Using a new polydentate Schiff-base ligand (H3L) we isolated three new tetranuclear isostructural lanthanide complexes with the general formula [LnNa2(L)4(DMF)4(H2O)2(AcO)2]·4DMF·2H2O [Ln = Dy (1), Ho (2), or Er (3)]. The structural characterization of the complexes reveals that the Na(+) ions are coordinated in the structure which gives them a structure-directing role in the molecule. The magnetic behavior of the systems was investigated by means of SQUID magnetometry which revealed that complex 1 exhibits single molecule magnet behavior at low temperatures which is enhanced by the application of a 2000 Oe static magnetic field...

Ethylene has impact on several physiological plant processes, including abscission, during which plants shed both their vegetative and reproductive organs. Cell separation and programmed cell death are involved in abscission, and these have also been correlated with ethylene action. However, the detailed spatiotemporal pattern of the molecular events during abscission remains unknown. We examined the expression of two tomato ACO genes, LeACO1, and LeACO4 that encode the last enzyme in ethylene biosynthesis, 1-aminocyclopropane-1-carboxylate oxidase (ACO), together with the expression of other abscission-associated genes involved in cell separation and programmed cell death, during a period of 0-12 h after abscission induction in the tomato flower pedicel abscission zone and nearby tissues...

Background.: Apnoeic oxygenation during anaesthesia has traditionally been limited by the rapid increase in carbon dioxide and subsequent decrease in pH. Using a Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) technique a slower increase in carbon dioxide than earlier studies was seen. Notably, apnoeic oxygenation using THRIVE has not been systematically evaluated with arterial blood gases or in patients undergoing laryngeal surgery. The primary aim of this study was to characterize changes in arterial P O 2 , P CO 2 and pH during apnoeic oxygenation using THRIVE under general anaesthesia...

Chronic Obstructive Pulmonary Disease (COPD) is a heterogeneous and complex disease with great morbidity and mortality. Despite the new developments in the managements of COPD, it was recognized that not all patients benefit from the available medications. Therefore, efforts to identify subgroups or phenotypes had been made in order to predict who will respond to a class of drugs for COPD. This review will discuss phenotypes, endotypes, and subgroups such as the frequent exacerbator, the one with systemic inflammation, the fast decliner, ACOS, and the one with co-morbidities and their impact on therapy...

Loss of function mutation of rice OsACOS12 impairs lipid metabolism-mediated anther cuticle and pollen wall formation, and interferes with tapetum programmed cell death, leading to male sterility. Acyl-CoA Synthetase (ACOS) is one of the enzymes activating fatty acids for various metabolic functions in plants. Here, we show that OsACOS12, an orthologue of Arabidopsis ACOS5 in rice, is crucial for rice fertility. Similar to acos5, osaocs12 mutant had no mature pollen. But unlike acos5, osaocs12 produced defective anthers lacking cutin and Ubisch bodies on the epidermal and inner surfaces, respectively, and delayed programmed cell death (PCD)-induced tapetum degradation...

A series of new lanthanide coordination supramolecular networks (CSNs) based on nalidixic acid (HNA) ligand were designed and synthesized. Their crystal structures were determined by single-crystal X-ray diffraction techniques. The thin films of these compounds were first successfully deposited on ITO glass via one-step electrophoretic deposition under mild conditions. The europium CSN film exhibits intense red emission and can act as a highly sensitive luminescent sensor for H2PO4- anions and ATP in aqueous solution...

INTRODUCTION: Patients with acute Achilles tendon rupture (ATR) display an extended healing process with varying clinical outcome. Poor microcirculatory blood flow has been suggested to be a significant factor for the healing process. However, whether microcirculation may predict healing outcome has been mostly unknown. Therefore, we investigated if blood flow in the Achilles tendon may be associated with patient-reported and functional outcomes after ATR. METHODS: In vivo laser Doppler flowmetry was used to assess microvascular blood flow bilateral in the Achilles tendons, during post-occlusive reactive hyperemia, of nine patients with acute total ATR at two weeks post-operatively...

The passage of the Affordable Care Act saw the creation of Accountable Care Organizations (ACOs), a new approach to healthcare delivery moving from fee-for-service toward population health. This paper presents a case study of the Memorial Hermann ACO (MHACO), launched in response to the Medicare Shared Savings Program, with goals to align physician and hospital incentives, practice evidence-based medicine, develop care coordination, and increase efficiency. Building blocks included an affiliated primary care network, a clinical integration program (involving shared electronic medical record platforms and quality data reporting), and significant investments in information technology...

Physicians' willingness to change how care is delivered is a key component of the ability of accountable care organizations (ACOs) to transform patient care. Yet physicians participating in Medicare ACOs are only moderately convinced that ACOs are an effective model for delivering cost-effective care.

Alternative payment models, such as accountable care organizations (ACOs), attempt to stimulate improvements in care delivery by better alignment of payer and provider incentives. However, limited attention has been paid to the physicians who actually deliver the care. In a large Medicare Pioneer ACO, we found that the number of beneficiaries per physician was low (median of seventy beneficiaries per physician, or less than 5 percent of a typical panel). We also found substantial physician turnover: More than half of physicians either joined (41 percent) or left (18 percent) the ACO during the 2012-14 contract period studied...
