In 2015, the US Congress passed legislation entitled the Medicare Access and CHIP [Children's Health Insurance Program] Reauthorization Act (MACRA), which led to the formation of two reimbursement paradigms: the merit-based incentive payment system (MIPS) and alternative payment models (APMs). The MACRA effectively repealed the Centers for Medicare and Medicaid Services (CMS) sustainable growth rate (SGR) formula while combining several CMS quality-reporting programs. As such, MACRA represents an unparalleled acceleration toward reimbursement models that recognize value rather than volume...

Sub-micron phase-change contrast agents consist of a liquid perfluorocarbon core that can be vaporized by ultrasound (acoustic droplet vaporization) to generate contrast with excellent spatial and temporal control. When these agents, commonly referred to as nanodroplets, are formulated with cores of low boiling-point perfluorocarbons such as decafluorobutane and octafluoropropane, they can be activated with lowmechanical index imaging pulses for diagnostic applications. Since the utilization of minimum mechanical index is often desirable to avoid unnecessary biological effects, enabling consistent activation of these agents in an acoustic field is a challenge because the energy that must be delivered to achieve the vaporization threshold increases with depth due to attenuation...

Antimicrobial packaging materials (films or coatings) (APMs) have aroused great interest among the scientists or the experts specialized in material science, food science, packaging engineering, biology and chemistry. APMs have been used to package the food such as dairy products, poultry, meat (e.g. beef), salmon muscle, pastry dough, fresh pasta, bakery products, fruits, vegetables and beverages. Some materials have been already commercialized. The ability of APMs to extend the shelf-life of the food depends on the release rate of the antimicrobials (AMs) from the materials to the food...

Inhalation of metal(loid)s in ambient particulate matter (APM) represents a significant exposure pathway to humans. Although exposure assessment associated with this pathway is currently based on total metal(loid) content, a bioavailability (i.e. absorption in the systemic circulation) and/or bioaccessibility (i.e. solubility in simulated lung fluid) based approach may more accurately quantify exposure. Metal(loid) bioavailability-bioaccessibility assessment from APM is inherently complex and lacks consensus...

The HLA-I antigen processing machinery (APM) plays a crucial role in the anticancer immune response. The loss of surface expression of HLA-I molecules is particularly important as this enables tumor cells to evade recognition and lysis by cytotoxic T-lymphocytes. Transcriptional control of the APM genes is regulated by the nuclear factor kappa B (NF-κB). BCRFl is an Epstein-Barr virus homologue of human IL-10 (hIL-10) and is known as viral IL-10 (vIL-10). vIL-10 shares many immunosuppressive effects with hIL-10 but lacks the immunostimulatory effect of hIL-10...

A new paradigm for understanding immune-surveillance and immune escape in cancer is described here. Metastatic carcinomas express reduced levels of IL-33 and diminished levels of antigen processing machinery (APM), compared to syngeneic primary tumours. Complementation of IL-33 expression in metastatic tumours upregulates APM expression and functionality of major histocompatibility complex (MHC)-molecules, resulting in reduced tumour growth rates and a lower frequency of circulating tumour cells. Parallel studies in humans demonstrate that low tumour expression of IL-33 is an immune biomarker associated with recurrent prostate and kidney renal clear cell carcinomas...

During 11-18 September 2014, the size-resolved aerosol Cloud Condensation Nuclei (CCN) activity and mixing state were measured using Cloud Condensation Nuclei Counter (CCNC), Aerosol Particle Mass (APM) and Scanning Mobility Particle Sizer (SMPS). The results showed that aerosols mainly existed as an internal mixture. For 76, 111, 138 and 181 nm particles, black carbon (BC) accounted for 5.4%, 10%, l0.7% and 6.7% of the particle mass, but as high as 51%, 57%, 70% and 59% of the particle number concentrations, respectively, suggesting that BC was a type of important condensation nuclei in the atmosphere and made significant contributions to particle numbers...

Current alternative payment models (APMs) that move away from traditional fee-for-service payment often have explicit goals to reduce utilization in episodic settings, such as emergency departments (ED). We apply the new HHS payment reform taxonomy to illustrate a pathway to success for EDs in APMs. Despite the unique challenges faced by EDs, a variety of category 2 and 3 APMs may be applicable to EDs in the short- and long term to improve efficiency and value. Full and partially capitated models create incentives for longitudinal and episodic ED providers and payers to unite to create interventions to reduce costs...

Three-dimensional (3D) cell culture is a powerful in vitro technique to study the stratification and differentiation of keratinocytes. However, culture conditions, including culture media, supplements, and scaffolds (e.g., collagen gels with or without fibroblasts), can vary considerably. Here, we evaluated the roles of calcium, L-ascorbic acid phosphate magnesium salt n-hydrate (APM), and keratinocyte growth factor (KGF) in a chemically defined medium, EpiLife, in 3D cultures of primary human epidermal keratinocytes directly plated on polycarbonate filter inserts under airlifted or submerged conditions...

Proximally, the arrector pili muscle (APM) attaches to the follicular stem cell niche in the bulge, but its distal properties are comparatively unclear. In this work, a novel method employing an F-actin probe, phalloidin, was employed to visualize the APM anatomy. Phalloidin staining of the APM was validated by comparison with conventional antibodies/stains and by generating three-dimensional reconstructions. The proximal attachment of the APM to the bulge in 8 patients with androgenic alopecia was studied using Masson's trichrome stain...

Cancers can escape immunesurveillance by diminishing the expression of MHC class-I molecules (MHC-I) and components of the antigen-processing machinery (APM). Developing new approaches to reverse these defects could boost the efforts to restore antitumor immunity. Recent studies have shown that the expression of MHC-I and antigen-processing molecules is transcriptionally regulated by NOD-like receptor CARD domain containing 5 (NLRC5). To investigate whether NLRC5 could be used to improve tumor immunogenicity, we established stable lines of B16-F10 melanoma cells expressing NLRC5 (B16-5), the T cell co-stimulatory molecule CD80 (B16-CD80) or both (B16-5/80)...

Apocynaceae is a large family of tropical trees, shrubs and vines with most species producing white latex. Major metabolites of species are triterpenoids, iridoids, alkaloids and cardenolides, which are known for a wide range of biological and pharmacological activities such as cardioprotective, hepatoprotective, neuroprotective, anti-inflammatory, anticancer and antimalarial properties. Prompted by their anticancer and antimalarial properties, the current knowledge on ten genera (Allamanda, Alstonia, Calotropis, Catharanthus, Cerbera, Dyera, Kopsia, Nerium, Plumeria and Vallaris) is updated...

BACKGROUND: Roux-en-Y gastric bypass (RYGB) is associated with approximately 25 % weight loss failure, resulting in insufficient weight loss or weight regain. Strategies of revisional surgery focus on alteration of limb length, pouch or stoma size. Altering pouch size and outlet by adding laparoscopic adjustable gastric band (LAGB) might initiate further weight loss. The goal of this study is to review the safety and efficacy of LAGB after failed RYGB in a retrospective cohort of patients in our institute...
