During hospitalization in the intensive care unit of ICFUH, female patients were less likely to be treated with statins than male patients (30.1 vs. 57.5 DDD/100 BD, P<0.05). There was no difference between sexes regarding the use of antihypertensive drugs. Women were less likely to be treated by antiplatelet therapy, more precisely by acetylsalicylic acid (30.4 vs. 36.9 DDD/100 BD, P<0.05).

Our study indicates that there were sex differences in CV drug administration in ICFUH. Presuming that drugs used during hospitalization were at least partially a continuation of the previous therapy prescribed by the family doctor, it is possible that such differences exist in primary care.

Herein, we describe the conjugation of photosensitizers and protein ligands (PS-Degrons), as an activable targeted protein degradation platform. PS-Degrons are capable of degrading protein of interest via light-triggered 1O2, which is orthogonal and complementary to existing technologies. This generalizable platform allows controllable knockdown of the target protein with high spatiotemporal precision. Our lead compound PSDalpha induces a complete degradation of human estrogen receptor α (ERα) under visible light. The high degrading ERα efficacy of PSDalpha enables an excellent anti-proliferation performance on MCF-7 cells. Our results establish a modular strategy for the controllable degradation of target proteins, which can hopefully overcome the systemic toxicity in clinical treatment of PROTACs. We anticipate that PS-Degrons would open a new chapter for biochemical research and for the therapeutics.The construction, critical evaluation, and performance assessment of a medium-pressure (2-13 mbar), high-temperature chemical ionization (CI) source for application in GC-MS is described. The ion source is coupled to a commercial time-of-flight (TOF) mass analyzer. Reagent ions are generated in a two staged process. The first stage uses a filament free, helical resonator plasma (HRP) driven ion source for H3+ generation. 1,4-Diaminobutane Reagent gases, for example, nitrogen, isobutane, and methane are added in a second stage to the H3+ stream, which leads to the formation of final protonation reagents. The GC effluent is added subsequently to the reagent ion gas stream. Designed for the hyphenation with gas chromatography, this GC-CI-TOFMS combination produces GC limited Gaussian peak shapes even for high boiling point compounds. Limits of detection for the compounds investigated are determined as 0.4-1.2 pg on column with nitrogen, 0.6-12.6 pg with isobutane, and 2 pg to >25 pg with methane as reagent gas, respectively. An EPA 8270 LCS mix containing 78 main EPA pollutants is used to evaluate the selectivity of the different reagent ions. Using nitrogen as reagent gas, 74 of 78 compounds are detected. In comparison, 41 of 78 compounds and 62 of 78 compounds are detected with isobutane or methane as CI reagent gas, respectively.Pathogenic bacterial infections in freshwater-farmed fish have high morbidity and mortality. As an effective broad spectrum antibacterial agent, silver nanoparticles (AgNPs) have great application potential in the field of aquaculture. However, due to the easy aggregation and oxidation properties of AgNPs, their practical applications are rather limited. Herein, nanocomposites of AgNPs and carbon nanodots (AgNPs@C-dots) were synthesized by using carbon nanodots as a reductant and a stabilizer. Their antibacterial activity and biosafety were systematically investigated. AgNPs@C-dots exhibit superior aggregation stability, excellent biocompatibility, and enhanced antibacterial activity compared to common AgNPs (reduced by sodium citrate). In vitro antibacterial results show that AgNPs@C-dots can completely kill Aeromonas salmonicida at a concentration of 9.5 μg mL-1. The possible antibacterial mechanism of AgNPs@C-dots was thoroughly clarified by scanning electron microscopy, gel imaging, and laser scanning confocal imaging. The AgNPs@C-dots have been successfully applied to enhance the resistance of zebrafish to A. salmonicida with satisfactory results. Moreover, AgNPs@C-dots did not result in detectable residues of silver in the muscles after 30 days of exposure. It is well demonstrated that AgNPs@C-dots could be used for the development of antibacterial agents in aquaculture.Solar-initiated CO2 reduction is significant for green energy development. Herein, we have prepared a new mesoporous/microporous porphyrin metal-organic framework (MOF), IHEP-20, loaded with polymetallic oxygen clusters (POMs) to form a composite material POMs@IHEP-20 for visible-light-driven photocatalytic CO2 reduction. The as-made composite material exhibits good stability in water from pH 0 to 11. After POMs were introduced to IHEP-20, they showed superior activity toward photocatalytic CO2 reduction with a CO production rate of 970 μmol·g-1·h-1, which is 3.27 times higher than that of pristine IHEP-20. This study opens a new door for the design and synthesis of high-performance catalysts for the photocatalytic reduction of CO2.Although worm-like micelles were invented 35 years ago, its formation pathway remains unclear. Inspired by the fact that a single molecular level experiment could provide meaningful and additional information, especially in a heterogeneous subpopulation, herein, we present a single molecular level study on the formation of wormlike micelles by cetyltrimethylammonium bromide (CTAB) and sodium salicylate (NaSal) in water. Our results indicated a coexistence of normal spherical micelles along with a big wormlike micelle in its formation path. More interestingly, we have two unique insights into the formation mechanism, which are inaccessible