#1
Jason A Wolf
In a healthcare world in which consumerism is no longer a question and value has claimed its place at center stage, leaders are called to think differently about how they operate and manage their organizations. Priorities are curving in new directions with shifts in policy, direction of dollars, and evolution of practice. At the center of this transition is an opportunity for healthcare leaders to recognize that patient experience is the new heart of healthcare leadership.To address quality, safety, service, cost, and population health outcomes, leaders must rethink how they understand and engage in experience efforts overall...

A set of high-affinity, high-specificity posttranslational modification (PTM) enrichment tools was developed to generate an unbiased snapshot of four key PTM profiles (tyrosine phosphorylation, acetylation, ubiquitination, and SUMOylation 2/3) for the clinically important protein programmed cell death ligand 1 (PD-L1). The results showed that epidermal growth factor (EGF) treatment induced tyrosine phosphorylation, acetylation, and ubiquitination of PD-L1. Further characterization of EGF-induced PD-L1 ubiquitination revealed a significant increase in mono- and multiubiquitination of PD-L1 that occurred on glycosylated PD-L1...

17β-Hydroxysteroid dehydrogenase type 2 (17β-HSD2) converts the active steroid hormones estradiol, testosterone, and 5α-dihydrotestosterone into their weakly active forms estrone, Δ(4)-androstene-3,17-dione, and 5α-androstane-3,17-dione, respectively, thereby regulating cell- and tissue-specific steroid action. As reduced levels of active steroids are associated with compromised bone health and onset of osteoporosis, 17β-HSD2 is considered a target for antiosteoporotic treatment. In this study, a pharmacophore model based on 17β-HSD2 inhibitors was applied to a virtual screening of various databases containing natural products in order to discover new lead structures from nature...

Janakiram Vaitla, Annette Bayer, Kathrin H Hopmann
Metal carbenes can undergo a myriad of synthetic transformations. Sulfur ylides are potential safe precursors of metal carbenes. Herein, we report cascade reactions that involve carbenoids derived from sulfoxonium ylides for the efficient and regioselective synthesis of indoles and pyrroles. The tandem action of iridium and Brønsted acid catalysts enables rapid assembly of the heterocycles from unmodified anilines or readily accessible enamines under microwave irradiation. The key mechanistic steps are the catalytic transformation of the sulfoxonium ylide into an iridium-carbene complex, followed by N-H or C-H functionalization of an aniline or enamine, respectively, and a final acid-catalyzed cyclization...

The effects of climate change on animal populations may be shaped by habitat characteristics at both micro- and macro-habitat level, however, empirical studies integrating these two scales of observation are lacking. As analyses of the effects of climate change commonly rely on data from a much larger scale than the microhabitat level organisms are affected at, this mismatch risks hampering progress in developing understanding of the details of the ecological and evolutionary responses of organisms and, ultimately, effective actions to preserve their populations...

Prokaryotic Argonaute proteins acquire guide strands derived from invading or mobile genetic elements, via an unknown pathway, to direct guide-dependent cleavage of foreign DNA. Here, we report that Argonaute from the archaeal organism Methanocaldococcus jannaschii (MjAgo) possesses two modes of action: the canonical guide-dependent endonuclease activity and a non-guided DNA endonuclease activity. The latter allows MjAgo to process long double-stranded DNAs, including circular plasmid DNAs and genomic DNAs...

Opioids are the gold-standard treatment for severe pain. However, potentially life-threatening side effects decrease the safety and effectiveness of these compounds. The addiction liability of these drugs has led to the current epidemic of opioid abuse in the US. Extensive research efforts have focused on trying to dissociate the analgesic properties of opioids from their undesirable side effects. Splice variants of the mu opioid receptor (MOR), which mediates opioid actions, have unique pharmacological properties and anatomic distributions that make them attractive candidates for therapeutic pain relief...

The introduction of bariatric surgery into clinical practice in the 1980s was followed by a relatively long watch-and-wait period before the very rapid accumulation of scientific literature, over the past decade, concerning its clinical effectiveness and safety and its mechanisms of action in the treatment of obesity. These surgical procedures now emerge as the most effective therapeutic modality to induce long-term remission of type 2 diabetes. Recent research has shed light on the potential mechanisms leading to the profound improvement of glucose homeostasis following most bariatric surgery procedures...

