California is one of the only states actively managing trash in its rivers. Several community groups in Pinole, CA, USA collaborated on a Thriving Earth Exchange community science project. Its purpose was to assess the trash in Pinole Creek and identify policy development opportunities for the community. The key scientific questions were: how much trash was in the creek at the time of the study, what types of trash were most abundant, and where should the community be most concerned about trash in the creek? The team enlisted additional community volunteers at local events. A randomized sampling design and a community science-adapted version of The San Francisco Estuary Institute's Trash Monitoring Playbook was used to survey the trash in the creek. The Thriving Earth Team estimated there were 37 m 3 and 47,820 pieces of total trash in the creek channel with an average concentration of 2 m 3 per km and 2,697 pieces per km. The community gained an understanding of the scale of the problem. Plastic and single-use trash were most abundant, and the community members expressed high concern about plastic single-use food packaging and tobacco-related waste. The community identified locations in the creek where trash was abundant and prioritized follow-up study locations. Seven new recommendations were presented to the Pinole City Council. The City Council unanimously voted to further discuss ordinance-related recommendations. And that was when community science contributed to local policy development. A community science project was conducted in Pinole California to assess trash in Pinole Creek and propose policies for mitigation. The community surveyed trash in the creek and collected data in collaboration with a scientist. The community recommended several policies and actions to the Pinole City Council which were welcomed for advancement by the City Council.

In contrast to the vast Al-oxo molecular cluster chemistry, Al-based building units for metal–organic framework (MOF) construction are limited in structural diversity and complexity. Synthesis of single crystalline MOFs based on this “hard” metal is further complicated by the poor reversibility of the Al-organic coordination linkages. Here, a strategy to employ two kinds of linkages with distinct strength—strong Al-carboxylate linkage and weak Cu-pyrazol N linkage—gives FDM-91 (FDM=Fudan Materials) with gigantic Al 24 -based units. After replacing the weak moieties with organic linkers post-synthetically, two new stable MOFs with exceptional water harvesting capacity (up to 0.53 g g −1 ) and outstanding cycling performance are developed. Linkage-selective dissociation of FDM-91 further leads to the isolation of the Al 24 molecular clusters. The versatile chemistry performed here to reinforce or deconstruct MOFs provides a new way to make important extended and discrete structures.

Objective Little is known about the treatment of post-coronavirus disease 2019 (COVID-19) condition (PCC). This article examines the effectiveness of pharmacological interventions for treating people with PCC. Methods We searched Medline, EMBASE, ClinicalTrials. gov, and the International Clinical Trials Registry Platform. Two independent review authors screened citations, extracted data, and assessed the quality of the included studies. Due to heterogeneity in participants, interventions, and outcomes, we synthesized data narratively. We assessed the certainty of evidence using GRADE (Grading of Recommendations, Assessment, Development, and Evaluation). Participants People with PCC. Interventions Pharmacological interventions include corticosteroids, ivabradine, and inhaled hydrogen. Outcome Measures Olfactory function, sinus tachycardia, respiratory function. Results We identified 5 completed studies and 41 ongoing studies. Oral corticosteroids and olfactory training had higher olfactory scores after 10 weeks (MD: 5.60, 95% confidence interval [CI]: 1.41 to 9.79). Patients allocated oral corticosteroid, and nasal irrigation demonstrated improved recovery of olfactory function compared with the control group at 40 days (median 60, interquartile range [IQR]: 40 vs. median 30, IQR: 25, p = 0.024). Patients allocated to topical corticosteroid nasal spray and olfactory training had improved recovery of olfactory function after 2 weeks (median 7, IQR: 5−10 vs. median 5, IQR: 2−8, p = 0.08). Participants allocated to ivabradine had a greater mean reduction in heart rate compared with participants randomized to carvedilol (MD: −4.24, 95% CI: −10.09 to 1.61). Participants allocated to inhaled hydrogen therapy had an improved vital capacity (MD: 0.20, 95% CI: 0.07 to 0.33), forced expiratory volume (MD: 0.19, 95% CI: 0.04 to 0.34), 6-minute walk test (MD: 55.0, 95% CI: 36.04 to 73.96). Conclusions The evidence is of low to very low certainty about the effect of all pharmaco

Rigidly planar polycyclic phosphacycles featuring an internal dioxaphosphorane are promising photofunctional materials. However, the lack of efficient synthetic methods resulted in limited structural diversities which significantly hampered extensive study. Herein, we report a straightforward three-component synthesis of novel dioxaphosphorane-fused diphosphacycles with distinctive photophysical properties. Control experiments and theory calculations were performed to account for a plausible reaction mechanism. We also systematically investigated the structure-property relationships of these unprecedented platforms by combining experiments (X-ray analysis, optical and redox properties) and theoretical computations. Based on their unique structure and properties, a novel fluorescent switch for pH sensing was revealed by a dynamic ring-opening/ring-closing process.

