Solvent-dependent Stabilization of a Charge Transfer State is the Key to Ultrafast Triplet State Formation in an Epigenetic DNA Nucleoside.

Chemistry 2021 Apr 15. Epub 2021 Apr 15.

East China Normal University, State Key Laboratory of Precision Spectroscopy, 3663 N. Zhongshan Rd., 200062, Shanghai, CHINA.

2'-Deoxy-5-formylcytidine (5fdCyd), a naturally occurring nucleoside found in mammalian DNA and mitochondrial RNA, exhibits important epigenetic functionality in biological processes. Because it efficiently generates triplet excited states, it is an endogenous photosensitizer capable of damaging DNA, but the intersystem crossing (ISC) mechanism responsible for ultrafast triplet state generation is poorly understood. In this study, time-resolved mid-IR spectroscopy and quantum mechanical calculations reveal the distinct ultrafast ISC mechanisms of 5fdCyd in water vs. Read More

Inhaled budesonide in the treatment of early COVID-19 (STOIC): a phase 2, open-label, randomised controlled trial.

Lancet Respir Med 2021 Apr 9. Epub 2021 Apr 9.

Nuffield Department of Clinical Medicine, University of Oxford, Oxford, UK; National Institute for Health Research (NIHR), Oxford Biomedical Research Centre, Oxford, UK. Electronic address:

Background: Multiple early reports of patients admitted to hospital with COVID-19 showed that patients with chronic respiratory disease were significantly under-represented in these cohorts. We hypothesised that the widespread use of inhaled glucocorticoids among these patients was responsible for this finding, and tested if inhaled glucocorticoids would be an effective treatment for early COVID-19.

Methods: We performed an open-label, parallel-group, phase 2, randomised controlled trial (Steroids in COVID-19; STOIC) of inhaled budesonide, compared with usual care, in adults within 7 days of the onset of mild COVID-19 symptoms. Read More

Painful temporomandibular joint overloading induces structural remodeling in the pericellular matrix of that joint's chondrocytes.

J Orthop Res 2021 Apr 8. Epub 2021 Apr 8.

Department of Bioengineering, University of Pennsylvania, Philadelphia, PA, 19104.

Mechanical stress to the TMJ is an important factor in cartilage degeneration, with both clinical and pre-clinical studies suggesting that repeated TMJ overloading could contribute to pain, inflammation, and/or structural damage in the joint. However, the relationship between pain severity and early signs of cartilage matrix microstructural dysregulation is not understood, limiting advancement of diagnoses and treatments for TMJ-OA. Changes in the pericellular matrix (PCM) surrounding chondrocytes may be early indicators of osteoarthritis. Read More

Thermal Properties of Surface-Modified and Cross-Linked Boron Nitride/Polyethylene Glycol Composite as Phase Change Material.

Polymers (Basel) 2021 Jan 31;13(3). Epub 2021 Jan 31.

School of Chemical Engineering & Materials Science, Chung-Ang University, Seoul 156-756, Korea.

A thermally conductive phase change material (PCM) was fabricated using polyethylene glycol (PEG) and boron nitride (BN). However, the interfacial adhesion between the BN and the PEG was poor, hindering efficient heat conduction. Grafting polyvinyl alcohol (PVA) onto the surface of BN and cross-linking due to hydrogen bonding between the hydroxyl groups in PVA and oxygen atoms in PEG improved the wettability of fillers.

Urol Oncol 2020 Dec 19. Epub 2020 Dec 19.

Department of Urology, University of Florida, Jacksonville, FL.

Background: Recent guidelines recommend active management of prostate cancer (CaP), especially high-risk disease, in elderly men. However, descriptive data from a large cohort with extended follow up on the risk of death from CaP in men diagnosed over 70 years of age and its relationship to Gleason score (GS) and serum prostate specific antigen (PSA) level is lacking.