Methionine, together with Lys, is the most limiting AA for milk production in dairy cows. Besides its crucial role in milk production, Met and its derivate metabolites (e.g., glutathione, taurine, polyamines) are well-known immunonutrients in nonruminants, helping support and boost immune function and activity. In the present study, the effects of Met or choline, as its precursor, were investigated using an ex vivo whole blood challenge. The study involved 33 multiparous Holstein cows (from a larger cohort with a factorial arrangement of treatments) assigned from d -21 to +30 relative to parturition to a basal control (CON) diet, CON plus rumen-protected Met (MET, Smartamine M, Adisseo NA, Alpharetta, GA) at a rate of 0...

Microbot propulsion has seen increasing interest in recent years as artificial methods that overcome the well-established reversible and challenging nature of microscale fluid mechanics. While controlled movement is an important feature of microbot action, many envisioned applications also involve cargo transport where microbots must be able to load and unload contents on command while tolerating complex solution chemistry. Here we introduce a physical method that uses flexible and linked superparamagnetic colloidal chains, which can form closed rings or "lassos" in the presence of a planar rotating magnetic field...

The potential of single-walled carbon nanotubes (SWCNTs) to outperform silicon in electronic application was finally enabled through selective separation of semiconducting nanotubes from the as-synthesized statistical mix with polymeric dispersants. Such separation methods provide typically high semiconducting purity samples with narrow diameter distribution, i.e. almost single chiralities. But for a wide range of applications high purity mixtures of small and large diameters are sufficient or even required...

Biomarkers of brain amyloidosis and neurodegeneration/synaptic dysfunction are featured in recent diagnostic criteria for Alzheimer's disease. Several gaps in our knowledge, however, need to be filled before they can be adopted clinically. The aim of this article is to describe a roadmap, developed by a multidisciplinary task force, to rationally implement biomarkers for Italian Memory Clinics. This roadmap is based on a framework comprising 5 sequential phases: identification of leads for potentially useful biomarkers; development of clinical assays for clinical disease; evaluation of detection of early stages; definition of operating characteristics in relevant populations; and estimation of reducing disease-associated mortality, morbidity, and disability...

Food processing has been carried out since ancient times as a way to preserve and improve food nutritional and organoleptic properties. Although it has some undesirable consequences, such as the losses of some nutrients and the potential formation of toxic compounds, a wide range of benefits can be enumerated. Among them, the increased total antioxidant capacity of many processed foods has been known for long. This consequence has been related to both the release or increased availability of natural antioxidants and the de novo formation of substances with antioxidant properties as a consequence of the produced reactions...

Despite recent declines in mortality, malaria remains an important global health problem. New therapies are needed, including new drugs with novel modes of action compared to existing agents. Among new potential therapeutic targets for malaria, inhibition of parasitic histone deacetylases (HDACs) is a promising approach. Homology modeling of PfHDAC1, a known target of some anti-plasmodial HDAC inhibitors, revealed a unique threonine residue at the rim of the active site in close proximity to the location of the cap group of vorinostat-type HDAC inhibitors...

The focused library of new amides derived from 3,3-diphenyl-2,5-dioxo-pyrrolidin-1-yl-acetic acid (2a-t) and 3,3-diphenyl-propionic acid (3a-t) as potential anticonvulsant agents was synthesized. The final products were obtained in the amidation reaction of the given carboxylic acid (2, 3) with appropriate secondary amines in the presence of carbonyldiimidazole (CDI) as a coupling reagent. The initial anticonvulsant screening was performed in mice intraperitoneally (i.p.) using the "classical" maximal electroshock (MES) and subcutaneous pentylenetetrazole (scPTZ) seizure models, whereas the acute neurological toxicity was determined applying the rotarod test...

Torilin, a sesquiterpene isolated from the fruits of Torilis japonica, has shown antimicrobial, anticancer, and anti-inflammatory properties. However, data on the mechanism of torilin action against inflammation is limited. This study aimed at determining the anti-inflammatory property of torilin in LPS-induced inflammation using in vitro model of inflammation. We examined torilin's effect on expression levels of inflammatory mediators and cytokines in LPS-stimulated RAW 264.7 macrophages. The involvement of NF-kB and AP-1, MAP kinases, and adaptor proteins were assessed...

The validity of the application of mixture toxicity models, concentration addition (CA) and independent action (IA), to species sensitivity distribution (SSD) for calculation of multi-substance potentially affected fraction (msPAF) was examined in laboratory experiments. Toxicity assays of herbicide mixtures using 5 species of periphytic algae were conducted. Two mixture experiments were designed: a mixture of 5 herbicides with similar mode of action (MoA) and a mixture of 5 herbicides with dissimilar MoA, corresponding to the assumptions of the CA and IA models, respectively...
