The reaction of 249Bk(OH)4 with iodate under hydrothermal conditions results in the formation of Bk(IO3)3 as the major product with trace amounts of Bk(IO3)4 also crystallizing from the reaction mixture. The structure of Bk(IO3)3 consists of nine-coordinate BkIII cations that are bridged by iodate anions to yield layers that are isomorphous with those found for AmIII, CfIII, and with lanthanides that possess similar ionic radii. Bk(IO3)4 was expected to adopt the same structure as M(IO3)4 (M = Ce, Np, Pu), but instead parallels the structural chemistry of the smaller ZrIV cation...

Existing U.S. guidelines recommend that men with human immunodeficiency virus (HIV) infection should achieve virologic suppression* with effective antiretroviral therapy (ART) before attempting conception (1). Clinical studies have demonstrated that effective ART profoundly reduces the risk for HIV transmission (2-4). This information might be useful for counseling couples planning a pregnancy in which the man has HIV infection and the woman does not (i.e., a mixed HIV-status couple, often referred to as a serodiscordant couple)...

BACKGROUND: Mixed mood states in bipolar disorder are difficult to treat and when present indicate worse illness trajectories. Several medications are US Food and Drug Administration approved to treat mixed episodes; however, the clinical trials have been short term and rarely reported depression response. METHODS: We conducted a 5-month open-label trial examining the tolerability and efficacy of iloperidone for bipolar disorder mixed episodes. RESULTS: Mania and depression scores significantly improved over the course of the study for study completers (ie, 60%-68% improvement for manic symptoms and 41%-49% for depression symptoms)...

Ligand-functionalized, multivalent nanoparticles have been extensively studied for biomedical applications from imaging agents to drug delivery vehicles. However, the ligand cluster size is usually heterogeneous and the local valency is ill-defined. Here, we present a mixed micelle platform hierarchically self-assembled from a mixture of two amphiphilic 3-helix and 4-helix peptide-PEG-lipid hybrid conjugates. We demonstrate that the local multivalent ligand cluster size on the micelle surface can be controlled based on the coiled-coil oligomeric state...

OBJECTIVE: To examine the association between distance traveled for an abortion and site of postabortion care among low-income women. METHODS: We conducted a retrospective cohort study using claims data from 39,747 abortions covered by California's Medicaid program in 2011-2012. Primary outcomes were the odds of abortion-related visits to an emergency department (ED) and the original abortion site, and the secondary outcome was total abortion care costs. We used mixed-effects logistic regression adjusting for patient and abortion characteristics to examine the associations between distance traveled and subsequent abortion-related care at each location...

A new series of mixed valence perovskites, La0.75K0.25AMnTiO6 (A = Sr and Ba) nanocubes, have been synthesized by a mild hydrothermal route. From powder X-ray diffraction (XRD) analysis, the crystal structure of La0.75K0.25AMnTiO6 was solved as the orthorhombic symmetry (space group Pbnm) with a random A-site or B-site arrangement. The phase purity of the products was confirmed by ICP, SEM, and EDS analyses, and the oxidation states of the B-site metal atoms were determined to be +4 for Ti and +3/+4 for Mn from XPS results...

The mesophase formation in spin-coated periodic mesoporous organosilica (PMO) films aged at a controlled ambient humidity is investigated by time-resolved grazing-incidence small-angle X-ray scattering (GISAXS). The investigation demonstrates the existence of a tunable steady state in PMO spin-coated films. Thus, a film deposited at a relative humidity of 20 % has a lamellar mesophase, whereas a subsequent increase to 70 % leads to a phase transformation resulting in a P63 /mmc space group. On the other hand, an increase of the surfactant to organosilica molar ratio of between 0...

BACKGROUND: Opioid use disorder (OUD) is a major risk factor in the acquisition and transmission of HIV. Clinical practice guidelines call for the integration of HIV services in OUD treatment. This mixed methods study describes the integration of HIV services in buprenorphine treatment and examines whether HIV services vary by prescribers' medical specialty and across practice settings. METHODS: Data were obtained via qualitative interviews with buprenorphine experts (n = 21) and mailed surveys from US buprenorphine prescribers (n = 1174)...

LHCII, the major light harvesting antenna from plants, plays a dual role in photosynthesis. In low light it is a light-harvester, while in high light it is a quencher that protects the organism from photodamage. The switching mechanism between these two orthogonal conditions is mediated by protein dynamic disorder and photoprotective energy dissipation. The latter in particular is thought to occur in part via spectroscopically 'dark' states. We searched for such states in LHCII trimers from spinach, at both room temperature and at 77 K...

In recent years, significant attention has been given to polycyclic aromatic hydrocarbons (PAHs) exposures given their mutagenic and carcinogenic properties. However, levels of exposure and the key determinants of exposure are not well defined for the trucking industry. We measured ultrafine particle characteristics at 10 trucking terminals of varying operating size and location in the Northeast region of the United States using particle concentration counter and a surface area analyzer. Multivariate mixed-effects linear regression models were used to assess determinants of the concentration of total bound PAHs (tPAH), the total aerosol active surface area (AS), and the ratio tPAH/AS overall and individually within docks, trucking cabs, and administrative offices...

This interesting image illustrates a case of biopsy-proven pulmonary anthracosilicosis, a mixed dust pneumoconiosis, associated with Ga-PSMA-ligand uptake. Prostate-specific membrane antigen (PSMA) is an emerging imaging biomarker, with clinical application in evaluation of prostate cancer using Ga-PSMA-ligand PET/CT. Contrary to its name, PSMA is expressed in a number of other normal tissues and pathological states. Prostate-specific membrane antigen expression has been linked to tumor angiogenesis in various other epithelial neoplasms, as well as neovasculature associated with tissue regeneration and repair...