Laboratory of Medical Investigation in Immunology (LIM48), Faculdade de Medicina, Hospital das Clínicas, University of São Paulo, São Paulo, Brazil.

Paracoccidioidomycosis (PCM) is an important endemic, systemic disease in Latin America caused by spp. This mycosis has been associated with high morbidity and sequels, and its clinical manifestations depend on the virulence of the infecting strain, the degree and type of immune response, infected tissues, and intrinsic characteristics of the host. The T helper(Th)1 and Th17/Th22 cells are related to resistance and control of infection, and a Th2/Th9 response is associated with disease susceptibility. Read More

Relationship between the radical-scavenging activity of selected flavonols and thermodynamic parameters calculated by density functional theory.

Free Radic Res 2020 Jul 7;54(7):535-539. Epub 2020 Sep 7.

Department of Life Science, Okayama University of Science, Okayama, Japan.

The relationship between radical-scavenging rate constants () in an aprotic medium and thermodynamic parameters calculated by density functional theory (DFT) was investigated for 7 flavonols, which are myricetin (Myr), quercetin (Que), morin (Mor), kaempferol (Kae), 2'-methylquercetin (2'-MeQue), 5'-methylquercetin (5'-MeQue), and 2',5'-dimethylquercetin (MeQue). The values were determined for the reaction between the flavonols and galvinoxyl radical used as a reactivity model of reactive oxygen species in deaerated acetonitrile at 298 K. The energy difference values (, HT: hydrogen transfer) between the flavonols and the corresponding radicals, which equal to the relative O-H bond dissociation energies of the OH groups in the flavonols and ionisation potentials (IP) were calculated by DFT at the B3LYP/6-31++G(d) level with C-PCM solvation model parameterised for acetonitrile.

Leibniz-Institut für Polymerforschung, Hohe Straße 6, D-01069 Dresden, Germany.

Microencapsulated phase change materials (PCMs) are attracting increasing attention as functional fillers in polymer matrices, to produce smart thermoregulating composites for applications in thermal energy storage (TES) and thermal management. In a polymer composite, the filler-matrix interfacial adhesion plays a fundamental role in the thermomechanical properties. Hence, this work aims to modify the surface of commercial PCM microcapsules through the formation of a layer of polydopamine (PDA), a bioinspired polymer that is emerging as a powerful tool to functionalize chemically inert surfaces due to its versatility and great adhesive potential in many different materials.

Nanoencapsulation of phase change materials (PCMs) and their applications in various fields for energy storage and management.

Adv Colloid Interface Sci 2020 Sep 31;283:102226. Epub 2020 Jul 31.

Department of Food Materials and Process Design Engineering, Gorgan University of Agricultural Sciences and Natural Resources, Gorgan, Iran. Electronic address:

Today, the use of phase change materials (PCMs) with remarkable properties for energy storage and development of engineering systems is an extremely important topic, due to enhanced demand for energy consumption. PCMs could be generally subdivided into solid-liquid, liquid-gas, solid-gas, and solid-solid groups. It should be noted that since there is no single excellent PCM that comprises all the suitable physical, chemical, kinetic, thermal, and economic properties, PCMs could be improved by incorporating some additives, modifying PCM structures, and optimizing the storage systems.

Polarizable continuum models provide an effective electrostatic embedding model for fragment-based chemical shift prediction in challenging systems.

J Comput Chem 2020 10 4;41(26):2251-2265. Epub 2020 Aug 4.

Department of Chemistry, Univeristy of California, Riverside, California, USA.

Ab initio nuclear magnetic resonance chemical shift prediction provides an important tool for interpreting and assigning experimental spectra, but it becomes computationally prohibitive in large systems. The computational costs can be reduced considerably by fragmentation of the large system into a series of contributions from many smaller subsystems. However, the presence of charged functional groups and the need to partition the system across covalent bonds create complications in biomolecules that typically require the use of large fragments and careful descriptions of the electrostatic environment.
