For core excitation binding energies (CEBEs), we find that G0W0 predictions improve significantly over those from DFT if the G0W0 calculations are started from hybrid functionals with a high percentage of exact exchange.Stereoselectivity, a distinctive characteristic of lipase (EC 3.1.1.3), refers to the ability to differentiate between enantiomeric positions (sn-1 and sn-3) in triacylglycerol (TAG). This property has been determined based on the time course of enantiomeric excess of diacylglycerol (DAG) considering several consecutive steps of lipase-catalyzed hydrolysis of TAG; however, this concept is insufficient to represent the true nature of lipases which are capable of hydrolyzing the sn-2 position of TAG under the condition acyl migration occurs. Here, we suggest "integral stereoselectivity" to capture the preference of lipases for all ester groups of both TAG and DAG, as a novel index of the stereochemistry of lipase. To determine integral stereoselectivity, we established an analytical system based on the chromatographic resolution of dioleoylglycerol (DO) enantiomers and regioisomers. DO enantiomers were derivatized with 4-nitrophenyl isocyanate, and subsequently, resolved by chiral-phase high-performance liquid chromatography-ultraviolet. Regioisomers of monooleoylglycerol and DO were analyzed by HPLC with an evaporative light-scattering detector. Time-course analysis of three model lipases involved in the hydrolysis of trioleoylglycerol validated the analytical system designed to determine the integral stereoselectivity. As an accurate indicator of lipase stereochemistry reflecting all hydrolysis steps, integral stereoselectivity can expedite the development of lipases with unique stereochemistry from agricultural sources and their application to the food industry.By changing the parameters of fluorination reaction of bisaryl-platinum(II) complexes, each possible competitive pathway of Ar-Ar and Ar-F formation can be selectively controlled. It was discovered that steric hindrance, type of fluorinating reagent, and temperature of reaction are determinants for Ar-F vs Ar-Ar bond formation pathway from bisaryl-fluoro-platinum(IV) complexes. The combination of bulky ligands such as mesityl with Selectfluor at RT leads to Ar-F bond formation in the presence of possible Ar-Ar formation.Nanoparticles have been used for effectively delivering imaging agents and therapeutic drugs into stem cells. However, nanoparticles are not sufficiently internalized into stem cells; thus, new delivery method of nanoparticles into stem cells is urgently needed. Estradiol in vitro Herein, we develop bicyclo[6.1.0]nonyne (BCN)-conjugated gold nanoparticles (BCN-AuNPs), which can be bioorthogonally conjugated to azide (-N3) groups on the surface of metabolically engineered stem cells via bioorthogonal click chemistry. For incorporating azide groups on the cell surface, first, human adipose-derived mesenchymal stem cells (hMSCs) were metabolically engineered with N-azidoacetylmannosamine-tetraacylated (Ac4ManNAz). Second, clickable BCN-AuNPs were bioorthogonally conjugated to azide groups on Ac4ManNAz-treated hMSCs. Importantly, a large amount of BCN-AuNPs was specifically conjugated to metabolically engineered hMSCs and then internalized rapidly into stem cells through membrane turnover mechanism, compared to the conventional nanoparticle-derived endocytosis mechanism. Furthermore, BCN-AuNPs entrapped in endosomal/lysosomal compartment could escape efficiently to the cytoplasm of metabolically engineered stem cells. Finally, BCN-AuNPs in stem cells were very safe, and they did not affect stem cell functions, such as self-renewal and differentiation capacity. These bioorthogonally conjugated nanoparticles on metabolically engineered stem cells can enhance the cellular uptake of nanoparticles via bioorthogonal conjugation mechanism.Fibromyalgia is a musculoskeletal pain of different parts of the body, which is also associated with fatigue, lack of sleep, cognition deficits, family history, gender bias, and other disorders such as osteoarthritis and rheumatoid arthritis. It is generally initiated after trauma, surgery, infection, or stress. Fibromyalgia often coexists with several other conditions or disorders such as temporomandibular joint disorders, bowel and bladder syndrome, anxiety, depression, headaches, and interstitial cystitis. While there is no permanent cure for fibromyalgia, some interventions are available with multiple side effects. rTMS (repetitive transcranial magnetic stimulation), a noninvasive management strategy is used widely for various pain-related etiologies including fibromyalgia in both the laboratory and clinical settings. In this Review, we discuss the role and mechanism of action of rTMS in fibromyalgia patients and on associated comorbidities including anxiety, pain, depression, neurotransmitter alterations, sleep disorders, and overall quality of life of the patients suffering from this chronic problem. We also provide an update on the rTMS application in the clinical trials of fibromyalgia patients and prospective management therapy for multiple problems that these patients suffer.ConspectusWith the development of solid-state lighting technology, efficient light sources that combine high brightness, wide range, and good stability are in high demand for next-generation lighting and displays. Metal halides are emerging as promising luminescent materials due to their versatility for desirable light emission manipulations. This is because the optical activity of the metal halide material depends on the metal halide structural unit and the organic ions or coordinated organic ligands. The different assembly of metal halide units and organic parts can enable versatile light emissions, such as lead halide perovskites (LHPs) and copper halide-organic hybrids. Impressively, the external quantum efficiency of the LHP based light-emitting diodes (LEDs) has improved significantly from 0.1% to over 20% in just five years. With this great progress, the structural lability and toxicity of the LHPs are now the critical issues that need to be addressed for practical applications. These issues are mainly rooted in the intrinsic lead composition and low formation energy crystal structure of the widely adopted LHPs.
