BACKGROUND: Prior studies have demonstrated how price transparency lowers the test-ordering rates of trainees in hospitals, and physician-targeted price transparency efforts have been viewed as a promising cost-controlling strategy. OBJECTIVE: To examine the effect of displaying paid-price information on test-ordering rates for common imaging studies and procedures within an accountable care organization (ACO). DESIGN: Block randomized controlled trial for 1 year...

AIMS: Patients with an acute Achilles tendon rupture (ATR) take a long time to heal, have a high incidence of deep vein thrombosis (DVT) and widely variable functional outcomes. This variation in outcome may be explained by a lack of knowledge of adverse factors, and a subsequent shortage of appropriate interventions. PATIENTS AND METHODS: A total of 111 patients (95 men, 16 women; mean age 40.3, standard deviation 8.4) with an acute total ATR were prospectively assessed...

Orthogonal frequency-division multiplexing (OFDM) is a practical technology in visible light communication (VLC) for high-speed transmissions. However, one of its operational limitations is the peak-to-average power ratio (PAPR) of the transmitted signal. In this paper, we analyze the PAPR distributions of four VLC OFDM schemes, namely DC-biased optical OFDM (DCO-OFDM), asymmetrically clipped optical OFDM (ACO-OFDM), pulse amplitude modulated discrete multitone (PAM-DMT), and Flip-OFDM. Both lower and upper clippings are considered...

The advent of large-scale assessment, but also the more frequent use of longitudinal and multivariate approaches to measurement in psychological, educational, and sociological research, caused an increased demand for psychometrically sound short scales. Shortening scales economizes on valuable administration time, but might result in inadequate measures because reducing an item set could: a) change the internal structure of the measure, b) result in poorer reliability and measurement precision, c) deliver measures that cannot effectively discriminate between persons on the intended ability spectrum, and d) reduce test-criterion relations...

BACKGROUND: Sporopollenin is a major component of the pollen exine pattern. In Arabidopsis, acyl-CoA synthetase5 (ACOS5) is involved in sporopollenin precursor biosynthesis. In this study, we identified its orthologue, OsACOS12, in rice (Oryza sativa) and compared the functional conservation of ACOS in rice to Arabidopsis. RESULTS: Sequence analysis showed that OsACOS12 shares 63.9 % amino acid sequence identity with ACOS5. The osacos12 mutation caused by a pre-mature stop codon in LOC_Os04g24530 exhibits defective sexine resulting in a male sterile phenotype in rice...

High standards regarding Listeria monocytogenes control and consumer demands for food products without synthetic additives represent a challenge to food industry. We determined the antilisterial properties of an enriched acetogenin extract (EAE) from avocado seed, compared it to two commercial antimicrobials (one enriched in avocado acetogenins), and tested purified molecules. Acetogenin composition in pulp and seed of Hass avocado was quantified. EAE were obtained by two sequential centrifuge partition chromatography separations and molecules purified by preparative chromatography and quantified by HPLC-MS-TOF and HPLC-PDA...

To curtail increasing health care costs, the government has ushered in the era of the Accountable care organization (ACO). The purposes of this review are to evaluate the effects the ACO will have on the practice of interventional oncology and its role in cancer care and to explore methods to assimilate. Proposed action points include integration into the modern-day cancer center, adoption of an outpatient clinic, mandatory performance measures, and workflow and cost analysis. If adaptations are made, interventional oncology can continue its role in cancer treatment, will provide more effective care, and reach more patients in the new ACO...

María Alfonso, Alberto Tárraga, Pedro Molina
The synthesis and sensing properties of the nitrogen-rich ferrocene-imidazole-quinoxaline triad 1 decorated with two pyrrole rings have been described. Due to its ditopic nature, this molecule behaves as an ion-pair receptor for Ni(2+)cations and AcO(-) anions, although no affinity for either of the discrete ions is observed. It also displays the rare property consistent with the cooperative AND recognition of ion pairs. Thus, this receptor shows an important enhancement for binding AcO(-) anions when it is co-bound to Hg(2+)cations, whereas no affinity for the free receptor by the anion is observed...