in ensemble averaged experiments (i) at extremely low concentrations of the surfactant, [CTAB]/[NaSal] ∼ 0.06, the wormlike micelle attains the highest size; and (ii) the relative concentration of wormlike micelles is highest when [CTAB]/[NaSal] ∼ 2.Agro-industrial wastes have gained great attention as a possible source of bioactive compounds, which may be utilized in various industries including pharmaceutics, cosmetics, and food. The food processing industry creates a vast amount of waste which contains valuable compounds such as phenolics. Polyphenols can be found in soluble (extractable or free), conjugated, and insoluble-bound forms in various plant-based foods including fruits, vegetables, grains, nuts, and legumes. A substantial portion of phenolic compounds in agro-industrial wastes is present in the insoluble-bound form attached to the cell wall structural components and conjugated form which is covalently bound to sugar moieties. These bound phenolic compounds can be released from wastes by hydrolysis of the cell wall and glycosides by microbial enzymes. In addition, they can be converted into unique metabolites by methylation, carboxylation, sulfate conjugation, hydroxylation, and oxidation ability of microorganisms during fermentation. Enhancement of concentration and antioxidant activity of phenolic compounds and production of new metabolites from food wastes by microbial fermentation might be a promising way for better utilization of natural resources. This review provides an overview of mechanisms and factors affecting release and bioconversion of phenolic compounds in agro-industrial wastes by microbial fermentation.ConspectusLow-valent, low-coordinate 3d metal complexes represent a class of extraordinarily reactive compounds that can act as reagents and catalysts for challenging bond-activation reactions. The pursuit of these electron-deficient metal complexes in low oxidation states demands ancillary ligands capable of providing not only energetic stabilization but also sufficiently high steric bulk at the metal center. From this perspective, pincer ligands are particularly advantageous, as their prearranged, meridional coordination mode scaffolds the active center while the substituents of the peripheral donor atoms provide effective steric shielding for the coordination sphere. In a T-shaped geometry, the transition metal complexes possess a precisely defined vacant coordination site, which, combined with the often observed high-spin electron configuration, exhibits unusually high selectivity of these compounds with respect to one-electron redox chemistry. In light of the intractable reaction pathways typically obserion, this specific class of low-valent, low-coordinate complexes can be further diversified by introducing redox-active pincer ligands or building homobimetallic systems with two T-shaped units.This Account focuses on the discussion of selected examples of iron, cobalt, and nickel pincer complexes bearing a [P,N,P] or [N,N,N] donor set; however, their electronic structure and radical-type reactivity can be broadly extended to other pincer systems. The availability of various types of pincer ligands should allow fine-tuning of the reactivity of the T-shaped complexes. Given the unprecedented reactivity observed with these compounds, we expect the studies of T-shaped 3d metal complexes to be a fertile field for advancing base metal catalysis.We demonstrate fabrication of photodetectors in the UVC and UVA regions, based on surface engineering of Mn2+-doped ZnS Qdot. Mn2+-doped ZnS Qdot exhibited UVC detection with a responsivity of 0.3 ± 0.02 A·W-1 and detectivity of 1.7 ± 0.2 1011 Jones. Following this, the Qdot was surface modified with 8-hydroxyquinoline 5-sulfonic acid ligand, which resulted in the formation of a bluish green zinc quinolate complex (Zn(QS)2) at the Qdot surface (defined as the quantum dot complex, QDC) exhibiting overall white photoluminescence. The detector developed with QDC as the photoactive material exhibited a responsivity of 0.2 ± 0.02 A·W-1 and detectivity of 1.2 ± 0.2 1011 Jones in the UVA band. This shift in the detection band from UVC in Qdot to UVA in QDC, through the surface complexation mechanism, is a new approach for tuning spectral detection featured in this work. Besides, the self-powered response of both the detectors exhibited attractive photoelectric characteristics. The detectors were incorporated in a portable prototype to show their potential application toward selective UVC and UVA spectral detection. Additionally, the dual-mode emission of the QDC was used for data encryption and decryption.In this study, the effects of charge/discharge cycling on the thermal stability of LiNi0.8Co0.1Mn0.1O2, a high-Ni cathode material, are systematically investigated. X-ray diffraction measurements show that there is almost no change in the bulk structure of the cathode after cycling. However, X-ray absorption fine structure measurements indicate that Ni in the surface layer is reduced and stable rock-salt structures are formed. Differential scanning calorimetry (DSC) measurements show that the heat generation at the lowest temperature, which can trigger thermal runaway in batteries that use high-Ni cathodes, decreases significantly with the formation of rock-salt structures on the active material surface. This finding indicates that the rock-salt layer on the surface enhances the thermal stability of a high-Ni cathode. The change in the total heat generation with degradation, indicated by DSC measurements, is similar to that in the K-edge of Ni (i.e., the Ni valency), suggesting a strong correlation between the heat generation and crystal structure changes during cycling.
