Internal validation using the calibration curves and DCA curves demonstrated the effectiveness of the prediction models. The prognostic scoring system was more effective than the AJCC staging system in predicting the survival of PCa patients, especially for OS.ConclusionThe prognostic nomograms and prognostic scoring system have favorable performance in predicting OS and CSS of PCa patients. These individualized survival prediction tools may contribute to clinical decisions.

Published: August 2022

AbstractOmalizumab is a monoclonal antibody which targets immunoglobulin E. It is approved as an add‐on therapy for children with severe allergic asthma. Assessment of endotype and phenotype is necessary in order to correctly identify those patients who are most likely to respond to omalizumab. Children with severe asthma represent a complex heterogeneous group. This report outlines the background, management, and outcomes for two children initiated on omalizumab for severe allergic asthma in Children's Health Ireland at Tallaght. It demonstrates the difficulties faced by this cohort and the positive impact targeted biological therapy can have. Given the substantial cohort of children with asthma attending our tertiary center, it also indicates that comprehensive stepwise care can achieve adequate control in the vast majority of cases without the requirement for additional therapies.

Published: August 2022

AbstractBackgroundSchizophrenia (SCZ) is a complex psychiatric disorder associated with widespread alterations in the subcortical brain structure. Hemispheric asymmetries are a fundamental organizational principle of the human brain and relate to human psychological and behavioral characteristics. We aimed to explore the state of thalamic lateralization of SCZ.MethodsWe used voxel‐based morphometry (VBM) analysis, whole‐brain analysis of low‐frequency fluctuations (ALFF), fractional amplitude of low‐frequency fluctuations (fALFF), and resting‐state seed‐based functional connectivity (FC) analysis to investigate brain structural and functional deficits in SCZ. Also, we applied Pearson's correlation analysis to validate the correlation between Positive and Negative Symptom Scale (PANSS) scores and them.ResultsCompared with healthy controls, SCZ showed increased gray matter volume (GMV) of the left thalamus (t = 2.214, p = 0.029), which positively correlated with general psychosis (r = 0.423, p = 0.010). SCZ also showed increased ALFF in the putamen, the caudate nucleus, the thalamus, fALFF in the nucleus accumbens (NAc), and the caudate nucleus, and decreased fALFF in the precuneus. The left thalamus showed significantly weaker resting‐state FC with the amygdala and insula in SCZ. PANSS negative symptom scores were negatively correlated with the resting‐state FC between the thalamus and the insula (r = −0.414, p = 0.025).ConclusionsCollectively, these results suggest the possibility of aberrant laterality in the left thalamus and its FC with other related brain regions involved in the limbic system.

Published: August 2022

AbstractSustainable activated carbons (ACs) with high specific surface areas were successfully prepared from Termanalia arjuna (TA) biomass using H3PO4 as activating agent in a simple two‐step activation‐carbonization procedure. The effects of the synthesis parameters on their CO2 capture ability were also examined. The ratio of biomass to activating agent mass was 1:3, and the carbonization at 800 °C for 4 h exhibited a great potential for CO2 uptake. Maximum CO2 uptake was achieved under ambient conditions. Recyclability up to five cycles with marginal change could be achieved. The high performance of CO2 adsorption capacity is due to better microporosity and the presence of basic oxygen functional groups on the carbon surfaces.
A Novel Perspective on Surface Modification of LiNi0.5Co0.2Mn0.3O2 Cathode Material for Lithium‐Ion Batteries
Authors: Zhang Yang , Song Ye , Liu Lin , Ma Juanjuan , Liu Jie 
Published: August 2022

AbstractHigh nickel ternary cathode materials have caught much consideration because of their remarkable energy density, cycling stability, and low pollution. However, the materials with the instability of nickel are prone to crack during long‐term cycling processes; secondly, the residual alkali on the surface of materials would react with the electrolyte to corrode the electrode. To solve the above problems, the particle surface is usually coated with a protective layer of Al2O3 with good compatibility and thermal stability. But this method is relatively complicated and produces toxic organic solvents. In addition, the thick coating layer increases the charge transport resistance and decreases the lithium‐ion transport rate. Herein, we design a novel surface modification strategy: nano‐Al2O3 is loaded on the micro‐particles to form a series of stable points to improve the stability of the interface boundary, while the charge transmission impedance does not change significantly. As a result, the lithium‐ion transmission coefficient is greatly improved, whose capacity retention rate is still up to 86.17 % at 1 C after 100 cycles. This surface modification strategy is simple to operate and low in cost, which could meet industrial mass production.

Published: August 2022

BackgroundCancer survivors represent a population with high health care needs. If and how cancer survivors were affected by the first year of the coronavirus disease 2019 (COVID‐19) pandemic are largely unknown.MethodsUsing data from the nationwide, population‐based Behavioral Risk Factor Surveillance System (2017–2020), the authors investigated changes in health‐related measures during the COVID‐19 pandemic among cancer survivors and compared them with changes among adults without a cancer history in the United States. Sociodemographic and health‐related measures such as insurance coverage, employment status, health behaviors, and health status were self‐reported. Adjusted prevalence ratios of health‐related measures in 2020 versus 2017–2019 were calculated with multivariable logistic regressions and stratified by age group (18–64 vs. ≥65 years).ResultsAmong adults aged 18–64 years, the uninsured rate did not change significantly in 2020 despite increases in unemployment. The prevalence of unhealthy behaviors, such as insufficient sleep and smoking, decreased in 2020, and self‐rated health improved, regardless of cancer history. Notably, declines in smoking were larger among cancer survivors than nonelderly adults without a cancer history. Few changes were observed for adults aged ≥65 years.ConclusionsFurther research is needed to confirm the observed positive health behavior and health changes and to investigate the role of potential mechanisms, such as the national and regional policy responses to the pandemic regarding insurance coverage, unemployment benefits, and financial assistance. As polices related to the public health emergency expire, ongoing monitoring of longer term effects of the pandemic on cancer survivorship is warranted.

Published: August 2022

AbstractThis work reports the heterogenization of Rose Bengal dye on simple cellulose paper sheets (Cell‐RB) through copper‐catalyzed azide‐alkyne click ligation. The photocatalytic properties of Cell‐RB under green LED irradiation were evaluated in a series of dehydrogenative transformations for the functionalization of N‐aryltetrahydroisoquinolines and quinoxalin‐2(1H)‐ones. The excellent photocatalytic activities observed, associated to the ease of recovery with simple tweezers, highlight the strong assets of Cell‐RB with respect to traditional homogeneous organic photocatalysts.