Key findings. (1) ACOs at provider workforce extremes--few primary care providers or many specialists--performed worse on measures of preventive care quality relative to those with more PCPs and fewer specialists. (2) Upfront investment in ACO formation is associated with higher performance in preventive care quality. (3) ACOs with a higher proportion of minority beneficiaries performed worse on disease prevention measures than did ACOs with a lower proportion of minority beneficiaries. (4) ACOs facing barriers to quality performance may benefit from organizational characteristics such as electronic health record capabilities and hospital inclusion in the ACO...

Addressing nonmedical needs-such as the need for housing-is critical to advancing population health, improving the quality of care, and lowering the costs of care. Accountable care organizations (ACOs) are well positioned to address these needs. We used qualitative interviews with ACO leaders and site visits to examine how these organizations addressed the nonmedical needs of their patients, and the extent to which they did so. We developed a typology of medical and social services integration among ACOs that disentangles service and organizational integration...

A gene encoding 1-aminocyclopropane-1-carboxylic oxidase (ACO), which catalyzes the terminal step in ethylene biosynthesis, was isolated from Agrostis stolonifera. The AsACO gene is composed of 975 bp, encoding 324 amino acids. Three exons interspersed by two introns form AsACO gDNA. A BLAST search of the nucleotide sequence revealed a high level of similarity (79-91%) between AsACO and ACO genes of other plants. A phylogenetic tree was constructed via BLAST in the NCBI, and revealed the highest homology with wheat TaACO...

Phytohormone levels and the expression of genes encoding key enzymes participating in hormone biosynthetic pathways were investigated in pepper leaves inoculated with two different tobamoviruses. Obuda pepper virus (ObPV) inoculation led to the development of hypersensitive reaction (incompatible interaction), while Pepper mild mottle virus (PMMoV) inoculation resulted in a systemic, compatible interaction. ObPV-inoculation markedly increased not only the levels of salicylic acid (SA) (73-fold) and jasmonic acid (8-fold) but also those of abscisic acid, indole-3-acetic acid, indole-3-butyric acid, cis-zeatin, cis-zeatin-9-riboside and trans-zeatin-9-riboside in the inoculated pepper leaves 3 days post inoculation...

REVIEW
Stephanie A Christenson
PURPOSE OF REVIEW: The asthma-COPD overlap syndrome (ACOS) has reemerged in the medical literature. This review addresses our current understanding of ACOS as a clinical and biological entity and how new and existing therapies may be targeted to this group. RECENT FINDINGS: Many studies suggest that ACOS is common and associated with more morbidity than asthma and COPD in general. However, there is no consensus on an ACOS definition, likely due to the heterogeneity of the disease...

Multiple sequence alignment (MSA) is a widespread approach in computational biology and bioinformatics. MSA deals with how the sequences of nucleotides and amino acids are sequenced with possible alignment and minimum number of gaps between them, which directs to the functional, evolutionary and structural relationships among the sequences. Still the computation of MSA is a challenging task to provide an efficient accuracy and statistically significant results of alignments. In this work, the Bacterial Foraging Optimization Algorithm was employed to align the biological sequences which resulted in a non-dominated optimal solution...

Peroxisome proliferator-activated receptor-α (PPARα) is a member of the nuclear receptor superfamily involved in hepatocarcinogenesis in rodents. In previous studies on liver tumor tissues, PPARα mRNA expression was found to be significantly higher and overexpression of ERα inhibited the PPARα expression, cell-proliferation and also induced apoptosis in Hep3B cell. However, the role of ERβ is not known yet. Therefore, the aim of this study is to define the role of ERβ on PPARα in Hep3B cells. The effect of PPARα signaling cascade were monitored by inducing Hep3B cells by fenofibrate...