The physics of mutual interaction of phonon quasiparticles with electronic spin degrees of freedom, leading to unusual transport phenomena of spin and heat, has been a subject of continuing interests for decades. Despite its pivotal role in transport processes, the effect of spin-phonon coupling on the phonon system, especially acoustic phonon properties, has so far been elusive. By means of inelastic neutron scattering and first-principles calculations, anomalous scattering spectral intensity from acoustic phonons was identified in the exemplary collinear antiferromagnetic nickel (II) oxide, unveiling strong spin-lattice correlations that renormalize the polarization of acoustic phonon. In particular, a clear magnetic scattering signature of the measured neutron scattering intensity from acoustic phonons is demonstrated by its momentum transfer and temperature dependences. The anomalous scattering intensity is successfully modeled with a modified magneto-vibrational scattering cross section, suggesting the presence of spin precession driven by phonon. The renormalization of phonon eigenvector is indicated by the observed "geometry-forbidden" neutron scattering intensity from transverse acoustic phonon. Importantly, the eigenvector renormalization cannot be explained by magnetostriction but instead, it could result from the coupling between phonon and local magnetization of ions.

Background Parkinson's disease (PD) is a prevalent, progressive neurodegenerative disease that has been widely treated using dopamine replacement therapy. However, this therapy does not prevent the progressive loss of dopaminergic neurons in the substantia nigra pars compacta. Clinical experience has shown that Chinese medicines (CMs) can alleviate the side effects of Western medicines for PD and improve the quality of life of patients. Objective This paper describes the collection and analysis of Professor Qiu Changlin's decoctions for PD and proposes new ideas on the Law of CM Clinical Formula Administration and Syndrome Differentiation of PD. Methods A database of Professor Qiu's prescriptions for PD patients of Zhejiang Provincial Hospital of Chinese Medicine over 5 years (January 2018 to May 2022) was established and analyzed using Microsoft Excel 2019 and SPSS Modeler 22.0. Results Frequency analysis of 1162 prescriptions comprising 232 CMs revealed 17 high-frequency CMs, including Shu Di Huang (Rehmanniae Radix Praeparata) and Chao Bai Shao (Paeoniae Radix Alba), and correlations among the CMs. The property (nature) of these CMs is warm, and the flavors are mainly bitter, sweet, and sour. Most enter the liver meridian. Based on cluster analysis, we obtained a core effective prescription that mainly comprises Tian Ma, Gou Teng Yin and Zuo Gui Wan. Conclusion The core effective prescription is expected to inspire new ideas for the administration of CM clinical formulas and syndrome differentiation in PD.

In this article, a tamarind seed gum-g-poly (acrylic acid-co-2-Acrylamido-2-methyl-1-propane sulfonic acid/polyvinyl alcohol) (TSG-g-P[AA-co-AMPS/PVA]) was prepared by aqueous solution polymerization. The Fourier transform infrared spectroscopy, scanning electron microscopy, and thermogravimetric analysis were used to characterize. The swelling behaviors, reusability and water-retention capabilities of hydrogels were evaluated. Under optimum synthesis conditions, the maximum equilibrium absorption of hydrogel was 1295 g·g −1 , 208 g·g −1 , 116 g·g −1 in deionized water, tap water and NaCl solution (0.9 wt%) respectively. Application of the hydrogel to soils increased their water-holding and fertilizer retention capacities. Furthermore, the excellent water retention anti-evaporation performance indicated that the hydrogel has the potential for applications in future sustainable agriculture and forestry.

Die Verteilung von Ladungen innerhalb pH-responsiver Wirkstoffträger beeinflusst nachweislich die Effizienz der Freisetzung, ist aber schwer zu kontrollieren und zu verifizieren. Wir stellen nun polyampholytische Nanogel-in-Mikrogel Kolloide (NiM−C) vor und zeigen, dass die Anordnung der Nanogele (NG) abhängig von den Synthesebedingungen ist. Dazu wurden pH-responsive Polyelektrolyt-NG durch Fällungspolymerisation synthetisiert und mit Fluoreszenzfarbstoffen markiert. Die NG wurden dann durch inverse Emulsionspolymerisation mittels tropfenbasierter Mikrofluidik in Mikrogel-Netzwerke (MG) integriert. Mit konfokaler Laser-Scanning-Mikroskopie (CLSM) wurde nachgewiesen, dass, je nach NG-Konzentration, pH-Wert und Ionenstärke, NiM−C mit unterschiedlichen NG-Anordnungen, wie Janus-artiger Phasentrennung, statistischer Verteilung und Kern-Schale-Architektur, erhalten werden. Unser Ansatz ist ein Meilenstein auf dem Weg zum simultanen Transport entgegengesetzt geladener Moleküle.
